Description

Technical Field

[0001] The utility model relates to the technical field of plastic product processing, in particular to a processing cooling device for plastic products. Background Art

[0002] During the processing of plastics, they will experience high-temperature melting and plastic deformation. These processes will cause a large amount of heat to be generated inside the material. If this heat is not dissipated in time, it may cause thermal deformation, surface roughness, uneven shrinkage and other undesirable phenomena in the products. Therefore, cooling can effectively reduce the temperature of the products and restore the plastics to a relatively stable solid structure, ensuring that the shape and size of the products meet the design requirements.

[0003] There is a plastic product processing cooling equipment, which mainly uses a coolant with a density greater than that of the plastic product to cool the plastic product. Since the coolant has a density greater than that of the plastic product, the plastic product floats on the liquid surface. The equipment first uses a pushing device to push the plastic product placed in the coolant into a linear groove, and drives the plastic product to slowly push it to the bottom of the recovery port. When the plastic product comes to the bottom of the recovery port, it will float up quickly, and then the plastic product will be recycled. The equipment cools the plastic product by coolant, eliminates the internal stress of the plastic product, and utilizes buoyancy to facilitate the recycling of the plastic product.

[0004] However, those skilled in the art have discovered that the cooling device still has certain defects: since the plastic products need to be pushed to the bottom of the coolant by a pushing device, new plastic products cannot be added during the cooling process of one plastic product, which results in a long cooling interval between two plastic products and low processing efficiency. In addition, in order to prevent the plastics from being squeezed and damaged during the pushing process, the amount of plastic products added at a time is low. Therefore, those skilled in the art have proposed a processing cooling device for plastic products to solve the above-mentioned problems. Utility Model Content
