The hot-sticking type processing method of tyre side rubber sheet
Technical field
The invention belongs to a kind of method of tyre side rubber sheet of processing automobile tire.
Background technology
In the full steel wire heavy load radial tire production procedure, extrude the important task that workshop section bears supply tyre surface, sidewall, triangle, four kinds of semifinished part of pad glue.In the prior art; processing technology for the sidewall is: after the extrusion calendaring production line is extruded the applying film (being to produce on other production line); on unwinding device; then the applying film is pulled out from unwinding device; adopt pressing rod 4 and the mode of carrying raceway 1 pressing at the A station of producing train line and B station; the applying film plaster of the corresponding specification of multiple working procedure output is lumped together,, improve the quality of product to play the effect of protection sidewall composite surface.The shortcoming of this mode is: since the cold and hot sizing material applying of adopting, poor adhesion, and the plastics waste amount that the film production process is played preservation is bigger; Simultaneous process for pressing instability, frequent replacing film roll is easy to generate bubble, and joint or the like problem has strengthened the amount of returning of parts, has reduced production efficiency.Among Fig. 12 is the sidewall, is the rubber components that tire is used in manufacture process.
Summary of the invention
The objective of the invention is to seek a kind of hot-sticking type processing method of tyre side rubber sheet,, reduce energy resource consumption, manpower consumption and the consumption of materials simultaneously to avoid the bad problem of cold and hot applying.
According to design provided by the present invention, in the spout of extrusion device, add sizing material, through forming the applying film behind the extrusion device, a guider is set on the direction of advance of applying film then, the applying film is fitted with the sidewall that is positioned at above the belt through entering behind the guider on the belt of carrying raceway.
Advantage of the present invention is: because applying film parts are immediately and extrude, the cohesive of sizing material is better, makes and has avoided the process for pressing instability when meeting, frequent replacing film roll is easy to generate bubble, joint or the like problem, improve production efficiency, reduced the defective semi-finished product amount of returning.

The specific embodiment
The sizing material 11 that in the spout 10 of extrusion device 9, adds traditional production doughnut tyre side rubber sheet commonly used, form applying film 8 through extrusion device 9 backs, a guider 7 is set on the direction of advance of applying film 8 then, applying film 8 is fitted with the sidewall 5 that is positioned at above the belt through entering behind the guider 7 on the belt of carrying raceway 6.Guider 7 can be a guide roller.
The present invention utilizes in conjunction with the existing processes condition
Extruder is directly extruded film, and online applying.So not only solved the bad problem of cold and hot applying, also simultaneously energy resource consumption, manpower consumption, the consumption of materials of production aspect has been played a good role.
The present invention makes full use of
In the small-sized calender device
Small-sized extrusion device is combined on the semifinished part in conjunction with the online film heat posted of extruding of corresponding circular type rubber die plate.
The present invention under the constant situation of original process conditions,
Small-sized extrusion device adds a film guider, makes film accurately to be fitted on the seat.During work, when two complex extruders are extruded composite component
Small-sized extrusion device is extruded the film of corresponding specification, directly fits together on production line under the effect of guider.
