Abstract
The utility model discloses a roller and crushing assemblies applied for a machine type data destroying machine, combined with an axle, a plurality of saw bits nested in the axle, axle sleeves and plastic bits. The saw bits are nested in the axle, the axle sleeves are arranged between the saw bit and the saw bit. When the axle is rotated, the saw bits are rotated in company with the axle. Each of the axle sleeves between the saw bit and saw bit is yet jacketed with the plastic bit; the thickness of the plastic bit is slightly less than the thickness of each of the axle sleeves between the saw bit and the saw bit, a gap is left between the plastic bit and the adjacent saw bits, and the purpose is that the plastic bits can not be rotated in company with the saw bits coming along the rotating axle when the rotating axle drives the saw bits to rotate. When the roller incises storage medium, generant chippings can in time slide down through the sidewalls of the plastic bits between the saw bits; the utility model can keep clear between the saw bits, without any retentate. The crushing assemblies applied for a machine type data destroying machine can be also formed from two side-by-side rollers with the same structure.
Description
Technical field

The specific embodiment
As Fig. 1 ~ shown in Figure 5, the disclosed roll that is applied in the data destroying machine of the utility model is combined by axle 1, several saw blades 2, several axle sleeves 3 and several material comb plates 4.
As shown in Figure 5, saw blade 2 and axle sleeve 3 compartment of terrains are enclosed within on the axle 1, and after saw blade 2 closely combined with axle sleeve 3, the saw blade at two ends can be fixed on the axle 1 by nut 5 or pin.When axle 1 rotated, saw blade 2, axle sleeve 3 rotated along with the rotation of axle 1, and cutting stores the storage medium of various information, and storage medium is cut into fragment, reached the purpose of destroying data.
When being with the roll cutting storage medium of several saw blades 2, it is found that the storage medium after being cut very easily is trapped between saw blade and the saw blade.Particularly when destroying CD, because CD is after being cut by saw blade, pulverized particles very easily is trapped between the saw blade, if untimely removing is trapped in these fragments between the saw blade, will increase the cutting resistance, thereby reduce the destruction dynamics of data destroying machine, influence the operate as normal of data destroying machine storage medium.
For the storage medium fragment after preventing to cut is trapped between saw blade and the saw blade, weaken the cutting force of saw blade to storage medium, as Fig. 1, Fig. 6, shown in Figure 7, the utility model is with a material comb plate 4 again on the axle sleeve between saw blade and the saw blade 3.As shown in Figure 4, an end of this material comb plate 4 has a hole 41, and this hole 41 is used for material comb plate 4 is enclosed within axle sleeve 3, and the internal diameter in its hole is slightly larger than the external diameter of axle sleeve 3, and its external diameter is less than the external diameter of saw blade 2; And the thickness of material comb plate 4 is slightly less than the thickness of axle sleeve 3; Its objective is: make after material comb plate 4 is enclosed within on the axle sleeve 3, between material comb plate 4 and the axle sleeve 3 is not tight the connection, and and the saw blade 2 on left and right both sides between also leave the space, when rotating shaft 1 drives saw blade 2, axle sleeve 3 rotations, material comb plate 4 does not rotate with saw blade 2, axle sleeve 3 and rotating shaft 1, thereby the storage medium fragment that is scattered between the saw blade is got off along the sidewall landing of material comb plate 4.
In order to prevent that material comb plate 4 from swinging, as shown in Figure 4, also have a hole 42 at the other end of material comb plate 4, in hole 42, be installed with a fixed bar 6, all material comb plates 4 all are fixed on this fixed bar 6.
When saw blade 2 rotations on the axle 1 drive axle, cutting storage medium, because material comb plate 4 is not along with axle 1 rotates, fragment between the saw blade just can get off along the sidewall landing of material comb plate 4, keep the cleaning between saw blade and the saw blade, the fragment after preventing to cut to be trapped between the saw blade, weaken the cutting force of saw blade.
As shown in Figure 8, utilize two identical rolls of said structure to be arranged side by side and to be combined into a shredder assemblies 7 that is applied in the data destroying machine.This shredder assemblies 7 is to utilize two rolls that are arranged side by side by to rolling, push, cut the storage medium of landing between two rolls, is cut to fragment.Fragment after the cutting gets off by the material comb plate landing that is arranged on each roll.
Shown in Fig. 8,9, two rolls are arranged side by side, and the centre distance between the roll is slightly less than two roll maximum radius sums, make the overlapping slightly setting of saw blade nearest on two rolls; And, the interlaced interlock of saw blade on two rolls.Above-mentioned shredder assemblies 7 can be applied in the data destroying machine as shown in figure 10.
Because the disclosed shredder assemblies that is applied to the roll in the data destroying machine and constitutes of the utility model, be provided with material comb plate between saw blade and the saw blade, so, when roll cutting storage medium, the fragment that produces can in time get off by the sidewall landing of the material comb plate between saw blade and the saw blade, can not be trapped between saw blade and the saw blade, thus the cleaning between the maintenance saw blade, no retentate; Make shredder assemblies can carry out thoroughly storage medium, cut completely.
The above only is preferred embodiment of the present utility model, and protection domain of the present utility model is not limited thereto.Anyly all belong within the utility model protection domain based on the equivalent transformation on the technical solutions of the utility model.
