Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cable production, in particular to a controllable tension stabilizing device for cable production. BACKGROUND

[0002] In the cable production process, tension control is one of the links to ensure the quality of cable products. Proper tension can ensure smooth transmission of the cable in each process (such as twisting, insulation layer wrapping, and armoring), prevent cable deformation and insulation layer damage caused by excessive stretching, and prevent cable accumulation and winding caused by insufficient tension.

[0003] For example, the patent with the publication number CN218619624U specifically discloses a cable production equipment tension adjusting structure, which includes a box body, a winding wheel, a rotating wheel, a threaded rod, a sliding rail A, a moving block, a sliding rail B, and a threaded rod B. The beneficial effects of the present application lie in that the threaded rod B, the sliding block, and the gears A and B are provided, the two gears are engaged by rotating the threaded rod B, the threaded rod A can be fixed, the movement of the threaded rod A caused by external force or accidental touch of the motor is avoided, and the stability of the device after tension adjustment is improved.

[0004] However, the cable production equipment tension adjusting structure of the above-mentioned patent only relies on a single guide wheel to adjust the tension, and the guide wheel can only drive the moving block along the sliding rail A to adjust the overall position in the vertical direction. It is not easy to change the contact mode or the lateral adaptive spacing according to the diameter and material differences of the cable. For thicker diameter cables, the guide range of the single guide wheel is not easy to cover the cross-sectional size, and the cable edges are prone to extrusion and friction with the side wall of the guide wheel, which may cause damage to the insulation layer or surface wear. For thinner diameter cables, the single guide wheel is difficult to provide sufficient lateral constraint, and the cable is prone to shift during transmission, which may cause tension fluctuations, winding, and accumulation problems. Therefore, it is necessary to provide a controllable tension stabilizing device for cable production to solve the above-mentioned problems. SUMMARY

DETAILED DESCRIPTION

[0017] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0018] In order for those skilled in the art to better understand the technical scheme of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0019] As Figure 1 and Figure 2As shown, this application provides a controllable tension stabilizing device for cable production, including an assembly frame 1. Two sets of mounting holes 11 are provided at the four corners of the assembly frame 1. The mounting holes 11 are provided to facilitate the secure installation of the entire device on the relevant equipment or production line for cable production using fasteners such as bolts.

[0020] Multiple sets of symmetrically arranged first guide wheels 12 and second guide wheels 13 are bolted to the outer wall of one side of the assembly frame 1. During the production and transmission process, the cable will pass through these first guide wheels 12 and second guide wheels 13 in sequence. They can play a preliminary guiding role for the cable and also maintain the tension of the cable to a certain extent.

[0021] like Figures 1 to 3 As shown, a tension adjustment assembly 2 is installed on the assembly frame 1. The tension adjustment assembly 2 includes a lifting motor 21 bolted to the upper part of the assembly frame 1. The lifting motor 21 serves as the power source for the entire tension adjustment assembly 2. After being powered on, it provides power to the rotation of the long lead screw section through the corresponding PLC controller, thereby driving the subsequent structure to achieve vertical movement to adjust the cable tension. The output end of the lifting motor 21 passes through the assembly frame 1 and is coaxially mounted with a one-way long lead screw 22. The one-way long lead screw 22 is designed to convert the rotational motion of the lifting motor 21 into linear motion using the principle of lead screw transmission. One end of the one-way long lead screw 22 is rotatably connected to the bottom of the assembly frame 1. This rotatable connection method can ensure that the one-way long lead screw 22 remains stable during rotation and is not prone to axial deviation, thus ensuring the accuracy of transmission.

[0022] One-way slider 23 is threadedly connected to the body of the one-way long screw 22. When the one-way long screw 22 rotates under the drive of the lifting motor 21, the one-way slider 23 will move vertically along the length of the one-way long screw 22 due to the meshing of the threads. A slide groove 231 is provided in the middle of the assembly frame 1. A bracket 232 that can slide along the slide groove 231 is installed on the one-way slider 23 by bolts. The slide groove 231 is set to guide the movement of the bracket 232 and prevent the bracket 232 from deviating or shaking during the movement. A support plate 233 is installed on the support 232 by bolts. The support plate 233 is the installation base of the segmented adapter part. The segmented adapter part will move vertically together with the support plate 233, thereby realizing the adjustment of cable tension.

[0023] On the other side of the assembling frame 1, two groups of guide rods 25 are bolted, and on both sides of the one-way sliding block 23, two groups of guide sleeves 24 capable of sliding along the guide rods 25 are bolted. The guide sleeves 24 and the guide rods 25 cooperate with each other to further guide and limit the movement of the one-way sliding block 23, prevent the one-way sliding block 23 from rotating during movement, ensure the stability of the movement of the entire tension adjusting assembly 2 in the vertical direction, and make the tension adjustment more accurate.

[0024] As shown in Figure 1 、 Figure 4 and Figure 5 , a segmented adaptation assembly 3 is installed on the support plate 233. The segmented adaptation assembly 3 includes an L-shaped plate 31 bolted to the support plate 233. An adjusting motor 32 is bolted to the lower part of the L-shaped plate 31. When the adjusting motor 32 is powered on, it can provide power to the segmented adaptation assembly 3 through the corresponding PLC controller. The output end of the adjusting motor 32 penetrates the L-shaped plate 31 and is coaxially installed with a bidirectional screw rod 33. The bidirectional screw rod 33 is a prior art. The thread directions of the two ends are opposite, so that when it rotates, it can drive two groups of sliding block parts to move closer to each other or farther away from each other. One end of the bidirectional screw rod 33 is rotationally connected to the upper part of the L-shaped plate 31. This connection mode ensures the stability of the bidirectional screw rod 33 during rotation and is not prone to axial movement. Two groups of bidirectional sliding blocks 34 are threadedly connected to the shaft of the bidirectional screw rod 33. Since the thread directions of the two ends of the bidirectional screw rod 33 are opposite, when the bidirectional screw rod 33 rotates under the drive of the adjusting motor 32, the two groups of bidirectional sliding blocks 34 will move closer to each other or farther away from each other along the length direction of the bidirectional screw rod 33.

[0025] Two groups of limiting rods 35 are bolted to the middle part of the support plate 233. Limiting sleeves 351 capable of sliding along the rod are respectively sleeved on the limiting rods 35. The limiting rods 35 provide a track for the sliding of the limiting sleeves 351. A connecting rod 36 is hingedly connected to both sides of the bidirectional sliding block 34. The connecting rod 36 functions as a transmission, converting the movement of the bidirectional sliding block 34 into the sliding of the limiting sleeve 351. One end of the connecting rod 36 is respectively hingedly connected to the limiting sleeve 351. This hinged connection mode makes the connecting rod 36 have a certain flexibility during transmission, which can adapt to the relative movement between the bidirectional sliding block 34 and the limiting sleeve 351. A connecting frame 37 is installed on one side of the limiting sleeve 351 through bolts, and an adjusting wheel 38 is installed on the connecting frame 37 through bolts, wherein, with the movement of the limiting sleeve 351, the connecting frame 37 drives the adjusting wheel 38 to move together, the adjusting wheel 38 is a component directly in contact with the cable, by adjusting the position of the adjusting wheel 38, the contact mode and lateral spacing of the adjusting wheel 38 with the cable can be changed, so as to adapt to cables of different diameters and materials, prevent the cable edge from being squeezed and rubbed with the guide wheel side wall or the cable from shaking and deviating, and ensure the tension stability of the cable during transmission.

[0026] Working principle: when in use, first, the device is stably installed at a suitable position of the cable production line through the mounting hole 11 on the assembly frame 1 by bolts, providing a basis for subsequent tension stability control in the cable transmission process, in the initial stage of cable transmission, the cable will pass through the first guide wheel 12 and the second guide wheel 13 in turn, which plays a preliminary guiding role on the cable, ensuring that the cable can be transmitted according to the predetermined path; When the tension of the cable needs to be adjusted, the lifting motor 21 in the tension adjusting assembly 2 is started, under the precise control of the PLC controller, the lifting motor 21 starts to operate and drives the one-way long screw rod 22 to rotate, since the one-way sliding block 23 and the one-way long screw rod 22 are connected in a threaded manner, and the guide sleeve 24 can slide along the guide rod 25, which plays a good guiding role, so that during the rotation of the one-way long screw rod 22, the one-way sliding block 23 moves vertically along the length direction of the one-way long screw rod 22; With the movement of the one-way sliding block 23, the bracket 232 installed on the one-way sliding block 23 slides along the sliding groove 231 in the middle of the assembly frame 1, thereby driving the branch plate 233 and the segmented adaptation assembly 3 installed on the branch plate 233 to move vertically synchronously, through this vertical position adjustment, the relative positional relationship between the adjusting wheel 38 and the cable can be changed, so as to realize the preliminary adjustment of the cable tension; If the lateral spacing of the adjusting wheel 38 needs to be adjusted according to the diameter size and material characteristics of the cable, so as to better adapt to cables of different specifications, the adjusting motor 32 in the segmented adaptation assembly 3 needs to be started, under the control of the PLC controller, the adjusting motor 32 starts to work and drives the bidirectional screw rod 33 to rotate, since the screw threads on the two ends of the bidirectional screw rod 33 are opposite in rotation direction, when the bidirectional screw rod 33 rotates under the drive of the adjusting motor 32, the two groups of bidirectional sliding blocks 34 sleeved on the bidirectional screw rod 33 will move towards or away from each other along the length direction of the bidirectional screw rod 33; When the bidirectional slider 34 moves, the limiting sleeve 351 will slide along the limiting rod 35 through the connecting rod 36 hingedly connected therewith, and the connecting frame 37 is installed on the limiting sleeve 351, so with the sliding of the limiting sleeve 351, the connecting frame 37 will drive the adjusting wheels 38 to move synchronously, for the cable with a larger diameter, the operator can control the adjusting wheels 38 to move away from each other, so as to expand the guiding range of the adjusting wheels 38 to the cable, prevent the edge of the cable from being pressed and rubbed with the side wall of the adjusting wheels 38, and prevent the cable insulation layer from being damaged, and for the cable with a smaller diameter, the two groups of adjusting wheels 38 are controlled to move close to each other, so as to provide sufficient lateral constraint for the cable, effectively prevent the cable from shaking and deviating during transmission, and ensure that the cable can be stably transmitted.

[0027] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
