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
The pressure produced by the roller on the middle part of the skeleton material and the extrusion and shearing of the rubber material gradually increase. In addition, the tension of the steel curtain mesh should not be too large when unwinding, forcing the longitudinal steel cord spacing to change. Difficulty keeping weft cords straight and square

Embodiment 1

[0028] Embodiment 1: The present invention mainly adopts the production method of compounding blanks in the extrusion and calendering production line of cold-feed wide-width film. The strip blank is completed on the film extrusion and calendering linkage production line. Including the following process steps:

[0029] 1. Core glue and cover glue out

[0030] The mixed rubber of the core rubber and the mixed rubber of the cover rubber are respectively extruded by a cold-feed wide-width film extruder and calendered by a two-roller calender to make a core rubber film and a cover rubber film. The core rubber film and the cover rubber film are separated by pad cloth and taken up without tension. The roller deflection compensation of the two-roller calender adopts the cross-axis adjustment to eliminate the waist drum shape of the film section, which is thick in the middle and thin on both sides.

Abstract

The invention relates to a method for producing a compound belt blank by a cold feed wide rubber sheet extrusion calendaring linkage production line. The method is characterized in that: the method comprises the following process steps that: rubber compounds of core rubber and covering rubber are prepared into a rubber sheet of the core rubber and a rubber sheet of the covering rubber respectively by a cold feed rubber sheet extrusion calendaring production line; 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 cold feed wide rubber sheet extrusion calendaring production line to prepare an upper compound rubber sheet roll and a lower compound rubber sheet roll respectively; an IW woven steel cord is placed between the upper compound rubber sheet and the lower compound rubber sheet, and combined with the upper compound rubber sheet and the lower compound rubber sheet into a whole roll by the press rolls of the cold feed wide rubber sheet extrusion calendaring production line; and the cloth liner in the combined whole roll is rolled, then edge-cut as required is carried out to obtain the belt blank, and the cloth liner is inserted the belt blank for standby. The rubber sheet has the advantages of high quality, smooth surface, low air porosity, high compactness, easy control of the thickness of the rubber sheet, stable spacing among the longitudinal woven steel cords, and straight and square-shaped zonal steel cords.

Description

technical field [0001] The present invention relates to a production method of a compound strip blank of a cold-feed wide-width film extrusion-calendar linkage production line, especially a process for a composite strip blank of a cold-feed wide-width film extrusion-calendar linkage production line processed by IW steel curtain tape process. 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 dr...
