Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1, referring to Figures 1-11 As shown: The present invention provides a sewing thread quality detection system, including: a rewinding and unwinding mechanism 1, a detection mechanism 2 is fixedly connected between the opposite sides of the rewinding and unwinding mechanism 1, and a detection component 3 is fixedly communicated with one side of the outer wall of the detection mechanism 2; The detection mechanism 2 includes a mounting frame 21, a gear 221, and a micro cylinder 23; On one side of the outer wall of the gear 221, a moving groove 222 is provided, and on one side of the outer wall of the micro cylinder 23, it is fixedly connected to one side of the outer wall of the gear 221.

[0021] In this embodiment, first, when the device is in use, the sewing thread is wound between the outer walls of one of the two winding rollers 14, and then it is placed between the inner walls of the two sets of detachable bearing seats 133. Subsequently, one end of the sewing thread is inserted between the inner walls of the two inner thread rollers 297. Finally, the sewing thread is wound between the outer walls of the other one of the two winding rollers 14. And when the middle position of the sewing thread passes through the middle position of the detection mechanism 2, the sewing thread will be clamped between the outer walls of the two thread wheels 282. Under the activation of the synchronizer, the two driving motors 131 are kept rotating at the same frequency and in the same direction. The two driving motors 131 can drive the linkage disk A132 to rotate during rotation. Due to the mutual transmission of the linkage disk A132, the transmission belt 142, and the linkage disk B141, the two winding rollers 14 can be driven to rotate independently inside each set of detachable bearing seats 133 respectively, so as to complete the process of winding and unwinding the sewing thread on the outer walls of the two winding rollers 14.

[0022] Embodiment 2, according to Figures 1-2 and Figures 4-11 as shown, the detection mechanism 2 includes a mounting frame 21, a gear 221, and a micro cylinder 23; On one side of the outer wall of the gear 221, a moving groove 222 is provided, and on one side of the outer wall of the micro cylinder 23, it is fixedly connected to one side of the outer wall of the gear 221. A moving block 241 is slidably embedded in the inner wall of the moving groove 222. On one side of the outer wall of the moving block 241, a linkage rod 24 is fixedly installed, and the top of the linkage rod 24 is fixedly connected to the telescopic end of the micro cylinder 23. A transmission plate 25 is movably sleeved on the outer surface of the linkage rod 24. On one side of the outer wall of the transmission plate 25, a rotating groove B251 is provided. A transfer rod 252 is rotatably connected to the inner wall of the rotating groove B251. A long rod 26 is movably sleeved on the outer surface of the transfer rod 252. The bottom of the long rod 26 is fixedly connected to a linkage plate 28. Two inner driving rods 281 are rotatably connected inside the linkage plate 28. Thread wheels 282 are fixedly sleeved on the outer surfaces of the two inner driving rods 281. Two connecting pipes 223 are fixedly communicated with the outer surface of the mounting frame 21. On one side of the outer wall of the mounting frame 21, a driving rotation groove 211 is provided, and the outer surface of the driving rotation rod 22 is rotatably connected inside the driving rotation groove 211. Detection components 3 are fixedly communicated with one side of the outer walls of the two connecting pipes 223. On one side of the inside of the mounting frame 21, a limiting seat 27 is fixedly installed, and the outer surface of the long rod 26 is movably embedded inside the limiting seat 27. Rotating grooves A2231 are provided inside the two connecting pipes 223. Limiting components 29 are rotatably connected to the inner walls of the two rotating grooves A2231. Each of the two groups of limiting components 29 includes a rotating pipe 291. A group of holes 292 are preset inside the two rotating pipes 291. Bearing A293 are fixedly inserted into the inner walls of the two groups of holes 292. Rotating rods 294 are fixedly inserted into the inner walls of the two groups of bearing A293. Annular plates 295 are fixedly connected to one side of the outer walls of the two groups of rotating rods 294. Annular grooves 296 are preset inside the two groups of annular plates 295. Inner wire rollers 297 are rotatably connected to the inner walls of the two groups of annular grooves 296; An annular pipe 301 is fixedly communicated with the inside of the detection component 3. Visual detection devices 302 are fixedly installed on the inner walls of the two annular pipes 301.

[0023] In this embodiment, during this process, since the sewing thread is clamped between the inner walls of two thread wheels 282, subsequently, driven by an external driving device, the driving rod 22 can rotate on its own between the inner walls of the driving groove 211. When the driving rod 22 rotates, it drives the gear 221 to rotate. The transmission plate 25 is rotatably connected between the outer walls of the linkage rod 24. On the other side, the middle transfer rod 252 can also be rotatably connected inside the rotating groove B251. Finally, the long rod 26 is rotatably connected between the outer walls of the middle transfer rod 252 and can maintain a state of being vertically inserted and moving inside the limit seat 27, thereby pulling the component fixed to the bottom of the long rod 26 into an up-and-down linkage state. The two inner driving rods 281 are respectively rotatably connected inside the linkage plate 28, so that the thread wheels 282 fixed to one side of the outer walls of the two inner driving rods 281 can rotate inward. During this process, the two thread wheels 282 and the sewing thread clamped between them can be moved up and down, so as to perform a tensile test on the sewing thread at a certain distance. During this process, when the tensile force of different sewing threads needs to be adjusted, first, the micro cylinder 23 needs to be powered on. When the micro cylinder 23 is in the powered-on state, its output end generates elasticity, thereby pushing the linkage rod 24 to move up and down. The moving block 241 can be inserted and moved inside the moving groove 222 to achieve cooperation, thereby adjusting the diameter position relationship of the linkage rod 24 on the outer wall of the gear 221. The position of the corresponding component moves relatively, so as to adjust the pulling force of the sewing thread clamped between the two thread wheels 282.

[0024] Embodiment Three, according to Figures 1-4 and Figures 10-11 As shown, the winding and unwinding mechanism 1 includes two bottom plates 11. A set of anti-slip pads 111 are fixedly connected to the bottoms of the two bottom plates 11. A set of mounting plates 12 are fixedly installed on the tops of the two bottom plates 11. Threaded mounting rods 121 are fixedly installed on the tops of the two sets of mounting plates 12. An L-shaped fixing plate 15 is fixedly connected between the outer walls of the two sets of mounting plates 12. The outer walls of the two sets of L-shaped fixing plates 15 are fixedly connected to the outer wall of the mounting frame 21. Inner frames 13 are movably sleeved between the two sets of threaded mounting rods 121. Driving motors 131 are fixedly connected to the tops of the two inner frames 13. Linkage disks A132 are fixedly connected to the rotating ends of the two driving motors 131. A set of detachable bearing seats 133 are fixedly installed inside the two inner frames 13. Winding rollers 14 are fixedly inserted into the inner walls of the two sets of detachable bearing seats 133. Linkage disks B141 are fixedly connected to the outer walls of the two winding rollers 14. A transmission belt 142 is drivingly connected inside the linkage disk B141, and the outer wall of the transmission belt 142 is rotatably connected inside the linkage disk A132.

[0025] In this embodiment, during the testing process, both ends of the sewing thread are clamped inside two groups of inner thread rollers 297. When the sewing thread is in a taut state, the positional relationship between the two ends will shift. During this process, since the rotating tube 291 is rotatably connected between the inner surfaces of the rotating groove A2231, the limiting assembly 29 as a whole can be kept in a state of circular rotation. During this process, the two rotating rods 294 can respectively rotate on their own inside the bearings A293. Since the inner thread rollers 297 are rotatably connected inside the annular groove 296, and the two groups of inner thread rollers 297 are also in a meshing rotation state with each other. When the sewing thread clamped between the two groups of inner thread rollers 297 rotates horizontally and vertically, the problem of position deviation at both ends caused by the tension of the sewing thread is reduced. Finally, before the sewing thread is wound up, it will pass through the inside of the detection assembly 3. According to the quality standard and production requirements of the sewing thread, the judgment standard for burrs is set. The sewing thread after the tensile test will be detected, and the test results will be fed back to the production control system. For unqualified sewing threads, the system can send an alarm signal to remind the operator to deal with them.

[0026] The working principle of the whole mechanism is as follows: before using the equipment, the first step is to properly wind and place the sewing thread. The operator needs to wind the sewing thread around the outer wall of one of the two winding rollers 14, and keep the two winding rollers 14 as components for winding and releasing the sewing thread. After the winding is completed, the winding roller 14 with the sewing thread is placed between the inner walls of two sets of detachable bearing seats 133. The detachable bearing seats 133 can not only provide stable rotation support for the winding roller 14, but also facilitate the disassembly and replacement of the winding roller 14 when necessary, thereby improving the maintenance efficiency and flexibility of the equipment. Next, one end of the sewing thread is inserted between the inner walls of the two sets of inner rollers 297. The function of the inner roller 297 is to align the two ends of the sewing thread during the test. The ends are stabilized and guided to ensure that the sewing thread can maintain a stable position and state during the entire test process. Finally, the sewing thread is wound around the outer wall of the other of the two winding rollers 14. At this point, the sewing thread has completed the initial installation in the equipment, forming a complete loop, and is ready for subsequent retraction and tension tests. When the middle position of the sewing thread passes through the interior of the detection mechanism 2, it will be clamped between the outer walls of the two wire wheels 282. The surface of the wire wheel 282 has been specially treated and has good rolling friction, which can ensure that the sewing thread is stably clamped during the test and prevent the sewing thread from slipping or falling off during the test. After completing the installation of the sewing thread, the synchronizer is then started to maintain The two driving motors 131 rotate at the same frequency and in the same direction, so that the sewing thread can be maintained at a certain length during the process of winding and releasing. When the two driving motors 131 start to rotate, the linkage disk A132 will be driven to rotate. The linkage disk A132 can transmit the power of the driving motor 131 to subsequent components. Due to the mutual transmission between the linkage disk A132, the transmission belt 142 and the linkage disk B141, the two winding rollers 14 are finally realized to rotate inside each set of detachable bearing seats 133. This ingenious transmission system design enables the two winding rollers 14 to rotate synchronously and stably, thereby completing the process of winding and releasing the sewing thread on the outer walls of the two winding rollers 14. In this process, The sewing thread flows like a thread between the two winding rollers 14, which provides the necessary conditions for the subsequent tensile test. In the process of reeling and releasing the sewing thread, the tensile test is also carried out synchronously. Since the sewing thread is clamped between the inner walls of the two wire wheels 282, when driven by an external driving device, the driving rod 22 realizes self-rotation between the inner walls of the driving groove 211. When the driving rod 22 rotates, it drives the gear 221 to rotate. The rotation of the gear 221 is transmitted to the linkage rod 24 through the transmission plate 25. The transmission plate 25 is rotatably connected between the outer walls of the linkage rod 24, and the transfer rod 252 on the other side is also rotatably connected to the inside of the rotating groove B251. This connection method ensures the effective transmission of power and the coordinated movement between components. Finally,The long rod 26 is rotatably connected between the outer walls of the transfer rod 252 and can form an up-and-down embedded movement state inside the limit seat 27. The up-and-down movement of the long rod 26 pulls the components fixed to its bottom to perform up-and-down linkage. At the same time, the two inner drive rods 281 are respectively rotatably connected inside the linkage plate 28, so that the thread wheels 282 fixed to one side of their outer walls form an inward self-rotation process. During this process, the two thread wheels 282 and the sewing thread clamped between them are moved up and down, so as to perform a tensile test on the sewing thread between a certain distance. In this way, the tensile force received by the sewing thread during actual use can be accurately simulated, providing reliable data for evaluating the quality of the sewing thread. In actual tests, different sewing threads may require different tensile forces for testing. When the tensile force of different sewing threads needs to be adjusted, first, the micro cylinder 23 needs to be powered on. The micro cylinder 23 is a component for tensile force adjustment. When the micro cylinder 23 is in the powered-on state, its output end generates elasticity, thereby pushing the linkage rod 24 to move up and down. The up-and-down movement of the linkage rod 24 is achieved by the fitting of the moving block 241 moving inside the moving groove 222. This design makes the movement of the linkage rod 24 more stable and accurate, and can accurately adjust its diameter position relationship on the outer wall of the gear 221. As the position of the linkage rod 24 is adjusted, the positions of the corresponding components will also move relatively, and finally, the pulling force between the sewing threads clamped between the two thread wheels 282 is adjusted. In this way, the device can adapt to the tensile test requirements of different types of sewing threads, improving the versatility and applicability of the device. During the test, the two ends of the sewing thread are respectively clamped inside the two groups of inner thread rollers 297. When the sewing thread is in a straightened state, due to the action of the tensile force, the position relationship between the two ends will shift, and this position shift will affect the accuracy of the test results and even cause problems such as the breakage of the sewing thread during the test. To solve this problem, the rotating tube 291 inside the device is rotatably connected between the inner walls of the rotating groove A2231 and can keep the limiting component 29 as a whole in a circular rotation state. During this process, the two groups of rotating rods 294 can respectively generate self-rotation inside the bearing A293. At the same time, the inner thread rollers 297 are rotatably connected inside the annular groove 296, and the two groups of inner thread rollers 297 are in a meshing transmission state with each other, realizing the clamping and transmission of the sewing thread, and also enabling the sewing thread clamped between the two groups of inner thread rollers 297 to rotate horizontally and vertically, thereby reducing the problem of position shift at both ends caused by the tension of the sewing thread. In this way, the device can ensure the stable position of the sewing thread during the tensile test, improving the accuracy and reliability of the test results. In the entire sewing thread production and detection process, when the sewing thread is about to be wound up, it will pass through the inside of the detection component 3. Before that, according to the quality standard of the sewing thread and specific production requirements in advance, when the sewing thread enters the inside of the detection component 3,It will carefully check whether there are burrs on the outer wall of the sewing thread and the specific situation of the burrs. The detection component 3 will quickly feedback the detection result to the production control system. If it is detected that a certain sewing thread does not meet the pre-set standard, that is, there are burrs beyond the allowable range, etc., the system will immediately issue an alarm signal to timely remind the on-site operators to pay attention to the appearance of unqualified products. After receiving the alarm, the operators can handle the unqualified sewing thread according to the actual situation, such as removing it, repairing it or taking other necessary measures to ensure that the sewing thread finally entering the winding link can meet the quality requirements and guarantee the product quality stability of the entire production process.
