Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to a parallel pay-off tension adjustment device. Background Art

[0002] During the steel cord twisting process, controlling the pay-off tension is a critical step in ensuring consistent cord quality. Improper tension control can lead to excessive or insufficient tension during the twisting process, compromising the cord's quality and performance. Excessive tension can cause the cord to overtwist, leading to internal stress concentration and shortening its service life. However, insufficient tension can lead to looseness, wrinkling, and even residual torsion, severely impacting its performance.

[0003] During the production process, multiple pay-off devices pay off the wires together and twist them into ropes. If the pay-off tensions differ greatly, it may lead to quality defects or wire breakage. In addition, as the number of pay-off filaments decreases during operation, the pay-off tension will gradually change. Currently, workshop technicians regularly test and adjust the pay-off tension to ensure that the tension in all directions is consistent and changes synchronously to ensure product quality. However, this method still cannot maintain the consistency of the pay-off tension in real time. Utility Model Content

[0020] Figure 1 This is a schematic diagram of the first structure of the parallel pay-off tension adjustment device shown in the present utility model;

[0022] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0023] Combine Figure 1 and Figure 2 As shown, the present invention proposes a parallel pay-off tension adjustment device, which includes a plurality of pay-off shafts 10, a plurality of dampers 30, a damping adjustment component and a control component.

[0024] It should be understood that in the process of paying out wires simultaneously from multiple pay-out wheels and twisting them into ropes together, it is crucial that the tension of each steel wire is consistent. Therefore, in the present application, only one damping adjustment component is used for multiple pay-out wheels. The change in the thickness of the steel wire of any one of the multiple pay-out spools is detected by the damping adjustment component, and based on this, the tension of the pay-out shafts of all the spools is adjusted to make the pay-out tension of all the spools consistent.

[0025] The multiple pay-off shafts 10 are each rotatably connected to the mounting plate 20. The pay-off shaft 10 includes a mounting portion on a first side of the mounting plate 20 and a tension control portion on a second side of the mounting plate 20. The spool is mounted on the mounting portion of the pay-off shaft 10.

[0026] Furthermore, a damper 30 is connected to the tension control portion of each pay-off spool 10 for controlling the pay-off tension of the corresponding pay-off spool 10 during pay-off rotation. Optionally, the damper 30 comprises a magnetic damper. The damping adjustment component is mounted to the mounting plate 20 corresponding to one of the pay-off spools 10 and is used to detect the thickness of the wire on the pay-off reel mounted on the current pay-off spool 10.

[0027] It should be understood that during the pay-off process, the pay-off tension in the full wheel state and the empty wheel state is different. Therefore, it is necessary to adjust the damping force of the pay-off shaft 10 according to the degree of wire pay-off to ensure that the pay-off maintains a constant tension, and the damping adjustment component can provide feedback on the pay-off process according to the thickness of the wire on the surface of the pay-off wheel, so that the damper 30 controls the pay-off damping according to the pay-off situation to keep the tension constant.

[0028] Furthermore, the control component is configured to control the damping force of all dampers 30 on the pay-off shaft 10 according to the change in wire thickness on the pay-off wheel surface detected by the damping adjustment component, so that the pay-off tension of all I-shaped wheels is consistent and within a preset range.

[0029] In this way, by using the damping adjustment component to detect the wire guard state of only one I-spool and adjusting the wire payout damping of all I-spools based on this result, the consistency of the damping adjustment can be ensured to avoid deviation in the wire payout tension of each I-spool.

[0030] Combine Figure 1 and Figure 2 As shown, the damping adjustment component includes a rocker arm 42, a first end of the rocker arm 42 is rotatably connected to the mounting plate 20 via a turntable 41, and a second end is connected to a pressure wheel 43. The pressure wheel 43 maintains contact with the steel wire on the surface of the spool during the spool pay-off process, and the turntable 41 produces an angle change. The control component controls all the dampers 30 to produce a consistent change in the damping force on the pay-off shaft 10 according to the angle change of the turntable 41.

[0031] In this way, the pressure wheel 43 maintains contact with the surface of the steel wire layer. When the thickness of the steel wire layer gradually decreases, the angle of the rocker arm 42 changes, and the turntable 41 also rotates a certain angle. The control component can control all the dampers 30 to produce consistent damping force changes according to the angle change of the turntable 41, that is, all the pay-off shafts are subjected to the same damping force when rotating for pay-off, which is conducive to maintaining consistent pay-off tension on all pay-off wheels.

[0032] Furthermore, the control end of the damper 30 is configured as a rotating wheel structure. When the rotating wheel structure rotates to different angles, the damping force of the damper 30 on the pay-off shaft 10 changes.

[0033] Optionally, when the swing rod 42 swings downward as the thickness of the steel wire on the surface of the spool decreases, the pay-off tension decreases, and the damper 30 increases the damping force to compensate for it, so as to maintain the original pay-off tension.

[0034] Furthermore, in order to simultaneously control multiple dampers 30 through one feedback amount, the control component includes a transmission structure arranged between the turntable 41 and the multiple wheel structures. When the turntable 41 rotates, the transmission structure controls the synchronous rotation of the multiple wheel structures.

[0035] Among them, the mounting plate 20 is provided with a transition shaft 40, the turntable 41 is fixedly connected to the transition shaft 40, the mounting plate 20 and the transition shaft 40 are rotatably connected, and the outer wall of the wheel structure is provided with a belt transmission component 31, which is connected to the transition shaft 40.

[0036] Specifically, a connecting shaft 32 is provided on the side of the transition shaft 40 facing the damper 30 , an outer wall of the connecting shaft 32 is provided with teeth, an outer wall of the rotating wheel structure is also provided with teeth, and the belt transmission component 31 includes a synchronous belt.

[0037] In this way, when the transition shaft 40 rotates, the connecting shaft 32 rotates coaxially, and the belt transmission component 31 serves as a transmission structure between the wheel structure and the connecting shaft 32, so that the wheel structure rotates synchronously, thereby adjusting the damping force of the damper 30.

[0038] Combine Figure 1 As shown, if a plurality of spools are arranged with their axes coinciding, for example, the axes of the first spool 100 and the second spool 200 coincide, the transition shafts 40 between each mounting plate 20 are connected via a coupling 50 .

[0039] In this way, through the connection of the coupling 50 , the connecting shaft 32 on one side of each transition shaft member 40 will rotate synchronously.

[0040] Combine Figure 2 As shown, if multiple I-shaped wheels are arranged in a front-to-back arrangement, for example, the first I-shaped wheel 100 and the second I-shaped wheel 200 are arranged in a front-to-back arrangement in the line-releasing direction, a connecting plate 52 is provided on the surface of each turntable 41, and adjacent connecting plates 52 are hingedly connected by connecting rods 51. The rotation angles of all turntables 41 are consistent during rotation to ensure the consistency of the damper adjustment.

[0041] In this way, two adjacent connecting plates 52 and connecting rods 51 form a four-bar structure. When one of the turntables 41 rotates, all the turntables 41 rotate at the same angle to ensure the consistency of the damper adjustment.

[0042] In combination with the above embodiments, the tension adjustment device proposed by the utility model is particularly suitable for scenarios where multiple pay-off wheels pay out wire synchronously. By arranging a damping adjustment component on the surface of one of the I-spools, the damping force applied to all the I-spool shafts during pay-off can be adjusted according to the change in the thickness of the steel wire on the current I-spool surface. Therefore, the damping force applied to all the I-spools during pay-off is the same, which helps all the I-spools maintain consistent tension during pay-off to achieve better twisting effect, and also saves the trouble of separately configuring a rocker arm for each damper.

[0043] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
