Description
Technical Field
[0001] This utility model belongs to the technical field of packaging production line equipment, and specifically relates to a packaging box lid gripping and pressing mechanism. Background Technology
[0002] Currently, automated packaging lines are widely used in product packaging processes across numerous industries, including food, pharmaceuticals, cosmetics, and electronics. Among these processes, the automatic closing and pressing of packaging boxes is a crucial step, directly impacting product packaging quality, appearance, and production efficiency. Existing automated equipment for these processes typically uses pneumatically driven or servo-motor-driven robotic arms in conjunction with suction cups or grippers to perform the grasping and pressing actions. However, these existing devices generally suffer from the following drawbacks: First, during the box lid transfer process, traditional rigid mechanisms struggle to ensure the lid maintains a stable horizontal position. The lid often deflects or even flips along with the rigid mechanism, causing misalignment with the box body upon reaching the closing station, resulting in problems such as lid jamming, incomplete closing, or damage to the packaging. Second, to complete the complex actions from grasping to pressing, existing equipment generally employs multiple drive systems to control the grasping, rotating, and pressing actions separately. This leads to a complex overall equipment structure, large space occupation, high manufacturing costs, and high precision requirements for coordinated control, resulting in inconvenient and costly debugging and maintenance, hindering widespread adoption.
[0003] Therefore, it is necessary to design a packaging box lid gripping and pressing mechanism that can at least solve some of the above problems and defects. Summary of the Invention
[0004] To solve the above technical problems, this utility model proposes a box lid gripping and pressing mechanism, which can realize the gripping and transferring of box lids and the closing and pressing process. The pulley structure ensures that the box lid is in a horizontal state during the transfer process, which improves the stability of the box lid transfer process and the convenience of the subsequent closing and pressing operation. The structure is compact and the movement is stable, which simplifies the structure of the equipment, reduces manufacturing and maintenance costs, and facilitates its widespread use.
[0005] The technical solution of this utility model is: This utility model proposes a packaging box lid gripping and pressing mechanism, including a reciprocating drive motor, a transfer rocker arm vertically fixed on the output shaft of the reciprocating drive motor, a horizontal support shaft vertically movably disposed at the end of the transfer rocker arm, and a transfer frame fixed on the horizontal support shaft. The horizontal support shaft is provided with a driving pulley fixedly connected to it. The driving pulley is coaxially arranged with the horizontal support shaft and is arranged close to the transfer rocker arm. The reciprocating drive motor is provided with a driven pulley movably sleeved on its output shaft. The driving pulley and the driven pulley are connected by a synchronous tension belt.
[0006] Preferably, the outer diameter of the driven pulley is larger than the outer diameter of the driving pulley, both the driving pulley and the driven pulley are toothed pulleys, and the synchronous tensioning belt is a toothed belt.
[0007] Preferably, the transfer frame includes a lifting cylinder fixedly disposed at the end of the horizontal support shaft, and a main frame fixedly disposed at the end of the piston rod of the lifting cylinder. The main frame is arranged horizontally and is arranged parallel to and spaced apart from the horizontal support shaft.
[0008] Preferably, the bottom of the main frame is provided with a plurality of partitions spaced apart along its length, and the adjacent partitions form an accommodating space for placing the box lid.
[0009] Preferably, the main frame is provided with a plurality of vacuum suction cups spaced apart along its length, the vacuum suction cups being located within the accommodating space and corresponding one-to-one with the plurality of accommodating spaces.
[0010] Preferably, the main frame is further provided with a plurality of vacuum pipes spaced apart along its length, the vacuum pipes passing through the main frame and connected to the vacuum suction cup.
[0011] This utility model has the following advantages and effects compared with the prior art: (1) A transfer rocker arm fixedly connected to a reciprocating drive motor is adopted. The reciprocating motion of the reciprocating drive motor drives the transfer rocker arm to swing back and forth to realize the transfer of the box cover position and transfer it from the box cover transport line to the box body transport line. The structure is simple and easy to use, reducing production and manufacturing costs as well as subsequent maintenance costs. (2) A horizontal support shaft is vertically and movable at the end of the transfer rocker arm, and the horizontal support shaft is rotatably connected to the transfer rocker arm. This allows the horizontal support shaft to rotate at a certain angle as it swings with the transfer rocker arm, so as to keep the transfer frame and the box lid being gripped in a horizontal state. This adjusts and controls the posture and trajectory of the transfer frame and the box lid during the transfer process, which is beneficial for the subsequent capping and closing process. (3) The synchronous rotation of the horizontal support shaft during the swing process is achieved by using a combination of active pulley, driven pulley and synchronous tension belt structure. The overall structure is simple and compact, and there is no need to set up an independent box cover flip adjustment control mechanism, which reduces the overall manufacturing and maintenance costs of the equipment.

[0014] To enable those skilled in the art to better understand this utility model, it will now be further described in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this utility model.
[0015] Example: like Figures 1-5 As shown, this utility model provides a packaging box lid gripping and pressing mechanism, specifically including a reciprocating drive motor 1, a transfer rocker arm 2 vertically fixed on the output shaft of the reciprocating drive motor 1, a horizontal support shaft 3 vertically movably mounted at the end of the transfer rocker arm 2, and a transfer frame 4 fixedly mounted on the horizontal support shaft 3. The transfer rocker arm 2 is vertically fixedly connected to the output shaft of the reciprocating drive motor 1, so that the transfer rocker arm 2 reciprocates under the driving action of the reciprocating drive motor 1, thereby driving the box lid gripped on the transfer frame 4 to move and transfer, for example, taking out the packaging box lid 8 from the box lid conveying station and transferring it to the packaging box body 9 conveying station, so as to facilitate the subsequent lid closing and pressing operation. The horizontal support shaft 3 is rotatably mounted at the end of the transfer rocker arm 2 and is parallel to the output shaft of the reciprocating drive motor 1, so that by adjusting the rotation angle of the horizontal support shaft 3, the transfer frame 4 fixedly connected to it remains in a horizontal state during the reciprocating movement of the transfer rocker arm 2. Figure 2 and Figure 3 As shown, the transfer frame 4 will not deflect or even flip, thus ensuring the stability of the lid transfer process and the convenience of lid removal and closing operations. Further reference Figure 1As shown, the horizontal support shaft 3 is equipped with a driving pulley 5 fixedly connected to it. The driving pulley 5 is coaxially arranged with the horizontal support shaft 3 and is positioned close to the transfer rocker arm 2. The reciprocating drive motor 1 is equipped with a driven pulley 6 movably sleeved at the end of its output shaft. The driven pulley 6 is rotatably sleeved on the outer circumference of the end of the output shaft of the reciprocating drive motor 1. The driving pulley 5 and the driven pulley 6 are synchronously driven by a synchronous tension belt 7 connected to both, so that when the reciprocating drive motor 1 drives the transfer rocker arm 2 to reciprocate, the horizontal support shaft 3 follows the reciprocating swing of the transfer rocker arm 2. At the same time, under the tension of the synchronous tension belt 7, the driving pulley 5 rotates, thereby driving the horizontal support shaft 3 to rotate to ensure that the transfer frame 4 remains horizontal. The driven pulley 6 rotates under the action of the synchronous tension belt 7. It should be noted that the driven pulley 6 can be movably sleeved on the output shaft of the reciprocating motor through a bearing to ensure that the rotation of the output shaft of the reciprocating drive motor 1 does not affect the driven pulley 6.
[0016] like Figure 2 As shown, furthermore, the outer diameter of the driven pulley 6 is larger than the outer diameter of the driving pulley 5. Both the driving pulley 5 and the driven pulley 6 are toothed pulleys, and the synchronous tension belt 7 is also a toothed belt. This improves the stability of the driving pulley 5 and the transverse support shaft 3, preventing the transverse support shaft 3 from deflecting on its own. That is, the driven pulley 6 rotates only if the transfer rocker arm 2 swings. When the transfer rocker arm 2 does not swing, the transverse support shaft 3 will not rotate and will be in a stable equilibrium state. Specifically, in this embodiment, the outer diameter of the driven pulley 6 is twice the outer diameter of the driving pulley 5.
[0017] refer to Figure 1 As shown, the transfer frame 4 specifically includes a lifting cylinder 41 fixedly installed at the end of the horizontal support shaft 3, and a main frame 42 fixedly installed at the end of the piston rod of the lifting cylinder 41. The main frame 42 is horizontally arranged and parallel to the horizontal support shaft 3 at intervals. Specifically, the main frame 42 is located below the horizontal support shaft 3. The bottom of the main frame 42 is provided with several partitions 43 spaced apart along its length. These partitions 43 are arranged parallel to each other, and adjacent partitions 43 form a space for placing the box lid. The distance between adjacent partitions 43 is not less than the length or width of the box lid 8. Specifically, in this embodiment, the distance between adjacent partitions 43 is greater than the length of the box lid 8. Figure 4 As shown.
[0018] Furthermore, the main frame 42 is also equipped with several vacuum suction cups 44 and vacuum pipes 45 arranged at intervals along its length. The vacuum suction cups 44 and vacuum pipes 45 are arranged one-to-one with the accommodating space. The vacuum pipes 45 pass through the main frame 42 and are connected to the vacuum suction cups 44 located in the accommodating space, so as to realize the suction and release of the lid by connecting to an external air source device. It should be noted that since the air source device connecting the lifting cylinder 41 and the vacuum suction cup 44 is a mature existing technology in this field, it is not shown in the figure, and the specific structure and principle will not be described in detail here. In addition, the air source device connected to the lifting cylinder 41 and the air source device connected to the vacuum suction cup 44 can be a single device, connected and controlled by different pipelines (such as multi-way pipelines), or they can be two independent air source devices.
[0019] In the specific work process, the initial state is referenced. Figure 2 As shown, the reciprocating drive motor 1 does not rotate. The lifting cylinder 41, driven by the air source equipment, moves the main frame 42 downwards, locking it against the lid of the packaging box lid 8 conveyor station located directly below it. At this time, the air source equipment, connected to the vacuum suction cup 44 via the vacuum pipe 45, operates, creating a vacuum between the vacuum pipe 45 and the vacuum suction cup 44 so that the vacuum suction cup 44 can hold the lid. (See reference for details.) Figure 4 As shown, the reciprocating drive motor 1 then operates, driving the transfer rocker arm 2 and the horizontal support shaft 3 to swing and transfer the box lid. During the swinging motion of the horizontal support shaft 3 following the transfer rocker arm 2, the synchronous tension belt 7, pulled by the horizontal support shaft 3, drives the drive pulley 5 to rotate, thereby rotating the horizontal support shaft 3 at a certain angle to ensure that the main frame 42 and the box lid are in a horizontal state. When the transfer rocker arm 2 swings to the designated position, the reciprocating drive motor 1 stops rotating. At this time, the lifting cylinder 41 operates, pressing the box lid at the bottom of the main frame 42 downwards onto the opening of the packaging box 9 directly below. (See reference for details.) Figure 5 As shown, the air source device connected to the vacuum suction cup 44 then works to release the vacuum suction state, causing the vacuum suction cup 44 to detach from the box lid. The lifting cylinder 41 drives the main frame 42 to move upward and detach from the packaging box. The reciprocating drive motor 1 works to drive the transfer rocker arm 2 to reset. Repeating the above steps can complete the continuous gripping and pressing of the box lid.
[0020] In summary, the packaging box lid gripping and pressing mechanism provided by this utility model can realize the gripping and transferring of the box lid as well as the closing and pressing process. Moreover, the pulley structure ensures that the box lid is in a horizontal state during the transfer process, which improves the stability of the box lid transfer process and the convenience of the subsequent closing and pressing operation.
[0021] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
