Description

Technical Field

[0001] This application relates to the technical field of foam production, and particularly relates to a foam drying oven. Background Art

[0002] Foam is a microporous plastic. Foam plastics are a type of polymer material formed by a large number of gas micropores dispersed in solid plastics. They have characteristics such as light weight, heat insulation, sound absorption, and shock absorption, and their dielectric properties are superior to those of the matrix resin. They have a wide range of uses. After the foam plastics are foamed and processed into a molded shape, due to the cooling process, the foam plastics are prone to shrinkage when cooled, resulting in deformation. Therefore, the cooled foam plastics need to be placed in a drying oven for baking. On the one hand, it can dry the cooling water on the surface, and on the other hand, it can make the shrunk foam plastics expand and return to their original state. After retrieval, the patent document with the authorization announcement number CN217979543U discloses a foam foaming drying oven, including a drying oven. A double-sided drying mechanism is provided inside the drying oven. The double-sided drying mechanism includes a first heating plate fixedly installed on the upper surface of the inner cavity of the drying oven. Second heating plates are fixedly installed between the lower surface of the inner cavity of the drying oven and the left and right surfaces of the inner cavity of the drying oven. Two support rods are fixedly installed on the upper surface of the second heating plate. A hollow plate is fixedly installed at one end of the support rod away from the upper surface of the second heating plate. Heating coils are fixedly installed on the lower surfaces of the inner cavities of the first heating plate and the second heating plate. In this foam foaming drying oven, by providing a first heating plate and a second heating plate inside the drying oven and a hollow plate on the second heating plate, the upper and lower surfaces of the foam plastics can be heated simultaneously, and the upper and lower surfaces of the foam plastics can be uniformly heated simultaneously, which is beneficial to improving the quality of the foam plastics.

[0003] The above-mentioned related solutions are found to still have at least the following deficiencies in actual use: When placing the foam plastics on the hollow plate in the internal space of the drying oven, it is necessary for the operator to reach into the drying oven, and when taking out the foam plastics, it is also necessary to reach into the internal space of the drying oven. The operation is not convenient enough and the practicability is poor. Moreover, during the baking process of the foam plastics, the hot air flow in the internal space of the drying oven is relatively poor, which will cause the temperature in the upper and lower spaces of the drying oven to be higher than that in the middle space, resulting in uneven heat distribution in the internal space of the drying oven and affecting the baking quality of the foam plastics.

[0004] Therefore, we propose a foam drying oven to solve the above problems. Utility Model Content
