[0031] A limiting block 21 is fixedly installed on one side of the support frame 2. The support frame 2 is snapped into the slide rail groove 12 by the limiting block 21. The limiting block 21 is a T-shaped structure that is adapted to the slide rail groove 12. An installation groove a121 is opened on the upper surface of the slide rail groove 12. A hydraulic cylinder 122 is fixedly installed in the installation groove a121. One end of the piston rod of the hydraulic cylinder 122 is fixedly installed on one side of the limiting block 21. The hydraulic cylinder 122 drives the support frame 2 to move up and down, so as to move the packaging bag and adjust the distance between the packaging bag and the material cylinder 11.

[0032] The support frame 2 has several through slots 24 symmetrically opened on its side wall. A cylinder b241 is fixedly installed in the through slot 24. One end of the piston rod of the cylinder b241 is fixedly installed on one side of the mounting frame 3. The cylinder b241 pushes the mounting frame 3 to move, so as to adjust the distance between the two mounting frames 3 to clamp packaging bags of different sizes.

[0033] Several mounting blocks 23 are symmetrically fixedly installed on the lower surface of the support frame 2. The side wall of the mounting block 23 has a mounting groove b231. A cylinder a232 is fixedly installed in the mounting groove b231. A suction cup 233 is fixedly installed at one end of the piston rod of the cylinder a232.

Several telescopic grooves a333 are symmetrically formed on the side wall of the clamping blocks a333. Clamping blocks b331 are slidably installed within the telescopic grooves a333. Springs a334 push the clamping blocks b331 to conform to the packaging bag, improving the clamping stability. Springs b343 at the bottom of the telescopic grooves b341 pull the connecting block 34, which in turn moves the support block 342 to clamp packaging bags of different sizes. Cylinder b241 pushes the mounting frame 3 to adjust the distance between the two mounting frames 3 to clamp packaging bags of different sizes. Mounting blocks 23 are symmetrically fixed on the lower surface of the support frame 2. Cylinder a232 is fixedly installed inside the mounting blocks 23. A suction cup 233 is fixedly installed at one end of the piston rod of cylinder a232. The suction cup 233 contacts the packaging bag to drive the packaging bag to unfold. Hydraulic cylinder 122 drives the support frame 2 to move up and down. Several claws 111 are fixedly installed in a circular array on the lower surface of the material cylinder 11. The packaging bag is opened by the suction cup 233. The hydraulic cylinder 122 drives the support frame 2 to move, so that the claws 111 support the packaging bag, so that the material in the material cylinder 11 can enter the packaging bag.
