Configuration arrangement, if material trough surrounding arranges dry-air pump, air pump is consistent with the quantity of through-hole, then presses one-to-one mode,
Hose is connected between air pump and through-hole, and electric control valve, all electric control valves and same circuit drives are equipped between air pump and hose
Module electrical connection；Then material is placed into material trough, the material is by the smashed plastic grain of plastics defect ware；
B., driving motor is installed on top cover again, driving motor is equipped with bull stick, and the bull stick passes through the top cover, then
Top cover is heated, so that the temperature of top cover is reached 600 degree or more, while heating together to bull stick, so that bull stick and top cover
Temperature is identical；Then top cover is directly covered to conjunction on material, it is desirable that the bull stick is got involved in material trough, and the length of bull stick
The height initial less than material；Wherein top cover is matched with the notch shape size of material trough；
C. start above-mentioned power mechanism, air pump and circuit drives module, power mechanism drives material trough rotation, driving electricity
Machine drives bar rotation, and the electric control valve makes the through-hole of same row while ventilating under the regulation of the circuit drives module,
And in material groove sidewall after the through-hole of a certain column starts ventilation, the next column through-hole positioned at the single rotation direction position of the column through-hole is opened
Begin to ventilate；Start driving motor after top cover starts to move down, after bull stick arrives to material trench bottom, waits 20 to 30 minutes, then
Close the power mechanism and driving motor.
Column in the present invention be by it is horizontal be row erect be column rule, agreement in identical vertical position through-hole be one column；
Next column through-hole positioned at the single rotation direction position of the column through-hole refers to that after a column ventilation, adjacent next column starts to ventilate, with this
Analogize, last each column are the clockwise direction arrangement ventilation order by material trough, or each column are by the counterclockwise of material trough
Direction arranges ventilation order.
Compared with prior art, the beneficial effects of the present invention are:
1, the material in material trough is heated by top cover, heated material starts to soften, between such material
Gap starts to make up, and under the gravity of top cover and driving motor, material can be also progressively compacted, the object of some softenings
Material can be flowed gradually downward by the gap of storeroom, and the height of material can gradually become smaller, and the material mainly to change at this time is
The part material contacted with top cover；
2, power mechanism drives material trough rotation, and such material just will receive centrifugal force effect, the material meeting in material trough
Gradually close to material groove sidewall, the softening material including flowing from top to bottom also can be gradually to material groove sidewall；It is moved down to top cover
Afterwards, start driving motor, under the action of driving motor, the material at material trough rotating shaft can be held and shape by directly exclusion
At hollow hole, the material of place's softening upper so directly can enter material bottom along the inner wall of bull stick or hollow hole；This
When the material that mainly changes be located at material trough rotating shaft the i.e. material at middle part；
3, air pump and under the action of electric control valve, the material will not be glued completely by the airflow function from through-hole
It is attached on the side wall of material trough；Limited hole is that a column connect inflating into material trough for a column, is in order to avoid inflating meeting together
It allows in the material trough closed by top cover lid and is rapidly achieved high pressure conditions, influence moving down (although top cover only covers for top cover and bull stick
Close at material trough, be not be tightly connected, but ventilatory capacity in material trough it is excessive also will affect top cover move down speed),
To can not or delay the hollow hole for allowing material middle part to form predetermined depth；Since power mechanism, air pump are basic while being opened
Dynamic, the centrifugal action (effect that material leans on proximal wall) (allows material not be bonded the work of side wall with the effect of the ventilation
With) be synchronization, if two kinds of effects are quite, equal to cancelling out each other, this be also why do not allow all through-holes simultaneously
The reasons why ventilation；But if only disorderly allowing air-flow by through-hole, some material sticks is inevitably understood in material groove sidewall,
So limiting is successively through-hole to be allowed to ventilate by certain rotation direction (up time or inverse time), specifically consider as follows: as known to the public, at one
When material is blown by air-flow, the material of adjacent can be blown phase by any influence of air-flow and if then
Adjacent material, the adjacent material can also be easier to blow, and reduce the difficulty for blowing material to a certain extent；On the other hand
Using the design of the rotation direction, that is, mean that any column through-hole will wait one week (complete one week venting process) ability
It ventilates again, the control of this rhythmicity can effectively control the internal pressure of material trough.
In stepb, the bull stick is heated together while heating to the top cover, makes temperature phase of the bull stick with top cover
Together.
The bull stick is high fever bull stick, and such bull stick not only acts as the effect of discharge, moreover it is possible to which the material at rotating shaft is straight
Connecing becomes softening material, and due to high temperature action, and the material near bull stick can soften at once, and the material after softening there is no fear of
It is close to bull stick, but can flows to elsewhere, or since centrifugal action is to the transfer of material trough outer wall, or since gravity is made
It is shifted with to material trench bottom, to be distributed in the overall structure of material, avoids the occurrence of and be locally completely embedded and part is loose
Non-uniform phenomenon.The effect of high fever bull stick herein is not stirring in the prior art, is not only to be formed, it is often more important that make yet
The material connection at two up and down of material, leads to hyperthermal direction, allows connection position to generate a large amount of softening materials, passes through centrifugal action
The material of softening will be allowed to enter the circumferential position of material, be not in office so that last molding product be made to be integrally formed
The dry and cracked phenomenon in portion；And joint is more fastened than stamping forming.
Further, the power mechanism drives the material trough certainly by the order of up time half-turn and inverse time half-turn alternately
Turn.
In order to avoid excessive wrapping phenomena occurs when material trough rotates for hose, the power mechanism is at most only with material trough
Half-turn is rotated by a rotation direction.
Further, the power mechanism is that material trough rotation is persistently driven by single rotation direction, and the air pump is fixed on the object
In the outside bottom surface of hopper.
When material trough rotates excessive wrapping phenomena occurs for hose in order to prevent, and to allow material trough can be in single rotation direction
Air pump, is just fixed in the outside bottom surface of the material trough, rotates together air pump and hose with material trough by upper lasting rotation.
Further, the bull stick is equipped with wedge surface, and the wedge surface extends to the top of bull stick from the lower end of bull stick.
Increasing wedge surface is the heating area in order to increase bull stick, increases its heating efficiency, since bull stick is rotation, so
Will not due to wedge surface presence and influence the size of hollow hole caused by bull stick.
Further, the mutual connection of the hose being connect with same row through-hole.
Allow the material of material trough side-walls that can not generate buckling phenomena by uniform stressed, spy connects same row through-hole
The mutual connection of hose, realize each through-hole of same column admission pressure it is identical.
