Description
Technical field
It the utility model is related to the parts of plastic extruder, and in particular to a kind of plastic extruder with multistorey strainer mesh
Screen replacing mechanism.
Background technology
Filter screen in conventional plastic extruder, all it is to be assemblied in threeway lid, then threeway lid passes through screw and three-way body
Mutually it is fixedly connected, for plastic extruder in the course of work of extrusion plastic, filter screen is to be easy to be blocked up by the impurity in raw material
Plug, and the cleaning replacement of filter screen must shut down progress, it is not only cumbersome, and power consumption is big, and yield rate is low, the patent No.
200620074170.5 disclosing fast replacing mechanism for plastic machine filter screen altogether, its technical scheme used is to include movable sleeve
Three-way body and threeway lid, assemble filter screen in threeway lid, the discharging opening of threeway lid and three-way body to go out merely mouth relative, threeway lid
Rear end is mutually fixed with screw rod, and the nut being engaged with screw rod is fixed in bearing block by bearing, the rear end of nut and driving-chain
It is connected, it is only necessary to which rotating nut, screw rod just drive threeway lid to be separated with three-way body, the cleaning replacement with regard to that can be rapidly performed by filter screen
Operating, the filter screen in this structure can only carry out coarse filtration to the plastics being extruded, although quick-replaceable filter screen can be carried out,
But the filter effect of this filter screen is not ideal.
Utility model content
Technical problem to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art,
A kind of screen replacing mechanism of the plastic extruder with multistorey strainer mesh is provided.
To achieve the above object, the utility model provides following technical scheme：A kind of plastics with multistorey strainer mesh squeeze
Go out the screen replacing mechanism of machine, include the relative frame set up, it is characterised in that：Three-way body is fixedly connected with the frame
And bearing block, the three-way body rear end is provided with threeway lid, the discharging opening of the threeway lid simultaneously shape relative with the discharging opening of three-way body
Into a filter screen cavity volume, the threeway cover back-end is provided with screw rod, and the screw rod passes through screw and threeway with respect to one end of threeway lid
Cover back-end connects, and the screw rod is provided with the nut supporting with screw rod, and the nut is fixed in bearing block by bearing, described
Nut back end is arranged with drive sprocket, and the plastics of extrusion can be carried out to the multiple filtration net group of careful filtering in the filter screen cavity volume
Part, the screen modules include front end screen pack, supporting plate and rear end screen pack, the mesh of filter screen in the front end screen pack
Number is less than the mesh number of filter screen in the screen pack of rear end, is provided with and front end screen pack mesh number identical filter screen in the middle part of the supporting plate..
Using above-mentioned technical proposal, multiple filtration screen component is set in filter screen cavity volume, before the use of multiple filtration screen component
The setting of screen pack, supporting plate, rear end screen pack is held, mesh of the mesh number of filter screen than filter screen in the screen pack of rear end in the screen pack of front end
Number is small, that is to say, that the Kong Yao great of the boring ratio rear end filter screen of front end filter screen, the benefit so set were filtered by first time
Plastics namely after the screen pack of front end again pass by second of filtering of rear end filter screen, contain after filtering in plastics
Impurity is less, and filtering is finer.
A kind of screen replacing mechanism of above-mentioned plastic extruder with multistorey strainer mesh can be further arranged to：The branch
Fagging is provided with support bar relative to the one side of front end screen pack, and the support bar abuts against with front end screen pack.
Using above-mentioned technical proposal, the support bar set on the supporting plate, which can prop up front end filter screen, to be come, because squeezing
During going out, plastics have the pressure pushed away inward, if screen pack does not support, can inward be pressed, cause filter effect to subtract
It is weak.
A kind of screen replacing mechanism of above-mentioned plastic extruder with multistorey strainer mesh can be further arranged to：The branch
Stay is provided with claw.
Using above-mentioned technical proposal, the claw set on support bar can be connected to front end by the hole of front end screen pack
On screen pack, support effect is more preferable.
A kind of screen replacing mechanism of above-mentioned plastic extruder with multistorey strainer mesh can be further arranged to：Described three
Tong Gai front ends are provided with screen support post, and the screen support post is provided with rear end screen pack claw.
Using above-mentioned technical proposal, the screen support post and rear end filter screen claw set in threeway lid front end is played and supported
The same function of support bar and claw on plate, and prevent that rear end screen pack from the presence of material, being pushed away inward, so as to cause
Rear end filter effect is not fine.
The beneficial effects of the utility model are：Filter effect is more preferable, only needs rotating nut, the threeway lid under the drive of screw rod
It can be separated with three-way body, replacing or the cleaning operation of filter screen, simple in construction, extrusion efficiency can be easily carried out after separation
Height, it is highly reliable the advantages of.
The utility model is described in further detail with reference to the accompanying drawings and examples.
