Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plated film processing, in particular to an aluminum-plated film cutting device. Background Art

[0002] Aluminum-coated film is a composite flexible packaging material that is formed by coating a very thin layer of metal aluminum on the surface of a plastic film using a special process. Aluminum-coated film is a bright metallic film formed by evaporating high-purity aluminum wire into gas at high temperature through a vacuum aluminum-coating process. When the plastic film passes through a vacuum evaporation chamber, gaseous aluminum molecules precipitate onto the surface of the plastic film. During the processing of high-fastness polyester aluminized film, the aluminized film needs to be cut.

[0003] After searching, it was found that the Chinese patent announcement number is CN216464893U, which discloses a cutting device for high-fastness polyester aluminized film. During the cutting process, the fixing component of the cutting device for high-fastness polyester aluminized film can move downward with the mounting seat, and the pressure plate first contacts the surface of the pad. When the cutting knife continues to move downward, the first spring is gradually compressed. Under the action of the first spring, the surface of the aluminized film can be pressed and fixed by the pressure plate to avoid displacement during cutting. During the winding process, the cleaning component of the cutting device for high-fastness polyester aluminized film can convey the aluminized film along the guide roller. At the same time, under the action of the second spring, the bottom surface of the cotton brush is tightly fitted with the surface of the aluminized film, thereby cleaning the surface of the aluminized film and removing dust and impurities attached to the surface of the aluminized film.

[0004] However, the above patent directly presses the aluminized film through a pressing plate, and the aluminized film between the two pressing plates may be relatively loose, which affects the cutting efficiency. Utility Model Content

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, an aluminum-coated film cutting device includes a base plate 1, and two sets of guide mechanisms are symmetrically arranged on the top of the base plate 1. The guide mechanism includes two vertical plates 201 bolted to the top of the base plate 1, and the two vertical plates 201 are arranged front and back. Two driving rollers 202 are rotatably connected between the two vertical plates 201. The ends of the two driving rollers 202 extend out of the vertical plates 201 and are fixedly connected with gears 203. The two gears 203 are meshed with each other. A rotating motor 204 is bolted to the rear side of the rear vertical plate 201. The output end of the rotating motor 204 is connected to one of the driving rollers 202 through a coupling. The rotating motor 204 is started, and the rotating motor 204 drives one of the driving rollers 202 to rotate, and the other driving roller 202 is driven to rotate through the meshing transmission between the two gears 203, and the aluminum-coated film is guided by the driving roller 202.

[0026] A cutting mechanism is arranged between the two sets of guiding mechanisms, and the cutting mechanism also includes a mounting frame 301 bolted to the top of the base plate 1, the mounting frame 301 is an inverted U-shape, a hydraulic cylinder 302 is fixedly connected to the mounting frame 301, a cross plate 303 is fixedly connected to the bottom of the hydraulic cylinder 302, a cutter 304 is fixedly connected to the bottom of the cross plate 303, a pad 305 is fixedly connected to the top of the base plate 1, a cutting groove is provided on the top of the pad 305, and the cutting groove is located directly below the cutter 304. The hydraulic cylinder 302 is controlled to make the cross plate 303 drive the cutter 304 to move downward, so as to cut the aluminum-plated film.

The initial height of the pressing plate 403 is lower than the height of the cutter 304, so that when moving downward, the pressing plate 403 will first press against the aluminum-plated film, and the top of the vertical rod 402 extends out of the support frame 401 and is fixedly connected to the limiting block 404. The size of the limiting block 404 is larger than the size of the sliding groove, which is convenient for limiting.

[0028] An elastic reset component is provided in the slide groove, and the elastic reset component is used for driving the vertical rod 402 to move toward the direction close to the horizontal plate 303, so as to reset. The elastic reset component includes a top plate 405 slidably connected to the slide groove opened by the support frame 401, and there is no connection between the top plate 405 and the vertical rod 402. The top plate 405 is located on the side of the vertical rod 402 away from the horizontal plate 303. A first spring 406 is connected between the top plate 405 and the side wall of the slide groove. When the vertical rod 402 moves to a certain position, it will contact the top plate 405, driving the top plate 405 to move, and the first spring 406 is compressed. When the vertical rod 402 loses the drive of the power component, the top plate 405 resets under the elastic force of the first spring 406, and the top plate 405 drives the vertical rod 402 to move and reset.

[0029] The pressing mechanism also includes a power assembly, which is used to drive the vertical rod 402 to drive the pressing plate 403 to move in a direction away from the cutter 304, so as to flatten the aluminum-plated film.

[0030] Working principle: When in use, start the rotating motor 204, which drives one of the driving rollers 202 to rotate, and drives the other driving roller 202 to rotate through the meshing transmission between the two gears 203, and guides the aluminized film through the driving roller 202. When the aluminized film needs to be cut, the hydraulic cylinder 302 is controlled to make the cross plate 303 drive the cutter 304 and the pressing mechanism to move downward synchronously, and the pressing plate 403 first contacts the aluminized film, and the cross plate 303 continues to move downward. At this time, the cross plate 303 drives the support frame 401 and the mounting plate 503 to slide downward along the vertical rod 402, and the second spring 505 is compressed. At the same time, the cross plate 303 will also drive the first wedge block 501 fixed on the side wall to move downward, and the downward movement of the first wedge block 501 will drive the second wedge block 504 to move away from the cross plate. The plate 303 moves in the direction of the second wedge block 504, and the second wedge block 504 drives the mounting plate 503 and the connecting rod 502 to move in the direction away from the horizontal plate 303. The mounting plate 503 drives the vertical rod 402 to drive the pressure plate 403 to move in the direction away from the horizontal plate 303, thereby flattening the aluminum-plated film for easy cutting. When the vertical rod 402 contacts the top plate 405, it drives the top plate 405 to move, and the first spring 406 is compressed. After the cutting is completed, the hydraulic cylinder 302 drives the horizontal plate 303 to move upward, and the second wedge block 504 loses the squeezing of the first wedge block 501. The top plate 405 is reset under the action of the elastic force of the first spring 406, and the top plate 405 drives the vertical rod 402 to reset. When the support frame 401 abuts against the limit block 404, the support frame 401 drives the vertical rod 402 and the pressure plate 403 to move upward through the limit block 404, and the cutting is completed.
