Embodiment
For clearer statement the present invention, the present invention is done further description below in conjunction with accompanying drawing.
Extremely shown in Figure 4 like Fig. 1; The present invention provides a kind of hot melt adhesive fluid pressure piston pump; Comprise unidirectional advance glue valve 1, piston pump seat 2, unidirectional plastic emitting valve 3 and motion cylinder block 4; Unidirectionally enter the upper end that glue valve 1, unidirectional plastic emitting valve 3 and motion cylinder block 4 are fixed on piston pump seat 2, motion cylinder block 4 is fixed in the unidirectional upside that advances glue valve 1 and unidirectional plastic emitting valve 3 successively.With closed, form a fluid chamber that has high pressure through unidirectional unlatching of advancing glue valve 1 and unidirectional plastic emitting valve 3 in the inside of piston pump seat 2.This fluid chamber is made up of four passages, and four passages comprise main passage 11, subaisle 12, upper channel 13 and lower channel 14.Upper channel 13 is arranged at the top and bottom of main passage 11 and subaisle 12 respectively with lower channel 14, and all is connected with main passage 11 and subaisle 12.Unidirectionally advance glue valve 2 and be made up of with jump ring 25 valve body 21, ripple pearl 22, spring 23, gland 24, valve body 21 is connected with ripple pearl 22, spring 23, gland 24 and jump ring 25 successively.Ripple pearl 22 can only be put into from of valve body 21, and can not drop out with the other end, and spring 23 is set on the ripple pearl, on spring, refills upper press cover 24, puts jump ring 23 and fuses with valve body 21.Unidirectional plastic emitting valve 3 is made up of valve body 32, ripple pearl 33, spring 34, gland 35, jump ring 36, cushion rubber and plug gland 38; Wherein, The quantity of cushion rubber is two; First cushion rubber 31 is arranged at the lower end of valve body 32, and second cushion rubber 37 is arranged between plug gland 38 and the jump ring 36, and jump ring 36 is connected with valve body 32 with gland 35, spring 24, ripple pearl 33 successively.Valve body is vertically disposed, and under working state not, the ripple pearl is being closed under the effect of gravity and Returnning spring, and the melten gel fluid can only flow into from valve inner from the valve body below, and is flowed out by the top of valve body.
As shown in Figure 5; It is twocouese that the melten gel fluid flows in the pump housing, and when pump housing piston head upwards moved in pump seat main passage 11, the flow direction of pump housing upper channel 13 fluids was consistent with the moving direction of pump housing piston head; When the fluid of pump housing upper channel 13 is forced out the pump housing; Unidirectionally advance the glue valve and opened by the negative pressure of the up formation of piston head, peripheral melten gel fluid is inhaled into pump seat lower channel 14, and forms certain pressure.
As shown in Figure 6, it is two-way that the melten gel fluid flows in the pump housing, but the flow direction of gum exudation mouth melten gel fluid is consistent all the time; When the piston head of the pump housing moves downwards in pump housing main passage 11; Unidirectionally advance the glue valve and pressed in the pump housing and close, press in the subaisle 12 and open unidirectional plastic emitting valve, the melten gel fluid of former incoming flow full pumping body is through unidirectional plastic emitting valve entering main passage 11; Be discharged from the main passage 11 on the full piston head of the outer also stream of the pump housing then, for the up formation pressure of piston head is prepared.
Air pump pedestal of the present invention is to be formed by import aluminum alloy aluminium precision machining; Its machined has two-way cylinder body chamber; Cooperate the melten gel fluid pressure chamber that forms relative sealing with piston head and one-way valve; The melten gel one-way valve when two-way cylinder body is indoor and clockwise, the time and flow counterclockwise, because of flowing and throttling produces high pressure.There are certain proportionate relationship in the cylinder diameter of this two-way cylinder chamber and the diameter of piston rod, and this proportionate relationship is stable to piston head up-downgoing plastic emitting hydrodynamic pressure.
Of the present invention unidirectional to advance the glue valve be a kind of one-way cock of particular design, and it is assembled by valve body and spring and ripple pearl.When piston head moves upward, in the cylinder negative pressure greater than spring pressure, the unidirectional valve open that advances the glue valve, the melten gel fluid flows into pump chamber.When piston head rose to peak, whole two-way cylinder body chamber had been full of the melten gel fluid.
The one-way cock that unidirectional plastic emitting valve of the present invention also is a kind of particular design when piston head moves upward, forms negative pressure in the cylinder, advance the glue valve and advance glue, and the valve ripple pearl of unidirectional plastic emitting valve moves downward under the action of negative pressure in spring reaches simultaneously, closes the plastic emitting valve.In the pump housing, the melten gel fluid of piston head top is forced out outside the pump housing without the plastic emitting valve under the effect of piston head.
Unidirectional plastic emitting valve of the present invention is two tight assemblies that are associated with unidirectional plastic emitting valve.To advance the glue valve be when opening when unidirectional, and unidirectional plastic emitting valve cuts out.When advancing the glue valve and close, unidirectional plastic emitting valve is opened when unidirectional, they to close with opening be to be associated with the operation up and down of piston head, the time of changing between them is short more, the pressure of melten gel fluid output is just steady more.Supercharging in the air pump body comes to this and forms, and the gas pressure that the periphery is given is big more, and the pressure that the melten gel fluid forms in the cylinder body is also big more.
Motion cylinder block of the present invention is a kind of external pressurization source, after in the pressurized air entering cylinder block, through peripheral control circuit, makes that the piston rod drive piston head in the cylinder block pumps.The piston rod of motion cylinder block inserts in the air pump seat together with piston head, makes melten gel fluid pressurized in the piston pump housing through peripheral cylinder block motion.
In sum; The present invention is owing to adopt special structural design and reciprocating pump pedestal and unidirectional combination of advancing glue valve, unidirectional plastic emitting valve and motion cylinder block; Make the melten gel fluid in reciprocating pump in opposite directions with flow to form constant pressure relatively; Flowing velocity moves fluid uniformly, thus the applying glue jeting effect that can evenly control.
More than disclosedly be merely several specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
