Description

Technical Field

[0001] The invention relates to the technical field of cable production, in particular to a cable bracket for cable production. Background Art

[0002] On the wire and cable processing production line, when the wire is transported directly from one processing equipment to another, the transportation distance is sometimes long, resulting in low wire transportation efficiency. During the transportation process, the outer sheath of the cable is easily damaged, making the cable unusable. There is a certain distance between the equipment, so a bracket is needed to support the cable to facilitate the transportation of the cable.

[0003] For example, the Chinese patent with the publication number "CN220222988U" discloses "a cable bracket for cable production", whose main structure includes a bottom plate, on which multiple pairs of guide mechanisms are arranged, the guide mechanisms include a column and a circular ring fixed on the column, multiple threaded through holes are sequentially recessed on the outer circumference of the circular ring, a first screw is threadedly connected to the threaded through hole, one end of the first screw arranged in the circular ring is rotatably connected to a movable plate, a pair of connecting plates are symmetrically fixed on the end face of the movable plate away from the first screw, a pair of connecting plates are rotatably connected to the end faces facing each other with a rotating shaft, a pressure wheel is fixedly sleeved on the rotating shaft, a limiting rod is fixed on one end of the connecting plate facing the first screw, the limiting rod passes through the circular ring and extends to the outside of the circular ring, a rotating handle is fixed on one end of the first screw arranged outside the circular ring, and the column is arranged on the bottom plate. The cable bracket for cable production separates and guides multiple cables through multiple pairs of guide mechanisms, thereby avoiding wear between multiple cables and improving the production quality of cables.

[0004] However, in actual use, the pressure wheel located below needs to bear the gravity from the cable. Since the cable is in a long-distance hanging state, the mass of the cable at this distance is relatively large, and the gravity formed by this mass will be completely transmitted to the pressure wheel located below. The torque resistance of the pressure wheel during rotation will increase with the pressure, resulting in excessive resistance when the pressure wheel rotates, which is likely to cause relative friction between the pressure wheel and the cable body. Once relative friction occurs between the two, due to the relatively large gravity of the cable, the relative friction force formed will also be relatively large, which is likely to cause loss of the cable body in the relative sliding position, thereby reducing the quality of the finished cable. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a cable bracket for cable production, which can produce a relative rotational driving effect on a lower track pulley used to bear the pressure of the cable line, so that the lower track pulley has a tendency to rotate. The rotational torque strength formed by this tendency is close to the rotational resistance caused by the cable line to the lower track pulley, thereby offsetting the damping force of the cable line on the lower track pulley, so as to improve the following accuracy of the lower track pulley following the cable line in motion, reduce the occurrence of relative movement between the lower track pulley and the cable, thereby improving the finished product protection capability of the cable line, and solving the above-mentioned technical problems.

[0034] In order to achieve the relative friction driving effect on the lower track pulley 6, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6, it is necessary to set up a friction drive mechanism 9, which is provided with a lower horizontal hollow shell 91 rotating with the rotor 4 of the drive motor 3, an inner movable plate 911 located inside the lower horizontal hollow shell 91 and capable of rotating with the lower horizontal hollow shell 91, and a rotating friction plate 913 moving with the inner movable plate 911 and capable of abutting against the other end of the lower track pulley 6. When the drive motor 3 is started, the rotor 4 will drive the lower horizontal hollow shell 91 to rotate, the lower horizontal hollow shell 91 will drive the inner movable plate 911 to rotate, and the inner movable plate 911 will drive the rotating friction plate 913 to rotate. Since the lower track pulley 6 is subjected to the pressure of the cable, a large rotation torque resistance phenomenon will be generated, and the inner movable plate 911 will rotate at one end. Under the elastic force of the spiral spring 914, it will resist the rotating end face of the lower track pulley 6 with a certain pressure, and the maximum static friction force between the inner movable plate 911 and the lower track pulley 6 is close to but not greater than the torque resistance of the lower track pulley 6. The inner movable plate 911 will rotate at the rotating end face of the lower track pulley 6, and the rotation will cause the lower track pulley 6 to have a rotation trend, and the rotation direction needs to be consistent with the rotation direction of the lower track pulley 6 during the movement of the cable, thereby offsetting the damping force of the cable on the lower track pulley 6, so as to improve the follow-up accuracy of the lower track pulley 6 with the cable in motion, and reduce the occurrence of relative movement between the lower track pulley 6 and the cable.

The lower horizontal hollow shell 91 is provided with a piston body 99 capable of axial movement along the No. 1 component movable chamber 93 inside the No. 1 component movable chamber 93, and a No. 1 horizontal linkage rod 910 capable of rotating and passing through the No. 1 component through-hole 96 is installed on one end face of the piston body 99 through a bearing. The No. 1 horizontal linkage rod 910 is located at the No. 2 component movable chamber 93. An inner movable plate 911 capable of axially moving along the movable cavity 97 of the second component is fixedly installed at one end of the cavity 97. In order to realize the transmission of the rotation effect, it is necessary to make the structural shape of the cross section of the movable cavity 97 of the second component consistent with the structural shape of the cross section of the inner movable plate 911, both of which are polygonal structures, and the structural dimensions of the cross section of the movable cavity 97 of the second component match the structural dimensions of the cross section of the inner movable plate 911.

[0038] The specific working principle of the present invention is to fix the bottom support base plate 1 at the desired position, and at the same time, place the cable clamp between the lower track pulley 6 and the upper track pulley 7, and rotate the threaded sleeve 81, which will cause the lower external thread rod 87 and the upper external thread rod 88 to move away from or approach each other, thereby adjusting the distance between the lower track pulley 6 and the upper track pulley 7, so that the cable can be clamped between the lower track pulley 6 and the upper track pulley 7 with moving pressure;

Since the lower track pulley 6 is subjected to the pressure of the cable, a large rotation torque resistance phenomenon will be generated, and the inner movable plate 911 will resist the rotating end surface of the lower track pulley 6 with a certain pressure under the combined force of the No. 1 coil spring 914 and the gas pressure, and the maximum static friction force between the inner movable plate 911 and the lower track pulley 6 is close to but not greater than the torque resistance of the lower track pulley 6, and the inner movable plate 911 will rotate at the rotating end surface of the lower track pulley 6, and the rotation will cause the lower track pulley 6 to have a rotation trend, and the rotation direction needs to be consistent with the rotation direction of the lower track pulley 6 during the movement of the cable, thereby offsetting the damping force of the cable on the lower track pulley 6.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
