Description

Technical Field

[0001] The present application relates to the technical field of tobacco packaging, and in particular to a device for cleaning powder on the side wall of printed paper. Background Art

[0002] A cigarette box is a packaging box used to place tobacco. After the production of the packaging box is completed, the required pattern needs to be printed on the outer wall of the cigarette packaging box through an offset printing machine. After printing, in order to avoid smearing of paint on the outer wall of the cigarette cardboard, it is necessary to spray powder on the outer wall of the cigarette box to reduce damage to the pattern.

[0003] Although powder spraying reduces the damage to the pattern, the excess powder affects the environment. At the same time, since a large amount of powder, paper scraps and even plastic particles are adsorbed on the base paper, if they are not cleaned up, bubble points will form locally in the subsequent processing of the paper, affecting the product quality.

[0004] Existing paper surface dust removal devices generally require manual cleaning, resulting in low cleaning efficiency and affecting the factory working environment. Summary of the invention

[0005] In order to improve the cleaning effect of equipment and reduce powder pollution, the present application provides a cleaning device for the side wall powder of printed paper.

[0006] The present application provides a device for cleaning powder on the side wall of printed paper using the following technical solution: A device for cleaning powder on the side wall of printed paper comprises a workbench and a bracket, wherein the bracket is fixedly connected to the workbench and is located on both sides of the workbench, a conveyor belt is installed on the workbench, a plurality of vacuum suction cups are installed on the conveyor belt, and the vacuum suction cups can adsorb and fix the paper, a cleaning mechanism for cleaning powder on the paper is arranged on the workbench, and a collection box for collecting paper is arranged at the rear end of the workbench.

[0007] By adopting the above technical solution, the paper is fixed by the vacuum suction cup and moved from the previous process to the cleaning mechanism under the conveying action of the conveyor belt. After the powder on the paper is cleaned by the cleaning mechanism, it falls into the collection box for temporary storage, thereby speeding up the cleaning speed of the powder. At the same time, it prevents the powder from diffusing into the air during manual cleaning, thereby improving the cleaning effect and reducing powder pollution.

[0008] Preferably, the cleaning mechanism includes a vacuum cleaner and a dust hood, a top plate is fixedly connected between the two brackets, the dust hood is fixedly mounted on the top plate, the vacuum cleaner is mounted on the workbench, the vacuum cleaner is connected to the dust hood, and the cleaning mechanism also includes a brush that slides on the paper and a driving component that drives the brush to move.

[0009] By adopting the above technical solution, the dust hood expands the cleaning area, and can simultaneously clean the powder on the paper and the powder scattered near the paper and transmitted to the paper. When the vacuum cleaner is vacuuming, the brush slides back and forth on the paper under the action of the driving component, so that the powder that is not firmly attached to the paper can be separated from the paper, which is convenient for the vacuum cleaner to handle, and the cleaning effect is improved with one sweep and one suction.

[0010] Preferably, a through hole for the brush to pass through is opened on the side wall of the bracket, and a hinged door is installed at the through hole. The driving assembly includes a rotating disk and a first motor. The rotating disk passes through and rotates on the bracket and the side wall of the cleaning box. The first motor is installed on the workbench, and the rotation of the first motor is fixedly connected to the rotating disk. Three brushes are provided and evenly installed on the rotating disk. A cleaning box for cleaning the brush is installed on the side of the bracket away from the conveyor belt.

[0011] By adopting the above technical solution, the first motor is set with parameters such as rotation frequency in advance during operation. During the brush cleaning process, the first motor drives the rotating disk to rotate back and forth within a certain angle range, thereby driving the brush to sweep back and forth on the paper. After a period of time, the bristles on the brush are sticky with more powder, which will reduce its cleaning effect. At this time, the first motor rotates 120 degrees and transfers the brush originally sticky with powder into the cleaning box for cleaning. At the same time, a clean brush is rotated out of the cleaning box to continue cleaning the paper.

[0012] Preferably, a cleaning chamber and a drying chamber are provided in the cleaning box, a hinged door for the brush to pass through is provided between the cleaning chamber and the drying chamber, clean water is stored in the cleaning chamber, and a dryer is provided in the drying chamber; a plurality of placement grooves are provided on the rotating disk, a plurality of the brushes are respectively installed in the plurality of placement grooves, a rotating rod is rotatably provided in the placement groove, both ends of the rotating rod are respectively rotatably connected to the relative inner walls of the placement groove, one end of the rotating rod is fixedly connected to the second motor, and the brush is fixedly sleeved on the rotating rod.

[0013] By adopting the above technical scheme, when the brush with powder to be cleaned is turned into the cleaning box through the hinged door, it first enters the cleaning chamber. After the brush enters the cleaning chamber, the second motor is started, and the second motor drives the rotating rod to rotate. The rotating rod rotates to drive the brush to rotate downward into the water. When the rotating disk rotates at a small amplitude and high frequency, the brush in the cleaning chamber moves back and forth in the water, thereby improving the cleaning effect. Before the rotating disk rotates 120 degrees next time, the second motor drives the brush to rotate from a vertical state in the water to a horizontal state. When the rotating disk rotates 120 degrees again, the brush in the cleaning chamber is rotated to the drying chamber through the hinged door for drying, and the brush originally in the drying chamber is rotated out to clean paper, and the brush originally cleaning paper is transferred to the cleaning chamber for cleaning, so that the brush can be cleaned without affecting work efficiency.

[0014] Preferably, a first compaction roller and a second compaction roller are rotatably arranged on the bracket, the first compaction roller and the second compaction roller are in contact with and rotate in coordination with each other, the paper passes between the first compaction roller and the second compaction roller, a third motor and a fourth motor for driving the first compaction roller and the second compaction roller are installed on the side wall of the bracket, and an auxiliary component for conveying paper is arranged on the vacuum suction cup.

[0015] By adopting the above technical solution, after the paper is cleaned by the cleaning mechanism, it continues to move to the tail end of the workbench via the conveyor belt. At this time, with the assistance of the auxiliary component, the paper is inserted between the first compacting roller and the second compacting roller. The paper is compacted by the joint action of the first compacting roller and the second compacting roller, and the powder on the surface that cannot be cleaned off is pressed onto the side wall of the paperboard to prevent the powder from falling off, thereby cleaning the powder more thoroughly.

[0016] Preferably, the auxiliary component includes an abutment plate, a sensor 1 and a control component, the abutment plate slides in the vacuum suction cup, the abutment plate abuts against the paper, the sensor 1 is installed on the bracket, the control component is installed on the vacuum suction cup, and the control component controls the movement of the abutment plate.

[0017] By adopting the above technical solution, when the vacuum suction cup moves to the vicinity of the first compaction roller, when sensor one and the control member are aligned, when the control member receives the signal from sensor one, the control member transmits the signal to the abutment plate, and the abutment plate moves upward to drive one end of the paper to rise, and is tilted to align the height of one end of the paper between the first compaction roller and the second compaction roller. Under the pull of the rotational force of the first compaction roller and the second compaction roller, the paper passes between the first compaction roller and the second compaction roller for compaction operation.

[0018] Preferably, the abutting plate is provided with an inclined surface, a rubber pad is fixedly connected to the inclined surface, and the rubber pad abuts against the paper.

[0019] By adopting the above technical solution, the inclined surface can fit the paper surface more closely, and the rubber pad can increase the friction between the paper and the inclined surface, thereby reducing the possibility of the paper sliding off the inclined surface.

[0023] By adopting the above technical solution, in order to ensure the cleanliness of the surface of the first compaction roller and the second compaction roller, the staff needs to replace the cleaning cloth after a period of time. At this time, the staff pulls the pull rod to drive the compression spring of the plug block to move. When the plug block is disengaged from the slot, the staff can take out the connecting plate, replace the new cleaning cloth, and then pull the pull rod to make the plug block completely in the telescopic slot. After aligning the connecting plate and abutting against the surface of the first compaction roller or the second compaction roller, release the pull rod, and the plug block is inserted into the slot under the action of the spring, thereby fixing the connecting plate.

[0032] The following is combined with Figure 1-6 This application is described in further detail.

[0033] The present application embodiment discloses a device for cleaning powder on the side wall of printed paper, such as Figure 1As shown, it includes a workbench 1 and a bracket 2. A conveyor belt 3 is installed on the workbench 1. The bracket 2 has two rectangular parallelepipeds fixedly welded to the workbench 1 and located on both sides of the conveyor belt 3. A plurality of vacuum suction cups 4 are installed on the conveyor belt 3. The vacuum suction cups 4 can absorb and fix paper. A cleaning mechanism 6 for cleaning powder on paper is provided on the workbench 1. A collection box 5 for collecting paper is placed at the rear end of the workbench 1. The cleaning mechanism 6 includes a dust collector 7 and a dust hood 8. A top plate 9 is fixedly welded between the two brackets 2. The top plate 9 is in a rectangular parallelepiped shape. The dust hood 8 is fixedly installed on the lower end surface of the top plate 9. The dust hood 8 faces the paper below. The dust collector 7 is fixedly installed on the workbench 1 and is connected to the dust hood 8.

[0034] like Figure 1 and Figure 2 As shown, the cleaning mechanism 6 also includes two groups of brushes 10 that slide on the paper and a driving assembly 11 that drives the brushes 10 to move. The two groups of brushes 10 slide on both sides of the paper respectively, so that the entire paper area can be slid and cleaned to avoid missing any position. Two groups of cleaning boxes 16 for cleaning the brushes 10 are fixedly installed on the workbench 1. The two cleaning boxes 16 are placed on the opposite outer sides of the two brackets 2 respectively. A partition is provided in the cleaning box 16. The partition divides the cleaning box 16 into a cleaning chamber 17 and a drying chamber 18. A hinged door 13 for the brushes 10 to pass through is provided on the partition. Clean water is stored in the cleaning chamber 17. The position of the clean water is lower than the position of the hinged door 13. A dryer is provided in the drying chamber 18. Two through holes 12 for the brushes 10 to pass through are provided on the side wall of the bracket 2. The two through holes 12 are symmetrically arranged, and a hinged door 13 is also installed at the through holes 12.

[0035] like Figure 2 and Figure 3 As shown, two sets of driving components 11 are respectively located on both sides of the workbench 1, and the driving component 11 includes a rotating disk 14 and a first motor 15. The rotating disk 14 is cylindrical, and its axis is arranged along the vertical direction. The rotating disk 14 is inserted and rotated in the bracket 2 and the cleaning box 16. The first motor 15 is installed on the lower end surface of the workbench 1, and the rotating shaft of the first motor 15 is fixedly welded to the center of the rotating disk 14. Three brushes 10 are evenly installed on each rotating disk 14, and each brush 10 is 120 degrees apart. The rotating disk 14 has three brushes 10 for placing Slot 19, three brushes 10 are respectively installed in the three placement slots 19, the placement slots 19 are rotatably provided with a rotating rod 20, both ends of the rotating rod 20 are rotatably connected to the opposite inner walls of the placement slots 19, three second motors 38 are installed in the rotating disk 14, the rotating shafts of the three second motors 38 are respectively fixedly welded to one end of the rotating rod 20, and the brush 10 is fixedly sleeved on the rotating rod 20. When the brush 10 is in the cleaning chamber 17, the brush 10 is rotated downward to a vertical state under the action of the second motor 38 and the rotating rod 20, so that the brush 10 can be deeply immersed in water for cleaning.

[0036] like Figure 1 and Figure 2 As shown, the paper is fixed by the vacuum suction cup 4, and moves along with the conveyor belt 3 on the workbench 1 from the previous process to the cleaning mechanism 6. At this time, the vacuum cleaner 7 is started, and the powder on the paper and the powder scattered near the paper are simultaneously adsorbed and cleaned through the dust cover 8. The vacuum suction cup 4 can fix the paper well to avoid the paper moving when the vacuum cleaner 7 is cleaning the powder. At the same time, the first motor 15 drives the rotating disk 14 to rotate at a small amplitude and high frequency, and the rotating disk 14 drives the brush 10 to slide back and forth on the paper, so that the loose powder on the paper can be swept away from the paper, which is convenient for the vacuum cleaner 7 to handle, and the cleaning effect is improved by one sweep and one suction. After a period of time, the bristles of the brush 10 will be stained with more powder, which will reduce its cleaning effect. At this time, the first motor 15 drives the rotating disk 14 to rotate 120 degrees, and the brush 10 originally stained with powder is transferred to the cleaning chamber 17 of the cleaning box 16 for cleaning. At the same time, the brush 10 originally in the cleaning chamber 17 is transferred to the drying chamber 18 for drying. The brush 10 originally in the drying chamber 18 is transferred from the drying chamber 18 through the hinged door 13 to the brush 10 of the last cleaned paper to continue cleaning the paper. When the rotating disk 14 rotates at a small amplitude and high frequency, the brush 10 in the cleaning chamber 17 moves back and forth in the water, thereby improving the cleaning effect. The brush 10 in the drying chamber 18 follows the synchronous reciprocating motion, which can shake off the water on the brush 10 and accelerate the drying effect.

[0037] like Figure 4 and Figure 5 As shown, a first compacting roller 21 and a second compacting roller 22 are rotatably arranged on the bracket 2 at the rear end of the workbench 1. The first compacting roller 21 and the second compacting roller 22 are arranged upper and lower. The first compacting roller 21 is located above the second compacting roller 22. The first compacting roller 21 and the second compacting roller 22 are fitted and rotated in coordination. The paper passes through the first compacting roller 21 and the second compacting roller 22 for compaction. The third motor 23 and the fourth motor 24 for driving the first compacting roller 21 and the second compacting roller 22 are installed on the side wall of the bracket 2. The vacuum suction cup 4 can pass under the second compacting roller 22. An auxiliary component 25 for conveying paper is arranged on the vacuum suction cup 4. The auxiliary component 25 includes an abutment plate 26, a sensor 27 and a control member 28. The abutment plate 26 slides in the vacuum suction cup 4 in the vertical direction. The upper end surface of the abutment plate 26 is provided with an inclined surface 29. A rubber pad 30 is fixedly bonded to the inclined surface 29. The rubber pad 30 abuts against the lower end surface of the paper.

[0038] The sensor 1 27 is mounted on the side wall of the bracket 2, and a plurality of control members 28 are provided and mounted on the side wall of each vacuum suction cup 4. The control member 28 controls the abutment plate 26 to move upward. When the vacuum suction cup 4 moves to the vicinity of the first compaction roller 21, the sensor 1 27 and the control member 28 are aligned, and the control member 28 receives the signal from the sensor 1 27. After receiving the signal, the control member 28 drives the abutment plate 26 to move upward. The movement of the abutment plate 26 drives one end of the paper to rise. At this time, the paper is tilted, and the inclined surface 29 can fit the surface of the paper better. The rubber pad 30 can increase the friction between the paper and the inclined surface 29, thereby reducing the possibility of the paper sliding off the inclined surface 29. When continuing to move toward the first compacting roller 21, the higher end of the paper is aligned between the first compacting roller 21 and the second compacting roller 22, and the paper passes through the first compacting roller 21 and the second compacting roller 22 under the pulling of the rotational force of the first compacting roller 21 and the second compacting roller 22 for compaction operation, and the powder that cannot be cleaned off the surface is pressed onto the side wall of the paperboard to prevent the powder from falling off, thereby cleaning the powder more thoroughly.

[0039] like Figure 4 and Figure 6 As shown, the first compacting roller 21 and the second compacting roller 22 are both provided with a cleaning device for cleaning, the cleaning device includes a cleaning cloth 31 and a connecting plate 32, the cross-section of the cleaning plate is semicircular, the cleaning cloth 31 is fixedly connected to the inner wall of the concave side of the connecting plate 32, the cleaning cloth 31 is divided into a wet area and a dry area, and the connecting plate 32 is detachably connected to the bracket 2. The cleaning device on the first compacting roller 21 is installed above the first compacting roller 21, and the cleaning device on the second compacting roller 22 is installed below the second compacting roller 22. Two plug-in grooves 33 are provided on the opposite side walls of the bracket 2. The two plug-in grooves 33 are arranged at the upper and lower ends. The connecting plate 32 is provided with telescopic grooves 34 at both ends. A plug-in block 35 slides in the telescopic groove 34. The plug-in block 35 is plugged into the plug-in groove 33 along the horizontal direction. A spring 36 is provided in the telescopic groove 34 in the horizontal direction. The two ends of the spring 36 are respectively fixedly welded to the plug-in block 35 and the inner wall of the telescopic groove 34. A pull rod 37 is fixedly welded on the plug-in block 35. A slide groove 39 is provided on the inner wall of the telescopic groove 34. The pull rod 37 extends out of the slide groove 39 and slides in the slide groove 39.

[0040] like Figure 4 and Figure 6As shown, when the first compacting roller 21 and the second compacting roller 22 rotate, after abutting and rotating against the surface of the paper, the rotation will rotate and abut against the wet area and dry area of ​​the cleaning cloth 31 in turn, and the cleaning cloth 31 can clean its surface, and the wet area can improve the cleaning effect, so that the powder adheres to the cleaning cloth 31 in the wet area, and the cleaning cloth 31 in the dry area can not only clean its surface again but also wipe the moisture on its surface. At this time, the cleaning cloth 31 will clean the powder adhered to the paper when the first compacting roller 21 and the second compacting roller 22 compact the paper, reducing the possibility that the powder on the surface of the first compacting roller 21 and the second compacting roller 22 may be reversely adhered to the paper, causing the paper to be contaminated again. In order to ensure the cleanliness of the surface of the first compaction roller 21 and the second compaction roller 22, the staff needs to replace the cleaning cloth 31 after a period of time. At this time, the staff pulls the pull rod 37 to drive the block 35 to compress the spring 36 and move. When the block 35 is disengaged from the slot, the staff can take out the connecting plate 32, replace the new cleaning cloth 31, and then pull the pull rod 37 to make the block 35 completely in the telescopic groove 34. After aligning the connecting plate 32 and abutting against the surface of the first compaction roller 21 or the second compaction roller 22, release the pull rod 37, and the block 35 is inserted into the slot under the action of the spring 36, thereby fixing the connecting plate 32.

[0041] The implementation principle of the embodiment of the present application is as follows: the paper is fixed by the vacuum suction cup 4, and is moved from the previous level process to the cleaning mechanism 6 under the conveying action of the conveyor belt 3. After the powder on the paper is cleaned by the cleaning mechanism 6, it is pressed by the first compacting roller 21 and the second compacting roller 22, and the powder that cannot be cleaned off the surface is pressed onto the side wall of the paperboard to prevent the powder from falling off, thereby cleaning the powder more thoroughly. Afterwards, the pressed paper falls from the first compacting roller 21 and the second compacting roller 22 to the collection box 5 for temporary storage, thereby speeding up the cleaning speed of the powder, and at the same time, preventing the powder from diffusing into the air during manual cleaning, thereby improving the cleaning effect and reducing powder pollution.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
