①The rubber extruder machine head should be assembled together and installed on the extruder as a whole.
②Before assembling the machine head, wipe off the grease applied during storage, carefully check the cavity surface for bruises, scratches, and rust spots, perform necessary polishing, and then apply a layer of silicone oil on the surface of the runner.
③Assemble the plates of the machine head in order, apply high temperature grease to the threads of the bolts, and then screw on the bolts and flanges.
④ Put the perforated plate between the flanges of the machine head to ensure that the perforated plate is pressed tightly without overflow.
⑤The horizontal position of the die should be adjusted before the fastening bolts of the connecting flange between the die head and the extruder are not tightened. The square die head can be adjusted horizontally, and the round die head should be based on the bottom surface of the finalized model. The bottom of the mold is leveled.
⑥Tighten the connecting flange bolts, tighten the machine head fastening bolts, install the heating ring and thermocouple, pay attention to the heating ring to be close to the outer surface of the machine head.
⑦Install the sizing sleeve and adjust it in place, check whether the center line of the main engine, the sizing sleeve and the tractor are aligned. After adjustment, tighten the fixing bolts. Connect the water pipes and vacuum tubes of the sizing sleeve.
⑧Turn on the heating power supply to evenly heat up the machine head and cylinder. At the same time, open the cooling water at the bottom of the hopper and the gear box and the inlet valve of the exhaust vacuum pump. When heating, the temperature of each section is first adjusted to 140℃, and the temperature is kept for 30-40min when the temperature rises to 140℃, and then the temperature is raised to the temperature during normal production.
