Description

Tooth punching machine

Technical Field

The utility model relates to a zip fastener processing technology field, more specifically say, it relates to a towards tooth machine.

Background

After the zipper is subjected to injection molding, the zipper needs to be subjected to sizing and tooth punching treatment according to different requirements. The existing tooth punching machine usually counts the number of teeth of the zipper, and then performs the tooth punching operation for sizing. However, in the case of mass production, the sizing method by counting the number of teeth of the slide fastener is inefficient, and cannot meet the production demand.

To solve the above problems, a tooth removing sizing machine disclosed in chinese patent No. CN210382907U, wherein a slide fastener is sized, a driving motor drives a slider to reciprocate, the slider drives a driving wheel to move in a direction away from a lower mold, the driving wheel is limited by a ratchet and a pawl, thereby driving the slide fastener to move, when the pawl contacts an adjusting block, the adjusting block applies a force perpendicular to a first wedge-shaped surface to the driving block, so that the pawl is separated from the ratchet, the driving wheel is not limited in rotation, at this time, the slide fastener is not moved, and at the same time, the driving wheel drives the driving rod to move in a direction away from the lower mold, so that a limiting block is separated from a positioning block, the positioning block moves downward under the action of a spring applied by a second spring to compress the slide fastener, so that the slide fastener is not moved, and at this time, teeth are cut off by. Afterwards the slider removes towards the lower mould, thereby the power of perpendicular to second wedge-shaped surface is applyed to the locating piece to drive wheel and gyro wheel contact, makes locating piece rebound, and the butt groove lower extreme and the spacing groove lower extreme of locating piece are in the coplanar this moment, and the stopper inserts the butt inslot under the effect of the elasticity that first spring was applyed this moment, later can continue to utilize the drive wheel to drive the zip fastener and remove.

The structure is comparatively complicated among the above-mentioned scheme, and the staff is all comparatively troublesome in installation or daily maintenance, and the time of use is longer.

A new solution is therefore proposed to solve this problem.
