Abstract
The invention provides a multistage paper shredding cutter for a paper shredder. The multistage paper shredding cutter for the paper shredder comprises a cutter body, a mounting hole located in the center of the cutter body, a cutting edge located on the circumferential surface of the cutter body, and a blade protruding outwards from the circumferential surface of the cutter body. A concave ring is arranged in a partial position of the outer surface of one side of the cutter body, and a convex ring is correspondingly arranged on the outer surface of the other side of the cutter body. The concave ring and the convex ring are each provided with through holes distributed annularly and uniformly. The multistage paper shredding cutter for the paper shredder is accurate in size and small in loss.
Description
Technical field
The present invention relates to office electric equipment field, specifically the multi-stage paper shredding cutter on a kind of shredder.
Background technology
Owing to shredded paper effect is played conclusive impact by the assembly precision of shredder, the gauge of blade for shredding paper is then the main cause of the assembly precision affecting shredder, therefore, in the course of processing of blade for shredding paper, the gauge of blade for shredding paper is required very strict.The making of existing blade for shredding paper, it is necessary to the belt steel material after finish rolling first strikes out the blade for shredding paper with plane blade, be then assembled together composition paper shredding blade group again by two described blade for shredding paper.But, the strip steel of finish rolling generally there are the thickness deviation of 0.03-0.05mm, owing to a cutter is commonly equipped with the blade for shredding paper of about 60, so, the cumulative thickness tolerance of cutter has just reached 1.8-3mm, thus causing the assembly precision of cutter for paper grinder poor, and then affects shredded paper effect；Additionally, due to existing blade for shredding paper is planar structure, thus the contact area of the blade for shredding paper group causing being positioned on two relative movement cutter shafts is relatively big, and then make the frictional force between two blade for shredding paper big and energy consumption is big.
Send out summary of the invention
(1) to solve the technical problem that
The technical problem to be solved in the present invention is to make the multi-stage paper shredding cutter size on shredder more accurate.
(2) technical scheme
For solving the problems referred to above, a kind of multi-stage paper shredding cutter on the shredder of the present invention, including blade, it is positioned at the installing hole at described blade center, is positioned at the edge of a knife of described blade periphery and from the outwardly blade of described blade periphery, the portion of one side external surface of described blade is provided with scrobicular ring, opposite side outer surface is correspondingly provided with bulge loop, and described scrobicular ring and bulge loop are provided with the through hole that annular is uniform mutually.
Described scrobicular ring is located at the position between the edge of a knife and the installing hole of a side external surface of described blade.
Described bulge loop is located at the position between the edge of a knife and the installing hole of the opposite side outer surface of described blade, and described bulge loop and described scrobicular ring are correspondingly arranged.
(3) beneficial effect
Compared with prior art, one side external surface of the blade of blade for shredding paper of the present invention is provided with bulge loop, the design of described bulge loop compensate for the gauge deviation of the blade for shredding paper caused because of the finish rolling tolerance of belt steel material, it is ensured that the gauge of blade for shredding paper is accurate, so that the assembly precision of shredder is high, shredded paper is effective；In addition, the opposite side outer surface of the blade of described blade for shredding paper is provided with scrobicular ring, the design of described scrobicular ring makes the contact area of the blade for shredding paper being located on the cutter shaft of two relative movements diminish, and therefore reduces the frictional force between blade for shredding paper, so that shredded paper energy consumption is little.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
As depicted in figs. 1 and 2, a kind of multi-stage paper shredding cutter on the shredder of the present invention, including blade 10, it is positioned at the installing hole 11 at described blade center, is positioned at the edge of a knife 12 of described blade 10 periphery and from the outwardly blade 13 of described blade periphery, the portion of one side external surface of described blade 10 is provided with scrobicular ring 14, opposite side outer surface is correspondingly provided with bulge loop 15, and described scrobicular ring 14 and bulge loop 15 are provided with the through hole 16 that annular is uniform mutually.
Described scrobicular ring 14 is located at the position between the edge of a knife 12 and the installing hole 11 of a side external surface of described blade 10.
Described bulge loop 15 is located at the position between the edge of a knife 12 and the installing hole 11 of the opposite side outer surface of described blade 10, and described bulge loop 15 is correspondingly arranged with described scrobicular ring 14.
Compared with prior art, one side external surface of the blade of blade for shredding paper of the present invention is provided with bulge loop, the design of described bulge loop compensate for the gauge deviation of the blade for shredding paper caused because of the finish rolling tolerance of belt steel material, it is ensured that the gauge of blade for shredding paper is accurate, so that the assembly precision of shredder is high, shredded paper is effective；In addition, the opposite side outer surface of the blade of described blade for shredding paper is provided with scrobicular ring, the design of described scrobicular ring makes the contact area of the blade for shredding paper being located on the cutter shaft of two relative movements diminish, and therefore reduces the frictional force between blade for shredding paper, so that shredded paper energy consumption is little.It is possible to prevent blade 10 to rotate by arranging through hole.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
