Let Me Introduce The Overall Structure Of The Plastic Express Bag Manufacturing Machine.

The overall structure of the plastic express bag manufacturing machinery is designed around automated production processes, encompassing five core modules: raw material processing, film forming, printing, spraying and bag making. Each module achieves efficient collaboration through precision mechanical coupling and intelligent control. Here's a detailed look at its overall structure:

I. Raw Material Processing Module

* Storage Device: Storage of plastic raw materials (e.g. recycled, raw and semi-raw materials) and their transport by photoelectric control to a blow-dryer in quantitative quantities to ensure a steady supply of raw materials.

* Mixing Machine: Stir and mix ingredients in proportion to recipe to provide a uniform raw material base for subsequent blowing film production.

ii. Film Forming Module

* Blown Film Machine: Heating and melting mixed ingredients and blowing them into thin film is a basic step in the production of express bags. During the blown film process of the film, details such as material thickness, size, color and corona treatment must be controlled.

* Cooling Device: Cooling and setting of blowing film to ensure stable film quality.

III. Printing module

:: Printing press: Prints text and patterns on film to improve the recognizability and aesthetic quality of courier bags. In the printing process, it is important to ensure that the pattern is positioned correctly and that colors are bright.

IV. INTRODUCTION Glue Spraying Module

Glue Spraying Machine: Spray on printed film to create openings for later bagging. Precise control of the spray position is the key to ensure that the courier bag is opened accurately.

V. Bag Making Module

Bagging machine: Cut and seal film to create finished courier bags. Bagging machines typically include the following key components:

Heat Sealing Cutter: Controlling temperature, cutting and sealing the film through a temperature controller. Seal width, length and thickness can be adjusted according to production needs.

Step Device: Move the material forward at a set pace to ensure the exact length of the bag.

Frequency conversion speed regulation: drive the heat sealing cutter, achieve precision cutting and sealing.

Bag Consolidation Device: after a certain number of bags have been produced for consolidation, convenient for later packaging and transportation.

Controls: Coordinate all actions to automate production.

VI. INTRODUCTION Auxiliary Module

Photoelectric Tracking Device: using photoelectric sensors to Tracks equidistant color marks, realize automatic positioning control and ensure accurate placement of printed patterns.

Servo motors: Provides accurate power output to ensure coordinated movement of all components.

Framework: Supports and ensures the safety of all components and the overall stability and reliability of the equipment.
