The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Embodiment one, and referring to Fig. 1, a kind of Glue dripping head with resorption function comprises Glue dripping head main body 1, driving cylinder 2 and resorption power controlling organization 3.Driving cylinder 2 is positioned at the left side of Glue dripping head main body 1.
The left end of Glue dripping head main body 1 is provided with inlet 11.The right-hand member of Glue dripping head main body 1 is provided with liquid outlet 12.The inside of Glue dripping head main body 1 is provided with the fluid course 13 that is communicated with inlet 11 and liquid outlet 12.Be provided with isometrical section 131 in the fluid course 13.Isometrical section 131 cross section is circular.Be provided with plug 5 in the fluid course 13.Plug 5 is cylindrical.The left end of plug 5 is provided with chamfering 51.Between plug 5 and isometrical section 131 for being sealed and matched.
Piston 22 and piston rod 23 that driving cylinder 2 comprises cylinder body 21, matches with cylinder body 21.Cylinder body 21 is detachably connected with Glue dripping head main body 1.The left end of cylinder body 21 is provided with the first through hole 211.The right-hand member of cylinder body 21 is provided with the second through hole 212.Piston 22 is between the first through hole 211 and the second through hole 212.Piston 22 links together with the left end of piston rod 23.But be located in the Glue dripping head main body 1 to the right-hand member plug of piston rod 23.The right-hand member of piston rod 23 is fixed together with plug 5.Piston rod 23 is sealed connected together with Glue dripping head main body 1 by the first sealing ring 41.Piston rod 23 is sealed connected together with cylinder body 21 by the 3rd sealing ring 43
Resorption power controlling organization 3 comprises along left and right directions and wears push rod 31 and locking nut 32 in the cylinder body 21.The right-hand member of push rod 31 is the polished rod section, and left end is thread segment.Push rod 31 is threaded togather with cylinder body 21.Locking nut 32 is threaded togather with push rod 31.Acting as of locking nut 32 prevents that push rod 31 is loosening.The polished rod section of push rod 31 is sealed connected together with cylinder body 21 by the second password circle 42.
Opening method of the present utility model is: from the first through hole 211 access compressed air or hydraulic oil, piston 22 drives plug 5 by piston rod 23 and moves to right, plug 5 leaves isometrical section 131, this moment, inlet 11 and liquid outlet 12 were in connected state, and the glue that flows into from inlet 11 can flow out from liquid outlet 12.
Referring to Fig. 2, closing method of the present utility model is: from the second through hole 212 access compressed air or hydraulic oil, piston 22 drives plug 5 by piston rod 23 and moves to left, then piston 22 stops to move to left when piston 22 abuts to push rod 31, plug 5 enters isometrical section 131 from isometrical section 131 right-hand member, after plug 5 enters isometrical section 131 isometrical section 131 is blocked, so that inlet 11 and liquid outlet 12 are in off-state, enter the increase of isometrical section 131 distance along with plug 5, the space that fluid course 13 is positioned at the plug right side increases, so that the pressure in this space is lower than outside air pressure, externally under the effect of air pressure, glue in the liquid outlet 12 is drawn back in the liquid outlet 12, does not ooze phenomenon thereby can not produce.Shower nozzle is the normally closed shower nozzle of Self-resetting in the present embodiment.
Flowability such as pectin is higher, then by rotating push rod 31, make push rod 31 enter contraction in length in the cylinder body 21, play the effect that increases piston 22 stroke left, so that in the closed process, the degree of depth that plug 5 insertions are isometrical section 131 is larger, the pressure drop of liquid outlet 12 inside is large, external pressure greatly also is that resorption power is large to the pressure of the glue that is positioned at liquid outlet 12, and glue is not easy to flow out.
When needing to clean the utility model, with Glue dripping head main body 1 with cylinder body 21 separately, and from piston rod 23 extractions, be stained with glue this moment on plug 5 and the piston rod 23 position all exposes outside, can clean plug 5 and piston rod 23 easily.Glue head main body 1 inside also can be cleaned and be dredged easily.
Embodiment two, and referring to Fig. 3, with the difference of embodiment one be: driving cylinder 2 is arranged on the right side of Glue dripping head main body 1, and piston rod 23 is connected to the right-hand member of plug 5 accordingly.Plug 5 is provided with the resilient surface layer that is made by rubber.
Resorption power controlling organization 3 comprises the chute 34 that is arranged on the cylinder body 21, be slidingly connected at the block 35 in the chute 34 and block 35 is fixed on clamping screw 33 on the chute 34.
Adjusting the method that plug 5 enters isometrical section 131 the degree of depth is: unclamp bolt 33,, by bolt 33 block 35 is locked on the chute 34 and gets final product to desired location at chute 34 interior mobile blocks 35.
The method of opening and closing shower nozzle is identical with embodiment one, does not do repeat specification.
