Description

Technical Field

[0001] The utility model relates to the technical field of infrared drying, in particular to an infrared drying device for rigid polyurethane foam composite boards. Background Technique

[0002] The infrared drying device for rigid polyurethane foam composite boards is a device specifically used for drying rigid polyurethane (PU) foam and its composite materials. This device uses infrared radiation as the main heat source, and the far-infrared rays generated by the infrared heating element irradiate the rigid polyurethane foam composite board, so that the moisture inside the board evaporates rapidly, thereby realizing drying. Infrared drying has the advantages of high heating efficiency, low energy consumption, fast drying speed, etc., and is suitable for application in large-scale industrial production.

[0003] An infrared drying device for rigid polyurethane foam composite boards with the publication number of CN210463809U includes a box body and an infrared dryer installed on the top surface inside the box body. A lower shell is arranged below the box body, and the lower shell and the box body are of an integral structure. A cylinder is fixedly connected above the lower shell through bolts, and the output end of the cylinder penetrates and is fixed with a connecting plate. The cylinder can drive the fixing plate above the connecting plate to move up and down quickly, and then quickly pick up and place the composite board between the two clamping rods, thus solving the problem of inconvenient picking up and placing of the composite board in the original infrared drying device. Through the front radiation of the infrared dryer from top to bottom, combined with the reflection effect of the reflection film, it acts on the lower surface of the composite board in the drying device through the through holes, ensuring the normal progress of the full drying process of both sides of the composite board, and improving the drying efficiency of the composite board to a certain extent.

[0004] As shown in the above device, in the existing infrared drying device for rigid polyurethane foam composite boards, the rigid polyurethane foam composite board will move due to the expansion of the internal gas during the drying process. Without a clamping mechanism to fix the board, the position of the board in the drying chamber will be unstable, which will affect the uniform distribution of heat and lead to uneven drying.
