The central feeding system is used more in the plastic industry, such as injection molding, sheet extrusion, cable extrusion, PE film blowing, pelletizing extrusion and other industries. The simple composition of the central feeding system consists of; motor, electrical control, suction Hoppers, conveying pipes, filters, racks, etc., for multiple machines, centralized raw material processing, enclosed conveying and whole plant strength conveying can be designed with different functions according to different production applications. The central feeding system can provide 24 hours of uninterrupted molding machines. For material feeding, the central feeding system has a material shortage alarm. Positive pressure conveying and negative pressure conveying can also be selected for large flow, high power and high-floor suction. PLC technology is used for easy operation. The central feeding system can also be equipped with cyclone dust collection and filtration It is more suitable for centralized management of raw materials.
The composition of the suction machine in the single machine of the central feeding system;
1. Motor; also called vacuum generator, vacuum generator, negative pressure generator, high-pressure fan, high-pressure motor, suction blower, motor power ranges from 0.75KW-30KW, motor types include; carbon type, induction type, high pressure Type, double type, four type, each has different performance and vacuum degree.
2. Electrical control; contactor, PC computer board, thermal overload, inverter, alarm light, suction system, PLC, touch screen, to control the operation of the suction machine to achieve automatic suction, 24 hours Uninterrupted unmanned production
3. Suction hopper; installed on the machine or forming machine to be sucked, connected by pipes as the inlet and suction port, forming a relatively closed container, with a filter separating the raw materials and air in the middle, and the hopper is determined by the suction volume To determine the size, the size of the suction hopper determines the amount of material sucked each time, and the number of fan starts, etc.!
4. The filter of the central feeding system has two functions. One is to filter the air. When the raw material is separated from the air, there will be more or less dust and particles, which will enter the fan and pipeline with the air, which will affect the workshop. The ring ring produces pollution, and the dust damages the ring machine to a certain extent. The second is the cyclone separation effect of the central feeding system, which is used for powder, fine and small particles.
