Embodiment Construction

[0031] Such as figure 1 As shown, a zipper machine main shaft anti-rotation prevention device, in the zipper machine that manufactures zipper stringers through the rotation of the main shaft to perform multiple actions, includes a frame 1, which is rotatably installed on the frame 1 through a bearing 21 The main shaft 2 is non-rotatably installed on the flywheel 3 at one end of the main shaft 2 through the flat key 31; the main shaft 2 is provided with a first overrunning clutch 4, and the first overrunning clutch 4 is fixed on the frame 1, and the first overrunning clutch 4 can According to the positive and negative rotation of the main shaft 2, it can be clutched automatically.

[0032] The overrunning clutch is a basic component that appears with the development of mechatronics products. It is an important component used for power transmission and separation between the prime mover and the working machine or between the driving shaft and the driven shaft inside the machine....

Abstract

The invention provides a reverse rotation prevention device for a spindle of a zipper machine. The zipper machine used for manufacturing zipper teeth chain belts by a plurality of actions performed through the rotation of the spindle comprises a rack, the spindle and a flywheel, wherein the spindle is rotatably arranged on the rack, the flywheel is fixedly arranged at one end of the spindle, and a first overrunning clutch which performs separation and reunion automatically according to forward / reverse rotation of the spindle is arranged on the spindle and is fixed on the rack. Because the overrunning clutch is arranged on the spindle, according to the automatic separation and reunion characteristic of the overrunning clutch, the overrunning clutch is in a separation state when the spindle rotates forwardly, and the normal rotation of the spindle cannot be influenced; and the overrunning clutch is in a reunion state when the spindle rotates reversely, and the spindle is locked tightly and limited in reverse rotation.

Description

technical field [0001] The present invention relates to a zipper machine main shaft anti-rotation preventing device. When the main shaft stops, the main shaft anti-rotation prevents the main shaft from rotating in the direction opposite to that during operation. Background technique [0002] A zipper machine having a forming implant for engaging elements, a feeding device for intermittently feeding metal wires for engaging elements to the engaging element metal wires for forming implants, intermittently feeding the zipper by feeding out the fastener stringers A supply device, etc. for fastener tapes supplied to molded implants. [0003] The technical wire for engaging elements uses a lengthwise metal wire with a circular cross-section formed by a plurality of rolls into a substantially Y-shaped cross-section with a head and a bunch of legs. [0004] The forming implant part of the engaging element has: a cutting device, which has a cutting punch and a cutting die, and cuts ...
