Specific embodiment
With reference to Figure of description, the present invention is described in detail.
As shown in Figure 1, Figure 2 and Figure 3, the invention provides a kind of hard disk pulverizer, including frame 10, frame 10 is provided with
Feeding mouth 11, is provided with driving means 30 and reducing mechanism 40 in frame 10, driving means 30 provide for the operation of whole equipment
Power, specifically, the chain drive that driving means 30 include motor 31 and driven operating by motor 31, chain
Drive mechanism includes drive sprocket 33, chain 34 and the driven sprocket 35 being sequentially connected, and the motor shaft of motor 31 stretches out electricity
Support 32 1 segment distance, drive sprocket 33 is arranged on the external part of this motor shaft, and the outer end of drive sprocket 33 is by being arranged on electricity
Shaft-cup 36 on arbor limits its position, prevents drive sprocket 33 from shaking.When motor 31 rotates, drive sprocket 33
Motor shaft with motor 31 rotates, and passes motion to driven sprocket 35 by chain 34 simultaneously.
Reducing mechanism 40 includes the driving shaft 41 being arranged side by side and driven shaft 42, and driven sprocket 35 is arranged on driving shaft 41
Right-hand member.The present invention adopts chain drive, this mode transmission speed accurate stable, and transmission energy meets demand, installation side
Formula compact and reasonable, plays the effect of safe buffering between motor 31 and driving shaft 41, it is to avoid motor 31 and active
The damage of axle 41.
Driving shaft 41, the left end of driven shaft 42 are separately installed with intermeshing driving gear 43 and driven gear 44, main
Moving axis 41 drives synchronous axial system by driven sprocket 35, simultaneously by the engaged transmission of driving gear 43 and driven gear 44 make from
Moving axis 42 rotates, and this connected mode makes driving shaft 41 and driven shaft 42 have different rotating speeds simultaneously.
In conjunction with Fig. 3 and Fig. 4, driving shaft 41 and driven shaft 42 are separately installed with multigroup spaced profile of tooth cutterhead 462,
It is respectively arranged with circle every disk 461, profile of tooth cutterhead 462 is the fluted disc containing 9 cutters tooth, profile of tooth between adjacent profile of tooth cutterhead 462
The inclined acute angle of cutter tooth on cutterhead 462, and profile of tooth cutterhead 462 is by the contrary fluted disc group side by side of two groups of cutter tooth incline directions
Become.
Two on the driving shaft 41 and driven shaft 42 adjacent mutual sandwicheds of profile of tooth cutterhead 462, and correspond respectively to driven
Every disk, the circle of the Arbitrary Relative gap between disk and profile of tooth cutterhead is formed for crushing hard disk circle on axle and driving shaft
Gap.That is, between two adjacent profile of tooth cutterheads that on driving shaft, profile of tooth cutterhead is inserted on driven shaft 42, and and driven shaft
Every disk relatively, gap therebetween forms the gap for crushing hard disk to circle on 42.On driven shaft, profile of tooth cutterhead is same
Between two adjacent profile of tooth cutterheads being inserted on driving shaft and relative every disk with the circle on driving shaft, therebetween
Gap also forms the gap for crushing hard disk.
Because driving shaft 41 is different with the rotating speed of driven shaft 42, therefore in the cutterhead 46 on driving shaft 41 with positioned at driven
The rotating speed of the cutterhead 46 on axle is different, and the interval speed for 5-9 rev/min that selects of usual rotating speed rotates, and is easy to bring hard disk into
Cut off between two profile of tooth cutterheads 462 on adjacent driving shaft 41 and driven shaft 42, generation relatively can also be alleviated
Pressure.It is provided with lock tube 45, for limiting cutterhead 46 at the upper and lower ends face that cutterhead 46 is located on driving shaft 41 and driven shaft 42
Position, reduces vibration at work and noise.
For ensureing the gap consistent (within 0.4 millimeter) between each profile of tooth cutterhead 462, and accomplish to go slick and be cut with
Power, all by the way of fine grinding, lateral surface is concordantly bright and clean.
In addition, the selection principle of material to profile of tooth cutterhead 462 and Technology for Heating Processing is: ensureing cutterhead 46 profile of tooth cutterhead
Also to have enough toughness on the premise of 462 hardness and wearability, with ensure overload when shut down and profile of tooth cutterhead 462 will not break
Split.Need to through strict Technology for Heating Processing it is ensured that the normal operation of machine, and be amenable to pulverize magnetic material and steel shaft core for a long time
Abrasion to profile of tooth cutterhead 462.So profile of tooth cutterhead 462 is made using high duty alloy tool steel, using forging and stamping, quenched, cutting,
The techniques such as vacuum hardening, plain grinding make.With making driving shaft 41 and driven through quenched structural alloy steel through modifier treatment
Axle 42.
Present invention additionally comprises multiple separate comb tablet 50, separate the fragment after comb tablet 50 is used for pulverizing hard disk and clean out in time
Go, multiple comb tablets 50 that separate are divided into two groups, and are separately positioned on driving shaft 41 and the outside of driven shaft 42, separate comb tablet 50 and pass through
The comb tablet axle 51 that many are arranged in frame 10 is fixed in frame 10, separates comb tablet 50 and is folded in driving shaft 41 and driven respectively
Between adjacent two profile of tooth cutterhead on axle 42.Separate comb tablet 50 to be also made up of side by side two panels.
Specifically, two side plates 52 of frame 10 are connected by connecting plate 53, and two side plates 52 have multiple passing through
The axis hole worn, many comb tablet axles 51 are separately mounted in axis hole.
The middle part separating comb tablet 50 has semi arch hole 501, the diameter in semi arch hole 501 and the circular diameter every disk 461
Identical, and abut in circle on the outer circumference surface of disk 461.Fringe after hard disk chopping may be wrapped in circle on disk,
It is actionless for separating comb tablet 50, and with the rotation of driving shaft, driven shaft, the peristome separating the semi arch hole in comb tablet 50 will
It is wrapped in circular hard disk fringe rejecting on disk, fall into the discharging opening of lower section, and then enter debris box.
In conjunction with Fig. 1, present invention additionally comprises overload protective device, overload protective device includes being arranged on the end head of driving shaft 41
Annular magnet 60, the Hall element 61 being arranged on annular magnet 60 outside and the electricity for being switched on or switched off described motor
The relay in source, the magnetic line of force of annular magnet 60 is radial direction periodical magnetic filed, and relay is electric with Hall element 61 and driving respectively
Machine 31 connects, and when driving shaft 41 runs well, Hall element 61 detects the field homogeneity change of annular magnet 60, relay
There is not action, remain turned on;When machine overload causes driving shaft 41 to stop operating, magnetic field no longer changes, Hall unit
When part 61 detects the stopping change in magnetic field, relay disconnects, protect motor 31 not because during overload electric current constantly increase and
Burn.
The present invention, the middle part of frame 10 is provided with dividing plate 12, is divided into upper cavity and lower chamber, driving means by inside frame 10
30 and reducing mechanism 40 be arranged in epicoele body, on dividing plate 12 be located at reducing mechanism 40 lower section be provided with discharging opening, in cavity of resorption body
It is provided with the debris box 20 for collecting hard disk chip towards discharging opening, the chip after reducing mechanism crushing hard disk timely falls
Enter in debris box 20, and periodically outwell.
The side of frame 10 is provided with safety door, and safety door is provided with to be opened for the fine motion starting or closing described motor
Close, when safety door is in opening, such as when putting into disk or picking and placeing debris box 20, microswitch disconnects, and drives electricity
Machine 31 suspends operating, substantially increases safety, it also avoid because non-working person to open the safety that safety door causes hidden by mistake
Suffer from.
The present invention, using chain drive, accurately, multigroup profile of tooth cutterhead being oppositely arranged can for compact conformation, transmission
