Description

Technical Field

[0001] This utility model relates to the field of material packaging technology, specifically to a packaging bag opening and transfer mechanism. Background Technology

[0002] Packaging bags are widely used in the packaging of bulk materials such as grains, fertilizers, feed, building materials, and chemical raw materials. For example, the most commonly used woven bags are crucial preliminary steps in the packaging of bulk materials such as powders and granules. Accurately opening the bag opening and fitting it onto the material hopper discharge port is a key step to ensure smooth material filling, prevent dust leakage, and improve packaging efficiency.

[0003] Currently, this step still largely relies on manual operation. Workers need to manually open the bag opening, align it, and lift it into the hopper outlet. This is not only labor-intensive and inefficient, but also poses occupational health and safety hazards such as dust exposure. Therefore, there is an urgent need to develop an efficient, reliable, and adaptable automated bag opening and transfer mechanism to achieve integrated and intelligent operation of bag opening, transfer, and connection to the hopper outlet. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a packaging bag opening and transfer mechanism.

[0005] This utility model is achieved through the following technical solution: a packaging bag opening and transfer mechanism is provided, including a support platform and an upper pneumatic suction cup and a lower pneumatic suction cup located on the upper and lower sides of the support platform respectively. The support platform has a through hole for the pneumatic suction cup to pass through. It also includes an upper suction cup lifting mechanism for driving the upper pneumatic suction cup to move up and down and a lower suction cup lifting mechanism for driving the lower pneumatic suction cup to move up and down. It also includes a rotating shaft located on the support platform, a transfer motor for driving the rotating shaft to rotate, two opening arms hinged on the rotating shaft, and an opening cylinder for driving the two opening arms to open and close.

[0006] In this design, the upper and lower pneumatic suction cups are respectively attached to the upper and lower sides of the bag opening. The bag opening is opened by the reverse movement of the upper and lower cylinders. The transfer motor drives the rotating shaft to rotate, causing the end of the opening support arm to insert into the bag opening. The opening support cylinder drives the two opening support arms to swing in opposite directions, and the two support plates are respectively attached to the two ends of the opening to open the bag opening. Then, the transfer motor drives the rotating shaft to reset, causing the opening support arms to swing upward, thereby adjusting the packaging bag to a position where the bag opening faces upward.

[0007] As an optimization, the upper suction cup lifting mechanism includes an upper cylinder and an upper suction cup mounting plate fixed to the telescopic shaft of the upper cylinder. Two upper pneumatic suction cups are mounted on the upper suction cup mounting plate. In this design, the upper cylinder drives the lifting and lowering of the upper pneumatic suction cups, and the use of two upper pneumatic suction cups allows for a more thorough opening of the bag.

[0008] As an optimization, the lower suction cup lifting mechanism includes a lower cylinder and a lower suction cup mounting plate fixed to the telescopic shaft of the lower cylinder. Two lower pneumatic suction cups are mounted on the mounting plate. In this design, the lower cylinder drives the lifting and lowering of the lower pneumatic suction cups, and the use of two lower pneumatic suction cups allows for a more thorough opening of the bag.

[0009] As an optimization, a support plate is fixedly connected to one end of the support arm near the support platform. The support plate in this design facilitates insertion into the bag opening, thus opening the bag.

[0010] As an optimization, the two ends of the support cylinder are hinged to the two support arms respectively. Thus, the opening and closing are achieved by the opposite swing of the two support arms through one support cylinder.

[0011] As an optimization, a synchronizing link connects the two support arms. The two ends of the synchronizing link are hinged to the two support arms respectively, and are located on opposite sides of the rotating shaft. In this design, the two ends of the synchronizing link are located on opposite sides of the rotating shaft, thus achieving synchronous swinging of the two support arms.

[0012] As an optimization, the rotating shaft is rotatably connected to the rotating shaft bearing housing, and the transfer motor is fixedly connected to the transfer motor reducer. In this solution, the rotating shaft bearing housing enables the installation of the rotating shaft, and the transfer motor drives the rotating shaft to rotate after being reduced in speed by the transfer motor reducer.

[0013] As an optimization, the system also includes upper pressure rollers and support rollers located on the upper and lower sides of the packaging bag, an upper pressure roller drive mechanism that drives the upper pressure rollers to press against the support rollers, and a support roller motor that drives the support rollers to rotate. In this solution, during the forward conveying of the packaging bag, the upper pressure rollers press the packaging bag against the lower support rollers, and the support roller motor drives the support rollers to rotate, thereby creating pleats at the bag opening to facilitate opening the bag.

[0014] As an optimization, a baffle and a baffle cylinder for driving the baffle to rise and fall are installed in front of the support platform. When the packaging bag is conveyed forward on the support platform, the baffle limits the front end of the packaging bag.

[0015] The beneficial effects of this utility model are as follows: The packaging bag opening and transfer mechanism of this utility model realizes the opening of the bag through the upper and lower suction cups, and realizes the opening and transfer of the bag through two opening arms. Thus, the entire process of packaging bag opening from opening to precise fitting of material bin outlet is automated, which significantly improves packaging efficiency, reduces labor costs and labor intensity, and improves the safety of the working environment.

[0016] With its ingenious overall structural design and optimized workflow, it not only simplifies operation steps and increases bagging speed, enabling seamless integration into high-speed automated packaging production lines, but also ensures stable operation and convenient maintenance, significantly improving the automation level and overall efficiency of packaging operations.

Detailed Implementation

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0028] like Figures 1-8As shown, the present invention provides a packaging bag opening and transfer mechanism, including a support platform 7 and an upper pneumatic suction cup 10 and a lower pneumatic suction cup 13 located on the upper and lower sides of the support platform 7 respectively. The support platform 7 is a horizontal flat plate structure, which is set at the end of the conveyor belt of the feeding mechanism, and the height of the support platform 7 is flush with the upper surface of the conveyor belt. Therefore, when a single packaging bag is conveyed forward, the front end of the bag opening can be moved onto the support platform 7.

[0029] It also includes upper pressure rollers 18 and support rollers 19 located on the upper and lower sides of the packaging bag. Two upper pressure rollers 18 and two support rollers 19 are provided. The support rollers 19 are positioned below the support platform 7, with their upper ends slightly higher than the upper surface of the support platform 7. A rectangular opening is provided on the support platform 7 to allow the upper ends of the support rollers 19 to protrude. A support roller motor is installed below the support platform 7 to drive the rotation of the support rollers 19.

[0030] It also includes an upper pressure wheel drive mechanism that drives the upper pressure wheel 18 to press against the support wheel 19, such as Figure 4 As shown, the upper pressure roller 18 is mounted on a four-bar linkage 20. This four-bar linkage is a quadrilateral structure formed by four links hinged at their ends. The upper pressure roller 18 is pivotally connected to a lower link. The upper link is driven to swing up and down by the upper pressure roller cylinder 21, thus achieving the up-and-down movement of the upper pressure roller 18. The upper end of the upper pressure roller cylinder 21 is hinged to a fixed four-bar mounting bracket 22, and the lower end is hinged to the link. The extension of the upper pressure roller cylinder 21 causes the upper pressure roller 18 to move downwards. Figure 5 The image shows a side view of the upper pressure roller 18 pressing against the support roller 19. The rotation of the support roller 19 causes the packaging bag to move forward, preventing the packaging bag from getting stuck on the support platform 7.

[0031] The support platform 7 is equipped with a baffle 16 and a baffle cylinder 17 for driving the baffle 16 to rise and fall. The baffle cylinder 17 is fixedly installed with its telescopic shaft facing upward. The baffle 16 is vertically fixed to the telescopic shaft of the baffle cylinder 17. When the packaging bag is conveyed forward, the baffle 16 limits the packaging bag.

[0032] The support platform 7 has a through hole for the lower pneumatic suction cup 13 to pass through, so the lower pneumatic suction cup 13 can fit against the lower end face of the bag opening and be used to hold the lower packaging bag.

[0033] It also includes an upper suction cup lifting mechanism that drives the upper pneumatic suction cup 10 to move up and down, and a lower suction cup lifting mechanism that drives the lower pneumatic suction cup 13 to move up and down.

[0034] The upper suction cup lifting mechanism includes an upper cylinder 8 and an upper suction cup mounting plate 9 fixedly connected to the telescopic shaft of the upper cylinder 8. The upper cylinder 8 is fixedly set with the telescopic shaft facing downward. The upper suction cup mounting plate 9 is equipped with two upper pneumatic suction cups 10. The upper suction cup mounting plate 9 has a hollow structure and is connected to both upper pneumatic suction cups 10. The pneumatic pipeline is connected to the inside of the upper suction cup mounting plate 9, so the adsorption operation of the two upper pneumatic suction cups 10 can be realized simultaneously.

[0035] The lower suction cup lifting mechanism includes a lower cylinder 11 and a lower suction cup mounting plate 12 fixed to the telescopic shaft of the lower cylinder 11. The lower cylinder 11 is located below the support platform 7, with its telescopic shaft facing upwards. Two lower pneumatic suction cups 13 are mounted on the lower suction cup mounting plate 12. The lower suction cup mounting plate 12 has a hollow structure and is connected to both lower pneumatic suction cups 13. Pneumatic pipelines are connected to the interior of the lower suction cup mounting plate 12, thus allowing simultaneous suction operation of both lower pneumatic suction cups 13. When the packaging bag moves onto the support platform 7, the lower cylinder 11 moves the lower pneumatic suction cups 13 to the lower position, thus not affecting the normal movement of the packaging bag.

[0036] It also includes a rotating shaft 1 located on the support platform 7 and a transfer motor 15 that drives the rotating shaft 1 to rotate. The rotating shaft 1 is rotatably connected to the rotating shaft bearing seat 6, and the transfer motor is fixed to the transfer motor reducer 14. After the transfer motor is reduced in speed by the transfer motor reducer 14, it drives the rotating shaft 1 to rotate. The rotating shaft 1 is horizontally set and its length direction is perpendicular to the orientation of the bag opening.

[0037] It also includes two support arms 2 hinged to the rotating shaft 1 and a support cylinder 4 for driving the two support arms 2 to open and close. The two support arms 2 are arranged along the length of the rotating shaft 1, and the hinge axis of the support arms 2 and the rotating shaft 1 is perpendicular to the axis of the rotating shaft 1. The rotation of the rotating shaft 1 can drive the support arms 2 to swing between a horizontal state and a vertical state.

[0038] The two support arms 2 can be driven to swing in opposite directions by the support cylinder 4, thereby realizing the opening and closing operation of the two support arms 2. The two ends of the support cylinder 4 are respectively hinged to the two support arms 2, so that the two support arms 2 can swing in opposite directions by one support cylinder 4. In order to achieve synchronous swinging of the two support arms 2, such as Figure 2 As shown, a synchronizing rod 5 connects the two support arms 2. The two ends of the synchronizing rod 5 are hinged to the two support arms 2 respectively, and the two ends of the synchronizing rod 5 are located on opposite sides of the rotating shaft 1. Figure 2 As shown, when Figure 2 When the left support arm 2 swings to the right, it will drive the synchronous connecting rod 5 to move to the right, thereby driving the upper end of the right support arm 2 to move to the right, which in turn drives the main body of the right support arm 2 to swing to the left.

[0039] A support plate 3 is fixedly connected to one end of the support arm 2 near the support platform 7. In this embodiment, the support plate 3 and the support arm 2 are integrally formed. The support plate 3 is located on the side of the support arm 2 closer to the bag opening, so that it can be inserted into the bag opening. The two support plates 3 are in a parallel or nearly parallel state, thus expanding the bag opening.

[0040] How to use this utility model:

[0041] Initial state as Figure 4 As shown, the packaging bag is conveyed forward by the conveyor belt of the feeding mechanism. When the front end of the packaging bag covers the support roller 19, the upper pressure roller 18 moves downward, pressing the packaging bag firmly onto the support roller 19. The rotation of the support roller 19 drives the packaging bag forward. At this time, the baffle 16 is in the raised state, as shown in the diagram. Figure 5 As shown.

[0042] After the packaging bag is in place, the upper pressure roller 18 returns to its original position, the upper cylinder 8 drives the upper pneumatic suction cup 10 to descend above the bag opening, and the lower cylinder 11 drives the lower pneumatic suction cup 13 to rise below the bag opening. The state at this point is as follows: Figure 6 As shown.

[0043] The upper pneumatic suction cup 10 and the lower pneumatic suction cup 13 respectively adhere to both sides of the bag opening. The upper cylinder 8 and the lower cylinder 11 reset, thus opening the bag opening. The transfer motor drives the rotating shaft 1 to rotate, causing the two support arms 2 to swing downwards. This allows the support plates 3 at the ends of the support arms 2 to insert into the bag opening. The extension of the support cylinder 4 causes the two support arms 2 to swing in the opposite direction, with the two support plates 3 respectively fitting against both ends of the opening, thus opening the bag opening. The baffle 16 then descends, and the bag is in the following state: Figure 7 As shown.

[0044] Then the transfer motor drives the rotating shaft 1 to reset, causing the support arm 2 to swing upward, thereby adjusting the packaging bag to a position where the bag opening faces upward. At this time, the state is as follows: Figure 8 As shown.
