Since printing, packaging, book binding and other production processes require paper cutters for cutting from cutting materials to printed finished products and cutting of rough copies after binding. There are many types of paper cutters on the market, and hydraulic paper cutters can cut texts on different paper materials smoothly, which is very suitable for processing documents in large quantities. Therefore, they are widely used in libraries and printing houses.

The key points of its technical solution are: it includes a cutting mechanism, a paper feeding mechanism and a workbench, the cutting mechanism includes a pulley, a metal belt knife and a support, the pulley is arranged on the support, the pulley rotates with the paper feeding direction of the workbench as the axis, wherein the metal belt knife between two pulleys vertically penetrates the workbench, the paper feeding mechanism is arranged on the workbench, the paper feeding mechanism includes a conveyor belt and multiple rollers, the multiple rollers are horizontally installed on the workbench, the rotating roller rotates with the direction perpendicular to the paper feeding direction of the workbench as the axis, and the conveyor belt is wound on the multiple rollers.

[0004] Although the above-mentioned prior art can send the cut paper away to reduce the workload, the existing paper cutter pushes the paper to be cut under the cutter during use. During this process, the two ends of the paper cannot be fixed, which will cause the paper to tilt during cutting, thereby affecting the cutting accuracy of the paper. Utility Model Content

[0005] In order to solve the technical problem that the two ends of a paper cannot be fixed, which causes the paper to tilt during cutting and further affects the cutting accuracy of the paper, the utility model provides a paper feeding mechanism for a paper cutter.

[0006] The utility model is implemented by the following technical scheme: a paper cutting machine feeding mechanism comprises a base, the bottom of the base is fixedly connected with a supporting leg, and a cutting groove is opened on the upper surface of one side of the base, the top of the base is slidably connected with a push plate, and a cylinder for driving the push plate to slide is fixedly installed on the side of the base away from the cutting groove, and a clamping mechanism for clamping paper is arranged inside the push plate, which is used to fix the paper and prevent the paper from moving during cutting.

[0007] As a further improvement of the above scheme, the clamping mechanism includes a dual-axis motor fixedly installed inside the push plate, the output ends of the dual-axis motor are fixedly connected to a screw rod rotating inside the push plate, the surface of the screw rod is meshed with a clamping plate, and a first switch for controlling the dual-axis motor is provided on the outer side of the push plate.

[0008] Through the above technical solution, the first switch controls the dual-axis motor to rotate and drive the screw to rotate, so that the clamp moves in the center, fixes and clamps the two ends of the paper, so that the paper remains limited during the cutting process, prevents the paper from tilting, and improves the cutting accuracy.

[0009] As a further improvement of the above solution, a second switch for controlling the dual-axis motor is fixedly installed inside the clamp, and a slider is slidably connected to the opposite surface of the clamp, and the inner wall of the clamp where the second switch is installed is connected to the slider via a spring.

[0010] Through the above technical solution, while the clamping plate clamps the paper, the slider is pressed into the clamping plate, so that the slider presses the second switch, causing the dual-axis motor to stop rotating and maintain the limit position.

[0011] As a further improvement of the above solution, two groups of fixing plates are fixedly connected to the upper surface of the base and located on both sides of the push plate, and guide rails are fixedly connected between the fixing plates.

[0012] As a further improvement of the above solution, fixed blocks penetrated by guide rails are fixedly connected to both sides of the push plate, and the push plate slides on the upper surface of the base through the guide rails.

[0013] Through the above technical solution, the push plate slides through the guide rail, so that it remains stable when feeding paper and prevents the paper from tilting.

[0014] As a further improvement of the above solution, a sliding groove for sliding the clamping plate is provided on the surface of the push plate, and a reinforcing plate is fixedly connected to a side of the push plate away from the clamping plate.

[0015] Through the above technical solution, the provision of the reinforcing plate improves the strength of the push plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model controls the air cylinder to push the push plate to slide on the guide rail, and pushes the paper forward a certain distance so that the paper is arranged neatly. Then the first switch controls the double-axis motor to rotate and drive the lead screw to rotate, so that the clamping plate moves in the center. While the clamping plate clamps the paper, the slider is squeezed into the clamping plate, so that the slider squeezes the second switch, so that the double-axis motor stops rotating and keeps the limit. When the control cylinder drives the push plate to continue to move forward, the paper is pushed to the cutting groove for cutting. The design can fully limit the paper, prevent the paper from being misplaced during cutting, and improve the cutting accuracy of the paper. BRIEF DESCRIPTION OF THE DRAWINGS
