Fig. 2 represents the press-in screw device 12 of this embodiment.2 press-in screw rods 12b, 12c are arranged on the central authorities of orientation by this press-in screw device 12, then configure each press-in screw rod 12a, a 12d respectively in their outside.
Fig. 3 is the section plan of 4 press-in screw rods 12a, 12b, 12c, 12d viewed from the B-B line of Fig. 2 shown in Fig. 2, illustrates the rotary orientation of screw rod blade 14a, 14b, 14c, 14d and the direction of rotation of rotating driveshaft 13 respectively with arrow.The rotation direction of each press-in screw rod 12a, 12b, 12c, 12d above-mentioned spiral in adjacent extruding screw is contrary, all rotates along being positioned in the direction that namely raw material 9 on screw rod blade 14a, 14b, 14c, 14d transport from these ends below vertical.Such as, Fig. 22, central authorities be positioned at left side press-in screw rod 12b as shown in Figure 3 viewed from the top of rotating driveshaft 13 spiral helicine screw rod blade 14b spiral along the left hand direction of drawing.Further, by making press-in screw rod 12b rotate along the clockwise direction (arrow rb direction) of drawing equally seen from above, raw material 9 moves to below along screw rod blade 14b, and then raw material 9 is extruded to shaping roller 4 by the lower surface 21 of screw rod blade 14b.Namely, as shown in Figure 3, viewed from upside, have left-handed spiral-shaped press-in screw rod 14b, the 14d of drawing along seeing that arrow rb, rd direction along drawing dextrorotation (clockwise) rotates from above, spiral-shaped press-in screw rod 14a, the 14c with drawing dextrorotation rotate along arrow ra, rc direction of left-handed (counterclockwise).
In each press-in screw rod 12a ~ 12d, be arranged on 2 of the middle position (middle position of the axis direction of shaping roller 4) of orientation press-in screw rod 12b, 12c(central screw) each rotating driveshaft 13 around, be provided with screw rod blade 14b, 14c of from upper lateral lower end side, angle of inclination being changed smaller respectively.Screw rod blade 14b, 14c of press-in screw rod 12b, 12c of central authorities have pitch interval identical mutually and spiral in opposite direction spiral-shaped, rotate to inward turning (mutual phase despining) mutually when seeing from the supply port 16 of bailing bucket 8.That is, as shown in Figure 3, supply raw materials on the upside of drawing 9 time, from raw material supplying side, mutually along rotating towards the direction that the press-in screw rod of the other side is close, raw material 9 efficiency is entered between screw rod blade 14b, 14c well.Be more specifically that, when overlooking the part between each rotating driveshaft 13 that screw rod 12b, 12c have as shown in FIG. 3, the direction of rotation of each screw rod blade 14b, 14c is consistent with the direction of the supply of raw material 9.Therefore, from the raw material 9 that the upper side from bailing bucket 8 supplies, the entrance between screw rod blade 14b, 14c of central authorities is wide, along with gradually near the gap between these screw rod blades 14b, 14c, and opening narrows.And, while guide raw material 9 limit feeding towards the direction that this opening narrows make screw rod blade 14b, 14c rotate to the inside mutually.Therefore, it is possible to efficiency makes raw material 9 enter between screw rod blade 14b, 14c well.
And screw rod blade 14b, 14c angle of inclination from the upper end of rotating driveshaft 13 to lower end side separately of press-in screw rod 12b, 12c of central authorities diminishes.That is, screw rod blade 14b, 14c respectively in the periphery of rotating driveshaft 13 with each one circle amount be formed successively: vertical profile apparent time there is large angle of inclination (the 1st angle of inclination) and to below (below the vertical) transferring raw material 9 of bailing bucket 8 conveyance blade 22(the 1st transport blade); Vertical profile apparent time has the medium dip angle (2nd angle of inclination) milder than large angle of inclination and compresses blade by being included in the compression blade 23(the 1st removed from the gas the raw material 9 that moves of conveyance blade 22); Vertical profile apparent time has the little angle of inclination (3rd angle of inclination) milder than above-mentioned medium dip angle and pays press-in blade 24(the 1st press-in blade raw material 9 sent here from compression blade 23 being pressed into the power of shaping roller 4).
The tilt angle theta 1 of press-in blade 24 preferably more than 10 °, less than 15 °; Compress more than 1.5 times, less than 2.5 times of the preferred tilt angle theta 1 at press-in blade 24 of tilt angle theta 2 of blade 23; The tilt angle theta 3 of conveyance blade 22 is preferably greater than 2.5 times, less than 3.5 times of tilt angle theta 1 of press-in blade 24.In addition, tilt angle theta 1 ~ θ 3 is the angle of inclination relative to the face orthogonal with rotating driveshaft 13.
Because press-in screw rod 12b, 12c of central authorities rotate along the direction transporting raw material 9 downwards as mentioned above, first the raw material 9 therefore provided to bailing bucket 8 by supply port 16 is carried to the lower side of bailing bucket 8 by conveyance blade 22 by the rotation of press-in screw rod 12b, 12c of central authorities.Then, the compacted blade 23 of raw material 9 after conveyance blade 22 removes the space in raw material, and the lower surface 21 being then pressed into blade 24 is pressed into gap 5(Fig. 1 of shaping roller 4).Now, because the position of the vertical lower end of each screw rod blade 14a ~ 14d is identical mutually, and be rightabout between the spiral helicine rotation direction of these screw rod blades 14a ~ 14d is adjacent each other, therefore can not produce the delay of raw material 9, and raw material 9 can be extruded along the orientation of each press-in screw rod 12a ~ 12d with equally distributed power.
And, while conveyance raw material 9 with to have respectively intrinsic angle of inclination conveyance blade 22, compress blade 23 and press-in blade 24 and carry out the stable supplying of raw material 9, exhaust and pressurization respectively.And owing to transporting with more improving the compression degree of raw material 9 more downwards, therefore raw material 9 is not easy to be attached between screw rod blade 14b, 14c, and raw material 9 is stably clamp-oned the gap 5 of shaping roller 4.
Press-in screw rod 12a, 12d(outside press-in screw rod 12b, the 12c two being arranged on central authorities to be respectively pressed in screw rod 12a ~ 12d 2 of two ends in orientation i.e. outside screw rod) there is spiral helicine screw rod blade 14a, 14d respectively that to be pressed into screw rod 12b, 12c with adjacent central authorities and to spiral in the opposite direction mutually.
Press-in screw rod 12a, 12d outside two do not possess the compression blade 23 that central authorities press-in screw rod 12b, 12c between them have, and only arrange conveyance blade 22 and press-in blade 24 from the upper end of rotating driveshaft 13 to side, lower end.That is, be pressed into each screw rod blade 14a, 14d that screw rod 12a, 12d have separately to possess downwards from the top of vertical: there is the angle of inclination (4th angle of inclination) identical with above-mentioned large angle of inclination and the conveyance blade 22(the 2nd transporting raw material 9 towards the below of vertical transports blade); There is angle of inclination (than above-mentioned 4th angle of inclination mild 5th angle of inclination), the downwards force feed identical with above-mentioned little angle of inclination and be pressed into blade from the press-in blade 24(the 2nd transporting the raw material 9 that blade 22 directly transports).
Further, be located opposite from the lower end of the conveyance blade 22 of epimere side, from be positioned at its hypomere side press-in blade 24 upper end towards the direction of rotation of rotating driveshaft 13 stagger 90 °-1/4 week be configured in top namely around rotating driveshaft 13.Like this, by omitting the compression blade 23 of press-in screw rod 12a, 12d in outside, these press-in screw rods 12a, 12d towards, near the sidewall 31 of housing 11, raw material 9 can not be congestion.As a result, due to the resistance that raw material 9 limit is subject to when sliding edge declines on sidewall 31 can be reduced, therefore, it is possible to suppress the overload of press-in screw rod 12a, the 12d in outside.And, height and position due to the conveyance blade 22 by making press-in screw rod 12b, 12c of the height and position of the conveyance blade 22 of press-in screw rod 12a, the 12d in outside and central authorities staggers and (is more specifically, the upper end level position of the conveyance blade 22 of press-in screw rod 12a, the 12d in outside is lower than the upper end level position of the conveyance blade 22 of press-in screw rod 12b, 12c of central authorities), raw material 9 can be suppressed to be attached on the sidewall 31 of housing 11, and therefore raw material 9 easily successfully transports downwards.
Press-in screw rod 12b, 12c of central authorities adopt all in roughly the same short transverse position with the lower end of each press-in blade 24 of press-in screw rod 12a, the 12d in outside, are pushed by raw material 9 equably by the lower surface 21 of each press-in blade 24 to shaping roller 4.
According to the press-in screw device 12 of the structure illustrated above, raw material 9 can be prevented to be attached to screw rod blade 14(14a ~ 14d) or on being positioned at inside housing 11 sidewall 31, stably can carry out the supply of the raw material 9 to shaping roller 4, and can equably raw material 9 be pushed to shaping roller 4 side.
In addition, the radical of press-in screw rod 12a ~ 12d is not limited in 4, but pushes raw material 9 with being evenly distributed, preferably even number root in order to the axis direction along shaping roller 4.When 2, press-in screw rod 12b, 12c that in above-mentioned embodiment 2 are central also can be only set.
