Description

Winding equipment for cable processing

Technical Field

The utility model relates to the technical field of cable core processing, in particular to winding equipment for cable processing.

Background

Cables are typically composed of a twist of several wires or groups of wires. In the cable processing, to ensure that the cable core can be tightly twisted, a winding operation is generally performed by means of a winding device, i.e. winding yarn around the surface of the cable core to tighten the cable core.

When the current winding equipment is designed, a mounting shaft for mounting yarn groups is arranged in a shell of the winding equipment, the yarn groups are unwound by the mounting shaft through autorotation, and the unwound yarn is driven to be wound on the surface of a cable core to be transmitted by driving the shell to rotate. Since the housing rotates at a high speed to generate severe vibration, the service life of the device is shortened to avoid abrasion of accelerating parts due to vibration, and the rotation speed of the housing is limited, and since the yarn wound around the cable core is single-stranded, even if the housing rotates at a highest speed, the number of turns of the yarn wound around the cable core per unit time is limited, and therefore, in order to obtain a high-density winding effect, it is generally required that the cable core is conveyed at a low speed, but this severely reduces the processing efficiency.

Referring to fig. 1 to 2, a winding apparatus for cable processing capable of unwinding at least two yarn groups and winding at least two yarns unwound to a cable core to prevent the cable core from being loosened according to a preferred embodiment of the present utility model will be described in detail below. The cable core is provided with at least two fixed positions, each fixed position is used for correspondingly fixing the end part of one yarn, and two adjacent fixed positions are separated by a preset distance.

The winding device for cable processing comprises a workbench 10 and at least one yarn bundling body 20, wherein the yarn bundling body 20 comprises a shell 21. The housing 21 has a mounting cavity 2101, a mounting port 2102 and an outlet 2103, the mounting port 2102 and the outlet 2103 being disposed opposite each other and communicating with the mounting cavity 2101. The housing 21 can be penetrated by the cable core in a manner of being clamped with the mounting port 2102 and the protruding port 2103. The housing 21 is provided on the table 10, and the housing 21 can be driven to rotate about an axis of the cable core inserted into the housing 21 as a rotation center.

Referring to fig. 2 to 4, the yarn bundling body 20 further includes at least two mounting shafts 22, the mounting shafts 22 are rotatably mounted in the mounting cavities 2101, the rotation direction of the mounting shafts 22 is the same as the unwinding direction of the yarn groups, and the mounting shafts 22 are used for mounting one yarn group. The mounting shaft 22 unwinds the yarn package by spinning.

The housing 21 has at least two thread fixing structures 211, and the thread fixing structures 211 are located on the outer periphery of the mounting shaft 22 and do not interfere with the yarn groups provided on the mounting shaft 22. The thread fixing structure 211 is used for limiting the trend of the yarn which is arranged on the installation shaft 22 and is guided to the cable core by unreeling the yarn group. The casing 21 can be driven to rotate so as to drive at least two strands of yarns led out by unreeling the yarn groups by at least two mounting shafts 22 through at least two yarn fixing structures 211 to rotate and wind on the surface of the cable core to be transmitted, thereby carrying out high-density winding on the cable core. Compared with the prior art, the yarn bundling main body 20 can keep high-efficiency winding under the condition of being far smaller than the operation limit, realize high-efficiency work while reducing the operation requirement, and can avoid severe vibration of equipment, extend the service life and reduce noise.

Preferably, the thread fixing structure 211 is embodied as a thread guiding wheel, which is arranged to be rotatable. When the yarn, which is led out by unreeling the yarn ball mounted on the mounting shaft 22, is driven by the housing 21 to wind the cable core, the yarn passing wheel is driven by the yarn to rotate, so that friction force when the yarn is driven is reduced.

It should be noted that at least two of the mounting shafts 22 can rotate at different speeds, so that the yarn groups mounted on the mounting shafts 22 can be conveyed at a predetermined tension, and the condition that a plurality of yarn groups are loosened and a part of the yarns are tightened due to the size difference in the conveying process is prevented, and the overall winding quality is affected.

Referring to fig. 2 to 3, the winding apparatus for cable processing further includes at least one rotation member 30, and the rotation member 30 is disposed in the same number as the bundle yarn body 20.

Preferably, two yarn bundling bodies 20 are provided, and the two yarn bundling bodies 20 are disposed opposite to each other in a form corresponding to the mounting hole 2102 of the housing 21. The yarn groups mounted on the mounting shafts 22 are all located at one side of the fixing position of the cable core, at this time, the yarn groups on the mounting shafts 22 in one housing 21 are directly guided to the cable core through the corresponding fixing structures 211, and the yarn groups on the mounting shafts 22 in the other housing 21 are conducted through the fixing structures 211 and are guided to the cable core through the mounting openings 2102 of the two housings 21.

Preferably, the two shells 21 can be driven to rotate reversely at a constant speed, and at this time, the two shells 21 can drive the mounting shafts 22 in the respective mounting cavities 2101 to unwind the yarn groups so as to lead at least four strands of the yarn to be wound on the surface of the cable core in a crossing manner, so that the tight yarn binding of the cable core is realized.

It should be noted that the thread fixing structure 211 is capable of directing the yarn led out by the rotational unwinding of the yarn package by the mounting shaft 22. In this way, the yarn unwound from the yarn package can be conveyed along a predetermined route regardless of the size of the yarn package, so that the yarn passing through the mounting openings 2102 of the two housings 21 is required to be excessively deviated from the center of the mounting openings 2102 in the initial stage of unwinding, and friction is generated between the yarn and the housings 21, resulting in damage to the yarn and influencing winding quality.

Referring to fig. 2, 4 and 5, the winding apparatus for cable processing further comprises a set of conveying assemblies 40, the conveying assemblies 40 include at least two guide wheels 41, the guide wheels 41 are rotatably mounted in the mounting cavities 2101 of the housing 21 at the fixed position far from the cable core, and the number of the guide wheels 41 is consistent with the number of the mounting shafts 22 in the housing 21.

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

The yarn guided to the fixing structure 211 by being unwound in correspondence with each of the mounting shafts 22 in the housing 21 can be conducted by the guide wheels 41 through the through holes 2201 of the mounting shafts 22 and the mounting ports 2102 of the two housings 21 and wound on the surface of the cable core in such a manner that the ends of the yarn are fixed at one of the fixing positions of the cable core, the guide wheels 41 being used for directionally conducting the yarn, defining a partial trend of the yarn, i.e., the yarn can pass through the mounting shafts 22 and the mounting ports 2102 of the two housings 21 in a fixed posture, so as to reduce the design requirements of the apparatus.

Referring to fig. 3 to 5, the winding apparatus for cable processing further includes a coupling shaft 50, the coupling shaft 50 is inserted into the mounting ports 2102 of the two housings 21 and penetrates the mounting shaft 22 inserted into the mounting ports 2102, and the coupling shaft 50 is provided to be rotatable together with the housing 21 to which the guide wheel 41 is mounted. The coupling shaft 50 has a passage 501, and the mounting cavities 2101 of the two housings 21 communicate through the passage 501. The channel 501 has a size that is larger than the size of the cable core. In this way, the yarn conducted by the guide wheel 41 can move inside the channel 501, preventing it from being contaminated during the winding process.

The transfer assembly 40 further comprises at least two sets of traction wheels 42, said traction wheels 42 being arranged so as to be able to guide the yarn transferred via the guide wheels 41 towards the cable core, each set of traction wheels 42 being parallel to the axial direction of the corresponding guide wheel 41.

Preferably, two traction wheels 42 are provided, wherein one traction wheel 42 is located between the corresponding guide wheel 41 and the other traction wheel 42, and during the process of guiding the yarn conveyed by the guide wheel 41 to the cable core by each traction wheel 42, the yarn conveyed by the guide wheel 41 is conveyed by the corresponding traction wheel 42 in a manner of being attached to one traction wheel 42 near the axle center side of the linkage axle 50, and the yarn conveyed by the traction wheel 42 is conveyed by the other traction wheel 42 in a manner of being attached to the other traction wheel 42 far from the axle center side of the linkage axle 50. In the process, the yarn is driven by both of the traction wheels 42 at a predetermined tension to ensure that the yarn is tightly wound around the cable core.

It should be noted that the two traction wheels 42 of each group can separate the yarn from the cable core and the inner wall of the linkage shaft 50 in the channel 501 while conducting the yarn, so as to prevent the yarn from being worn due to friction between the portion of the yarn not wound on the cable core and the inner wall of the linkage shaft 50, and affect the yarn binding strength.
