Full-automatic U-shaped ultrasonic top stop machine and feeding device thereof

Abstract

The invention discloses a full-automatic ultrasonic welding U-shaped double-top-stop machine for nylon zippers. The machine comprises a zipper passing part and a wire conveying part; the wire conveying part comprises a wire conveying mechanism and a forming mold; the wire conveying mechanism comprises a pair of wire conveying bases which are symmetrically arranged; wire guide bases are arranged at the edge of one side of each wire conveying base; guide rails allowing flat plastic wires to pass through are arranged on the wire guide bases; and a first wire conveying and pressing rod and a second wire conveying and pressing rod are further arranged on each wire conveying base from bottom to top, wherein one end of the first wire conveying and pressing rod and one end of the second wire conveying and pressing rod are movably arranged on the wire conveying base through rotating sleeves, the other end of the first wire conveying and pressing rod and the other end of the second wire conveying and pressing rod abut against the flat plastic wires in the guide rails of the first wire guide base and the second wire guide base respectively and abut against inclined surface ends of the flat plastic wires respectively, and the second wire conveying and pressing rod is connected to a wire conveying air cylinder capable of driving the second wire conveying and pressing rod to rotate upwards. According to the machine, the first wire conveying and pressing rods carry out wire conveying, the second wire conveying and pressing rods prevent the flat plastic wires from backing up, the overall structure is simple, two U-shaped top stops can be formed and welded at a time, and the efficiency can be improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a fully automatic U-shaped ultrasonic top stop machine. Background technique [0002] The existing full-automatic nylon zipper ultrasonic welding U-shaped double top stop machine forms the plastic flat wire into the top stop grain in the same way as the bottom stop grain of the traditional bottom stop machine. The whole machine, especially the wire feeding structure quite complicated. Moreover, the existing U-shaped top-stop machine can only complete one work at a time in the process of welding up-stop, which is low in efficiency, and the welding effect and precision need to be further improved. Therefore, there is a belt to develop an ultrasonic top stop machine with a relatively simple wire feeding structure and high forming and welding efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and...
