[0002] Dental pads are an auxiliary tool used in dental treatment, usually placed on teeth or between gums, to absorb saliva, clean tooth surfaces, protect teeth and soft tissues, etc. In dental treatment, dental pads are widely used in occlusal surface repair, root canal treatment, teeth cleaning, tartar cleaning, tooth extraction and other operations. During the production process of dental pads, the surface needs to be coated, which requires the use of a heating roller.

[0003] The prior art with patent publication (announcement) number CN204451431U discloses a novel dental pad coating roller, which is a roller that is provided with an electric heating rod on the inner surface of the original coating roller to heat the roller, so that the plastic film has a temperature when passing through the roller; it comprises a roller and four electric heating rods, which are evenly installed on the inner surface of the roller and form a 90-degree angle with the central axis of the roller.

[0004] The above patent document discloses a new dental pad laminating roller, which can solve the problem that the dental pad laminating machines currently on the market are small cold-pressed laminating devices, the laminating effect is not ideal, the plastic film cannot be completely bonded to the paper product, resulting in poor quality of the dental pads shipped out of the factory. However, the disadvantage is that the roller is heated by four heating rods, which cannot heat the roller evenly, and the heat at different positions on the surface of the roller is different, which affects the laminating of the dental pad. In addition, when the existing heating roller is damaged, it is inconvenient to disassemble it and inspect the inside.

[0005] Therefore, we make improvements to this and propose a dental pad coating heating roller. Utility Model Content

The first spring 404 inside the first slide groove 401 can support the connecting rod 403 by its own elastic force, and the limiting plate 402 inside the first slide groove 401 can limit the connecting rod 403.

[0036] refer to Figure 1 - Figure 4 On the basis of the above embodiment, the drum body 1 can be easily disassembled. The present embodiment provides the following design:

[0037] As a preferred embodiment, second slide grooves 406 are provided on both side surfaces of the axis 2, and the second slide grooves 406 are connected to the first slide grooves 401. The second slide grooves 406 are internally slidably connected with a sliding rod 407, and the sliding rod 407 is located at one end of the first slide groove 401 and is inclined.

The polytetrafluoroethylene coating layer 602 coated on the outer surface of the graphene coating layer 601 is made of polytetrafluoroethylene, which has good high temperature resistance, wear resistance and anti-sticking properties, thereby preventing the film from adhering to the surface of the roller body 1 during the coating process.

[0048] Specifically, the working principle of this solution is:

[0049] When in use, the heating tube 503 is started. Since the heating tube 503 is spirally arranged, it can be evenly heated through the heat-conducting ring 502.
