According to the operation process of the extruder unit, it is as follows:<br>1. Before the machine is started, the clothes shall be dressed in order, and the labor protection shall be well worn. It is forbidden to tie the rope around the waist. It is forbidden to wear clothes, shorts and slippers to work;<br>2. Before starting the machine, check whether there are any sundries at the feeding port. The feeding port shall be covered with a cover plate to prevent sundries from falling into the extruder when off duty;<br>3. Preheat the head, body, mouth shape, core shape and clean the marking line device; preheat the protective equipment to prevent scalding. Close the steam pressure after preheating reaches the process requirements;<br>4. Install and lock the mouth type and core type matching the specification, adjust to the specified position, and ensure the uniform thickness of the tire barrel;<br>5. Turn on the main power supply, check whether the electrical system is normal, the operation control system is sensitive and reliable, turn on the oil pump, check whether the oil pump works normally, whether the lubricating oil is smooth, and listen to whether there is abnormal sound at the operation part;<br>6. Start the main engine, turn on all cooling water of the head, fuselage, small roller and screw, and then feed the rubber;<br>7. When feeding, the feed port is blocked. It is forbidden to reach into the feed port to grab the material, or poke it with a stick, and put the rubber material in again;<br>8. After extrusion, it is forbidden to stand at the opposite side of the head to prevent it from popping out when the head is not locked;<br>9. It is strictly prohibited to transfer objects above the running roller, and it is strictly prohibited to rely on, cross over or stand on the running parts of the equipment;<br>10. When adjusting the head bolt, pay attention to check whether there are people around, and use appropriate force to prevent excessive slipping and falling or hurting others;<br>11. When the machine is shut down, turn off the duster and the main engine first, and then turn off the conveyor belt after all the tubes are collected;<br>12. when the extruder is shut down to change the mouth type and core type, two people shall cooperate to prevent foot injury or equipment damage when the mouth type is applied;<br>13. When the machine is shut down and started, the main engine shall be started slowly first, and then it shall be started to the specified speed after the main engine is fully running, so as to prevent the equipment from being damaged due to too fast starting;<br>14. At the end of the work, remove the head, empty the remaining glue in the extruder, clean up the waste, keep the machine clean and tidy, and do a good job in site sanitation after turning off the water, electricity and wind.<br>
