The difference between motor chip thickness and thinness

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 will change. You should carefully read the operation on the manual. If your tablet is heavy, the tablet will stick to the upper punch due to sticky punching or curling of the upper punch. At this time, the particles are filled into the die hole and pressed again to form a stack or the rising position of the lower punch is too low. The tablet cannot be ejected in time, and at the same time, the granules are added to the die hole and repeatedly pressurized. Pressing into laminations makes the tablet press vulnerable to damage. The problem of sticking and punching should be solved and the punch should be matched, the accuracy of the die assembly should be improved, and the failure of the tablet press should be eliminated. Troubleshooting of the pressure roller part: The pressure roller part can be divided into an upper pressure roller and a lower pressure roller, which is also a device to adjust the pressure of the tablet and increase protection.

Its common failure analysis and solutions:

1. Pressure roller wear: The outer circle of the pressure roller is severely worn, which will cause high resistance at the end of the punch, and the pressure roller must be replaced. When the inner hole of the pressure roller and the pressure roller shaft are severely worn, the pressure roller or the pressure roller shaft must be replaced. In addition, the pressure roller shaft sometimes breaks and deforms, mainly due to excessive pressure, most of which are caused by excessive adjustment due to difficult pressure of the material. At this time, it is necessary to replace the pressure roller shaft, adjust the material, and re-adjust the pressure.

2. Lack of oil or damage to the roller shaft bearing: Lubricate and maintain the roller shaft bearing regularly, and replace it if it is damaged. Regulation system (pressure regulation, filling regulation) regulation system includes pressure regulation system and filling regulation system.

Common failure analysis and solutions:

(1) Adjustment failure: In general, the adjustment failure is caused by the loosening of the handwheel screw, which makes the handwheel adjustment ineffective, or the adjustment worm gear jamming. At this time, check the adjustment handwheel and worm gear, and pass Tighten screws, lubricate the rotating worm gear and other measures. (2) The main reasons for the unstable filling are:

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

2) The wear of the punching die results in inconsistent sheet shapes or out of tolerance in total height;

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

4) The filling front rail in the filling rail assembly is severely worn, causing a jump, and the filling rail assembly should be replaced at this time;

5) The lifting rod in the filling rail assembly is severely worn, resulting in a large adjustment gap and causing the filling rail to shake. At this time, the filling rail assembly 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 turntable;

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

8) The dust suction effect of the down flush is poor, resulting in plug flushing.

3. The tablet is loose or the appearance quality of the tablet is not good: the tablet is loose or the appearance quality is not good, mainly caused by small pressure, uneven particles, low water content or material composition is not easy to compress, the solution is to adjust The pressure hand wheel increases the pressure, adjusts the composition of the particles and auxiliary materials, and the particles can be wetted with 75% ethanol when they are too dry.

4. The machine vibrates loudly when pressing the tablet: When pressing the tablet, the machine has a louder noise due to the imbalance of the pressure on both sides, adjust the pressure to solve it.
