[0029] Reference Figures 1 to 5 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a packaging bag gripping device, including a frame 1 and a conveyor belt 2, the frame 1 is provided with a placement groove 11 for placing packaging bags, the conveyor belt 2 is provided on one side of the placement groove 11, the frame 1 is provided with a drive mechanism 3, a mounting base 4, a square moving mechanism 5, a gripping mechanism 6 and a guiding mechanism 7, the drive mechanism 3, the square moving mechanism 5, the gripping mechanism 6 and the guiding mechanism 7 are all mounted on the mounting base 4;

[0030] Drive mechanism 3 is used to drive the square moving mechanism 5 to move;

[0031] The gripping mechanism 6 is mounted on the square moving mechanism 5 and moves along a square path with the square moving mechanism 5.

[0032] One end of the gripping mechanism 6 is connected to the guiding mechanism 7, which is used to guide the movement of the gripping mechanism 6.

[0033] The design of this utility model utilizes the cooperation of the square moving mechanism 5 and the driving mechanism 3 to enable the gripping mechanism to move in a square path, thereby gripping the packaging bag in the placement slot 11 from high to low. The gripping height can be controlled according to the operation of the driving mechanism 3, which has the feature of flexible gripping.

[0034] This invention is further configured such that the drive mechanism 3 includes a drive motor 31 and a right-angle reducer 32, with the conveying end of the drive motor 31 connected to the right-angle reducer 32. This design, through the forward and reverse rotation of the drive motor 31, enables the gripping mechanism 6 to move back and forth between material point A and conveying point B.

[0035] The gripping height can be controlled based on the rotation of the drive motor 31.

[0036] This invention is further configured such that: the gripping mechanism 6 includes a gripping rod 61 and a gripping head 62, and the gripping head 62 is provided with multiple sets of suction cups 63, each of which is connected to a vacuum generator. This structure is designed to generate negative pressure on the adsorption surface (such as the suction cups 63) using a vacuum pump or vacuum generator, thereby using atmospheric pressure to firmly press the packaging bag onto the suction cups 63, achieving non-destructive gripping.

[0037] The present invention is further configured such that: the gripping rod 61 includes a mounting rod 64 and an adjusting rod 65, the mounting rod 64 is provided with a sliding groove and a positioning hole, the adjusting rod 65 is provided with multiple sets of locking holes along its length direction, the adjusting rod 65 is slidably connected in the sliding groove, and the positioning hole and the locking hole are fixed by bolt limit.

[0038] The design of this structure allows for changing the height of the gripping head 62 by altering the length of the gripping rod 61, thus meeting the installation and gripping requirements of various environments.

[0039] The present invention is further configured such that: a limiting block 41 is detachably installed on the mounting base 4, and two sets of the limiting block 41 are provided, which are respectively located on both sides of the square moving mechanism 5;

[0040] The upper end of the gripping lever 61 is T-shaped. This structure is designed as follows: Figure 2 As shown, limiting blocks 41 are respectively provided on both sides of the mounting base 4. The limiting blocks 41 abut against the upper end of the gripping rod 61, thereby limiting the movement stroke of the gripping rod 61 and avoiding excessive pressure of the gripping head 62 on the packaging bag and conveyor belt 2.

[0041] This utility model is further configured such that: the guiding mechanism 7 includes a guide rail 71 and a guide seat 72, the guide rail 71 extends along the length direction of the mounting base 4, the guide seat 72 is slidably connected to the guide rail 71, and one end of the gripping rod 61 is slidably connected to the guide seat 72. This structure design assists in the left and right movement of the gripping rod 61, and, in conjunction with the guide groove 42, ensures stable movement of the gripping rod 61.

[0042] The present invention is further configured such that: the square moving mechanism 5 includes a triangular disk 51, a rotating rod 52 and a rotating wheel 53, the rotating rod 52 is connected to the driving mechanism 3, and the triangular disk 51 is connected to the rotating rod 52 through the rotating wheel 53;

[0043] The triangular disk 51 is provided with a guide post, and the mounting base 4 is provided with a square guide groove 42. The guide post is slidably connected in the guide groove 42.

[0044] In this structure, the rotating rod 52 is connected to the rotating wheel 53. When the rotating rod 52 rotates, the rotating wheel 53 rotates accordingly. To meet the square path movement requirement of the gripping rod 61, the rotating rod 52 is connected to the non-central area of ​​the rotating wheel 53. When the rotating rod 52 rotates, the rotating wheel 53 rotates around the rotating rod 52, which in turn drives the triangular disk 51 to rotate. Since the guide post is located within the guide groove 42, the triple cooperation of the guide post, the motion trajectory, and the guide mechanism 7 allows the gripping rod 61 to move along a square path. Alternatively, as... Figure 5 The structural diagram shown is based on the same principle.

[0045] The utility model is further configured such that: the limiting block 41 includes a first limiting block and a second limiting block, the second limiting block being disposed above the conveyor belt 2, and a counting sensor being disposed at the upper end of the second limiting block. With this structure, when the second limiting block abuts against the gripping rod 61, the counting sensor is triggered, thereby realizing the counting operation.

[0046] This invention is further configured such that the gripping head 62 is detachably connected to the lower end of the gripping rod 61. This design allows for the replacement of the gripping head 62, thus meeting the requirements for negative pressure gripping operations on different packaging bags.

[0047] The present invention is further configured such that: a window is provided on the frame 1, and the drive motor 31 and the right-angle reducer 32 are both located inside the window.

[0048] The design of this structure facilitates the placement of the drive motor 31 and the right-angle reducer 32, and the drive motor 31 can abut against the frame 1, improving the stability of the installation.
