Description

Technical Field

[0002] In the printing and binding industry, the paper cutter is the core equipment for paper cutting and processing, and its cutting accuracy directly determines the final quality of the printed products. Before cutting, the paper needs to be stacked on the paper cutter's worktable. If the stacked paper is misaligned, it will result in inconsistent paper sizes and uneven edges after cutting. This will not only affect the smooth progress of subsequent binding processes, but also cause paper waste and increase production costs.

[0003] A paper cutter with anti-deviation function disclosed in CN222371740U includes a cutting table and a gantry frame. A cylinder is fixedly connected to the inner side of the gantry frame, and a lifting plate is slidably connected to the inner side of the gantry frame. The top surface of the lifting plate is fixedly connected to the output shaft of the cylinder. A control unit and a pressing unit are provided on the inner side of the cutting table. Although the stacked papers can be aligned by the push plate of the control unit, the movement range of the push plate is fixed and cannot be adapted to the length, width, or other specifications of the paper. It can only adapt to one type of paper, and its application range is relatively limited. Therefore, there is an urgent need for an anti-deviation paper cutter for printing and binding.

The reinforcing ribs 15 can improve the structural strength of the connection between the paper cutter 12 and the lifting plate 4 to ensure the cutting stability of the paper cutter 12. A paper pressing mechanism 13 is provided on the lifting plate 4. A baffle 16 is fixedly provided on the inner side of the support frame 2 and is located in front of the paper cutter 12. When the paper cutter 12 is idle, the baffle 16 can protect the paper cutter 12 to prevent personnel from accidentally touching it and improve safety.

[0034] The adjustment mechanism 8 includes:

[0035] The movable block 8-1 is movably disposed in the movable groove 8-2 opened at the bottom of the extrusion rod 6. The screw 8-3 is rotatably disposed in the extrusion rod 6 through a bearing. The insertion rod 10 is rotatably sleeved on the screw 8-3 through a thread.

[0036] Spring 8-4 is fixedly installed in movable groove 8-2, and one end of spring 8-4 is fixedly connected to movable block 8-1. Movable block 8-1 is rotatably mounted with rotating cylinder 8-5 through bearing. Several drive bars 8-6 are distributed with equal rounded corners on lead screw 8-3. Drive bars 8-6 and lead screw 8-3 are movably inserted into rotating cylinder 8-5.

[0037] A rotating rod 8-7 is rotatably inserted into the movable block 8-1 via a bearing. The lower end of the rotating rod 8-7 is rotatably inserted into the side wall of the support frame 2 via a bearing. The output shaft of the motor 9 is connected to the rotating rod 8-7. The upper end of the rotating rod 8-7 is connected to the rotating cylinder 8-5 via a bevel gear pair. The adjusting mechanism 8 can adjust the distance between the contact frame 11 and the pressing rod 6 to facilitate the adjustment of the position of the contact frame 11 according to the paper specifications, thereby achieving the adaptation and alignment of various paper specifications. A synchronizing rod 14 is rotatably inserted into the base 1 via a bearing. The end of the synchronizing rod 14 is rotatably inserted into the side wall of the support frame 2 via a bearing. The lower end of the rotating rod 8-7 is connected to the synchronizing rod 14 via a bevel gear pair. The synchronizing rod 14 can realize the synchronous drive of the rotating rods 8-7 on both sides, improving the convenience of adjusting the moving position of the contact frames 11 on both sides, while also ensuring the symmetry of the positions of the contact frames 11 on both sides.

[0038] The paper pressing mechanism 13 includes:

[0039] Pressure plate 13-1 is suspended at the bottom of lifting plate 4. Vertical rods 13-2 are fixedly installed on the upper left and right sides of pressure plate 13-1. The upper end of vertical rod 13-2 passes through lifting plate 4 and is fixedly installed with limit block 13-3. Limit block 13-3 is movable and abuts against the upper part of lifting plate 4.

[0040] Two springs 13-4 are movably mounted on two vertical rods 13-2, and both ends of the springs 13-4 are fixedly connected to the pressure plate 13-1 and the lifting plate 4, respectively. The lifting plate 4 has an adapter groove 13-5 that cooperates with the abutment frame 11. After the stacked papers are aligned, the paper pressing mechanism 13 can press the papers to prevent them from shifting during the cutting process.

[0041] When using this invention, the stacked papers are placed on the upper part of the base 1, and then the hydraulic cylinder 3 is activated. The hydraulic cylinder 3 drives the lifting plate 4 to move downwards, and the lifting plate 4 drives the lifting rod 5 to move downwards. At this time, the pressing rod 6 moves under the pressure of the lifting rod 5. The pressing rod 6 drives the contact frame 11 to move towards the paper through the lead screw 8-3 and the insert rod 10, and compresses the first spring 8-4. The contact frames 11 on both sides abut against the left and right sides of the paper respectively, aligning the stacked papers. The lifting plate 4 continues to move downwards. The lifting plate 4 drives the pressure plate 13-1 to move downwards through the second spring 13-4 and the vertical rod 13-2, so that the pressure plate 13-1 abuts against the paper. As the lifting plate 4 continues to move downwards, the second spring 13-4 will be compressed. When the second spring 13-4 is compressed, it will apply a downward rebound force to the pressure plate 13-1 to press the paper tightly and prevent the paper from shifting. Then, the paper cutter 12 can cut the paper as the lifting plate 4 moves downwards.

[0042] If it is necessary to sort and align papers of different sizes, the motor 9 can be started. The motor 9 drives the rotating rod 8-7 connected to its output shaft to rotate. With the cooperation of the synchronous rod 14 and the bevel gear pair, the synchronous rotation of the lead screws 8-3 on both sides can be achieved. The rotation of the lead screws 8-3 can drive the insertion rod 10 to move, thereby adjusting the distance between the contact frame 11 and the pressing rod 6.

[0043] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0044] 1. Through the cooperation of motor 9 and adjustment mechanism 8, the distance between the contact frame 11 and the pressing rod 6 can be flexibly adjusted to adapt to different paper sizes and meet the diverse paper cutting needs of the printing and binding industry.

[0045] 2. The paper pressing mechanism 13, through the coordinated action of the pressure plate 13-1 and the second spring 13-4, can press the paper tightly before cutting. The rebound force of the second spring 13-4 can maintain the pressing state continuously, effectively preventing the paper from shifting during the cutting process, reducing paper waste caused by inconsistent cutting dimensions, and improving the cutting quality of printed materials.

[0046] 3. The synchronous rotation of the rotating rods 8-7 and lead screws 8-3 on both sides can be achieved by the synchronous rod 14, thereby realizing the symmetrical adjustment of the two sides of the contact frame 11. There is no need to manually adjust the two sides of the structure separately, which simplifies the operation process and ensures the synchronicity and symmetry of the adjustment of the two sides of the contact frame 11, further improving the stability of paper alignment and reducing manual operation error.

[0047] 4. When the paper cutter 12 is idle, the baffle 16 can effectively protect it, preventing people from being injured by accidentally touching the paper cutter 12 and improving safety.

[0048] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
