[0021] In this example, the horizontal bolts 4 are symmetrically distributed about the center of the support plate 2. The horizontal bolts 4 fit tightly against the inner wall of the track window 6. The length of the track window 6 is greater than half of the overall height of the support plate 2. The above-mentioned structural design enables the sleeve plate 3 to slide relative to the track window 6 and the horizontal bolts 4, ensuring that the sleeve plate 3 can slide vertically on the support plate 2 to adjust a sufficient distance.

[0022] The bottom end of the blocking rod 8 is threadedly connected to the hole opened at the end of the unloading plate 7. The front view shape of the unloading plate 7 is "L" shape. A 1 / 4 arc surface is provided at the end of the unloading plate 7 away from the blocking rod 8. The above structural design enables the blocking rod 8 to be easily disassembled and installed, and facilitates the transfer and positioning of the winding film roll.

[0023] The horizontal threaded rod 10 is threadedly connected to the movable plate 12, and support rods 13 are installed at equal intervals on the top surface of the movable plate 12. The above-mentioned structural design enables the horizontal threaded rod 10 to drive the movable plate 12 to move by utilizing the threaded connection relationship when rotating, and the movable plate 12 can push the support rod 13, and the support rod 13 rotates to stably drive the sleeve plate 3.

[0026] Working principle: When using this device, first install a suitable number of counterweights 15 on the vertical threaded rod 14 according to the weight of the winding film roll to be transferred, then move the entire device close to the unloading position of the winding film reel, remove the blocking rod 8 from the unloading plate 7, and Figure 2 The positioning nut 5 in the sleeve plate 3 rotates away from the surface of the sleeve plate 3, and the symmetrically distributed servo motors 9 are started to control the servo motors 9 to drive the horizontal threaded rods 10 to rotate synchronously. The horizontal threaded rods 10 are driven by the threaded connection relationship. Figure 2 The movable plate 12 slides horizontally to the left along the limiting groove 11, and the movable plate 12 pushes the bottom end of the support rod 13 to move left during the left sliding process, and the support rod 13 rotates to push the sleeve plate 3 to slide vertically upward along the support plate 2;

[0027] The end of the unloading plate 7 on the top of the sleeve plate 3 is aligned with the bottom of the winding film roll to be unloaded on the winding film winding device, and the servo motor 9 is controlled to stop working to lock the horizontal threaded rod 10. The horizontal threaded rod 10 uses the thread self-locking to fix the movable plate 12, and the positioning nut 5 is rotated to squeeze the sleeve plate 3 and the support plate 2 to fit and fix it, so that the winding film roll can be pushed and transferred to the unloading plate 7, and the winding film is rolled to Figure 2 The right end of the middle unloading plate 7 is pushed, and then the blocking rod 8 is installed and reset to block the wrapping film roll. The moving device as a whole moves away from the wrapping film winding device to complete the unloading of the wrapping film roll. This is the working principle of the automatic unloading device after the wrapping film is wound.
