What should be paid attention to items in use of extruder?
What should be paid attention to when using the screw extrusion extruder? Everyone will have a lot of doubts in the production process. Let's take a look at it. In the normal production process, you should pay attention to those:
1.Infrequently start the main motor of the extruder, the two start intervals must be greater than 15 minutes, otherwise it will easily cause the control cabinet and motor to burn out.
2.The feeding frequency is not lower than 5Hz for a long time, otherwise the inverter and the feeding motor will be burnt.
3. The feeder must be turned on when the main unit rotates normally, otherwise the extruder will become clogged. After the extruder is clogged, the heating coil should be heated first, and after waiting for the burnt smell inside the barrel, the main motor is started to discharge the blocked material when it is determined that the motor can be driven. If it can not be ruled out, open the mold of the discharge port and clean it manually. Otherwise, the barrel of the exit section should be disassembled.
4.Do not bring hard objects such as iron or stone into the extruder, as this will cause damage to the spiral and shear pins. The magnetic separator is randomly installed at the entrance of the extruder, but it is not guaranteed to be trapped under the impact of the material. Therefore, it is necessary to pay attention to removing iron and stone during the pretreatment, and regularly clean the magnetic separator.
5.Do not put the hemp rope and grass stems into the puffing machine. Keep the raw materials clean when mixing. Otherwise, the hemp rope or grass stems will be wrapped around the spiral and the shear pin, which will result in improper feeding and mold. The hole is blocked and affects the yield.
6. Regularly check the lubricating oil level of the bearing housing of the main engine. If it is insufficient, it should be replenished in time. The lubricating oil liquid level should not be lower than 1/2 of the bearing housing, and the lubricating oil should be replaced in time according to the requirements, otherwise the bearing will be damaged.
7.Improper selection of cutting blades can easily lead to shortened service life of slitting blades, which can not meet the requirements of cutting index. The products that are cut will produce a large number of non-conforming products, which will affect the output of the products.
