Plastic bag making machines and their processing objects, specifically plastic films, have a mutually adaptive characteristic, which means that a mechanical equipment can only process plastic films within a certain range of properties. Based on understanding the properties of plastic films, we start from the three essential factors of bag making, namely pressure, temperature, and pressing time. When making bags (while ensuring the pressing strength, relatively speaking), the pressing pressure should be higher, The hot pressing temperature should be low and the hot pressing time should be long. After this treatment, the hot pressing seal of the composite bag will be beautiful, beautiful, and straight.

Solution: (1) If the adjustment method and working state of the photoelectric eye are not selected correctly, adjust it correctly according to the instructions. (2) The deviation between the pre adjusted film feeding length (when adjusting the blank bag) and the actual bag size is too large, and the line length or pressure should be reset or the device adjusted. (3) If the film resistance is too high or the product quality of the previous process is poor, the material should be inspected and replaced.

Solution: (1) Poor adjustment of photoelectric eye sensitivity or incorrect polarity selection. (2) The photoelectric switch should be replaced due to ground leakage or short circuit between terminals. (3) If the feeding speed is lower than the feeding speed, it is necessary to loosen the pressure film strips, check the performance of the feeding part, and troubleshoot.

Injection molding is a method of industrial product production molding. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding, compression molding, and die-casting. Injection molding machine (abbreviated as injection molding machine or injection molding machine) is the main molding equipment that uses plastic molds to make various shapes of plastic products from thermoplastic or thermosetting materials. Injection molding is achieved through injection molding machines and molds.
