[0024] Example

[0025] like Figure 1-3As shown, this embodiment provides a film loading and rolling mechanism, including a film loading frame 1, the upper part of which is rotatably connected to a film loading roller 2. In this embodiment, the film loading roller 2 adopts a screw-type large roller in the prior art for film loading, which is simple to load and has a stable structure. The film loading frame 1 is provided with a brake assembly 3 at a position below the film loading roller 2, and the upper part of the film loading frame 1 is provided with a film rolling frame 41, and at least one film rolling cylinder 42 is rotatably connected to the film rolling frame 41. The film roll to be packaged is installed on the film loading roller 2, and then the film passes through the brake assembly 3 and the film rolling cylinder 42, and the film is pulled by the brake assembly 3 and the film rolling cylinder 42 to balance the film tension, and the brake assembly 3 can make the film turn sharply and stop steadily, and will not stretch and deform the film. After passing through the film rolling cylinder 42, the film enters the downstream mechanism to package the box.

[0026] Specifically, the film loading frame 1 includes a pillar 11, and the pillar 11 is a rectangular parallelepiped structure. The first mounting side plate 12 and the second mounting side plate 13 are respectively fixedly installed on the opposite sides of the top of the pillar 11 by bolts. One end of the film loading roller 2 passes through the first mounting side plate 12 and the second mounting side plate 13. The film loading roller 2 is rotatably connected to the first mounting side plate 12 and the second mounting side plate 13. The film rolling frame 41 is fixedly connected to the upper part of the first mounting side plate 12, and the brake assembly 3 is arranged at the lower part of the first mounting side plate 12. The installation structure of the film loading roller 2 and the brake assembly 3 is more stable through the two first mounting side plates 12 and the second mounting side plates 13 arranged at a certain distance. The traditional film loading roller 2 is only installed through a single mounting plate, lacks a supporting structure, and causes the structure to be unstable.

[0027] Specifically, the brake assembly 3 includes a brake support 31 rotatably connected to the first mounting side plate 12, one end of the brake support 31 passes through the first mounting side plate 12 and the second mounting side plate 13, and is rotatably connected to the second mounting side plate 13, a brake swing arm 32 is provided on the brake support 31, one end of the brake swing arm 32 can swing with the brake support 31 as the axis, and a brake roller 33 is rotatably connected to the surface of the brake swing arm 32. In this embodiment, the number of brake rollers 33 is two.

[0028] Among them, the surface bolts of the first mounting side plate 12 are fixedly connected with a brake adjusting seat 34, and the brake adjusting seat 34 is threadedly connected with an adjusting bolt 35, the top of the adjusting bolt 35 is connected with a first brake band fixing plate 36, and the first brake band fixing plate 36 is fixedly connected with a brake band 37 by bolts, and the brake band 37 is made of wear-resistant material, and a brake wheel 38 is arranged on the film loading drum 2, and the brake band 37 is arranged to abut against the upper part of the brake wheel 38, and the end of the brake band 37 away from the adjusting bolt 35 is fixedly connected with a second brake band fixing plate 39, and the second brake band fixing plate 39 is fixedly connected with a brake tension spring 310, and the end of the brake tension spring 310 away from the second brake band fixing plate 39 is connected to the brake swing arm 32. When the film is pulled and moved by the two brake rollers 33, the brake swing arm 32 is driven to swing, and the brake spring 310 is stretched at this time, and buffered by the brake spring 310. When the film swings to a certain extent, the brake assembly 3 can be used to make a sharp turn and stop steadily to prevent the film from being stretched and deformed; and the height of the adjusting bolt 35 can be changed by rotating the adjusting bolt 35, thereby changing the position of the brake belt 37, adjusting the tension of the brake spring 310, and thus adjusting the overall tension.

[0029] Furthermore, a brake limiting plate 51 is provided at a position of the first mounting side plate 12 below the brake swing arm 32, and a brake limiting pad 52 is fixedly connected to one end of the brake limiting plate 51 close to the brake swing arm 32. By providing the brake limiting pad 52 below the brake swing arm 32, the travel of the brake swing arm 32 is limited to prevent deformation caused by excessive stretching of the film.

[0030] Furthermore, the film rolling frame 41 includes a first connecting plate 411 and a second connecting plate 412, one end of the first connecting plate 411 is connected to the first mounting side plate 12, the first connecting plate 411 and the second connecting plate 412 are connected through the film rolling cylinder 42, and the two ends of the film rolling cylinder 42 are respectively rotatably connected to the first connecting plate 411 and the second connecting plate 412. In this embodiment, there are three film rolling cylinders 42, which are arranged in parallel, and the film is pulled by two brake rollers 33 and three film rolling cylinders 42, so that the film tension is balanced and the film feeding is stable.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
