Both sides of the upper ends of the feed plates 2 are rotatably connected to the support block 18 through the rotating shafts 17, so that the feed plates 2 can rotate with the rotating shafts 17 as the support points. Then, the feed cylinder 3 drives the feed plates 2 to rotate through the second connection bracket 11, so that the two feed plates 2 can open and close the feed hopper 1.

[0029] A bag pressing plate 4 is movably provided on the outer side of the lower end of the feed plate 2. The bag pressing plate 4 is opened or closed by a bag clamping cylinder 5;

[0030] A first connecting plate 13 is fixedly provided near the upper end on the outer side of the feed plate 2. A second connecting plate 14 is fixedly provided on the end face of the bag pressing plate 4. The output end of the bag clamping cylinder 5 is rotatably connected to one end of the second connecting plate 14, and the other end of the bag clamping cylinder 5 is rotatably connected to the first connecting plate 13;

[0033] The bag pressing plate 4 is made of rubber material.

[0034] Among them, the pressing bag plate 4 is used to fix the M bag. When feeding the M bag, first put the opening of the M bag on the outside of the lower end of the feeding plate 2, and then drive the second connecting plate 14 by the bag clamping cylinder 5 to rotate with the fixed shaft 12 as the fulcrum, so that the second connecting plate 14 drives the pressing bag plate 4 to move towards the M bag, making the M bag be pressed by the pressing bag plate 4 on the feeding plate 2. The pressing bag plate 4 is made of rubber material and has elasticity, so it can clamp the M bag.

The pressing bag plate 4 is made of rubber material and has elasticity, so it can clamp the M bag. The two upper ends of the feeding plate 2 are rotatably connected to the support blocks 18 through the rotating shafts 17, so that the feeding plate 2 can rotate with the rotating shafts 17 as the support points. Then, the feeding cylinder 3 drives the feeding plate 2 to rotate through the second connecting bracket 11, so that the two feeding plates 2 open the feeding hopper 1 to fill the M bag with materials. After filling, the two bag supporting cylinders 6 drive the two groups of bag supporting cylinders 7 to pull towards the outside of the M bag at the same time, so that the M bag can be expanded by the bag supporting cylinders 7. At the same time, the folding angle cylinder 8 drives the folding angle plate 9 to push towards the folding line position of the M bag. With one push and one pull, the M shape is folded, and then the bag is sealed. The operation is fast, simple and convenient.
