PC and PMMA sheet extrusion production line

Production Line Introduction: This production line is capable of continuous productionPP、PE、PVC、PMMA、PC、PS、PETSingle layer and multi-layer board (sheet) products. The width of board (sheet) products is3000mmAnd below, the thickness of the sheet is0.20-3mm, board thickness20-200mm.

Detailed features

1.Extruder: Select (exhaust) according to different materials，Non exhaust single screw, parallel twin-screw, and conical twin-screw extruders. The screw adopts special mixing function and high plasticizing ability design,Ensure good plasticization and stable high-yield extrusion of the rubber material.
2.Mesh replacement and mold: Hydraulic quick change ensures no material leakage during mesh replacement, and mesh replacement is fast and effective. Different structural forms of molds are selected according to different materials. We often use hanger type molds with special double flow design,Make the thickness adjustment of the board more precise. Multiple forms of hydraulic one-way screen changers can be optionally selected,Bidirectional network converter; And non-stop dual channel screen changer. And it can be ensured that the material is smoothly extruded by using a straight and efficient static mixer and a melt output metering pump.
3.Three roll calender: Depending on the thickness of the board (sheet) material, horizontal, vertical or45°tilting.There are two lifting methods available: hydraulic and mechanical. Convenient gap adjustment ensures uniform thickness and calendering effect.
4.Cooling roller bracket: equipped with corresponding cooling guide rollers for better cooling effect. Equipped with a trimming device to ensure the width of the board (sheet) materialmaterial.
5.Horizontal cutting machine: used for fixed length cutting, with cutting accuracy less than2mm,Use alloy or hard alloy saw blades to cut synchronously with the sheet material. Ensure the quality of the cut surface of the board (sheet) material and the long-term stability of the cutting action.
6.Winding device: generally thick3mmThe following soft boards (sheets) are wound using friction and powered by high torque motors.Can adjust speed and tension freely.Combined with slitting and automatic speed counting devices, the required product width and length can be accurately set.
