How to operate the sheet material machine
If it is the first time a sheet material machine is put into use, we should first heat the machine for about 40 or 50 minutes when turning it on. The recommended operating method is to manually pull the triangular belt of the motor until they are free; Pull 8 to 10 times continuously according to the normal working direction, then continue heating for about 10 minutes, and then start. However, due to the need for continuous heat supplementation in normal production, heating should continue; Adjust different temperatures according to the different properties of plastic.

Operation method of sheet material machine:
If it is the first time a sheet material machine is put into use, we should first heat the machine for about 40 or 50 minutes when turning it on. The recommended operating method is to manually pull the triangular belt of the motor until they are free; Pull 8 to 10 times continuously according to the normal working direction, then continue heating for about 10 minutes, and then start. However, due to the need for continuous heat supplementation in normal production, heating should continue; Adjust different temperatures according to the different properties of plastic.
2. When working, ensure that the machine temperature does not fluctuate from high to low.
3. The feeding of the sheet extruder should be uniform and sufficient material should be added. The feeding speed and feeding speed of the sheet extruder will otherwise affect the quality and output of the particles.
4. The power supply of the sheet material machine should be completely cut off when it is stopped from use.
The following are the precautions to be taken when using a sheet machine:
1. From the feeding section to the connection between the machine barrel and the forming mold, the temperature of each section of the sheet material machine barrel varies and gradually increases.
The temperature of the forming mold should be slightly higher than the temperature of the cylinder. In general, the temperature difference should be controlled between 5-10 ℃, and the temperature at both ends of the mold should also be slightly higher than the middle temperature. The temperature difference is the same as before.
3. The height of the three roll intermediate roller is on the same plane as the lower lip of the mold, and the lip end face is parallel to the intermediate roller.
In order to form a uniform thickness of the melt in the mold, the temperature of the forming mold should be maintained at a certain value.
To avoid affecting the thickness of the sheet, the working temperature of the three rollers of the sheet machine should be higher than the speed of the sheet extrusion mold mouth, and the speed should be stable.
