Detailed Description
The invention is further illustrated by the following figures and examples.
As shown in figures 1 and 2, the invention relates to a yarn on-line tension detection device used in high-speed chemical fiber production, which is characterized in that an S-shaped resistance type tension sensor fixing seat 2 is arranged on the front surface of a vertical base 3, the bottom surface of the S-shaped resistance type tension sensor 1 is connected with the top surface of the S-shaped resistance type tension sensor fixing seat 2, the top surface of the S-shaped resistance type tension sensor 1 is connected with a detection pulley base 7, a first U-shaped groove ceramic pulley 11 is arranged on the upper portion of the detection pulley base 7, a screw rod motor 4 is arranged at the center of the bottom surface of the vertical base 3, a linear guide rail bearing seat 6 is arranged in a groove at the center of the vertical base 3, one end of a linear guide rail 5 is connected with a rotating shaft of the screw rod motor 4, the other end of the linear guide rail 5 passes through the linear guide rail bearing seat 6 and then is connected with the bottom surface of a movable pulley base 8, a second U-shaped groove ceramic pulley 10 and a third U-shaped groove ceramic pulley 12 are respectively arranged on two sides of the movable pulley base 8, a laser sensor 9 for detecting the descending of the second U-shaped groove ceramic pulley 10 and the third U-shaped groove ceramic pulley 12 to the detection position is arranged on one side of the top surface of the vertical base 3. The lead screw motor 4 controls the up-and-down movement of the second U-shaped groove ceramic pulley 10 and the third U-shaped groove ceramic pulley 12 through the linear guide rail 5 and the movable pulley base 8.
As shown in fig. 3, in a non-detection state, the centers of the first U-shaped groove ceramic pulley 11, the second U-shaped groove ceramic pulley 10, and the third U-shaped groove ceramic pulley 12 form an isosceles triangle distribution.
When the yarn tension detecting device is in a non-detection state, the screw rod motor 4 controls the second U-shaped groove ceramic pulley 10 and the third U-shaped groove ceramic pulley 12 to ascend to the highest position through the linear guide rail 5. As illustrated in fig. 2, the yarn 13 is not in contact with the first U-groove ceramic pulley 11, the second U-groove ceramic pulley 10, the third U-groove ceramic pulley 12, and other structures, further reducing friction during yarn production.
As shown in fig. 4, during tension detection, the yarn 13 to be detected can pass through the lower part of the third U-shaped groove ceramic pulley 12 on the left side and the upper part of the first U-shaped groove ceramic pulley 11 in the middle and pass out of the lower part of the second U-shaped groove ceramic pulley 10 on the right side. The yarn is wound around the three U-shaped groove ceramic pulleys, and the tension of the yarn can be completed by using a three-point bending force measuring method.
When the yarn tension needs to be detected, the lead screw motor 4 controls the second U-shaped groove ceramic pulley 10 and the third U-shaped groove ceramic pulley 12 to descend to the optimal tension detection position through the linear guide rail 5, and the laser sensor 9 is used for limiting the descending positions of the second U-shaped groove ceramic pulley 10 and the third U-shaped groove ceramic pulley 12. And the yarn 13 to be detected which runs at high speed is ensured to be vertical to the installation bottom surface of the structure body in the vertical direction through precise mechanical design, manufacturing and precise installation. The yarn tension F acts on the S-type resistive tension sensor 1 in real time by detecting the force F1 in the vertical direction of the pulley base 7.
Because in the chemical fiber production process, the production performance is stable, so the structure can be adopted to realize discontinuous yarn tension detection. And chemical fiber production process is fast, utilizes the friction of discontinuity yarn tension detection reducible pulley, increases its life to do not influence the testing result.
