[0019] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0021] In the present application, unless otherwise specified, the orientation words such as "up, down, top, bottom" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves. Similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present application.

[0022] To address the problem that existing coating machine roller assemblies cannot be used for wide foil materials, this invention provides a coating machine roller assembly and a coating machine.

[0023] like Figure 1 The coating machine roller assembly shown includes: a rotating shaft 10; a roller 30 sleeved on the outside of the rotating shaft 10; a spacer ring 20 disposed between the rotating shaft 10 and the roller 30, wherein the rotating shaft 10 is welded to the spacer ring 20 and the spacer ring 20 is welded to the roller 30, and the rotating shaft 10 drives the roller 30 to rotate synchronously through the spacer ring 20; and a coating layer 40 adhered to the outer surface of the roller 30.

[0024] This embodiment features a rotating shaft 10, a spacer ring 20, a rubber roller 30, and a rubber coating layer 40. The rotating shaft 10, serving as the power transmission component, is centrally located. The spacer ring 20 and the rubber roller 30 are sequentially fitted around the outer periphery of the rotating shaft 10. Both the spacer ring 20 and the rotating shaft 10, and the spacer ring 20 and the rubber roller 30, are welded together. This design allows the rotating shaft 10 to drive the rubber roller 30 to rotate and also strengthens the connection between the rotating shaft 10, the spacer ring 20, and the rubber roller 30, resulting in a more stable overall structure with higher strength and rigidity, suitable for wide foil materials. The rubber coating layer 40 further protects the rubber roller 30, preventing wear and tear on the coating layer 40 and extending its service life. This design improves overall structural strength, ensures structural stability during use, and helps extend service life and reduce replacement frequency.

[0025] In this embodiment, considering that the rotating shaft 10 has a certain length, the specific number of spacer rings 20 can be set as needed. When the rotating shaft 10 is short, only one spacer ring 20 can be set, while when the rotating shaft 10 is long, multiple spacer rings 20 are preferably set, and each spacer ring 20 is axially spaced between the rotating shaft 10 and the rubber roller 30. In this way, spacer rings 20 are set at multiple positions along the axial direction between the rotating shaft 10 and the rubber roller 30, which makes the connection strength between the rotating shaft 10 and the rubber roller 30 higher and improves the stability and reliability of the connection. This embodiment takes the setting of two spacer rings 20 between a single rotating shaft 10 and the rubber roller 30 as an example.

[0026] In the embodiment, the rotating shaft 10 is in the form of a stepped shaft, specifically comprising a first small-diameter section 11, a large-diameter section 12 and a second small-diameter section 13 connected in sequence in the axial direction, and a spacer ring 20 is arranged between the first small-diameter section 11 and the rubber roller 30 and between the second small-diameter section 13 and the rubber roller 30. Due to the change in diameter, a step is naturally formed between the first small-diameter section 11 and the large-diameter section 12 and between the second small-diameter section 13 and the large-diameter section 12, and the end faces of the two spacer rings 20 abut against the two steps respectively. Thus, when welding, the end faces of the spacer rings 20 can also be welded together with the step faces, thereby helping to improve the structural strength, and the formation of the step also helps to position the spacer rings 20 and ensure the accuracy of the installation position of the spacer rings 20. Of course, in addition to the three-section variable-diameter structure described above, the rotating shaft 10 can have more variable-diameter sections, and correspondingly, the number of spacer rings 20 can also be increased.

[0027] Preferably, the outer end face of at least one spacer ring 20 is flush with the end face of the rubber roller 30. For example, the end face of the first small-diameter section 11 closer to the end face of the rubber roller 30 than the second small-diameter section 13 is flush with the end face of the rubber roller 30. Figure 1 At the left end face of the rubber roller 30, the right end face of the leftmost spacer ring 20 abuts against the step face between the first small-diameter section 11 and the large-diameter section 12, and the left end face is flush with the end face of the rubber roller 30. Thus, overall, the end face of the rubber roller 30 is a relatively flat end face without obvious protrusions or recesses, thereby making the overall structure neat and helping to reduce the volume occupied.

[0028] Since the rubber roller 30 is in the form of a sleeve with openings at both ends, the rotating shaft 10 of the embodiment is also provided in multiple numbers, and the rotating shaft 10 is arranged through the rubber roller 30 at both ends. The embodiment is provided with two rotating shafts 10 arranged through the rubber roller 30 at both ends, thereby supporting the rubber roller 30 at both ends by the rotating shaft 10, and the rotation of the rubber roller 30 is more stable. Part of the two rotating shafts 10 extends out of the rubber roller 30, thereby facilitating connection and cooperation with external driving and transmission components. Correspondingly, since the rotating shaft 10 is in multiple numbers, the rubber roller 30 is provided with a spacer ring 20 between the two rotating shafts 10 at both ends. Since the embodiment is provided with two spacer rings 20 between a single rotating shaft 10 and the rubber roller 30, the embodiment is provided with four spacer rings 20, and the two spacer rings 20 are arranged between the rotating shaft 10 and the rubber roller 30 in the manner described above, which will not be described herein again.

[0029] In the embodiment, the outer surface of the rubber roller 30 has a threaded structure, and the rubber coating layer 40 is attached to the threaded structure. The threaded structure makes the attachment between the rubber coating layer 40 and the rubber roller 30 more reliable and stable, thereby ensuring the stable attachment of the rubber coating layer 40 on the peripheral side of the rubber roller 30.

[0030] In the embodiment, the thread structure includes right-handed and left-handed threads staggered at the circumferential outer surface of the rubber roller 30. In this way, by arranging the right-handed and left-handed threads simultaneously, the form of the thread structure is more diversified, thereby helping to further improve the reliability of the bonding of the rubber coating layer 40 and avoid the situation that a single form leads to partial defects. In addition to the difference in thread rotation direction, the intervals, inclination angles, etc. of the thread structures at different positions can also be arranged in different ways. At the same time, the staggered thread structure can effectively disperse the stress of the rubber roller 30 during coating and reduce the wear of the rubber roller 30, which is suitable for high-load and long-time running coating production lines, ensuring the durability and coating efficiency of the rubber roller 30.

[0031] Preferably, the rubber coating layer 40 of the embodiment is a ternary ethylene-propylene rubber layer with a hardness of Shore 78-82. As a high-performance rubber material, ternary ethylene-propylene rubber has excellent corrosion resistance and wear resistance, which is suitable for coating applications in various harsh environments, ensuring the stability and durability of the rubber coating layer 40 in different environments. At the same time, the rubber coating layer 40 of the embodiment is designed to be thick, with a single-sided thickness, that is, the thickness of one side of the circumferential two sides along the diameter direction of the rubber roller 30, being greater than or equal to 12 mm, so that the thickness of the rubber coating layer 40 is large, the wear resistance is greatly improved, and the thick design of the rubber coating layer 40 can also provide better cushioning effect, reduce vibration during coating, and be more suitable for application scenarios with high coating precision requirements, ensuring coating precision and surface quality.

[0032] The embodiment also provides a coating machine including the above-mentioned coating machine rubber roller assembly. Through the above-mentioned optimization design, the coating machine rubber roller assembly of the embodiment not only improves the running stability and coating precision of the coating machine, but also enhances the wear resistance and corrosion resistance of the rubber roller 30, ensuring the uniformity and durability during coating. Significantly improves the production efficiency and product quality of the coating machine, reduces the maintenance cost, and is suitable for various working conditions. The coating machine provided by the embodiment is efficient, stable and durable. It can meet the high requirements for coating quality, speed and equipment durability, reduce the failure rate and maintenance cost during production, and improve the production efficiency of the production line.
