After the adjusting arm moves for a certain distance and then continues to move, the convex rod on it enters the inclined groove of the displacement plate in the water discharge assembly. With the movement of the adjusting arm, the displacement plate moves outward, and the blocking block is pulled by the adjusting rod to move, canceling the blockage inside the shell, compressing the extrusion spring, allowing water resources to enter the water outlet, and then poured into the distribution pipe of the pipeline body, thereby distributed to multiple water storage tanks, to realize the weight-added strength test of multiple sewing threads; Step 7: Data collection.

[0017] In the strength testing mechanism, the strength of the sewing thread is tested by adjusting the weight using water resources. With the precise infusion of water resources, the sewing thread is suspended until it breaks, thereby testing the actual strength of the sewing thread. In addition, the water resource configuration method can be used to test a variety of different types of sewing threads during actual operation, further improving the applicability of sewing thread testing.

[0018] The cooperation of the wire harness mechanism and the fine-tuning component realizes the partition fixation of the sewing threads to be tested, so that the sewing threads can be synchronously tested for wear resistance and color fastness under the action of the driving component, thereby optimizing the equipment structure while ensuring the accuracy of sewing thread detection, reducing the trouble of sewing thread detection, alleviating the burden on staff and improving detection efficiency.

[0019] The configuration of multiple fine-tuning components can realize the adjustment of the tension of different sewing threads to be tested, so as to ensure the uniformity of the tension of multiple sewing threads to be tested during testing, achieve the consistency of the environmental conditions of multiple sewing threads during unified testing, and further ensure the accuracy of sewing thread testing.

[0020] The configuration of the drive assembly not only realizes the drive adjustment of the detection assembly in the wiring harness mechanism, but also adjusts the switch of the water release assembly in the strength detection mechanism, thereby simultaneously realizing the strength test, wear resistance test and color fastness test of the sewing thread under the setting of a single drive structure, simplifying the equipment structure, reducing the production cost of the product, and further facilitating the promotion and use of the equipment.

[0055] The present invention provides a detection method for a sewing thread quality detection device, the method comprising the following steps: Step 1: Wire reel wiring, insert the wire reel to be tested on the supporting member 22 in the wire carrying assembly 2, and pull out the thread end. Then the sewing thread pulled out from the wire reel passes over the round roller 23 and passes through the wire harness mechanism 4, and the sewing thread passes through the slot of the supporting column 51 in the corresponding fine-tuning assembly 5. When the sewing thread passes through the wire harness mechanism 4, it is arranged in a straight line according to the current position of the wire reel, avoiding the problem of misalignment after the sewing thread is arranged.

[0056] After leaving the harness mechanism 4, the sewing thread enters the strength detection mechanism 3. After passing the steering member 32 from below, it bypasses the steering wheel 333 in the detection member 33 at the corresponding station and is then bound to the corresponding water storage tank 332. The operation is repeated to complete the wiring operation of multiple sewing threads on the product. After the wiring operation is completed, the sewing thread is tightened by rotating the wire coil to avoid a large degree of slack in the sewing thread after wiring.

[0057] Step 2: Fixing of sewing threads: by adjusting the worm 410 in the cable tie mechanism 4, the worm wheels 414 in the two fixing components 41 rotate synchronously. This drives the corresponding screw 412 to move, so that the multiple clamping blocks 413 thereon are displaced, and the multiple sewing threads passing through the cable tie mechanism 4 are clamped and fixed accordingly. The clamping and fixing of the sewing threads by the two fixing components 41 ensures the tension of the sewing threads in the strength detection area and the cable tie mechanism 4 area.

[0058] The movement of the clamp block 413 causes the detection assembly loaded thereon to move upward synchronously, and then the friction plate 47 and the sponge plate 48 in the detection assembly contact the sewing thread to be tested respectively. The plug block 492 in the splicing piece 49 is synchronously plugged into the plug sleeve 63 in the driving assembly 6.

[0059] Step 3: Adjust the tension of the sewing thread. According to the tension of the sewing thread on the corresponding supporting column 51, cover the corresponding cap 52 on the supporting column 51. The downward movement of the cap 52 adjusts the tension of the sewing thread so that the sewing thread is in a horizontal state when contacting the friction plate 47 and the sponge plate 48. After the tension of the sewing thread is adjusted, the threaded rod 53 is used to realize the limit locking between the supporting column 51 and the cap 52.

[0060] Step 4: Standard weight for sewing thread strength test: configure the minimum weight standard for strength test according to the model of the sewing thread to be tested. Start the water pump body 342 of the water distribution component 34 in the strength test mechanism 3 through the external controller, and open the second electric control valve. After the water resources in the water tank 341 are pumped out, they are evenly distributed to the water storage tank 332 in the corresponding test piece 33 through the pipeline body 343 to form the minimum weight. After the weight is completed, close the second electric control valve.

[0061] Step 5: Adjust the amount of water resources added. According to the model of the sewing thread to be tested, the water outlet head 3446 used to increase the load is switched and adjusted. Loosen the limit bolt, rotate and adjust the water collecting cover 34461 so that the corresponding water discharge pipe 34462 distributed at the bottom corresponds to the material guide pipe. Then tighten the limit bolt again to achieve the limit locking of the water outlet head 3446.

[0062] Step 6: Sewing thread testing, the cylinder body 61 in the driving assembly 6 is turned on by an external controller, and the adjusting arm 62 performs reciprocating lateral motion. The adjusting arm 62 drives the splicing piece 49 to move through the plug sleeve 63, and then the friction plate 47 and the sponge plate 48 to move synchronously through the sliding sleeve 46, so as to achieve the wear resistance test and color fastness test of the sewing thread.

[0063] When the adjusting arm 62 moves for a certain distance and then continues to move, the protruding rod on it enters the inclined groove of the displacement plate 3444 in the water discharge assembly 344. As the adjusting arm 62 moves, the displacement plate 3444 moves outward. The blocking block 3442 is pulled by the adjusting rod 3443 to move, cancel the blockage inside the shell 3441, and compress the extrusion spring. The water resources enter the water outlet 3446 and then pour into the distribution pipe 3432 of the pipeline body 343. Thus, it is distributed to multiple water storage tanks 332, realizing the weight-added strength test of multiple sewing threads.

[0064] Step 7: Data collection, the above steps are repeated until the sewing thread bound to the water tank 332 breaks and the device stops running. Thus, the strength, wear resistance and color fastness of the sewing thread are recorded according to the current water weight in the water tank 332, the degree of wear of the sewing thread and the color of the sponge board 48. After the recording is completed, the device is turned on again until all the sewing threads arranged on it break.

[0065] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
