Continuous sewing production line and method for bandage with hook-and-loop fasteners

Abstract

The continuous sewing production line comprises a bandage unwinding device, the output end of the bandage unwinding device is provided with a fixed-length cloth feeding and cutting mechanism, the fixed-length cloth feeding and cutting mechanism is matched with a fixed-length material taking and overturning mechanism, and the fixed-length material taking and overturning mechanism is used for grabbing the bandage in a fixed-length mode and overturning the bandage; a workbench is arranged between the fixed-length cloth feeding and cutting mechanism and the fixed-length material taking and overturning mechanism, a transfer arm mechanism is arranged above the workbench and used for conveying bandages to be sewn to a sewing device, an automatic coiling mechanism is arranged at the output end of the sewing device, and a hook-and-loop fastener feeding mechanism is arranged between the sewing device and the fixed-length material taking and overturning mechanism. The hook-and-loop fastener feeding mechanism is used for stacking hook-and-loop fasteners on bandages to be sewn. The invention provides an automatic production process for sewing the magic tapes at the two ends of the bandage, and the function of continuously producing the bandage with the magic tapes is realized.

Description

technical field [0001] The invention belongs to the technical field of production of medical dressing products, and in particular relates to a continuous sewing production line and method for bandages with Velcro. Background technique [0002] Bandage with Velcro refers to a bandage product formed by setting Velcro at both ends of an ordinary bandage. Both ends of the Velcro need to be fixed (fixing methods include sewing, pasting or ultrasonic welding). Two different faces, one set on the obverse and one set on the reverse. At present, this product is basically produced manually, and the work efficiency is low. Therefore, designing an automatic continuous production line is the future research and development direction. Chinese patent document CN 108175571 A (the patented technology applied by our company) discloses "a medical elastic bandage with Velcro and its manufacturing method and equipment", which provides a feasible technology for the automatic production of bandag...

AI Technical Summary

Problems solved by technology

[0003] But the main problem existing in the prior art is: Utilize the velcro bandage of ultrasonic welding, the hardness of velcro and bandage connection position is high, lost the comfortable feeling of bandage body, and this product bandage will bring bigger foreign body sensation to patient when using , so it is gradually eliminated by the market

[0004] The existing secondary problems are as follows: 1. The current lockstitch sewing machines do not have the function of backstitching, and it is easy to have thread off-line problems at both ends of the Velcro

2. There is no device for cutting and flipping the bandage at a fixed length, and it is impossible to sew both ends of the bandage at the same time
