Description

Technical Field

[0001] The present invention relates to the technical field of top and bottom box processing equipment, and in particular to a top and bottom box processing feeding device. Background Art

[0002] A "top and bottom lid" refers to a type of box. The top of a paper box is the "top," and the bottom is the "bottom," hence the name. Also known as a "top and bottom box," these top and bottom lids are widely used in various packaging applications, including gift boxes, shoe boxes, underwear boxes, shirt boxes, and cell phone boxes. During the production process, cardboard is cut to form the top and bottom boxes. These boxes are then moved to one end of a designated conveyor belt, which then feeds and transports the boxes.

[0003] The existing feeding equipment requires workers to frequently move the top and bottom boxes to be formed when in use, and in order to prevent multiple top and bottom boxes with formed top and bottom from being transported at the same time, the cardboards of several top and bottom boxes to be fed will be fixed in position. The commonly used feeding equipment uses a spring and an extrusion plate to squeeze and clamp the top of the top and bottom boxes to be formed on the workbench. However, when the workers place the top and bottom boxes to be formed, they need to manually adjust the height of the extrusion plate, which is inconvenient to use. Moreover, as the number of top and bottom boxes to be formed gradually decreases, the squeezing force of the extrusion plate on the cardboard of the top and bottom boxes will gradually decrease, resulting in the inability to better define the position of the top and bottom boxes. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a feeding device for processing a top and bottom box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, when the placement plate is lifted or lowered, the lifting plate can drive the support rod and the extrusion rod to move up and down, and the support rod can squeeze the air inside the sleeve when it moves inside the sleeve. When the air pressure inside the sleeve is relatively high, the pressure plate can be driven to move upward, which is convenient for the staff to place the top and bottom box on the top of the installation plate. After the top and bottom box is prevented, as the air inside the sleeve is gradually discharged to the outside through the air outlet, the pressure plate can gradually move downward by its own weight until it squeezes the top and bottom box on the top of the installation plate. During use, the staff cannot manually pick up and place the pressure plate, and the pressure plate squeezes the top and bottom box by its own weight, so the squeezing force on the top and bottom box is more stable, and will not cause damage to the surface of the top and bottom box.

[0019] 2. In the present invention, a large number of top and bottom boxes to be formed can be stacked on top of the placement plate. During use, the staff can drive the placement plate to rise by the electric telescopic rod according to the usage situation, and push a certain number of top and bottom boxes to the top of the installation plate by the push rod. During use, it can prevent the staff from frequently moving the top and bottom boxes, making it more convenient to use. In addition, during use, the installation plate, guide plate, storage box and pressure plate can better fix the top and bottom boxes on the top of the installation plate.

[0020] 3. In the present invention, when the lifting plate moves upward, it can simultaneously drive the squeezing rod to move upward inside the storage barrel, so that the ink stored in the storage barrel is gradually added to the interior of the rubber bag as the placement plate moves upward and the top and bottom boxes are transported. During use, there is no need for workers to frequently add ink to the rubber bag, which is more convenient. Ink is transported to the interior of the rubber bag in stages as the top and bottom boxes are transported.

[0021] 4. In the present invention, when in use, the staff can use the first brush and the second brush connected to the storage box and the rubber bag respectively to oil both sides of the conveyed top and bottom box, thereby preventing scratches, discoloration, and dirt on the surface of the top and bottom box during processing, while increasing the service life of the top and bottom box. In addition, the roller can also oil the bottom of the top and bottom box while conveying the top and bottom box, which is more convenient to use.

[0022] 5. During use, the staff can adjust the height of the storage box according to the thickness of the conveyed top and bottom boxes, which facilitates the movement of the top and bottom boxes between the storage box and the mounting plate. The first brush at the bottom of the storage box can also better oil the top of the top and bottom boxes. During use, the top and bottom boxes located on the top of the mounting plate abut against the side of the storage box. The storage box can limit the placement of the top and bottom boxes on the top of the mounting plate, making the placement of several top and bottom boxes more orderly.

[0036] Baffles 4 are installed on both sides of the top of the mounting plate 1, and a U-shaped pressure plate 27 is installed between the two baffles 4. Fixed blocks 26 are installed at both ends of the pressure plate 27. The fixed block 26 is located above the baffle 4. A guide hole 13 is provided on the top of the baffle 4. The guide hole 13 passes through the baffle 4 and the mounting plate 1. A sleeve 25 is slidably installed in the guide hole 13. The top of the sleeve 25 is installed at the bottom of the fixed block 26. A support rod 24 is slidably installed in the sleeve 25. The bottom end of the support rod 24 is installed on the top of the lifting plate 20 away from the end of the placement plate 6. An air outlet 33 is provided on the top of the inner wall of the sleeve 25. When the placement plate 6 is lifted or lowered, the pressure plate 27 can be driven to lift or lower by the support rod 24 and the sleeve 25.

[0037] As a technical optimization solution of the present invention, a mounting hole 11 is opened on the top of the mounting plate 1, and the mounting hole 11 is located below the pressure plate 27. A motor 12 is installed on the side of the mounting plate 1. The output shaft of the motor 12 passes through the inside of the mounting hole 11 and is rotatably installed on the inner wall of the mounting hole 11. A roller 30 is installed on the output shaft of the motor 12. When in use, the output shaft of the motor 12 can drive the top and bottom box located on the top of the mounting plate 1 for transportation through the roller 30.

[0038] As a technical optimization solution of the present invention, the roller 30 is located inside the mounting hole 11, and a number of anti-slip grooves are provided on the outer wall of the roller 30. A number of second brushes 42 are installed on the inner wall of one side of the mounting hole 11, and one end of the second brush 42 is in contact with the outer wall of the roller 30. The bottom of the mounting plate 1 is located on the side of the mounting hole 11 close to the support plate 2 and is provided with a rubber bag 29. The end of the second brush 42 away from the roller 30 is connected to the interior of the rubber bag 29. During use, the staff can add ink to the inside of the rubber bag 29 according to the usage, and apply ink to the surface of the roller 30 through the second brush 42. When the roller 30 rotates, the ink on the surface of the roller 30 can be applied to the bottom of the top and bottom box, and the bottom of the top and bottom box is oiled.

[0039] As a technical optimization solution of the present invention, storage cylinders 40 are installed at both ends of the bottom of the rubber bag 29, and an extrusion rod 41 is slidably installed inside the storage cylinder 40. The bottom end of the extrusion rod 41 is installed at the top middle end of the lifting plate 20, and the top of the support rod 24 and the extrusion rod 41 are installed with a sealing sleeve 34. The outer walls of the two sealing sleeves 34 are respectively in contact with the inner walls of the sleeve 25 and the storage cylinder 40. During use, as the height of the placement plate 6 gradually rises, the placement plate 6 can drive the extrusion rod 41 to push into the interior of the storage cylinder 40 through the lifting plate 20, so that the ink inside the storage cylinder 40 gradually enters the interior of the rubber bag 29, thereby adding ink to the interior of the rubber bag 29.

[0040] As a technical optimization solution of the present invention, a storage box 28 is installed between the two baffles 4. The storage box 28 is located on the side of the pressure plate 27. An injection hole is opened at the top of the storage box 28. Several first brushes 31 are installed at the bottom of the storage box 28. Connecting blocks 37 are installed at the top of both ends of the storage box 28. The connecting blocks 37 are located above the baffle 4. When in use, the staff can inject ink into the interior of the storage box 28 and apply the ink to the top of the top and bottom box through the first brush 31 at the bottom thereof to oil the top surface of the top and bottom box.

[0041] As a technical optimization solution of the present invention, screw holes 14 are provided at the tops of the two baffles 4, and a threaded rod 38 is installed on the top of the connecting block 37. The bottom end of the threaded rod 38 passes through the connecting block 37 and is threadedly installed in the screw hole 14. An adjustment block 39 is installed on the top of the threaded rod 38, and the connecting block 37 is rotatably installed on the threaded rod 38. The two ends of the storage box 28 are respectively abutted against the opposite surfaces of the two baffles 4. When in use, the staff can adjust the height of the storage box 28 through the adjustment block 39, the threaded rod 38 and the connecting block 37. When in use, the staff can adjust the distance between the bottom of the storage box 28 and the mounting plate 1 according to the width of the top and bottom box, so as to facilitate the transportation of the top and bottom box.

[0042] As a technical optimization solution of the present invention, sliding holes 7 are opened on both sides of the opposite surfaces of the two protective plates 3 in the length direction, and a sliding plate 8 is slidably installed in the sliding hole 7. One end of the sliding plate 8 is installed on the side of the placement plate 6. A plurality of guide strips 22 are installed on the side of the support plate 2 close to the placement plate 6 in the length direction, and the guide strip 22 is located between the two placement holes 9. When the electric telescopic rod 10 drives the placement plate 6 to rise and fall, the sliding plate 8 can play a better guiding role in the movement of the placement plate 6 through the sliding hole 7, so that the placement plate 6 is more stable when rising and falling.

[0043] As a technical optimization solution of the present invention, the tops of the two protective plates 3 are provided with slide grooves 17 in the length direction, and a slider 21 is slidably installed in the slide groove 17. The tops of the protective plates 3 are slidably installed with push rods 18. The top ends of the two sliders 21 are respectively slidably installed on the two ends of the bottom of the push rods 18. When the top and bottom box located on the top of the placement plate 6 moves to the specified height, the staff can push the push rod 18, and the push rod 18 pushes the top and bottom box on its side to move between the two guide plates 19 on the top of the mounting plate 1.

[0044] As a technical optimization solution of the present invention, the opposite surfaces of the two baffles 4 are both equipped with guide plates 19 near one end of the support plate 2, and the pressure plate 27 is located between the guide plate 19 and the storage box 28. A plurality of rubber strips 32 are installed at the bottom of the pressure plate 27 in the length direction. A fixing hole 15 is opened at the end of the mounting plate 1 away from the support plate 2, and a conveyor belt 16 is installed inside the fixing hole 15. When in use, the pressure plate 27 can squeeze the top and bottom box located on the top of the mounting plate 1 by its own weight, so that the surface of the top and bottom box is smoother during transportation, and can also squeeze the gas inside the sleeve 25 by its own weight, so that the gas inside the sleeve 25 is gradually discharged to the outside through the air outlet 33, and the pressure plate 27 can slowly move downward.

[0045] As a technical optimization solution of the present invention, limiting grooves 35 are provided on the opposite surfaces of the two baffles 4, and limiting blocks 36 are slidably installed in the limiting grooves 35. The ends of the two limiting blocks 36 away from the inner walls of the limiting grooves 35 are respectively installed at the two ends of the storage box 28. Several supporting legs 23 are installed on both sides of the bottom of the mounting plate 1. When in use, the side of the sky and earth box located at the top of the mounting plate 1 abuts against the side of the storage box 28, and the sky and earth box located at the bottom can be transported through the bottom of the storage box 28. The limiting blocks 36 can better limit the position of the storage box 28 through the limiting grooves 35.

[0046] When the present invention is in use, the staff stacks the unformed top and bottom boxes on the top of the placement plate 6 and pushes the top and bottom boxes so that the sides of the top and bottom boxes abut against several guide strips 22 on the sides of the support plate 2. When in use, the top and bottom boxes located on the top of the placement plate 6 can be made more neat, and the staff can push the push rod 18 located on the top of the protective plate 3 so that the push rod 18 pushes the top and bottom boxes on the top of the placement plate 6 that are higher than the height of the protective plate 3 to the top of the mounting plate 1. When in use, the two guide plates 19 located on the opposite sides of the two baffles 4 can clamp and limit the position of the top and bottom boxes located on the top of the mounting plate 1, and when in use, the side of the top and bottom boxes located on the top of the mounting plate 1 abut against the side of the storage box 28. When in use, the guide plates 19 and the storage box 28 cooperate with each other to better fix the position of the top and bottom boxes located on the top of the mounting plate 1.

[0047] During use, the height of the storage box 28 can be adjusted by the operator according to the thickness of the top and bottom boxes. The operator rotates the adjustment block 39, which drives the threaded rod 38 to rotate. Because the connecting block 37 on the storage box 28 is rotatably mounted on the threaded rod 38, and the bottom end of the threaded rod 38 is threadedly mounted in the screw hole 14 at the top of the baffle 4, the threaded rod 38 rotates to move the storage box 28 up and down, and the connecting block 37 drives the storage box 28 up and down at the same time. During use, the distance between the bottom of the storage box 28 and the mounting plate 1 can be adjusted, making it easier to feed unformed top and bottom boxes through the bottom of the storage box 28.

[0048] During use, the staff starts the motor 12, and the output shaft of the motor 12 drives the roller 30 located inside the mounting hole 11 at the top of the mounting plate 1 to rotate. When the top and bottom box is placed on the top of the mounting plate 1, the bottom of the top and bottom box abuts against the top outer wall of the roller 30, and the outer wall surface of the roller 30 is provided with anti-slip grooves, so when the roller 30 rotates, it can drive the top and bottom box abutting against the top of the mounting plate 1 to be transported toward the storage box 28, and move between the storage box 28 and the mounting plate 1 to the top of the conveyor belt 16 to feed the unformed top and bottom box.

[0049] During use, a worker can store a certain amount of ink in both the storage box 28 and the rubber bladder 29. The first brush 31 and the second brush 42 are connected to the interiors of the storage box 28 and the rubber bladder 29, respectively. As the roller 30 rotates, the second brush 42 applies ink from the rubber bladder 29 to the surface of the roller 30. As the roller 30 rotates and drives the top and bottom boxes through the anti-slip grooves on its surface, the ink is applied to the bottom of the top and bottom boxes. As the top and bottom boxes move between the storage box 28 and the mounting plate 1, the first brush 31 at the bottom of the storage box 28 applies ink from the storage box 28 to the top surface of the top and bottom boxes. During use, the first brush 31 and the second brush 42 oil both sides of the top and bottom boxes, preventing scratches, discoloration, and dirt from forming during processing and increasing the service life of the top and bottom boxes.

[0050] When the top and bottom box on the top of the mounting plate 1 is used up, the staff can use the electric telescopic rod 10 to drive the placement plate 6 to rise until the top and bottom box on the top of the placement plate 6 is higher than the protective plate 3 by a certain amount. The staff can then push the push rod 18 again to drive the top and bottom box higher than the protective plate 3 to move to the top of the mounting plate 1. During use, the staff does not need to frequently carry the unformed top and bottom box, which is more convenient to use.

[0051] When the placement plate 6 is raised, the placement plate 6 drives the lifting plate 20 on its side to slide in the placement hole 9 on the support plate 2. At the same time, the lifting plate 20 pushes the support rod 24 at its top to move into the sleeve 25 at the bottom of the fixed block 26, and the support rod 24 can quickly squeeze the air inside the sleeve 25. When the pressure of the air inside the sleeve 25 is too high, the support rod 24 can drive the sleeve 25, the fixed block 26 and the pressure plate 27 to rise through the lifting plate 20, and the staff can push the top and bottom box to the top of the installation plate 1 through the push rod 18, and the raised pressure plate 27 is located above the top and bottom box at the top of the installation plate 1.

[0052] Because the outer wall of the sleeve 25 is provided with an air outlet 33 with a small diameter, when the pressing plate 27 rises, the pressing plate 27 can again press down the sleeve 25 by its own weight and the weight of the fixing block 26, so that the air inside the sleeve 25 is gradually discharged to the outside through the air outlet 33. As the air inside the sleeve 25 is discharged, the pressing plate 27 can move downward toward the mounting plate 1 until the bottom of the pressing plate 27 abuts the top of the sky box located on the top of the mounting plate 1. When the pressing plate 27 and the sleeve 25 move up and down, the guide holes 13 located on the baffle 4 can effectively guide the movement of the sleeve 25 and the pressing plate 27, making the pressing plate 27 more stable during the lifting and lowering movement.

[0053] During use, as the number of boxes on top of mounting plate 1 gradually decreases, air inside sleeve 25 is gradually discharged to the outside through air outlet 33, ensuring that the bottom of pressure plate 27 always contacts the top of the boxes. This allows the surface of the boxes to be formed to be smoother. At the same time, the pressure of pressure plate 27 on the boxes allows the boxes in contact with mounting plate 1 to better contact the outer wall of roller 30, facilitating the rotation of roller 30 to transport the boxes.

[0054] As the lifting plate 20 rises, it pushes the squeeze rod 41 on its top to move upward within the storage cartridge 40. This upward movement of the squeeze rod 41 transfers the ink within the storage cartridge 40 into the rubber bladder 29. When ink is added to the rubber bladder 29, the ink flows into the storage cartridge 40, where it remains ready for use. As the placement plate 6 rises and the top and bottom boxes move, the squeeze rod 41 gradually transfers the ink from the storage cartridge 40 into the rubber bladder 29. Because the rubber bladder 29 is mounted at the bottom of the mounting plate 1, the gradual flow of ink from the storage cartridge 40 into the rubber bladder 29 eliminates the need for frequent ink additions, enhancing convenience. The location of the storage cartridge 28 above the mounting plate 1 allows for convenient access to the ink reservoir 28.

[0055] When the top and bottom boxes on the top of the placement plate 6 are delivered, the staff can use the electric telescopic rod 10 to gradually move the placement plate 6, the support rod 24 and the squeeze rod 41 downward. While the placement plate 6 is moving downward, the staff can move the remaining top and bottom boxes to be fed. When the placement plate 6 approaches the bottom plate 5 and stops moving, the staff can place the top and bottom boxes on the top of the placement plate 6. At the same time, when the placement plate 6 gradually moves downward, the outside air can enter the interior of the sleeve 25 through the air outlet 33. During use, there is no need for the staff to manually adjust the height of the pressing plate 27. The pressing plate 27 can gradually rise and then move downward as the placement plate 6 moves, making it easier for the staff to place the top and bottom boxes and also better clamping and fixing the top and bottom boxes in place.

[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
