Braided bag cover inner film machine is a kind of machine used to produce woven bag inner film. It can make the plastic film into the inner film of the woven bag by heating, blowing and other processes, which is an indispensable link in the production process of the woven bag. However, for most people, the woven bag cover intimal machine is a mysterious existence, and we do not know how it works and how to operate it. This article will reveal the mysterious process behind the woven bag cover intima machine, so that you can understand the operation and production process of this machine.
I. the working principle of the knitting bag cover inner film machine
The inner film machine of woven bag cover is a kind of plastic film blowing machine, and its working principle is based on plastic film blowing technology. It is mainly composed of hopper, extruder, die, cooling water tank, tractor, winding machine, etc. First of all, the plastic particles are put into the hopper, heated and extruded by the extruder, the plastic is melted into a fluid state, and then the molten plastic is extruded into a thin film through a die. The film is then cooled by a cooling water tank, then pulled by a tractor, and finally wound into a drum.
Second, the operation steps of the knitting bag cover inner film machine.
1. Preparation: put the plastic particles into the hopper, turn on the power, and start the machine.
two。 Adjust the extruder: adjust the temperature and extrusion pressure of the extruder according to different types and thickness of plastic to ensure that the plastic can be melted and extruded smoothly.
3. Adjust the die: according to the size and shape of the intima, adjust the size and shape of the die to ensure that the extruded film meets the requirements.
4. Adjust the cooling tank: adjust the temperature and water level of the cooling tank to ensure that the film cools quickly and remains flat.
5. Adjust the retractor: according to the thickness and width of the film, adjust the traction speed and tension of the retractor to ensure that the film can be drawn smoothly and maintain a certain tension.
6. Winding into a reel: the drawn film is wound into a drum so that the next production process can be carried out.
Application of braided bag cover inner film machine
The intima produced by braided bag cover intima machine is widely used in the production of woven bag. A woven bag is a bag used to pack, transport and store goods, usually made of plastic materials such as polypropylene. The inner film of the woven bag is a layer of film inside the woven bag, which is used to increase the tightness and moisture resistance of the woven bag. In addition to woven bag inner film, woven bag cover inner film machine can also produce some other plastic film products, such as plastic bags, plastic film and so on.
Woven bag cover intimal machine is a mysterious machine, but it plays a vital role in the production of woven bags. Through the introduction of this article, I believe you have understood the working principle and operation steps of the woven bag cover inner film machine, as well as its scope of application. With the continuous development of the technology of woven bag cover inner film machine, it will be more intelligent and efficient in the future, which will bring more convenience and benefits for the production of woven bags.
