ब्लिस्टर थर्मोफॉर्मिंग पैकेजिंग मशीन is divided into many specifications according to the width of the film that can be processed, but no matter which specification, the working principle is basically the same.
Automatic thermoforming packaging machine is generally composed of the following parts: film conveying system, upper and lower film guide section, pre-heating zone and thermoforming zone of the bottom film, as well as filling zone, heat sealing zone, slitting zone and control system, etc. Etc composition. The whole machine adopts a modular structure design, and various devices can be added or deleted according to user needs, so as to change the function.
Because the fully automatic thermoforming packaging machine uses roll film forming packaging, it requires a film traction and conveying device. During the work, the bottom film will be clamped and pulled during the whole process from preheating to sealing and slitting. The power is generally from the conveyor chains arranged on the longitudinal sides of the machine. Each section of the chain is equipped with a clip, and the conveying chain sends the bottom film from the machine to the terminal in a continuous step-in type.
The chain of the standard model is driven by a two-speed three-phase motor. When feeding, it adopts high-speed directly. It automatically switches to low-speed operation before each step is stopped, so that it can accurately stop at the end position of each step.
