Automatic zipper machine

Abstract

The invention discloses an automatic zipper machine with an automatic zipper tooth missing detection device and belongs to the field of mechanical equipment. The automatic zipper tooth missing detection device comprises a base and a connecting plate arranged on the base; the end surface of the base facing to the connecting plate is provided with a zipper channel, an infrared emitter is arranged above the zipper channel, and an infrared sensor corresponding to the infrared emitter is arranged under the zipper channel. The traditional rolling ball detection is replaced with the infrared emitter; the reliability and stability of detection are improved, and the automatic zipper machine is adaptive to tooth missing detection of various zippers and is adaptive to various zipper production companies; the structure is simple, the detecting process is free of manual operation, and the detecting efficiency is improved greatly; a transparent protecting layer is arranged above the infrared sensor and is capable of protecting the infrared sensor better; since the height of the infrared emitter on a support can be adjusted vertically, the device can be adaptive to tooth missing detection of various zippers.

Description

technical field [0001] The invention relates to an automatic zipper machine, in particular to an automatic zipper machine with an automatic detection device for zipper missing teeth, belonging to the field of mechanical equipment. Background technique [0002] As a zipper processing and manufacturing equipment, the zipper machine can process a variety of zippers. After the traditional zipper is formed, the finished product is output to the finished product end through the conveying system, and then the output zipper products are manually inspected to remove the zipper products with missing teeth in the zipper products. Due to the low accuracy of manual inspection, the overall pass rate of products has decreased, and at the same time, the input of human labor has been increased, and the manufacturing cost has been increased. [0003] On March 27, 2013, the Chinese utility model patent CN202823919U disclosed a device for automatically detecting missing teeth in a zipper in a ...

AI Technical Summary

Problems solved by technology

Due to the low accuracy of manual inspection, the overall pass rate of products has decreased, and at the same time, the input of human labor has been increased, and the manufacturing cost has been increased.

[0003] On March 27, 2013, the Chinese utility model patent CN202823919U disclosed a device for automatically detecting missing teeth in a zipper in a zipper machine. Improve the detection efficiency and quality of zipper missing teeth, but also have the following defects at the same time: (1), can not adapt to the missing teeth detection of zippers with different chain element gaps

The device can only touch the sensor head when the balls drop obviously, and the balls cannot be replaced at will, so it cannot be detected for zippers with relatively small gaps between the chain teeth

(2) The structure of the device is complex, and it is inconvenient to use during detection. When the tooth is detected and the machine stops, the ball cannot automatically return to its position, and the detection process needs to be resumed manually.

(3), poor reliability

Due to the use of mechanical structure for detection, it is easy to cause mechanical failure during long-term operation, which affects the detection efficiency and reliability
