Abstract

The invention relates to the field of tire production, in particular to a high polymer material balance car tire manufacturing process and equipment. In order to solve the technical problems that the processing steps of high polymer material tire processing are tedious, and obvious splicing boundaries exist after extrusion molding after the head and tail ends of a tire root and a tire crown are directly spliced into a ring. The high polymer material balance car tire equipment comprises a conveyor, a cutting unit and the like. And the front side of the conveyor is connected with a cutting unit. According to the invention, the macromolecular rubber material which is just extruded from the extruder is still kept in a softened state, and the end-to-end junction of the annular macromolecular rubber material obtained by pre-coiling does not have obvious junction traces, so that the treatment steps of extrusion into strips, fixed-length cutting and ring splicing are combined into one treatment step; and then pressing treatment and molten high polymer material filling treatment are performed, and finally, after curing molding treatment is completed, a final tire product is obtained.

Description

technical field [0001] The invention relates to the field of tire production, in particular to a production process and equipment for a balance car tire made of polymer materials. Background technique [0002] A tire made of polymer materials used for balance cars. The inner tube is a non-inflatable run-flat tire made of a variety of polymer materials. The tire crown, and several tire columns used to connect the tire root and the crown. [0003] In the process of producing the polymer material tires used for balance cars, it is necessary to put two sets of polymer materials forming the tire root and tire crown into two extruders respectively, and the two sets of polymer materials are extruded by the extruders. The material is extruded into two long columnar polymer rubber materials respectively, and the two long columnar polymer rubber materials are respectively cut according to the circumference of the tire root and the tire crown, and then the cut two The polymer rubber ...
