Description
Technical field
The utility model is related to on-line period field more particularly to a kind of extruder on-line period mechanisms.
Background technology
In extruder process of manufacture, need to carry out sample inspection to the molten material real time sample in extruder
It surveys, traditional sampling mode is to extract molten material from the extrusion of extruder, and this sampling mode is generally required to interrupt and be squeezed
Go out the normal operation of machine and be sampled operation, production efficiency is caused to reduce.
Utility model content
In order to solve the above technical problems, the utility model provides, a kind of mechanism is simple, and the extruder of contaminated material is not online
Sampling mechanism, including handpiece body, runner, rotating device, elastic pressuring clamping device and fixing seal device；The rotating device includes
Axis pin, rotary shaft, rotating handles and locking nut with holes, for the rotary sleeve in axis pin with holes, the rotating handles are logical
Locking nut is crossed with the rotating handles to be connected；The elastic pressuring clamping device includes stretching screw, dish-shaped gasket and plain cushion, described
Stretching screw head is set with two panels plain cushion, and saucer washer is provided among plain cushion, for stretching screw to be fixed on handpiece body
On, the stretching screw is connected with pin bolt with holes.The fixing seal device includes axis gland, filler and end cover nut,
The end cover nut is connected by filler with axis gland, for rotation axis seal to be fixed on handpiece body；On the handpiece body
Thief hole is offered, the orifice diameter of the thief hole is equal with the orifice diameter of axis pin with holes and orifice position is opposite
It answers；The runner passes through the handpiece body.
In said program, the rotating device further includes a limiting plate, and the limiting plate is fixed on the rotary shaft, for limiting
The rotation angle of rotary shaft processed.
In said program, the axis pin with holes is taper pin with split pin hole axis.
The beneficial effects of the utility model are compared with prior art：The on-line period device is mounted on squeezing for extruder
Go out excessive body or die portion, it, can be by the molten material in extruder by taking under the normal open state of extruder
Sample hole, which is taken out, carries out sample detection, it can be achieved that fast sampling, not the characteristics of contaminated material.

Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Figure 1, a kind of extruder on-line period mechanism, including handpiece body 2, runner 1, rotating device, elastic compression
Device and fixing seal device.Rotating device includes axis pin 11, rotary shaft 6, rotating handles 8 and locking nut 7 with holes, rotary shaft
6 are sleeved in axis pin 11 with holes, and axis pin 11 with holes is taper pin with split pin hole axis, and when on-line period is sealed by the conical surface.Rotation
Handle 8 is connected by locking nut 7 with rotary shaft 6.Elastic pressuring clamping device includes stretching screw 12, dish-shaped gasket 14 and plain cushion
13；12 head of stretching screw is set with two panels plain cushion 13, and saucer washer 14 is provided among two panels plain cushion 13, for that will tense spiral shell
Nail 12 is fixed on handpiece body 2；Stretching screw 12 is connected with 11 bolt of axis pin with holes.Fixing seal device includes axis gland 4, fills out
The sealing of rotary shaft 6 is fixed on handpiece body 2 by material 10 and end cover nut 9, axis gland 4 by filler 10 and end cover nut 9.Head
Cylindrical thief hole 3 is offered on body 2, the diameter of thief hole 3 is greater than or equal to the orifice diameter and the two of axis pin 11 with holes
Orifice position it is corresponding, runner 1 pass through handpiece body 2.
In order to limit the rotation angle of rotary shaft 6, a limiting plate 5 is installed in rotary shaft 6, under the action of limiting plate 5,
Rotary shaft 6 can only rotation in 90 degree, when sampling, rotating handles 8 are rotated down 90 degree, aperture and the thief hole 3 of axis pin 11 with holes
Orifice position it is corresponding, molten material in handpiece body runner 1 is flowed out by the aperture of thief hole 3 and axis pin with holes 11,
It samples, is carried out with handpiece body 2 by the conical surface of taper pin with split pin hole axis 11 when on-line period close under normal boot-strap state to realize
Envelope ensures the aperture outflow of all molten material through hole axis pins 11；Under not sampling state, rotating handles 8 rotate up 90
The non-orifice position of degree, axis pin 11 with holes is directed at thief hole 3, so that the lower end of thief hole 3 is in sealing state, to avoid melting
Shape material flows out.
Above example is only to illustrate the technological thought of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is every according to the utility model proposes technological thought, any change is made on the basis of technical solution, each falls within this reality
With in novel protected range.
