Description
Technical field
The utility model belongs to the leather label machine field, relates in particular to a kind of leather label machine injection valve.
Background technology
China is as the big country of clothes, sport footwear, case and bag production and outlet, and related industries is huge.The soft mark of PVC that adopts in trade mark on clothes, sport footwear, the case and bag, decorations board, the annex is claimed leather mark again, has huge industry size.And leather mark also is widely used in handicrafts such as scape frame, suspension member, plate mat and makes, because it has the characteristic of waterproof, wear-resisting, environmental protection, leisure, just used by growing field with fast speeds.
At present, the instillation in the domestic leather mark production process, baking, refrigerating work procedure all adopt the manual mode of production, and efficient is low, defect rate is high, and need a large amount of skilled workers.Along with the continuous rising of experienced operator's in short supply day by day and labor cost, need a kind of full-automatic leather label machine that can accomplish the whole production procedures of leather mark by machine automatically.
The technological core of full-automatic leather label machine and tackling key problem difficult point are the instillation of mixed solution.The composition of the soft mark mixed solution of PVC is additives such as PVC powder, epoxidized soybean oil, color, ATBC and hard oil, anti-oxidant, anti-wear agent, brightener, is a kind of oil-bound distemper intermixture.Because the soft target unit of PVC dropped amount is very little, minimum is 0.02 gram, and is on the mould of an opening, to instil, thus require that the high velocity jet valve body of full-automatic leather label machine is long-pending little, on-off effect is fast, and close back noresidue drop and fall.Butterfly valve, ball valve and gate valve etc. commonly used at present all can't satisfy above-mentioned requirements simultaneously.
Summary of the invention
Big for the volume of the injection valve that overcomes existing leather label machine, on-off effect is slow, have the deficiency of debris drippage after closing, the utility model provides that a kind of volume is little, the on-off effect rapid speed, close the leather label machine high velocity jet valve that noresidue drop in back fell, guaranteed the leather mark quality.
The utility model solves the technical scheme that its technical problem adopted:
A kind of leather label machine high velocity jet valve comprises valve body and spool, and said spool passes said valve body; Said injection valve also comprises the instillation head; The said head that instils is installed in the bottom of said valve body, and said spool bottom penetrates the inner cavity of said head, and the bottom of the cavity of said instillation head is conical inclined surface; The awl point of said conical inclined surface is communicated with the dropping liquid aperture; The lower end of said spool is provided with the conical plush copper with said conical inclined surface coupling, and the awl point of said conical plush copper is aimed at said dropping liquid aperture, has charging aperture on the said valve body; Said charging aperture is communicated with said cavity, and said spool top is connected with the driving mechanism that moves up and down in order to the control spool.
Among the present invention, when the high velocity jet valve cuts out, the awl of conical plush copper point shutoff dropping liquid aperture; The side of conical plush copper and the conical inclined surface at the bottom of the instillation head cavity fit tightly; Form sealing surface, further guarantee to close fast, do not have raffinate to ooze; Improve the sealing when closing, further guarantee the leather mark product quality.
Further; The middle part of the cavity of the described head that instils is provided with the elliposoidal cavity; The diameter of the bottom of described spool is less than the upper part diameter of spool, and the junction of the upper and lower part of spool is positioned at described elliposoidal cavity, and is gapped between the cavity wall of the bottom of spool and the head that instils.The liquid material can guarantee again that flow was small successfully toward dirty when both having guaranteed that the high velocity jet valve is opened, shutoff dropping liquid aperture immediately when being convenient to close.Make that the switching reaction of high velocity jet valve is quicker.
Further again, have the dropping liquid passage on the said instillation head, the lower end of said dropping liquid passage is communicated with said elliposoidal cavity, and the upper end of said dropping liquid passage is communicated with said charging aperture.
Preferably, said driving mechanism comprises piston, spring, upper locking nut, and said upper locking nut is fixedly connected with said valve body upper end; Be provided with installation cavity between said upper locking nut and the valve body; Be provided with the piston that is fixedly connected with said spool in the said installation cavity, the installation cavity of said piston top is a upper plenum, and the installation cavity of said piston below is following cavity; Said piston outer wall and said valve interior wall are tightly connected; The compression spring is installed in the said upper plenum, and said valve body is provided with the air inlet that is communicated with said cavity down, and said air inlet is connected with high-pressure air source through controlled solenoid valve.
Further; Be equipped with the adjustable limiting thimble on the described upper locking nut; Adjustable limiting thimble and upper locking nut are through being threaded, and the syringe needle of adjustable limiting thimble is positioned at described upper plenum, and the axis of adjustable limiting thimble and the axis of described spool are point-blank.The syringe needle of adjustable limiting thimble on the spool that moves play position-limiting action, spool rises highly, spool bottom and the space of instiling between head are big, the dropping liquid flow is big, spool rises lowly, spool bottom and the space of instiling between head are little, the dropping liquid flow is little.Can adjust the distance that its syringe needle exposes through rotation adjustable limiting thimble, thus the maximum dropping liquid flow of control high velocity jet valve.
The aperture of said dropping liquid aperture is 0.1～2.0mm.When guaranteeing the dropping liquid aperture by shutoff, the noresidue drop falls, and guarantees the leather mark quality.
