Description

Technical Field

[0001] This application relates to the field of cooling device technology, such as a rapid cooling device for manufacturing plastic tableware. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] In the production of plastic tableware, injection molding is a crucial step. After this step, the tableware is usually at a high temperature, and directly proceeding with subsequent processing can lead to a decline in product performance, such as increased internal stress and deformation. Therefore, effective cooling is essential to ensure product quality. While natural cooling is simple and easy to implement, its long cooling cycle significantly slows down overall production efficiency, which does not align with the high-efficiency production requirements of modern manufacturing.

[0004] Given this, air cooling technology is widely adopted due to its high flexibility, relatively low cost, and ability to effectively accelerate the cooling process. However, existing air cooling technologies have significant shortcomings in the cooling of plastic tableware. Specifically, a common practice is to install a fan directly above the conveyor belt and blow air onto the freshly formed tableware. While the initial intention of this design was to directly remove heat from the surface of the tableware, in practice, it encounters problems due to improper airflow design. Because baffles are usually installed on both sides of the conveyor belt to prevent tableware from falling or shifting, these baffles physically restrict the natural flow path of the airflow. After the air is blown out by the fan, most of the heat is not effectively transferred to the surrounding environment but is confined within the area enclosed by the fan and baffles, and is then drawn back in by the fan, forming an inefficient and heat-depriving cycle. This poor airflow cycle not only leads to low cooling efficiency but also causes hot air to accumulate in the area near the fan, further reducing the cooling effect. Summary of the Invention

[0005] This application provides a rapid cooling device for manufacturing plastic tableware. By setting an air outlet on the baffle, it overcomes the problem of airflow being restricted by the baffle in traditional air-cooling technology. The air blown by the fan can pass through the air outlet more smoothly, effectively carrying away heat and releasing it into the surrounding environment, avoiding the accumulation of hot air near the fan, thereby significantly improving cooling efficiency.
