Description

Technical Field

[0001] This application relates to the field of coating equipment, and in particular to a composite coating equipment based on dual-roller differential speed control. Background Technology

[0002] Coating equipment plays a crucial role in industrial production, widely used for surface treatment of various materials such as metals, wood, and plastics to improve product appearance, corrosion resistance, and durability. As manufacturing demands for product quality continue to rise, the precision and efficiency of coating processes have become a focus of industry attention. While traditional coating technologies can meet basic painting needs, they often struggle to achieve efficient and uniform coating results when dealing with complex workpieces and multi-layer coating processes. Furthermore, paint waste and environmental pollution are becoming increasingly prominent issues.

[0003] In existing technologies, to address the issues of uniformity and efficiency in the coating process, a single hydraulic roller or oil film roller is typically used for coating, or a protective cover is added to reduce paint splatter. Furthermore, some equipment utilizes manual adjustment or simple mechanical structures to adjust the oil film thickness to adapt to different coating requirements. However, these methods generally have certain limitations. For example, a single hydraulic roller cannot simultaneously coat both the topcoat and backcoat, while manual adjustment methods lack precision and efficiency, failing to meet the demands of modern industry for high precision and automation.

[0004] When using the above-mentioned conventional methods to handle double-sided coating tasks, there is a common problem that paint may remain on the oil film roller, resulting in uneven coating. Utility Model Content

The rotation of the first hydraulic roller 111 and the second hydraulic roller 121 applies paint to the surface, and the rotation of the first oil film roller 112 and the second oil film roller 122 coats the workpiece surface with paint. By providing a slide 7 below the topcoat section 11, when the equipment is working, the slide 7 drives the topcoat section 11 closer to the sample feeding roller 2 to achieve the paint coating operation.

[0045] refer to Figures 1-2 The composite coating equipment based on dual-roller differential speed control also includes an oil film adjusting device 5. The oil film adjusting device 5 can adjust the adjustable gaps 6 formed between the first hydraulic roller 111 and the first oil film roller 112, and between the second hydraulic roller 121 and the second oil film roller 122.

[0050] refer to Figures 4-5 The difference between this embodiment and the previous one is that the oil film adjusting device 5 further includes a cylinder 52, a guide rod 53, and a support block 54. Specifically, the first oil film roller 112 and the second oil film roller 122 are connected to the cylinder 52, the cylinder 52 is connected to the guide rod 53, and the guide rod 53 is connected to the support block 54. The first oil film roller 112 and the second oil film roller 122 are placed on the support block 54. The cylinder 52 drives the first oil film roller 112 and the second oil film roller 122 to move along the guide rod 53, forming an adjustable gap 6 with the first hydraulic roller 111 and the second hydraulic roller 121.

[0051] The principle of this embodiment is as follows: the cooperation of cylinder 52, guide rod 53 and bearing block 54 forms adjustable gaps 6 between the first hydraulic roller 111 and the first oil film roller 112, and between the second hydraulic roller 121 and the second oil film roller 122. The adjustable gaps 6 ensure the thickness of the oil film and achieve different working requirements.
