Description

[0001] This application is a divisional application of the application with the application number 2024115574360, the application date of November 4, 2024, and the invention title of "An Elasticity Detection Device and Method for Non-woven Fabrics in Textile Production". Technical Field

[0002] The present invention relates to the technical field of elasticity detection, and specifically to an elasticity detection device for non-woven fabrics. Background Art

[0003] With the development of technology, the detection technology for textile products has gradually developed during the production process of textile products. In order to ensure the final finished product effect of textile products, it is necessary to sample products in each process section during the production process of textile products for performance testing, and non-woven fabrics are no exception. Among them, elasticity detection is an important link.

[0004] The patent with the patent announcement number CN218847818U discloses an elasticity detection device for non-woven fabrics in textile production, including a fabric elasticity detection base, a support arm, a fabric elasticity data control board, an electric sliding table, a fabric elasticity pulling seat, a fabric elasticity fixing seat, a fabric electric gripper, a protection mechanism, and a fabric waste dust collection mechanism; a support arm is fixedly installed at the top of the fabric elasticity detection base, and a fabric elasticity data control board is fixedly installed on the front side of the support arm. In this patent, the provided protection mechanism is used to protect the device components for detecting the elasticity of non-woven fabrics, and when the non-woven fabric is pulled and detected, it prevents the non-woven fabric from breaking and hurting people. In addition, the L-shaped cover of the protection mechanism can be disassembled and assembled by removing the screws, which is convenient for maintaining the internal components. The provided fabric waste dust collection mechanism is used to suck and collect the lint and fluff in the protective cover, which is convenient for cleaning the components of the detection device.

[0005] However, there are still deficiencies in the current device: while the device prevents the non-woven fabric from bursting and hurting people, it detects the elasticity of the non-woven fabric. However, during the clamping and stretching process of both ends of the non-woven fabric, wrinkles are likely to occur at the clamping ends of the non-woven fabric. When there are wrinkles at the clamping ends of the non-woven fabric, the clamping area is reduced, thereby reducing the clamping strength and increasing the risk of the clamping ends falling off. Moreover, when the wrinkled part is stretched, it is easy to cause certain wrinkles and twists in the overall detection part of the non-woven fabric, thus affecting the detection result. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides an elasticity detection device and method for non-woven fabrics in textile production, which solves the problems raised in the above background art.

[0007] To achieve the above object, the present invention is realized through the following technical solutions: A non-woven fabric elasticity detection device for textile production, including a base, a detection component is arranged on the top of the base. The inside of the detection component is hollow-designed. A display component is arranged above the front of the detection component. An L-shaped fixing component is arranged on the right side inside the detection component. A rotating component is arranged on the back of the inner wall of the L-shaped fixing component. A number of limiting holes are provided inside the rotating component. A socket rod is arranged at the center of the front of the rotating component. A pressing component is arranged on the right side inside the L-shaped fixing component. An electric slide rail is arranged on the back of the inner wall of the detection component. A transmission column is slidably installed inside the electric slide rail. A stretching component is fixedly installed on the outer wall of the transmission column. The stretching component is communicated with the display component through an intelligent module, and the bottom of the stretching component contacts the bottom of the inner wall of the detection component. A vertical plate is fixedly installed at the top edge of the stretching component. A pressing plate is slidably installed on the front of the vertical plate. Two rectangular grooves are provided inside the pressing plate. The two rectangular grooves are symmetrically distributed with the axis of the pressing plate as the center. A lead screw is rotatably installed on the left side inside the stretching component. A number of elastic pieces are fixedly installed at the top edge of the pressing plate. Elastic telescopic rods are fixedly installed on the concave surfaces of the tops of the inner walls of the elastic pieces. The bottom of the telescopic end of the elastic telescopic rod is fixedly installed with a positioning rubber plate. A round rod is fixedly installed on the inner wall of the rectangular groove of the pressing plate. An inclined push plate is penetrated and rotatably installed on the outer wall of the round rod. The non-woven fabric roller is sleeved on the outer wall of the socket rod. The staff pulls one end of the non-woven fabric and places it on the top plane of the stretching component. Rotate the lead screw. When the lead screw rotates, through the restriction of the spiral groove on its outer wall on the block inside the pressing plate, and the continuous contact of the block with the inner wall of the spiral groove of the lead screw, the pressing plate can slide downward along the outer wall of the lead screw. The back of the pressing plate is restricted by the vertical plate, so that the pressing plate can slide stably downward along the front of the vertical plate. After the pressing plate stably presses non-woven fabrics of different thicknesses, the staff inserts the round column into the limiting hole inside the rotating component to limit the rotating component. At the same time, the pressing component slides downward along the inner wall of the L-shaped fixing component to press the non-woven fabric roller to make it stationary;Meanwhile, when the pressing plate descends, the pressing plate drives the round rod and the inclined push plate to move synchronously. Since the inclined push plate is longer than the elastic telescopic rod and the positioning rubber plate, the inclined push plate is prompted to first contact the top of the non-woven fabric. The arc surface at the bottom of the inclined push plate and its own inclination angle enable the inclined push plate to push along the top of the non-woven fabric in a direction away from the center of the pressing plate. At this time, the inclined push plate starts to rotate along the outer wall of the round rod until the inclined push plate fits into the internal return groove of the pressing plate. Then, the bottom of the positioning rubber plate contacts and positions the four corners of the top of the non-woven fabric. As the pressing plate continues to descend, the resistance force causes the telescopic end of the elastic telescopic rod to contract upward. When the telescopic end of the elastic telescopic rod contracts to the bottom, the whole elastic telescopic rod slides upward and the contact elastic piece deforms. At this time, the positioning rubber plate fits into the internal round holes at the bottom of the pressing plate. The electric slide rail is started, and the electric slide rail drives the transmission column to slide leftward inside itself. The transmission column drives the stretching component to slide synchronously along the bottom of the inner wall of the detection component. The stretching component pulls the elastic detection part of the non-woven fabric to move and stretch synchronously. The stretching distance generated during the pulling process of the stretching component is converted into elastic detection data by the stretching component. Then, the detection signal source is transmitted to the display component through the intelligent module and displayed by the display component for the convenience of the staff to record.;

[0008] According to the above technical solution, a number of round holes are provided at the bottom of the pressing plate. The outer wall of the screw rod spiral groove contacts the inner wall of the pressing plate. The outer wall of the elastic telescopic rod movably penetrates the inside of the pressing plate. A torsion spring is provided between the inside of the round rod and the inclined push plate. A concave-convex prevention device for removing dirt or attachments on the inner side (i.e., the wound part) of the non-woven fabric is provided on the right side of the stretching component.

[0009] According to the above technical solution, the anti-convexity and concavity device includes two cross plates, a rotating wheel, a rotating rod, several U-shaped hollow frames, a top plate, a trapezoidal plate, a contact plate and a sliding rod. The left sides of the two cross plates are fixedly installed on the right side of the stretching component. The rotating wheel is rotatably installed on the inner wall of the cross plate on the side away from the center of the stretching component. The front and back ends of the rotating rod are fixedly installed at the center of the inner wall of the rotating wheel. A reciprocating spiral groove is formed at one end of the back surface of the rotating rod. Several U-shaped hollow frames are fixedly installed on the outer surface of the rotating rod. The front side of the top plate is vertically slidably installed on the front surface of the inner wall of the U-shaped hollow frame through a spring. The trapezoidal plate is penetrated and slidably installed inside the U-shaped hollow frame. The contact plate is penetrated and slidably installed on the outer wall of the reciprocating spiral groove of the rotating rod. The right end of the sliding rod is fixedly installed on the left side of the contact plate. When the stretching component moves to the left, it drives the cross plate to move synchronously. The cross plate drives the rotating wheel to move synchronously. The outer wall of the rotating wheel contacts the bottom of the inner wall of the detection component to generate frictional force. The rotating wheel starts to rotate due to the frictional force and drives the rotating rod to rotate. The rotating rod drives the U-shaped hollow frames to rotate. When the U-shaped hollow frames rotate, they scrape the bottom of the non-woven fabric. At the same time, the U-shaped hollow frames drive the top plate to move synchronously. When the rotating rod rotates, the restriction of the built-in block of the contact plate by the reciprocating spiral groove on its outer wall enables the contact plate to slide forward and reset along the outer wall of the reciprocating spiral groove of the rotating rod. The contact plate drives the sliding rod to slide along the right side of the stretching component. When the contact plate slides forward, it contacts the trapezoidal plate to move synchronously. And the trapezoidal plate will only be pushed and contacted by the contact plate when it rotates above the outer wall of the rotating rod. The trapezoidal plate slides synchronously along the inside of the U-shaped hollow frame through the contact force. At this time, the trapezoidal plate contacts the arc surface of the top plate to cause the top plate to generate an upward movement force. The top plate slides upward along the inner wall of the U-shaped hollow frame and contacts the non-woven fabric during stretching.

[0010] According to the above technical solution, the outer wall of the rotating wheel contacts the bottom of the inner wall of the detection component. Several U-shaped hollow frames are equidistantly distributed on the outer wall of the rotating rod. The bottom arc surface of the top plate is located on the movement track of the inclined surface of the trapezoidal plate. The front surface of the contact plate contacts the back surface of the trapezoidal plate. The left end of the sliding rod is slidably connected to the right side of the stretching component. A anti-fluctuation device for ensuring the constant temperature of the non-woven fabric itself during elastic stretching detection is provided on the left side of the U-shaped hollow frame.

[0011] According to the above technical solution, the anti-convexity and concavity device further includes several U-shaped plates and a receiving plate. The bottom of the inner walls of several U-shaped plates are fixedly installed on the bottom of the top plate. Several U-shaped plates are symmetrically distributed with the axis of the top plate as the center. The top of the receiving plate is hinged to the outer wall of the U-shaped hollow frame through a torsion spring. The inclined surface of the receiving plate contacts the top of the U-shaped plate. When the top plate moves upward, it drives the U-shaped plate to move synchronously. When the U-shaped plate moves upward, the top of the U-shaped plate contacts the inclined surface of the receiving plate to generate an upward contact force. At this time, the hinge shaft between the receiving plate and the U-shaped hollow frame starts to rotate, and the receiving plate moves upward in an arc trajectory parallel to the top plate.

[0012] According to the above technical scheme, the anti-fluctuation device includes two L-shaped plates, a circular plate and a hot air component. The left sides of the two L-shaped plates are slidably installed on the right side of the stretching component. The inside of the L-shaped plate passes through and is fixedly installed on the outer wall of the sliding rod. The front and back sides of the circular plate are fixedly installed between the outer walls of the two L-shaped plates. The back of the hot air component is fixedly installed on the front of the L-shaped plate. When the sliding rod slides forward and resets, it drives the L-shaped plate to slide synchronously along the right side of the stretching component. The two L-shaped plates slide synchronously through the circular plate, and the L-shaped plate drives the hot air component to move synchronously.

[0013] According to the above technical solution, the anti-wave device also includes a transmission rod and a plurality of fan plates, both ends of the front side of the transmission rod are penetrated and rotatably installed on the inner wall of the horizontal plate, a spiral groove is opened at one end of the back side of the transmission rod, and the spiral groove is located on the internal movement trajectory of the L-shaped plate, and a plurality of fan plates are equidistantly and fixedly installed on the outer wall of the transmission rod. When the L-shaped plate slides along the outer wall of the non-self-locking spiral groove of the transmission rod, the restriction of the inner wall of the spiral groove by the built-in block of the L-shaped plate causes the transmission rod to generate a rotational force and start to rotate, and the transmission rod drives the fan plate to rotate, and when the fan plate rotates, the airflow within the heating range of the bottom of the non-woven fabric is rotationally disturbed.

[0014] The cam is fixedly mounted on the front of the L-shaped plate, and the front end of the telescopic column is fixedly mounted on the back of the fixed ring. The back of the cam is rotatably mounted on the front of the outer wall of the L-shaped plate. The front of the cam is fixedly mounted on the back of the telescopic end of the telescopic column. The back of the L-shaped cover plate is vertically slidably mounted on the front of the L-shaped plate by a spring, and a round block is fixedly mounted on the top of the L-shaped cover plate, and the outer wall of the round block is in contact with the outer wall of the cam. At the same time, the fanning plate drives the fixed ring to rotate, the fixed ring drives the telescopic column to rotate, and the telescopic column drives the cam to rotate along the outer wall of the L-shaped plate. When the cam rotates, it contacts the round block on the top of the L-shaped cover plate, causing it to generate an upward force. The round block drives the L-shaped cover plate to move upward along the outer wall of the L-shaped plate. The elastic force of the spring limits the round block to always be close to the outer wall of the cam, so that the L-shaped cover plate can move back and forth up and down.

[0015] A method for using a non-woven fabric elasticity detection device for textile production comprises the following steps: S1: The non-woven fabric roller is sleeved on the outer wall of the sleeve rod. The staff pulls one end of the non-woven fabric and places it on the top plane of the stretching component. The screw is rotated. When the screw rotates, the spiral groove on its outer wall restricts the block inside the pressing plate. The block constantly contacts the inner wall of the spiral groove of the screw, so that the pressing plate can slide downward along the outer wall of the screw. The back of the pressing plate is restricted by the vertical plate, so that the pressing plate can slide downward stably along the front of the vertical plate. S2: After the pressing plate has stably pressed the non-woven fabrics of different thicknesses, the staff inserts the round column into the limiting hole of the rotating component to limit the rotating component. At the same time, the pressing component slides downward along the inner wall of the L-shaped fixed component to press the non-woven fabric roller to ensure that it is stationary; S3: At the same time, when the pressing plate descends, the pressing plate drives the round rod and the inclined push plate to move synchronously. Since the inclined push plate is longer than the elastic telescopic rod and the positioning rubber plate, the inclined push plate is first in contact with the top of the non-woven fabric, and the inclined push plate is pushed away from the center of the pressing plate along the top of the non-woven fabric through the arc surface at the bottom of the inclined push plate and its own inclination angle. At this time, the inclined push plate starts to rotate along the outer wall of the round rod until the inclined push plate fits into the inside of the circular groove of the pressing plate, and then the bottom of the positioning rubber plate contacts and positions the four corners of the top of the non-woven fabric. As the pressing plate continues to descend, the resistance force causes the telescopic end of the elastic telescopic rod to shrink upward. When the telescopic end of the elastic telescopic rod shrinks to the bottom, the elastic telescopic rod slides upward as a whole and the resistance spring is deformed. At this time, the positioning rubber plate fits into the inside of the circular hole at the bottom of the pressing plate; S4: Start the electric slide rail, which drives the transmission column to slide to the left inside itself. The transmission column drives the stretching component to slide synchronously along the bottom of the inner wall of the detection component. The stretching component pulls the elastic detection part of the non-woven fabric to stretch synchronously. The stretching distance generated by the stretching component during the pulling process is converted into elastic detection data by the stretching component. Then, the detection signal source is transmitted to the display component through the intelligent module, and displayed through the display component for the convenience of staff to record.

[0016] The present invention provides a non-woven fabric elasticity detection device and method for textile production, which has the following beneficial effects: (1) The present invention cooperates with an electric slide rail, a transmission column, a stretching assembly, a vertical plate, a pressure plate, a screw rod, a spring sheet, an elastic telescopic rod, a positioning rubber plate, a round rod and an inclined push plate, and relies on the flat pressing of a wide area at the bottom of the pressure plate to ensure stability during the stretching process. At the same time, the pressure plate achieves a good stable pressing effect for non-woven fabrics of different thicknesses through the screw rod, thereby improving the practicality of the detection component for elastic detection of different types of non-woven fabrics; and relies on the inclined push plate to smooth out the wrinkles at one end of the non-woven fabric clamping and stretching, and at the same time, the positioning rubber plate positions the four corners of the non-woven fabric after the wrinkles are smoothed, so as to prevent the non-woven fabric from sliding and deviating from the center part of the stretching assembly under external interference, and the positioning rubber plate and the inclined push plate can both fit inside the pressure plate to ensure that the bottom of the pressure plate contacts the non-woven fabric in a flat posture, effectively ensuring that the clamping area of the clamping end of the non-woven fabric will not be reduced, thereby preventing the stretching and falling phenomenon from occurring, and avoiding certain wrinkles and twists in the overall detection part of the non-woven fabric, thereby affecting the detection result.

[0017] (2) Through the arrangement of the anti-convexity and concavity device, the present invention realizes the rotary scraping of the bottom of the non-woven fabric, i.e., the side that is wound around the roller, through the cooperation of the stretching component, the cross plate, the rotating wheel, the rotating rod, the U-shaped hollow frame, the top plate, the trapezoidal plate, the abutting plate, the sliding rod, the U-shaped plate and the receiving plate. And the top plate indirectly pushes the non-woven fabric to cause it to bulge intermittently, so as to realize the uniform stretching of the non-woven fabric before static detection, ensure the tightness of stretching to avoid loosening and resulting in errors in the detection results, and at the same time ensure the cleanliness of the bottom of the non-woven fabric to avoid tight adhesion to each other when recycling and winding; and expand the receiving range of the receiving plate for dirt, and rely on the receiving plate to receive the solid particle dirt scraped off by the U-shaped hollow frame in real time, preventing the particulate matter from flying around and adhering to the rest of the area of the non-woven fabric when it falls due to the impact of rotating components such as the top plate.

[0018] (3) Through the arrangement of the anti-wave device, the present invention ensures the real-time blowing of hot air on the non-woven fabric through the cooperation of the sliding rod, the L-shaped plate, the U-shaped plate, the hot air component, the transmission rod, the fan plate, the fixed ring, the telescopic column, the cam and the L-shaped cover plate, and expands the activity range of the hot air component to avoid fixed-point blowing and promote uniform heating and stretching of the whole non-woven fabric, preventing the non-woven fabric from being eroded by moisture during the production process, resulting in an increase in fiber softness and a decrease in elastic value; and relying on the fan plate to quickly disturb and mix the heat flow and the moisture evaporated when the non-woven fabric is heated, ensuring a dry detection environment while ensuring uniform heating of the non-woven fabric and avoiding the occurrence of uniform high temperature phenomenon. At the same time, the L-shaped cover plate shields the top of the hot air component to prevent dirt from entering and guides the air flow deposited under the L-shaped plate, increasing the overall temperature of the internal space of the detection component and reducing the temperature difference.

Detailed implementation manners

[0021] 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 of the embodiments.

[0022] Please refer to Figures 1-9, an embodiment of the present invention is: a non-woven fabric elasticity detection device for textile production, including a base 1. A detection component 2 is arranged on the top of the base 1. The inside of the detection component 2 is hollow-designed. Above the front of the detection component 2, there is a display component 21. On the right side inside the detection component 2, there is an L-shaped fixing component 3. On the back of the inner wall of the L-shaped fixing component 3, there is a rotating component 31. Several limiting holes are opened inside the rotating component 31. At the center of the front of the rotating component 31, there is a socket rod 32. On the right side inside the L-shaped fixing component 3, there is a pressing component 33. On the back of the inner wall of the detection component 2, there is an electric slide rail 34. A transmission column 6 is slidably installed inside the electric slide rail 34. An extension component 7 is fixedly installed on the outer wall of the transmission column 6. The extension component 7 is communicated with the display component 21 through an intelligent module, and the bottom of the extension component 7 contacts the bottom of the inner wall of the detection component 2. At the edge of the top of the extension component 7, there is a vertical plate 8 fixedly installed. A pressing plate 9 is slidably installed on the front of the vertical plate 8. Two return-shaped grooves are opened inside the pressing plate 9, and the two return-shaped grooves are symmetrically distributed with the axis of the pressing plate 9 as the center. On the left side inside the extension component 7, there is a lead screw 10 rotatably installed. At the edge of the top of the pressing plate 9, there are several elastic pieces 11 fixedly installed. At the concave surface of the top of the inner wall of the several elastic pieces 11, there are elastic telescopic rods 12 fixedly installed. The bottom of the telescopic end of the elastic telescopic rod 12 is fixedly installed with a positioning rubber plate 13. A round rod 14 is fixedly installed on the inner wall of the return-shaped groove of the pressing plate 9. The outer wall of the round rod 14 penetrates through and rotatably installs an inclined push plate 15. Through the above cooperation, relying on the flat pressing of the wide area at the bottom of the pressing plate 9, the stability during the stretching process is ensured. At the same time, the pressing plate 9 realizes a good stable pressing effect for non-woven fabrics of different thicknesses through the lead screw 10, improving the practicability of the detection component 2 for the elasticity detection of different types of non-woven fabrics; through the above cooperation, relying on the inclined push plate 15 to smooth the wrinkles existing at the clamped and stretched end of the non-woven fabric, and at the same time, the positioning rubber plate 13 positions the four corners of the non-woven fabric after the wrinkles are smoothed, preventing the non-woven fabric from sliding and shifting under the interference of external forces and separating from the central part of the extension component 7. And both the positioning rubber plate 13 and the inclined push plate 15 can fit inside the pressing plate 9 to ensure that the bottom of the pressing plate 9 contacts the non-woven fabric in a flat state, effectively ensuring that the clamping area of the clamped end of the non-woven fabric will not shrink, thereby preventing the stretching and falling-off phenomenon from occurring, and avoiding certain wrinkles and twists in the overall detection part of the non-woven fabric, which may affect the detection result.

[0023] According to the above technical solution, several round holes are opened at the bottom of the pressing plate 9. The outer wall of the spiral groove of the lead screw 10 contacts the inner wall of the pressing plate 9. The outer wall of the elastic telescopic rod 12 movably penetrates through the inside of the pressing plate 9. A torsion spring is arranged between the inside of the round rod 14 and the inclined push plate 15. On the right side of the extension component 7, there is an anti-concave and convex device 4 for removing dirt or attachments on the inner side (i.e., the wound part) of the non-woven fabric.

[0024] During use, the non-woven fabric roller is sleeved on the outer wall of the socket rod 32. The staff pulls one end of the non-woven fabric and places it on the top plane of the stretching component 7. Then, the screw rod 10 is rotated. When the screw rod 10 rotates, through the restriction of the spiral groove on its outer wall on the internal block of the pressing plate 9, and the continuous contact of the block with the inner wall of the spiral groove of the screw rod 10, the pressing plate 9 can slide downward along the outer wall of the screw rod 10. The back of the pressing plate 9 is restricted by the vertical plate 8, so that the pressing plate 9 can slide stably downward along the front of the vertical plate 8. After the pressing plate 9 stably presses non-woven fabrics of different thicknesses, the staff inserts the round column into the limit hole of the rotating component 31 to limit the rotating component 31. At the same time, the pressing component 33 slides downward along the inner wall of the L-shaped fixing component 3 to press the non-woven fabric roller to make it stationary. Through the above cooperation, relying on the flat pressing of the wide area at the bottom of the pressing plate 9, the stability during the stretching process is ensured. At the same time, the pressing plate 9 can achieve a good stable pressing effect on non-woven fabrics of different thicknesses through the screw rod 10, improving the practicability of the detection component 2 for elastic detection of different types of non-woven fabrics. At the same time, when the pressing plate 9 descends, the pressing plate 9 drives the round rod 14 and the inclined push plate 15 to move synchronously. Since the inclined push plate 15 is longer than the elastic telescopic rod 12 and the positioning rubber plate 13, the inclined push plate 15 contacts the top of the non-woven fabric first. Through the arc surface at the bottom of the inclined push plate 15 and its inclination angle, the inclined push plate 15 can push along the top of the non-woven fabric away from the center of the pressing plate 9. At this time, the inclined push plate 15 starts to rotate along the outer wall of the round rod 14 until the inclined push plate 15 fits into the internal return groove of the pressing plate 9. Then, the bottom of the positioning rubber plate 13 contacts and positions the four corners of the top of the non-woven fabric. As the pressing plate 9 continues to descend, the contact force causes the telescopic end of the elastic telescopic rod 12 to contract upward. When the telescopic end of the elastic telescopic rod 12 contracts to the bottom, the whole elastic telescopic rod 12 slides upward and the contact elastic piece 11 deforms. At this time, the positioning rubber plate 13 fits into the internal round hole at the bottom of the pressing plate 9. The electric slide rail 34 is started, and the electric slide rail 34 drives the transmission column 6 to slide leftward inside itself. The transmission column 6 drives the stretching component 7 to slide synchronously along the bottom of the inner wall of the detection component 2. The stretching component 7 pulls the elastic detection part of the non-woven fabric to move and stretch synchronously. The stretching distance generated during the pulling process of the stretching component 7 is converted into elastic detection data by the stretching component 7. Then, the detection signal source is transmitted to the display component 21 through the intelligent module and displayed by the display component 21 for the staff to record. Through the above cooperation, relying on the inclined push plate 15 to smooth the wrinkles existing at the clamped and stretched end of the non-woven fabric, and at the same time, after the wrinkles are smoothed, the positioning rubber plate 13 positions the four corners of the non-woven fabric to prevent the non-woven fabric from sliding and shifting under external interference and detaching from the central part of the stretching component 7. And both the positioning rubber plate 13 and the inclined push plate 15 can fit into the pressing plate 9 to ensure that the bottom of the pressing plate 9 contacts the non-woven fabric in a flat posture, effectively ensuring that the clamping area of the clamped end of the non-woven fabric will not shrink, thus preventing the stretching and falling-off phenomenon, and avoiding certain wrinkles and twists in the overall detection part of the non-woven fabric, which may affect the detection result.

[0025] Please refer toFigures 1-9 , on the basis of the above embodiments, in another embodiment of the present invention, an anti-convexity device 4 is further included; According to the above technical solution, the anti-convexity device 4 includes two cross plates 41, a rotating wheel 42, a rotating rod 43, a plurality of U-shaped hollow frames 44, a top plate 45, a trapezoidal plate 46, a contact plate 47 and a sliding rod 48. The left sides of the two cross plates 41 are fixedly installed on the right side of the stretching assembly 7. The side of the rotating wheel 42 away from the center of the stretching assembly 7 is rotatably installed on the inner wall of the cross plate 41. The front and back ends of the rotating rod 43 are fixedly installed at the center of the inner wall of the rotating wheel 42. A reciprocating spiral groove is opened at one end of the back of the rotating rod 43. A plurality of U-shaped hollow frames 44 are fixedly installed on the outer surface of the rotating rod 43. The front side of the top plate 45 is vertically slidably installed on the front inner wall of the U-shaped hollow frame 44 through a spring. The trapezoidal plate 46 is internally penetrated and slidably installed inside the U-shaped hollow frame 44. The contact plate 47 is internally penetrated and slidably installed on the outer wall of the reciprocating spiral groove of the rotating rod 43. The right end of the sliding rod 48 is fixedly installed on the left side of the contact plate 47. Through the above cooperation, the bottom of the non-woven fabric, that is, the side that is wound around each other on the roller, is rotated and scraped, and the non-woven fabric is indirectly pushed by the top plate 45 to cause it to bulge intermittently, so as to realize that the non-woven fabric can be evenly stretched before static detection, ensure the tightness of stretching and avoid loosening, which may lead to errors in the detection results. At the same time, ensure the cleanliness of the bottom of the non-woven fabric to avoid the non-woven fabric being closely adhered to each other when recycling and winding.

[0026] According to the above technical solution, the outer wall of the rotating wheel 42 contacts the bottom inner wall of the detection assembly 2. A plurality of U-shaped hollow frames 44 are equidistantly distributed on the outer wall of the rotating rod 43. The arc surface at the bottom of the top plate 45 is located on the movement track of the inclined surface of the trapezoidal plate 46. The front surface of the contact plate 47 contacts the back surface of the trapezoidal plate 46. The left end of the sliding rod 48 is slidably connected to the right side of the stretching assembly 7. A anti-fluctuation device 5 for ensuring the constant temperature of the non-woven fabric itself during elastic stretching detection is arranged on the left side of the U-shaped hollow frame 44.

[0027] According to the above technical solution, the anti-convexity device 4 further includes a plurality of U-shaped plates 49 and a receiving plate 410. The bottom inner walls of the plurality of U-shaped plates 49 are fixedly installed on the bottom of the top plate 45. The plurality of U-shaped plates 49 are symmetrically distributed with the axis of the top plate 45 as the center. The top of the receiving plate 410 is hinged to the outer wall of the U-shaped hollow frame 44 through a torsion spring. The inclined surface of the receiving plate 410 contacts the top of the U-shaped plate 49. Through the above cooperation, the receiving range of the receiving plate 410 for dirt is expanded, and the solid particle dirt scraped off by the receiving plate 410 from the U-shaped hollow frame 44 is received in real time, preventing the particulate matter from flying around and adhering to the rest of the area of the non-woven fabric when it falls due to the impact of rotating parts such as the top plate 45.

[0028] During use, when the stretching component 7 moves to the left, it drives the cross plate 41 to move synchronously. The cross plate 41 drives the rotating wheel 42 to move synchronously. The outer wall of the rotating wheel 42 contacts the bottom of the inner wall of the detection component 2 to generate frictional force. The rotating wheel 42 starts to rotate due to the frictional force and drives the rotating rod 43 to rotate. The rotating rod 43 drives the loop-shaped hollow frame 44 to rotate. When the loop-shaped hollow frame 44 rotates, it rotates and scrapes the bottom of the non-woven fabric. At the same time, the loop-shaped hollow frame 44 drives the top plate 45 to move synchronously. When the rotating rod 43 rotates, the restriction of the built-in block of the contact plate 47 by the reciprocating spiral groove on its outer wall enables the contact plate 47 to slide forward and reset along the outer wall of the reciprocating spiral groove of the rotating rod 43. The contact plate 47 drives the sliding rod 48 to slide along the right side of the stretching component 7. When the contact plate 47 slides forward, it drives the trapezoidal plate 46 to move synchronously. And the trapezoidal plate 46 will only be pushed and contacted by the contact plate 47 when it rotates above the outer wall of the rotating rod 43. The trapezoidal plate 46 slides synchronously along the inside of the loop-shaped hollow frame 44 through the contact force. At this time, the trapezoidal plate 46 contacts the arc surface of the top plate 45 to cause the top plate 45 to generate an upward movement force. The top plate 45 slides upward along the inner wall of the loop-shaped hollow frame 44 and contacts the non-woven fabric during stretching. Through the above cooperation, the bottom of the non-woven fabric, that is, the side that is wound around each other on the roller, is rotated and scraped. And the non-woven fabric is indirectly pushed by the top plate 45 to cause it to bulge intermittently, realizing that the non-woven fabric can be evenly stretched before static detection, ensuring the tightness of stretching to avoid loosening and resulting in errors in the detection results. At the same time, ensuring the cleanliness of the bottom of the non-woven fabric to avoid the non-woven fabrics being closely attached to each other when they are wound back; when the top plate 45 moves upward, it drives the U-shaped plate 49 to move synchronously. When the U-shaped plate 49 moves upward, the top of it contacts the inclined surface of the receiving plate 410 to generate an upward contact force. At this time, the hinge shaft between the receiving plate 410 and the loop-shaped hollow frame 44 starts to rotate. The receiving plate 410 moves upward in an arc-shaped trajectory parallel to the top plate 45. Through the above cooperation, the receiving range of the receiving plate 410 for dirt is expanded. The receiving plate 410 is relied on to receive the solid particle dirt scraped off by the loop-shaped hollow frame 44 in real time, preventing the particulate matter from flying around and adhering to the rest of the area of the non-woven fabric when it falls due to the impact of rotating components such as the top plate 45.

[0029] Please refer to Figures 1-9 , on the basis of the above embodiments, in another embodiment of the present invention, a anti-fluctuation device 5 is further included; According to the above technical solution, the anti-fluctuation device 5 includes two L-shaped plates 51, a return-shaped plate 52 and a hot air assembly 53. The left sides of the two L-shaped plates 51 are slidably installed on the right side of the stretching assembly 7. The L-shaped plates 51 penetrate and are fixedly installed on the outer wall of the sliding rod 48. The front and back sides of the return-shaped plate 52 are fixedly installed between the outer walls of the two L-shaped plates 51. The back of the hot air assembly 53 is fixedly installed on the front of the L-shaped plate 51. Through the above cooperation, while ensuring that the hot air assembly 53 blows air on the non-woven fabric in real time, the movement range of the hot air assembly 53 is expanded to avoid fixed-point blowing, so that the non-woven fabric is evenly heated and stretched, and it is prevented that the non-woven fabric is eroded by moisture during the production process, resulting in an increase in the fiber softness and thus a decrease in the elastic value.

[0030] According to the above technical solution, the anti-fluctuation device 5 further includes a transmission rod 54 and a plurality of flapping plates 55. Both ends of the front of the transmission rod 54 penetrate and are rotatably installed on the inner wall of the cross plate 41. A spiral groove is formed at one end of the back of the transmission rod 54, and the spiral groove is located on the movement track inside the L-shaped plate 51. A plurality of flapping plates 55 are equidistantly and fixedly installed on the outer wall of the transmission rod 54.

[0031] According to the above technical solution, the anti-fluctuation device 5 further includes a fixing ring 56, a telescopic column 57, a cam 58 and an L-shaped cover plate 59. The back of the fixing ring 56 is fixedly installed on the front of the flapping plate 55. One end of the front of the telescopic column 57 is fixedly installed on the back of the fixing ring 56. The back of the cam 58 is rotatably installed on the front of the outer wall of the L-shaped plate 51. The front of the cam 58 is fixedly installed on the back of the telescopic end of the telescopic column 57. The back of the L-shaped cover plate 59 is vertically slidably installed on the front of the L-shaped plate 51 through a spring, and a round block is fixedly installed on the top of the L-shaped cover plate 59. The outer wall of the round block is in contact with the outer wall of the cam 58. Through the above cooperation, relying on the flapping plate 55, the hot air flow and the moisture evaporated when the non-woven fabric is heated are quickly disturbed and mixed, ensuring a dry detection environment while ensuring that the non-woven fabric is evenly heated and avoiding the occurrence of uniform high temperature phenomenon. At the same time, the L-shaped cover plate 59 shields the top of the hot air assembly 53 to prevent dirt from entering and guides the air flow deposited below the L-shaped plate 51, improving the overall temperature of the internal space of the detection assembly 2 and reducing the temperature difference.

[0032] During use, when the sliding rod 48 slides forward and resets, it drives the L-shaped plate 51 to slide synchronously along the right side of the stretching component 7. The two L-shaped plates 51 slide synchronously through the loop-shaped plate 52, and the L-shaped plate 51 drives the hot air component 53 to move synchronously. Through the above cooperation, while ensuring that the hot air component 53 blows air on the non-woven fabric in real time, the activity range of the hot air component 53 is expanded to avoid blowing at a fixed point, so that the non-woven fabric is uniformly heated and stretched as a whole, and prevent the non-woven fabric from being eroded by moisture during the production process, resulting in an increase in the softness of the fibers and a decrease in the elastic value. When the L-shaped plate 51 slides along the outer wall of the non-self-locking spiral groove of the transmission rod 54, the restriction of the inner wall of the spiral groove by the built-in block of the L-shaped plate 51 causes the transmission rod 54 to generate a rotational force and start to rotate. The transmission rod 54 drives the fan plate 55 to rotate. When the fan plate 55 rotates, it rotates and disturbs the air flow within the heating range at the bottom of the non-woven fabric. At the same time, the fan plate 55 drives the fixed ring 56 to rotate, the fixed ring 56 drives the telescopic column 57 to rotate, and the telescopic column 57 drives the cam 58 to rotate along the outer wall of the L-shaped plate 51. When the cam 58 rotates, it touches the round block at the top of the L-shaped cover plate 59, causing it to generate an upward movement force. The round block drives the L-shaped cover plate 59 to move upward along the outer wall of the L-shaped plate 51. Due to the elastic force restriction of the spring, the round block always clings to the outer wall of the cam 58. Thus, the L-shaped cover plate 59 can reciprocate up and down. Through the above cooperation, relying on the fan plate 55 to quickly disturb and mix the heat flow and the moisture evaporated when the non-woven fabric is heated, while ensuring a dry detection environment, it also ensures that the non-woven fabric is uniformly heated and avoids the occurrence of uniform high temperature phenomenon. At the same time, the L-shaped cover plate 59 shields the top of the hot air component 53 to prevent dirt from entering, and at the same time guides the air flow deposited below the L-shaped plate 51, improving the overall temperature of the internal space of the detection component 2 and reducing the temperature difference.

[0033] A method for using a non-woven fabric elastic detection device for textile production, comprising the following steps: S1: The non-woven fabric roller is sleeved on the outer wall of the socket rod 32. The staff pulls one end of the non-woven fabric and places it on the top plane of the stretching component 7, and rotates the lead screw 10. When the lead screw 10 rotates, through the restriction of the inner wall of the spiral groove on the outer wall of the lead screw 10 on the internal block of the pressing plate 9, and the continuous contact of the block with the inner wall of the spiral groove of the lead screw 10, the pressing plate 9 can slide downward along the outer wall of the lead screw 10. The back of the pressing plate 9 is restricted by the vertical plate 8, so that the pressing plate 9 can slide stably downward along the front of the vertical plate 8. S2: After the pressing plate 9 stably presses non-woven fabrics of different thicknesses, the staff inserts the round column into the limit hole of the rotating component 31 to limit the rotating component 31. At the same time, the pressing component 33 slides downward along the inner wall of the L-shaped fixing component 3 to press the non-woven fabric roller to ensure its static state. S3: Meanwhile, when the pressing plate 9 descends, the pressing plate 9 drives the round rod 14 and the inclined push plate 15 to move synchronously. Since the inclined push plate 15 is longer than the elastic telescopic rod 12 and the positioning rubber plate 13, it causes the inclined push plate 15 to come into contact with the top of the non-woven fabric first. Due to the arc surface at the bottom of the inclined push plate 15 and its own inclination angle, the inclined push plate 15 can push along the top of the non-woven fabric away from the center of the pressing plate 9. At this time, the inclined push plate 15 starts to rotate along the outer wall of the round rod 14 until the inclined push plate 15 fits into the internal return groove of the pressing plate 9. After that, the bottom of the positioning rubber plate 13 contacts and positions and presses the four corners of the top of the non-woven fabric. As the pressing plate 9 continues to descend, the resistance force causes the telescopic end of the elastic telescopic rod 12 to contract upward. When the telescopic end of the elastic telescopic rod 12 contracts to the bottom, the whole elastic telescopic rod 12 slides upward and the contact elastic piece 11 deforms. At this time, the positioning rubber plate 13 fits into the internal round hole at the bottom of the pressing plate 9; S4: Start the electric slide rail 34. The electric slide rail 34 drives the transmission column 6 to slide leftward inside itself. The transmission column 6 drives the stretching component 7 to slide synchronously along the bottom of the inner wall of the detection component 2. The stretching component 7 pulls the elastic detection part of the non-woven fabric to move and stretch synchronously. The stretching distance generated during the pulling process of the stretching component 7 is converted into elastic detection data by the stretching component 7. Then, the detection signal source is transmitted to the display component 21 through the intelligent module and is displayed by the display component 21 for the convenience of the staff to record.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
