Description

Technical Field

[0001] This utility model relates to the field of yarn winding detection technology, specifically a yarn winding tightness detector. Background Technology

[0002] In the textile industry production process, the tightness of yarn winding is a core parameter that directly affects the stability of subsequent weaving and dyeing processes and the quality of the final textile products. If the winding is too loose, the yarn is prone to loosening and knotting during storage or unwinding, affecting production efficiency. If the winding is too tight, the yarn will be in a stretched state for a long time, causing problems such as fiber breakage and reduced yarn elasticity, which in turn leads to fabric defects.

[0003] Application number "CN201721798972.5" discloses a textile yarn tensioning device, including a housing. A first conveying roller, a second conveying roller, and a third conveying roller are movably installed from left to right in the middle of the inner cavity of the housing. An electric telescopic rod is fixedly installed at the left end of the bottom of the inner cavity of the housing, and a support plate is fixedly connected to the top of the electric telescopic rod. A sleeve is fixedly connected to the middle of the top of the support plate, and a first support rod is movably connected to the middle of the bottom of the sleeve through a spring. This invention features an electric telescopic rod fixedly installed at the left end of the bottom of the housing cavity. Through the action of a support plate, sleeve, spring, first support rod, and tension wheel, the yarn tension can be adjusted. Simultaneously, through the action of a pressure sensor, second support rod, and pressure testing wheel, the yarn tension can be automatically detected, and the telescopic length of the electric telescopic rod can be automatically adjusted according to the yarn tension, achieving the purpose of automatically adjusting the yarn tension. However, a drawback is that during the tensile testing stage, the yarn is prone to localized loosening and fiber slippage due to the lack of effective limiting and fixing structures, and may even detach from the surface of the conveyor roller or tension wheel, causing fluctuations in tension data during testing and directly affecting the accuracy and stability of the tensile results.

[0018] By installing the positioning and anti-detachment component 3 on the device, the positioning and anti-detachment component 3 can ensure the tightness of the yarn fixation during the pressing process and prevent the yarn from detaching, thus ensuring the stability of the testing process.

[0019] The bracket assembly 1 includes a mounting base plate 101. A support back plate 102 is fixedly mounted on the top rear side of the mounting base plate 101. Extending horizontal plates 103 are fixedly mounted on both sides of the top of the support back plate 102. A mounting top plate 105 is fixedly mounted on the top of the support back plate 102. Limiting grooves 104 are evenly provided in the middle of both the extending horizontal plates 103 and the support back plate 102. The mounting base plate 101 provides bottom support for all components. The support back plate 102, the extending horizontal plates 103, and the mounting top plate 105 form a three-dimensional mounting frame. The limiting grooves 104 on the extending horizontal plates 103 and the support back plate 102 can limit the sliding trajectory of the limiting slide rod 1 205 and the limiting slide rod 207 in the transmission tension assembly 2, ensuring stable movement of the components.

[0020] The transmission stretching assembly 2 includes a rotary motor 201, which is fixedly mounted on the top of the mounting plate 105. A three-axis transmission device 202 is fixedly mounted on the bottom of the rotary motor 201.

The end of the limiting slide rod 205 is slidably installed inside the limiting groove 104 of the extension plate 103. Power transmission and position adjustment are realized by the transmission tension assembly 2. After the rotary motor 201 is started, the power is transmitted to the threaded rods 203 on both sides and the bottom threaded rod 206 through the three-axis transmission device 202. When the threaded rod 203 rotates, it drives the outer threaded block 204 to move along the trajectory formed by the limiting slide rod 205 and the limiting groove 104, thereby driving the positioning anti-detachment assembly 3 to rise and fall. When the threaded rod 206 rotates, it drives the threaded block 208 to move along the trajectory formed by the limiting slide rod 207 and the limiting groove 104, thereby realizing the rising and falling of the extrusion head 209.

[0021] The placement slot assembly 4 includes a positioning bracket 401, which is fixedly installed on the top two sides of the mounting base plate 101. An elastic bracket 402 is fixedly installed at the top middle of the positioning bracket 401. A positioning clamping ball 403 is fixedly installed at the top of the elastic bracket 402.

[0022] A limiting groove 4031 is provided in the middle of the top of the positioning clamp ball 403. When the positioning anti-detachment component 3 descends, the positioning protrusion 303 on the inner wall of the anti-detachment pressure cover 302 is embedded in the limiting groove 4031. At the same time, the extension pressure block 304 on the inclined bending rod 301 presses down the pressing plate 405. The elastic bracket 402 is finely adjusted by the brake rocker plate 404, so that the positioning clamp ball 403 clamps the yarn and prevents the yarn from falling off or shifting during the test.

[0023] The detection component 5 includes a limiting side plate 501. The two limiting side plates 501 are fixedly installed in the middle of the front outer wall of the support back plate 102. A detection tray 502 is correspondingly provided in the middle of the limiting side plate 501. Yarn is correspondingly provided on the top of the detection tray 502. The bottom of the detection tray 502 is fixedly installed on the top of the detection device 504 through a force spring 503. A display screen 505 is fixedly installed on the front of the detection device 504. The detection device 504 is fixedly installed in the middle top of the mounting base plate 101. The detection component 5 senses the stress state of the yarn. The detection tray 502 of the detection component 5 receives the stretched yarn. Different yarn tension will generate different downward pressure. The pressure is transmitted to the bottom force spring 503 through the detection tray 502. The deformation degree of the force spring 503 changes with the pressure. The detection device 504 senses the pressure value corresponding to the spring deformation and displays the detection result on the display screen 505 to realize the detection of yarn winding tension.

[0024] This yarn winding tightness detector is supported by a bracket assembly 1, in which the mounting base plate 101 provides bottom support for all components. The support back plate 102, the extension cross plate 103, and the mounting top plate 105 form a three-dimensional mounting frame. The limiting grooves 104 on the extension cross plate 103 and the support back plate 102 can limit the sliding trajectory of the limiting slide rod 205 and the limiting slide rod 207 in the transmission tension assembly 2, ensuring stable component movement. At the same time, the transmission tension assembly 2 is used to realize power transmission. The power is transmitted to the two threaded rods 203 on both sides and the bottom threaded rod 206 through the three-axis transmission device 202 after the rotary motor 201 starts. When the threaded rod 203 rotates, it drives the outer threaded block 204 to move along the trajectory formed by the limiting slide rod 205 and the limiting slide groove 104, thereby driving the positioning and anti-detachment component 3 to rise and fall. When the threaded rod 206 rotates, it drives the threaded block 208 to move along the trajectory formed by the limiting slide rod 207 and the limiting slide groove 104, thereby achieving the desired position adjustment. The extrusion head 209 is raised and lowered; and in conjunction with the positioning and anti-loosening component 3 and the placement groove component 4, the yarn is positioned and fixed. The top limiting groove 4031 of the positioning clamping ball 403 of the placement groove component 4 is used to place the yarn. When the positioning and anti-loosening component 3 descends, the positioning protrusion 303 on the inner wall of the anti-loosening pressure cover 302 is embedded in the limiting groove 4031. At the same time, the extension pressure block 304 on the inclined bending rod 301 presses down the pressing plate 405. The brake rocker plate 404 drives the elastic bracket 402 to make a slight adjustment, so that the positioning clamping ball 403 clamps the yarn. Tighten the yarn to prevent it from falling off or shifting during testing; finally, the stress state of the yarn is sensed by the detection component 5. The detection tray 502 of the detection component 5 supports the stretched yarn. Different yarn tension will generate different downward pressure. The pressure is transmitted through the detection tray 502 to the bottom force spring 503. The deformation degree of the force spring 503 changes with the pressure. The detection device 504 senses the pressure value corresponding to the spring deformation and displays the detection result on the display screen 505 to realize the detection of yarn winding tightness.In the workflow, initial preparation is first performed, checking the equipment status to ensure that the mounting base 101 of the support assembly 1 is placed stably, the display screen 505 of the detection assembly 5 is started normally, and the rotary motor 201 of the transmission tension assembly 2 is in a power-off standby state. Then, the two ends of the yarn to be tested are placed in the top limiting grooves 4031 of the positioning clamping balls 403 of the two side placement groove assemblies 4, while the middle section of the yarn is placed on top of the detection tray 502 of the detection assembly 5, ensuring that the yarn is naturally stretched and without wrinkles. Next, the yarn positioning and fixing stage begins. The rotary motor 201 of the transmission tension assembly 2 is started, and the power is transmitted to the threaded rods 203 on both sides through the three-axis transmission device 202. The rotation of the threaded rods 203 drives the threaded blocks 201. 4. The limiting slide bar 205 moves downward along the limiting slide groove 104 of the extension horizontal plate 103. The threaded block 204 drives the inclined bending rod 301 of the positioning anti-detachment component 3 to descend synchronously until the anti-detachment pressure cover 302 is fastened to the outside of the positioning clamping ball 403 and the positioning protrusion 303 is fully embedded in the limiting groove 4031, initially fixing both ends of the yarn. During the continued descent, the extension pressure block 304 on the inclined bending rod 301 contacts and presses down the pressing plate 405 of the placement groove component 4. The pressing plate 405 rotates around the reset shaft 406, and the elastic bracket 402 is slightly deformed by the brake rocker 404, so that the positioning clamping ball 403 further clamps the yarn, completing the positioning and fixing. Then, the yarn stretching and testing stage begins, and the rotary motor 20 1. During continuous operation, the three-axis transmission device 202 simultaneously drives the bottom threaded rod 206 to rotate. The threaded rod 206 drives the threaded block 208 to move downward along the limiting slide bar 207 and the limiting slide groove 104 of the support back plate 102. The threaded block 208 drives the extrusion head 209 to descend until the extrusion head 209 contacts and presses down on the yarn on the detection tray 502, putting the yarn in a stretched state. At this time, the tension of the yarn is transmitted to the bottom force spring 503 through the detection tray 502. The force spring 503 generates a corresponding deformation. The detection device 504 of the detection component 5 senses the deformation pressure of the force spring 503 in real time, converts the pressure signal into yarn tension data, and displays the detection results on the display screen 505. Pressure values, tightness levels, etc.; finally, the test ends and resets. After the test is completed, the rotary motor 201 is turned off, and the three-axis transmission device 202 is controlled to rotate in reverse, driving the threaded rod 1 203 and threaded rod 206 to rotate in reverse, causing the threaded block 1 204 and threaded block 208 to drive the positioning anti-detachment component 3 and the extrusion head 209 to rise and reset respectively. After the positioning anti-detachment component 3 rises, the extension pressure block 304 disengages from the pressure plate 405, and the pressure plate 405 resets under the action of the reset shaft 406. The elastic bracket 402 returns to its original state, the positioning clamp ball 403 releases the yarn, the yarn after testing is removed, the surface of the test tray 502 is cleaned, and the display screen 505 of the test device 504 is turned off, completing a single test process.
