Technical Field

[0001] This utility model relates to the field of cardboard box feeding technology, specifically to an automatic cardboard box alignment and feeding device. Background Technology

[0002] Cardboard boxes are widely used in goods packaging and transportation. Current cardboard boxes are made by folding and gluing cardboard. The current production process generally involves first cutting the cardboard, then applying glue and folding the cut cardboard to form the box. After cutting, the stacked cardboard is often manually placed into the feeding port of the cardboard gluing and folding production line, and then fed via a conveyor belt.

[0003] When cardboard is conveyed on a conveyor belt, it is easy for it to deflect or slip, making it difficult to align the angle and position of the cardboard during feeding, which affects the subsequent processing steps of folding and packaging. Utility Model Content

[0004] The purpose of this invention is to provide an automatic carton alignment and feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic carton alignment and feeding device, comprising a base, a conveyor belt on the upper surface of the base, a drive roller inside the conveyor belt, one end of the drive roller being fixedly connected to a transmission wheel, a bidirectional lead screw inside the base, a limiting plate above the conveyor belt, two symmetrical supports fixedly connected to the upper surface of the base, an mounting plate inside the supports, a top surface of the mounting plate being rotatably connected to one end of a threaded rod, a side surface of the mounting plate being fixedly connected to one end of a rotating shaft, the outer side of the rotating shaft being fixedly connected to the limiting roller, a placement frame fixedly connected to the upper surface of the base, a feeding roller below the placement frame, a transmission wheel on one side of the feeding roller, a fixed plate fixedly connected to the upper surface of the placement frame, a fixed box fixedly connected to the side of the fixed plate, an adjusting screw inside the adjusting box, and a baffle at the bottom of the adjusting screw.

[0006] Preferably, a rectangular through groove is formed on the upper surface of the base, the conveyor belt is located above the rectangular through groove, and one end of the bidirectional lead screw is rotatably connected to the inner wall of the rectangular through groove.

[0007] Preferably, the two sides of the bidirectional lead screw are provided with opposite threads, and two mutually symmetrical movable plates are provided on both sides of the bidirectional lead screw. The movable plates are L-shaped plates, and the movable plates slide in the rectangular through groove. The side of the movable plates is threaded to the outer side of the bidirectional lead screw through threaded holes, and the top of the movable plates extends above the conveyor belt and is fixedly connected to the limiting plate.

[0008] Preferably, a rectangular through hole is provided on the side of the bracket, the mounting plate slides with the bracket through the rectangular through hole, and the bracket is threadedly connected to the threaded rod through a threaded hole.

[0009] Preferably, the upper surface of the placement frame has a rectangular through hole for placing the top of the feeding roller. The feeding roller is fixedly connected to the outside of the connecting shaft. The feeding roller is rotatably connected to the placement frame through the connecting shaft. The second transmission wheel is fixedly connected to one end of the connecting shaft. The second transmission wheel is connected and fixed to the first transmission wheel through a synchronous belt.

[0010] Preferably, the adjusting box is rotatably connected to the adjusting screw, the inside of the adjusting box is slidably engaged with the moving block, and the moving block is threadedly connected to the adjusting screw through a threaded hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses limiting plates on both sides to automatically align the cardboard on the conveyor belt, uses limiting rollers to adhere to the cardboard surface to ensure stable conveying, uses the rotation of the bidirectional screw to move the moving plates on both sides to adjust the distance between the limiting plates, and uses the threaded rod to move the mounting plate up and down in the bracket to adjust the height of the limiting rollers, which facilitates the alignment and feeding of cardboard with different radii and thicknesses.

[0012] 2. This utility model can also place cardboard inside the placement rack. The rotation of the drive roller causes the transmission wheel one to rotate via the synchronous belt, which in turn causes the transmission wheel two to rotate, further causing the feeding roller to rotate and drive the cardboard in the placement rack to move towards the conveyor belt, thus realizing feeding and transportation. By rotating the adjusting screw, the moving plate moves in the adjusting box, causing the baffle to move up and down, adjusting the height of the discharge hole at the bottom of the fixed plate, so as to facilitate the sequential and individual transportation of cardboard of different thicknesses.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an automatic carton alignment and feeding device, including a base 1, with support feet at the bottom of the base 1, the upper surface of the base 1 being welded and fixed to the outer frame of the conveyor belt 2, a motor being fixedly installed on the side of the outer frame, the output end of the motor being fixedly connected to a drive roller 3, the upper surface of the base 1 being welded and fixed to a feeding plate, and the feeding plate and the placement frame 13 being located at both ends of the conveyor belt 2 respectively. A rectangular through groove is formed on the upper surface of the base 1. The conveyor belt 2 is located above the rectangular through groove. One end of the bidirectional lead screw 5 is rotatably connected to the inner wall of the rectangular through groove. Opposite threads are provided on both sides of the bidirectional lead screw 5. Two mutually symmetrical movable plates 6 are provided on both sides of the bidirectional lead screw 5. The movable plates 6 are L-shaped plates and slide in fit with the inside of the rectangular through groove. The side of the movable plates 6 is threaded to the outer side of the bidirectional lead screw 5 through threaded holes. The top of the movable plates 6 extends above the conveyor belt 2 and is welded and fixed to the limiting plate 7. One end of the limiting plate 7 extends outward at an angle, and the side of the limiting plate 7 is smooth. One end of the drive roller 3 is welded and fixed to the transmission wheel 4. The transmission wheel 4 is connected and fixed to the transmission wheel 15 via a synchronous belt. The teeth of the synchronous belt and the grooves of the teeth of the transmission wheels 4 and 15 ensure the stability of the transmission ratio. The upper surface of the base 1 is welded and fixed to two symmetrical brackets 8. Rectangular through holes are opened on the sides of the brackets 8. The mounting plate 9 slides through these rectangular through holes and is slidably fitted to the brackets 8. The brackets 8 are threadedly connected to the threaded rod 10 through threaded holes. The top surface of the mounting plate 9 is rotatably connected to one end of the threaded rod 10. The side of the mounting plate 9 is welded and fixed to one end of the rotating shaft 11. Several limiting rollers 12 are welded and fixed to the outer side of the rotating shaft 11. By rotating the threaded rod 10, the mounting plate 9 can move up and down within the rectangular through holes, thus adjusting the height of the limiting rollers 12. An elastic layer is provided on the outer side of the limiting rollers 12 to ensure that when one end of the cardboard contacts the limiting roller 12, the elastic layer can be compressed, allowing the limiting roller 12 to better adhere the cardboard to the surface of the conveyor belt 2. The upper surface of the base 1 is welded and fixed to the placement frame 13. A rectangular through hole is opened on the upper surface of the placement frame 13 for placing the top of the feeding roller 14. The feeding roller 14 is welded and fixed to the outside of the connecting shaft. The feeding roller 14 is rotatably connected to the placement frame 13 through the connecting shaft. The transmission wheel 15 is welded and fixed to one end of the connecting shaft. The upper surface of the placement frame 13 is welded and fixed to the fixing plate 16. A discharge hole is opened at the bottom of the fixing plate 16. The side of the fixing plate 16 is welded and fixed to the adjusting box 17. The adjusting box 17 is rotatably connected to the adjusting screw 18. The interior of the adjusting box 17 is slidably fitted with the moving block 19. The moving block 19 is threadedly connected to the adjusting screw 18 through a threaded hole. Working principle: In use, the worker places the cardboard with the feeding tray inside the placement rack 13. The cardboard is limited within the placement rack 13 by the fixing plate 16. The motor drives the drive roller 3 to rotate the conveyor belt 2 and the first transmission wheel 4. The first transmission wheel 4 and the synchronous belt rotate the second transmission wheel 15, so that the second transmission wheel 15 and the feeding roller 14 rotate synchronously. By utilizing the contact between the outer side of the feeding roller 14 and the bottom surface of the cardboard, the rotation of the feeding roller 14 can drive the cardboard through the discharge hole at the bottom of the fixing plate 16 and move it to the surface of the conveyor belt 2 for conveying. The cardboard on the conveyor belt 2 is limited by the limiting plates 7 on both sides to prevent the cardboard from moving during the conveying process. In cases where misalignment occurs due to deflection, the limiting roller 12 is used to adhere the cardboard to the surface of the conveyor belt 2 for positioning, making the cardboard conveying more stable and improving the accuracy of cardboard alignment and feeding. If cardboard of different thicknesses needs to be fed, the rotating screw 18 is adjusted to move the moving block 19 inside the adjusting box 17, which drives the baffle 20 to move up and down, thereby changing the height of the discharge hole at the bottom of the fixed plate 16 to match the thickness of the cardboard being fed, and ensuring that the discharge hole can only accommodate one cardboard at a time. The rotating threaded rod 10 causes the mounting plate 9 to move up and down within the bracket 8, thereby adjusting the height of the limiting roller 12 to meet the needs of cardboard of different thicknesses.
