[0016] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0017] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of the present specification are only used to match the contents disclosed in the specification for people familiar with the technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present utility model, should still fall within the scope of the technical contents disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in the present specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present utility model. The change or adjustment of the relative relationship, without substantial change of the technical contents, should also be regarded as the scope of the implementation of the present utility model.

[0018] Figure 1-Figure 2The main structural components of a printer heating roller are shown, including a heating roller body 1, with heat insulation sleeves 2 at both ends of the heating roller body 1, with an annular buckle 3 on the side of the heat insulation sleeve 2 away from the heating roller body 1, the annular buckle 3 is detachably connected to the heat insulation sleeve 2, a connecting column 4 is provided on the annular buckle 3, the annular buckle 3 is sleeved on the cylindrical surface of the connecting column 4, and a fixing seat 5 is provided on the connecting column 4.

[0019] The heat insulating sleeve 2 is the main indirect component of the heating roller, and is connected to the annular buckle 3 through the heat insulating sleeve 2. A symmetrically distributed arc key groove 21 is provided on a surface of the heat insulating sleeve 2 away from the heating roller body 1.

[0020] like Figure 2 As shown, the annular buckle 3 is provided with an arc key 31 adapted to the arc key groove 21, and the annular buckle 3 is connected to the arc key groove 21 through the arc key 31. The arc key 31 matches the arc key groove 21 on the heat insulating sleeve 2 to complete the positioning of the heating roller body 1, and the arc key 31 on the annular buckle 3 only needs to be inserted into the arc key groove 21.

[0021] At the same time, symmetrical fixing openings 32 are provided at both ends of the annular buckle 3 , and a clamping block 33 is provided in the fixing opening 32 .

[0022] Preferably, a fixing groove 41 matching the fixing opening 32 is provided on the connecting column 4, and the bottom end of the clamping block 33 is placed inside the fixing groove 41. When fixing the heating roller body 1, the connecting column 4 is buckled into the annular opening of the annular buckle 3 until the fixing groove 41 is aligned with the fixing opening 32. At this time, it is only necessary to insert the clamping block 33 into the fixing opening 32 and the fixing groove 41 at the same time.

[0023] Preferably, an end of the connecting column 4 away from the heating roller body 1 is provided with an external shaft 42, and the fixing seat 5 is placed on the cylindrical surface of the external shaft 42. The fixing seat 5 is provided with a bolt 51, and the fixing seat 5 is fixed to the outside world by the screw 51 to ensure that the heating roller body 1 will not deviate during operation, so as to prevent it from affecting the service life of the printer.

[0024] Compared with the traditional heating roller, the utility model can quickly position the heating roller body 1 by inserting the arc key 31 on the annular buckle 3 into the arc key groove 21 on the heat insulation sleeve 2; the annular buckle 3 and the connecting column 4 are fixed by the clamping block 33 on the annular buckle 3, and the fixing seat 5 on the external rotating shaft 42 fixes the connecting column 4 as a whole. Therefore, when the clamping block 33 is inserted into the fixing groove 41 on the connecting column 4, the heating roller body 1 will be fixed.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
