Novel cloth clamping device

Abstract

The invention discloses a novel cloth clamping device for a computer embroidery machine. The device comprises a base board and two chain wheels mounted on the base board; a middle partition board is arranged between the two chain wheels, two small chain wheels are arranged on a left partition board, and a press plate is arranged above the two small chain wheels correspondingly; and special chains are arranged on the two chain wheels and two small chain wheels provided, and the chain has hollow pin shaft and is provided with an elastic pin structure. The device uses movement track of the chains to drag the cloth to move, in order to reach the purpose of increasing pulling force; when the cloth is pulled into a cloth sliding rail, under the action of the press plate with wedge structure, the needles press a certain distance towards to needle tip direction and prick into the cloth; and in the traction of cloth, the needles drive the chains to move along the chain wheels, and needles prick into the cloth in order from the chain wheel pin shafts. Due to the movement track of the chains, the needles move a certain distance in the X direction along the sliding groove, and pull the cloth in the X direction to a certain distance, so the relaxing cloth will be tightened. The device improves the quality of the embroidery, makes the embroidery stitch surface neat and shows clear stitch seam.

Description

technical field [0001] The invention relates to a novel cloth clamping device for a computer quilting embroidery machine. Background technique [0002] The computerized quilting embroidery machine has no tension in the X direction during the embroidery process, and the fabric is in a loose state, which affects the precision of embroidery during embroidery. Therefore, it is required to design a set of cloth clamping device in an effective space. On the one hand, it can solve the problem of tension in the X direction. On the other hand, the precision of embroidery can be improved, and a new set of cloth clamping device is designed in consideration of two aspects. [0003] During the embroidery process of the computer quilting machine, although the embroidery is supported by the embroidery frame, there is no tension in the X direction of the computer quilting machine, and the fabric is still in a loose state, which affects the quality of the embroidery during embroidery. The q...

AI Technical Summary

Problems solved by technology

[0004] The main technical problem to be solved by the present invention is to prevent the cloth in the X direction from being in a relaxed state when the computerized quilting machine is embroidering, and to increase the tension, so that the embroidery will not be deformed and out of shape, and the quality of the embroidery can be better improved
