Wire and cable take-up control system

Abstract

The invention discloses a wire and cable take-up control system. The wire and cable take-up control system comprises a direct-current take-up speed regulator in control connection with a take-up motor, an alternating-current connection end of the direct-current take-up speed regulator is used for being connected with a three-phase alternating-current network through a contactor switch; an armature wiring end and an excitation end of the direct-current take-up speed regulator are correspondingly connected with an armature wiring end and an excitation end of the take-up motor; a speed given potentiometer is connected to a first analog input end of the direct-current take-up speed regulator, a tension given potentiometer is connected to a second analog input end of the direct-current take-up speed regulator, and a speed detection mechanism is connected to a speed feedback end of the direct-current take-up speed regulator. Take-up tension is basically kept unchanged when take-up coil diameter changes, the take-up speed can automatically follow the pulling speed for stable operation as long as the two potentiometers adjust properly, and no extra wire storage tension mechanism is needed. In addition, the wire and cable take-up control system has the advantages of stability in transmission, convenience in mounting, functional powerfulness, complete protection functions and optimal cost performance.

Description

technical field [0001] The invention relates to a wire and cable take-up control system. Background technique [0002] Usually, the transmission of the cable production line uses a DC motor, and the speed control device of the DC motor is a speed control system composed of domestic discrete components. The fault point is not easy to find and eliminate, which is extremely unfavorable for the continuous production device; and the domestic DC speed control device has only one analog input port and one output port, and it is impossible to process the analog signal of the multi-division transmission, let alone the The extension of the analog signal and the control of the winding speed of the take-up device is a difficult link in the automatic control system of the cable production line. The winding speed can only be controlled by the speed controller, and the winding speed can only be changed by manually adjusting the winding speed setting. If the adjustment is not timely, the c...

[0002] Usually, the transmission of the cable production line uses a DC motor, and the speed control device of the DC motor is a speed control system composed of domestic discrete components. The fault point is not easy to find and eliminate, which is extremely unfavorable for the continuous production device; and the domestic DC speed control device has only one analog input port and one output port, and it is impossible to process the analog signal of the multi-division transmission, let alone the The extension of the analog signal and the control of the winding speed of the take-up device is a difficult link in the automatic control system of the cable production line. The rewinding speed is controlled by the speed controller, and the rewinding speed can only be changed by manually adjusting the rewinding speed setting. If the adjustment is not timely, the cable thickness will be uneven.

[0003] like figure 1 Shown is a schematic diagram of a wire take-up mechanism using a traditional speed regulating device. In the wire take-up mechanism, a wire storage tension device 2 is set between the traction device 1 and the wire take-up device 6. The wire storage device includes a tension swing rod 5 The tension potentiometer 3 connected with the wire storage tension wheel 4; this structure also has the automatic speed control system for the wire take-up of the cable production line disclosed in the patent application number 2014201682164. The given signal input end of the line controller is connected with a tension potentiometer. The tension potentiometer is connected to the wire storage tension wheel on the wire inlet side of the winding motor through the transmission mechanism. The tension potentiometer controls the wire storage tension wheel The position control realizes the adjustment of the winding speed, and the structure of this winding control system is relatively complicated.
