Belt ply laminating drum mechanism with two supported sides

Abstract

The invention relates to a belt ply laminating drum mechanism with two supported sides. The belt ply laminating drum mechanism comprises a main shaft, a left guide disc, a left drum plate, a middle drum plate, a right drum plate and a right guide disc, wherein the left guide disc, the left drum plate, the middle drum plate, the right drum plate and the right guide disc are sequentially arranged onthe outer side of the main shaft from left to right; the left drum plate is in radial sliding connection with the left guide disc through a left sliding block; the right drum plate is in radial sliding connection with the right guide disc through a right sliding block; the middle drum plate is fixedly connected with a middle sliding block; the middle sliding block comprises an inclined surface and is in sliding connection with a middle sliding seat through the inclined surface; a push rod is arranged inside the main shaft; and the push rod extends out of the middle position of the main shaftand is fixedly connected with the middle sliding seat. The problem that two ends of a rubber belt ply droop when the rubber belt ply is laminated in the prior art is solved, the laminating effect is improved, and meanwhile, the phenomenon that two ends of the rubber laminating layer are folded in the reverse packaging process is avoided.

Description

technical field [0001] The invention belongs to the technical field of rubber tire building machinery, in particular to a belt laminating drum mechanism supported on both sides. Background technique [0002] With the continuous growth of domestic automobile sales, the tire manufacturing industry is also growing rapidly. As a standard component of tire manufacturing equipment, tire belt drums play an important role in tire molding. The tire belt drum is used as the equipment for laminating the rubber layer of the tire. When the tread of some specifications of the tire is wider than the belt layer, there is no support on the two sides of the wider side during the lamination process, which will affect the effect of the rubber lamination layer. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art, to provide a belt laminating drum mechanism supported on both sides, which solves the problem that the ...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art, to provide a belt laminating drum mechanism supported on both sides, which solves the problem that the two ends of the rubber belt appear when laminating the rubber belt in the prior art. There is no sagging problem, which improves the bonding effect and avoids the folding phenomenon at both ends of the rubber bonding layer during the turn-up process
