Description

Technical Field

[0001] The invention relates to the technical field of cable core processing, in particular to a yarn binding device for cable processing and a working method thereof. Background Art

[0002] Cables are typically made up of several or several groups of twisted conductors. During cable processing, to ensure the cable core is tightly twisted, a binding operation is usually performed with the help of a yarn binding device. This involves wrapping yarn around the surface of the cable core to tighten the cable core.

[0003] Among them, some of the current yarn binding equipment is in use. A yarn ball is installed in each of the two oppositely arranged pots. The two yarn balls rotate to unwind and lead out two strands of yarn. The ends of the two strands of yarn are fixed to the cable core. By driving the two pots to rotate in opposite directions and drive the two strands of yarn to be cross-wound around the surface of the cable core.

[0004] The cable core is conveyed at a predetermined speed. The faster the rotation of the pan, the closer the distance between two adjacent yarn intersections on the cable core surface, and the tighter the cable core is tied. Since high-speed rotation of the pan generates severe vibration, there is an upper limit to the pan's rotation speed to avoid vibration that accelerates part wear and affects the service life of the equipment. In addition, the yarn wound around the cable core in a single direction is a single strand. Therefore, to obtain better yarn binding quality, the pan is required to rotate quickly, and the speed at which the cable core is conveyed is controlled within a predetermined range to keep the spacing between the yarn intersections within a predetermined size. However, the length of the yarn tied per unit time is still very limited, and the processing efficiency is very low. Summary of the Invention

Therefore, the above terms should not be understood as limiting the present invention.

[0032] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0033] refer to Figures 1 to 2A yarn binding device for cable processing according to a preferred embodiment of the present invention will be described in detail below. The device is capable of unwinding at least three yarn balls and winding the unwinding at least three strands of yarn around a cable core to prevent the cable core from loosening. The cable core has at least three fixed positions, each of which corresponds to a yarn end, and adjacent two fixed positions are separated by a predetermined distance.

[0034] The yarn binding device for cable processing includes a workbench 10 and a yarn binding body 20. The yarn binding body 20 includes two housings 21. The housings 21 have an installation cavity 2101, an installation opening 2102, and an extension opening 2103. The installation opening 2102 and the extension opening 2103 are arranged opposite each other and are both connected to the installation cavity 2101. The housings 21 can be penetrated by the cable core by being engaged with the installation opening 2102 and the extension opening 2103. The two housings 21 are arranged on the workbench 10 with the installation openings 2102 facing each other. The housings 21 can be driven to rotate about the axis of the cable core inserted into the housings 21, and the two housings 21 rotate in opposite directions.

[0035] refer to Figures 2 to 4 The yarn binding body 20 further includes at least three mounting shafts 22. At least two of the mounting shafts 22 are rotatably mounted in the mounting cavity 2101 of one housing 21, and at least one of the mounting shafts 22 is rotatably mounted in the mounting cavity 2101 of the other housing 21. The mounting shafts 22 are used to mount a yarn ball, and their rotational directions are the same as the unwinding direction of the corresponding yarn ball. The mounting shafts 22 unwind the yarn ball by rotating.

[0036] The yarn binding body 20 includes at least three thread-fixing structures 23, the number of which matches the number of the mounting shafts 22. The thread-fixing structures 23 are disposed within the mounting cavity 2101, positioned around the corresponding mounting shaft 22 and not interfering with the yarn balls mounted on the mounting shafts 22. The thread-fixing structures 23 are used to control the direction of the yarns being unwound from the yarn balls mounted on the mounting shafts 22 and directed toward the cable core.

[0037] The two housings 21 can be driven to rotate in opposite directions, and at least three of the yarn strands unwound from the at least three mounting shafts 22 are driven via the at least three wire-fixing structures 23 to cross-wrap the at least three strands of yarn onto the surface of the driven cable core, thereby performing high-density yarn binding on the cable core. Compared to existing technologies, the rotation speed of the yarn-binding body 20 is reduced while maintaining efficient yarn binding, achieving efficient operation while reducing operating requirements. This also prevents severe vibration, extends the service life, and reduces noise.

[0038] Preferably, the thread fixing structure 23 is implemented as a thread wheel, which is configured to rotate. When the yarn ball mounted on the at least three mounting shafts 22 is unwound and the yarn is driven by the two housings 21 to be cross-wound around the cable core, the thread wheel is driven by the yarn to rotate, thereby reducing friction when the yarn is transmitted.

[0039] Preferably, the yarn balls installed on at least three of the installation shafts 22 are all located on one side of the fixed position of the cable core. In this case, the yarn ball on the installation shaft 22 in one of the housings 21 is directly guided to the cable core via the corresponding wire fixing structure 23, while the yarn ball on the installation shaft 22 in the other housing 21 is guided to the cable core via the wire fixing structure 23 through the installation openings 2102 of the two housings 21. In this way, the unwound yarns of at least three yarn balls have the same direction, ensuring that at least three strands of yarn can be wound around the surface of the cable core at a predetermined tension, thereby preventing some of the yarns from becoming loose and affecting the quality of the binding.

[0040] Preferably, four mounting shafts 22 are provided, and every two mounting shafts 22 are correspondingly installed on one shell 21. At this time, the yarn balls installed on the four mounting shafts 22 are unwound to cross-wrap the four strands of yarn around the surface of the cable core, thereby tightly binding the cable core.

[0041] It is worth mentioning that the two adjacent mounting shafts 22 can rotate at different speeds so that the yarn balls mounted on the mounting shafts 22 can be transported with a predetermined tension, and prevent the situation where some of the yarns are loose and some are tight during the transport process due to size differences among the multiple yarn balls, thereby affecting the overall yarn binding quality.

[0042] refer to Figures 2 to 3 The yarn binding device for cable processing also includes a driving component 30, and the driving component 30 includes two first driving components 31. The two first driving components 31 are correspondingly installed on the two shells 21, and the two shells 21 can be driven by the two first driving components 31 to rotate in opposite directions.

[0043] The mounting shaft 22 has a mounting portion 221 and a belt rotating portion 222. The mounting portion 221 is rotatably mounted in the mounting cavity 2101 and extends out of the mounting cavity 2101 through the mounting opening 2102 to form the belt rotating portion 222. The driving member 30 further includes at least three second driving components 32, each of which is connected to the belt rotating portion 222 of the mounting shaft 22. The second driving components 32 are configured to drive the mounting shaft 22 to rotate.

[0044] Preferably, the second driving assembly 32 can drive the installation shaft 22 to rotate at a variable speed, and the yarn guided out of the yarn ball unwound by the installation shaft 22 is transmitted at a predetermined tension by regulating the rotation speed of the installation shaft 22 .

[0045] Preferably, the first rotation driving assembly 31 and the second rotation driving assembly 32 are both implemented as belt transmission devices.

[0046] It is worth mentioning that the thread fixing structure 23 can directional conduct the yarn released by the yarn ball unwinding through the mounting shaft 22. In this way, regardless of the size of the yarn ball, the unwound yarn can be conveyed along a predetermined route, effectively preventing the yarn ball from being too large, causing the yarn passing through the mounting openings 2102 of the two housings 21 to deviate too far from the center of the mounting openings 2102 during the initial unwinding process, thereby causing the yarn to rub against the housing 21, resulting in yarn damage and affecting the yarn binding quality.

[0047] refer to Figure 2 、 Figure 4 and Figure 5 The yarn binding equipment for cable processing also includes a group of transmission components 40, and the transmission component 40 includes at least one guide wheel 41. The guide wheel 41 is rotatably installed in the installation cavity 2101 of the shell 21 at the fixed position away from the cable core. The number of the guide wheels 41 is consistent with the number of the installation shafts 22 in the corresponding shell 21.

[0048] The installation shaft 22 has a through hole 2201 . The installation portion 221 and the rotating portion 222 form the through hole 2201 . The through hole 2201 is coaxial with the installation opening 2102 . The size of the through hole 2201 is larger than that of the cable core.

[0049] The yarn that is unwound corresponding to each of the mounting shafts 22 in the shell 21 and guided to the fixed wire structure 23 can be conducted by the guide wheel 41 and pass through the through hole 2201 of the mounting shaft 22 and the mounting openings 2102 of the two shells 21 and be wound around the surface of the cable core in the form of the end of the yarn being fixed at a fixed position on the cable core. The guide wheel 41 is used to directional conduct the yarn and limit the partial direction of the yarn, that is, the yarn can pass through the mounting shaft 22 and the mounting openings 2102 of the two shells 21 in a fixed posture to reduce the design requirements of the equipment.

[0050] refer to Figures 3 to 5The cable processing yarn binding device further includes a linkage shaft 50, which is plugged into the mounting openings 2102 of the two housings 21 and extends through the mounting shaft 22 plugged into the mounting openings 2102. The linkage shaft 50 is configured to rotate together with the housing 21 on which the guide wheel 41 is mounted. The linkage shaft 50 has a channel 501, through which the mounting cavities 2101 of the two housings 21 are connected. The size of the channel 501 is larger than the size of the cable core. In this way, the yarn guided by the guide wheel 41 can move within the channel 501, thereby preventing the yarn from being contaminated during the binding process.

[0051] The transmission assembly 40 further includes at least one set of traction wheels 42. The number of sets of traction wheels 42 is the same as the number of guide wheels 41. The traction wheels 42 are configured to guide the yarns transmitted by the guide wheels 41 toward the cable core. Each set of traction wheels 42 is parallel to the axial direction of the corresponding guide wheel 41. The traction wheels 42 are rotatably mounted on the linkage shaft 50. At this time, the traction wheels 42 can rotate together with the housing 21 on which the guide wheels 41 are mounted via the linkage shaft 50, so that the yarns guided out of the corresponding housing 21 can be rotatably wound around the surface of the cable core.

[0052] Preferably, the traction wheel 42 is rotatably mounted on the channel 501. In this case, the traction wheel 42 can not only conduct the yarn, but also does not need to occupy external space, thereby reducing the overall volume.

[0053] Preferably, each set of traction wheels 42 is provided with two, one of which is located between the corresponding guide wheel 41 and the other traction wheel 42. When each set of traction wheels 42 guides the yarn conveyed via the guide wheels 41 to the cable core, the yarn conveyed via the guide wheels 41 is conveyed by the corresponding traction wheel 42 in a manner such that it adheres to the side of the traction wheel 42 closer to the axis of the linkage shaft 50, while the yarn conveyed via the traction wheels 42 is conveyed by the other traction wheel 42 in a manner such that it adheres to the side of the other traction wheel 42 farther from the axis of the linkage shaft 50. During this process, the yarn is transmitted by the two traction wheels 42 at a predetermined tension to ensure that the yarn is tightly wound around the cable core.

[0054] It is worth mentioning that the two traction wheels 42 in each group can separate the yarn from the cable core in the channel 501 and the inner wall of the connecting shaft 50 while transmitting the yarn, so as to prevent the part of the yarn not wound around the cable core from rubbing against the cable core and the inner wall of the connecting shaft 50 and causing wear, thereby affecting the yarn binding strength.

[0055] A working method of a yarn binding device for cable processing is now proposed, comprising the following steps:

[0056] A cable core is inserted into the protruding openings 2103 of the two shells 21 and passes through the two shells 21;

[0057] The mounting shafts 22 in the mounting cavities 2101 of the two housings 21 are driven to rotate in the same direction as the unwinding direction of the yarn balls disposed on the mounting shafts 22. The ends of the yarns unwound from the yarn balls on each mounting shaft 22 are mounted at a fixed position on the cable core, and the yarns are guided to the cable core via the fixing structure 23.

[0058] The shells 21 are driven to rotate in opposite directions, and the two shells 21 drive at least three installation shafts 22 to unwind at least three strands of yarn through at least three fixed wire structures 23, and cross-wrap the at least three strands of yarn on the surface of the cable core, thereby performing high-density yarn binding on the cable core.

[0059] Preferably, the working method of the yarn binding device for cable processing comprises the following steps:

[0060] The two adjacent installation shafts 22 can be driven to rotate at different speeds to ensure that the yarn unwound by each installation shaft 22 is delivered at a predetermined tension.

[0061] Preferably, the working method of the yarn binding device for cable processing comprises the following steps:

[0062] The cable core is held in its fixed position on one side of the yarn ball mounted on the mounting shaft 22 and passes through the two housings 21;

[0063] When the housing 21 at the fixed position away from the cable core is in operation, the yarn unwinding from the yarn ball by the installation shaft 22 in the installation cavity 2101 thereof is conducted by the yarn fixing structure 23 and guided to the guide wheel 41. The yarn guided by the guide wheel 41 passes through the through hole 2201 of the installation shaft 22 and the two installation openings 2102 of the housing 21.

[0064] The guide wheel 41 guides the yarn to the traction wheel 42 correspondingly installed on the linkage shaft 50, and the traction wheel 42 guides the cable core. The shell 21 on which the guide wheel 41 is installed drives the traction wheel 42 to rotate through the linkage shaft 50, so that the yarn transmitted by the traction wheel 42 is wound around the surface of the cable core.
