The purpose of the utility model can be realized by the following technical scheme: a cutter distribution structure for slitting extremely narrow materials comprises an upper cutter shaft and a lower cutter shaft on an aluminum strip slitting machine, wherein the upper cutter shaft and the lower cutter shaft are arranged in parallel up and down, the upper cutter shaft and the lower cutter shaft are respectively provided with a disc cutter, a female sleeve and a male sleeve, a plurality of disc cutters on the upper cutter shaft and the lower cutter shaft are arranged at intervals, a female sleeve or a male sleeve is arranged between every two adjacent disc cutters, the female sleeves and the male sleeves on the upper cutter shaft and the lower cutter shaft are arranged at intervals one by one, the female sleeves on the upper cutter shaft correspond to the male sleeves on the lower cutter shaft in position, and the male sleeves on the upper cutter shaft correspond to the female sleeves on the lower cutter shaft in position; the female sleeve comprises a first spacing ring arranged on the cutter shaft and a rubber ring sleeved on the first spacing ring, and the male sleeve comprises a second spacing ring arranged on the cutter shaft and a steel sleeve sleeved on the second spacing ring; the disc cutters at corresponding positions on the upper cutter shaft and the lower cutter shaft are provided with horizontal gaps in the horizontal direction.

Furthermore, both ends of the upper cutter shaft and the lower cutter shaft are fixed through a bearing and a bearing box.

Furthermore, the outer diameter of the rubber ring is 0.6-1 mm smaller than the diameter of the disc cutter.

Further, the outer diameter of the steel sleeve is smaller than the diameter of the cutting disc by more than 35 mm.

Further, the horizontal gap is 20% -30% of the thickness of the material.

Compared with the prior art, the beneficial effects of the utility model are that: the rubber ring of the female sleeve can support the belt material and eject the belt material in time; the male sleeve adopts a steel sleeve to replace an original rubber ring, and has the functions of eliminating the ejection effect of the original rubber ring of the male sleeve on the strip, avoiding the strip from being clamped between the circular cutters on the upper cutter shaft and the lower cutter shaft, and reducing the left-right swinging distortion of the strip in the slitting process; according to the thickness of the strip, a proper horizontal gap is arranged between the circular cutters at the corresponding positions on the upper cutter shaft and the lower cutter shaft, so that the situation that the strip is deflected left and right due to the fact that the strip is clamped between the circular cutters at the two sides of the female sleeve is avoided.

Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings to make it clear to those skilled in the art how to practice the invention. While the invention has been described in connection with its preferred embodiments, these embodiments are intended to be illustrative, and not to limit the scope of the invention.

Referring to fig. 1 to 3, a cutter allocation structure for slitting extremely narrow materials comprises an upper cutter shaft 1 and a lower cutter shaft 2 on an aluminum strip slitting machine, wherein the upper cutter shaft 1 and the lower cutter shaft 2 are arranged in parallel up and down, and two ends of the upper cutter shaft 1 and two ends of the lower cutter shaft 2 are fixed at precise positions through bearings and bearing boxes, so that a vertical gap between the upper cutter shaft 1 and the lower cutter shaft 2 can be adjusted according to the thicknesses of different materials.

Go up and all install circle disc cutter 3, female cover a, public cover b on arbor 1 and the lower arbor 2, go up a plurality of circle disc cutters 3 interval arrangement on arbor 1 and the lower arbor 2 to be equipped with a female cover a or a public cover b between two adjacent circle disc cutters 3, go up arbor 1 and the female cover a and the public cover b on the lower arbor 2 and all be the interval setting one by one, go up the female cover a on arbor 1 and the public cover b position on the lower arbor 2 corresponding, go up the public cover b on arbor 1 and the female cover a position on the lower arbor 2 corresponding.

The female sleeve a comprises a first spacing ring 4 arranged on the cutter shaft and a rubber ring 5 sleeved on the first spacing ring 4, the outer diameter of the rubber ring 5 is 0.6-1 mm smaller than the diameter of the circular disc cutter 3, and the rubber ring 5 can not only support a strip, but also eject the strip in time; the male sleeve b comprises a second spacing ring 6 arranged on the cutter shaft and a steel sleeve 7 sleeved on the second spacing ring 6, the outer diameter of the steel sleeve 7 is smaller than the diameter of the circular disc cutter 3 by more than 35mm, the steel sleeve 7 is adopted to replace the rubber ring 5 of the original male sleeve b, the ejection effect of the rubber ring 5 of the original male sleeve b on a strip can be eliminated, the strip is not clamped between the circular disc cutters 3 on the upper cutter shaft 1 and the lower cutter shaft 2, and the left-right distortion of the strip in the cutting process is reduced.

Referring to fig. 3 and 4, the circular cutters 3 at corresponding positions on the upper cutter shaft 1 and the lower cutter shaft 2 have a horizontal gap c in the horizontal direction. During installation, the vertical clearance between the upper cutter shaft 1 and the lower cutter shaft 2 is slowly reduced, so that the disc cutters 3 on the upper cutter shaft 1 and the lower cutter shaft 2, which correspond to the same side of the female sleeve a and the male sleeve b, are accurately overlapped according to the set horizontal clearance c, and therefore the aluminum coil materials are stably and neatly cut and conveyed to the other sides of the upper cutter shaft 1 and the lower cutter shaft 2 from one sides of the upper cutter shaft 1 and the lower cutter shaft 2 through the shearing of the disc cutters 3 and the jacking of the female sleeve a and the male sleeve b.

The horizontal clearance c is 20% -30% of the thickness of the material, and the horizontal clearance c ensures that the cut strip can swing in enough space between the circular disc cutters 3 on the two sides of the female sleeve a, so that the strip cannot be clamped between the circular disc cutters 3 on the two sides of the female sleeve a due to too small clearance, the strip is out of the cutter and is deflected and twisted, the strip is bent after being coiled, and the camber is unqualified.

It should be noted that many variations and modifications of the embodiments of the present invention are possible, which are fully described, and are not limited to the specific examples of the above embodiments. The above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. In conclusion, the scope of the present invention should include those changes or substitutions and modifications which are obvious to those of ordinary skill in the art.
