Abstract
The utility model relates to a desk paper cutting machine use for cutting document paper, which is composed of an upper cover, a middle cover, a box body and a machine body, wherein, the machine body comprises a wallboard electromotor, two groups of longitudinal knives and spiral transverse knives, and the longitudinal knives and the spiral transverse knives are arranged in a triangle mode. Waste document paper can be cut into strip shape by the two groups of longitudinal knives, and can be cut into granule shape by the spiral transverse knives. The utility model has the advantages of good confidentiality, small size, high relative efficiency and strong practicability.
Description
The utility model relates to the special equipment of doing the paper for copying document fragmentation, promptly a kind of desk-top shredder.
At present, existing strip shredder, it is made up of two groups of rip cutting power, the civilian paper of discarding can only be cut into the strip that does not wait, and therefore, confidentiality is not strong, the requirement of incompatibility office automation.In addition, strip is bulk, volume is big, need often clear up, when taking a lot of work.
It is granular desk-top shredder that the utility model provides a kind of civilian paper of fragmentation.
The utility model realizes that the technical conceive scheme of above-mentioned functions is as follows:
Entire mechanism includes casing, loam cake, and middle cover, wallboard and fuselage, fuselage includes motor, two groups of longitudinal knives, spiral revolving knife and driving gear set.Fuselage is installed on two wallboards, and two wallboards are fixed in the middle cover, and middle cover is mounted on the casing, and loam cake connects middle cover, and its technical characterstic is the below that the spiral revolving knife is assemblied in two groups of vertical cuttves, and the position is triangularly arranged.The gear wheel of cluster gear is with the engagement of motor output gear axle, and pinion is with spiral revolving knife input gears engaged; Spiral revolving knife output gear is with another cluster gear gear wheel engagement, and pinion is a longitudinal knife input gear, and it is again with another group longitudinal knife input gears engaged.
After the good effect that the utility model produces is that the civilian paper of discarding is cut into strip through two groups of longitudinal knives, become graininess through spiral revolving knife rolling cut again, the civilian paper after the fragmentation is not easy splicing, and security performance is good, and some departments or unit are had more practicality.Granular volume is little, reduces the working time of cleaning shredded paper relatively, improves the work efficiency rate of doing.
Below, in conjunction with the accompanying drawings and embodiments, content of the present utility model is described in detail.
Fig. 1 is the utility model topology view.
Fig. 2 is the utility model left side cutaway view.
Structure of the present utility model is by shown in Figure 1, left and right two wallboards 10 are fixed by two long support bolt 3 support and connection, motor 12 is fixedly attached on left wallboard 10, two groups of longitudinal knives 5 and 6 and spiral revolving knife 4 be movably connected on the left and right wallboard 10 by the bearing axle sleeve, spiral revolving knife 4 device is below two groups of longitudinal knives 5 and 6, and their threes' garden heart arrangement position is del.There is pair of projections 14 on two wallboards, 10 upper and lower both sides, a pair of groove interference fit connection that following pair of projections 14 and lower cover 13 are corresponding, and lower cover 13 is mounted on the top of casing 16, and correspondence position offers the paper scrap hole below spiral revolving knife 4.Loam cake 11 and lower cover 13 are connected by screw, and loam cake 11 offers the waste paper ingate at the correspondence position of two groups of rip cutting edges of a knife 5 and 6 incision, is provided with guiding guard 15 in the waste paper importation place and the exit of the two groups of rip cuttings 5 and 6 edges of a knife.Motor 12 output shaft teeth and the engagement of cluster gear 2 gear wheels, cluster gear 2 pinions and 1 engagement of spiral revolving knife 4 input gears drive spiral revolving knife 4 spirals.2600 rev/mins in the utility model motor, through cluster gear 2 two stage speed changes, spiral revolving knife 4 rotating speeds are about 313 rev/mins.Spiral revolving knife 4 output gears 7 mesh with cluster gear 9 gear wheels, 8 engagements of same group of longitudinal knife of the pinion of cluster gear 95 input gears, it is again to organize longitudinal knife 6 input gears separately, driving two groups of longitudinal knives 5 and 6 rotates synchronously, after cluster gear 9 one-level speed changes, two groups of longitudinal knives 5 of the present utility model and 6 rotating speeds are about 51 rev/mins.Discarded civilian paper enters from the ingate, and the net road through two guiding guards 15 constitute enters two groups of longitudinal knives 5 and 6 and is cut into strip, passes through the net road again, directly delivers to spiral shell commentaries on classics revolving knife 4 rolling cuts and becomes graininess, falls into casing 16 from the paper scrap hole.
