The technological scheme that its technical problem that solves the utility model adopts is: this paper cutter list pump biliquid pressing system, comprise the hydraulic system that oil hydraulic pump, oil cylinder vat, the little cylinder of oil cylinder and clutch oil cylinder are formed, it is characterized by: oil hydraulic pump is the simply connected oil hydraulic pump, the outlet end of simply connected oil hydraulic pump is connected with equilibrium valve, and first outlet of equilibrium valve is communicated with the little cylinder of oil cylinder; When equilibrium valve 9 actions, first outlet and second outlet of equilibrium valve 9 are communicated with the little cylinder 11 of oil cylinder, oil cylinder vat 10 and reduction valve 3 simultaneously, and the outlet of reduction valve is communicated with the filler opening of clutch oil cylinder.
Further be that the outlet end of simply connected oil hydraulic pump is connected with return line by relief valve.
Further be that the outlet end of simply connected oil hydraulic pump and the entry end of reduction valve are connected with return line by selector valve respectively.
Further be, the outlet of reduction valve connects clutch oil cylinder and return line by solenoid directional control valve, and the entry end of reduction valve is connected with the pressure relay of control electromagnetic switch valve events.
The beneficial effects of the utility model are: by being power source with the simply connected oil hydraulic pump, be arranged to two different pressure spans with the hydraulic system that reduction valve is incited somebody to action, satisfy to drive the needs of the paper cutter paper weight and the different oil liquid pressures of the strong plate of knife rest, the biliquid pressing system that has changed traditional paper cutter is with the be used as power mode in source of duplex oil hydraulic pump.Both simplified the structure like this, reduced the manufacturing cost of paper cutter again, reduced rate of fault, can be widely used in the transformation and the new product manufacturing of existing paper cutter.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure: oil purifier 1, oil hydraulic pump 2, reduction valve 3, selector valve 4, pressure relay 5, solenoid directional control valve 6, clutch oil cylinder 7, relief valve 8, equilibrium valve 9, oil cylinder vat 10, the little cylinder 11 of oil cylinder.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, paper cutter list pump biliquid pressing system of the present utility model is that with the something in common of existing paper cutter biliquid pressing system hydraulic system includes oil hydraulic pump 2, oil cylinder vat 10, the little cylinder 11 of oil cylinder and clutch oil cylinder 7.Its difference is that oil hydraulic pump 2 is the simply connected oil hydraulic pump, and the entry end of simply connected oil hydraulic pump is provided with oil purifier 1 usually, and the outlet end of simply connected oil hydraulic pump is connected with equilibrium valve 9, and first outlet of equilibrium valve 9 is communicated with the little cylinder 11 of oil cylinder; After the hydraulic oil in the little cylinder 11 of oil cylinder reaches certain pressure, equilibrium valve 9 actions, first outlet and second outlet of equilibrium valve 9 are communicated with the little cylinder 11 of oil cylinder, oil cylinder vat 10 and reduction valve 3 simultaneously, and the outlet of reduction valve 3 is communicated with the filler opening of clutch oil cylinder 7.
In order to guarantee that the oil pressure in oil cylinder vat 10, the little cylinder 11 of oil cylinder does not exceed setting pressure, the outlet end of simply connected oil hydraulic pump is connected with return line by relief valve 8.
For its oil cylinder vat 10, little cylinder 11 releases of oil cylinder are resetted, the entry end of the outlet end of simply connected oil hydraulic pump and reduction valve 3 is connected with return line by selector valve 4 respectively.Selector valve 4 can adopt the mechanical commutation valve, but adopts solenoid directional control valve to be more convenient for realizing automatic control usually.
Same reason resets in order to make its clutch oil cylinder 7 releases when hydraulic system is not worked, and the outlet of reduction valve 3 connects clutch oil cylinder 7 and return line by solenoid directional control valve 6.Simultaneously, the entry end of reduction valve 3 is connected with the pressure relay 5 of control solenoid directional control valve 6 actions, is used for the working state of solenoidoperated cluthes oil cylinder 7.
In paper cutter list pump biliquid pressing system of the present utility model, during hydraulic work system, the passage that hydraulic oil refluxes has been blocked in selector valve 4 energising commutations.Hydraulic oil in the oil sump uses for the simply connected oil hydraulic pump after passing through oil purifier 1 filtration, and the hydraulic oil with rated pressure that flows out from the simply connected oil hydraulic pump exports the little cylinder 11 of inflow oil cylinder through first of equilibrium valve 9, drives the paper weight motion.After the hydraulic oil in the little cylinder 11 of oil cylinder reaches certain pressure, equilibrium valve 9 actions, second outlet of equilibrium valve 9 is communicated with oil cylinder vat 10, this moment, hydraulic oil was just simultaneously to little cylinder 11 of oil cylinder and oil cylinder vat 10 fuel feeding, after the hydraulic oil in the oil cylinder vat 10 reaches certain pressure, reduction valve 3 work, pressure relay 5 actions simultaneously, send the 6 energising commutations of electrical signal control solenoid directional control valve, its hydraulic oil with setting pressure just constantly flows in the clutch oil cylinder 7 this moment, drives the knife rest wallboard motion of paper cutter.When the hydraulic oil in oil cylinder vat 10 and the little cylinder 11 of oil cylinder surpassed setting pressure, the pressure oil that pumps from the simply connected oil hydraulic pump just flowed back to fuel tank through relief valve 8 through return line.
When hydraulic system is not worked, selector valve 4 and solenoid directional control valve 6 are in initial position shown in Figure 1, hydraulic oil in the fuel tank uses for the simply connected oil hydraulic pump after filtering by oil purifier 1, and the hydraulic oil with oil pump rated pressure that flows out from the simply connected oil hydraulic pump flows back to fuel tank through selector valve 4.Simultaneously, oil cylinder piston is got back to initial position under the effect of external force, and the hydraulic oil in the little cylinder 11 of oil cylinder vat 10 and oil cylinder flows back in the fuel tank by equilibrium valve 9, selector valve 4 respectively.Secondly, the piston in the clutch oil cylinder 7 is under the effect of spring force, and driven plunger is got back to initial position, and hydraulic oil flows back to fuel tank through solenoid directional control valve 6 in the clutch oil cylinder 7 simultaneously.
