Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below so that those skilled in the art can better understand the advantages and features of the present invention, and thus the scope of the present invention will be more clearly defined. The embodiments described herein are only a few embodiments of the present invention, rather than all embodiments, and all other embodiments that can be derived by one of ordinary skill in the art without inventive faculty based on the embodiments described herein are intended to fall within the scope of the present invention.
Examples
The invention adopts a discontinuous tooth-shaped belt transmission mode to realize alternate transmission of the drafting units of the A-color yarns and the drafting units of the B-color yarns.
Take color unit a as an example:
as shown in figure 1, English letters a-g are the core transmission device of the invention, a motor is transmitted to a driving toothed belt wheel a through a speed reducer, and the toothed belt wheel transmits a driving toothed belt b to rotate anticlockwise.
The inner side and the outer side of the toothed belt are both distributed with teeth, the inner side is distributed with continuous teeth, and the teeth on the outer side of the driving toothed belt b are distributed discontinuously and are divided into a toothed area I and a non-toothed area II. The inner side and the outer side of the gap bridge toothed belt c are both distributed with continuous teeth.
(1) The A color roving enters a drafting unit
When the driving toothed belt wheel a rotates clockwise to drive the driving toothed belt b to rotate clockwise, and a toothed area I of the driving toothed belt wheel is meshed with outer teeth of the gap bridge toothed belt c, the gap bridge toothed belt is driven to rotate anticlockwise, inner teeth (not marked in the figure) of the driving toothed belt wheel drive the gap bridge toothed belt wheel d to rotate anticlockwise, a transmission belt wheel e is coaxially arranged with the gap bridge toothed belt wheel, so that the transmission belt f also rotates anticlockwise to drive a middle roller transmission wheel g to rotate anticlockwise, and at the moment, the A-color roving enters the drafting unit through a horn mouth of the middle roller.
(2) Process for stopping A-color roving from entering drafting unit
When the toothless area II reaches the bridge toothed belt c, the transmission function cannot be achieved due to the toothless of the bridge toothed belt in the area, the middle roller transmission wheel g cannot rotate clockwise, the middle roller stops active drafting rotation, and the color A roving stops entering the bell mouth of the middle roller for drafting under the drafting function.
(3) B color unit: the motion time of the B color yarn drafting unit is just opposite to that of the A color, and the principle is the same.
Namely yarn A: enter-stop; at this time, the yarn B: stop-enter. The two are alternately carried out
Specifically speaking: when the A color roving enters the middle roller drafting unit according to the step (1), the motion of the B color yarn is just opposite to that of the A color yarn, the A color yarn does not enter the drafting unit, namely, the toothless area II reaches the gap bridge toothed belt c ', the gap bridge toothed belt has no teeth in the area, the transmission function cannot be achieved, the rear roller driving wheel g' cannot rotate clockwise, the active drafting rotation is stopped, and the B color roving stops entering the rear roller bell mouth for drafting due to the drafting function.
When the driving toothed belt wheel a ' rotates clockwise to drive the driving toothed belt B ' to rotate clockwise, and a toothed area I thereof is meshed with the outer side teeth of the gap bridge toothed belt c ', the gap bridge toothed belt is driven to rotate anticlockwise, the inner side teeth drive the gap bridge toothed belt wheel d ' to rotate anticlockwise, and a transmission belt wheel e ' is coaxially arranged with the gap bridge toothed belt wheel, so that the transmission belt f ' also rotates anticlockwise to drive the rear roller transmission wheel g ' to rotate anticlockwise, and at the moment, the B-color roving enters the drafting unit through the rear roller bell mouth.
(4) Time interval adjustment
The running and stopping, i.e. the pause time, can be varied by varying the number of teeth of the discontinuous toothed belt, the longer the toothless zone, the longer the pause time, the shorter the movement time, and vice versa, according to the different lengths of the yarns of the A color and the B color in the finished yarn, when the intermittent pause or the running time of the A unit and the B unit is adjusted, the number of teeth on the toothed belt needs to be adjusted, for example, the color a is long, the color B is short, the running time of the unit a is longer than that of the unit a, the active toothed belt B of the unit a has more toothed areas and less non-toothed areas, on the contrary, the active toothed belt B' of the unit B has less toothed areas and more non-toothed areas, or the unit a can have more and less intermittent toothed belts, the colors a appear to alternate in length and length on the resultant yarn, and similarly, the B unit, so that various combinations of the colors a and B in length can be produced by the permutation and combination of the number of teeth on the toothed belt of A, B units.
Therefore, the invention can change the interval time in a stepless way theoretically and is convenient to adjust.
(5) The present invention is also suitable for tricolor yarns or combinations thereof.
(6) Tooth mounting combination of toothed belt
The teeth of the toothed belt are inserted by a loop, as shown in figure 4, each movable tooth 01 is inserted in the middle between the upper and lower bottom plates 02 of the outer toothed belt and fixed by a positioning screw 04, a reinforcing rib 03 is arranged between the upper and lower bottom plates of the toothed belt to increase the toughness of the toothed belt, and the inner side of the toothed belt is provided with continuous teeth 05 which are formed at one time and used for being meshed with the teeth of the upper and lower toothed belt wheels in figure 1 to play a role in transmission.
