Method for producing cold press molding lathe compound belt blank of IW woven steel cord rubber belt

Abstract

The invention relates to a method for producing a cold press molding lathe compound belt blank of an IW woven steel cord rubber belt. The method is characterized in that: the method comprises the following process steps that: rubber compounds of core rubber and covering rubber are extruded out by a cold feed wide rubber sheet extruder respectively and then prepared into a rubber sheet of the core rubber and a rubber sheet of the covering rubber respectively by a two-roll calender calendaring linkage production line, and the rubber sheet of the core rubber and the rubber sheet of the covering rubber are isolated by cloth liner and rolled without tension respectively; the rubber sheet of the core rubber and the rubber sheet of the covering rubber are combined by two press rolls of the extrusion calendaring production line to prepare an upper compound rubber sheet roll and a lower compound rubber sheet roll respectively; and an IW woven steel cord is arranged between the upper compound rubber sheet and the lower compound rubber sheet, and compounded into a whole by a cold press molding lathe cold press flat panel, and edge cutting is carried out according to process requirements to obtain the belt blank. The method fully utilizes the prior equipment resources, has flexible production, and improves working efficiency and utilization rate of equipment; moreover, the method also has the advantages of low air porosity of the rubber sheets, even tension of the whole rubber belt, good penetrability of a rubber material, easy control of the thickness of the rubber sheets, stable spacing among longitudinal woven steel cords, and straight and square-shaped zonal steel cords.

Description

technical field [0001] The invention relates to a production method of an IW steel curtain mesh tape cold-press forming vehicle composite strip blank, in particular to a process flow of an IW steel curtain mesh tape cold-press forming vehicle composite strip blank. Background technique [0002] The IW steel curtain mesh is a unique steel cord woven mesh specially designed for high-performance tapes through a special design of warp-direction transparent cords and weft-direction high-stretch cords. This special weaving structure can make warp The directional cord is not easy to deform under any circumstances, so that the steel wire can exert its highest strength without being easily damaged. It has superior performance in impact resistance, high temperature resistance, tear resistance and deformation resistance, and has a very large grooving It is durable and suitable for excellent performance of drive pulleys with smaller diameters. IW steel curtain tape is gradually applied...

AI Technical Summary

Problems solved by technology

[0004] 1. The width of the tape is limited by the size of the working roller of the calender

[0005] 2. For general enterprises, the equipment layout and spatial position of the traditional fabric core tape production line are relatively fixed. Although the main equipment does not require additional investment, due to the limited space position, the calendering, unwinding and rolling of the IW steel curtain mesh is limited. It is difficult to renovate the extraction device, etc.

[0006] 3. It is difficult to control the adhesive rate and thickness during calendering

After repeated back and forth calendering and bonding, the difference between the middle thickness of the cross-section of the product and the thickness of the two sides increases; When the curtain net is unrolled, the tension should not be too large, forcing the spacing of the longitudinal steel cords to change, and it is also difficult to keep the weft cords straight and square
