Description

Technical Field

[0001] The utility model belongs to the field of breathable film edge cutting, and particularly relates to a breathable film edge cutting mechanism. Background Art

[0002] The breathable film trimming mechanism is mainly used to accurately cut and trim the edges of breathable films. During the production process of breathable films, due to various reasons (such as unevenness in the extrusion process, mold design errors, etc.), the edges of the film may appear irregular or uneven. Through the breathable film trimming equipment, these irregular edges can be effectively removed, giving the breathable film a more neat and smooth appearance.

[0003] The prior art has specially developed some mechanisms for breathable film edge trimming to improve the neatness of the breathable film. For example, the Chinese patent with the authorization announcement number "CN212825602U" announced "A breathable film production edge trimming and rolling device". The breathable film is rolled on the surface of the film rolling rod by rotating the film rolling rod. The movement of the breathable film drives the knife holder rod to rotate. The knife holder rod drives the cutting knife to rotate to cut the two sides of the breathable film. As time goes by, the film roll on the surface of the film rolling rod becomes thicker and thicker. The film roll pushes the knife holder rod upward, and the knife holder rod drives the slider to move upward on the surface of the slide rod. The gravity of the knife holder rod makes the knife holder rod always stick to the upper end of the breathable film roll, so that it can automatically adjust its position according to the thickness of the film roll, making the edge trimming process more convenient.

[0004] Although the knife holder can cut off the edge of the breathable film to achieve the trimming effect, and the film roll can also effectively collect the breathable film to make the breathable film neater, the knife holder and the film roll are fixed inside the support seat for a long time. This will reduce the sharpness of the knife under the long-term use of the knife. If it continues to be used, it will lead to incomplete cutting of the breathable film. The breathable film will be pulled out and re-trimmed, which will increase the workload. When a certain amount of film roll is collected, it cannot be rolled up again, which will reduce efficiency and increase the workload of workers, which is very inconvenient to use.

A connecting plate 5 is fixedly installed on the ends of the sliding rods 25 and the sliding rod 1 24 away from the circular opening 31. A micro motor 9 is fixedly installed on the side of the connecting plate 5 away from the fixed plate 4. The output shaft of the micro motor 9 is fixedly installed with a mounting block 10, and the mounting block 10 is sleeved inside the sleeve block 11.

[0030] refer to Figures 2 to 7 , one end of the cutter 17 is integrally formed with an external thread 32, and the interior of the cutter 17 is provided with an internal thread 23, so that the cutter 17 can be easily removed for replacement later. Because the sharpness of the cutter 17 will be reduced after a long period of use, if the cutting is continued, the breathable film will be incompletely cut, so that the worker needs to remove the breathable film from the reel 13 to continue cutting. Due to long-term wear, the cutter 17 will cause wrinkles on the edge of the breathable film when cutting, resulting in the need to destroy the entire breathable film, which will increase the cost and increase the workload of the workers. A spring 30 is fixedly installed at one end of the slide bar 24, and the end of the spring 30 away from the slide bar 24 is fixedly installed inside the circular opening 31, so that the micro motor 9 can be pulled to separate the micro motor 9 from the rotating rod 28, so that the reel 13 sleeved with the outer ring of the rotating rod 28 can be disassembled, which can improve efficiency and increase mobility.

[0031] refer to Figures 2 to 8The driving screw 12 and the rotating screw 23 are fixedly mounted on the bearing inside the support seat 3 at one end away from the cutter 17, and the two ends of the rotating rod 28 are fixedly mounted with bearings, so that the driving screw 12 and the rotating screw 23 can achieve rapid rotation, so that the cutter 17 can stably cut off the edge material of the breathable film, and can also fix the cutter 17, so that the cutter 17 can rotate to improve the sharpness of the cutter 17, and one end of the rotating rod 28 close to the installation box 14 is connected to the limiting plate 27 by a thread, and the limiting plate 27 is threadedly connected to one side of the reel 13. By twisting the limiting plate 27, the reel 13 can be kept consistent with the rotating rod 28, and the reel 13 will not swing left and right on the outer circle of the rotating rod 28. In this way, the neatness of the breathable film can be improved when it is rolled up, and it can also ensure that the breathable film will not be entangled. The first screw 7 is connected by The connecting port 36 is threadedly connected to the threaded hole 34 inside the movable plate 1, and a baffle is fixedly installed on the end of the rotating rod 28 away from the cutter 17, so as to prevent the rotating rod 28 from slipping or falling, and the rotating rod 28 can be kept rotating inside the support seat 3, and the position of the rotating rod 28 can be effectively limited, so that the cutter 17 will not move. Rotating shafts 39 are fixedly installed on both sides of the inner wall of the rectangular opening 38, and a pulley 8 is fixedly installed on the end of the rotating shaft 39 away from the inner wall of the rectangular opening 38, which can effectively assist the reel 13 to recover the cut breathable film.
