Joint feeding device of inner liner layer and cord fabric layer in radial ply tire building machine

Abstract

The invention relates to a joint feeding device of an inner liner layer and a cord fabric layer in a radial ply tire building machine, comprising a stander, inner liner layer unwinding equipment, an inner liner layer correcting device, an inner liner layer feeding rack, length measurement sensor, a disk cut-off knife, an inner liner layer swing frame, cord fabric layer unwinding equipment, a cord fabric layer unwinding frame, a cord fabric layer feeding rack, a cord fabric layer swing frame and a multiposition cylinder. The joint feeding device of the inner liner layer and the cord fabric layer in the radial ply tire building machine utilizes the multiposition cylinder to move the cord fabric layer feeding rack towards left and right to realize staggered joint of the cord fabric layer; as a device used for moving the cord fabric layer feeding rack is simpler that a device used for moving a joint drum in the prior art, the whole device has simple structure and low power consumption. In addition, the device is also provided with a locating system, so that the positioning accuracy can be guaranteed, and the moving range can be adjusted at will.

Description

technical field [0001] The invention belongs to the technical field of tire machinery, in particular to a device for laminating an inner liner and a carcass layer in a radial tire building machine. Background technique [0002] The inner liner and ply lamination feeding device in the radial tire building machine is one of the important devices used to produce radial tires. The laminating feeding device can cut the inner liner to a fixed length and then attach it to the surface of the laminating drum, and then attach three ply layers to the surface of the inner liner for use in the next process. According to the process requirements, the ply layer sometimes needs to be pasted incorrectly. For example, the first layer of ply layer needs to be attached to the middle part of the surface of the inner liner, the second layer is moved to the left for a certain distance based on the center line, and the third layer is attached to the center line. Move a certain distance to the righ...

AI Technical Summary

Problems solved by technology

At present, the commonly used lining layer and ply lamination feeding device uses the method of moving the lamination drum left and right to realize the wrong lamination. At the same time, the supporting tailstock of the lamination drum also moves accordingly, so not only the structure is complicated, but also At the same time, the moment of inertia of the power machine used to move the bonding drum is also large, and the positioning accuracy is poor, which will undoubtedly affect the quality of the product
