Abstract
The invention relates to a leather roller casing unloading machine, comprising a rack, and a motor, a hydraulic pump and a leather roller suppression device which are installed on the rack. The hydraulic pump is connected with the leather roller suppression device by a hydraulic pipe which is also provided with a variable flow solenoid valve. The variable flow solenoid valve can cause high-pressure liquid coming from the hydraulic pump to flow to different hydraulic cavities of a hydraulic cylinder so as to change the moving direction of a piston rod. The leather roller suppression device comprises the hydraulic cylinder and the piston; a limit trigger switch is arranged at a neighboring position; and the limit trigger switch can control the variable flow solenoid valve by a circuit. When the piston rod reaches a set stroke position, the limit trigger switch is gotten through, then, the variable flow solenoid valve works and changes the hydraulic cavity, to which the high-pressure liquid flows.
Description
Technical field
The present invention relates to hydraulically powered mechanical device, relate in particular to the hydraulic type roller and be inserted in and dismounting device.
Background technique
On spinning machinery, because the sliver of feeding drafter has certain thickness,, do not damage fiber again in order to grip fiber equably, need use roller, roller is coated with flexible material on the general surface.This elasticity coating is referred to as cot (or sebific duct), and cot produces the compressibility distortion under the effect of pressure, fiber is evenly gripped.
Roller is the critical component of textile manufacturing machine, is made up of the elastic material that roller bearing and outside coat.In use, the elastic material of outside weares and teares easily, needs often to change, and will use the roller sleeve unloading machine when changing elastic material.
" 98222059.6 " number patent disclosure a kind of " Apparatus for mounting/dismounting rubber roller ", be characterized in that promoting cylinder push-rod with cylinder stretches out cylinder, the other end fixed installation bracket at platform, bracket is used for clamping roller bearing, cylinder push-rod can also have been mentioned a kind of roller sleeve unloading machine of hydraulic type with roller lagging material and roller bearing consolidation in this patent document.The roller sleeve unloading machine of these cylinder types or hydraulic type all needs manually to control push rod, and grasping the degree of depth that roller is pressed into, and push rod moves in the horizontal direction, and the polarization of push rod front end is poor.
Summary of the invention
(1) technical problem that will solve
To be solved by this inventionly be that roller sleeve unloading machine push rod polarization is poor, Stroke Control is not good, the bad technical problem of effect in the automation process.
(2) technological scheme
In order to solve this technical problem, the present invention takes following scheme:
The invention provides a kind of roller sleeve unloading machine, comprise frame and the motor, oil hydraulic pump, the roller pressure setting that are installed on the frame, described oil hydraulic pump is connected by hydraulic tube with the roller pressure setting, and the unsteady flow solenoid valve is installed on the described hydraulic tube.Described roller pressure setting comprises oil hydraulic cylinder, piston rod, and the piston portion of piston rod afterbody is divided into propelling chamber and rollback chamber with oil hydraulic cylinder inside, advances chamber and rollback chamber to be connected to the unsteady flow solenoid valve by hydraulic tube.The unsteady flow solenoid valve can make the highly pressurised liquid from oil hydraulic pump flow to propelling chamber and rollback chamber respectively in different time, to change the moving direction of piston rod.
Wherein, described piston rod is attached with spacing touch switch, and spacing touch switch is by circuit control unsteady flow solenoid valve.When highly pressurised liquid flowed to the propelling chamber of oil hydraulic cylinder, piston rod was released, and when piston rod arrived the travel position of setting, spacing touch switch was connected, unsteady flow solenoid valve work this moment, and highly pressurised liquid flows to the rollback chamber of oil hydraulic cylinder, and piston rod is return.
Wherein, on the described unsteady flow solenoid valve drain tap is arranged, unloading valve is connected on the described drain tap, and on the hydraulic tube that described oil hydraulic pump is connected relief valve and pressure-display device is installed, and relief valve remains between 0.5 to 2.5 MPa fluid pressure.When the fluid pressure that pumps when oil hydraulic pump is excessive, relief valve can flow out a part of liquid, and pressure is remained in the OK range, when piston rod is finished once advance and retreat and kept initial position motionless, oil hydraulic pump does not quit work, and the highly pressurised liquid that pump this moment also flows back in the fuel tank by relief valve.
Wherein, described piston rod is the above-below direction motion.When piston rod was above-below direction, the piston rod front end can thereby deviation not occur because of the former of gravity, and positioning performance is better.
Wherein, on the described frame operating table is installed, operating switch is installed on the operating table, described frame lower end is equipped with foot switch.Whenever press the next operation switch, piston rod comes and goes operation once, and foot switch can make the operator press switch in hand loading and unloading roller.
(3) beneficial effect
1, the unsteady flow solenoid valve can make the different hydraulic pressure cavity that flow to oil hydraulic cylinder from the highly pressurised liquid of oil hydraulic pump, to change the moving direction of piston rod.
2, spacing touch switch is by circuit control unsteady flow solenoid valve.When piston rod arrives the travel position of setting, will connect spacing touch switch, this moment, the work of unsteady flow solenoid valve changed the hydraulic pressure cavity that highly pressurised liquid flows to.
When 3, the fluid pressure that pumps when oil hydraulic pump was excessive, relief valve can flow out a part of liquid, and pressure is remained in the OK range.
When 4, piston rod was above-below direction, the piston rod front end can thereby deviation not occur because of the former of gravity, and positioning performance is better.
5, whenever press the next operation switch, piston rod comes and goes operation once, and the operator can press switch according to the qualification of oneself operating like this.Frame lower is equipped with foot switch, and foot switch can make the operator press switch with pin in hand loading and unloading roller.
