Description
Aluminum-plastic composite pipe production line
I. Overview
The production line is used to produce aluminum-plastic composite pipes. The aluminum pipes are formed in one step by ultrasonic welding and co-extrusion. The produced aluminum-plastic composite pipes are widely used in cold and hot tap water, various liquids of acid and alkali salts, gas, oxygen, compressed air, etc. Pipelines for various gases.
The inner layer of Huaming Plastic Machinery is PE, the middle layer is aluminum tape, the outer layer is PE, and the middle is adhesive.
Features of the production line
1. High degree of automation, PLC control throughout the line to ensure that the process parameters are accurate and in place.
2. The operation intensity is low and the operation is simple.
3. Each device is based on the material characteristics, production characteristics, special design and special processing of the aluminum-plastic composite pipe to ensure reliable and perfect performance of the whole machine.
Second, the process description
The main line is a high-precision aluminum tube forming line. When the aluminum tape roll is unwound by a passive unwinder and the straight aluminum tape is fed into the pre-formed roller track through various positioning mechanisms, the aluminum tape is rolled into an aluminum tube The prototype is then fed into the forming section. The aluminum strip and aluminum tube that come out of the forming section have only general accuracy. It must be reshaped and positioned in the sizing section to meet the accuracy requirements. The superposed part of the aluminum tube is ultrasonically welded by an ultrasonic continuous welding machine to form a closed high-strength aluminum tube.
The aluminum pipe welding area of the production line is the branch junction. The other two branches are the inner tube and the inner bonding layer: the outer tube and the outer bonding layer. After feeding, hot-melting, extruding, and entering the confluent template, they are distributed by the confluent template and enter the inner tube co-extrusion and outer tube co-extrusion die. Compressed air is always injected into the inner tube of the composite tube to detect the pressure-holding performance of the pipeline, and then it is shaped by the cold bath and automatically dried. After measuring the length, it enters the printing area and uses an automatic inkjet printer to change the company name, tube size, length, etc. Printed on the tube. After being pulled, the printed tube is wound up and wrapped by an automatic double-disc winder. After being wrapped, the rolled tube can be packaged and shipped out.
