Common problems of blister

1. What should I do if the blister machine fails to start?
There are two reasons, one is that the input wire is not connected, and the other is that the input phase sequence is incorrect. Change the method: replace the wire, adjust the phase sequence, etc.
2. What if the heating brick of the blister does not heat? How to solve it?
There are four reasons, one is that the temperature regulating solid state is damaged, the second is that the heating brick is damaged, the third is that the heating brick fuse is blown, and the fourth is that the heating wire is loosened. The solution is to replace the solid state, replace the heating brick, more specialized fuse, and tighten the heating wire again.
3. What is the problem and how to solve the problem that the nozzle of the blister does not spray?
There are three reasons: the first nozzle has sundries, the second nozzle is not adjusted properly, and the third inlet is insufficient.
Solution: disassemble the nozzle, clean it, adjust the spray water level and adjust the appropriate air pressure.
4. What if the vacuum is abnormal?
Generally, the abnormal vacuum of the plastic suction machine is due to the insufficient air pressure of the vacuum valve and the lack of oil and inflexibility of the solenoid valve. Adjust the inlet pressure and clean or replace the solenoid valve.
5. What should I do if there is a phenomenon of sheet slipping in the sheet drawing of the blister machine?
The length and tightness of the two chains on the beam of the blister machine are different, and the width of the rake position is not appropriate when feeding the film. Adjust the length of the chain to ensure the same tightness, and adjust the size of the baffle wheel.
6. Why is there no bottom wind in the blister machine?
Generally, there is no bottom air in the blister because the coil is damaged, the circuit is disconnected, and the time for the bottom air is not set. Replace the coil, connect the circuit, and set the time.
7. In the production process of the blister machine, what is the reason for the poor demoulding (deformation) of the blister molding products?
8. How many systems does the blister machine have?
Heating system, forming system, vacuum system, air pressure system, cooling system, control system, etc.
9. In the process of blistering, the demoulding of the general blister is caused by inaccurate mold adjustment or processing, high mold temperature, insufficient or too high film strength.
Solution: It is recommended to improve the machining accuracy and avoid right angles in the mold design.
Reduce the mold temperature and extend the cooling time. The mold can be demoulded by mold blowing or vibration.
