Abstract
A filter replacing device of extruding machine is characterized in a piece of feeding plate (2) connected with the anterior end (1) of an extruding machine barrel and containing a melter guide part (3), a filter mesh support plate (5,7) respectively provided with a filter mesh (4,6), a piece of discharge plate (10) with an exhaust hole (9) connected with the extruding machine head or other parts (not seen in the figure) and containing a melter guide part (13). Wherein, when the melter guide parts (3) and (13) close and open a channel (N) and a channel (M), the melter fully goes through the channel (M) and the filter mesh (6) and flows to the machine head, and at the same time or afterwards goes through a relax bolt (11) or other fasteners, so that the filter mesh support plate (5) is taken out, and the filter mesh (4) is replaced or cleaned; when the melter guide parts (3) and (13) close and open a channel (M) and a channel (N), the melter fully goes through the channel (N) and the filter mesh (4) and flows to the machine head, and at the same time or afterwards goes through a relax bolt (8) or other fasteners, so that the filter mesh support plate (7) is taken out, and the filter mesh (6) is replaced or cleaned.
Description
Technical field
The utility model relates to a kind of macromolecular material processing and forming machinery device, particularly a kind of extruder filter replacement mechanism.
Background technology
Extruder is the important plant equipment of macromolecular material or its mixture manufacturing or processing and forming, and in order to obtain high-quality product, people usually install screen pack in the front portion of extruder, to filter the impurity of institute's strap clamp in macromolecular material or other raw materials.So far existing various screen packs or filter screen device get up substantially only to have two classes but conclude: must shut down and change screen pack and do not shut down the screen replacing device.Because extruder is continuously a production equipment ceaselessly; if settle to shut down and change filter screen device; extruder just has to shut down often to change filter screen, cause that extruded product quality instability and productive rate descend, so the present extruder of settling palpus to shut down the replacing screen pack is fewer and feweri.Not shutting down the screen replacing device has two kinds substantially, and a kind of is the net exchanging device that brings to few two stations, and another kind is only with the screen replacing device of a station (but detachable one-tenth two).
Chinese patent CN89218733.6 discloses a kind of fluid pressure type two station net exchanging devices, and it is handled by a hydraulic cylinder, but between flow distribution plate in this device and station groove for movingly, easily produce and leak material, not phenomenon such as easy cleaning.CN2103425U disclose a kind of four stations are arranged do not shut down automatic net exchanging device, but its volume is quite big, also easily produces the excessive phenomenon of melt, and easy to clean defective material not.Chinese patent CN2567024Y discloses a kind of quick net exchanging device of sheet extruder, this device is located at the flow distribution plate front of the coupling assembling that is connected with machine barrel, comprise slide rail and the slide plate that slides thereon, and slide plate is provided with two screen packs that are used alternatingly and flow distribution plate passage, yet this device needs the bigger hydraulic-driven power that includes high energy fluid accumulator, and the filter screen dismounting and cleaning is cumbersome.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art fully by a kind of economical and practical technical scheme.
Distinguishing feature of the present utility model is: the extruder filter replacement mechanism that the utility model relates to is simple in structure, it can be used for not changing filter in the extruder at extrusion with shutting down; especially the melt pressure distribution fluctuates minimum in the extruder in the filter replacing process in the time of guaranteeing to extrude, thus the extruded product quality of stability further ensured.
The extruder filter replacement mechanism that the utility model relates to comprises a feedboard (2) that contains a melt guiding parts (3) that is connected with extruder barrel front end (1), each installs a screen pack (4,6) filter screen support plate (5,7), the reclaiming plate (10) of a band steam vent (9) that contains a melt guiding parts (13) that is connected with cross-head or other parts (not shown); Wherein, when melt guiding parts (3) and (13) are closed runner (N) and unlimited runner (M) simultaneously, melt passes screen pack (6) by runner (M) fully and flows to head, at this moment or after this pass through loose bolts (11) or other securing member, take out filter screen support plate (5), change or cleaning screen pack (4); When melt guiding parts (3) and (13) are closed runner (M) and unlimited runner (N) simultaneously, melt passes screen pack (4) by runner (N) fully and flows to head, at this moment or after this pass through loose bolts (8) or other securing member, take out filter screen support plate (7), change or cleaning screen pack (6).
Feedboard that the utility model relates to (2) or reclaiming plate (10) are monoblock type or many combined types.
The commutation action is carried out by manual, electronic, pneumatic or hydraulic-driven in the melt guiding parts (3) that the utility model relates to and (13), and they can interlock or each self-retention.
The utility model device can lead by manually slowly or fast carrying out materials flow, also can be by electronic, and pneumatic or hydraulic-driven is carried out the materials flow commutation.
