[0033] Referring to Figure 1 , two third supporting plates 14 are fixedly connected to the upper surface of the bottom plate 1 and arranged vertically, two groups of parallelly arranged guide rollers 15 are rotatingly connected between the two third supporting plates 14, and the plastic roll film is connected to the winding drum 7 by penetrating through each group of guide rollers 15, so that the stability of the winding drum 7 in winding the plastic roll film can be improved.

[0034] Referring to Figure 1 and Figure 4The top end of the second support plate 10 is fixedly connected with a second L-shaped plate 16 on one side of the first L-shaped plate 11, and a plurality of springs 17 are fixedly connected with the lower surface of the second L-shaped plate 16 at equal intervals. The end of the spring 17 away from the second L-shaped plate 16 is fixedly connected with a U-shaped frame 18, and a pressure roller 19 for pressing the plastic film onto the double-sided adhesive tape 8 is rotatably connected with the inner wall of the U-shaped frame 18. The pressure roller 19 is pressed down by the spring 17, so that when the winding drum 7 winds the plastic film, the plastic film is attached to the winding drum 7.

In the winding process, the spring 17 presses the pressure roller 19 downward, so that the plastic film is attached to the winding drum 7 when the winding drum 7 winds the plastic film. When the winding drum 7 is wound, the stepping motor 3 is started to rotate by one hundred and eighty degrees, and the rotating plate 5 is driven to rotate by one hundred and eighty degrees, so that the wound winding drum 7 is exchanged with the new winding drum 7, and the new winding drum 7 is located below the plastic film. At the same time, the winding drum 7 is separated from the pressure roller 19, the spring 17 rebounds to press the pressure roller 19 downward, the pressure roller 19 presses the plastic film downward, the lower surface of the plastic film is pressed onto the new winding drum 7, and the plastic film is adhered to the double-sided adhesive tape 8. Then, the cutting knife 13 is lowered by starting the electric telescopic rod 12, the plastic film connected to the wound winding drum 7 is cut, the new winding drum 7 continues to wind, and the problem that the work efficiency is reduced due to the need to stop and replace the new winding drum 7 and the plastic film cannot be directly replaced to the new winding drum 7 is avoided.

[0040] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
