Novel white sidewall extrusion device

Abstract

The invention discloses a novel white sidewall extrusion device, comprising a phi 150 screw rod, a phi 200 screw rod, a phi 90 screw rod, a phi 120 screw rod, a novel white sidewall extruded line handpiece, extruded white sidewall rubber, novel white sidewall extruded line auxiliary lines, a covering rubber piece, a phi 90 screw rod extruder, a small double-roller extruder and a transmission band; the phi 150 screw rod, the phi 200 screw rod, the phi 90 screw rod and the phi 120 screw rod are sequentially and smoothly connected to the novel white sidewall extruded line handpiece from bottom to top by a pipeline, the novel white sidewall extruded line auxiliary lines are paved on both sides of the transmission band, the extruded white sidewall rubber is paved in a central position of the transmission band, and the covering rubber piece is mounted on a rotary shaft of the small double-roller extruder. The required novel white sidewall extruded line is produced by exclusively designing a semisteel white sidewall tire, the sidewall rubber, seam allowance rubber, isolation rubber and white rubber are respectively extruded by phi 150 / phi 200 / phi 90 / phi 120 four-composite extruded linked lines, the composite extruded lines can realize two symmetric sidewalls, one white sidewall and one black sidewall are extruded simultaneously, and the sidewall at one white rubber side is additionally adhered to covering rubber of a protective layer.

Description

technical field [0001] The invention relates to the field of tire production, in particular to a novel white sidewall extruding device. Background technique [0002] At present, the production of white sidewall tires in the semi-steel tire industry is generally completed through the Ф150 / Ф200 / Ф120 three-composite extrusion linkage line. The white glue is in direct contact with the sidewall rubber. The white glue is easy to pollute the sidewall rubber and affect the flexibility of the sidewall. It is not conducive to the stability of the quality of white sidewall tires. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a novel white sidewall extruding device. To achieve the above object, the present invention adopts the following technical solutions: [0004] A new type of white sidewall extrusion device, including Ф150 screw, Ф200 screw, Ф90 screw, Ф120 screw, new white sidewall extrusion...
