Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices for polyurethane product production, and more specifically, it relates to a cooling device for polyurethane product production. Background Technique

[0002] In the existing technology, during the implementation of the cooling process for polyurethane product production, the cooling device usually relies on water cooling technology. This technology uses circulating water to take away heat from the heat source (i.e., the newly formed polyurethane product), thereby achieving the purpose of cooling. However, there are certain limitations in the connection of the existing cooling devices, which directly affect the cooling effect and the use efficiency of the equipment.

[0003] Specifically, the existing cooling devices may lack convenient interfaces or adapters when connecting pipes, valves, and other components. This results in a cumbersome and time-consuming connection process and may require special tools or skills. In addition, the instability of the connection may cause cooling water leakage, which not only wastes resources but also may pollute the production environment. At the same time, the connection problems may also affect the flow rate and pressure of the cooling water, thereby affecting the cooling effect. These problems not only reduce production efficiency but also may affect the quality and performance of the final product. Content of the Utility Model

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a cooling device for the production of polyurethane products, which has the following beneficial effects:

[0017] 1. The connecting mechanism realizes the effective connection between the cooling device and the external equipment through the setting of the fixed sleeve, the external pipe, the sealing sleeve, the intermediate rod and the intermediate sleeve. The intermediate rod and the intermediate sleeve installed in the fixed sleeve, and the connection between the external pipe and the sealing sleeve provide a flow channel for the cooling water. The pressing of the sealing sleeve and the sealing groove, and the cooperation of the one-way plate and the one-way block ensure the sealing and stability of the connection. This design enables the cooling device to be easily connected to the external equipment, improving the convenience of use and the cooling effect.

[0018] 2. The clamping mechanism realizes the fixation and sealing of the outer connecting pipe through the staggered installation of the one-way plate and the one-way block, and the cooperation of the spring and the tension spring. The one-way plate is clamped on the one-way block, and a fixed force is applied through the spring. The tension spring enables the sealing sleeve and the sealing groove to be sealed. This design enables the outer connecting pipe to be firmly fixed in the fixed sleeve during the fixation process, while ensuring the sealing performance of the connection, improving the use effect and reliability of the fixing mechanism.

[0019] 3. The limiting mechanism realizes the limiting fixation of the outer connecting pipe through the setting of the hexagonal sleeve and the abutting sleeve, and the cooperation of the push plate and the lateral groove. The hexagonal sleeve is threadedly connected to the fixed sleeve. By changing the position of the hexagonal sleeve, the position of the push plate can be changed, thereby reducing the elastic force of the spring and enabling the one-way plate to be in the gap between the one-way blocks, facilitating the extraction of the outer connecting pipe. This design enables the outer connecting pipe to remain stable during the fixation process, avoiding the instability or failure of fixation caused by position changes, and improving the use effect and stability of the limiting mechanism.
