Description

Technical Field

[0001] The present invention relates to the field of dust removal equipment, in particular to an air suction dust removal equipment for a corrugated cardboard production line and a use method thereof. Background Art

[0002] A corrugated cardboard production line is the core equipment for corrugated cardboard manufacturing. Its operating principle is to first heat the corrugated paper and pass it through corrugating rollers to form the flutes (flutes are categorized as B, C, and E, distinguished by flute height). The prepared flutes and lining paper are then bonded together using glue (primarily composed of corn starch or tapioca starch). An automatic sheet-straightening device is incorporated into this process to correct the cardboard's position on the line, ensuring a good bond between the two, improving product quality. Next, the top and bottom layers of kraft paper are glued together. The resulting corrugated cardboard is then heated and dried on curved hot plates (a boiler return system is included to save energy). The resulting corrugated cardboard is then cut by two slitter machines (two slitter machines are used to allow for seamless product changes without slowing down production). The slitting process is then cross-cut and palletized.

[0003] Dust is released into the workshop when corn / tapioca starch is used to make glue, and a small amount of paper scraps are released into the workshop during the corrugated cardboard cutting process. If the dust in the corrugated paper production workshop is not properly removed, it will not only affect the health of the workers, but also the quality of the produced cardboard.

[0004] Current workshop dust removal equipment usually includes bag-type dust collectors, which work in the following way: the air in the workshop is pumped to the bag-type dust collector through a fan, the air is discharged after being filtered through the dust collector bags, and the dust in the air remains in the dust collector bags. Although the current common bag-type dust collectors can filter and remove dust in the workshop air, as dust adheres to the dust collector bags, the dust removal effect of the dust collector bags will be reduced. If the dust collector bags are not regularly inspected and replaced, the filtering effect of the dust in the workshop air will be reduced. Therefore, the existing bag-type dust collectors need to regularly inspect the bags during use, which causes great inconvenience during use. Summary of the Invention

DETAILED DESCRIPTION

[0021] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explaining the present invention and are not intended to limit the present invention.

[0022] Example 1

[0023] like Figure 1-Figure 3 As shown, this embodiment provides an air suction dust removal device for a corrugated cardboard production line, which includes an installation box 110. An extension plate 130 is provided on the side wall of the installation box 110, and an extension plate through-hole 140 is provided on the extension plate 130. A dust collection cylinder mounting seat 310 is rotatably provided in the installation box 110, and a drive motor 210 for driving the dust collection cylinder mounting seat 310 to rotate is provided in the installation box 110; two mounting through-holes 320 are provided in the dust collection cylinder mounting seat 310, and a dust collection cylinder 330 is provided in the mounting through-holes 320. A dust collection bag 340 is provided in the dust collection cylinder 330. An air inlet cylinder 220 is provided on the outer wall of the installation box 110, and a pipe on the air inlet cylinder 220 is connected to the dust collection hopper 120 installed in the workshop. The opening end of the mounting hole 320 at the dust collector mounting base 310 extends toward the inner wall of the mounting box 110 near the side wall of the air inlet cylinder 220 but does not contact the inner wall of the mounting box 110. An air inlet passage 350 is formed between the air inlet cylinder 220 and the dust collector 330 between the extended end of the dust collector mounting base 310 at the opening of the mounting hole 320 and the inner wall of the mounting box 110. An exhaust hole 360 is provided at the bottom end of the dust collector 330; an exhaust cylinder 370 is provided at the side wall of the installation box 110 away from the air inlet cylinder 220, and an exhaust channel 380 is provided in the installation box 110 between the exhaust hole 360 and the exhaust cylinder 370; it also includes a control mechanism, the control mechanism includes a buzzer 510, and the control mechanism is used to form a closed loop with the drive motor 210, the buzzer 510 and the external power supply to drive the dust collector mounting base 310 to rotate after the dust collector 330 moves to the specified position.

[0024] Before use, place the dust hopper 120 near the starch addition point and the slitting machine. Then, connect it to the air intake hopper 220 at the installation box 110 via a duct. During use, connect the exhaust hopper 370 to the air blower via a duct to extract air from the installation box 110. Workshop air enters the air intake hopper 220 through the dust hopper 120 and is discharged from the air intake hopper 220 through the air intake channel 350, the dust collection hopper 330, the exhaust hole 360, the exhaust channel 380, and the exhaust hopper 370. As the workshop air passes through the dust collection hopper 330, it is filtered by the dust bag 340 inside the dust collection hopper 330, thereby reducing dust in the workshop.

[0025] As the amount of dust accumulated in the dust bag 340 increases, the pressure of the air passing through the dust bag 340 gradually increases, thereby pushing the dust collector 330 to move toward the end of the exhaust pipe 370. When the dust collector 330 moves to the specified position, the drive motor 210, the buzzer 510 and the external power supply in the control mechanism form a closed loop to drive the dust collector mounting base 310 to rotate. When the other unused dust collector 330 in the dust collector mounting base 310 rotates to communicate with the air inlet pipe 220, it stops rotating. At this time, the unused dust collector 330 starts to work.

[0026] The suction dust removal equipment for the corrugated cardboard production line in this embodiment, through the setting of the rotating dust collection cylinder mounting base 310 and the control mechanism, can not only automatically replace the dust collection cylinder 330 after a certain amount of dust accumulates in the dust collection bag 340 in the dust collection cylinder 330, but also can alarm through the buzzer 510 during the replacement process, thereby reminding people to replace the dust collection bag 340 in the dust collection cylinder 330.

[0027] In summary, compared to currently common workshop dust removal equipment, the suction dust removal equipment for a corrugated cardboard production line in this embodiment not only automatically replaces the dust collection bag 340 when the dust in the dust collection bag 340 reaches a certain level, thereby enabling the suction dust removal equipment for a corrugated cardboard production line to continuously filter dust from the workshop, thereby improving the purification effect of the workshop air. Furthermore, during the replacement of the dust collection bag 330, the buzzer 510 enters an alarm state, thereby reminding workshop staff to clean the dust collection bag 340 in the dust collection bag 330.

[0028] Combine Figure 4-Figure 8 As shown, the bottom end of the dust collection cylinder 330 is provided with a sealing mechanism for sealing the exhaust through hole 360, and a dust collection cylinder through hole 810 is provided at the center of the bottom wall of the dust collection cylinder 330. The sealing mechanism includes a sliding column 820 slidably arranged in the dust collection cylinder through hole 810, one end of the sliding column 820 extends into the dust collection cylinder 330, and the end of the sliding column 820 extending into the dust collection cylinder 330 is provided with a sealing plate 830, and the other end of the sliding column 820 extends out of the dust collection cylinder through hole 810. A mounting plate 840 is provided at the other end, and a sliding column spring 850 is sleeved on the sliding column 820 and is located between the outer wall of the dust removal cylinder 330 and the mounting plate 840 and is used to pull the sealing plate 830 to abut against the exhaust through hole 360; a first magnet 860 is provided at the end of the mounting plate 840 close to the inner wall of the mounting box 110, and a second magnet 410 is provided in the inner wall of the mounting box 110, which is arranged with opposite magnetic properties to the first magnet 860 and is used to push the sliding column 820 to disengage the sealing plate 830 from sealing the exhaust through hole 360.

[0029] By providing the sealing mechanism, when the dust collector 330 is pulled out of the mounting hole 320, the sliding column spring 850 pulls the sealing plate 830 to abut against the exhaust hole 360, thereby preventing dust in the dust collector 330 from escaping from the exhaust hole 360, thereby effectively improving the stability of the dust collector 330 during use. By cooperating between the first magnet 860 and the second magnet 410, when the dust collector 330 is rotated to the mounting plate 840, the first magnet 860 and the second magnet 410 are close to each other. The repulsive magnetic force between the first magnet 860 and the second magnet 410 pushes the mounting plate 840, i.e., the sealing plate 830, to move, thereby allowing air filtered by the dust bag 340 to be discharged from the dust collector 330 through the exhaust hole 360.

[0030] Combine Figure 9 、 10As shown, the control mechanism includes a first arc-shaped conductive piece 420 and a second arc-shaped conductive piece 430 arranged at the installation box 110. The first arc-shaped conductive piece 420 and the second arc-shaped conductive piece 430 are both semi-circular and respectively arranged at the two ends of the second magnet 410; the mounting plate 840 is provided with a first conductive rod mounting cavity 870 near the first arc-shaped conductive piece 420, and the first conductive rod mounting cavity 870 is provided with an "L"-shaped first conductive rod 880; the second arc-shaped conductive piece 430 extends into the installation box 110 to form a conductive piece extension portion 440, and the mounting plate 840 is provided near the conductive piece extension portion. The portion 440 is provided with a second conductive rod mounting cavity 890, in which a second conductive rod 8100 is provided, and the second conductive rod mounting cavity 890 is also provided with a conductive rod spring 8110 for pushing the second conductive rod 8100 to abut against the conductive sheet extension portion 440; the first conductive rod 880 and the second conductive rod 8100 are electrically connected through a cable; the first conductive rod 880 is used to contact the first arc-shaped conductive sheet 420 so that the first arc-shaped conductive sheet 420, the second arc-shaped conductive sheet 430, the drive motor 210, the buzzer 510 and the external power supply form a closed loop.

[0031] As the amount of dust accumulated in the dust bag 340 increases, the pressure of the air on the dust bag 340 gradually increases when flowing through the dust bag 340, thereby driving the dust bag 340 and the dust collection barrel 330 to move toward the end of the second magnet 410. When the first conductive rod 880 at the mounting plate 840 contacts the first arc-shaped conductive sheet 420, the first arc-shaped conductive sheet 420, the second arc-shaped conductive sheet 430, the drive motor 210, the buzzer 510 and the external power supply form a closed loop, thereby driving the dust collection barrel mounting base 310 to rotate. When the first magnet 860 at the mounting plate 840 is misaligned with the second magnet 410, the first conductive rod 880 is always in contact with the first arc-shaped conductive sheet 420 under the push of the sliding column spring 850. When the first conductive rod 880 at the dust collecting cylinder 330 rotates to disengage from the first arc-shaped conductive sheet 420, at this time, the first conductive rod 880 at the mounting plate 840 on the other dust collecting cylinder 330 rotates to contact the first arc-shaped conductive sheet 420, and the second conductive rod 8100 at the mounting plate 840 on the other dust collecting cylinder 330 rotates to contact the second arc-shaped conductive sheet 430. At this time, the dust collecting cylinder mounting seat 310 will keep rotating. When the first magnet 860 rotates to be close to the second magnet 410, since the dust bag 340 in the dust collector 330 is not in use, the thrust of the wind in the dust collector 330 is small. Under the repulsive magnetic force between the first magnet 860 and the second magnet 410, the mounting plate 840 moves away from the end of the second magnet 410, so that the first conductive rod 880 rotates to be out of contact with the first arc-shaped conductive sheet 420, and the dust collector mounting base 310 stops rotating at this time.

[0032] Through the setting of the control mechanism, the cooperation between the first magnet 860 and the second magnet 410 can not only push the sealing plate 830 to open the exhaust hole 360, but also realize the on and off of the control mechanism circuit, so that the dust collector mounting base 310 can stop when it rotates to the specified position.

[0033] Combine Figure 4 As shown, the inner wall of the mounting through hole 320 is recessed inward to form a strip groove 450 , and a strip plate 460 is provided on the outer wall of the dust removal cylinder 330 to fit in the strip groove 450 with a gap.

[0034] By setting the strip groove 450 and the strip plate 460, the dust removal cylinder 330 can be prevented from rotating on its own in the mounting hole 320, thereby preventing the first conductive rod 880 from being misaligned with the first arc-shaped conductive sheet 420 and the second conductive rod 8100 from being misaligned with the second arc-shaped conductive sheet 430, thereby better improving the stability of the suction dust removal equipment for the corrugated cardboard production line during use.

[0035] Combine Figure 9 As shown, the installation box 110 is provided with a cover 230 covering the first arc-shaped conductive sheet 420 and the second arc-shaped conductive sheet 430, and the cover 230 is provided with a cover opening 910 passing through the side wall of the installation box 110, and the cover opening 910 is used to pull the dust collector 330 out of the installation through hole 320, and the cover opening 910 is set at a position corresponding to the installation through hole 320 away from the second magnet 410 when the dust collector mounting seat 310 stops rotating, and a mounting sleeve 470 is provided at the cover opening 910, and a sealing plate 480 for sealing the cover opening 910 at the installation box 110 is slidably provided in the mounting sleeve 470, and a screw hole 920 communicating with the mounting sleeve 470 is provided at the side wall of the cover 230, and a fixing bolt 490 for fixing the sealing plate 480 is provided in the screw hole 920.

[0036] When the dust collection tube mounting base 310 stops rotating, the fixing bolts 490 can be loosened, and the sealing plate 480 can then be removed to remove the dust collection tube 330 from the mounting hole 320. Since the first conductive rod 880 of the dust collection tube 330 is out of contact with the first curved conductive sheet 420 and the second conductive rod 8100 is out of contact with the second curved conductive sheet 430, there is no risk of electric shock. After removing the dust collection tube 330, the dust bag 340 in the dust collection tube 330 can be replaced to clean the dust collection tube 330. After the dust bag 340 is replaced, the dust collection tube 330 is pushed into the mounting hole 320, and the sealing plate 480 is then covered and fixed with the fixing bolts 490 to clean and replace the dust collection tube 330. This makes it relatively convenient to clean and replace the dust collection tube 330.

[0037] Combine Figure 6 as well as Figure 7 As shown, the dust collector 330 is provided with an installation step 710, and the dust collector 330 is also provided with an internal thread 720 from the open end of the dust collector 330 to the installation step 710. The opening of the dust collector 330 is provided with a threaded cover plate 610 that cooperates with the internal thread 720 and is used to clamp the dust bag 340 together with the installation step 710. The threaded cover plate 610 is provided with a cover plate air inlet 620.

[0038] By providing the threaded cover plate 610 and the mounting step 710 , the dust bag 340 can be placed in the dust removal cylinder 330 more conveniently.

[0039] In this embodiment, a bearing mounting groove 930 is provided in the mounting box 110 , and a bearing 940 located in the bearing mounting groove 930 is sleeved on the dust removal cylinder mounting seat 310 .

[0040] By providing the bearing 940 , the friction between the dust collector mounting base 310 and the inner wall of the mounting box 110 can be reduced better during rotation.

[0041] In this embodiment, a hexagonal blind hole 4100 is provided at the center of the dust collector mounting base 310, and the end of the rotating shaft of the driving motor 210 is provided to extend into the mounting box 110. The end of the rotating shaft of the driving motor 210 extending into the mounting box 110 is provided with a hexagonal connecting shaft 520 that is clearance-matched with the hexagonal blind hole 4100.

[0042] The connection between the rotating shaft of the driving motor 210 and the dust collector mounting seat 310 can be achieved through the clearance fit between the inner hexagonal blind hole 4100 and the hexagonal connecting shaft 520.

[0043] Example 2

[0044] This embodiment provides a method for using the air suction and dust removal equipment for the corrugated cardboard production line described in Example 1, which includes the following steps: Step 1: Open the installation box 110, then place the two dust removal cylinders 330 in the installation through holes 320 respectively, turn on the power of the drive motor 210 to rotate the drive motor 210, and wait for the first magnet 860 at the dust removal cylinder 330 to move to the second magnet 410; the first conductive rod 880 at the dust removal cylinder 330 disengages from the first arc-shaped conductive sheet 420, causing the drive motor 210 to stop rotating; Step 2: Connect the exhaust pipe 370 to the exhaust fan through a pipe, start the exhaust fan, and the air in the workshop is discharged through the air intake pipe 220, the air intake channel 350, the dust bag 340, the exhaust hole 360, the exhaust channel 380, the exhaust pipe 370 and the exhaust fan in sequence, thereby achieving filtration of the workshop air; Step 3: As the amount of dust accumulated at the dust bag 340 increases, the dust collection tube 330 gradually moves toward the second magnet 410. When the first conductive rod 880 contacts the first arc-shaped conductive sheet 420, the dust collection tube mounting base 310 rotates. When the first magnet 860 at the adjacent dust collection tube 330 rotates to the second magnet 410, it stops rotating. Step 4: Remove the sealing plate 480, pull out the dust collection tube 330 and take out the dust collection bag 340 for replacement. After the dust collection bag 340 is replaced, open the sealing plate 480 and insert the dust collection tube 330 with the replacement dust collection bag 340 into the installation hole 320 and install the sealing plate 480 to replace the dust collection bag 340.

[0045] Through the above-mentioned operation method, the dust bag 340 in the dust collection cylinder 330 can be replaced without stopping the machine, which not only makes it convenient for the staff to clean the dust collection cylinder 330, but also better improves the purification effect of the workshop air.

[0046] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
