Description

Technical Field

[0001] This invention relates to the field of dust recovery technology, and in particular to a dust recovery device for corrugated cardboard production. Background Technology

[0002] In corrugated cardboard production, processes such as paper cutting, corrugation, glue coating, drying, and equipment wear can cause paper fiber breakage, impurity shedding, and component debris, which in turn generate dust. If this dust is not properly handled, it will escape into the air, pollute the environment, harm the health of operators, and increase the risk of respiratory diseases and pneumoconiosis. Moreover, dust can easily enter precision parts of equipment, accelerating wear and shortening the equipment's lifespan. It can also adhere to the corrugated cardboard, affecting the quality of subsequent processing and reducing the product qualification rate. Therefore, it is necessary to use professional dust recovery equipment to treat the dust.

[0003] In dust treatment processes, dust is mainly intercepted by filter cartridges. However, as the filter cartridges are used for a longer period of time, their filtration performance will gradually decline. At this time, the filter cartridges need to be replaced in time. However, the current filter cartridge replacement methods have many drawbacks. Not only is the operation process cumbersome, but in order to ensure the safety of the replacement process, the dust recovery operation also needs to be interrupted, which will reduce the overall recovery efficiency.

[0004] Therefore, there is a need for a dust recovery device for corrugated cardboard production, which aims to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a dust recovery device for corrugated cardboard production, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A dust recovery device for corrugated cardboard production includes a base, a belt drive assembly on the inner side of the base, a sealing assembly on the top of the base, a support fixedly connected to the top of the base, a fan fixedly connected to the top of the support, a fixed pipe fixedly connected to the outer side of the fan, a circulation pipe fixedly connected to the outer side of the support through a bracket, and a dust removal assembly between the bracket and the fixed pipe. The dust removal assembly includes a rotating base, a mounting mechanism, a filtering mechanism, and a driving mechanism.

[0008] The installation mechanism includes a mounting base fixedly connected to the circulation pipe, an installation sleeve rotatably connected inside the mounting base, an installation shaft rotatably connected inside the installation sleeve, a rotating seat fixedly connected to the mounting base, and a torsion spring fixedly connected between the installation sleeve and the installation shaft.

[0009] The filtration mechanism includes a connecting pipe slidably connected inside the rotating seat, a movable pipe slidably connected inside the connecting pipe, a filter seat fixedly connected inside the movable pipe, a filter screen fixedly connected between the filter seat and the movable pipe, and a slider fixedly connected to the top of the movable pipe.

[0010] The drive mechanism is located inside the circulation pipe and is used for the transfer of kinetic energy from the filtration mechanism to the drive mechanism.

[0011] As a further improvement to the above solution, the sealing assembly also includes a movable seat that is slidably connected inside the support base. A spring is symmetrically fixedly connected between the movable seat and the support base. A pressure roller is rotatably connected to the bottom of the movable seat. A connecting sleeve is fixedly connected inside the movable seat. A fixed sleeve that penetrates the support base is fixedly connected inside the fan. The fixed sleeve is slidably connected inside the connecting sleeve.

[0012] As a further improvement to the above solution, a fixed seat is fixedly connected inside the equipment base, and a diverter plate is fixedly connected to the top of the fixed seat. The fixed seat and the diverter plate are located inside the belt drive assembly, and the circulation pipe passes through the equipment base and communicates with the inside of the fixed seat.

[0013] As a further improvement to the above solution, the driving mechanism includes a movable rod slidably connected inside the circulation tube, a drive shaft rotatably connected inside the circulation tube, a gear fixedly connected to the outside of the drive shaft, a rack fixedly connected inside the movable rod, the rack and the gear meshing with each other, the movable rod penetrating to the inside of the connecting tube and fitting against the slider, a one-way shaft symmetrically rotatably connected inside the mounting base, a universal joint fixedly connected between the one-way shaft and the drive shaft, a worm fixedly connected to the outside of the one-way shaft, and a worm wheel fixedly connected to the outside of the mounting sleeve, the worm and the worm wheel meshing with each other.

[0014] As a further improvement to the above solution, the mounting base has a movable block slidably connected inside, the outer side of the torsion spring is evenly provided with a limiting groove, the top of the movable block is slidably connected to the inside of the limiting groove, the bottom of the movable block is provided with a guide groove, and the movable rod is slidably connected to the guide groove.

[0015] As a further improvement to the above solution, a groove is provided on the top of the connecting pipe, and the slider is slidably connected in the groove.

[0016] As a further improvement to the above solution, a torsion spring is symmetrically fixedly connected between the drive shaft and the circulation tube, and the bottom of the gear extends through to the inside of the circulation tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. After the fan starts, its suction force draws dust from inside the support base through the fixed pipe into the filter mechanism. Dust gradually accumulates on the filter screen; when the accumulation reaches a certain level, the filtration efficiency decreases. At this point, under the action of air pressure, the drive mechanism is triggered. The drive mechanism rotates the mounting shaft inside the mounting base. When the filter screen is completely moved into the connecting pipe, the mounting shaft drives the mounting base to rotate synchronously, enabling convenient replacement of the entire filter mechanism and effectively solving the problems of difficult replacement and reduced work efficiency in traditional methods.

[0019] 2. The support base uses the elastic force of a spring to press the corrugated paper onto the belt drive assembly. The connecting sleeve cooperates with the fixed sleeve to allow dust to be discharged from the space between the movable base and the belt drive assembly. During the dust discharge process, the airflow in the circulation pipe, through the action of the diverter plate, causes the belt drive assembly to vibrate, making it easier for dust to detach from the corrugated paper and effectively improving dust removal efficiency.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0033] Please see Figures 1 to 10 As shown, the present invention provides an embodiment:

[0034] A dust recovery device for corrugated cardboard production includes a base 1, a belt drive assembly 2 on the inner side of the base 1, a sealing assembly 3 on the top of the base 1, a support 31 fixedly connected to the top of the base 1, a fan 4 fixedly connected to the top of the support 31, a fixed pipe 8 fixedly connected to the outer side of the fan 4, a circulation pipe 5 fixedly connected to the outer side of the support 31 via a support 7, and a dust removal assembly 6 between the support 7 and the fixed pipe 8. The dust removal assembly 6 includes a rotating seat 61, an installation mechanism 62, a filtering mechanism 63, and a driving mechanism 64.

[0035] The mounting mechanism 62 includes a mounting base 621 fixedly connected to the circulation pipe 5, a mounting sleeve 622 rotatably connected inside the mounting base 621, a mounting shaft 623 rotatably connected inside the mounting sleeve 622, a rotating seat 61 fixedly connected to the mounting base 621, and a torsion spring 625 fixedly connected between the mounting sleeve 622 and the mounting shaft 623.

[0036] The filter mechanism 63 includes a connecting tube 631 slidably connected inside the rotating seat 61, a movable tube 632 slidably connected inside the connecting tube 631, a filter seat 634 fixedly connected inside the movable tube 632, a filter screen 633 fixedly connected between the filter seat 634 and the movable tube 632, and a slider 635 fixedly connected to the top of the movable tube 632.

[0037] The drive mechanism 64 is located inside the circulation pipe 5 and is used for the kinetic energy transfer from the filter mechanism 63 to the drive mechanism 64.

[0038] In practical applications, the embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the fan 4 is started, which causes the dust in the support base 31 to enter the dust removal component 6 through the fixed pipe 8 and be filtered by the filter screen 633 and the filter base 634.

[0039] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when dust accumulates to a certain extent inside the filter screen 633, the filtration effect of the filter screen 633 and the filter base 634 is reduced. At this time, the partial pressure of the dust driven by the fan 4 will push the movable tube 632 to move towards the fixed tube 8, and start the drive mechanism 64 through the slider 635.

[0040] like Figure 6 , Figure 9 and Figure 10 As shown, the drive mechanism 64 drives the worm gear 648 to rotate. The worm gear 648, through its meshing connection with the worm wheel 649, drives the mounting sleeve 622 to rotate, thereby achieving the torsional deformation of the torsion spring 625 between the mounting sleeve 622 and the mounting shaft 623. When the movable tube 632 moves to the designated position, the drive mechanism 64 drives the movable block 624 to release the restriction on the position of the mounting shaft 623. At this time, with the mounting sleeve 622 in a fixed position, the elastic reset of the torsion spring 625 drives the mounting shaft 623 to drive the rotating seat 61 to rotate, thereby achieving the overall rotation of the filter mechanism 63 inside the rotating seat 61. This facilitates timely replacement of the filter mechanism 63, ensuring the filtration effect while improving replacement efficiency.

[0041] like Figures 2 to 4As shown, the sealing assembly 3 also includes a movable seat 32 that is slidably connected inside the support base 31. A spring 33 is symmetrically fixedly connected between the movable seat 32 and the support base 31. A pressure roller 38 is uniformly rotatably connected to the bottom of the movable seat 32. A connecting sleeve 36 is fixedly connected inside the movable seat 32. A fixed sleeve 37 that penetrates the support base 31 is fixedly connected inside the fan 4. The fixed sleeve 37 is slidably connected inside the connecting sleeve 36. A fixed seat 34 is fixedly connected inside the equipment base 1. A diverter plate 35 is fixedly connected to the top of the fixed seat 34. The fixed seat 34 and the diverter plate 35 are located inside the belt drive assembly 2. The circulation pipe 5 penetrates the equipment base 1 and communicates with the inside of the fixed seat 34.

[0042] In practical application, the movable seat 32, mounted on the support base 31 via the spring 33, can press the corrugated paper onto the top of the belt drive assembly 2 via the pressure roller 38. Furthermore, the belt drive assembly 2, supported by the diverter plate 35, can more stably drive the corrugated paper to move at the bottom of the movable seat 32, forming a relatively enclosed space to ensure effective dust discharge under negative pressure. Additionally, the fixed seat 34 and the diverter plate 35 can act on the belt drive assembly 2, causing it to vibrate within the equipment base 1, thus shaking out dust and further improving dust recovery efficiency and preventing residue.

[0043] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the drive mechanism 64 includes a movable rod 646 slidably connected inside the circulation tube 5. A drive shaft 644 is rotatably connected inside the circulation tube 5. A gear 643 is fixedly connected to the outside of the drive shaft 644. A rack 647 is fixedly connected inside the movable rod 646. The rack 647 and the gear 643 mesh with each other. The movable rod 646 passes through to the inside of the connecting tube 631 and fits against the slider 635. A one-way shaft 641 is symmetrically rotatably connected inside the mounting base 621. A universal joint 642 is fixedly connected between the one-way shaft 641 and the drive shaft 644. A worm 648 is fixedly connected to the outside of the one-way shaft 641. A worm wheel 649 is fixedly connected to the outside of the mounting sleeve 622. The worm 648 and the worm wheel 649 mesh with each other. A torsion spring 645 is symmetrically fixedly connected between the drive shaft 644 and the circulation tube 5. The bottom of the gear 643 passes through to the inside of the circulation tube 5.

[0044] In practical application, during the movement of the movable tube 632, the movable rod 646 is moved by the slider 635. Since the movable rod 646 meshes with the gear 643 through the rack 647, the movable rod 646 will drive the gear 643 to rotate during the movement. The gear 643 drives the drive shaft 644 to rotate synchronously, realizing the torsion deformation of the second torsion spring 645. At the same time, it can drive the one-way shaft 641 to rotate through the universal joint 642. The rotating one-way shaft 641 can drive the worm 648 to rotate. The worm 648 drives the mounting sleeve 622 to rotate through the worm wheel 649, so that the torsion spring 625 inside the mounting sleeve 622 can deform and store energy. Due to the structural characteristics of the one-way shaft 641, it can only achieve unidirectional rotation. Therefore, the one-way shaft 641 cannot drive the worm 648 to flip, so that the mounting sleeve 622 cannot be flipped. When the mounting shaft 623 contacts the limit, it can drive the rotating seat 61 to rotate under the action of the elastic potential energy of the first torsion spring 625.

[0045] like Figure 6 , Figure 7 and Figure 10 As shown, a movable block 624 is slidably connected inside the mounting base 621. Limiting grooves are evenly opened on the outer side of the torsion spring 625. The top of the movable block 624 is slidably connected to the inside of the limiting groove. A guide groove is opened at the bottom of the movable block 624. The movable rod 646 is slidably connected to the guide groove.

[0046] In practical application, when the movable tube 632 is fully moved into the connecting tube 631, the movable rod 646 pushes the movable block 624 out of the limiting groove through the guide groove, thereby releasing the rotation restriction on the mounting shaft 623.

[0047] like Figure 8 As shown, a groove is provided on the top of the connecting pipe 631, and the slider 635 is slidably connected in the groove.

[0048] In practical applications, the sliding groove of this invention ensures the stability of the sliding of the movable tube 632, preventing deviation, while accurately pushing the movable rod 646.
