when the turntable 34 drives the tension detection mechanism 4 to rotate (for example, the arrow direction in fig. 7 rotates by 90 °), the positions of the original measuring bars 45 are exchanged according to the circumferential direction, so that after the turntable 34 rotates for one circle, the same point on the screen is measured by different measuring bars 45 to obtain multiple groups of tension values, thereby realizing multiple tension detection on a single point on the screen by the measuring bars 45 at different positions and improving tension detection precision of the screen;
the second method is as follows: as shown in fig. 3 and 8, the measuring rods 45 are disposed within the upper range of the peripheral end of the cover plate 42, and the positions of the four sets of measuring rods 45 are asymmetric to each other, and the four sets of measuring rods 45 are close to or far from the center of the cover plate 42;
meanwhile, a group of measuring rods 45 are arranged at the center of the cover plate 42, a plurality of groups of measuring rods 45 are arranged at the periphery of the measuring rods 45 at the center of the cover plate 42, and the plurality of groups of measuring rods 45 are asymmetric;
when the turntable 34 drives the tension detection mechanism 4 to rotate (for example, the arrow direction in fig. 8 rotates by 90 °), the positions of the measuring bars 45 are exchanged according to the circumferential direction, and the measuring bars 45 are asymmetric with each other, so that when the rotating measuring bars 45 detect tension of the screen, new tension detection points are formed on the screen (for example, a schematic diagram at the lower part in fig. 8 and the dotted line in the diagram is the position where the original measuring bars 45 are located), therefore, after the turntable 34 rotates for a circle, a plurality of groups of points are formed on the screen and tension values corresponding to the detection points are formed, thereby achieving the purpose of increasing the tension detection points of the screen, and improving the detection accuracy of tension of the screen.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
