A production process for steel wire non-woven fabric suspenders

Abstract

The invention relates to a production process for a steel wire non-woven fabric suspending belt. The process steps of the production process for the steel wire non-woven fabric suspending belt are: steel wire plastic coating, unwinding, heating, tablet pressing, cooling, traction, punching Cutting and conveying, the present invention pre-coats the steel wire with a layer of modified PP plastic, and then heat-laminates it with PP non-woven fabric. Since the molecular structure of the modified PP plastic and PP non-woven fabric is similar, the heat-bonded steel wire The bonding force with non-woven fabrics is much greater than that of glue, and the automatic control of the thermal bonding process ensures the bonding quality and avoids the risk of degumming failure; the use of a new type of cooling device greatly improves cooling efficiency and cooling uniformity, and improves product quality; the whole process Automated production, high production efficiency and low cost.

Description

technical field [0001] The invention relates to a production process for a steel wire nonwoven suspending belt, belonging to the technical field of automobile seat suspending belt processing. Background technique [0002] The sling is composed of non-woven fabric and reinforcing strip, and is one of the main connectors in the fixed structure of the car seat cover. The non-woven fabric part of the sling is sewn on the seat fabric, and the reinforcing strip part Then it is connected with the frame of the seat, thereby fixing the fabric on the seat. [0003] The steel wire non-woven fabric sling is made of steel wire as a reinforcement strip and combined with a non-woven fabric belt. The patent (201420238708.6) discloses a process of compounding metal wire and non-woven fabric with glue to form a sling belt. The device, the non-woven fabric and the metal wire, and the non-woven fabric and the non-woven fabric are all bonded by glue, and there is a risk of degumming failure in ...

AI Technical Summary

Problems solved by technology

[0004] The existing production of steel wire non-woven slings is mainly done by manual operation, with only partial automatic production, and the production efficiency is very low; moreover, glue is often used for pasting, which is prone to quality problems such as uneven pasting and degumming. In addition, glue There is also the problem of environmental pollution; in the production process of the existing technology, air cooling is used, and the cooling efficiency is poor and it is easy to produce uneven cooling and cause product quality problems
