Description

Technical Field

[0001] This invention relates to the field of high-elasticity and abrasion-resistant cotton elastic fabric technology, and more specifically, to an elasticity testing device and a testing method for high-elasticity and abrasion-resistant cotton elastic fabric. Background Technology

[0002] High-elasticity and abrasion-resistant cotton elastic fabric refers to cotton elastic fabric with high elasticity and good abrasion resistance. This fabric combines the natural comfort of cotton with the elasticity advantage of elastic fibers and has a wide range of applications in clothing, home furnishings and other fields. However, accurate testing of its elasticity performance is crucial to ensuring product quality. This invention is a device and testing method designed for testing the elasticity of high-elasticity and abrasion-resistant cotton elastic fabric.

[0003] According to patent document CN117147299A, a device for testing the tensile strength of embroidered fabric includes a base plate, a clamping mechanism, and a stretching mechanism. In this invention, the tensile force applied to the embroidered fabric by the side plates continuously increases, i.e., the tensile force is continuously increased in the left-right direction of the embroidered fabric during tensile testing. Then, a release assembly fixes the distance between the suspension plate and the corresponding trapezoidal block. Simultaneously, the clamping plate on the longer release column is rotated to move out of its corresponding slot, and energy is stored by compressing the corresponding spring. Then, the shorter release column is rotated, causing the spring compression to generate elastic force that acts on the trapezoidal block, ultimately causing the left and right side plates to quickly move away from each other. This applies an instantaneous tensile force to both ends of the embroidered fabric, performing an instantaneous tensile test in the left-right direction, ensuring comprehensiveness in the tensile testing of the fabric.

[0004] Traditional fabric testing devices typically assess elasticity by stretching a portion of the fabric in a single direction, utilizing the tension generated by the expanded portion. However, this method has limitations, failing to comprehensively and accurately reflect the true elasticity characteristics of high-elasticity, abrasion-resistant cotton fabric. Since the test only targets a small area of ​​the fabric, it fails to fully consider the uniform distribution and coordinated deformation of the fabric as a whole under stress, potentially leading to significant discrepancies between the test results and the actual elasticity performance during use. Furthermore, localized testing cannot simulate the multi-directional and complex stress states experienced by the fabric during actual wear or use, further limiting the accuracy and applicability of its assessment. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides an elasticity testing device and method for high-elasticity and abrasion-resistant cotton elastic fabric.

The bottoms of the two lower pressure blocks 2228 are oblique cut surfaces opposite to the rear sides of the two abutments 214, and the bottoms of the two lower pressure blocks 2228 are in contact with the rear sides of the two abutments 214. In the process of testing the elasticity performance of high-elasticity and wear-resistant cotton elastic fabric, the fabric roll to be tested must first be properly installed on the outer wall surface of the front take-up roller 18 of the equipment, and one end of the fabric is manually pulled so that it passes through the top position of the push roller 2115 and the bottom area of ​​the outer wall of the pull roller 2227 in sequence, and is finally fixed on the outer wall of the rear take-up roller 18. When the elasticity testing program is officially started, the power switch of the motor 110 must first be turned on. After the motor 110 starts running, its output end will drive the gear 111 connected to it to rotate. Since the outer wall of the gear 111 is meshed with the second gear 112, the rotation of the gear 111 will drive the rear columnar rotating rod 17 to rotate synchronously. The rotation of the rear columnar rotating rod 17 causes the rear take-up roller 18 to rotate, thereby performing a take-up operation on the fabric; on the other hand, in this process, the power transmission of the transmission disc 113 and the track 114 is also used to further drive the second transmission disc 115 to rotate. The rotation of the second transmission disc 115 will drive the transmission rod 2218 to rotate inside the transmission rod sleeve 2217. The rotation of the transmission rod 2218 will further cause the inner transmission turntable 2219 to rotate. The inner transmission turntable 2219 will drive the second inner transmission turntable 22111 to rotate synchronously through the power transmission of the second track 22110. The rotation of the second inner transmission turntable 22111 will eventually drive the inner transmission rod 22112 to rotate. The abutment transmission turntable 22113 at both ends of the inner transmission rod 22112 will rotate together, so that the abutment 22114 fixed on it will perform continuous circular motion. During the rotation of the abutment block 22114, it periodically applies a squeezing force to the elliptical sleeve block 2221, causing the elliptical sleeve block 2221 to drive the second columnar upright 2222 to slide up and down inside the columnar upright guide block 2216. During this movement, the second spring 2223 continuously undergoes elastic deformation of compression and stretching. The up and down sliding of the second columnar upright 2222 further drives the third push-pull upright slider 2224 to slide up and down inside the guide plate 2215 in the guide frame. Then, the third push-pull upright 2225 pushes the concave pull-down roller connecting plate 2226 to move up and down, ultimately enabling the pull-down roller 2227 to achieve up and down reciprocating motion. Meanwhile, the front take-up and release roller 18 is also continuously rotating under the indirect drive of the motor 110. When the high-elasticity and wear-resistant cotton elastic fabric passes the top position of the push roller 2115 and the bottom area of ​​the outer wall of the pull roller 2227, the up-and-down reciprocating motion of the pull roller 2227 will apply periodically changing tension to the fabric. Under the action of tension, the fabric will undergo corresponding elastic deformation. During this process, the downward movement of the concave pull roller connecting plate 2226 will synchronously drive the two pressing blocks 2228 to move downward, thereby pressing the two abutment plates 214 and pushing the L-shaped side moving plate 213 forward. The forward movement of the L-shaped side moving plate 213 further drives the two triangular bottom abutment plates 2117 to move forward, thereby pushing the hub 2118 to slide on the top surface of the triangular bottom abutment plate 2117. The movement of the hub 2118 is transmitted to the columnar push-pull rod 2121 through the inverted concave block 2120, which drives the lifting plate 2112 to slide at the bottom of the inner wall of the front side of the guide plate 2111. At this time, the spring 2122 is compressed or stretched accordingly. The movement of the lifting plate 2112 finally pushes the push roller connecting plate 2114 and the push roller 2115 to move upward through the two lifting plates 2113. Therefore, when the pull roller 2227 moves downward, the push roller 2115 pushes upward simultaneously, which further increases the tension on the high-elasticity and wear-resistant cotton elastic fabric, and the degree of deformation of the fabric becomes more significant. In this state, the scanning slant plate 219 connected to the equipment will monitor and capture the specific value of the tension on the fabric in real time, and transmit these data to the display screen of the control system in real time. By observing the dynamic change value of the tension on the display screen, the testing personnel can intuitively and accurately evaluate the elastic performance of the high-elasticity and wear-resistant cotton elastic fabric under different tension conditions.

[0022] In addition, the present invention also relates to a testing method for an elasticity testing device of high-elasticity and abrasion-resistant cotton elastic fabric, comprising the following steps: Step 1: Place the fabric roll on the outer wall of the front take-up roller 18, and pull one end of the fabric through the top of the push roller 2115 and the bottom of the outer wall of the pull roller 2227 to the outer wall of the rear take-up roller 18. Step 2: Start motor 110, and the output of motor 110 will drive gear 111 to rotate; Step 3: Gear 111 drives the second gear 112, which meshes with it, to rotate, causing the rear cylindrical rotating rod 17 to rotate; Step 4: The rear columnar rotating rod 17 rotates to cause the rear take-up roller 18 to take up the fabric, and at the same time, it drives the second transmission disk 115 to rotate through the transmission disk 113 and the track 114. Step 5: The second transmission disc 115 drives the transmission rod 2218 to rotate, and the inner transmission disc 2219 rotates accordingly; Step 6: The inner transmission turntable 2219 drives the second inner transmission turntable 22111 to rotate through the second track 22110, and the abutment block 22114 performs circular motion to compress the elliptical sleeve block 2221; Step 7: The elliptical sleeve 2221 drives the second columnar upright 2222 to slide up and down, causing the pull roller 2227 to move up and down, generating different tensions on the fabric; Step 8: The concave pull-down roller connecting plate 2226 drives the lower pressure block 2228 to push the top push roller 2115 to the top, increasing the fabric tension; Step 9: The scanning slant 219 captures the tension of the fabric in real time and transmits the data to the control system display screen; Step 10: The testing personnel observe the tension change values ​​on the display screen to understand the elasticity performance of the high-elasticity and wear-resistant cotton elastic fabric.

[0023] Working principle of this invention: When it is necessary to test the elasticity of high-elasticity and wear-resistant cotton elastic fabric, the fabric roll is first placed on the outer wall of the front take-up roller 18, and one end is pulled through the top of the push roller 2115 and the bottom of the pull roller 2227 to the outer wall of the rear take-up roller 18. When it is necessary to test the elasticity, the motor 110 is started first. After the motor 110 is started, its output end drives the gear 111 to rotate. Since the gear 111 meshes with the outer wall of the second gear 112, it drives the rear columnar rotating rod 17 to rotate. The rotation of the rear columnar rotating rod 17 causes the rear take-up roller 18 to rotate and roll up the fabric. During this process, the second transmission disc 115 is driven to rotate through the transmission disc 113 and the track 114. The second transmission disc 115 then drives the transmission disc 115 to rotate. The rotating rod 2218 rotates within the transmission rod sleeve 2217. The rotation of the transmission rod 2218 causes the inner transmission turntable 2219 to rotate. The inner transmission turntable 2219, via the second track 22110, drives the second inner transmission turntable 22111 to rotate. The second inner transmission turntable 22111 drives the inner transmission rod 22112 to rotate. The abutment blocks at both ends of the inner transmission rod 22112 rotate accordingly, and the abutment blocks 22114 also perform circular motion. During the rotation of the abutment blocks 22114, they periodically compress the elliptical sleeve 2221, causing the elliptical sleeve 2221 to drive the second columnar upright 2222 to slide up and down within the columnar upright guide block 2216. The second spring 2223 is compressed and stretched. The up and down sliding of the second columnar upright 2222 drives the third... The push-pull rod slider 2224 slides up and down inside the guide plate 2215 within the guide frame, thereby driving the concave pull-down roller connecting plate 2226 to move up and down through the third push-pull rod 2225, causing the pull-down roller 2227 to move up and down. At the same time, the front take-up and release roller 18 rotates indirectly driven by the motor 110. When the high-elastic wear-resistant cotton elastic fabric passes the top of the push roller 2115 and the bottom of the outer wall of the pull-down roller 2227, the up and down movement of the pull-down roller 2227 will generate different tensions on the fabric. The fabric will deform under the action of tension. When the fabric deforms, at the same time, the concave pull-down roller connecting plate 2226 moves downward, which will drive the two lower pressure blocks 2228 to move downward, pressing the two abutment plates 214 and pushing the L-shaped side moving plate 213 forward. The side-moving plate 213 moves forward, which in turn drives the two triangular base plates 2117 to move forward. This, in turn, pushes the hub 2118 to slide on the top of the triangular base plates 2117. The hub 2118 drives the inverted concave block 2120 to move. The inverted concave block 2120 drives the lifting plate 2112 to slide on the bottom of the inner wall of the front side of the guide plate 2111 via the columnar push-pull upright 2121. The spring 2122 is compressed or stretched, and through the two lifting uprights 2113, it pushes the top push roller connecting plate 2114 and the top push roller 2115 to move upward. This achieves the effect that when the pull roller 2227 moves downward, the top push roller 2115 pushes upward. During the process of the top push roller 2115 pushing upward, the tension on the high-elastic wear-resistant cotton elastic fabric will further increase.The fabric deformation becomes more pronounced. At this point, the scanning slant 219 connected to the equipment captures the tension on the fabric in real time and transmits the data to the control system's display screen. By observing the tension changes on the screen, the testing personnel can intuitively understand the elasticity performance of the high-elasticity, abrasion-resistant cotton fabric under different tension conditions.
