Description

Technical Field

[0001] This invention relates to the field of testing device technology, specifically to a new material production blended yarn testing device. Background Technology

[0002] Blended yarn is a yarn made by mixing two or more different fibers in a certain proportion. It combines the characteristics of different fibers and has some of the advantages of chemical fibers.

[0003] Patent CN214096944U discloses a blended yarn testing device, including a housing. A first motor is fixedly installed on the left side of the inner wall of the housing. A threaded column is fixedly connected to the output end of the first motor, and the right end of the threaded column is rotatably connected to the inner wall of the housing via a bearing. A threaded sleeve is threadedly connected to the surface of the threaded column, and the surface of the threaded sleeve is slidably connected to the inner wall of the housing. A first connecting rod is fixedly connected to the top surface of the threaded sleeve. A sliding groove is formed on the top surface of the housing, and the surface of the first connecting rod is slidably connected to the inner wall of the sliding groove. A first sliding sleeve is fixedly connected to the top surface of the first connecting rod, and a sliding rod is slidably connected to the inner wall of the first sliding sleeve. A first support rod is fixedly connected to the left side of the bottom surface of the sliding rod. This device achieves the effect of convenient and rapid testing of the tensile strength of blended yarns. The overall structure of the device is relatively simple, the maintenance cost is low, the operation steps are few, and it is more convenient to use and has good practicality. However, when fixing the yarn, the operator needs to manually tie the yarn into knots, which is very complicated and inconvenient. Therefore, a new material production blended yarn testing device is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a new material production blended yarn testing device to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a new material production blended yarn testing device, including a base, a guide platform fixedly connected to the top of the base, an observation shell fixedly connected to the top of the base, a motor fixedly connected to the inner wall of the guide platform, a rotating shaft fixedly connected to the output end of the motor, an L-shaped rod fixedly connected to the circumferential surface of the rotating shaft, a block fixedly connected to the inner wall of the L-shaped rod, a U-shaped pressure plate slidably connected to the inner wall of the block, a moving rod slidably connected to the inner wall of the block via a spring, a sliding rod slidably connected to the inner wall of the L-shaped rod, a support plate fixedly connected to the circumferential surface of the L-shaped rod, a telescopic plate rotatably connected to the inner wall of the support plate, a multi-functional detection yarn-pulling mechanism provided on the top of the base, a cleaning mechanism for cleaning damaged yarns provided on the top of the base, a connecting block fixedly connected to the circumferential surface of the sliding rod, a winding platform fixedly connected to the top of the base, and the inner wall of the guide platform rotatably connected to the circumferential surface of the rotating shaft. The measuring shell serves to observe during testing and protect the testing personnel. The inner wall of the U-shaped pressure plate is fixedly connected to the circumferential surface of the moving rod, and the U-shaped pressure plate is used to limit the yarn and prevent it from deviating. The front part of the U-shaped pressure plate is rotatably connected to the inner wall of the telescopic plate, and the side of the telescopic plate away from the U-shaped pressure plate is rotatably connected to the rear part of the connecting block. The sliding rod acts as an on / off switch during yarn testing. The winding table is used to fix the yarn. During yarn testing, the yarn can be stretched by rotating the shaft. When the L-shaped rod rotates, it will compress the yarn, thereby increasing the tensile strength of the yarn and shortening the testing time. By setting multiple L-shaped rods, yarn can be tested in batches, improving the yarn testing efficiency. At the same time, the yarn can be pressed at the bottom of the U-shaped pressure plate to prevent the yarn from deviating during testing, which would cause uneven force on the yarn and affect the testing effect. It can also quickly fix the yarn, improving the yarn testing efficiency.

[0006] Preferably, the wire-picking mechanism includes a V-shaped frame, which is fixedly connected to the top of the base. A reciprocating lead screw is rotatably connected to the inner wall of the V-shaped frame. A pulley assembly is fixedly connected to the circumferential surface of the rotating shaft. A movable plate is movably connected to the circumferential surface of the reciprocating lead screw. A straight plate is fixedly connected to the left side of the V-shaped frame. A fixed rod is fixedly connected to the inner wall of the straight plate. An elastic plate is fixedly connected to the top of the movable plate. A fixed plate is fixedly connected to the bottom of the movable plate. A push plate is fixedly connected to the inner wall of the fixed plate. The axis of the left pulley of the pulley assembly is fixedly connected to the circumferential surface of the reciprocating lead screw. The inner wall of the movable plate slides against the circumferential surface of the fixed rod. The connection is such that the fixed rod limits the movement of the movable plate to prevent it from rotating when it slides. The top of the base is in contact with the bottom of the push plate, and the push plate cleans up any broken threads. During the testing process, the movable plate moves, causing the elastic sheet to move, thus enabling diverse yarn testing. By applying different forces, the testing effect of the yarn in different environments can be tested. At the same time, during testing, the fixed plate moves, causing the push plate to move, thereby pushing out any broken yarns during the testing process into the testing area, preventing the yarns from getting tangled on the components of the testing equipment, affecting the normal operation of the equipment, and causing inaccurate test data or equipment malfunction.

[0007] Preferably, the cleaning mechanism includes a fixed column, which is fixedly connected to the top of the base. A ramp is slidably connected to the circumferential surface of the fixed column via a spring. A U-shaped frame is fixedly connected to the left side of the ramp. A protrusion is fixedly connected to the bottom of the U-shaped frame. An L-shaped plate is fixedly connected to the front of the push plate. A twisted wire roller is rotatably connected to the inner wall of the L-shaped plate. A transmission wheel is fixedly connected to the circumferential surface of the twisted wire roller. The top of the push plate contacts the bottom of the U-shaped frame, and the movement trajectory of the push plate contacts the protrusion. The top of the base contacts the circumferential surface of the transmission wheel, and the transmission wheel communicates with the top of the base. The yarn roller, which comes into contact with and rotates, is used to collect yarn during operation. During the yarn cleaning process, multiple protrusions allow the inclined plate to move up and down repeatedly, thereby gathering the yarn scattered on the inner edge of the device towards the center. This makes it easier to collect and clean the yarn, further improving the yarn cleaning effect and reducing the impact of the yarn on the device. At the same time, during yarn cleaning, the drive wheel rotates, driving the yarn roller to rotate. This allows any small amount of yarn that was missed during cleaning to be agitated and wrapped around the surface of the yarn roller, reducing the impact of the yarn on the detection.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This new material produces a blended yarn testing device. Through the coordinated operation of the base, guide platform, observation shell, motor, rotating shaft, L-shaped rod, square block, U-shaped pressure plate, moving rod, sliding rod, support plate, telescopic plate, connecting block, and winding table, the device performs yarn testing. During yarn testing, the rotating shaft performs tensile testing on the yarn, and the rotating L-shaped rod compresses the yarn, increasing its tensile strength and shortening the testing time. By setting multiple L-shaped rods, yarns can be tested in batches, improving testing efficiency. The device also presses the yarn against the bottom of the U-shaped pressure plate, preventing yarn deviation during testing and ensuring even force distribution, thus improving testing results. Furthermore, it quickly fixes the yarn, further enhancing testing efficiency.

[0010] 2. The new material production blended yarn testing device, through the coordinated operation of V-shaped frame, reciprocating screw, pulley group, moving plate, straight plate, fixed rod, and elastic plate, allows for diverse yarn testing during the testing process. By applying different forces, the testing effect of the yarn under different environments can be tested.

[0011] 3. The new material production blended yarn testing device, through the coordinated operation between the fixed plate and the push plate, during the testing process, the fixed plate moves and drives the push plate to move, thereby pushing out the yarn that breaks during the testing process into the testing area, avoiding the yarn from getting tangled on the parts of the testing equipment, affecting the normal operation of the equipment, and causing inaccurate test data or equipment failure.

[0012] 4. The new material produces a blended yarn detection device. Through the coordinated operation of the fixed column, inclined plate, U-shaped frame, and protrusions, the inclined plate can move up and down during the yarn cleaning process. This allows the yarn scattered on the inner edge of the device to be gathered in the middle, making it easier to collect and clean the yarn. This further improves the yarn cleaning effect and reduces the impact of the yarn on the device.

[0013] 5. The new material produces a blended yarn detection device. Through the coordinated operation of the L-shaped plate, the stranding roller, and the drive wheel, the drive wheel rotates during yarn cleaning, which drives the stranding roller to rotate. This allows any small amount of yarn that was missed during cleaning to be agitated and wrapped around the surface of the stranding roller, reducing the impact of the yarn on the detection.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-7One embodiment of the present invention is as follows: a new material production blended yarn testing device, comprising a base 1, a guide platform 2 fixedly connected to the top of the base 1, an observation shell 3 fixedly connected to the top of the base 1, a motor 4 fixedly connected to the inner wall of the guide platform 2, a rotating shaft 5 fixedly connected to the output end of the motor 4, an L-shaped rod 6 fixedly connected to the circumferential surface of the rotating shaft 5, a block 7 fixedly connected to the inner wall of the L-shaped rod 6, a U-shaped pressure plate 8 slidably connected to the inner wall of the block 7, a moving rod 9 slidably connected to the inner wall of the block 7 via a spring, a sliding rod 10 slidably connected to the inner wall of the L-shaped rod 6, a support plate 11 fixedly connected to the circumferential surface of the L-shaped rod 6, a telescopic plate 12 rotatably connected to the inner wall of the support plate 11, and a multi-functional detection yarn-pulling mechanism provided on the top of the base 1. 15. A cleaning mechanism 16 for cleaning damaged yarn is provided on the top of the base 1. A connecting block 13 is fixedly connected to the circumferential surface of the sliding rod 10. A winding table 14 is fixedly connected to the top of the base 1. The inner wall of the guide table 2 is rotatably connected to the circumferential surface of the rotating shaft 5. The observation shell 3 is used for observation during testing and to protect the testing personnel. The inner wall of the U-shaped pressure plate 8 is fixedly connected to the circumferential surface of the moving rod 9. The U-shaped pressure plate 8 is used to limit the yarn and prevent the yarn from running off-center. The front part of the U-shaped pressure plate 8 is rotatably connected to the inner wall of the telescopic plate 12. The side of the telescopic plate 12 away from the U-shaped pressure plate 8 is rotatably connected to the rear part of the connecting block 13. The sliding rod 10 is used as a switch when testing yarn. The winding table 14 is used to fix the yarn.

[0024] When performing yarn testing, the protective door on the top of the observation shell 3 is opened, and the yarn roll is fixed on the winding table 14. After the yarn is fixed, the motor 4 is started to drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the L-shaped rod 6 to rotate, so that the yarn can be tensile tested by the rotation of the rotating shaft 5. When the L-shaped rod 6 rotates, it will squeeze the yarn to increase the tensile strength of the yarn, thereby shortening the testing time. By setting multiple L-shaped rods 6, the yarn can be tested in batches, improving the yarn testing efficiency.

[0025] When fixing the yarn, press down on the sliding rod 10. The sliding rod 10 moves downward, causing the connecting block 13 to move downward. The downward movement of the connecting block 13 causes the telescopic plate 12 to rotate and compress. The rotation of the telescopic plate 12 causes the U-shaped pressure plate 8 to move upward, thereby pressing the yarn at the bottom of the U-shaped pressure plate 8. This prevents the yarn from running off-center during testing, which would cause uneven force on the yarn and affect the testing effect. It can also quickly fix the yarn and improve the yarn testing efficiency.

[0026] Overall working principle: When performing yarn testing, the protective door on the top of the observation shell 3 is opened, and the yarn roll is fixed on the winding table 14. After the yarn is fixed, the motor 4 is started to drive the rotating shaft 5 to rotate. The rotating shaft 5 drives the L-shaped rod 6 to rotate, and then the L-shaped rod 6 stretches the yarn to perform strength testing. At the same time, after the yarn is fixed, the sliding rod 10 is pressed so that the U-shaped pressure plate 8 can fix the yarn and prevent it from deviating.

[0027] The wire-picking mechanism 15 includes a V-shaped frame 151, which is fixedly connected to the top of the base 1. A reciprocating lead screw 152 is rotatably connected to the inner wall of the V-shaped frame 151. A pulley assembly 153 is fixedly connected to the circumferential surface of the rotating shaft 5. A movable plate 154 is movably connected to the circumferential surface of the reciprocating lead screw 152. A straight plate 155 is fixedly connected to the left side of the V-shaped frame 151. A fixed rod 156 is fixedly connected to the inner wall of the straight plate 155. An elastic plate 157 is fixedly connected to the top of the movable plate 154. A fixed plate 158 is fixedly connected to the bottom of 4. A push plate 159 is fixedly connected to the inner wall of the fixed plate 158. The left pulley shaft of the pulley assembly 153 is fixedly connected to the circumferential surface of the reciprocating screw 152. The inner wall of the moving plate 154 is slidably connected to the circumferential surface of the fixed rod 156. When the moving plate 154 slides, the fixed rod 156 will limit it to prevent the moving plate 154 from rotating. The top of the base 1 is in contact with the bottom of the push plate 159, and the push plate 159 cleans up the broken lines.

[0028] During the testing process, the rotating shaft 5 rotates, driving the pulley assembly 153 to rotate. The pulley assembly 153 drives the reciprocating screw 152 to rotate via a belt. The rotation of the reciprocating screw 152 causes the slider on the inner wall of the moving plate 154 to contact the thread on the surface of the reciprocating screw 152, thereby causing the moving plate 154 to move. The moving plate 154 will contact the fixed rod 156 during its movement, and the fixed rod 156 will limit the movement of the moving plate 154 to prevent it from rotating during the movement, which would affect the normal movement of the moving plate 154. The movement of the moving plate 154 drives the elastic sheet 157 to move, thus enabling diverse testing of the yarn. By applying different forces, the testing effect of the yarn in different environments can be tested.

[0029] During testing, the moving plate 154 moves, causing the fixed plate 158 to move, and the fixed plate 158 moves, causing the push plate 159 to move. This allows the yarn that breaks during the testing process to be pushed out of the testing area, preventing the yarn from getting tangled on the components of the testing equipment, affecting the normal operation of the equipment, and causing inaccurate test data or equipment malfunction.

[0030] Overall working principle: During the testing process, the rotating shaft 5 rotates, driving the pulley assembly 153 to rotate. The pulley assembly 153 drives the reciprocating screw 152 to rotate via the belt. The movement of the reciprocating screw 152 drives the moving plate 154 to move. The moving plate 154 drives the elastic plate 157 to move, which can cause the yarn to deform under a certain external force. Then, its ability to return to its original shape is observed to evaluate the elastic performance of the yarn. At the same time, the movement of the fixed plate 158 drives the push plate 159 to move, which can clean the yarn and prevent the yarn from getting tangled on the reciprocating screw 152.

[0031] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the cleaning mechanism 16 includes a fixed column 161, which is fixedly connected to the top of the base 1. The circumferential surface of the fixed column 161 is slidably connected to an inclined plate 162 via a spring. A U-shaped frame 163 is fixedly connected to the left side of the inclined plate 162. A protrusion 164 is fixedly connected to the bottom of the U-shaped frame 163. An L-shaped plate 165 is fixedly connected to the front of the push plate 159. A stranded roller 166 is rotatably connected to the inner wall of the L-shaped plate 165. A transmission wheel 167 is fixedly connected to the circumferential surface of the stranded roller 166. The top of the push plate 159 is in contact with the bottom of the U-shaped frame 163, and the movement trajectory of the push plate 159 is in contact with the protrusion 164. The top of the base 1 is in contact with the circumferential surface of the transmission wheel 167, and the transmission wheel 167 rotates by contacting the top of the base 1. The stranded roller 166 is used to collect yarn during operation.

[0032] During the yarn cleaning process, the push plate 159 moves and comes into contact with the protrusion 164, exerting a squeezing force on the protrusion 164, forcing the protrusion 164 to move upward. The upward movement of the protrusion 164 drives the U-shaped frame 163 to move upward, which in turn drives the inclined plate 162 to move upward. The upward movement of the inclined plate 162 stretches the spring on the surface of the fixed column 161. After the push plate 159 passes the U-shaped frame 163, the protrusion 164 is no longer subjected to the squeezing force from the push plate 159, which causes the U-shaped frame 163 to move downward. Through the multiple protrusions 164, the inclined plate 162 can move up and down repeatedly, thereby gathering the yarn scattered on the inner edge of the device towards the center, making it easier to collect and clean the yarn, further improving the yarn cleaning effect and reducing the impact of the yarn on the device.

[0033] During yarn cleaning, the push plate 159 moves, causing the L-shaped plate 165 to move. The L-shaped plate 165 moves, causing the stranding roller 166 to move. The stranding roller 166 moves, causing the transmission wheel 167 to move. During the movement of the transmission wheel 167, it will contact the top of the base 1 and generate friction, so that the transmission wheel 167 can rotate through friction. The rotation of the transmission wheel 167 drives the stranding roller 166 to rotate, thereby agitating a small amount of yarn that was missed during cleaning and causing the yarn to wrap around the surface of the stranding roller 166, reducing the impact of the yarn on the detection.

[0034] Overall working principle: During the yarn cleaning process, the push plate 159 moves and contacts the protrusion 164, generating a squeezing force on the protrusion 164, forcing the protrusion 164 to move upward. The upward movement of the protrusion 164 drives the U-shaped frame 163 to move upward, thereby facilitating the collection and cleaning of the yarn, further improving the yarn cleaning effect and reducing the impact of the yarn on the device. At the same time, the transmission wheel 167 can rotate through friction, and the rotation of the transmission wheel 167 drives the twisting roller 166 to rotate, which can reduce the impact of the yarn on the device.

[0035] This invention provides a novel material blended yarn testing device. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
