Abstract

The invention discloses an automatic tensioning device for carbon fiber rods, which comprises a base, a frame, a pressure sensor of a driving wheel pinch wheel, a pinch wheel adjustment mechanism and a servo motor, and is characterized in that the frame is connected to the base track; the The driving wheel is set on the frame and driven by the servo motor; the pressure wheel is set on the frame and is opposite to the driving wheel; the pressure sensor is set At the front end of the base, it is arranged opposite to the front end plate of the frame; the front end plate of the frame is also provided with a wiring hole for the carbon fiber rod to pass through; the feedback signal of the servo motor through the pressure sensor Adjust the speed. The invention directly senses the dynamic tension force of the carbon fiber rod, accurately controls the feeding speed of the carbon fiber rod, ensures that the tension force of the carbon fiber is within a standard range, and ensures the winding quality.

Description

technical field [0001] The invention relates to an auxiliary mechanism of a carbon fiber rod winding testing machine, in particular to an automatic tensioning device for a carbon fiber rod. Background technique [0002] The carbon fiber rod winding test machine is a test equipment for winding carbon fiber rods onto the skeleton. Its working principle is that the motor drives the skeleton to rotate, and the carbon fiber rods are wound onto the skeleton layer by layer. During the winding process, the carbon fiber rod needs to be pulled by a constant tension force. Since the carbon fiber rod is moving during the winding process, it is very difficult to control its tension. Conventional control methods use indirect means, such as the three-point tension method, that is, three measurement points are selected on the carbon fiber rod to measure the tension between them. Another way is to use the electromagnetic principle to measure the output torque of the skeleton drive motor a...
