Description

Technical Field

[0001] This invention relates to the field of cardboard box manufacturing technology, and in particular to an integrated cardboard box transfer clamp. Background Technology

[0002] In the process of cardboard box manufacturing, the transfer of paper rolls is a critical link. Paper rolls are usually transported and positioned through a dedicated conveyor system to ensure that each roll of paper is accurately delivered to each processing stage of the production line.

[0003] In traditional cardboard box production, paper roll transfer often relies on clamping forklifts for short-distance handling, but this method has some problems; First, the way the forklift clamps the paper roll cannot be effectively integrated with the cardboard unwinding mechanism of the carton forming machine, making the process of joining the paper roll with the cardboard forming machine after handling complicated and inefficient. The size and weight of the paper roll often require manual intervention, which not only increases the difficulty of manual operation, but also leads to a significant increase in the labor intensity of the operators. In particular, the stability and precise positioning of the paper roll are difficult to guarantee during the handling process. In addition, the traditional method usually relies on manual handling to move paper rolls from the storage area to the unwinding mechanism of the forming machine. This process requires a large operating space and a long operating time, which affects production efficiency and cycle stability. Moreover, due to the different shapes and weights of paper rolls, manual handling may cause damage, affecting the service life of the paper rolls. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated cardboard box transfer clamp, including a guide rail embedded in the top surface of the site, and a transport vehicle slidably installed inside the guide rail; a drive assembly fixedly installed inside the guide rail, which drives the transport vehicle to move laterally; a clamping assembly fixedly installed on the upper part of the transport vehicle, wherein in use, the two clamping parts of the clamping assembly flip and form a V-shaped placement groove for clamping and placing paper rolls; and a lifting assembly fixedly installed on the upper part of the transport vehicle, wherein in use, the paper rolls horizontally on the clamping assembly are first transferred by the transport vehicle to the unwinding mechanism of the cardboard forming machine via the lifting assembly, and the lifting assembly raises the paper rolls to a horizontal position with the unwinding mechanism docking groove of the cardboard forming machine.

[0006] In at least some embodiments, the drive assembly includes a motor, which is fixedly mounted inside the guide rail, and a first wheel fixed at the output end of the motor and a second wheel rotatably mounted on the upper part of the guide rail are connected by a transmission belt.

[0007] In at least some embodiments, a first sprocket is fixedly connected to one side of the second wheel, and a second sprocket, which is rotatably installed inside the guide rail, is connected to the first sprocket via a chain.

[0008] In at least some embodiments, connecting arms are fixedly installed on both sides of the transport vehicle, and the upper part of the connecting arms is fixedly connected to the chain. When the motor starts, it synchronously drives the transport vehicle to perform a lateral movement.

[0009] In at least some embodiments, the transport vehicle includes a vehicle body with two wheels rotatably mounted on each side of the vehicle body, a second hydraulic rod fixedly mounted inside the vehicle body, and a clamping assembly including a first hydraulic rod rotatably mounted outside the vehicle body.

[0010] In at least some embodiments, the front of the guide rail is provided with a groove for connecting the hydraulic control system. The first transmission pipe and the second transmission pipe fixed at the front of the vehicle body are used to connect the hydraulic control system pipeline with the first hydraulic rod and the second hydraulic rod to realize the hydraulic control extension and retraction of the first hydraulic rod and the second hydraulic rod.

[0011] In at least some embodiments, the output end of the second hydraulic control lever extends through the vehicle body to the outside and is fixedly connected to a lifting plate. Four support columns are fixedly connected to the outside of the lifting plate, and support arms are rotatably installed on the upper parts of the four support columns respectively.

[0012] In at least some embodiments, the four support arms are grouped in pairs, and the clamping part of the clamping assembly is a clamping plate, with the clamping plate fixedly installed on the upper part of each group of support arms.

[0013] In at least some embodiments, four first support seats are fixedly connected to the outside of the vehicle body, and a first base is rotatably installed on the outside of each first support seat. A second base is fixedly connected to the output end of a first hydraulic rod fixed on the first base. The second base is fixedly connected to a second support seat fixed at the lower part of the clamping plate. In use, the second hydraulic cylinder controls the paper roll to rise and fall, and the first hydraulic rod moves synchronously to keep the included angle between the two clamping plates unchanged, performing a lifting and docking action.

[0014] In at least some embodiments, a cover plate is fixedly installed on the upper part of the guide rail, and a moving track for the clamping part of the clamping assembly is provided on the upper part of the cover plate; a placement groove is provided on one side of the cover plate, a frame plate is fixedly connected to the edge of the placement groove, and a strip plate is fixedly connected to the edge of the moving track for protection of the edge of the cover plate. When not in use, the placement groove is used to place the clamping part of the clamping assembly to keep the upper part of the cover plate flat.

[0015] Compared with the prior art, the advantages and positive effects of this invention are as follows: In operation, the drive component moves the transport vehicle laterally along the guide rail, allowing the paper roll to cross the production area and reach the target position directly. The clamping component on the upper part of the transport vehicle adopts a flip-type structure, with two clamping parts rotating in opposite directions to form a V-shaped placement groove, which can stably clamp paper rolls of different diameters and weights, effectively preventing shaking and slippage during transportation. After clamping, the transport vehicle moves along the guide rail to the unwinding mechanism above the cardboard forming machine. The lifting component is activated to smoothly lift the paper roll in the clamped state, keeping the paper roll and the unwinding mechanism's docking groove horizontally aligned. At this time, the operator can directly push the paper roll into the unwinding mechanism, achieving seamless connection and avoiding the heavy operation and precise alignment problems in traditional manual handling. The whole process reduces the reliance on forklifts, eliminates the safety risks of manually lifting heavy objects, and significantly improves docking accuracy and production efficiency. This fixture not only adapts to paper rolls of different specifications but can also flexibly cover multiple production stations through the guide rail layout, meeting the needs of continuous production and significantly improving the paper roll transfer method in carton manufacturing.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example, according to Figures 1-10 ,like Figure 1 As shown in the figure, an integrated cardboard box transfer fixture provided by an embodiment of the present invention includes a guide rail 1, which is embedded in the top surface of the site, and a transport vehicle 6, which is slidably installed inside the guide rail 1; a drive assembly 3, which is fixedly installed inside the guide rail 1 and drives the transport vehicle 6 to perform lateral movement; a clamping assembly 4, which is fixedly installed on the upper part of the transport vehicle 6. In use, the two clamping parts of the clamping assembly 4 are flipped and formed with V-shaped placement grooves for clamping and placing paper rolls; and a lifting assembly 7, which is fixedly installed on the upper part of the transport vehicle 6. In use, the paper rolls horizontally on the clamping assembly 4 are first transferred to the unwinding mechanism of the cardboard forming machine by the lifting assembly 7 via the transport vehicle 6. The lifting assembly 7 lifts the paper rolls so that they are in a horizontal state with the unwinding mechanism docking groove of the cardboard forming machine.

[0021] The aforementioned integrated cardboard box transfer fixture, through the coordinated operation of the top-embedded guide rail 1, transport vehicle 6, drive assembly 3, clamping assembly 4 and lifting assembly 7, achieves automated, safe and efficient transfer of paper rolls from the storage area to the unwinding mechanism of the cardboard forming machine; During operation, the drive component 3 drives the transport vehicle 6 to move laterally along the guide rail 1, enabling the paper roll to cross the production area and reach the target location directly. The clamping assembly 4 on the upper part of the transport vehicle 6 adopts a flip-type structure. The two clamping parts rotate in opposite directions to form a V-shaped placement groove, which can stably clamp paper rolls of different diameters and weights and effectively prevent shaking and slipping during transportation. After clamping is completed, the transport vehicle 6 moves along the guide rail 1 to the unwinding mechanism above the cardboard forming machine. The lifting component 7 is activated to smoothly lift the paper roll in the clamped state, so that the paper roll and the docking groove of the unwinding mechanism are horizontally aligned. At this point, the operator can directly push the paper roll into the unwinding mechanism to achieve a seamless connection, avoiding the heavy operation and precise alignment problems in the traditional manual handling process. The entire process reduces reliance on forklifts, eliminates the safety risks of manually lifting heavy objects, and significantly improves docking accuracy and production efficiency. This fixture not only adapts to paper rolls of different specifications, but also flexibly covers multiple production stations through the layout of guide rail 1, meeting the needs of continuous production and significantly improving the paper roll transfer method in carton manufacturing.

[0022] In this embodiment, the drive assembly 3 includes a motor 301, which is fixedly installed inside the guide rail 1. A first rotating wheel 302 fixed at the output end of the motor 301 and a second rotating wheel 304 rotatably installed on the upper part of the guide rail 1 are connected by a transmission belt 303. A first sprocket 305 is fixedly connected to one side of the second rotating wheel 304. A second sprocket 306 rotatably installed inside the guide rail 1 is connected to the first sprocket 305 by a chain 307. Connecting arms 8 are fixedly installed on both sides of the transport vehicle 6. The upper part of the connecting arms 8 is fixedly connected to the chain 307. When the motor 301 starts, it synchronously drives the transport vehicle 6 to perform a lateral movement.

[0023] The transport vehicle 6 moves smoothly laterally by being driven by motor 301.

[0024] Specifically, the motor 301 is fixedly installed inside the guide rail 1. After starting, the output end of the motor 301 drives the first rotating wheel 302 to rotate. The first rotating wheel 302 achieves synchronous transmission with the second rotating wheel 304 installed on the upper part of the guide rail 1 through the transmission belt 303.

[0025] A first sprocket 305 is fixedly installed on one side of the second rotating wheel 304. The sprocket is connected to a second sprocket 306 located inside the guide rail 1 via a chain 307, so that the rotational power of the motor 301 is transmitted sequentially through the transmission belt 303 and the sprocket-chain 307 structure.

[0026] The chain 307 runs along the guide rail 1 in a closed loop under the drive of the sprocket. The transport vehicle 6 is provided with connecting arms 8 on both sides, and the upper end of the connecting arms 8 is firmly fixed to the chain 307.

[0027] When the chain 307 moves in a straight line, the connecting arm 8 moves synchronously with the chain 307, thereby directly driving the transport vehicle 6 to achieve lateral displacement along the guide rail 1. During this process, the transmission belt 303 structure ensures flexible power transmission between the wheels, while the sprocket and chain 307 mechanism provides a stable and reliable linear drive effect, ensuring that the transport vehicle 6 runs smoothly and is accurately positioned during paper roll transfer, adapting to the needs of long-distance, multi-station automated conveying.

[0028] In this embodiment, the transport vehicle 6 includes a vehicle body 601, with two wheels 602 rotatably mounted on both sides of the vehicle body 601. A second hydraulic rod 701 is fixedly installed inside the vehicle body 601. The clamping assembly 4 includes a first hydraulic rod 403 rotatably mounted outside the vehicle body 601. A wire groove 5 for connecting the hydraulic control system is provided at the front of the guide rail 1. A first transmission pipe 603 and a second transmission pipe 604 fixed at the front of the vehicle body 601 are used to connect the hydraulic control system pipeline with the first hydraulic rod 403 and the second hydraulic rod 701, so as to realize the hydraulic control extension and retraction of the first hydraulic rod 403 and the second hydraulic rod 701.

[0029] The transport vehicle 6 is composed of a vehicle body 601. Two wheels 602 are rotatably mounted on both sides of the vehicle body 601 for smooth operation on the guide rail 1. A second hydraulic rod 701 is fixedly installed inside the vehicle body 601 for driving the lifting or pushing action of related mechanisms. The clamping assembly 4 includes a first hydraulic rod 403 rotatably mounted on the outside of the vehicle body 601 for driving the opening and closing of the clamping part. The front of the guide rail 1 is provided with a wire groove 5 for connecting the hydraulic control system. The first transmission pipe 603 and the second transmission pipe 604 fixed to the front of the vehicle body 601 are respectively used to connect the pipeline of the hydraulic control system to the first hydraulic rod 403 and the second hydraulic rod 701, thereby realizing the hydraulic control extension and retraction of the first hydraulic rod 403 and the second hydraulic rod 701. The extension and retraction of the first hydraulic rod 403 can cause the clamping part to clamp or release the paper roll, and the extension and retraction of the second hydraulic rod 701 can realize the lifting and positioning of relevant mechanisms on the transport vehicle 6. The whole process is centrally controlled by the hydraulic system, which improves the efficiency and safety of paper roll transfer and docking while ensuring coordinated and precise movements.

[0030] In this embodiment, the output end of the second hydraulic control rod extends through the vehicle body 601 to the outside and is fixedly connected to a lifting plate 702. Four support columns 703 are fixedly connected to the outside of the lifting plate 702. Support arms 704 are rotatably installed on the upper part of the four support columns 703. The four support arms 704 are in pairs. The clamping part of the clamping assembly 4 is a clamping plate 406. The clamping plate 406 is fixedly installed on the upper part of each pair of support arms 704. Four first support seats 401 are fixedly connected to the outside of the vehicle body 601. A first base 402 is rotatably installed on the outside of each first support seat 401. The output end of the first hydraulic rod 403 fixed on the first base 402 is fixedly connected to a second base 404. The second base 404 is fixedly connected to the second support seat 405 fixed at the lower part of the clamping plate 406. In use, the second hydraulic cylinder controls the lifting and lowering of the paper roll. The first hydraulic rod 403 moves synchronously to keep the included angle of the two clamping plates 406 unchanged and perform lifting and docking actions.

[0031] The paper roll is stably lifted and docked through the coordinated operation of the second hydraulic rod 701 and the first hydraulic rod 403. The output end of the second hydraulic rod 701 extends through the vehicle body 601 to the outside and is fixedly connected to the lifting plate 702. Four support columns 703 are fixedly connected to the outside of the lifting plate 702. Support arms 704 are rotatably installed on the upper part of the four support columns 703 respectively. The four support arms 704 are arranged in pairs. Each pair of support arms 704 has a clamping plate 406 fixedly installed on the upper part as the clamping part of the clamping assembly 4 for stabilizing the paper roll. Four first support seats 401 are fixedly connected to the outside of the vehicle body 601. A first base 402 is rotatably installed on the outside of each first support seat 401. A first hydraulic rod 403 is fixedly installed on the first base 402. A second base 404 is fixedly connected to the output end of the first hydraulic rod 403. The second base 404 is firmly connected to the second support seat 405 fixed at the lower part of the clamping plate 406. Through this connection structure, the clamping plate 406 can be synchronously adjusted to maintain a stable angle when the first hydraulic rod 403 extends and retracts. In use, the second hydraulic rod 701 is activated to drive the lifting plate 702 to rise and fall as a whole, achieving precise adjustment of the paper roll height. At the same time, the first hydraulic rod 403 extends and retracts synchronously according to the lifting state to maintain a constant angle between the two clamping plates 406, thereby avoiding loosening or excessive tightness of the clamping during the lifting process. This ensures that the paper roll is accurately positioned and stable when docking with the unwinding mechanism of the cardboard forming machine. Throughout the entire operation, the clamping force and lifting height are centrally controlled by the hydraulic system, which not only ensures the coordination and safety of the operation, but also improves the efficiency and accuracy of transfer and docking.

[0032] In this embodiment, a cover plate 2 is fixedly installed on the upper part of the guide rail 1. A moving track for the clamping part of the clamping component 4 is opened on the upper part of the cover plate 2. A placement groove 9 is opened on one side of the cover plate 2. A frame plate 10 is fixedly connected to the edge of the placement groove 9. A strip plate 11 is fixedly connected to the edge of the moving track for protection of the edge of the cover plate 2. When the cover plate 2 is not in use, the placement groove 9 is used to place the clamping part of the clamping component 4 to keep the upper part of the cover plate 2 flat.

[0033] A cover plate 2 is fixedly installed on the upper part of the guide rail 1. A special moving track is provided on the upper part of the cover plate 2 to guide the clamping part of the clamping assembly 4 to move smoothly along a predetermined path. A placement groove 9 is provided on one side of the cover plate 2. A frame plate 10 is fixedly connected to the edge of the placement groove 9 to enhance the structural strength and stability of the placement groove 9. Meanwhile, a strip plate 11 is fixedly connected to the edge of the moving track to effectively protect the edge of the cover plate 2 and prevent the clamping component 4 from colliding or being damaged during movement. The placement slot 9 serves as a temporary storage location for the clamping part when the clamping component 4 is not in use. It can effectively maintain the neat arrangement of the clamping component 4 and the flatness of the upper part of the cover plate 2, and avoid the clamping part being placed randomly, which would cause unevenness on the surface of the guide rail 1 or obstruct the movement of other mechanical parts. This ensures the long-term stable operation of the guide rail 1 and the clamping component 4 and the overall reliability of the mechanical system. This design not only optimizes the storage and movement space of the clamping component 4, but also improves the system's maintenance convenience and safety of use, and effectively supports the efficient scheduling and management of the clamping component 4 in the automated production line.

[0034] The working principle of this invention is as follows: During operation, the drive component 3 drives the transport vehicle 6 to move laterally along the guide rail 1, enabling the paper roll to cross the production area and reach the target position directly. The clamping component 4 on the upper part of the transport vehicle 6 adopts a flip-type structure, with two clamping parts rotating in opposite directions to form a V-shaped placement groove, which can stably clamp paper rolls of different diameters and weights, effectively preventing shaking and slippage during transportation. After clamping, the transport vehicle 6 moves along the guide rail 1 to the unwinding mechanism position above the cardboard forming machine. The lifting component 7 is activated to smoothly lift the paper roll in the clamped state, keeping the paper roll and the unwinding mechanism's docking groove horizontally aligned. At this time, the operator can directly push the paper roll into the unwinding mechanism to achieve seamless connection, avoiding the heavy operation and precise alignment problems in traditional manual handling.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
