Description

Technical Field

[0001] The utility model relates to the technical field of film processing, in particular to a film segment processing device. Background Art

[0002] Thin films are thin metal or organic layers ranging in thickness from a single atom to several millimeters. They are widely used in industries such as electronics, machinery, and printing. Electronic semiconductor devices and optical coatings are the primary applications of thin film technology. Film materials can be categorized by their raw materials into polyethylene film, polypropylene film, polyvinyl chloride film, and polyester film. Film materials can be categorized by their intended use into packaging film, breathable film, water-soluble film, and film with piezoelectric properties. Film materials can be categorized by their forming method into blown film, cast film, and calendered film. Existing films require segmented processing during production to meet the needs of downstream processes.

[0003] In the prior art, publication number "CN109607279A" discloses a film length segmentation control device and its processing technology, which uses a dual-axis motor to simultaneously drive the first rotating rod and the second rotating rod to rotate, and transmits and cuts the film to perform segmented cutting, so as to achieve the effect of cutting once the first roller rotates one circle. There is no need to use PLC control, the equipment is simple to use and operate, which reduces production costs and ensures cutting accuracy. It solves the problem that the existing film segmentation processing equipment is relatively expensive and mostly adopts PLC programming control. Although this has high accuracy, it is relatively expensive, which is not conducive to the use of small processing plants and increases the cost of equipment use.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] At present, the film needs to be processed during the production process, which includes segmenting the film. Therefore, in the segmentation process, it is necessary to use a cutter to cut the film. However, in the cutting process, when the film is in a relaxed state, the cut end surface of the cut film is uneven, which can easily affect the quality of the film. As in the case mentioned above, the cut film falls into the collection box by its own weight, but since the weight of the film is very light, it is easy to cause the cut film to fall outside the collection box.

[0031] Example 2:

[0032] On the basis of Example 1, the cutting assembly is described in detail. The cutting assembly includes a driving mechanism and a segmenting mechanism. The driving mechanism includes a pulley 13, a rotating shaft 14 and a rotating shaft 2 18. The pulley 13 is fixedly mounted on the output shaft of the motor 14. The rotating shaft 14 is rotatably mounted on the side plate 12. The side plate 2 17 is fixedly mounted on the bottom plate 1 and is located on the right side of the side plate 2. The rotating shaft 2 18 is rotatably mounted with the rotating shaft 2 18. The rotating shaft 14 is fixedly mounted with pulleys 2 15 and 3 16. The rotating shaft 2 18 is fixedly mounted with a pulley four 19 and a cam 20, the pulley one 13 is driven by the belt one and the pulley two 15, the pulley three 16 is driven by the belt two and the pulley four 19, and the output shaft of the motor two 8 is rotated to drive the pulley one 13 on the rotating shaft two 18 to rotate, and the belt one drives the pulley two 15 to rotate, thereby driving the pulley three 16 on the rotating shaft one 14 to rotate, and then driving the pulley four 19 to rotate through the belt two, thereby driving the cam 20 on the rotating shaft two 18 to rotate.

[0033] The segmentation mechanism includes a support plate 5 fixedly mounted on the side plate 2, a lifting rod 22 slidably mounted on the support plate 5, a lifting plate 21 fixedly mounted on the top end of the lifting rod 22, a spring 24 fixedly mounted on the lower end surface of the lifting plate 21, and the cutter 23 can be restored to its original position by utilizing the elastic performance of the spring 24. The end of the spring 24 away from the lifting plate 21 is fixedly mounted on the upper end surface of the support plate 5, and the bottom end of the lifting rod 22 is fixedly mounted with a cutter 23 for cutting the film body 12.

[0034] Example 3:

[0035] On the basis of Example 1, in order to ensure that the film is in a flat state when the cutter 23 is cutting the film, a stretching component is used to achieve this function. The side end face of the cutter 23 is provided with a stretching component, which includes a mounting block 25 mounted on the cutter 23. The mounting block 25 is provided with a limiting groove, and the connecting shaft 26 and part of the rotating plate 27 are located inside the limiting groove. The limiting groove can be used to ensure that the rotating plate 27 is in an inclined state, ensuring that the pressure roller 29 on the rotating plate 27 can be in a tensioning and stretching effect when rotating. The mounting block 25 is rotatably mounted with a connecting shaft 26, and the rotating plate 27 is fixedly mounted on the connecting shaft 26.

A pressure roller 29 is rotatably mounted inside the rotating plate 27, and a side end face of the pressure roller 29 is provided with a protective pad 30. The material used for the protective pad 30 is rubber. The protective pad 30 made of rubber can prevent the pressure roller 29 from causing damage to the film.

[0036] Working principle:

[0037] When in use, two motors 4 are used to drive two conveying rollers 3 to rotate respectively, and the conveying rollers 3 can be used to convey the film. When one of the conveying rollers 3 rotates, it will drive the pulley 13 to rotate. The pulley 13 is driven by the belt 1 and the pulley 2 15, and the pulley 3 16 is driven by the belt 2 and the pulley 4 19. The output shaft of the motor 2 8 rotates, which can drive the pulley 13 on the rotating shaft 2 18 to rotate. The belt 1 drives the pulley 2 15 to rotate, thereby driving the pulley 3 16 on the rotating shaft 14 to rotate, and then the belt 2 drives the pulley 3 16 on the rotating shaft 14 to rotate. The pulley 19 is driven to rotate, thereby driving the cam 20 on the second rotating shaft 18 to rotate. Through the rotation of the cam 20, the cam 20 presses down the lifting plate 21. The descent of the lifting plate 21 drives the lifting rod 22 to descend. The cutter 23 on the lifting rod 22 can cut the film on the positioning block 7. When the cam 20 rotates a certain angle, the lifting plate 21 is slowly raised by the elasticity of the spring 24. The rotation of the cam 20 and the elasticity of the spring 24 can make the cutter 23 in a state of lifting and lowering back and forth, and the cut films are of the same length.

[0038] When the cutter 23 is not in contact with the film, the pressure roller 29 on the cutter 23 will press on the film. When the cutter 23 descends, the pressure roller 29 will expand outwards through the rotating plate 27 by utilizing the reaction force. While expanding, the slack film can be stretched to keep it in a taut state, which can effectively ensure that the cutter 23 does not have an uneven cut when cutting the film.

[0039] While the film is being cut, the electric push rod 32 is used to drive the U-shaped frame 33 to move to the tail end of the film. By starting the cylinder 34, the clamping plate 35 can be driven to clamp the tail end of the film, and then the electric push rod 32 is used to pull it to the entrance of the collection box 11, which can effectively prevent the cut film from falling.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
