Working principle of single stamping sheet machine: The characteristic of this single stamping sheet machine is a small desktop electric continuous tablet pressing machine, which can also be hand cranked. The pressed tablets have an average thickness, high glossiness, and do not require polishing. Due to the fact that a single stamping sheet machine only has one die, it is called a single stamping sheet machine; The filling depth and tablet thickness of the material can be adjusted.

Installation and wiring of tablet press:

1. The tablet press is installed on a sturdy wooden workbench (or can also be installed on a cement platform) and fixed with three sets of M12 foot screws. The body size paper from the workbench to the ground is about 600 millimeters (measured by hand and easy to operate). For the convenience of disassembly and repair, there should also be a hole with a diameter of about 35 millimeters on the wooden workbench corresponding to the position of the punch core pole.

2. Before connecting the motor power supply, first connect the motor to the ground wire to ensure safety. Remove the V-belt again, connect the motor power supply, and start the motor to observe whether the rotation direction of the motor is correct (the rotation direction of the motor shaft should be opposite to the direction of the arrow on the protective cover or handwheel). If the rotation direction is incorrect, connect the wires separately and then reinstall the V-belt.

Adjustment during loading and unloading of stamping dies and tablet pressing:

1. Installation of stamping dies

⑴ Installation of upper punch: Loosen the lower punch fixing screw, turn the handwheel to raise the lower punch core rod to the highest position, insert the lower punch rod into the hole of the lower punch core rod (pay attention to aligning the notch slope of the lower punch rod with the lower punch fastening screw and inserting it to the bottom), and finally tighten the lower punch fixing screw.

⑵ Install the lower punch: Loosen the upper punch fastening nut, insert the upper punch core rod into the hole of the upper punch core rod, insert it to the bottom, use a wrench to clamp the hexagonal lower part of the upper punch core rod, and tighten the upper punch fastening nut.

⑶ Install the middle mold: Loosen the fixing screws of the middle mold, place the middle mold flat into the hole of the middle mold platform, and at the same time punch it down into the hole of the middle mold, press it to the bottom, and then tighten the fixing screws of the middle mold. When placing the middle mold, it is important to keep it flat to avoid getting stuck when tilted and damaging the hole wall.

⑷ Rotate the handwheel by hand to slowly lower the upper punch into the middle mold hole, and observe for any collision or friction. If collision or friction occurs, loosen the fixing screws (two) of the middle mold plate, adjust the position of the fixing of the middle mold plate, so that the upper punch enters the middle mold hole, and then tighten the fixing screws of the middle mold plate. Adjust in this way until there is no collision or friction when the upper punch enters the middle mold, and then the installation is qualified.

2. Adjustment of Film Production

Rotate the handwheel to raise the lower punch to the highest position, and observe whether the lower punch surface is aligned with the middle mold plane (whether it is high or low will affect the chip output). If it is not aligned, loosen the butterfly screw, loosen the gear pressure plate to transfer the upper adjustment gear, so that the lower punch surface is aligned with the middle mold plane, and then continue to press the pressure plate and tighten the butterfly screw.

At this point, shake the handwheel with your hand and run the empty car for more than ten revolutions. If the machine is running normally, you can add materials for pressure testing and proceed to the next step of adjustment.

3. Adjustment of filling depth (i.e. adjustment of tablet weight)

Loosen the butterfly screw and loosen the gear pressure plate. Rotate the lower adjustment gear to the left to raise the lower punch rod, which reduces the filling depth (reduces the weight of the tablets). After adjustment, still press the gear teeth pressing plate and tighten the butterfly screw.

4. Adjustment of pressure (i.e. adjustment of tablet hardness)

Loosen the connecting rod locking nut, rotate the upper punch rod, and turn it to the left to move the upper punch rod downwards. This will increase the pressure and hardness of the pressed pills; On the contrary, turning right will reduce pressure and lower the hardness of the pill. After adjustment, use a wrench to hold the lower hexagonal part of the punch rod, while still locking the connecting rod locking nut. At this point, the adjustment of the punching die is basically completed. Then start the motor to test more than ten pieces, check the weight, hardness, and surface smoothness of the pieces. If they are qualified, they can be put into production. During the production process, it is still necessary to check the quality of the pills at any time and make timely adjustments.

5. Dismantling of stamping dies

⑴ Disassemble the upper punch: Loosen the upper punch fastening nut to pull out the upper punch rod. If the fit is tight, use pliers to clamp the upper punch rod and pull it out, but be careful not to damage the punch edge.

⑵ Disassemble the middle mold: Loosen the fixing screws of the middle mold, unscrew the downward punch fixing screws, loosen the butterfly screws, and loosen the gear pressure plate. Convey the adjustment of the gear to raise the lower punch core rodTen millimetersGently rotate the handwheel to push out a part of the middle mold with the lower punch rod, and then remove the middle mold by hand. If the middle mold fits tightly in the hole, do not forcefully rotate the handwheel to hard top it, in order to avoid damaging the parts. At this point, it is necessary to remove the middle mold plate and then take out the middle mold.

⑶ Disassemble the lower punch: First, unscrew the lower punch fixing screw, then turn the handwheel to raise the lower punch core rod to the highest position, and you can use your hand to pull out the upper punch rod. If the fit is tight, it can be clamped with pliers (be careful not to damage the edge of the punch).

After disassembling the punching die, it is still necessary to rotate and adjust the gear to make the lower punch core rod retreat by about10 millimetersWhen turning the handwheel to raise the lower punch rod to the highest position, its top should not be higher than the bottom surface of the middle mold plate (this step should not be ignored to avoid accidents where the lower punch rod collides with the middle mold when used again). Finally, tighten the downward fixing screw.

Lubrication and maintenance of the machine:

1. Lubrication of the friction surfaces of various moving parts is an important part of ensuring the normal operation and extending the service life of the machine, especially if the main moving parts are quickly damaged due to lack of oil during dry transfer and cannot be used. Therefore, before using the tablet press, all oil cups, oil holes, and friction surfaces must be lubricated with oil, and the machine must be run empty to cover all friction surfaces with an oil film before being put into use. From now on, refuel on time for each shift, but do not refuel too much each time to avoid spillage, affecting cleanliness, and contaminating pills. The refueling locations and refueling frequency are shown in the following table:

2. Before each shift, it is necessary to check whether all screws are loose. During the work process, regular attention should also be paid to checking. If there is any looseness, it should be tightened immediately to avoid malfunctions. Its main parts include: upper punch fastening nuts, middle die fixing screws, and lower punch fixing screws; Connecting rod locking nut, connecting rod pin tightening set screw; Lock nuts for lifting forks (2 pieces) butterfly screws; Two screws are used to fix the middle mold table.

working principle:

The downward punch of the single punch press enters the middle die hole from the lower end of the middle die, seals the bottom of the middle die hole, and fills the middle die hole with medication using a feeder. The upward punch enters the middle die hole from the upper end and descends a certain distance to press the medication powder into pieces; Subsequently, the upper punch rises and exits the hole, while the lower punch rises to push the tablet out of the middle mold hole, completing one tablet pressing process; Lower down to the original position and prepare to fill again.
