Description

Technical Field

[0001] The invention relates to the technical field of elasticity detection, and in particular to a device and method for detecting elasticity of non-woven fabrics used in textile production. Background Art

[0002] With the development of science and technology, the testing technology for textiles in the production process of textile products has gradually developed. In order to ensure the final product effect of textile products, it is necessary to sample the products of each process section in the textile production process for performance testing. Non-woven fabrics are no exception, and elasticity testing is an important part of it.

[0003] The patent with the patent announcement number CN218847818U discloses a non-woven fabric elasticity detection device for textile production, including a fabric elasticity detection base, a support arm, a fabric elasticity data control board, an electric slide, a fabric elasticity pulling seat, a fabric elasticity fixing seat, a fabric electric clamp, a protective mechanism and a fabric waste dust collection mechanism; the top of the fabric elasticity detection base is fixedly installed with a support arm, and the front side of the support arm is fixedly installed with a fabric elasticity data control board. The patent sets a protective mechanism to protect the device components for detecting the elasticity of non-woven fabrics, and to prevent the non-woven fabrics from breaking and injuring people when the non-woven fabrics are pulled for detection. In addition, the L-shaped cover of the protective mechanism can be disassembled and assembled by removing the screws, which is convenient for the maintenance of the internal components. The fabric waste dust collection mechanism is set to suck away and collect the thread ends and fluff in the protective cover, which is convenient for cleaning the components of the detection device.

[0004] However, the device still has some shortcomings: the device detects the elasticity of the non-woven fabric while preventing the non-woven fabric from breaking and injuring people. However, the clamping ends of the non-woven fabric are prone to wrinkles during the clamping and stretching process. When the clamping ends of the non-woven fabric are wrinkled, the clamping area is reduced, thereby reducing the clamping strength and increasing the risk of the clamping end falling off. In addition, 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, thereby affecting the detection result. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a device and method for detecting elasticity of non-woven fabrics for textile production, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a non-woven fabric elasticity detection device for textile production, comprising a base, a detection component is arranged on the top of the base, the interior of the detection component is hollow, a display component is arranged above the front of the detection component, an L-shaped fixed component is arranged on the right side of the interior of the detection component, a rotating component is arranged on the back of the inner wall of the L-shaped fixed component, a plurality of limiting holes are provided inside the rotating component, a sleeve rod is arranged at the center of the front of the rotating component, a pressing component is arranged on the right side of the interior of the L-shaped fixed 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 connected with the display component through an intelligent module, and the bottom of the stretching component is in contact with 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 round-shaped grooves are provided inside the pressing plate, and the two round-shaped grooves are centered on the pressing plate axis Symmetrically distributed, a screw is rotatably installed on the left side of the stretching component, and a plurality of spring sheets are fixedly installed at the top edge of the pressure plate, and elastic telescopic rods are fixedly installed on the top concave surfaces of the inner walls of the plurality of spring sheets, and a positioning rubber plate is fixedly installed on the bottom of the telescopic end of the elastic telescopic rod, and a round rod is fixedly installed on the inner wall of the press plate's round groove, and an inclined push plate is penetrated and rotatably installed on the outer wall of the round rod, and 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 and rotates the screw. When the screw rotates, the spiral groove of its own outer wall limits the block inside the pressure plate, and the block constantly contacts the inner wall of the spiral groove of the screw, so that the pressure plate can slide downward along the outer wall of the screw, and the back of the pressure plate is limited by the vertical plate, so that the pressure plate can slide steadily downward along the front of the vertical plate. After the pressure plate stably presses non-woven fabrics of different thicknesses, the staff inserts the circular 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 it is stationary;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. The inclined push plate is pushed away from the center of the pressing plate along the arc surface at the bottom of the inclined push plate and its own inclination angle. At this time, the inclined push plate begins to rotate along the outer wall of the round rod until the inclined push plate fits into the inner part of the circular groove of the pressing plate. After that, the bottom of the positioning rubber plate contacts the four corners of the top of the non-woven fabric and positions and presses. As the pressing plate continues to descend, the resistance force causes the telescopic end of the elastic telescopic rod to retract upward. When the elastic telescopic rod is extended, After the shrinking end is retracted to the bottom, the elastic telescopic rod slides upward as a whole and resists the deformation of the spring sheet. At this time, the positioning rubber plate fits inside the circular hole at the bottom of the pressure plate, and the electric slide rail is started. The electric slide rail 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 during the pulling process of the stretching component is converted into elastic detection data by the stretching component, and then the detection signal source is transmitted to the display component through the intelligent module, and the display is displayed by the display component to facilitate the staff to record. ;

[0007] According to the above technical solution, a plurality of circular holes are provided at the bottom of the pressing plate, the outer wall of the spiral groove of the screw rod contacts the inner wall of the pressing plate, the outer wall of the elastic telescopic rod movably passes through the interior of the pressing plate, a torsion spring is provided between the interior of the circular rod and the inclined push plate, and an anti-convex and concave device for removing dirt or attachments on the inner side of the non-woven fabric, i.e., the entangled part, is provided on the right side of the stretching assembly.

[0008] According to the above technical scheme, the anti-convex and concave device includes two horizontal plates, a rotating wheel, a rotating rod, a plurality of circular hollow frames, a top plate, a trapezoidal plate, a contact plate and a sliding rod. The left sides of the two horizontal plates are fixedly installed on the right side of the stretching component, and the rotating wheel is rotatably installed on the inner wall of the horizontal plate away from the center of the stretching component. Both 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 opened at one end of the back of the rotating rod. Several circular hollow frames are fixedly installed on the outer wall surface of the rotating rod. One side of the front of the top plate is vertically slidably installed on the front of the inner wall of the circular hollow frame through a spring. The trapezoidal plate passes through and is slidably installed inside the circular hollow frame. The contact plate passes through and is 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 horizontal plate to move synchronously, and the horizontal 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 friction. The rotating wheel starts to rotate through the friction force and drives the rotating rod to rotate. The rotating rod drives the circular hollow frame to rotate. When the circular hollow frame rotates, it rotates and scrapes with the bottom of the non-woven fabric. At the same time, the circular hollow frame drives the top plate to move synchronously. When the rotating rod rotates, the reciprocating spiral groove on its own outer wall restricts the built-in block of the resistance plate, so that the resistance plate can slide forward and reset along the outer wall of the reciprocating spiral groove of the rotating rod. The resistance plate drives the sliding rod to slide along the right side of the stretching component. When the resistance plate slides forward, it resists the trapezoidal plate for synchronous movement, and the trapezoidal plate will only be pushed and resisted by the resistance plate when it rotates to above the outer wall of the rotating rod. The trapezoidal plate slides synchronously along the inside of the circular hollow frame through the resistance force. At this time, the trapezoidal plate resists the arc surface of the top plate, prompting the top plate to generate an upward movement force. The top plate slides upward along the inner wall of the circular hollow frame and resists the non-woven fabric during the stretching process.

[0009] According to the above technical solution, the outer wall of the rotating wheel contacts the bottom of the inner wall of the detection assembly, a number of the circular 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 inclined motion trajectory of the trapezoidal plate, the front of the resistance plate contacts the back of the trapezoidal plate, the left end of the sliding rod is slidably connected to the right side of the stretching assembly, and the left side of the circular hollow frame is provided with an anti-fluctuation device for ensuring that the temperature of the non-woven fabric remains constant during elastic stretching testing.

[0010] According to the above technical scheme, the anti-convex and concave device also includes a plurality of U-shaped plates and a receiving plate. The bottoms of the inner walls of the plurality of U-shaped plates are fixedly installed on the bottom of the top plate. The plurality of U-shaped plates are symmetrically distributed around the axis of the top plate. The top of the receiving plate is hinged to the outer wall of the circular 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 contacts the inclined surface of the receiving plate to generate an upward resistance force. At this time, the hinge shaft between the receiving plate and the circular hollow frame starts to rotate, and the receiving plate moves upward in an arc trajectory parallel to the top plate.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] A method for using a nonwoven 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.

[0015] 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.

[0016] (2) The present invention realizes the rotational scraping of the bottom of the non-woven fabric, i.e., the side of the non-woven fabric that is wound around each other on the roller, by setting up an anti-convex and concave device through the cooperation of a stretching assembly, a horizontal plate, a rotating wheel, a rotating rod, a circular hollow frame, a top plate, a trapezoidal plate, a contact plate, a sliding rod, a U-shaped plate and a receiving plate, and indirectly pushes the non-woven fabric through the top plate to cause it to indirectly bulge, so that the non-woven fabric can be stretched evenly before static detection, ensuring the tightness of the stretching to avoid looseness that causes errors in the detection results, and at the same time ensuring the cleanliness of the bottom of the non-woven fabric to avoid close contact with each other during recycling and winding; and expanding the receiving range of the receiving plate for dirt, relying on the receiving plate to receive the solid particle dirt that falls off the circular hollow frame by scraping, to prevent the particle from being hit by the rotating parts such as the top plate when falling and flying around and adhering to the remaining area of ​​the non-woven fabric.

[0017] (3) The present invention adopts the arrangement of an anti-fluctuation device, and cooperates with a sliding rod, an L-shaped plate, a circular plate, a hot air assembly, a transmission rod, a fan plate, a fixed ring, a telescopic column, a cam and an L-shaped cover plate to ensure that the hot air assembly blows air to the non-woven fabric in real time, while expanding the activity range of the hot air assembly to avoid fixed-point blowing, so that the non-woven fabric is heated and stretched uniformly as a whole, and the non-woven fabric is prevented from being eroded by moisture during the production process, which increases the softness of the fiber and reduces the elasticity value; and relies on the fan plate to quickly disturb and mix the heat flow with the moisture evaporated when the non-woven fabric is heated, so as to ensure a dry detection environment while ensuring that the non-woven fabric is heated uniformly to avoid the occurrence of uniform high temperature. At the same time, the L-shaped cover plate blocks the top of the hot air assembly to prevent dirt from entering, and at the same time guides the airflow deposited under the L-shaped plate, thereby increasing the overall temperature of the internal space of the detection assembly and reducing the temperature difference.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-Figure 9One embodiment of the present invention is: a non-woven fabric elasticity detection device for textile production, comprising a base 1, a detection component 2 is arranged on the top of the base 1, the detection component 2 is hollow inside, a display component 21 is arranged above the front of the detection component 2, an L-shaped fixing component 3 is arranged on the right side inside the detection component 2, a rotating component 31 is arranged on the back of the inner wall of the L-shaped fixing component 3, a plurality of limiting holes are opened inside the rotating component 31, a sleeve rod 32 is arranged at the center of the front of the rotating component 31, a pressing component 33 is arranged on the right side inside the L-shaped fixing component 3, and the inner wall of the detection component 2 is provided with a plurality of limiting holes, a sleeve rod 32 is arranged at the center of the front of the rotating component 31, a pressing component 33 is arranged on the right side inside the L-shaped fixing component 3, and a plurality of limiting holes are opened inside the rotating component 31. An electric slide rail 34 is arranged on the back, a transmission column 6 is slidably installed inside the electric slide rail 34, a stretching component 7 is fixedly installed on the outer wall of the transmission column 6, the stretching component 7 is connected with the display component 21 through the intelligent module, and the bottom of the stretching component 7 is in contact with the bottom of the inner wall of the detection component 2, a vertical plate 8 is fixedly installed on the top edge of the stretching component 7, a pressing plate 9 is slidably installed on the front of the vertical plate 8, two return grooves are arranged inside the pressing plate 9, and the two return grooves are symmetrically distributed with respect to the axis of the pressing plate 9, a screw rod 10 is rotatably installed on the left side inside the stretching component 7, and a plurality of spring pieces are fixedly installed on the top edge of the pressing plate 9 11, the concave surfaces at the top of the inner walls of the plurality of spring sheets 11 are fixedly installed with elastic telescopic rods 12, the bottom of the telescopic ends of the elastic telescopic rods 12 are fixedly installed with positioning rubber plates 13, the inner wall of the circular groove of the pressing plate 9 is fixedly installed with round rods 14, and the outer wall of the round rods 14 is penetrated and rotatably installed with oblique push plates 15. Through the above cooperation, the stability of the stretching process is ensured by flattening a wide area of ​​the bottom of the pressing plate 9. At the same time, the pressing plate 9 has a good stable pressing effect for non-woven fabrics of different thicknesses through the screw rod 10, thereby improving the practicality of the detection component 2 for elastic detection of different types of non-woven fabrics; The above cooperation relies on the inclined push plate 15 to smooth out the wrinkles at one end of the non-woven fabric clamping and stretching. At the same time, the positioning rubber plate 13 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 under external interference and detaching from the center part of the stretching component 7. In addition, the positioning rubber plate 13 and the inclined push plate 15 can both fit into the inside of 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 clamping end of the non-woven fabric will not be reduced, 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, thereby affecting the detection result.

[0022] According to the above technical scheme, a plurality of circular holes are opened at the bottom of the pressing plate 9, the outer wall of the spiral groove of the screw rod 10 contacts the inner wall of the pressing plate 9, the outer wall of the elastic telescopic rod 12 movably passes through the interior of the pressing plate 9, a torsion spring is arranged between the interior of the round rod 14 and the inclined push plate 15, and an anti-convex and concave device 4 for removing dirt or attachments on the inner side of the non-woven fabric, i.e., part of the entangled part, is arranged on the right side of the stretching assembly 7.

[0023] When in use, the non-woven fabric roller is sleeved on the outer wall of the sleeve rod 32, and 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 screw rod 10. When the screw rod 10 rotates, the spiral groove on its outer wall limits the block inside the pressure plate 9, and the block constantly contacts the inner wall of the spiral groove of the screw rod 10, so that the pressure plate 9 can slide downward along the outer wall of the screw rod 10. The back of the pressure plate 9 is restricted by the vertical plate 8, so that the pressure plate 9 can slide downward stably along the front of the vertical plate 8. After the pressure plate 9 stably presses non-woven fabrics of different thicknesses, the staff inserts the circular column into the limiting hole of the rotating component 31 to limit the rotating component 31, and 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 keep it stable. To ensure stillness, the above cooperation relies on the flat pressing of a wide area at the bottom of the pressing plate 9 to ensure stability during the stretching process. At the same time, the pressing plate 9 achieves a good stable pressing effect for non-woven fabrics of different thicknesses through the screw rod 10, thereby improving the practicality 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 is prompted to contact the top of the non-woven fabric first, and the inclined push plate 15 is pushed away from the center of the pressing plate 9 along the top of the non-woven fabric through the arc surface at the bottom of the inclined push plate 15 and its own inclination angle. 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 inside the circular groove of the pressing plate 9, and 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 resistance force causes the telescopic end of the elastic telescopic rod 12 to shrink upward. When the telescopic end of the elastic telescopic rod 12 shrinks to the bottom, the elastic telescopic rod 12 slides upward as a whole and deforms the resisting spring sheet 11. At this time, the positioning rubber plate 13 fits inside the circular hole at the bottom of the pressing plate 9, and the electric slide rail 34 is started. The electric slide rail 34 drives the transmission column 6 to slide to the left inside itself, and 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 synchronously and stretch. The stretching distance generated during the pulling process of the stretching component 7 is converted into elastic The detection data is then transmitted to the display component 21 through the intelligent module, and the display component 21 is used for display to facilitate the staff to record. Through the above cooperation, the inclined push plate 15 is used to smooth out the wrinkles at one end of the non-woven fabric clamping and stretching. At the same time, the positioning rubber plate 13 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 component 7 under the interference of external forces, and the positioning rubber plate 13 and the inclined push plate 15 can both fit into the inside of the pressing plate 9 to ensure that the bottom of the pressing plate 9 contacts the non-woven fabric in a planar 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 off phenomenon from occurring, and avoiding certain wrinkles and twists in the overall detection part of the non-woven fabric, thereby affecting the detection result.

On the front of the inner wall, the trapezoidal plate 46 penetrates and is slidably installed inside the circular hollow frame 44, the contact plate 47 penetrates and is slidably installed on the outer wall of the reciprocating spiral groove of the rotating rod 43, and 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 mutually wound on the roller, is rotated and scraped, and the non-woven fabric is indirectly pushed by the top plate 45 to cause it to indirectly bulge, so that the non-woven fabric can be stretched evenly before static detection, ensuring the tightness of the stretching to avoid looseness and causing errors in the detection results, and at the same time ensuring the cleanliness of the bottom of the non-woven fabric to avoid close adhesion when recycling and winding.

[0025] According to the above technical scheme, the outer wall of the rotating wheel 42 contacts the bottom of the inner wall of the detection component 2, a number of circular hollow frames 44 are equidistantly distributed on the outer wall of the rotating rod 43, the bottom arc surface of the top plate 45 is located on the inclined motion trajectory of the trapezoidal plate 46, the front of the resistance plate 47 contacts the back of the trapezoidal plate 46, the left end of the sliding rod 48 is slidably connected to the right side of the stretching component 7, and the left side of the circular hollow frame 44 is provided with an anti-fluctuation device 5 for ensuring that the temperature of the non-woven fabric remains constant during elastic stretching detection.

[0026] According to the above technical scheme, the anti-bump device 4 also includes a plurality of U-shaped plates 49 and a receiving plate 410. The bottom of the 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 around the axis of the top plate 45. The top of the receiving plate 410 is hinged to the outer wall of the circular hollow frame 44 through a torsion spring. The inclined surface of the receiving plate 410 contacts the top of the U-shaped plate 49. The above coordination expands the receiving range of the receiving plate 410 for dirt. The receiving plate 410 is used to receive the solid particle dirt scraped and dropped by the circular hollow frame 44 in real time, so as to prevent the particles from being hit by rotating parts such as the top plate 45 when falling and scattering everywhere and adhering to the remaining area of ​​the non-woven fabric.

[0027] When in use, the stretching component 7 moves to the left and drives the horizontal plate 41 to move synchronously, and the horizontal 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 friction. The rotating wheel 42 starts to rotate through the friction and drives the rotating rod 43 to rotate. The rotating rod 43 drives the circular hollow frame 44 to rotate. When the circular hollow frame 44 rotates, it rotates and scrapes the bottom of the non-woven fabric. At the same time, the circular hollow frame 44 drives the top plate 45 to move synchronously. When the rotating rod 43 rotates, the reciprocating spiral groove on its outer wall contacts the limit block built in the contact plate 47. The contact plate 47 is controlled to slide forward and reset along the outer wall of the reciprocating spiral groove of the rotating rod 43, and the contact plate 47 drives the sliding rod 48 to slide along the right side of the stretching assembly 7.

The trapezoidal plate 46 slides synchronously along the inside of the circular hollow frame 44 through the resistance force. At this time, the trapezoidal plate 46 resists the arc surface of the top plate 45, causing the top plate 45 to generate a force to move upward, and the top plate 45 moves along the circular hollow frame 44. The inner wall of the U-shaped hollow frame 44 slides upward and resists the non-woven fabric in the stretching process. 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 top plate 45 indirectly pushes the non-woven fabric to cause it to bulge indirectly, so that the non-woven fabric can be stretched evenly before static testing, ensuring the tightness of the stretching to avoid looseness that causes errors in the test results, and at the same time ensuring the cleanliness of the bottom of the non-woven fabric to avoid close contact with each other during recycling and winding; when the top plate 45 moves upward, it drives the U-shaped plate 49 to move synchronously, and the U-shaped When the plate 49 moves upward, the top contacts the inclined surface of the receiving plate 410 to generate an upward resistance force. At this time, the hinge shaft between the receiving plate 410 and the circular hollow frame 44 begins to rotate, and the receiving plate 410 moves upward in an arc trajectory parallel to the top plate 45. Through the above cooperation, the receiving plate 410 can expand the receiving range of dirt, and rely on the receiving plate 410 to receive the solid particle dirt scraped and dropped by the circular hollow frame 44 in real time, preventing the particles from being hit by the rotating parts such as the top plate 45 when falling and scattering everywhere and adhering to the remaining area of ​​the non-woven fabric.

The left sides of the two L-shaped plates 51 are slidably installed on the right side of the stretching component 7. The inside of the L-shaped plate 51 passes through and is fixedly installed on the outer wall of the sliding rod 48. The front and back sides of the circular plate 52 are fixedly installed between the outer walls of the two L-shaped plates 51. The back of the hot air component 53 is fixedly installed on the front of the L-shaped plate 51. Through the above cooperation, the hot air component 53 is guaranteed to blow the non-woven fabric in real time, while expanding the activity range of the hot air component 53 to avoid fixed-point blowing, so that the non-woven fabric is heated and stretched uniformly as a whole, and the non-woven fabric is prevented from being eroded by moisture during the production process, which increases the softness of the fiber and reduces the elasticity value.

[0029] According to the above technical solution, the anti-wave device 5 also includes a transmission rod 54 and a plurality of fan plates 55. Both ends of the front side of the transmission rod 54 penetrate and are rotatably installed on the inner wall of the horizontal plate 41. A spiral groove is opened at one end of the back side of the transmission rod 54. The spiral groove is located on the internal motion trajectory of the L-shaped plate 51. The plurality of fan plates 55 are equidistant and fixedly installed on the outer wall of the transmission rod 54.

[0030] According to the above technical scheme, the anti-fluctuation device 5 also includes a fixed ring 56, a telescopic column 57, a cam 58 and an L-shaped cover plate 59. The back of the fixed ring 56 is fixedly installed on the front of the fan plate 55, one end of the front of the telescopic column 57 is fixedly installed on the back of the fixed 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, the fan plate 55 is relied on to quickly disturb and mix the heat flow and the moisture evaporated when the non-woven fabric is heated, to ensure a dry detection environment while ensuring that the non-woven fabric is evenly heated to avoid the occurrence of uniform high temperature, at the same time, the L-shaped cover plate 59 blocks the top of the hot air component 53 to prevent dirt from entering, and at the same time guides the airflow deposited under the L-shaped plate 51, thereby increasing the overall temperature of the internal space of the detection component 2 and reducing the temperature difference.

[0031] When in use, the sliding rod 48 slides forward and resets, driving the L-shaped plate 51 to slide synchronously along the right side of the stretching component 7, and the two L-shaped plates 51 slide synchronously through the return plate 52, and the L-shaped plate 51 drives the hot air component 53 to move synchronously. Through the above cooperation, the hot air component 53 is guaranteed to blow air to the non-woven fabric in real time, and the activity range of the hot air component 53 is expanded to avoid fixed-point blowing, so that the non-woven fabric is heated and stretched uniformly as a whole, and the non-woven fabric is prevented from being eroded by moisture during the production process, which increases the softness of the fiber and reduces the elasticity 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 inner wall of the spiral groove is restricted by the built-in block of the L-shaped plate 51, which causes the transmission rod 54 to generate a rotating force and start to rotate, and the transmission rod 54 drives the fan plate 55 to rotate. When the fan plate 55 rotates, the airflow within the heating range at the bottom of the non-woven fabric is rotated and disturbed. At the same time, the fan plate 55 The fixed ring 56 is driven to rotate, and the fixed ring 56 drives the telescopic column 57 to rotate. 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 contacts the round block on the top of the L-shaped cover plate 59, causing it to generate an upward force. The round block drives the L-shaped cover plate 59 to move upward along the outer wall of the L-shaped plate 51. The elastic force of the spring limits the round block to always be close to the outer wall of the cam 58, so that the L-shaped cover plate 59 can reciprocate up and down. Through the above cooperation, the fan plate 55 is used to quickly disturb and mix the heat flow and the moisture evaporated when the non-woven fabric is heated, so as to ensure a dry detection environment while ensuring that the non-woven fabric is evenly heated to avoid the occurrence of uniform high temperature. At the same time, the L-shaped cover plate 59 blocks the top of the hot air component 53 to prevent dirt from entering, and at the same time guides the airflow deposited under the L-shaped plate 51, thereby increasing the overall temperature of the internal space of the detection component 2 and reducing the temperature difference.

[0032] 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 32, and the staff pulls one end of the non-woven fabric to be placed on the top plane of the stretching component 7, and rotates the screw 10. When the screw 10 rotates, the spiral groove on its outer wall restricts the block inside the pressing plate 9, and the block constantly contacts the inner wall of the spiral groove of the screw 10, so that the pressing plate 9 can slide downward along the outer wall of the screw 10, and the back of the pressing plate 9 is restricted by the vertical plate 8, so that the pressing plate 9 can slide downward stably along the front of the vertical plate 8; S2: After the pressing plate 9 has stably pressed the non-woven fabrics of different thicknesses, the staff inserts the round column into the limiting hole of the rotating component 31 to limit the rotating component 31, and 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 that it is stationary; S3: 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 is first in contact with the top of the non-woven fabric, and the inclined push plate 15 is pushed away from the center of the pressing plate 9 along the arc surface at the bottom of the inclined push plate 15 and its own inclination angle. 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 inside of the circular groove of the pressing plate 9, and 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 resistance force causes the telescopic end of the elastic telescopic rod 12 to shrink upward. When the telescopic end of the elastic telescopic rod 12 shrinks to the bottom, the elastic telescopic rod 12 slides upward as a whole and resists the deformation of the spring sheet 11. At this time, the positioning rubber plate 13 fits into the inside of the circular hole at the bottom of the pressing plate 9; S4: Start the electric slide 34, which drives the transmission column 6 to slide to the left 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 stretch synchronously. The stretching distance generated by the stretching component 7 during the pulling process is converted into elastic detection data by the stretching component 7, and 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 convenience of recording by the staff.
