Description
Technical field
The utility model belongs to plastics machinery technical field, and in particular to does not have to shut down in a kind of plastic extrusion production process
That is the plastic extruder of replaceable filter screen.
Background technology
In plastic extrusion production, quality product is obtained in order to filter out impurity, filter net device is essential, while filter screen fills
The counter-pressure that putting can also play a part of increasing logistics makes product press closely knit to prevent non-plastifying material from entering head, with
Impurity screening increases, and the pressure before screen pack increases, and extrusion capacity reduces, and at this moment just needs during production run often more
Screen pack is changed, operating personnel will manually be loaded and unloaded to filter net device, pay heavy manual labor, while also result in former material
Expect the waste of serious waste and electric energy.
The content of the invention
The purpose of this utility model is to provide a kind of plastic extruder having filter screen replaced without shutdown, mitigates the physical labor of operating personnel
It is dynamic, improve production efficiency.
To achieve the above object, the technical solution of the utility model is：Plastic extruder having filter screen replaced without shutdown, including machine
Cylinder, head, mould, power set and strainer body, power set are connected on the top surface of machine barrel by support bar, under the machine barrel
End opening, the both ends of machine barrel are connected with head and mould respectively by ring flange, and the strainer body is deep into from the top of machine barrel
It in machine barrel, and can be stretched out at machine barrel lower ending opening, more than two filtering modules, wherein lower end are provided with the strainer body
Filtering module be arranged at the pipeline opening in machine barrel, strainer body is connected with the power set, is additionally provided with machine barrel and machine
The connecting hole that tube inner chamber communicates, connecting hole are tightly connected pressure sensor, and pressure sensor is connected with comparator, the comparator
It is connected with microprocessor, microprocessor is connected with voice guard and the power set.
Preferably, the power set are hydraulic cylinder.
The beneficial effects of the utility model are：The utility model is simple in construction, and pressure sensor can detect machine barrel in real time
The size of interior cavity pressure, then compares with setting value, when the pressure of machine barrel inner chamber exceedes setting value, microprocessor control liquid
Cylinder pressure driving strainer body action, upper end filtering module is moved downwardly to be continuing with pipeline opening, therewith lower end filtering module to
Lower move simultaneously is stretched out outside machine barrel, therefore need not shut down just lower end filtering module can be cleaned, and improves operating efficiency, is dropped
The low amount of labour of staff.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model；
Fig. 2 is that the right side of the utility model strainer body regards structural representation.In figure：
1st, head, 2. machine barrels, 3. voice guards, 4. comparators, 5. pressure sensors, 6. microprocessors, 7. power dress
Put, 8. strainer bodies, 9. moulds, 10. support bars, 11. filtering modules.
Embodiment
As shown in Figure 1-2, plastic extruder having filter screen replaced without shutdown, including machine barrel 2, head 1, mould 9, the and of power set 7
Strainer body 8, power set 7 are connected to by support bar 10 on the top surface of machine barrel 2, the lower ending opening of machine barrel 2, and the two of machine barrel 2
End is connected with head 1 and mould 9 respectively by ring flange, and the strainer body 8 is deep into machine barrel 2 from the top of machine barrel 2, and energy
It is enough to be stretched out at the lower ending opening of machine barrel 2, it is provided with more than two filtering modules 11, the wherein filtering of lower end on the strainer body 8
Module 11 is arranged at the pipeline opening in machine barrel 2, and strainer body 8 is connected with the power set 7, and the power set 7 can be
Hydraulic cylinder；
The connecting hole communicated with the inner chamber of machine barrel 2 is additionally provided with machine barrel 2, connecting hole is tightly connected pressure sensor 5, pressure
Sensor 5 is connected with comparator 4, and the comparator 4 is connected with microprocessor 6, and microprocessor 6 is connected with the He of voice guard 3
The power set 7.
When needing to clean or changing using a period of time screen pack, it is only necessary to start hydraulic cylinder, in the work of hydraulic stem
Under, strainer body moves downward, and upper end filtering module is moved downwardly to be continuing with pipeline opening therewith, and lower end filtering module
Stretched out in the presence of hydraulic stem at the lower ending opening of machine barrel 2, therefore need not shut down and the filtering module of lower end can just be carried out
Cleaning, the energy has been saved with manually, has improved operating efficiency；
Pressure sensor 5 can in real time in detection machine tube inner chamber pressure size, then compare with setting value, when machine barrel 2
When the pressure of inner chamber exceedes setting value, microprocessor 6 controls Driven by Hydraulic Cylinder strainer body 8 to act, and by pending filter module
Block 11 is stretched out outside the machine barrel 2, so that attendant is cleared up.Operating efficiency is improved, reduces the labor of staff
Momentum；In addition, when the pressure in machine barrel 2 is above standard value, voice guard 3 can all play warning function；Prompting maintenance people
Member is cleared up stretching out the filtering module 11 outside machine barrel.
It is those skilled in the art known technology in addition to technical characteristic described in specification.
