Adsorption assembly for front fly hole locking device

Abstract

The invention discloses an adsorption assembly for a front fly hole locking device. The adsorption assembly for a front fly hole locking device is characterized by comprising a base, an adsorption plate, a frame plate, an upper cover plate, a connecting pipe, a connecting assembly, an air cylinder and a reset assembly; the integral base is a U-shaped plate with a downward opening; the frame plate is provided with an airflow channel runs through the frame plate; the frame plate is hinged to the base through the connecting assembly; the frame plate is driven by an air cylinder to rotate downward; the reset assembly is arranged between the frame plate and the base and the frame plate is driven to rotate upward by the reset assembly; the adsorption plate is connected to and fixed on the lower side of the frame plate in a closed mode; the upper cover plate is connected to and fixed on the upper side of the frame plate in a closed mode from top to bottom; the adsorption plate is provided with an induced draft hole group and a communication hole; the induced draft hole group is provided with a plurality of induced draft holes which are distributed in a matrix mode; the induced draft holes are communicated with an air inlet portion of the airflow channel. The adsorption assembly for a front fly hole locking device has the advantages of being large in adsorption force and large in adsorption covering area and thoroughly solving the problem that thin materials and soft materials are easy to generate displacement during the feeding process.

Description

technical field [0001] The invention relates to the technical field of clothing sewing equipment, in particular to an adsorption component for a door buttonhole equipment. Background technique [0002] Our country is one of the main garment producing areas, so various garment sewing equipments have come into being. With the continuous rise of labor costs, the requirements for automation of garment sewing equipment are getting higher and higher. Buttonhole machine is a very important equipment in garment machinery, and it is mainly used to process buttonholes in various garments. The keyhole machine system generally consists of nine mechanisms: feeding mechanism, crochet mechanism, needle bar mechanism, stretching mechanism, hook mechanism, upper knife mechanism, sliding table mechanism, and thread dividing mechanism. Each set of institutions has its own characteristics and functions, and is relatively independent, but they work closely together and coordinate with each oth...

AI Technical Summary

Problems solved by technology

The main technical problem to be solved is to provide an improved keyhole machine tool that does not displace the cloth when it is pressed, has a simple structure, is convenient to debug and has a relatively large pressing surface, but it is suitable for different materials, especially thin materials. 1. For soft materials (such as silk fabrics), due to the discontinuity of the distribution of the pressing feet, the fabric cannot be completely fixed, and the problem of fabric displacement still exists

Secondly, the structure is relatively complicated, the production cost is high, and the debugging and maintenance are troublesome.
