[0036] The bottom end of cylinder body 6 is fixed to the inner edge of the top surface of rotary disc 4.

[0037] A plurality of elastic extension mechanisms 8 respectively include a rod 8.2 elastically sleeved in the radial direction on the top end of the side wall of the cylinder body 6. Wherein, the elastic extension mechanism 8 further includes a shell 8.1 fixed to the top end of the inner peripheral wall of the cylinder body 6 in the radial direction, both ends of the shell 8.1 are slidingly sleeved with the rod 8.2, a spring 8.4 located in the inner cavity of the shell 8.1 and sleeved on the rod 8.2, and a support wheel 8.5 installed on the inner end of the rod 8.2, and a fixed ring 8.3 is fixedly sleeved on the part of the rod 8.2 between the inner end of the spring 8.4 and the inner wall of the shell 8.1.

[0038] The packaging bag storage box 10 includes a rectangular outer shell 10.1 fixed to the left side of the top surface of the fixed outer ring 3, a push plate 10.2 slidingly clamped in the inner cavity of the rectangular outer shell 10.1, and a plurality of elastic members 10.3 vertically connected between the push plate 10.2 and the outer side wall of the inner cavity of the rectangular outer shell 10.1, and the middle part of the inner side wall of the rectangular outer shell 10.1 is provided with an opening slot 10.1.1 in the vertical direction.

[0039] The bottom of the rear end of the chute 12 is fixed to the top surface of the front end of the fixed outer ring 3, and the front end of the chute 12 is lower than the rear end.

[0040] The rear end of the piston cylinder of the telescopic cylinder 11 is fixed to the rear side of the outlet of the quantitative filling mechanism 1, and the rear end of the telescopic cylinder 11 is fixed to the front wall of the bracket 1.1.

[0041] The vacuum suction accessory 9 is fixed to the outer end of the rod 8.2 and the front end of the piston rod of the telescopic cylinder 11.

[0043] In summary, the packaging bags are placed in the cuboid shell 10.1 in a stacked manner, and the packaging bags are arranged inside the push plate 10.2. Under the pushing action of the elastic member 10.3, the push plate 10.2 pushes the stacked packaging bags inward, so that the packaging bag close to the direction of the cylinder 6 always adheres to the inner side position of the opening slot 10.1.1.

[0044] The driving mechanism 5 drives the rotation of the rotating disc 4. The driving mode is intermittent driving, that is, the rotating disc 4 pauses for a period of time every 90° rotation. When the cylinder 6 rotates to the position opposite to the opening slot 10.1.1 of the packaging bag storage tank 10, the support wheel 8.5 is subjected to the action of the outer convex arc surface 7.2, which pushes the rod 8.2 outward, so that the fixed ring 8.3 compresses the spring 8.4, and the rod 8.2 pushes the vacuum suction accessory 9 towards the opening slot 10.1.1, and the suction cups 9.3 absorb and grab the packaging bag close to the bag opening position on the innermost side through the opening slot 10.1.1.

[0046] The rotary disc 4 carrying the bagged plastic particles continues to rotate to the sealing mechanism to complete the sealing process.

[0047] The bagged plastic particles continue to rotate with the rotary disc 4, and the suction disc 9.3 on the corresponding elastic telescopic mechanism 8 is always in the suction state to avoid the bagged plastic particles from falling. When rotating to the front side, the rod 8.2 will be extended forward by a certain distance under the action of the middle arc surface 7.1, and the suction disc 9.3 is released from the suction to push the bagged plastic particles into the chute 12, which slides forward under the action of the chute 12 to complete the discharging process.

[0048] Among them, the vacuum pump equipment matched with the vacuum suction accessory 9 installed on the elastic telescopic mechanism 8 is installed on the inner wall of the cylinder 6. The vacuum pump equipment matched with the vacuum suction accessory 9 on the opening telescopic cylinder 11 is arranged on the periphery of the fixed outer ring 3, which can avoid the complexity of air suction and exhaust for the rotating structure.

[0049] In order to avoid the friction between the suction disc 9.3 of the vacuum suction accessory 9 and the two side walls of the opening slot 10.1.1, the inner side wall of the cuboid shell 10.1 is provided with a slope 10.1.2 at the positions before and after the opening slot 10.1.1.
