Description
Technical field
The invention belongs to the technical fields of plastic extruder, specifically disclose a kind of plastic extrusion apparatus.
Background technology
Plastic extruder includes driving mechanism, feed inlet and extrusion screw rod, and driving mechanism driving extrusion screw rod slowly runs,
So that the plastic spiral near extrusion screw rod advances, plastics will be filtered after being extruded by filter element, in filter element
It is provided with filter screen.After having used filter element every time, wherein remaining plastics will be cooled down gradually, filter element is reused
When, the plastics of thawing by the plastic heating cooled down in filter element and can make its thawing, after filter element is used for a long time, filter screen
Upper remaining plastics are more and more, filter screen can be caused to block, and replacing filter screen then needs first to remove filter element, then will
Filter screen, which takes out, to be replaced, this can cause extruder to be stopped work, and reduce the efficiency of production.
Invention content
The purpose of the present invention is to provide a kind of plastic extrusion apparatus, need to make plastic extruder to solve to replace filter screen
The problem of out of service.
In order to achieve the above object, base case of the invention is：Plastic extrusion apparatus, including squeezing into pipe, feed pipe, also
It is slidably connected including reversing unit, extrusion unit and communicating pipe, the feed pipe with squeezing into pipe, the outer wall for squeezing into pipe is equipped with
Square groove, square groove is interior to be equipped with spring, and semicircular convex block is connected on spring, is provided on the inner wall of feed pipe and convex block matches
The first groove and the second groove closed, the position of first groove are opened far from pipe is squeezed into first groove equipped with first
It closes, second switch is equipped in second groove；The reversing unit include the first discharge nozzle and the second discharge nozzle, described first
Discharge nozzle is arranged in the middle part of feed pipe, and second discharge nozzle is arranged on feed pipe far from the one end for squeezing into pipe, and described first goes out
Expects pipe and the direction of the second discharge nozzle are on the contrary, the first discharge nozzle is equipped with the first motor-driven valve, the first motor-driven valve and first switch electricity
Connection, the second discharge nozzle are equipped with the second motor-driven valve, and the second motor-driven valve is electrically connected with second switch；The extrusion unit includes the
One extruding pipe and the second extruding pipe, first extruding pipe is directed at the first discharge nozzle and the first extruding pipe is equipped with the first filtering
Net, second extruding pipe is directed at the second discharge nozzle and the second extruding pipe is equipped with the second filter screen, the first extruding pipe and second
Extruding pipe is detachably connected with communicating pipe.
The operation principle of this base case is：Mobile feed pipe makes convex block enter in the first groove in advance, and convex block is pressed
First switch is pressed, first switch is opened so that the first motor-driven valve is opened, and the first discharge nozzle is inserted into the first extruding pipe, while the
Two motor-driven valves are closed, and the second discharge nozzle and the second extruding pipe are separated from each other.By after plastic extrusion, plastics enter crowded extrusion screw rod
Enter in pipe, enter back into feed pipe, since the second motor-driven valve is closed, so plastics can only enter the by the first discharge nozzle
In one extruding pipe, by being entered back into after the first filter screen into communicating pipe, then flowed out out of communicating pipe.When the first filter screen blocks
Afterwards, the plastics in feed pipe can not be flow to from the first discharge nozzle and the first extruding pipe in communicating pipe, the plastics meeting flowed at this time
Feed pipe is pushed to move, the convex block on feed pipe is squeezed, and spring-compressed, convex block can be forced into square groove, and first switch is closed
It closes, the first motor-driven valve is closed, and when the convex block on feed pipe is moved in the second groove, second switch is pressurized, and second switch is beaten
It opens, the second motor-driven valve is opened, and plastics are entered by the second discharge nozzle in the second extruding pipe, by being entered back into after the second filter screen
Into communicating pipe, flowed out out of communicating pipe.The first extruding pipe is disassembled at this time, the first filter screen is cleaned up, then will
First extruding pipe was installed on communicating pipe.
The advantageous effect of this base case is：When the first discharge nozzle and the first extruding pipe are in conveying plastics in this programme
When, the second motor-driven valve is closed, so plastics can only be entered by the first discharge nozzle and the first extruding pipe in communicating pipe, simultaneously
Second filter screen be mounted on the second extruding pipe on, the second extruding pipe detachably connection in communicating pipe, and the second extruding pipe with
Second discharge nozzle detaches, and be cleaned without influencing the first discharge nozzle and the so can disassemble the second extruding pipe
As soon as the normal work of extruding pipe, filter screen can be cleaned or replace without shut-down inspection by realizing.
Preferred embodiment one：It is set on the feed pipe there are two identical reversing unit and squeezes out unit, and two commutations are single
Member axial symmetry centered on feed pipe, two extrusion unit axial symmetry centered on feed pipe.Since the hardness of filter screen is inadequate,
If the area of filter screen is excessive, under the impact of a large amount of plastics, filter screen is easy to damage, but the area of filter screen is too small
Then influence the conveying capacity of plastics.Using this programme, then another reversing unit is set and squeezes out unit, can both reduced first and squeeze
The diameter of outlet pipe and the second extruding pipe reduces the area of the first filter screen and the second filter screen, and can ensure the conveying of plastics
It measures unaffected.
Preferred embodiment two：Preferably one it is preferred, be equipped on first discharge nozzle and the second discharge nozzle plus
Thermal, the heating unit is close to the first motor-driven valve or the second motor-driven valve.After the present apparatus is stopped, the first discharge nozzle and
Some plastics can be remained in second discharge nozzle, solid can be condensed into after plastics cooling, by the first motor-driven valve and the second motor-driven valve
It blocks, causes it that can not open, and use this programme after the first motor-driven valve and the second motor-driven valve are blocked, start heating and fills
It puts, by plastic melt.
Preferred embodiment three：As the preferred of basic scheme, the place of being slidably connected for squeezing into pipe and feed pipe is equipped with sealing
Circle.It can prevent plastics from flowing out from squeezing into the gap between pipe and feed pipe using this programme, enhance its leakproofness.
Preferred embodiment four：As the preferred of basic scheme, described squeeze into is connected with strut on pipe, strut is also consolidated with extruding pipe
It connects.After the first filter screen blocks, feed pipe can be pushed to the second extruding pipe.Feed pipe can for some time with the first extruding pipe
It is not connected with the second extruding pipe, although being typically inserted into communicating pipe in subsequent plastic forming device, plastic forming device
Some supporting roles can be played to communicating pipe, some supports can be also played communicating pipe to the first extruding pipe and the second extruding pipe and make
With, but being also possible that communicating pipe can shake, and using this programme, it is fixed on communicating pipe and is squeezed on pipe by strut, then kept away
The problem is exempted from.
