Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester web production technology, and more specifically to an online tension testing device for polyester web production. Background Technology
[0002] Polyester mesh is a type of mesh fabric woven using various weaving methods on textile machinery. Its main uses include drying and filtration. It features acid resistance, high temperature resistance, wear resistance, and a long service life. The mesh surface is flat, with strong tensile strength and good air permeability. Polyester mesh is widely used in various industries, including papermaking, wastewater treatment, coal washing, pharmaceuticals, ceramics, food, and printing. During the processing and production of polyester mesh, tension testing is usually required. Currently, tension testing typically involves clamping the ends of the polyester mesh with fixtures and stretching it. However, during the stretching process, the stability of the clamps holding the ends of the polyester mesh is not high, allowing the ends of the mesh to easily detach from the fixtures, thus affecting the tension test results. This method needs improvement. Utility Model Content

Then, the knob 25 and screw 26 are rotated. The screw 26 moves the slider 27, push plate 28, and push rod 29. One end of the push rod 29 moves the anti-slip clamping plate 291, clamping the polyester mesh between the anti-slip clamping plate 291 and the clamping channel 23, fixing the outer wall of one end of the polyester mesh. At this time, the output end of the first reduction motor 222 drives the worm gear 223 to rotate. The worm gear 223 drives the worm wheel 224 and the first connecting shaft 225 to rotate. One end of the first connecting shaft 225 drives the connecting roller 21 and the second connecting shaft 227 to rotate, thereby winding the polyester mesh around the outer wall of the connecting roller 21. The same method is then used to... The other end of the polyester mesh is fixedly installed on the connecting roller 21 of the second fixing mechanism 3. The output end of the second reduction motor 44 drives the reciprocating screw 45 to rotate. The reciprocating screw 45 drives the positioning block 46 to slide inside the mounting groove 43. While the positioning block 46 is moving, it drives the support frame 41 to move. The two ends of the bottom of the support frame 41 drive the guide block 48 to slide inside the guide groove 47. At the same time, the left side of the support frame 41 drives the first fixing mechanism 2 and one end of the polyester mesh to move through the tension sensor 42 to stretch one end of the polyester mesh, thereby conducting a tension test. The tension sensor 42 detects the tension of the polyester mesh during the tension test and transmits the detected data to the display 7 so that the staff can understand the tension data of the polyester mesh during the tension test.
