Description

Technical Field

[0001] The utility model relates to the technical field of plastic product cooling and forming devices, and particularly relates to a cooling and forming device for manufacturing plastic products. Background Art

[0002] Plastic is a high molecular compound polymerized from monomers through addition polymerization or polycondensation reaction. Its anti-deformation ability is medium, between that of fibers and rubber, and it is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. An extruder is the most commonly used processing equipment for plastic products. When plastic pipe products are extruded from the extruder, they have a high temperature and are soft, so it is necessary to cool and form the products in time.

[0003] At present, the cooling and forming device usually uses the method of cooling water spraying to cool the just-extruded plastic pipe products. However, due to the continuous extrusion of the products, the plastic pipe products after being cooled by the cooling water spraying still have a high temperature, and there will be water droplets remaining on the surface of the plastic pipe products after being cooled by spraying, which will affect the subsequent packaging work. Therefore, a cooling and forming device for manufacturing plastic products is provided to solve the above problems. Content of the Utility Model
