Description

Technical Field

[0001] This utility model relates to the field of corrugated paper technology, and in particular to a dust collection component for a corrugated cardboard production line. Background Technology

[0002] Corrugated board production refers to the process of processing paper into corrugated board through specific techniques. This type of board is an important material in the packaging industry and is widely used in commodity packaging, transportation, and warehousing. First, the base paper is the basic material for corrugated board production. It is made from wood pulp, bamboo pulp, and other plant fibers. The base paper needs to undergo basis weight, thickness, and width treatment to ensure that its dimensions and quality meet production requirements. Second, the base paper is passed through a corrugating machine to form a continuous corrugated shape. Corrugated board consists of three layers: face paper, corrugated paper, and liner paper. Among them, the corrugated paper is the key layer, providing the strength and cushioning performance of the board. This process is called corrugation forming. Corrugated board production is a complex process that requires precise process control and high-quality raw materials to ensure the performance and reliability of the final product.

[0003] A search revealed Chinese Patent Publication No. CN222288182U, which discloses a utility model relating to the field of corrugated cardboard production lines, specifically a dust-collecting duct assembly for such a production line. This utility model provides a dust-collecting duct assembly for a corrugated cardboard production line, comprising a duct body, a starting port for connecting to the dust-collecting area of ​​the production line, and a negative pressure suction pump connected to the ending port. A dust filter is detachably installed between the starting and ending ports of the duct body. An impactor and a drive device connected to the impactor are mounted on the duct body. The drive device drives the impactor to reciprocate against the dust filter, causing the filter to vibrate and dislodge impurities. This vacuum duct assembly can clean most of the impurities on the surface of the dust filter without disassembling it, making the filter pores less prone to clogging. Although it can clean the filter through vibration, it cannot adjust the distance between itself and the vacuuming location, resulting in reduced vacuuming efficiency and practicality. Furthermore, vibration cleaning is ineffective against larger and stickier dust and debris, leading to reduced cleaning effect and applicability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dust collection component for a corrugated cardboard production line, aiming to improve the problem that the dust collection component in the existing corrugated cardboard production line cannot adjust the distance to the dust-collecting position, resulting in reduced dust collection efficiency and decreased practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dust collection component for a corrugated cardboard production line, comprising a hollow bottom plate, a telescopic hose fixedly connected to the inner wall of the hollow bottom plate, a top plate fixedly connected to the top of the telescopic hose, sliding rods fixedly connected between adjacent parts of the top plate and the hollow bottom plate, hollow rods provided on the outer wall of the sliding rods, multiple second rotating shafts rotatably connected to the bottom of the top plate, multiple rotating rods rotatably connected to the outer wall of the second rotating shafts, a first rotating shaft rotatably connected to the bottom of the second rotating rods, a third rotating shaft rotatably connected to the outer wall of the first rotating shaft, a double-ended lead screw threadedly connected to the inner wall of the first rotating shaft, a gear fixedly connected to the outer wall of the double-ended lead screw, a rack slidably connected to the inner wall of the top plate, the outer wall of the rack meshing with the outer wall of the gear, a connecting rod fixedly connected to the top of the rack, a telescopic rod fixedly connected to the bottom of the connecting rod, and a cleaning structure communicating with the top of the inner wall of the telescopic hose, the cleaning structure being used to clean larger debris.

[0006] Through the above technical solution: During the operation of the corrugated cardboard production line, some large debris and various foreign objects are inevitably generated. The cleaning structure can ensure the smooth operation of the production line. It is responsible for intercepting and cleaning larger foreign objects that attempt to enter the telescopic hose, thereby ensuring that the dust collection component can operate normally. When the rack moves up and down, it drives the gear meshing with it to rotate. The rotation of the gear will further drive the rotation of the connecting rod, so that the first rotating shaft can move flexibly to the sides or to the middle. This movement mechanism simultaneously pulls the rotating rods two and three on both sides, so that they can rotate in a coordinated manner, thereby ensuring the smooth and efficient dust collection of the entire production line. The telescopic rod can push the connecting rod to move up and down, thereby driving the entire mechanism to operate.

[0007] As a further description of the above technical solution:

[0008] The cleaning structure includes a connecting pipe, the bottom end of which is connected to the top end of a telescopic hose. A micro motor is fixedly connected to the outer wall of the connecting pipe. A storage box is connected to the bottom of the connecting pipe. A rotating plate is rotatably connected to the top of the storage box. A stop block is fixedly connected to the top of the rotating plate. A hollow tube is rotatably connected to the bottom of the inner wall of the storage box. A rotating rod is slidably connected to the inner wall of the hollow tube. A spring is fixedly connected to the bottom end of the rotating rod. A filter plate is fixedly connected to the middle of the inner wall of the connecting pipe. A scraper is rotatably connected to the inner wall of the filter plate. A worm gear is fixedly connected to the right end of the scraper. A worm is fixedly connected to the output end of the micro motor. The outer wall of the worm meshes with the outer wall of the worm gear.

[0009] Through the above technical solution: the spring always provides a stable upward thrust to the rotating rod, ensuring that the rotating rod can quickly return to its original position after completing a specific action, maintaining the stable operation of the entire structure; the rotating plate can open and close the storage box; and the hollow structure inside the hollow tube provides guiding space for the movement of the rotating rod.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the telescopic hose is provided with a collar, and the inner wall of the collar is rotatably connected to a rotating block.

[0012] The above technical solution involves using a rotating block to open the collar to both sides for installation.

[0013] As a further description of the above technical solution:

[0014] A fixing block is fixedly connected to the rear side of the collar, and multiple screws are threadedly connected to the inner wall of the fixing block.

[0015] Through the above technical solution: Screw 3 is used to fix the fixing block.

[0016] As a further description of the above technical solution:

[0017] The right end of the connecting pipe is connected to an exhaust fan, and a support plate is provided on the outer wall of the connecting pipe. A fixing rod is fixedly connected to each of the four corners of the top surface of the support plate.

[0018] Through the above technical solution, the exhaust fan is used to provide power for the entire dust collection mechanism.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the fixing rod is provided with a positioning plate, and the middle part of the outer wall of the fixing rod is provided with a second mounting plate. The inner wall of the second mounting plate is threaded with a plurality of screws.

[0021] Through the above technical solution, screw one can adjust the position between mounting plate two and positioning plate.

[0022] As a further description of the above technical solution:

[0023] The top of the fixing rod is fixedly connected to a mounting plate, and the inner wall of the mounting plate is threaded with multiple screws.

[0024] Through the above technical solution, screw two can fix and install mounting plate one.

[0025] As a further description of the above technical solution:

[0026] The bottom end of the telescopic hose is connected to a dust collection hood, and the multiple rotating rods are all rotatably connected to the same horizontal height.

[0027] Through the above technical solution, the dust collection hood can expand the dust collection range.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by activating the telescopic rod, the connecting rod is driven, which in turn pulls the rack to move up and down. This, in turn, drives the lead screw to rotate through the gear, allowing the first rotating shaft on its outer wall to move. This causes the second and third rotating rods to rotate along the second and third rotating shafts, respectively, thereby pulling the top plate and the hollow bottom plate to move relative to each other. This, in turn, causes the telescopic hose to expand and contract, achieving the purpose of adjusting the suction height of the component, accelerating the suction efficiency, and improving practicality.

[0030] 2. In this utility model, a micro motor is started to drive the worm gear to rotate, which in turn drives the scraper to rotate through the worm wheel, scraping away the debris on the left side of the filter plate. As the scraper rotates, it squeezes the rotating plate to rotate, and at the same time, it squeezes the rotating rod to compress the spring and retract it into the hollow tube, thus squeezing the debris into the storage box. Then, the spring pushes the rotating rod to push the rotating plate to rotate and reset, achieving the purpose of scraping and self-cleaning the device, improving the cleaning effect and expanding the scope of application.

[0040] 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.

[0041] Please see the appendix Figure 1 - Appendix Figure 3This utility model provides an embodiment of a dust collection assembly for a corrugated cardboard production line, comprising a hollow bottom plate 1, a telescopic hose 3 fixedly connected to the inner wall of the hollow bottom plate 1, the hollow bottom plate 1 supporting the telescopic hose 3, a top plate 4 fixedly connected to the top of the telescopic hose 3 for dust collection, a sliding rod 10 fixedly connected between adjacent parts of the top plate 4 and the hollow bottom plate 1, a hollow rod 11 provided on the outer wall of the sliding rod 10, the top plate 4 cooperating with the hollow bottom plate 1 to limit the telescopic hose 3, a plurality of second rotating shafts 7 rotatably connected to the bottom of the top plate 4, a plurality of rotating rods 6 rotatably connected to the outer wall of the second rotating shafts 7, a first rotating shaft 5 rotatably connected to the bottom of the rotating rods 6, the second rotating shafts 7 providing a fulcrum for the rotation of the rotating rods 6, and the outer wall of the first rotating shaft 5... A rotating rod 12 is rotatably connected, and a third rotating shaft 13 is rotatably connected to the bottom of the rotating rod 12. The first rotating shaft 5 enables the rotating rod 6 and the rotating rod 12 to rotate. A double-ended screw 14 is threadedly connected to the inner wall of the first rotating shaft 5. A gear 16 is fixedly connected to the outer wall of the double-ended screw 14. A rack 15 is slidably connected to the inner wall of the top plate 4. The double-ended screw 14 can drive the first rotating shaft 5 to move by rotating. The outer wall of the rack 15 meshes with the outer wall of the gear 16. A connecting rod 8 is fixedly connected to the top of the rack 15. The rack 15 can drive the gear 16 to rotate by moving. A telescopic rod 9 is fixedly connected to the bottom of the connecting rod 8. A cleaning structure 2 is connected to the top of the inner wall of the telescopic hose 3. The cleaning structure 2 is used to clean larger debris. The telescopic rod 9 can pull the connecting rod 8 to move up and down.

[0042] Specifically, during the operation of the corrugated cardboard production line, some large debris and other impurities are inevitably generated. The cleaning structure 2 intercepts and cleans these larger impurities that enter the telescopic hose 3, ensuring the normal operation of the dust collection components and the efficient execution of subsequent dust collection work. When the rack 15 moves up and down, it can drive the gear 16 meshing with it to rotate, which in turn drives the connecting rod 8 to rotate, so that the first rotating shaft 5 can move to the sides or to the middle, simultaneously pulling the rotating rods 6 and 12 on both sides to rotate.

[0043] Please see the appendix Figure 4 - Appendix Figure 6The cleaning structure 2 includes a connecting pipe 201, the bottom end of which is connected to the top end of a telescopic hose 3. A micro motor 202 is fixedly connected to the outer wall of the connecting pipe 201. The connecting pipe 201 is used to transport the dust collected by the telescopic hose 3. A storage box 210 is connected to the bottom of the connecting pipe 201. A rotating plate 208 is rotatably connected to the top of the storage box 210. A stop block 207 is fixedly connected to the top of the rotating plate 208. The storage box 210 is used to store larger miscellaneous items. A hollow tube 209 is rotatably connected to the bottom of the inner wall of the storage box 210. A rotating rod 212 is slidably connected to the inner wall of the hollow tube 209. 209 can guide the rotating rod 212 to move within it. The bottom end of the rotating rod 212 is fixedly connected to a spring 211. The middle of the inner wall of the connecting pipe 201 is fixedly connected to a filter plate 204. The spring 211 is used to push the rotating rod 212 to reset. The inner wall of the filter plate 204 is rotatably connected to a scraper 203. The right end of the scraper 203 is fixedly connected to a worm gear 206. The filter plate 204 is used to filter larger impurities. The output end of the micro motor 202 is fixedly connected to a worm 205. The outer wall of the worm 205 meshes with the outer wall of the worm gear 206. The micro motor 202 is used to drive the worm 205 to rotate.

[0044] Specifically, the scraper 203 can rotate around the rotating shaft on the surface of the filter plate 204, promptly cleaning up the debris accumulated on the filter plate 204, ensuring that the filter plate 204 always maintains good filtration performance, and ensuring that the dust collection assembly continuously and efficiently cleans dust and debris in the corrugated cardboard production line. The spring 211 can use its own elastic potential energy to continuously provide an upward thrust to the rotating rod 212, so that it can quickly return to its original position after completing a specific action, ensuring the stable operation of the cleaning structure 2. The storage box 210 is specifically used to store larger debris separated from the suction airflow, and the hollow tube 209 ensures that the rotating rod 212 can remain inside it, preventing it from leaving the predetermined range of movement.

[0045] Please see the appendix Figure 5 - Appendix Figure 7 The outer wall of the telescopic hose 3 is provided with a collar 23, and the inner wall of the collar 23 is rotatably connected to a rotating block 18. The collar 23 is used to fix the telescopic hose 3 and the rest of the structure. The right end of the connecting pipe 201 is connected to an exhaust fan 20. The outer wall of the connecting pipe 201 is provided with a support plate 19. The exhaust fan 20 can provide negative pressure for the entire dust collection mechanism. The four corners of the top surface of the support plate 19 are fixedly connected with fixing rods 22. The rear side of the collar 23 is fixedly connected with a fixing block 29. The inner wall of the fixing block 29 is threaded with multiple screws 28. The screws 28 are used to fix the fixing block 29.

[0046] Specifically, the support plate 19 is fixedly attached to the outer wall of the connecting pipe 201, providing reliable support for the connecting pipe 201. The fixing rod 22 further enhances the stability of the entire vacuuming assembly structure, effectively preventing the connecting pipe 201 from shifting or shaking due to vibration or external force during vacuuming, thereby ensuring the continuous and efficient operation of vacuuming. The collar 23 can fix the fixing block 29 with the screw 28, thereby limiting its position and connecting the telescopic hose 3 to its top structure.

[0047] Please see the appendix Figure 2 - Appendix Figure 4 The bottom end of the telescopic hose 3 is connected to a dust collection hood 17. Multiple rotating rods 6 are rotatably connected to the same horizontal height. The dust collection hood 17 is used to expand the dust collection range. The top end of the fixed rod 22 is fixedly connected to a mounting plate 25. Multiple screws 26 are threadedly connected to the inner wall of the mounting plate 25. The mounting plate 25 is used to install the entire structure. A positioning plate 21 is provided on the outer wall of the fixed rod 22. A mounting plate 27 is provided in the middle of the outer wall of the fixed rod 22. Multiple screws 24 are threadedly connected to the inner wall of the mounting plate 27. The positioning plate 21, together with the mounting plate 27, can limit the entire structure.

[0048] Specifically, the dust collection hood 17 can greatly expand the dust collection range. With its wide opening, it can efficiently collect these debris into the dust collection system, effectively improving the working efficiency of the dust collection component and ensuring the cleanliness of the environment around the production line. When the entire dust collection component needs to be installed in a specific working position, the operator only needs to place the mounting plate 25 on the pre-selected mounting surface, then align the screw 26 with the threaded hole and use a tool to gradually screw it in.

[0049] Working principle: When it is necessary to adjust the length of the telescopic hose 3 and thus adjust the height of the entire device, the telescopic rod 9 is activated first to pull the connecting rod 8, which in turn pulls the rack 15 to move downward, thereby driving the gear 16 to rotate, which in turn drives the lead screw 14 to rotate, so that the first rotating shafts 5 on both sides can move to both sides, thereby allowing the second rotating rod 6 and the third rotating rod 12 to rotate along the second rotating shaft 7 and the third rotating shaft 13 respectively, driving the sliding rod 10 to slide inside the hollow rod 11, while the top plate 4 and the hollow bottom plate 1 pull the telescopic hose 3 to retract and extend.

[0050] When vacuuming, larger debris and dust inevitably enter the device and adhere to the outer wall of the filter plate 204 due to the negative pressure suction. At this time, the micro motor 202 is started to drive the worm gear 205 to rotate, which in turn drives the worm wheel 206 to rotate, so that the scraper 203 can be rotated to scrape the debris on the left side of the filter plate 204. When it rotates to near the lowest point, the squeezing block 207 squeezes the rotating plate 208 to rotate, so that the rotating rod 212 is squeezed into the hollow tube 209 at the same time, the spring 211 is rotated and compressed, thereby discharging the debris scraped by the rotating rod 212 into the storage box 210.

[0051] 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.
