Specific implementation mode
For technology contents, construction feature, institute's reached purpose and effect of utility model is described in detail, below in conjunction with implementation
Example simultaneously coordinates attached drawing to be described in detail.Wherein, shown in the position relationship up and down described in the present embodiment and attached drawing 1
The position relationship up and down for vacuumizing material-blockage preventing device is corresponding；" fluorubber " described in the present embodiment refers to main chain or side
Synthesis macromolecular elastomer containing fluorine atom, the chemical stability with height on the carbon atom of chain are current all bullets
Best one kind of medium-resistance in property body.
With reference to the accompanying drawings shown in 1, it includes vacuum system 1, Anti-blockage mechanism 2 and control that this, which vacuumizes material-blockage preventing device 100,
Unit.Wherein, vacuum system 1 includes cooler 11, filter 12, vacuum pump 13 and the air accumulator being sequentially connected by pipeline
14；Cooler 11 has an air inlet 111 and gas outlet, and gas outlet is connected with filter 12.Anti-blockage mechanism 2 includes a four-way
Pipe fitting 21, this four-way pipe fitting 21 have one for be connected with plastic extruder feed inlet 211, a discharge port 212 and
Two discharge gates 213, wherein feed inlet 211 and discharge port 212 the two oral areas are oppositely arranged, and are for the ease of working as machine barrel in this way
There is material when exhaust outlet overflow, that is, inside four-way pipe fitting 21 into fashionable, material drops into four-way pipe due to its own gravity
The bottom of part 21, and steam then by vacuum system 1 taken away by the discharge port 212 above four-way pipe fitting 21, feed inlet 211 and discharging
212 this height falls of mouth can extend the time of material filling pipeline, be more conducive to the cleaning operation of user.In this implementation
In example, 21 inside of four-way pipe fitting is straight-through structure, and two discharge gates 213 are located at the top and bottom of four-way pipe fitting 21, this
Kind structure is more advantageous to the cleaning and discharge of material.In addition, being mounted on boring cover 214, each discharge gate on two discharge gates 213
Gasket is provided between 213 and boring cover 214, in the present embodiment, which is made of fluorubber material, so,
It can ensure the required degree of hollowness in 21 inside of four-way pipe fitting.For the ease of being taken away inside Anti-blockage mechanism 2 using vacuum system 1
It is connected with exhaust tube 22 between the air inlet 111 of steam, discharge port 212 and cooler 11, is provided on discharge port 212 for controlling
The valve 23 of 22 on/off of exhaust tube processed is provided with for detecting in four-way pipe fitting 21 whether have material on one of boring cover 214
Sensor 24；The alarm module that control unit includes a control mainboard, is connect with this control mainboard signal, sensor and control
Mainboard signal connects.In the present embodiment, valve 23 is ball valve.In other embodiments, valve can also be believed with control mainboard
Number connection, pass through sensor detect four-way pipe fitting materials inside situation, the on/off of control mainboard autocontrol valve.
The operation principle for vacuumizing material-blockage preventing device 100 is as follows：When the exhaust outlet overflow of extruder barrel, material passes through
Feed inlet 211 enters in four-way pipe fitting 21, material due to dead weight under fall on the bottom of four-way pipe fitting 21, and steam is then from top
Discharge port 212 is taken away by vacuum system 1；Sensor 24 on the lowermost boring cover 214 detects depositing inside four-way pipe fitting 21
Control mainboard is fed back in material, and by this signal, control mainboard sends signal to alarm module, and alarm module generates alarm and carries
The user that wakes up executes cleaning operation, and user first closes ball valve, to cut off vacuum system, then opens the boring cover of 21 lower end of four-way pipe fitting
214 can come out material from four-way pipe fitting internal cleaning, and in actual production overshoot, whole operation flow only needs 15 minutes
