Description

Technical Field

[0001] The utility model relates to the technical field of film heat treatment, in particular to a heating roller structure. Background Art

[0002] The setting of the heat treatment temperature is closely related to the thermal stability of the film. If the treatment is good, the thermal stability of the film can be greatly improved. Of course, if the treatment temperature is too high or too low, it will affect the intrinsic and apparent properties of the film. Therefore, when stretching the film, it needs to be heated to meet the thermal stability requirements. Based on the above problems, this application proposes a heating roller structure.

[0018] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] like Figure 1-2 As shown, the utility model is a heating roller structure, including a heating roller body 10 and connecting columns connected to the two ends of the heating roller body 10, a protective shell 40 is provided outside the roller body, the two ends of the protective shell 40 are sleeved on the connecting columns, and the inner wall surface of the protective shell 40 is provided with insulation material or a heating plate.

[0020] Based on the above technical solution, the connecting column in this embodiment includes a first connecting column 20 and a second connecting column 30, and corresponding connecting holes 50 are provided at both ends of the roller body. One end of the first connecting column 20 and the second connecting column 30 extends into the connecting hole 50 and is connected to the roller body, and one end of the first connecting column 20 or the second connecting column 30 is used to connect to the drive motor.

[0021] Based on the above technical solution, the protective housing 40 in this embodiment includes a body and first and second connecting plates 60 and 70 that are sleeved onto the connecting posts. The first and second connecting plates 60 and 70 are provided with sleeve holes 80 that cooperate with the first and second connecting posts 20 and 30 to mount the protective housing 40. The body has an arc-shaped cross-section and is located on either side of the roller body. This allows the protective housing 40 to be rotated to a desired position and adjusted flexibly as needed.

[0022] When the inner wall surface is provided with a heat-insulating material, the heat-insulating material is polyethylene or other materials.

[0023] When a heating plate is provided on the inner wall, the heating plate is welded to the inner wall of the protective shell 40 , and its heating temperature is consistent with the heating temperature of the roller body. The heating plate is also arc-shaped like the body.

[0024] The utility model sets a protective shell 40 on one side of the heating roller to protect the film when it is wound on the roller body. Secondly, corresponding insulation materials are set on the inner wall surface of the protective shell 40, which can heat the film when it is stretched horizontally or longitudinally to ensure the thermal stability of the surface.

[0025] In addition, the insulation material can be replaced by a heating plate, which heats the surface of the film to ensure the consistency of both sides of the film during heating.

[0026] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0027] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0028] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
