Description

Technical Field

[0001] This utility model relates to the field of paper production and processing technology, and in particular to a smooth paper feeding guide wheel. Background Technology

[0002] During the paper feeding process, it is difficult to ensure the straightening force of the paper when feeding between long-distance feed rollers. If the force is too large, it will damage the paper, and if the force is too small, the flatness of the paper cannot be guaranteed. The existing paper feeding uses guide rollers. Since the cylindrical surface of the guide roller is in direct contact with the overall plane of the paper, the force of the paper is relatively large when they are in contact. Therefore, it needs to be used as an active roller, which results in a relatively high cost. Utility Model Content

[0003] The purpose of this invention is to provide a smooth paper guide roller that can be combined with a freely rotating connecting shaft during use. Through its protruding circumferentially distributed guide structure, it achieves intermittent paper guiding during paper transport. This allows for driven paper guiding during the paper feeding process, saving power costs. Furthermore, the intermittent paper guiding during the paper feeding process creates a more uniform paper flattening force, enabling a tensioning stroke during paper transport. This avoids the direct, full contact of existing rollers, which can easily cause excessive tension and damage to the paper, thus improving the smoothness and safety of paper handling.

[0004] The technical solution of this utility model is as follows: A smooth-flowing paper guide roller includes a cylindrical main guide roller with its central axis pointing left and right. The main guide roller has a cylindrical integral mounting hole extending through its entire length at its central axis. The roller is characterized by: symmetrical limiting and reinforcing grooves extending through its entire length on both the front and rear sides of the integral mounting hole; the limiting and reinforcing grooves have a U-shaped cross-section, with the openings of the U-shape facing the central axis of the integral mounting hole; two cylindrical main guide rollers distributed left and right on its outer cylindrical surface; these main guide rollers are movable and adjustable relative to the central axis of the main guide roller; and evenly distributed arc-shaped guide conveying rollers with their central axes aligned with the central axis of the main guide roller are located on the outer cylindrical surface of each main guide roller, with the height of the guide conveying rollers extending beyond the outer cylindrical surface of the main guide rollers being less than 0.5 mm.

[0005] Furthermore, the main guide mating post is combined with the outer cylindrical surface of the main guide mating roller through a threaded engagement.

[0006] Furthermore, the length of the guide conveying mating post in the left-right direction is less than the thickness of the main guide mating post in the left-right direction.

[0007] Furthermore, the outer edge of the guide conveying mating column is provided with a safety rounded corner to avoid misalignment.

[0008] Furthermore, the minimum adjustable distance between the two main guide mating columns on the left and right is less than one-third of the total length of the main guide mating roller in the left and right direction.

[0009] The beneficial effects of this utility model are: This invention can be combined with a freely rotating connecting shaft during use. Through the protruding circumferentially distributed guiding structure, it achieves intermittent paper guiding during paper feeding. This allows for driven paper guiding during paper transport, saving power costs. Furthermore, the intermittent paper guiding during paper feeding creates a more uniform paper flattening force, ensuring a tensioning stroke during paper transport. This avoids the direct, full contact of existing rollers, which can easily cause excessive tension and damage to the paper, thus improving the smoothness and safety of paper feeding.

[0011] like Figures 1 to 7As shown, a smooth-flowing paper guide roller includes a cylindrical main guide roller 1 with its central axis pointing left to right. The main guide roller 1 has a cylindrical integral mounting hole 2 extending through its entire length at its central axis, allowing it to engage with a self-rotating shaft. During use, it can rotate freely under the action of paper feeding, achieving smooth paper flow. This free rotation enables a driven engagement, avoiding the paper damage that can occur with existing methods during active rotation. Symmetrical limiting and reinforcing grooves 3 extending through the entire length are provided on both the front and rear sides of the integral mounting hole 2, improving stability during installation. The limiting and reinforcing groove 3 has a U-shaped cross-section, with its opening facing the central axis of the integral mounting hole 2. This facilitates installation, improves stability when engaging with the self-rotating shaft, and enhances overall rotational safety, preventing loosening and idle rotation of the guide roller. The outer cylindrical surface of the main guide roller 1 is provided with two cylindrical main guide rollers 4 distributed left and right. The main guide rollers 4 can be moved and adjusted relative to the central axis of the main guide roller 1. During use, the position can be adjusted as needed to meet the paper feeding guidance of paper products of different widths, which is more flexible in use than existing guide rollers. The outer cylindrical surface of the main guide rollers 4 is provided with arc-shaped guide conveying rollers 5 that are evenly distributed around the circumference and whose central axis is the same as that of the main guide rollers 4. These are the main positions for cooperating with the paper. During the conveying process, the paper is fed through contact with these structures to achieve paper feeding and ensure the flatness of the paper. The height of the guide conveying rollers 5 extending beyond the outer cylindrical surface of the main guide rollers 4 is less than 0.5 mm. If the height is too large, it will affect the paper, such as causing indentations. When in use, it can be combined with a freely rotating connecting shaft. During paper feeding and guiding, the protruding circumferentially distributed guiding structure enables intermittent paper feeding and guiding. It can perform driven paper feeding and guiding during the paper conveying process, which not only saves power costs, but also creates a more uniform paper flattening force during intermittent paper feeding and guiding. This allows for a tensioning stroke during the paper conveying and tightening process, avoiding the excessive tension damage to the paper that can easily occur with the existing rollers that make full contact. This improves the smoothness and safety of paper feeding.

[0012] Preferably, the main guide mating column 4 is combined with the outer cylindrical surface of the main guide mating roller 1 through a threaded engagement, which provides better stability during assembly and allows for position adjustment as needed during use, thereby meeting the mating requirements for feeding paper of different widths and enhancing convenience during use.

[0013] Preferably, the length of the guide conveying mating column 5 in the left-right direction is less than the thickness of the main guide mating column 4 in the left-right direction, so that there is a certain space at both ends and more space at the edge during use, resulting in better smoothness when mating with paper.

[0014] Preferably, the outer edge of the guide conveying mating column 5 is provided with a safety rounded corner to avoid direct contact between the sharp edge and the paper, thus ensuring better safety during mating.

[0015] Preferably, the minimum adjustable distance between the two main guide columns 4 is less than one-third of the total length of the main guide roller 1 in the left and right directions. This ensures that the overall paper-cooperating range is larger during use. However, if the distance is too small, it will lead to resource waste and over-processing during production, resulting in some structures not being used. This ensures that the overall production cost is relatively low.

[0016] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
