Description

Technical Field

[0001] The invention relates to the technical field of cleaning and dust removal, and in particular to a cleaning device for producing packaging cartons. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated paper boxes, single-layer paperboard boxes, etc. In the process of carton production, the paperboard needs to be cut, punched, printed, dyed and bent into boxes. After the paperboard is cut, dust and debris generated during cutting will remain on the surface of the paperboard. In order to facilitate the subsequent processing of the paperboard, the surface of the paperboard is generally cleaned after the paperboard is cut. Since the material of the paperboard is light and easily scratched, the existing device generally uses a flexible brush to clean the surface of the paperboard during cleaning to reduce damage to the paperboard during the cleaning process. However, in the process of using the brush for cleaning, impurities will remain in the gap of the brush. When the amount of impurities remaining in the brush increases, the bending resistance of the brush increases, and the impurities adsorbed on the brush will affect the contact area between it and the paperboard, resulting in a decrease in the cleaning effect of the brush on the paperboard, so that impurities still remain on the cleaned paperboard, affecting the subsequent printing and dyeing effect of the paperboard.

DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The above scheme provides a method for cleaning the accumulated impurities in the brush 5 by loosening the brush 5 after the impurities have accumulated in the brush 5; the conveyor belt 1 is an existing device, and its specific structure and use method will not be described in detail. The conveyor belt 1 is used to drive the cardboard to move from right to left; initially, the upper side of the support frame 2 is in contact with the guide slide bar 3, the connecting plate 4 is provided with a slide groove, and the brush 5 is provided with a slider located in the slide groove of the connecting plate 4 and moving. The brush 5 is an existing device, and its specific structure will not be described in detail. In this embodiment, the first elastic member 6 and the second elastic member 8 are both springs, which are respectively used to push the brush 5 and the sliding frame 7 to move and reset; the second elastic member 8 is used to push the brush 5 and the sliding frame 7 to move and reset; Component 8 is always in a compressed state, and is used to keep the relative position between the sliding frame 7 and the brush 5 stable, so that the sliding frame 7 will not shake at will relative to the brush 5. The extrusion frame 9 is composed of a plurality of cross bars and a U-shaped frame. The cross bars of the extrusion frame 9 are inserted in the soft hair of the brush 5, and are used to loosen the brush 5 when the extrusion frame 9 moves downward, so that the soft hair in the brush 5 squeezes and rubs against each other, thereby accelerating the shedding of impurities. The fixed frame 10 is located on the right side of the supporting frame 2, and the bellows 11 is an existing device, and its specific structure and use method will not be described in detail. A collection box connected to the bellows 11 is provided on the fixed frame 10 for storing impurities cleaned from the brush 5.

[0023] Further, such as Figure 2-Figure 5 As shown, the power assembly includes: an electric push rod 12, which is fixed to the support frame 2, and the telescopic end of the electric push rod 12 passes through the support frame 2; a top plate 1201, which is fixed to the telescopic end of the electric push rod 12, and the top plate 1201 is used to push the sliding frame 7 to move; a corrugated frame 14, which is fixed to the side of the brush 5 close to the sliding frame 7, and the sliding frame 7 is fixed with a convex rod 15, and the corrugated frame 14 is used to guide the convex rod 15, and a plurality of through grooves are provided on the sliding frame 7, and the guide rod 501 is located on the sliding frame 7 and slides in adjacent through grooves.

[0024] The above scheme provides a way to drive the sliding frame 7 to reciprocate relative to the brush 5 in the horizontal direction, squeeze the soft bristles in the brush 5 to make them bend and rub against each other; initially, the telescopic end of the electric push rod 12 is in a retracted state; the corrugated frame 14 drives the sliding frame 7 to reciprocate through the convex rod 15, so that when the sliding frame 7 moves downward relative to the brush 5, it drives the squeezing frame 9 to move horizontally to squeeze the soft bristles in the brush 5, so that the soft bristles in the brush 5 are bent in different directions, thereby increasing the cleaning effect of the squeezing frame 9 on the brush 5.

[0025] Further, such as Figure 2-Figure 5 and Fig. 9As shown, the adjustment component includes: a motor 13, which is fixed to the support frame 2, and the output shaft of the motor 13 passes through the support frame 2; a rotating wheel 1301, which is fixed to the output shaft of the motor 13, and a fixing rod is provided at an eccentric position of the rotating wheel 1301 near the adjacent connecting plate 4, and the fixing rod of the rotating wheel 1301 is rotatably connected to the adjacent connecting plate 4, and the fixing rod of the rotating wheel 1301 is used to drive the connecting plate 4 to reciprocate; a vibration plate 1302, which is fixed to the support frame 2; an L-shaped rod 1303, which is fixed to the brush 5, and the vibration plate 1302 is used to drive the L-shaped rod 1303 to reciprocate in the horizontal direction.

[0026] Further, such as Fig. 9 As shown, the distance between the central axis of the rotating wheel 1301 and the central axis of the fixed rod thereon is greater than two-thirds of the radius of the rotating wheel 1301 .

[0027] Further, such as Figure 5 As shown, the corrugated frame 14 is composed of a corrugated portion and a vertical portion. The distance between the upper and lower adjacent wave crests and wave troughs in the corrugated portion of the corrugated frame 14 in the horizontal direction increases as the distance between the corrugated frame 14 and the brush 5 decreases.

[0028] Further, such as Figure 6-Figure 8 As shown, a clamping block 502 is fixedly connected to the guide rod 501 . The clamping block 502 is provided with an annular inclined surface. The annular inclined surface is used to facilitate its entry into the through groove of the sliding frame 7 . The clamping block 502 is used to limit the sliding frame 7 .

[0029] The above scheme provides a method for driving the brush 5 away from the cardboard and close to the bellows 11 during the cleaning process to reduce the diffusion range of impurities; a torque sensor is arranged on the output shaft of the motor 13, and the torque sensor is used to detect the resistance encountered by the output shaft of the motor 13 when the brush 5 is driven to rotate through the connecting plate 4. A control terminal (not shown in the figure) is arranged on the conveyor belt 1, and the electrical components in this article are all electrically connected to the control terminal, and the switches of the electrical components are all changed through the control terminal. The sensor is electrically connected to the electric push rod 12 through the control terminal. When the data detected by the torque sensor reaches the specified value, the electric push rod 12 is started (the value of the specified value can be set according to the actual situation). Initially, the fixed rod of the rotating wheel 1301 is located at the bottom of the moving direction. When the fixed rod of the rotating wheel 1301 is at the same position as the axis of the rotating wheel 1301, the fixed rod of the rotating wheel 1301 is at the same position as the axis of the rotating wheel 1301. When the brush 1303 is on a horizontal plane, the soft hair of the brush 5 contacts the surface of the cardboard (without applying an extrusion force to the cardboard), and the rotation speed of the output shaft of the motor 13 is greater than the speed at which the conveyor belt 1 drives the cardboard to move, so that the brush 5 will not miss any cardboard during the cleaning process, and the brush 5 can clean the same position of the cardboard multiple times; the vibration plate 1302 is composed of a U-shaped frame and a plurality of protrusions, which are used to push the L-shaped rod 1303 to move back and forth horizontally, adjust the moving direction of the brush 5, and increase the cleaning effect of the brush 5 on the cardboard; the block 502 is used to prevent the sliding frame 7 from moving relative to the brush 5 at will during the normal movement of the brush 5, causing the soft hair in the brush 5 to deform and cause impurities to fall off, resulting in a reduction in the cleaning effect of the cardboard, and the change of the corrugated part on the corrugated frame 14 is used to increase the relative moving distance of the sliding frame 7 and the brush 5, so that the extrusion frame 9 increases the amplitude of the extrusion of the soft hair in the brush 5.

[0030] Workflow: During the process of producing cartons, when the cardboard needs to be cleaned, the staff will place the cardboard on the conveyor belt 1 in turn, and then start the conveyor belt 1, the bellows 11 and the motor 13. The conveyor belt 1 drives the cardboard to move to the left. With the moving direction of the front motor 13 and its parts as a reference, the output shaft of the motor 13 drives the rotating wheel 1301 to rotate counterclockwise ( Figure 2 Looking from the front to the back), the rotating wheel 1301 drives the connecting plate 4 to rotate counterclockwise around the output shaft of the motor 13, and the connecting plate 4 drives the guide slide bar 3 to move back and forth up and down. At this time, the connecting plate 4 is restricted by the guide slide bar 3, and the angle of the connecting plate 4 remains unchanged and moves back and forth left and right relative to the guide slide bar 3. The connecting plate 4 drives the brush 5 to move synchronously, and the brush 5 drives the sliding frame 7 and the parts thereon to move through the second elastic member 8 until the cardboard moves to the bottom of the bellows 11. The bellows 11 extracts external air and preliminarily absorbs impurities on the surface of the cardboard through negative pressure. After the brush 5 contacts the cardboard, the brush 5 continues to move circumferentially and cleans the cardboard when it moves to the right, so that the impurities scattered during the cleaning process move to the right, thereby facilitating the bellows 11 to collect the scattered impurities.

[0031] In the process of the above-mentioned motor 13 driving the rotating wheel 1301 to rotate, when the fixed rod of the rotating wheel 1301 is located above the output shaft of the motor 13, the brush 5 drives the L-shaped rod 1303 to move leftward relative to the vibration plate 1302, the vibration plate 1302 loses contact with the L-shaped rod 1303, the brush 5 and its parts are relatively stationary with the connecting plate 4, and when the fixed rod of the rotating wheel 1301 is located below the output shaft of the motor 13, the brush 5 contacts with the cardboard, and as the connecting plate 4 drives the brush 5 to move synchronously, the brush 5 5 drives the L-shaped rod 1303 to move rightward relative to the vibration plate 1302. When the L-shaped rod 1303 contacts the protrusion on the vibration plate 1302, the L-shaped rod 1303 is squeezed by the protrusion on the vibration plate 1302 to drive the brush 5 to continuously move back and forth and compress the first elastic member 6, so as to adjust the contact position between the brush 5 and the paperboard, thereby improving the cleaning effect of the paperboard. In this process, the brush 5 compresses the first elastic member 6 and drives the sliding frame 7 and the parts thereon to move synchronously through the guide rod 501 and the block 502.

[0032] As the brush 5 cleans the cardboard, when the fixed rod on the rotating wheel 1301 is located at the lowest position where it can move, the torque sensor detects the resistance to the rotation of the output shaft of the motor 13. After the value detected by the torque sensor on the output shaft of the motor 13 reaches the specified value, the output shaft of the motor 13 continues to drive the rotating wheel 1301 to rotate, the electric push rod 12 is started, and the telescopic end of the electric push rod 12 drives the top plate 1201 to move downward. In this process, the output shaft of the motor 13 drives the connecting plate 4 to move upward relative to the top plate 1201 through the rotating wheel 1301, and the connecting plate 4 drives the sliding frame 7 relative to the top plate 1201 through the brush 5. When the top plate 1201 moves upward, after the top plate 1201 contacts the sliding frame 7, the axis of the rotating wheel 1301 is located below the fixed rod thereon. At this time, the brush 5 is separated from the paperboard, reducing the probability of impurities on the brush 5 falling onto the paperboard, which facilitates the subsequent processing of the paperboard. The top plate 1201 pushes the sliding frame 7 to move downward relative to the brush 5. The sliding frame 7 moves downward and compresses the second elastic member 8. The sliding frame 7 drives the extrusion frame 9 and the protruding rod 15 to move downward. The extrusion frame 9 moves downward to loosen the soft hair in the brush 5, so that the impurities gathered in the brush 5 fall off, and the bellows 11 collects the impurities dropped from the brush 5.

[0033] When the brush 5 is lifted up, the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and forth, and the push rod 15 is pushed back and The other parts on the upper part move synchronously. When the protruding rod 15 is separated from the corrugated frame 14, the block 502 enters the through groove of the sliding frame 7 again to complete the limit. The output shaft of the motor 13 continues to drive the rotating wheel 1301 to rotate. When the fixed rod of the rotating wheel 1301 moves to its lowermost part, the torque sensor detects the resistance of the output shaft of the motor 13 to drive the connecting plate 4 to rotate again. If the value detected by the torque sensor is less than the specified value, the telescopic end of the electric push rod 12 will no longer extend. If the value detected by the torque sensor is greater than the specified value, the telescopic end of the electric push rod 12 will extend again to make the extrusion frame 9 clean the brush 5 again. Until the value detected by the torque sensor is less than the specified value, the brush 5 is cleaned. The telescopic end of the electric push rod 12 is retracted and no longer extends. When the brush 5 gathers a large amount of impurities again, the telescopic end of the electric push rod 12 extends again, so that the sliding frame 7 drives the extrusion frame 9 to clean relative to the brush 5 again. After the cleaning of this batch of cardboards is completed, the staff will turn off the turned-on electrical components.

[0034] Further, such as Figure 6-Figure 8 As shown, it also includes: a guiding assembly, which is arranged on the extrusion frame 9 and is used to push the impurities dropped by the brush 5 to move in the direction of the bellows 11. The guiding assembly includes: a scraper 16, which is hinged to the side of the extrusion frame 9 away from the fixed frame 10; a pull rope 17, which is fixed between the scraper 16 and the brush 5, and the pull rope 17 passes through the sliding frame 7. A torsion spring 18 is fixed between the scraper 16 and the extrusion frame 9.

[0035] Further, such as Figure 6-Figure 8 As shown, the elastic coefficient of the torsion spring 18 is smaller than the elastic coefficient of the second elastic member 8 .

[0036] Further, such as Figure 6-Figure 8 As shown, the angle between the scraper 16 and the horizontal plane is less than 30°.

[0037] Further, such as Figure 6-Figure 8 As shown, a fluff block 19 is fixedly connected to one side of the scraper 16 close to the conveyor belt 1, and the fluff block 19 is used to clean impurities that fall onto the plate.

[0038] The above scheme provides a method for guiding the impurities falling off the brush 5 during the process, so that the impurities separated by the brush 5 are collected by the bellows 11, and the impurities dropped by the brush 5 are reduced from gathering on the cardboard again; the scraper 16 is located on the left side of the extrusion frame 9, and the scraper 16 is used to push the dust floating in the process of cleaning the brush 5 to move to the right; the pull rope 17 is used to drive the scraper 16 to rotate, and the torsion spring 18 is used to drive the scraper 16 to rotate counterclockwise ( Figure 2 When viewed from the front to the back, the torsion spring 18 is initially in a state of storing force; the angle between the scraper 16 and the horizontal plane is used to increase the angle of rotation thereof, thereby increasing the total amount of gas pushed by the scraper 16 when it rotates. During the rotation of the scraper 16, the fluff block 19 contacts the surface of the paperboard to clean up the impurities that fall onto the paperboard.

[0039] Working process: In the above process of cleaning the cardboard, when the brush 5 needs to be cleaned, the telescopic end of the electric push rod 12 extends and drives the top plate 1201 to move synchronously. The sliding frame 7 repeats the above process under the action of the top plate 1201 to drive the extrusion frame 9 to move downward and compress the second elastic member 8, so that the extrusion frame 9 repeats the above process to clean the brush 5. In this process, as the sliding frame 7 moves downward relative to the brush 5, the pulling force of the sliding frame 7 on the scraper 16 through the pull rope 17 is reduced, and the torsion spring 18 drives the scraper 16 to rotate counterclockwise to generate a rightward airflow ( Figure 2 (Seen from the front to the back), the scraper 16 drives the fluff block 19 to rotate synchronously and pushes the impurities floating on the brush 5 to move rightward close to the bellows 11 through the airflow, so as to facilitate the collection of impurities and reduce the probability of impurities floating to the cleaned position of the cardboard during the cleaning of the brush 5, causing the cardboard to be contaminated again. As the scraper 16 continues to drive the fluff block 19 to rotate, when the fluff block 19 contacts the cardboard, the fluff block 19 cleans the cardboard for the second time, reducing the probability of impurities falling off the brush 5 accumulating on the surface of the cardboard during the cleaning of the brush 5, affecting the subsequent processing of the cardboard, until the telescopic end of the electric push rod 12 is no longer extended, the sliding frame 7 stops moving, and the scraper 16 stops moving.

[0040] After the scraper 16 stops swinging, the telescopic end of the electric push rod 12 drives the top plate 1201 to move upward and reset, the squeezing force of the top plate 1201 on the sliding frame 7 is reduced, and the second elastic member 8 pushes the sliding frame 7 to move upward relative to the brush 5 and pulls the pull rope 17. The pull rope 17 drives the scraper 16 to rotate in the opposite direction, and the scraper 16 drives the fluff block 19 to rotate synchronously and twist the torsion spring 18 until the sliding frame 7 is separated from the top plate 1201, and the sliding frame 7 stops moving upward relative to the brush 5. Then the telescopic end of the electric push rod 12 repeats the above process to extend and retract, so that the scraper 16 repeats the above process to rotate, until the value detected by the torque sensor decreases to the specified value, the brush 5 is cleaned, and the telescopic end of the electric push rod 12 is retracted and no longer moves.

[0041] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
