Transition layer production line and rubber sheet attaching method

Abstract

The invention belongs to the field of tire part production, and particularly relates to a transition layer production line and a rubber sheet attaching method. The transition layer production line andthe rubber sheet attaching method are applied to an online attaching process of a lining layer engineering steel wire wrapping protection rubber sheet. The transition layer production line comprisesan extruder, wherein the extruder is used for extrusion, a calender is used for extrusion molding, and an exhaust line is pressed under the pressing of an exhaust line device; and the transition layerproduction line is characterized in that a tire protection rubber sheet attaching device is arranged on a transition layer main machine receiving conveying belt behind the exhaust line device, and the tire protection rubber sheet attaching device carries out positioning on a transition layer and attaches a rubber sheet to the transition layer. The problem that bubbles are generated due to the fact that rubber sheet sizing materials are prone to accumulate when the protection rubber sheet is attached to the end part of a protection steel wire and punctures the lining layer is solved.

Description

technical field [0001] The invention relates to the field of tire component production, in particular to a transition layer production line and a film lamination method, which are applied to the on-line lamination process of inner liner engineering steel wire-wrapped protective films. Background technique [0002] According to the traditional design concept, the edge protection film is added in the carcass production process. After long-term quality verification, the market return of steel wire end bridge defects is gradually decreasing, but the proportion is still not to be underestimated. However, in the actual bonding process and use of the protective film at the end of the steel wire, due to the narrow width and thin thickness of the film and the large number of laminated films for the carcass steel wire, quality problems such as pleating and out-of-fitting of the protective film often occur. Once the above abnormalities occur, the protective film not only does not play ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a transition layer production line and a film bonding method to solve the problem that the protective film is pasted and pierced at the end of the protective steel wire to pierce the inner lining layer, which may easily cause the accumulation of film and rubber to generate air bubbles
