[0002] In industrial production, conveyor belts are widely used as an important material conveying and connecting tool in warehousing, logistics, and other fields. However, conveyor belts often face the risk of tearing during use, especially during conveying. Tearing accidents are prone to occur due to foreign objects in the material, belt aging, improper operation, and other reasons.

[0003] In traditional tape tear resistance testing, the tensile force changes rapidly at the moment the tape breaks, which may make it impossible to record the peak tensile force data of the tape in a timely and accurate manner. During the tape tensile test, if the tape is not firmly fixed, it is easy to loosen during the pulling process, thus affecting the accuracy of the test and failing to truly reflect the tear resistance performance of the tape.

[0004] Therefore, existing technologies have problems with inaccurate and untimely data recording and unstable tape fixation when detecting tape tears. Utility Model Content

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5This utility model provides an embodiment of a tape tear resistance testing device, including a workbench 1; it also includes a photoelectric sensor 210 and a take-up roller 305. A slider 201 is slidably disposed on the upper end of the workbench 1. The upper end of the slider 201 is provided with a plurality of first sliding grooves 205 for subsequent height adjustment. A limit post 207 is provided in the first sliding groove 205. The photoelectric sensor 210 is disposed above the limit post 207. Two first fixing plates 103 are fixedly connected to the upper end of the workbench 1. A first groove 104 is opened through the two first fixing plates 103 at their close ends. A tape fixing component is provided on the first fixing plate 103 at the rear end of the workbench 1. The tape fixing component includes a threaded cylinder 403. A take-up force measuring component is provided on the first fixing plate 103 at the front end of the workbench 1. The take-up force measuring component includes a first fixing frame 3. A first rotating disk is rotatably disposed at the front end of the first fixing frame 3. 302, multiple support bars 303 are fixedly connected to the left end of the first rotating disk 302, and a winding wheel 305 is fixedly connected to the left end of the support bars 303. A steel rope 307 is connected to the winding wheel 305. A tension sensor 308 is set at the upper end of the workbench 1. The upper end of the tension sensor 308 and the other end of the steel rope 307 are fixedly connected to each other. First, the tape is put onto the tape fixing component. Then, the tape is passed through the two first grooves 104 and placed on the support bars 303 for fixing. Then, the first rotating disk 302 is rotated. When rotating, the winding wheel 305 is wound up. At the same time, the tension sensor 308 calculates the force of the winding wheel 305 when it is winding up by pulling the steel rope 307. When the tape is torn, the peak value of the tension on the tension sensor 308 is retained by the change of the photosensitive signal at the upper end of the photoelectric sensor 210. The peak value of the tape's tear resistance is obtained by multiple sets of experiments.

[0023] Please see Figures 1-2In this embodiment, a slide rail 2 is fixedly connected to the upper end of the workbench 1, and a slide groove 202 is provided at the lower end of the slider 201. The slide groove 202 is adapted to the slide rail 2. A first sliding groove 205 is provided at the four corners of the slider 201. A through-type limiting tube 206 is provided at the upper end of the slider 201, and a flow hole 203 is provided at the front end of the slider 201. The flow hole 203 and the limiting tube 206 are interconnected. A rubber column 208 is provided inside the limiting tube 206. A second fixing plate 209 is fixedly connected to the lower end of the photoelectric sensor 210. The lower end of the second fixing plate 209 is connected to the rubber column 208. The upper end of 8 and the upper ends of the four limiting posts 207 are fixedly connected to each other. The left end of the slider 201 is fixedly connected to the handle 204. The processor 101 is provided on the worktable 1. The lower end of the first fixed plate 103 at the front end of the worktable 1 is provided with a second groove 105. The photoelectric sensor 210 and the tension sensor 308 are connected by an electrical signal through the processor 101. The photoelectric sensing signal on the photoelectric sensor 210 fluctuates (the model of the photoelectric sensor 210 is LR-X series). After passing through the processor 101, the value on the tension sensor 308 is quickly recorded.

[0024] Please see Figures 3-5 In this embodiment, a second fixing bracket 4 is fixedly connected to the rear end of the first fixing plate 103 on the tape fixing component. A second rotating disk 401 is fixedly connected to the rear end of the second fixing bracket 4. The left end of the second rotating disk 401 and the right end of the threaded cylinder 403 are fixedly connected to each other. A stud 404 is threadedly installed on the left end of the threaded cylinder 403. A third rotating disk 405 is fixedly connected to the left end of the stud 404. An extension rod 406 is fixedly connected to the left end of the third rotating disk 405. A first rubber pad 402 is fixedly connected to the left end of the second rotating disk 401. A second rubber pad 407 is fixedly connected to the right end of the third rotating disk 405. The tape on the threaded cylinder 403 is fixed by the mutual proximity between the first rubber pad 402 and the second rubber pad 407. A first fixing bracket 3 is fixedly connected to the front end of the first fixing plate 103 on the winding force measuring component. A servo motor 301 is provided at the right end of the first fixed frame 3. The output shaft of the left end of the servo motor 301 passes through the first fixed frame 3 and is connected to the right end of the first rotating disk 302. A fixing strip 306 is fixedly connected to the front end of the first fixed plate 103 at the front end of the worktable 1. The left end of the winding wheel 305 is limited to rotation on the fixing strip 306. A third groove 304 is provided through part of the support strip 303 on the first rotating disk 302. By inserting the end of the tape into the third groove 304 and rotating the support strip 303, the tape is fixed. Two triangular support frames 102 are provided at the ends of the two first fixed plates 103 that are far apart from each other. The triangular support frames 102 can strengthen the connection strength of the two first fixed plates 103 on the worktable 1, thereby preventing deformation.

[0025] First, the tape is placed inside the threaded cylinder 403. Then, the tape is pulled out, passed through the two first grooves 104, and placed in the third groove 304 on the support bar 303 for winding. Next, by rotating the extension rod 406, the threaded structure formed by the threaded cylinder 403 and the stud 404 clamps the tape on both sides of the threaded cylinder 403 with the first rubber pad 402 and the second rubber pad 407. This prevents the tape from loosening during the pulling process, which could lead to inaccurate measurements. Then, the slider 201 is slid on the slide rail 2, and the second fixing plate 209 is fixed by pulling it up and down. (Simple friction fixing can be achieved through the friction between the rubber surface of the rubber column 208 and the limiting tube 206, and the limiting tube 206 is conveniently fixed through the flow hole 203.) (The gas located below the rubber column 208 can be smoothly discharged) By turning on the servo motor 301, the first rotating disk 302 is rotated, thereby winding the tape through the support bar 303 (the tape fixing parts are loosened during the winding process). Then, the processor 101 tare and zeroes the data on the tension sensor 308. Then, by turning on the servo motor 301 again, the support bar 303 pulls the tape, and the winding wheel 305 winds up the steel rope 307. When the tape tears, the photoelectric sensing signal on the photoelectric sensor 210 (the photoelectric sensor 210 is an LR-X series) fluctuates. After the processor 101, the value on the tension sensor 308 is quickly recorded. Through multiple experiments, the peak force of the overall tear of the tape is obtained.
