[0002] In order to protect new products from external dust, they are usually wrapped with a protective film on the outside, which needs to be torn off after the product is purchased. The existing film tearing method usually uses a cutting knife to cut the outer film of the equipment first, and then rewinds it manually. This film tearing method requires a lot of labor and has high labor intensity. Therefore, we have designed a device that can cut the product film on the production line, and can achieve fixed-point cutting, and cooperate with the winding equipment to achieve online winding.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0024] like Figure 1-Figure 5 As shown, a sealing film cutting device includes a support frame 1, a column 2, a first movable bracket 10 and a cutting mechanism 4, the column 2 is connected to the second movable bracket 7 on the support frame 1 through a third connecting support 11, the upper part of the column 2 is provided with a first movable bracket 10 that can be driven up and down, and the first movable bracket 10 is provided with a cutting mechanism 4; the cutting mechanism 4 includes a first connecting support 401, a first pneumatic cylinder 404, a second pneumatic cylinder 406, a driving support 405, a connecting plate 407 and an ultrasonic cutting knife 4 09, the first connecting support 401 is connected to the first sliding bar 14 and the first screw rod 15 on the first movable bracket 10 through the first sliding groove 402 and the first screw hole 403 on one side respectively, and a first pneumatic cylinder 404 is arranged on the upper part of the first connecting support 401, and a second pneumatic cylinder 406 is arranged on the driving support 405 of the first pneumatic cylinder 404, and a first connecting plate 407 and an ultrasonic generator 408 are arranged on the output shaft of the second pneumatic cylinder 406, and an ultrasonic cutting knife 409 is arranged on the ultrasonic generator 408.

[0025] It should be noted that after the production of materials or equipment is completed, in order to avoid dust adhesion and contamination during transportation, they are generally wrapped with a layer of film on the outside, and the purchased products need to have the film torn off before use. In the past, manual methods were generally used, but the materials are of different heights. When encountering higher materials, they must be cut off first and then the film is torn off. Tearing off the film is not easy, so we have designed an automatic film cutting device, in which the cutting mechanism 4 can be raised and lowered under the drive of the first movable bracket 10, thereby cutting off the wrapped film and completing the winding in cooperation with the winding device.

[0026] It needs to be further explained that in order to avoid interference between equipment during transportation, there is a distance between the transport bracket and the cutting equipment at one end. In order to facilitate cutting, the ultrasonic cutting knife 409 needs to be pushed forward to contact the film. Therefore, a first pneumatic cylinder 404 is provided on our first connecting support 401, and the output shaft of the first pneumatic cylinder 404 is connected to the driving support 405, so that the entire second pneumatic cylinder 406 can be pushed forward together with the ultrasonic cutting knife 409 to achieve a first-level push, and the second pneumatic cylinder 406 can push the first connecting plate 407 to achieve a second-level push, thereby completing the two pushes of the ultrasonic cutting knife 409, so that the ultrasonic cutting knife 409 can contact the film to complete the cutting.

[0027] like Figure 5 As shown, a first slide bar 14 and a first screw rod 15 are disposed inside the first movable bracket 10 , and one end of the first screw rod 15 is connected to the first driving motor 9 via a coupling.

[0028] It should be noted that the first movable bracket 10 is used for the vertical movement of the entire cutting mechanism 4 on the column 2, and cooperates with the ultrasonic cutting knife 409 to cut the film, while the second movable bracket 7 is used for the horizontal movement of the entire column 2 together with the cutting mechanism 4 and the adsorption mechanism 3, so as to facilitate the adjustment of various positions.

[0029] like Figure 2 and Figure 6 As shown, it also includes an adsorption mechanism 3, which includes a second connecting support 301, a third pneumatic cylinder 305, a second connecting plate 302 and a suction cup 304. The second connecting support 301 is arranged on the column 2, and the third pneumatic cylinder 305 is arranged at one end of the second connecting support 301, and the second connecting plate 302 is arranged on the output shaft of the third pneumatic cylinder 305; a plurality of suction pipes 303 are arranged on the second connecting plate 302, and a suction cup 304 is arranged on the suction pipe 303.

[0030] It should be noted that when the ultrasonic cutting knife 409 cuts, after cutting the entire wrapped film, one end of the cut will fall to the ground, affecting the subsequent winding. We have designed an adsorption mechanism 3, which can adsorb the film at the cutting point before cutting. On the one hand, it plays a role in stabilizing the cutting point, and on the other hand, it can be combined with the winding equipment to wind up the cut film.

[0031] like Figure 1 and Figure 7 As shown, the third connecting support 11 is connected to the second slide bar and the second screw rod 13 on the second movable bracket 7 through the second slide groove and the second screw hole at the bottom respectively, and one end of the second screw rod 13 is connected to the second driving motor 12 through a coupling; a plurality of supporting legs 8 are arranged at the bottom of the support frame 1, and reinforcing ribs are arranged at the connection between the supporting legs 8 and the support frame 1.

[0032] It should be noted that the third connecting support 11 can be driven by the second driving motor 12 to realize the driving of the entire third connecting support 11 and move left and right, thereby driving the entire upper column 2 to facilitate the adjustment of the working position.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
