Row in the present invention be by it is horizontal for row erect be row rule, agreement in identical vertical position through hole for one row；
Next column through hole positioned at the single rotation direction position of the row through hole refers to, after a row ventilation, close to next column start ventilation, with this
Analogize, last each row are ventilated order by the clockwise direction arrangement of material trough, or each row are by the counterclockwise of material trough
Direction arranges ventilation order.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the material in material trough is heated by top cover, the material being heated starts to soften, the gap between such material
Start to make up, and under the Action of Gravity Field of top cover and motor, material can also be progressively compacted, some material meetings for softening
Flowed gradually downward by the gap of storeroom, the height of material can be tapered into, the material for now mainly changing is and top
Cover the part material of contact；
2nd, actuating unit drives material trough rotation, and such material will be subject to centrifugal action, and the material in material trough can be gradually
It is close to material groove sidewall, including the softening material for flowing from top to bottom also can gradually to material groove sidewall；After top cover is moved down, open
Dynamic motor, in the presence of motor, material at material trough gyroaxis can be held and be formed by directly exclusion
Emptying aperture, the material that so upper place softens directly can enter into material bottom along the inwall of bull stick or hollow hole；Now lead
The material to be changed is located at material trough gyroaxis the i.e. material at middle part；
3rd, air pump and in the presence of electric control valve, the material will not be fully adhered to by the airflow function from through hole
On the side wall of material trough；Limited hole is that a row connect being inflated in material trough for a row, is received in order to avoid inflating to allow together
It is rapidly achieved high pressure conditions in the material trough that top cover is covered, influence top cover and bull stick are moved down（Although top cover is to cover
Be not to be tightly connected at material trough, but throughput in material trough it is excessive can also influence top cover move down speed）, so that
The hollow hole for allowing material middle part to form predetermined depth or cannot be delayed；Because actuating unit, air pump are basic startups simultaneously,
The centrifugal action（Effect of the material by proximal wall）With the effect of the ventilation（Material should not be fitted the effect of side wall）It is
Synchronous generation, if two kinds of effects are suitable, equal to cancelling out each other, this is also not allow all through holes to be ventilated simultaneously why
Reason；But if simply disorderly allowing air-flow by through hole, some material sticks is understood unavoidably in material groove sidewall, so limit
Surely it is by certain rotation direction（Up time or inverse time）Through hole is allowed to be ventilated successively, it specifically considers as follows：As known to the public, material quilt at
When air-flow blows, the material of its adjacent can be subject to any influence of air-flow, and adjacent thing is blown and if then
Material, the adjacent material can be also easier to blow, and the difficulty for blowing material is reduced to a certain extent；On the other hand institute is used
The design of rotation direction is stated, that is, means that any row through hole will wait one week（Complete the venting process of a week）Could lead to again
The internal pressure of effective control material groove is capable of in gas, the control of this rhythmicity.
Further, in stepb, the bull stick is heated in the lump while heating to the top cover, makes bull stick and top cover
Temperature it is identical.
The bull stick is hyperpyrexia bull stick, and such bull stick not only acts as the effect of discharge, moreover it is possible to which the material at gyroaxis is straight
Connect and be changed into softening material, and because at once high temperature action, the material near bull stick can soften, the material after softening there is no fear of
It is close to bull stick, but can flows to elsewhere, or because centrifugal action is shifted to material trough outer wall, or because gravity is made
Shifted with to material trench bottom, so as to be distributed in the overall structure of material, it is to avoid appearance part is completely embedded and part is loose
Non-uniform phenomenon.The effect of hyperpyrexia bull stick herein is not stirring of the prior art, is not only sizing, it is often more important that make yet
The material UNICOM up and down at two of material, leads to hyperthermal direction, allow connection position produce it is a large amount of soften materials, by centrifugal action
The material of softening will be allowed to enter into the circumferential position of material, so that the product of last shaping is global formation, be not in office
The dry and cracked phenomenon in portion；And joint more fastens than stamping forming.
Further, order of the actuating unit by up time half-turn with inverse time half-turn alternately drives the material trough certainly
Turn.
In order to avoid flexible pipe occurs excessive wrapping phenomena when material trough is rotated, the actuating unit is at most only with material trough
Half-turn is rotated by a rotation direction.
Further, the actuating unit is persistently to drive material trough rotation by single rotation direction, and the air pump is fixed on the thing
In the outside bottom surface of hopper.
There is excessive wrapping phenomena when material trough is rotated to prevent flexible pipe, and to allow the material trough can be in single rotation direction
It is upper lasting to rotate, just air pump is fixed in the outside bottom surface of the material trough, air pump and flexible pipe is rotated with together with material trough.
Further, the bull stick is provided with wedge surface, and the wedge surface extends to the top of bull stick from the lower end of bull stick.
It is, in order to increase the heating area of bull stick, to increase its heating efficiency to increase wedge surface, because bull stick is to rotate, so
The size of hollow hole caused by bull stick will not be influenceed due to the presence of wedge surface.
Further, with the mutual UNICOM of the flexible pipe that same row through hole is connected.
Allow the material of material trough side-walls can not to produce buckling phenomena by uniform stressed, it is special by the connection of same row through hole
The mutual UNICOM of flexible pipe, realize that the admission pressure of each through hole of same column is identical.
