Existing fiberizer is divided according to the difference of its abrasive material workpiece shape, mainly comprises disc type, circular cone type and column type three major types.With the disc type is example, its abrasive material workpiece mainly comprises movable grinding disc and static cutting disk two big parts, when movable grinding disc is rotated by the arbor work of drawing, there are the very big sliding friction of resistance each other in movable grinding disc and static cutting disk, cause power consumption too high, cause the temperature rise of abrasive material workpiece too fast thus, spillage of material is serious, shorten service life, must often change renewal.For timely cooling, the grinding charge material also has to select water-cooled slurry for use, and operating efficiency is lower.And, because the interference of friction too far, movable grinding disc and static cutting disk contacting each other just can not be very tight, ground material just can only rely on the corner angle of its groove groove flank of tooth to shred, and in fact the stranding mill effect in the middle of the flank of tooth can only play miscellaneous function in default of the support of contact pressure.Therefore, the mode that grinds of existing fiberizer mainly is to cut mill, is difficult to evenly ground material fitly, and machine performance is difficult to strengthen.
Summary of the invention
The abrasive material workpiece too fast technical barrier of the excessive power consumption that causes of sliding friction spillage of material too high and that cause thus each other when solving existing fiberizer work running the invention provides a kind of in the hope of enhancing machine performance, the fiberizer of increasing work efficiency.
For solving the problems of the technologies described above, technical scheme of the present invention is: fiberizer, comprise first mill and second mill in relative rotation, and also comprise:
Middle mill is installed between described first mill and second mill, comprises the awl roller along middle mill circumferential arrangement, and the small end of described awl roller is inside;
The working surface of described first mill and second mill contacts with the awl roller of described middle mill.
As optimized technical scheme, described middle mill comprises millrind, and described awl roller circumferential arrangement is on described millrind.
As to improvement of the technical scheme, one in described first mill and second mill is movable grinding disc, and another is a static cutting disk.
As to improvement of the technical scheme, described first mill and second mill are two opposite movable grinding discs of direction of rotation.
As to improvement of the technical scheme, described in the middle of the millrind of mill fixedly install.
As to improvement of the technical scheme, described in the middle of the millrind of mill rotate and be provided with.
Owing to adopted technique scheme, when first mill and second mill are being drawn when relatively rotating by arbor, awl roller rotation in the middle of must driving on the mill, the awl roller running of just on the contact working face of mill, do rolling like this, first mill and second mill sliding friction between the two will be transformed between first mill, middle mill and the second mill three by boring the rolling friction of roller in the fiberizer so will have now; Can significantly reduce power consumption on the one hand, the lightening material loss increases the service life, and increases work efficiency; On the other hand; because awl roller One's name is legion; in case high speed scroll running; as long as material enters in the fiberizer; therefore the awl roller that will be run up one by one weight over and over again pulverizes, and main defibrination mode of the present invention is to mill, easily even ground material fitly; the protection fibre length, performance significantly strengthens than existing material grinder.

Fig. 2 is the front view of middle mill.
For the ease of observing, Fig. 1 is the drafting that spaces out of first mill, middle mill and second mill, and when real work, their threes mesh and contact very closely; The drawn arrow indication of Fig. 1 material traffic direction; Among the figure: the 1-arbor; 2-first mill; Mill in the middle of the 3-; 4-bores roller; The 5-millrind; 6-groove groove; 7-bores roll shaft; 8-discharging direction; The 9-charging aperture; 10-second mill.
The specific embodiment
As shown in Figure 1 and Figure 2, well-known components such as body and pressue device have been omitted among the figure.The fiberizer of present embodiment comprises first mill 2 and second mill 10 in relative rotation, first mill 2 is a movable grinding disc in the present embodiment, and by arbor 1 driven rotary, second mill 10 is a static cutting disk, the center of second mill 10 is provided with charging aperture 9, and the fiberizer of present embodiment also comprises:
Middle mill 3 is installed between described first mill 2 and second mill 10, comprises millrind 5, in the middle of described millrind 5 upper edges mill 3 12 awl rollers 4 circumferentially are installed, the small end of described awl roller 4 is inside; Described awl roller 4 circumferentially is distributed on the described millrind 5.
The working surface of described first mill 2 and second mill 10 closely contacts with described awl roller 4.
In the present embodiment, the millrind 5 of described middle mill 3 rotates and is provided with, and promptly described middle mill 3 is located by the clamping of described first mill 2 and second mill 10.
