[0003] In the actual processing of plastic films, the plastic films need to be folded to facilitate subsequent processing operations. However, the existing plastic film folding often requires the cooperation of machines and manual labor, which is inconvenient and needs to be improved. Utility Model Content

[0004] In order to facilitate the folding of a plastic film, the present application provides a plastic film folding device.

[0027] The present application discloses a plastic film folding device. Figure 1 , including a frame 1, the frame 1 is provided with a mounting rod 2, the upper end surface of the mounting rod 2 is provided with a mounting block 3, the mounting block 3 is rotated with a rotating rod 4, the axis of the rotating rod 4 is parallel to the length direction of the mounting rod 2, the rotation axis of the rotating rod 4 is its own axis direction, and the rotating rod 4 is used to resist the lower end surface of the plastic film 13.

[0028] The mounting rod 2 is provided with a stopper 5, which is located at one end of the mounting rod 2 provided with the mounting block 3, and the stopper 5 abuts against the side of the rotating rod 4 away from the mounting rod 2, and the stopper 5 is used to limit the movement of the plastic film 13 along the axis direction of the rotating rod 4. In the present application, the stopper 5 includes a stopper block 51 and a stopper bolt 52, and the stopper block 51 is provided with a clearance groove 6, and the clearance groove 6 is located on the side of the stopper block 51 close to the mounting rod 2, and the bottom of the clearance groove 6 is used to abut against the rotating rod 4, and the stopper block 51 is used to abut against the plastic film 13. In actual use, there are two stopper blocks 51, and the two stopper blocks 51 are respectively located on both sides of the plastic film 13, and the stopper blocks 51 abut against the side wall of the plastic film 13, and the stopper blocks 51 are used to limit the movement of the plastic film 13 along the axis direction of the rotating rod 4. The stopper block 51 is provided with an extension plate 7, and the extension plate 7 is located on the side of the side wall of the stopper block 51 close to the mounting rod 2, and the stopper bolt 52 passes through the extension plate 7 and is embedded in the mounting rod 2. In other embodiments, a limit pin may also be provided, the limit pin passing through the extension plate 7 and embedded in the upper end surface of the mounting rod 2 .

[0029] The mounting rod 2 is provided with a folding portion 8, which is used to abut against the plastic film 13 so that the plastic film 13 is folded in half along its midline. The folding portion 8 includes a folding rod 1 81 and a folding rod 2 82. The folding rod 1 81 extends downward in a direction away from the mounting rod 2 and extends toward a direction close to the folding rod 2 82. The folding rod 2 82 extends downward in a direction away from the mounting rod 2 and extends toward a direction close to the folding rod 1 81. One end of the folding rod 1 81 away from the mounting rod 2 is connected to one end of the folding rod 2 82 away from the mounting rod 2.

[0030] In the present application, the folding rod 1 81 and the folding rod 2 82 are symmetrically arranged, and the acute angle between the folding rod 1 81 and the mounting rod 2 is consistent with the acute angle between the folding rod 2 82 and the mounting rod 2. When the plastic film 13 hits the folding rod 1 81 and the folding rod 2 82, the end of the folding rod 1 81 away from the mounting rod 2 and the end of the folding rod 2 82 away from the mounting rod 2 hit the plastic film 13 so that the plastic film 13 is folded along its own midline.

[0031] The folding rod 1 81 is provided with a stretching frame 9, and the stretching frame 9 connects the folding rod 1 81 and the folding rod 2 82.

[0032] The implementation principle of a plastic film folding device in an embodiment of the present application is as follows: in actual use, the plastic film 13 moves along the extension direction of the folding portion 8 through the rotating rod 4, and bends along its own center line when it moves to the connection between the folding rod 1 81 and the folding rod 2 82, thereby completing the folding of the plastic film 13.

[0033] Embodiment 2:

[0034] Reference Figure 3 The difference between this embodiment and embodiment 1 is that the folding portion 8 is provided with a rotating groove 11, and the rotating groove 11 is located at the end of the folding portion 8 away from the mounting rod 2. The rotating groove 11 is formed by splicing the groove at the end of the folding rod 1 81 away from the mounting rod 2 and the groove at the end of the folding rod 2 82 away from the mounting rod 2. A rotating bead 12 is detachably provided at the bottom of the rotating groove 11, and the rotating bead 12 rotates on the groove wall of the rotating groove 11, and the rotating bead 12 is used to resist the plastic film 13.

[0035] The implementation principle of Example 2 is: in actual use, when the plastic film 13 moves to the connection between the folding rod 1 81 and the folding rod 2 82, the rotating ball 12 contacts the plastic film 13 and causes the plastic film 13 to bend along its own center line, thereby completing the folding of the plastic film 13, and the rolling of the rolling ball also reduces the friction of the plastic film 13 when it passes.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
