Plastic Sheet Extrusion Machine
Single-layer or multi-layer co-extruded board/sheet extrusion production line include single/twin screw extruder, three-roll calender, shaping device, cooling rack, tractor, shearing machine, sawing machine, stacker and Winding machine, and various related parts such as: mirror roller, embossing roller, screw, barrel, scrap recycling device and conveyor, etc.
1.The plastic sheet(board) extrusion machines adopts high-efficiency, double-mixing bimetallic separable screw, the material is 38CrMOA1A high-quality nitrided steel, and it is nitrided and the surface is sprayed with alloy. With excellent plasticizing and mixing capabilities, it is especially suitable for the production of high-end sheets.
2.
3.The reduction box body is made of steel castings, the gears are made of alloy steel and have been ground teeth. The lubrication points in the box body are all forced to lubricate, and the lubricating oil is equipped with an efficient water cooling system.
3. The three-roller adopts horizontal installation, the movable frame can produce different surfaces of sheets without changing the position of the roller, shortening the time for changing the roller.
4. The calendering roller is independently driven by frequency conversion and speed regulation. The roller adopts 45# seamless steel pipe through special process treatment. It is specially equipped with automatic water supply and temperature control device to greatly reduce the roller surface gradient, so that the sheet surface pattern is clear, smooth and flat without warping.
5. The unit can not only produce (micro-foam) sheet materials used in luggage, handbags, golf accessories and other manufacturing, packaging, stationery manufacturing, etc., but also can produce PE foam hat brim with a little stereotyped bay arc device. , The compatibility of the unit is improved, the enterprise reduces repeated investment, and the market is wider.
Purpose: This production line is mainly suitable for the production of PP, PS, PE, ABS and other materials. The die head of the main machine is replaced. It can also be used for the processing of PVC, PMMA, and PC plates. After installing auxiliary equipment such as drying, that is Can be processed for PET.
