Description

Technical Field

[0001] This invention relates to the field of yarn quality testing technology, and in particular to a device for testing the tensile properties of textile yarns. Background Technology

[0002] Tensile properties of textile yarns are a crucial indicator of yarn quality, directly impacting the smooth progress of subsequent weaving processes and the final mechanical properties and durability of textiles. Therefore, accurate and efficient tensile property testing is essential in yarn production and quality control, forming a fundamental and critical part of the new materials testing field. Currently, most widely used yarn tensile property testing equipment in the industry clamps both ends of the yarn using a clamping mechanism, applying gradually increasing tension until the yarn breaks, thereby recording key data such as breaking strength and elongation at break. However, the yarn clamping process typically relies on manual operation, requiring the yarn to be manually pulled from the package, passed through a yarn guide, and then fixed in two clamps. This process is not only time-consuming and labor-intensive, but also prone to accidental stretching or damage to the yarn during manual operation, introducing testing errors and affecting the accuracy and repeatability of the test results. Furthermore, most existing equipment is designed for a single station, requiring the completion of one clamping, testing, and yarn breakage removal process before the next test can proceed, resulting in low testing efficiency and failing to meet the demands of modern production for large-scale, rapid testing. Furthermore, existing equipment has poor adaptability when testing yarns of different specifications or lengths, often requiring manual adjustment of the clamping distance or replacement of the clamps, which is cumbersome and lacks flexibility. Therefore, this invention provides a textile yarn tensile property testing device. Summary of the Invention

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Example: Reference Figures 1-9A textile yarn tensile property testing device includes a base plate 101, on which two shifting frames 108 are symmetrically arranged. The two shifting frames 108 are fixedly connected and rotatably mounted on the base plate 101. The center lines of the rotatable connection between the two shifting frames 108 and the base plate 101 are on the same straight line. A shifting motor 109 is fixedly mounted on the base plate 101. The two shifting frames 108 are symmetrically arranged with respect to the axis of the shifting motor 109. The output shaft of the shifting motor 109 is fixedly connected to the rotatable connection between the shifting frames 108 and the base plate 101. When the shifting motor 109 is started, the two shifting frames 108 rotate synchronously with respect to the axis of the shifting motor 109, thereby realizing the switching of the positions of the two shifting frames 108.

[0026] The transposition frame 108 is symmetrically equipped with C-shaped strips 126 and U-shaped slide plates 119 are symmetrically slidably mounted on it. The C-shaped strips 126 are fixedly mounted on the corresponding U-shaped slide plates 119. A double-ended threaded screw 120 is provided between the two U-shaped slide plates 119 on the same transposition frame 108. The double-ended threaded screw 120 is rotatably mounted on the corresponding transposition frame 108. The threads on both sides of the double-ended threaded screw 120 form a helical pair with the corresponding U-shaped slide plate 119. An adjustable pitch motor 121 is fixedly mounted on the transposition frame 108. The output shaft of the adjustable pitch motor 121 is fixedly connected to the double-ended threaded screw 120. When the adjustable pitch motor 121 is started, it drives the double-ended threaded screw 120 to rotate. Under the action of the double-ended threaded screw 120, the two U-shaped slide plates 119 on the same transposition frame 108 move towards each other or away from each other.

[0027] C-shaped strip 126 is rotatably mounted on the side of each C-shaped strip 126. Adjustment slides 128 are symmetrically slidably mounted on both C-shaped strip 126 and C-shaped strip 127. Adjustment strips 125 are fixedly installed at the ends of the adjustment slides 128. The adjustment strips 125 are located at the ends of the adjustment slides 128 closest to the axis of the C-shaped strip 126. The adjustment strips 125 are used to position and fix the textile yarn. An adjustment unit is provided between the two opposing adjustment slides 128.

[0028] Each adjustment unit includes a strip-shaped rotating plate 133, a strip-shaped groove plate 134, and a strip-shaped rotating plate 143. Supporting short shafts 136 are fixedly installed on both C-shaped strip plates 126 and 127. Both strip-shaped rotating plates 133 and 143 in the same adjustment unit are rotatably mounted on the supporting short shafts 136. Torsion springs are provided between each strip-shaped rotating plate 133 and its corresponding supporting short shaft 136. One end of the torsion spring is fixedly connected to the supporting short shaft 136, and the other end is fixedly connected to either the corresponding strip-shaped rotating plate 133 or 143. Strip-shaped grooves are provided on both strip-shaped rotating plates 133 and 143. Adjustment short rods 132 are fixedly installed on each adjustment slide plate 128, and these rods are slidably connected to their respective strip-shaped grooves.

[0029] The strip-shaped groove plate 134 is slidably installed on the corresponding C-shaped strip plate 126 and C-shaped strip plate 127 respectively. The strip-shaped groove plate 134 is symmetrically fixedly provided with strip-shaped sliding plates 139. The strip-shaped sliding plates 139 are slidably installed on the corresponding C-shaped strip plate 126 or C-shaped strip plate 127 respectively. The strip-shaped rotating plate 133 and the strip-shaped rotating plate 143 are also fixedly provided with linkage rods 135. The strip-shaped groove plate 134 and the corresponding two linkage rods 135 are movably connected.

[0030] In the initial position, the torsion springs between the first strip rotating plate 133 and the second strip rotating plate 143 and the supporting short shaft 136 are not compressed. At this time, the included angle between the first strip rotating plate 133 and the second strip rotating plate 143 corresponding to the supporting short shaft 136 is the maximum angle. Under the action of the adjusting short rod 132, the two adjusting slide plates 128 corresponding to the same supporting short shaft 136 are located at the farthest position, that is, the two adjusting strip plates 125 corresponding to the same supporting short shaft 136 are located at the farthest position. At this time, the strip groove plate 134 is located at the farthest position from the axis of the C-shaped strip plate 126 under the action of the linkage short rod 135.

[0031] The drive bar-shaped rotating plate 133 rotates towards the axis of the C-shaped plate 126. Under the action of the adjusting short rod 132, the adjusting slide plate 128 and adjusting plate 125 corresponding to the bar-shaped rotating plate 133 move synchronously towards the axis of the C-shaped plate 126. Under the action of the linkage short rod 135, the bar-shaped groove plate 134 moves towards the axis of the C-shaped plate 126. The linkage short rod 135 on the bar-shaped rotating plate 143 moves synchronously, thereby causing the corresponding bar-shaped rotating plate 143 to also move towards the axis of the C-shaped plate 126. The torsion springs between the bar-shaped rotating plate 133 and the bar-shaped rotating plate 143 and the supporting short shaft 136 are compressed. That is, when the bar-shaped rotating plate 133 rotates, the corresponding bar-shaped rotating plate 143 rotates synchronously, thereby causing the two adjusting plates 125 corresponding to the same bar-shaped rotating plate 133 to move synchronously towards the axis of the C-shaped plate 126.

[0032] A sector gear 137 is also provided between the two opposing adjustment slide plates 128. The sector gear 137 is fixedly installed on the corresponding strip plate 133. The axis of the sector gear 137 and the axis of the corresponding support short shaft 136 are on the same straight line. A linkage unit is provided between the two adjustment units corresponding to the same C-shaped strip plate 126. The linkage unit includes a linkage slide plate 130 movably installed on the C-shaped strip plate 2 127. A support spring 131 is provided between the linkage slide plate 130 and the C-shaped strip plate 2 127. A limit block 2 141 is also fixedly provided on the C-shaped strip plate 2 127. A limit block 140 is also fixedly provided on the C-shaped strip plate 126. The limit block 140 and the limit block 2 141 are used to limit the maximum angle of rotation of the C-shaped strip plate 2 127 relative to the C-shaped strip plate 126.

[0033] A sector rack 129 is fixedly installed on the side of the linkage slide plate 130. The axes of the sector rack 129, C-shaped strip 126, and C-shaped strip 2 127 are on the same straight line. Adjustment gears 122 are rotatably installed on the U-shaped slide plate 119. The adjustment gears 122 and the corresponding sector racks 129 mesh to form a gear pair. A splined long shaft 123 is provided between the two adjustment gears 122 on the same shift frame 108. The adjustment gears 122 and the splined long shaft 123 form a spline sliding fit. Adjustment motors 124 are also fixedly installed on the shift frame 108. The output shaft of the adjustment motor 124 is fixedly connected to the splined long shaft 123. When the adjustment motor 124 is started to drive the splined long shaft 123 to rotate, the corresponding two adjustment gears 122 will rotate synchronously. When the U-shaped slide plate 119 slides relative to the shift frame 108, the adjustment gear 122 slides relative to the corresponding splined long shaft 123.

[0034] The linkage slide plate 130 is provided with an arc-shaped rack 138 and an arc-shaped rack 142. The arc-shaped rack 138 and the arc-shaped rack 142 are used to drive the corresponding sector gears 137 to move. The arc-shaped rack 138 is fixedly installed at the end of the sector rack 129, and the arc-shaped rack 142 is fixedly installed on the side of the linkage slide plate 130. The arc-shaped rack 138 and the sector gears 137 corresponding to the C-shaped plate 127 mesh to form a gear rack pair. When the C-shaped plate 127 rotates 90 degrees relative to the C-shaped plate 126, the arc-shaped rack 142 and the sector gears 137 corresponding to the C-shaped plate 126 mesh to form a gear rack pair.

[0035] In the initial position, the support spring 131 is not compressed, and the openings of the C-shaped strip 126 and the C-shaped strip 2 127 on the same U-shaped slide plate 119 are facing the same position. At this time, the adjusting strips 125 on the C-shaped strip 126 and the C-shaped strip 2 127 are both in a horizontal state, and the arc-shaped rack 2 142 is not in contact with the corresponding sector gear 137, and the limiting block 2 141 is not in contact with the corresponding limiting block 140.

[0036] The starting adjustment motor 124 drives the adjustment gear 122 to rotate, causing the sector rack 129 to rotate relative to the first C-shaped plate 126. Under the action of the support spring 131, the linkage slide plate 130 and the second C-shaped plate 127 rotate synchronously. That is, at this time, the sector rack 129, the linkage slide plate 130, and the second C-shaped plate 127 rotate as a whole relative to the first C-shaped plate 126, ultimately causing the second C-shaped plate 127 to rotate 90 degrees relative to the first C-shaped plate 126. When the adjusting strip 125 on plate 2 127 is in a vertical state, the limiting block 2 141 on C-shaped strip 2 127 moves to contact the limiting block 140 on C-shaped strip 1 126. Under the action of limiting block 140, limiting block 2 141 cannot continue to move. That is, at this time, C-shaped strip 2 127 cannot continue to rotate relative to C-shaped strip 1 126. At this time, arc-shaped rack 2 142 contacts the sector gear 137 corresponding to C-shaped strip 1 126, and the two mesh to form a gear rack pair.

[0037] As the adjusting gear 122 continues to rotate, the sector rack 129 rotates relative to the C-shaped plate 127, and the linkage slide plate 130 moves relative to the C-shaped plate 127. The support spring 131 is compressed, and the arc rack 138 and arc rack 142 corresponding to the linkage slide plate 130 move synchronously, thereby causing the two corresponding sector gears 137 to rotate synchronously, which in turn causes the two corresponding strip plates 133 to rotate synchronously. Under the action of the adjusting unit, the four adjusting plates 125 on the same U-shaped slide plate 119 move synchronously towards the axis of the C-shaped plate 126.

[0038] An auxiliary unit is also provided on the base plate 101. The auxiliary unit includes an auxiliary slide 103 and an unwinding turret 110. Traction strips 113 are symmetrically slidably mounted on the auxiliary slide 103. The traction strips 113 are used to pull the textile yarn on the unwinding turret 110. The auxiliary unit also includes a slide 102 slidably mounted on the base plate 101. A clearance screw 105 is rotatably mounted on the base plate 101. The slide 102 and the clearance screw 105 form a helical pair. A clearance motor 104 is fixedly mounted on the base plate 101. The output shaft of the clearance motor 104 is fixedly connected to the clearance screw 105. The unwinding turret 110 is rotatably mounted on the slide 102. An unwinding motor 111 is fixedly mounted on the slide 102. The output shaft of the unwinding motor 111 is fixedly connected to the unwinding turret 110. A nut 112 is also movably mounted on the unwinding turret 110. The unwinding turret 110 and the nut 112 are threadedly connected.

[0039] The start of the yielding motor 104 drives the yielding screw 105 to rotate, which causes the slide 102 to move along the axis of the yielding screw 105. The axis of the yielding screw 105 is parallel to that of the double-ended threaded screw 120. The nut 112 can fix the spool with the textile yarn wound on the unwinding turntable 110. The start of the unwinding motor 111 drives the unwinding turntable 110 to rotate and unwind the textile yarn.

[0040] A limit ring 116 is also fixedly installed on the slide 102. The limit ring 116 is used to limit the position of the unwound textile yarn on the unwinding turntable 110. Multiple cameras 144 are evenly fixedly installed on the transposition frame 108. The cameras 144 are used to monitor the changes in the textile yarn when it is stretched.

[0041] The auxiliary slide 103 is also slidably mounted on the base plate 101. A traction screw 107 is rotatably mounted on the base plate 101. A clearance screw 105 and the traction screw 107 form a helical pair. The axes of the traction screw 107 and the clearance screw 105 are parallel. A traction motor 106 is also fixedly mounted on the base plate 101. The output shaft of the traction motor 106 is fixedly connected to the traction screw 107. A double-ended threaded screw 114 is provided between the two traction plates 113. The double-ended threaded screw 114 is rotatably mounted on the auxiliary slide 103. On the auxiliary slide 103, the threads at both ends of the double-ended threaded screw 114 form a helical pair with the corresponding traction bar 113. A clamping motor 115 is fixedly installed at the upper end of the auxiliary slide 103. The output shaft of the clamping motor 115 is fixedly connected to the double-ended threaded screw 114. A thermal cutting blade 117 is also movably arranged on the side of the auxiliary slide 103. A dividing motor 118 is fixedly installed on the side of the auxiliary slide 103. The end of the thermal cutting blade 117 is fixedly installed on the output shaft of the dividing motor 118.

[0042] Starting the clamping motor 115 drives the double-ended threaded screw 114 to rotate, which causes the two traction plates 113 to move closer to each other or further apart. Starting the traction motor 106 drives the traction screw 107 to rotate, which causes the auxiliary slide 103 to move along the axis of the traction screw 107. Starting the dividing motor 118 drives the thermal cutting blade 117 to rotate.

[0043] Working principle: Based on the length of the textile yarn to be tested, the pitch adjustment motor 121 is started to adjust the distance between the two U-shaped slide plates 119. Then, the position shifting motor 109 is started to make the adjustment plates 125 all horizontal. At the same time, the traction motor 106 is started to move the auxiliary slide 103 to the position closest to the slide base 102. The winding spool with the textile yarn is fixed on the unwinding turntable 110. Then, the end of the textile yarn is manually pulled through the limiting ring 116 to the position between the two traction plates 113. Finally, the clamping motor 115 is started to fix the end of the textile yarn with the two traction plates 113.

[0044] Then, the yielding motor 104 and traction motor 106 are started to drive the slide block 102 and auxiliary slide 103 to move synchronously, so that the traction strip 113 moves to the side of the U-shaped slide plate 119 closest to the slide block 102. Then the slide block 102 stops moving, and the auxiliary slide 103 continues to move. Under the action of the unwinding motor 111, the textile yarn is unwound. Under the traction of the traction strip 113, the textile yarn passes through the area between the adjusting strips 125 on the two U-shaped slide plates 119 and moves to the outside of the U-shaped slide plate 119 closest to the slide block 102. At this time, the textile yarn between the two U-shaped slide plates 119 forms a detection section. Then, the adjusting motor 124 is started to drive the two adjusting gears 122 to rotate synchronously. Under the action of the sector rack 129, the C-shaped strips 122 are first moved to the side of the U-shaped slide plate 119 closest to the slide block 102. All 127 rotate 90 degrees relative to the C-shaped plate 126, so that the adjusting plates 125 on the C-shaped plate 127 are all in a vertical state. The adjusting gear 122 continues to rotate. Under the action of the adjusting unit, the adjusting plates 125 move towards the axis of the C-shaped plate 126. Under the action of the four adjusting plates 125 on the same U-shaped slide plate 119, the textile yarn first moves to the axis position of the C-shaped plate 126. The surface of the adjusting plate 125 closest to the axis of the C-shaped plate 126 is the friction surface. Then, under the action of the four adjusting plates 125, it is fixed. Under the action of the adjusting plates 125 on the two U-shaped slide plates 119, the two ends of the textile yarn are fixed, and the textile yarn and the axis of the C-shaped plate 126 are on the same straight line.

[0045] After the adjusting plate 125 has fixed both ends of the textile yarn, the clamping motor 115 is started to move the two traction plates 113 to the farthest position. Then the traction motor 106 is started to move the auxiliary slide 103 back to the position closest to the slide 102. The two traction plates 113 return from the upper and lower sides of the U-shaped slide plate 119 to the position closest to the slide 102. After the traction plates 113 return to the position closest to the slide 102, the clamping motor 115 is started again to make the traction plates 113 clamp and fix the textile yarn again. At this time, the dividing motor 118 is started to drive the thermal cutting blade 117 to rotate. Under the action of the thermal cutting blade 117, the textile yarn is divided. Then the yielding motor 104 and the traction motor 106 are started to make the slide 102 and the auxiliary slide 103 return to the initial position, that is, to make way for the rotation of the transposition frame 108.

[0046] After the slide 102 and auxiliary slide 103 return to their initial positions, the shift motor 109 is started to drive the two shift frames 108 to switch positions. The above positions are repeated to realize the reinstallation of the textile yarn on the shift frame 108. At this time, the two U-shaped slides 119 on the shift frame 108 that hold and fix the textile yarn move away from each other, thus realizing the tensile test of the textile yarn. The changes of the textile yarn are detected in real time by the camera 144 on the shift frame 108.

[0047] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
