Description

Technical Field

[0001] The present invention relates to the field of new material testing equipment, and particularly to a yarn softness detection device and a detection method. Background Art

[0002] In the textile industry, the softness of yarn is a key indicator determining the quality of textiles. With the wide application of new textile material yarns such as high-performance synthetic fibers, functional nanomaterials, and environmentally friendly recycled materials, traditional detection technologies are facing severe challenges. New material yarns have unique microscopic structural characteristics (such as nanoscale fiber diameters, porous structures, composite interfaces) and dynamic mechanical properties (such as viscoelasticity, time-temperature effect, anisotropy). The detection of their softness requires breaking through the limitations of traditional methods. In the prior art, the manual feel evaluation method cannot perceive the surface energy effect of nanomaterials, the bending test method is difficult to simulate the dynamic deformation of intelligent response materials, the friction detection lacks sensitivity to super-slippery coating materials, and the compression test cannot characterize the energy absorption characteristics of porous structures. In particular, new material yarns are prone to introducing nanoscale impurity particles (such as catalyst residues, environmental aerosols) during the production process, and traditional equipment lacks a cleaning mechanism for microscopic pollutants, resulting in distorted detection data. In addition, functional treatments (such as antibacterial coatings, conductive modification) may change the surface friction characteristics of the yarn, and traditional single-parameter detection cannot analyze the softness performance under the coupling action of multiple physical fields. Therefore, we propose a yarn softness detection device and a detection method to meet the detection requirements of new material yarns and solve the above-mentioned problems.

[0013] Preferably, a method for detecting the softness of yarns includes the following detection steps:

[0014] S1. Put the small sample of the yarn to be detected on the clamping post. Then lead out one end of the yarn and pass it through the yarn guide roller. Further guide the yarn into the yarn detector through the yarn guide roller. Then drive the fixed bin to rotate by the motor using the fixed shaft. When the fixed bin rotates, press down the yarn passing through the lower part through the pressing plate. Take a picture of the compressed state of the yarn through the industrial camera arranged on one side beside, and obtain the compression rate of the yarn to realize the detection of the softness of the yarn. Realize continuous compression detection during the yarn introduction through the rotation of the fixed bin;

[0015] S2. Through the pressure adjustment of the pressing plate, realize the detection of the compression amount of the yarn under different pressures. During the rotation of the fixed shaft, drive the driving gear meshed on one side to perform synchronous detection through the driven gear on the outer periphery of the fixed shaft. Drive the guiding belt to rotate integrally through the driving gear using the meshing teeth meshed with it. Further guide the yarn through the guiding belt. The end of the yarn will droop naturally after passing through the moving wheel. At this time, take a picture and measure the yarn through the optical camera.

[0016] S3. During detection, the operation of the electric push rod drives the first carriage to move, and the first carriage drives the moving wheels to move synchronously, thereby realizing the adjustment of the ratio between the supported length and the sagging length of the yarn, and obtaining the bending amplitude range and average value of the yarn under different supported lengths and sagging lengths.

[0017] S4. When the sagging yarn is detected by the optical camera, the operation of the threaded rod drives the optical camera to move up and down, so that when the sagging length of the yarn changes, the optical camera moves along with the yarn, realizing the follow-up detection of the softness of this section of the yarn.

[0018] S5. During the softness detection of the yarn, the operation of the air pump uses the air extraction port to extract the surrounding gas, thereby cleaning the yarn on the guiding belt through the through port. At the same time, the cleaning roller inside the guiding belt cleans the guiding belt to prevent dust from sticking to the yarn subsequently. Meanwhile, the gas is discharged from the inside of the transfer bin through the air outlet pipe, and the air flow impacts the inside of the connecting cover to clean the guiding belt.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention can realize the downward pressing of the yarn passing through the lower part through the pressing plate, and can realize the shooting of the compressed state of the yarn through the industrial camera arranged on one side, and obtain the compression rate of the yarn, realizing the detection of the softness of the yarn. Through the rotation of the fixed bin, continuous compression detection can be realized during the yarn introduction. At the same time, the air pump inside the fixed bin can input gas into the fixed sleeve and the connecting rod, thereby realizing the pressure adjustment of the pressing plate, and thus facilitating the detection of the compression amount of the yarn under different pressures, which is beneficial to completing the comprehensive detection work of the yarn.

[0021] 2. During detection, the operation of the electric push rod can drive the first carriage to move, and the first carriage can drive the moving wheels to move synchronously, thereby realizing the adjustment of the ratio between the supported length and the sagging length of the yarn, which is beneficial to obtaining the bending amplitude range and average value of the yarn under different supported lengths and sagging lengths, so as to obtain the softness data of this type of yarn and realize the rapid and accurate detection of the softness of the yarn. When the sagging yarn is detected by the optical camera, the operation of the threaded rod can drive the optical camera to move up and down, so that when the sagging length of the yarn changes, the optical camera can move along with the yarn, realizing the follow-up detection of the softness of this section of the yarn. At the same time, the cylinder at the end of the first fixed frame can expand and contract accordingly, driving the second limiting frame and the optical camera to shift as a whole, so that the sagging part of the yarn can still be detected by overall shooting after the sagging length of the yarn changes, which is beneficial to practical use.

[0022] 3. In the process of testing the softness of the yarn, people can start the air pump inside the pump bin. Through the operation of the air pump, the surrounding gas can be extracted through the air suction port, so that the yarn on the guide belt can be cleaned through the through port, thereby avoiding the dust on the yarn and causing errors in the subsequent drooping bending detection process. The gas discharged by the air pump can drive the impeller to rotate, and the impeller can drive the cleaning roller to rotate synchronously. The cleaning roller can clean the guide belt inside the guide belt to avoid dust sticking to the yarn later. At the same time, the gas can be discharged from the transfer bin through the air outlet pipe, and the inside of the connecting cover can be impacted by the airflow, thereby further improving the cleaning effect of the guide belt, which is beneficial to the actual use of the yarn detector.

[0033] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and other obvious variations can be thought of by those skilled in the art.

[0034] As Figures 1-9A yarn softness detection device shown includes a yarn detector 1. The yarn detector 1 includes a housing 101. Inside the housing 101, multiple detection components are provided. Each detection component includes a guiding belt 140. On both outer sides of the guiding belt 140, meshing teeth 133 are provided. In the middle of the guiding belt 140, uniformly distributed through holes 146 are formed. On the inner side of the guiding belt 140, a fixed wheel 127, a bottom wheel 149 and a moving wheel 115 are provided respectively. The bottom wheels 149 are all arranged below the fixed wheels 127. The moving wheels 115 are all arranged on one side of the fixed wheels 127. In the middle of the fixed wheels 127, mounting frames 129 are rotatably connected respectively. The mounting frames 129 are all fixedly connected inside the housing 101. In the middle of the bottom wheels 149, sliding frames two 113 are rotatably connected respectively. In the middle of the moving wheels 115, sliding frames one 134 are rotatably connected respectively. The sliding frames one 134 are all slidably connected inside the housing 101. On one side of the mounting frames 129, fixing frames two 130 are fixedly connected respectively. The fixing frames two 130 are all arranged on the side of the fixed wheels 127 close to the moving wheels 115. In the middle of the side of the fixing frames two 130 close to the moving wheels 115, electric push rods 128 are installed respectively. At the end of the electric push rods 128 away from the fixing frames two 130, fixing frames one 137 are installed respectively. The fixing frames one 137 are all installed at the ends of the sliding frames one 134. At the end of the fixing frames one 137 away from the electric push rods 128, side frames 138 are installed through cylinders. At the end of the side frames 138 away from the fixing frames one 137, limiting frames two 117 are fixedly connected respectively. Inside the limiting frames two 117, an optical camera 135 is slidably connected to a part close to the guiding belt 140. In the middle of the limiting frames two 117, threaded rods 116 are installed respectively. In the middle of the threaded rods 116, the optical cameras 135 are installed respectively;

[0035] Further, in specific implementation, during the rotation of the fixed shaft 122, the driven gear 121 on the outer periphery of the fixed shaft 122 can drive the meshing active gear 123 on one side for synchronous detection. Through the active gear 123, the meshing teeth 133 meshing with it can drive the guide belt 140 to rotate integrally. Through the guide belt 140, further guiding of the yarn can be achieved. The end of the yarn will droop naturally after passing through the moving wheel 115. At this time, the optical camera 135 can take pictures and measure the yarn to detect the bending degree of the yarn when it droops naturally. During the detection, the operation of the electric push rod 128 can drive the carriage one 134 to move. Through the carriage one 134, the moving wheel 115 can be driven to move synchronously, so as to adjust the ratio between the support length and the drooping length of the yarn, which is beneficial to obtaining the bending amplitude range and average value of the yarn under different support lengths and drooping lengths, and thus the softness data of this type of yarn can be obtained, realizing the rapid and accurate detection of the yarn softness. When the optical camera 135 takes pictures and detects the drooping yarn, the operation of the threaded rod 116 can drive the optical camera 135 to move up and down, so that when the drooping length of the yarn changes, the optical camera 135 can follow the yarn to move, realizing the follow-up detection of the softness of this section of the yarn. At the same time, the cylinder at the end of the fixing frame one 137 can extend and retract accordingly, driving the overall offset of the limiting frame two 117 and the optical camera 135, so that the drooping part of the yarn can still be photographed and detected as a whole after the drooping length of the yarn changes, which is beneficial to actual use. At the same time, the end of the drooping yarn can be led out of the housing 101 through the yarn outlet 105, so as to realize the all-round detection of the yarn sample, avoiding the situation that only the end of the sample is detected and the result is biased, and greatly improving the accuracy of the detection result.

[0036] Among them, an operation panel 102 is installed at the front of the housing 101. A protective cover 103 is slidably connected to the upper part of one side of the housing 101. A plurality of yarn outlets 105 are arranged on the other side of the housing 101. The bottom of the mounting frame 129 is fixedly connected with a limiting frame one 114. The limiting frame one 114 is fixedly connected to the lower part of one side inside the housing 101. The lower parts of the limiting frame one 114 penetrate through both ends of the carriage two 113, and the limiting frame one 114 is slidably connected with the carriage two 113. The upper parts of the outer peripheries of the limiting frame one 114 are sleeved with top springs 112, and the top springs 112 are arranged between the mounting frame 129 and the carriage two 113. The middle part of one side of the through pipe 125 is fixedly connected with a connecting pipe 142. The end of the connecting pipe 142 far away from the through pipe 125 is fixedly connected with a hose 141. The end of the hose 141 far away from the connecting pipe 142 is fixedly connected with a nozzle 139. The top of the nozzle 139 is fixedly connected with a fixing rod 136, and the fixing rod 136 is fixedly connected to the bottom of one side of the fixing frame one 137. A wind shield is installed between the pump chamber 106 and the connecting cover 109 and the yarn drooping and bending degree detection area;

[0037] Furthermore, during specific implementation, when part of the air flow passes through the through pipe 125, it will be led out through the connecting pipe 142. Then, under the action of the flexible pipe 141 and the side frame 138, the air flow can be further led out. The discharged air flow exists below the moving wheel 115, so that it can pass through the through port 146, pass through the guiding belt 140, and blow on the yarn, enabling the yarn to swing. The swinging yarn can be photographed and detected by the optical camera 135. By detecting the swinging amplitude of the yarn at different sagging lengths, the softness of the yarn can be further detected. The air blowing detection is carried out sequentially after the normal sagging curvature detection.

[0038] Among them, guide frames 118 are arranged on one side of the upper part of the fixed wheels 127. One end of each guide frame 118 is fixedly connected to a yarn feeding table 104. One side of the top of each yarn feeding table 104 is fixedly connected to a clamping post 110. Guide yarn rollers 111 are installed in the middle of each yarn feeding table 104. Fixed bins 108 are arranged on the upper part of each guide frame 118. Fixed shafts 122 penetrate through the middle of each fixed bin 108. The fixed shafts 122 are all installed on one side of the upper part inside the housing 101. Air pumps are arranged inside each fixed bin 108. Uniformly distributed fixed sleeves 107 are fixedly connected to the outer periphery of each fixed bin 108. Connecting rods 148 are slidably connected inside each fixed sleeve 107. One end of each connecting rod 148 away from the fixed sleeve 107 is fixedly connected to a pressing plate 119. Guide wheels 120 are fixedly connected to the outer periphery of each fixed bin 108. Driven gears 121 are installed on the front and rear sides of each fixed bin 108. One side of each driven gear 121 is meshed with a driving gear 123. The driving gears 123 are all fixedly connected to the upper part of the top frame 124. The top frames 124 are all installed on the upper part of the mounting frame 129. The bottoms of the driving gears 123 are meshed with meshing teeth 133;

[0039] Furthermore, during specific implementation, people can put the small sample of the yarn to be detected on the clamping post 110, then lead out one end of the yarn and pass it through the guide yarn roller 111. The guide yarn roller 111 can further guide the yarn into the yarn detector 1. Then, the motor can drive the fixed bin 108 to rotate by using the fixed shaft 122. When the fixed bin 108 rotates, the pressing plate 119 can press down the yarn passing below. The industrial camera arranged on one side can photograph the compressed state of the yarn and obtain the compression rate of the yarn, realizing the detection of the softness of the yarn. The rotation of the fixed bin 108 can realize continuous compression detection during the yarn introduction. At the same time, the air pump inside the fixed bin 108 can input gas into the fixed sleeve 107 and the connecting rod 148, so as to realize the pressure adjustment of the pressing plate 119, facilitating the detection of the compression amount of the yarn under different pressures and being conducive to completing the comprehensive detection work of the yarn.

[0040] Among them, pump chambers 106 are installed on one side of the outer periphery of the electric push rod 128. Air extraction ports 147 are evenly distributed and opened at the tops of the pump chambers 106. The pump chambers 106 are all arranged at the upper inner part of the guiding belt 140. Air pumps are installed inside the pump chambers 106. The input ends of the air pumps are all communicated with the air extraction ports 147. The output ends of the air pumps are all communicated with connecting pipes 125. The connecting pipes 125 are all fixedly connected to one side of the bottom of the pump chambers 106. The bottoms of the pump chambers 106 are fixedly connected with connecting frames 126. The bottoms of the connecting frames 126 are all fixedly connected with communicating covers 109. The communicating covers 109 are sleeved on the outer periphery of the lower part of the guiding belt 140. The bottoms of the connecting pipes 125 are communicated with the inside of the communicating covers 109. One side of the bottom of each communicating cover 109 is fixedly connected with a bottom pipe 131. One end of the bottom pipe 131 away from the communicating cover 109 is fixedly connected with a transfer chamber 132. Impellers 145 are arranged inside the transfer chambers 132. One end of each impeller 145 is fixedly connected with a cleaning roller 144. The cleaning rollers 144 are all rotatably connected to the lower inner part of the communicating cover 109. The cleaning rollers 144 are all arranged at the lower part of the guiding belt 140. Air outlet pipes 143 are fixedly connected to the front and rear parts of the outer periphery of the transfer chamber 132. One end of each air outlet pipe 143 away from the transfer chamber 132 faces the cleaning roller 144;

[0041] Further, in specific implementation, during the process of detecting the softness of the yarn, people can start the air pump inside the pump chamber 106. Through the operation of the air pump, the surrounding gas can be extracted by the air extraction port 147, so that the yarn on the guiding belt 140 can be cleaned through the through port 146, thereby avoiding errors in the subsequent sagging and bending detection process due to dust on the yarn. At the same time, after being filtered by the filter screen at the outlet end, the gas discharged by the air pump will enter the inside of the communicating cover 109 under the action of the connecting pipe 125. Through the bottom pipe 131 at the bottom of the communicating cover 109, the gas can be introduced into the transfer chamber 132, which will impact the impeller 145 inside the transfer chamber 132, thereby driving the impeller 145 to rotate. Through the impeller 145, the cleaning roller 144 can be driven to rotate synchronously. Through the cleaning roller 144, the guiding belt 140 can be cleaned inside the guiding belt 140 to prevent dust from sticking to the yarn subsequently. At the same time, the gas can be discharged from the transfer chamber 132 through the air outlet pipe 143, and the inside of the communicating cover 109 can be impacted by the air flow, thereby further improving the cleaning effect on the guiding belt 140, which is beneficial to the actual use of the yarn detector 1.

[0042] Among them, a method for detecting the softness of yarn includes the following detection steps:

[0043] S1. Put the small sample of the yarn to be detected on the clamping post 110. Then, lead one end of the yarn out and pass it through the yarn guiding roller 111. Further guide the yarn into the yarn detector 1 through the yarn guiding roller 111. Then, drive the fixed bin 108 to rotate by the motor using the fixed shaft 122. When the fixed bin 108 rotates, press down the yarn passing below through the pressing plate 119. Take a picture of the compressed state of the yarn by the industrial camera set on one side, and obtain the compression rate of the yarn to realize the detection of the softness of the yarn. Realize continuous compression detection during the yarn introduction by the rotation of the fixed bin 108;

[0044] S2. Through the pressure adjustment of the pressing plate 119, realize the detection of the compression amount of the yarn under different pressures. During the rotation of the fixed shaft 122, drive the meshing driving gear 123 on one side to perform synchronous detection through the driven gear 121 on the outer periphery of the fixed shaft 122. Drive the guiding belt 140 to rotate integrally through the meshing teeth 133 meshing with the driving gear 123. Further guide the yarn through the guiding belt 140. The end of the yarn will droop naturally after passing through the moving wheel 115. At this time, take a picture and measure the yarn by the optical camera 135;

[0045] S3. During the detection, drive the carriage one 134 to move through the work of the electric push rod 128, and drive the moving wheel 115 to move synchronously through the carriage one 134, so as to realize the adjustment of the ratio between the supporting length and the drooping length of the yarn, and obtain the bending amplitude range and average value of the yarn under different supporting lengths and drooping lengths;

[0046] S4. When taking pictures and detecting the drooping yarn by the optical camera 135, drive the optical camera 135 to move up and down through the work of the threaded rod 116, so that when the optical camera 135 changes the drooping length of the yarn, the optical camera 135 follows the yarn to move, realizing the follow-up detection of the softness of this section of the yarn;

[0047] S5. During the process of detecting the softness of the yarn, extract the surrounding gas through the air pump using the air extraction port 147, so as to clean the yarn on the guiding belt 140 through the through port 146. At the same time, clean the guiding belt 140 inside the guiding belt 140 through the cleaning roller 144 to avoid subsequent adhesion of dust to the yarn. At the same time, export the gas from the inside of the transfer bin 132 through the air outlet pipe 143, and impact the inside of the connecting cover 109 through the air flow to clean the guiding belt 140.

[0048] Working principle:

[0049] In actual use, people can put the small sample of the yarn to be detected on the clamping post 110, and then lead out one end of the yarn and pass it through the yarn guide roller 111. Through the yarn guide roller 111, the yarn can be further guided into the yarn detector 1. Then, through the motor, the fixed bin 108 can be driven to rotate by the fixed shaft 122. When the fixed bin 108 rotates, the pressing plate 119 can press down the yarn passing below. Through the industrial camera set on one side, the compression state of the yarn can be photographed, and the compression rate of the yarn can be obtained, so as to realize the detection of the softness of the yarn. Through the rotation of the fixed bin 108, continuous compression detection can be realized during the yarn introduction. At the same time, the air pump inside the fixed bin 108 can input gas into the fixed sleeve 107 and the connecting rod 148, so as to realize the pressure adjustment of the pressing plate 119, and thus facilitate the detection of the compression amount of the yarn under different pressures, which is beneficial to complete the comprehensive detection work of the yarn. During the rotation of the fixed shaft 122, the driven gear 121 on the outer periphery of the fixed shaft 122 can drive the meshing active gear 123 on one side for synchronous detection. Through the active gear 123, the guiding belt 140 can be driven to rotate integrally by the meshing teeth 133 engaged with it. Through the guiding belt 140, the yarn can be further guided. The end of the yarn will naturally droop after passing through the moving wheel 115. At this time, the optical camera 135 can photograph and measure the yarn to realize the detection of the bending degree of the yarn when it naturally droops. During the detection, through the work of the electric push rod 128, the sliding frame one 134 can be driven to move. Through the sliding frame one 134, the moving wheel 115 can be driven to move synchronously, so as to realize the adjustment of the ratio between the support length and the drooping length of the yarn, which is beneficial to obtain the bending amplitude range and average value of the yarn under different support lengths and drooping lengths, so as to obtain the data of the softness of this type of yarn and realize the rapid and accurate detection of the softness of the yarn. When the optical camera 135 photographs and detects the drooping yarn, through the work of the threaded rod 116, the optical camera 135 can be driven to move up and down, so that the optical camera 135 can follow the yarn to move when the drooping length of the yarn changes, realizing the follow-up detection of the softness of this section of the yarn. At the same time, the cylinder at the end of the fixed frame one 137 can expand and contract accordingly, driving the limit frame two 117 and the optical camera 135 to shift as a whole, so that the drooping part of the yarn can still be photographed and detected as a whole after the drooping length of the yarn changes, which is beneficial to actual use. At the same time, the end of the drooping yarn can be led out of the housing 101 through the yarn outlet 105, so as to realize the all-round detection of the yarn sample and avoid the situation that the result is deviated due to only detecting the end of the sample, greatly improving the accuracy of the detection result. At the same time, during the detection of the softness of the yarn, people can start the air pump inside the pump bin 106. Through the work of the air pump, the surrounding gas can be extracted through the air extraction port 147.Thus, it is possible to clean the yarn on the guiding belt 140 through the through-port 146, thereby avoiding errors in the subsequent sagging and bending detection process caused by dust on the yarn. At the same time, after being filtered by the outlet-end filter screen, the gas discharged by the air pump will enter the inside of the connecting cover 109 under the action of the connecting pipe 125. The gas can be introduced into the transfer bin 132 through the bottom pipe 131 at the bottom of the connecting cover 109, thereby impacting the impeller 145 inside the transfer bin 132, and thus driving the impeller 145 to rotate. The cleaning roller 144 can be driven to rotate synchronously by the impeller 145. The cleaning roller 144 can clean the guiding belt 140 inside the guiding belt 140 to prevent dust from sticking to the yarn subsequently. At the same time, the gas can be led out of the transfer bin 132 through the air outlet pipe 143, and the inside of the connecting cover 109 can be impacted by the air flow, thereby further improving the cleaning effect on the guiding belt 140, which is beneficial to the actual use of the yarn detector 1. At the same time, when part of the air flow passes through the connecting pipe 125, it will be led out through the connecting pipe 142, and then the air flow can be further led out under the action of the flexible pipe 141 and the side frame 138. The discharged air flow exists below the moving wheel 115, so that it can pass through the guiding belt 140 through the through-port 146 and blow the yarn, thereby making the yarn swing. The swinging yarn can be photographed and detected by the optical camera 135. By detecting the swing amplitude of the yarn at different sagging lengths, the softness of the yarn can be further detected.
