Abstract
The invention discloses a milling device for flaky metallic soft magnetic micro powder granules. The milling device comprises a driving milling roll and a driven milling roll which are arranged in a hopper side by side, roll surfaces of the driving milling roll and the driven milling roll fit each other, two ends of one cylindrical roll surface are connected with flared tapered roll surfaces respectively, two ends of the other cylindrical roll surface are connected with contracting tapered roll surfaces respectively, the roll surfaces of the driving roll and the driven roll are attached to each other, and the driving roll and the driven roll rotate reversely. The granule milling device is applicable to basic characteristics that binding force among the flaky metallic soft magnetic micro powder granules is small and the granules are easy to break into powder. According to arrangement of the roll surfaces of the milling rolls, the granules can be driven to the middles of the milling rolls to be crushed centralizedly, the milling device is high in breakage rate, easy to operate, small in noise and less in raising dust, and the requirements for mass production and environmental protection are met.
Description
Technical field
The present invention relates to a kind of rolling crushing device, be specifically related to a kind of rolling crushing device of flakey soft magnetic metal micro mist granule material.
Background technology
REID (RFID) is as the core link realizing internet, Internet of Things article identification, its product need use flexible magnetic sheet to realize, flexible magnetic sheet is made up of very thin, that thickness is below 1 μm soft magnetic metal micro mist, can be used to absorbing high-frequency electromagnetic interference wave, and effectively can prevent the interference of metal object reflection to reader identification RFID label tag, at Internet of Things communication channel, it can improve the effective depth of antenna, suitably increases communication distance.
Soft magnetic metal powder after flaking device completes flattening through feed liquid separator, after most abrasive media is separated, again through super-dry process, after residual abrasive media is fully volatilized, material powder has part to produce the phenomenon that hardens, clump together granular particle, a granular solid matter must be rolled over and be broken into pulverous semi-finished product, produce to enter next procedure.Because the adhesion of this granular solid matter is not strong, use traditional crusher totally unnecessary, and the noise produced is large, airborne dust is many, is unfavorable for the requirement of environmental protection and labour protection.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provide a kind of granule material thoroughly broken, noise is little, and crushing device rolled over by the flakey soft magnetic metal micro mist granule material that dust is few.
Technical scheme: crushing device rolled over by a kind of flakey soft magnetic metal micro mist granule material, to comprise in hopper side by side initiatively roll over roller and driven rolling roller, roll surface is suitable, one connects for cylindrical roll surface two ends the taper roll surface extended out respectively, another connects the taper roll surface of contraction respectively for cylindrical roll surface two ends, and described roller and the driven rolling roller roll surface of initiatively rolling over is fitted and followed and rotate backward.Roll over the rightabout motion between roller, the granule material of soft magnetic metal micro mist is involved in, flow out from the gap that roller is rolled over, the geometry complementary fit that two rollers are rolled over, the axial thrust load produced in the spreading process of granule material like this, makes material move to intermediate cylindrical, two ends can not be dispersed to, avoid end face to be blocked under about the pressure of two rollers rollings, granule material is extruded, to destroy granule material structure powdering.
Further, described power transmission shaft of initiatively rolling over roller and driven rolling roller is by adjustable bearing block support of initiatively rolling over the spacing of roller and driven rolling roller, make to keep suitable gap between two rolling rollers, distance adjustment between two rollers is usually at about 1.2 μm, so both the group's of guarantee bulk goods was pulverized, and did not cause again and expected and adhesion again after rolling over.
Further, describedly initiatively roll over roller and driven rolling roller is made up of structural alloy steel, after heat treatment hardness reaches more than HRC60, and its quality of fit all needs II class precision.This ensure that the linear contact of roll surface, increase wearability simultaneously, extend the service life of roller.
In order to prevent dust recycling, the charging aperture of described hopper is sealed by seal.
Beneficial effect: the adhesion that the present invention is applicable between flakey soft magnetic metal micro mist granule is little; be easy to the basic characteristics being broken into powder; can drive according to the layout diplomatic corps pellet of rolling over roller roll surface and carry out concentrating pulverizing in the middle part of rolling roller; its percentage of damage is high; easy and simple to handle; noise is little, and airborne dust is few, thus reaches the requirement of large-scale production and the requirement of environmental protection.

Detailed description of the invention
Below technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described embodiment.
Embodiment: crushing device rolled over by a kind of flakey soft magnetic metal micro mist granule material, as shown in Figure 1, 2, comprise hopper 2, belt 4 takes turns 3, belt 4, motor 5, adjustment screw 6, bearing 7, bearing block 8, initiatively roll over roller 9, driven rolling roller 10, valve 11, tremie pipe 12, frame 13.What be provided with horizontal Tile in hopper 2 initiatively rolles over roller 9 and driven rolling roller 10, wherein, the roll surface of initiatively rolling over roller 9 and driven rolling roller 10 is syllogic, initiatively rolling over roller 9 is that intermediate cylindrical roll surface two ends are connected to the conical surface extended out respectively, the roll surface of driven rolling roller 10 is the conical surface that the intermediate cylindrical roll surface two ends suitable with it are connected to contraction respectively, two roll over the laminating of roller roll surface, composition syllogic gap, and raw material is rolled over broken outflow from gap.The power transmission shaft of initiatively rolling over roller 9 and driven rolling roller 10 stretches out outside hopper 2, is fixed in frame 13 by bearing block 8 through bearing 7.Bearing block 8 is provided with the adjustment screw 6 of precession, with the distance between the bearing block 8 regulating two rolling rollers, ensures that the gap of initiatively rolling between roller 9 and driven rolling roller 10 is at about 1.2 μm.Frame 13 is fixed with motor 5, by the belt 4 on motor 5 take turns 3 and initiatively the belt 4 of rolling on roller 9 power transmission shaft take turns 3 by belt 4 transmission, driving is initiatively rolled over roller 9 and is rotated; And motor 5 is taken turns the driven rolling roller 10 of 3 drive by belt 4 and is rotated backward.
The charging aperture 1 at hopper 2 top has the detachable connection of lid, fixes with seal, is connected and airtight between conveying mechanism with charging aperture with transparent pipe, to observe charging situation, and prevents material dissipation.All need between remaining part and hopper 2 to adopt dust seal, leak to prevent dust.The granule material of soft magnetic metal micro mist enters hopper 2 by the charging aperture 1 at hopper 2 top, concentrates on the conical lower portion of rolling over and falling into hopper 2 after the extruding of roller medium position is pulverized, is flowed out after gathering by valve 11 from tremie pipe 12.The granule material percentage of damage of apparatus of the present invention to flakey soft magnetic metal micro mist is high, processes more rapidly and efficiently, and long service life.
As mentioned above, although represented with reference to specific preferred embodiment and described the present invention, it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite not departing from claims definition, various change can be made in the form and details to it.
