Description

Technical Field

[0001] This application relates to the field of cardboard box processing, and more particularly to cardboard box bulk strip packaging technology, specifically to a cardboard box bulk strip packaging equipment. Background Technology

[0002] The general production process of corrugated cardboard boxes is as follows: preheating and softening, corrugation forming, gluing and shaping, cooling and curing, cutting and finishing, printing and crease pressing, and bundling. When bundling cardboard boxes in batches, the corrugated cardboard with creases and printing is typically stacked and then placed on the worktable of a bundling machine, which then bundles the stacked cardboard. Currently, in the process of batch bundling cardboard boxes, the cardboard from the previous process is usually collected manually, stacked manually, and placed on the worktable of the bundling machine for bundling. The bundled cardboard is then manually removed from the machine. This method is inefficient, especially with large cardboard volumes, and consumes significant labor and time costs, making it difficult to match the processing efficiency of the entire cardboard box production line. Furthermore, manual stacking makes it difficult to achieve neat stacking, and the bundling strips can easily leave creases on the edges of the cardboard, affecting the integrity and aesthetics of the final cardboard box.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a bulk strip packaging equipment for cartons, including a strip packaging machine 1. The strip packaging machine 1 includes a machine housing 11 and a working frame 12 disposed on the upper surface of the machine housing 11. The strip packaging machine 1 and its working principle are existing technologies, so they will not be described in detail here. The equipment also includes a conveying mechanism 2, a side limiting mechanism 3, and a rotating mechanism 4.

[0028] Specifically, such as Figures 1-3As shown, there is a pair of conveying mechanisms 2. Each conveying mechanism 2 includes a drive plate 21 and a pair of first conveyor belts 22. The surfaces of the drive plates 21 are parallel to the side of the chassis 11 and are movable along the width direction of the chassis 11. The distance between the drive plates 21 and the bottom of the chassis 11 is adjustable. Two mounting plates 23 are provided on the opposite side of the two drive plates 21. Each mounting plate 23 is provided with a first rotating motor 24 whose axis is parallel to the length direction of the chassis 11. The first rotating motors 24 on the same drive plate 21 are coaxially arranged and their drive shafts are opposite to each other. The drive shafts of the first rotating motors 24 are respectively connected to one end of the first conveyor belts 22. The conveying surfaces of the first conveyor belts 22 are parallel to the length direction of the chassis 11, and the conveying directions of the first conveyor belts 22 are perpendicular to the length direction of the chassis 11. The first rotating motors 24 are used to drive the first conveyor belts 22 to rotate.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the side limiting mechanism 3 includes two pairs of side plates 31. The surface of the side plates 31 is parallel to the end face of the chassis 11. The side plates 31 are all movable along the length direction of the chassis 11. The lower part of the side plates 31 is in sliding contact with the upper surface of the chassis 11. The same pair of side plates 31 are located at both ends of the upper surface of the chassis 11, and different pairs of side plates 31 are located on both sides of the working frame 12.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the rotating mechanism 4 is located above the housing 11. The rotating mechanism 4 includes a pair of suction plates 41. The surface of the suction plates 41 is parallel to the upper surface of the housing 11. The distance between the suction plates 41 and the upper surface of the housing 11 is adjustable. Each suction plate 41 has a suction cup 42 on its lower surface. Each suction cup 42 is connected to a ventilation hose 43. More specifically, the ventilation hose 43 is connected to an external air pressure control mechanism to control the air pressure inside the suction cup 42, so that the suction cup 42 can adhere to the cardboard. Each suction plate 41 is rotatably arranged around a rotating axis. The rotating axis is coaxial with the central axis of the housing 11 parallel to its own height direction. The central axis of the two suction plates 41 is coplanar with the rotating axis. The distance between the suction plates 41 and the rotating axis is adjustable.

[0031] During operation, two conveying mechanisms 2 are defined as the first conveying mechanism 2 and the second conveying mechanism 2, respectively. The first rotating motor 24 drives the conveyor belt 22 of the first conveying mechanism 2 to rotate, making the conveying surface of the conveyor belt 22 parallel to the upper surface of the housing 11. The distance between the drive plate 21 of the first conveying mechanism 2 and the bottom of the housing 11 is adjusted. The cardboard processed in the previous process falls onto the conveyor belt 22 of the first conveying mechanism 2 and is stacked. When the number of cardboard pieces reaches the predetermined quantity for single-bundle packaging, the falling of the cardboard stops. The distance between the drive plate 21 of the first conveying mechanism 2 and the bottom of the housing 11 is adjusted. The bottom spacing is maintained. The stacked cardboard is conveyed to the surface of the housing 11 by the conveyor belt 22. The first rotating motor 24 drives the conveyor belt 22 to rotate, so that the conveying surface of all the conveyor belts 22 is perpendicular to the width direction of the housing 11. Two drive plates 21 move along the width direction of the housing 11, and side plates 31 move along the length direction of the housing 11. The side plates 31 and the conveyor belt 22 respectively contact the four sides of the stacked cardboard to drive the cardboard to be stacked neatly. The movement of the conveyor belt 22 drives the stacked cardboard to move on the housing 11. The working frame 12 performs strip bundling and packaging of the stacked cardboard at different positions. After bundling stacked cardboard strips from one direction, and when bundling from another direction is required, the suction plate 41 is moved downwards so that the suction cup 42 contacts the topmost cardboard. The suction cup 42 adheres to the cardboard through the ventilation hose 43. The suction plate 41 is rotated around the rotating axis. Once it reaches the corresponding position, the suction cup 42 is released through the ventilation hose 43, and the suction plate 41 is raised. At this point, the stacked cardboard can be bundled from the other direction. After the cardboard bundling is completed, the second conveying mechanism 2 is driven by the corresponding first rotating motor 24. The first conveyor belt 22 rotates, making its conveying surface parallel to the upper surface of the housing 11. At the same time, the distance between the drive plate 21 of the second conveyor mechanism 2 and the bottom of the housing 11 is adjusted so that the conveying surface of the second conveyor belt 22 is lower than the upper surface of the housing 11. The first conveyor belt 22 is moved to push the cardboard bundled on the housing 11 onto the second conveyor belt 22. The second conveyor belt 22 drives the cardboard bundled to move, so that the cardboard bundled leaves the equipment, thus completing the unloading process.

[0032] Preferred, such as Figures 1-3As shown, the device also includes a base plate 5, with a chassis 11 mounted on the base plate 5. The base plate 5 has two first electric lead screws 25 whose driving direction is parallel to the width direction of the chassis 11. Each first electric lead screw 25 is threadedly fitted with a first mating block 26. Each first mating block 26 has a first linear cylinder 27 whose driving direction is parallel to the height direction of the chassis 11. The conveying mechanism 2 also includes an L-shaped frame 28, which includes a horizontal section and a vertical section. The vertical section is parallel to the height direction of the chassis 11 and connected to the drive shaft of the first linear cylinder 27. The upper end of the vertical section, facing the chassis 11, is connected to the horizontal section. The horizontal section is parallel to the width direction of the chassis 11, and one end of the horizontal section is connected to a drive plate 21. The first electric lead screws 25 are used to drive the corresponding drive plate 21 to move along the width direction of the chassis 11, and the first linear cylinders 27 are used to adjust the distance between the corresponding drive plate 21 and the bottom of the chassis 11.

The pressure control chamber 415 is located on the upper surface of the rotating plate 49. The air supply hose 43 is connected to the corresponding pressure control chamber 415. The air pump 413 is used to adjust the air pressure in the suction cup 42 through the air supply pipe 414, the pressure control chamber 415, and the air supply hose 43, so as to control the adsorption relationship between the suction cup 42 and the cardboard.

[0036] Preferred, such as Figure 7 As shown, a support ring 416 is connected below the mounting bracket 44. A mating groove 417 is provided on the inner wall of the support ring 416.

The shaped block 419 fits in the shaped groove 418. The fit between the shaped block 419 and the shaped groove 418 is used to reduce the load on the second rotating motor 45 when it is working and to avoid damage to the second rotating motor 45.

[0037] Preferred, such as Figure 1 , Figure 2 , Figures 8-10As shown, the device also includes a rectangular storage compartment 6, located on one side of the chassis 11. More preferably, the bottom of the storage compartment 6 has a certain distance from the base plate 5, which can be achieved by vertically arranged support columns. A first conveying mechanism 2 is located between the storage compartment 6 and the chassis 11. A lifting plate 61 is movable along its own height direction inside the storage compartment 6, with the surface of the lifting plate 61 parallel to the upper surface of the storage compartment 6. The four sides of the storage compartment 6 are defined as the first side, the second side, the third side, and the fourth side. The first side is parallel to the fourth side, the second side is parallel to the third side, and the first side faces the first conveying mechanism 2 and is open. A matching baffle 62 is slidably attached to the first side. A support plate 618 extends outward from the temporary storage compartment 6. A fifth linear cylinder 619 with a driving direction parallel to the height direction of the temporary storage compartment 6 is provided on the support plate 618. The driving axis of the fifth linear cylinder 619 is connected downward to a driving block 620. The driving block 620 is connected to a driving rod 621, and the driving rod 621 is connected to the baffle 62.

The conveying direction of the second conveyor belt 65 is perpendicular to the first side. The second conveyor belt 65 is used to contact the cardboard and drive the cardboard to move out from the first side.

[0038] During operation, since the strip bundling process requires a certain amount of time, a temporary storage bin 6 is set up here to temporarily store the cardboard processed in the previous step when the conveying mechanism 2, side limiting mechanism 3, and rotating mechanism 4 are used in conjunction with the strip bundling packaging machine 1 for strip bundling. During the strip bundling process, the lifting plate 61 is moved so that it is located at the bottom of the temporary storage bin 6, while the temporary storage frame 622 continuously receives cardboard from the previous step. After the strip bundling is completed, the push plate 626 is moved, and the push plate 626 pushes the cardboard through the inlet 63 into the temporary storage bin 6, where it rests on the lifting plate 61. The lifting plate 61 is then raised so that the cardboard on the top layer is connected to the second conveying mechanism. The first conveyor belt 22 is driven by the second conveyor belt 65 to pass through the first side and fall onto the first conveyor belt 22. The lifting plate 61 is moved upward in sequence so that each piece of cardboard contacts the second conveyor belt 65 and is removed from the temporary storage bin 6. When the number of cardboards on the first conveyor belt 22 reaches the predetermined number of single bundle packaging, the driving of the second conveyor belt 65 is stopped. At the same time, the conveying mechanism 2, the side limiting mechanism 3, and the rotating mechanism 4 cooperate with the bundle packaging machine 1 to perform bundle packaging.
