Description

TECHNICAL FIELD

[0001] The utility model relates to the cable production field especially relates to a cable production wire feeding tension pulley mechanism. BACKGROUND

[0002] Cable is a kind of electric energy and signal transmission device, usually by several or several groups of wires. Winding is an important link in the process of cable production, the whole winding process, cable core contact extension is very long, in this case, cable needs to maintain a certain degree of tension, to maintain its continuity and consistency on the production line. If cable appears over-tension or too loose, not only will cause deviation and error in the production process, also can lead to cable breakage etc., thereby influence product quality and performance, even lead to the damage of production line related equipment. In order to deal with this challenge, cable production wire feeding tension pulley mechanism arises at the historic moment.

[0003] The main role of cable production wire feeding tension pulley mechanism is to ensure that raw materials maintain tension when feeding into the production line. However, there are some problems to be solved in the design and use of cable production wire feeding tension pulley mechanism. Due to the design or manufacturing defects of tension pulley mechanism, and the wear and tear and aging in the long-term use process, the tension force can not be kept stable. This instability will affect the tension state of the cable, and then cause deviation and error in the production process, and even can lead to the damage of cable. And, the design precision of some adjusting mechanism is insufficient, which can not realize accurate tension force adjustment. This will cause the cable to be unable to maintain the best tension state in the production process, affecting the production efficiency and cable quality. The applicant has applied some tension pulley groups for cable production early, such as CN209507322U can realize tension self-adjusting function, but lacks real-time detection of tension data, CN209601833U can also realize self-adjusting function, but the number of tension pulleys is too much, and the land occupation is large, CN210854759U discloses the tension pulley group structure is simple, and the land occupation is small, but the monitoring function is weak, and only small amplitude displacement change can be monitored.

[0044] Embodiment 1

[0045] The embodiment provides a highly integrated and intelligent cable production wire feeding tension pulley mechanism, and the specific structure includes:

[0046] The support member includes a stand (2) and a fixed seat (7), the tension pulley set includes a first tension pulley (1) and a second tension pulley (3), and the adjusting member includes a fixed beam (6) and a rotating arm (8).

[0047] Referring to Figures 1-2 The fixed seat (7) is placed at the bottom, for example, can be fixed on the ground or other support parts, and the stand (2) is vertically installed on the fixed seat (7) to provide support for the whole mechanism.

[0048] The first tension pulley (1) is rotatably connected to the stand (2) through a first tension pulley rotating shaft, for example, can be connected to the top of the stand (2).

[0049] Referring to Figures 1-2The fixed beam (6) is fixed horizontally on the stand column (2), for example, one end of the fixed beam (6) is fixedly connected to the stand column, and the other end (free end) extends horizontally. The fixed beam (6) is located below the first tensioning wheel (1), and the fixed beam (6) serves as a support structure of the rotating arm (8).

[0050] The rotating arm (8) is connected to the fixed beam (6) through a rotating shaft (12), the rotating shaft (12) penetrates through the fixed beam (6), and the rotating arm (8) can rotate freely in a vertical plane around the rotating shaft (12).

[0051] One end of the rotating arm (8) is connected to the second tensioning wheel (3) through a second tensioning wheel shaft, and the other end is connected to the detachable counterweight (4). The rotating shaft (12) is located in a region between the second tensioning wheel (3) and the counterweight (4). Moreover, the rotating shaft (12) is closer to the counterweight, and the rotating arm (8) becomes a lever with the rotating shaft (12) as a fulcrum. Meanwhile, the stand column (2) is located between the second tensioning wheel shaft and the rotating shaft (12), so that the second tensioning wheel (3) is located below the first tensioning wheel (1). Thus, through rotation of the rotating arm, the second tensioning wheel (3) moves along a circular arc with the rotating shaft (12) as a center and the length from the rotating shaft (12) to the second tensioning wheel shaft as a radius, so as to automatically adjust the position of the second tensioning wheel through change of the cable tension, change the cable tension, and realize accurate control of the cable tension.

[0052] The counterweight (4) can be made of metal or alloy, and is detachably and slidably installed on the rotating arm (8). Through precise cooperation of a sliding groove and a guide rail, the counterweight (4) can stably slide on the rotating arm (8), and it is convenient for an operator to adjust according to cable specifications and tension requirements.

[0053] One end of the rotating shaft (12) penetrates through the fixed beam and is connected to a mounting plate (5), the mounting plate (5) is provided with an angle sensor (14) for detecting rotation conditions such as rotation speed, angle and radian of the rotating shaft (12), and transmitting in real time to a cable feeding mechanism (which can be transmitted through a network). In the patent, when the cable feeding speed changes, the tension between the first tensioning wheel (1) and the second tensioning wheel (3) changes, the tension change drives the second tensioning wheel (3) to move, and the rotating shaft (12) rotates accordingly. Therefore, the rotation parameters of the rotating shaft (12) obtained by the angle sensor (14) can be used to calculate the cable feeding speed according to a budget calculation formula or a curve.

[0054] Embodiment 2

[0055] On the basis of embodiment 1, the intelligent monitoring and control are optimized in the embodiment.

[0056] Between the rotating shaft (12) and the mounting plate (5), a large gear (11) and a small gear (13) are arranged, the large gear (11) is connected to the rotating shaft (12) and rotates with the rotating shaft (12), the large gear (11) is engaged with the small gear (13), and the small gear (13) rotates with the large gear (11). When the rotating arm (8) rotates through the rotating shaft (12), it will drive the large gear (11) to rotate, and in turn drive the small gear (13) to rotate.

[0057] In this embodiment, the angle sensor (14) is used to detect the rotation angle, speed or number of revolutions (or radians) of the small gear (13), and transmit these data to the cable supply mechanism in real time. According to the received data, the cable supply mechanism can flexibly adjust the cable supply speed to maintain the balance of the cable tension. The rotation speed or arc of the small gear (13) is easier to be discovered by the angle sensor (14), so the monitoring data is more accurate.

[0058] Embodiment 3

[0059] On the basis of embodiment 1, this embodiment also carries out visual operation and adjustment, as follows:

[0060] The scale (10) is installed on the entire area of the rotating arm (8), which facilitates the operator to intuitively understand the influence of the position of the counterweight (4) on the cable tension, and to make accurate adjustment. Alternatively, a scale can be drawn on the rotating arm (8).

[0061] Before the production of the cable, the relationship between the tension of the cable applied to the second tensioning wheel (3) and the cable conveying speed can be calculated or measured, according to the principle of lever, the counterweight (4) is intuitively arranged at the required position through the scale, and then fine adjustment can be made.

[0062] Embodiment 4

[0063] On the basis of embodiment 1, this embodiment also provides a rotating arm position detector (9), which is arranged on the stand (2) and can be a pressure sensor, etc., for real-time monitoring of the position of the rotating arm (8). This embodiment is provided with two rotating arm position detectors (9), which are respectively installed above and below the rotating arm (8), to achieve more comprehensive fault detection.

[0064] Although the angle sensor (14) can obtain the cable conveying speed and the rotation of the rotating arm (8) in real time, if an accident occurs, for example, the wire feeding mechanism suddenly fails, causing the wire feeding speed to drop rapidly, or the wire feeding speed continues to drop, the second tensioning wheel (3) will be pulled up, and the rotating arm (8) or the second tensioning wheel (3) will touch the upper rotating arm position detector (9), and the rotating arm position detector (9) sends a signal to the wire feeding mechanism or the console, and according to the received signal, the wire feeding mechanism can be stopped by manual operation or the console. Conversely, if the wire feeding speed is too fast, or the direction speed continues to increase, the second tensioning wheel (3) will rotate downward, and similarly, the lower rotating arm position detector (9) is triggered.

[0065] Therefore, when the cable feeding speed is too fast or too slow, causing the rotating arm to move too much, the rotating arm position detector (9) will timely send an alarm signal or a control signal to prevent the fault from expanding.

[0066] The cable production wire feeding tensioning wheel mechanism has the following obvious advantages:

[0067] Through the position change of the second tensioning wheel (3) on the rotating arm (8) and the design of the counterweight block (4), the function of automatically adjusting the cable tension according to the change of the cable conveying speed is realized, and the stability and quality of the cable in the production process are ensured.

[0068] The introduction of the monitoring and control system enables the wire feeding mechanism to flexibly adjust the wire feeding speed according to the data feedback by the angle sensor (14), further improving the control accuracy of the cable tension.

[0069] The setting of the scale (10) and the addition of the visual operation and adjustment function enable the operator to intuitively understand the influence of the position of the counterweight block (4) on the cable tensioning and accurately adjust, improving the convenience and accuracy of the operation.

[0070] The above only describes the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation or direct / indirect application in other related technical fields under the utility model concept of the utility model is included in the patent protection range of the utility model.
