Technical Field
[0001] The invention relates to the field of grinding lubricating bags, in particular to a self-cleaning grinding lubricating bag for a paper shredder. Background Art
[0002] Existing grinding or oil bags are placed through the paper inlet of an automatic shredder. After being cut open by the blades, the grinding powder or oil is applied to the blade surface to produce a grinding and lubricating effect. Paper scraps and other debris often accumulate in the shredder's paper tray, requiring the shredder to be opened and manually removed with a brush, which is neither safe nor thorough.
[0003] The solution of the present invention is to improve the existing grinding bag in view of the above problems. Summary of the Invention
[0004] In order to overcome the deficiencies in the prior art, the present invention provides a self-cleaning grinding and lubricating bag for a paper shredder, which improves the two folded edges of the original grinding bag and utilizes the phenomenon that the automatic paper shredder cutter pulls the paper box cleaning grinding and lubricating bag (or sheet), thereby achieving multiple goals at one stroke, grinding and lubricating the cutter and cleaning the paper box.
[0005] In order to achieve the above-mentioned purpose of the invention, the technical solutions adopted to solve the technical problems are as follows:
[0006] A self-cleaning grinding lubrication pack for a paper shredder, comprising a grinding sleeve, a grinding lubrication sheet and a folded edge, wherein:
[0007] The grinding lubricating sheet is fixed on the grinding sleeve and is used for grinding and lubricating the shredder cutter;
[0008] The folded edge is formed by extending outward from at least one short side of the grinding cover, or the folded edge is directly fixed to at least one short side of the grinding cover, and is used for generating friction between the folded edge and the upper surface of the shredder support board, thereby removing paper scraps on the support board or the shredder blade from one side or both sides of the paper inlet.
[0009] Preferably, the folded edges are formed by extending outwards from both short sides of the grinding envelope, or the folded edges are directly fixed to both short sides of the grinding envelope.
[0010] Preferably, the angle between the plane where the folded edge is located and the plane where the grinding sleeve is located is between 0 and 90 degrees.
[0011] Preferably, the folded edge is made of paper or PP bag.
[0012] Preferably, the width of the folded edge along the long side direction of the grinding sleeve is 5-15 mm.
[0013] Preferably, the length and width of the combined dimensions of the grinding sleeve and the folded edge are respectively smaller than the length and width of the paper shredder's paper support box.
[0014] Furthermore, the folded edge is composed of a plurality of small folded edges, and the plurality of small folded edges are arranged at equal or unequal intervals along the short side direction of the grinding envelope.
[0015] Preferably, the distance between any two adjacent small folded edges is no more than 5 mm.
[0016] Preferably, the plurality of small folded edges are arranged with equal or unequal widths along the short side direction of the grinding envelope.
[0017] Preferably, the small folded edges are in the shape of a triangle, a rectangle, a trapezoid or a sawtooth.
[0018] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:
[0019] The present invention places a self-cleaning abrasive lubricating pack for a shredder at the bottom or center of a stack of paper to be shredded, feeds it into the shredder's paper inlet, and shreds it in a paper-feeding mode. The folded edge generates friction with the upper surface of the shredder's paper support plate, thereby removing paper scraps from the paper support plate or shredder cutters from one or both sides of the paper inlet. Simultaneously, as the shredder cutters cut the self-cleaning abrasive lubricating pack, contact with abrasive particles outside the grinding base effectively and fully grinds dull, uneven, or curled cutter surfaces. Contact with the grease contained in the abrasive lubricating sheet causes the less fluid solid grease to adhere to the cutter surface, thereby grinding and lubricating the cutter to extend the life of the shredder cutter. This eliminates the need for manual lubrication, allowing for convenient and low-cost maintenance and oiling of the shredder. Furthermore, the self-cleaning effect of paper scraps on the paper support plate and shredder cutters is achieved. The present invention has a simple structure, is easy to use, and can significantly improve grinding, lubricating, and cleaning effects, performing the multiple functions of grinding, lubricating, and cleaning.

[0032] The following will clearly and completely describe and discuss the technical solutions in the embodiments of the present invention in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0033] like Figure 1-6 As shown, this embodiment discloses a self-cleaning grinding lubricating pack for a paper shredder, comprising a grinding cover 1, a grinding lubricating sheet 2 and a folded edge 3, wherein:
[0034] The grinding lubricating sheet 2 is fixed on the grinding sleeve 1 and is used for grinding and lubricating the shredder cutter. Figure 1 and 2 As shown, the grinding lubricating sheet 2 in this embodiment is attached to the right side of the grinding envelope 1. In actual operation, it can be attached to the left, right, or center, as long as the grinding lubricating sheet 2 can be folded in half and inserted into the paper inlet. In addition, in this embodiment, there is no limit on the thickness of the packaging material of the grinding lubricating sheet 2 and the grinding envelope 1. It only needs to be thin and not too thick to allow the grinding lubricating sheet 2 and the grinding envelope 1 to be folded in half and inserted into the paper inlet for grinding lubrication.
[0035] The folded edge 3 is formed by extending outward from at least one short side of the grinding cover 1, or the folded edge 3 is directly fixed (or pasted) on at least one short side of the grinding cover 1, so as to generate friction between the folded edge 3 and the upper surface of the shredder support board, thereby removing paper scraps on the support board or the shredder blade from one side or both sides of the paper inlet.
[0036] In a preferred embodiment, the folded edges 3 are formed by extending outwards from the short sides of the grinding envelope 1, or the folded edges 3 are directly fixed to the short sides of the grinding envelope 1. Providing folded edges 3 on both sides of the grinding envelope 1 can more efficiently bring paper scraps on the supporting boards on both sides of the paper inlet into the paper inlet for crushing.
[0037] Preferably, the angle between the plane where the folded edge 3 is located and the plane where the grinding sleeve 1 is located is between 0 and 90 degrees, so that the folded edge 3 contacts the upper surface of the supporting paper board, thereby generating corresponding friction force.
[0038] Preferably, the folded edge 3 is made of paper or PP bag (stretchable polypropylene plastic). In actual operation, there is no limitation on the material of the folded edge 3, as long as it is hard. A certain hardness can generate sufficient friction between the folded edge 3 and the upper surface of the support paper board, thereby scraping away paper scraps on the support paper board.
[0039] 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, there is no limitation on the width. In actual operation, the width is preferably 10 mm.
[0040] Preferably, the length and width of the combined dimensions of the grinding envelope 1 and the folded edge 3 are respectively smaller than the length and width of the paper shredder tray. Specifically, the maximum size of the combined dimensions of the grinding envelope 1 and the folded edge 3 is 210*297mm (the size of conventional A4 paper) or 216*279mm (the size of a litter size).
[0041] In another embodiment, if Figure 2 As shown, the folded edge 3 is composed of several small folded edges 4, which are arranged at equal or unequal intervals along the short side of the grinding envelope 1. Preferably, the distance between any two adjacent small folded edges 4 is no greater than 5 mm, which is smaller than the width of conventional paper scraps on the market, allowing them to be effectively carried into the paper inlet for cleaning. Furthermore, the several small folded edges 4 can be arranged with equal or unequal widths along the short side of the grinding envelope 1, with equal width being preferred.
[0042] Preferably, the small folds 4 are triangular, rectangular, trapezoidal or zigzag. In this embodiment, the small folds 4 can be in any shape, but a rectangle is the best, which can maximize the contact surface with the upper surface of the supporting paper board and achieve better cleaning effect.
[0043] In this embodiment, the grinding envelope 1 can be made of sandpaper, non-woven fabric, or sponge. Preferably, the grinding envelope 1 is sandpaper, which is thin, breakable, and readily available. Abrasive particles are evenly attached to both sides of the sandpaper, effectively grinding the dulled shredder tool surface.
[0044] Furthermore, the interior of the grinding lubricating sheet 2 is evenly coated with solid grease. This solid grease is a lithium-based grease with low fluidity. This grease does not burst and stain the user's hands or the shredder. Due to its low fluidity, the solid grease adheres well to the shredder blade surface, providing excellent lubrication and preventing contamination of hands, waste paper, or the shredder itself. This allows waste paper to be reused, resulting in more thorough grinding and enhanced lubrication.
[0045] Specific workflow:
[0046] refer to Figure 5 and 6 When the shredder needs maintenance and oiling, the self-cleaning abrasive lubricating pack is placed at the bottom or center of the stack of paper to be shredded, fed into the shredder's paper inlet, and shredded in paper-feed mode. The folded edge 3 (or several small folded edges 4) creates friction with the upper surface of the shredder's paper support, removing paper scraps from the paper support or shredder's blades from one or both sides of the paper inlet. Simultaneously, as the shredder's blades cut through the self-cleaning abrasive lubricating pack, they contact abrasive particles outside the grinding base, effectively and fully grinding blunt, uneven, or curled blade surfaces. Contact with the grease contained in the abrasive lubricating sheet 2 causes the less fluid solid grease to adhere to the blade surface, effectively grinding and lubricating the blades and extending the life of the shredder's blades. This eliminates the need for manual lubrication, allowing for convenient and quick maintenance with low maintenance costs. Furthermore, the self-cleaning effect of paper scraps on the paper support and shredder blades is achieved.
[0047] The method of using the above-mentioned self-cleaning abrasive lubricating pack to achieve the grinding, lubricating and self-cleaning effects is not only very convenient for consumers, but also allows the shredder cutter to be in uniform contact with the abrasive particles and grease. In addition, the desired grinding, lubricating and self-cleaning effects can be improved by cutting more than one self-cleaning abrasive lubricating pack according to actual conditions.
[0048] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
