Description
Technical field
The utility model relates to the extrusion equipment of goods such as a kind of production and processing plastics casting films, sheet, specifically a kind of planetary-screw curtain coating extruder of assembling brilliant drying, vacuum dehumidifying, melt extruding disposable solution production and processing crystalline material.
Background technology
In the middle of our daily life, should all to contact and use plastic products every day, such as various packaging material such as food, medicine, hardware ﹠ tools and card matrix material, bank card, identity card, electronic tag or the like.Just at present we are in the middle of these materials that use, in the middle of production and processing, should all to use extruder to plastify and extrude processing, but the different extrusion way of employing is also arranged according to different materials, just present crystalline material of using such as polyester PET etc., the production expressing technique flow process that is adopted is, raw material are earlier with crystallizing and drying dehumidifier desiccant dehumidification, after add extruder again and melt extrude.Because polyester PET is a kind of crystalline material, in the polyester macromolecule chain, contain ester group, because ester group has the hygroscopicity tendency, under the situation of being heated, be to have the moisture existence of trace that hydrolysis also very easily takes place, consequently in the process of processing and forming, can produce a large amount of bubbles, influence ordinary production, make molecular weight and molecular weight, the PET quality variation because of hydrolytic degradation simultaneously, so before single screw rod and twin-screw production and processing melt extruded, material must will carry out crystallizing and drying to be handled.Use The tape casting to process at home and abroad at present, have only two kinds of extruders nothing but, first kind is single screw extrusion machine, and second kind is double screw extruder.
With regard to first kind of single screw extrusion machine, it produces polyester PET material technology flow process is first crystallizing and drying dehumidifying, the back adds single screw extrusion machine and melt extrudes, because its single screw-rod structure design relatively is fairly simple, be nothing but equidistantly not wait deeply or equidistantly do not wait dark change so again and again, design it in any case and can only play a kind of effect that plasticized article is increased extruding force, its result only is to mass transport, extruding, utilize external heat source and push fusion, such result has some disadvantage: 1, use the crystallizing and drying dehumidifier, energy consumption is big, efficient is low, raw material pollute easily through link is many, the crystallizing and drying overlong time needs more than 6 hours.2, since material in the middle of melt extruding, be to utilize outside heat of high temperature extruding fusion, its operating efficiency again can not be too fast, do not fuse phenomenon because of carrying too fast material to absorb less than the abundant heat in outside, do not fuse material just in phenomenons such as the excessive screw rod fractures of thread groove the inside caking blocking current, but production efficiency slows down and be that high temperature is big to the consumption of plastic molecules structure, makes its unstable product quality, occur easily that the color color is inhomogeneous, flavescence, become fragile, phenomenon such as glue stain.3, plurality of raw materials compounding symphysis product is not stirred with joint efforts.4, full reclaimed materials secondary processing product can't meet the quality requirement, and is unfavorable to environmental protection.5, power consumption is big, the each side defective such as yield poorly.Its operation principle is main motor-driven reductor, is extruded by the single screw rod rotation of reductor slow-speed shaft transmission.
Second kind of double screw extruder, its type can be superior more a lot of than single screw rod relatively again, type kind also has several, such as bicone double screw extruder, parallel double-screw extruder or the like, no matter its structure design principle of any double screw extruder has just added a screw rod on single screw rod, work type can aspect added a screw rod extruding force be much bigger really, but this wherein will to reach plasticizing fully complete to the PET plastic products be the problem that can not change its essence by extruding force.
With regard to the structural type energy of above single screw rod and double screw extruder, be to moisture contained in the middle of the graininess polyester PET, it almost is very difficult getting rid of in the middle of extruder production.So the processing process that continues into the present up to present home and abroad is first crystallizing and drying, back fusion extrusion casting casting sheet.Because use the crystallizing and drying dehumidifier that a lot of defectives are also arranged, 1, crystallization time is wanted 2 hours, the desiccant dehumidification time is wanted 4 ~ 5 hours, and this just causes each start to produce the work of will getting ready before in 6 ~ 7 hours.2, energy resource consumption is big: because its raw material all is a graininess, using Electric heating to toast, the moisture in the middle of making slowly evaporates.The powder that produces after 3, crystallization is stirred is big.4, change raw material handling difficulty, about 2 ~ 3 hours of clearance time.5, equipment is installed and is taken up an area of greatly, and many installing engineerings of auxiliary amount is big, regularly replace drier, heater, filter etc.Thus according to existing manufacturing technique flow process elder generation crystallizing and drying, after the method that melt extrudes promptly: energy consumption is big, yield poorly, complex manufacturing, full reclaimed materials secondary production and processing product quality do not reach requirement, are unfavorable for environmental protection etc.
The utility model content
Technical problem to be solved in the utility model provides single-driving type planetary-screw curtain coating extruder at the existing in prior technology defective, the hygroscopicity problem that is had according to the polyester PET material, in the middle of the thermoplasticity plasticizing, do not use under the prerequisite of crystallizing and drying dehumidifier, disposable solution crystallizing and drying dehumidifies, melt extrudes problems such as casting sheet in the middle of planetary-screw curtain coating extruder, this will help saving a large amount of energy, and product quality is more stable.
The technical scheme that its technical problem that solves the utility model adopts is: single-driving type planetary-screw curtain coating extruder, its structure comprise hopper feeding part, host driven transmission deceleration part, feeding regenerator section, planet fluxing zone, single screw rod extruding part, filter, positive battery metering pump, rack-style mould, main frame base support; Described hopper feeding part, feeding regenerator section, planet fluxing zone, single screw rod extruding part, filter, positive battery metering pump, rack-style mould connect successively, and the single screw rod in planet driving screw, planet small screw and the single screw rod extruding part in described host driven transmission deceleration part drive feeding spiro rod and the planet fluxing zone rotates simultaneously; Between described feeding regenerator section and the single screw rod extruding part is the planet fluxing zone, described planet fluxing zone is two sections of AB, structure comprises planet plasticizing barrel A, planet driving screw, planet small screw, planet plasticizing barrel B, after described planet driving screw, planet small screw are nested together wherein planet driving screw one end connect feeding spiro rod on the host driven transmission deceleration part, and the other end connects on single screw rod of single screw rod extruding part, and described planet driving screw, planet small screw arranged outside have planet plasticizing barrel A and planet plasticizing barrel B.
