Extremely wide type breadth shortening forming cutting machine

Abstract

The invention relates to an extremely wide type breadth shortening forming cutting machine used for the length fixing and breadth fixing of formed high-density fabric of terylene and polypropylene fiber, and providing qualified cloth used for industrial filtration for a belt filter. According to the invention, the overall structure is composed of a shaft bracket, a length fixing and breadth fixing cutter, a winding device, and the like; a yardage roll is unwound on the shaft bracket freely and then enters into a length fixing and breadth fixing cutting area; a variable frequency motor actively drives to-be-cut filter cloth in the breadth fixing cutting area, and a pressure cutting wheel pneumatically controlled by hot melting of 2-3 ultrasonic waves is fixed on a horizontal guide rail according to the size of the breadth for breadth fixing cutting; a winding mechanism is controlled by the variable frequency motor, when the wound yardage roll reaches a set length, the cut filtering cloth stops operation, and is controlled to operate by a heating resistor hot melting cutter along the horizontal guide rail through the variable frequency motor, so as to conduct fixed length cutting.

Description

technical field [0001] The invention relates to an extra-wide narrowing and setting shearing machine, which is used for the fixed length and fixed width of polyester and polypropylene high-density fabrics after setting, and provides qualified industrial filter cloth for belt filters. Background technique [0002] The extra-wide shrinking setting machine is a machine designed by us in the early stage. Its principle is to heat polyester and polypropylene high-density fabrics to the required temperature under a certain tension, and heat them for a certain period of time at this temperature, and then cool them down rapidly. , so that the high-density fabric shrinks to meet the technical requirements of the filter cloth of the filter. The heat-set polyester and polypropylene high-density fabrics must be cut into filter cloth products of a certain length and width, that is, fixed-length and fixed-width products. If manual cutting is used, the workload is large and the efficiency i...

AI Technical Summary

Problems solved by technology

The heat-set polyester and polypropylene high-density fabrics must be cut into filter cloth products of a certain length and width, that is, fixed-length and fixed-width products. If manual cutting is used, the workload is large and the efficiency is low. However, the shaping shears currently on the market There are few types of cutting machines, the technical conditions are not yet mature, and they are not matched with the shaping machine we designed. Therefore, in order to meet the needs of customers, we cooperated with a textile machinery factory in Yancheng to design and develop a shrinking shaping shearing machine. Therefore, The ultra-wide narrowing and shaping shearing machine designed in this paper is a supporting product of the extra-wide narrowing and shaping machine. It is used for the fixed length and fixed width of polyester and polypropylene high-density fabrics after shaping, and provides qualified industrial equipment for belt filters. filter cloth
