Description

Technical Field

[0001] This utility model relates to the field of twin-screw extruder technology, specifically a twin-screw extruder with a rapid cooling mechanism. Background Technology

[0002] Twin-screw extruders are core equipment in material processing. Their barrels and screws require rapid cooling with circulating water to stabilize the process. Existing circulating water contains impurities, rust, and cooling debris, which can easily clog cooling channels and filters. Traditional filters require shutdown and disassembly for cleaning, lack online cleaning of filter plates and convenient dust collection structures, resulting in inefficient impurity removal. Long-term operation leads to reduced cooling efficiency and overheating of the equipment, affecting product quality. There is an urgent need for a convenient and efficient integrated device to solve the above problems.

[0003] A search revealed a Chinese patent publication number, CN216506671U, which discloses a twin-screw extruder. This patent, by setting up heat dissipation components and a coolant cooling structure, can efficiently dissipate heat and cool down the drive motor and conveyor cylinder, and can also cool down the coolant used for cooling, thereby improving the practicality of the extruder.

[0004] Although the aforementioned patent can dissipate heat and cool the cylinder, the above-mentioned coolant circulation process still has the following problems: after the coolant flows out of the cylinder, it first enters the second heat dissipation component, and then directly enters the interior to be pumped away by the water pump. It does not take into account the impurities contained in the circulating water. The impurities in the water flow can clog the pipes, which can easily cause the cooling of the device to malfunction. It also requires manual shutdown and cleaning of the machine after a period of use, which greatly reduces work efficiency. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0018] Please see Figure 1-5This utility model provides a technical solution: a twin-screw extruder with a rapid cooling mechanism, including a machine body 1. The machine body 1 has an existing structure and will not be explained in detail here (see patent: CN216506671U). A cooling device is installed inside the machine body 1 to cool down the heat. A feed pipe 2 is installed at the top of the machine body 1, through which materials can enter the machine body 1 for processing. A recovery box 14 is installed inside the machine body 1 to collect and circulate the cooling water. A filter plate 17 is fixedly connected inside the recovery box 14 to filter and block impurities in the water. A stabilizing plate 15 is fixedly connected inside the recovery box 14. A groove is formed at the bottom of the stabilizing plate 15, and a rotating part is rotatably connected inside the groove at the bottom of the stabilizing plate 15. A threaded rod 18 extends to the outside of the equipment body 1. A slider 22 is slidably connected inside the groove at the bottom of the stabilizing plate 15. The inside of the slider 22 is threadedly connected to the surface of the threaded rod 18. A telescopic support rod 23 is fixedly connected to the bottom of the slider 22. A telescopic rod 6 extending to the outside of the telescopic support rod 23 is slidably connected inside the telescopic support rod 23. A cleaning plate 19 is fixedly connected to the bottom of the telescopic rod 6. A brush is provided at the bottom of the cleaning plate 19. The cleaning plate 19 can clean the impurities on the top of the filter plate 17 through the brush, so that the filter plate 17 can block and filter the impurities in the water flow more smoothly and allow the water flow to circulate and cool more smoothly. At the same time, it reduces the blockage of impurities in the pipes in the water flow to a certain extent, which may cause the cooling of the device to fail. This allows the staff to use the device more smoothly. A power transmission device is provided on one side of the equipment body 1.

[0019] The main body of the equipment 1 is equipped with a movable door. A maintenance groove 16 communicating with the inside of the recycling bin 14 is opened on one side. A collection frame 20 is slidably connected inside the maintenance groove 16. The collection frame 20 is fixedly installed on the recycling bin 14 by bolts. The collection frame 20 can collect the cleaned impurities. The bottom of the collection frame 20 is provided with a mesh, which allows water to be discharged more smoothly.

[0020] A spring 21 is fixedly connected to the top of the telescopic rod 6. The top of the spring 21 is fixedly connected to the inner wall of the telescopic support rod 23. The spring 21 can be compressed and reset by moving the telescopic rod 6 up and down. The filter plate 17 is set in an inclined position inside the recycling box 14. The force of the spring 21 on the telescopic rod 6 makes the cleaning plate 19 always stick to the surface of the filter plate 17, making the cleaning of the filter plate 17 more convenient.

[0021] The power transmission device includes a protective frame 3. One side of the protective frame 3 is fixedly connected to the interior of the equipment body 1. A motor 4 is fixedly connected to one side of the protective frame 3. The motor 4 is an existing structure and will not be explained in detail here. The output end of the motor 4 rotates through one side of the protective frame 3 and extends into the interior of the protective frame 3. A transmission rod 5 is fixedly connected to the output end of the protective frame 3. One end of the transmission rod 5 rotates through the interior of the protective frame 3 and extends into the interior of the feed pipe 2. One end of the threaded rod 18 rotates through one side of the protective frame 3 and extends into the interior of the protective frame 3. A second sprocket 13 is fixedly connected to the surface of the threaded rod 18 inside the protective frame 3. A first sprocket 11 is fixedly connected to the surface of the transmission rod 5 inside the protective frame 3. A chain 12 is meshed with the surface of the first sprocket 11. The surface of the chain 12 meshes with the second sprocket 13. The first sprocket 11 and the second sprocket 13 rotate synchronously through the chain 12. A power frame 10 is fixedly connected inside the feed pipe 2. A stirring rack 9 extending to the outside of the power frame 10 is rotatably connected inside the power frame 10. A second bevel gear 8 is fixedly connected to the bottom of the stirring rack 9. A transmission rod 5 rotatably passes through one side of the power frame 10 and extends into the inside of the power frame 10. A first bevel gear 7 is fixedly connected to the surface of the transmission rod 5. The surface of the first bevel gear 7 meshes with the surface of the second bevel gear 8.

[0022] When the operator starts the motor 4, the motor 4 drives the transmission rod 5 to rotate. The transmission rod 5 is connected by the meshing of the first bevel gear 7 and the second bevel gear 8, which drives the mixing frame 9 to rotate. The mixing frame 9 can mix and crush the material entering the feed pipe 2, which reduces the occurrence of agglomeration of the material entering the feed pipe 2 and prevents blockage inside the feed pipe 2. This allows the material to be fed more smoothly.

[0023] Working principle: For this type of machine, the operator first starts the motor 4, which drives the transmission rod 5 to rotate. The transmission rod 5 is connected by the meshing of the first bevel gear 7 and the second bevel gear 8, which drives the mixing frame 9 to rotate. The mixing frame 9 can mix and crush the material entering the feed pipe 2, which reduces the occurrence of agglomeration of the material entering the feed pipe 2 and prevents blockage inside the feed pipe 2. This allows the material to be fed more smoothly and the equipment body 1 to process the material more smoothly. Simultaneously, the transmission rod 5 drives the first sprocket 11 to rotate. The first sprocket 11 and the second sprocket 13 rotate synchronously through the chain 12, thereby causing the second sprocket 13 to drive the stabilizing plate 15 to rotate. Through the forward and reverse rotation of the motor 4, the threaded rod 18 can drive the slider 22 to move back and forth, so that the cleaning plate 19 can clean the impurities on the top of the filter plate 17 through the brush. This allows the filter plate 17 to more effectively block and filter impurities in the water flow, and allows the water flow to circulate and cool more smoothly. At the same time, it reduces the blockage of impurities in the pipes in the water flow to a certain extent, thus reducing the cooling failure of the device and allowing the staff to use the device more smoothly.

[0024] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
