Serger pay-off mechanism used for automobile seat cushion production

Abstract

The invention discloses a serger pay-off mechanism used for automobile seat cushion production. The serger pay-off mechanism comprises a mounting fixation seat. A first groove is fixedly formed in theupper surface of the mounting fixation seat, a second groove is fixedly formed in the side, close to the first groove, of the upper surface of the mounting fixation seat, and a third groove is fixedly formed in the side, close to the second groove, of the upper surface of the mounting fixation seat. According to the serger pay-off mechanism, through a thread combing assembly, the problem that sewing thread on various bobbins is mutually intertwined in the pay-off process of the serger pay-off mechanism is fundamentally solved; when the sewing thread on the bobbins is used thoroughly, a limitplate can be taken off the mounting fixation seat through a limit assembly, and accordingly, the bobbins and sewing thread can be replaced with new bobbins and sewing thread conveniently; and throughheight adjusting assemblies, the distance between the thread combing assembly and the bobbins can be adjusted, accordingly, the pulling angle of the sewing thread can be adjusted, and the sewing thread is not abraded in the pay-off process.

Description

technical field [0001] The invention relates to the field of automobile seat cushion production, in particular to a wire-feeding mechanism of an overcoat machine for automobile seat cushion production. Background technique [0002] Car seat cushions are the main consumer goods for car owners. It is especially important to choose a set of comfortable and practical car seat cushions according to the season. Nowadays, there are car cushions made of different materials such as genuine leather, microfiber leather, artificial leather, nylon, chemical fiber, artificial fur, and polyester wool. When using seat cushions and car seat cushions in production and processing, the corners need to be stitched with the help of an overlay machine. It also plays an aesthetic role. The pay-off mechanism is one of the important components of the edge machine. [0003] However, the pay-off mechanism of the existing overlay machine is not only complicated in structure, but also has a single funct...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a wire-off mechanism for the overcoating machine used in the production of automobile seat cushions, which can effectively solve the problem that the wire-off mechanism of the overcoating machine in the background technology is not only complex in structure, but also has a single function. It is not suitable for the production and processing of car seat cushions. During the use of the overcoating thread pay-off machine, the sewing thread on each thread barrel is easy to be entangled during the process of unwinding, and after winding, the slight winding can be loosened manually. However, it is time-consuming and labor-intensive. For heavy winding, new thread cylinders and sewing threads must be replaced, which increases the cost of production and processing, and the thread after winding will largely enter the interior of the copying machine. The edge machine itself causes a certain amount of damage; the pay-off mechanism of the edge machine is fixed in height, and it is easy to cause friction with the edge machine when it is unwound, which will cause the wear of the sewing thread itself and affect the edge overlay in the production process of the car seat cushion. quality problems
