[0001] The invention relates to the technical field of dust recovery, in particular to a dust recovery device for corrugated paperboard production. Background Art

[0002] In the production of corrugated cardboard, the processes of base paper cutting, corrugated forming, glue coating, drying process and equipment wear will cause paper fiber breakage, impurities to fall off and component debris to be generated, thus forming dust. If the dust is not properly handled, it will escape into the air, polluting the environment, endangering the health of operators and increasing the risk of respiratory diseases and pneumoconiosis. Moreover, dust can easily enter the precision parts of the equipment, accelerate wear and shorten the service life of the equipment. It will also adhere to the corrugated cardboard, affecting the quality of subsequent processing and reducing the product qualification rate. Therefore, professional dust recovery equipment is needed to handle the dust.

[0003] In the dust treatment process, dust is mainly intercepted by filter elements. However, as the use time of the filter elements increases, its filtering performance will gradually decay. At this time, the filter elements need to be replaced in time. However, the current filter element replacement method has many disadvantages.

[0007] As a further improvement of the above scheme, the sealing assembly also includes a movable seat slidably connected to the inside of the support seat, a spring is symmetrically fixedly connected between the movable seat and the support seat, a pressure roller is evenly rotated and connected to the bottom of the movable seat, a connecting sleeve is fixedly connected to the inside of the movable seat, and a fixed sleeve that penetrates the support seat is fixedly connected to the inside of the fan, and the fixed sleeve is slidably connected to the inside of the connecting sleeve.

[0008] As a further improvement of the above scheme, the inside of the equipment base is fixedly connected to a fixed seat, the top of the fixed seat is fixedly connected to a diverter plate, the fixed seat and the diverter plate are located inside the belt drive assembly, and the circulation pipe passes through the equipment base and is connected to the inside of the fixed seat.

[0009] As a further improvement of the above scheme, the driving mechanism includes a movable rod slidably connected to the circulation pipe, the circulation pipe is internally rotatably connected to a driving shaft, the outer side of the driving shaft is fixedly connected to a gear, the movable rod is internally fixedly connected to a rack, the rack and the gear are meshed with each other, the movable rod penetrates to the inner side of the docking tube and fits with the slider, the interior of the mounting seat is symmetrically rotatably connected to a one-way shaft, a universal joint is fixedly connected between the one-way shaft and the driving shaft, the outer side of the one-way shaft is fixedly connected to a worm, the outer side of the mounting sleeve is fixedly connected to a worm wheel, and the worm and the worm wheel are meshed with each other.

At this time, under the action of wind pressure, the driving mechanism is triggered. The driving mechanism drives the installation shaft in the mounting seat to rotate. When the filter is completely moved into the docking pipe, the installation shaft drives the mounting seat to rotate synchronously, realizing the convenient replacement of the entire filter mechanism, effectively solving the problem of difficult replacement and affecting work efficiency in the traditional method.

[0014] 2. The support seat uses the elastic force of the spring to press the corrugated paper onto the belt drive assembly. The connecting sleeve cooperates with the fixed sleeve to discharge the dust in the space between the movable seat and the belt drive assembly. During the dust discharge process, the airflow in the circulation pipe is acted on by the diverter plate, causing the belt drive assembly to vibrate, making it easier for the dust to detach from the corrugated paper, effectively improving the dust removal efficiency.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 10 As shown, the present invention provides an embodiment: A dust recovery device for corrugated cardboard production, comprising a device base 1, a belt transmission assembly 2 is arranged on the inner side of the device base 1, a sealing assembly 3 is arranged on the top of the device base 1, the sealing assembly 3 comprises a support seat 31 fixedly connected to the top of the device base 1, a fan 4 is fixedly connected to the top of the support seat 31, a fixed pipe 8 is fixedly connected to the outside of the fan 4, a circulation pipe 5 is fixedly connected to the outside of the support seat 31 through a support 7, a dust removal assembly 6 is arranged between the support 7 and the fixed pipe 8, and the dust removal assembly 6 comprises a rotating seat 61, a mounting mechanism 62, a filtering mechanism 63 and a driving mechanism 64; The mounting mechanism 62 includes a mounting seat 621 fixedly connected to the circulation pipe 5, a mounting sleeve 622 is rotatably connected inside the mounting seat 621, a mounting shaft 623 is rotatably connected inside the mounting sleeve 622, the rotating seat 61 is fixedly connected to the mounting seat 621, and a torsion spring 625 is fixedly connected between the mounting sleeve 622 and the mounting shaft 623; The filter mechanism 63 includes a butt joint pipe 631 slidably connected to the inside of the rotating seat 61, a movable pipe 632 is slidably connected to the inside of the butt joint pipe 631, a filter seat 634 is fixedly connected to the inside of the movable pipe 632, a filter screen 633 is fixedly connected between the filter seat 634 and the movable pipe 632, and a slider 635 is fixedly connected to the top of the movable pipe 632; The driving mechanism 64 is disposed inside the circulation pipe 5 and is used for transmitting kinetic energy from the filtering mechanism 63 to the driving mechanism 64 .

[0020] In practical application, the embodiment of the present invention is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the fan 4 is started, so that the fan 4 drives the dust in the support seat 31 to enter the dust removal assembly 6 through the fixed pipe 8 and is filtered through the filter screen 633 and the filter seat 634; like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when the dust accumulates to a certain extent inside the filter 633, the filtering effect of the filter 633 and the filter seat 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 toward the fixed tube 8, and start the driving mechanism 64 through the slider 635; like Figure 6 , Fig. 9 and Fig.10 As shown, the worm 648 is driven to rotate by the driving mechanism 64, and the worm 648 drives the installation sleeve 622 to rotate through the meshing connection with the worm wheel 649, thereby realizing the torsional deformation of the torsion spring 625 between the installation sleeve 622 and the installation shaft 623. When the movable tube 632 moves to the specified position, the driving mechanism 64 drives the movable block 624 to release the limitation on the position of the installation shaft 623. At this time, when the installation sleeve 622 is fixed in position, the elastic reset of the torsion spring 625 drives the installation shaft 623 to drive the rotating seat 61 to rotate, thereby realizing the overall rotation of the filtering mechanism 63 inside the rotating seat 61, so as to facilitate the timely replacement of the filtering mechanism 63, while ensuring the filtering effect and improving the replacement efficiency.

[0021] like Figures 2 to 4 As shown, the sealing assembly 3 also includes a movable seat 32 slidably connected to the inside of the support seat 31, a spring 33 is symmetrically fixedly connected between the movable seat 32 and the support seat 31, a pressure roller 38 is evenly rotated and connected to the bottom of the movable seat 32, a connecting sleeve 36 is fixedly connected to the inside of the movable seat 32, a fixed sleeve 37 penetrating the support seat 31 is fixedly connected to the inside of the fan 4, the fixed sleeve 37 is slidably connected to the inside of the connecting sleeve 36, a fixed seat 34 is fixedly connected to the inside of 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, and the circulation pipe 5 penetrates the equipment base 1 and is connected to the inside of the fixed seat 34.

[0022] When the embodiment of the present invention is actually used, the movable seat 32 installed by the support seat 31 through the spring 33 can press the corrugated paper on the top of the belt drive assembly 2 through the pressure roller 38, and the belt drive assembly 2 can more stably drive the corrugated paper to move at the bottom of the movable seat 32 under the support of the diverter plate 35, and form a relatively closed space to ensure the discharge effect of dust under negative pressure. In addition, the purified air can act on the belt drive assembly 2 through the fixed seat 34 and the diverter plate 35, driving the belt drive assembly 2 to vibrate in the equipment base 1, so as to shake out the dust, further improve the dust recovery effect, and avoid residue.

[0023] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the driving mechanism 64 includes a movable rod 646 slidably connected to the circulation pipe 5, the circulation pipe 5 is internally rotatably connected to a driving shaft 644, the outer side of the driving shaft 644 is fixedly connected to a gear 643, the movable rod 646 is internally fixedly connected to a rack 647, the rack 647 and the gear 643 are meshed with each other, the movable rod 646 penetrates to the inner side of the docking pipe 631 and fits with the slider 635, the mounting seat 621 is internally symmetrically rotatably connected to a one-way shaft 641, a universal joint 642 is fixedly connected between the one-way shaft 641 and the driving shaft 644, a worm 648 is fixedly connected to the outer side of the one-way shaft 641, a worm wheel 649 is fixedly connected to the outer side of the mounting sleeve 622, the worm 648 and the worm wheel 649 are meshed with each other, a torsion spring 2 645 is symmetrically fixedly connected between the driving shaft 644 and the circulation pipe 5, and the bottom of the gear 643 penetrates to the inner side of the circulation pipe 5.

[0024] When the embodiment of the present invention is applied in practice, the movable tube 632 pushes the movable rod 646 to move through the slider 635 during the movement. Since the movable rod 646 is meshed 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 driving shaft 644 to rotate synchronously to achieve the torsional deformation of the torsion spring 645. At the same time, the one-way shaft 641 can be driven 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 installation sleeve 622 to rotate through the worm gear 649, so as to facilitate the deformation and energy storage of the torsion spring 1 625 inside the installation sleeve 622. Since the structural characteristics of the one-way shaft 641 can only achieve one-way rotation, the one-way shaft 641 cannot drive the worm 648 to flip, so that the installation sleeve 622 cannot flip, so that when the installation shaft 623 contacts the limit, the rotating seat 61 can be driven to rotate under the action of the elastic potential energy of the torsion spring 1 625.

[0025] like Figure 6 , Figure 7 and Fig.10As shown, the inside of the mounting seat 621 is slidably connected with a movable block 624, the outer side of the torsion spring 625 is evenly provided with limiting grooves, the top of the movable block 624 is slidably connected to the inside of the limiting groove, the bottom of the movable block 624 is provided with a guide groove, and the movable rod 646 is slidably connected in the guide groove.

[0026] In actual application of the embodiment of the present invention, when the movable tube 632 is completely moved into the docking 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 installation shaft 623 .

[0027] like Figure 8 As shown, a slide groove is provided at the top of the butt joint pipe 631, and the slider 635 is slidably connected in the slide groove.

[0028] In actual application, the embodiment of the present invention ensures the stability of the sliding of the movable tube 632 through the sliding groove, avoids deviation, and can accurately push the movable rod 646.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
