Fig. 2 is the left view schematic diagram of the damping lever jack described in Fig. 1.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to Fig. 1-2, a kind of damping lever jack for textile machine, including bottom plate 1, helical spring 5, open tubular column 3,
Sleeve 7, frame 4 and lever jack 9, the bottom plate 1 are symmetrically set with a pair, and the top of bottom plate 1 is fixedly connected with open tubular column
3, open tubular column 3 is internally provided with the frame 4 for extending the top of open tubular column 3, and the bottom of the frame 4 inside open tubular column 3 leads to
Helical spring 5 is crossed with the downside inwall of open tubular column 3 to be connected, integrally formed with annular protrusion 6 among the surface of the frame 4,
The top of annular protrusion 6 is provided with the sleeve 7 run through by the activity of frame 4, and the sleeve 7 is in the shape of lower ending opening, the sky
Stem 3 is located at the inside of sleeve 7, and the side wall of the sleeve 7 offers screwed hole, puller bolt 8 is provided with screwed hole, is located at
The top of the frame 4 of left and right sides is rotatably connected to lever jack 9, and the front-rear side walls of the frame 4 are connected through the hinge have pendulum respectively
Dynamic connecting rod 14, the bottom of swinging connecting rod 14 are connected through the hinge the bar 12 that is slidably connected, side before and after the top of the sleeve 7
Wall has been respectively fixedly connected with fixed plate 14, and the bar 12 that is slidably connected passes through fixed plate 14, described the another of bar 12 that be slidably connected
End is connected through the hinge and has L-type pressure ram 13, the fixation on the downside of the surface of L-type pressure ram 13 with being fixedly connected in fixed plate 14
Bar 15 is connected by hinge, and the upper end of the L-type pressure ram 13 is fixedly connected with stripper plate 16, and stripper plate 16 is close to frame
4 side wall fixed bonding has slipmat 17;When yarn derived from textile machine due to tractive force it is uneven and make lever jack 9 by
During vibration, due to the effect of helical spring 5, the effect of damping, buffering is played to the lever jack in frame 4, so as to effectively
Reduce due to tractive force it is excessive and produce broken string situation, and when frame 4 suddenly by larger vibration when, cause frame 4
Oscillating region becomes big, now the swing for moving down drive swinging connecting rod 11 of frame 4, so that the bar 12 that is slidably connected is slided
It is dynamic, therefore surround L-type pressure ram 13 and rotated with the hinged place of fix bar 15 for the center of circle, now slipmat 17 is to frame 4
Extruded, therefore avoid the further Oscillation Amplitude of frame 4, so that the yarn on lever jack 9 is avoided due to guide
The shaking amplitude of bar 9 is excessive and makes the situation of yarn unrest line or broken string, due to the effect of helical spring 5 make machine make frame 4 by
Gradually reset, therefore while cushioning buffer effect is played to lever jack 9, it also avoid the excessive situation of amplitude, therefore this reality
There is good practical function with new, and by unclamping or tightening puller bolt 8, helical spring 5 can be adjusted to machine
Elastic thrust under the poised state of frame 4, so as to as needed be increased the initial vibration resistance of lever jack 9, from
And excessively slight vibration will not have an impact to lever jack 9.
The bottom of the bottom plate 1 is provided with self-locking universal caster wheel 2, is easy to move the present embodiment.
The lever jack 9 is connected with the contact position of frame 4 by deep groove ball bearing, and reduction lever jack 9 rubs with frame 4
Wear consumption.
The surface of the lever jack 9 is uniformly fixedly connected with toroidal membrane 10, reduces the situation that yarn is wound.
The material of the slipmat 17 is usual silicone rubber.
The surface of the slipmat 17 offers friction lines, improves the frictional behaviour of slipmat 17.
Operation principle of the present utility model is:Yarn is placed on lever jack 9, because the movement of yarn is so that lever jack
9 are rotated, when yarn derived from textile machine makes lever jack 9 vibrated because tractive force is uneven, due to spiral
The effect of spring 5, the effect of damping, buffering is played to the lever jack in frame 4, so as to effectively reduce due to tractive force
Situation that is excessive and producing broken string, and when frame 4 suddenly by larger vibration when, cause the oscillating region of frame 4 to become big, this
When frame 4 move down drive swinging connecting rod 11 swing so that the bar 12 that is slidably connected enters line slip, therefore extrude L-type
Bar 13 surrounds to be rotated with the hinged place of fix bar 15 for the center of circle, and now slipmat 17 is extruded frame 4, therefore is avoided
The further Oscillation Amplitude of frame 4, so that the yarn on lever jack 9 is avoided because the shaking amplitude of lever jack 9 is excessive
And make the situation of yarn unrest line or broken string, because the effect of helical spring 5 makes machine frame 4 is gradually resetted, therefore to leading
While yarn bar 9 plays cushioning buffer effect, the excessive situation of amplitude is it also avoid, therefore the utility model has well in fact
With effect, and by unclamping or tightening puller bolt 8, helical spring 5 can be adjusted to the bullet under the poised state of frame 4
Property thrust, so as to as needed be increased the initial vibration resistance of lever jack 9, so as to which excessively slight vibration will not
Lever jack 9 is had an impact.
