Description

Technical Field

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

[0002] In the paper processing industry, with the booming development of printing and packaging, papermaking, and light industry, the performance requirements for paper processing equipment are increasing. As a key piece of equipment for accurately cutting wide sheets of paper into narrow strips of different specifications, the efficient and stable operation of slitting machines is crucial for improving production efficiency and product quality.

[0003] However, existing technologies, such as Chinese Publication No. CN222907121U, describe a cutting and slitting machine for paper product processing. This machine includes a base with multiple support blocks (three) fixedly connected to the top. A motor (two) is fixedly connected to the outer wall of one side of each support block (three). A toothed column is fixedly connected to the output end of the motor (two). Multiple blades are slidably connected to the outer wall of the toothed column. Multiple sliders are slidably connected to the inner wall of each blade. A connecting block (one) is provided on the outer wall of each slider. Multiple fixing rings are provided on the outer wall of each blade. A connecting block (two) is fixedly connected to the top of each connecting block (one). A dust removal component is provided on one side of the outer casing to absorb dust and fine debris generated after paper cutting. In this invention, by adjusting the spacing between the blades, the cutting requirements for paper strips of different widths are met, improving the convenience and practicality of the product and enhancing the user experience.

[0004] However, during the use of this device, it was found that although a vacuum cleaner was installed to absorb the dust and fine debris generated after paper cutting, relying solely on the suction power of the vacuum cleaner may not completely remove the dust when faced with a large amount of dust. This is especially true on large-scale, high-intensity paper product processing production lines, where the cutting speed is fast, the paper consumption is large, and the amount of dust generated far exceeds the capacity of the vacuum cleaner. As a result, a large amount of dust remains flying in the workshop and cannot be effectively collected. In addition, when the drawers in the collection box are removed for cleaning, dust may be stirred up again, causing secondary pollution. Long-term exposure to this dusty environment can easily lead to occupational diseases such as respiratory diseases and pneumoconiosis among workers. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor dust collection effect and easy secondary dust re-entrainment in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a paper product cutting and slitting machine, comprising: a worktable; equally spaced cutting parts, disposed above the worktable, with adjustment components at both ends of the cutting parts; a dust removal component, disposed on the back of the equally spaced cutting parts; a dust removal auxiliary component, disposed on the left and right sides of the worktable; and a waste collection box, movably disposed in a cavity provided inside the worktable.

[0008] In a preferred embodiment, the dust removal assembly includes: a dust collection box, which is fixedly connected to the back of the equally spaced cut pieces by bolts; a first suction wheel, which is provided in multiple sets and connected to the air intake of the dust collection box; a collection box, which is connected to the left and right sides of the dust collection box and is connected to the dust collection box through a connecting pipe; and a second suction wheel, which is located at the bottom of the collection box.

[0009] The technical effect of adopting the above-mentioned further solution is that: the dust suction box is fixed to the back of the cutting part, multiple sets of first suction wheels suck up dust from the air intake, the collection box is connected to the dust suction box through the connecting pipe, and the second suction wheel at the bottom of the inner part assists in efficiently adsorbing paper scraps and dust generated during cutting. The dust is then collected and processed in the collection box to keep the processing environment clean.

[0010] In a preferred embodiment, the dust removal auxiliary component includes: a water tank, disposed on both sides of the workbench, with a water pump installed inside; and multiple sets of atomizing nozzles, which are connected to the water tank via corrugated connecting pipes.

[0011] The technical effect of adopting the above-mentioned further solution is as follows: water tanks are set on both sides of the workbench, each containing a water pump. Multiple sets of atomizing nozzles are connected to the water tanks through corrugated connecting pipes, which can atomize and spray water to effectively settle the dust generated during cutting. In conjunction with the dust removal components, the dust removal effect of the device is further improved, and the air quality of the processing environment is improved.

[0012] In a preferred embodiment, the dust removal assembly further includes: a filter element disposed inside the dust collection box; and filter cotton disposed inside the collection box; wherein the filter element comprises, from bottom to top, a pre-filter, a medium-efficiency filter, and a high-efficiency filter, and the filtration coefficients of the three elements increase sequentially.

[0013] The technical effect of adopting the above-mentioned further solution is that the dust collection box is equipped with a filter element and the collection box contains filter cotton, which can filter the inhaled dust in stages. The primary filter removes large particles, the medium-efficiency filter and the high-efficiency filter intercept fine dust, and the filter cotton further purifies the dust, thereby improving dust removal efficiency and air quality.

[0014] In a preferred embodiment, the adjustment assembly includes: two mounting arms disposed at the lower ends of the equally spaced cutting member; and a rotating shaft fixedly connected to the bottom of the equally spaced cutting member, with a first motor fixedly connected to one end; wherein the rotating shaft is rotatably disposed at the upper end of the mounting arms, allowing the equally spaced cutting member to rotate around the central axis of the rotating shaft, thereby changing the cutting angle.

[0015] The technical effect of adopting the above-mentioned further solution is that the cutting parts are supported by two mounting arms at equal intervals, and the bottom rotating shaft is driven by the first motor, which can rotate at the upper end of the mounting arm, thereby driving the cutting parts to rotate around the central axis, realizing flexible adjustment of the cutting angle, meeting different cutting needs, and improving the applicability and processing flexibility of the equipment.

[0016] In a preferred embodiment, the adjustment assembly further includes: mounting blocks, fixedly connected to the left and right sides of the worktable; a lead screw, rotatably disposed between a set of mounting blocks, one end of which is fixedly connected to a second motor; wherein the bottom of the mounting arm is connected to the lead screw.

[0018] In a preferred embodiment, a pad is laid on the workbench, and the pad has several through holes that communicate with the inner cavity of the workbench.

[0019] The technical effect of adopting the above-mentioned further solution is that during cutting, waste material can fall into the waste collection box inside the workbench through the drain hole, avoiding the accumulation of waste material on the workbench surface and affecting processing. At the same time, with the dust removal component, dust is discharged through the drain hole with the airflow, keeping the workbench surface clean and improving processing efficiency and environmental cleanliness.

[0020] In a preferred embodiment, an indicator needle is provided on the side of the equally spaced cut piece, and a scale is provided on one side of the indicator needle.

[0021] The technical effect of adopting the above-mentioned further solution is that: the side of the equally spaced cutting part is equipped with an indicator needle and a scale on one side, which can intuitively display the position adjustment amount of the cutting part, making it easier for operators to accurately control the cutting parameters, ensuring the accuracy of the cutting position, and improving the processing precision and operation convenience.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. This utility model forms a three-dimensional dust removal system through the cooperation of dust removal components and auxiliary dust removal components. The dust collection box is securely installed on the back of the equally spaced cutting parts with bolts. Multiple sets of first suction wheels are tightly connected to the air intake, which can quickly adsorb a large amount of dust at the moment of cutting. The sucked-in dust enters the collection box through the connecting pipe, and the second suction wheel at the bottom of the box further enhances the collection effect. At the same time, the filter elements in the dust collection box, consisting of a primary filter, a medium-efficiency filter, and a high-efficiency filter, and the filter cotton in the collection box, form a multi-stage filtration system to finely filter the dust layer by layer. In addition, the water pumps in the water tanks on both sides of the workbench deliver water to the atomizing nozzles through corrugated connecting pipes, spraying out a fine water mist, causing the suspended dust in the air to settle, assisting the dust removal components. Even in large-scale, high-intensity production operations, it can effectively prevent dust from flying, completely solve the problem of incomplete dust removal in existing equipment, and greatly improve the workshop working environment.

[0024] 2. This utility model effectively avoids the risk of secondary dust pollution. The collection box is connected to the dust extraction box via a connecting pipe. Dust is collected and filtered within the sealed pipe and box system, unlike the drawer-type design of existing equipment that easily leads to dust dispersion. Moreover, the dust removal components and auxiliary dust removal components operate continuously, continuously purifying the surrounding air while cleaning the waste collection box, further reducing dust dispersion. This design fundamentally eliminates secondary dust pollution, reduces the risk of workers suffering from respiratory diseases, pneumoconiosis, and other occupational diseases due to long-term exposure to dust, fully protects the health of workers, and meets the requirements of modern green production.

[0031] 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.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a cutting and slitting device for paper product processing, characterized in that it includes a workbench 1, equally spaced cutting parts 2, a dust removal component, a dust removal auxiliary component, and a waste collection box 14;

[0033] The workbench 1 serves as the basic load-bearing component, providing a stable working platform for the entire equipment;

[0034] The equally spaced cutting piece 2 is located above the worktable 1, and adjustment components are installed at the bottom of both ends of it. These adjustment components enable the equally spaced cutting piece 2 to be flexibly adjusted in terms of spatial position and angle to adapt to different cutting needs.

[0035] The dust removal component is fixed to the back of the equally spaced cutting parts 2, which can promptly remove dust such as paper scraps generated during the cutting process;

[0036] Dust removal auxiliary components are distributed on the left and right sides of the workbench 1, working together with the dust removal components to further improve the dust removal effect;

[0037] The waste collection box 14 is movably installed in the cavity inside the workbench 1 to collect the waste generated during cutting.

[0038] like Figure 1-4 As shown, the dust removal assembly consists of a dust suction box 3, multiple sets of first suction wheels 4, a collection box 5, a second suction wheel 7, filter elements, and filter cotton 8;

[0039] The dust extraction box 3 is securely fixed to the back of the equally spaced cutting parts 2 with bolts to ensure that it remains in a stable position during equipment operation;

[0040] Multiple sets of first suction wheels 4 are connected in an orderly manner at the air inlet of the dust collection box 3. By generating a strong suction, the dust generated during the cutting process is sucked into the dust collection box 3.

[0041] The collection box 5 is symmetrically connected to the left and right sides of the suction box 3, and is connected to the inside of the suction box 3 through the connecting pipe 6, so that the dust sucked into the suction box 3 can smoothly enter the collection box 5.

[0042] The second suction wheel 7 is installed at the bottom of the collection box 5 to further enhance the dust collection effect and prevent dust from overflowing into the collection box 5;

[0043] The filter elements are installed inside the dust collection box 3, and are arranged from bottom to top as a primary filter 9, a medium-efficiency filter 10, and a high-efficiency filter 11. The filtration coefficients of the three increase in sequence, forming a multi-stage filtration system to gradually and finely filter the inhaled dust.

[0044] The filter cotton 8 is placed inside the collection box 5 to further absorb residual dust.

[0045] like Figure 1-4 As shown, the dust removal auxiliary components include a water tank 15 and multiple sets of atomizing nozzles 17. Water tanks 15 are respectively provided on both sides of the workbench 1. A water pump is installed inside the water tank 15, which can extract and transport the water in the water tank 15.

[0046] Multiple sets of atomizing nozzles 17 are connected to the water tank 15 through corrugated connecting pipes 16. The water pump delivers water to the corrugated connecting pipes 16, and then sprays out fine water mist through the atomizing nozzles 17. The water mist combines with dust in the air, causing it to settle, thereby helping the dust removal components to better purify the working environment.

[0047] like Figure 1-4 As shown, the adjustment assembly consists of two mounting arms 18, a rotating shaft 19, a first motor 20, a mounting block 23, a lead screw 24, and a second motor 25.

[0048] Two mounting arms 18 are respectively positioned at the lower ends of the equally spaced cutting parts 2 to provide support for the equally spaced cutting parts 2;

[0049] The rotating shaft 19 is fixedly connected to the bottom of the equally spaced cutting piece 2, and one end is fixedly connected to the first motor 20. The rotating shaft 19 can rotate at the upper end of the mounting arm 18. Under the drive of the first motor 20, it can drive the equally spaced cutting piece 2 to rotate around the central axis of the rotating shaft 19, so as to achieve precise adjustment of the cutting angle.

[0050] Mounting blocks 23 are fixed on the left and right sides of the workbench 1, providing a mounting base for the lead screw 24. The lead screw 24 is rotatably mounted between a set of mounting blocks 23, with one end fixedly connected to the second motor 25. The bottom of the mounting arm 18 is connected to the lead screw 24. When the second motor 25 drives the lead screw 24 to rotate, it can drive the mounting arm 18 to move along the lead screw 24, thereby realizing the horizontal position adjustment of the equally spaced cutting parts 2.

[0051] like Figure 1-4 As shown, a pad 12 is laid on the surface of the workbench 1, and several drainage holes 13 are opened through the pad 12. The drainage holes 13 are connected to the inner cavity of the workbench 1, and the waste and dust generated by cutting can fall into the waste collection box 14 in the inner cavity of the workbench 1 through the drainage holes 13.

[0052] The side of the equally spaced cutting part 2 is provided with an indicator needle 22, and a scale 21 is provided on one side of the indicator needle 22, so that the operator can intuitively understand and adjust the position of the equally spaced cutting part 2.

[0053] Working principle: This equipment is a paper product cutting and slitting machine. When in use, the paper product to be processed is first placed stably on the pad 12 of the worktable 1. The position and angle of the equally spaced cutting parts 2 are adjusted by adjusting the components. The mounting blocks 23, lead screw 24 and second motor 25 installed on both sides of the worktable 1 drive the lead screw 24 to rotate, so that the mounting arm 18 moves the equally spaced cutting parts 2 to the appropriate position in the horizontal direction. Then, the first motor 20 is started to drive the rotating shaft 19 to rotate, so that the equally spaced cutting parts 2 rotate around its axis. At the same time, the required cutting angle is accurately set by referring to the indicator needle 22 and the scale 21.

[0054] Once ready, start the equipment. The evenly spaced cutting element 2 begins to operate, cutting the paper products into strips. During this process, the dust removal components work simultaneously. The back of the dust collection box 3 is fixed to the evenly spaced cutting element 2 with bolts. Multiple sets of first suction wheels 4 generate suction at the air intake of the dust collection box 3, sucking in paper scraps and other dust generated during cutting. The dust enters the collection box 5 connected to both sides of the dust collection box 3 through the connecting pipe 6. The second suction wheel 7 at the bottom of the collection box 5 further enhances the collection effect. The dust collection box 3, composed of a primary filter, a medium-efficiency filter, and a high-efficiency filter, and the filter cotton 8 in the collection box 5, perform multi-stage filtration and purification of the dust.

[0055] Meanwhile, the dust removal auxiliary components come into play. The water pumps in the water tanks 15 on both sides of the workbench 1 start, delivering water through the corrugated connecting pipe 16 to multiple sets of atomizing nozzles 17. The atomizing nozzles 17 spray out a fine water mist, causing the dust in the air to settle and assisting in dust removal. The waste and dust generated during cutting fall into the waste collection box 14 inside the workbench 1 through the drain holes 13 on the pad 12.

[0056] After the cutting work is completed, turn off the equipment, remove the waste collection box 14 to clean the waste, and check and clean the filter elements and filter cotton 8 of the dust removal component to prepare for the next use.

[0057] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
