[0023] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, the fixing module in this embodiment includes a bracket 1 and a heating roller 2 arranged on the bracket 1, and also includes a conductive component arranged at at least one end of the heating roller 2. The conductive component can be used to conduct static electricity accumulated on the heating roller 2 to the ground.

[0025] The conductive assembly is mounted on bracket 1. It includes a conductive member 3 that rotates in contact with the end of the heating roller 2, a grounding wire 4 for grounding, and a sheet metal member 5 electrically conductively disposed between the conductive member 3 and the grounding wire 4. The conductive member 3 and the heating roller 2 achieve initial contact transmission, the sheet metal member 5 forms the further transmission structure, and the grounding wire 4 enables the final discharge of static electricity to the ground. Thus, the conductive member 3, the sheet metal member 5, and the grounding wire 4 form a static grounding path, discharging static electricity accumulated during the operation of the heating roller 2 to the ground.

[0026] The heating roller 2 rotates during operation. To better achieve the conductive positional relationship between the conductive member 3 and the heating roller 2, the conductive member 3 is a sleeve mounted on the end of the heating roller 2. This sleeve has a cavity for the end of the heating roller 2 to fit into. The conductive member 3 is fixed to the bracket 1. This structure ensures that the conductive member 3 maintains a close relative conductive positional relationship even during the rotation of the heating roller 2, thereby continuously dissipating static electricity from the heating roller 2. In this embodiment, the sleeve, which serves as the conductive member 3, is C-shaped. While ensuring continuous contact between the conductive member 3 and the end of the heating roller 2, it also reduces the contact area between the heating roller 2 and the conductive member 3, thereby reducing the contact resistance between the heating roller 2 and the conductive member 3 and improving the efficiency of static electricity transmission. Furthermore, it prevents the conductive member 3 from causing excessive rotational resistance to the heating roller 2, ensuring normal rotation of the heating roller 2. Furthermore, the C-shaped conductive member 3, due to its semi-open structure, is easy to assemble.

[0027] In order to facilitate the convenient installation of the conductive component 3 on the bracket 1, an installation cavity matching the shape of the conductive component 3 is formed on the inner wall of the bracket 1, and the conductive component 3 can be assembled in the installation cavity.

[0028] Furthermore, to improve the accuracy of the installation position of the conductive member 3 within the mounting cavity of the bracket 1 and ensure the conductive positional relationship between the conductive member 3 and the heating roller 2 and the sheet metal member 5, a first limiting rib 31 and a first limiting groove 32 are provided on the outer surface of the conductive member 3. The bracket 1 is provided with a second limiting rib 111 that fits within the first limiting groove 32, and a second limiting groove 112 that fits within the first limiting rib 31. When installing the conductive member 3 on the bracket 1, the first limiting rib 31, first limiting groove 32, second limiting rib 111, and second limiting groove 112 are aligned to achieve precise positioning and assembly.

[0029] To further prevent the conductive member 3 from rotating and losing its conductive positional relationship with other components, the bracket 1 is provided with a positioning block 113. A positioning member 33 is provided on the outer surface of the conductive member 3, which abuts against the positioning block 113 to limit the circumferential rotation of the conductive member 3. When assembling the conductive member 3 on the bracket 1, aligning the positioning member 33 with the positioning block 113, combined with the relative positional relationship of the first limiting rib 31, the first limiting groove 32, the second limiting rib 111, and the second limiting groove 112, ensures the stability of the fixed position of the conductive member 3 on the bracket 1.

[0030] The sheet metal component 5 typically has excellent electrical conductivity and can quickly conduct static electricity to the ground wire 4. However, due to the limited distance between the conductive component 3 and the ground wire 4, in order to increase the conductive area, enhance the static electricity dispersion effect, and provide sufficient contact area for subsequent safe grounding, the sheet metal component 5 in this embodiment includes a first sheet metal member 51 and a second sheet metal member 52. The first sheet metal member 51 is fixed to the bracket 1 and abuts the conductive component 3. In this embodiment, the first sheet metal member 51 abuts the end face of the conductive component 3. The second sheet metal member 52 abuts the first sheet metal member 51, and the ground wire 4 is fixedly connected to the second sheet metal member 52.

[0031] In order to ensure the contact reliability between the first sheet metal 51 and the conductive member 3, and between the first sheet metal 51 and the second sheet metal 52, the first sheet metal 51 and the second sheet metal 52 in this embodiment are

[0032] Specifically, the first sheet metal component 51 includes a first body 511, a fastening member 512, and a pressing member 513 integrally connected to the first body 511. The first body 511 is clamped between the end surface of the conductive member 3 and the bracket 1, and the fastening member 512 is fastened to the bracket 1. Accordingly, a latching hole or hook structure can be provided on the bracket 1 to achieve a secure fastening with the fastening member 512, thereby reliably securing the first sheet metal component 51 to the bracket 1. In addition, the pressing member 513 is bent and connected to the first body 511, and has a tendency to press the conductive member 3. Due to the elastic characteristics of the pressing member 513, the reliability of the conductive contact between the first sheet metal component 51 and the conductive member 3 can be improved.

[0033] For easy assembly, the bracket 1 includes a first frame 11 and a second frame 12 that are relatively buckled together. The heating roller 2 is supported and arranged on the first frame 11. The conductive component 3 and the first sheet metal part 51 are arranged on the first frame 11 corresponding to the end of the heating roller 2. The second sheet metal part 52 is integrally connected to the second frame 12. The second sheet metal part 52 is bent from the second frame 12 toward the first sheet metal part 51 and rests on the first sheet metal part 51. In order to achieve the conductivity of the second sheet metal part 52, the first frame 11 in this embodiment is made of a non-conductive material, and the second frame 12 can be made of a conductive material. Of course, the second frame 12 can also be made of a non-conductive material. In this way, the second sheet metal part 52 can be fixedly connected to the second frame 12 through a connecting structure.

[0034] To improve the connection reliability between the first sheet metal member 51 and the second sheet metal member 52, the second sheet metal member 52 includes a plate-shaped second body 521 and an operating plate 522 bent from the free end of the second body 521. The operating plate 522 abuts against the first sheet metal member 51 through surface contact. The operating plate 522 increases the contact area with the first sheet metal member 51, thereby improving the reliability of the conductive contact between the first sheet metal member 51 and the second sheet metal member 52.

[0035] The fixing module of the present invention forms an electrostatic discharge path in a conductive position relationship with the heating roller 2 by providing a conductive component 3, a grounding wire 4, and a sheet metal component 5, so that static electricity is safely discharged into the ground, completing the entire electrostatic discharge process, and realizing the whole process management of static electricity from generation to safe release. At the same time, the good conductive performance of the sheet metal component 5 is utilized to quickly discharge static electricity.

[0036] This fusing module effectively solves the problem of static electricity accumulation on the heating roller 2, while also reducing burrs and static electricity cancellation caused by static electricity accumulation in the printer, significantly improving the clarity and stability of printed images. Furthermore, the fusing module prevents static electricity backflow, ensuring the safety of both equipment and personnel.

[0037] This embodiment also relates to a printer, including the aforementioned fixing module.
