Abstract
The invention discloses an open mill with an overload protection distance adjusting device. The open mill comprises a body, a front roller and a rear roller arranged on the body, and a base for supporting the front and rear rollers, wherein the front and rear rollers are connected with the base through sliding bearing blocks; a pair of cams 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. The roller spacing between the front and rear rollers 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, and the open mill has the advantages of small size, low cost and good protective effect.
Description
Technical field
The present invention relates to a kind of mechanical roll-setting gear, particularly relate 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 in the time that 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 additionally to increase a set of fluid power system; equipment cost is increased greatly, be unfavorable for that large-scale promotion is used.
Summary of the invention
Main purpose of the present invention 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.
Technical scheme of the present invention 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 of support front and back roller, described front and back roller passes through slidably bearing block and is connected with pedestal, 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, be connected by a Synchronous Transmission axle, one end of Synchronous Transmission axle is connected with distance-adjusting motor, in the time that 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 invention has the beneficial effects as follows; adopt double cam mechanism to carry out fine adjustment to the roll spacing of front and back roller; ensure very accurately the depth of parallelism of two rollers; improve 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.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention 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 supports the pedestal 4 of front and back roller 2,3.Before and after the two ends of roller 2,3 be connected with pedestal 4 by bearing block 5 slidably, wherein, blanket roller 2, as fixing roller, does not change with the relative position of pedestal 4, rear roller 3 can slide along pedestal 4 as its bearing block 5 of adjusting roller.In pedestal 4, near the place of 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, be provided with a pressure regulating screw 10 at the other end, pressure regulating screw 10 is fixed on pedestal 4, conflict on the active cover of pressure cylinder 9 in one end, when rotation is when pressure regulating screw 10, pressure regulating screw 10 promotes the active cover motion of pressure cylinder 9, to pressure cylinder 9 adjusting of pressurizeing.
Between cam 6, be connected by a Synchronous Transmission axle 8, 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, in the time that 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, in the time 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, in the time that 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.
A Pressure gauge 15 is housed on described pressure cylinder 9, when after pressure cylinder 9 emptyings, by the active cover of pressure regulating screw 10 compaction pressure cylinders 9, the oil pressure in pressure cylinder 9 is increased, and carry out the oil pressure size in controlled pressure cylinder 9 by observing Pressure gauge 15.
As mentioned above, given scheme content, can derive similar technical scheme in conjunction with the accompanying drawings and embodiments.In every case be the content that does not depart from technical solution of the present invention, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong to the scope of technical solution of the present invention.
