In the use of the tablet press should pay attention to the problem

Matters needing attention

1. Do not remove the protective cover, safety cover and other devices on the machine and equipment, and install them properly when using.

2. The die shall be subject to strict flaw detection test and appearance inspection, without cracks, deformation, missing edges, suitable hardness and accurate size. If it is unqualified, it shall not be used to avoid serious damage to the machine.

3, particle powder should not be more than 100 mesh, because it will make the upper fly powder, under the impact of more leakage material, machine parts, easy to wear out, adhesive punching and raw material loss.

4, do not use raw materials that are not dry, because it will make the powder stick to the punch surface.

5, if there is a jump piece or stop, do not use your hand to take, so as not to cause hand injury accident.

6. Start the motor first, and then start the clutch after normal operation.

7. If abnormal vibration or abnormal noises are found in the machine during operation, stop the machine immediately for inspection.

8. During use, the pressure should not be too high. Generally, the load of the motor shall be used to determine that the heavy load current of the 380 volt motor shall not exceed 4 amperes when the motor is pressed.

9. Increased weight difference: in the process of pressure, the weight difference can exceed the limit specified in the pharmacopoeia before it is qualified. However, in the process of pressure, it is often found that the weight difference increases.

(1) the length of punch is not uniform, which can easily cause the difference in sheet weight to increase. Therefore, check each punch before use and then use it after use with calipers. If there is a small amount of individual pieces, the undershoot movement may fail, resulting in less filling of particles than the others.

(2) feeding hopper or granulator blockage: in the process of tablet pressing, if the particles used are small, sticky or wet, and the particles are occasionally mixed with cotton yarn, tablets and other foreign substances, the flow is not smooth, so that the particles added into the mold hole are reduced, affecting the tablet weight, if the tablet weight suddenly decreases, it is necessary to stop the inspection.

(3) particles cause weight changes: particles are too wet, too much fine powder, too large difference in particle thickness, and insufficient lubricant in particles can also cause weight changes, so the quality of particles should be improved.

(4) the cause of weight change, the overall situation is due to the failure of the tablet press or negligence in the work caused by, so in the process of the tablet press, should make good maintenance work, check whether there is damage to the parts, and at a certain interval of time (10-20 minutes) weigh the piece again, whether the piece weight is in accordance with the provisions.
