Detailed Description

While the embodiments of the present invention will be described and illustrated in detail with reference to the accompanying drawings, it is to be understood that the invention is not limited to the specific embodiments disclosed, but is intended to cover various modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims.

As shown in fig. 1-6, the present embodiment discloses a self-cleaning grinding lubrication package for a paper shredder, comprising a grinding envelope 1, a grinding lubrication sheet 2 and a folded edge 3, wherein:

the grinding lubrication sheet 2 is fixed on the grinding envelope 1 and is used for grinding and lubricating the cutter of the paper shredder. As shown in fig. 1 and 2, in the present embodiment, the polishing pad 2 is attached to the right side of the polishing cover 1, and may be attached to the left side, the right side, or the middle in actual operation, as long as the polishing pad 2 can be folded in half and then enter the paper inlet. In addition, in this embodiment, the thicknesses of the packing materials of the grinding lubricant sheet 2 and the grinding seal cover 1 are not limited, and only the characteristic of being thin is required, and the grinding lubricant sheet 2 and the grinding seal cover 1 can be folded into two and then enter the paper inlet for grinding and lubricating without being too thick.

The folded edge 3 is formed by extending at least one short edge of the grinding envelope 1 outwards, or the folded edge 3 is directly fixed (or in a sticking mode) on at least one short edge of the grinding envelope 1 and is used for generating friction force between the folded edge 3 and the upper surface of the paper supporting plate of the paper shredder so as to take away paper scrap on the paper supporting plate or paper shredder cutters from one side or two sides of the paper inlet.

In a preferred embodiment, the folded edge 3 is formed by extending the short edges of the two sides of the grinding sleeve 1 outwards, or the folded edge 3 is directly fixed on the short edges of the two sides of the grinding sleeve 1. The two sides of the grinding envelope 1 are provided with the folded edges 3, so that paper scrap and powder on the paper supporting plates on the two sides of the paper inlet can be more efficiently brought into the paper inlet to be ground.

Preferably, the plane of the folded edge 3 is at an angle of 0-90 degrees to the plane of the grinding sleeve 1, so that the folded edge 3 is in contact with the upper surface of the paper supporting plate, thereby generating corresponding friction force.

Preferably, the folded edge 3 is made of paper or a PP bag (stretchable polypropylene plastic). In actual operation, the material of the folded edge 3 is not limited, and only the requirement on hard characteristics is met, and the folded edge 3 and the upper surface of the paper supporting plate can generate enough friction force due to certain hardness, so that paper scrap on the paper supporting plate is scraped.

Preferably, the width of the folded edge 3 along the long side direction of the grinding sleeve 1 is 5-15 mm. In this embodiment, the width is not limited, and in practical operation, the width is preferably 10 mm.

Preferably, the combined dimensions of the grinding envelope 1 and the flap 3 have a length and width respectively smaller than the length and width of the paper-shredder paper-holding box. In particular, the maximum size of the combination of the abrasive envelope 1 and the folded edge 3 is 210 x 297mm (the size of conventional a4 paper) or 216 x 279mm (the size of LITTERSIZE).

In another embodiment, as shown in fig. 2, the folded edge 3 is composed of a plurality of small folded edges 4, and the small folded edges 4 are arranged at equal intervals or unequal intervals along the short side direction of the grinding envelope 1. Preferably, the distance between any two adjacent small folded edges 4 is not more than 5mm, and is less than the width of conventional paper scraps on the market, so that the small folded edges can be effectively brought into a paper inlet to be cleaned. In addition, the small folded edges 4 may be arranged with equal width or different width along the short side direction of the grinding envelope 1, and preferably with equal width.

Preferably, the small folding edges 4 are triangular, rectangular, trapezoidal or zigzag. In this embodiment, the small folded edge 4 can be in any shape, but the rectangle is the best, the largest contact surface can be formed between the small folded edge and the upper surface of the paper supporting plate, and the cleaning effect is better.

In this embodiment, the grinding envelope 1 may be made of sandpaper, non-woven fabric or sponge. Preferably, the grinding envelope 1 is sandpaper, which is thin and breakable and easily accessible. The front surface and the back surface of the abrasive paper are both uniformly adhered with a plurality of grinding particles, so that the surface of the passivated paper shredder cutter is effectively ground.

In addition, the inside of the grinding lubricant sheet 2 is uniformly coated with solid grease, which is lithium grease without strong fluidity, and the lithium grease does not explode, thereby dirtying the hands of a user or a paper shredder. The solid lubricating grease can be well attached to the surface of a paper shredder cutter due to poor fluidity, has good lubricating effect, is not easy to pollute hands, waste paper and the paper shredder, ensures that the waste paper can be well recycled, and has the characteristics of more thorough grinding and more in-place lubrication.

The specific working process is as follows:

referring to fig. 5 and 6, when the shredder needs to be maintained, oiled and ground, the shredder is put at the lowest part or middle of the stacked paper to be shredded by a self-cleaning grinding lubrication bag, and is fed into the paper inlet of the shredder and is shredded in a paper feeding mode, the folded edge 3 (or a plurality of small folded edges 4) and the upper surface of the paper supporting plate of the shredder generate friction force to take away paper scrap on the paper supporting plate or on the cutter of the shredder from one side or two sides of the paper inlet, meanwhile, in the process of cutting the self-cleaning grinding lubricating bag by the cutter of the paper shredder, because the grinding particles outside the grinding substrate are contacted, so that the passivated, uneven-surface or crimped tool surface is effectively and fully ground, and because of the contact with the lubricating grease which is saturated by the grinding lubrication slip sheet 2, so that the solid lubricating grease with poor fluidity is attached to the surface of the cutter, and the purpose of grinding and lubricating the cutter to prolong the service life of the cutter of the paper shredder is achieved. The maintenance and the oiling work of the paper shredder can be completed without manual lubrication, and the paper shredder is convenient and quick and has low maintenance cost. In addition, the self-cleaning effect of the paper scrap and the paper dust on the paper supporting plate and the paper shredder cutter is realized.

The mode of utilizing above-mentioned automatically cleaning to grind lubricated package in order to reach grinding, lubrication and automatically cleaning effect not only is very convenient to the consumer, and the paper shredder cutter can evenly contact with abrasive grain and lubricating grease moreover, in addition, visual actual conditions improves required grinding, lubrication and automatically cleaning effect through cutting more than one automatically cleaning grinds lubricated package.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
