Feeding method of the central feeding system:
1. Fully automatic feeding system equipment:
Using fully automatic air pipeline transportation and loading method , are mostly used in parallel production and supply of materials by several extruders. In such a relatively large-scale extrusion product workshop, the material conveying system consists of a main feeding pipe, and then branches into several branch pipes to feed each Extruder hopper feeding. This method of conveying materials by relying on compressed air and using air ducts has the characteristics of occupying a small area, employing fewer people, and having a relatively clean environment. It can be used to transport granular materials and powder materials to meet the requirements of different workshops.
2. Central feeding system equipment:
When the hopper of the feeding system needs to be loaded, the fan 2 is started and passes through the suction pipe 4 and the filter 3, so that the intermediate storage A negative pressure is formed in the silo; at the same time, the suction pipe 8 connected to the intermediate storage silo and the raw material box sucks the raw materials in the raw material box into the intermediate storage silo. 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 supply the extruder hopper with material to the central system. The central feeding system equipment is composed of a fan, a suction pipe, a storage Silo, suction pipe, filter, electric control box, etc.
3. Spring loading system equipment:
It installs a coil spring in a rubber tube. 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 with materials, starting the motor will drive the spring to rotate, and the raw materials will be spirally driven up by the spring. There will be a discharge port at the upper end of the rubber tube aligned with the hopper, and the raw materials rising to the discharge port will be thrown away by the centrifugal force of the spring rotation. Exit the discharge port and enter the hopper. This kind of feeding device has a simple structure, is suitable for conveying granular materials and powder materials, and is very convenient to operate and maintain.
The above introduction is about several common feeding methods of the central feeding system. The central feeding system is easy to operate.
