Abstract

The invention discloses a tire tread tubing method. The tire tread tubing method comprises following steps: warming, tubing, laminating, weighing, cooling, automatic printing, polishing, automatic length fixing, cutting, examining, and storing. Before tire tread tubing, an extrusion machine head, a machine body, and a mouth-shaped plate are subjected to preheating; rubber supplying temperature is controlled to be 80 to 90 DEG C, the temperature of the extrusion machine head ranges from 75 to 85 DEG C, the temperature of a machine cylinder ranges from 35 to 45 DEG C, the temperature of the mouth-shaped plate ranges from 80 to 90 DEG C, and rubber discharging temperature is lower than 120 DEG C. No bubble is observed in extruded tire treads; tire tread section size and quality accord with requirements; and edge broken is not caused.

Description

[0001] technical field [0002] The invention belongs to the technical field of tire molding, and in particular relates to a tire tread extruding process. [0003] Background technique [0004] Extrusion process of tire tread Extrusion equipment is generally divided into hot-feed extrusion method and cold-feed extrusion method, but there are generally air holes inside the extruded tread, the size and quality of the tread section do not meet the requirements, and it is easy to break Defects such as rotten edges. [0005] Contents of the invention [0006] The object of the present invention is to provide a tire tread extruding process. There is no air hole in the extruded tire tread, the size and quality of the tread section meet the requirements, and the phenomenon of broken edges and rotten edges does not occur. [0007] The tire tread extruding process provided by the present invention includes the following steps: heating → extruding → bonding → weighing → cooling → ...
