Problems solved by technology

[0004] The purpose of the present invention is to provide a tread mouth plate device with adjustable thickness, which solves the problem that my country is a big country in tire production and use, but the extrusion process of domestic tire production has always used a tread mouth plate with an adjustable thickness. , which seriously restricts the development of my country's manufacturing industry. Different patterns of tires of each specification are used for different tread plates. As the raw materials and process parameters of compound rubber change, the thickness and dimension of the tread components also change accordingly. The original thickness The non-adjustable tread mouth plate cannot meet the requirements, and only a few or more than a dozen tread mouth plates can be made according to the same specification and the same pattern to meet the requirements. Due to changes in raw materials and process parameters of the compounded rubber, continuous production cannot be performed, resulting in rubber The amount of material return is large, and the number of tread mouth plates is large
Moreover, the mouth plate is a vulnerable and worn part, which has high replacement costs, cumbersome operation, and low production efficiency.

Abstract

The invention discloses a thickness-adjustable tire face square plate device which comprises an extruding machine, a square box, square plates and a motor supporting structure. A screw is arranged inthe extruding machine. A runner is arranged on the right side of the screw. The square box is installed on the right side of the runner. According to the thickness-adjustable tire face square plate device, the shape discharging distance can be adjusted according to the requirement, therefore compared with the prior art, the number of square plates for standby application can be reduced substantially, meanwhile, the number of replacing the square plates can be reduced, the rubber return amount is reduced, the production cost is reduced, operation is easy, the production efficiency is improved,by means of the arranged square plates, the thickness of the tire face can be adjusted, the thickness-adjustable tire face square plates are wide in application range and can be matched with the corresponding runner and the pre square plates to be applied to cold feeding, hot feeding and various dowel extruding machines, and meanwhile the device is applicable to a single or composite extruding machine.

Description

technical field [0001] The invention relates to the technical field of tire production devices in tire factories, in particular to a thickness-adjustable tread die plate device. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. The tread is an important component of the tire. The tread extrusion pressu...
