The production of pipe extrusion machines is mainly used for the production of agricultural water supply and drainage, building water supply and drainage, electricity, laying communication cables and other aspects, as well as plastic PVC pipes with various pipe diameters and wall thicknesses.
What are the components of a pipe extrusion machine?
What is the function of pipe extrusion machine?
What are the precautions for using a pipe extrusion machine?
The pipe extrusion machine unit is composed of conical twin screw extruder, vacuum adjusting table, tractor, cutting machine, turning frame, etc. The worm extruder and tractor use AC frequency conversion speed control device, and the vacuum pump and traction motor are all high quality products. The traction machine has two-claw, three-claw and other traction methods. Saw blade type or planet type selectable, length counter and thickening device are also available. The device has reliable performance and high production efficiency.
1. Mixing the raw material is to add PVC stabilizer, plasticizer, antioxidant and other excipients proportionally, and process successively into the high-speed mixer, by the material and mechanical self-friction, the material is heated to the set process temperature, and then the material is lowered by the cold mixer. to 40-50 degrees so that it can be put into the hopper of the extruder.
2. The pipe extrusion machine is equipped with quantitative feeding device, so that the extrusion quantity and feeding quantity can be matched to ensure stable extrusion of the product. Due to the characteristics of the conical screw, the feed area has a larger diameter, and the heat transfer surface and shear speed of the material are relatively large, which benefits the plasticization of the material. Melts can be extruded at lower temperatures. When the screw rotates in the pipe extrusion machine, the PVC mixture is plasticized and pressed to the machine head to achieve the purpose of compacting, melting, mixing and homogenizing, as well as suction and dewatering. The feeder and screw drive unit adopt frequency conversion speed control to realize synchronous speed control.
1. Before opening the pipe extrusion machine, do good hygiene work around the equipment, and do not stack items unrelated to production around the equipment.
2. Before production, check whether the safety settings of the pipe extrusion machine are damaged and whether the test can work effectively. Check that each connecting screw is loose and that each guard is firmly seated.
3. Check all lubricating parts, remove dirt and add lubricating oil.
4. The heating and constant temperature time of the cylinder and mold must be guaranteed, and production will be strictly prevented if the material temperature cannot meet the process requirements.
At the beginning of the new century, YaTong People will continue to adhere to the business credo "boat trend, attentive service", the company's operating philosophy is "using the most advanced scientific technology and manufacturing methods to provide customers with the most suitable machinery and equipment".
