The plastic pellet extruder has high output, the heating system can achieve an energy saving rate of up to 30% to 50%, and the energy saving effect is excellent, and the installation of a deodorant and smoke exhaust system is more environmentally friendly.
How to deal with the different sizes of plastic pellet extruder products?
What are the common problems of plastic pellet extruder and how to deal with them?
How to control the pressure of plastic pellet extruder?
1. check the plastic pellet extruder's melt pressure, melt temperature, vacuum pressure, water pump, and oil pump level.
2. Check the filter screen of the plastic pellet extruder to see if there is any debris on it. If it needs to be replaced immediately, it will not affect the product quality.
3. Check the perforated plate in the plastic pellet extruder, and remove the material on the surface. If it is severely corroded or the hole is blocked, it needs to be replaced immediately.
4. If the above methods cannot be solved, it is recommended to use iron wire to dredge the holes on the template that do not produce material. If it still does not work, replace the template and clean up the carbonized material inside.
Whether the pressure of the plastic pellet extruder head is unstable and the lubricating oil pressure is low, the operation steps are as follows:
1. Reasons for the unstable pressure of the plastic pellet extruder head: the main motor rotates unevenly; the feeding motor rotates unevenly, and the feeding amount fluctuates.
The processing method is:
Check the main motor control system and bearings; check the feeding system motor and control system.
2. Causes of low lubricating oil pressure: The pressure setting value of the pressure regulating valve of the lubricating oil system is too low; the oil pump is faulty or the oil suction pipe is blocked.
The processing method is:
Check and adjust the pressure regulating valve of the lubricating oil system of the plastic pellet extruder; check the oil pump and oil suction pipe.
In order to reflect the extrusion situation of the head of the plastic pellet extruder, it is necessary to detect the head pressure during extrusion. Generally, the measurement of the thrust after the screw extrusion replaces the measurement of the head pressure. The screw load meter (ammeter or voltmeter) can correctly reflect the size of extrusion pressure. The fluctuation of extrusion pressure is also one of the important factors that cause unstable extrusion quality. The fluctuation of extrusion pressure is closely related to factors such as extrusion temperature, the use of cooling device, and the length of continuous operation time. When an abnormal phenomenon occurs in the plastic pellet extruder, those that can be eliminated quickly, and those that must be reorganized should be stopped decisively, which can not only avoid the increase of waste products, but also prevent the occurrence of accidents.
