The thickness of the motor chip is closely related to the material filling of the machine, and the position of the upper and lower pressing wheels can also change. You should carefully read the instructions on the operation. If your tablet is heavy, it may stick to the upper punch due to sticking or edge curling during the upper punch. At this time, the particles are filled into the mold hole and repeatedly pressed into a stack, or due to the low rising position of the lower punch, the tablet cannot be ejected in a timely manner. At the same time, the particles are added to the mold hole and repeatedly pressurized. Pressing into laminations makes the tablet press vulnerable to damage. It is necessary to solve the problem of sticking and punching, match the punch, improve the accuracy of the punching die, and troubleshoot the tablet press. Troubleshooting of the pressing wheel part: The pressing wheel part can be divided into upper pressing wheel and lower pressing wheel, and is also a device for adjusting tablet pressure and increasing protection.

Common fault analysis and solutions:

1. Pressure roller wear: The outer circle of the pressure roller is severely worn, which can cause high resistance at the end of the punch rod. Therefore, it is necessary to replace the pressure roller. When the inner hole of the pressure wheel and the pressure wheel shaft are severely worn, the pressure wheel or pressure wheel shaft must also be replaced. In addition, the roller shaft may sometimes break and deform, mainly due to excessive pressure, mostly due to excessive adjustment due to difficulty in pressing the material. At this time, it is necessary to replace the roller shaft, adjust the material, and readjust the pressure.

2. Lack of oil or damage to the roller shaft bearings: Regularly lubricate and maintain the roller shaft bearings, and replace them promptly in case of damage. The regulation system (pressure regulation, filling regulation) includes a pressure regulation system and a filling regulation system.

Common fault analysis and solutions:

(1) Adjustment failure: In general, adjustment failure is caused by the loosening of the handwheel screw, which makes the handwheel adjustment ineffective, or by the jamming of the adjusting worm gear. At this time, it is necessary to check the adjusting handwheel and worm gear, and can be solved by tightening the screw, lubricating the rotating worm gear, and other measures. (2) The main reasons for unstable filling are:

1) Material factors, uneven granulation or poor material fluidity;

2) The wear of the punching mold results in inconsistent sheet shape or overall height exceeding the tolerance;

3) Improper height adjustment of the hopper, insufficient filling of the grid behind the feeder;

4) The pre filling rail in the filling rail component is severely worn, causing bouncing. At this time, the filling rail component should be replaced;

5) The lifting rod in the filling rail component is severely worn, causing large adjustment clearance and causing the filling rail to shake. At this time, the filling rail component should be replaced;

6) The bottom surface of the feeder is severely worn, resulting in uneven clearance between the bottom surface of the feeder and the rotary table;

7) The powder scraper is severely worn, resulting in poor powder scraping effect. At this time, the powder scraper should be replaced;

8) The cleaning effect of downward flushing is poor, resulting in clogging.

3. Loose or poor appearance quality of tablets: Loose or poor appearance quality of tablets is mainly caused by low pressure, uneven particles, low water content, or difficulty in pressing material components. The solution is to adjust the pressure handwheel to increase pressure, adjust the composition of particles and auxiliary materials. If the particles are too dry, 75% ethanol can be sprayed for wetting.

4. There is a loud noise from the machine vibration during tablet pressing: The loud noise from the machine during tablet pressing is caused by the uneven pressure on both sides, which can be resolved by adjusting the pressure.
