PVC sheet production line

Introduction to PVC Board Production Line

PVC sheets have high strength, good temperature resistance, and excellent corrosion resistance. Adding additives can increase strength, toughness, hardness, flame retardancy, and printing requirements.

1. Application areas of PVC sheet production line: packaging, printing, stationery, art products, etc. The main products include: gift bags, advertising bags, document bags, lampshades, food packaging, etc.

2. Specification of PVC plastic sheet: thickness: 0.2-30mm, width: 700-2100mm

3. The PVC sheet production line includes: twin-screw extruder, screen changing device, mold, three roll calender, temperature controller, cooling conveyor, traction machine, cutting machine, and coiling machine.

4. Optional equipment for PVC sheet production line: hydraulic metering pump, laminating machine.

5. Purpose and characteristics of PVC board production line: The screw adopts a special mixing function and high-speed design, which ensures the melting of plastic, uniform color, and increased extrusion capacity. The hanger type die adopts a special double section flow design, which makes the adjustment of the thickness of the board more precise.

Temperature control of ± 1 degree can accurately control the plasticization process and the thickness and flatness of the board. The three roll water press adopts a horizontal vertical or 45 ° inclined type, which can be freely lifted and lowered to provide more choices in the operation of thick and thin plates, and improve the quality of the plates. The thickness control of the sheet metal adopts screw adjustment and bi-directional adjustment of the hydraulic pressure wheel to accurately control the thickness ratio of the sheet metal.

The independently controlled roller temperature control system can accurately control the temperature of the pressure roller to ensure uniform thickness of the sheet. The length and quantity of the slicing machine sheet are precise.

The winding table device adopts advanced torque motors, which can adjust the speed and winding tension freely to achieve the purpose of flat sheet winding. Combined with the slitting device, the required product width can be freely set. The machine is equipped with an automatic meter, which can set the product length.

Components of sheet extruder:

1. Extruder system: The screw design conforms to the process characteristics, with a large extrusion volume, uniform material shearing, and high extrusion efficiency.

2. Mold system: Adopting a specialized flow channel structure for skinning foam board, the material is extruded and foamed evenly.

3. Cooling and shaping system: adopting a pressure plate structure and controlled by a hydraulic system, making it easy to control the dimensional accuracy of the sheet metal. The pipeline design of the cooling system makes the cooling of the board more uniform and the shaping faster.

4. Traction cutting system: using a roller type combined traction machine, making the measurement and adjustment of traction force simple. The roller traction machine and the wide cutting machine are electrically synchronized and controlled, making the cutting edge of the sheet flat. The entire production line has a beautiful appearance and easy electrical operation. The produced board has high foaming ratio, high surface hardness, and a smooth and wear-resistant surface.

Production process of sheet metal extruder:

Ingredients - High cold mixing - Extrusion foaming - Cooling and shaping - Spraying - Traction cutting - Stacking - Inspection - Finished product storage
