Technical field
The present invention relates to the production apparatus field of PUR, particularly a kind of PUR discharging device.
Background technology
At present, plastic emitting mechanism used in PUR production system mainly there is also following deficiency: when stopping or suspending plastic emitting, glue discharging mouth also has the slowly outflow of remaining, the phenomenon that kiss-coating silk or glue drip easily occurs, and these collodion silks or glue drip owing to away from plastic emitting mechanism, the heat preservation mechanism in plastic emitting mechanism is difficult to effect and obtains, thus is easily set on glue discharging mouth, glue discharging mouth is caused to block, it is difficult to cleaning.When production system is again started up, needs manually first to clear up, and cleared up the most difficult and time consuming, thus greatly have impact on the production efficiency of enterprise.Further, the glue that cleaned out is broken can only melt down again, could recycle, there is bigger energy waste.
Summary of the invention
It is an object of the invention to provide a kind of automaticity high; cull on glue discharging mouth can be absorbed in glue discharging mouth by shutdown; flow out without cull; without dripping glue; glue discharging mouth is not easily blocked, it is not necessary to cleaning glue discharging mouth, and production efficiency is high; simple in construction, the high ultra-large aperture of reliability is without wire drawing PUR spray gun discharging device.
The technical scheme is that and be achieved in that: a kind of ultra-large aperture is without wire drawing PUR spray gun discharging device, its feature is to include plastic emitting device, plastic emitting switchs, piston, stop and air driven pump, wherein make switch chamber respectively on plastic emitting device, enter glue port, taper plastic emitting port, hollow chamber made by described plastic emitting switch, taper sealing end has also been made in the lower end of plastic emitting switch, described plastic emitting switch sleeve is loaded in switch chamber, described taper sealing end is nested with taper plastic emitting port, it is additionally provided with absorption mesh in the bottom surface of this taper sealing end, and be also formed with hiding glue region between the port of the bottom surface of taper sealing end and taper plastic emitting port；Described piston bush is loaded in the hollow chamber of plastic emitting switch, and described stop is fixedly installed in out the hollow chamber upper end of chamber switch, and the top of described stop is connected with air driven pump；Further respectively have on described plastic emitting switch connect gas port with under connect gas port, this connects gas port with under connect gas port and be respectively communicated in hollow chamber, make upper and lower elevating movement realizing pneumatic control piston.
Further, described piston is made up of piston main body, upper piston ring and lower piston ring, further respectively has setting-in annular groove in the top and bottom of piston main body, and described upper piston ring and lower piston ring are set with on the setting-in annular groove of the top and bottom of piston main body.
Further, described stop is made up of fixed part and annularly-distributed many limited posts on surrounding, fixed part bottom surface, fixed part surrounding lateral surface is additionally provided with external screw thread, the upper end cavity wall of described hollow chamber is corresponding has made internal thread, and this stop is fixedly installed in by the external screw thread on fixed part and the internal thread phase spinning in hollow chamber during plastic emitting switchs；It is additionally provided with connecting screw hole, together with the piston rod that this stop is provided with air driven pump by connecting screw hole thereon is connected at the top of fixed part.
Yet further, the cavity wall of described plastic emitting switch further respectively has long duct and short-bore road, the arrival end in the longest duct with under connect gas port and be connected, the port of export in this long duct is arranged on the internal chamber wall of taper plastic emitting port and hollow chamber junction；The arrival end in described short-bore road with on connect gas port and be connected, the port of export in this short-bore road is arranged on the internal chamber wall of hollow chamber.
The beneficial effect that the present invention obtains: during application, this device is installed in PUR production system, when plastic emitting to be opened, air driven pump effect, plastic emitting switch is lifted up, the taper plastic emitting port of plastic emitting device is opened, and makes to be connected together into glue port, switch chamber, taper plastic emitting port, and PUR flows out from taper plastic emitting port.Owing to taper plastic emitting port have employed ultra-large aperture design, not only plastic emitting efficiency is high, and the phenomenon without wire drawing occurs, plastic emitting quality is at a relatively high.When plastic emitting to be suspended, under air driven pump effect, being pushed down on down by plastic emitting switch, the taper sealing end making plastic emitting switch is embedded in the inner chamber of taper plastic emitting port, taper plastic emitting port is blocked, thus cuts off into glue port, switch connection between chamber, taper plastic emitting port three.Plastic emitting switch push down on lower after, connect down gas port and be injected into compressed air, piston upwards, negative pressure is formed in the bottom of piston, the cull being in taper plastic emitting port is attracted in the glue region, Tibetan adsorbed between mesh of taper plastic emitting port and taper sealing end, will not drip downwards, thus also will not form kiss-coating silk or phenomenon that kiss-coating drips.Now, owing to cull is attracted between taper plastic emitting port and the absorption mesh of taper sealing end, within the scope of the heat preservation mechanism insulation making cull be on this device covers so that this cull will not occur the problem of cooling solidification, thus also would not produce the problem blocking plastic emitting port.When plastic emitting to be again started up, under connect gas port release, above connect gas port and be injected simultaneously into compressed air, piston moves downward, and absorption is released downwards at the cull hidden in glue region, and meanwhile, air driven pump drives plastic emitting switch to be lifted up, normal plastic emitting.Automaticity of the present invention is high, it is not necessary to artificial boundary enters, and flows out without cull, without dripping glue, glue discharging mouth is not easily blocked, it is not necessary to cleaning glue discharging mouth, production efficiency is high, and the structure of each component parts is the most relatively simple, thus also has simple in construction, reliability height, the feature of length in service life.
