Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of spinneret with replaceable spinneret.

For achieving the above object, the utility model provides following technical scheme: a kind of spinneret, comprises plate body, described plate body one side is provided with charging face, also comprise some installing holes through plate body, in each installing hole, all split is connected with spinneret, in described spinneret, is provided with spinneret orifice.

Between spinneret and installing hole, adopt split setting, be that spinneret can directly remove in installing hole, in the time that needs normally use, spinneret can directly be installed in installing hole, tow can directly be squeezed out from spinneret orifice, and now the shape of spinneret of the shape facility of tow completely thus time determines; Accordingly, in the time that customer demand changes, we can be by directly spinneret being removed in installing hole, and being installed in installing hole with the spinneret of another shape of spinneret, multiplex thereby perfection realizes a plate.

Preferably, between described spinneret and installing hole, adopt tight fit.

Tight fit can effectively promote the installation stability between spinneret and installing hole, prevent in handling process, spinneret surprisingly drops out in installing hole, in the time that needs are dismantled, because installing hole is directly through plate body, dismounting personnel can be by slightly knocking spinneret, and spinneret can be pounded out very like a cork in installing hole.

Preferably, between described spinneret and installing hole, adopt and be threaded.

The mode being threaded, has taken into account the stability of detachability and connection, and operating personnel can directly realize it by positive and negative rotation spinneret and fix and disassembling function, very convenient.

Preferably, the end of described spinneret is provided with the groove that inserts and drive described spinneret rotation for peripheral hardware instrument.

Groove is similar to the slot on screw nut, for can better be by extraneous extracting tool, therefore groove is set in spinneret end, in the time of dismounting, extracting tool, the cutter head of for example straight screwdriver is directly inserted in groove, then drive spinneret to be rotated, can easily complete dismantlement work, otherwise, complete stable installment work, certainly equally also consider that tow is in the time extruding, its direction of extruding power is the axial direction along spinneret, it is larger that it extrudes power, frictional force between spinneret lateral wall and installing hole inner hole wall is corresponding stronger, its fixing stability is higher.

Preferably, described installing hole is that the large end of bellmouth and this installing hole is positioned at charging face one side, and described spinneret lateral wall is the conical surface, and described spinneret is fit in installing hole from charging face one side.

In installation process, first, the small end of this spinneret is inserted into the large end place of installing hole, subsequently, the contact area of the lateral wall of spinneret and the hole wall of installing hole becomes greatly gradually, until both are completely bonded to each other, in said process, the small end of spinneret is inserted into the large end of installing hole, can effectively promote the grafting accuracy of spinneret; In use procedure, because the small end of spinneret is to be fit into installing hole from charging face one side, the large end that is installing hole is the side towards charging hole, and the direction of extruding of topknot is towards opposite side from charging face one side, now topknot to extrude power larger, extruding force between the conical surface of spinneret and the hole wall of installing hole is larger, and stability in use is higher.

Preferably, described spinneret is made up of magnetic material.

Because the material of plate body is generally iron material, and the spinneret that magnetic material is made can with plate body generation magnetic attraction, ensure use or handling process in, spinneret separates with installing hole.

In sum, the beneficial effect that the utility model in contrast to prior art is: be connected by the split between spinneret and spinneret orifice, along with client's requirement, only need to change the spinneret on plate body, and do not need to change whole plate body, realize a plate multiplex, significantly reduced placement space, and reduced the production cost of tow.
