Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipe production, in particular to a supporting and unloading rack of a PVC pipe production line. Background Art

[0002] PVC is the abbreviation of polyvinyl chloride, which is mainly composed of polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. PVC pipe (divided into PVC-U pipe, PVC-M pipe and PVC-O pipe) is a rigid polyvinyl chloride pipe, which is made of polyvinyl chloride resin, stabilizer, lubricant, etc. and then extruded by hot pressing. It is the earliest plastic pipe material developed and applied; PVC-U pipe has strong corrosion resistance, easy bonding, low price and hard texture, but due to the leakage of PVC-U monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic pipes are used for drainage, wastewater, chemicals, heating and cooling liquids, food, ultrapure liquids, mud, gas, compressed air and vacuum system applications; PVC-O pipe, Chinese name biaxially oriented polyvinyl chloride, is the latest evolution of PVC pipe. It is a pipe manufactured through a special orientation processing technology. The PVC-U pipe produced by extrusion is stretched axially and radially to make the PVC long-chain molecules in the pipe arranged regularly in the biaxial direction, so as to obtain a new type of PVC pipe with high strength, high toughness, high impact resistance and fatigue resistance.

[0003] The Chinese utility model patent application publication specification CN214643557U discloses a support and unloading rack for a PVC pipe production line. Although the support and unloading rack has the function of separate placement and convenient fixing and management when in use, it still has the following defects: First, each time the PVC pipes are stored, they need to be put in one by one, resulting in low storage efficiency, and the same is true for each unloading, which is time-consuming. Second, the support and unloading rack can only store a small amount at a time. When storing in large quantities, the practicality of the support and unloading rack will be greatly reduced, and the device needs to manually lift the storage component, resulting in more laborious transportation.
