Feeding method of central feeding system:

1. Fully automatic feeding system equipment;

2. Central feeding system equipment;

3. Spring feeding system equipment.

Feeding method in the hopper on the central feeding system

When the feeding system hopper needs to be loaded, the fan 2 is started, and the suction pipe 4 and the filter net 3 are used to form a negative pressure in the intermediate storage bin; at the same time, the suction is connected with the intermediate storage bin and the raw material bin. The material pipe 8 sucks the raw materials in the raw material box into the intermediate storage bin. When a certain amount is sucked in, the feeding relay acts, the central system fan stops working, and the suction work stops; at this time, the discharge valve opens to be the extruder hopper The feeding device and the central system function, the central feeding system equipment is composed of a fan, an air suction pipe, a storage bin, a suction pipe, a filter net, an electric control box and the like.

Central feeding system water supply system

The water supply system and power transmission system of the central feeding system are composed of components. In general, the material in the power transmission system reaches the mold from the water tank with the built-in heater and cooler, and then returns to the water tank from the mold on the injection molding machine; the temperature sensor knows the temperature of the warm fluid and transmits the data to the control section. The manipulator; the manipulator then adjusts the temperature of the warm stream, and then leaves the mold back to directly adjust the temperature of the mold.

Vacuum delivery of the central feeding system

The central transport system accepts the vacuum transport method, transports the plastic raw materials from the storage tank to the central drying system via the converging piping system, and then transports the dried material to each injection molding machine. The system is primarily vacuum pumped, and the intermediate dust is filtered. , suction box, intermediate distribution station, transportation pipeline and other components. The intermediate transport system accepts the “one rigid and one tube” planning method, which guarantees that the whole system is stable and there is no blocking phenomenon. It is used in the joint center drying system. The material can be transported in a dry atmosphere to prevent the moisture from re-wetting after drying. At the same time, the transportation pipeline will be liquidated after each transportation cycle to ensure that there are no residual particles in the pipeline, which will help prevent the material from regaining moisture. Improve the quality of the shaped product.

Spring loading system

The spring loading system device device is equipped with a coil spring in a rubber tube, and the spring is directly driven by the motor and can rotate at high speed in the rubber tube. Therefore, when the hopper needs to be loaded, the starter motor will drive the spring to rotate, and the raw material is driven by the spring spiral. The upper end of the rubber tube is opened with a discharge port at the hopper, and the material rising to the discharge port is thrown by the centrifugal force of the spring rotation. Exit the discharge port and enter the hopper. The feeding device has a simple structure and is suitable for conveying pellets and powders, and is convenient for operation and maintenance.
