Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, and in particular to a punching device for paper product manufacturing. Background Technology

[0002] Paper products refer to various products made from paper as the main raw material, such as tissues, toilet paper, tissue boxes, cardboard boxes, paper bags, books, etc. Paper products have the advantages of being lightweight, easy to process, and inexpensive, and are widely used in daily life and industrial production. Paper products also come in a variety of forms. The most common form is a whole sheet of flat paper, but many paper products require perforation, such as hang tags and paper bags. It can be said that the perforation process is to enable paper products to meet specific usage requirements or to make them more compatible and unified with other products.

[0003] When existing punching equipment for paper product manufacturing punches multiple holes in a straight line on paper products according to specific usage requirements, it cannot guarantee the accuracy of the hole position, which can easily lead to the position of multiple holes being offset and not on a straight line.

[0004] Existing patent (publication number: CN220218785U) discloses a punching device for paper product manufacturing, comprising: a base plate, a fixing block, a through hole, a punching section, a calibration section, and a fastening device. The fixing block is mounted on the base plate, the through hole is opened in front of the fixing block, the punching section is mounted on the fixing block and the base plate, the calibration section is connected to the side of the fixing block and mounted on the base plate, and the fastening device is mounted on the calibration section. This punching device for paper product manufacturing can continuously and quickly punch holes in paper products with high quality through the punching section. At the same time, with the cooperation of the calibration section, it can ensure the uniformity of positioning of different parts of the paper product during the punching process, thereby ensuring that the continuously punched holes in the paper product are on the same straight line, and thus ensuring the accuracy of the position between multiple consecutive holes. In addition, with the cooperation of the annular blade, it can prevent the paper product from breaking when punching excessively thin paper products.

[0005] To address the aforementioned issues, existing patents offer solutions, but they lack a structure for simultaneously punching multiple holes in paper products. This results in equipment that can only punch one hole at a time needing to perform repeated operations when facing the demands of large-scale paper product production, thus reducing production efficiency.

[0006] Therefore, a perforation device for paper product manufacturing is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A punching device for paper product manufacturing includes a workbench 1, a punching mechanism 2 fixedly connected to the rear side of the top of the workbench 1, and a fixing mechanism 3 fixedly connected to the inner side of the chamfered corner of the top of the workbench 1.

[0029] The punching mechanism 2 includes a support plate 201, a first motor 202, a connecting plate 203, several rotating wheels 204, a connecting belt 205, and a punching knife 206. The support plate is fixedly connected to the rear side of the top of the workbench 1. The first motor 202 is fixedly connected to the left side of the top of the support plate 201. The output end of the bottom of the first motor 202 passes through the support plate 201 and the connecting plate 203 respectively and is fixedly connected to the top of the left rotating wheel 204. The connecting plate 203 is fixedly connected to the top of the inner side of the support plate 201. Several rotating wheels 204 are rotatably connected to the bottom of the connecting plate 203. The connecting belt 205 is sleeved on the surface of several rotating wheels 204. The punching knife 206 is fixedly connected to the bottom of the rotating wheel 204.

[0030] In this embodiment: By setting the workbench 1 as the basic support platform for the entire device, the stable installation and operation of the drilling mechanism 2 and the fixing mechanism 3 are ensured. The support plate 201 provides a firm mounting position for components such as the first motor 202, the connecting plate 203, and the rotating wheel 204, ensuring that the drilling mechanism 2 will not shake or shift during operation, thus guaranteeing the accuracy and stability of drilling. The first motor 202, as a power source, provides a strong driving force for the rotation of the rotating wheel 204, ensuring that the drilling cutter 206 can perform drilling operations quickly and accurately. The connecting plate 203 is connected to the top inner side of the support plate 201, providing stable support and rotation for the rotating wheel 204, allowing the rotating wheel 204 to rotate smoothly. The 04 can rotate smoothly, thereby driving the punching knife 206 to perform punching operations. Several rotating wheels 204 are connected by a connecting belt 205 to achieve synchronous rotation. The design of multiple rotating wheels 204 can drive multiple punching knives 206 to perform punching at the same time, which greatly improves the punching efficiency and meets the needs of large-scale paper product production. The connecting belt 205 connects multiple rotating wheels 204 together to achieve synchronous rotation, ensuring that the punching depth and position of each punching knife 206 are consistent, improving the punching accuracy and quality. The punching knife 206 is fixed at the bottom of the rotating wheel 204 and performs punching operations under the drive of the rotating wheel 204. The blade can quickly and accurately punch holes in paper products, ensuring the efficiency and quality of punching.

[0031] Specifically, such as Figure 3 As shown, the fixing mechanism 3 includes a hydraulic telescopic rod 301, a limiting platform 302, several limiting holes 303, a limiting groove 304, a threaded rod 305, a second motor 306, two pressing plates 307, a tension spring 308, a slider 309, a magnet 310, and a limiting rod 311. The hydraulic telescopic rod 301 is fixedly connected to the inner side of the top chamfer of the workbench 1.

[0032] Specifically, such as Figure 3 As shown, the telescopic end of the top of the hydraulic telescopic rod 301 is fixedly connected to the chamfer at the bottom of the limiting platform 302. The limiting hole 303 is opened on the front side of the top of the limiting platform 302. The inner side of the limiting hole 303 is used in conjunction with the punching tool 206. The limiting grooves 304 are respectively opened on the front and rear sides of the top of the limiting platform 302. The threaded rod 305 is fixedly connected to the inner side of the rear limiting groove 304. The second motor 306 is fixedly connected to the front side of the right side of the limiting platform 302. The output end of the left side of the second motor 306 passes through the limiting platform 302 and is rotatably connected between the limiting platform 302 and the limiting platform 302. The right side of the threaded rod 305 is fixedly connected to the output end of the left side of the second motor 306.

[0033] Specifically, such as Figure 3As shown, tension springs 308 are fixedly connected to the front and rear sides of the left side of the limiting platform 302, respectively. The left pressure plate 307 is fixedly connected to the top of tension springs 308. The front slider 309 is threadedly connected to the surface of the threaded rod 305. The rear slider 309 is slidably connected to the surface of the limiting rod 311. Magnets 310 are fixedly connected to the top of the inner side of slider 309, respectively. The right pressure plate 307 is attracted to the top of magnet 310.

[0034] In this embodiment: by setting a hydraulic telescopic rod 301, the height of the limiting platform 302 can be adjusted according to the paper product of different thicknesses, ensuring that the paper product maintains a stable position during the punching process and avoiding inaccurate punching positions due to different paper thicknesses. The limiting platform 302 provides a flat support surface for the paper product, and the limiting holes 303 on it work in conjunction with the punching knife 206 to precisely control the punching position and ensure the accuracy of punching. Several limiting holes 303 working in conjunction with the punching knife 206 ensure the accuracy of the punching position, and also... To prevent the punch 206 from shifting during the punching process and improve punching quality, the limiting groove 304 provides an installation position for the threaded rod 305 and the limiting rod 311, while also restricting the movement direction of the slider 309. This ensures that the pressure plate 307 can accurately move to the required position and firmly fix the paper product. Driven by the second motor 306, the threaded rod 305 moves the slider 309, thereby adjusting the position of the right-side pressure plate 307 to accommodate paper products of different sizes, improving the versatility and adaptability of the equipment. The second motor 306... The rotation of the threaded rod 305 provides power to automatically move the right-side pressure plate 307, making operation convenient and quick, and improving production efficiency. The two pressure plates 307, through the cooperation of the tension spring 308 and the magnet 310, can firmly fix the paper products, preventing paper displacement or shaking during punching and ensuring punching accuracy. The tension spring 308 provides a certain elastic pressure to the left-side pressure plate 307, allowing it to fit tightly against the paper products, while also facilitating the placement and removal of the paper products. The slider 309 is located on the threaded rod 305. With the help of the limiting rod 311, it can accurately move to the required position, driving the right pressure plate 307 to fix the paper product, ensuring the stability and reliability of the fixation. The magnet 310 cooperates with the right pressure plate 307, and the pressure plate 307 can be quickly and firmly fixed on the slider 309 through magnetic attraction, which improves the convenience and efficiency of operation. The limiting rod 311 cooperates with the threaded rod 305 to restrict the movement direction of the slider 309, ensuring that the slider 309 can move smoothly and guaranteeing the movement accuracy and stability of the right pressure plate 307.

[0035] Specifically, such as Figure 4 As shown, a rotating shaft 4 is fixedly connected to the left side of the inner side of the front limiting groove 304, and the left side of the threaded rod 305 is rotatably connected to the surface of the rotating shaft 4.

[0036] Specifically, such as Figure 5 As shown, a protective pad 5 is fitted on the bottom of the pressure plate 307, and the surface of the protective pad 5 is engraved with anti-slip texture.

[0037] In this embodiment: By setting the rotating shaft 4, a stable rotational support is provided for the left side of the threaded rod 305, ensuring that the threaded rod 305 remains stable during rotation without shaking or deviation. This allows the slider 309, which is threadedly connected to the threaded rod 305, to move precisely, ensuring the accuracy of the position adjustment of the right pressure plate 307 and improving the fixing effect on the paper product. By setting the protective pad 5, the surface of the paper product is protected from being scratched or damaged by the pressure plate 307 during the fixing process. Especially for some paper products with high surface quality requirements, the protective pad 5 plays an important protective role. By setting the anti-slip texture, the friction between the protective pad 5 and the paper product is increased, making the paper product more stable after fixing and less likely to move during the punching process, thus ensuring the accuracy of the punching.

[0038] Specifically, such as Figure 5 As shown, the adsorption surface of magnet 310 is engraved with anti-slip texture, and an adsorption block 6 is fixedly connected to the bottom of the right pressure plate 307. The adsorption block 6 is bonded to magnet 310.

[0039] Specifically, such as Figure 3 As shown, handles 7 are fixedly connected to the top of both pressure plates 307, and the surface of the handles 7 is engraved with anti-slip texture.

[0040] In this embodiment: by setting anti-slip texture, the anti-slip texture on the surface enhances the friction between the right pressure plate 307 and the right pressure plate 307, ensuring that the right pressure plate 307 will not easily slip during the adsorption process, making the fixation more secure. By setting adsorption block 6 and bonding it with magnet 310, the stability of adsorption is increased on the one hand, and the right pressure plate 307 is easy to replace on the other hand, improving the maintainability of the equipment. By setting handle 7, it is convenient for operators to quickly lift the pressure plate 307 when placing and taking out paper products, improving the convenience of operation. By setting anti-slip texture, the friction between the hand and handle 7 is increased, preventing the hand from slipping during operation, making the operation safer and more reliable.

[0041] Working Principle: First, the user places the workbench 1 in a suitable working position. Then, when preparing to punch holes in the paper product, the user powers on and starts the first motor 202. The output of the first motor 202 drives the left rotating wheel 204 to rotate. Through the connecting belt 205, several rotating wheels 204 rotate synchronously, thereby driving the punching knife 206 to rotate. At the same time, the user places the paper product on the limiting platform 302 and adjusts the height of the hydraulic telescopic rod 301 according to the thickness of the paper product to ensure that the paper product is in the appropriate punching position. Afterward, the user powers on and starts the second motor 306. The second motor 306 drives the threaded rod 305 to rotate, causing the front slider 309 to move threadedly on the surface of the threaded rod 305, and the rear slider 309 to slide on the surface of the limiting rod 311, thereby causing the right pressing plate 307 to move closer to the left. When the paper product contacts the right pressing plate 307, the user uses the handle 7 to move the right pressing plate... Pulling 307 upwards separates the right pressure plate 307 from the slider 309. The user then places the paper product on top of the slider 309 and attaches the right pressure plate 307 to the magnet 310 on top of the slider 309, thus securing the paper product. Simultaneously, the user pulls the handle 7 on top of the left pressure plate 307, placing the left side of the paper product at the bottom of the left pressure plate 307. The user then releases the handle 7, and the left pressure plate 307 returns to its original position under the action of the tension spring 308, securing the paper product. In this way, the two pressure plates 307 firmly fix the paper product to the limiting platform 302. Afterwards, the rotating punch 206 engages with the limiting hole 303 on the limiting platform 302 to punch holes in the paper product. Finally, when punching paper products of different sizes is required, the second motor 306 can be restarted to adjust the position of the pressure plates 307 to accommodate the new paper product size requirements.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
