1. The quality of the die must be checked repeatedly before use, whether there are any defects, cracks, deformations and incomplete tightness, and whether the device is complete and good.
 

2. Check whether the powder of granular raw material is dry or not and the powder content in the granule should not exceed 10%. If not qualified, do not press hard, otherwise it will affect the normal operation of the machine and service life and material loss.

 

3. In the first test run, the indicator needle controlled by pressure regulator should be placed on 6. The powder should be poured into the bucket, and the test handwheel should be rotated by hand. At the same time, the filling and pressure should be adjusted so as to gradually increase the weight and hardness and softness of the tablet to meet the requirements of the finished product. Then the motor should be started first, then the clutch should be turned on and the production should be carried out. During the production process, the quality of the tablet should be regularly sampled and tested. It meets the requirements and adjusts it when necessary.

 

4. The choice of speed has a direct impact on the service life of the machine. Because the properties and viscosity of raw materials and the size and pressure of sheet diameter can not be uniformly regulated in use, the structure of this machine is continuously variable speed device. Slow speed is suitable for pressing minerals, plant grass, large sheet diameter, viscosity difference and other materials which are difficult to form rapidly. Quick for pressing and bonding, good lubricity and easy to form materials. Therefore, users must be based on the actual situation.

 

5. Managers must be familiar with the technical performance and internal structure of the machine, the principle of operation of the control mechanism and the working place should not be heard during operation, so as to prevent failure and damage the machine parts, so as to ensure safe production as the premise.

 

6. In use, we should always pay attention to whether the machine noise is normal or not. When there are screams and strange noises, we should stop to check and eliminate them. We should not reluctantly use them.

 

7. The protective cover and safety cover on the machine and equipment should not be dismantled, but should be installed when in use.

 

8. The die must undergo strict flaw detection test and shape inspection. It should be crack-free, deformed, edge-missing, suitable hardness and accurate size. If it is not qualified, do not use it, so as to avoid serious damage to the machine.

 

9. The feeding device is flat with the turntable, and its height is accurate. If it is high, it will leak powder. If it is low, the quality of tablets will be affected by the abrasion of copper chips.

 

10. Don't use the raw material with more fine powder, because it will make the upper flush powder more and the lower flush material more, which will affect the wear and tear of the machine parts and material loss.

 

11. Do not use non-drying materials, because it will make powder stick to the punch surface.

 

12. If there is a skip or stagnation in operation, do not take it by hand, so as not to cause hand injuries.

 

13. Driving should start the motor first, and then start the clutch after running normally.

 

14. If abnormal vibration or abnormal noise of the machine is found in use, stop immediately for inspection.

 

15. Use medium voltage not to be too large. Generally, the load of the motor is used to measure the overload current of the 380 volt motor when pressing the sheet. It is normal that the overload current of the motor should not exceed 4 amperes.

 

16. The difference of tablet weight increases. In the process of adding tablets, the difference of tablet weight can not exceed the limit prescribed by pharmacopoeia
