Description
Technical field
Textile technology field is the utility model is related to, more particularly to a kind of yarn pretension adjusting apparatus.
Background technology
In fabrication processes, the tension force of yarn needs to carry out pretension, causes yarn slippage in order to avoid unclamping.Yarn pretension is adjusted
Engagement positions mutually twine the contact wheel connect, in addition to adjustable shelf, expansion link, foundation frame, governor motion with yarn including its periphery, contact
Wheel is installed in rotation on adjustable shelf one end, and expansion link is fixed on the adjustable shelf other end, expansion link be installed on foundation frame and by
Governor motion control carries out axially adjustable.
However, the governor motion of yarn pretension adjusting apparatus does not often accomplish accurate, stable regulation, cause yarn
Tension force is difficult to reach suitable degree.
Utility model content
The purpose of this utility model is to provide a kind of yarn pretension adjusting apparatus so that the tension force of yarn can reach conjunction
Suitable degree, is conveniently adjusted.
What the purpose of this utility model was realized in：A kind of yarn pretension adjusting apparatus, including its periphery and yarn
The contact wheel connect, in addition to adjustable shelf, expansion link, foundation frame, governor motion are mutually twined, the contact wheel is installed in rotation on work
Moving frame one end, the expansion link are fixed on the adjustable shelf other end, and the expansion link is installed on foundation frame and modulated mechanism control
System progress is axially adjustable, and the governor motion includes adjustment gear, regulation handle, support wheel, adjusting screw, the adjustment gear
It is installed in rotation on support wheel on foundation frame, the expansion link is provided be meshed with adjustment gear, its length side
To axially consistent guiding rack, the adjustment gear and support wheel are respectively at expansion link two opposite sides, institute with expansion link
Support wheel periphery is stated against expansion link, the regulation handle is fixedly mounted on the gear shaft of adjustment gear and for adjusting adjustment
The torque of gear, the threaded portion of the adjusting screw, which is worn, to be connected on foundation frame, and the threaded portion of the adjusting screw is against stretching
Contracting boom end.
Compared with prior art, the beneficial effects of the utility model are：It is easy to be adjusted the tensioning degree of yarn；
When adjusting yarn tension, regulation handle is moved so that adjustment gear rotation, adjustment gear is by being oriented to rack drives expansion link
Axial stretching displacement is carried out, support wheel also rotates simultaneously, to offset pressure of the adjustment gear for expansion link, to ensure expansion link
The linearity of axial stretching displacement is carried out, due to driving expansion link to carry out flexible displacement by the way of rack pinion,
Therefore, the flexible shifting movement of expansion link has good stability, after the position adjustment in place of expansion link, can use and adjust
Section screw withstands expansion link, so as to lock the position of expansion link, so that it is determined that the tensioning degree of yarn.
Brief description of the drawings
Fig. 1 is total configuration diagram of the present utility model.
Wherein, 1 yarn, 2 contact wheels, 3 adjustable shelfs, 4 expansion links, 4a guiding racks, 5 adjustment gears, 6 regulation handles, 7
Support wheel, 8 foundation frames, 9 adjusting screws.
Embodiment
As shown in figure 1, a kind of yarn pretension adjusting apparatus, including its periphery twine the contact wheel 2 connect with the phase of yarn 1, also
Including adjustable shelf 3, expansion link 4, foundation frame 8, governor motion, contact wheel 2 is installed in rotation on the one end of adjustable shelf 3, expansion link 4
The other end of adjustable shelf 3 is fixed on, expansion link 4 is installed on foundation frame 8 and modulated mechanism controls carry out axially adjustable, regulation machine
Structure includes adjustment gear 5, regulation handle 6, support wheel 7, adjusting screw 9, adjusts gear 5 and support wheel 7 is rotatably mounted
On foundation frame 8, it is axially consistent with expansion link 4 that expansion link 4 is provided with, its length direction being meshed with adjustment gear 5
Be oriented to rack 4a, adjust gear 5 and support wheel 7 and be respectively at the two opposite sides of expansion link 4, the periphery of support wheel 7 against expansion link 4,
Regulation handle 6 is fixedly mounted on the gear shaft of adjustment gear 5 and the torque of gear 5, the spiral shell of adjusting screw 9 is adjusted for adjusting
Line portion, which is worn, to be connected on foundation frame 8, and the threaded portion of adjusting screw 9 is against the end of expansion link 4.
When adjusting 1 tension force of yarn, regulation handle 6 is moved so that adjustment gear 5 rotates, and adjustment gear 5 is by being oriented to tooth
Bar 4a drives expansion link 4 to carry out axial stretching displacement, and support wheel 7 also rotates simultaneously, to offset adjustment gear 5 for expansion link 4
Pressure, with ensure expansion link 4 carry out axial stretching displacement linearity, due to being driven by the way of rack pinion
Expansion link 4 carries out flexible displacement, and therefore, the flexible shifting movement of expansion link 4 has good stability, in the position of expansion link 4
Put after being adjusted in place, can be withstood expansion link 4 with adjusting screw 9, so as to lock the position of expansion link 4, so that it is determined that yarn
The tensioning degree of line 1.
The utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can is special to some of which technology
Sign makes some and replaces and deform, and these are replaced and deformed in the scope of protection of the utility model.
