Detailed description of the invention
Now with detailed description of the invention, the utility model technical scheme required for protection is described in further detail by reference to the accompanying drawings.
As depicted in figs. 1 and 2, the utility model is applied in the engineering plastics comminutor of nine joint barrels, wherein first segment barrel has charging aperture 6, and Section of four barrel has exhaust outlet 7, and Section of seven barrel has vacuum port 8 on being, the length of all barrels is 240mm.
As shown in Figure 3 and Figure 4 transfer block have screw thread and realize the effect of convey materials by the rotating band animal material of screw rod along screw advancement; Gear block is generally formed by stacking by the mesh plate that some shapes are identical as shown in Figure 5 and Figure 6, mesh plate quantity in accompanying drawing is 5, the angle a be staggered to form between adjacent two panels mesh plate is called alternate angle, and the thickness of mesh plate is larger, and the shearing force of the larger gear block of alternate angle will be larger; As shown in Figure 7, be SK type transfer block, the thread groove of SK type transfer block is square, can hold more material compared with common transfer block.
Assembled screw rod can be divided into feeding section 1 successively according to the flow direction of material, melt zone 2, exhaust section 3, dispersion section 4, discharge zone 5.In the present embodiment, feeding section 1 is combined successively by following screwing element: the transfer block of helical pitch 48mm length 48mm, the transfer block of helical pitch 64mm length 64mm, the SK type transfer block of helical pitch 72mm length 72mm, the transfer block of helical pitch 72mm length 72mm, the transfer block of helical pitch 64mm length 64mm, the transfer block of two pieces of helical pitch 48mm length 48mm, the transfer block of helical pitch 32mm length 32mm.The effect of feeding section 1 makes material enter in screw rod smoothly, and adopt for 6 times the screwing element of large pitch that material can be avoided to pile up on the position of charging aperture 6 at charging aperture, SK type transfer block can hold more materials, can avoid material stacking further; Helical pitch trend of tapering off after charging aperture 6 of transfer block can make material obtain enough pressure at section tail to impel material to enter melt zone 2 smoothly.
Melt zone 2 is combined successively by following screwing element: two block length 48mm, alternate angle 45
o, mesh plate quantity is the transfer block of the gear block of 5, helical pitch 32mm length 32mm, length 48mm, alternate angle 45
o, mesh plate quantity is the gear block of 5, length 32mm, alternate angle 60
o, mesh plate quantity is the transfer block of the gear block of 4, helical pitch 32mm length 32mm, length 32mm, alternate angle 60
o, mesh plate quantity is the gear block of 4, length 48mm, alternate angle 90
o, mesh plate quantity is the gear block of 5, the reverse thread transfer block of helical pitch 32mm length 16mm.The effect of melt zone 2 makes material melting mixing in this paragraph, and the alternate angle of the gear block of this section is all 45
oor more its shear stress comparatively strong and the region of engagement be made up of two gear blocks can make material molten mixed effect better compared with traditional decentralized arrangement; Be 90 at the alternate angle of this section of last gear block
o, the resistance that can also increase material flowing except increasing joggled strength increases the pressure of this section, and this section of last reverse thread transfer block plays too and increases flow of material dynamic resistance and increase stressed effect.
Exhaust section 3 is combined successively by following screwing element: the transfer block of two pieces of helical pitch 64mm length 64mm, the transfer block of three pieces of helical pitch 48mm length 48mm, the transfer block of helical pitch 32mm length 32mm.The initial transfer block of exhaust section 3, namely the transfer block of helical pitch 64mm length 64mm is positioned at immediately below exhaust outlet 7.The effect of exhaust outlet 7 has two: first Exhaust Gas release portion pressure, and it two is drop into material from exhaust outlet 7, and the effect of exhaust section 3 is also correspondingly to allow material enter smoothly in screw rod.The transfer block helical pitch of this section tapers off trend, and its effect is similar to feeding section 1, even if material obtains certain pressure at this section of section tail thus makes material enter dispersion section 4 smoothly.
Dispersion section 4 is combined successively by following screwing element: two length 48mm, alternate angles 45
o, mesh plate quantity is the transfer block of the gear block of 5, helical pitch 48mm length 48mm, two length 48mm, alternate angles 45
o, mesh plate quantity is the transfer block of the gear block of 5, helical pitch 48mm length 48mm, length 48mm, alternate angle 45
o, mesh plate quantity is the transfer block of the gear block of 5, helical pitch 32mm length 32mm, length 32mm alternate angle 60
o, mesh plate quantity is the gear block of 4, length 48mm, alternate angle 90
o, mesh plate quantity is the gear block of 5, the reverse thread transfer block of helical pitch 32mm length 16mm.The effect of dispersion section 4 is dispersion of materials, in the present embodiment, the section of dispersion 4 has three region of engagements and an independent engagement block, wherein between second region of engagement and the 3rd region of engagement, be separated with an independently gear block, in existing technology generally this independently gear block be merged in second region of engagement, this problem that the shearing force of this region of engagement excessive attacking material surface can be made simultaneously also to cause temperature too high, now arranges separately this gear block the problem that the shearing force of this region of engagement can be avoided too high.The gear block of the last employing alternate angle 90 at section end and reverse thread transfer block, the resistance that increase material passes through reduces material flow rate makes the dispersion of materials time longer.Because PA6 material can produce more volatile materials when producing, under in the end the reverse thread transfer block of a joint is located at vacuum port, the volatile materials in material can be allowed to be sucked away from vacuum port more up hill and dale.
Discharge zone 5 is combined successively by following screwing element: the transfer block of two helical pitch 64mm length 64mm, the transfer block of helical pitch 48mm length 48mm, the transfer block of five helical pitch 32mm length 32mm.The transfer block helical pitch trend of tapering off of this section can make material have certain pressure in exit.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
