Description
Technical field
The present invention relates to the PUR packing element melten gel system that less glue binding machine uses.
Background technology
The colloidal sol system that traditional hot melt adhesive binding machine uses, is mainly made up of a melten gel groove, because of described melten gelWorn-out mouthful of groove, PUR volatilization, not only wastes glue, and contaminated environment; PUR in melten gel groove, anti-Multiple experience heats, the process of cooling, carbonization, is regeneration glue forever, reuses PUR bondingPerformance can decline greatly; 3,, when each start is used, the PUR solidifying all just can must be executed after fusingGlue, the melten gel time is long, and glue temperature is wayward.
ZL201220457130.4 discloses a kind of " the glue tank of glue spraying formula less glue binding machine ", mainly comprises that one is perpendicularThe straight columnar glue chamber arranging, the bottom end seal in described glue chamber, is provided with and can slide up and down in the chamber in glue chamberWith the piston of depression bar, the bottom in glue chamber is provided with gum outlet, and glue chamber is provided with for melting splendid attire in its chamberThe melten gel heater block of PUR particle, described gum outlet is provided with glue conveying box and the wireless glue of heater block by peripheryThe nozzle of installation is connected. Adopt technique scheme, replaced the glue groove of prior art with airtight packing element,Under the sealing state of PUR in glue tank, heat, the PUR having overcome in glue groove ceaselessly volatilizees, pollutesThe defect of working environment, owing to establishing melten gel heater block in the middle and lower part of glue tank, adopts local heat, moltenThe glue of changing is pressed into nozzle by the gum outlet of glue pot bottom through glue conveying box under pressure, this structure,Without PURs all in glue tank is all melted, the melten gel time is short, and glue temperature is easily controlled at best temperatureDegree scope, what when glue spraying, use is all the glue of the new fusing in bottom, has overcome the interior hot melt of glue groove of prior artGlue repeatedly experience heat, the defect of cooling, carbonization, the adhesive property of PUR can not reduce. Although this" the glue tank of glue spraying formula less glue binding machine " overcome some technical problems of prior art, but, in realityIn application, still there are some defects: the one, poor sealing---depression bar driven plunger back and forth movement, when longBetween wearing and tearing must there is gap, gap location not only can leak glue, causes waste, and the meeting of PUR melten gel and airIn moisture react, and then solidify, directly affect the bond quality of PUR, more serious, also can makeThe PUR glue that becomes to remain in packing element is all scrapped; The 2nd, glue spraying precision is not high---in piston and glue chamberBetween wall, there is larger resistance, make us be difficult to more accurately control by described depression bar is exerted pressureThe glue spraying amount of nozzle processed; The 3rd, complex structure---need depression bar and piston, quality of fit requires high, processingCost is high.
Summary of the invention
The object of this invention is to provide a kind of PUR packing element melten gel system, simple in structure, need not depression bar and workPlug, greatly reduces cost; There will not be the leakage glue, the gas leakage that cause because of piston wear, avoided outside glueExcessive wave, has avoided PUR melten gel and airborne moisture to react and has directly affected the bond quality of PUR,More avoid causing the PUR glue remaining in glue tank all to scrap; Glue spraying precision improves greatly.
For achieving the above object, the present invention adopts following technical scheme:

On described right clamping plate, be provided with the retainer plate for placing top cover labyrinth.
The external diameter of the internal diameter of described rubber melting cylinder and commercially available PUR pail pack matches, and the height of rubber melting cylinder is greater thanThe height of described commercially available PUR pail pack.
Compared with prior art the invention has the beneficial effects as follows: owing to adopting technique scheme, this rubber melting cylinderTwo ends be up and down respectively equipped with top cover labyrinth and lower sealing cover, in bottom and/or the lower sealing cover inside of rubber melting cylinderBe provided with for melting splendid attire in the melten gel heater block of the PUR of this rubber melting cylinder inner chamber particle, under lower sealing coverPortion is also provided with gum outlet, and described gum outlet is provided with the glue conveying box of heater block and less glue binding machine by peripheryNozzle is connected, and top cover labyrinth is provided with air admission hole, and the inner chamber of this air admission hole one end and described rubber melting cylinder connects,The other end is connected with compressed air source by tracheae, on the tracheae between described air admission hole and compressed air sourceBe provided with the moisture filter device for dry air, this structure, the inner chamber of rubber melting cylinder seals completely, utilizesAir admission hole on top cover labyrinth passes into dry air, exerts pressure to the PUR melten gel in rubber melting cylinder from top to bottom, logicalCross to control and pass into the air pressure of dry air, carry out the glue spraying amount of Control Nozzle, the beneficial effect bringing is exactly---
1. simple in structure. Need not depression bar and piston, greatly reduce cost;
2, there will not be the leakage glue, the gas leakage that cause because of piston wear, avoided the excessive wave of glue, avoidedPUR melten gel and airborne moisture react and directly affect the bond quality of PUR, have more avoided causing surplusRemaining PUR glue in rubber melting cylinder is all scrapped;
3, glue spraying precision improves greatly. In prior art, between piston and rubber melting cylinder inwall, there is larger resistance,And, being greater than the resistance motion is got up from quiet resistance when moving, the resistance after wearing and tearing is less than before wearing and tearingResistance, make be difficult to by exerting pressure the more accurately glue spraying amount of Control Nozzle. The present invention is because cancellingPiston, there is no resistance larger between piston and rubber melting cylinder inwall, control accuracy not only greatly improve, andAnd very stable.
Directly adopt dry compressed air to replace piston, utilized this characteristic of melten gel thickness, what be driedAfter compressed air passes into, melten gel can not be dispelled, initiative solution long-term existence in wireless mucilage binding fieldInterior above-mentioned technical barrier.
