As Fig. 1, Fig. 2, shown in Figure 3, it comprises mechanical fixation mechanism, feedback unit and electric part test the speed; Wherein:
1) mechanical fixation mechanism: an end of first swing arm 5 and second swing arm 6 is hinged, and concrete articulated manner is to be connected by a bolt 19, cap nut 3, nut 2, wherein bolt 19 heads down, cap nut 3 is in the top, nut 2 is in the middle level.
The other end of first swing arm 5 is fixed on the rove bobbin cradle 18 with fixture 25, and an end of first gripper shoe 22 is positioned at the below of first swing arm, 5 other ends, is fixed on rove bobbin cradle 18 with fixture 25 equally, and what fixture 25 designed is shaped as
It is comprehensive applying rove bobbin cradle 18.It is in order to fix first gripper shoe 22 and second swing arm 6, and the three is fixed on the rove bobbin cradle 18 by bolt 19.Wherein fixture 25 is in the superiors, and second swing arm 6 is in the middle level, and first gripper shoe 22 is in orlop.
The other end of first gripper shoe 22 is connected with second gripper shoe 23, the part that first gripper shoe 22 is connected with second gripper shoe 23 all has a rectangular hole, bolt 19 is fixed two gripper shoes by two rectangle holes, because the existence of hole, can be according to the fixing height of sphere 24 in the size adjustment bottom of rove tube 21.
The other end of second gripper shoe 23 and bottom fixedly sphere 24 are connected, and bottom fixedly sphere 24 withstands on the bottom centre of rove tube 21; In order to avoid driving shaft 16 produces unnecessary rocking when reclining rove 20.
The other end of second swing arm 6 is equipped with fixed axis 15, and the top on fixed axis 15 tops is fixed on the end of second swing arm 6 by hexagonal (hexagon)nut 13.
Be positioned on the fixed axis 15 of second swing arm, 6 lower ends and first gear 12 and driving shaft 16 be installed successively, driving shaft 16 lower end bolting.Driving shaft 16 can rotate around fixed axis 15, and driving shaft 16 is by totally two bearings 14,17 realization rotations up and down.
At second swing arm, 6 middle parts motor 1 is installed, is stretched out and on the motor shaft of second swing arm, 6 lower ends second gear, 11, the first gears 12 are installed and second gear 11 is meshing with each other; At the middle part of first swing arm sleeve 8 is installed, sleeve 8 is to be enclosed within on the hexagon socket head cap screw 7, because the existence of sleeve 8 can reduce the friction of spring 9 and hexagon socket head cap screw 7.
At an end of second swing arm 6 and two screws 10 are installed above the swing arm between the motor 1, an end of spring 9 is fixed on the screw 10, and the other end is walked around sleeve 8 and is fixed on another screw 10; It is that rove tube 21 can be changed and can fit the tightly reason of rove tube 21 of driving shaft 16 easily that spring 9 shrinks the elastic-restoring force that produces.When driving shaft 16 passes through mid point by the external force swing, with hexagon socket head cap screw 7 is fulcrum, spring 9 is owing to the elongation of self produces elastic shrinkage, one side of first swing arm, 5 deflections shrinks the effect that produces elastic-restoring force because of being subjected to spring 9, so just make rove tube 21 and the driving shaft 16 that is fixed in first swing arm 5 tightly recline, finish rove 20 unwindings.In like manner, when driving shaft 16 is flapped toward the opposing party by external force, just can finish the more operation of creeling tube 21.
2) feedback unit that tests the speed: form by main encoder with from encoder 26, the drafter rear roller that its main encoder position is installed in wool spinning frame rotates the tip of the axis, is installed in the below of second gear 11 from encoder 26 positions;

The material of surperficial one deck of described driving shaft 16 is by acrylonitrile-butadiene rubber, and has the rhombus twill, and is less near the diameter of two end portions, bigger near the diameter of mid portion.(the specific design size should design voluntarily according to the size of the back rove barrel shape of reeling).The rhombus twill can reduce the damage to fiber, increases the frictional force between driving shaft and the rove simultaneously.
The concrete operation principle of the present invention:
A positive unwinding mechanism is installed on each rove bobbin cradle 18 of wool spinning frame, and in the process of the high rabbit hair spun yarn of spinning, when starting the wool spinning frame switch, the rear roller turning cylinder begins to rotate, and motor 1 switch also starts immediately.By the main encoder that is installed in rear roller turning cylinder end, measure the linear resonance surface velocity of rear roller, after being sent to PLC27 with the form of the signal of telecommunication, again through the PLC27 computing, obtain the frequency converter 28 of corresponding analog quantity input motor, frequency converter 28 is controlled motors 1 running speed, thereby further reaches the purpose of the rotating speed of control driving shaft 16.When motor 1 entry into service, feed back the linear resonance surface velocity of rear roller once more to PLC27 from encoder 26, the linear velocity that compares both again by the PLC27 computing, utilize frequency converter 28 constantly to adjust motor 1 running speed again, tracking is consistent with unwinding layer yam surface linear velocity up to the linear resonance surface velocity of rear roller, finally reaches the purpose of both linear velocity unanimities.In order to reach this purpose, motor 1 running is through 11 outputs of second gear, and then 16 rotations of control driving shaft, rove tube 21 applying driving shafts 16, and the mode of dependence friction realizes the unwinding of rove 20.
Because rove 20 has winding angle (to be made as α in the process of reeling, the winding angle of each layer rove of rove tube is α) existence, under the mode that relies on frictional drive, also along the unwinding of winding angle direction, the linear resonance surface velocity of driving shaft 16 (is made as V when then designing during rove 20 unwindings
1) linear resonance surface velocity that should be slightly larger than rove 20 (is made as V
2), linear velocity between the two has following relation:
V
1＝V
2cosa
By known winding angle size, frequency converter 28 automatic fine tunings reach the linear resonance surface velocity and the consistent purpose of unwinding layer yam surface linear velocity of rear roller with the rotating speed of control driving shaft 16.The design of driving shaft 16 is for the rove tube 21 of fitting in all directions, and the diameter that promptly is designed to close two end portions is less, near the bigger mode (the specific design size should design according to the size of rove tube 21 shapes) of diameter of mid portion.Its principle is the characteristics according to column shape cross-winding rove tube 21 self, the rove 20 that is edge, rove tube 21 both sides can unroll after finishing a circle coiling, rove 20 is for the radial pressure of internal layer rove 20 in the middle part of comparing, the radial pressure of 20 pairs of internal layer rove 20 of edge rove is less than normal, therefore the rove tube 21 after reeling presents the edge diameter characteristics bigger than middle part diameter (naked eyes are difficult to identification, and having only rove tube 21 to be subjected to certain extruding could show).Driving shaft 16 outermost layers are made up of nitrile rubber and are had the rhombus twill, can reduce the damage to fiber, increase the frictional force between driving shaft 16 and the rove 20 simultaneously.
The two-end-point of spring 9 is fixed on the screw 10, and spring 9 is walked around hexagon socket head cap screw 7, and it is that rove tube 21 can be changed and can fit the tightly reason of rove tube 21 of driving shaft 16 easily that spring 9 shrinks the elastic-restoring force that produces.When driving shaft 16 passes through mid point by the external force swing, with hexagon socket head cap screw 7 is fulcrum, spring 9 is owing to the elongation of self produces elastic shrinkage, one side of first swing arm, 5 deflections shrinks the effect that produces elastic-restoring force because of being subjected to spring 9, so just make rove tube 21 and the driving shaft 16 that is fixed in first swing arm 5 tightly recline, finish rove 20 unwindings.In like manner, when driving shaft 16 is flapped toward the opposing party by external force, just can finish the more operation of creeling tube 21.
