Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a hole punch for paper office supplies, comprising:

[0024] The device consists of a support plate 1 and a top frame 3. The top frame 3 is fixedly connected to the upper surface of the support plate 1. Multiple columns 2 are fixedly connected to the lower side of the support plate 1. Each column 2 has a pad 21 fixedly connected to its lower surface. The lower surface of each pad 21 has anti-slip textures to improve the stability of the device. A scale strip 12 is fixedly connected to the upper surface of the support plate 1. A punching assembly and a pressing assembly are installed on the top frame 3. A collection assembly is also included. The collection assembly includes a storage slot on the support plate 1, and a cleaning box 4 is slidably connected inside the storage slot. The upper surface of the support plate 1 has an installation groove 5, the inner wall of the installation groove 5 has a cleaning port 6, the side wall of the installation groove 5 has a sliding groove 7, multiple moving blocks 8 slide in the installation groove 5, each of the multiple moving blocks 8 has a through hole 9, the side wall of each of the multiple moving blocks 8 is fixedly connected to a connecting plate 10, the multiple connecting plates 10 slide in the sliding groove 7, each of the multiple connecting plates 10 has a threaded bolt 11, the multiple bolts 11 are all set on the support plate 1, and the side wall of each of the multiple connecting plates 10 is fixedly connected to a positioning rod 13;

[0025] The punching assembly includes a first cylinder 14 fixedly installed on the side wall of the top frame 3. A moving groove is opened in the inner wall of the top frame 3, and an installation block is slidably connected in the moving groove. A second cylinder 15 is fixedly installed on the lower end face of the installation block. The telescopic end of the first cylinder 14 slides through the top frame 3 and is fixedly connected to the installation block. A punching device 16 is fixedly installed on the telescopic end of the second cylinder 15. The punching device 16 is existing technology. Its working principle is mainly to transmit the high-frequency vibration driven by the electromagnet to the punching head through the transmission system, so that the punching head generates high-frequency vibration, thereby quickly punching holes in the paper. It will not be described in detail here. The punching device 16 is located above the cleaning port 6. A moving port is opened in the inner wall of the moving groove. A moving rod is fixedly connected to the side wall of the installation block. The moving rod slides in the moving port. An infrared sensor 17 is fixedly installed on the lower end face of the moving rod. The infrared sensor 17 is existing technology. It is a device that can detect the infrared radiation emitted by an object. It uses the characteristics of infrared radiation to sense the position of the object. It will not be described in detail here.

[0026] The pressing assembly includes a fixed plate fixedly connected to the side wall of the top frame 3. A third cylinder 18 is fixedly installed on the upper surface of the fixed plate. The telescopic end of the third cylinder 18 slides through the fixed plate and is fixedly connected to a pressing plate 19. A connecting groove is opened on the support plate 1. A storage box 20 is slidably connected in the connecting groove. The storage box 20 can store the moving block 8 to prevent the moving block 8 from being lost. A handle is fixedly connected to both the cleaning box 4 and the storage box 20. The handle makes it easy for the user to pull the cleaning box 4 and the storage box 20, improving the portability of the device. Anti-slip pads are provided on both side walls of the cleaning box 4 and the storage groove. The anti-slip pads increase the friction between the cleaning box 4 and the storage groove, and between the storage box 20 and the connecting groove, preventing the cleaning box 4 and the storage box 20 from sliding automatically.

[0027] It is worth noting that the entire device controls the first cylinder 14, the second cylinder 15, the third cylinder 18, the drilling device 16, and the infrared sensor 17 through the main control system. Since the first cylinder 14, the second cylinder 15, the third cylinder 18, the drilling device 16, and the infrared sensor 17 matched by the main control system are common equipment and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.

[0028] The detailed working process of this utility model is as follows:

[0029] First, the user places the device in the designated position, then removes the movable blocks 8 from the storage box 20. Next, based on the number of holes to be punched in the paper office supplies, the corresponding number of movable blocks 8 are inserted into the mounting slot 5. The spacing between adjacent movable blocks 8 is then determined using the positioning rod 13 and the scale bar 12. The bolt 11 is then tightened so that one end of the bolt 11 abuts against the support plate 1, thus fixing the movable blocks 8 in place. This allows the device to adjust the number and spacing of the movable blocks 8 according to the punching requirements, improving its practicality. The user then places the paper office supplies against the edge of the scale bar 12, ensuring they are parallel, and adjusts their position using the scale bar 12. Then, the third cylinder 18 begins operation, driving... The pressing plate 19 descends, pressing and fixing the paper office supplies to prevent them from moving. Then, the first cylinder 14 starts working, and its telescopic end drives the mounting block to move. When the infrared sensor 17 detects the position of the positioning rod 13, the first cylinder 14 stops working. Then, the second cylinder 15 starts working, driving the punching device 16 to descend and perform punching work. The degree of automation is high. This process is repeated to complete the punching work in sequence. The moving block 8 can support the punching point, improving the stability of punching. Paper scraps will fall into the cleaning box 4 through the through hole 9, avoiding the scraps from affecting the punching, improving the accuracy and quality of punching, and also making it easier to collect scraps for user cleaning.
