Rubber sheet winding and rolling mechanism of tire tread winding machine

Abstract

The invention provides a rubber sheet winding and rolling mechanism of a tire tread winding machine. The rubber sheet winding and rolling mechanism comprises a first frame plate, a second frame plate, a main compression roller, a front compression roller and a rear compression roller, wherein the first frame plate and the second frame plate are arranged in parallel; and the main compression roller is arranged between the first frame plate and the second frame plate. The front compression roller and the rear compression roller move oppositely to roll rubber sheets and convey the rubber sheets to the main compression roller. Grooves are distributed in the front compression roller. Thorns matched with the grooves in the front compression roller are distributed on the rear compression roller. The rubber sheet winding and rolling mechanism of the tire tread winding machine is simple in structure. Pressing is performed while rubberizing, pressing density is high, and tire product quality can be guaranteed after renovation.

Description

technical field [0001] The invention relates to the technical field of tread automatic winding rubber material in the retreading production process of engineering machinery tires, in particular to a film winding and rolling mechanism of a tread winding machine. Background technique [0002] In recent years, construction machinery tires have grown with the substantial growth in demand for loaders, forklifts, and bulldozers, and have become the fastest-growing, hottest, and most potential market in the tire market. [0003] The automatic tread winding machine is used to wind the tread rubber when retreading engineering tires. After the engineering tires are polished and enter the mold for vulcanization, raw rubber needs to be re-pasted on the polished carcass. The process is extruded by cold feed. The molding machine extrudes rubber strips with a certain thickness and width, and transports them to the winding machine through the feeding rack and conveyor belt. The operator sel...
