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, and because of worn-out mouthful of described melten gel groove, PUR volatilization, not only wastes glue, and contaminated environment; PUR in melten gel groove, repeatedly experience heat, the process of cooling, carbonization, be regeneration glue forever, reuse, the adhesive property of PUR can decline greatly; 3, when start is used at every turn, ability applying glue after the PUR solidifying all must being melted, 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 comprise a columnar glue chamber vertically arranging, the bottom end seal in described glue chamber, in the chamber in glue chamber, be provided with the piston can slide up and down with depression bar, the bottom in glue chamber is provided with gum outlet, glue chamber is provided with the melten gel heater block for melting the PUR particle of splendid attire in its chamber, and described gum outlet is provided with the glue conveying box of heater block by periphery and the nozzle of less glue binding machine 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, pollute the defect of working environment, owing to establishing melten gel heater block in the middle and lower part of glue tank, adopt local heat, the glue of fusing 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 temperature range, what when glue spraying, use is all the glue of the new fusing in bottom, the interior PUR of glue groove that has overcome prior art repeatedly experiences and heats, cooling, the defect of 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 actual applications, still there are some defects: the one, poor sealing---depression bar driven plunger back and forth movement, must there is gap in long-time wearing and tearing, gap location not only can leak glue, causes waste, and PUR melten gel can react with airborne moisture, and then solidify, the bond quality that directly affects PUR, more serious, also can cause the PUR glue remaining in packing element all to scrap; The 2nd, glue spraying precision is not high---and owing to there is larger resistance between piston and glue cavity wall, let us are difficult to by described depression bar being exerted pressure the more accurately glue spraying amount of Control Nozzle; The 3rd, complex structure---need depression bar and piston, quality of fit requires high, and processing cost 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 piston, greatly reduce cost; There will not be the leakage glue, the gas leakage that cause because of piston wear, avoided the excessive wave of glue, avoided PUR melten gel and airborne moisture to react and directly affected the bond quality of PUR, more avoided 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:
