Description

Technical Field

[0001] The utility model belongs to the technical field of automobile production, in particular to a cooling device for a heat sealing machine. Background Art

[0002] Car seats are one of the important components of cars. Car seats are generally composed of an internal wire frame and an external leather cover. In the production process of leather covers for car seats, heat sealers are often used. The use of heat sealers can not only achieve the splicing between leather materials, but also achieve the printing of leather products, etc. In the use of heat sealers, the cooling device is one of the important components of the heat sealer. The cooling device can quickly cool the leather products after the heat sealer processing, which is convenient for the next process. The cooling device is usually composed of a fan and a workbench. The fan provides fresh air to the inside of the workbench, and the fresh air is evenly provided to the leather products through the air outlet on the workbench surface, thereby achieving rapid cooling of the leather products.

[0003] However, it still has the following disadvantages in actual use:

[0004] In the cooling device described above, the fresh air inside the workbench is delivered to the leather product through the air outlet, thereby accelerating the cooling speed of the leather product. However, the air outlet has no dust-proof structure, so that when it is not needed, dust can easily enter the workbench through the air outlet. When it is used next time, the dust inside the workbench adheres to the leather product along with the fresh air, causing stains on the surface of the leather product.

[0005] The cooling device described above uses the fresh air generated by the fan to quickly cool the leather product. However, due to the small temperature difference between the fresh air and the leather product, the heat dissipation speed of the leather product is slow, resulting in low cooling efficiency of the leather product.
