Description
Technical field
The utility model relates to the material grinding equipment, specifically is the roller grinding machine that a kind of end is put multi roll.
Background technology
On August 7th, 1991, " 90100329.8 " number patent application specification of bulletin disclosed a kind of cylindrical-roll grinder, and this cylindrical-roll grinder is a kind of " end is put grinding roller formula structure ", and promptly grinding roller is only realized the location by the roll shaft of one end.This roller grinding machine, mill tube and mill tube driving mechanism are arranged, grinding roller is arranged in the mill tube, there is end cap at the two ends of mill tube, mill tube distolateral has feed arrangement and discharging opening, and an end of grinding roller connects a roll shaft, and the outer section of roll shaft is stretched out end cap, be connected with bearing, the pressing mechanism that acts on grinding roller is set on the roll shaft shaft part in the bearing inboard or the outside.This cylindrical-roll grinder has the embodiment of single group grinding roller and many group grinding rollers.The structure of single group grinding roller is at same roll shaft upper edge axis a plurality of short shape grinding rollers to be set, the combination of a plurality of short shape grinding rollers and axial complete break-in face of mill tube inwall formation; The structure of many group grinding rollers is that by having several oil cylinders on the roll shaft, each oil cylinder is all given two or more short shape grinding roller pressurizations separately and milled; In addition, be provided with supporting member at the position vertically downward of mill tube.The deficiency that this cylindrical-roll grinder exists is: because single group grinding roller and mill tube only constitute an axial complete break-in face, so production efficiency is lower; And organize grinding roller more, then complex structure is difficult to implement in reality is produced, and the manufacturing cost height; In addition, its supporting member just plays the supporting constraint effect to mill tube direction vertically downward, other direction along circumference then is in unconfined free state, therefore, in the running, mill tube easily produce beat or vibration and noise, particularly mill tube in when the multiple roll operation is arranged, easily produce out-of-balance force, then can aggravate these phenomenons.
Summary of the invention
The purpose of this utility model provides a kind of can enhancing productivity effectively, and running stably end put the multi roll grinding machine.
The technical solution of the utility model is, mill tube and mill tube driving mechanism are arranged, there is end cap at the two ends of mill tube, and mill tube distolateral has feed arrangement and discharging opening, and grinding roller is arranged in the mill tube, one end of grinding roller connects a roll shaft, outer section of roll shaft is stretched out end cap, is connected with bearing, and the bearing outside or inboard roll shaft shaft part are provided with the pressing mechanism that acts on grinding roller on this roll shaft, at least be provided with two grinding rollers that distribute along the mill tube circumferencial direction in the mill tube, be provided with the supporting system of constraint mill tube circumferencial direction.
The further structure of technical solutions of the utility model is that the grinding roller that is provided with two in the described mill tube at least is uniform along the mill tube circumferencial direction.
Technique effect of the present utility model is:
1, owing to is provided with two grinding rollers that distribute along the mill tube circumferencial direction in the mill tube at least, promptly constitute two or more axial complete break-in faces with mill tube, the moving circle of mill tube revolution can be realized twice or twice above milling material, therefore can enhance productivity effectively, reduces operating cost.
2, each grinding roller is connected with a roll shaft respectively, makes enforcement easy to manufacture and uses reliable.
3, owing to be provided with the supporting system of constraint mill tube circumferencial direction, therefore, can stop mill tube in operation process, to produce circular runout or vibration effectively, reduce noise, make mill tube stable operation, and can under high rotating speed, move, thereby further enhance productivity, also can under high rotating speed, reduce grinding roller pressure, and reach the output that is equal under the slow speed high pressure, reduce machine members and damage with effective force.In addition, run up and multiple roll also helps the processing of fine powder.
4, because two or more grinding rollers are uniform along the mill tube circumferencial direction, make each one of mill tube stressed evenly basic and be balanced, and the active force of grinding roller, do not act on supporting system and Equipment Foundations in theory, thereby friction and wearing and tearing and power consumption between minimizing mill tube and the supporting system, feasible operation is more stable, and reliability is higher.
