[0004] However, there is a problem with the above technology: the packaging bags to be processed need to be positioned by inserting a support rod into the handle hole on the packaging bag so that the subsequent bag picking and placing mechanism can accurately pick up the packaging bag. This operation requires the worker to manually insert the handle hole on the packaging bag into the support rod, which is time-consuming and labor-intensive. In addition, the fit between the support rod and the handle hole is relatively tight, which means that the worker needs to constantly adjust the packaging bag when loading the material and overcome a lot of friction, so the loading efficiency is low. Utility Model Content
[0005] To address the aforementioned problems, the purpose of this utility model is to provide a packaging bag suction and positioning structure that allows operators to accurately pick up packaging bags without requiring them to perform meticulous sorting, as well as a packaging bag feeding mechanism that utilizes the same structure.

[0021] The beneficial effects of this utility model are as follows: Since the positioning column is integrated into the material handling assembly, during loading, the stacked packaging bags are slightly arranged and placed in the direction directly opposite the positioning column. During material handling, the first driving device first drives the positioning column to move along a first direction towards the packaging bag.

[0029] Reference Figures 1 to 2 A packaging bag suction and positioning structure, comprising:
[0030] A material handling assembly, wherein a first driving device 10 and a second driving device are provided on the material handling assembly;
[0031] Positioning post 20 is mounted on the first driving device 10. The first driving device 10 is used to drive the positioning post 20 to move in a first direction. The end of the positioning post 20 is provided with a guide slope 22. The positioning post 20 is used to cooperate with the packaging bag material, preferably with the handle hole on the packaging bag material, or it can cooperate with the four sides or other parts of the packaging bag material for positioning.
[0032] A bag-taking device 30 is mounted on the second driving device, which drives the bag-taking device 30 to move.
[0033] This utility model also discloses a packaging bag feeding mechanism, including the above-mentioned packaging bag suction and positioning structure, and further including:
[0034] The loading platform is provided with a loading station for placing packaging bags to be processed, and the loading station is provided with a clearance hole;
[0035] The first direction is the vertical direction, the loading platform is located directly below the material receiving assembly and the clearance hole is located directly below the positioning post 20, the clearance hole is used to avoid the positioning post 20.
[0036] Because the positioning post 20 is integrated into the material handling assembly, during loading, the stacked packaging bags are slightly arranged and placed in the direction directly opposite the positioning post 20. During material handling, the first drive device 10 first drives the positioning post 20 to move along the first direction towards the packaging bag. The guide slope 22 at the end of the positioning post 20 allows the positioning post 20 to be inserted into the handle hole of the packaging bag. The guide slope 22 cooperates with the edge of the packaging bag to adjust the position of the packaging bag, so that the packaging bag is precisely adjusted to the correct position and orientation. Then, the second drive device drives the bag picking device 30 to move to the surface of the packaging bag to clamp the packaging bag. Afterwards, the first drive device 10 drives the positioning post 20 to reset, so that the bag picking device 30 can easily transfer the packaging bag. In this way, operators no longer need to carefully place the bags on the loading station, saving time and effort, reducing production time, and increasing efficiency. The packaging bag feeding mechanism disclosed in this solution adds a feeding platform to the packaging bag suction and positioning device. The feeding platform is equipped with a feeding station for placing stacked packaging bags, and the positioning column 20 moves in a vertical direction, which facilitates the placement of packaging bags.
[0037] In this design, to facilitate the insertion of the positioning post 20 into the handle hole of the packaging bag and to make the positioning post 20 easier to process, the end of the positioning post 20 is preferably tapered.
[0038] Considering that the handle hole of the packaging bag is generally strip-shaped, in order to facilitate the positioning post 20 having a certain width to position the handle hole, it is preferable that the positioning post 20 includes two oppositely arranged halves 21, and the outer edges of the ends of the two halves 21 are provided with the guide slope 22. Through the structural arrangement of the two halves 21, the edge of the strip-shaped handle hole can be fitted while saving materials.
[0039] Considering that the sizes of the handle holes on different packaging bags are different, in order to facilitate the use of packaging bags of various sizes, it is preferable that the output end of the first driving device 10 is provided with a mounting plate 23. The mounting plate 23 is provided with two sets of fixing holes 24. The positioning post 20 can be detachably fixed to the fixing holes 24. By replacing the positioning post 20 with different specifications, it can be used to correspond to packaging bags of different specifications.
[0040] Further optimization is made by preferably using a strip-shaped fixing hole 24, which allows the distance between the two halves 21 to be adjusted by adjusting the position of the half 21 on the fixing hole 24, thus accommodating packaging bags of different specifications.
[0041] To further optimize the structure and make it more streamlined and rational, it is preferable that the material handling assembly is provided with a back plate 11, on which a first track 12 is provided along a first direction. A support plate 13 is slidably mounted on the first track 12, and a mounting plate 23 is disposed on the support plate 13. The first driving device 10 is a cylinder disposed on the back plate 11 and connected to the support plate 13. In this design, the support plate 13 and the mounting plate 23 can also be integrally formed.
[0042] Further optimization is preferred. The bag-retrieving device 30 includes a movable frame 31 and a clamp 32 disposed at the end of the movable frame 31. The second driving device includes a third sub-drive 33, which is used to drive the movable frame 31 to move the clamp 32 along a first direction.
[0043] Further optimization is preferred, where the output end of the third sub-drive 33 is provided with a pressure plate 331 for movably abutting against the surface of the movable frame 31 and driving the movable frame 31 to move along a first direction. A return spring 34 is provided on the movable frame 31. During operation, the pressure plate 331 abuts against the movable frame 31, thereby driving the movable frame 31 to move along the first direction, causing the clamp 32 to move to the surface of the packaging bag to clamp it. After complete clamping, the third sub-drive 33 drives the pressure plate 331 to reset, and then the return spring 34 drives the movable frame 31 and clamp 32 to reset, thereby transferring the packaging bag. The third sub-drive 33 is preferably a cylinder, but it can also be a hydraulic cylinder, a telescopic motor, or other implementations.
[0044] Based on this, the preferred bag-removing device 30 includes a main board 35, a guide post 36 is provided on the main board 35, the movable frame 31 is installed on the guide post 36, and the reset spring 34 is sleeved on the outer periphery of the guide post 36.
[0045] Further optimization is made considering that the processing station for packaging bags and handles is often two or more spatially distant from the feeding station. Therefore, it is preferable that the material handling assembly is provided with a second track 37 arranged along the second direction, the main board 35 is slidably mounted on the second track 37, and the second driving device includes a fourth sub-drive 38 connected to the main board 35 and driving the main board 35 to move along the second track 37.
[0046] In this design, the fourth sub-drive 38 is preferably a servo motor, and the output end of the servo motor is equipped with a transmission belt that is connected to the main board 35. The fourth sub-drive 38 can also be a lead screw motor assembly or other implementations.
[0047] Based on the above structure, the operating mode of the packaging bag suction and positioning structure and the packaging bag feeding mechanism using it disclosed in this solution is as follows:
[0048] First, stack the packaging bags in piles and place them on the loading station of the loading platform. Then, do some simple tidying so that the buckle holes on all the packaging bags overlap accordingly, but there is no need to finely adjust the position of each packaging bag.
[0049] Then, the first drive moves the positioning column 20 downwards. The positioning column 20, through the guide ramp 22 at its end, inserts into the handle hole of the first stacked packaging bag from the top, and correspondingly into the handle holes of several other packaging bags at the bottom. Since the packaging bags themselves have a certain strength, as the positioning column 20 moves downwards, the guide ramp 22 drives the packaging bags to move, thereby adjusting the packaging bags to the accurate position. Afterwards, the pressure plate 331 of the third sub-drive 33 presses the movable frame 31 downwards, causing the movable frame 31 to move the clamp 32. The first packaging bag is moved to the surface of the first packaging bag to clamp the first packaging bag. After successful clamping, the positioning post 20 is reset by the first drive, thereby disengaging the positioning post 20 from the handle hole of the packaging bag. At the same time, the third sub-drive 33 drives the pressure plate 331 to reset, so that the movable frame 31 rises under the action of the reset spring 34. Since the pressure plate 331 only drives the movable frame 31 to move by abutting and pressing down rather than being completely fixed to the movable frame 31, the fourth sub-drive 38 can drive the main board 35 to move along the second track 37, thereby transferring the packaging bag along the second direction.
[0050] In other embodiments, the second driving device may also be a three-dimensional robotic arm or the like.
[0051] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
