[0035] Refer to Figure 1 、 Figure 2As shown, a bag supply centering mechanism of the present utility model includes a bag supply frame 8, and the following are provided in the bag supply frame 8:

[0036] A baffle assembly, including a first baffle 1 and a second baffle 2 that can move along the bag supply frame 8 respectively and are oppositely arranged;

[0037] An adjusting assembly, including an adjusting screw 3, a first seat body 4 and a second seat body 5. The adjusting screw 3 includes a first end thread and a second end thread with opposite helix directions. A first end nut and a second end nut that are threadedly connected to the first end thread and the second end thread respectively and are connected to the first seat body 4 and the second seat body 5 are provided. The first seat body 4 is connected to the first baffle 1, and the relative distance between the first seat body 4 and the second seat body 5 can be adjusted by rotating the adjusting screw 3;

[0038] A telescopic mechanism 6 is installed on the second seat body 5 and can move along with the second seat body 5. The telescopic end of the telescopic mechanism 6 is connected to the second baffle 2.

[0039] It can be understood that one of the first end thread and the second end thread is a left-handed thread and the other is a right-handed thread.

[0040] In one embodiment, it further includes a guide rod 77. The first seat body 4 is provided with a first linear bearing group 41, and the second seat body 5 is provided with a second linear bearing group 51. The guide rod 77 is slidably connected to the first linear bearing group 41 and the second linear bearing group 51.

[0041] In one embodiment, first limit seats 42 and second limit seats 52 connected to the bag supply frame 8 are respectively arranged on the sides of the two ends of the guide rod 77 corresponding to the first seat body 4 and the second seat body 5.

[0042] The settings of the first limit seat 42 and the second limit seat 52 ensure the position stability of both ends of the guide rod 77 during the adjustment process, avoid excessive movement or position deviation that may occur during the adjustment process, and further improve the safety and accuracy of the operation.

[0043] Specifically, the number of the guide rods 77 is two and they are symmetrically arranged on both sides of the adjusting screw 3.

[0044] The configuration of the guide rod 77 and the linear bearing group ensures the smooth sliding of the first seat body 4 and the second seat body 5 during the adjustment process. The double-guide rod 77 design and its symmetrical arrangement ensure the balanced force on both sides of the adjusting screw 3, making the adjustment process smoother and more efficient.

[0045] In one embodiment, the bag supply frame 8 includes a support guide rail 81, and a roller 22 that rolls on the support guide rail 81 is installed at the bottom end of the second baffle 2.

[0046] The design of the support rail 81 and the roller 22 makes the movement of the second baffle 2 smoother. The roller 22 rolls on the support rail 81, reducing the frictional resistance, improving the movement efficiency and stability of the baffle, and ensuring a smooth centering process.

[0047] In one embodiment, the telescopic mechanism 6 includes a cylinder, and a connecting plate 61 welded to the second seat body 5 is installed at the head end of the cylinder.

[0048] In one embodiment, an adjusting handwheel 31 connected to the end of the adjusting screw 3 is provided outside the bag supply frame 8. When the adjusting handwheel 31 rotates clockwise (or counterclockwise), the distance between the baffles decreases; when the adjusting handwheel 31 rotates in the other direction, the distance between the baffles increases, making it applicable to packaging bags of various sizes, with strong versatility and flexibility.

[0049] Refer to Figure 3 As shown, during operation, there are a first bag storage position 82 and a second bag storage position 83 on the bag supply frame 8. The packaging bag is placed in the first bag storage position 82. When the adjusting handwheel 31 rotates in one direction, the distance between the first baffle 1 and the second baffle 2 decreases; when the adjusting handwheel 31 rotates in the other direction, the distance between the first baffle 1 and the second baffle 2 increases; through the adjustment of the adjusting handwheel 31, it can adapt to different specifications of packaging bags for centering operations;

[0050] When the cylinder retracts to the right, it drives the second baffle 2 to move towards the first baffle 1, and at the same time drives the packaging bag to move from the first bag storage position 82 to the second bag storage position 83, completing the bag supply centering operation, and the packaging bag enters the next action process. By adjusting the left and right positions of the cylinder, it ensures the precise adjustment of the left and right positions during the centering process of the packaging bag. By shaking the adjusting handwheel 31, the adjusting screw 3 with left and right threads rotates to adjust the centering width to adapt to packaging bags of different widths.

[0051] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
