Description

Technical Field

[0001] The utility model relates to the field of drying and shaping devices, in particular to drying equipment for producing automobile wiring harness adhesive tapes. Background Art

[0002] As we all know, automotive wiring harness tape is mainly used to replace the original PVC tape. It has the functions of environmental protection, shock absorption, wear resistance, etc. It is specially used for automotive industrial wiring harness winding. It has strong surface anti-fouling ability and high temperature stability. The main highlight of automotive wiring harness tape base fabric lies in the environmental protection of the production process and the environmental protection of the product. The color weaving process is adopted in the production process, which reduces the dyeing process and avoids the impact of dyeing on environmental pollution. After the tape base fabric is adopted, the odor pollution caused by the later use of PVC tape is reduced. In recent years, due to the continuous improvement of environmental protection requirements of automobile manufacturers, the use of polyester and nylon base fabrics has been continuously increased. During the processing of polyester base fabric, a drying device will be used to dry and shape the water vapor on the surface of the fabric to obtain a dry and formed fabric, and then the fabric will be rolled up using a winding device to complete the drying of the fabric;

[0003] It has been found in the use of existing drying and shaping devices that the drying and shaping devices on the market generally use fans and heating wires to perform hot air drying on the polyester base cloth. During air drying, traditional air drying equipment generally dries the rubber pad while conveying it, but the air drying process requires a certain amount of time. If the air drying time is short, it is easy to cause incomplete air drying of the tape and residual moisture. Utility Model Content
