Description

Technical Field

[0001] This utility model relates to the field of cardboard box transportation technology, specifically a lifting mechanism for cardboard box conveying. Background Technology

[0002] In modern production and logistics processes, cardboard boxes play an indispensable role as the primary carrier for product packaging and transportation. After the items inside the cardboard boxes are removed, these boxes often need to be recycled and reused for both environmental and cost control reasons.

[0003] Existing equipment typically transports cartons via a feeding roller conveyor. When the cartons reach the designated position, a cylinder installed below the roller conveyor is controlled to simultaneously lift four lifting columns at the four corners of the bottom of the cartons, thereby raising the cartons to a designated height for subsequent transport and transfer by the unloading roller conveyor.

[0004] However, as the lifting column raises the carton while the carton moves on the feeding roller line, the carton's position may shift when the lifting column contacts the bottom of the carton. This can cause the carton to fail to reach the designated position accurately, and the unloading roller line may fail to transfer the carton precisely, resulting in production line jams. At this point, workers need to manually adjust the position of the carton, which greatly reduces production efficiency and increases labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a lifting mechanism for carton conveying, so as to solve the problem mentioned in the background art that the position of the carton will shift when the carton is lifted, making it impossible for the carton to be lifted to the designated position.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lifting mechanism for conveying cartons includes: a main body with a feeding roller conveyor and a cylinder inside the feeding roller conveyor, the output end of the cylinder having a fixed block; a fixing component mounted on the fixed block, including a lifting plate mounted on the fixed block, a pressing plate mounted on the lifting plate, a shaped crank mounted on the pressing plate, and a baffle mounted on the shaped crank; the fixing component is used to fix the cartons; and a buffer component mounted on the baffle, including a rotating plate mounted on the baffle, a buffer plate mounted on the rotating plate, and a spring mounted on the buffer plate; the buffer component is used to protect the cartons.

[0008] Preferably, the fixing component further includes a sliding column disposed at the bottom of the pressing plate, and the lifting plate is provided with a through hole corresponding to the sliding column. The sliding column is movably disposed in the through hole, and the through hole matches the sliding column.

[0009] Preferably, an elastic element is provided between the lifting plate and the pressing plate, and the elastic element is located on the outside of the sliding column.

[0010] Preferably, a rotating component is provided on one side of the sliding column, and a connecting crank is rotatably connected to the rotating component. One end of the irregularly shaped crank is located on the side of the connecting crank away from the rotating component, and the middle part of the irregularly shaped crank is rotatably connected to the lifting plate.

[0011] Preferably, one end of the irregularly shaped crank is rotatably connected to a connecting rod, and one end of the connecting rod is rotatably connected to a connecting block. A baffle is fixedly mounted on the connecting block at the end away from the connecting rod.

[0012] Preferably, a trapezoidal block is fixedly connected to the bottom of the connecting block, and a trapezoidal groove is provided on the lifting plate corresponding to the trapezoidal block, with the trapezoidal block movably disposed in the trapezoidal groove.

[0013] Preferably, the buffer assembly further includes a connecting groove disposed on the baffle, a rotating plate rotatably connected to both sides inside the connecting groove, and two sets of springs disposed in the middle of the side of the buffer plate near the connecting groove.

[0014] Preferably, a mounting block is rotatably connected to the end of the rotating plate away from the connecting groove, and a sliding groove is provided on the buffer plate corresponding to the mounting block, with the mounting block movably disposed in the sliding groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the carton moves to the top of the cylinder on the feeding roller line, the cylinder is activated, which causes the lifting plate to lift the carton. When the carton contacts the lifting plate, the carton will press down on the pressing plate due to its gravity. This will cause the baffle to fix the two sides of the carton through the special-shaped crank, thereby fixing the position of the carton and effectively preventing the carton from shifting. This allows the carton to be transported to the designated position.

[0017] When the baffles secure the carton, to prevent excessive clamping force from the two sets of baffles, the spring force and the buffer plate work together to protect the carton and prevent the baffles from damaging it when securing it. Attached Figure Description

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figure 1 - Figure 9 As shown, this application provides a lifting mechanism for carton conveying, including a device body 1, a feeding roller line 2 disposed on the device body 1, a cylinder 3 disposed inside the feeding roller line 2, a fixing block 4 disposed at the output end of the cylinder 3, and further including:

[0031] The fixing block 4 is provided with a fixing component, which includes a lifting plate 5 set on the fixing block 4, a pressing plate 6 set on the lifting plate 5, an irregularly shaped crank 13 set on the pressing plate 6, and a baffle 11 set on the irregularly shaped crank 13. The fixing component is used to fix the carton.

[0032] Specifically, such as Figure 4 As shown, the fixing assembly also includes a sliding column 7 disposed at the bottom of the pressing plate 6. The lifting plate 5 is provided with a through hole 18 corresponding to the sliding column 7. The sliding column 7 is movably disposed in the through hole 18. The through hole 18 matches the sliding column 7. The setting of the pressing plate 6 facilitates the sliding column 7 to descend when the carton contacts the lifting plate 5.

[0033] Specifically, such as Figure 4 As shown, an elastic element 8 is provided between the lifting plate 5 and the pressing plate 6. The elastic element 8 is located on the outside of the sliding column 7. The elastic force of the elastic element 8 can drive the pressing plate 6 to retract to its original position after the carton is transferred away.

[0034] Specifically, such as Figure 6 As shown, a rotating component 15 is provided on one side of the sliding column 7, and a connecting crank 14 is rotatably connected to the rotating component 15. One end of the irregular crank 13 is provided on the side of the connecting crank 14 away from the rotating component 15. The middle part of the irregular crank 13 is rotatably connected to the lifting plate 5. By the falling of the sliding column 7, the irregular crank 13 can be driven to rotate.

[0035] Specifically, such as Figure 6 As shown, one end of the irregular crank 13 is rotatably connected to the connecting rod 12, and one end of the connecting rod 12 is rotatably connected to the connecting block 10. The baffle 11 is fixedly installed on the connecting block 10 at the end away from the connecting rod 12. By rotating the irregular crank 13, the baffle 11 can be driven to clamp and fix the carton, which can effectively prevent the carton from shifting position during the upward movement.

[0036] Specifically, such as Figure 6 As shown, a trapezoidal block 16 is fixedly connected to the bottom of the connecting block 10, and a trapezoidal groove 17 is provided on the lifting plate 5 corresponding to the trapezoidal block 16. The trapezoidal block 16 is movably disposed in the trapezoidal groove 17. Through the cooperation of the trapezoidal block 16 and the trapezoidal groove 17, the movement direction of the connecting block 10 can be limited.

[0037] A buffer assembly is provided on the baffle 11. The buffer assembly includes a rotating plate 19 provided on the baffle 11, a buffer plate 9 provided on the rotating plate 19, and a spring 21 provided on the buffer plate 9. The buffer assembly is used for the protection of the carton.

[0038] Specifically, such as Figure 9As shown, the buffer assembly also includes a connecting groove 20 provided on the baffle 11. The rotating plate 19 is rotatably connected to both sides inside the connecting groove 20. Two sets of springs 21 are provided in the middle of the side of the buffer plate 9 near the connecting groove 20. Through the elastic force of the springs 21, the carton can be protected when the baffle 11 clamps and fixes it, so as to avoid damage to the carton due to excessive clamping force.

[0039] Specifically, such as Figure 9 As shown, a mounting block 22 is rotatably connected to one end of the rotating plate 19 away from the connecting groove 20. A sliding groove 23 is provided on the buffer plate 9 corresponding to the mounting block 22. The mounting block 22 is movably disposed in the sliding groove 23. Through the cooperation between the mounting block 22 and the sliding groove 23, the rotating plate 19 can be prevented from getting stuck when rotating.

[0040] In this embodiment: the carton is lifted by the lifting plate 5, and the weight of the carton itself can drive the pressing plate 6 to descend, thereby causing the sliding column 7 to descend as well. This can drive the irregular crank 13 to rotate, so that the irregular crank 13 can drive the connecting block 10 to move towards the carton through the connecting rod 12, so that the baffle 11 can fix the carton, thereby preventing the carton from shaking during the upward movement. Through the cooperation of the spring 21 and the rotating plate 19, the clamping force of the baffle 11 on the carton can be reduced, thereby preventing the carton from being damaged when it is fixed.

[0041] Specifically, when the carton is conveyed to the top of the cylinder 3 via the feeding roller conveyor 2, the cylinder 3 is controlled to lift the carton off the feeding roller conveyor 2 via the lifting plate 5. When the carton contacts the lifting plate 5, its weight causes it to press against the pressing plate 6, which in turn causes the pressing plate 6 to descend the sliding column 7. This causes the sliding column 7 to rotate via the rotating component 15, which in turn rotates the irregularly shaped crank 13. This, in turn, causes the connecting block 10 to move towards the carton via the connecting rod 12. Due to the cooperation between the trapezoidal block 16 and the trapezoidal groove 17, the movement direction of the connecting block 10 will not change. Since the lifting plate 5 is equipped with baffles 11 on both sides, the two sets of baffles 11 can clamp and fix the carton at the same time, thereby preventing the carton from shifting position during the lifting process and allowing it to rise smoothly to the designated position. During the process of fixing the carton with the baffles 11, the cooperation between the spring 21 and the rotating plate 19 can reduce the clamping force of the baffles 11 on the carton, thereby protecting the carton and preventing damage to the carton during the fixing process.

[0042] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
