[0002] Staples are often used to organize paper documents. Staples are used to neatly bind documents together to ensure that they will not be scattered or lost, making it easier to archive large amounts of documents.
[0003] At present, the production process of staplers usually includes the following steps: raw material pressing, gluing, punching and cutting, flipping and stacking, and packaging. In order to ensure that both ends of the stapler have good penetration when in use, so that it can penetrate paper documents more easily and efficiently, the stapler cutter is generally set to an inclined cutting angle in the punching and cutting process, so that the two ends of the cut stapler have a certain inclination.
[0004] However, in the existing production process of staplers, the cutter of the stapler mainly plays a cutting role, and the accuracy of its inclined cutting at both ends of the stapler is poor, resulting in the stapler still not having good penetration. When stapling paper documents with a harder texture or a large number of sheets, it is necessary to spend a lot of effort to press the stapler to staple the stapler, making the binding operation inconvenient, time-consuming and labor-intensive.

They do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.
[0029] like Figures 1 to 9 As shown, a staple cutting device includes a platform 1, on which a lower plate 11 and an upper plate 12 are relatively distributed up and down, and the lower plate 11 and the upper plate 12 are fixedly and spaced apart on the platform 1, and a channel 13 for a staple belt 5 to pass through is formed between the lower plate 11 and the upper plate 12, and the staple belt 5 is transported toward the lower plate 11 and the upper plate 12 from the front-to-back direction.
[0030] refer to Figure 3 to Figure 5 As shown, the two ends of the lower plate 11 are respectively provided with limiting plates 14 located on both sides of the stapler belt 5, and the number of the limiting plates 14 is four and they are relatively distributed at the two ends of the lower plate 11, and the conveyed stapler belt 5 is limited by the two limiting plates 14, and the two limiting plates 14 are relatively provided with guiding inclined surfaces 141, and the inclined surfaces 141 provide guidance for the stapler belt 5 to smoothly pass through the two limiting plates 14, so that the conveying of the stapler belt 5 is more reliable.
[0031] The platform 1 is provided with a forming assembly 3 , which includes an extrusion plate 31 and a driving member 33 . The driving member 33 may be a hydraulic cylinder, and the extrusion plate 31 is driven to move up and down by the driving member 33 .
[0032] A cutting assembly 2 is installed on the platform 1, and the cutting assembly 2 is installed on the top plate 15 of the platform 1. The cutting assembly 2 includes a driving member 22 and a cutter 21. The driving member 22 can be a cylinder. The driving member 22 drives the cutter 21 to move downward and cut the stapler belt 5. Specifically, one side of the extrusion plate 31 is provided with cutters 21 staggered up and down, that is, the cutter 21 moves downward and cooperates with the extrusion plate 31 to cut off the stapler belt 5 at the upper end of the extrusion plate 31.
[0033] The platform 1 is provided with a through hole 16 corresponding to the extrusion plate 31 , and the extrusion plate 31 passes through the through hole 16 upwardly. The upper end surface of the extrusion plate 31 is flush with or slightly lower than the upper end surface of the lower plate 11 to avoid interference of the extrusion plate 31 with the conveyance of the stapler belt 5 .
[0034] refer to Figure 6 As shown, the two ends of the lower plate 11 are provided with extrusion plates 31 that can be displaced upward, that is, the two extrusion plates 31 are distributed at the two ends of the lower plate 11, and the extrusion plates 31 can be moved upward by the driving member 33 and squeeze the two ends of the cut stapler belt 5, and then the extrusion plates 31 cooperate with the lower plate 11 to extrude the cut stapler belt 5 into a U-shaped stapler. After the extrusion forming, the extrusion plates 31 are displaced downward to reset to avoid interference with the subsequent grinding of the two ends of the stapler.
[0035] Furthermore, an upwardly extending baffle 32 is provided on the extrusion plate 31, and the baffle 32 and the cutter 21 are respectively distributed in a one-to-one correspondence with the two extrusion plates 31, and the baffle 32 is used to limit the distance of the conveyed stapler belt 5, that is, the baffle 32 cooperates with the cutter 21 to control the length of the cut stapler belt 5.
[0036] References Figure 7 to Figure 9 As shown, a grinding assembly 4 is installed on the top plate 15, and the grinding assembly 4 includes a grinding plate 41. The grinding plate 41 is arranged at both ends of the upper plate 12 and can be displaced downward. The extrusion plate 31 and the grinding plate 41 are arranged between two limit plates 14 on the same side, and the extrusion plates 31 and the grinding plates 41 are distributed relatively up and down.
[0037] Specifically, the upper plate 12 is fixedly installed on the platform 1, a slide plate 42 is slidably installed on the upper plate 12, a guide rod 43 penetrating the slide plate 42 is installed on the upper plate 12, the slide plate 42 moves up and down relative to the upper plate 12 through the guide rod 43, the two grinding plates 41 are respectively installed at both ends of the slide plate 42, and the grinding plates 41 and the extrusion plate 31 are arranged opposite to each other up and down.
[0038] Furthermore, a spring 44 is sleeved on the guide rod 43, one end of the spring 44 is fixed to the slide plate 42, and the other end of the spring 44 is fixed to the upper plate 12. A mounting plate 46 extending downward is installed on the top plate 15, and a driving member 47 is installed on the mounting plate 46. The driving member 47 can be a motor, and the output end of the driving member 47 is connected to a cam 45, and the cam 45 abuts against the upper end surface of the slide plate 42.
[0039] The cam 45 is driven to rotate by the driving member 47, so that the cam 45 can press down the slide plate 42 at intervals, and when the cam 45 presses down the slide plate 42, the grinding plate 41 can move downward and cooperate with the upper plate 12 to grind the two ends of the stapler so that the two ends of the stapler have better sharpness, thereby improving the penetration force of the stapler when in use, ensuring that it can penetrate paper documents more labor-savingly and conveniently, so as to achieve the effect of convenient binding.
[0040] And when the convex part of the cam 45 does not press the slide plate 42, the grinding plate 41 can be displaced upward under the action of the spring 44 and then move downward under the pulling force of the spring 44 to grind the two ends of the stapler again. That is, the cam 45 presses the slide plate 42 once, and the slide plate 42 can move up and down many times under the elastic force and pulling force of the spring 44, so that the grinding plate 41 can grind the two ends of the stapler many times, which greatly improves the grinding efficiency of the stapler and improves the sharpness of the two ends of the stapler.
[0041] The top plate 15 is provided with a notch 151 for avoiding the protrusion of the cam 45 , so as to prevent the top plate 15 from interfering with the rotation of the cam 45 .
