To being on the contrary, so in the course of the work, driving screw 12 direction of motion is relative with the direction of motion of feed-screw 34, and
And screw rod is synchronously incorgruous that sizing material feeding ability can be made to greatly reinforce, such sizing material can act in the spiral thrust of feed roller 34
Automatically travel forward down, feed roller 34 is driven using single motor 41 alone, together complete feeding with driving screw 12, and using subtracting
Fast case 40 is slowed down；The feeding device 16 of this board mainly utilizes a worm reduction box 40, model CW type, this TV station
Reduction box floor space is little, and cost is relatively low, is suitable for feeding device, due to feed roller 34 stress less, so motor
Power selection, without too big, is preferably chosen 3kw power model, due to the axis of feeding roller 34 and the axis of driving screw 12
For 30 °, enough installing spaces can be provided for worm reduction box 40, can guarantee that the spiral thrust of feed roller 34 is being led again
The component of screw rod 12 axis direction is as big as possible, substantially increases the feeding ability of extruder, improves the board ability of board,
Thus being favorably improved the quality of extruded product, improve production efficiency, improve enterprise's competitiveness in the market.
For solving the problems, such as the overflow of extruder vent, to possibly exhaust ports design exist problem, to air vent
Structure is improved, and the size of designed air vent should be more wider than the width of stream, thereby may be ensured that extruder
The melt sizing material that air vent is not flowed is blocked, simultaneously, the width of extruder steam vent also not should too big it is therefore an objective to
In order to shorten the probability of the sizing material time of staying and sizing material expansion；When sizing material flows through the exhaust section of extruder, due to aerofluxuss segment body
Amassing increases suddenly, and pressure reduces, and causes the air molecule in flowing sizing material, hydrone and lower-molecular substance to escape, from aerofluxuss
Taken away by vacuum pump in hole；As shown in figure 3, vacuum extractor includes anti-overflow exhaust apparatus 26, in order to prevent sizing material from aerofluxuss
Emerge in hole, on steam vent, added with a shaftless screw device 29, the driving means of this exhaust apparatus can directly adopt part
One little torque motor 27, not be used in configuration reduction box, and the side of the direction of rotation in described screw rod for the exhaust apparatus 26, so that
Sizing material dumping is easy；The free end of shaftless screw 29 is connected with motor 27 by shaft coupling 28, and the vacuum pump 43 with motor leads to
Cross pump-line to be connected with the glue case 33 of depositing in anti-overflow exhaust apparatus 26, during operation, motor 27 drives shaftless screw 29, shaftless
Screw 29 rotates formed spiral thrust and stops sizing material melt overflow, because shaftless screw device 29 and sizing material contact surface
Long-pending less, it is possible to larger resistance is formed to lower section sizing material, even if having sizing material to emerge it is also possible in material storing box 33 from the side
The sizing material emerged is taken out；Meanwhile, vacuum pump 43 runs, and gas passes through exhaustor 32 row from shaftless screw 29 intermediate hollow section
Gas, vacuum extractor realizes the aerofluxuss of sizing material and anti-overflow function simultaneously；It should be noted that deposit glue case 33 in Fig. 3 should adopt
Drawer-type structure in prior art, to remove the sizing material emerged in time.
