A fixed plate 12 has a screw 13 rotatably connected to its surface near the center. A U-shaped plate 14 is threaded onto the surface of the screw 13. The other end of the screw 13 passes through the fixed plate 12 and is rotatably connected to its bearing. A drive motor 15 is fixedly connected to the surface of the fixed plate 12. The output end of the drive motor 15 is fixedly connected to one end of the screw 13, which enables the drive motor 15 to drive the screw 13 to rotate. The rotation of the screw 13 can drive the U-shaped plate 14 to move. A placement hole 17 is opened on the top of the U-shaped plate 1. Vertical plates 21 are fixedly connected to the top of the machine body 1 and near both sides of the edge. A round rod 22 is embedded in the center of the vertical plate 21 and rotatably connected to its bearing. A stud 24 is fixedly connected to one end of the round rod 22. A cross plate 25 is threaded onto the surface of the stud 24. Rotating the cross plate 25 can disengage it from the surface of the stud 24, thus facilitating the installation and removal of the cling film roll.

[0017] like Figure 1 As shown, a support plate 11 is fixedly connected to one end of the body 1 and near the bottom. Support legs 2 are fixedly connected to the bottom of both the body 1 and the support plate 11. With the above arrangement, the support legs 2 can support the bottom of the body 1 and the support plate 11.

[0018] like Figure 2 As shown, a limiting rod 16 is slidably connected through one end of the U-shaped plate 14 and near both sides. Both ends of the limiting rod 16 are fixedly connected to the surface of the fixed plate 12. Through the above arrangement, the limiting rod 16 can limit the U-shaped plate 14.

[0019] like Figure 4As shown, a second electric push rod 18 is embedded and fixedly connected to the top of the support plate 11 and below the placement hole 17.

Through the above arrangement, the plastic wrap roll can be conveniently rotated.

[0022] The device's operation and working principle are as follows: A roll of cling film is fitted onto one of the round rods 22. A cross plate 25 is then fitted onto the stud 24 and rotated, allowing the first and second turntables 23 and 26 to clamp and fix the cling film roll. One end of the cling film can then pass through the surfaces of the first and second rotating cylinders 5 and 9, and be driven by the first electric push rod 10. The first electric push rod 10 pushes the sliding rod 8 to slide within the sliding hole 7. The sliding of the sliding rod 8 pushes the cling film on the surface of the second rotating cylinder 9, allowing for adjustable tension of the cling film. For smaller packages, the packaging box to be packaged can be placed inside the placement hole 17. Then, the drive motor 15 drives the screw 13 to rotate. The rotation of the screw 13 moves the U-shaped plate 14 into the spacer 3. The spacer 3 can then package the packaging box below. After packaging, the screw 13 can be rotated in the opposite direction. The rotation of the screw 13 can disengage the U-shaped plate 14 from the spacer 3. Then, the second electric push rod 18 can push the push plate 19 to rise, which facilitates the removal of the packaged box after packaging.
