Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a bubble-proof prepreg tire body drying device. Background Art

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc. They are flexible building materials that can be rolled into a roll to prevent external rainwater and groundwater leakage. As a leak-free connection between the engineering foundation and the building, they are the first barrier to waterproofing the entire project and play a vital role in the entire project. The carcass needs to be dried during processing to complete the entire processing process.

[0003] At present, in the production process of waterproof membrane, the carcass needs to go through two treatment processes: pre-impregnation and coating. During the pre-impregnation process, bubbles will be generated on the carcass. After the pre-impregnation is completed, bubbles will remain on the carcass. Direct coating will affect the performance and appearance of the membrane.

[0004] For example, the prepreg carcass drying device disclosed in Chinese patent CN215809937U includes a heating mechanism, and the key is that the drying device also includes a frame frame arranged between the prepreg tank and the coating tank, and a driving mechanism fixed on the frame frame, and the heater includes a first heating roller and a second heating roller arranged on the frame frame and parallel to each other, the first heating roller is located between the prepreg tank and the second heating roller, and the first heating roller and the second heating roller both form a transmission match with the driving mechanism. The problem that bubbles are generated on the carcass during the prepreg process in the related art, bubbles remain on the carcass after the prepreg is completed, and direct coating treatment will affect the performance and appearance of the coil is solved.

[0005] However, the prepreg carcass drying device performs two drying operations on the carcass to remove bubbles on the carcass surface, which is not effective enough. Simply relying on two drying operations is not enough to remove bubbles thoroughly.

[0006] Therefore, we propose an anti-bubble prepreg carcass drying device to solve the above problems. Utility Model Content
