Method and device for laminating edge margin rubber sheets at reverse side of air retaining liner rubber sheet

Abstract

The invention relates to a method and a device for laminating edge margin rubber sheets at the reverse side of an air retaining liner rubber sheet. The edge margin rubber sheets are not required to beturned over, and because a laminating method that both sides of the air retaining liner rubber sheet are turned up for certain angels is adopted, not only the reverse-side laminating efficiency is improved, but also the laminating size of the two kinds of rubber sheets can be selectively adjusted; and the quick switching of the face side laminating and the reverse side laminating can be synchronously realized. The concrete method comprises the following steps: the air retaining liner rubber sheet and the edge margin rubber sheets are respectively conveyed along the same laminating conveyer belt, and the central lines of the air retaining liner rubber sheet and the edge margin rubber sheets are mutually parallel; before the two kinds of rubber sheets are mutually overlapped, the air retaining liner rubber sheet is guide to a turned-edge guide mechanism, and the two side edges of the air retaining liner rubber sheet are synchronously and obliquely turned upward for certain angels; the edge margin rubber sheets at the left side and the right side are synchronously conveyed to the lower parts of the two side edges of the air retaining liner rubber sheet through a horizontal guide mechanism to realize the overlapping of the two kinds of rubber sheets; and the two kinds of overlapped rubber sheets are conveyed forwards to realize the reverse-side laminating through a rolling mechanism.

Description

technical field [0001] The invention relates to a method and a device for laminating slit films on the reverse side of an inner liner extrusion production line, belonging to the field of tire manufacturing. Background technique [0002] At present, in the production process of semi-steel tires, the inner liner extrusion production line is required to produce the inner liner film, rim film and shoulder pad rubber required for the inner liner through the relevant extrusion, lamination and calendering processes The film is compounded to achieve the airtightness and density requirements of the connection between the various parts of the inner liner. Depending on the process requirements and the differences in tire types, it is usually necessary to attach the spigot film to the front or back of the inner liner film. [0003] Existing liner layer extrusion production lines are usually equipped with reversing conveying devices for laminating slit films in forward and reverse direc...

AI Technical Summary

Problems solved by technology

Therefore, the existing reversing conveying device for flipping the slit film needs to occupy a large installation and operation space, which not only increases the production cost of the production line equipment, but also has low production efficiency and increased energy consumption.
