DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, a PVC color film protection device comprises a bottom frame 2 and a top frame 3, the top frame 3 is rotatably installed on the edge side of the bottom frame 2 by hinges, and the top frame 3 is attached to the surface of the bottom frame 2, both ends of the bottom frame 2 and the top frame 3 are constructed with arc grooves, and a color film disk rotating component for controlling the rotation of the color film roll is clamped between the arc grooves, the outer periphery of the top frame 3 is installed with symmetrically arranged limit frames 7, and the bottom of the limit frames 7 extends to the surface of the bottom frame 2, and color film linear cutting components are installed between the limit frames 7, a color film support strip 14 is fixed to the top of the outer periphery of the bottom frame 2, and the top of the color film support strip 14 is flush with the top of the bottom frame 2, the bottom of the top frame 3 is constructed with a color film pulling-out groove 13 for the color film to pass through, the bottom of the bottom frame 2 is fixed with a base 1, and the base 1 is symmetrically arranged, and the base 1 can prevent the bottom frame 2 and the top frame 3 from rolling.

[0025] In order to facilitate the control of the rotation of the color film roll so as to release the color film when in use, the color film disk rotating component includes a chuck 4 clamped between the arc grooves, and an annular clamping groove 41 is constructed at the center of the outer periphery of the chuck 4. A color film disk rotating shaft 5 is rotatably installed between the chucks 4 through bearings. One end of the color film disk rotating shaft 5 extends to the outside of the chuck 4, and a handle ring 6 is fixed to one end of the color film disk rotating shaft 5 located on the outside of the chuck 4. The manufactured color film roll is sleeved and fixed on the outer periphery of the color film disk rotating shaft 5. The color film disk rotating shaft 5 is not only convenient for lifting the color film roll, but also convenient for driving the color film roll to rotate to release the wound color film. The length of the color film pulling groove 13 is greater than the inner side spacing of the chuck 4, which can avoid scratching of the two sides of the color film with the top frame 3.

[0026] In order to facilitate the smooth cutting of the pulled out color film and facilitate subsequent use, the color film linear cutting component includes a limit groove 8 in the internal structure of the limit frame 7, and a limit slider 9 is slidingly arranged inside the limit groove 8, and a color film lower pressure plate 10 that can move in accordance with the periphery of the top frame 3 is fixed between the side walls, and a color film cutting groove 11 is arranged inside the color film lower pressure plate 10, and a handle 12 for driving the color film lower pressure plate 10 to move is fixed on the surface of the color film lower pressure plate 10.

[0027] It should be noted that the utility model is a PVC color film protection device. The produced color film is wound around the outer periphery of the color film disc shaft 5. The color film disc shaft 5 is hoisted by a hoisting device to move the color film roll to between the chucks 4, and then the position of the chucks 4 is adjusted to align the chucks 4 with the arc groove of the bottom frame 2. Then the color film disc shaft 5 is separated from the hoisting device, and the top frame 3 is rotated and attached to the surface of the bottom frame 2. During transportation and use, the bottom frame 2 and the top frame 3 provide better protection for the color film roll to prevent the color film from being exposed to the sun and scratches caused by mutual friction. When in use, one end of the color film is removed from the color film. The color film is pulled out from the pull-out groove 13, and the handle ring 6 is rotated according to the need of use to drive the color film disk shaft 5 and the color film reel to rotate, thereby releasing a sufficient amount of color film. When the release is completed, the color film lower pressure plate 10 is pulled downward to press the color film tightly between the color film lower pressure plate 10 and the color film support strip 14. At this time, the color film cutting groove 11 is vertical to the color film surface. After the cutter is inserted into the color film cutting groove 11 and slid horizontally, the color film can be cut flatly. The end of the color film can also be pressed tightly by the color film lower pressure plate 10 and the color film support strip 14 to prevent the color film from shrinking into the bottom frame 2, so as to facilitate the subsequent use to find the end of the color film.
