On ring plate 52 fitted with the magnetic patch 51 in corresponding second hole 34, using magnetic material attraction by depression bar with it is corresponding
Magnetic patch 51 is connected, and consolidates and is arranged in corresponding mounting groove.
The width of ring plate 52 is more than the thickness of fixed block 30, is set because two mounting grooves extend through fixed block 30, fixed
The thickness of block 30 is length of the mounting groove on depression bar axial direction, that is to say, that the width of ring plate 52 is being pressed more than mounting groove
Length on bar axial direction, such structure setting ensure that the end of depression bar attracts each other with corresponding magnetic patch 51 all the time, protect
Demonstrate,prove the stability of depression bar.
Preferred connection between depression bar and fixed block 30 is realized by ring plate 52 and magnetic patch 51 in the present embodiment, depression bar
Material preferably use stainless steel material, it is therefore desirable to install ring plate 52 additional, ring plate 52 can be set in depression bar end, can also
Depression bar end is processed, makes the wedge pressure boom end of ring plate 52, ring plate 52 selects metal material, such as ring plate made of iron
52。
Certainly, in actual production, other connected modes can also be used between depression bar and fixed block 30, such as directly insert
It is located on fixed block 30, or using mode connects for screw etc..The magnetic preferably used in the present embodiment attracts that depression bar can be easy to
Dismounting and replacing, easy-to-use and stability are good.
As shown in Figure 1 and Figure 4, it is preferable that when corresponding to two depression bars are located in respectively in mounting groove, the first depression bar 41
The air line distance of axial line to the center line of fixed block 30 is less than the axial line of the second depression bar 42 to the straight line of the center line of fixed block 30
Distance.
Here the center line of fixed block 30 refers to center line of the fixed block 30 on the conveying direction of yarn 80, in other words
Say, be that the axial line of the first depression bar 41 is more than the axle center of the second depression bar 42 to the air line distance to the opening of the first mounting groove 31
Line is to the air line distance of the opening of the second mounting groove 32, namely two depression bars are easy to yarn 80 passing through not in same level plane
The conveying track of serpentine is presented during two depression bars, is advantageous to the realization of back-pressure effect.
As shown in Figures 1 to 4, it is preferable that offer " U " breach for accommodating tension rail 20 on two fixed blocks 30 respectively
35, each " U " breach 35 is set through corresponding fixed block 30, and the opening direction of " U " breach 35 and the first mounting groove 31
Opening direction is opposite.
" U " breach 35, which runs through the corresponding setting of fixed block 30, to be easy to fabricate, and is realized when fixed block 30 is arranged on tension rail
When on 20, two depression bars are between warp beam and tension rail 20.The opening direction of preferred U " breach and the first mounting groove 31 herein
Opening direction is opposite, i.e., the opening of U " breach is advantageous to the resistance to overturning of fixed block 30 towards the another side of fixed block 30
Holding.
Preferred yarn 80 is to be conveyed in the horizontal direction by two depression bars and tension rail 20 in the present embodiment, further
The opening on ground, preferably the first mounting groove 31 and the second mounting groove 32 is set upward, is easy to two depression bars loading corresponding install
Groove, and the opening of U " breach is then set down.
In view of yarn 80 passes through the second depression bar 42, the first depression bar 41 and tension rail 20 successively after being unreeled by warp beam 10,
Therefore the first mounting groove 31 is between the second mounting groove 32 and U " breach 35, and the afterbody 312 of the first mounting groove 31 is to lean on
What nearly U " breach 35 was set, namely head 311 bends extension towards U " breach 35 and forms afterbody 312, such structure setting has
Beneficial to the stability for keeping fixed block 30 and whole balancer.
Further, balancer also includes equal with two fixed blocks, 30 one-to-one two stator 60, each stator 60
The opening of correspondingly " U " breach 35 is covered in, the both sides of " U " breach 35 are provided through two bolts 71, and each bolt 71 both passes through
Corresponding stator 60 is simultaneously arranged with nut 72.
Specifically, when fixed block 30 is arranged on tension rail 20, when upper, tension rail 20 was embedded in " U " breach 35 and by solid
Stator 60, bolt 71 and nut 72 are fixed, and wherein fixed block 30 is worn with being offered respectively on stator 60 for bolt 71
The through hole crossed.It is easy to dismount whole balancer using such connected mode, beneficial to maintenance and changes.
Wherein, multiple pads are additionally provided between stator 60 and nut 72（Not shown in figure）, be advantageous to nut 72
Stator 60 is stably mounted on fixed block 30, keeps good stability.
It is noted that tricot machine is mostly that multilayer yarn is woven into cloth when weaving, every layer of yarn is by corresponding
Let-off mechanism is conveyed, and above-mentioned balancer is simply installed on one of let-off mechanism.Further, since tricot machine volume compared with
Greatly, usually You Duotao operating mechanisms（One production line such as i.e. corresponding let-off mechanism, knitting mechanism）Transported on tricot machine
Make, the size of tricot machine is different, and the quantity of real work mechanism is also different, therefore the quantity of the balancer on tricot machine needs basis
Actual demand is selected.
Balancer is arranged on the warp let-off by the tricot machine let-off mechanism of this improvement by the cooperation of stator 60 and fixed block 30
In mechanism, yarn 80 improves the conveying stability of yarn 80, avoids yarn 80 at a high speed by being acted on during two depression bars by back-pressure
Broken under state, hence it is evident that improve product quality and production efficiency, practicality is good.
Described herein is only preferred embodiment of the present utility model, but the scope of protection of the utility model is not
It is confined to this.The utility model those skilled in the art is to the modification of described specific embodiment progress or supplement or adopts
Replaced, all should be covered by within the scope of protection of the utility model with similar mode.
