[0002] Also known as plastic molding, it is a general term for various processes that convert synthetic resins or plastics into plastic products. It is a large production department in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic has been molded into finished products or semi-finished products, also known as plastic secondary processing. In the process of plastic processing, extruders are generally used. In plastic extrusion molding equipment, plastic extruders are usually called main machines, and the subsequent equipment plastic extrusion molding machines that match them are called auxiliary machines. After more than 100 years of development, plastic extruders have evolved from the original single screw There are many types of machines, such as twin-screw, multi-screw and even screw-free. Plastic extruder can be matched with various plastic molding auxiliary machines such as pipes, films, holding materials, monofilaments, flat wires, strapping tapes, extruded nets, plates, sheets, materials, profiles, granulation, cable coating, etc. to form various plastic extrusion molding production lines and produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used machines in the plastic processing industry now and in the future.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] The utility model provides Figure 1-4A cooling device for a plastic extruder shown in the figure includes a cooling pool 1, a water tank 15 is arranged on one side of the cooling pool 1, a first water pump 16 is installed on the upper end of the water tank 15, a second water pump 17 is arranged on one side of the outer wall of the water tank 15, the other end of the second water pump 17 is connected to a return pipe 18, and a fixing ring 19 is installed inside the return pipe 18.
[0025] like Figure 1-3 As shown, the inner wall of the cooling pool 1 is connected with a connecting rod 2, the outer wall of the connecting rod 2 is movably connected with a rotating shaft 3, one side of the rotating shaft 3 is connected with a buffer plate 4, and the lower end of the connecting rod 2 is provided with a telescopic support rod 5. The setting of the buffer plate 4 can play a buffering role in the process of the falling of the finished plastic product.
[0026] like Figure 1-3 As shown, a screw rod 6 is provided inside the cooling pool 1, and a driving motor 7 is connected to the upper end of the screw rod 6. A sliding rod 8 is provided on one side of the screw rod 6. A movable ring 9 is movably connected to the outer wall of the screw rod 6. A screw rod 10 passes through the upper end of the movable ring 9, and one end of the screw rod 10 is connected to a collecting net 11. The screw rod 10 connected to the collecting net 11 can connect the collecting net 11 with the movable ring 9, which is convenient for replacing the collecting nets 11 with different hole diameters for use when facing plastic particles of different sizes, so that the cooling device is more flexible to use.
[0027] like Figure 1-3 As shown, a bracket 12 is provided at the upper end of the cooling pool 1, a grille 13 is connected to the upper end of the bracket 12, and a fan 14 is installed at the lower end of the grille 13. The fan 14 can be set to air-cool the finished plastic product before it enters the cooling pool 1, thereby improving the hardness of the plastic product and preventing the deformation of the plastic product when the cooling pool 1 cools the finished plastic product.
[0028] like Figure 1-4 As shown, a slide groove 20 is provided on the inner wall surface of the fixing ring 19, and a damping reset rod 21 is provided on the inner wall of the slide groove 20, and a stop block 22 is installed at the other end of the damping reset rod 21. A filter screen 23 is movably connected to the inner wall of the fixing ring 19, and the filter screen 23 is movably connected to the slide groove 20. The hole diameter of the filter screen 23 is "0.04mm". The setting of the filter screen 23 can filter the water recovered from the cooling pool 1 to reduce the plastic debris remaining in the water. A slider 24 is installed on the outer wall of the filter screen 23. The cooperation of the stop block 22 and the damping reset rod 21 can limit the lower end of the slide groove 20 after the filter screen 23 is connected to the slide groove 20 through the slider 24, so as to prevent the filter screen 23 from falling off under the impact of the water flow. Secondly, when the filter screen 23 needs to be disassembled and cleaned, it only needs to be pulled down. During the pulling down process, the outer wall of the stop block 22 is arc-shaped, so that the filter screen 23 can be taken out in cooperation with the contraction of the damping reset rod 21.
[0029] The working principle of the utility model is as follows: first, the cooling pool 1 is moved to one side of the extruder, and then the external power supply of the cooling pool 1 is turned on, and then the switch of the first water pump 16 is turned on, so that the first water pump 16 pumps the water in the water tank 15 into the cooling pool 1, and then the buffer plate 4 is adjusted in angle through the telescopic support rod 5. After the angle of the buffer plate 4 is adjusted, the switch of the fan 14 is turned on, so that the fan 14 air-cools the finished plastic product entering the cooling pool 1, and the finished plastic product can be cooled and hardened during the air-cooling process. Then, after the plastic product enters the cooling pool 1 along the buffer plate 4, the switch of the second water pump 17 is turned on. When the cooling pool 1 is in use, the second water pump 17 pumps the water in the cooling pool 1 back into the water tank 15. The recovered water is quickly cooled by the refrigeration device arranged inside the water tank 15. The recovered water is then pumped into the cooling pool 1 by the first water pump 16 for use, thereby playing a role of water cooling circulation, so that the water temperature inside the cooling pool 1 will not be too high. After the finished plastic product is cooled, the buffer plate 4 is dropped, and the switch of the driving motor 7 is turned on, so that the driving motor 7 drives the collecting net 11 to salvage the finished plastic product. Finally, the external power supply of the device can be cut off when the device is not in use.
[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
