The open mill comprises a machine body, a front roller and a rear roller arranged on the body, and a base for supporting the front roller and the rear roller, wherein the front roller and the rear roller are connected with the base through sliding bearing seats; a pair of cams for driving the bearing blocks to slide is arranged in the base; the cams are connected through a synchronous transmission shaft and are connected with piston rods of pressure cylinders through slide blocks; a pressure adjusting screw is arranged at the other end of each pressure cylinder; a safety valve and an oil injection valve are arranged on each pressure cylinder. By virtue of the open mill with the overload protection distance adjusting device, the roller spacing between the front roller and the rear roller is accurately adjusted by a double-cam mechanism, so that the parallelism degree of the two rollers is accurately guaranteed, and the milling efficiency is improved; meanwhile, the rollers are subjected to overload protection by a pair of small pressure cylinders; the open mill has the advantages of small size, low cost and good protective effect.
Description
Technical field
The utility model relates to a kind of mechanical roll-setting gear, particularly relates to a kind of mill with overload protection roll-setting gear.
Background technology
Mill is mainly used in, in mixing process, sizing material is added to sulphur, compressing tablet processing; and when sizing material is really up to the mark owing to dealing with improperly; carrying out compressing tablet processing can produce and destroy equipment; existing roll adjustment mode has two kinds: mechanical roll adjustment and hydraulic distance-regulating; wherein mechanical roll adjustment cannot provide overload protection; and existing hydraulic distance-regulating carries out roll adjustment by the direct driving roller bearing of hydraulic cylinder; therefore need extra a set of fluid power system that increases; equipment cost is increased greatly, be unfavorable for large-scale promotion use.
Utility model content
Main purpose of the present utility model is to address the above problem and is not enough, provides a kind of by mechanical cam roll adjustment, and has the mill of overload protection function.
The technical solution of the utility model is for achieving the above object:
A kind of mill with overload protection roll-setting gear, comprise body, be arranged on the front and back roller on body, and the pedestal that supports front and back roller, described front and back roller is connected with pedestal by bearing block slidably, in described pedestal, be also provided with the cam of a pair of driving shaft bearing slip and be fixed on the pressure cylinder on pedestal, cam is connected with the piston rod of pressure cylinder by slide block, and the other end of described pressure cylinder is provided with a pressure regulating screw being fixed on pedestal;
Between described cam, by a Synchronous Transmission axle, be connected, one end of Synchronous Transmission axle is connected with distance-adjusting motor, when synchronizing shaft rotates, drives two cams synchronously to rotate, and bearing block is moved along cam contour, and then front and back roller is carried out to roll adjustment;
Described pressure cylinder is provided with safety valve and fuel feeding valve.
Further, a turbine and worm transmission mechanism is housed between described distance-adjusting motor and Synchronous Transmission axle, this mechanism to Synchronous Transmission axle, and has the effect of deceleration by the transmission of torque of distance-adjusting motor.
Further again, a Pressure gauge is also housed, for showing the oil pressure size in pressure cylinder on described pressure cylinder.
The beneficial effects of the utility model are; adopt double cam mechanism to carry out fine adjustment to the roll spacing of front and back roller; guarantee very accurately the depth of parallelism of two rollers; improved the efficiency of refining glue; increase a pair of small pressure cylinder pair roller barrel simultaneously and carried out overload protection; have volume little, cost is low, protects effective advantage.
Accompanying drawing explanation
A kind of top plan view with the mill of overload protection roll-setting gear of Fig. 1 the utility model;
Fig. 2 is the B-B face cutaway view of Fig. 1;
Shown in figure: 1, body 2, blanket roller 3, rear roller 4, pedestal 5, bearing block 6, cam 7, slide block 8, Synchronous Transmission axle 9, pressure cylinder 10, pressure regulating screw 11, safety valve 12, distance-adjusting motor 13, fuel feeding valve 14, turbine and worm transmission mechanism 15, Pressure gauge.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1:
As depicted in figs. 1 and 2, a kind of mill with overload protection roll-setting gear, comprises body 1, is arranged on the front and back roller 2,3 on body 1, and the pedestal 4 that supports front and back roller 2,3.The two ends of front and back roller 2,3 are passed through slidably bearing block 5 and are connected with pedestal 4, and wherein, blanket roller 2 conducts are roller fixedly, does not change with the relative position of pedestal 4, and rear roller 3 can slide along pedestal 4 as its bearing block 5 of adjusting roller.In pedestal 4, place near rear roller 3, also be provided with the cam 6 that a pair of driving shaft bearing 5 is slided, the sidewall contact of the outline of cam 6 and bearing block 5, cam 6 is also connected with the piston rod of pressure cylinder 9 by slide block 7, in pressure cylinder 9, hydraulic oil is housed, at the other end, be provided with a pressure regulating screw 10, pressure regulating screw 10 is fixed on pedestal 4, conflict on the active cover of pressure cylinder 9 in one end, when rotation is during pressure regulating screw 10, pressure regulating screw 10 promotes the active cover motion of pressure cylinders 9, to pressure cylinder 9 adjusting of pressurizeing.
Between cam 6, by a Synchronous Transmission axle 8, be connected, one end of Synchronous Transmission axle 8 is connected with distance-adjusting motor 12, a turbine and worm transmission mechanism 14 is housed between distance-adjusting motor 12 and Synchronous Transmission axle 8, this mechanism to Synchronous Transmission axle 8, and realizes deceleration by the transmission of torque of distance-adjusting motor 12, when Synchronous Transmission axle 8 rotates, drive two cams 6 synchronously to rotate, bearing block 5 is moved along cam 6 profiles, and after driving, roller 3 slides, and then realizes the roll adjustment to front and back roller 2,3.
Safety valve 11 and fuel feeding valve 13 are housed on pressure cylinder 9, when having foreign matter to enter between front and back roller 2,3, pressure between roller increases, and by cam 6 and slide block 7, pressure is passed to pressure cylinder 9, when pressure cylinder 9 internal pressures increase, safety valve 11 emptyings, retract piston rod, before and after increasing, the spacing of roller 2,3, has avoided the destruction to roll-setting gear.
