Cutting machine for cloth sewing

Abstract

The invention relates to the technical field of cloth cutting, and discloses a cutting machine for cloth sewing. The cutting machine comprises a machine body outer frame; a conveying belt is movably driven in the middle of the machine body outer frame; and conveying wheels are movably connected to two ends of the conveying belt. According to the invention, multiple layers of cloth are placed on the upper surface of the conveying belt, the weight of the cloth enables a rotating shaft to drive a movable column to compress a pressure current increasing spring to move downwards, meanwhile, a sliding pointer is driven to slide downwards on a sliding rheostat to reduce the resistance in a circuit, and therefore the current passing through a centrifugal fan is increased to increase the running vacuum suction of the centrifugal fan; linear adjustment is achieved through the characteristic of linear change of gravity, elastic force and resistance along with the length; when cutting is conductedand a tool bit pressurizes the cloth, the centrifugal fan additionally adds vacuum adsorption force to prevent cloth deviation caused by sudden increase of cutting resistance; and the adsorption force is dynamically adjusted according to a working state, and resources are reasonably utilized, so that the problem of energy waste or infirm adsorption caused by fixed vacuum adsorption force is solved.

Description

technical field [0001] The invention relates to the technical field of cloth cutting, in particular to a cutting machine for cloth sewing. Background technique [0002] The cutting machine for fabric sewing is a kind of equipment that uses numerical control to control the cutting head to cut the cloth on the conveyor belt. The cloth is automatically loaded and unloaded by the conveyor belt. Cuts the cloth according to the specified format. [0003] There are still some problems in the existing cloth cutting machine: First, the vacuum suction force of the centrifugal fan to the vacuum adsorption chamber is fixed. For a few layers of cloth, the vacuum suction is too large to cause energy waste, and for multi-layer cloth. Vacuum suction may be insufficient The upper layer of fabric is not firmly adsorbed; secondly, when the cutter head is cutting multi-layer fabrics, especially when the cutting path is arc-shaped, the action of the cutter head will easily drive the upper layer...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing cloth sewing cutting machine proposed in the background technology, the present invention provides a cloth sewing cutting machine, which can provide corresponding vacuum suction according to the amount of cloth, and prevent the upper layer of cloth from being compacted. The advantage of large cutting error caused by the vibration and movement of the cutter head solves the technical problems raised in the above background technology
