AI Technical Summary
The existing paper flattening components are not adaptable to different paper types, and cannot flexibly meet the usage needs of different paper types when the entire assembly needs to be replaced.
A paper flattening assembly was designed. By setting detachable mounting slots and mounting blocks on the frame, the rollers can be replaced and adjusted. Combined with a detachable support wheel structure, the axial and radial limits of the rollers can be achieved to adapt to the needs of different paper types.
The flattening assembly has improved its adaptability to different paper types, simplified the roller replacement process, eliminated the need to completely disassemble the assembly, and improved operational efficiency and adaptability.

Abstract
Claims
1. A paper flattening assembly characterized by, The device includes two sets of frames arranged in parallel at different heights. Each frame is equipped with horizontally arranged rollers perpendicular to the paper feeding direction. Two rollers that are adjacent in the height direction and whose projections on the horizontal plane overlap can flatten the paper sandwiched between them. Mounting slots are provided on both sides of the top surface of each frame. Bottom support wheels are provided at the bottom of each mounting slot. Mounting blocks are detachably installed within each mounting slot. A top support wheel is installed on each mounting block at the top of the mounting slot. The two ends of each roller are located between the mounting blocks and the mounting slots on both sides of the frame, and are in contact with the bottom and top support wheels. The bottom and top support wheels can axially and radially limit the movement of the rollers. The mounting blocks can be detached from the mounting slots.
2. The paper flattening assembly of claim 1, wherein, Both the mounting groove and the mounting block have two threaded holes. Two screws pass through the threaded holes on the mounting block and the mounting groove in sequence to connect the mounting groove and the mounting block. The two screws are located on both sides of the radial direction of the roller end, so as to install the roller end between the mounting groove and the mounting block.
3. The paper flattening assembly of claim 1, wherein, Both the mounting groove and the mounting block have a threaded hole on one side of the roller end. The mounting groove and the mounting block are hinged to each other on the other side of the roller end. The screw passes through the threaded hole on the mounting block and the threaded hole on the mounting groove in sequence to connect the mounting groove and the mounting block.
4. The paper flattening assembly according to claim 1, characterized in that, It also includes a vertically arranged connecting rod, and a sleeve is provided on the side of the frame. The connecting rod passes through the sleeve, and the frame can move vertically along the connecting rod. A clamping mechanism is provided on the sleeve, and the clamping mechanism can fix the frame at a set position of the connecting rod.
5. The paper flattening assembly of claim 1, wherein, The bottom support wheel and the top support wheel have the same structure, both including an expanding section and a constricted section arranged axially. The diameter of the expanding section is larger than the diameter of the constricted section. The expanding section is located at the end of the constricted section away from the roller. The sidewall of the constricted section contacts the sidewall of the roller to support and drive the roller to rotate. The side of the expanding section near the constricted section abuts against the end face of the roller to limit the roller's axial displacement.
6. The paper flattening assembly of claim 5, wherein, The expansion section of the bottom support wheel is connected to a drive shaft on the side away from the necking section. The other end of the drive shaft is connected to the mounting groove via an elastic telescopic rod. The expansion section of the top support wheel is also connected to the drive shaft on the side away from the necking section. The other end of the drive shaft is connected to the mounting block via the elastic telescopic rod. The elastic telescopic rod is perpendicular to the drive shaft, and its length can be changed so that the distance between the top support wheel and the bottom support wheel can change with the diameter of the roller end.
7. The paper flattening assembly of claim 1, wherein, At least one of the frames is connected to a connecting plate at the end in the paper conveying direction, the connecting plate having a through hole, the connecting plate being able to connect the frame to a printing press.
8. The paper flattening assembly of claim 4, wherein, The top end of the connecting rod is detachably provided with a limiting cap, which can limit the moving range of the frame on the connecting rod.
9. The paper flattening assembly of claim 1, wherein, The frame is provided with a handle on each side.
10. A printing press characterized by The printing machine body and the paper flattening assembly of any one of claims 1-9 are provided at the paper inlet of the printing machine body.
