[0002] During the production process of films, the films will be cut according to the required width. The cut film edge materials are still in a brand-new state and not contaminated. Therefore, the film edge materials will be recycled. Since the entire film production is in a circular system, the recycling of films will use a crushing mechanism for crushing and recycling. Since the crusher has a limited width range for crushing films and cannot handle the crushing of large edge materials, the width of film cutting will be restricted during film cutting to cope with the width range of the cut edge materials, resulting in waste of films. At the same time, secondary cutting is required to complete the processing of the required film size. Summary of the Utility Model

[0016] Embodiment

[0017] Please refer to Figure 1, the present utility model proposes an off-line recycling device for casting films, which includes a frame body 1, compression rollers 2 for compressing the film, a shrinking member 3 and a cutting member 4. Every two compression rollers 2 are rotatably installed on the frame body 1 in a group. The shrinking member 3 is installed on the frame body 1 and guides the film to converge between a group of compression rollers 2. Each group of compression rollers 2 guides the compressed film to the cutting member 4 for cutting. In the present utility model, the film edge material is cut and then transferred to the recycling device through a guide roller 5. When the edge material passes through the shrinking member 3, since there are holes 31 in the shrinking member 3, the film will gather together when passing through the holes 31, and it will converge in width. When the film converges, it will pass through the compression rollers 2 for pressing. The distance between each group of compression rollers 2 is greater than the thickness of the film, so as to avoid the situation that the compressed film becomes wider again. At this time, after compression, the film will form a rod shape with a certain hardness. Next, it will continue to pass through the shrinking member 3 and undergo the process of gathering and compression again. The holes 31 of the shrinking members 3 sequentially installed on the frame body 1 gradually decrease, and the distance between each group of shrinking rollers sequentially increases, so that the film can gradually form a cylindrical shape and be cut into segments for recycling, avoiding the situation that the film is too wide to be recycled.

[0018] In a specific embodiment, referring to Figure 1 , multiple groups of compression rollers 2 are installed on the frame body 1. One side of each group of compression rollers 2 is provided with a shrinking member 3 for guiding the film between a group of compression rollers 2.

The line width of the holes 31 is less than the width of the film and greater than the gap between a group of compression rollers 2. The holes 31 on the shrinking member 3 are used to gather the film. When the film passes through the holes 31, the wider film will gather together and shrink in width, and then be compacted by the compression rollers 2. At the same time, the holes 31 in the present utility model are round holes, and the edges of the holes 31 can also be provided with arcs or guide wheels to reduce friction and avoid film breakage.

[0020] In a specific embodiment, referring to Figure 1 , multiple guide rollers 5 are also installed on the frame body 1, and the film is guided in an S shape between the guide rollers 5. The guide rollers 5 on the frame body 1 are used to guide the compressed film to the cutting member 4 for cutting into segments.

[0021] In a specific embodiment, referring to Figure 1, the cutting member 4 includes a pressure roller 41, a lifting frame 42 and a cutter 43. The lifting frame 42 is installed on the frame body 1, the pressure roller 41 is rotatably installed on the frame body 1 and drives the compressed film, and the cutter 43 is installed on the lifting frame 42 and cuts the film. In the present utility model, there are three groups of pressure rollers 41. According to the guiding direction of the film, they are the first group of pressure rollers 41, the second group of pressure rollers 41 and the third group of pressure rollers 41 in sequence. The first group of pressure rollers 41 and the second group of pressure rollers 41 are used to guide the compressed film, and the second group of pressure rollers 41 and the third group of pressure rollers 41 are used to fix the film, facilitating the cutter 43 to control the cutting of the film through the lifting frame 42.

[0022] In a specific embodiment, referring to Figure 1 , there are multiple pressure rollers 41, and every two pressure rollers 41 form a group. The cutter 43 is located between two groups of pressure rollers 41.
