It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other.

In order to reduce the waste of the yarns on the outer sides of the precursor yarn clusters and save the production cost, the inventor designs a single-machine-head double-split cake winding machine to cake the yarns on the outer sides of the precursor yarn clusters to form yarn clusters with reduced quality, save raw materials, reduce environmental pollution and improve economic and social benefits.

The single-machine-head double-split cake winding machine and the cake winding method thereof provided by the invention are described in detail below with reference to the accompanying drawings.

Fig. 1 shows a schematic structural diagram of an embodiment of a single-head double-split pancake winding machine according to the present invention, and referring to fig. 1, the single-head double-split pancake winding machine includes a double-split winding machine head 1, a yarn guide frame 2, a tension adjusting mechanism 3, a cutting mechanism 4 and a controller 5. The double-branch-pulling machine head 1 comprises a first winding position 11 and a second winding position 12 which are arranged side by side, wherein the first winding position 11 is used for winding outside yarns of a yarn group of raw silk, and the second winding position 12 is used for winding inside yarns of the yarn group of raw silk, so that the whole yarn group can be fully utilized, the outside yarn is wound into the yarn group with reduced product quality, the balance of the product quality is ensured, the waste of waste silk and materials is reduced, and the cost is saved.

In the winding process, after the end part of the yarn is manually wound around the yarn guide frame 2 and the tension adjusting mechanism 3 in sequence and then fixed on the first winding position 11 or the second winding position 12, the controller 5 controls the double-dividing-pulling machine head 1 and the cutter mechanism 4 to orderly operate according to a preset program or an operation mode, and the outside yarn with slightly lower quality on the yarn group and the inner yarn with standard quality are respectively wound on the first winding position 11 and the second winding position 12, so that the full utilization of the yarn is realized, and the quality balance of yarn groups formed by winding on each winding position is ensured.

In the single-head double-split draw cake winding process, the controller 5 controls the double-split draw machine head 1 to rotate to meet a first preset condition, then controls the cutting mechanism 4 to cut yarns, and controls the double-split draw machine head 1 to stop running. After the cut yarn end part is manually wound around the yarn guide frame 2 and the tension adjusting mechanism 3 in sequence, the yarn end part is fixed on the first winding position 11 or the second winding position 12, and then the double-split-drawing machine head 1 is restarted to operate through the controller 5. The first preset condition may be that the operation duration or the number of operation turns of the double-split drawing machine head 1 reaches a preset value, or may be that a yarn group of a cake on the double-split drawing machine head 1 meets a preset condition, for example, the thickness of the yarn group reaches a preset thickness value or the weight of the yarn group reaches a preset weight value, etc.

In the embodiment provided by the invention, the single-machine-head double-split cake winding machine further comprises a yarn group detection mechanism 6 in signal connection with the controller 5, wherein the yarn group detection mechanism 6 is used for detecting yarn group signals on the double-split machine head 1 and sending detection results to the controller 5 in real time. The controller 5 controls the orderly operation of the cutting mechanism 4 according to the received detection result of the yarn cluster detecting mechanism 6.

In this embodiment, the first preset condition includes: the detection value of the yarn group detecting mechanism 6 satisfies the second preset condition. For example, the detection value of the yarn group detecting mechanism 6 is larger or smaller than a preset detection value.

In an alternative embodiment, the yarn-cluster detecting mechanism 6 comprises a pressure sensor or a distance sensor for detecting the yarn-cluster weight of the cake on the double-split-draw head 1 or the yarn-cluster diameter of the cake on the double-split-draw head 1, and the second preset condition comprises: the detection value of the pressure sensor is larger than a preset pressure value or the detection value of the distance sensor is smaller than a preset distance value. When the yarn group detecting mechanism 6 includes a pressure sensor, the pressure sensor may be disposed on the double-split head 1 or may be disposed outside the double-split head 1.

In an alternative embodiment, a first weighing sensor is arranged on the first cake station 11, a second weighing sensor is arranged on the second cake station 12, and the first weighing sensor and the second weighing sensor are in signal connection with the controller; the second preset condition includes: the detection value of the first weighing sensor reaches a first preset value or the detection value of the second weighing sensor reaches a second preset value.

In another alternative embodiment, referring to fig. 1, the yarn package detecting mechanism 6 is located on one radial side of the double split head 1. At this time, if the yarn cluster detection mechanism 6 detects a distance signal on the surface of the yarn cluster, that is, when the yarn cluster detection mechanism 6 detects that the distance on the surface of the yarn cluster is smaller than the preset value, the controller 5 determines that the diameter of the yarn cluster reaches the preset diameter according to the detection result, at this time, the controller 5 controls the cutting mechanism 4 to cut the yarn, and then controls the double-split drawing machine head 1 to stop running. If the yarn cluster detection mechanism 6 detects a pressure signal, when the extrusion force of the yarn cluster on the double-split head 1 to the yarn cluster detection mechanism 6 reaches a preset value, the controller 5 can judge that the diameter of the yarn cluster reaches the preset value or the weight of the yarn cluster reaches the preset value according to the detection result, so that the controller 5 controls the cutting mechanism 4 to cut off the yarn and then controls the double-split head 1 to stop running.

For example, as shown in fig. 1, the yarn group detecting mechanism 6 may be located on one side in the horizontal direction of the double-split head 1, for example, between the tension adjusting mechanism 3 and the double-split mechanism 1, or on one side in the vertical direction of the double-split head 1, for example, at a preset interval directly below or above the double-split head 1. It should be noted that the yarn group detecting mechanism 6 is provided with a pressure sensor or a detection end of a distance sensor toward the double-split head 1, regardless of the arrangement with respect to the double-split head 1.

In an alternative embodiment, the first preset condition further includes: the double split head 1 is operated at a preset speed for a preset period of time or the double split head 1 is rotated for a preset number of turns. Because the quantity of the outer yarn with damaged quality on the precursor yarn cluster is relatively uniform, the first preset condition is mainly used for judging whether the outer yarn of the precursor yarn cluster is completely entangled to the first entangling position 11. For example, after the outer yarn of one yarn cake sequentially bypasses the yarn guiding frame 2 and the tension adjusting mechanism 3, the yarn is fixed on the first cake position 11, and the controller 5 starts the double-dividing-pulling machine head 1 to form yarn cakes with reduced cake quality and the like; when the double-split-drawing machine head 1 runs at a preset speed for a preset time period or rotates for a preset number of turns, the controller 5 judges that the outside yarns with damaged quality on the precursor yarn groups are totally wound on the first winding position 11, at the moment, the cutting mechanism 4 is controlled to cut the precursor yarns, the cut yarns are wound on the second winding position 12 after sequentially bypassing the yarn guide frame 2 and the tension adjusting mechanism 3 by manpower, and then the double-split-drawing machine head 1 is started again through the controller 5 to continue winding to form high-quality and uniform yarn groups.

Referring to fig. 1, in the single-head double-split pancake winding machine according to the present invention, the cutting mechanism 4 includes: a first cutting portion 41, a second cutting portion 42, a cutting frame 43, and a power device 44. Wherein, the middle part of the first cutting part 41 and the middle part of the second cutting part 42 are hinged with the cutting frame 43, and the first cutting part 41 and the second cutting part 42 can be meshed; the output end of the power device 44 is in transmission connection with the first cutting part 41, and the input end of the power device 44 is in signal connection with the controller 5.

In an alternative embodiment, the power unit 44 is located on the cutting frame 43. The yarn in the cake is positioned between the first cutting part 41 and the second cutting part 42, and the first cutting part 41 and the second cutting part 42 move towards opposite directions under the drive of the power device 44, so that the yarn is separated after occlusion cutting is completed, and the yarn is cut.

For example, the power plant 44 may employ a cylinder. As shown in fig. 1, the output end of the air cylinder is connected with the end of the first cutting portion 41, when the controller 5 receives the detection signal of the yarn cluster detection mechanism 6 and judges that the detection value meets the second preset condition, the controller 5 starts the air cylinder to control the air cylinder to extend out of the preset stroke, so that the first cutting portion 41 and the second cutting portion 42 are fully meshed, the yarn cutting operation is completed, and then the air cylinder is controlled to retract to drive the first cutting portion 41 to restore to the original position.

In an alternative embodiment, the tensioning mechanism 3 comprises a support 31 and a number of tension bars 32, the yarn being wound around the number of tension bars 32 in sequence during the winding process. Wherein, be provided with a plurality of adjustment tank on support 31, tension bar 32 is located the adjustment tank, and a plurality of tension bar 32 interval stagger arrangement realizes the tension adjustment to the yarn through adjusting the position of every tension bar 32 in the respective adjustment tank.

Illustratively, the position of each tension rod 32 is adjusted according to the production requirements so that the spacing between each tension rod 32 meets the production requirements, ensuring that the yarn is able to smoothly shuttle after passing each tension rod 32. A yarn passes through two tension bars 32 mounted in parallel, and the yarn passes between the two tension bars 32 in an S-shape, so that the yarn transitions from random jump to smooth so as to be fixed in position. Actual production proves that the distance between the two tension rods is 4 cm-5 cm, the actual use effect is best at present, and the length of the tension rods can be set to be 15cm.

Referring to fig. 1, the tension adjusting mechanism 3 further includes a plurality of tension pulleys 33, and the yarn sequentially passes around the plurality of tension pulleys 33 during the winding process. By sequentially bypassing the yarn around the plurality of tensioning wheels 33, the tension of the yarn during the winding process is obtained, thereby judging whether the position of the tension rod 32 needs to be adjusted.

In an alternative embodiment, the tensioning wheels 33 may also be arranged side by side in the axial direction, each two of which are on the same axis, corresponding to the first cake station 11 and the second cake station 12 arranged side by side.

In the embodiment shown in fig. 1, four sets of tensioning wheels 33 are provided, each set comprising two. The tensioning control box of the tensioning wheel 33 can be controlled in linkage with the double-split-head 1. The tension range of the tensioning wheels 33 can be automatically adjusted according to the production process so as to ensure the yarn tension balance and balance the tension and the resistance of the yarn when the yarn shuttles between the tensioning wheels 33.

Illustratively, each tensioning wheel 33 may also be provided with a counterweight damping structure, for example, by adding or subtracting a counterweight to the yarn to form a tension value between the tensioning wheels 33, by lever principle and brake pad function, ensuring tensioning of the yarn during shuttling between the tensioning wheels 33.

In order to ensure the smoothness of the cake of the yarn, at least two yarn guiding holes or yarn guiding grooves are arranged on the yarn guiding frame 2; during the winding process, the yarn passes through the yarn guide hole or the yarn guide groove. Illustratively, the yarn guide 2 may be made of a stainless steel thin tube, its shape angle and a semicircular structure design. According to the actual yarn from the previous stage to-be-wound yarn winding to the yarn guiding frame 2, the yarn irregularly jumps and is filtered, so that the yarn tends to be stable, and the winding stability of the yarn winding in the next stage is ensured.

In an alternative embodiment, the dual-split head 1 further comprises a driving motor, and the controller 5 effectively controls the start-stop and the running speed of the dual-split head 1 by controlling the start-stop of the driving motor.

The invention also provides a cake winding method of the single-machine-head double-split cake winding machine, which is realized by the single-machine-head double-split cake winding machine.

Fig. 2 shows a real-time flow chart of one embodiment of the cake method of the present invention, with reference to fig. 2, comprising the steps of:

step S110: the outside yarns of the precursor yarn groups are wound on a first cake winding position 11 of the double-split-drawing machine head 1 after sequentially bypassing the yarn guide frame 2 and the tension adjusting mechanism 3, and the double-split-drawing machine head 1 is controlled to run by the controller 5;

step S120: after the double-split drawing machine head 1 runs for a preset time period or a preset number of turns, the controller 5 controls the cutting mechanism 4 to cut yarns and controls the double-split drawing machine head 1 to stop running;

step S140: when the yarn group signal on the second winding position 12 or the first winding position 11 is detected to meet the second preset condition, the controller 5 controls the cutting mechanism 4 to cut the yarn.
