Abstract

The invention discloses an automatic mounting machine of bra back fasteners. The automatic mounting machine comprises a machine frame, a work table board, a lower butterfly-shaped fastener mold feeding device, an upper butterfly-shaped fastener mold feeding device, an ultrasonic plastic welding device, a cloth belt dragging device, an ultrasonic power source, a programmable logic controller and an operating display screen. The work table board is horizontally placed on the top of the machine frame. The lower butterfly-shaped fastener mold feeding device is fixed to the left end of the work table board, the upper butterfly-shaped fastener mold feeding device is fixed to the right end of the work table board, and the ultrasonic plastic welding device is arranged in the center of the work table board and located between the lower butterfly-shaped fastener mold feeding device and the upper butterfly-shaped fastener mold feeding device. The cloth belt dragging device is arranged at the front end of the work table board and located in front of the ultrasonic plastic welding device. The operating display screen is in circuit connection with the programmable logic controller and provides man-machine interface programming operation. According to the invention, the butterfly-shaped fasteners of bras can be automatically produced, the production efficiency is greatly improved, material loss is reduced, and the quality of the fasteners of the bras is improved.

Description

technical field

[0001] The invention relates to an automatic mounting machine for back buttons of bras. Background technique

[0002] Brassiere is one of the underwear used by modern women. The back button part of traditional bras uses a structure of metal buckles arranged in a matrix and a row of metal hooks, which are connected by the cooperation of buckles and buckles.

[0003] Now people have innovated on the back buckle part of the bra, and developed a new plastic buckle assembly to replace the existing buckle ring and hook. It is fixed on the left end of the strap of the bra, and the hook plastic part is fixed on the right end of the strap of the bra. The butterfly-shaped plastic buckle and the plastic hook are connected together; the butterfly-shaped plastic buckle needs to be machined and fixed on the fabric strip, and the butterfly-shaped plastic buckle It is formed by fusing the butterfly button upper mold and the butterfly button lower mold. The existing machinin...
