Zipper teeth detectors, zipper teeth detection method and zipper injection machine using detectors

Abstract

The invention provides zipper teeth detectors, a zipper teeth detection method and a zipper injection machine using the detectors. Each zipper teeth detector comprises a base, at least a detection mechanism and induction mechanisms, wherein the base is provided with a chute for a zipper tape to pass through; the detection mechanism comprises a rod body, a detection rod and an elastic component; the rod body is pivotally arranged on the base; the detection rod is arranged at one end of the rod body and is provided with a probe; the elastic component is used for applying elastic force to the rod body to ensure the probe on the detection rod on the rod body to be contacted with the zipper teeth on the zipper tape in an elastic manner; and when the zipper tape moves relative to the base, the induction mechanism is used for detecting and judging the movement of the probe. The zipper teeth detectors can automatically detect the zipper teeth defects on the single zipper, thus effectively reducing the work of the operators. The zipper injection machine has the capability of detecting the zipper teeth subjected to injection molding and has higher degree of automation.

Description

technical field [0001] The invention relates to a chain element detector, a chain element detection method and a zipper injection molding machine using the detector, in particular to a chain element detector, a chain element detection method and the A zipper injection molding machine using this detector. Background technique [0002] At present, the chain belts of general plastic-steel zippers are manufactured by zipper injection molding machines. The zipper injection molding machine has an injection molding mold, and the injection molding mold generally has two rows of fastener element cavities. The injection molding mold can continuously form rows of zipper elements on the opposite sides of the two parallel cloth belts to form two zipper single chains. Combine the two single strands to get a zip chain. In the follow-up processing, the zipper chain belt needs to be dimensioned, that is, a section of chain teeth is cut off from the long chain of the zipper at a certain d...

AI Technical Summary

Problems solved by technology

[0003]However, in the process of injection molding single chain of zipper, due to the small size of the upper chain elements of the single chain, a large number needs to be molded on the cloth tape, which often occurs Various structural defects

More commonly, half teeth 74a are formed on the chain belt 70 due to the blockage of the sprue gate of the injection molding mold cavity (such as Figure 7), if this defect is not solved, it will seriously affect the quality of injection molding single chain

This just means that in the production process, special personnel are needed to constantly check the formed chain belt 70, which is obviously unfavorable for the automatic production of the zipper injection molding machine.
