No matter what kind of machinery, long operation time will produce heat, high thermal energy will affect the life of the machine. Of course, the glass fiber pelletizer hob is the same. The hob of the pelletizer is used for plastic cutting. Compared with other cutting industries, the workload of the hob of the glass fiber pelletizer is higher. So, how can companies protect the life of plastic pelletizer hob without affecting output?

 

Precautions in pelletizer hob operation

 

1. When the pelletizer hob is working normally, its water temperature should generally be around 5060 ℃. If the water temperature is low, it is easy to break the strip and exceed the adhesion. It is better to add half of the hot water when starting the machine. If there is no condition, it can be manually transported to the pelletizer for a period of time during pelletizing, and then it can be automatically pelletized after the water temperature rises to avoid breaking. After the water temperature exceeds 60 ℃, cold water needs to be added to the internal circulation to maintain the temperature.

 

2. When the hob of the pelletizer is centered, the center line of the hob coincides with the center line of the tooth blank, the cutting edges on the left and right sides of the hob tooth groove are symmetrical with the cutting points M1 and M2 of the tooth blank, and the intersection point P1 of the meshing line is on the center line of the hob and the tooth blank. At this time, the tangent points forming the edge are symmetrically distributed on the left and right side of the tooth end face, and the edge value DH corresponding to the left and right side of the tooth profile is completely phase and symmetrical.

 

3. When the glass fiber pelletizer hob is pelletizing, the strips must be pulled to the mixing roller, otherwise the pelletizer will be damaged.

 

4. The hob of the glass fiber pelletizer must be kept clean, and the unpainted part should be coated with anti-rust grease to avoid rust and oxidation.
