Description

Technical Field

[0002] The heating plate is a component that converts electrical energy into thermal energy. It is composed of special thermal conductive materials and a heating wire group. When current passes through the heating wire group, the electrical energy is converted into thermal energy, causing the surface of the thermal conductive material to generate high temperature, thereby achieving the heating function.

[0003] The structure of the heating plate has an integrated structure. For example, CN 217018957U discloses a suspended fixed tight brazing heating plate, which includes: an integrally cast plate body, a heating coil wire is embedded in the plate body, and the heating coil wire is provided with a plurality of hanging wires for connecting with the supporting part of the casting processing equipment, and the plurality of hanging wires are evenly arranged along the winding direction of the heating coil wire; a connecting sleeve is provided in the middle of the plate body, and the heating coil wire passes through the heating sleeve. Before casting the plate body, the heating coil wire is suspended in the casting mold through the hanging wire, and then the casting slurry is poured into the casting mold to form the plate body. The casting slurry completely wraps the heating coil wire in the casting mold, so that the plate body can form a stable and tight combination with the heating coil wire after cooling and forming, and finally the sleeve is assembled on the plate body.

[0004] The heating plate also has a structure formed by welding a plate body and a sleeve. For example, CN 117862656A discloses a welding method for an aluminum heating plate, which comprises: assembling the sleeve and the plate body, and then performing electron beam welding on the connection between the sleeve and the plate body at least three times; during the at least three electron beam weldings, applying pressure to the axial direction of the sleeve; CN 216700363U discloses a high-efficiency integrated brazing heating plate, comprising: a heat-conducting plate body, a heat-dissipating plate body arranged below the heat-conducting plate body, and a heating wire arranged in a plate shape between the heat-conducting plate body and the heat-dissipating plate body, the lower surface of the heat-conducting plate body is provided with a receiving groove adapted to the heat-dissipating plate body, the heat-dissipating plate body is cast in the receiving groove, the receiving groove is provided with a mounting groove adapted to the heating wire, the mounting groove is provided with a plurality of coupling grooves with a diameter larger than the mounting groove, the heat-dissipating plate body is formed with a coupling ring embedded in the coupling groove and covering the heating wire, and a wire passing hole is provided in the middle of the heat-dissipating plate body for the heat-dissipating plate body to pass through.

[0005] However, the heating disk commonly used in the above-mentioned prior art has a seal on the sleeve surface, and liquid material is used for cooling during the machining process. If the liquid material enters the inside of the disk, it will have a significant adverse effect on the heating disk. Therefore, it is necessary to seal the seal of the heating disk.

[0006] In the prior art, tape is usually used for sealing, but the time cost of tape wrapping and tape removal is high, and it cannot completely ensure that liquid substances do not enter the interior of the heating plate.

[0007] Therefore, in view of the shortcomings of the prior art, there is an urgent need to provide a sealing tool that can tightly seal the opening of the heating plate and has low production cost and simple sealing. Utility Model Content
