[0026] See also Figures 1 to 4 , the utility model provides a technical solution: a composite plastic film wrapping machine, comprising a wrapping machine base 1 and a plastic film support frame 2, wherein the outer side of the wrapping machine base 1 is slidably connected to the plastic film support frame 2;

[0027] The limiting structure 7 is inserted into the limiting slot 6 provided on one side of the winding machine base 1, and plays the role of limiting clamping and fixing in the winding machine base 1;

[0029] In actual use, the plastic film support frame 2 of the plastic film wrapping machine can be adjusted in height according to plastic films of different sizes to ensure that the plastic film remains stable on the plastic film support frame 2 and reduce the breakage of the plastic film caused by shaking. The wrapping machine can adjust the distance between the plastic film and the object according to the size of the wrapped object to improve the stability during winding. If the distance between the plastic film and the object is large, the plastic film will be over-stretched and there is a risk of breakage. If the distance between the plastic film and the object can be adjusted in time, this risk can be well avoided. Example

[0030] On the basis of the first embodiment, the winding machine base 1 includes a metal bottom plate 3, a slide groove 4, a winding rotating plate 5, a limiting slot 6 and a limiting structure 7. The top of the metal bottom plate 3 is provided with a slide groove 4, and the winding rotating plate 5 is installed in the slide groove 4. A limiting slot 6 is provided on one side of the metal bottom plate 3. The limiting slot 6 is provided with several groups.

[0033] Before winding, the sliding distance of the winding rotating plate 5 in the slide groove 4 can be adjusted according to the size of the goods. After determining the specific position of the winding rotating plate 5, the two sets of limiting structures 7 are respectively inserted into the corresponding limiting slots 6 to limit the two sides of the winding rotating plate 5, and the position of the plastic film winding rod 9 can be adjusted by adjusting the position of the sliding plate 8 to prevent the goods from being too large and the plastic film winding rod 9 from blocking the goods during winding. Example

[0034] On the basis of the first embodiment, the limiting structure 7 includes a limiting rod 10, a fitting groove 11, a support pad 12, a spring washer 13, a pressing plate 14 and an insertion rod 15.

[0037] The fitting grooves 11 of the two sets of limiting structures 7 limit the bottom of the winding rotating plate 5, thereby reducing the shaking and misalignment of the winding rotating plate 5 during rotation, thereby improving the overall stability;

[0038] The plastic film winding rod 9 includes a limiting rod 16, an upper limiting plate 17, an anti-falling limiting plate 18, a lower limiting plate 19, a second limiting rod 20 and a spring 21.
