[0032] refer to Figure 2 , Figure 3 The top of the storage box 1 is fixedly connected to a limiting block 7, which is fixed at the right position in the middle of the top of the storage box 1. The inside of the limiting block 7 is slidably connected to a support assembly, which includes a rotating block 8, a limiting groove 9, a limiting rod 10 and a support plate 11. The outside of the rotating block 8 is slidably connected to the inner wall of the top of the limiting block 7, and the inclined surface of the rotating block 8 is slidably connected to the inner wall of the limiting block 7. The limiting groove 9 is opened in the middle of the top of the rotating block 8, and the outside of the limiting rod 10 is fixedly connected to The middle right side of the limit block 7 and the middle left side of the support plate 11 are fixedly connected to the right side of the limit block 7, the outside of the limit rod 10 is slidably connected to the inner wall of the limit slot 9, and the bottom end of the support plate 11 contacts the outside of the PVC plastic bag 6. Pull the support plate 11 to allow the limit slot 9 of the rotating block 8 connected to the support plate 11 to slide on the outside of the limit rod 10, so that the support plate 11 is upright and engaged, thereby supporting the PVC plastic bag 6 against the outside of the PVC plastic bag 6.

[0033] refer to Figure 4 , Figure 5 The top of the PVC plastic bag 6 is fixedly connected with a ferrule 12, the top of the PVC plastic bag 6 is fixedly connected with two handle straps 13, the inner top of the ferrule 12 is fixedly connected with a discharge opening 14, the outside of the discharge opening 14 is provided with a threaded strip 15, and a connecting component is opened on the left side of the ferrule 12.

[0034] The connecting component includes a notch 16 and two connecting strips 17. The notch 16 is opened on the left side of the ferrule 12. The bottom ends of the two connecting strips 17 on the far side are fixedly connected to the front and back sides of the inner wall of the notch 16. The top ends of the two connecting strips 17 on the far side are fixedly connected to the front and back sides of the inner wall of the notch 20. The interior of the sealing cover 18 is engaged with the exterior of the discharge opening 14. The bottom end of the sealing cover 18 contacts the top of the ferrule 12. The interior of the sealing cover 18 is provided with a threaded groove 19. The bottom left end of the sealing cover 18 is provided with a notch 20. The two sealing covers 18 and the ferrule 12 are connected by the sealing cover 18, the connecting strip 17 in the notch 20 and the connecting strip 17 at the notch 16 position of the ferrule 12, so that the sealing cover 18 will be placed on the outer edge of the ferrule 12 after rotation, which is convenient for users to find the sealing cover 18 for sealing operation.

[0035] Working principle: When the ink material in the bag needs to be taken out, the sealing cover 18 can be rotated first to make the thread groove 19 in the sealing cover 18 slide outside the thread strip 15 of the discharge opening 14, so as to open the discharge opening 14 along the lines of the thread strip 15. During the rotation of the sealing cover 18, the elastic force of the connecting belt 17 connecting the notch 20 of the sealing cover 18 and the notch 16 of the ferrule 12 pulls the sealing cover 18 so that the sealing cover 18 is hung on the outer edge of the discharge opening 14 after opening, so as to prevent the sealing cover 18 from being lost. The ink can be taken out at this time.

[0036] When the ink in the PVC plastic bag 6 is completely taken out, the bottom of the PVC plastic bag 6 can be pressed to compress the PVC plastic bag 6 to the position of the ring bag 5. At this time, the front and rear sides of the ring bag 5 are held in opposite directions by four fingers of both hands, and the ring bag 5 is twisted outward and inward in opposite directions to fold the ring bag 5 into a small cylinder. Then, through the connection of the rotating drum 3, the rotating drum 3 is rotated around the positioning shaft 2, so that the rotating drum 3 drives the folded ring bag 5, the PVC plastic bag 6 and other components to be stored in the storage box 1. Finally, the support plate 11 is pulled to drive the rotating block 8 upward, and the support plate 11 is rotated to make the left side of the support plate 11 rotate parallel to the top of the storage box 1.
