Welcome.
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 height of the work surface 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 punching 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. 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 the V-belt. 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 middle mold into the hole of the middle mold plate, and make the lower punch into the hole of the middle mold, press the bottom and then tighten 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 fixed position of the board allows the upper punch to enter
In the middle die hole, tighten the middle die plate fixing screw, and adjust it until the upper punch enters the middle die without collision or friction for the installation.
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.

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 must check whether the screws are loose, should also pay attention to check during the work process, if loose, immediately tighten, so as to avoid malfunction. The main parts are: upper punch fastening nut, middle die fixing screw, undershoot fixing screw; connecting rod lock nut, link pin set screw; lift fork lock nut (2) butterfly screw; Set fixing screws (2 pieces)
Refueling part and refueling times
Serial number | Refueling part | Lubricating oil | Number of refueling per shift |
1 | Spindle hole oil cup (2 pieces) | butter | 2-3 times |
2 | Eccentric wheel shell oil cup 1 | butter | 2-3 times |
3 | 1 bridge axle oil cup | butter | 2-3 times |
4 | Lifting the cam groove (ie the groove inside the large gear) | butter | Every week, check the surface of the groove to wipe off the dirt and add butter once. |
5 | Filling the groove of the cam | butter | Every shift inspection, depending on the situation |
6 | Gear tooth surface | butter | Every shift inspection, depending on the situation |
7 | Oil hole on connecting rod | Motor oil | 1 time |
8 | Swing pivot point of the lever | Motor oil | 1 time |
9 | Upper punching rod surface | Motor oil | 2 times |
10 | Lifting rod surface | Motor oil | 2 times |
3 , before and after each shift, you must manually test a few pieces, and then turn on 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, crack, or serious damage, it should be replaced in time to avoid damage to the machine and affect the quality of the tablet.
5 , after the use of each day should be taken out of the remaining particles, wipe the various parts of the machine. If the deactivation time is long, the die must be removed and the machine rubbed each side. Wipe the work surface, apply anti-rust oil, cover the dust-proof clothes; the die should be wiped clean and immersed in oil to save.
6. Check the machine regularly, twice 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), can not be reversed, so as not to damage the machine. Pay special attention to the adjustment of the tablet, do not neglect.
3 , belt elastic adjustment: through the two adjustment nut on the electromechanical bottom plate to adjust. 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 the electric tablet is pressed, the rotating handle on the hand wheel must be pulled down to avoid injury when running.
6. Regardless of manual or electric compression, the upper punch rod should be in the raised position and then restarted before starting. If in
When the upper punching piece is started in the lowered position, the medium-molded piece is entered just after starting, and at this time, since the rotation speed of the machine has not risen and the inertia is small, the situation of 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 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 medicines 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 tablets.
the amount. 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.
Seven, common faults
