A material transfer mechanism and sleeve fork sewing equipment

Abstract

The invention provides a material shifting mechanism, which includes an outer pressing plate and an adjusting plate for pressing the cut pieces on the platen, the outer pressing plate has a groove in it, and the outer pressing plate and the adjusting plate Hinged to each other and connected by screw locking, the outer binder plate can swing left and right around the hinge center O2 of the outer binder plate and the adjustment plate, so that the left side or right side of the groove moves along the Y direction. Extend straight. In this application, the left and right position of the outer binder plate can be adjusted in a small range through the structure that the outer binder plate can swing left and right around the hinge center O2 of the outer binder plate, so as to ensure that the left side of the groove in the outer binder plate is The groove wall and the right groove wall extend straight forward and backward along Y, and then when the material moving mechanism drives the cutting piece to move relative to the needle bar and the needle installed at the lower end of the needle bar during the sewing process, it can effectively avoid the left side of the groove. The side groove wall and the right groove wall collide with the needle bar.

Description

[0001] This application is a divisional application, the application number of its parent case is 201710993326.2, the application date is October 23, 2017, and the invention name is "a material transfer mechanism and sleeve fork sewing equipment". technical field [0002] The invention relates to a material transfer mechanism. [0003] The present invention also relates to a cuff sewing device comprising the above-mentioned material transfer mechanism. Background technique [0004] At present, when sewing sleeve forks, the small pieces are first placed on the hemming mechanism of the sleeve fork sewing equipment for hemming, and then the large pieces are placed on the small pieces, and then moved by the arm of the sleeve fork sewing equipment. The material mechanism transfers the large cut piece and the small cut piece together to the sewing head in the sleeve fork sewing equipment for sewing. At present, the material transfer mechanism is generally composed of a whole pres...

AI Technical Summary

Problems solved by technology

At present, the material transfer mechanism is generally composed of a whole pressing plate, and the pressing plate is driven by the manipulator to move. However, due to the particularity of the needle track (that is, the stitching of the sleeve fork) when the sleeve fork is sewn, the integral structure of the pressing plate does not It is suitable for the sewing of sleeve yoke; in addition, if the pressure plate is made too large, although it can drive large pieces with a large area to move, but during the moving process, small pieces are prone to wrinkles, which will affect the sleeve yoke stitches aesthetics; if the pressure plate is made too small, although it can avoid wrinkles in the small pieces, it is prone to the phenomenon that it cannot drive the large pieces to move, which will eventually lead to the aesthetics of the sleeve cross stitches.

Therefore, the material shifting mechanism in the prior art cannot move large and small pieces well, and is unfavorable for the formation of sleeve cuff stitches, so it is not suitable for sleeve cuff sewing
