When the quality of the blister formed by the aluminum plastic packaging machine is unqualified, the causes are as follows:
1. Whether the PVC film has problems and is qualified;
2. Whether the forming die is qualified, whether the forming hole is smooth, and whether the air hole is unobstructed;
3. Whether PVC is stuck on the surface of the heating device;
4. Whether the temperature of the heating device of the aluminum plastic packaging machine is too high or too low;
5. Whether the compressed air for flat positive pressure forming is clean and dry;
6. Whether the cooling system of the forming die works normally and effectively;
7. Whether the pressure and flow of flat positive pressure forming can reach the normal value, and whether the pipeline has abnormal loss;
8. Whether the cooling system of the forming die works normally and effectively;
9. Whether the vacuum degree and exhaust rate of roller negative pressure forming can reach the normal value, and whether the pipeline has abnormal loss;
10. Whether the flat positive pressure forming die clamps the PVC tape in parallel and whether there is air leakage.
In the daily operation knowledge of the aluminum plastic packaging machine, you must understand the structural principle of the machine for the operation work. The roller of the ejector pin seat is driven by the cam, the up and down travel, the position of the upper cover template is fixed, and the blister is in a bad state.
Pay attention to the lower forming die or the heat seal to the top dead center, and tighten the stud nuts. Failure is likely to occur if you are not careful, and the roller needle of the ejector pin seat is bitten, and the troubleshooting method.
