The drawback of this technical solution is that the limiting distance adjustment method requires multiple points to be adjusted one by one, resulting in a cumbersome and inefficient limiting method.

[0004] In summary, the existing limiting structure has the drawback of low efficiency in adjusting the paper's position. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing limiting structures in terms of low efficiency in paper limiting adjustment, and provides a limiting structure for a cross-cutting machine that improves the efficiency of limiting adjustment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A limiting structure for a cross-cutting machine, including The feeding plate is equipped with a guide hole, and the guide hole is movably connected to a moving rod; A limiting platform is placed above the feeding plate and is connected to one end of the moving rod. A support screw is connected to the bottom of the feeding plate. A support platform is sleeved on the support screw. A connecting rod is rotatably connected to the support platform. The connecting rod is rotatably connected to the other end of the moving rod. Adjustable pitch gear, which is threadedly connected to the support screw; The limit bracket has a support screw inserted into it, and the support platform and the adjustable gear are placed inside the limit bracket. The limit adjustment rod is connected to the fixed block on the feeding plate. One end of the limit adjustment rod is threaded to the fixed block, and the other end of the limit adjustment rod is connected to the adjustment rack, which meshes with the pitch gear. The finishing roller and the limiting platform are connected to a fixed bracket. The finishing roller and the fixed bracket are rotatably connected, and the fixed bracket is movably connected to a limiting ruler.

[0007] The feeding plate uses guide holes to limit the reciprocating movement of the moving rod, which in turn guides the movement of the limiting platform connected to the moving rod on the feeding plate. Several limiting platforms are symmetrically arranged on both sides of the feeding plate to support the sorting rollers on the fixed bracket, which clamp and limit the paper on the feeding plate surface. A support screw is connected to the lower end of the feeding plate, and the support platform is sleeved on the support screw. The adjustable gear can move up and down along the support screw during rotation, which allows the connecting rod to move the limiting platforms on both sides outward or inward synchronously to achieve the spacing between the limiting platforms (sorting rollers). The limiting adjustment rod, supported by the fixed block, can rotate the adjustable gear through the meshing of the rack, which can quickly and conveniently adjust the spacing between the limiting platforms to clamp the paper. At the same time, the limiting adjustment rod and the fixed block are threaded to improve the adjustment accuracy and stability and prevent paper deviation. The limiting ruler is movably connected to the fixed bracket to facilitate quick and approximate positioning of the sorting roller and shorten the debugging time of the limiting structure. This achieves the effect of improving the cross-cutting machine's high stability in paper positioning, as well as its high efficiency and precision in positioning operations.

[0008] Preferably, the guide slide hole has a limiting groove on its wall, and a limiting plate is connected to the moving rod. The limiting plate is slidably connected to the limiting groove.

The upper and lower horizontal plates, connected by the vertical plate, clamp the support platform and the adjusting gear from both sides, ensuring that the support platform always moves synchronously with the adjusting gear and preventing disengagement. This achieves the effect of ensuring the synchronization and stability of the limiting bracket's movement with respect to the limiting structure.

[0011] Preferably, the lower end face of the feed plate is connected to a guide seat, which has a limiting groove. The adjusting rack is slidably connected to the limiting groove. The feed plate, through the lower guide seat, ensures that the adjusting rack maintains meshing contact with the adjusting gear within the limiting groove, preventing disengagement. This improves the assembly stability of the limiting structure.

[0012] Preferably, the limit adjustment rod includes a main rod and a support rod. One end of the support rod is connected to the adjusting rack, and the other end is connected to the assembly plate. One end of the main rod is connected to the assembly plate, and the other end is threadedly connected to the fixing block. The main rod and the support rod are connected by the assembly plate, which allows for the installation of multiple limit stages and improves the synchronization of operations on each limit stage. This achieves the effect of improving the connection and operational stability of the limit structure.

[0013] Preferably, the fixed bracket includes a lower frame and an upper frame plate. The lower frame is connected to the limiting platform and has a positioning hole 1.

The other end of the sorting roller is connected to a positioning rod 2, which is inserted into the positioning hole 2. The sorting roller is inserted into the lower frame via the positioning rod 1 and can rotate, and is inserted into the upper frame plate via the positioning rod 2. The bolted connection between the lower frame and the upper frame plate fixes the sorting roller, thus stabilizing the connection and facilitating maintenance and replacement. This achieves the effect of improving the connection stability of the sorting roller and facilitating loading, unloading, and maintenance.

[0014] Preferably, the upper frame plate is provided with a placement hole, and the limit ruler is connected to a placement rod. The placement rod is inserted into the placement hole, and the limit ruler is rotatably connected to the upper frame plate through the placement rod. The upper frame plate is connected to the placement rod of the limit ruler through the placement hole, allowing the limit ruler to be directly rotated for use. This achieves the effect of convenient placement, replacement, and measurement use of the limit ruler.
