[0024] like Figures 1 to 5 As shown, the utility model relates to a positioning and cutting device for a split paper cutter, comprising a paper cutter body, a processing platform is arranged on the paper cutter body, a cutter is arranged at the center of the processing platform, transverse plates 1 are arranged on both sides of the top of the processing platform, the cutter is located at the center position of the two transverse plates 1, a slider 9 is arranged at the bottom of the transverse plate 1, the processing platform is provided with a sliding groove for the slider 9 to slide, a transverse clamping plate 5 is arranged on one side of the transverse plate 1, and a movable track 3 fixed to the bottom of the processing platform is arranged between the bottoms of the two transverse plates 1.
[0025] In an embodiment of the utility model, in order to achieve lateral limiting, a screw rod structure 4 for driving the transverse plate 1 to move toward each other is installed on the movable track 3, and the screw rod structure 4 includes opposing screw rods 401 and two nut seats 402. The ends of the opposing screw rods 401 are connected to a driving structure. In this design, the driving structure adopts a reversible driving motor. The opposing screw rods 401 are rotatably connected to the inside of the movable track 3, and the spirals at both ends of the opposing screw rods 401 are structures with opposite directions. The two nut seats 402 are fixed to the corresponding sliders 9 and are slidably connected to the movable track 3. The spiral structure with opposite directions allows the two nut seats 402 to move closer to or away from each other.
[0026] In the embodiment of the utility model, in order to achieve vertical limiting, a stacked airbag 10 with folded wrinkles is fixed between the transverse plate 1 and the transverse clamping plate 5, vertical clamping plates 7 are provided on both sides of the transverse clamping plate 5, and pneumatic structures 8 are connected to both ends of the transverse clamping plate 5. The pneumatic structure 8 includes a cylinder sleeve 801 and a piston rod 802 that are mortise and tenoned to each other, a piston 803 is provided at the end of the piston rod 802, and a compression spring 804 is provided on one side of the piston 803 around the piston rod 802, a pressure relief hole is provided at one end of the cylinder sleeve 801 away from the extension plate 805, and the pneumatic structure 8 also includes an extension plate 805, which connects the transverse clamping plate 5 and the cylinder sleeve 801, and a stacked airbag with folded wrinkles is fixed between the transverse plate 1 and the transverse clamping plate 5 10. An air supply channel 806 connected to the cylinder sleeve 801 is provided between the stacked airbag 10, the transverse clamping plate 5 and the corresponding extension plate 805. When the transverse plate 1 moves to a certain extent, the stacked airbag 10 will be squeezed, so that the gas is transported to the inside of the cylinder sleeve 801 through the air supply channel 806, and the piston 803 is further pushed to move (the gas on the other side of the piston 803 is discharged through the vent hole). At this time, the compression spring 804 will be pressed to move the vertical clamping plate 7 and limit the side of the stacked paper products. When the transverse plate 1 returns to motion, the elastic restoring force of the compression spring 804 is used to separate the vertical clamping plate 7 from the stacked paper products. A spring can be set on the inner side of the stacked airbag 10 to accelerate the return of the stacked airbag 10.
[0027] In order to further adapt to the adjustment, an adjustment structure 6 is provided between the transverse clamping plate 5 and the transverse plate 1. The adjustment structure 6 includes a threaded rod 601 that cooperates with each other, a threaded portion 602 at the outer periphery of one end of the threaded rod 601, and a first constraint plate 603. The center of the first constraint plate 603 is set to be hollow, the threaded portion 602 is threadedly connected to the inner wall of the first constraint plate 603, one side of the first constraint plate 603 is fixed to the top of the transverse clamping plate 5, and a second constraint plate 604 is provided at the outer periphery of one end of the threaded rod 601. The second constraint plate 604 is slidably connected to the threaded rod 601;
[0028] It should be noted that by rotating the threaded rod 601, the threaded portion 602 can be rotated to adjust the spacing between the transverse plate 1 and the transverse clamping plate 5, thereby adjusting the starting position of the vertical clamping plate 7 to better adapt to cutting paper products of different sizes;
[0029] A boss 605 is fixed at the end of the threaded rod 601, and a ring plate 606 is connected to the central area of the threaded rod 601. A return spring 607 is arranged between the ring plate 606 and the second constraint plate 604. The boss 605 is easy to rotate. The return spring 607 is designed to drive the transverse clamping plate 5 to return to the original position when the transverse plate 1 moves outward.
[0030] Working principle: This embodiment provides a positioning and cutting device for a split paper cutter. When in use, the stacked paper products are placed in the cutting area of the paper cutter processing platform, and the driving motor is controlled by an external control structure to drive the opposite screw rods 401 to rotate, drive the two nut seats 402 to approach each other synchronously, move the transverse plate 1, move the two transverse clamping plates 5, and limit both sides of the stacked paper products;
[0031] At this time, the transverse plate 1 continues to move, so that the second restraining plate 604 squeezes the return spring 607, and at the same time, the transverse plate 1 squeezes the stacked airbag 10, so that the gas is transported to the inside of the cylinder sleeve 801 through the air supply channel 806, and further pushes the piston 803 to move, and at this time, the compression spring 804 is pressed, so that the vertical clamping plate 7 moves and limits the side of the stacked paper products;
[0032] When the limit needs to be cancelled, the control structure controls the driving motor to rotate in the opposite direction, so that the transverse plate 1 moves in the opposite direction. During the movement, the reset spring 607 and the protrusion 605 will reset the two constraint plates, and the transverse clamping plate 5 will be separated from the stacked paper products to cancel the limit. At the same time, the stacked airbag 10 will be restored, and the spring and reset spring 607 inside the stacked airbag 10 will be cooperated to make the gas reflux, so that the vertical clamping plate 7 can be separated from the stacked paper products, and the cut paper products can be taken out.
[0033] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
