The bottom plate 1 is used to carry the power box 2. Both the bottom plate 1 and the power box 2 are prior arts and will not be described in detail herein. A rotating shaft 4 for winding the packaging paper bag is arranged on one side of the power box 2. A driving motor 3 is fixedly arranged inside the power box 2. The output end of the driving motor 3 is fixedly connected to one end of the rotating shaft 4. The driving motor 3 is a servo motor. Controlling the driving motor 3 through the power box 2 is a prior art and will not be described in detail herein. A fixed disk 5 is fixedly arranged on the outer side of the rotating shaft 4. A plurality of moving disks 6 are movably arranged on the outer side of the rotating shaft 4. A circular hole for the rotating shaft 4 to pass through is formed in the middle of the moving disk 6. A plurality of arc-shaped grooves 7 are respectively arranged through one side of the moving disk 6 and the fixed disk 5. A plurality of support rods 8 are movably arranged inside the moving disk 6 and the fixed disk 5.

[0024] Through the arrangement of the support rods 8, when winding the packaging cardboard, the support can be carried out according to the inner diameter of the inner support ring. Through the arrangement of the arc-shaped grooves 7, the plurality of support rods 8 can move uniformly outwards, so as to support the inner support ring, which can adapt to a variety of inner support rings. And the plurality of support rods 8 support from the inside of the inner support ring outwards, so that the inside of the inner support ring is supported in a circular shape outwards, ensuring the stability when the inner support ring is propped up.

[0025] Through the movably arranged moving disk 6, when the inner support ring is installed, the inner support ring can also be clamped by the moving disk 6 and the fixed disk 5 to prevent the packaging paper bag from running off during winding. And through the arrangement of the plurality of moving disks 6, an inner support ring is fixed between the moving disks 6 and the moving disks 6, so that multiple groups of packaging paper bags can be wound simultaneously, improving the winding efficiency;

[0026] The support rods 8 are movably arranged inside the corresponding arc-shaped grooves 7. A plurality of limit pieces 10 are movably arranged at both ends of the fixed disk 5.

Then install the moving disk 6 on the rotating shaft 4, insert the support rods 8 into the corresponding arc-shaped grooves 7, and then clamp the fixed clamp 11 outside the rotating shaft 4. Rotate the moving disk 6, so that the moving disk 6 drives the arc-shaped groove 7 to rotate, and the arc-shaped groove 7 then drives the support rod 8 to rotate. Under the limitation of the limiting piece 10, the support rod 8 moves, so that the support rod 8 drives the anti-slip layer 9 to contact the inner wall of the inner support ring, thereby fixing the inner support ring. Then push the moving disk 6 towards the fixed disk 5, so that the moving disk 6 and the fixed disk 5 clamp the inner support ring. Then, through the fixed clamp 11, squeeze the moving disk 6, so that the moving disk 6 squeezes the inner support ring to fix the inner support ring. Then start the driving motor 3, so that the driving motor 3 drives the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the fixed disk 5 and the moving disk 6 to rotate, and then the support rod 8 rotates to drive the inner support ring to wind the packaging paper bag;

[0031] When it is necessary to increase the number of inner support rings, add the moving disk 6 and the fixed clamp 11, and clamp another inner support ring with two moving disks 6.
