Detailed description of the invention

As it is shown in figure 1, be that the one that a preferred embodiment of the present invention is provided is the closeest, kneading blending and modifying preparation dress The overall structure schematic diagram put, mainly includes the double screw extruder 2 driven through change speed gear box by mair motor, squeezes to described twin screw Go out the feeding machine 1 of machine 2 feeding, the discharging of described double screw extruder 2 carried out the Melt Pump 320 of pressurization propelling and to Melt Pump Discharging carries out pelletizing the cooler 3 cooled down.Described feeding machine 1 by low speed pump pressure in the way of to the twin-screw extrusion run up Machine 2 provide room temperature, without layering, in the range of 3 cubic centimetres of unit volumes composition up to standard, to have 0-5 MPa controlled Mixed material, the double screw extruder 2 of run up (700-1100 rev/min) acts on jointly with temperature control device 27, to mixed Compound material carries out being blended, devolatilization, filtration, Melt Pump high pressure are forced to advance, and the melt obtained is further intelligence in described cooler 3 Energy cooling, pelletizing, vertically upward entrance flow downward out without pipeline matrix air-cooled pellet heat sink rear screw, complete processed Journey.

As in figure 2 it is shown, described feeding machine 1 is reverse blocking type pumps feeding machine, it has the hopper 110 of a taper, A downward helical axle 111, the upper end of described downward helical axle 111 and electric rotating machine it is disposed with on the central axis of hopper 110 112 power connect, and described electric rotating machine 112 is fixed on the top of described hopper 110 by support 113；In described hopper 110 There also is provided two and be parallel to the upstream screw axles 114 that hopper 110 sidewall is arranged, two described upstream screw axles 114 also with institute State electric rotating machine 112 power to connect；In the present embodiment, described electric rotating machine 112 first passes through two pairs of first order bevel gears 116 and drives Dynamic two trunnion axis 117 rotate, and described two trunnion axis 117 respectively drive described two by a pair second level bevel gear 118 Upstream screw axle 114 synchronous axial system.

When described electric rotating machine 112 starts, as it is shown on figure 3, the material bottom hopper 110 will be by two upstream screw axles 114 drive the sidewall along hopper 110 upwards to spring up, and then under the drive of described downward helical axle 111, are pressed onto described hopper By the position at center bottom 110, through the synergism of upstream screw axle 114 with downward helical axle 111, material is made to be sufficiently stirred for For homogeneous substance.

It is additionally provided with forced feed gear pump 120, for mixing through abundant bottom hopper 110 bottom described hopper 110 The material closed pump away toward tapping channel 121 direction below hopper 110, in the present embodiment, described tapping channel 121 and Double screw extruder 2 connects, and affects pan feeding speed to prevent the material entering double screw extruder 2 from reversely overflowing, described The outlet section of tapping channel 121 has the reverse mask segments 1211 (as shown in Figure 3) that internal diameter gradually expands.

Wherein, described forced feed gear pump 120 includes a pair intermeshing self-cleaning gear 130, and one of them is self-cleaning Gear 130 is driven by a feeding motor (omission view) and rotates, and is driving gear, and another is driven gear, and two self-cleaning Gear 130 designs in specular.As shown in Figure 4, it is the flank profil enlarged diagram of described self-cleaning gear 130, each from cleaning the teeth Wheel 130 has tooth top and the teeth groove that interval connects, and first crushes the edge of a knife 1321 and second being respectively arranged at two ends with of described tooth top The broken edge of a knife 1322, is provided with the 3rd at the middle part of described teeth groove and crushes the edge of a knife 1323, is provided with the 4th at the middle part of described tooth top and breaks The broken edge of a knife 1324；Described 3rd crushes the edge of a knife 1323 and second crushes part teeth groove is indent first between the edge of a knife 1322 certainly Face cleaning 1331, the described 3rd crush that the edge of a knife 1323 and first crushes between the edge of a knife 1321 part teeth groove is indent second self-cleaning Face 1332, described first crushes the edge of a knife and the 4th crushes the part tooth top is indent the 3rd between the edge of a knife 1324 from face cleaning 1333, described second crushes the edge of a knife 1322 and the 4th four selfs face cleaning that part tooth top is indent crushing between the edge of a knife 1324 1334。

At described self-cleaning gear 130 rotary course, the first of driving gear crush the edge of a knife, second crush the edge of a knife 1322, Three crush the edge of a knife, the 4th crush the edge of a knife 1324 can respectively with first on driven gear from face cleaning 1331, second from face cleaning 1332, the 3rd from face cleaning 1333, the corresponding engagement of four selfs face cleaning 1334；Meanwhile, first on described driven gear crushes The edge of a knife, second crush the edge of a knife the 1322, the 3rd crush the edge of a knife, the 4th crush the edge of a knife 1324 again can respectively with on described driving gear First from face cleaning 1331, second from face cleaning the 1332, the 3rd from face cleaning 1333, the corresponding engagement of four selfs face cleaning 1334.By nibbling During conjunction, the edge of a knife is to scraping effect from the shovel of face cleaning accordingly, it is possible to prevent the card that the materials from bonding of thickness is caused in flank profil Stagnant, blocking and the problem such as efficiency of transmission reduction.

As it is shown in figure 5, be the double spiral shells in the closeest, the kneading blending and modifying preparation facilities that provides of present pre-ferred embodiments The screw-rod structure schematic diagram of bar extruder 2, two screw rod synchronous axial system in the same direction, (do not give figure with the barrel of double screw extruder 2 Show) and barrel on temperature control device 27 synergism, pan feeding is processed into satisfactory discharging.As it can be seen, described material Cylinder is included the superfinishing section of mixing chamber 21, activation section chamber 22, devolatilization section chamber 23, a strengthening segment successively by feeding end to discharge end Chamber 24, secondary devolatilization section chamber 25 and transportation section chamber 26, wherein:
