Abstract
The utility model provides a filter screen changing device for a plastic extruding machine and an injection machine, mainly comprising flow distribution plates, a filter screen, the piston rod of an oil cylinder, and a front and a rear mold plates. A fixing frame is arranged between the front and the rear mold plates, the inner track is provided with a movable frame fixedly connected with the piston rod, and the interior of the frame is provided with four flow distribution plates. The contact surfaces of the side surfaces of the flow distribution plates and the front and the rear mold plates form an interference fit.
Description
The utility model relates to the improvement of plastics extruder injector net exchanging device.
At present; domestic plastics class extruder, the injector of using mostly adopts traditional flange opening type draping mechanism or plug formula draping mechanism; its draping is manual carrying out under stopped status; not only influenced normal production; and dress folding trouble; high-temperature operation labour intensity is big, and working condition is poor.A kind of fluid pressure type two station net exchanging devices are provided among the CN89218733.6, it has a transpositing plate of being handled by hydraulic cylinder, and two circular station grooves that flow distribution plate is installed are arranged on this transpositing plate, makes piston rod drive transpositing plate during draping and makes stretching motion, reach old plate is extracted out, change the purpose of new plate.This device has overcome that original net exchanging device labour intensity is big, and the draping time is long, needs the shortcoming of shutting down.But after this machine draping, the temperature of filter is lower than the web plate that is using because new plate reaches wherein, and usually is entrained with air, so quality of item is difficult to guarantee in a period of time after the draping, usually produces major defect, causes shutting down or partly shutting down; On the other hand, adopt movingly between the flow distribution plate of this device and the circular station groove, be easy to the seepage material, upgrade and clean inconvenience to some extent.
The purpose of this utility model is to provide a kind of fluid pressure type that can overcome above deficiency not shut down automatic net exchanging device, its draping automatically, and speed is fast, and is easy to operate, and can guarantee that quality of item is unaffected.
The purpose of this utility model is realized by following mode.
The utility model includes the piston rod that flow distribution plate that screen pack is installed links to each other with oil cylinder piston and reaches the front and back template that links to each other with logistics pipeline, on the template of front and back, respectively be provided with material runner hole, piston rod is fixedlyed connected with the push-and-pull activity box that flow distribution plate is installed, and it is characterized in that:
A) be provided with a fixed frame between the template of described front and back, on the track that the upper and lower inner surface of this framework constitutes, cooperate the push-and-pull activity box is installed, in the push-and-pull activity box, has the station that four flow distribution plates are installed at least, be respectively initial preparation station, pre-material station, work runner station and the station to be unloaded of dashing, be interference fit between flow distribution plate and the contacted side of forward and backward template, to guarantee the sealing of whole device, anti-impervious liquid leaks material;
B) piston rod is set in the fixed frame cinclides, and the axis of piston rod is parallel with fixed frame inner orbit surface;
C) also be provided with one group on front template and dash the material object in advance, it is a needle-valve by handwheel, screw mandrel control, and valve body is directly arranged on the front template, and the charging hole of valve and material runner communicate, and the discharge opening of valve leads to the pre-mesopore that dashes material station flow distribution plate;
D) also be provided with on front template and the pre-exhaust overfolw hole of expecting that mesopore communicates that dashes, the position of exhaust overfolw hole is higher than the position of needle-valve discharge opening, thereby assurance can fully be filled up the flow distribution plate mesopore when dashing material in advance;
E) outer surface up and down in the front and back template is equipped with heater, makes forward and backward template and can be heated together with contacted flow distribution plate, to adapt with temperature of charge.
Dash in the material member pre-, for reducing the wearing and tearing of needle-valve spool, make screw mandrel and spool be separated into two, linked to each other by an adapter sleeve, this adapter sleeve is connected on the screw mandrel, and spool is set in the centre bore of adapter sleeve, and is located by threaded connector.When the operation handwheel drives the screw mandrel rotation, because the conversion of adapter sleeve makes spool produce the rectilinear direction motion, thereby opens or shut valve.Two assemblings, the degree of wear that can look separately during use is keeped in repair, and replaces, and is comparatively convenient.
The runner mesopore of described rear pattern plate can be a straight line, also can become vertical turn or inclination at angle, and this moment, the corner can be designed to spherical transition, to slow down the Flow of Goods and Materials resistance, makes and flows gently, thereby guarantee quality of item.
In order to make the total compactness, the import and the exit of material runner on the template of described front and back directly are provided with on template with material and manage projection or groove and the Screw hole structure that is connected usefulness, can remove other ring flange etc. from like this, make simple in structurely, and have dwindled volume.
The embodiment accompanying drawing is provided below:
Fig. 1 is the utility model structural representation.Among the figure, 1 is fixed frame, 2 push-and-pull activity box, 3 flow distribution plates, 4 piston rods, 5 oil cylinders.
Fig. 2 is the A-A cutaway view of Fig. 1.Among the figure, 6 is front template, 7 heating plates, and 8 screen packs, 9 rear pattern plates, arrow B is represented the Flow of Goods and Materials direction.
Fig. 3 is the vertical view of Fig. 1.Among the figure, 10 is handwheel, 11 screw mandrels, 12 spools, 13 charging holes, 14 discharge openings, 15 exhaust overfolw holes.
Fig. 4 is a needle-valve part enlarged drawing.16 is adapter sleeve among the figure.
When this device operate as normal, three flow distribution plates are arranged in the push-and-pull activity box, promptly one in advance towards the material state, one for just at work, another piece is for complete state to be unloaded.When the need draping, the new flow distribution plate that screen pack is housed is placed in the preparation station, start oil cylinder then, piston promotes activity box, make new flow distribution plate to the pre-material station that dashes, the former pre-flow distribution plate that dashes on material station and the work runner station all moves forward, and the flow distribution plate of preparing to wait to unload on the station is pushed out outside the machine, pushes back moving activity box by manually unloading post-tensioning.Whole draping process only needed for 2 seconds.
Enforcement model machine of the present utility model is on probation in plastics-production, and its performance meets production requirement, good reliability fully.
The utility model can be at quick net exchanging under the stopped status not, because therefore new web plate preheating and fill the material exhaust can guarantee that quality of item is unaffected, and whole device good airproof performance, the ne-leakage phenomenon, and also it is little to have a volume, the characteristics of compact conformation.
