Cloth fixing mechanism on embroidery frame of embroidery machine

Abstract

The invention relates to a cloth fixing mechanism on an embroidery frame of an embroidery machine. The fixing mechanism comprises a fixing clamping seat fixedly connected onto the embroidery frame andhaving an open clamping groove as well as a clamping assembly capable of being matched with the open clamping groove and clamping and fixing cloth, a first stop part and a second stop part are formedon two sides of the opening of the open clamping groove in the width direction, and the clamping assembly at least has a clamping use state in which the clamping assembly is capable of being matchedwith the open clamping groove to fix the cloth. The fixing mechanism can better tension and fix the cloth after clamping the cloth in the open clamping groove, can avoid looseness and deflection of the cloth and guarantee the embroidery quality when larger tension is produced during embroidery, is very convenient to operate, requires little force when operating cloth fixation or unlocking actions,is very easy and can reduce labor intensity and improve work efficiency of an operator; the fixing mechanism is smaller in overall structure, and can effectively reduce overall weight of the embroidery frame and save energy consumption.

Description

technical field [0001] The invention relates to a cloth fixing mechanism on an embroidery frame. Background technique [0002] The embroidery machine is a kind of embroidery machine, which is used to embroider various patterns on the fabric. It is a machine with a high degree of automation developed from manual embroidery. At present, the head of the computerized embroidery machine is in the process of embroidery. It is static, and the embroidery process is realized by the reciprocating plane movement of the embroidery frame on the X, Y horizontal plane and the regular movement of the embroidery needle up and down, while the embroidery frame is moved by the embroidery frame driving guide rails set horizontally and vertically. Before the embroidery machine is used, the cloth needs to be tensioned and fixed on the embroidery frame, and then the embroidery frame is fixed on the workbench of the embroidery machine, and then the embroidery operation is performed. [0003] In the...

Problems solved by technology

[0003] In the prior art, the way of tensioning and fixing the cloth is mostly to fix the raised semicircular seat body 60 around the frame, after the cloth is laid on the frame and covered on the raised semicircular seat body 60 , and then press the cloth pressing strip 50 with the groove cooperating with the seat body 60 to the seat body, so that the cloth is pressed and fixed between the cloth pressing strip 50 and the seat body 60 (such as Image 6 shown); however, in the actual embroidery process, due to the increased tension of the embroidery thread on the fabric, the fabric clamped between the cloth press strip and the seat body is prone to move, and the pattern will shift when the fabric is offset, resulting in waste products Therefore, this method of fixing the cloth reduces the qualified rate of the product and increases the production cost of the enterprise; moreover, the pressing operation of the cloth pressing strip needs to be pressed manually, and the fixing and dismounting operations are laborious, which affects the work efficiency. The height of the cloth pressing strip and the deck is very high, and the weight is relatively heavy, which brings a certain burden to the operation of the embroidery frame drive guide rail, high energy consumption and reduced service life of the drive guide rail; this problem has become an industry Pain point, there are also some other fixing structures to fix the fabric, such as: Chinese patent CN202898764U and Chinese patent application CN106283434A and other mechanisms for fabric fixing, some of these fabric fixing mechanisms are not really effective in fixing the fabric Improvement, some are very complicated and unreasonable in structure, and there are still frequent problems in real use
