How should the pelletizer be maintained? – Suzhou Polytime Machinery Co., Ltd.

The scale of China's plastic enterprises is becoming larger and larger, but the recovery rate of waste plastics in China is not high, so the plastic pelletizer equipment has a large number of customer groups and business opportunities in China, especially the research and development of waste plastic recycling pelletizer and other equipment in life has a wide development space.

What is the process flow of the pelletizer?
The pelletizer has a complete process flow. Firstly, the raw materials are selected and classified by the automatic classification system, and then the raw materials are crushed and cleaned. Next, the automatic feeding machine puts the cleaned raw materials into the main machine for plasticization, and the auxiliary machine extrudes the plasticized raw materials and cools them by water or air. Finally, the bag is loaded after automatic granulation according to the specified parameters.

How should the pelletizer be maintained?
1. It is forbidden to start and shut down the motor frequently.

2. Start another motor only after the motor is fully started and runs stably, so as not to trip the power circuit breaker.

3. During electrical maintenance, the power supply must be cut off before opening the shell of explosion-proof devices.

4. When the machine is not in use, it should be in the emergency stop state. After all the machines are shut down, press the "emergency stop" button. When restarting, it is necessary to release this button first. However, do not use this button for normal shutdown operations.

5. The motor shall be inspected and cleaned regularly. The shell shall not accumulate dust. It is strictly prohibited to spray water to clean the motor. During machine maintenance, the bearing grease shall be replaced in time and high-temperature grease shall be replaced.

6. The electric control cabinet and field operation console and each motor shell must be protected and grounded.

7. If the continuous power failure time of the equipment exceeds 190h, carefully check whether the parameters such as cutting length, feeding speed, and clock calendar meet the use requirements before granulation production, and reset them if necessary.

8. If the rotation direction of the motor is found to be inconsistent during the initial use, open the corresponding motor junction box after power failure and transpose any two power lines.

9. The adjustable parameters of the equipment shall be set correctly according to the actual situation. Users of other components shall not adjust or change at will.

What points should be paid attention to when using plastic pelletizer?
Control the stability of casting head discharge, temperature, and viscosity in production. According to the production load, the temperature and flow of pelletizing water shall be adjusted in time to keep the casting strip temperature and cooling water temperature appropriate during pelletizing, to ensure the good pelletizing effect of the pelletizer and avoid abnormal chips and dust during cutting as far as possible. In the early stage of use, the knife edge is sharp, and the water temperature can be adjusted appropriately. After a certain period of use, the knife-edge becomes blunt and the water temperature should be slightly lower. During the maintenance and assembly of the pelletizer, not only the cutting clearance of the fixed cutter and the hob shall be carefully adjusted to ensure that it is controlled within the allowable range, but also the radial runout of the hob during high-speed rotation shall be eliminated.

Correct and reasonable operation of the pelletizer is the key to ensure the smooth operation of the pelletizer. At the same time, it is also one of the important guarantee means to maintain the smooth operation of production and the appearance quality of slices. Stable production can ensure product quality.
