AI Technical Summary
Existing rotary screens cannot fully open the cells when printing with high mesh and wide widths. Changes in squeegee pressure and errors in the spacing between the screen circumference and the substrate cause screen deformation, affecting printing quality and causing severe squeegee wear.
The satellite-type rotary screen printing device applies tension and pull in the radial and axial directions of the annular screen through the screen support assembly and clamping assembly, so that the cells are fully opened. The squeegee pressure adjustment component reduces the pressure of the squeegee on the annular screen and avoids squeegee wear.
Ensure that the cells of the circular screen are fully open in both the circumferential and axial directions to avoid a decline in print quality, reduce squeegee wear, and improve the service life and printing effect of the printing equipment.

Abstract
Claims
1. A satellite-type rotary screen printing device, characterized in that: The device includes a screen support assembly, a screen clamping assembly mounted on the screen support assembly, and an annular wire mesh connected to the screen clamping assembly. The annular wire mesh is sleeved on the screen support assembly, which provides radial support to the annular wire mesh, allowing the mesh cells of the annular wire mesh to be fully open. The screen clamping assembly is located at both axial ends of the annular wire mesh. Driving the screen clamping assembly allows the annular wire mesh to rotate relative to the screen support assembly, and also allows for axial tensioning and axial dimension adjustment of the annular wire mesh.
2. Satellite wheel rotary screen printing apparatus according to claim 1, characterized in that: The screen support assembly includes a support component and a plurality of support rollers arranged sequentially along the circumferential direction of the annular screen, all connected to the support component. The plurality of support rollers are in contact with the annular screen and provide radial support to the annular screen. The support component is located at both ends of the plurality of support rollers, and the support rollers are rotatable relative to the support component.
3. Satellite wheel rotary screen printing apparatus according to claim 2, characterized in that: The support assembly includes a fixed support, a clamping support connected to the fixed support, and a roller support connected to the clamping support. The fixed support, the clamping support, and the roller support are coaxially arranged. The fixed support and the roller support are respectively located at both axial ends of the clamping support. The roller support is connected to a plurality of support rollers. The screen clamping assembly is rotatably mounted on the clamping support. The screen clamping assembly is connected to the fixed support, and there is a gap between the screen clamping assembly and the fixed support to allow for axial position adjustment of the screen clamping assembly.
4. Satellite wheel rotary screen printing apparatus according to claim 3, characterized in that: The screen clamping assembly includes a clamping component and a tensioning component connected to each other. The clamping component is connected to the annular screen and is rotatably mounted on the clamping support. The tensioning component is connected to the fixed support. The tensioning component drives the clamping component to move along the axial direction of the annular screen to tighten the annular screen.
5. A satellite rotary screen printing apparatus according to claim 4, wherein: The clamping assembly includes a first clamping member and a second clamping member arranged coaxially. The first clamping member and the second clamping member are fitted together and connected. The sides of the first clamping member and the second clamping member that are in contact are both inclined surfaces. The end of the annular wire mesh is located at the contact surface of the first clamping member and the second clamping member to clamp the annular wire mesh.
6. A satellite rotary screen printing apparatus according to claim 5, wherein: The outer peripheral side of the second clamping member is provided with teeth.
7. A satellite rotary screen printing apparatus according to claim 5, wherein: The tensioning assembly includes a rotating component and a tensioning component coaxially arranged. The rotating component is sleeved on the second clamping component, which has an axial limiting component that contacts the rotating component. The axial limiting component positions the rotating component as it moves along the axial direction of the annular wire mesh. The tensioning component is sleeved on the rotating component and connected to the fixed support component via the tensioning component. The tensioning component has an abutment portion that contacts the rotating component. By driving the tensioning component to move, the tensioning component is driven to move along the axial direction of the annular wire mesh, causing both the clamping assembly and the rotating component to move with the tensioning component, thus adjusting the tension of the annular wire mesh.
8. Satellite wheel rotary screen printing apparatus according to any one of claims 5-7, characterized in that: The clamping support is provided with a first groove and a second groove, which are arranged sequentially along the axial direction of the clamping support. Both the first groove and the second groove are provided with a sliding piece. The sliding piece in the first groove slides in contact with the first clamping member, and the sliding piece in the second groove slides in contact with the second clamping member.
9. A satellite rotary screen printing apparatus, characterised in that: The device includes an intermittent squeegee assembly and a satellite-type rotary screen printing apparatus as described in any one of claims 1-8. The intermittent squeegee assembly includes a squeegee component and a squeegee pressure regulating component connected to each other. The squeegee component is located inside the screen support assembly, and the squeegee pressure regulating component is located at both axial ends of the squeegee component extending to the outside of the screen support assembly. The squeegee pressure is intermittently controlled so that when the welded seam of the annular screen moves to the squeegee blade area, the pressure applied by the squeegee to the annular screen decreases, so that the annular screen separates from the bottom roller, but the squeegee does not separate from the annular screen, thereby reducing squeegee wear.
10. Satellite wheel rotary screen printing apparatus according to claim 9, characterized in that: The scraper assembly includes a scraper swing arm device and a scraper device connected together. The scraper pressure adjustment assembly includes a power component, a sliding component connected to the power component, and a rotating component. The rotating component is rotatably mounted on the scraper swing arm device. The sliding component has a sliding member that slides in contact with the rotating component. The sliding member has a protrusion. The power component drives the sliding component to rotate. When the protrusion contacts the rotating component, the scraper swing arm device rotates, causing the scraper to rotate and reducing the pressure applied by the scraper to the annular wire mesh.
11. Satellite wheel rotary screen printing apparatus according to claim 10, characterized in that: The sliding assembly includes a rotating shaft and at least two sliding members disposed on the rotating shaft. Each sliding member is in sliding contact with a corresponding rotating member, and the sliding member is a cam structure.
