Description

Technical Field

[0001] The invention relates to the field of corrugated paper printing, and in particular to a dust removal and feeding device for corrugated paper printing. Background Art

[0002] When printing on corrugated paper, dust on the surface will have a negative impact on the printing effect, such as:

[0003] Uneven adhesion: Dust can change the flatness and roughness of the corrugated paper surface, resulting in the ink not being able to adhere evenly to the paper surface.

[0004] Reduced Adhesion: The presence of dust creates a barrier between the ink and the corrugated paper, weakening the adhesion between the ink and the paper. This can cause printed content to peel or fade during subsequent processing, transportation, or use, reducing the durability and quality of the printed product.

[0005] To solve this problem, the prior art proposes a printing paper feeding dust removal device (Announcement No. CN114379215B), which uses a detachable adhesive roller to absorb dust or impurities on the paper. When a large amount of impurities adhere to and collect on the surface of the adhesive roller, the adhesive roller can be replaced. However, this technical solution has the following drawbacks:

[0006] 1. For some dust or impurities with strong stickiness, it is difficult for the adhesive roller to pick them up, and the cleaning effect cannot be achieved well;

[0007] 2. When there are a lot of impurities collected on the surface of the adhesive roller, the machine needs to be stopped for replacement, which affects the working efficiency. Summary of the Invention

[0062] The dust removal and feeding device for corrugated paper printing provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings and through specific embodiments and their application scenarios.

[0063] Embodiment 1:

[0064] As Figures 1 to 5 shown, the embodiment of the present application provides a dust removal and feeding device for corrugated paper printing, including a machine shell 1, a dust cleaning device 2 and two pairs of conveying rollers 3. The dust cleaning device 2 includes a dust removal shell 21, which is installed in the inner cavity of the machine shell 1 and has openings 22 at both ends; several brush rollers 23, which are rotatably installed in the dust removal shell 21 and are driven by a motor; several pulse air pipes 24, which are installed in the dust removal shell 21 and each has several pulse air flow discharge holes 25 facing the adjacent brush rollers 23, and one end extends out of the machine shell 1 and is connected to a pulse gas generator; a collection system 4, which is used to collect the dust in the dust removal shell 21 and has a detachable dust filter bag 41.

[0065] Further, the collection system 4 includes several connecting pipes 42, which are respectively arranged at the top and bottom of each dust removal shell 21; a pair of turntables 43, which are respectively rotatably installed at the top and bottom of the inner cavity of the machine shell 1 by a motor and have several filter holes 44 that can communicate with each connecting pipe 42, and a filter screen 45 is installed in each filter hole 44; a pair of exhaust cavities 46, which are arranged at the top and bottom of the inner cavity of the machine shell 1, are open towards the dust removal shell 21 side and are in contact with the surface of the adjacent turntable 43, and the outside is connected to an exhaust pump 47 through a pipeline; a collection unit 5, which is used to collect the dust and impurities on the filter screen 45 in the filter holes 44 outside the exhaust cavity 46 into the dust filter bag 41.

[0066] Further, the collection unit 5 includes a pair of intake pipes 51, which are installed on the outer wall of the casing 1, with one end extending into the inner cavity of the casing 1 and fitting against the surface of each turntable 43 on the side opposite to the dust removal housing 21; a pair of exhaust pipes 52, which are installed on the outer wall of the casing 1, with one end extending into the inner cavity of the casing 1 and fitting against the surface of each turntable 43 on the side facing the dust removal housing 21; and an exhaust pump II 53, which is installed between the other ends of the pair of exhaust pipes 52, and the exhaust port of the exhaust pump II 53 is threadedly connected to the filter dust bag 41.

[0067] In this embodiment of the present application, due to the adoption of the above structure, both ends of the casing 1 are open. The corrugated cardboard to be cleaned extends into the casing 1 from one end, passes through a pair of conveying rollers 3, then extends into the dust removal housing 21 through the opening 22 on one side of the dust removal housing 21, passes through each brush roller 23, and then extends out of the dust removal housing 21 through the opening 22 on the other side of the dust removal housing 21. After passing through a pair of conveying rollers 3 again, it extends out of the casing 1 and enters an external printing device for printing. When the corrugated cardboard passes through the inner cavity of the dust removal housing 21, at the same time, the pulse gas generator generates a pulse airflow, which passes through each pulse air pipe 24 and is discharged from each pulse airflow discharge hole 25, and blows towards the front and back surfaces of the corrugated cardboard at the same time, disturbing the dust and impurities on the surface of the corrugated cardboard. Each brush roller 23 is driven to rotate by a corresponding motor (not shown in the drawings), sweeping and raising the dust and impurities on the surface of the corrugated cardboard in the inner cavity of the dust removal housing 21. Each exhaust pump I 47 operates, forming a negative pressure in each exhaust cavity 46. The dust and impurities in the dust removal housing 21 are carried by the airflow and enter the corresponding exhaust cavity 46 through some filter holes 44. The dust and impurities in the airflow are blocked by the filter screen 45 in the filter holes 44, and the filtered airflow is discharged out of the casing 1 through a pipeline. At the same time, the exhaust pump II 53 operates, causing the airflow outside the casing 1 to enter the corresponding filter holes 44 from each intake pipe 51. The airflow blows towards the filter screen 45 in the filter holes 44, causing the dust and impurities attached to the filter screen 45 to enter the exhaust pipe 52, and then being sent into the filter dust bag 41 by the exhaust pump II 53. The turntable 43 can be driven to rotate by a corresponding motor, so that each filter hole 44 passes through the space between the exhaust pipe 52 and the intake pipe 51 in sequence. When it is necessary to remove the filter dust bag 41 for cleaning, the motor corresponding to the turntable 43 is stopped, and the exhaust pump II 53 is also stopped. In this way, the filter screens 45 can be cleaned without shutting down the machine.

[0068] Embodiment 2:

[0069] As Figures 2 to 5 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, it further includes a plurality of chutes 61, which are respectively arranged on the surface of each turntable 43 facing the dust removal housing 21 and communicate with the lower part of each filter hole 44; a plurality of sliding members 62, which are slidably installed in pairs in each chute 61, and a brush 63 is installed on the inner side wall of the end facing the filter hole 44; a pair of pushing members 7, which are respectively installed on the top and bottom of the casing 1 and are used to push the corresponding pair of sliding members 62 to reciprocate in the corresponding chutes 61 in opposite directions; and a driving member 8, which is used to drive the pair of pushing members 7 to act synchronously.

[0070] Further, the sliding member 62 includes a sliding housing 621 which is U-shaped, with a return spring 622 installed inside, and a brush 63 is provided at the top near the filter hole 44 end; a stop block 623 which is fixedly arranged in the chute 61, extends into the sliding housing 621, and the outer side wall thereof abuts against the filter hole 44 end of the return spring 622.

[0071] In this embodiment of the present application, due to the adoption of the above structure, when the motor corresponding to the turntable 43 stops operating, the driving member 8 acts to control the pair of pushing and moving members 7 to act, pushing the corresponding pair of sliding housings 621 to reciprocally slide in the corresponding chutes 61 at this time, so that the pair of brushes 63 alternately and reciprocally clean the surface of the filter screen 45 with dust and impurities, improving the cleaning effect on the filter screen 45. When the exhaust pump two 53 stops operating, the driving member 8 controls each pushing and moving member 7 to move away from the corresponding chute 61, and the turntable 43 can rotate under the drive of the corresponding motor, moving the next filter hole 44 between the air inlet pipe 51 and the exhaust pipe 52.

[0072] Embodiment 3:

[0073] As Figure 2 and Figure 4 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, the pushing and moving member 7 includes a hollow shell 71 which is fixedly arranged at the top or bottom of the machine shell 1, and the inner cavity thereof is communicated with the inner cavity of the machine shell 1; a pair of sliding plates 72 which are slidably installed in the hollow shell 71; a pair of racks 73 which are symmetrically installed on the same side surface of the pair of sliding plates 72; a gear 74 which meshes with the pair of racks 73 and is rotatably installed on the inner wall of the hollow shell 71; a connecting member 75 which extends out of the hollow shell 71 through a transverse groove 76 and is in transmission connection with the driving member 8.

[0074] Further, the driving member 8 includes a mounting plate 81 which is fixedly arranged between the pair of hollow shells 71; a pair of swing arms 82, one end of which is hinged to the middle of the mounting plate 81 through a hinge shaft and meshes with each other through a gear set 83, and the other end is in transmission connection with the connecting member 75; a power source for driving one of the swing arms 82 to swing.

[0075] Further, the driving member 8 includes a transmission groove 84 which is arranged on one of the swing arms 82; a transmission disk 85 which is driven to rotate by a motor and is in transmission connection with the transmission groove 84 through a transmission rod 86.

[0076] Further, the connecting member 75 includes a fixing block 751 which is slidably installed in the transverse groove 76 and is fixedly connected to the sliding plate 72 close to the transverse groove 76; a vertical groove 752 which is arranged at the outer end of the fixing block 751; a dial rod 753 which is slidably installed in the vertical groove 752 and is fixedly connected to the end of the adjacent swing arm 82 far from the gear set 83.

[0077] In this embodiment of the present application, due to the adoption of the above structure, the driving disk 85 is driven by a corresponding motor, causing the driving rod 86 to perform a circular motion around the central axis of the driving disk 85, reciprocatingly slide between the two ends of the driving groove 84 and push the swing arm 82 to swing reciprocatingly. A pair of swing arms 82 swing reciprocatingly synchronously through the meshing of the gear set 83. The shift lever 753 at the end of each swing arm 82 slides up and down in the corresponding vertical groove 752 and pushes the corresponding fixed block 751 and the corresponding sliding plate 72 to move. When the sliding plate 72 moves, the corresponding rack 73 meshes with the gear 74, and the other rack 73 is cooperated to drive the other sliding plate 72 to slide in the reverse direction, so that a pair of sliding plates 72 can reciprocatingly enter and exit the sliding groove 61. Cooperating with each return spring 622 can push a pair of sliding shells 621 in the corresponding sliding groove 61 to alternately reciprocatingly expand and contract.

[0078] It should be noted that in this article, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
