Plastic film granulator die head is one of the key components in plastic processing production, to ensure production quality and efficiency has an important role. Correct use and maintenance of plastic pellet melting machine die head can extend its service life, improve production efficiency, and reduce the failure rate. This article will introduce you to the correct use and maintenance of pellet machine plastic die heads.
Working principle of plastic film granulator die head
Plastic pellet melting machine die head is a device that melts plastic raw materials by heating and then extrudes them through the eyelets of the die head to finally form plastic pellets. In this process, the design and condition of the die head directly affect the quality and output of the finished pellets.
Correct use of pellet machine plastic die head
Material selection
When using plastic film granulator die head, suitable plastic raw materials should be selected according to production needs. Ensure that the raw materials are of good quality and have few impurities to avoid damage to the die head.
Adjustment of process parameters
According to the type of plastic used and the required pellet shape, adjust the temperature, speed and other process parameters of the extruder. Gradually increase the speed of the plastic pellet melting machine and observe the shape and quality of the pellets to ensure that the desired state is gradually reached.
Temperature control
Depending on the type of plastic, set the temperature parameters appropriately. Too high a temperature may cause the plastic to overheat and affect pelletizing quality, while too low a temperature may prevent the plastic from melting completely.
Control of extrusion speed
Appropriate extrusion speed ensures uniformity and quality stability of pellets. Too fast extrusion speed may cause uneven melting of plastic in the die head, or even block the die head, affecting production efficiency. Therefore, the operator should adjust the extrusion speed of the plastic film granulator according to the design parameters of the die head and the plastic characteristics.
Maintenance of plastic pelletizer die head
- Regular cleaning of the die head: During the production process, plastic residues may accumulate inside the die head, affecting the melting and flow of plastic. Therefore, it is necessary to stop the machine periodically to clean the die head. Use special cleaning tools, avoid using sharp objects to scrape the surface of the die head to avoid damage.
- Pay attention to lubrication and maintenance: Some plastic film granulator die heads need to maintain a certain degree of lubrication while working. However, pay attention to the selection of lubricants suitable for plastic materials to avoid incompatible reactions with plastics. Check the lubrication system regularly to ensure proper lubrication.
- Regularly check for wear and damage: The plastic film granulator die head may become worn or damaged over a long period of time, which can affect the flow of the plastic and the quality of the product. Regularly check the die head for wear and replace damaged parts in a timely manner to ensure proper operation of the die head.
- Reasonable storage: In case of downtime or long time unused, the plastic film granulator die head should be properly packed and stored to avoid dust and moisture from entering into the die head and causing unnecessary damage.
