Abstract
The utility model relates to a laborsaving hob device of a paper cutter. A plurality of circular hob blades are arranged on two parallel rotating shafts according to scheduled intervals. The diameter of each hob blade is slightly greater than the central distance of two rotating shafts, and the cutting edges of two groups of hob blades are caused to intersect mutually. The hob blade width of each hob is smaller than the spacing of two coaxial neighboring hob blades. An intersecting section is formed by that only one cutting edge flank of each hob blade contacts with the cutting edge flank of the corresponding hob blade in tangent mode. At least one spring with an elasticity and pressure adjusting device is sheathed on one end of one rotating shaft, the hob blades on the rotating shaft and the corresponding hob blades on the opposite rotating shaft are pressed to mutually press close to each other, and then paper can be cut into thin strips.
Description
The utility model relates to a kind of hobboing cutter device of shredder, is specifically related to the hobboing cutter device of office with the improvement of shredder.
The hobboing cutter device of shredder is the most important member of shredder, good hobboing cutter design rolling cut shredded paper not only more laborsaving, save the dynamic horsepower of shredder, and can improve and once eat paper thickness and number.Commonly use shredder tend to cause because of the hobboing cutter apparatus structure is not good eat that the paper amount is little, shredded paper speed slow in addition easily holding paper cause shortcomings such as fault.
At the shortcoming of commonly using the shredded paper hobboing cutter, recently also there are many patent applications to check and approve bulletin, as No. 81108051 (announcing No. 206164) and No. 81215388 (announcing No. 203773), only the hobboing cutter device of this two patent all as shown in Figure 1, that is commonly use the common structure of hobboing cutter, in two rotating shafts 11, equally spaced be provided with A hobboing cutter and B hobboing cutter on 12, the two sides of its each roll blade engage with the side of corresponding roll blade respectively, that is corresponding roll blade A1 is cut in the two sides of roll blade B1, the side of A2, utilize its meet position C1, C2 cuts off the paper by therebetween, so paper will be filled in this clip slot 13 after cutting into slice.This kind commonly used the hobboing cutter device and had following shortcoming:
1. fill in after paper shreds in the space of this clip slot 13, it must be transferred to, therefore must in this clip slot 13, be provided with a plectrum in addition in case paper slip is wound between the roll blade.
2. the two sides because of each roll blade contact with the side of corresponding two roll blades tangently, and its hobboing cutter precision prescribed is higher, and manufacturing cost is higher.
3. the frictional resistance of each roll blade of commonly using hobboing cutter is bigger, and the cutting shredded paper is effort, influences it and eats paper number and shredded paper speed.
The utility model main purpose is to provide a kind of laborsaving hobboing cutter device of shredder, and the paper slip behind its shredded paper is easy to nature and falls, and is difficult for taking place paper jam phenomenon.
An of the present utility model purpose is to provide a kind of laborsaving hobboing cutter device of shredder, and the frictional resistance between its shredded paper roll blade is little, and shredded paper is more laborsaving, can improve tatter amount and shredded paper speed.
Another purpose of the present utility model is to provide a kind of laborsaving hobboing cutter device of shredder, and the meet pressure between its each shredded paper roll blade can be controlled, and guarantees the shredded paper stable operation.
In order to reach above-mentioned purpose, the laborsaving hobboing cutter device of shredder of the present utility model respectively is provided with a plurality of circular roll blades by predetermined space on two parallel shafts, the slightly larger in diameter of each roll blade makes the mutual meet in blade position of two groups of roll blades in the centre-to-centre spacing of two rotating shafts; The width of the roll blade of each hobboing cutter is less than the spacing between coaxial adjacent two roll blades, and each roll blade only has a blade sides and the blade sides of corresponding roll blade to contact to form a meet position tangently; At least one spring housing that has an elastic force pressure adjusting device at a rotating shaft one end to urge corresponding roll blade on roll blade and the countershaft mutually on it with the mutual pressing of certain elastic force pressure, cutting into thin paper slip by the paper between two hobboing cutter groups.
About detailed construction of the present utility model, function and characteristics, can by following to embodiment in conjunction with the accompanying drawings detailed description and be able to abundant understanding.In the accompanying drawings:
Fig. 1 is a kind of hobboing cutter schematic representation of apparatus of commonly using shredder;
Fig. 2 is the schematic top plan view of laborsaving hobboing cutter device of the shredder of an embodiment of the present utility model;
Fig. 3 is the perspective view that the hobboing cutter device cutting paper of shredder shown in Figure 2 is shown.
As Fig. 2, shown in 3, the laborsaving hobboing cutter device of this shredder ties up to a pedestal 21 both sides and is provided with two bearing blocks 22, this diaxon bearing 22 is in order to support two parallel shafts 23,24, this two rotating shaft 23,24 driven by motor and rotation synchronously, wherein equally spaced be provided with multi-disc roll blade N1 in this rotating shaft 23, N2, N3 ... also equally spaced be provided with multi-disc roll blade M1 in another rotating shaft 24 with the interval that equates with above-mentioned interval, M2, M3 ... these roll blades N, the slightly larger in diameter of M is in this two rotating shaft 23, therefore interval D between 24 has a meet position P1 between two roll blade N1 and the M1.The width t1 of roll blade is less than the spacing t2 between two roll blades, therefore each roll blade N1 only engages with the blade position of a corresponding roll blade M1, and these rotating shaft 24 1 ends are arranged with a spring 25 in addition, side is pressured left in order to force the roll blade M that is contained on this, make its each roll blade M1, M2, M3 ... respectively with rotating shaft 23 on a corresponding roll blade N1, N2, N3 ... the blade position be bonded with each other, thereby make meet position P1, P2, P3 ... the roll blade of two relative hobboing cutters keep suitable pressure to be in contact with one another, that is form the set of blades of many group cutting paper.Spring 25 with the device that can adjust its elastic force pressure when roll blade joint situation changes, to adjust spring 25 to keep certain elastic force pressure.For keeping drawing clear, the elastic force pressure adjusting device of this conventional structure is not shown on figure.In addition, the periphery of each hobboing cutter has little sawtooth or annular knurl, opens by the meet position in order to the band paper injection.
As shown in Figure 3, when paper 31 is inserted from the top between two groups of hobboing cutter N, M, paper will be by drawing downwards by between two groups of hobboing cutters, its meet position P1, P2, P3 ... to automatically paper be cut open, that is hobboing cutter N1 and M1, N2 and M2, N3 and M3 ... respectively paper is cut into many fine strip shape shredded paper bars 32, its shredded paper mode of operation is with to commonly use shredder identical; But, the laborsaving hobboing cutter device of shredder of the present utility model is easy to control the pressure and the degree of engagement at the meet position between its two groups of hobboing cutters, this hobboing cutter is not only made and is easier to, and the frictional resistance between two groups of hobboing cutters is less, shredded paper is more laborsaving, can improve shredded paper number and speed, so be innovation uniqueness and the design of tool progressive.
The foregoing description and roll blade shown in the drawings are in order to creativeness of the present utility model and effect to be described as example.Other adopt the improvement of design of the present utility model and modification all should belong to scope of the present utility model.
