Problems solved by technology

The applicant of the present invention found that although this manufacturing method can solve the problems of cold resistance, heat resistance and durability to a certain extent, in the process of implementing the patented technology for production, it was found that the materials often twisted during the cutting step and curling, which seriously affects the production efficiency and product qualification rate
It is also found that the product is bonded with a lot of dust during the production process, which also increases the failure rate of the final product
In addition, the technology of this patent application also has shortcomings such as insufficient cooling effect
The cooling effect directly affects the quality and production efficiency of the product, and is a very important factor in the manufacturing process. If the temperature cannot be well controlled, the product will be scrapped and the production efficiency will be seriously reduced.

Embodiment Construction

[0037] like figure 1 As shown, according to the preparation process of the plastic hook and loop fastener of the present invention, the toughened nylon material is melted in an extruder 2 equipped with a double coil (or single coil) 1, and extruded by a melt pump 3 After passing through the smooth sheet-shaped die 4, it becomes a continuous sheet and enters the traction mechanism. The tooth-forming roller 5, which is composed of a plurality of circular metal sheets with hook teeth, is rolled on the soft sheet to manufacture hooks. After the teeth, it enters the flat pressing roller 7 with an industrial chiller 6 for rolling and shaping, and then passes through the de-static machine 8 to remove dust. Buckle the product and finally pack it. The extruder 2 is equipped with a heating device, and the temperature under working conditions is 180°C-250°C (the temperature in the hot season is about 190°C, and the temperature in the cold season is about 240°C, and the temperature chang...

Abstract

Provided are a manufacturing method and device for plastic hook piece fastening tape and the plastic hook piece fastening tape. According to the method, a toughening nylon material is melted in an extruding machine and becomes continuous sheets through a smooth piece-shaped die to enter a traction mechanism; after hook teeth are manufactured by enabling a tooth-making roller to roll on the soft sheets, the sheets enter into a flat pressing roller to undergo rolling, then dedusting is performed through an anti-static machine, and the strip-shaped sheets provided with the hook teeth and undergoing rolling are slit through a slitting machine to form fastening tape products. The plastic hook piece fastening tape manufactured by the method has the advantages of being high efficiency and excellent in cold resistance, heat resistance and durability and the like.

Description

technical field [0001] The invention relates to a preparation process of a hook-and-loop fastener, in particular to a preparation process and equipment for a plastic hook-and-loop fastener, and a plastic hook-and-loop hook and loop fastener (ie, an injection hook) manufactured by the method and the device. . Background technique [0002] Velcro, also known as Velcro, was invented by Swiss engineers. It is generally composed of two parts, consisting of a rough surface and a hook surface. When the hook surface and the rough surface are pressed together, the hook on the hook surface will hook the ring on the rough surface, and the two will be fastened together. together. [0003] The whole production process of general hook and loop products is basically as follows: 1. First, the raw material yarn is formed into the shape of the embryo belt by the loom. 2. The semi-finished embryo belt is dyed into various colors by high temperature dyeing equipment. 3. The suede belt of th...
