Description

Technical Field

[0001] The present application relates to the technical field of paper cutters, and in particular to a paper cutter capable of recycling waste paper. Background Art

[0002] Paper cutters are important equipment for paper processing and are widely used in the printing industry. However, a large amount of scraps will be generated during the cutting process. If these scraps are not collected and processed in time, it will cause chaos in the production environment and waste of resources. Existing scrap collection methods mostly rely on manual regular cleaning and collection, but this method not only takes up a lot of manpower, but also has low collection efficiency. Therefore, a paper cutter that can recycle waste paper is proposed. Utility Model Content

[0003] In response to the shortcomings of the prior art, the present application provides a paper cutter that can recycle waste paper, which has the advantages of easy cleaning, etc., and solves the problem that the scrap collection method mostly relies on manual regular cleaning and collection, but this method not only takes up a lot of manpower, but also has low collection efficiency.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a paper cutter for recyclable waste paper, comprising a workbench, wherein the lower end of the workbench is fixedly connected to four legs distributed in a matrix array, a gantry is fixedly connected to one side of the upper end of the workbench, an electric cylinder is fixedly connected to the upper end of the gantry, the telescopic end of the electric cylinder extends into the interior of the gantry and is fixedly connected to a cutter mounting frame, a rack is fixedly connected to one end of the surface of the cutter mounting frame, a mounting column is rotatably connected to the upper end of the inner wall of one side of the gantry, a first synchronous wheel is fixedly connected to the middle of the mounting column, a gear corresponding to the rack is fixedly connected to one end of the mounting column, and the gear is meshed with the rack.

[0005] A placement groove is provided at one end of the workbench, a driven roller is rotatably connected to one side of the placement groove, a connecting frame is fixedly connected to the end of the workbench close to the placement groove, an active roller is rotatably connected to the inside of the connecting frame, a conveyor belt is commonly sleeved on the surfaces of the active roller and the driven roller, one end of the active roller extends out of the connecting frame and is fixedly connected to a second synchronous wheel, and a synchronous belt is commonly sleeved on the surfaces of the second synchronous wheel and the first synchronous wheel.

[0006] Through the above scheme, a rack is provided on the surface of one end of the cutter mounting frame, and the rack is meshed with the gear. When in use, the electric cylinder is started to drive the cutter downward to cut the paper and drive the rack to move downward. At this time, the upper end of the rack contacts the gear, and then the scraps will fall to the upper end of the conveyor belt. Then, the electric cylinder is started to drive the cutter mounting frame and the cutter to move upward and the rack will move upward synchronously. Because the rack is meshed with the gear, it will drive the gear to rotate counterclockwise and drive the first synchronous wheel on the same mounting column as the gear to rotate counterclockwise. Then the first synchronous wheel drives the second synchronous wheel to rotate through the synchronous belt, and the active roller will rotate synchronously at the same time, and then drive the conveyor belt to move in the opposite direction of the cutter, thereby driving the waste paper on the conveyor belt to move until the waste paper falls. There is no need for staff to manually clean up the waste paper, which saves manpower and improves work efficiency.

[0007] Furthermore, a cutter is fixedly connected to the lower end of the cutter mounting frame, and two guide columns distributed in a mirror image are fixedly connected to the upper end of the cutter mounting frame. The upper ends of the two guide columns extend out of the gantry and are slidably connected to the inside of the gantry.

[0008] Through the above solution, by providing two guide posts, it can be ensured that when the cutter cuts the paper, it always maintains a position perpendicular to the paper, which can further improve the cutting quality of the paper cutter.

[0009] Furthermore, a mounting groove is provided inside the workbench, a threaded rod is rotatably connected inside the mounting groove, a limit plate is threadedly connected outside the threaded rod, and a lower end of the limit plate is slidably connected to an inner wall of the mounting groove.

[0010] Through the above solution, when in use, the threaded rod is rotated according to different paper lengths, which drives the limiting plate to move, thereby accurately limiting the length of the cut portion of the paper.

[0011] Furthermore, a handle is rotatably connected to one end of the workbench, and the handle extends into the mounting groove and is fixedly connected to one end of the threaded rod.

[0012] According to the above solution, the handle is rotated to drive the threaded rod to rotate, and then the limit plate is driven to move to adjust the position of the limit plate.

[0013] Furthermore, two mirror-distributed slide grooves are provided inside the workbench, and sliders are slidably connected inside the two slide grooves. The surfaces of the two sliders are slidably connected to the inner walls of the slide grooves respectively, and the upper ends of the two sliders are fixedly connected to positioning plates.

[0014] With the above solution, by providing two positioning plates that are distributed in a mirror image, the position of the paper can be limited during the cutting process, thereby making the position of the paper more accurate.

[0015] Furthermore, a placement rack is fixedly connected to a position corresponding to the slide groove at the lower end of the workbench, and a bidirectional screw rod is rotatably connected inside the placement rack. The two sliding blocks respectively penetrate the slide groove and are threadedly connected to both ends of the bidirectional screw rod. One end of the bidirectional screw rod penetrates one end of the placement rack and is fixedly connected to a rotating handle.

[0016] Through the above solution, turning the rotating handle will drive the bidirectional screw to rotate, thereby driving the two sliders to move in opposite directions in the two slide grooves, further changing the distance between the two positioning plates.

[0017] Furthermore, two of the four legs are fixedly connected to the surfaces of the legs close to the gantry frame, and a collection box is slidably connected to the interior of the support frame.

[0018] Through the above solution, the waste paper dropped from the conveyor belt will fall into the collection box. When the collection box is full of waste paper, the collection box can be taken out from the support frame for cleaning.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] The paper cutter capable of recycling waste paper has a rack arranged on the surface of one end of a cutter mounting frame, the rack meshes with a gear, when in use, the electric cylinder is started to drive the cutter downward to cut the paper and drive the rack downward, at which time the upper end of the rack contacts the gear, and the scraps fall to the upper end of the conveyor belt, and then the electric cylinder is started to drive the cutter mounting frame and the cutter to move upward, and the rack moves upward synchronously, because the rack meshes with the gear, so the gear is driven to rotate counterclockwise, and the first synchronous wheel on the same mounting column as the gear is driven to rotate counterclockwise, and then the first synchronous wheel drives the second synchronous wheel to rotate through the synchronous belt, and the active roller rotates synchronously, and then drives the conveyor belt to move in the opposite direction of the cutter, thereby driving the waste paper on the conveyor belt to move until the waste paper falls into the collection box, and the staff does not need to manually clean the waste paper, which saves manpower and improves work efficiency.

[0034] See also Figure 1 Two of the four legs 2 are close to the gantry 3 and are fixedly connected to a support frame 28. A collection box 29 is slidably connected inside the support frame 28. Waste paper falling from the conveyor belt 16 will fall into the collection box 29. When the waste paper inside the collection box 29 is full, the collection box 29 can be taken out from the support frame 28 for cleaning.

[0035] In this embodiment, the electric cylinder 4 is started to drive the cutter 5 downward to cut the paper and drive the rack 8 to move downward. At this time, the upper end of the rack 8 contacts the gear 11, and then the scraps will fall to the upper end of the conveyor belt 16. Then the electric cylinder 4 is started, and the electric cylinder 4 will drive the cutter mounting frame 7 and the cutter 5 to move upward. At the same time, the rack 8 will move upward synchronously. Because the rack 8 is meshed with the gear 11, it will drive the gear 11 to rotate counterclockwise and drive the first synchronous wheel 10 on the same mounting column 9 as the gear 11 to rotate counterclockwise. Then the first synchronous wheel 10 drives the second synchronous wheel 30 to rotate through the synchronous belt 17. At the same time, the active roller 15 will rotate synchronously, and then drive the conveyor belt 16 to move in the opposite direction of the cutter 5, thereby driving the waste paper on the conveyor belt 16 to move until the waste paper falls into the collection box 29. There is no need for staff to manually clean up the waste paper, which saves manpower and improves work efficiency.

[0036] The working principle of the above embodiment is:

[0037] First, place the paper to be cut on the workbench 1, and adjust the distance between the two positioning plates 24 according to the size of the paper. By turning the rotating handle 27, the bidirectional screw rod 26 is driven to rotate, so that the two sliders 23 move in the slide groove 22, thereby adjusting the position of the positioning plate 24 to ensure that the paper is accurately positioned. Next, start the electric cylinder 4, and the telescopic end of the electric cylinder 4 begins to extend, driving the cutter mounting frame 7 and the cutter 5 fixed at its lower end to move downward. Since a rack 8 is fixed on the surface of the cutter mounting frame 7, and the rack 8 is meshed with the gear 11, the rack 8 will also move downward synchronously during the downward movement of the cutter 5. When the cutter 5 contacts the paper and cuts it, the upper end of the rack 8 contacts the gear 11. At this time, the scraps will fall to the upper end of the conveyor belt 16.

[0038] After the cutting is completed, the telescopic end of the electric cylinder 4 begins to retract, driving the cutter mounting frame 7 and the cutter 5 to move upward. At the same time, due to the meshing relationship between the rack 8 and the gear 11, the upward movement of the rack 8 will drive the gear 11 to rotate counterclockwise. The rotation of the gear 11 further drives the first synchronous wheel 10 fixed on the same mounting column 9 to rotate counterclockwise. The first synchronous wheel 10 is connected to the second synchronous wheel 30 through the synchronous belt 17. Therefore, the rotation of the first synchronous wheel 10 will drive the second synchronous wheel 30 and the active roller 15 fixedly connected thereto to rotate synchronously. The rotation of the active roller 15 causes the conveyor belt 16 to start running and move in the opposite direction to the moving direction of the cutter 5. In this way, the waste paper on the conveyor belt 16 will be driven to move until the waste paper falls from the other end of the conveyor belt 16. After the waste paper falls, it will fall into the collection box 29 in the support frame 28. The collection box 29 is used to temporarily store waste paper. When the waste paper accumulates to a certain extent, the collection box 29 can be slid out from the inside of the support frame 28 for cleaning and processing.
