Abstract
The utility model discloses an automatic constant gap deviation rectifying device of roll shafts of a roll press. The deviation rectifying device comprises power devices, the roll shafts, hydraulic cylinders, hydraulic integrated valve blocks and connecting devices, wherein, the power devices are connected with the roll shafts through the connecting devices; two sets of power devices, two sets of roll shafts and two sets of connecting devices are respectively provided; the hydraulic integrated valve blocks comprise a left hydraulic integrated valve block (4) and a right hydraulic integrated valve block (7); the hydraulic cylinders comprise a left hydraulic cylinder (1) and a right hydraulic cylinder (10); two pressure valves, two pressure reducing valves and two relief valves are respectively arranged on the left hydraulic integrated valve block (4) and the right hydraulic integrated valve block (7); and the pressure valves, the pressure reducing valves and the relief valves are communicated with the hydraulic cylinders through pipelines. Through the technical scheme, rolls gap can be regulated within a set range, thereby guaranteeing the stability of the material throughput in the roll press and enabling a system to run better.
Description
Technical field
The utility model relates to rolling equipment, is specifically related to the large-scale roller press of the various materials of a kind of grinding.
Background technology
The conventional roll press has adopted " constant pressure " control; when operating pressure is provided; has certain buffer capacity; by foreign matter or iron block the time; protect roll squeezer injury-free effectively; the constant pressure system guarantees all mill feed materials all through extruding, thereby overcomes the fluctuation of mill feed material grindability, the quality of stable prod.Its weak point is: when the material thickness inhomogeneous, roll gap changes when violent, actual working pressure is acute variation thereupon, " constant pressure " working method is in order to guarantee that operating pressure is stable, its hydraulic system with frequent starting, greatly reduces the reliability and the life-span of hydraulic system with frequent release, oil pump and hydraulic valve piece.For guaranteeing that mill feed material is all through extruding, " constant pressure " working method has been abandoned the control of (comprising that roll gap size and roll gap are poor) of normal working roll seam, can not normally rectify a deviation, it is effectively stable to make work roll gap size can not get, cause the roll squeezer throughput not stablize, occur big fluctuation easily, influence the product that reaches up to standard of system.
The utility model content
The utility model has overcome the deficiencies in the prior art, and the roll squeezer of the seam of the perseverance automatically correction that a kind of thruput is stable, mill efficiency is high, the life-span is long is provided.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of roll squeezer comprises power set, roll shaft, hydraulic cylinder, hydraulic integrated valve block and jockey, and power set are connected by jockey with roll shaft, and wherein power set, roll shaft and jockey respectively are two covers; Hydraulic integrated valve block is divided into left hydraulic integrated valve block, right hydraulic integrated valve block; Hydraulic cylinder comprises left hydraulic cylinder and right hydraulic cylinder; Be respectively arranged with pressurizing valve, pressure-reducing valve and an overflow valve on left side hydraulic integrated valve block, the right hydraulic integrated valve block, pressurizing valve, pressure-reducing valve and overflow valve are communicated with hydraulic cylinder by pipeline.
Compared with prior art, the beneficial effects of the utility model are:
Can be sewn in the scope of a setting by dancer rools by the technical program, guaranteed the stable of thruput in the roll squeezer, thereby system is better moved.
Description of drawings

Fig. 2 is the utility model hydraulic integrated valve block structure for amplifying schematic diagram.
Fig. 3 is the A-A ' schematic diagram of this Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As Fig. 1, Fig. 2 and shown in Figure 3, the permanent automatically seam deviation correcting device of a kind of roll squeezer roll shaft, comprise power set, roll shaft, hydraulic cylinder, hydraulic integrated valve block and jockey, power set are connected by jockey with roll shaft, and wherein power set, roll shaft and jockey respectively are two covers; Hydraulic integrated valve block is divided into left and right hydraulic integrated valve block 4,7; Hydraulic cylinder 11 comprises left hydraulic cylinder 1 and right hydraulic cylinder 10; Left side integrated valve block 4 is provided with a left side and adds pressure electromagnetic valve 2, left vacuum solenoid valve 3 and left overflow valve 5, and a left side adds pressure electromagnetic valve 2, left vacuum solenoid valve 3 and left overflow valve 5 and is communicated with left hydraulic cylinder 1 by pipeline; Right integrated valve block 7 is provided with the right side and adds pressure electromagnetic valve 9, right vacuum solenoid valve 8 and right overflow valve 6, and the right side adds pressure electromagnetic valve 9, right vacuum solenoid valve 8 and right overflow valve 6 and is communicated with right hydraulic cylinder 10 by pipeline;
This device is on the basis of existing control mode, set up " permanent roll gap " control mode, at first set predetermined pressure, by to a left side, the right side adds pressure electromagnetic valve 2,9, left side vacuum solenoid valve 3, right vacuum solenoid valve 8, overflow valve 5,6 control, make roll squeezer be stabilized in work in certain roll gap scope, its principle is: ordinary production roll gap (permanent roll gap) is made as X 1, actual roll gap is made as X 2, roll gap correction difference is Δ X, when the value of left side X2-X1 during greater than Δ X, a control left side adds pressure electromagnetic valve 3 action, to the adjusting of pressurizeing of left hydraulic jack 1 pressure, thereby the position deviation of movable roll is corrected; When the value of right side X2-X1 during greater than Δ X, the control right side adds pressure electromagnetic valve 9 actions, to the adjusting of pressurizeing of right hydraulic jack 10 pressure, thereby the position deviation of movable roll is corrected; When left side or right side pressurization during, control system output alarm greater than the setting value of overflow valve 5,6, reduce the pressure of a corresponding side simultaneously, regulate the left and right sides roll gap at setting range, guarantee that the throughput of roll squeezer is stable, the operation of assurance system simultaneously is normal.
