[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] Example: Figure 1-Figure 3 As shown, this embodiment provides a coating machine roller structure, including a mounting shaft 1 and a metering roller 2; the mounting shaft 1 has an integrally formed reinforcing shaft 11 as a bushing of the mounting shaft 1, and the axis of the reinforcing shaft 11 coincides with the axis of the mounting shaft 1; the shaft diameter of the reinforcing shaft 11 is larger than the shaft diameter of the mounting shaft 1; both ends of the metering roller 2 are coaxially fixedly connected to a mounting shaft 1.

[0031] With the above configuration, the reinforcing shaft 11 is used as a bushing. By integrally forming and connecting the bushing with the mounting shaft 1, the structural strength and rigidity are improved, ensuring stable operation under extreme working conditions. The structure is simple, easy to disassemble and install, and reduces maintenance difficulty and cost. After the modification in this embodiment, the shaft head and bushing become one piece, forming the reinforcing shaft 11 structure, preventing cracking under high-intensity operation and ensuring the stability and wear resistance of the shaft head.

[0032] In this embodiment of a coating machine roller structure, the mounting shaft 1 has an integrally formed connecting section 12, and one end of the metering roller 2 is fixedly sleeved on the outside of the connecting section 12. This configuration results in a simple structure, stable connection, and convenient assembly.

[0033] In a coating machine roller structure of this embodiment, the connecting section 12 and the metering roller 2 are fixedly connected by several sets of radial reinforcing ribs 3, which are circumferentially distributed in the annular space between the connecting section 12 and the metering roller 2. This arrangement, using reinforcing ribs to connect the metering roller 2 and the connecting section 12, results in a simple structure with high strength.

[0034] In this embodiment of a coating machine roller structure, several sets of radial reinforcing ribs 3 are evenly distributed circumferentially on the outer peripheral wall of the connecting section 12. This arrangement improves the uniformity of force distribution between the connecting section 12 and the metering roller 2, resulting in smoother operation.

[0035] In a coating machine roller structure of this embodiment, several sets of radial reinforcing ribs 3 include several outer reinforcing ribs 31 and several inner reinforcing ribs 32 integrally formed with the connecting section 12. The several outer reinforcing ribs 31 are circumferentially distributed on the connecting section 12, and the several outer reinforcing ribs 31 are close to one end of the connecting section 12. The several inner reinforcing ribs 32 are circumferentially distributed on the connecting section 12, and the several inner reinforcing ribs 32 are close to the other end of the connecting section 12. This arrangement, through the cooperation of the inner reinforcing ribs 32 and the outer reinforcing ribs 31, improves the connection stability between the connecting section 12 and the metering roller 2, and the structure is simple.

[0036] In the roller structure of a coating machine according to this embodiment, the outer reinforcing rib 31 and the inner reinforcing rib 32 are spaced apart in the axial direction. This arrangement saves materials and facilitates processing.

[0037] In one embodiment of the coating machine roller structure, as an alternative, the plurality of radial reinforcing ribs 3 may further include a plurality of reinforcing rib rods 33 and a plurality of reinforcing rib plates 34. The plurality of reinforcing rib rods 33 are integrally formed with the connecting section 12, and are circumferentially distributed on the connecting section 12, with one end of each reinforcing rib rod near the connecting section 12. The plurality of reinforcing rib plates 34 are circumferentially distributed on the connecting section 12, and are fixedly connected to the metering roller 2 and the connecting section 12. The length direction of the reinforcing rib plates 34 is consistent with the axial direction of the mounting shaft 1. With this arrangement, the reinforcing rib rods 33 and reinforcing rib plates 34 work together to provide good connection and support for the connecting section 12 and the metering roller 2.

[0038] In this embodiment of a coating machine roller structure, one end of the reinforcing rib plate 34 is fixedly connected to the side wall of the reinforcing rib rod 33 in a one-to-one correspondence. This arrangement improves the installation stability and structural strength of the reinforcing rib plate 34 and the reinforcing rib rod 33, reduces the risk of deformation, and extends the service life of the roller structure.

[0039] In a coating machine roller structure according to this embodiment, the surface of the reinforcing shaft 11 or the surface of the mounting shaft 1 has a wear-resistant coating. This configuration improves the surface hardness and wear resistance of the reinforcing shaft 11 or the mounting shaft 1. Optionally, the coating can be a nano-coating or a ceramic coating to further enhance the surface properties of the mounting shaft 1.

[0040] In this embodiment of a coating machine roller structure, the mounting shaft 1 passes through the metering roller 2, and reinforcing shafts 11 are integrally formed at both ends of the mounting shaft 1 located on the metering roller 2. This arrangement ensures the coaxiality of the metering roller 2 and the mounting shaft 1, making it less prone to breakage and improving its service life.

[0041] This embodiment of a coating machine roller structure achieves a comprehensive upgrade of the shaft head through structural optimization, surface treatment, and process improvement. In terms of structural optimization, the shaft head structure is redesigned, adopting an integrated structure where the mounting shaft 1 and the bushing are integrally formed, i.e., strengthening the shaft 11, improving overall strength and rigidity, and eliminating stress concentration points. The fit dimensions and tolerances between the shaft head and bearings and seals are optimized to ensure assembly accuracy and sealing effect. Regarding surface treatment, nano-coating or ceramic coating technology is used to further improve the surface hardness and wear resistance of the shaft head. In terms of process improvement, advanced processing techniques, such as precision casting and CNC machining, are introduced to improve machining accuracy and surface quality, and quality inspection and control are strengthened to ensure that the modified shaft head meets design requirements.

[0042] The implementation steps of a coating machine roller structure in this embodiment are as follows:

[0043] 1. Material procurement and processing: Processing and production according to the design plan.

[0044] 2. On-site installation and commissioning: Replace and install the shaft head during downtime, and conduct equipment commissioning and trial operation.

[0045] 3. Performance evaluation and summary: Conduct a performance evaluation of the modified shaft head, summarize the experience and lessons learned from the modification, and provide a reference for subsequent work.
