Description

Technical Field

[0001] The utility model relates to the technical field of firecracker production, in particular to a paper sheet cutting device for firecracker production. Background Art

[0002] Fireworks and firecrackers refer to arts and crafts made from pyrotechnic powder as raw materials. They are entertainment products that burn (explode) through the action of ignition sources and are accompanied by sound, light, color, smoke, fog and other effects. The original purpose of firecrackers was to welcome gods and expel ghosts. Fireworks are works of art that focus on visual effects. Later, they developed into a symbol of bidding farewell to the old and welcoming the new with their strong festive colors. Burning fireworks and firecrackers can create a festive and lively atmosphere. It is a kind of entertainment activity during festivals and can bring joy and good luck to people. The entire production process of fireworks and firecrackers has more than 70 processes, which can basically be summarized as four major processes: paper tube production, gunpowder (nitrate) material production, fuse production, and finished fireworks production. Among them, paper cutting is required during the production of paper tubes.

[0003] For example, the Chinese patent publication number CN212193298U, "A cutting device for paper production", discloses a cutting device for paper production, including a housing, the top of the housing is fixedly connected to a motor, the surface of the motor shaft is fixedly connected to a rotating rod, the bottom end of the rotating rod extends to the inside of the housing, the bottom end of the rotating rod is fixedly connected to a worm, and one side of the worm is meshed with a worm wheel. The utility model can drive the box to move up and down by setting a motor, a rotating rod, a worm wheel, a worm, a rotating disk, a support column, a support plate, a moving plate, a fixed plate and a baffle, and can drive the first cutting blade to move downward by setting a first rod shaft, a fixed block, a first tooth plate, a telescopic push rod and a horizontal plate, and can drive the second cutting blade to work upward by setting a second rod shaft, a support block, a second tooth plate and a vertical plate, so that the cutting device is simple to operate, has high work efficiency, reduces the labor intensity of the staff, and is convenient for people to use.

[0004] However, in actual use, when paper sheets of different widths need to be cut, since the size of the paper raw material is fixed, it is necessary to cut it again after cutting it to a suitable length to cut it to a suitable width. It is not convenient to cut the width of the paper sheet at the same time as cutting the length of the paper sheet, and it is not convenient to cut the paper sheet more efficiently.

A second cutting component 5 is arranged on the right side of the lifting plate 304, and the first cutting component 4 also includes a disc cutter 403. The number of the disc cutters 403 is two. The disc cutter 403 located at the rear is fixedly installed under the slider 402, and the disc cutter 403 located at the front is fixedly installed under the lifting plate 304. An electric telescopic rod 404 is arranged between the two disc cutters 403. The disc cutter 403 includes a cutter seat and a disc blade. The disc blade is rotatably arranged, and the cutter seat is arranged at the top. The front and rear ends of the electric telescopic rod 404 are respectively fixedly connected to the two disc cutters 403.

[0027] In this embodiment, when the width of a paper sheet needs to be cut, the paper sheet is first placed on the base 1, and then the electric telescopic rod 404 pushes the disc cutter 403 located at the rear to make the slider 402 on the disc cutter 403 slide on the slide rail 401, thereby adjusting the distance between the two disc cutters 403. After the appropriate width is adjusted, the first hydraulic push rod 302 pushes the lifting plate 304 down, so that the two disc cutters 403 pierce the paper sheet and fall into the cylindrical groove 2. At this time, as the paper sheet slides to the right, the disc blades on the two disc cutters 403 rotate and continuously cut the paper sheet, thereby achieving the effect of cutting the width of the paper sheet.

[0028] Example 2

[0029] like Figure 1-4As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the second cutting component 5 includes a cutting groove 501, the cutting groove 501 is opened above the base 1, a cutting seat 502 is arranged above the cutting groove 501, two supporting strips are arranged below the cutting seat 502 to leave a gap below the cutting seat 502 for passing paper sheets, the cutting seat 502 is fixedly connected to the right side of the lifting plate 304, a cutter 503 is movably penetrated above the cutting seat 502, the cutter 503 is adapted to the cutting groove 501, a pushing piece 504 is fixedly connected above the cutter 503, a pushing component 6 is arranged above the cutting seat 502, the pushing component 6 includes a second supporting frame 601, the second supporting frame 601 is fixedly connected to the top of the cutting seat 502, and a second hydraulic push rod 6 is fixedly connected to the top of the inner surface of the second supporting frame 601 02, the lower end of the second hydraulic push rod 602 is fixedly connected to the top of the push piece 504, and a spring 603 is elastically connected between the top of the push piece 504 and the top of the inner surface of the second support frame 601.
