When the inner cylinder 14 needs to be closed to clamp the wool tops, the two sliding blocks 22 positioned in different semi-cylinders of the inner cylinder 14 gradually contact and clamp the middle wool top 28, and after the inner cylinder 14 is completely closed, the two sliding blocks 22 are tightly matched and clamp the wool top 28 under the action of the spring 23, and meanwhile, the clamping force is not too large.
FIG. 6 is a schematic view of the twisting unit; with the rotation of the base wheel 7, the No. 1 twisting unit 29 firstly enters the clamping plate 4, the universal ball 11 on the No. 1 twisting unit is extruded by the clamping plate 4 to force the outer cylinder 12 to be closed, and the outer cylinder 12 presses the inner cylinder 14 to be closed through the action of the guide wheel 15; the wool tops 28 are clamped by the clamping device when the inner cylinder 14 is closed, the No. 1 twisting unit 29 enters the clamping plate but is not in contact with the shifting pin 5, so that the inner cylinder 14 is only closed and does not rotate, and the wool tops 28 in the twisting unit are clamped and do not move; after the No. 1 twisting unit 30 contacts with the poking pin 5, the poking pin 5 moves along the spiral groove 26, so that the inner cylinder 14 generates a rotating force which pushes the long shaft 20 to break through the limitation of the poking rod 21 and the ratchet wheel 19 to generate a rotating motion relative to the outer cylinder 12; wool top 28 also rotates with inner cylinder 14 of No. 2 twisting unit 30, and the wool top clamped in No. 1 twisting unit 29 does not rotate, so that twisting motion is generated between the two twisting units; after the twisting unit 31 No. 3 is moved out of the clamping plate 4, the inner cylinder 14 is opened again under the action of the torsion spring 24, and the wool tops 28 are conveyed to the next link along with the feeding device 6.
The device adopts 'retreating type' twisting, namely, the wool tops are conveyed forwards and twisted afterwards, so that the loosening and untwisting are avoided; as the wool top 28 does not generate relative friction with the mechanism in the whole process, but utilizes the rotation twisting of the wool top, the flexibility of the rabbit hair is not influenced, and meanwhile, the efficiency of the twisting device is ensured by the continuous circulating work of a plurality of twisting units.
It can be seen that the invention realizes twisting by using the relative motion of a plurality of twisting units; the twisting units are uniformly arranged in a circumference manner, rotate around the shaft and sequentially and circularly pass through the twisting area; the twisting unit has an inner cylinder and an outer cylinder composite structure, and both the inner cylinder and the outer cylinder can be opened and closed in a half-cylinder mode; the twisting unit is in an open state in the non-twisting area, the twisting unit is closed when entering the twisting area, and the rabbit hair strip is clamped by the inner cylinder and moves along with the twisting unit; the inner barrel and the outer barrel of the twisting unit entering the twisting area are kept relatively static, when the subsequent twisting unit also enters the twisting area and is closed to clamp rabbit hair strips, the inner barrel and the outer barrel of the twisting unit which enter the twisting unit rotate relatively, and the hair strips between the two twisting units rotate along with the movement of the twisting unit, so that twisting is realized; after the twisting unit leaves the twisting area, the inner cylinder and the outer cylinder are opened, and the rabbit hair strips which finish twisting leave the twisting unit and enter the next procedure; the twisting unit which does circular motion continuously enters and leaves the twisting area to continuously twist the rabbit hair strips; the quantitative and controllable twisting can be realized by adjusting the distance of the twisting unit and the number of rotating circles.
In the invention, the twisting number of the wool top can be determined by the spiral angle of the spiral groove, and the spiral angle can be artificially manufactured according to the requirement, so that the active, flexible and quantitative twisting can be realized.
Compared with the prior art, the lossless twisting and quantitative twisting device provided by the invention simulates the twisting action of hands, clamps the end head of the wool top to rotate in one direction, flexibly twists the rabbit wool top, and ensures the quality of the wool top while twisting efficiently because the wool top does not have any sliding friction with the device in the twisting process.
Meanwhile, the invention adopts 'retrogressive' twisting, namely, the wool tops are conveyed forwards and twisted afterwards, so as to ensure that the wool tops are not untwisted or loosened.
In a word, the rabbit hair strip twisting mechanism is simple in principle, reasonable in function, ingenious in structure and stable in performance, and effectively solves the problem of rabbit hair strip twisting.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
