A film blowing machine is a piece of equipment commonly used to make plastic films. It can process molten plastic particles into film form through processes such as extrusion and stretching, and is widely used in packaging, agriculture, construction and other industries.
The blow molding machine process began to be used to produce low-density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology was widely used. The volume of hollow containers can reach thousands of liters, and some production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The resulting hollow containers are widely used as industrial packaging containers.
Energy-saving transformation of the power part of the film blowing machine: Most of them use frequency converters. The energy-saving method is to save the residual energy consumption of the motor. For example, the actual power of the motor is 80Hz, but you actually only need 50Hz for production. Those extra Energy consumption is wasted. The frequency converter changes the power output of the motor to achieve energy saving.
In the feeding part, the flexible packaging film fed by the roller is unrolled through a feeding roller. Feed rollers are used to move the film within the machine to perform the required operations. Feeding is usually an intermittent operation, and other operations such as sealing, cutting, etc. are performed during feeding stops. Dancing rollers are used to maintain constant tension on the film roll. To maintain tension and critical feeding accuracy, feeders and dancing rollers are necessary.
A bag making machine is mainly composed of: storage device, stepping device, frequency conversion device, whole bag device, heat sealing cutter and control device. The main feature is that the storage device stores a corresponding amount of raw materials, the stepping device drives the raw materials, and the frequency conversion device drives the heat sealing cutter.
Nowadays, packaging is an indispensable part of current products. Currently, the popular packaging in the market is mainly plastic and paper. The blow molding industry, which mainly uses film blowing machines, has a larger proportion in the market. However, with the requirements of the paper industry Increasingly strict, new indicators of environmental protection and energy conservation have raised the threshold of the paper industry, causing the cost of the paper packaging market to expand and prices to rise.
