Five layer co extrusion film blowing machine

Five layer co extrusion film blowing machine Product introduction

Five layer co extrusion film blowing machine adopts easy batch and ISMD high torque servo direct drive motor.

The easy-batch mixer can mix all kinds of raw materials according to the requirement of weight ratio in the extrusion process, and control the screw speed and traction roller speed of the extruder, so as to control the extrusion volume and weight per meter.

The easy-batch system can be controlled automatically by remote terminal operation. The display can display all program data, while the operator can control the entire device or each individual part in a specific area of the touch screen on the main controller panel. ISMD series high torque servo direct drive motor adopts direct drive motor without gearbox system.

Compared with the traditional asynchronous motor or dc motor with transmission system, its advantages are to replace the reducer, reduce noise, full speed range, wide load range to maintain high efficiency; High power factor; Improve dynamic response; Compact structure to reduce equipment volume and save cover space; Improve control precision, improve product quality; Increase MTBF(mean uptime) index; Significantly reduce maintenance workload; Convenient screw disassembly.

Five layer co extrusion film blowing machine Advantages 

1. Upper traction design features

This is a technical improvement on topspin instead of die head rotation. The traction roller and herringbone splint rotate 180° before and after, and the film ACTS as a radius to eliminate the phenomenon of "critical strengthening" caused by bubble thickness. The die head is always at rest and the film thickness is more uniform.

2. Automatic cooling air ring

The air ring is divided into Chambers. Each chamber of the valve is controlled by a stepping motor. It connects to monitoring software. The data can be adjusted according to the thickness measurement system. When the thickness is greater than the set thickness, the electrical machine reduces the flow of air into the corresponding parts to reduce the thickness of the film. In the same sense, when the thickness is less than the set thickness, the electricity will strengthen the airflow into the corresponding part to increase the thickness of the film.

3. Batch and weight loss mixed feeding system

Integrated absorption, weighing and mixed control of extrusion output can realize the control and statistics of material consumption.

Operating principle: the operator sets the formula on the touch screen, and the system automatically absorbs the material. The raw material is loaded into the screw according to the requirements of sufficient stirring and extrusion.
