How to operate the electric tablet press

Â First, use and characteristics
TDP-5 single punching machine can compress powdery raw materials into tablets, which can be widely used in pharmaceutical factories, chemical plants, hospitals, scientific research units, laboratory trial production and small batch production.
The machine has excellent performance, strong adaptability, convenient use, easy maintenance, small size, light weight, and can also be shaken when there is no electricity. This machine only installs a die, the filling depth of the material, the thickness of the tablet can be adjusted, can adapt to the requirements of the pharmaceutical industry to suppress various Chinese and Western medicine preparations and other industries to suppress the requirements of various similar products, and is widely accepted by users in various industries. Welcome.
Â
Second, the tablet press installation and wiring
1. The tablet press is mounted on a solid wooden workbench (also mounted on a concrete platform) with three M12 anchor screws. The paper from the countertop to the ground is about 600 mm (hand-operated, easy to operate). In order to facilitate the disassembly and repair, the position piece corresponding to the lower punch phase rod on the wooden workbench should also have a hole of about 35 mm in diameter.
2. Connect the motor to the ground wire before turning on the motor power to ensure safety. Then remove the V-belt, turn on the motor power, and start the motor to see if the motor rotates in the correct direction (the direction of rotation of the motor shaft should be opposite to the direction of the arrow on the shield or handwheel). If the direction of rotation is wrong, connect the cable separately and then triangle. The belt is installed.

Third, the loading and unloading of the die and the adjustment during tableting
1, the installation of the die
(1) Install the upper punch: loosen the lower punching fixing screw, turn the handwheel to raise the lower punching rod to the high position of the zui, and insert the lower punch into the hole of the lower punching rod (note that the notched slope of the lower punch is aligned with the lower punch) Tighten the screws and insert them into the bottom. Then tighten the lower fixing screws.
(2) Install the lower punch: Loosen the upper punching tightening nut, insert the upper punching rod into the hole of the upper punching rod, insert it to the end, use a wrench to clamp the hexagonal part of the upper part of the punching rod, and tighten the upper punching tightening nut.
(3) Install the middle mold: Loosen the middle mold fixing screw, put the mold in the hole of the middle mold plate, and make the under punch into
Press the middle mold hole and press the middle mold fixing screw. When placing the mold, pay attention to flatten the middle mold to avoid jamming when the skew is placed and damage the hole wall.
(4) Turn the handwheel by hand to slowly lower the upper punch into the middle die hole to observe whether there is collision or friction. If there is collision or friction, loosen the middle die plate fixing screws (two) and adjust the middle die table. The position of the plate is fixed so that the upper punch enters the middle die hole, and then the middle die plate fixing screw is tightened, so that the upper punch enters the middle die without collision or friction for the installation.
Â
2, the adjustment of the film
Turn the handwheel to raise the lower punch to the high position of the zui, and observe whether the lower punch surface is aligned with the plane of the middle mold (or the high or low will affect the output). If not, loosen the butterfly screw and loosen the gear press plate. Move the gear so that the lower punch surface is aligned with the plane of the middle die, then press the platen up and tighten the thumb screw.
At this point, the handwheel is shaken by hand, and the empty car runs for more than ten revolutions. If the machine is running normally, the pressure can be fed and the next step can be adjusted.
3, the adjustment of the filling depth (ie the adjustment of the weight of the tablet)
Loosen the thumb screw and loosen the gear platen. Turn the lower adjustment gear to the left to raise the lower punch, and the filling depth is reduced (the weight of the tablet is reduced). After adjusting, press the gear press plate up and tighten the butterfly screw.
4, the adjustment of the pressure (that is, the adjustment of the hardness of the tablet)
Loosen the connecting rod lock nut, turn the upper punching rod, turn to the left to move the upper punching rod downward, the pressure will increase, and the hardness of the pressed tablet will increase; otherwise, the pressure will decrease when the right turn, the hardness of the tablet will decrease. After adjusting, use a wrench to clamp the hexagonal part of the lower part of the punching rod, and still lock the connecting rod lock nut. At this point, the adjustment of the die is basically completed, and then the motor is tested for more than ten pieces, and the weight of the piece is checked, and the quality such as hardness and surface finish are qualified, and the production can be started. In the production process, the quality of the tablets must be checked at any time and adjusted in time.
5, the removal of the die
(1) Disassemble the upper punch: Unscrew the upper punching nut to pull out the upper punch. If the fit is tight, use the pliers to clamp the upper punch to pull it out, but be careful not to damage the punch edge.
(2) Disassemble the middle mold: Loosen the middle mold fixing screw, unscrew the lower punch to fix the screw, loosen the butterfly screw, and loosen the gear pressure plate. The transfer adjustment gear is used to raise the lower core rod by 10 millimeters, and the hand wheel is gently rotated, so that the lower punch core rod pushes out the middle mold part, and the middle mold is taken out by hand, if the middle mold fits closely in the hole, Do not use force to turn the hard top of the handwheel to avoid damage to the machine. At this time, the middle die plate must be removed and the middle mold removed.
(3) Disassemble the undershoot: first unscrew the lower punching set screw, then turn the handwheel to raise the lower punching rod to the high position of the zui, then the upper punch can be pulled out by hand. If it is tightly fitted, it can be pinched out with a pliers (be careful not to damage the punch edge).
(4) After the die is disassembled, the adjusting gear must be rotated to make the lower punching rod retreat about 10 mm. When the handwheel is turned to raise the lower punching rod to the high position of the zui, the top end is not higher than the bottom surface of the middle die plate. Do not ignore this step, so as to avoid the accident of the under impact of the core rod and the middle mold when it is used again. After the zui, the undercut fixing screw is still screwed on.
Â
Fourth, the removal and installation of the main parts
1. Disassembly of the middle die plate: Pull out the powder retaining plate, remove the hopper, unscrew the feeder set screw, unscrew the feeder fixed stud and spring, remove the feeder, and unscrew the middle die plate set screw and spring The gasket can be used to remove the middle platen. Installation: Refer to the reverse order above. Pay attention to alignment when screwing the feeder tightening screw. So as not to damage the wire hole of the feeder.
2. Disassembly of the upper punching rod: Loosen the connecting rod lock nut, turn the upper punching rod to disengage it from the connecting rod, turn the handwheel to raise the eccentric wheel shell to the high position of the zui, turn the eccentric shell to make the connecting rod swing to The upper punching rod can be pulled out from the upper side of the mold frame hole. Installation is performed in the reverse order described above.
3. Disassembly of the lower punching rod: Unscrew the lower punching fixing screw, the butterfly screw and the gear pressing plate rotate the adjusting gear, so that the lower punching core rod is lowered and taken out from the bottom hole of the fuselage. Installation: Refer to the reverse order above.
4. Connecting rod removal: first remove the upper punching rod, then remove the wire retaining ring on the connecting rod pin, take out the connecting rod pin, and then take off the connecting rod. Installation: Follow the reverse order above.
5. Large pulley, pinion and bridge axle disassembly: lower the V-belt, unscrew the right end of the bridge shaft and the washer (in the fuselage), and pull the large pulley together with the pinion and the bridge shaft. Then, the bridge shaft can be pulled out of the wheel hole. (The large pulley is integrated with the pinion and the bushing, and generally does not need to be disassembled). Installation: Refer to the reverse order above.
6. Spindle disassembly: The disassembly of the spindle should be carried out by two people. First remove the large pulley, then unscrew the nut to remove the lever, lever shaft and filling roller. (Remove the handwheel and camshaft if necessary) Remove the protective cover, unscrew the screws and washers, and use a wooden hammer to hit the non-working surface inside the large gear (not significant). Remove it (be careful not to lose the lifting roller), then hit the shaft end with a wooden hammer and a copper rod (be careful not to damage the shaft end screw hole), while holding the other end of the shaft and holding the eccentric wheel shell, slowly The spindle is removed. Installation: Refer to the reverse order above.

5. Lubrication and maintenance of the machine
1. Lubrication of the friction surfaces of all moving parts is an important part of ensuring the normal operation of the machine and prolonging the service life. In particular, if the main moving parts are dry and run in the absence of oil, they will be quickly damaged and cannot be used. Therefore, the tablet press is Before use, all oil cups, oil holes and friction surfaces must be lubricated, and the air is running so that the friction surfaces are covered with oil film before they can be put into use. In the future, each shift will be refueled on time, but it should not be too much for each refueling, so as to avoid spillage affecting cleaning and staining the tablets. The fueling parts and the number of fueling are shown in the following table:
2. Before each shift, check whether the screws are loose. During the work, always pay attention to the inspection. If it is loose, tighten it immediately to avoid malfunction.
Its main parts are:
Upper punch fastening nut, middle die fixing screw, lower punch fixing screw;
Connecting rod lock nut, connecting rod pin set screw;
Lifting fork lock nut (2) butterfly screws;
Middle mold table set screws (2 pieces).

3, before and after each shift, you must manually test a few pieces, and then open the electric tablet after no problem.
4. In the process of tableting, the quality of the die should be checked frequently. If there is a missing edge, a crack, or a serious damage, it will be replaced in time to avoid damage to the machine and affect the quality of the tablet.
5. After using each day, remove the remaining powder and wipe off all parts of the machine. If the deactivation time is long, the die must be removed, the friction surface and the working surface of the machine should be wiped clean, coated with anti-rust oil, and covered with dust-proof clothing; the die should be wiped clean and immersed in oil for storage.
6, regular inspection of the machine, 2 times a month.
Six, the use of precautions
1. Read the instructions carefully before using the machine for the first time before using it.
2. The machine can only be operated in a certain direction (see the arrow on the handwheel or the protective cover), and can not be reversed to avoid damage to the machine. Pay special attention to the adjustment of the tablet, do not neglect.
3. Belt tension adjustment: Adjust by two adjusting nuts on the electromechanical bottom plate. Pay attention to the lock after adjustment.
4. When the power is applied without power supply, the V-belt should be removed to reduce the resistance and wear. But don't remove the big pulley, because the large pulley has the effect of the flywheel.
5. When turning on the electric tablet, the rotating handle on the handwheel must be pulled down to avoid injury when running.
6. Regardless of manual pressing or electric pressing, the upper punching rod should be in the raised position and then restarted before starting. If the upper punch is started in the lowered position, the medium-molded piece is entered just after the start of the start. At this time, since the rotation speed of the machine has not risen and the inertia is small, the top car is likely to occur. (That is, after the upper punch enters the middle mold, it is "top dead" due to the resistance of the tablet, so that the machine stops running. When the top car is loaded, the machine is often damaged or the motor is damaged.)
7, after the car after the treatment
(1) When the car is in the process of electric pressing, the power should be turned off immediately to avoid burning the motor.
(2) When the top car is light, you can use the hand to turn the handwheel to make the upper punch pass the "dead point" (but not reversed, so that the feeder does not repeat the feeding, resulting in a more serious top car).
(3) When the vehicle is in serious position, loosen the connecting rod lock nut, turn the upper punch rod to raise it to reduce the pressure, and then turn the hand wheel to push the medicine out. Then re-adjust the hardness of the tablets.
8. Always check the quality of the tablets (sheet weight, hardness, surface finish, etc.) during the tableting process, and adjust them in time.
9. The batching granulation process before tableting has a great influence on the tableting. For example, the formulation of granules such as medicinal materials and slips, fillers, binders, etc. (the condition of the powder, the tightness of the granules, the proportion of the granules, the water content, etc.) directly affect the quality of the tablets. And often due to improper granulation of ingredients, it is impossible to form a piece or even damage the machine. Therefore, the machine cannot be used for tableting semi-solid or moist or non-granular fine powder. In the use, if the pressure has been adjusted to be quite large, it is still not pressed into pieces or pressed into pieces but appears too loose, layering, debris, pitting, falling powder and so on. It is necessary to find out the reasons and solve them from the aspects of ingredients. Do not blindly adjust to increase the pressure, and even damage the machine. In addition, although the hardness of the tablets extruded by some medicines is not large, it has a certain degree of toughness, and it is not bad for it to fall into the ground (usually it can be broken from the height of 1-1.2 meters on the ground), so it should be To meet the requirements of transportation and storage, do not focus on hardness alone, so as to avoid excessive pressure on the tablet and damage the machine.
