Gold plaque and bead tube cutting device

Abstract

The invention discloses a gold plaque and bead tube cutting device, of which a blade of a moving cutter cannot exceed the lower bottom surface of a stationary cutter, and the quality of embroidery is high. The gold plaque and bead tube cutting device comprises the stationary cutter, and the moving cutter matched with the stationary cutter, wherein the moving cutter comprises the blade and a cutter back; the moving cutter is driven by a needle bar with a needle clamp; an extension part is formed at the front end of the cutter back of the moving cutter; the end face of the extension part of the cutter back is contacted with the bottom face of the needle clamp during the descending of the needle bar; and after the moving cutter is matched with the stationary cutter so as to cut off the gold plaque or the bead tube, the end face of the extension part of the cutter back is separated from the bottom face of the needle clamp before the blade of the moving cutter and the lower bottom face of the stationary cutter are horizontal. The gold plaque and bead tube cutting device is suitable for cutting the gold plaque or the bead tube in a computer embroidery machine.

Description

technical field [0001] The invention relates to a computerized embroidery machine, in particular to a cutting device for cutting sequins or bead tubes. Background technique [0002] In the computerized embroidery machine sequin or bead tube embroidery process, since the conveying device transports the sequin chain or bead tube chain, the sequin chain is composed of pieces of sequins connected end to end. Sequin embroidery can only be carried out after the top is cut off, and the bead tube chain is composed of bead tubes connected to each other. Send the gold piece or bead tube at the front to the bottom of the moving knife so that the edge of the gold piece or bead tube corresponds to the edge of the moving knife. When the moving knife goes down, the gold piece is Or the bead tube is cut from the gold piece chain or the bead tube chain, and the embroidery needle that goes down at the same time as the moving knife embroiders the gold piece or bead tube onto the embroidered c...

AI Technical Summary

Problems solved by technology

At present, the movement of the moving knife is generally driven by the needle bar, that is, when the needle bar goes down, the needle clamp on the needle bar will touch the back of the moving knife, so that the moving knife goes down with the needle bar going down. In general, The moving knife will not touch the embroidery even if the blade exceeds the lower bottom of the fixed knife. The height is high, so that the distance between the embroidery and the bottom of the fixed knife is relatively close. When the blade of the moving knife exceeds the position of the bottom of the fixed knife, the blade of the moving knife will cut the embroidery, causing damage to the embroidery and affecting the embroidery quality
