Description

TECHNICAL FIELD

[0001] The utility model relates to the processing technical field of wire and cable industry more particularly to a tungsten wire tension control system. BACKGROUND

[0002] The tension control method in the market at present is for the constant tension control of the double-end fixed system of one side unwinding and one side winding. In these tension control systems, the controlled target is always in motion. By adjusting the speed difference between the unwinding speed and the winding speed, the tension changes according to the control requirements. This scheme has been relatively mature and can meet the basic needs of the industry. For example, the invention application with the application number of 201811010212.2 discloses a constant tension pay-off control device, which comprises a support frame, a swing arm, a single-wheel fixed guide wheel, a first guide wheel set, a second guide wheel set, a driving motor, a swing arm shaft and a feedback system. The driving motor speed can be adjusted to adjust the pay-off speed, and the position of the counterweight can be adjusted to adjust the swing arm's force arm. When in use, the wire is first connected from the pay-off wheel and then passes through the first guide wheel set and the second guide wheel set to the single-wheel fixed guide wheel. The driving motor is turned on. There is a certain deviation between the actual tension of the wire and the set tension. The swing arm will deviate upward or downward from the horizontal position. When the angle detection sensor detects that the swing arm deviates, it will send a signal to the controller. The controller adjusts the speed of the driving motor to make the swing arm horizontal.

[0003] The improved tension control method is disclosed in the invention application with the application number of 200910181988.5, which discloses a design method of a pay-off constant tension control device in a wire winding system. A servo motor and a pay-off wheel are arranged on the rack. The servo motor drives the pay-off wheel. Two fixed pulleys and a movable pulley are arranged on the rack behind the pay-off wheel to form a pulley set. The movable pulley is between the two fixed pulleys. The movable pulley is installed on a swing lever, which is hinged to the rack and hinged to the rack by a cylinder. The piston rod of the cylinder is drivingly connected to the swing lever. A tension sensor is also arranged on the rack behind the pulley set. The wire rope output by the pulley set is guided into the tension sensor. The wire rope of the tension sensor is pulled to the take-up host.

[0004] However, since the movable pulley and the piston rod of the cylinder are drivingly connected to the swing lever, the motion trajectory will sometimes cause deviation, which can only produce cables with relatively low requirements. UTILITY MODEL CONTENTS
