Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-5 A feeding mechanism for packaging bags includes a profile frame 1 made of high-strength aluminum alloy, characterized by its light weight, high strength, and corrosion resistance. A mounting plate 2 is provided at one end of the top of the profile frame 1, and its surface is treated with rust prevention. Switch mounting seats 3 are symmetrically arranged on both sides of the top surface of the mounting plate 2. A photoelectric detection switch 19 is provided on the top of each of the two sets of switch mounting seats 3. Four sets of limit posts 4 are provided at one end of the top of the mounting plate 2, and a tooling plate 5 is slidably connected to the surfaces of the four sets of limit posts 4. Four sets of limiting posts 4 together provide sliding guidance for the tooling plate 5. Four sets of slots are opened at one end of the top of the tooling plate 5. Each of the four slots holds a packaging bag material box 6, and each packaging bag 7 is held inside the packaging bag material box 6. A process hole is opened at one end of each of the four slots, and a blocking shaft 8 is held inside the process hole. Separating plates 9 are horizontally arranged on the top of the tooling plate 5. A lead screw 12 is installed in the middle of the bottom surface of the tooling plate 5. Support posts 10 are installed around the bottom of the tooling plate 5. The surfaces of the four sets of support posts 10... All four sets of support columns 10 are connected to the interior of the mounting plate 2. A movable plate 11 is provided at the bottom of each of the four sets of support columns 10. The top of the movable plate 11 is located at the bottom of the mounting plate 2. The threaded surface of the lead screw 12 passes through the middle of the movable plate 11. Four linear bearings 17 are provided on the top surface of the movable plate 11. Sliding rods 13 are slidably connected inside each of the four sets of linear bearings 17. The tops of the four sets of sliding rods 13 are located around the bottom surface of the mounting plate 2. A base plate 14 is provided at the bottom of each of the four sets of sliding rods 13. The top of 4 is located at the bottom of the movable plate 11. A motor mounting base 15 is provided in the middle of the bottom surface of the base plate 14. A servo motor 16 is installed inside the motor mounting base 15. The servo motor 16 provides the power for the mechanism to move up and down. A transmission rod is provided at the output end of the servo motor 16. The top of the transmission rod is connected to the bottom of the lead screw 12. Anti-slip pads 18 are provided around the bottom of the profile frame 1. The four sets of anti-slip pads 18 are made of nitrile rubber to increase the friction with the ground and ensure the stability of the equipment operation.

[0027] Both the photoelectric detection switch 19 and the servo motor 16 are connected to the external control system via power lines. The external equipment can uniformly regulate their start / stop, operating parameters and power output to ensure that the two work together to achieve automated coordination of accurate detection and stable material feeding.

[0028] Reference Figure 4 There are five sets of separation plates 9, and a packaging bag material box 6 is set between every two sets of separation plates 9. The surface of the blocking shaft 8 is attached to one end of the packaging bag material box 6 and limits the packaging bag material box 6 to prevent the packaging bag material box 6 from shifting during the operation of the feeding mechanism. When the material in the packaging bag material box 6 is exhausted, the blocking shaft 8 is removed manually, the empty packaging bag material box 6 is removed, and the pre-prepared full packaging bag material box 6 is inserted into the tooling plate 5 to achieve rapid replenishment. Specific Implementation Example 2:

[0030] A feeding mechanism for packaging bags, further based on the basic structure in Specific Embodiment 1, operates as follows: First, packaging bag boxes 6 containing packaging bags 7 are sequentially snapped into the slots at the top of the tooling plate 5, and positioned using the blocking shaft 8. Then, the servo motor 16 is activated, driving the lead screw 12 to rotate. The lead screw 12, through its threaded engagement with the movable plate 11, drives the tooling plate 5 to descend vertically along the limiting post 4 and the sliding rod 13. When the tooling plate 5 descends to a certain height, the photoelectric detection switch 19 detects the tooling plate 5, and the servo motor 16 stops rotating. At this point, the tooling plate 5 is in a suitable feeding position. Subsequent equipment can then remove packaging bags 7 from the packaging bag boxes 6 for packaging operations. When the number of packaging bags 7 in the packaging bag boxes 6 decreases and needs to be replenished, the servo motor 16 rotates in the opposite direction, driving the tooling plate 5 to rise, facilitating the operator to replace the packaging bag boxes 6 with new ones containing packaging bags 7, thereby achieving continuous feeding of packaging bags 7.

[0031] In summary:

[0032] 1. The replaceable packaging bag material box 6 design makes the feeding operation more convenient and efficient, perfectly matching the automated production cycle. Operators can replace the packaging bag material box 6 in seconds without re-adjusting the equipment, completely avoiding the production interruption problems caused by traditional feeding methods;

[0033] 2. The separation plate 9 effectively separates the packaging bags 7, preventing them from sticking together and ensuring a smooth feeding process;

[0034] 3. A servo motor 16 drives the lead screw 12 to achieve precision transmission. The photoelectric detection switch 19 is used to monitor the material position in real time. At the same time, the sliding rod 13 structure is used to ensure the stability and guiding accuracy during the movement, thereby effectively improving the positioning accuracy and feeding reliability of the packaging bag 7, and realizing automated and precise feeding.
