[0002] A document binding and punching device is a specialized device used to punch holes in various documents (such as financial ledgers, invoices, and documents) for subsequent binding. In finance departments, it is used to punch and bind financial documents such as ledgers, invoices, and receipts. This device ensures the neatness and standardization of documents, facilitating subsequent archiving and retrieval.

[0003] A typical document binding and punching device consists of a base, a punching mechanism, and a collection mechanism. When in use, the base serves as a stable support platform, bearing and precisely positioning other components to ensure overall structural stability. The punching mechanism uses a pneumatic rod to drive the perforating roller to precisely press down and punch the required holes in the documents on the placement plate, efficiently completing the punching task. The collection mechanism keeps the work area clean and orderly.

[0004] However, some existing devices rely solely on simple clamping structures to secure documents. This design often fails to provide a stable and uniform fixing force when dealing with documents of varying thicknesses, materials, and sizes, causing misalignment during the punching process and resulting in inaccurate punching positions, which affects the subsequent binding effect. Therefore, a document binding punching device is proposed to solve the above problems. Utility Model Content

The pneumatic rod 22 is designed to provide punching capacity. A perforating roller 23 is fixedly connected to the output end of the pneumatic rod 22, which is designed to provide punching capacity. The punching force of the pneumatic rod 22 drives the perforating roller 23 to... The stamping process enables punching, and the outside of the perforating roller 23 is located on the top of the placement plate 5. The top of the base 1 is rotatably connected to the rotating disk 3, which is designed to provide support while allowing rotation, so that the ledger can be rotated at different angles after being placed on the top of the rotating disk 3. The top of the rotating disk 3 is provided with a fixing mechanism 4, and the top of the base 1 is fixedly connected to one side of the placement plate 5, which is designed to provide support, so that one side of the ledger can be supported. The top two sides of the base 1 are provided with collection mechanisms 6.

[0035] The fixing mechanism 4 includes two sliding blocks 41, designed to provide sliding capability. The two sliding blocks 41 are slidably connected to the top of the rotating disk 3. The top of the rotating disk 3 has a sliding groove 42, designed to provide sliding space, allowing the sliding blocks 41 to slide within the groove 42. The bottoms of the two sliding blocks 41 are slidably connected to the inside of the sliding groove 42. Support blocks 43 are fixedly connected to the tops of the two sliding blocks 41, designed to provide support capability. Simultaneously, the movement of the sliding blocks 41 can drive the support blocks 43 to move. An extrusion assembly 44 is fixedly connected inside the two support blocks 43. The extrusion assembly 44 includes two guide posts 441, designed to... To provide guidance, two guide posts 441 are fixedly connected to the inner top walls of two support blocks 43 on their outer sides. Compression springs 442 are respectively fitted onto the outer sides of the two guide posts 441. Their design provides compression force, allowing the compression springs 442 to be compressed or stretched, generating elastic force to apply pressure to the ledger. Simultaneously, the guide posts 441 provide guidance for the compression springs 442, preventing deviation. The top side of the pressing plate 45 is fixedly connected to the bottom of the guide posts 441. The pressing assembly 44 is fixedly connected to the outside of the pressing plate 45, which is designed to fix the ledger. The compression springs 442 compress the pressing plate 45, causing it to press against the ledger. To prevent displacement during drilling and placement, a support block 46 is fixedly connected to the outer adjacent side of the two sliding blocks 41. This design provides good support. A fixing component 47 is slidably connected to the top of the rotating disk 3. The fixing component 47 includes two sliders 471, designed to provide sliding capability. The outer sides of the two sliders 471 are slidably connected to the top of the rotating disk 3. Two grooves 472 are formed on the top of the two rotating disks 3, designed to provide sliding space, allowing the sliders 471 to slide within the grooves 472. The outer sides of the two sliders 471 are slidably connected to the inside of the grooves 472. A support frame 4 is fixedly connected to the top of the two sliders 471. 73, its design can provide support capacity, and the slider 471 can drive the slide groove 472 to slide when sliding. The outer side of the support frame 473 is rotatably connected to the rotating column 474, which can provide support capacity. The outer side of the rotating column 474 is fixedly connected to the cam 475, which can be placed horizontally and rotated through the support of the rotating column 474. At the same time, the cam 475 rotates non-centered, so that when the more convex side rotates, it can be fixed to the top of the pressing plate 45, which can enhance the fixation of the ledger. At the same time, through the support of the support block 46, it provides good bottom support for the ledger, and the outer side of the pressing plate 45 is vertically located on the top of the support block 46.

[0036] Reference Figure 4 and Figure 5The collection mechanism 6 includes a collection box 61, designed to provide collection capacity. The collection box 61 is externally slidably connected to the inside of the rotating disk 3. The rotating disk 3 has arc-shaped grooves 66 on both sides of its top. The collection box 61 is slidably connected inside one of the arc-shaped grooves 66, allowing for the collection of debris during punching. The outside of the collection box 61 is slidably connected to the outside of the arc-shaped groove 66. Two adjusting rods 62 are fixedly connected to the top of the collection box 61, designed to provide telescopic capability. When the perforating roller 23 presses, the adjusting rods 62 retract. Return springs 63 are fixedly connected inside the two adjusting rods 62, designed to provide... The return spring 63 provides a reset capability, allowing the top side of the adjusting rod 62 to extend after the perforating roller 23 is pressed down. The top of the two adjusting rods 62 is fixedly connected to the support plate 64, which is designed to provide support for the area to be perforated. Then, the perforating roller 23 is pressed down, causing the support plate 64 to move down. At the same time, the placement plate 5 is supported on the other side of the perforated area of ​​the ledger, preventing one side from pressing down as well. The inside of the arc-shaped groove 66 is fixedly connected to multiple placement slots 65, which are designed to provide placement space for perforating rollers 23 of different sizes.

[0037] Working Principle: When using this voucher binding and punching device, the ledger is first placed on the fixing mechanism 4 at the top of the rotating disk 3. At this time, the two sliding blocks 41 in the fixing mechanism 4 slide in the sliding groove 42, which can accommodate ledgers of different sizes, driving the top support block 43 to move, thereby causing the pressing assembly 44 to operate. In the pressing assembly 44, the guide post 441 provides guidance for the pressing spring 442. The pressing spring 442 is compressed and generates elastic force, pushing the pressing plate 45 to move downward. The pressing plate 45 applies pressure to the ledger, fixing it above the support block 46. At the same time, the slider 471 in the fixing assembly 47 slides in the sliding groove 472, driving the support frame 473 to move. The rotating post 474 on one side of the support frame 473 supports the cam 475. The non-central rotation characteristic of the cam 475 allows its protruding part to press against the top of the pressing plate 45 when rotating, further enhancing the fixation of the ledger and ensuring that the ledger will not shift during punching and placement. Next, rotate the turntable 3 to adjust the ledger to the appropriate punching angle as needed. At this time, the punching mechanism 2 starts to work. The air rod 22 remains vertical under the support of the support plate 21. Its punching capacity drives the perforating roller 23 at the output end to perform a punching action. The perforating roller 23 punches holes in the ledger placed on the top of the placement plate 5 to complete the punching work.

[0038] During punching, the collection box 61 is located in the arc-shaped groove 66 on one side of the rotating disk 3, ready to collect the debris generated during punching. When the punching mechanism 2 starts working, the pneumatic rod 22 drives the perforating roller 23 to press down, punching holes in the ledger placed on the placement plate 5. During the punching process, the support plate 64 supports the punching area of ​​the ledger under the support of the adjusting rod 62, while the placement plate 5 supports the other side of the punching area of ​​the ledger to prevent one side of the ledger from pressing down during punching. When the perforating roller 23 presses down, the adjusting rod 62 retracts, and the return spring 63 is compressed. After punching is completed, the pneumatic rod 22 drives the perforating roller 23 to move upward, and the elastic force of the return spring 63 causes the adjusting rod 62 to extend, and the support plate 64 returns to its original position. At this time, the collection box 61 slides in the arc-shaped groove 66 to collect the debris generated during the punching process. Multiple placement slots 65 outside the arc-shaped groove 66 can be placed according to the perforated roller 23 of different sizes so that the perforated roller 23 can be replaced when needed.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
