[0002] Plastic pellets, commonly known as plastic granules, are the raw materials used to store, transport, and process plastics into semi-finished products. They are used in various consumer goods, the clothing industry, and building materials, such as plastic bags, buckets, basins, toys, furniture, stationery, pallets, buttons, zippers, plastic doors and windows, and plaster buckets. The plastic pelletizing process involves mixing, followed by extrusion into filaments. The filaments are hot at this stage and require cooling. After cooling, the filaments are dried and pelletized.

[0003] The most common cooling method for plastic shaping is water tank cooling, where the plastic raw materials are directly cooled by contact with cooling water. This method will cause the plastic raw materials to become damp, and a dryer will need to be used to dry the plastic raw materials to prevent the moisture content in the finished plastic particles from exceeding the standard and affecting the quality, thus increasing the production process.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution: a plastic particle shaping cooling device, comprising a water-cooling frame 1, an air-cooling frame 2, a cooling water trough 3 and a reflux water trough 4. The water-cooling frame 1 comprises a frame body 11 and multiple groups of cooling rollers 12. A water supply pipe 13 is provided on one side of the frame body 11, and the water supply pipe 13 is connected to one end of the multiple groups of cooling rollers 12. A reflux pipe 14 is provided on the other side of the frame body 11, and the reflux pipe 14 is connected to the other end of the multiple groups of cooling rollers 12. The cooling water trough 3 and the water supply pipe 13 are connected through a water pump 5 and a conveying pipe 15. A cooling chamber 121 is provided inside the cooling roller 12. The air-cooling frame 2 comprises a mounting frame 21 and a cooling fan 22. The reflux water trough 4 is used to receive reflux cooling water.

[0024] like Figure 3 As shown, the drawn plastic raw material is laid along the multiple groups of cooling rollers 12 of the water-cooled rack 1, and cooling water is stored in the cooling water tank 3. When the water pump 5 is working, the cooling water inside the cooling water tank 3 is extracted and transported through the delivery pipe 15. The cooling water is transported to the water supply pipe 13, and then diverted to the cooling cavity 121 of each cooling roller 12 through the water supply pipe 13. When the cooling water flows inside the cooling cavity 121, heat exchange is realized, and the outer wall of the cooling roller 12 is cooled. The drawn plastic raw material is in close contact with the outer wall of the cooling roller 12 for heat exchange, and the drawn plastic raw material is cooled and shaped through the outer wall of the cooling roller 12.

[0025] When cooling and shaping the plastic raw materials after drawing, the cooling water does not directly contact the raw materials, so it will not cause excess moisture inside the plastic raw materials. Therefore, there is no need to dry the plastic raw materials after cooling and shaping, which simplifies the production process while ensuring the shaping and cooling quality.

[0026] The plastic raw material after drawing is water-cooled by the water-cooling rack 1, and the plastic raw material after drawing is auxiliary-air-cooled by the air-cooling rack 2, so as to further improve the shaping cooling quality and shaping cooling efficiency.

[0027] Among them, multiple groups of cooling rollers 12 are evenly spaced along the straight direction of the frame 11. During the movement of the drawn plastic raw materials, they are in close contact with the multiple groups of cooling rollers 12. The multiple groups of cooling rollers 12 cool the plastic raw materials multiple times, thereby improving the shaping cooling quality of the plastic raw materials.

[0028] The two ends of the cooling roller 12 are connected to the frame 11 via the first bearing 6 . The arrangement of the first bearing 6 enables the cooling roller 12 to rotate relative to the frame 11 .

[0029] Among them, one end of the cooling roller 12 is connected to the water supply pipe 13 through the second bearing 7, and the other end of the cooling roller 12 is connected to the return pipe 14 through the second bearing 7. The setting of the second bearing 7 enables the cooling roller 12 to rotate relative to the water supply pipe 13. The cooling roller 12 can rotate relative to the return pipe 14. During the movement of the plastic raw material after drawing, the friction force drives the cooling roller 12 to rotate. Multiple groups of cooling rollers 12 guide the plastic raw materials while cooling.

[0030] The reflux pipeline 14 is connected to a drain pipe 16 , and one end of the drain pipe 16 extends into the reflux tank 4 .

[0031] During the cooling process, driven by the water pump 5, the cooling water enters the cooling chamber 121 of the cooling roller 12 through the water supply pipe 13. The cooling water after heat exchange is concentrated into the return pipe 14, and then enters the drain pipe 16 through the return pipe 14, and then flows into the reflux water tank 4 through the drain pipe 16. The reflux water tank 4 collects the reflux cooling water and can be put into reuse.

[0032] The mounting frame 21 of the air-cooling frame 2 is mounted and fixed on the frame body 11 of the water-cooling frame 1 .

[0033] The cooling fan 22 is mounted on the water cooling rack 1 , and the plastic raw material after drawing is cooled by the cooling fan 22 . When the cooling fan 22 is working, it generates wind force, which can take away the heat on the surface of the plastic raw material, thereby achieving cooling.

[0034] Among them, one end of the delivery pipe 15 is connected to the water supply pipeline 13, and the other end of the delivery pipe 15 is connected to the water pump 5. When the water pump 5 is working, it draws cooling water from the cooling water tank 3, transports the cooling water through the delivery pipe 15, and transports the cooling water to the water supply pipeline 13.

[0035] The plurality of air-cooling racks 2 are evenly spaced along the straight direction of the rack body 11 , and the plurality of air-cooling racks 2 can realize multiple air cooling of the plastic raw material, thereby improving the cooling and shaping quality and efficiency.

[0036] Working principle: When in use, Figure 3As shown, the plastic raw materials after drawing are laid along the multiple groups of cooling rollers 12 of the water-cooled frame 1. During the movement of the plastic raw materials after drawing, the cooling rollers 12 are driven to rotate by the friction force. The water pump 5 works to extract the cooling water inside the cooling water tank 3, and transports the cooling water through the delivery pipe 15. The cooling water is transported to the water delivery pipe 13, and then diverted to the cooling cavity 121 of each cooling roller 12 through the water delivery pipe 13. When the cooling water flows inside the cooling cavity 121, heat exchange is achieved, and the outer wall of the cooling roller 12 is cooled. The plastic raw material after drawing is in close contact with the outer wall of the cooling roller 12 for heat exchange. The plastic raw material after drawing is cooled and shaped through the outer wall of the cooling roller 12. The cooling water after heat exchange is concentrated into the return pipe 14, and then enters the drain pipe 16 through the return pipe 14, and then flows into the return water tank 4 through the drain pipe 16. The return water tank 4 collects the reflux cooling water. At the same time, the cooling fan 22 of the air-cooling rack 2 generates wind to take away the heat from the surface of the plastic raw material to achieve air cooling.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
