[0026] Please see Figures 1-3 As shown, this embodiment is an automatic PE bag opening mechanism, including:

[0027] Pre-opening components and expanded components;

[0028] The pre-opening assembly includes a slide rail 11, a slider 12, a fixing plate 13, a vertical plate 14, a first cylinder 15, a moving block 16, a connecting frame 17, an upper suction cup 18, and a lower suction cup 192. The slide rail 11 and the slider 12 are arranged as a set. The slider 12 is slidably connected to the surface of the slide rail 11. The fixing plate 13 is fixed between the tops of adjacent sliders 12 on one side. The vertical plate 14 is fixed to one side of the top of the fixing plate 13. The first cylinder 15 is fixed to one side of the upper end of the vertical plate 14. The moving block 16 is fixed to the output end of the first cylinder 15. The connecting frame 17 is fixed to the top of the moving block 16. The upper suction cup 18 is fixed to the bottom of the other end of the connecting frame 17. The lower suction cups 192 are arranged as a set and are all located below the upper suction cup 18.

[0029] The slide rail 11 is used for the movement of the slider 12. The slider 12 is used for the connection between the fixed plate 13 and the fixed frame 21. The fixed plate 13 is used for the connection between the vertical plate 14 and the fixed rod 19. The vertical plate 14 is used for the connection of the first cylinder 15. The first cylinder 15 is used to push the moving block 16 and the connecting frame 17 to move. The moving block 16 is used for the connection of the connecting frame 17. The connecting frame 17 is used for the connection of the upper suction cup 18. The upper suction cup 18 and the lower suction cup 192 are used together to pre-open the PE bag. There are two lower suction cups 192.

[0030] A fixing block 191 is fixedly connected to the bottom end of the lower suction cup 192, and a fixing rod 19 is fixedly connected to one end of the fixing block 191. The bottom end of the fixing rod 19 is fixedly connected to the top end of the fixing plate 13.

[0031] The fixing block 191 is used to connect the lower suction cup 192, and the fixing rod 19 is used to support the lower suction cup 192. When the first cylinder 15 drives the connecting frame 17 to move through the moving block 16, it causes the upper suction cup 18 to move, so that the upper suction cup 18 drives the PE bag to pre-open.

[0032] The expansion assembly includes a fixed frame 21, a guide rail 22, a moving block 23, a second cylinder 24, a sliding block 25, and a support rod 26. The fixed frame 21 is fixed to the top of the horizontally adjacent slider 12 on the other side. The guide rail 22 is fixed to the middle of the top of the fixed frame 21. The moving blocks 23 are arranged in a group and are slidably connected to both ends of the surface of the guide rail 22. The second cylinder 24 is fixed to the top of the moving block 23. The sliding blocks 25 are arranged in a group and are fixed to the output end of the second cylinder 24. Each group of sliding blocks 25 slides in opposite directions. The support rod 26 is fixed to one side of the opposite end of each group of sliding blocks 25.

[0033] The fixed frame 21 is used to connect the guide rail 22. The guide rail 22 is used to connect and move the moving block 23. The moving block 23 is used to connect the second cylinder 24. The second cylinder 24 is used to connect the sliding block 25. The sliding block 25 is used to connect the support rod 26. The support rod 26 is used to open the PE bag opening. There are two sliding blocks 25 in each group.

[0034] A mounting box 211 is fixedly connected to one side of the mounting frame 21, a servo motor 212 is fixedly connected to one side of the bottom end of the mounting box 211, and a sensor 213 is fixedly connected to one edge of the bottom end of the inner side of the mounting frame 21.

[0035] Mounting box 211 is used to connect servo motor 212, which is used to move slider 12 and moving block 23. Sensor 213 is used to sense PE bag, which causes sensor 213 to drive the positive and negative lead screw 28 to start. Sensor 213 is a photoelectric sensor.

[0036] The bottom two sides of the second cylinder 24 are fixedly connected to mounting blocks 27, and the mounting blocks 27 are slidably connected to the center of the top of the fixing frame 21.

[0037] The bottom end of the mounting block 27 extends to the middle end of the inner side of the fixing frame 21, and the inner sides of the bottom end of the mounting block 27 are fixedly connected by positive and negative screws 28.

[0038] Mounting block 27 is used to connect the positive and negative lead screws 28. The positive and negative lead screws 28 are used to drive the moving block 23 to move in opposite directions or relative to each other. The second cylinder 24 drives the sliding block 25 to move in opposite directions or relative to each other, so that the sliding block 25 drives the support rod 26 to move, causing the support rod 26 to open the pre-opened bag opening.

[0039] Working principle: During use, the PE bag is conveyed to the space between the upper suction cup 18 and the lower suction cup 192 via the conveying device. The first cylinder 15 is activated, causing the upper suction cup 18 to move downwards, which in turn causes the upper suction cup 18 and the lower suction cup 192 to squeeze the PE bag between their inner sides. This allows the upper suction cup 18 and the lower suction cup 192 to suck up and hold the PE bag on both sides. Then, the first cylinder 15 drives the connecting frame 17 to move upwards, causing the connecting frame 17 to move the upper suction cup 18 in opposite directions. This allows the upper and lower suction cups to pre-open the PE bag. Finally, the slider 12 drives the fixing frame 21 to move up and down the suction cups. The direction of movement causes the support rod 26 to extend into the PE bag opening in a closed state. At this time, the sensor 213 senses that the distance between it and the fixed plate 13 has decreased. Then, the positive and negative screws 28 are activated, causing the positive and negative screws 28 to drive the moving block 23 to move in opposite directions through the mounting block 27. This causes the positive and negative screws 28 to drive the support rod 26 to support both ends of the inner side of the PE bag opening. Then, the second cylinder 24 drives the sliding block 25 to move in opposite directions, causing the sliding block 25 to drive the support rod 26 to move together. This causes the support rod 26 to open the PE bag opening into a rectangle so that the product can enter the PE bag through the opening.

[0040] The above steps can improve its functionality.
