Equipment for detecting sharp edge and sharp point of edge of textile

Abstract

The invention discloses equipment for detecting a sharp edge and a sharp point of an edge of a textile. The equipment comprises a testing instrument, a silicone rubber shaft sleeve, a single-layer self-adhesive test tape, and a tool clamp. The sharp edge and sharp point of the edge of the tested textile can be objectively reflected through the split degree of the test tape, so that an acceptable product and a waste product can be distinguished. Subjective error judgment of a manual test is overcome, and the quality of the product is improved. The skin of a user is protected against puncturing and cutting by the edge of the textile, so that the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to a detection instrument, in particular to a detection device for sharp edge and sharp point of textile edge. Background technique [0002] In medical equipment such as respiratory masks, tubular textile straps are required. Traditional tubular textile straps are produced by sewing, and the stitched parts are not smooth and beautiful. Moreover, the stitched parts are prone to flocculent burrs or loose edges. The patent application document whose publication number is CN104228057A discloses a method and special equipment for making a sheet-like piece into a tubular piece, and the patent application document whose publication number is CN104191601A discloses a method and special equipment for edge sealing of a tubular piece. Both methods use ultrasonic waves to seal the edges while die-cutting, which solves the defects that the stitching parts of traditional stitching products are not smooth enough, beautiful, and easy to form floc...

AI Technical Summary

Problems solved by technology

[0002] In medical equipment such as respiratory masks, tubular textile straps are required. Traditional tubular textile straps are produced by sewing, and the stitching parts are not smooth and beautiful, and the stitching parts are prone to flocculent burrs or loose edges.

The patent application document whose publication number is CN104228057A discloses a method and special equipment for making a sheet-like piece into a tubular piece, and the patent application document whose publication number is CN104191601A discloses a method and special equipment for edge sealing of a tubular piece. Both methods use ultrasonic waves to seal the edges while die-cutting, which solves the defects that the stitching parts of traditional suture products are not smooth enough, beautiful, and easy to form flocculent burrs or loose edges, but it also brings new problems.

[0003] Textile products or leather products formed by ultrasonic die-cutting will cause the edges of the products to harden, and there may be sharp edges and sharp points. During the use of the products, there is a potential danger of stabbing and cutting the user's skin. Detection of sharp edges and sharp points of products

[0004] The current inspection method is to manually touch the product by hand, relying on manual feeling to judge whether the product is qualified. This inspection method is very subjective and the standards cannot be unified. Moreover, the difference between unqualified products and qualified products is relatively subtle. Phenomena that cannot be distinguished by humans often occur
