PE, PP, PS, PVC sheet production line
PE, PP, PS, PVC sheet production line can be used to continuous produce PP, PE, ABS, PMMA, PC, PS, PVC single layer and multilayer sheets. Sheet width at 2000mm and below, the thickness of 0.15-3mm. Extruder: according to different materials, select (non-degassing, venting type) single screw extruder, screw adopting special mixing function and precise temperature control system ensures the high plasticizing, high capacity and stable plastic extrusion. Temperature control is within ± 1 ℃, which can control plasticization process and sheet thickness & flatness in accuracy. Screen changer and die: fast screen changing device ensures no leakage, fast and effective screen changing; mould choosing different structure form according to different material, coat hanger die adopt page double throttle design, easy to adjust the flow distribution, the adjustment of sheet thickness is more accurate. Three roller calender: according to the sheet thickness, 45 ° tilt type three roller or vertical three roller or horizontal three roll calendar can be adopted, special design of independent control for three roller temperature, free adjustment for roller gap, angle adjustment for middle roller, ensure the calendering effect and thickness uniformity.
Sheet thickness control uses screw adjustment and pressing wheel two-way adjustment, which can accurately control sheet thickness. Independent control of roller temperature control system can precisely control the temperature of the roller to ensure sheet thickness uniformity. Cooling roller bracket: equipped with corresponding cooling roller, the cooling effect is better, and equipped with edge cutting device, ensures the sheet setting width and edge quality. Horizontal cutting machine: for length cutting, cutting precision is less than 2mm, use alloy blade or hard alloy saw blade, cutting moves synchronous with sheet, so as to ensure the quality of sheet cutting section and the long-term stable cutting action. Winding machine: high torque motor, friction rewinding, can adjust speed and winding tension, we can also provide other forms of winding according to the customer’s need.
