[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 As shown, a packaging bag feeding mechanism includes a mounting frame 1, a vibration structure 3 on the mounting frame 1, a sliding plate 301 on the vibration structure 3, a guide rod 302 fixedly connected to the mounting frame 1, the sliding plate 301 and the guide rod 302 being slidably connected, a spring 303 being fixedly connected between the sliding plate 301 and the mounting frame 1, and a vibration motor 304 mounted on the sliding plate 301.

[0024] As a technical optimization of this utility model, the mounting frame 1 is provided with a bag feeding structure 2, which includes a mounting shaft 201. The mounting shaft 201 is rotatably connected to the mounting frame 1, and a mounting plate 202 is fixedly connected to the mounting shaft 201. A hydraulic rod 204 is mounted on the mounting plate 202, and an adjusting rod 205 is installed on the telescopic end of the hydraulic rod 204. When the telescopic end of the hydraulic rod 204 retracts, the servo motor 203 is started. The output shaft of the servo motor 203 rotates, driving the mounting shaft 201 to rotate. The rotation of the mounting shaft 201 drives the mounting plate 202 to rotate, thereby adjusting the angle of the hydraulic rod 204. After rotating 90 degrees, the hydraulic rod 204 continues to extend, smoothly delivering the packaging bag to the subsequent equipment. To complete the bag feeding process, four sliders 206 are slidably connected to the adjusting rod 205. The sliders 206 are slidably connected to the adjusting rod 205. A connecting pipe 207 is installed on the slider 206, and a suction cup 208 is installed on the connecting pipe 207. The connecting pipe 207 is connected to an external air source through an air pipe, which can work with the suction cup 208 to pick up the packaging bag. A knob 209 is threadedly connected to the slider 206. The knob 209 abuts against the adjusting rod 205. By sliding the slider 206 on the adjusting rod 205, after sliding to the correct position, the knob 209 is rotated to make it abut against the adjusting rod 205, and the adjustment can be easily completed. A servo motor 203 is installed on the mounting frame 1, and the mounting shaft 201 is fixedly connected to the output shaft of the servo motor 203.

[0025] As a technical optimization of this utility model, the slide plate 301 is provided with a guide structure 4, the guide structure 4 including a vertical plate 401. The vertical plate 401 is fixedly connected to the slide plate 301, and two slide rods 402 are slidably connected to the vertical plate 401. Multiple vertical rods 404 are fixedly connected to the slide rods 402. The packaging bag is first placed in the area enclosed by the vertical plate 401, the vertical rods 404, and the adjusting plate 406. The vertical plate 401, the vertical rods 404, and the adjusting plate 406 work together to accurately position the packaging bag and effectively prevent the packaging bag from shifting during the feeding process. A lead screw 403 is rotatably connected to the vertical plate 401, and the slide rods 402 are threadedly connected to the lead screw 403. The two ends of the lead screw 403 are connected to the vertical plate 401. With opposite thread directions, the lead screw 403 simultaneously drives the two vertical rods 404 to move towards the center, ensuring that the packaging bag is always in the center line position of the slide plate 301, thus guaranteeing the accuracy of subsequent bag retrieval. A rotating rod 405 is fixedly connected to the lead screw 403, and an adjusting block 407 is slidably connected to the slide plate 301. An adjusting plate 406 is fixedly connected to the adjusting block 407. By flexibly adjusting the positions of the vertical rods 404 and the adjusting plate 406, it can adapt to packaging bags of different sizes, enhancing the applicability of the mechanism. A bolt 408 is threadedly connected to the adjusting block 407, and the bolt 408 abuts against the slide plate 301. By tightening the bolt 408 against the slide plate 301, the stability between the adjusting block 407 and the slide plate 301 is improved.

[0026] In use, before feeding the bag, the packaging bag is placed within the area enclosed by the vertical plate 401, vertical rod 404, and adjusting plate 406. The vertical plate 401, vertical rod 404, and adjusting plate 406 work together to accurately position the packaging bag, effectively preventing it from shifting during feeding and improving the feeding efficiency of the entire feeding mechanism. When adjustments are needed for different sized packaging bags, the rotating rod 405 drives the lead screw 403 to rotate. The rotation of the lead screw 403 drives the two sliding rods 402 to slide towards each other. The sliding of the sliding rods 402 then drives the vertical rod 404 to move, thus adjusting the position of the vertical rod 404. The lead screw 403 simultaneously drives both sides... The vertical rod 404 moves towards the center to ensure that the packaging bag is always positioned at the center line of the slide plate 301, guaranteeing the accuracy of subsequent bag retrieval. To adjust the position of the adjusting plate 406, simply push the adjusting block 407 onto the slide plate 301; the adjusting block 407 will adjust the position of the adjusting plate 406. After adjustment, insert an Allen wrench into the bolt 408 and rotate it to tighten the bolt 408 against the slide plate 301. This tightening improves the stability between the adjusting block 407 and the slide plate 301. The flexible adjustment of the positions of the vertical rod 404 and the adjusting plate 406 allows for the adaptation to different sizes of packaging bags, enhancing the mechanism's versatility. During the packaging bag feeding stage, the vibration motor is activated. 304. When the vibration motor 304 operates, the slide plate 301 moves up and down continuously, sliding in cooperation with the guide rod 302. The guide rod 302 allows the slide plate 301 to slide more smoothly. Simultaneously, the slide plate 301 and the spring 303 work together to generate vibration. This vibration causes slight relative movement between the packaging bags, effectively breaking down any adhesions and separating the bags. This creates favorable conditions for the bag-picking unit to accurately pick up individual bags, thereby improving bag-picking efficiency. During the feeding process, the hydraulic rod 204 is activated, its telescopic end extends, driving the adjusting rod 205 to move. The adjusting rod 205 then drives the connecting pipe 207 downwards. The connecting pipe 207 causes the suction cup 208 to contact the topmost packaging bag, which is then... The connecting pipe 207 is connected to an external air source via an air pipe, which works with the suction cup 208 to pick up the packaging bag. After the packaging bag is picked up, the telescopic end of the hydraulic rod 204 retracts, and then the servo motor 203 is started. The output shaft of the servo motor 203 rotates, which drives the mounting shaft 201 to rotate. The rotation of the mounting shaft 201 drives the mounting plate 202 to rotate, thereby adjusting the angle of the hydraulic rod 204. When it rotates 90 degrees, the hydraulic rod 204 continues to extend, smoothly delivering the packaging bag to the subsequent equipment and successfully completing the bag feeding process. If it is necessary to adjust the position of the connecting pipe 207, the slider 206 slides on the adjusting rod 205. After sliding into place, the knob 209 is turned to make it press against the adjusting rod 205, and the adjustment can be easily completed.
