55KW Extruder Power Plastic Sheet Production Line Double Screw Design

Plastic twin screw extruder PVC roofing sheet production line with cutter

Layout:

Crusher (crushing the edge of board trimmed) → Miller (milling the scraps into powder) → Mixer (mixing the main materials and additives) → SJSZ 80/156 conical double Screws Extruder → Mould → Lamination unit → Three-calender unit → Cooling Bracket → Hual-off Machine → Edge Cutting → Cutter → Stacker → UV coating machine(choose need or not)

Application:

PVC sheet production line can continuously produce PVC single-layer and multi-layer sheet products. The sheet has a width of 2000 mm or less and a thickness of 0.15-3 mm.

Features of PVC sheet production line:

A1. Extruder: According to different materials, single-screw, parallel twin-screw and conical twin-screw extruders (exhaust, no exhaust) are used. The screw adopts special mixing function and high plasticizing capacity to ensure the plasticization of the rubber and stable high output.
A2. Changing the net and mold: The hydraulic quick change ensures that the net change does not leak, and the change of the net is fast and effective. The mold selects different structural forms according to different materials. The coat-type die is often designed with a special double-throttle design to make the thickness adjustment of the plate more precise. Various types of hydraulic one-way screen changer, two-way screen changer, and non-stop dual-flow screen changer are available. And through the straight high-efficiency static mixer, the melt output metering pump ensures the smooth extrusion of materials.

A3. Three-roll calender: According to the thickness of the plate (sheet), it is horizontal, vertical or 45° inclined. It can be hydraulic and mechanical. The gap adjustment is convenient, ensuring uniform thickness and calendering effect.

A4. Cooling roller bracket: The corresponding cooling guide roller is equipped for better cooling effect. It is also equipped with a trimming device to ensure the wide material of the plate (sheet).

A5. Transverse cutting machine: used for length cutting, cutting precision less than 2mm, using alloy blade or carbide saw blade, synchronous with the plate (sheet) when cutting. Ensure that the quality of the cut surface of the sheet (sheet) and the cutting action are stable for a long time.

A6. Winding device: The soft board (sheet) with a thickness of 3mm or less is generally wound by friction, and adopts a high-torque motor. It can adjust the speed and tension at will. With the slitting and automatic speed measuring device, the required products can be accurately set. Width and length.
