The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Like Fig. 1～Fig. 9, Figure 11～shown in Figure 13; Compressing grains machine of the present invention; Comprise that the double-screw type in the head 1 extrudes pay-off and extrude the discharge barrel 2 that pay-off cooperates with this; The exit of discharge barrel 2 is provided with the extrusion die 3 that has discharge opening 30, in the discharge barrel 2, extrudes between pay-off and the extrusion die 3 at twin screw and to be provided with by-passing parts 5; Twin screw extrude be provided with between pay-off and the by-passing parts 5 with by-passing parts 5 each other by touch have a centre bore 40 gather charging tray 4; The supplied materials side of by-passing parts 5 is evenly equipped with splitter box 51, and splitter box 51 converges at the blow tank 53 of by-passing parts exit side, and blow tank 53 is corresponding with the discharge opening 30 of extrusion die 3.The hollow charging tray 4 that gathers of the present invention can be extruded Double Circle stock column that pay-off sees off with twin screw and assembles and change over mono-cylindrical and water conservancy diversion before by-passing parts 5; Supplied materials side at by-passing parts 5 is evenly equipped with splitter box 51 as material channel; Guarantee to assemble the mono-cylindrical material bar that forms and can evenly be branched to extrusion die 3, make material evenly to extrude, thus the granule even particle size that makes; Good looking appearance obviously improves the particle appearance quality.The squeeze pressure of compressing grains machine of the present invention can float in 45000N～150000N scope; When feeding at first; The feeding amount adopts less relatively squeeze pressure 45000N-6000N more at least; Feeding is then adopted relatively large pressure 70000N～120000N extruding after getting into more stable normality, if the feeding amount is big, can also suitably increase squeeze pressure.
Like Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, for further improving granular mass, said splitter box 51 is the sector diffuence groove, is shunting ridge 52 between the adjacent two sector diffuence grooves; Shunting ridge 52 is as separation between the sector diffuence groove and by-passing parts and gather the contacted part of charging tray, plays the effect of transmitting extruding force, and the sector diffuence groove is more shallow near the degree of depth of the part groove at middle part; Area is less, and extruding force is bigger, and corresponding material flow is less; And darker near the degree of depth of the part groove of circumference, area is bigger, and extruding force is less; Help giving full play to the homogenization of by-passing parts, make that the material bar linear velocity of extruding is more consistent, granule is more even.
For taking into account uniformity and easy to process, the number of sector diffuence groove is generally 4-7.
Like Fig. 5 and shown in Figure 6,, avoid template 3 local pressures excessive and damage for extruding force is delivered to extrusion die 3 uniformly; Should be provided with central boss 55 at the center of the exit side of said by-passing parts 5, be provided with back-up block 56 around the exit side, central boss 55 and back-up block 56 respectively with the center of extrusion die 3 with contact all around; Blow tank 53 is between central boss 55 and back-up block 56; Like this, the suffered pressure ratio of template is more even, also makes material to extrude more equably.
Like Fig. 4 and shown in Figure 6, for making things convenient for the location of by-passing parts 5, can be provided with in the supplied materials side of said by-passing parts 5 with centre bore 40 adaptive gather charging tray bayonet socket 54.
Shown in figure 11; Among the present invention; The screw rod 7 that double-screw type is extruded pay-off is provided with cooling structure; Said cooling structure be included in offer on the screw rod 7 with concentric blind hole of screw axis 70 and the inner cool tube 71 that is provided with cooling inlet 74; The cooling lid 72 that inner cool tube 71 passes this blind hole 70 of sealing stretch in the said blind hole 70 and its built-in length less than blind hole 70 degree of depth, cooling cover 72 and is had the cooling cover cavity 720 that is provided with coolant outlet 75, the cooling duct 700 that forms between inner cool tube 71 and the blind pore wall with cool off cover cavity 720 and be communicated with.This structure can feed cooling medium screw rod 7 is cooled off in running; Cooling medium is got into by cooling inlet 74, and the inner cool tube 71 of flowing through is flowed out by coolant outlet 75 with cooling duct 700, cooling cover cavity 720 backs, temperature arrising caused by friction in the time of can avoiding the equipment operation and the material viscosity that causes increases; Be prone to problems such as bonding; Guarantee normal discharging, for mechanical pelletizing provides precondition, the equipment that also makes can be applicable to the material extrusion granulator that viscosity is big.
For same purpose, as shown in Figure 1, can be on the such scheme basis, the barrel of extruding pay-off at double-screw type adds water collar 10 etc., and barrel is also lowered the temperature, and reaches better effect.
Shown in figure 11; Said inner cool tube 71 can be fixed on cooling through nut 73 and cover on 72, and said cooling lid 72 is fixedly connected with head 1, nut 73 and cooling off cover 72 can the while as the axial limiting structure of screw rod 7; Be limited to the axial displacement of extruding force screw rod 7 when excessive; Avoid two screw rods 7 to hang each other, improve the equipment reliability of operation, the equipment that also makes can be applicable to the material extrusion granulator that viscosity is big.
Be same purpose, on the such scheme basis, also can increase front end fixed disk 76 at the bearing side of screw rod 7, front end fixed disk 76 is fixedly connected with barrel, guarantees that screw rod 7 do not hang each other.
Like Fig. 8 and shown in Figure 9; For improving granular mass, said extrusion die 3 does not adopt common cylindrical hole, but at the supplied materials sidetracking macropore 31 of said extrusion die 3; The discharging sidetracking aperture 32 of extrusion die; Macropore 31 correspondences are communicated with one or two apertures 32 and form discharge opening 30, and material by further compression, obtains granule more closely through extrusion die 3 time like this.Consider the discharging uniformity; The aperture 32 of the exit side of extrusion die generally should be uniformly distributed with; Can be communicated with two apertures 32 with a macropore 31 more ground correspondences in the periphery of extrusion die 3, extrusion die 3 is communicated with an aperture 32 near the position at center with a macropore 31 more ground correspondences.
Usually, can bear bigger extruding force, guarantee that equipment also can normally move when the very big material of extruding viscosity for guaranteeing template; Give full play to the squeezing action in discharging hole 30 simultaneously; Said extrusion die 3 should have suitable thickness, and its thickness should reach more than the 30mm usually, considers the processing in hole; Thickness also should not be too thick, and its thickness generally is not more than 40mm.
Like Fig. 1, Figure 12 and shown in Figure 13; Since adopted extruding granulation mode, tightr from the material bar quality that extrusion die comes out, the rotary-cut cutter 6 cutting granulating that the exit side of available extrusion die 3 is provided with; Injure extrusion die 3 when avoiding rotary-cut cutter 6 operation and produce metal fillings; Its cutter hub is the elastic 60 that is convexly curved near the part on sword limit 61, then when feed is adjusted, make 61 two ends, sword limit can both with extrusion die 3 cutting of fitting well.
As shown in Figure 3, for increasing extrusion pressure, said combination bore of gathering the centre bore 40 of charging tray 4 for taper hole and circular hole; Usually; Taper hole at feed end and circular hole at discharge end, promptly also material is pushed gathering charging tray 4 places, the equipment that makes can be applicable to the material extrusion granulator that viscosity is bigger.
