The specific embodiment

It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.

As shown in Figure 1, according to the roller mill of the application's embodiment mono-, comprise: housing 10, main shaft 20, drive unit 30, support 40, a plurality of grinding roller 50, mill 60 and base 70.

Housing 10 supports and is arranged on base 70, housing 10 comprises the first housing and is arranged on the second housing 10b in the first housing, charging aperture 11 is arranged on the top cover of housing, the first housing preferably includes top cover, be positioned at the first housing parts 10c of top and be positioned at the second housing parts 10a of below, and discharging opening 12 is arranged on the second housing 10b.Main shaft 20 is located in housing 10 rotationally, and one end of main shaft 20 is supported by base 70, and main shaft 20 can have the free end that is positioned at housing 10.Drive unit 30 drives and is connected with main shaft 20, for drive shaft 20, rotates, and drive unit 30 is arranged on base 70.Support 40 is arranged on main shaft 20, can synchronously rotate with main shaft 20, and each grinding roller 50 is installed in rotation on support 40 around himself axial line, that is to say that grinding roller 50 can either be around the center line revolution of main shaft 20, again around the center line rotation of grinding roller 50 self.It is upper and relative with a plurality of grinding rollers 50 positions that mill 60 is fixedly mounted on the second housing 10b, coordinated rolling of material with grinding roller 50.

In embodiment mono-, the supporting of main shaft 20 changes lower support into by upper support of the prior art, by base 70 supporting spindles 20 and drive unit 30 is arranged on base 70, can effectively reduce the height of equipment like this, reduce the center of gravity of equipment simultaneously and then improved stability and the reliability of equipment.

Preferably, between the first housing and the second housing 10b, be provided with positioner 81 and the first elastic device 82.Positioner 81 is for adjusting the gap of rolling of grinding roller 50 and mill 60, and positioner can be dog screw or cushion block, and the pressure of grinding roller 50 comes from the first elastic device 82.The flexible member of elastic device 82 can be spring, oil cylinder or cylinder etc.

Preferably, also the comprising of the roller mill of embodiment mono-: spreading disk 90, be arranged on main shaft 10 and with main shaft 10 and be synchronized with the movement, spreading disk 90 is positioned at the top of support 40.

The course of work of the roller mill of embodiment mono-is as follows:

Main shaft 20 is by drive unit 30 driven rotary, main shaft 20 drives support 40 rotations, periphery at support 40 is evenly equipped with more than 2 or 2 grinding rollers 50, grinding roller 50 is revolved round the sun with the axis around main shaft 20 by support 40, after being fed from charging aperture 11 by comminuting matter, fall on spreading disk 90, the spreading disk 90 of rotation will be spread to surrounding by comminuting matter, then fall on mill 60, between the flour milling of grinding roller 50 and mill 60, by dog screw or pad, adjusted the size in its gap, the grinding roller 50 revolving round the sun just can be pressed onto pulverized material, grinding roller 50 has just produced moment of friction with contacting of pulverized material, this moment of friction makes grinding roller 50 produce rotation, the grinding roller 50 that rotation is revolved round the sun again on the flour milling of mill 60 to carried out rolling repeatedly by comminuting matter, by the material after pulverizing, finally from discharging opening 12, discharged.Discharging opening 12 can be adjusted up and down by screw rod, thereby controls the height of discharging opening 12, and grinding roller 50 comes from elastic device 82 with the pressure of the flour milling of mill 60.

As shown in Figure 2, according to the roller mill of the application's embodiment bis-, comprise: housing 10, main shaft 20, drive unit 30, support 40, a plurality of grinding roller 50, mill 60 and base 70.Embodiment bis-is only with the difference of embodiment mono-, and main shaft 20 is supported by the top cover of base 70 and housing 10, the running that can make like this roller mill more steadily some and make the size of main shaft 20 smaller.The operation principle of the present embodiment and embodiment's mono-is basic identical, does not repeat them here.

As shown in Figure 3, according to the application's embodiment tri-, be only with the difference of embodiment bis-, drive unit 30 is moved to the top of housing 10 by the bottom of base 70, be conducive to like this maintenance of drive unit 30.The operation principle of the present embodiment and embodiment's mono-is basic identical, does not repeat them here.

As shown in Figure 4, according to the application's the roller mill of embodiment tetra-and the difference of above-described embodiment, be that grinding roller 50 is fixed on the mode on support 40.In embodiment tetra-, each grinding roller 50 is arranged on support 40 by rocker arm body, and rocker arm body comprises: free bearing 411, Rocker arm 4 12, stopping means 413 and elastic device 414.Free bearing 411 is arranged on support 40.Rocker arm 4 12 comprises interconnective the first arm 412a and the second arm 412b, and it is upper that grinding roller 50 is arranged on the first arm 412a, bends transition and connect between the first arm 412a and the second arm 412b, and the junction of the first arm 412a and the second arm 412b is hinged on free bearing 411.It is upper to regulate distance between the second arm 412b and support 40 to regulate the gap length between grinding roller 50 and mill 60 that stopping means 413 is connected to the second arm 412b, elastic device 414 has to the second arm 412b and applies the elastic component towards the pressure of support 40, and elastic device 414 can be for the pressurization to grinding roller 50.Main shaft 20 support patterns of the roller mill of embodiment tetra-can adopt the support pattern of above-mentioned arbitrary embodiment.

Particularly, in the present embodiment, stopping means 413 comprises the first bolt being located on Rocker arm 4 12 and is connected to the first nut on the first bolt, the bolt head of the first bolt is between Rocker arm 4 12 and support 40, the first nut is positioned at the top of Rocker arm 4 12, between the bolt head of the first bolt and Rocker arm 4 12, is selectively provided with one or more pads.Elastic device 414 comprises the second bolt being located on support 40 and Rocker arm 4 12 and is connected to the second nut on the second bolt, the bolt head of the second bolt is positioned at the below of support 40, the second nut is positioned at the top of Rocker arm 4 12, between the second nut and Rocker arm 4 12, is provided with elastic component.

Certainly, for example, as feasible mode; other multiple variation can also occur for the shape of rocking arm, positioner and elastic device and installation site; Chinese patent ZL99233773.9 discloses a kind of vertical roll grinder; the mounting means of its grinding roller 50 is similar to the mode of embodiment tetra-; but in this patent, positioner is placed on the bottom of support, and elastic device is placed in support lower annular recess.
