Description

Technical Field

[0001] The utility model relates to the technical field of steel-aluminum-plastic belt processing, in particular to a high-temperature resistant belt hollow covering device. Background Art

[0002] Steel-aluminum-plastic composite tape is a composite material formed by hot-coating an organic film on the surface of a precision cold-rolled steel-aluminum-plastic tape or aluminum tape. It is a key armor material in optical cables. In the production process of steel-aluminum-plastic composite tape, coating is a key process. The main process of the coating process section is steel (aluminum) coil unwinding - upper induction oven preheating - hot film lamination - lower induction oven heating - air cooling - winding.

[0003] Existing technologies, such as Chinese utility model patent No. 202221584151.2, propose a coating device for high-temperature resistant and anti-sticking steel aluminum-plastic tape, including a coating frame, an upper oven, a film roll, a pressing roller, a lower oven, and an air cooling system, a water cooling system and a product winding roll are arranged on the side of the lower oven outputting the product; wherein a coating roller is installed between the air cooling system and the lower oven; a coating roller is arranged at the outlet of the lower induction oven; an anti-stick coating is arranged on the outer peripheral wall of the coating roller; the coating roller is a hollow structure , and a working fluid inlet and a working fluid outlet are respectively provided at both ends, so as to realize the cooling treatment of the coated roller. However, the installation of the water-cooling structure and the roller in motion involves sealing connection, water inlet and drainage, etc., and it must be ensured that it is carried out in the motion state. Secondly, although the Teflon coating will not cause the roller to adhere to the outer surface of the steel-aluminum-plastic belt coating, the problem of static electricity is not considered. When static electricity is generated at the contact point, it will affect the steel-aluminum-plastic belt coating, resulting in problems such as the film surface being not so smooth. Therefore, an improved technology is proposed. Utility Model Content

[0004] The utility model solves the problems that the water cooling installation is complicated and static electricity cannot be avoided, and reduces the surface quality of the steel-aluminum-plastic belt.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a high temperature resistant belt hollow covering device, comprising a film coating roller assembly installed between the lower ovens; a Teflon coating is arranged on the outer peripheral wall of the film coating roller assembly, the film coating roller assembly comprises an upper box body and a lower box body located below the upper box body and at a distance, a side box body is arranged on one side of the upper box body and the lower box body, the side box body has openings at the upper and lower ends, and the sides opposite to the upper box body and the lower box body both begin to have receiving openings, the openings of the side box body are respectively connected with the receiving openings of the upper box body and the lower box body, and the upper box body, the side box body and the lower box body form a U-shaped structure with the opening facing the side;

[0006] A coating sponge 1 is installed in the upper box body, a coating sponge 2 is installed in the side box body, and a coating sponge 3 is installed in the upper end of the lower box body. The upper and lower ends of the coating sponge 2 are respectively abutted against the upper and lower ends of the adjacent coating sponge 1 and the coating sponge 3. A plurality of liquid absorbing cores are installed at the lower end of the coating sponge 3. The lower end of the liquid absorbing core is located on the bottom surface of the lower box body, and an antistatic liquid is provided in the lower box body.

Bearings are installed in the mounting holes. Rollers are fixed to the inner rings of the bearings. The outer surfaces of the rollers are coated with Teflon coatings. The rollers are in contact with the adjacent coating sponges 1 and 3 respectively. The rollers are hollow structures. Air inlet pipes and working medium output ends are respectively arranged at both ends. The rollers are cooled by exhausting gas, i.e., air cooling.

[0008] A liquid injection port is arranged near the upper end of one side of the lower box body, and a water cooling and heat dissipation system is arranged in the lower box body.

[0009] Furthermore, the air inlet duct is powered by a fan to deliver air to the air inlet duct, and the working medium output end is a plurality of air holes opened at the free end of the tube.

The water-cooling block is a metal block with water channels inside, made of copper or aluminum, located at the lower end of the lower box body, and absorbs heat from the lower box body and its internal medium.

[0013] The advantages of the utility model compared with the prior art are:

[0014] 1. Change the water cooling of the roller to air cooling. The connection is relatively simple. There is no need to consider the circulation of the working medium in the water cooling, as well as the installation problems such as the sealing connection in the sealed state. It only needs to connect the fan. The centrifugal force of the fan exhausts the gas through the roller and then discharges it from the other end, which also achieves the effect of cooling the roller.

[0015] 2. In order to avoid static electricity, the upper and lower ends of the roller and the coating sponge 1 and the coating sponge 3 are in contact with each other. The coating sponge 1 and the coating sponge 3 absorb each other's attached liquids and apply them on the outer surface of the roller, thereby avoiding static electricity;

[0016] 3. In order to further improve the cooling effect, the electrostatic liquid will be cooled by the water cooling equipment in the lower box, and the temperature of the electrostatic liquid applied to the outside of the roller is lower, which can cool the roller, while increasing the production speed, it can effectively increase the service life of the roller.
