Friends in the industry should know that among the plastic extrusion machinery and equipment, the plastic extrusion machinery is often called the main machine, and the supporting plastic extrusion molding machine is called the auxiliary machine. After more than 100 years of development, plastic extrusion machinery has been derived from the original single screw into a variety of models, such as twin screw, multi screw, or even no screw. The plastic extrusion machine (main machine) can be used together with various plastic forming auxiliary machines such as pipe, film, clamping material, monofilament, flat filament, packaging belt, extrusion net, plate (sheet), profile, granulation, cable coating, etc., Forming a variety of plastic extrusion production lines to produce various plastic products. Therefore, whether now or in the future, pipe extrusion machinery is one of the widely used machinery in the plastic processing industry.
1. the mechanical equipment of the plastic pipe extrusion machine shall be placed in a ventilated position to ensure the heat dissipation of the motor and prolong its service life; This machine should be well grounded.
2. regularly check the tool screws. After the new machine is used for 1 hour, use tools to tighten the screws of the moving knife and the fixed knife to strengthen the fixity of the blade and the tool holder; The bearing shall be regularly lubricated to ensure the lubricity between bearings; In order to ensure the sharpness of the tool, the tool should be checked frequently to ensure its sharpness and reduce unnecessary damage to other parts caused by blunt blades; Regularly check whether the belt is loose and tighten it in time.
3. restart - before the second startup, remove the remaining debris in the machine room to reduce the startup resistance. The inertia cover and pulley cover shall be opened regularly, and the ash outlet under the flange shall be removed, because the powder discharged from the crusher room enters the bearing shaft.
4. replacement of parts - when replacing the cutter, the gap between the crusher motor cutter and the fixed cutter above 20HP is better, and the crusher below 20HP is better. The thinner the recycled material is, the larger the gap can be properly adjusted.
