[0026] The bag clamping and conveying mechanism provided in the embodiment of the utility model is suitable for the packaging equipment of the cable tie, which clamps the packaging bag and lifts and conveys it. Figures 1 to 5As shown, it includes a body 1, a mounting frame 2 and a lifting drive mechanism 3; the mounting frame 2 is arranged on the body 1 and can be moved up and down, and is driven by the lifting drive mechanism 3 to move up and down; the mounting frame 2 includes a side frame A21 and a side frame B22 spaced apart along the transverse direction, and a fixed column 23 that fixes the side frame A21 and the side frame B22, and the fixed column 23 fixes the side frame A21 and the side frame B22 to form a mounting frame 2 with a stable structure; it also includes two movable arms 4 arranged on the fixed column 23 and movable along the length direction of the fixed column 23, and two electric screw mechanisms that respectively drive the two movable arms 4 to move, and clamping assemblies 41 are fixed to corresponding positions on the two movable arms 4; a first slide rail 24 and a second slide rail 25 arranged along the length direction thereof are fixed on the fixed column 23, and the first slide rail 24 is fixed with a second slide rail 25. The sliding connection has two first slides 241 fixedly connected to the two movable arms 4 respectively, and the second slide rail 25 has two second slides 251 fixedly connected to the two movable arms 4 respectively. In this embodiment, two electric screw mechanisms independently drive the two movable arms 4 respectively, and the two movable arms 4 can move along the fixed column 23. The distance between the two movable arms 4 is adjustable. The two movable arms 4 can be moved to a suitable position to clamp packaging bags of different widths through the clamping assembly 41, and each movable arm 4 forms a sliding connection with the first slide rail 24 and the second slide rail 25 through the first slide 241 and the second slide 241 to achieve flexible, smooth and stable movement. This precise mechanical structure design can well meet the clamping and upward and downward transfer requirements of packaging bags of various widths.

[0028] In some embodiments, as Figure 2 and Figure 3As shown, the electric screw mechanism includes a first screw 51 driven to rotate by the first servo motor 5 and a first screw sleeve 52 cooperating with the first screw 51. The servo motor has good programmability. By programming and controlling the servo motor, the displacement, speed and acceleration of the screw can be accurately controlled; the two ends of the first screw 51 are respectively connected to the side frame A21 and the side frame B22 through bearings, and the first servo motors 5 in the two electric screw mechanisms are fixed on the side frame A21.

The gear portion 441 is engaged with the rack portion 422. When the first clamping member 42 moves, it drives the second clamping member 44 to swing, thereby controlling the clamping arm A421. The opening and closing between the clamping arm A421 and the clamping arm B442 clamps the packaging bag when the clamping arm A421 and the clamping arm B442 are aligned, and the packaging bag can be loosened when the clamping arm A421 and the clamping arm B442 are separated; a limiting member 45 is also fixed on the movable arm 4, and the limiting member 45 is provided with a guide through-hole matching the cylinder rod 431 of the driving cylinder 43, and the cylinder rod 431 passes through the guide through-hole and is fixedly connected to the first clamping member 42, and the guide through-hole can provide guidance for the cylinder rod 431, thereby improving the overall movement accuracy and stability.

[0035] like Figure 5 As shown, the limiting member 45 is L-shaped, and the inner side of one wall panel of the limiting member 45 forms a planar sliding contact with the rack portion 422, which can provide effective support for the first clamping member 42 and enhance stability during the activity; the guide through hole is provided on the other wall panel of the limiting member 45, and the second clamping member 44 can be rotatably mounted on the movable arm 4 through a positioning pin; the first clamping member 42 is L-shaped, and the second clamping member 44 is on the inner side of the first clamping member 42.
