Single-drum forming method of wrapped V-belt

Abstract

The invention belongs to the technical field of formation of wrapped V-belts, and discloses a single-drum forming method of a wrapped V-belt. According to the inner perimeter size of a target wrapped V-belt, an expansion drum with the proper size is selected and mounted; a protective gum cover coats the expansion drum; the outer perimeter of the protective gum cover is equal to the inner perimeter of the target wrapped V-belt; the expansion drum is expanded to the protective gum cover; the periphery of the protective gum cover is coated with zinc stearate; then, primer and buffer glue are applied in sequence; an automatic cord winding control device is started; the tension is set according to the belt type and the cord specification; a cord is wound, then a top glue is applied and compacted; an automatic cutting device is started to cut off the corresponding width according to the belt type; the expansion drum is shrunk; a belt blank is removed; the rectangular belt blank is cut to a trapezoidal belt blank accordant with the weight requirement on a chamfering machine; and the trapezoidal belt blank is fed to a wrapping machine for wrapping, and is vulcanized to obtain the target wrapped V-belt. The single-drum forming method of the wrapped V-belt has the advantages of more once forming number, high efficiency, accurate length control and more stable quality.

Description

technical field [0001] The invention belongs to the technical field of cloth-wrapped V-belt molding, and in particular relates to a single-drum molding method of cloth-wrapped V-belts. Background technique [0002] The current forming process of wrapped V-belt is double-drum forming. According to the process requirements, the length is measured on the double-drum winding machine, and the cord is wound on the corresponding active and stretching groove rollers, and the buffer glue is attached and pressed according to the structural order. Solid, single-knife or multi-knife cutting into tape core (wire billet), the trapezoidal rubber strip extruded through the extruder or calender and the tape core are bonded and compacted together on the laminating machine, and sent to the wrapping cloth Cloth on board. The double-drum forming method has the following main problems: it cannot be loaded with a fixed tension when the wire rope is wound, and the length of the inner and outer bel...

AI Technical Summary

Problems solved by technology

The double-drum forming method has the following main problems: it cannot be loaded with a fixed tension when the wire rope is wound, and the length of the inner and outer belt cores of the double-groove rollers may be uneven in length; due to the influence of temperature and tension when the rubber strip is extruded, the weight Unstable, the weight of the blank will be unstable after the belt core and the rubber strip are bonded; the product is elongated and the length and dimension are unstable
