Description
Technical field
This utility model be related to mechanical field and in particular to a kind of for PS foam tandem extruder net-changing device.
Background technology
During existing plastic extrusion, plastic melt, through plastifying for a long time and being heated, will produce decomposition in melt
Residual thing, adds the impurity in raw material, once they enter in extrusion die, will result in flow blockage, and plastic occurs
Defect, so can not normally produce.
In order to filter debris, make pure fused raw material smoothly enter extrusion molding die head, generally in filtering area and will squeeze
Go out setting drainage screen between molding die, for stoping impurity and foreign body from entering among molding die.
Conventional PS foaming tandem extruder, is only provided with net-changing device in first order outlet of extruder, goes out when running into drainage screen
When now abnormal (bore a hole, do not install), the debris in raw material cannot filter, and affect manufacturing schedule and processing quality, cause
Unnecessary waste.
Utility model content

The drawbacks described above leading in art.
A kind of net-changing device of the tandem extruder that foams for PS, including die head, the front end of described die head be provided with front mold plate,
Rear mold plate and net-changing device, described front mold plate and rear mold plate are fixed by connector and are left gap between the two, described
Net-changing device includes filter screen bracket, filter screen body, middle plate, bindiny mechanism, installing plate and cylinder, and described filter screen bracket is provided with screw thread
Hole, described filter screen body is threaded in screw thread in the hole, and one end of filter screen bracket is connected with middle plate, and middle plate is connected with cylinder, institute
State bindiny mechanism and include the connecting rod that is connected on filter screen bracket and the nut threadeded with connecting rod.
Preferably, the wherein side of described filter screen body is provided with two circular grooves, and circular groove is with filter screen body
The heart is symmetrical arranged for the center of circle.
Preferably, described front mold plate and rear mold plate are provided with sealing ring.
Preferably, described filter screen body is generally circular in shape.
Preferably, the side of described screwed hole is provided with the limited step of annular, the outside of limited step and filter screen bracket
Side flushes.
The utility model has the advantage of：This utility model passes through to increase a net-changing device it is achieved that bilayer in die head section
Filter, the impurity in raw material can get effective filtration, residual quantity is little to be reduced and waste it is ensured that manufacturing schedule, in addition, by optimizing
The structure design of net-changing device, so that the replacing of filter screen body is convenient, when blocking, only needs cylinder band electric filter body to go out
Come, then change filter screen body, draping process is simple, efficiently.
