Technical Field

[0001] This utility model belongs to the technical field of plastic granulators, specifically a plastic cooling structure for a plastic granulator. Background Technology

[0002] Plastics must undergo cooling treatment after production, which is determined by the material properties, production process requirements, and the performance requirements of the final product.

[0003] In current technology, the plastic cooling structure of a plastic granulator cools the plastic through physical means, causing the temperature of the plastic to drop and remain stable after production.

[0004] In the existing technology, traditional plastic pellets fall from top to bottom during the cooling process. The falling time is too fast, resulting in a short cooling time for the plastic and therefore the cooling effect is not obvious. Therefore, a plastic cooling structure for a plastic pelletizer is proposed to address the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-4 This utility model provides a plastic cooling structure for a plastic granulator, including a housing 1; a base 11 is fixedly connected to the inner side wall of the bottom of the housing 1; a spiral tube 12 is fixedly connected to the top of the base 11; a receiving platform 13 is fixedly connected to the end of the spiral tube 12; a connection port 14 is opened at the bottom of the receiving platform 13; the top of the connection port 14 is fixedly connected to the inner side wall of the top of the housing 1; a feed inlet 15 is opened at the top of the housing 1; and a discharge port 16 is opened at the bottom of the housing 1. During operation, the base 11 is fixedly connected to the inner side wall of the bottom of the housing 1, the spiral tube 12 is fixedly connected to the top of the base 11, and the receiving platform 13 is fixedly connected to the end of the spiral tube 12. The connection port 14 is opened at the bottom of the receiving platform 13, and the feed inlet 15 is opened at the top of the housing 1. The discharge port 16 is opened at the bottom of the housing 1. The discharge port 16 is provided so that plastic granules can enter from the feed port 15 and fall into the receiving platform 13. They then fall through the connection port 14 inside the receiving platform 13 into the spiral tube 12, and finally fall through the spiral tube 12 to the discharge port 16. After the plastic granules are produced, they need to be cooled to shape the plastic. In traditional methods, the plastic granules fall from top to bottom during the cooling process, which results in a short cooling time and an ineffective cooling effect. By setting the spiral tube 12 where the plastic falls, the plastic can stay inside the spiral tube 12 for a longer time, which prolongs the time it takes for the plastic to fall to the bottom and thus extends the cooling time, resulting in a better cooling effect.

[0027] Furthermore, such as Figure 4As shown, a rotating shaft 2 is fixedly connected to the bottom of the receiving platform 13; multiple push rods 21 are fixedly connected to the side wall of the rotating shaft 2; the multiple push rods 21 can rotate around the rotating shaft 2; during operation, the rotating shaft 2 is fixedly connected to the bottom of the receiving platform 13, and multiple push rods 21 are fixedly connected to the side wall of the rotating shaft 2, and the multiple push rods 21 can rotate around the rotating shaft 2. When plastic falls into the receiving platform 13, the plastic can be pushed by rotating the push rods 21, so that the plastic falls from the connection port 14. The rotation of the push rods 21 can prevent the plastic from accumulating inside the receiving platform 13.

[0028] Furthermore, such as Figure 2 As shown, a fan 3 is fixedly connected to the side wall of the housing 1; an air duct 31 is fixedly connected to the side wall of the fan 3; the air duct 31 is installed inside the receiving platform 13; the opening of the air duct 31 faces the connection port 14; during operation, the fan 3 is fixedly connected to the side wall of the housing 1, and the air duct 31 is fixedly connected to the side wall of the fan 3. The air duct 31 is installed inside the receiving platform 13, and the opening of the air duct 31 faces the connection port 14. When plastic falls from the connection port 14, if the amount of plastic is large, it will block the connection port 14. The air duct 31 can blow air into the connection port 14. When the connection port 14 is blocked, the blown air can disperse the plastic at the connection port 14, so that the connection port 14 can be discharged smoothly.

[0029] Furthermore, such as Figure 4 and Figure 5 As shown, a water tank 4 is fixedly connected to the top of the base 11; a water storage tank 41 is provided on the inner side wall of the water tank 4; a spiral tube 12 is inside the water storage tank 41; during operation, the water tank 4 is fixedly connected to the top of the base 11, and a water storage tank 41 is provided on the inner side wall of the water tank 4. The water storage tank 41 is filled with water, and the spiral tube 12 is cooled by water. Through heat conduction, the interior of the spiral tube 12 can be cooled, thereby reducing the temperature of the plastic. Through heat conduction, the plastic can be cooled and its plasticity can be stabilized, preventing the plastic from undergoing rapid cooling and causing thermal expansion and contraction.

[0030] Furthermore, such as Figure 2 As shown, a sealing ring 5 is fixedly connected to the top of the water tank 4; the sealing ring 5 is connected to the top of the water tank 4 and the bottom of the receiving platform 13, and is used to seal the bottom of the receiving platform 13 and the top of the water tank 4; during operation, the sealing ring 5 is fixedly connected to the top of the water tank 4, and the top of the water tank 4 and the bottom of the receiving platform 13 are sealed by the sealing ring 5 to prevent water from leaking out through the bottom of the receiving platform 13.

[0031] Furthermore, such as Figure 2As shown, multiple refrigeration units 6 are fixedly connected to the side wall of the housing 1; the multiple refrigeration units 6 are symmetrically arranged; a circulation channel 61 is fixedly connected to the side wall of the refrigeration unit 6; multiple nozzles 62 are installed on the side wall of the circulation channel 61; the openings of the multiple nozzles 62 are arranged facing the side wall of the water tank 4; during operation, multiple refrigeration units 6 are fixedly connected to the side wall of the housing 1, and the circulation channel 61 is fixedly connected to the side wall of the refrigeration unit 6. Multiple nozzles 62 are installed on the side wall of the circulation channel 61, and the openings of the nozzles 62 are aligned with the side wall of the water tank 4. The refrigeration units 6 can generate cold air, and the nozzles 62 can blow the cold air towards the side wall of the water tank 4. When the water tank 4 is cooling the plastic, the temperature inside the water tank 4 will rise due to heat conduction. By blowing cold air towards the side wall of the water tank 4 through the nozzles 62, the temperature of the water tank 4 can be reduced, and the plastic can continue to be cooled, thus realizing the recycling of the water tank 4.

[0032] Working Principle: During operation, a base 11 is fixedly connected to the inner bottom wall of the housing 1, a spiral tube 12 is fixedly connected to the top of the base 11, and a receiving platform 13 is fixedly connected to the end of the spiral tube 12. A connection port 14 is opened at the bottom of the receiving platform 13, an inlet 15 is opened at the top of the housing 1, and an outlet 16 is opened at the bottom of the housing 1. Plastic granules can enter through the inlet 15 and fall into the receiving platform 13, then through the connection port 14 into the spiral tube 12, and finally through the spiral tube 12 to the outlet 16. After production, the plastic granules need to be cooled to shape the plastic. During cooling, traditional plastic granules fall from top to bottom, resulting in excessively rapid falling. The cooling time of the plastic is relatively short, resulting in insufficient cooling effect. By installing a spiral tube 12 at the point where the plastic falls, the plastic can remain inside the spiral tube 12 for a longer time, extending the time it takes to fall to the bottom and thus improving the cooling effect. During operation, a rotating shaft 2 is fixedly connected to the bottom of the receiving platform 13, and multiple push rods 21 are fixedly connected to the side wall of the rotating shaft 2. These push rods 21 can rotate around the rotating shaft 2. When the plastic falls into the receiving platform 13, rotating the push rods 21 pushes the plastic, causing it to fall from the connection port 14. The rotation of the push rods 21 also prevents the plastic from accumulating on the receiving platform. The material is stacked inside the receiving platform 13. During operation, a fan 3 is fixedly connected to the side wall of the housing 1, and an air duct 31 is fixedly connected to the side wall of the fan 3. The air duct 31 is installed inside the receiving platform 13, and the opening of the air duct 31 is set towards the connection port 14. When plastic falls from the connection port 14, if the amount of plastic is large, it will block the connection port 14. Air can be blown through the air duct 31 to the connection port 14. When the connection port 14 is blocked, the plastic at the connection port 14 can be dispersed by the blown air, so that the connection port 14 can be smoothly discharged. During operation, a water tank 4 is fixedly connected to the top of the base 11. A water storage tank 41 is opened on the inner side wall of the water tank 4. The water storage tank 41 is filled with water, and the spiral tube 12 is cooled by water through heat transfer. The cooling system allows for internal cooling of the spiral tube 12, thereby reducing the temperature of the plastic. Through heat conduction, the plastic's cooling properties become more stable, preventing rapid cooling and thermal expansion / contraction. During operation, a sealing ring 5 is fixedly connected to the top of the water tank 4, sealing the top of the water tank 4 and the bottom of the receiving platform 13 to prevent water leakage. Multiple circulation channels 61 are fixedly connected to the side wall of the housing 1 and the side wall of the refrigeration unit 6. Multiple nozzles 62 are installed on the side wall of the circulation channel 61, with their openings aligned with the side wall of the water tank 4. The refrigeration unit 6 generates cold air, which is then blown towards the side wall of the water tank 4 by the nozzles 62.When water tank 4 cools the plastic, the internal temperature of water tank 4 rises due to heat conduction. Cool air is blown onto the side wall of water tank 4 through nozzle 62, which lowers the temperature of water tank 4, allowing for continued cooling of the plastic and enabling the water tank 4 to be reused.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
