The object of the invention is the shortcoming and defect existed to overcome prior art, and provide a kind of synchronous double-side to apply high-peeling strength TPU Compound Fabric process units, to enhance productivity and peel strength.
For realizing first object of the present invention, technical scheme of the present invention includes symmetrical expression two-layer compound die head and TPU material extrusion mechanism, described symmetrical expression two-layer compound die head includes two points of symmetrical up and down die bodys, composite channel is provided with between each point die body, one end of described composite channel is base cloth charging aperture, the other end is shaping outlet, each point of die body is provided with the feeding-passage be connected with composite channel, described TPU material extrusion mechanism includes two covers, and often cover TPU material extrusion mechanism includes TPU extruder and is connected to the Melt Pump of TPU extruder discharging end, this Melt Pump includes Melt Pump motor, described TPU extruder is provided with for providing the material extrusion motor extruding power and the dog-house dropped into for TPU raw material, the discharge end of the Melt Pump of two described cover TPU material extrusion mechanisms is connected with the feeding-passage of above-mentioned two points of die bodys respectively.
By this setting, adopt extruder material extrusion and by Melt Pump to TPU melt pressurization feed, then two points of die bodys of symmetrical expression two-layer compound die head are passed through to the high pressure coating simultaneously of the both sides up and down of base cloth, compared to traditional casting machine production technology, this arranges production coating efficiency and greatly improves, and the TPU melt of high pressure conditions is molten is better seeped into Ji Bunei, the bond strength of the two improves greatly, and then improves its peel strength.
Further setting is provided with pressure sensor (P3), this pressure sensor (P3) output pressure signal in described TPU extruder discharging end, and by the first PLC module and the first frequency converter, this first transducer drive controls material extrusion motor.
By the pressure sensor (P3) of this setting, this pressure sensor (P3) output pressure signal, and control to drive material extrusion motor, the TPU melt that TPU extruder is extruded can be continually, and the extrusion capacity of TPU melt can obtain Balance route, for follow-up Melt Pump accurately controls to provide prerequisite and guarantee to the pressure of TPU melt, and then facilitate TPU melt and effectively can permeate woven cloth (Ji Bu), ensure the peel strength of coating.
Further setting be described two points of die bodys feeding-passage in be provided with pressure sensor (P1, P2), this pressure sensor (P1, P2) output pressure signal, and feeding back to the second PLC module and the second frequency converter, this second transducer drive controls Melt Pump motor.
By this setting, pressure signal is also fed back to Melt Pump motor by PLC by the pressure sensor (P1, P2) all arranged in the feeding-passage of two points of die bodys, and then make TPU melt pressure ensure enough pressure by Melt Pump, make TPU melt effectively can permeate woven cloth, reach the effect improving peel strength.
Further setting is provided with equidistant etc. the not dark gradual change type screw rod with mixing head in described TPU extruder, screw diameter 90mm-120mm, draw ratio 28:1-32:1, compression ratio 2.5-3.5.
Further setting is the wide cut 1600mm-2300mm of the composite channel of described symmetrical expression two-layer compound die head.
In sum, advantage of the present invention is: production efficiency is high, and can according to coating processes need the material extrusion speed of TPU extruder and the feed pressure of Melt Pump are accurately controlled, ensure that TPU melt effectively can permeate woven cloth, reach the effect improving peel strength.
Below in conjunction with specification drawings and specific embodiments, the present invention is described further.
