Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of cable production, and particularly relates to a wire winding and unwinding tension control system for an optical cable production line based on digital twin. Background Art
[0002] Optical cables are the cornerstone of the development of the communication and Internet industries. The cable industry represented by optical cables is the second largest manufacturing industry in China after the automotive industry, and the product variety satisfaction rate and market share exceed 90%. Tight wrapping means adding a very thin sheath to the outer layer of the optical fiber for protection to avoid the internal optical fiber being affected by external mechanical, thermal, chemical, and moisture. In all the technological processes of producing indoor optical cables, the production of tight-buffered optical fiber is an indispensable process.
[0003] Constant tension system control is the ability to continuously control the raw material when it is conveyed on the equipment and maintain a constant tension, including mechanical tension control devices, electronic tension control devices, and magnetic flux tension control devices. Currently, in the non-metallic material laminating equipment in the electronics industry, during operation, the tension of the material is controlled by the magnetic powder brake or magnetic powder clutch of the unwind and rewind shafts. The disadvantage of this control method is that as the coil diameter changes during material winding or unwinding, the tension of the material will change accordingly, which will cause the material to be stretched and deformed inconsistently, resulting in product defects, especially for materials that are thin or easily stretched and deformed. In view of the above situation, one existing method is to change the motor of the take-up shaft to a servo motor and control the material tension through the torque control mode of the servo motor, but this control method is too costly. Summary of the Invention
[0004] The purpose of the present invention is to provide a wire winding and unwinding tension control system for an optical cable production line based on digital twin to solve the problem that the tension of the optical cable production line in the prior art is difficult to control.
[0005] The technical solution of the present invention is as follows: A wire winding and unwinding tension control system for an optical cable production line based on digital twin, comprising: The driving device includes a rotating motor, a gear is installed at the output end of the rotating motor, the gear, and a gear ring is engaged with the gear, and the gear ring is fixedly connected to the end face bearing.
[0006] In order to enable the present invention to have the function of avoiding optical cable signal shielding, further, the material of the mounting ring is plastic.
[0007] In order to enable the present invention to have the function of clamping the optical cable, further, the clamping assembly includes a mounting groove fixedly arranged on the mounting ring, a movable rod is arranged in the mounting groove along its length direction, a pressure detector is fixedly arranged at one end of the movable rod, and an elastic member is installed between the mounting groove and the movable rod.
[0008] The elastic member is a spring. One end of the spring is fixedly arranged on the installation groove, and the other end is fixedly arranged on the movable rod.
[0009] In order to enable the present invention to drive the clamping assembly to move, further, the pushing member includes a pushing arc that is concentrically arranged with the mounting ring on the end face bearing, and the pushing arc for driving the clamping assembly to move is mounted on the end face bearing.
[0010] In order to enable the present invention to drive the pushing member to operate, further, the driving device includes a rotating motor. A gear is installed at the output end of the rotating motor. There is a toothed ring meshed with the gear, and the toothed ring is fixedly connected to the end face bearing.
[0011] The beneficial effects of the present invention are as follows: The driving device drives the pushing member to rotate. When the pushing member rotates, it drives the clamping assembly to move. When the clamping assembly moves, it clamps the cable. When the cable is clamped, the pressure detector can display the clamping force of the clamped cable. At this time, through the signal connection between the driving device and the pressure detector, the rotation of the driving device is controlled. When the clamping force on the cable is large, after being detected by the pressure detector, through the rotation of the driving device, the clamping force is reduced. When the clamping force on the cable is small, after being detected by the pressure detector, through the rotation of the driving device, the clamping force is increased, thereby adjusting the clamping of the optical cable and further adjusting the tension of the optical cable.
