Description

Technical Field

[0001] The utility model relates to the technical field of PVC sheet production, and more specifically to a pipe material feeding mechanism and a PVC sheet production system. Background Art

[0002] PVC-U drainage pipe series products connect the drainage pipe network system of the entire civil engineering, carrying the task of conveying and treating sewage, and its importance is self-evident. As a mainstream drainage material, PVC-U drainage pipe has many advantages and characteristics, such as excellent corrosion resistance, high strength and rigidity, excellent sealing performance, light weight and convenient installation, good environmental protection and recyclability. These advantages enable it to better meet the needs of the drainage system of civil engineering and ensure the normal operation and maintenance of the drainage system.

[0003] When manufacturing PVC-U drainage pipe series products, the following process steps are usually followed: 1. Raw material feeding: First, put the PVC-U raw material into the hopper or raw material bin for subsequent processing. 2. Intelligent mixing and feeding: Use an intelligent batching machine to mix different proportions of PVC-U raw materials, additives, stabilizers, lubricants, etc. evenly to ensure the stability of product quality and performance. 3. Raw material extrusion: The mixed raw materials are fed into the extrusion screw through the extruder, and the screw rotates to heat and compress the raw materials, making them viscous and extrudable. 4. Mold forming: The heated and compressed raw materials are extruded into the mold through the extruder to form the shape of the initial pipe. 5. Cooling and shaping: The extruded pipe in the mold passes through the cooling device to quickly cool it down and shape it to ensure the stability of the size and geometry of the pipe. 6. Pipe traction: The pipe after cooling and shaping is pulled at a constant speed through the traction mechanism to maintain the straightness and dimensional stability of the pipe. 7. Cutting machine: The pulled pipe enters the cutting machine and is automatically or manually cut according to the required length. 8. Finished product packaging and off-line: The cut pipes are sent to the packaging machine in an orderly manner through conveyor belts and other devices for packaging and labeling, and finally the finished products are off-line.

[0004] At present, most drainage pipe manufacturers cut the drainage pipes one by one manually, which is inefficient and has the problem of inaccurate cutting due to human factors. Therefore, we need a new drainage pipe cutting mechanism to solve these problems and improve production efficiency and cutting accuracy. Utility Model Content
