Description
Technical field
The invention belongs to the technical fields of plastic extruder, specifically disclose a kind of plastic extrusion apparatus.
Background technique
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, will lead to filter screen blocking, and replace filter screen and then need first to remove filter element, then will
Filter screen takes out replacement, this will lead to extruder shut-down, reduces the efficiency of production.
Summary of the invention
The purpose of the present invention is to provide a kind of plastic extrusion apparatus, need to make plastic extruder to solve replacement filter screen
Problem out of service.
In order to achieve the above object, base case of the invention are as follows: plastic extrusion apparatus, including pipe, feed pipe are squeezed into, also
Including reversing unit, squeeze out unit and communicating pipe, the feed pipe with squeeze into pipe and be slidably connected, the outer wall for squeezing into pipe is equipped with
Square groove, square groove is interior to be equipped with spring, is connected with semicircular convex block 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 equipped with first in first groove and open far from pipe is squeezed into
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 feed pipe is arranged in far from the one end for squeezing into pipe in second discharge nozzle, 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 to communicating pipe.
The working principle of this base case is: mobile feed pipe enters convex block 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 entering 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 in communicating pipe from the first discharge nozzle and the first extruding pipe, the plastics meeting flowed at this time
Push feed pipe mobile, 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 in the second extruding pipe by the second discharge nozzle, by entering 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 beneficial 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 in communicating pipe by the first discharge nozzle and the first extruding pipe, simultaneously
Second filter screen is mounted on the second extruding pipe, and the second extruding pipe is detachably connected in communicating pipe, and the second extruding pipe with
The separation of second discharge nozzle influences the first discharge nozzle and the so can disassemble and be cleaned without 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 is using feed pipe as center axial symmetry, and two extrusion units are using feed pipe as center axial symmetry.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, both can reduce first and squeezed
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 guarantee 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 device is close to the first motor-driven valve or the second motor-driven valve.After the present apparatus stops working, the first discharge nozzle and
Some plastics can be remained in second discharge nozzle, solid can be condensed into after plastics are cooling, by the first motor-driven valve and the second motor-driven valve
It blocks, it is caused to fail to open, and use this programme after the first motor-driven valve and the second motor-driven valve are blocked, starting heating fills
It sets, 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, and strut is also solid with extruding pipe
It connects.After the blocking of the first filter screen, 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 to 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, can also be played some supports communicating pipe to the first extruding pipe and the second extruding pipe and be made
With, but being also possible that communicating pipe can shake, and this programme is used, it is fixed on communicating pipe and is squeezed on pipe by strut, then kept away
The problem is exempted from.
