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 with waste collection function. Background Technology

[0002] In the production and processing of cardboard, punching is a common process. In the early days, cardboard punching was mainly done manually using simple tools such as needles and awls. This method was inefficient, difficult to guarantee accuracy, and labor-intensive. With the development of industrial technology, mechanical punching methods have emerged, such as punching machines and drilling machines.

[0003] In the existing technology, cardboard box punching and chip collection devices generally do not have a feeding device, which requires manual feeding, thereby increasing labor costs and reducing work efficiency. Moreover, the cardboard box punching and chip collection devices on the market cannot recycle the chips after punching, thus reducing their practicality.

[0004] To address the aforementioned issues, an existing patent (publication number: CN219485885U) proposes a punching device for paper product manufacturing with waste collection function. A bracket is fixedly connected to the lower side of the front end of the base, a transmission mechanism is installed on the upper side of the front end of the base, and a punching mechanism is installed at the upper end of the base. This cardboard box punching and waste collection device can effectively process cardboard boxes, reduce waste generation, thereby improving environmental protection, reducing enterprise costs, and achieving waste utilization. The collected cardboard scraps can be recycled and reused in the production of other products, thus realizing the resource utilization of waste. The device is equipped with a suction fan and a waste collection box, which can quickly and effectively collect cardboard fragments, thereby maintaining a clean and hygienic working environment. The rotation of a motor drives a transmission rod, which in turn drives a conveyor belt, which in turn drives a rotating rod on a fixed plate, thus achieving the feeding function and facilitating the feeding and processing of cardboard boxes.

[0005] To address the aforementioned issues, existing patents offer solutions. However, before processing paper products with special requirements, it is necessary to punch holes in cardboard with high rigidity using a special mold. This results in the generation of large round fragments and smaller paper dust. These fragments are difficult to collect and adhere to the cardboard and mold surfaces due to the upward inertia of the punching mold, affecting subsequent punching. Even with effective cleaning and collection, the paper dust and round fragments are mixed together and difficult to separate, making it challenging to recycle and reuse the round fragments.

[0006] To address this, a punching device for paper product manufacturing with waste collection function is proposed. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a collection mechanism, can achieve the effect of separating larger round wood chips and smaller wood scraps when collecting waste materials from perforated cardboard. At the same time, the waste box is easy to remove, and it is convenient to classify, recycle and clean after collection. The waste box is installed through the base plate, and the hydraulic rod lifts the support base plate to make the filter box fit with the receiving trough. The debris generated by the punching operation and cleaning enters the filter box through the receiving trough. When the waste box fits with the bottom of the receiving trough, the electrostatic rod is located between the filter box and the waste box and close to the rubber plate. When collecting waste, the electrostatic rod attracts wood scraps through the screen and adsorbs itself. Then, the motor drives the gear and gear ring to make the electrostatic rod rotate around and adsorb. During adsorption, the electrostatic rod rotates. Since the electrostatic rod is close to the rubber plate but not in contact with it, the electrostatic rod adsorbs wood scraps and rotates and rotates, causing the scraps to stick to the rubber plate.

[0019] 2. This application, by setting up a cleaning mechanism, can prevent small wood chips from remaining on the surface of the cardboard and punching die during the punching operation, thus avoiding affecting subsequent operations. After cleaning, the chips on the surface of the punching table can be gradually guided and collected into the waste box. The cardboard is placed on the perforated shelf supported by the spring inside the telescopic support for punching. When the punching is pressed down, the spring is squeezed to lower the perforated shelf below the height of the baffle. The blower blows the wood chips away from the surface of the cardboard and punching die, causing them to fall into the bottom collection trough or be blocked by the baffles on the surface of the punching table on both sides. After punching is completed, the continuous air outlets intermittently blow air to guide the chips on the table to the middle of the punching table and then guide them to the collection trough through the sliding guide groove.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A punching device for paper product manufacturing with waste collection function includes a punching table 1, characterized in that: a cleaning mechanism 5 is movably connected to the top of the punching table 1, and a collection mechanism 6 is movably connected to the bottom of the punching table 1.

[0030] The collection mechanism 6 includes a base plate 61, a hydraulic rod 62, a waste box 63, a filter box 64, a rubber plate 65, an electrostatic rod 66, a motor 67, a gear ring 68, a gear 69, and a motor 610. The base plate 61 is slidably connected to the bottom of the punching platform 1. The hydraulic rod 62 is located on the bottom of the inner side of the punching platform 1 and is fixedly connected to the bottom of the base plate 61. The waste box 63 is slidably connected to the inner side of the base plate 61. The filter box 64 and the rubber plate 65 are fixedly connected to the inner side of the waste box 63. The gear ring 68 is rotatably connected to the bottom of the punching platform 1. The motor 67 is fixedly connected to the bottom of the gear ring 68. The electrostatic rod 66 is fixedly connected to the output end of the motor 67. The motor 610 is fixedly connected to the inner side of the punching platform 1. The gear 69 is fixedly connected to the output end of the motor 610 and is meshed with the right side of the gear ring 68.

[0031] In this embodiment: After the waste box 63 is installed via the base plate 61, the hydraulic rod 62 lifts and supports the base plate, so that the filter box 64 is in contact with the receiving trough 58. During punching and cleaning, the debris enters the filter box 64 through the receiving trough 58. The outside of the filter box 64 is a screen. When the waste box 63 is in contact with the bottom of the receiving trough 58, the electrostatic rod 66 is located between the filter box 64 and the waste box 63 and is close to the rubber plate 65. When collecting waste, the electrostatic rod 66 attracts wood debris to pass through the screen and adsorbs itself. Then, the motor 610 drives the gear 69 and the gear ring 68 to make the electrostatic rod 66 rotate and adsorb. During adsorption, the electrostatic rod 66 rotates. Because the electrostatic rod 66 is close to the rubber plate 65 but not in contact with it, after the electrostatic rod 66 adsorbs the wood debris, its rotation and rotation cause the debris to stick to the rubber plate 65 and be collected.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a row of air inlets 51 is fixedly connected to the top of the punching platform 1, a baffle 52 is fixedly connected to the top of the row of air inlets 51, and a fan 53 is provided on the top of the punching platform 1.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a support leg 54 is fixedly connected to the top of the punching platform 1, a telescopic support column 55 is fixedly connected to the top of the support leg 54, a compression spring 56 is fixedly connected to the inner side of the telescopic support column 55, a hollow shelf 57 is fixedly connected to the top of the telescopic support column 55, and a baffle 52 is provided on the outer side of the hollow shelf 57.

[0034] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a receiving groove 58 is provided on the top of the punching table 1, and the receiving groove 58 is located on the top of the filter box 64. A sliding guide groove 59 is provided on the top of the punching table 1, and the sliding guide groove 59 is located on the outside of the receiving groove 58.

[0035] In this embodiment: a rigid cardboard is punched on a perforated shelf 57 supported by a spring 56 inside a telescopic support column 55. When the punching is pressed down, the spring 56 is squeezed to lower the perforated shelf 57 below the height of the baffle 52. The blower 53 blows the wood chips away from the rigid cardboard and the surface of the punching mold 4, causing them to fall into the bottom receiving trough 58 or the surface of the punching table 1 on both sides and be blocked by the baffle 52. After the punching is completed, the continuous air outlets 51 intermittently blow air to guide the chips on the table to the middle of the punching table 1 and guide them to the receiving trough 58 through the sliding guide groove 59.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, a two-way threaded rod 7 is threadedly connected to the right side of the outer side of the hollow shelf 57, and a hollow clamping plate 8 is threadedly connected to the outer side of the two-way threaded rod 7. The hollow clamping plate 8 is set on the top of the hollow shelf 57.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, an electronic telescopic rod 9 is fixedly connected to the inner side of both the hollow clamping plate 8 and the hollow storage plate 57, and an extension clamping plate 10 is fixedly connected to the outer side of the electronic telescopic rod 9.

[0038] In this embodiment: the distance between the two side extension plates 10 can be adjusted by the electronic telescopic rod 9 to accommodate rigid cardboard of different lengths and widths, and the cardboard is clamped by tightening the bidirectional threaded rod 7.

[0039] Specifically, such as Figure 5 As shown, positioning magnetic blocks 11 are fixedly connected to the left side of the waste box 63 and the left side of the inner side of the base plate 61.

[0040] Specifically, such as Figure 5 As shown, elastic compression columns 12 are fixedly connected to the left and right sides of the inner side of the waste box 63, and a handle 13 is fixedly connected to the top of the elastic compression column 12.

[0041] In this embodiment: elastic extrusion columns 12 are fixedly connected to the left and right sides of the inner side of the waste box 63. A handle 13 is fixedly connected to the top of the elastic extrusion column 12. A support base 2 is fixedly connected to the bottom of the punching table 1. A gantry punching frame 3 is fixedly connected to the outer side of the punching table 1. A punching mold 4 is fixedly connected to the bottom of the gantry punching frame 3. The punching mold 4 is set on the top of the punching table 1.

[0042] Working principle: Before punching, the handles 13 on both sides of the waste box 63, which is free of impurities, are pressed down to compress the elastic compression column 12, causing the handles 13 to retract. The waste box 63 can then slide inward along the base plate 61. When it reaches the innermost side of the base plate 61, the positioning magnetic block 11 on the outer side of the waste box 63 will attract and position itself with the positioning magnetic block 11 on the inner side of the base plate 61. Then, the hydraulic rod 62 raises the height of the base plate 61, causing the filter box 64 inside the waste box 63 to fit into the collection trough 58. This allows round wood chips and wood scraps to be collected during punching operations and subsequent cleaning of the punching table 1. The trough 58 directly enters the filter box 64, the outer side of which is a screen. When the waste box 63 is in contact with the bottom of the receiving trough 58, the electrostatic rod 66 at the bottom of the toothed ring 68 on the inner side of the punching platform 1 will be positioned between the filter box 64 and the waste box 63, and close to the inner rubber plate 65 of the waste box 63. During the waste collection process, the electrostatic rod 66 will attract the wood chips inside the filter box 64, causing them to pass through the filter screen and be adsorbed onto the electrostatic rod 66. The motor 610 will drive the gear 69 to rotate, causing the electrostatic rod 66 to rotate in a circular motion within the waste box 63 for adsorption. During the adsorption process, the electrostatic rod 66... The electrostatic rod 66 rotates via the motor 67. Because the electrostatic rod 66 is close to the adhesive plate 65 but not in contact with it, after the electrostatic rod 66 attracts wood chips, it rotates and moves in a circular motion. The wood chips on its surface will stick to the adhesive plate 65, thus achieving adhesion and collection. Before waste collection, the spacing of the extension clamp 10 can be adjusted by the electronic telescopic rod 9 to accommodate rigid cardboard of different lengths and widths. Furthermore, by placing the rigid cardboard on the perforated shelf 57 supported by the inner compression spring 56 of the telescopic support 55 and punching holes, pressing down to punch holes will squeeze the inner compression spring 56 of the telescopic support 55, causing the perforated shelf 57 to descend. The height is below the baffle 52. Then, the blower 53 blows the punching area so that the wood chips can be separated from the surface of the hard cardboard and the punching mold 4 and fall into the bottom collection trough 58 or fall into the surface of the punching table 1 on both sides and be blocked by the baffle 52. After punching, the continuous blower 51 intermittently blows air to guide the table chips to the middle position of the punching table 1 and guides them into the collection trough 58 through the sliding guide groove 59. Finally, after the punching waste is collected, the hydraulic rod 62 is lowered, the waste box 63 is pulled out, the handle 13 pops out, the round chips are inside the filter box 64, and the wood chips are stuck on the glue plate 65 to complete the classification and collection.

[0043] 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.
