step one, raw material selection: the raw materials comprise polyvinyl chloride and polyvinylidene fluoride resin molding films and sheets;
step two, mixing the raw materials: putting the selected materials into a feeding hopper (23), then starting a first motor (25) under the action of gravity to rotate a screw (26), then mixing the materials, and further dropping the materials onto a rotating wheel (28) and a fixed wheel (29), wherein when the rotating wheel (28) and the fixed wheel (29) are staggered, the mixed materials are extruded out of the extruder (6), the feeding amount can be controlled by adjusting the rotating speed of the first motor (25), and then the thickness of the film is adjusted;
step three, melting raw materials: the mixed material entering the extruder (6) is heated to the temperature of 215-280 ℃, the temperature is gradually increased, the material is heated, melted and plasticized, good plasticization is guaranteed, the pressure of the extruded solution is stable, and then the melted material is filtered to remove impurities, gel ions and other foreign matters possibly existing in the solution;
step four, extrusion molding: firstly, controlling the width and thickness of a formed film, then leading the film extruded from a lip of a die to be drawn by a roller in front of the die, and cooling and shaping the film on the roller; then pressing is continued through a calender roll, and finally, winding can be directly carried out after passing through an edge cutting device;
step five, cooling treatment: the formed film is pulled out from the extruder (6), then a water pump (51) is started, a water source in the workbench main body (1) is pumped through a pumping pipe (52), then is injected into a U-shaped rod (54) from a water injection pipe (53), and then is sprayed on the discharged film through a spray head (55), so that secondary cooling is performed, impurities on the film can be cleaned, cleanness is guaranteed, secondary processing cleaning is reduced, and working efficiency is improved; and the number of the first and second groups,
step six, film packaging: the plastic film with secondary cooling twines cooling shaft (41) earlier, then passes first guide film roller (43) on installation piece (42), then straightens plastic film through second guide film roller (46), then carries on spacingly through limiting plate (45) to plastic film, makes regular winding of plastic film on receiving film roller (48), starts second motor (47) this moment for receive film roller (48) and rotate, roll up the packing with plastic film.
