Detailed implementation manners

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0027] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments. The present utility model provides the following embodiments.

[0029] By Figure 1 、 Figure 2 and Figure 3As shown in the figure, a bag box assembly for a packaging machine includes a chassis 1, a placement table 2, a protection plate 3, and side protection plates 6. The protection plates 3 are symmetrically arranged on both sides of the chassis 1. The placement table 2 is slidably installed at the top of the chassis 1, and the side protection plates 6 are fixedly installed at the ends of the chassis 1. A lifting mechanism 4 is arranged on the surface of the chassis 1. The lifting mechanism 4 includes a driving component 41, a matching arm 42, a swinging arm 43, and a rotating rod 44. The driving component 41 is fixedly installed on the upper surface of the chassis 1. The swinging arm 43 is rotatably installed on the side of the driving component 41. The matching arm 42 is arranged on the side of the swinging arm 43 and is mirror - set with the swinging arm 43. A rotating rod 44 is rotatably installed between the matching arm 42 and the swinging arm 43. During use, by installing the device at the target position, when the bag - loading arm needs to grab the packaging bag, the operation of the driving component 41 can change the overall angle of the swinging arm 43. The swinging arm 43 moves toward the side close to the side protection plate 6. Because the overall length of the swinging arm 43 is fixed and with the cooperation of the rotating rod 44 itself, the other end of the swinging arm 43 will move upward. During the movement of the swinging arm 43, the distance between the chassis 1 and the placement table 2 gradually expands, and the placement table 2 will move directly upward, facilitating the bag - loading arm to grab the packaging bag.

[0030] As shown by the attached Figure 3 As shown in the figure, in this embodiment, the lifting mechanism 4 further includes a rotating shaft 45 and a sliding block 46. The rotating shafts 45 are respectively rotatably installed at the ends of the matching arm 42 and the swinging arm 43, and the rotating shafts 45 are located at the end close to the side protection plate 6. The rotating shafts 45 are fixedly connected to both the chassis 1 and the placement table 2. The sliding block 46 is rotatably installed at the other ends of the matching arm 42 and the swinging arm 43, and the sliding block 46 is located at the end far from the side protection plate 6. The sliding block 46 is slidably connected to the inner walls of the placement table 2 and the chassis 1. During use, through the installation and use of the rotating shaft 45 and the sliding block 46, it can be ensured that when the angles of the matching arm 42 and the swinging arm 43 change, the rotating shaft 45 itself will automatically rotate, facilitating the auxiliary tilting of the matching arm 42 and the swinging arm 43. Moreover, the installation of the sliding block 46 can limit the movement trajectory of the other ends of the matching arm 42 and the swinging arm 43, enabling them to always slide closely along the inner walls of the chassis 1 and the placement table 2, allowing the placement table 2 to perform vertical lifting movement above the chassis 1.

[0031] As shown by the attached Figure 4As shown in the figure, in this embodiment, the driving assembly 41 further includes a driving motor 411, a first lead screw 412, a moving end 413, and a connecting arm 414.

During use, driven by the driving motor 411, the first lead screw 412 rotates itself. The moving end 413 will closely adhere to the outside of the first lead screw 412, and the position of the moving end 413 itself is adjusted through the thread outside the first lead screw 412. When the moving end 413 moves, the connecting arm 414 will drive the other side of the swing arm 43 to move, thereby controlling the inclination of the overall angle of the swing arm 43.

[0032] As shown in the attached Figure 5 As shown in the figure, in this embodiment, it further includes a moving mechanism 5. The moving mechanism 5 is used to control the left and right movement of the chassis 1 and the upper components in real time. The moving mechanism 5 includes a moving frame 51. The moving frames 51 are symmetrically and fixedly installed at the bottom end of the chassis 1. The moving frame 51 is used to drive the chassis 1 to move synchronously. During use, through the movement of the moving frame 51, the chassis 1 and the upper components can be driven to move synchronously, which is convenient for the bagging arm to grasp packaging bags of different specifications.

[0033] As shown in the attached Figure 5 As shown in the figure, in this embodiment, the moving mechanism 5 further includes a sleeve 52, a second lead screw 53, and a guide rod 54. The sleeve 52 is fixedly installed between the moving frames 51. The second lead screw 53 is threadedly installed inside the sleeve 52. The guide rod 54 is arranged on the side of the second lead screw 53, and the guide rod 54 is parallel to the position of the second lead screw 53. The guide rod 54 is slidably connected to the moving frame 51. During use, the second lead screw 53 rotates itself. At this time, the moving frame 51 will automatically move along the outer wall of the second lead screw 53. The installation and use of the guide rod 54 ensure that the moving track of the moving frame 51 is in a horizontal state, so that the moving frame 51 can stably drive the chassis 1 and the upper components to move horizontally left and right.

[0034] As shown in the attached Figure 5As shown in the figure, in this embodiment, the moving mechanism 5 further includes a rotating assembly 55, a mounting flange 56 and a fixing block 57.

In use, through the use of the fixing flange 552, the second lead screw 53 can be integrally installed between the protective plates 3. With the cooperation of the transmission rod 551, the rotating handle 553 can stably drive the transmission rod 551 and the second lead screw 53 to rotate, ensuring the stability of the component operation.

[0036] As shown in the attached Figure 1 As shown in the figure, in this embodiment, the side guard plate 6 includes a bag-taking baffle 61 and a bag-taking opening 62. The bag-taking baffle 61 is fixedly installed at the end of the chassis 1. A bag-taking opening 62 is formed at the upper end of the bag-taking baffle 61. In use, through the installation of the bag-taking baffle 61, the packaging bags on the upper surface of the placing table 2 can be calibrated, and the height of the placing table 2 can be quickly adjusted according to the overall thickness of the packaging bags. The opening of the bag-taking opening 62 facilitates the movement and grasping of the bag-loading arm, strengthening the stability of the equipment during use.
