[0002] High temperature resistant tape is an adhesive tape used in high temperature working environment. It is mainly used in the electronics industry. Its temperature resistance is usually between 120 and 260 degrees. It is often used in spray painting, baking varnish leather processing, coating masking, fixing in electronic parts manufacturing process, printed circuit boards and high temperature processing masking.

[0003] In the general production process of high temperature resistant tape, it is necessary to coat the tape substrate so that a glue layer is formed on the adhesive surface of the tape. The existing technology for coating process generally adopts coating machine processing.

[0004] As shown in Chinese patent CN202020106258.0, the traditional coating machine is generally composed of a winding drum, a feeding drum, a gluing die head (coating roller), etc. The substrate is unwound by the feeding drum and coated with glue by the gluing die head, dried by the drying system, and finally wound by the winding drum. This type of coating machine equipment is generally arranged in an assembly line, occupies a large area, and does not have the function of glue recovery, resulting in limitations in use. Therefore, the utility model proposes a high-temperature resistant tape coating machine, which integrates the unwinding roller, tape guide roller A, tape guide roller B, coating assembly, drying assembly and winding roller on a frame, has good integration and occupies a small area. In addition, the utility model is configured with a glue vapor recovery pipe. The glue vapor recovery pipe can, on the one hand, recover the glue liquid to the tape outlet cavity, and collect it by condensation by the condensation row, and flow through the inner wall of the tape outlet cavity to the central cavity for collection. In addition, the glue vapor recovery pipe can send the glue vapor to the tape inlet cavity. The glue vapor will adhere to the surface of the substrate in the tape inlet cavity, making the subsequent coating of the coating roller smoother. Utility Model Content
