Description

Technical Field

[0001] This utility model relates to the field of TPU production, specifically a TPU material cooling device. Background Technology

[0002] TPU (thermoplastic polyurethane) is a high-performance elastomer material that combines the elasticity of rubber with the processing convenience of plastics. It is generally prepared by the polymerization reaction of polyols, isocyanates, and chain extenders (such as butanediol).

[0003] In current technology, when TPU materials are prepared, they are extruded through an extruder and then cooled inside a cooling device. There are two types of cooling devices: water cooling and air cooling. Water cooling can quickly cool and inhibit crystallization, making the masterbatch softer and more transparent. However, it is necessary to strictly dry the masterbatch to prevent moisture residue. Air cooling can slowly cool (such as air cooling) and increase crystallinity, making the material harder.

[0004] However, in use, the existing air-cooled cooling devices have poor airflow uniformity, resulting in poor cooling uniformity and affecting the cooling effect; therefore, a TPU material cooling device is proposed to address the above problems. Utility Model Content

[0013] 1. This utility model, by setting up a box, sleeve, bracket and inner cylinder, when in use, the air outlet of the fan delivers airflow into the inside of the sleeve through the air supply pipe. The airflow enters the cavity and then sprays out through the through hole on the inner cylinder in the middle of the sleeve.

[0022] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1-4 As shown, a TPU material cooling device includes a fan 11, with an air supply pipe 12 fixedly connected to the air outlet end of the fan 11; it also includes a housing 13, with a support 14 fixedly connected to the inner wall of the housing 13, and a sleeve 15 fixedly connected to the support 14. The sleeve 15 has a cavity inside, the air supply pipe 12 is fixedly connected to the sleeve 15, and the air supply pipe 12 communicates with the cavity. An inner cylinder 16 is fixedly connected to the middle of the sleeve 15, and the inner cylinder 16 has multiple through holes 17. A through groove 18 is formed on the housing 13 at a position corresponding to the sleeve 15.

[0025] During use, the air outlet of the fan 11 delivers airflow into the sleeve 15 through the air supply pipe 12. The airflow enters the cavity and is then ejected through the through hole 17 on the inner cylinder 16 in the middle of the sleeve 15. The TPU material enters through the through groove 18 of the box 13 and then passes through the middle of the inner cylinder 16. The airflow ejected from the through hole 17 forms a ring to cool the TPU material, so that the airflow surrounds the TPU material, thereby improving the uniformity of cooling and ensuring the cooling effect.

[0026] Furthermore, such as Figure 1-4As shown, it also includes a filter element 22, on which an air inlet pipe 21 is installed. The end of the air inlet pipe 21 is fixedly connected to the air inlet end of the fan 11. An air guide cover 31 is fixedly connected to the side of the fan 11, and a connecting pipe 32 is fixedly connected to the side of the air guide cover 31. The filter element 22 includes a housing 33 and a filter element 34. The middle part of the housing 33 is fixedly connected to the end of the connecting pipe 32, and the end of the air inlet pipe 21 is fixedly connected to the top of the housing 33. The filter element 34 is installed inside the housing 33, and the end of the connecting pipe 32 is located at the bottom of the filter element 34. An opening 42 is provided at the bottom of the housing 33, and an end cap 41 is threadedly connected to the opening 42. The filter element 34 is threadedly connected to the inner wall of the housing 33.

[0027] During use, the air inlet of the fan 11 is connected to a filter element 22 via an air inlet pipe 21. The filter element 22 filters the adsorbed air, thereby reducing dust adhesion to the surface of the TPU material before it has cooled down, reducing the impact on the product, and reducing the clogging of the through hole 17. The filter element 22 consists of a housing 33 and a filter element 34. The internal filter element 34 is used to filter the air. An air guide cover 31 is installed on the side of the housing 13. The air inlet on the housing 33 is connected to the air guide cover 31 via a connecting pipe 32 to draw in the filtered air sprayed from inside the housing 13. This reduces the frequency of filter element 34 replacement. The filter element 34 is fixed inside the housing 33 by threads, making it easy to replace and clean the filter element 34.

[0028] Furthermore, such as Figure 3 As shown, the through hole 17 is inclined away from the through groove 18, and a flow guide seat 5 is fixed to one end of the sleeve 15 near the through groove 18. The middle part of the flow guide seat 5 has a conical structure.

[0029] In use, the through hole 17 is inclined away from the through groove 18, which can reduce the flow of air towards the through groove 18, thereby reducing the ejection of air and facilitating its subsequent absorption and circulation. The guide seat 5 is provided to block the airflow from being ejected towards the through groove 18.

[0030] Furthermore, such as Figure 2-3 As shown, multiple through holes 17 are evenly distributed on the inner cylinder 16, three sleeves 15 are provided, the air guide cover 31 is arranged in a conical structure, and the three sleeves 15 are arranged in a linear array.

[0031] Furthermore, such as Figure 5 As shown, a heat exchanger 7 is installed inside the housing 13. During use, the heat exchanger 7 can exchange heat with the hot air in the housing 13 after long-term operation, reduce the air temperature, and facilitate subsequent heat recovery.

[0032] Working principle: During use, the air outlet of the fan 11 delivers airflow into the sleeve 15 through the air supply pipe 12. The airflow enters the cavity and is then ejected through the through-hole 17 on the inner cylinder 16 in the middle of the sleeve 15. The TPU material enters through the through-slot 18 of the housing 13 and passes through the middle of the inner cylinder 16. The airflow ejected from the through-hole 17 forms a ring to cool the TPU material, ensuring that the airflow surrounds the TPU material, thereby improving the uniformity of cooling and ensuring the cooling effect. The air inlet of the fan 11 is connected to a filter element 22 through the air inlet pipe 21. The filter element 22 filters the adsorbed air, thereby reducing dust adhesion to the surface of the uncooled TPU material, reducing the impact on the product, and reducing the clogging of the through-hole 17. The filter element 22 consists of a housing 33 and a filter element 34. It filters air by relying on the internal filter element 34. An air guide cover 31 is installed on the side of the housing 13. The air inlet on the housing 33 is connected to the air guide cover 31 through a connecting pipe 32 to draw in the filtered air sprayed from inside the housing 13. This reduces the frequency of filter element 34 replacement. The filter element 34 is fixed inside the housing 33 by threads, so it is easy to replace and clean the filter element 34. In use, the through hole 17 is inclined away from the through groove 18, so as to reduce the airflow towards the through groove 18, thereby reducing the airflow ejection and facilitating its subsequent absorption and circulation. A guide seat 5 is provided to block the airflow from being ejected towards the through groove 18.
