Description
Technical Field
[0001] This utility model relates to the field of paper cutting technology, and in particular to a paper cutting fixing and clamping device. Background Technology
[0002] Paper cutting plays a crucial role in the printing and office equipment industries. As a key step in pre-binding processing, its cutting accuracy and efficiency have a decisive impact on the quality of subsequent processes. In particular, in the core step of paper fixing and clamping, existing fixing and clamping devices have gradually revealed a series of obvious limitations and technical problems when handling paper of different thicknesses and sizes.
[0003] Utility model patent CN209851010U discloses a paper cutting device for printing plants, including a cutting base, a cutting frame on the outer side of the cutting base, a hydraulic telescopic rod fixedly connected to the top of the inner side of the cutting frame, and a connecting block fixedly connected to the bottom end of the hydraulic telescopic rod. This utility model allows for the replacement and matching of the pressure plate and the weight block through a threaded connection, based on the required paper size. The cutting device is adjusted to a pre-cutting position between the support blocks using a fixing device. The hydraulic telescopic rod moves the connecting block downwards, and the weight of the weight block and the supporting force of the cutting base compress the paper, allowing the cutting device to cut it. This utility model eliminates the need to adjust the compression height of the pressing structure, automatically adjusting the compression according to the paper thickness, thus simplifying operation and increasing cutting efficiency. However, in actual operation, existing paper cutting devices still have significant shortcomings. In particular, the lack of an effective fixing and pressing structure during paper cutting makes the paper prone to displacement or shifting, affecting cutting accuracy and consistency.
[0004] Specifically, existing fixed clamping devices exhibit problems such as uneven clamping force and poor adaptability when facing the demands of high-volume, high-precision production. On the one hand, the design of the contact surface between the pressure plate and the paper is relatively simple, making it difficult to effectively handle paper materials of different textures and thicknesses. On the other hand, the clamping process lacks dynamic adjustment capabilities, failing to automatically adjust the clamping force according to changes in the height of the paper stack, easily causing damage to the paper surface or incomplete clamping. Furthermore, some devices require manual intervention during the clamping process, which is complex and time-consuming, reducing overall work efficiency. Therefore, to address the numerous shortcomings of existing technologies, there is an urgent need for an innovative paper cutting and fixed clamping device. Utility Model Content
[0005] The purpose of this utility model is to provide a paper cutting and clamping device, which solves the problems of the existing technology where the design of the contact surface between the plate and the paper is relatively simple, making it difficult to effectively cope with paper materials of different materials and thicknesses, and the clamping process lacks dynamic adjustment function, and cannot automatically adjust the clamping force according to the change of the height of the paper stack, which easily causes damage to the paper surface or insufficient clamping.
[0006] To achieve the above objectives, this utility model provides a paper cutting fixing and clamping device, including a frame, and an inner frame fixedly connected to the inner side of the frame, and a bearing plate slidably connected to both sides of the inner side of the inner frame.
[0007] Both support plates are fixedly connected to the bottom of the two support plates, and both sides of the top of the two support plates are provided with support rods. The bottom ends of the four support rods pass through the two support plates respectively. The bottom ends of the four support rods are fixedly connected to the first pressure plate. The top ends of the four support rods are elastically connected to the top of the two support plates respectively. A cylinder is fixedly connected to the top of the frame by bolts. A cutting plate is provided on one side of the inner middle of the frame. The output shaft of the cylinder passes through the top of the frame and is fixedly connected to the top of the cutting plate.
[0008] Each of the two limiting plates has a threaded rod on one side of its top, and the bottom end of the threaded rod passes through the limiting plate through a threaded groove. A second pressure plate is fixedly connected to the bottom end of the threaded rod.
[0009] Each of the two support plates has a slider fixedly connected to one side, and both sliders are slidably connected to the inner wall of the inner frame through a groove.
[0010] Each of the two support plates has a vertical rod fixedly connected to one side of its bottom, and the bottom ends of the two vertical rods are slidably connected to the bottom of the inner side of the frame through a movable groove.
[0011] One side of the frame is fixedly connected to a side plate, and the other side of the cut plate is fixedly connected to a sliding block, which is slidably connected to the side plate through a sliding groove.
[0012] Each of the four support rods is fitted with a tension spring, and the top of each of the four support rods is elastically connected to the top of the limiting plate through the tension spring.
[0013] This utility model discloses a paper-cutting fixing and clamping device. Through the elastic connection design of the first pressure plate and the support rod, it can automatically adapt to paper materials of different thicknesses, maintaining a good clamping effect while avoiding damage to the paper surface due to excessive pressure. This solves the problem of uneven clamping force in traditional clamping devices when dealing with paper of different thicknesses. Secondly, the second pressure plate can be manually adjusted via a threaded rod, which can provide additional reinforcement to the upper part of the paper, effectively preventing misalignment or displacement of the paper due to uneven force during the cutting process, thus compensating for the lack of multi-point clamping function in existing devices. Thirdly, the sliding adjustment design of the support plate within the inner frame allows the device to flexibly adapt to various paper sizes, improving the versatility and applicability of the equipment and overcoming the poor adaptability of existing devices. Finally, the entire clamping and cutting action is completed by a mechanical structure, eliminating the need for frequent manual intervention, improving work efficiency, reducing operational complexity, and lowering manual adjustment costs. It also helps to improve cutting consistency and yield, meeting the actual needs of high-precision and high-efficiency paper cutting in modern printing and office scenarios.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0022] Please see Figure 1-5 A paper cutting and clamping device includes a frame 1, an inner frame 2 fixedly connected to the inner side of the frame 1, and a bearing plate 3 slidably connected to both sides of the inner side of the inner frame 2; a limiting plate 13 fixedly connected to the bottom of each of the two bearing plates 3, and a support rod 14 provided on both sides of the top of each of the two limiting plates 13, with the bottom ends of the four support rods 14 passing through the two limiting plates 13 respectively, and a first pressure plate 17 fixedly connected to the bottom ends of each of the four support rods 14, with the top ends of the four support rods 14 elastically connected to the tops of the two limiting plates 13 respectively; a cylinder 9 fixedly connected to one side of the top of the frame 1 by bolts, and a cutting plate 8 provided on one side of the inner middle of the frame 1, with the output shaft of the cylinder 9 fixedly connected between the top of the frame 1 and the top of the cutting plate 8.
[0023] First, the paper to be cut is placed inside the frame 1. The inner frame 2 provides initial positioning and guidance for the paper, ensuring that the paper is stacked neatly. Then, the support rods 14 on both sides of the top of the limiting plate 13 move the first pressure plate 17 downward under elastic action, applying initial clamping force to the paper to prevent it from shifting or shaking during subsequent cutting. At the same time, to further improve the clamping effect, the operator can manually rotate the threaded rod 16 to move the second pressure plate 18 downward along the thread direction, thereby clamping the upper part of the paper a second time and enhancing the overall fixing strength. In addition, the two support plates 3 can slide and adjust inside the inner frame 2 to adjust the lateral position according to the actual size of the paper, so as to adapt to paper of different widths. After the paper is fully clamped and fixed, the cylinder 9 is activated, and its output shaft pushes the cutting plate 8 downward to complete the cutting action of the paper. The whole process is compact and easy to operate.
[0024] Furthermore, each of the two limiting plates 13 is provided with a threaded rod 16 on one side of its top, and the bottom end of the threaded rod 16 passes through the limiting plate 13 through a threaded groove. A second pressure plate 18 is fixedly connected to the bottom end of the threaded rod 16. The operator can manually rotate the threaded rod 16 to move the second pressure plate 18 downward along the thread direction, thereby pressing the upper part of the paper a second time, which achieves the effect of enhancing the overall fixing strength and effectively prevents the paper from being misaligned or shifted due to uneven force during the cutting process.
[0025] Furthermore, each of the two support plates 3 is fixedly connected to one side of a slider 4, and both sliders 4 are slidably connected to the inner wall of the inner frame 2 through a slide groove 5. When placing paper, the distance between the two support plates 3 is adjusted according to the actual size of the paper. The lateral position is precisely adjusted by sliding the slider 4 in the slide groove 5, which meets the needs of paper of different widths and improves the versatility and applicability of the equipment.
[0026] Furthermore, vertical rods 6 are fixedly connected to one side of the bottom of both support plates 3, and the bottom ends of both vertical rods 6 are slidably connected to the bottom inner side of the frame 1 through movable grooves 7. When the position of the support plate 3 is adjusted to accommodate different sizes of paper, the vertical rods 6 slide in the movable grooves 7 to provide stable support, ensuring the stability and smoothness of the support plate 3 during movement, thereby improving the overall structural stability of the device and avoiding cutting deviations caused by unstable support of the paper.
[0027] Furthermore, a side plate 10 is fixedly connected to one side of the frame 1, and a sliding block 11 is fixedly connected to one side of the cutting plate 8. The sliding block 11 is slidably connected to the side plate 10 through the sliding groove 12. When the cylinder 9 is started to drive the cutting plate 8 to move downward for cutting, the sliding block 11 slides up and down along the sliding groove 12, ensuring the vertical and stable cutting action of the cutting plate 8, thereby improving the cutting accuracy and consistency, and solving the problem of tool shaking that may occur in the cutting process of traditional devices.
[0028] Furthermore, each of the four support rods 14 is fitted with a tension spring 15, and the top of each of the four support rods 14 is elastically connected to the top of the limiting plate 13 through the tension spring 15. With the top of each of the four support rods 14 elastically connected to the top of the limiting plate 13 through the tension spring 15, the first pressure plate 17 automatically adapts to the paper thickness for initial pressing under the elastic action of the support rods 14. Utilizing the elastic force provided by the tension spring 15, the first pressure plate 17 can flexibly and automatically adjust the pressing force according to the stacking height of the paper, achieving the purpose of ensuring the pressing effect while avoiding damage to the paper surface, thus solving the problem of difficulty in accurately controlling the pressing force in the prior art.
[0029] In summary:
[0030] First, the paper to be cut is placed inside frame 1. The inner frame 2 provides initial positioning and guidance for the paper, ensuring neat stacking. Then, the support rods 14 on both sides of the top of the limiting plate 13, under elastic action, move the first pressure plate 17 downwards, applying initial pressure to the paper to prevent it from shifting or shaking during subsequent cutting. This process relies on the elastic force provided by the tension spring 15, allowing the first pressure plate 17 to automatically adjust the pressure according to the paper thickness, thus avoiding damage to the paper surface due to excessive pressure or instability due to insufficient pressure. Simultaneously, to further improve the pressing effect, the operator can manually rotate the threaded rod 16, causing the second pressure plate 18 to move downwards along the thread direction, thereby providing secondary pressure to the upper part of the paper, enhancing overall fixing strength and effectively preventing uneven force on the paper during cutting. The paper may be misaligned or shifted. Furthermore, the two support plates 3 can be slidably adjusted inside the inner frame 2. Specifically, the slider 4 slides within the slide groove 5 to achieve precise lateral position adjustment, thus adapting to paper of different widths and improving the equipment's versatility and applicability. Simultaneously, the vertical rod 6 connected to the bottom of the support plate 3 slides within the movable groove 7, providing stable support for the support plate 3 and ensuring its stability during adjustment, preventing cutting deviations due to unstable support. Once the paper is fully pressed and fixed, the cylinder 9 is activated, and its output shaft pushes the cutting plate 8 downwards to complete the cutting action. A sliding block 11 is provided on one side of the cutting plate 8, which is slidably connected to the side plate 10 via the sliding groove 12, ensuring a vertically stable cutting action for the cutting plate 8, improving cutting accuracy and consistency. The entire process is compact, easy to operate, and highly automated. First, the inner frame 2 provides initial positioning and guidance for the paper, improving the accuracy of paper placement and reducing the time and error rate of manual adjustments. Second, the elastic connection design between the first pressure plate 17, the support rod 14, and the tension spring 15 automatically adapts to paper materials of different thicknesses, maintaining a good clamping effect while avoiding damage to the paper surface due to excessive pressure, thus solving the problem of uneven clamping force in traditional clamping devices when dealing with paper of different thicknesses. Third, the cooperation between the threaded rod 16 and the second pressure plate 18 achieves secondary clamping of the upper part of the paper, enhancing the overall fixing strength and effectively preventing uneven force on the paper during the cutting process. The resulting misalignment or offset issues compensate for the lack of multi-point clamping function in existing devices. In addition, the sliding connection design between slider 4 and slide groove 5, and the auxiliary support structure between vertical rod 6 and movable groove 7, together realize the flexible adjustment and stable support of bearing plate 3, enabling the device to adapt to various sizes of paper, improving the versatility and applicability of the equipment, and improving cutting stability. Finally, the cutting plate 8 is guided by the sliding block 11 and sliding groove 12 on the side plate 10, ensuring the verticality and stability of the cutting process, improving cutting accuracy and consistency, and solving the problem of reduced cutting quality caused by blade wobbling in traditional devices.In summary, this device not only improves the efficiency and quality of paper cutting, but also effectively reduces the frequency of manual intervention and debugging costs, meeting the actual needs of modern printing and office scenarios for high-precision and high-efficiency paper cutting, and has good application prospects and promotion value.
