Description
Technical field
The utility model is related to a kind of sheet extruder technology, specifically a kind of sheet extruder is not shut down moves strainer certainly
Device.
Background technology
Sheet extruder after plastic molting is at melt, passes through screw rod by die head extrusion sheet under conventional control operation
The plastics of fusing are sent to die head by mechanism or feed mechanism, due to containing impurity in the plastics of fusing, can cause the blocking of die head,
Therefore generally filter net device can be set between feed mechanism and die head, and strainer is in use for some time on strainer
Filter opening can be slowly to block, it is therefore desirable to need to shut down when regularly replacing strainer, and replacing strainer, be opened again again after the completion of replacing
Machine, needs longer preheating time after turning back on, so largely effect on the connectivity and efficiency of production, also result in simultaneously
The increase of energy consumption.
Utility model content
It does not shut down the purpose of this utility model is to provide a kind of sheet extruder and changes filter net device, strainer uses web-like mistake
Strainer realizes that strainer does not shut down automatic replacement, ensures the continuity of extruder work, reduce the loss of energy consumption, and improve work
Make efficiency.
Following technical scheme is used to achieve the above object：
A kind of sheet extruder does not shut down automatic filter screen change device, it is characterised in that：Including link block and web-like strainer,
The link block is arranged between the screw rod and die head of extruder, is provided with screw rod in link block and what die head communicated send
Expect that channel, link block also set up the strainer channel through link block and with feeding passage vertical connection, web-like filter
In strainer passage end mouth, the end of web-like strainer enters from strainer channel network access end and from the other side in strainer channel for net setting
Network outlet is pierced by；The position that feeding passage is corresponded to inside the link block is provided with the first heating zone；In link block
The second heating zone is arranged from feeding passage to the position at link block network access end in inside, the first heating zone and the second heating zone plus
Thermal is controlled by controller.
The thickness at strainer channel networking end and the thickness of strainer matches, and the thickness of strainer channel other positions is slightly
More than the thickness of strainer.
Third heating zone is set from feeding passage to the position of link block network outlet inside the link block,
Reel wire device is additionally provided on the outside of link block network outlet.
The strainer of web-like is arranged in the side of link block in the utility model, and the plastics of fusing need when passing through feeding passage
Filtering through filter screen, so that it is guaranteed that impurity is filtered；The utility model from strainer is moved by two ways, wherein the first
It is pulled by reel wire device, another kind is that fusing plastics push strainer toward network outlet in pressure in feeding passage, to realize
Automatic more net, the utility model screen replacing are automatically performed, without stopping in more network process, to ensure the company of extruder work
Continuous property, reduces the loss of energy consumption, and improve working efficiency.

Fig. 2 is the internal structure schematic diagram of the utility model first time draping mode；
Fig. 3 is the internal structure schematic diagram of second of draping mode of the utility model.
Specific implementation mode
As shown in Figs. 1-3,
A kind of sheet extruder does not shut down automatic filter screen change device, it is characterised in that：Including link block 1 and web-like strainer
2, the link block 1 is arranged between the screw rod and die head of extruder, and screw rod is provided in link block 1 and die head communicates
Feeding passage 11, link block 1 also set up through link block and with the strainer channel 12 of 11 vertical connection of feeding passage, institute
The setting of web-like strainer 2 stated in 12 Single port of strainer channel, the end of web-like strainer 2 enter from 12 network access end of strainer channel and from
The other side network outlet in strainer channel is pierced by；The position that feeding passage is corresponded to inside the link block 1 is provided with first
Heating zone 5；Inside link block 1 from feeding passage 11 to the position at link block network access end be arranged the second heating zone 6, first
The heating device of heating zone 5 and the second heating zone 6 is controlled by controller.
The thickness at 12 networking end of strainer channel and the thickness of strainer matches, the thickness of 12 other positions of strainer channel
Thickness of the degree slightly larger than strainer.
The strainer of web-like is arranged in the side of link block in the utility model, and the plastics of fusing need when passing through feeding passage
Filtering through filter screen, so that it is guaranteed that impurity is filtered；The automatic draping process of the utility model is such：Usually the second heating
Area is in the state of cooling, and the plastics of fusing enter strainer and 12 gap of strainer channel, since link block is located at feeding passage
The region of both sides is in the state of cooling, the cooled solidification of the plastics melted in this way, and the effect of both sides is mutually balanced, thus risen
To the effect of sealing, prevent the plastics dissolved excessive；And when draping, the second heating zone is heated the plastic molting in the region, this
When link block inside fusing plastics pressure act on network outlet solidification plastics on, since this partly plastic is to be set in filter
On the net, so that the active force of the both sides of the strainer in strainer channel 12 is uneven, therefore strainer can be from trend network outlet one
Side is moved, and after strainer moves a distance, the second heating zone powers off cooling under control of the controller, and net filter at this time restores again
Automatic draping work is so far completed to equilibrium state.
In addition another draping mode also can be used in the utility model：
From feeding passage 11 to the position of link block network outlet setting third heating zone inside the link block 1
7, it is additionally provided with reel wire device 3 on the outside of 1 network outlet of link block.
This draping mode gradually draws strainer from network access end and network outlet by the way that net drum is intermittent, while this practicality
Novel strainer in order to prevent is smoothly replaced, and second and third heating zone are respectively set in the both sides of the first heating zone, and second and
It can will be set in the plastic molting of the part after the heating of three heating zones, such strainer reel wire device ability stretchy strainer, usually the
Two and third heating zone be in the state of cooling, be expressed to plastics freeze in strainer and strainer channel from feeding passage in this way
To natural sealing effect, at the same with play to strainer fixed function.
