Because the air pressure or oil pressure is too low, the automatic screen changing device of the rubber extruder will be slow or even ineffective. In addition, the air leakage and oil leakage of the cylinder and hydraulic station will also cause this problem. Faced with this kind of problem, the operator needs to check the sealing condition of the power system of the screen changer and the air or hydraulic cylinder to avoid the recurrence of this kind of problem.
In the case where the torque of the extrusion system of the rubber extruder is too large and the connection between the main motor and the input bearing is not concentric, the safety pin or safety mechanism of the rubber extruder may be cut off. When this problem occurs, First, check the preheating heating time and observe whether the heating value meets the requirements. Secondly, it is necessary to check the extrusion system to observe whether the screw is stuck by metal or other objects.
In the daily work of the rubber extruder, sometimes there is a sudden drop in the extrusion volume. If this happens, the feeding system may be faulty, or there may be no material in the hopper. If For this reason, it is necessary to carefully check the feeding system to find out the problem, or fill in the appropriate material; in addition, this kind of problem will also occur if the screw is stuck, which requires the extrusion system to be checked and clean up.
During the operation of the rubber extruder, if the feeding is not uniform, the current of the main machine will be unstable, and the bearing of the main motor will be damaged or poorly lubricated; a certain section of the heater fails and does not heat; the screw adjustment pad is incorrect, or the phase is incorrect. It will cause this situation to happen, so it is necessary to check the feeder, main motor and heater frequently to prevent this situation from happening.
In daily work, mechanical equipment will inevitably have some failures, and in order to reduce the incidence of these failures, it is necessary for staff to conduct regular inspection and maintenance, so that these mechanical equipment can work smoothly.
