The screen changer of plastic granulator is one of the important equipment in the production process of plastic machinery, and its function is to heat, melt and extrude plastic particles into plastic particles of a certain shape to meet the needs of the subsequent production process. However, during long-term use, the screen changer of the plastic pelletizing machine will be subject to problems such as wear or clogging, and needs to be replaced or cleaned. This article will introduce the screen changing process of the plastic pelletizing machine screen changer in detail to help users better maintain and use the equipment.
1. Preparations.
Before you start changing the screen, you need to make the following preparations:
1.Confirm the model and specification of the mesh that needs to be replaced to ensure that the selected mesh meets the equipment requirements.
2.Check that the area around the screen changer is clean to ensure that there is no interference from impurities or dust during the screen changing process.
3.Prepare the tools and materials you need, such as wrenches, screwdrivers, cleaning agents, etc.
2. Disassemble the old mesh.
When disassembling old mesh, you need to pay attention to the following:
1.Turn off the power of the plastic pelletizing machine to ensure the safety of operation.
2.Loosen the set screws on the screen changer and remove the old mesh.
3.Clean up the residue inside the screen changer to ensure that the new mesh can be installed smoothly.
3. Install the new mesh.
When installing a new mesh, you need to pay attention to the following:
1.Place the new mesh on the screen changer as required, ensuring that the size and shape of the mesh matches the equipment requirements.
2.Use a torque wrench to tighten the set screws on the screen changer according to the specified torque to ensure that the mesh is firmly fixed on the device.
3.Check the mesh for looseness or misalignment and adjust it if necessary.
Fourth, debugging and operation.
After the network change is completed, it is necessary to debug and run to ensure the normal operation of the equipment
1.Turn on the power of the plastic pelletizer, run it with no load, and check whether the screen changer has abnormal sound or vibration.
2.After confirming that the equipment is operating normally, gradually increase the load until the normal production state is reached.
3.Observe the working condition of the screen changer, and adjust and repair it in time if there is a problem.
5. Precautions.
In the process of changing the screen, you need to pay attention to the following points:
1.Keep it clean and hygienic during operation to avoid impurities or dust from entering the inside of the equipment.
2.Select the mesh model and specification that meet the requirements of the equipment to ensure the normal operation and service life of the equipment.
3.When installing a new mesh, make sure that the mesh is positioned and oriented correctly to avoid unnecessary losses.
4.In the process of commissioning and operation, if abnormal conditions or sounds are found, it is necessary to stop the machine for inspection and maintenance in time.
5.It is recommended to use professional tools and materials during operation to ensure the smooth progress of the screen changing process and the normal operation of the equipment.
In a word, the screen changing process of the plastic pelletizer needs to be carried out carefully and carefully to ensure the normal operation and service life of the equipment. The user should follow the regulations and requirements of the equipment during operation to avoid errors or abnormal situations. If you encounter problems or difficulties, you can consult or ask for help from professional and technical personnel in time.
