Description

Technical Field

[0001] This utility model relates to the field of office supplies technology, specifically to a multifunctional document punching device. Background Technology

[0002] When finance departments calculate and file taxes for a company, their main accounting basis is the invoices and documents issued when transactions occur. Over time, a large number of documents are generated to record various transactions and business activities. In order to better store invoices and documents for future reference and verification, it is usually necessary to punch holes in the documents to facilitate subsequent storage such as perforation and fixing. Punching and flattening machines are usually used to punch holes and flatten documents to facilitate their binding and organization.

[0003] For example, Chinese utility model application CN202323225719.9 discloses a financial management document binding device, relating to the technical field of binding devices. It includes a bottom support base and a punching operation base, with a punching mechanism positioned between them. A punching motor is housed within the operating cavity of the punching operation base, connected to the punching mechanism via a drive gear, a driven gear, and a moving rod. A clamping mechanism is located on the front side of the punching mechanism. The punching mechanism adjusts the punching spacing, and the clamping mechanism fixes the position of the document to be punched. When the device is powered on, the punching motor pushes the punching mechanism downwards to perform the punching operation. This device utilizes a cutting blade, facilitating document binding and punching operations. Simultaneously, the lower sidewall of the bottom support plate is always directly below the punching head, supporting the bottom of the document and reducing deformation during punching, ensuring smooth punching operations.

[0029] like Figures 1 to 6 As shown, this multifunctional document punching device includes a base 1, a mounting frame 2, a drive assembly 3, a punching sleeve 4, a push rod 5, and a clamping assembly 6. The bottom of the base 1 is a flat support surface. The mounting frame 2 is fixed to the base 1, providing stable support for the drive assembly 3, the punching sleeve 4, and the push rod 5. The top is slidably connected to the punching sleeve 4 to ensure its vertical and stable movement. The drive assembly 3 is connected to the mounting frame 2, and its output end is connected to the punching sleeve 4, driving it to move downwards. The base 1 is provided with a through hole 11 corresponding to the punching sleeve 4. The punching sleeve 4 is slidably connected to the mounting frame 2. The punching sleeve 4 is a hollow cylinder with a cutting edge 41 at the lower end. The cutting edge 41 can penetrate or extend into the through hole 11 and pierce the document to complete the punching action, used to cut the document to form a hole. The push rod 5 is fixed to the mounting frame 2 and extends into the inner cavity of the punching sleeve 4, slidingly engaging with it. After punching, the push rod 5 pushes the waste material out of the inner cavity to prevent blockage. The clamping component 6 is mounted on the base 1 to clamp the document, prevent it from shifting and ensure accurate punching. The lower surface of the base 1 is provided with a support leg 12 to ensure the stability of the document punching device during operation.

[0030] In actual use, the document to be punched is first placed on the base 1 at the position corresponding to the punching sleeve 4. The document is clamped and fixed by the clamping component 6 to prevent displacement during the punching process. At this time, the support feet 12 on the lower surface of the base 1 ensure that the entire device is placed stably. Then, the drive component 3 is started, which drives the punching sleeve 4, which is slidably connected to the mounting frame 2, to move downward. The cutting edge 41 at the lower end of the punching sleeve 4 passes through the through hole 11 on the base 1 and pierces the document, completing the punching action of cutting and forming a hole. After the punching is completed, the drive component 3 drives the punching sleeve 4 to return to its original position. During this process, the push rod 5, which is fixed on the mounting frame 2 and extends into the inner cavity of the punching sleeve 4, slides relative to the punching sleeve 4, pushing out the waste material remaining in the inner cavity of the punching sleeve 4 to avoid blockage. This completes one punching process for a document.

[0031] In this embodiment, the mounting bracket 2 includes a support arm 21, a mounting base 22, and a linear bearing 23. The support arm 21 is connected to the base 1, and this connection prevents the device from tilting or vibrating. The mounting base 22 is connected to the support arm 21 and serves as a fixed platform for the linear bearing 23 and the drive assembly 3, ensuring the coaxiality of the linear bearing 23 and the perforated sleeve 4, as well as the effective transmission of the thrust of the drive assembly 3. The linear bearing 23 is fixedly connected to the mounting base 22, and the perforated sleeve 4 passes through and is slidably connected to the linear bearing 23. The linear bearing 23 provides vertical guidance for the perforated sleeve 4, thereby improving the positional accuracy of the perforated hole.

[0032] In actual use, the punching device is initially in standby mode, with the punching sleeve 4 located inside the linear bearing 23, its upper end connected to the drive assembly 3, and its lower end suspended above the document. The mounting base 22 is fixed to the support arm 21, providing precise positioning for the linear bearing 23 and ensuring coaxiality with the punching sleeve 4. When the drive assembly 3 is activated, its output end pushes the punching sleeve 4 vertically down along the linear bearing 23, piercing the document and completing the punching. After punching, the drive assembly 3 drives the punching sleeve 4 smoothly back along the linear bearing 23, resetting it to its initial position, ready for the next punching operation.

[0033] In this embodiment, the drive assembly 3 includes a drive arm 31, a tension spring 32, and a transmission arm 33. The drive arm 31 is a slender rod and is rotatably connected to the mounting base 22. The tension spring 32 is an elastic reset element, with one end connected to the mounting base 22 and the other end connected to the drive arm 31, providing a reset force under tension. When the drive arm 31 swings down, the tension spring 32 is stretched, and it quickly resets when there is no external force on the drive arm 31. The transmission arm 33 is an L-shaped rod, with one end rotatably connected to the drive arm 31 and the other end rotatably connected to the upper end of the perforated sleeve 4.

[0034] In actual use, a downward external force is applied to the drive arm 31, causing the drive arm 31 to rotate downward around the connection point with the mounting base 22. At the same time, the tension spring 32 is stretched, and the drive arm 31 drives the punched sleeve 4 to move downward through the L-shaped transmission arm 33 rotatably connected to it. After punching is completed, the external force on the drive arm 31 is removed, and under the action of the return tension of the tension spring 32, the drive arm 31 quickly returns to its original position, and drives the punched sleeve 4 to return to its original position through the transmission arm 33.

[0035] In this embodiment, a mounting block 51 is provided at the lower end of the push rod 5, and its side wall is machined into a cylindrical shape that matches the inner wall of the punched sleeve 4. The side wall of the mounting block 51 can fit tightly against the inner wall of the punched sleeve 4 to form a sliding fit relationship, ensuring that the mounting block 51 can slide stably in its inner cavity when the punched sleeve 4 moves up and down, while effectively removing the waste generated by punching.

[0036] In actual use, during the operation of the multi-functional ticket punching device, the top rod 5 and its lower mounting block 51 work in conjunction with the punching sleeve 4 to ensure reliable removal of waste material. The top rod 5 is fixed to the mounting base 22, and its lower mounting block 51 is located in the inner cavity of the punching sleeve 4, with its side wall fitting against the inner wall of the punching sleeve 4. When the drive assembly 3 drives the punching sleeve 4 to move downward along the linear bearing 23, the mounting block 51 remains stationary relative to the punching sleeve 4, and the sliding fit between its side wall and the inner wall maintains the sealing of the inner cavity, preventing waste material from getting stuck. After punching is completed, the punching sleeve 4 returns upward, and the fitting side wall of the mounting block 51 pushes the ticket waste material in the inner cavity downward, completing the waste material removal and preparing for the next punching.

[0037] In this embodiment, the clamping assembly 6 includes a screw 61, a connecting frame 62, two guide shafts 63, a plate 65, and a fixing part 64. The screw 61 is a rod-shaped member with external threads, threadedly connected to the connecting frame 62 and rotatably connected to the plate 65. The plate 65 has a through hole for mounting the screw 61. When the screw 61 rotates, the connecting frame 62 can move linearly along the axial direction of the screw 61. The two guide shafts 63 are slender cylindrical members, with their upper ends fixedly connected to the connecting frame 62. The fixed connection of the guide shafts 63 ensures that they can move synchronously with the connecting frame 62, together forming the moving part of the clamping assembly 6. The two guide shafts 63 pass through the plate 65 and are slidably connected to the plate 65. The sliding connection between the guide shafts 63 and the plate 65 can effectively constrain the movement trajectory of the connecting frame 62, preventing it from deflecting or rotating during movement. Each guide shaft 63 has a fixing part 64 at its lower end, and the fixing part 64 is fixedly connected to the lower end of the guide shaft 63. The fixing part 64 is used to directly contact the surface of the document and apply clamping force to fix the document.

[0038] In actual use, when the clamping assembly 6 is not working, the connecting frame 62 is in the initial position of the screw 61, the guide shaft 63 passes through the plate 65, and the fixing part 64 is suspended above the document but not in contact with it. During clamping, the screw 61 is manually driven to rotate in the first direction, and the threaded transmission causes the connecting frame 62 to move axially downward, driving the guide shaft 63 to move downward synchronously. The guide shaft 63 slides within the guide hole of the plate 65, maintaining vertical movement and preventing tilting; the fixing part 64 approaches and contacts the document. After drilling, the screw 61 is manually driven to rotate in the second direction, the connecting frame 62 and the guide shaft 63 move upward, the fixing part 64 leaves the document, releasing the clamping force and returning to the initial state for the next operation. The first and second directions are opposite.

[0039] In this embodiment, the base 1 is further provided with a limiting part 13 for limiting the document; the limiting part 13 includes two first limiting plates 131 and one second limiting plate 132. The distance between the first limiting plates 131 and the second limiting plates 132 is optimized according to common document sizes to accommodate the width of the document. The inner surfaces of the two first limiting plates 131 are flat and smooth, serving as limiting surfaces for the sides of the document to prevent the document from sliding in the horizontal direction. The second limiting plate 132 is located on the same side of the two first limiting plates 131 and is fixedly connected to the base 1. The inner surface of the second limiting plate 132 cooperates with the inner surfaces of the two first limiting plates 131 to form a three-sided enclosed document limiting space. Its length direction is perpendicular to the spacing direction of the first limiting plates 131, used to restrict the movement of the document in another direction. The height and position design of the second limiting plate 132 ensures that the document can be easily placed into the limiting space while preventing it from shifting during punching.

[0040] In actual use, the ticket is placed on the base 1 and the limiting part 13 includes two first limiting plates 131 and a second limiting plate 132, which limit the horizontal movement of the ticket. After the clamping component 6 presses the ticket, the punching sleeve 4 moves down to complete the punching.

[0041] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
