Other press-roller device disclosed in new embodiment, because the rotation of the direction of rotation and the screw thread of driving screw 12 of the charging screw thread of propellers 34
It is on the contrary, so in the course of the work, the direction of motion of the direction of motion of driving screw 12 and feed-screw 34 is relative to turn direction
, and screw rod is synchronously incorgruous can greatly reinforce sizing material feeding ability, and such sizing material can be pushed away in the spiral of feed roller 34
Travelled forward automatically under power effect, feed roller 34 is driven alone using single motor I 41, and feeding is together completed with driving screw 12,
And slowed down using reduction box 40；The feeding device 16 of this board mainly utilizes a worm reduction box I 40, model
It is CW types, this TV station reduction box floor space is small, and cost is relatively low, is suitable for feeding device, due to the stress of feed roller 34 less, institute
With motor power selection without too big, 3kw power models are preferably chosen, due to axis and the main spiral shell of feeding roller 34
The axis of bar 12 is 30 °, can provide enough installing spaces for worm reduction box I 40, and feed roller 34 is can guarantee that again
Spiral thrust is as big as possible in the component of the axis direction of driving screw 12, substantially increases the feeding ability of extruder, improves machine
The board ability of platform, so as to be favorably improved the quality of extruded product, improve production efficiency, improves enterprise in the market
Competitiveness.
To solve the problems, such as the overflow of extruder vent, the problem to being probably exhaust ports design presence, to exhaust outlet
Structure is improved, and the size of designed exhaust outlet should be more wider than the width of stream, thereby may be ensured that extruder
The melt sizing material that exhaust outlet is not flowed is blocked, and simultaneously, the width of extruder steam vent also should not be too big, it is therefore an objective to
In order to shorten the possibility of sizing material residence time and sizing material expansion；When sizing material flows through the exhaust section of extruder, due to exhaust segment body
Product increases suddenly, pressure reduction, causes the air molecule in flowing sizing material, hydrone and lower-molecular substance to escape, from exhaust
Taken away by vavuum pump in hole；As shown in figure 3, vacuum extractor includes anti-overflow exhaust apparatus 26, in order to prevent sizing material from exhaust
Hole is emerged, and partly added with a shaftless screw 29 on steam vent, the drive device of this exhaust apparatus can be directly small using one
Torque motor III 27, is not used in configuring reduction box, and exhaust apparatus 26 is in the side of the direction of rotation of the screw rod, so that
Sizing material dumping is easy；The free end of shaftless screw 29 is connected by shaft coupling 28 with motor III27, the vavuum pump 43 with motor
It is connected with the glue case 33 of depositing in anti-overflow exhaust apparatus 26 by pump-line, during operation, motor III27 drives shaftless screw
29, shaftless screw 29 rotates formed spiral thrust and prevents sizing material melt overflow, because shaftless screw 29 and sizing material contact surface
Product is smaller, it is possible to larger resistance is formed to lower section sizing material, even if there is sizing material to emerge, it is also possible in material storing box 33 from the side
The sizing material emerged is taken out；Meanwhile, vavuum pump 43 runs, and gas passes through the row of blast pipe 32 from the intermediate hollow of shaftless screw 29 section
Gas, vacuum extractor realizes the exhaust of sizing material and anti-overflow function simultaneously；It should be noted that glue case 33 is deposited in Fig. 3 should use
Drawer-type structure in the prior art, in time to remove the sizing material emerged.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Various modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where spirit or scope of the present utility model are not departed from.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
