The main components of the plastic sheet production line, Main features of extrusion equipment:
Extruder -Quick screen changer -Solution metering pump-Sheet extrusion die-Three-roll calender-Edge trimming device/Cooling and shaping bracket-2 Roller Tractor -Cut-to-length output unloading or rewinding machine
Details of extrusion equipment:
- The models of extruders are: SJ-75 extruder, SJ-90 extruder, SJ-120 extruder, SJ-150 extruder, SJ-180 extruder.
- Quick Screen Changer, The filter mesh of 80-200 mesh can be woven, the pressure can be increased during the extrusion process and the impurities in the raw material can be filtered out.
3. Melt Metering Pump: Control the metering of molten raw materials and even deliver them to the machine head.
4. Plastic Sheet Extrusion Die: the material flows evenly, and can manufacture sheets of different widths and thicknesses.
5. Three-roll calendar: The sheet extruded from the flat head has a high temperature, and is calendered by the three-roll calendar and gradually cooled.
At the same time, it also plays a specific role in traction, adjusting the speed of each point of the board to be consistent to ensure the flatness of the board.
According to the processing performance of different materials, three-roll calendars can be divided into flat three-roll calendars, vertical three-roll calendars, and 45-degree inclined three-roll calendars.
6. 6. (Edge trimming device) Cooling and shaping bracket:
For a plate or sheet extruded from a die, the ends need to be cut off.
Between the three-roll calender and the two-roll tractor, there are 10-20 stainless steel rollers with a diameter of 63 mm for cooling and conveying, so that the plate sheet can naturally dissipate heat in the air.
The length of the cooling bracket is determined according to the thickness of the plate so that the plate is cooled and formed.
7. The 2-roller pulling machine comprises 2 rollers, which evenly pull the tube or sheet to the cutting device.
7. The 2-roller pulling machine comprises 2 rollers, which evenly pull the tube or sheet to the cutting device.
8. Fixed-length cutting and output unloading or rewinding machine: The hard plate or thick plate output by the tractor needs to be cut to a fixed length and conveyed for unloading.
The soft board or sheet output by the tractor needs to be rolled into a cylindrical shape
9. The extrusion production line is equipped with an automatic vacuum feeder or screw feeder
10. Equipped with a drying hopper, the models are: 50KG, 75KG, 100KG, 150KG
