大连吹膜机组如何选择合适的规格和型号？

The application range of blow film machines is very wide. In the field of agriculture, blow film machines can be used to manufacture agricultural plastic films, covering films, etc. Agricultural plastic film can be used to protect crop growth, increase soil temperature and humidity, and control grass and weeds in the soil. Covering film can be used for seedling cultivation, insulation, and other purposes. In the medical field, blow film machines can be used to manufacture medical films, infusion bags, etc. for surgical purposes. In the field of food, blow film machines can be used to manufacture food packaging bags, cling films, etc. In the industrial field, blow film machines can be used to manufacture waterproof films, fence films, etc.

In terms of maintenance and upkeep, there are also some issues to pay attention to in the blowing film unit. When using the blowing film unit, it is necessary to ensure the cleanliness and hygiene of the equipment, and no impurities should be mixed in; Secondly, regular maintenance and inspection of various machine components are required, and worn parts should be replaced in a timely manner to avoid accidents. In addition, regular cleaning and lubrication are required, and special attention should be paid to the maintenance of small components such as the machine head to maintain the set specifications and quality standards of the finished product.

How to choose the appropriate specifications and models for Dalian blow film units?

1、 The requirements for production technology mainly include the quality of finished products, process flow, and production cost of products. Choose different specifications and models of equipment according to different production process requirements. For example, if you need to produce wide composite films, you need to choose a larger unit; If you need to produce high-quality films, you need to choose a relatively high-end blow molding machine.

2、 The requirements for production scale mainly involve the project team's consideration of investment costs, equipment purchase costs, maintenance, and other factors. Equipment specifications and models need to be selected based on the size of production scale and budget. Large production companies can choose giant blow molding machines, while small businesses need to choose small blow molding machines appropriately.

3、 The production capacity of the equipment should match the requirements of the process level, and different equipment should be selected for production according to production needs. Production capacity and process level are important indicators of blown film machines. The thickness, swing, and speed of the thin film produced by the equipment reflect the production capacity and process level.

4、 The limitations and requirements of installation space mainly include the occupied area of the equipment, as well as factors such as distance from other equipment and drainage. Select appropriate equipment based on the actual situation of the site and the requirements of the production site.

The main components of the blown film unit include an extruder, die head, cooling rollers, traction device, cutting device, winding device, etc. The main function of an extruder is to heat and melt polymer compounds, and extrude them into shape. The mold head is a very important component in the blown film unit, responsible for extruding the synthetic resin and forming the desired film shape. The function of the cooling roller is to rapidly cool the thermoplastic material in order to maintain its desired shape and size.

The main principle of the blown film unit is to extrude a certain plastic particle through the screw equipped in the extruder, making it a uniform fluid state, and then forming a thin film through the die head.
