Description
Technical field
The present invention relates to the guidance pin for paraffin body, the waxing attachment including guiding pin in this way and for manufacturing winch spool
Son and the weaving loom including such waxing attachment.
Background technique
For certain process in textile industry, particularly with warp knit and weft knitting, thread friction must be reduced to obtain
Preferably mobile sliding capability.
It is a kind of reduce thread friction mode be when yarn is wound to winding bobbin to yarn waxing.It is being used in
Such as in the case of the waxing attachment on bobbin-winding machine or open-end spinning frame, yarn contacts paraffin body end face is moved and in mobile yarn warp
Minimal amount paraffin is continuously collected when crossing paraffin body.These paraffin particles are sufficient to then in the weaving process pass through yarn
Yarn introduction member surface lubrication, so that thread wear tinily moves.
In order to obtain paraffin body friction uniform as far as possible in such waxing attachment, usually make paraffin body in paraffin body
Heart longitudinal axis slowly rotates, and at the same time, mobile yarn slightly acts on paraffin body end face.
For this purpose, paraffin body is by axially adjustable but be nonrotatably mounted tO can be on driven holding rod surface and in normality
It is lower to be pressed on stroke limiter or backstop by spring part, limit the operating position of paraffin body.The holding of this waxing attachment
The different embodiments of the driving device of bar are put into use.
But because paraffin body only slides on holding rod, therefore paraffin body can not be reliably fixed.Paraffin body may shake
Dynamic, sliding is even overturn on holding rod, therefore has too many or very little paraffin to be coated onto the danger on yarn.In addition, depositing
It is described when no longer sliding past paraffin body end face in yarn but only passing through the least favorable of regional area or marginal zone
The danger that yarn incision paraffin body and a fritter paraffin body are cut away by yarn.In addition, it is undesirable abrasion cause weaving loom or
Station it is dirty.
WO2008/128601A1 discloses a kind of waxing dress for manufacturing the station of the weaving loom of cross winding bobbin
It sets.In order to guarantee the perfect guidance paraffin body in the driving support rod of waxing attachment, especially the mounting hole of paraffin body is transversal
The cross section of face and the supporting area of driving support rod must be mutually matched.In practice it means that especially with regard to paraffin body mounting hole
Only a certain paraffin body can be used on any specific waxing attachment to this design for cross section.
Summary of the invention
Therefore, the present invention relates to a kind of guidance pin for paraffin body, which can be mounted on guidance with being adjusted axially
On pin, which has mounting hole in the central longitudinal axis region of paraffin body.
The characteristics of guidance pin proposed, which is the guidance pin, has following mechanism, the mechanism design in guidance pin free ending tool
First position is maintained at by retentivity at it and guarantees that paraffin physical efficiency is fixed on guidance pin, the mechanism is also designed
The mechanism is moved to from first position at the power described when the power for acting on the mechanism overcomes the retentivity
The second position, so that paraffin body can be upper to guidance pin by sliding sleeve or be removed on pin from guiding.
Due to this design of guidance pin, paraffin body can not only be sold smooth sliding sleeve to guidance as before, also rolled up
It is sold around guidance is fixed on solid and reliablely in the process.Therefore, paraffin body will not both shake, and will not slide, therefore guarantee
The yarn waxing of continuous uniform and prevent paraffin body segment cut away and the weaving of the following manufacture winding bobbin
Machine it is undesirable dirty.
Because in order to overcome the retentivity, (mechanism is maintained at first position fixing paraffin body by the retentivity
Guidance pin on) and need to only apply one exceed retentivity power, therefore paraffin body can smoothly and tool-lessly looked after
On employee's sliding sleeve of the weaving loom or remove.It means that since paraffin body sliding sleeve itself is loaded onto, therefore retentivity is overcome and institute
It states mechanism and is moved to the second position, it can paraffin body on sliding sleeve on the second position.Because applying dauer effect to the mechanism
Retentivity, therefore cause directly to exert a force to paraffin body, which is fixed on paraffin body on guidance pin, but also keep can people for paraffin body
Work is mobile and adjusts.Under normality, paraffin body is maintained on guidance pin, until paraffin body is used up, but can also be from maintaining part or attached
It is connected to removal paraffin body on the guidance pin of maintaining part.That is as long as paraffin body to be placed in guidance pin upper and therefore at least partly
Also it is placed in the mechanism for guiding pin, paraffin body just exerts a force to the mechanism, which exerts a force and fix to paraffin body again
Paraffin body.

Ball is pressed outward and positions, so that the peripheral radius about guidance pin is projected radially outwardly from guidance pin.When paraffin body sliding sleeve fills
When upper, the power bigger than retentivity is applied to the ball.Thus the ball is moved to the second position, described on the second position
Ball is pressed inwardly and does not project radially outwardly about the peripheral radius of guidance pin from guidance pin, or compared in first position
It is projected radially outwardly less about guidance pin peripheral radius from guidance pin.It is upper and extremely that the paraffin body that sliding sleeve gets on is supported on guidance pin
Small part is located on ball.Because the retentivity continuingly acts on ball towards first position, therefore the ball is then needed for waxing
To paraffin body continuous applying force on paraffin body position.It is contemplated that two, the ball of three or more can be arranged in frame of the present invention.
Alternatively, the mechanism is formed by least two-piece type clamping element.
Retentivity acts on the clamping element, so that clamping element is oppressed the first position for separating and being loaded into clamping element.Such as
Fruit paraffin body then exerts a force to clamping element, the power causes clamping element to be entered by pressing with overcoming retentivity by sliding sleeve to guidance pin
The second position and paraffin body are with can crossing clamping element on sliding sleeve to guidance pin.Because in the state of being installed on guidance pin above
Paraffin body be at least partly placed on clamping element always, therefore paraffin body is reliably and firmly held in place by retentivity, should
Retentivity acts on clamping element and compressing clamping element separates.
In another alternate design, the mechanism is formed by least two clamping jaws.
Such design equally ensure that guidance sell with can crossing clamping jaw by sliding sleeve for paraffin body, thus clamping jaw is moved
To the second position of clamping jaw.The retentivity so acts on clamping jaw, the clamping jaw radially stress, as long as and paraffin body be located at and draw
On guide pin and thus on clamping jaw, paraffin body just on its specified position be clamped keep.
In another alternate design, the mechanism is formed by cylindricality apical cap portion.
It is maintained on the first position in apical cap portion with the apical cap portion for selling bigger outer diameter than guidance by the retentivity
And it towards piston is forced rearwardly into the second position by sliding dress paraffin body.Retentivity of the acting in opposition in apical cap portion continues
The apical cap portion is forced to first position and thus adjusts the paraffin body.
It, can be in the present invention in order to enhance this effect and bigger retentivity can be applied by the apical cap portion to paraffin body
Expect that apical cap portion can be widened and guide pin in cone in frame, so that the apical cap portion is moved toward first position in apical cap portion
When the inclined-plane sold by the guidance widened.
In an expedients, which can be generated by least one compressed spring.
Compressed spring is the substitution optional way for generating the economic and not many change of continuous retentivity.Such as it can also be with
Using cylindrical compression spring.
But retentivity for example can also be generated with pneumatic mode in the literal scope of the present invention.Because generating holding
The mode of power is not critical to the present invention, therefore is contemplated that all substitution optional ways being proposed that, and compressed spring is only
It is a particularly advantageous embodiment.
Another aspect of the present invention be related to it is a kind of for manufacturing the waxing attachment of the station of the weaving loom of winding bobbin,
With the guidance pin for paraffin body, which can be mounted on the guidance pin with being adjusted axially, and the paraffin body is in paraffin
