Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 、 Figure 2 and Figure 3The utility model provides an embodiment of a paper cutter with a burr trimming function, comprising a mounting member 1, a support block 2 fixedly connected to the top of the support block 2, a cylinder 10 fixedly connected to the top of the support block 2, a motor 3 fixedly connected to the outside of the support block 2, two slide rods 6 rotatably connected to the outside of the support block 2, a slide groove 7 is provided on the outside of the slide rod 6, a gear 4 is fixedly connected to the outside of the slide rod 6, the outside of the support block 2 is fixedly connected to the fixed block 9, a connecting groove 15 is provided on the bottom of the fixed block 9, a connecting block 5 is slidably connected to the outside of the connecting groove 15, a trimming knife 8 is fixedly connected to the bottom of the connecting block 5, two sliding balls 13 are fixedly connected to the outside of the connecting block 5, and an adjustment component is installed inside the mounting member 1.

[0031] Furthermore, the cylinder 10 is started, and the output end of the cylinder 10 drives the cutting knife 14 to move downward to cut the paper stack. After cutting, the motor 3 is started, and one of the slide bars 6 is driven to rotate through the output end of the motor 3. At the same time, the slide bar 6 drives one of the gears 4 to rotate at the same time. At this time, under the meshing action of one of the gears 4, the other gear 4 rotates synchronously, and then the two slide bars 6 rotate toward each other, so that the connecting block 5 slides along the inner wall of the connecting groove 15, and then drives the trimming knife 8 to move at the same time to trim the burrs of the paper stack. Trimming the burrs can make the edges of the paper more neat and smooth, thereby improving the appearance of the paper.

[0032] Reference Figure 2 、 Figure 3 and Figure 4 The adjustment component includes a second motor 16, the outside of the second motor 16 is fixedly connected to the bottom of the mounting member 1, and a receiving groove 21 is provided inside the mounting member 1. The inner wall of the receiving groove 21 is rotatably connected to a turntable 19, and the outside of the turntable 19 is rotatably connected to two moving parts 20. The inner wall of the receiving groove 21 is fixedly connected to two limit rods 18, and the outside of the limit rod 18 is slidably connected to a slider 17. The top of the slider 17 is fixedly connected to a baffle 12, and the inner side wall of the receiving groove 21 is provided with two internal grooves 11.

[0033] Furthermore, the motor 2 16 is started, and the output end of the motor 2 16 drives the turntable 19 to rotate, thereby driving the two moving parts 20 to move simultaneously. At this time, driven by the moving parts 20, the two sliders 17 slide along the outside of the limit rod 18. At the same time, the sliders 17 drive the two baffles 12 to approach each other along the inner wall of the internal groove 11, and adjust the edge of the paper stack so that the edge of the paper stack is neat. Adjusting the edge of the paper can make the cutting process smoother, reduce paper jams and malfunctions of the paper cutter, and thus improve production efficiency.

[0034] Reference Figure 1 、 Figure 2 and Figure 3The output end of the motor 3 is fixedly connected to one end of one of the slide bars 6, and the two slide slots 7 are symmetrically distributed; the outside of one of the gears 4 is meshed with the outside of the other gear 4 at the corresponding position.

[0035] Furthermore, one of the slide bars 6 is driven to rotate by the output end of the motor 1 3, and the symmetrically distributed slide grooves 7 can make the slide ball 13 slide along the two slide grooves 7, thereby making the connecting block 5 drive the trimming knife 8 to move; when one of the gears 4 rotates, the other gear 4 is driven to rotate at the same time through engagement, thereby making the two slide bars 6 rotate towards each other.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 The outside of the sliding ball 13 is slidably connected to the inner wall of the sliding groove 7; the outside of the supporting block 2 is slidably connected to the cutting knife 14.

[0037] Furthermore, when the slide bar 6 rotates, the slide ball 13 slides along the inner wall of the slide groove 7 ; the adjusted paper stack is cut by the cutter 14 .

[0039] Furthermore, the turntable 19 drives the slider 17 to slide along the outside of the limit rod 18 through the moving part 20; when the slider 17 slides, the baffle 12 slides along the inner wall of the inner groove 11, making the baffle 12 more stable when sliding, further improving the stability of the baffle 12.

[0040] Working principle: Start motor 2 16, the output end of motor 2 16 drives the turntable 19 to rotate, and then the turntable 19 drives the two sliders 17 to slide along the outside of the limit rod 18 through two moving parts 20. At the same time, the slider 17 drives the baffle 12 to slide along the inner wall of the internal groove 11, so that the two baffles 12 are close to each other, and the paper stack is adjusted so that the edges of the paper stack are neat, which is convenient for subsequent cutting.

[0041] In addition, the cylinder 10 is started, and the output end of the cylinder 10 drives the cutting knife 14 to move downward to cut the paper stack. After cutting, the motor 3 is started, and the output end of the motor 3 drives one of the slide bars 6 to rotate, and then drives one of the gears 4 to rotate at the same time. At this time, one of the gears 4 drives the other gear 4 to rotate through engagement, so that the two slide bars 6 rotate toward each other. Then, under the traction of the slide groove 7, the connecting block 5 slides along the inner wall of the connecting groove 15, and then drives the trimming knife 8 to move at the same time to trim the burrs of the paper stack. Trimming the burrs can make the edges of the paper more precise and consistent.
