Technical Field
[0001] This utility model relates to the field of packaging paper box production technology, specifically a cutting device for packaging paper box raw material paper. Background Technology
[0002] A cardboard box is a box used to package goods, and it is mainly made of cardboard.
[0003] Before being formed, packaging boxes are usually made from a single piece of cardboard, which is raw paper. The raw paper often needs to be cut into appropriate sizes for subsequent production.
[0004] A Chinese patent application (CN202222150654.5) discloses a paper cutter for packaging cartons, which includes: "A base, on the surface of which two sets of symmetrically arranged side plates are fixedly connected. A threaded rod is rotatably connected between the two sets of side plates. The threaded rod passes through and is threadedly connected to the side wall of the mounting base. An electric telescopic rod is fixedly connected to the bottom surface of the mounting base. A mounting plate is fixedly connected to the bottom surface of the electric telescopic rod. An inlet and outlet are opened on the bottom surface of the mounting plate. This paper cutter for packaging cartons uses the electric telescopic rod to drive the mounting plate downwards. The pressure plate contacts the cartons and fixes both sides of the cutting line, causing the pressure plate to contract into the cylinder under pressure. One set of piston plates presses against another set of piston plates, causing a connecting plate to extend from the end of the cylinder. The two sets of connecting plates move towards each other under air pressure, driving a slider to press against an inclined plate, thereby exposing the cutting blade from the outlet. This cuts the packaging cartons while fixing them in place."
[0005] The aforementioned retrieval technology enables the cutting of raw paper for packaging boxes, but in our actual simulation, we found that this method still has certain shortcomings:
[0006] Since the raw paper needs to be cut into suitable and uniform shapes, the above-mentioned technology uses the method of placing the raw paper directly on the base and then cutting it. This makes it inconvenient to accurately position the cutting position of the raw paper, resulting in dimensional deviations in the cut cardboard, which is not conducive to the cardboard being used for subsequent production. At the same time, after cutting, manual unloading of the cut paper may be required. Manual operation poses safety hazards from the cutting blade and requires a lot of time and physical strength. Therefore, in response to the technical problems of the above-mentioned existing technology, we have designed a cutting device for packaging cardboard raw paper. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-7A cutting device for paper as raw material for packaging boxes includes a cutting table 1. A positioning plate 2 is fixed to one side of the top of the cutting table 1. A closing groove 201 is opened on the inner wall of one side of the positioning plate 2. A moving plate 14 is arranged inside the closing groove 201. A receiving block 15 is fixed on both the left and right sides of the bottom surface of the moving plate 14. A receiving block 26, driven by a servo motor 12 and moving longitudinally on the cutting table 1, is fixed in the middle of the bottom surface of the moving plate 14. A support frame 6 is also fixed to the top of the cutting table 1. A fixing plate 4 is fixed to one side of the support frame 6. A movable plate 7 driven by a cylinder 8 is slidably connected between the support frame 6 and the fixing plate 4. A cutting blade 702 is installed at the bottom of the movable plate 7. U-shaped brackets are fixed on both sides of the movable plate 7. Two telescopic components 9 are respectively arranged on each U-shaped bracket. A pressing plate 10 is arranged at the bottom of the two telescopic components 9 located on the same U-shaped bracket. The U-shaped brackets are used to support and fix the telescopic components 9 to ensure the stability of the telescopic components 9.
[0031] Please see Figure 2 and Figure 3 In this embodiment, the top of the cutting table 1 has two slide grooves 101 and one slide groove 102. Two receiving blocks 15 are slidably connected in the two slide grooves 101 and are flush with the top surface of the cutting table 1. The receiving block 2 16 is slidably connected in the slide groove 2 102 and is flush with the top surface of the cutting table 1. The bottom of the receiving block 2 16 is fixed with a toothed plate 1601.
[0032] Specifically, the receiving block 15 slides in the slide groove 101. One purpose is to facilitate the receiving of the two sides of the bottom of the paper by the receiving block 15, and the other purpose is to improve the stability of the moving plate 14 during movement. The receiving block 16 slides in the slide groove 102. One purpose is to support the middle of the bottom of the paper, and the other purpose is to facilitate cooperation with the servo motor 12 to drive the moving plate 14 to move.
[0033] Please see Figure 6 and Figure 7 In this embodiment, the servo motor 12 is installed on one side of the cutting table 1. The power output shaft of the servo motor 12 moves through the cutting table 1 and is fixed with a drive gear 13. The top of the drive gear 13 meshes with the toothed plate 1601. The drive gear 13 is located in the cavity opened inside the cutting table 1. The top of the cavity is connected to the slide groove 102.
[0034] Specifically, when the servo motor 12 drives the drive gear 13 to rotate, since the drive gear 13 meshes with the toothed plate 1601, it can drive the toothed plate 1601 and the second receiving block 16 to move in the second slide groove 102, thereby driving the moving plate 14 and the first receiving block 15 to move, so as to achieve the effect of exporting the cut paper.
[0035] Please see Figure 1and Figure 4 In this embodiment, guide grooves 11 of the same size and height are provided on one side of the support frame 6 and one side of the fixed plate 4. Guide sliders 701 are fixed on the other two sides of the movable plate 7. The guide sliders 701 are slidably connected in the guide grooves 11. The cylinder 8 is installed at the top center of the support frame 6 and the power output shaft of the cylinder 8 moves through the support frame 6 and is fixed at the top center of the movable plate 7.
[0036] Specifically, when the movable plate 7 is driven by the cylinder 8, the two sides of the movable plate 7 slide in the guide groove 11 using the guide slider 701, thereby increasing the stability of the movable plate 7 during movement. At the same time, the top two sides of the movable plate 7 are fixed with stabilizing rods of the movable through support frame 6, which can further improve the stability of the movable plate 7 during movement and ensure that the cutting blade 702 can stably cut the paper.
[0037] Please see Figure 1 and Figure 2 In this embodiment, the positioning plate 2 is L-shaped, and one side wall of the positioning plate 2 is fixedly connected to the side wall of the support frame 6. The side of the positioning plate 2 with the movable plate 14 is flush with the side of the support frame 6 with the guide groove 11.
[0038] Specifically, the L-shaped positioning plate 2 can position and flatten two sides (the two sides forming a right angle) of the stacked paper to ensure the stability of the entire stack of paper and facilitate subsequent direct cutting. One side of the positioning plate 2 is flush with one side of the support frame 6, which makes it easy for the paper to slide directly to the side of the positioning plate 2 after passing one side of the support frame 6 when it is pushed in.
[0039] Please see Figure 1 and Figure 5 In this embodiment, a fixing block 3 is fixed to the top of one side of the fixing plate 4, and the side of the fixing block 3 away from the fixing plate 4 is fixed to the positioning plate 2. A support plate 5 is fixed to the bottom of one side of the fixing plate 4, and the bottom of the support plate 5 is fixed to the top of the cutting table 1. An avoidance area is formed between the bottom of the fixing plate 4 and one side of the support plate 5.
[0040] Specifically, the fixed block 3 and the support plate 5 are designed to provide stable support for the fixed plate 4, ensuring that the movable plate 7 slides stably on the fixed plate 4. The bottom of the fixed plate 4 and one side of the support plate 5 form an avoidance area, which facilitates the paper output after cutting and avoids obstructing the paper.
[0041] Please see Figure 4 and Figure 6In this embodiment, the telescopic component 9 includes a fixed cylinder 901, a sliding rod 902, a sliding plate 903, and a return spring 904. The fixed cylinder 901 is fixed to the bottom of the U-shaped bracket. The sliding rod 902 is placed in the fixed cylinder 901 and its top moves through the U-shaped bracket. The sliding plate 903 is slidably connected inside the fixed cylinder 901 and fixedly sleeved with the sliding rod 902. The return spring 904 is sleeved on the sliding rod 902 and its bottom is fixedly connected to the sliding plate 903, and its top is fixedly connected to the inner top wall of the fixed cylinder 901. The bottom of the sliding rod 902 moves through the fixed cylinder 901 and is fixedly connected to the pressure plate 10.
[0042] Specifically, when the pressing plate 10 contacts the paper and presses down continuously, the force generated can act on the sliding rod 902. The sliding rod 902 moves upward, causing the sliding plate 903 to slide upward in the fixed cylinder 901 and compress the return spring 904. The restoring force of the return spring 904 acts on the pressing plate 10, thereby giving the paper a downward pressure, stabilizing the paper, and facilitating subsequent cutting.
[0043] Please see Figure 4 and Figure 6 In this embodiment, the height of the clamping plate 10 is lower than the height of the cutting blade 702, and the length of the cutting blade 702 is the same as the length of the movable plate 7.
[0044] Specifically, the height of the clamping plate 10 is lower than the height of the cutting blade 702. This is to facilitate the clamping plate 10 to contact and clamp the paper first, and then the cutting blade 702 cuts the paper. The length of the cutting blade 702 is the same as the length of the movable plate 7, which ensures that the cutting length is sufficiently utilized.
[0045] When in use, the staff first pushes the stacked paper to be cut along the inner side of the support frame 6 (the side with the guide groove 11). One side of the paper can slide along the inner wall of the support frame 6 to the positioning plate 2, and then slide along the inner wall of the positioning plate 2 (the side with the moving plate 14) until the other side of the paper contacts the other inner wall of the positioning plate 2 (the side facing the cutting blade 702). At this time, the paper is positioned, that is, the two sides of the stacked paper are respectively attached to the two sides of the inner wall of the positioning plate 2.
[0046] When cylinder 8 is activated, the power output shaft of cylinder 8 pushes the movable plate 7 to descend. Movable plate 7 drives telescopic component 9 and cutting blade 702 to descend. The pressure plate 10 at the bottom of telescopic component 9 will contact the paper before cutting blade 702 and use pressure plate 10 to press the stacked paper to achieve stability. Then cutting blade 702 contacts the paper and cuts the stacked paper. After cutting, cylinder 8 drives movable plate 7 to rise, so that telescopic component 9 and cutting blade 702 are away from the paper again.
[0047] The servo motor 12 is started, and the power output shaft of the servo motor 12 rotates, driving the drive gear 13 to rotate. The rotation of the drive gear 13 drives the meshing toothed plate 1601 to move, which in turn drives the receiving block 16 to move. The receiving block 16 then drives the moving plate 14 to move. When the moving plate 14 moves, it can push the cut paper to move. The receiving block 15 and the receiving block 16 receive the paper, allowing the cut paper to be discharged from one side of the cutting table 1, making it convenient for the staff to pick up the material and move it away from the cutting blade 702. After the cut paper is removed, the servo motor 12 is started to make the moving plate 14 close back into the closing groove 201 (the forward and reverse rotation of the drive gear 13 can be achieved by the forward and reverse rotation of the servo motor 12). Finally, the staff can continue to push the paper to be cut into the positioning plate 2 and complete the subsequent cutting in the manner mentioned above.
[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
