Description

Technical Field

[0001] The invention belongs to the field of logistics and transportation, and in particular relates to a paper box packaging and transportation device for digital printing. Background Art

[0002] A paper box is a three-dimensional shape, which is formed by moving, stacking, folding and surrounding several faces. It is a multi-faceted shape. In the manufacturing process of paper boxes, pulp is usually selected as the raw material. It has good load-bearing capacity and recyclability, and is often used to hold items. Paper boxes have a wide range of uses. They can be used to package various commodities, such as food, cosmetics, electronic products, etc., and to a large extent, they are used to promote and beautify commodities with their exquisite shapes and decorations to improve the competitiveness of commodities.

[0003] The patent with the patent authorization announcement number CN213564648U discloses a carton sealing and transporting device with anti-deviating function, including a bottom plate, one end of which is provided with a first driven roller, and one end of which passes through the bottom plate and is connected to a first transmission wheel. Although the above patent can clamp the carton by the squeezing roller to prevent the carton from deviating during transportation, the carton is in continuous contact with the squeezing roller during the entire transportation process. This long-term close contact state will inevitably cause friction with the side of the carton when the squeezing roller continues to rotate. This continuous friction will gradually accumulate even at normal transportation speed and pressure, and eventually cause the material on the side of the carton to wear out.

[0004] Therefore, a digital printing paper box packaging and transportation device is particularly needed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0033] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Embodiment: A paper box packaging and transportation device for digital printing, such as Figure 1-Figure 13 As shown, it includes a base 1, a support block 11, a transport roller 12, a first transport belt 13, a mounting seat 14, a first motor 15, a controller 3 and a centering mechanism 4. The two support blocks 11 are distributed front and back and connected to the upper left side of the base 1 by welding. The two mounting seats 14 are distributed front and back and connected to the upper right side of the base 1 by bolts. The first motor 15 is connected to the right part of the front mounting seat 14 by bolts, and its output shaft faces backward. The two transport rollers 12 are symmetrically distributed, and the left transport roller 12 is rotatably connected between the upper parts of the two support blocks 11. The right transport roller 12 is arranged between the rear mounting seat 14 and the first motor 15, and its front end is fixedly matched with the output shaft of the first motor 15, and the rear end is rotatably matched with the rear mounting seat 14. The first transport belt 13 is rotatably connected between the two transport rollers 12. The controller 3 is connected to the left front part of the base 1 by bolts and is electrically connected to the first motor 15. The centering mechanism 4 for straightening the paper box is arranged between the two mounting seats 14, and also includes an adsorption mechanism 2 for sucking the paper box, which is arranged between the front support block 11 and the first transport belt 13.

[0035] like Figure 1 and Figure 8-Figure 10As shown, the centering mechanism 4 includes a slide plate 41, a centering plate 42, a roller 421, an electric push rod 43, a movable frame 44 and a hinge rod 45. Each slide plate 41 is slidably connected to each mounting seat 14 by means of a slide rail and a slider. The centering plate 42 is slidably connected to each slide plate 41 by means of a slide rail and a slider. A plurality of rollers 421 aligned transversely form a group and are rotatably connected to one side of each centering plate 42. When the carton passes through the two centering plates 42 for alignment, the two rollers 421 rotate with the movement of the carton, thereby reducing the friction between the two centering plates 42 and the carton and avoiding the side wear of the carton. Each electric push rod 43 electrically connected to the controller 3 is connected to the left part of each mounting seat 14 by means of bolts, with its telescopic end facing right. Each movable frame 44 is connected to the telescopic end of each electric push rod 43 by welding. Two transversely aligned hinge rods 45 form a group and are rotatably connected between the corresponding centering plate 42 and the corresponding movable frame 44.

[0036] like Figure 1-Figure 7 , Fig.12 and Fig.13 As shown, the adsorption mechanism 2 includes a connecting plate 21, a second conveyor belt 22, a suction cup 23, a filter screen 24, an air storage box 26, a connecting pipe 261, an air suction component and an exhaust component. A plurality of connecting plates 21 are equidistantly distributed along the running direction of the first conveyor belt 13, and are connected to the surface of the first conveyor belt 13 by welding. The second conveyor belt 22 is connected between the plurality of connecting plates 21 by welding and encircles the first conveyor belt 13. A plurality of suction cups 23 are equidistantly distributed along the running direction of the second conveyor belt 22, and are connected to the second conveyor belt 22 by welding. Every four suction cups 23 aligned longitudinally form a group, and the adsorption end of each suction cup 23 is flush with the surface of the second conveyor belt 22 to ensure that the paper box contacts the surface of the second conveyor belt 22 while also contacting the adsorption end of the suction cup 23. A plurality of air storage boxes 26 are equidistantly distributed along the running direction of the first conveyor belt 13 by welding. The connecting plate 21 increases the connection area between the air storage box 26 and the first conveyor belt 13, thereby enhancing the stability of the connection. Each filter 24 is connected to the inside of each suction cup 23 by welding to prevent external dust and other impurities from entering the inside of the air storage box 26 from the suction cup 23. Each connecting pipe 261 is connected to each suction cup 23 by welding. Every four connecting pipes 261 aligned longitudinally form a group and are connected to the corresponding air storage box 26, so that each group of suction cups 23 is connected to the corresponding air storage box 26 through each group of connecting pipes 261. An exhaust component for extracting the gas inside the air storage box 26 is arranged between the front support block 11 and the front of the air storage box 26. An exhaust component for exhausting the gas inside the air storage box 26 is arranged between the rear support block 11 and the rear of the air storage box 26.

[0037] like Figure 3-Figure 6 , Fig.12 and Fig.13 As shown, the air extraction assembly includes a special-shaped plate 25, a piston cylinder 27, a piston rod 271, a piston block 272, a first spring 273, a protruding rod 274 and a first air delivery pipe 28.

Each piston cylinder 27 is connected to the front of each air storage box 26 by bolts, and each piston block 272 is slidably connected to the inside of each piston cylinder 27. Each piston rod 271 is connected to the front end of each piston block 272 by welding, and its front end passes through the corresponding piston cylinder 27 and slides with it. Each first spring 273 is sleeved on the outside of each piston rod 271 and is located in the corresponding piston cylinder 27. Its two ends are fixedly connected to the corresponding piston cylinder 27 and the corresponding piston block 272 respectively. Each protruding rod 274 is connected to the front end of each piston rod 271 passing through the corresponding piston cylinder 27 by welding, and is located in the special-shaped plate 2 5, each first gas delivery pipe 28 is connected between the corresponding gas storage box 26 and the corresponding piston cylinder 27 by welding. When the gas storage box 26 drives the piston cylinder 27 to rotate counterclockwise with the second conveyor belt 22, so that the protruding rod 274 is aligned with the protruding portion of the special-shaped plate 25, the protruding rod 274 is pressed backward by the protruding portion, the first spring 273 is in a compressed state, and the piston rod 271 drives the piston block 272 to move backward to discharge the gas inside the piston cylinder 27. Similarly, the protruding rod 274 When aligning with the recessed part of the special-shaped plate 25, the first spring 273 assists the piston rod 271 to drive the piston block 272 to move forward, and the gas inside the air storage box 26 is drawn into the piston cylinder 27. The protruding rod 274 is reset as the piston rod 271 moves forward, and the left end of the front center plate 42 is close to the connection between the protruding part and the recessed part of the special-shaped plate 25, so that when the paper box block is misaligned with the center plate 42, the protruding rod 274 is just offset from the protruding part of the special-shaped plate 25 and aligned with the recessed part of the special-shaped plate 25.

[0038] like Figure 4 , Figure 5 , Figure 7 and Fig.12As shown, the exhaust assembly includes an arc plate 221, an exhaust pipe 29, a slide bar 292, a moving pipe 293, a second spring 294, a trigger rod 296 and a second air delivery pipe 210. The arc plate 221 is connected to the rear support block 11 by welding, and its front edge is in contact with the rear edge of the second conveyor belt 22. Each exhaust pipe 29 is connected to the rear of each air storage box 26 by bolts. A plurality of exhaust holes 291 distributed in a circular array are grouped as a group and are opened at the rear end of each exhaust pipe 29. Each slide bar 292 is slidably connected to the inside of each exhaust pipe 29. Each moving pipe 293 is connected to the rear end of each exhaust pipe 29.

Each second spring 294 is sleeved on the outside of each slide bar 292, and its two ends are respectively fixedly connected to the corresponding exhaust cylinder 29 and the movable cylinder 293. A plurality of exhaust grooves 295 are distributed in a circular array as a group, which are opened at the rear end of each movable cylinder 293 and located behind a corresponding group of exhaust holes 291. The exhaust holes 291 are designed as a circular structure, and the exhaust grooves 295 are designed as a square structure. The exhaust grooves 295 with a square structure are larger in size than the exhaust holes with a circular structure. 291, ensuring that when the two are aligned, a complete gas exhaust channel can be formed. Each trigger rod 296 is slidably connected to the rear part of each exhaust cylinder 29, and its rear end is located outside the corresponding exhaust cylinder 29 and exceeds the front edge of the arc plate 221, and the front end contacts the rear edge of the corresponding moving cylinder 293. Each second gas delivery pipe 210 is connected between the corresponding gas storage box 26 and the corresponding exhaust cylinder 29 by welding. When the exhaust cylinder 29 drives the trigger rod 296 to rotate counterclockwise with the second conveyor belt 22 to the vicinity of the arc plate 221, the trigger rod 296 contacts the arc plate 221 and The trigger rod 296 is squeezed forward and squeezes the movable cylinder 293 forward, so that a group of exhaust grooves 295 are aligned with a group of exhaust holes 291 to form a gas exhaust channel. The gas inside the gas storage box 26 is discharged from the gas exhaust channel through the second gas pipe 210, and the front edge of the arc plate 221 is chamfered to reduce the friction and impact when the trigger rod 296 contacts the arc plate 221. At the same time, the rear end of the trigger rod 296 is designed as a hemispherical structure. The arc surface of the structure can contact the arc plate 221 in advance, ensuring that the trigger rod 296 has a smooth transition during the rotation process, further reducing the impact.

When the second motor 51 is running, the screw 52 rotates to drive the threaded block 53 to drive the slide 41 to move.

[0040] like Figure 1 , Fig.11 and Fig.12 As shown, it also includes a transmission mechanism 6 for blocking the connecting pipe 261, which is arranged between the two screw rods 52 and the air storage box 26. The transmission mechanism 6 includes a guide rod 62, a slide 63, a third spring 64, a push plate 65, a moving rod 66, a pulley 67, a stopper 68 and a fourth spring 69. The two guide rods 62 aligned laterally form a group and are connected to the upper part of the corresponding mounting seat 14 by welding. Each slide 63 is slidably connected between each group of guide rods 62 and is resisted by the corresponding threaded block 53, so that the threaded block 53 can push the slide 63 when it moves. Each third spring 64 is sleeved on the outside of each guide rod 62, and its two ends are respectively fixedly connected to the corresponding mounting seat 14 and the corresponding slide 63.

The two moving rods 66 Distributed front and back, slidably connected to each air storage box 26, one end of each moving rod 66 is located inside the corresponding air storage box 26, and the other end is located outside the corresponding air storage box 26, each pulley 67 is rotatably connected to the other end of each moving rod 66, and is aligned with the corresponding push plate 65 for sliding contact therewith, when the air storage box 26 drives the moving rod 66 to rotate counterclockwise with the second conveyor belt 22, the pulley 67 rotates counterclockwise with the moving rod 66, and slides in contact with the corresponding push plate 65 to rotate, thereby reducing the friction between the moving rod 66 and the push plate 65 to avoid wear, each stopper 68 is connected to one end of each moving rod 66 by welding, and is located inside the corresponding air storage box 26 for contact therewith, each fourth spring 69 is sleeved on one end of each moving rod 66, and its two ends are respectively fixedly connected to the corresponding air storage box 26 and the corresponding stopper 68.

[0041] like Figure 5 and Fig.13As shown, it also includes a filtering mechanism 7 for filtering dust and impurities, which is arranged on the first air pipe 28. The filtering mechanism 7 includes a first connecting block 71, a second connecting block 72, a sliding sleeve 73, a bolt 74 and a filter element 75. Each first connecting block 71 is connected to each first air pipe 28 by welding, and each second connecting block 72 is connected to each first air pipe 28 by welding. Each sliding sleeve 73 is slidably connected to the outside of the corresponding second connecting block 72, and its front part is in contact with the corresponding first connecting block 71. Each bolt 74 is threadedly connected between the corresponding first connecting block 71 and the corresponding sliding sleeve 73, so that the sliding sleeve 73 is fixed on the corresponding first connecting block 71. Each filter element 75 is placed inside each sliding sleeve 73 and is located between the corresponding first connecting block 71 and the corresponding second connecting block 72.

[0042] First, the base 1 is placed between two production lines, ensuring that the right end of the second conveyor belt 22 is aligned with the discharge end of the previous production line, and the left end is aligned with the feed end of the next production line. Then, the first motor 15 is started through the controller 3, and its output shaft drives the right conveyor roller 12 to rotate counterclockwise, and cooperates with the left conveyor roller 12 to drive the first conveyor belt 13 to rotate counterclockwise. The second conveyor belt 22 rotates counterclockwise with the first conveyor belt 13 through the connecting plate 21, ready to receive the paper boxes from the previous production line;

[0043] When the previous production line transports the carton to the right end of the second conveyor belt 22, the bottom surface of the carton immediately contacts and blocks one or more groups of suction cups 23 (how many groups of suction cups 23 can be blocked is determined according to the horizontal length of the carton). At this time, the two electric push rods 43 are immediately started, and their telescopic ends are controlled to extend to a suitable position, driving the two moving frames 44 to move to the right, pushing the four hinged rods 45 to rotate, and the four hinged rods 45 push the two centering plates 42 to move inward to a suitable position, contacting and aligning the carton to ensure that the carton maintains the correct position during transportation. After alignment, the telescopic ends of the two electric push rods 43 are controlled to shorten to the initial position, driving the two moving frames 44 to move to the left, pulling the four hinged rods 45 to reverse, and the four hinged rods 45 pull the two centering plates 42 to move outward to separate from the carton;

[0044] As the second conveyor belt 22 rotates, the carton is transported to the left and staggered between the two centering plates 42. At the same time, one or more protruding rods 274 corresponding to one or more groups of suction cups 23 are separated from the protruding part of the special-shaped plate 25 and aligned with the concave part of the special-shaped plate 25. The first spring 273 returns to its original state, prompting one or more piston rods 271 to drive one or more piston blocks 272 to move forward, and the gas inside one or more gas storage boxes 26 is extracted through one or more first gas pipes 28, thereby generating negative pressure inside one or more gas storage boxes 26, so that one or more groups of suction cups 23 generate suction force, sucking the bottom surface of the carton and fixing it on the second conveyor belt 22, so as to prevent the carton from deviating after being separated from the alignment of the two centering plates 42;

[0045] During the gas extraction process, the extracted gas first passes through one or more filter elements 75 to remove dust and impurities, thereby ensuring the purity of the gas and preventing dust and impurities from entering one or more piston cylinders 27 and causing negative effects (for example, dust and impurities adhere to the inner wall of the piston cylinder 27, increasing friction and wear between the piston block 272);

[0046] When the carton is transported to a suitable position and is about to enter the next production line, one or more trigger rods 296 corresponding to one or more groups of suction cups 23 contact the arc plate 221 in turn and are squeezed forward, thereby squeezing one or more moving cylinders 293 to move forward, and the second spring 294 is compressed accordingly, thereby aligning one or more groups of exhaust grooves 295 with one or more groups of exhaust holes 291 to form multiple gas exhaust channels. At this time, the gas in one or more gas storage boxes 26 is discharged from the multiple gas exhaust channels through one or more second gas pipes 210, thereby generating positive pressure inside one or more gas storage boxes 26, causing one or more groups of suction cups 23 to stop sucking the bottom surface of the carton, ensuring that the carton enters the next production line at the right time. At this point, the transportation process of a carton is completed.

[0047] If the longitudinal length of the paper box is too short, even if the two centering plates 42 are moved inward to the limit position, they cannot be touched for correction. The positions of the two centering plates 42 are adjusted in advance, and the two second motors 51 are started to drive the two screws 52 to rotate synchronously clockwise, driving the two threaded blocks 53 to drive the two slides 41 to move inward, and the two centering plates 42 move inward with the two slides 41 to meet the correction requirements of smaller paper boxes. At the same time, the two threaded blocks 53 push the two slides 63 to move inward, and the third spring 64 is compressed accordingly, and the two push plates 6 The second motors 51 are automatically sealed when the longitudinal length of the paper box is too short to block only two suction cups 23 in a group of suction cups 23, ensuring that negative pressure can be normally generated inside the air storage box 26. After adjusting the positions of the two centering plates 42, the two second motors 51 are turned off.

[0048] When the filter element 75 needs to be replaced, the bolts 74 are directly unscrewed to release the fixation between the first connecting block 71 and the sliding sleeve 73, and then the sliding sleeve 73 is moved backward to be sleeved on the second connecting block 72. After the sliding sleeve 73 is separated from the filter element 75, the filter element 75 falls directly, and finally a new filter element 75 is placed between the first connecting block 71 and the second connecting block 72, and the sliding sleeve 73 is slowly moved forward to sleeve the filter element 75, and the bolts 74 are screwed on.

[0049] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
