Description

Technical Field

[0001] The utility model relates to a paper feeder, in particular to a conveying pressing wheel mechanism of the paper feeder. Background Art

[0002] Sheet feeders are widely used in sheet-fed printing machinery and equipment such as screen printing machines, gravure printing machines, fully automatic die-cutting machines, and paper laminating machines. A paper stacking table for placing paper piles is set at the entrance section, and the paper is separated and fed into the paper feeder table in sequence through the feeder head. As the paper is continuously output, the paper pile monitoring system of the paper feeder increases the height of the paper pile at any time to ensure uninterrupted paper feeding.

[0003] In order to ensure the stable transmission of paper on the paper feeder, the existing paper feeder has a conveying pressure wheel mechanism above the paper feeder, which presses the paper against the paper feeder through the conveying pressure wheel mechanism to increase the friction between the paper and the paper feeder, so that the paper feeder drives the paper to achieve stable transmission. The existing conveying pressure wheel mechanism includes a conveying frame, a plurality of pressure wheel groups arranged on the conveying frame, and fastening components arranged at both ends of each pressure wheel group, and the fastening components are used to fix the two ends of the pressure wheel group on the conveying frame. However, the existing fastening components are complex in structure and are used in large quantities, resulting in a high production cost of the existing fastening structure; and when adjusting the pressure wheel group, it is necessary to operate the fastening components at both ends respectively, resulting in cumbersome operation. Based on the above problems, the present invention is conceived. Utility Model Content

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a paper feeder conveying pressure wheel mechanism, including a paper pressure wheel group, which is configured to press and hold the paper in transmission and the number is set to be a plurality; a conveying frame, which is configured to install the paper pressure wheel group; and also includes: a locking assembly, which is arranged at one end of the paper pressure wheel group and is used to dock with the conveying frame; a first docking groove, which is arranged at one end of the paper pressure wheel group opposite to the locking assembly and cooperates with the locking assembly to achieve the fixation of the paper pressure wheel group and the conveying frame.

[0006] By adopting the above technical solution, the first docking groove realizes the docking of the end of the paper pressing wheel group with the conveying frame, and in the locking process of the locking assembly, the first docking groove can be used to fix the two ends of the paper pressing wheel group with the conveying frame, so as to complete the fixing operation of the paper pressing wheel group on the conveying frame. This setting structure enables a group of paper pressing wheel groups to only need one locking structure, and the adjustment operation of the paper pressing wheel group can be completed by operating one locking structure. This method has a simple structure, is easy to operate and has a lower production cost.

[0007] It is further configured as follows: the locking assembly includes a second docking groove installed on the paper pressing wheel group, the first docking groove and the second docking groove both form a docking opening for docking with the conveying frame, and the two docking openings are arranged in opposite directions.

[0008] By adopting the above technical solution, the first butt joint groove and the second butt joint groove, which are arranged opposite to each other, cooperate with each other to form a limit, so that the paper pressing wheel assembly can be stably installed on the conveying frame.

[0009] It is further configured as follows: the locking assembly includes a locking block slidably arranged on the paper pressing wheel group, a fastener arranged on the paper pressing wheel group, and a linkage structure that constitutes a linkage between the locking block and the fastener so that the fastener can drive the locking block to move away from the first docking groove, and the second docking groove is arranged on the locking block.

[0010] By adopting the above technical solution, the fastener drives the locking block through the linkage structure to drive the second docking groove to move away from the first docking groove, so as to achieve expansion and fixation. When the force acting on the locking block is released, the paper pressing wheel group and the conveying frame can be separated to achieve convenient adjustment.

[0011] It is further configured as follows: the linkage structure includes a linkage block movably arranged on the paper pressing wheel group, a linkage inclined surface formed on the linkage block, and a matching inclined surface formed on the locking block and matching the linkage inclined surface.

[0012] By adopting the above technical solution, the fastener drives the linkage block to move, and the direction of force is changed under the cooperation of the linkage inclined surface and the matching inclined surface, thereby driving the locking block to move away from the first docking groove.

[0013] It is further configured as follows: it includes an active groove formed on the linkage block, the active groove is movably matched with the paper pressing wheel group, and the paper pressing wheel group is provided with a limit block for limiting the movement of the linkage block away from the locking block. When the linkage structure is in a linkage state, the limit block cooperates with the active groove so that the linkage inclined surface always abuts against the matching inclined surface.

[0014] By adopting the above technical solution, the movable groove and the limit block cooperate with each other to limit the linkage block in the linkage, so as to realize the convenient assembly of the linkage block and the paper pressing wheel group, making the disassembly and assembly operation more convenient while ensuring the reliability of the linkage structure.

[0015] It is further configured as follows: comprising a slide groove formed on the locking block, wherein the slide groove is sleeved on one end of the paper pressing wheel assembly and slidably cooperates with the paper pressing wheel assembly.

[0016] By adopting the above technical solution, this arrangement structure realizes convenient assembly between the two while ensuring the strength of the sliding structure.

[0017] It is further configured that: the first docking groove and the second docking groove are both in a V-shape facing the docking opening.

[0018] By adopting the above technical solution, this structure can compensate for the assembly tolerance formed between the assembly components to further improve the stability of the installation.

[0019] In summary, the utility model has the following beneficial effects: the utility model has a simple structure, is easy to operate and has a lower production cost. BRIEF DESCRIPTION OF THE DRAWINGS
