Full-automatic double ultrasonic U-shaped upstops of nylon zip fastener

Abstract

The invention discloses full-automatic double ultrasonic U-shaped upstops of a nylon zip fastener, comprising a stand, a plastic flat wire cutting and bending forming mechanism, a chaining-passing positioning mechanism, a pull head signal inducing mechanism, an elastic zip fastener mechanism, a chain-dividing mechanism and a welding and melding mechanism. The invention utilizes the ultrasonic melding technology, uses one welding head to simultaneously meld the U-shaped plastic flat wire upstops at the left and the right of the nylon zip fastener by a full-automatic production mode, and has the advantages of reasonable structure, reliable performance, high production efficiency, stable product quality, and the like.

Description

technical field [0001] The invention relates to a nylon zipper production equipment, specifically a full-automatic nylon zipper ultrasonic U-shaped double top stop machine. Background technique [0002] The existing fully automatic nylon zipper ultrasonic U-shaped double top stop machine uses two sets of vibrating electric boxes, vibrators, and welding heads to weld the U-shaped double top stop of the nylon zipper at the same time, and molds the plastic flat wire The way to reach the U-shaped upper stop is the same as that of the traditional bottom stop machine, which requires inner and outer cutters, telescopic dies, and punches. Therefore, the existing full-automatic nylon zipper ultrasonic U-shaped double top stop machine has large volume and high manufacturing cost. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention aims to provide a fully automatic nylon zipper ultrasonic U-shaped double top stop machine. [0004] T...
