Polyurethane tire production line

Abstract

The invention relates to the field of polyurethane foaming production, and discloses a polyurethane tire production line, which comprises a circularly arranged rotary turntable, an injection machine head is fixed on a base through a transmission device, the injection machine head is connected with a feed liquid storage tank through a feeding mechanism, and a circular track is arranged on the outer side of the rotary turntable. The machine base moves along the circular track through the walking device. The feed liquid storage tank is located at the circle center of the circular track, and the feeding mechanism is connected with the feed liquid storage tank through a sliding ring. A component stock solution and a component stock solution B are conveyed into the material injection machine head through the feeding mechanism for mixed material injection, and after the material injection machine head completes material injection, the material injection machine head moves to the next rotary type rotary table along the circular track through the walking device to continue material injection operation. The whole production line is circularly arranged, continuous movement on each rotary table station is achieved, the walking device can be automatically controlled to move on the circular track, automatic movement of the injection machine head is achieved, manual movement operation is omitted, and the overall production efficiency is improved.

Description

technical field [0001] The invention relates to the field of polyurethane foam production, in particular to a polyurethane tire production line. Background technique [0002] Polyurethane tires are wheels made of foamed plastics by injection molding. They have the characteristics of dimensional stability, low shrinkage, stable chemical composition, anti-corrosion, anti-aging, and good wear resistance. Due to the existence of internal air bubbles, the foam wheel made of foamed plastic has the advantages of light weight, material saving, and can absorb shock loads. Therefore, the foam wheel has a wide range of applications, especially in various transportation equipment and other fields. special application value. [0003] Polyurethane foaming machine is a special equipment for polyurethane infusion foaming. It is often used in the production of foaming wheels. Generally, polyether polyol and polyisocyanate are used as the two components of A and B. After accurate proportioni...

AI Technical Summary

Problems solved by technology

[0005] The present invention intends to provide a polyurethane tire production line to solve the problem of low production efficiency due to the discontinuous movement of the injection head in the existing semicircular production line and the need to manually control the movement of the injection head and the injection of the material liquid.
