Cloth pressing device and cloth pressing method of automatic cutting bed

Abstract

The invention discloses a cloth pressing device and cloth pressing method of an automatic cutting bed. The cloth pressing device comprises a cloth pressing unit and a pressure control unit. The cloth pressing unit is mounted on a cutting head beam of a cutting table and comprises at least two cylinders and one cloth pressing rod, and the push rod of each cylinder is fixedly connected to the cloth pressing rod; the pressure control unit comprises an electromagnetic valve communicated with the cylinders, a controller connected to the electromagnetic valve and a pressure relief valve connected between the electromagnetic valve and the air source of the cylinders. The cloth pressing method includes setting a pressure limiting value of the pressure relief valve according to the height of the cloth; after cutting, allowing the controller to send a window passing signal to the cutting table to drive the cutting table to move towards a material collecting table; allowing the window passing signal to trigger the electromagnetic valve to allow the push rods of the cylinders to push the cloth pressing rod to press the cloth to the cutting table so as to allow the cloth to move with the cutting table; after window passing, allowing the electromagnetic valve to drive the cloth pressing rod to lift from the cloth, and finishing the cloth pressing process. Synchronous motion of the cloth and cutting table is guaranteed, and the automatic window pass of the cloth is implemented.

Description

technical field [0001] The invention relates to the technical field of an automatic cutting bed, in particular to an automatic cutting bed pressing device and a cloth pressing method. Background technique [0002] The automatic cutting bed is used in the garment cutting process, using the computer-aided design setting data to control the movement direction of the cutter to produce the required pieces, and can automatically complete the whole process of board making, nesting, spreading and cutting . [0003] An automatic cutting bed is a complex system with a computer and corresponding programs. Its working principle is to fix the cloth in the cutting area of ​​the cutting table after vacuum adsorption, and use the rotation of the cutter and the up and down reciprocating movement to cut the cloth. While cutting in large quantities, it is necessary to ensure the cutting accuracy of the fabric, and ensure the work efficiency and product quality of the garment enterprise. [...

AI Technical Summary

Problems solved by technology

When the cut fabric is relatively thick, due to the absence of a suitable cloth pressing device, the friction between the cut piece and the cutting table or bristle brick is small, especially for high-level automatic cutting machines, which will cause the cutting table or bristle brick to drag If the fabric does not move, the cutting table or the bristle bricks will always slip under the fabric, causing the next window of fabric to be unable to be accurately delivered to the designated position and automatically cut, thus affecting production efficiency and unable to fully realize the optimal delivery of automatic processing fabric pieces

In order to ensure the friction between the fabric piece and the cutting table or bristle brick, some operators will press their body directly on the fabric to drag the fabric, so there is a serious safety hazard in the process
