Description
Technical field
The utility model belongs to polymeric material manufacture field, is specifically related to a kind of device for preparing polymer, especially a kind of polymer extruder head.
Background technology
Macromolecular material is the up-and-coming youngster in Material Field, it mainly comprises synthetic resin and plastics, synthetic fibers and synthetic rubber three major types, usually be referred to as " three large synthetic materials ", compared with other material, plastics have lightweight, corrosion-resistant, specific strength is high, excellent electrical property, be easily processed into various beauty and the features such as bright goods, become the indispensable important composition of material industry, and be the most active field of new and high technology in material industry.
At present, the application of plastics just progressively expands, relate to various aspects and even the daily life of national economy, as replaced the metal materials, timber, pottery, glass, leather, paper, lacquerware, rubber, building stones etc. such as iron and steel, copper, aluminium with plastics.In addition, plastics can also make functional plastic products.Plastic product be widely used in agricultural, fish animal husbandry, electrically, the industrial department such as machinery instrument, automobile, Aero-Space, chemical industry, construction material, packaging.
Plastics have to pass through molding process from moulding material to the conversion of plastic products with practical value, and the method for processing forming of plastic products is extruded, inject, calendering etc., but wherein most important be also the most basic method be extrusion molding.Major part thermoplastic can be processed by the method, the features such as it has continuous seepage, and production efficiency is high, applied range.Can produce tubing, bar, sheet material, film, monofilament, electric wire, profile shapes and hollow container etc., and extrusion molding product is widely used in all trades and professions, is closely related with daily life.
In the Plastics Processing Industry that China is related to this, almost the plastic products of 1/3-1/2 have been come by extrusion molding.As the second largest series products of molding machine, the output of extrusion molding unit and sales volume account for 20% ~ 25% of plastics machinery, and product slates is in industries such as machinery, light industry, chemical industry, boats and ships.
All the time, people are always around how to improve quality of item, save energy and reduce the cost and improve the aspects such as machine performance and improve extruder gradually, namely from the single screw extrusion machine of routine, to new type single screw extruder, double screw extruder, until have the appearance of the Vibration Extrusion machine of great innovative significance 20 end of the centurys.
But at present, the capital equipment being applied to the Polymer moulding such as plastics, rubber field remains takes product as the leading factor with the screw extruder of all sizes such as equidirectional parallel double-screw extruder, anisotropic parallel and conical double screw extruder, and it is closely connected with outlet of extruder by screw.But because polymer malt viscosity is large, make to produce larger resistance during melt flows, this just requires that the pressure needed for melt extrusion strengthens.In order to overcome this defect, can development of new screw extruder being passed through, as increased extruder screw diameter and draw ratio, and improve the methods such as screw speed, but the improvement potentiality of this respect be close to its limit.
In view of the foregoing, need to provide one to reduce melt viscosity, thus reduce the pressure needed for melt extrusion, improve stability of foundation again, device for preparing polymer rational in infrastructure, to overcome the shortcoming in above-mentioned prior-art devices simultaneously.
Utility model content
The utility model provides a kind of polymer extruder head, be included in the first battery lead plate and the second battery lead plate that arrange around melt flow channel, and described polymer extruder head is also included in the ultrasonic transducer arranged above melt flow channel, described melt flow channel and with the junction of titanium alloy ultrasonic transformer around be equipped with heat insulation block.
Preferably, the bottom of described ultrasonic transducer is connected with titanium alloy ultrasonic transformer.
Preferably, ultrasonic probe positioner is provided with in the junction of described ultrasonic transducer and titanium alloy ultrasonic transformer.
According to the polymer extruder head that the utility model provides, around melt flow channel, be provided with two electrode plate, with the orientation of directs polymer molecular melt segment and strand, thus reduce the pressure needed for melt extrusion.Also above melt flow channel, be provided with ultrasonic transducer simultaneously, action intensity can be significantly improved when polymer melt is extruded, the titanium alloy ultrasonic transformer configured bottom ultrasonic transducer directly contacts polymer melt, makes ultrasonic more remarkable to the effect of increasing flow properties of polymer melts.So, while polymer melt is subject to electric field action, also can coordinates and add ultrasonic increasing fluidity of molten, thus greatly facilitate the flowing of melt.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the polymer extruder head structural representation that the utility model preferred embodiment provides.
Detailed description of the invention
Hereinafter also describe the utility model in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Fig. 1 is the polymer extruder head structural representation that the utility model preferred embodiment provides.As shown in Figure 1, the polymer extruder head that the present embodiment provides is included in the first battery lead plate 6 and the second battery lead plate 7 that melt flow channel 4 surrounding is arranged, and described polymer extruder head is also included in the ultrasonic transducer 1 arranged above melt flow channel 4.In this, the bottom of described ultrasonic transducer 1 is connected with titanium alloy ultrasonic transformer 3.
The polymer extruder head that the present embodiment provides provides electric field and ultrasound functions two kinds of polymer-extruded modes.Wherein: while the Electric field extrusion way being provided with battery lead plate can reduce melt viscosity, molecular melt chain marshalling is kept; The Vibration Extrusion mode being provided with ultrasonic transducer is more suitable for blend polymer, is conducive to the mechanical property improving blend polymer.In actual applications, alternately even simultaneously using of two kinds of extrusion ways can be carried out according to actual conditions, thus while guarantee processing effect, also can reduce energy consumption to greatest extent.
In this, after described ultrasonic transducer 1 switches on power, the titanium alloy ultrasonic transformer 3 bottom it is driven to rotate, directly by ultrasonic conducting in the polymer melt of melt flow channel, neither affect the flow stability of polymer melt, also increase melt flow rate, so that polymer-extruded shaping.
In the present embodiment, be provided with ultrasonic probe positioner 2 at ultrasonic transducer 1 and the junction of titanium alloy ultrasonic transformer 3.Described ultrasonic probe positioner, for keeping the stability of titanium alloy ultrasonic transformer, improves product approval effect.
In addition, described melt flow channel 4 and with the junction of titanium alloy ultrasonic transformer 3 around be equipped with heat insulation block 5.In the present embodiment, described heat insulation block all adopts resistant to elevated temperatures ceramic material manufacture, in other embodiment, can adopt other material as required, but is not construed as limiting this utility model.
