[0007] Furthermore, a pigment box is provided in the lower part of the box body, and a pressure box is connected to one side of the pigment box via a one-way valve. A spray pipe is connected to the other side of the pressure box via a one-way valve. A pressure plate is provided inside the pressure box. A receiving tray is provided on the other side of the pressure box body. The pigment box contains water-soluble quick-drying pigment.

[0008] Furthermore, a limiting rod is provided on one side of the pressure plate, and a support wheel is provided on the other end of the limiting rod. Rebound springs are symmetrically arranged on both sides of the support wheel. Pressure contacts are provided on the upper surface of the pressure box, and a pressure block is provided on one side of the bearing bracket of the support wheel.

[0009] Furthermore, the limiting rod and the return spring are both connected to the bearing bracket of the support wheel, and the limiting rod is slidably connected to the pressure box. The support wheel is elastically connected to the pressure box through the return spring, and the bearing bracket of the support wheel is close to the pressure rod.

[0010] Furthermore, lifting rods are symmetrically connected to both sides of the box body, and one end of the lifting rod is connected to a pressure wheel. A fixed wheel is provided below the pressure wheel on one side of the box body, and a scraper is connected to the bearing bracket side of the pressure wheel on the other side of the box body.

[0011] Furthermore, a pad is provided under the pressure wheel on the other side of the box body, and slide rods are symmetrically slidably connected on both sides of the pad. A movable wheel is provided at one end of the slide rod, and a buffer spring is connected in the middle of the bearing frame of the movable wheel.

[0012] Furthermore, the housing has symmetrical sliding frames on both sides of the bearing bracket of the moving wheel, and an airbag is provided in the sliding frame. A slider is connected to one side of the airbag, and the slider is engaged and slidably connected to the sliding frame.

[0013] Furthermore, a fume extraction hood is symmetrically arranged on one side of the housing, and a fume extraction pipe is connected to one side of the fume extraction hood.

[0015] This invention provides an online yarn quality inspection system with the following advantages: During use, the overall strength of the yarn can be tested while visually inspecting it. This strength test prevents yarn breakage and allows marking of areas with substandard strength for later processing. Furthermore, the system removes lint and other debris from the yarn during the inspection process to prevent it from scattering and adhering to the device. It also dries the yarn to prevent the yarn from absorbing moisture from the air during storage, thus avoiding inaccurate strength testing. Additionally, it prevents marking pigments from adhering to the device.

[0016] 1. In the process of visually inspecting yarn through a light panel and camera, the pressure spring can apply pressure to the yarn through the lower pressure wheel, thereby performing overall strength testing on the yarn on the bobbin. This avoids the detection errors that exist in sampling testing. Furthermore, the pressure intensity can be adjusted according to the yarn type before testing to avoid detection errors caused by excessive or insufficient pressure. When the yarn strength is found to be unqualified, the unqualified area can be marked for later processing. After marking, the device can be reset and normal testing can continue.

[0017] 2. When testing yarn, this invention can fix and straighten both sides of the yarn at the strength testing point to avoid testing errors caused by yarn slack. When the yarn strength is found to be unqualified, the fixing of the yarn can be loosened immediately to prevent the yarn from breaking under stress, which would prevent the yarn from continuing to be wound and tested. This ensures the continuity of the testing and winding process and avoids damage to the yarn.

[0018] 3. Before testing, the present invention can remove and collect the lint present on the yarn to prevent the lint from flying and adhering to the device and affecting visual detection. At the same time, the yarn can be dried to prevent the yarn from absorbing moisture from the air when it is placed, which would lead to inaccurate strength testing. After marking the yarn, the pigment can also be dried in time to prevent the pigment from adhering to the device as the yarn moves, which would cause the areas of yarn with qualified strength to be stained with pigment and lead to inaccurate test results.

Detailed Implementation

[0021] Please see Figures 1 to 6 The present invention provides a technical solution: an online yarn quality detection system, comprising a housing 1 and a detection component 2. The detection component 2 is disposed in the middle of the housing 1. The detection component 2 includes a lower pressure wheel 201. The lower pressure wheel 201 is disposed in the middle of the housing 1, and pressure springs 202 are symmetrically connected to both sides of the bearing frame of the lower pressure wheel 201. An adjusting plate 203 is connected to the other end of the pressure springs 202. An electromagnet 204 is connected to the middle of one side of the adjusting plate 203. An adjusting rod 205 is rotatably connected to the middle of the other side of the adjusting plate 203. Limiting rods 206 are symmetrically slidably connected to both sides of the adjusting plate 203. Pressure rods 207 are disposed on both sides of the bearing frame of the lower pressure wheel 201, and connecting rods 208 are connected to both sides of the pressure rods 207. A connecting plate 209 is connected to the other end of the connecting rods 208, and a reset spring 210 is connected to the middle of the connecting plate 209.

[0022] Please see Figures 1 to 4The lower pressure roller 201 is elastically connected to the adjusting plate 203 via a pressure spring 202, and the limiting rod 206 is fixed on the bearing bracket of the lower pressure roller 201. The limiting rod 206 and the connecting rod 208 are slidably connected to the housing 1, and the connecting plate 209 is elastically connected to the housing 1 via a return spring 210. The adjusting rod 205 is threadedly connected to the housing 1. The pressure rod 207 is close to the bearing bracket of the lower pressure roller 201, and a pressure sensor is installed at the close proximity. A light panel and camera for visual inspection are installed at the top inside the housing 1. A pigment box 3 is installed at the bottom inside the housing 1, and a pressure box 4 is connected to one side of the pigment box 3 via a one-way valve. The other side of the pressure box 4 is connected to... There is a spray nozzle 5, and a pressure plate 6 is installed inside the pressure box 4. A receiving tray 7 is installed on the other side of the pressure box 4 in the box body 1. Water-soluble quick-drying pigment is contained in the pigment box 3. A limiting rod 8 is installed on one side of the pressure plate 6, and a support wheel 9 is installed on the other end of the limiting rod 8. Rebound springs 10 are symmetrically arranged on both sides of the support wheel 9. A pressure contact point 11 is installed on the upper surface of the pressure box 4. A pressure contact block 12 is installed on one side of the bearing bracket of the support wheel 9. The limiting rod 8 and the rebound spring 10 are both connected to the bearing bracket of the support wheel 9. The limiting rod 8 is slidably connected to the pressure box 4. The support wheel 9 is elastically connected to the pressure box 4 through the rebound spring 10. The bearing bracket of the support wheel 9 is close to the pressure rod 207. The specific operation is as follows: During the visual inspection of the yarn through the light panel and camera, the pressure spring 202 can apply pressure to the yarn through the lower pressure wheel 201, thereby performing an overall strength test on the yarn on the bobbin, avoiding the detection error that exists in sampling inspection. Before the test, the position of the lower pressure wheel 201 can be adjusted by rotating the adjusting rod 205 according to the yarn model, thereby adjusting the pressure intensity and avoiding detection errors caused by excessive or insufficient pressure. When the yarn strength is found to be unqualified, the lower pressure wheel 201 can drive the support wheel 9 to descend under the action of the pressure spring 202, and then drive the pressure plate 6 through the limiting rod 8 to spray the pigment in the pressure box 4 onto the yarn, marking the unqualified parts for later processing. After the marking is completed, the device is reset and normal inspection can continue.

[0023] Please see Figures 1 to 2 and Figures 4 to 6Inside the housing 1, lifting rods 13 are symmetrically connected on both sides, and one end of each lifting rod 13 is connected to a pressure wheel 14. A fixed wheel 15 is installed below the pressure wheel 14 on one side of the housing 1, and a scraper 16 is connected to one side of the bearing bracket of the pressure wheel 14 on the other side of the housing 1. A pad 17 is installed below the pressure wheel 14 on the other side of the housing 1, and sliding rods 18 are symmetrically slidably connected to both sides of the pad 17. A movable wheel 19 is installed at one end of the sliding rod 18, and a buffer spring 20 is connected to the middle of the bearing bracket of the movable wheel 19. Sliding frames 21 are symmetrically arranged on both sides of the bearing bracket of the movable wheel 19 on the housing 1, and an airbag 22 is installed inside the sliding frame 21. A slider 23 is connected and is engaged and slidably connected to a sliding frame 21. A suction hood 24 is symmetrically arranged on one side of the housing 1, and a suction pipe 25 is connected to one side of the suction hood 24. An air pump 26 is connected to the side of the suction pipe 25 away from the suction hood 24 through a pipe, and a heater 27 is connected to the air pump 26 through a pipe. An air outlet pipe 28 is arranged on one side of the heater 27, and an air outlet hood 29 is arranged at one end of the air outlet pipe 28. A filter is arranged near the air pump 26 on the suction pipe 25, and an air bag 22 is connected to the suction pipe 25 and the air outlet pipe 28 through pipes and a solenoid valve respectively. The suction pipe 25 is C-shaped, and the air outlet pipe 28 is F-shaped. The specific operation is as follows: When testing the yarn, the lifting rod 13 drives the pressure roller 14 to descend, allowing the pressure roller 14, in conjunction with the fixed roller 15 and the moving roller 19, to fix and taut both sides of the yarn at the strength testing point, avoiding testing errors caused by yarn slack. When the yarn strength is found to be unqualified, the air in the airbag 22 can be immediately extracted through the air extraction pipe 25, causing the slider 23 to release the restriction on the moving roller 19, allowing the moving roller 19 to loosen its fixation on the yarn and move with the yarn, preventing the yarn from breaking under stress and thus ensuring the continuity of the testing and winding process, and avoiding damage to the yarn. After marking is completed, the moving roller 19 can also be used in the buffer spring. The spring 20 automatically resets the device, facilitating continued testing. Before testing, the moving wheel 19 and the pressure wheel 14 on the same side can remove lint from the yarn, and the air pump 26 collects the lint to prevent it from flying and adhering to the device, affecting visual inspection. The air pumped out by the air pump 26 is heated and then sent back into the device through the air outlet pipe 28 to dry the yarn, preventing the yarn from absorbing moisture from the air when placed, which would lead to inaccurate strength testing. After marking the yarn, the heated air in the air outlet pipe 28 can also dry the pigment on the yarn in time, preventing the pigment from adhering to the device as the yarn moves, causing the area with qualified yarn strength to be stained with pigment, resulting in inaccurate test results.

[0024] In summary, when using this online yarn quality inspection system, firstly, adjust the height of the adjusting plate 203 by rotating the adjusting rod 205 on the housing 1 according to the yarn type. When the adjusting plate 203 moves, the limiting rod 206 can restrict it through the housing 1 to prevent the adjusting plate 203 from tilting and causing uneven force on the yarn by the pressure roller 201, which could lead to yarn breakage during inspection. After adjustment, pull out the yarn end from the yarn package, pass it through the opening on the left side of the housing 1, and then pass it through the housing 1 in sequence above the moving wheel 19, support wheel 9, and fixed wheel 15. After leaving the housing 1 through the opening on the right side of the housing 1, it is fixed on the winding machine. The lifting rod 13 drives the pressure roller 14 to descend, which, together with the fixed wheel 15 and the moving wheel 19, presses the yarn on both sides of the pressure roller 201. Start the device and winding machine, and the light panel and camera inside the housing 1 can perform visual inspection of the yarn during the winding process. During the visual inspection process, the pressure spring 202 can apply pressure to the yarn through the pressure roller 201 to test the yarn strength. At the same time, the air pump 26 can extract the air from the box 1 through the air extraction pipe 25 and the air extraction hood 24, thereby removing the lint adhering to the yarn along with the air, preventing the lint from adhering to the light board or camera and affecting the accuracy of the visual inspection. The scraper 16 can scrape off the lint on the pressure roller 14 and remove it along with the air during the air extraction. The filter on the air extraction pipe 25 can prevent lint from entering the air pump 26. The air extracted by the air pump 26 is heated by the heater 27 and then sent back to the box 1 through the air outlet pipe 28 to dry the yarn, preventing the yarn from absorbing free moisture in the air after long-term storage, which would cause changes in its strength. When the yarn strength is unqualified, the lower pressure roller 201 will descend under the action of the pressure spring 202 and apply force to the pressure rod 207. When the pressure sensor on the pressure rod 207 detects the pressure rise, it immediately opens the solenoid valve on the air bag 22 and the air extraction pipe 25, so that the air in the air bag 22 can be extracted from the air extraction pipe 25, thereby driving the slider 23 to slide into the slide frame 21, releasing the restriction of the slider 23 on the bearing frame of the moving wheel 19. The lower pressure roller 201 can then drive the pressure rod 207 to descend. The connecting rod 208 drives the connecting plate 209 to descend along with the pressure rod 207 and compresses the return spring 210. This causes the pressure rod 207 to drive the moving wheel 19 to descend synchronously and compress the buffer spring 20, releasing the pressure of the moving wheel 19 and the pressure roller 14 on the yarn, allowing the yarn to enter the housing 1 faster as the lower pressure roller 201 descends, avoiding yarn breakage when the lower pressure roller 201 descends. The slide rod 18 can restrict the moving wheel 19 through the pad 17 to prevent it from deflecting. When the pressure roller 201 descends, the support roller 9 can be pressed down simultaneously by the pressure rod 207, and the return spring 10 can be compressed. When the support roller 9 descends, the pressure plate 6 can be driven to descend in the pressure box 4 by the limiting rod 8, so that the pigment in the pressure box 4 can be sprayed onto the yarn through the spray pipe 5 to mark the parts of the yarn that are not up to standard in terms of strength. The hot air in the air outlet pipe 28 can be sprayed onto the dyed yarn through the air outlet hood 29 to dry the pigment. The water-soluble quick-drying pigment can ensure that it dries quickly without damaging the yarn, and avoids the pigment adhering to the pressure roller 14 and the fixed roller 15, which is difficult to clean. It can also prevent other parts of the yarn from being stained with pigment, which would cause the marking to be inaccurate. The limiting rod 8 can prevent the support roller 9 and the pressure plate 6 from shifting when moving. The receiving tray 7 can receive the pigment dripping from the yarn and prevent the pigment from dripping onto the inner wall of the box 1. When the pressure block 12 contacts the pressure contact point 11, marking is complete. The electromagnet 204 is energized, attracting the lower pressure roller 201 and causing it to rise. The connecting plate 209, under the action of the buffer spring 20, drives the pressure rod 207 to reset via the connecting rod 208. After the pressure rod 207 is removed, the moving wheel 19 and the support wheel 9 reset under the action of the buffer spring 20 and the return spring 10, respectively. When the support wheel 9 drives the pressure plate 6 to rise, it draws pigment from the pigment box 3 into the pressure box 4 for replenishment, facilitating marking on the lower side. When the pressure rod 207... After the pressure sensor detects that the pressure has recovered, it immediately opens the solenoid valve on the pipe connecting the airbag 22 and the air outlet pipe 28 and closes the solenoid valve on the pipe connecting the airbag 22 and the air extraction pipe 25, so that the airflow in the air outlet pipe 28 can enter the airbag 22, causing it to expand and push the slider 23 out of the slide frame 21, so that the slider 23 restricts the moving wheel 19 to prevent the moving wheel 19 from falling again. At the same time, the electromagnet 204 is de-energized. As the winding machine continues to wind, the yarn can be straightened and tightened again in the housing 1, and the pressure roller 201 can apply force to the yarn again to detect its strength.
