The knotless extruder is mainly composed of an extruder and an extrusion die. Its working principle is to melt, plasticize and extrude plastic particles to form a continuous plastic belt, which is then stretched into a mesh shape through a special structure in the extrusion die.
Operation skills:
1.Adjust the feeding system: First, adjust the feeding system to ensure that the plastic particles can enter the extruder evenly from the feeding port. The feeding system includes equipment such as a feeder, a feeder, and a feeding controller, which must be adjusted according to the characteristics of the plastic particles.
2. Adjust the extruder temperature: The extruder has multiple heating zones, and the temperature needs to be adjusted according to the melting point and melting temperature range of the plastic. Generally, the melting point of plastic increases with the distance from the heating area, so make sure the heating temperature is gradually increased to keep the plastic in a molten state.
3.Adjust extruder pressure and speed: The pressure and speed of the extruder have a great impact on the mesh size and shape of the final product. Generally speaking, increasing the pressure and rotational speed will make the mesh smaller, while decreasing the pressure and rotational speed will make the mesh larger. Operation needs to be adjusted according to actual needs.
4.Adjust the stretching and winding of the extruder: The extruded plastic belt needs to be stretched and wound to form a continuous knot-free network. The stretching process is usually completed through transmission devices or rollers, while winding requires the use of a winding device. It is necessary to ensure that the speed and tension of stretching and winding are appropriate to ensure the uniformity and stability of the mesh.
5.Maintain and clean the extruder: Regular maintenance and cleaning of the extruder are important steps to ensure its normal operation and extend its service life. Maintenance work includes cleaning machine surfaces and feed systems, replacing worn parts, checking heating elements, etc.
Summarize
The principle of the knotless mesh extruder is to melt, plasticize and extrud plastic particles, and then stretch them into a mesh shape through a special extrusion die. During operation, the feeding system, extruder temperature, pressure and rotation speed need to be adjusted, and stretching and winding required. At the same time, regular maintenance and cleaning of the extruder is also necessary.
