The pp hollow sheet extrusion line is an equipment assembled from a series of components, with a total length of about 25 meters and a width determined by the specific model of the equipment. The required placement space for the entire production line is at least 200 square meters. The hollow board production line adopts extrusion molding technology, and its operating process is as follows:

1. Feeding machine: The raw materials (usually plastic particles) are fed into the extruder through the feeding machine.

2. Extruder: The raw materials are heated and melted in the extruder, and then extruded out through the screw of the extruder to form the initial shape of the hollow plate.

3. Screen changer: The extruded molten material is filtered through the screen changer to ensure the uniformity of the extruded material.

4. Mold: The extruded molten material is molded through a mold to form the shape and structure of a hollow board.

5. Setting table: On the setting table, the hollow plate is cooled and shaped to maintain the desired shape and size.

6. Tractor: The standardized hollow plate is stretched through the traction machine to further enhance the strength and stability of the hollow plate.

7. Heat treatment drying channel: Hollow plates undergo heat treatment drying channels to make their internal structure more stable and eliminate internal stress.

8. Cooling machine: The hollow plate is cooled by a cooling machine to ensure that its surface temperature is suitable and ready for subsequent treatment.

9. Traction and cutting: The hollow board is stretched by a traction machine and then cut into the required size hollow board through a cutting machine.

10. Stacking: Stack the cut hollow boards neatly and prepare for packaging and transportation.

The operation process of the entire hollow board production line is a continuous process, and each link plays an important role in ensuring the production of high-quality and stable hollow board products. Through extrusion molding technology, the hollow board production line can efficiently and automatically produce various specifications and shapes of hollow boards to meet the needs of different fields.

The pp hollow sheet extrusion line is usually an automated production line that requires a small number of operators during its operation. The specific number of operators required depends on factors such as the scale of the production line, degree of automation, and production efficiency. Generally speaking, the plastic hollow grid board production line needs to be equipped with the following operators:

1. Extruder operator: responsible for monitoring and adjusting the operating status of the extruder to ensure the smooth extrusion process, requiring certain mechanical operation and equipment adjustment skills.

2. Mold Debugger: Responsible for debugging and adjusting the mold to ensure that the molding effect of the hollow grid plate meets the requirements, and requires certain experience and skills in mold debugging.

3. Quality inspector: Responsible for conducting quality inspection on the produced hollow grid board to ensure that the product meets standard requirements, and requires certain quality inspection skills and experience.

4. Maintenance personnel: Responsible for regular maintenance of production line equipment to ensure its normal operation, requiring certain mechanical repair skills.

If the above four types of operators are put into specific practical applications, only two may be needed, that is, one operator is responsible for extruder and template debugging, and the other operator is responsible for plate connection, quality inspection, and maintenance. Therefore, the number of operators required for the plastic hollow board production line is not fixed, and needs to be adjusted according to the actual production scale and efficiency, mainly to meet normal production needs.

The configuration of machines can be CUSTOMIZED according to your needs!
