Precautions for using pvc profile extrusion

Precautions for using pvc profile extrusion

The precautions for using pvc profile extrusion are as follows:

1. The pvc profile extrusion line should operate in a forward direction to avoid reverse rotation.

2. The pvc profile machine must not operate on an empty stomach with a cooling machine. It must be operated with a hot machine feeding machine to avoid sticking the shaft.

3. It is strictly prohibited to enter impurities such as ironware into the feeding port and vent hole of the pvc pipe machine to avoid accidents and affect production.

4. When operators fill the material, they must keep an eye on it, avoid impurities in the material, and control the temperature properly.

5. If there is a phenomenon of sticking to the mold head when the material does not form a strip when the machine is turned on, it is because the temperature of the mold head is too high. It can be normal after a little cooling, and generally there is no need to shut down the machine.

6. The water temperature should generally be between 50 and 60 ℃. If it is low, it is easy to break the strip, and if it exceeds the limit, it is easy to stick. It is best to add half of the hot water when starting the machine. If there are no conditions, a person can transport it into the cutting machine for a period of time. After the water temperature rises, it can be automatically cut to avoid breaking the strip. After the water temperature exceeds 60 ℃, it is necessary to circulate cold water inward to maintain the temperature.

7. When cutting, it is necessary to evenly pull the strips before entering the mixing roller, otherwise it will damage the cutting machine. If the exhaust hole competes with the outside and emits excessive material, it indicates that impurities have blocked the filter screen. At this time, it is necessary to quickly stop the machine and replace the mesh. The mesh can be selected from 40 to 60 mesh.

Any machine and equipment must be operated and maintained in a standardized manner, and pvc pipe extrusion line are no exception, in order to ensure machine efficiency and extend machine service life.
