[0001] This utility model belongs to the field of hole punching machines, specifically relating to a manual hole punching machine for office stationery. Background Technology

[0002] In the stationery manufacturing industry, with the booming development of the personalized stationery and high-value-added office supplies market, stationery processing enterprises have placed higher demands on the specialization of their production equipment. As a key process in stationery production, the precision, efficiency, and equipment stability of punching operations directly affect the finished product qualification rate and production line efficiency.

[0003] However, after punching, the pins often stick to the stationery due to friction. Traditional equipment only uses spring reset to remove the pins, but it cannot solve the technical problem of the document being lifted. It requires manual pressing to fix it, resulting in poor operation continuity.

[0004] Paper scraps tend to accumulate on the surface of nail holes. Existing cleaning devices mostly use a fixed scraper structure, which cannot be adapted to nail holes of different diameters. Furthermore, the cleaning components wear out severely after long-term use, resulting in a decrease in cleaning effectiveness. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of traditional punching equipment in the background art, such as the hole nail sticking to the stationery, causing the document to be easily pulled up and requiring manual secondary fixation, poor operation continuity, and the inability of fixed cleaning devices to adapt to different hole diameters, so as to realize a manual punching machine for office stationery.

[0006] To achieve the above-mentioned objectives, the technical solution of this utility model is: a manual hole punch for office stationery, comprising a base, a support rod fixed to one side of the top of the base, a lifting rod slidably connected to the support rod, a lifting plate connected to the bottom of the lifting rod, a limiting component slidably connected to the bottom of the lifting plate, and a plurality of cleaning components evenly distributed and fixed on the limiting component.

[0007] In the aforementioned manual hole punch for office stationery, a pressing rod is rotatably connected to one side of the support rod, and one end of the pressing rod is rotatably connected to the support rod via a rotating shaft.

[0008] In the aforementioned manual hole punch for office stationery, both sides of the pressing rod are rotatably connected to linkage shafts. The ends of the two linkage shafts away from the pressing rod are respectively rotatably connected to both sides of the lifting rod. Both sides of the lifting rod are slidably connected to one side of the support rod. Slider blocks are fixed on both sides of the lifting rod. The support rod has a groove for the sliding of the sliders. The bottom of the lifting rod is bolted to the top of the lifting plate.

[0009] In the aforementioned manual hole punch for office stationery, limit rods are fixed on both sides of the top of the base, and through holes for sliding of the limit rods are provided at both ends of the lifting plate. A return spring is sleeved on the limit rod, and the return spring is located between the top of the base and the lifting plate.

[0010] In the aforementioned manual hole punch for office stationery, the base has tracks fixed on both sides of its top and also includes a punching table. The punching table has grooves on both sides for sliding on the tracks, and a handrail is fixed on one side of the punching table.

[0011] In the aforementioned manual hole punch for office stationery, the limiting component includes a pressure plate and a sliding rod. The sliding rod is fixed at both ends of the top of the pressure plate, and the top of the sliding rod is threadedly connected to the limiting plate. The lifting plate has through holes at both ends for the sliding of the limiting plate.

[0012] In the aforementioned manual hole punch for office stationery, the cleaning component includes a limiting ring, a cleaning plate, a threaded rod, and a support shaft. The cleaning plate is symmetrically and slidably connected inside the limiting ring. The threaded rod is rotatably connected to the middle position of the side wall of the cleaning plate.

[0013] In the aforementioned manual hole punch for office stationery, a number of hole pins are fixed at the bottom of the lifting plate, each of the hole pins being coaxially corresponding to the limiting ring, and brush bristles for cleaning the hole pins are fixedly provided on the inner side of the cleaning plate.

[0014] Compared with the prior art, the manual hole punch for office stationery of this utility model has at least the following beneficial effects:

[0015] 1. The manual hole punch for office stationery of this utility model, by setting a limiting component with a pressure plate, uses the weight of the pressure plate itself or the counterweight design to maintain continuous pressure on the stationery the instant the hole pin is disengaged after punching, effectively reducing the problem of documents being lifted up due to friction between the hole pin and the paper in traditional hole punchers, reducing the need for manual secondary pressing operations, and significantly improving the continuity and efficiency of the punching operation.

[0016] 2.

Therefore, they should not be construed as limitations on this utility model.

[0028] This embodiment discloses a manual hole punch for office stationery. Traditional hole punching equipment suffers from drawbacks such as the hole pins sticking to the stationery, causing documents to be easily pulled up and requiring manual secondary fixation, poor operational continuity, and fixed cleaning devices being unable to adapt to different hole diameters. (Refer to...) Figures 1-5It mainly includes a base 1, a support rod 2 fixed on one side of the top of the base 1, a lifting rod 6 slidably connected to the support rod 2, a lifting plate 7 connected to the bottom of the lifting rod 6, a limiting component 9 slidably connected to the bottom of the lifting plate 7, and several cleaning components 16 evenly distributed and fixed on the limiting component 9.

[0029] A lifting rod 6 is slidably connected to the support rod 2. The lifting rod 6 can slide up and down along the axial direction of the support rod 2. This sliding connection is achieved through a groove on the support rod 2 and sliders fixed on both sides of the lifting rod 6, ensuring the stability and accuracy of the lifting rod 6 during the lifting process. A lifting plate 7 is connected to the bottom of the lifting rod 6. The lifting plate 7 is horizontally set, and its top is fixedly connected to the bottom of the lifting rod 6, so that the lifting plate 7 can move synchronously with the lifting rod 6. A limiting member 9 is slidably connected to the bottom of the lifting plate 7. The limiting member 9 can slide horizontally at the bottom of the lifting plate 7 to accommodate the punching needs of stationery of different sizes. Several cleaning members 16 are evenly distributed and fixed on the limiting member 9. The cleaning members 16 are used to clean the punched holes to prevent paper scraps from remaining and affecting the next use.

[0030] Reference Figures 1-3 A pressing rod 3 is rotatably connected to one side of the support rod 2. One end of the pressing rod 3 is rotatably connected to the support rod 2 via a rotating shaft 4. Both sides of the pressing rod 3 are rotatably connected to linkage shafts 5. The ends of the two linkage shafts 5 away from the pressing rod 3 are rotatably connected to the two sides of the lifting rod 6, respectively. The two sides of the lifting rod 6 are slidably connected to one side of the support rod 2. Slider blocks are fixed on both sides of the lifting rod 6. The support rod 2 has grooves for sliding the sliders. The bottom of the lifting rod 6 is bolted to the top of the lifting plate 7.

[0031] The driving end of the pressing rod 3 is rotated with the support rod 2 via a nested rotating shaft 4. Double linkage shafts 5 are symmetrically arranged on both sides of the pressing rod 3. Each linkage shaft 5 is connected to the pressing rod 3 and the lifting rod 6 at both ends via bearings, forming a multi-degree-of-freedom rotational connection and constituting a parallel four-bar linkage mechanism. The main body of the lifting rod 6 has an I-shaped cross-section, and its two flanges form a vertical guide pair with the dovetail-shaped groove on the inner side of the support rod 2 via embedded sliders. The bottom of the lifting rod 6 is detachably bolted to the lifting plate 7 via a flange. This split structure ensures transmission accuracy and facilitates later maintenance and replacement. When the operator presses down the pressing rod 3, the force is converted into a vertical displacement of the lifting rod 6 via the linkage shafts 5 through the lever principle, driving the lifting plate 7 to move precisely up and down along the guide mechanism. The entire transmission system, through the composite design of the four-bar linkage and sliding guide, achieves smooth transmission of drilling force and precise control of the hole position.

[0032] Reference Figures 1-3Limiting rods 8 are fixed on both sides of the top of the base 1. Through holes for sliding of the limiting rods 8 are opened at both ends of the lifting plate 7. A return spring 13 is sleeved on the limiting rod 8 and is located between the top of the base 1 and the lifting plate 7. Tracks 11 are fixed on both sides of the top of the base 1, and a drilling table 10 is also included. Grooves for sliding on the tracks 11 are opened on both sides of the drilling table 10, and a handrail 12 is fixed on one side of the drilling table 10.

[0033] The two sides of the top of the base 1 are bolted with distance limiting threaded rods 14, which can limit the lifting plate 7 when it descends, preventing the lifting plate 7 from being pressed down excessively.

[0034] A reset spring 13 is fitted in the area of ​​the limiting rod 8 between the lifting plate 7 and the base 1. The helical spring adopts a pre-compression assembly method, and its elastic coefficient is matched with the weight of the drilling component. It can provide a stable reset driving force after drilling and avoid the lifting plate 7 from generating impact vibration.

[0035] The top surface of the base 1 is also equipped with two parallel linear guide rail mechanisms, including a track 11 fixed to the base 1 and a drilling table 10 that slides with it. The track 11 has an inverted T-shaped cross-section, and the bottom of the drilling table 10 has a corresponding dovetail-shaped groove, forming a sliding pair. The operator can push or pull the handle 12 to achieve smooth movement of the drilling table 10 on the track 11. When drilling is performed, the drilling table 10 can be precisely moved along the track 11 to directly below the lifting plate 7.

[0036] Reference Figures 1-5 The limiting component 9 includes a pressure plate 901 and a sliding rod 902. The sliding rod 902 is fixed to both ends of the top of the pressure plate 901. The top of the sliding rod 902 is threadedly connected to a limiting plate 903. The lifting plate 7 has through holes at both ends for the sliding of the limiting plate 903. The cleaning component 16 includes a limiting ring 1601, a cleaning plate 1602, a threaded rod 1603, and a support shaft 1604. The cleaning plate 1602 is symmetrically slidably connected inside the limiting ring 1601. The threaded rod 1603 is rotatably connected to the middle position of the side wall of the cleaning plate 1602. The limiting ring 1601 has an internal thread for the rotation of the threaded rod 1603. The support shaft 1604 is fixed to both ends of the side wall of the cleaning plate 1602. The limiting ring 1601 has sliding holes for the sliding of the support shaft 1604. The other two sides of the limiting ring 1601 are bolted to the inner side of the pressure plate 901. The bottom of the lifting plate 7 is fixed with several pins 15, each pin 15 is coaxially corresponding to the limiting ring 1601, and the inner side of the cleaning plate 1602 is fixed with bristles for cleaning the pins 15.

[0037] When the lifting plate 7 moves downward, the pressure plate 901 contacts the stationery surface first, and the sliding rod 902 slides in the guide hole to achieve adaptive height adjustment, ensuring that stationery of different thicknesses can obtain uniform clamping force.

[0038] The cleaning component 16 adopts a modular and adjustable structure. The limiting ring 1601 is an annular base with symmetrical radial guide grooves on its inner wall. The cleaning plate 1602 forms a precise sliding fit with the limiting ring 1601 through the guide grooves. Each cleaning plate 1602 has a high-density nylon bristles arrayed on its surface, arranged radially to expand the cleaning range. The front end of the threaded rod 1603 is rotatably connected to the cleaning plate 1602 through a bearing, and its rear end is equipped with a knurled knob. The operator can drive the cleaning plate 1602 to move axially along the support shaft 1604 by rotating the threaded rod 1603. The support shaft 1604 is a smooth shaft structure, which cooperates with the linear bearing hole on the limiting ring 1601 to form a double guide support system, ensuring the smooth movement and coaxiality of the cleaning plate 1602.

[0039] The limiting ring 1601 is detachably connected to the inner side of the pressure plate 901 by bolts. Each limiting ring 1601 is coaxially aligned with the pin 15 fixed at the bottom of the lifting plate 7. After the pin 15 completes the drilling operation, it passes through the center hole of the limiting ring 1601 during the reset process. At this time, the cleaning plate 1602 uses bristles to clean the outer circumference of the pin 15, effectively removing the adhering paper fibers. By adjusting the screw depth of the threaded rod 1603, it can accommodate pins 15 of different diameters, ensuring that the bristles always maintain elastic contact with the surface of the pin 15, achieving thorough cleaning while avoiding mechanical damage to the pin 15.

[0040] The working principle of this utility model of a manual hole punch for office stationery is as follows: First, several hole pins 15 are fixed at the bottom of the lifting plate 7 according to the usage. According to the number of hole pins 15 used, corresponding limit rings 1601 are installed. The document to be punched is placed on the punching table 10 and fixed. Then, the punching table 10 is moved to the bottom of the lifting plate 7 by the handle 12. The operator pulls the pressing rod 3. By pressing down the pressing rod 3, the pressing rod 3 drives the linkage shaft 5 to move. The linkage shaft 5 drives the lifting rod 6 to descend. The lifting rod 6 slides on the support rod 2. The support rod 2 limits the sliding position of the lifting rod 6. The limit piece 9 at the bottom of the lifting plate 7 first contacts the stationery on the punching table 10. The bottom of the lifting rod 6 drives the lifting plate 7 and the hole pins 15 to move down to punch the stationery. After punching, the operator releases the pressing rod 3. The pressure of the return spring 13 pushes the lifting plate 7 to rise. The hole pins 15 first exit the stationery and pass through the limit rings 1601.

[0041] By rotating the threaded rod 1603, the threaded rod 1603 pushes the cleaning plate 1602 to move. The support shaft 1604 supports and limits the position of the cleaning plate 1602. According to the different diameters of the holes 15, the distance between the cleaning plate 1602 and the holes 15 is adjusted. The bristles on the cleaning plate 1602 clean the holes 15. After the lifting plate 7 rises to a certain distance, the holes 15 are completely detached from the stationery. When the holes 15 are detached from the stationery, the pressure plate 901 remains stationary. The pressure plate 901 can press the stationery with its own weight to prevent the stationery after drilling from rising with the holes 15. The lifting plate 7 contacts the limiting plate 903, and then the lifting plate 7 continues to rise, driving the limiting plate 903 to continue to rise. The limiting plate 903 drives the sliding rod 902 and the pressure plate 901 to rise and no longer press the stationery.
