Since the lifting rod is perpendicular to the guide rails, the length direction of the lifting rod is perpendicular to the longitudinal direction of the cloth. Therefore, the descending of the lifting rod will press the longitudinal direction of the cloth down. When the cloth is deformed downward in the longitudinal direction, the cloth will pull the longitudinal sliding contact to move along the longitudinal direction of the cloth, which can drive the first tension rope on the upper side of the longitudinal sliding contact to pull, so that the longitudinal tension sensor can obtain the corresponding longitudinal tension value, and then detect the longitudinal tensile force and deformation of the cloth.

The lifting block descends, thereby causing the lifting rod between the two lifting blocks to descend. Since the lifting rod is perpendicular to the guide rail, the length direction of the lifting rod is perpendicular to the transverse direction of the cloth, so the descending lifting rod will press the transverse direction of the cloth down. When the cloth is deformed downward in the transverse direction, the cloth will pull the transverse sliding contact to move along the transverse direction of the cloth, which can drive the second tension rope on the upper side of the transverse sliding contact to pull, so that the transverse tension sensor can obtain the corresponding transverse tension value, and then detect the transverse tensile force and deformation of the cloth. By arranging multiple transverse tension sensors in the transverse direction of the cloth, the tensile force of each transverse area of ​​the cloth can be detected separately, thereby improving the effect of cloth detection.

Similarly, the winding roller 21 is fixed to the fixed bracket 201 on the other side. When in use, the first driving servo motor 205 drives the first driving gear 204 to rotate, and then drives the first driven gear 203 to rotate, so that the rotating rod 202 at the center of the first driven gear 203 can be driven to rotate, and then the unwinding roller 3 and the winding roller 21 at the other end of the rotating rod 202 are driven to rotate, so as to complete the unwinding and winding of the cloth.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig.10As shown, columns 9 are fixedly provided on the front and rear sides of the middle of the bottom plate 1, a horizontal plate 10 is fixedly provided on the upper end of the column 9, a rotating shaft 11 is rotatably provided through the middle of the horizontal plate 10, and a second adjusting mechanism 12 for driving the rotating shaft 11 to rotate is provided on the upper side of the horizontal plate 10. The second adjusting mechanism 12 includes a second driven gear 1203 fixedly sleeved on the upper end of the rotating shaft 11, a second adjusting servo motor 1201 is fixedly provided on the upper side of the horizontal plate 10, and a second driving gear 1202 meshing with the second driven gear 1203 is fixedly provided on the output end of the second adjusting servo motor 1201. When in use, the second driving gear 1202 is driven to rotate by the second adjusting servo motor 1201, and then the second driven gear 1203 is driven to rotate, so that the rotating shaft 11 at the inner center of the second driven gear 1203 can be driven to rotate, so as to facilitate the longitudinal and transverse tensile force detection of the fabric.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig. 9 , Fig.12As shown, a horizontally arranged guide rail 13 is fixedly arranged at the lower end of the rotating shaft 11, and a pressure detection mechanism 15 is arranged at the lower side of the guide rail 13. The pressure detection mechanism 15 includes a mounting plate 1501 arranged below the guide rail 13, and vertical electric telescopic rods 1502 are fixedly arranged at both ends of the mounting plate 1501. The output ends of the two vertical electric telescopic rods 1502 are fixedly arranged with lifting blocks 1503 located below the mounting plate 1501, and a lifting rod 16 is rotatably arranged between the two lifting blocks 1503. A first adjusting servo motor 1508 for driving the lifting rod 16 to rotate is fixedly arranged at one end of the lifting block 1503. A plurality of first pressure sensors 1505 are fixedly arranged on the lower side of the lifting rod 16, a plurality of threaded holes 1504 are opened on the upper side of the lifting rod 16, ball rods 1506 are installed on the threaded holes 1504, and a second pressure sensor 1507 is fixedly arranged on the outer surface of the ball rod 1506. The lifting rod 16 is driven to rotate 180° by the first adjustment servo motor 1508, so that the positions of the second pressure sensors 1507 and the first pressure sensors 1505 on the ball rods 1506 on both sides of the lifting rod 16 can be adjusted, so that personnel can apply a point of pressure to the fabric, detect the tensile force and deformation of the fabric, and improve the fabric quality. In order to ensure the comprehensiveness of fabric detection, when the two ends of the fabric are fixed, the second adjusting servo motor 1201 drives the second driving gear 1202 to rotate, and then drives the second driven gear 1203 to rotate, so that the rotating shaft 11 rotates. When the guide rail 13 at the lower end of the rotating shaft 11 is parallel to the longitudinal direction of the fabric (i.e. the length direction of the fabric), the second adjusting servo motor 1201 stops working. At this time, the lifting block 1503 is driven to descend through the vertical electric telescopic rod 1502, so that the lifting rod 16 between the two lifting blocks 1503 is lowered. Since the lifting rod 16 is perpendicular to the guide rail 13, the length direction of the lifting rod 16 is The lifting rod 16 is perpendicular to the longitudinal direction of the cloth, so the descent of the lifting rod 16 will press the cloth in the longitudinal direction. When the cloth is deformed downward in the longitudinal direction, the cloth will reversely press the multiple first pressure sensors 1505 on the lower side of the lifting rod 16, so that the personnel can adjust the pressure when detecting the longitudinal tensile force. The second adjusting servo motor 1201 can also drive the second driving gear 1202 to rotate, and then drive the second driven gear 1203 to rotate, so that the rotating shaft 11 rotates. When the guide rail 13 at the lower end of the rotating shaft 11 is parallel to the transverse direction of the cloth (i.e., the width direction of the cloth), the pressure applied to the width direction of the cloth can be adjusted.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.12As shown, a second driving mechanism 14 for driving the pressure detection mechanism 15 to slide is provided on the inner side of the guide rail 13, and the second driving mechanism 14 includes a second screw rod 1402 rotatably arranged on the inner side of the guide rail 13, and a second driving servo motor 1401 for driving the second screw rod 1402 to rotate is fixedly provided at one end of the guide rail 13, and a slider 1403 slidably connected to the guide rail 13 is provided on the outer thread sleeve of the second screw rod 1402, and the lower end of the slider 1403 is fixedly connected to the mounting plate 1501. When in use, the second screw rod 1402 is driven to rotate by the second driving servo motor 1401, so that the slider 1403 can slide laterally under the restriction of the guide rail 13, and then the pressure detection mechanism 15 on the lower side of the slider 1403 moves along the cloth, so as to detect the tensile force and deformation of the cloth at different positions.

[0024] like Figure 2 , Figure 3 , Figure 8As shown, the front and rear sides of the horizontal plate 10 are both vertically fixed with a suspension rod 17, the lower end of the suspension rod 17 is fixedly provided with a vertically arranged suspension plate 18, the outer side of the suspension plate 18 is horizontally fixedly provided with a transverse electric telescopic rod 19, the front and rear sides of the horizontal plate 10 are both provided with a transverse tension detection mechanism 20, the transverse tension detection mechanism 20 is fixedly provided on the output end of the transverse electric telescopic rod 19, the transverse tension detection mechanism 20 includes a movable plate 2001 fixedly provided at the output end of the transverse electric telescopic rod 19, an upper transverse plate 2010 is horizontally fixedly provided at the upper end of one side of the movable plate 2001, a lower transverse plate 2011 is horizontally fixedly provided at the lower end of one side of the movable plate 2001, and a second electric telescopic rod 2010 is vertically fixedly provided on the upper side of the upper transverse plate 2010 002, a second push bracket 2003 which slides vertically on one side of the movable plate 2001 is fixedly provided at the output end of the second electric telescopic rod 2002, a second lifting plate 2004 which is located above the lower horizontal plate 2011 is fixedly provided at the lower end of the second push bracket 2003, a plurality of second sliding bars 2009 are fixedly provided on the lower side of the second lifting plate 2004, a plurality of second sliding bars 2009 are slidably sleeved with second sliding sleeves 2007 on the upper sides of the plurality of second sliding sleeves 2007, a plurality of transverse sliding contacts 2008 are fixedly provided on the lower sides of the plurality of second sliding sleeves 2007, a plurality of transverse tension sensors 2005 are fixedly provided on the upper side of the second lifting plate 2004, and the detection ends of the plurality of transverse tension sensors 2005 are respectively fixedly connected to the plurality of second sliding sleeves 2007 which are fixedly connected to the plurality of second sliding sleeves 2007. When the second tension rope 2006 connected to the second push support 2003 is used, when it is necessary to detect the tensile force of the fabric in the transverse direction (i.e., the width direction of the fabric), the movable plate 2001 is first driven to approach the width direction of the fabric through the transverse electric telescopic rod 19, so that the fabric falls between the lower transverse plate 2011 and the plurality of transverse sliding contacts 2008 in the width direction, and then the second push support 2003 is driven to descend through the second electric telescopic rod 2002, so that the second lifting plate 2004 at the lower end of the second push support 2003 is lowered, driving the plurality of transverse sliding contacts 2008 on the lower side of the second lifting plate 2004 to press the fabric in the width direction onto the lower transverse plate 2011, and then the second adjusting servo motor 1201 drives the second driving gear 1202 to rotate, thereby driving the second The driven gear 1203 rotates to rotate the shaft 11. When the guide rail 13 at the lower end of the shaft 11 is parallel to the horizontal direction of the cloth, the second regulating servo motor 1201 stops working. At this time, the lifting block 1503 is driven to descend through the vertical electric telescopic rod 1502, thereby causing the lifting rod 16 between the two lifting blocks 1503 to descend. Since the lifting rod 16 is perpendicular to the guide rail 13, the length direction of the lifting rod 16 is perpendicular to the horizontal direction of the cloth. Therefore, the descent of the lifting rod 16 will press the cloth to descend in the horizontal direction. When the cloth is deformed downward in the horizontal direction, the edge of the cloth in the width direction will pull the horizontal sliding contact 2008 to move in the horizontal direction of the cloth, which can drive the second tension rope 2006 on the upper side of the horizontal sliding contact 2008 to pull.The lateral tension sensor 2005 can obtain the corresponding lateral tension value, and then detect the lateral tensile force and deformation of the cloth. By setting multiple lateral tension sensors 2005 in the lateral direction of the cloth, the tensile force of each lateral area of ​​the cloth can be detected separately, thereby improving the effect of cloth detection.

[0025] Embodiment 2: Based on embodiment 1, further improvement is made in that Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7As shown, a support frame 4 is provided on the upper side of the bottom plate 1, which is located between the unwinding roller 3 and the transverse plate 10, and between the winding roller 21 and the transverse plate 10. A lower bottom plate 5 is fixedly provided horizontally on the inner side of the two support frames 4. A rubber strip 6 is fixedly provided on the upper side of the lower bottom plate 5. A longitudinal tension detection mechanism 7 is provided on the upper side of the bottom plate 1, which is located between the unwinding roller 3 and the transverse plate 10, and between the winding roller 21 and the transverse plate 10. The longitudinal tension detection mechanism 7 is provided on the upper side of the support frame 4. The longitudinal tension detection mechanism 7 includes a first electric telescopic rod 702 fixedly provided vertically on the upper side of the support frame 4. The output end of the first electric telescopic rod 702 A first pushing bracket 701 located on the inner side of the support frame 4 is fixedly provided, a first lifting plate 703 slidably connected to the support frame 4 is fixedly provided on the lower side of the first pushing bracket 701, a plurality of first sliding rods 704 are fixedly provided on the lower side of the first lifting plate 703, a plurality of first sliding rods 704 are slidably sleeved with first sliding sleeves 705, a plurality of first sliding sleeves 705 are fixedly provided with longitudinal sliding contacts 706 cooperating with the rubber strip 6 on the lower sides, a plurality of longitudinal tension sensors 708 are fixedly provided on the upper side of the first lifting plate 703, and the detection ends of the plurality of longitudinal tension sensors 708 are respectively fixedly connected to the plurality of first sliding sleeves 705 fixedly provided with the first sliding contacts 706 ... When the longitudinal tensile force of the fabric (i.e., the length direction of the fabric) needs to be detected, the second adjusting servo motor 1201 first drives the second driving gear 1202 to rotate, and then drives the second driven gear 1203 to rotate, so that the rotating shaft 11 rotates. When the guide rail 13 at the lower end of the rotating shaft 11 is parallel to the longitudinal direction of the fabric (i.e., the length direction of the fabric), the second adjusting servo motor 1201 stops working. At this time, the lifting block 1503 is driven to descend through the vertical electric telescopic rod 1502, so that the lifting rod 16 between the two lifting blocks 1503 is lowered. Since the lifting rod 16 is perpendicular to the guide rail 13, the lifting rod 16 is perpendicular to the guide rail 13. The length direction of the lowering rod 16 is perpendicular to the longitudinal direction of the cloth, so the lowering of the lifting rod 16 will press the longitudinal direction of the cloth down. When the cloth is deformed downward in the longitudinal direction, the cloth will pull the longitudinal sliding contact 706 to move along the longitudinal direction of the cloth, which can drive the first tension rope 707 on the upper side of the longitudinal sliding contact 706 to be pulled, so that the longitudinal tension sensor 708 can obtain the corresponding longitudinal tension value, and then detect the longitudinal tensile force and deformation of the cloth. By arranging multiple longitudinal tension sensors 708 in the longitudinal direction of the cloth, the tensile force of each longitudinal area of ​​the cloth can be detected separately, thereby improving the effect of cloth detection.

[0026] like Figure 1 , Figure 2 , Figure 3As shown, one side of the two support frames 4 is provided with a first adjustment mechanism 8 that drives it to slide, and the first adjustment mechanism 8 includes a slide groove 802 opened on the front and rear upper sides of one end of the bottom plate 1, and the inner sides of the two slide grooves 802 are slidably provided with a slide seat 801, and a slide plate 803 located on the upper side of the bottom plate 1 is fixedly provided between the two slide seats 801, and a first screw rod 804 is rotatably provided on one side of the slide plate 803, and a hand wheel is provided at one end of the first screw rod 804, and a fixing plate 805 fixedly connected to the upper side of one end of the bottom plate 1 is provided on the middle thread sleeve of the first screw rod 804. When in use, the first screw rod is rotated The handwheel at one end of 804 can make the first screw rod 804 extend and retract in the center of the fixed plate 805, thereby driving the slide plate 803 at one end of the first screw rod 804 to slide, so that the slide seats 801 at both ends of the slide plate 803 slide on the inner sides of the slide groove 802 respectively, driving the support frame 4 on the upper side of the two slide seats 801 to slide on the bottom plate 1, so that the distance between the two support frames 4 can be adjusted, and the clamping position in the length direction of the cloth can be adjusted, that is, the length of the cloth detection can be adjusted, and different detection lengths can be used according to different cloths, thereby improving the practicability of the device detection.

[0027] It should be noted that, when using the fabric tensile force detection device, firstly, the two ends of the unwinding roller 3 are placed on the lower buckle plate 206 of the two rotating rods 202 close to each other at one end, and then the upper buckle plate 207 and the lower buckle plate 206 are fastened by bolts, so that the two ends of the unwinding roller 3 can be fixed, and similarly, the winding roller 21 is fixed to the fixed bracket 201 on the other side, so that the fabric on the unwinding roller 3 passes through the upper side of the rubber strip 6 on the left bracket frame 4 in sequence, then passes through the lower side of the lifting rod 16, and then passes through the upper side of the rubber strip 6 on the right bracket frame 4, and finally is wound onto the winding roller 21, and the first driving gear 204 is driven to rotate by the first driving servo motor 205, thereby driving the first driven gear 203. When the first driven gear 203 rotates, the rotating rod 202 at the center of the first driven gear 203 can be driven to rotate, thereby driving the unwinding roller 3 and the winding roller 21 at the other end of the rotating rod 202 to rotate, and then the first electric telescopic rod 702 on the upper side of the two support frames 4 drives the first pushing bracket 701 to descend, and pushes the first lifting plate 703 at the lower end of the first pushing bracket 701 to descend, so that the first sliding rod 704, the first sliding sleeve 70705, the longitudinal sliding contact 706, the first tension rope 707 and the longitudinal tension sensor 708 on the lower side of the first lifting plate 703 are lowered together, so that the multiple longitudinal sliding contacts 706 press the two ends of the cloth against the upper side of the rubber strip 6, so that the two ends of the cloth can be fixed, and then when the cloth needs to be adjusted longitudinally (i.e., the length of the cloth) When detecting the tensile force in the direction of the cloth (in the direction of the cloth), the second adjusting servo motor 1201 first drives the second driving gear 1202 to rotate, and then drives the second driven gear 1203 to rotate, so that the rotating shaft 11 rotates. When the guide rail 13 at the lower end of the rotating shaft 11 is parallel to the longitudinal direction of the cloth (i.e., the length direction of the cloth), the second adjusting servo motor 1201 stops working. At this time, the lifting block 1503 is driven to descend through the vertical electric telescopic rod 1502, so that the lifting rod 16 between the two lifting blocks 1503 is lowered. Since the lifting rod 16 is perpendicular to the guide rail 13, the length direction of the lifting rod 16 is perpendicular to the longitudinal direction of the cloth. Therefore, the descent of the lifting rod 16 will press the cloth to descend in the longitudinal direction. When the cloth is deformed downward in the longitudinal direction, the cloth The longitudinal sliding contact 706 will be pulled to move along the longitudinal direction of the fabric, which can drive the first tension rope 707 on the upper side of the longitudinal sliding contact 706 to pull, so that the longitudinal tension sensor 708 can obtain the corresponding longitudinal tension value, and then detect the longitudinal tensile force and deformation of the fabric. When it is necessary to detect the transverse tensile force of the fabric (i.e., the width direction of the fabric), firstly, the movable plate 2001 is driven to approach the width direction of the fabric through the transverse electric telescopic rod 19, so that the fabric falls between the lower horizontal plate 2011 and the plurality of transverse sliding contacts 2008 in the width direction, and then the second electric telescopic rod 2002 is used to drive the second pushing bracket 2003 to descend, so that the second lifting plate 2004 at the lower end of the second pushing bracket 2003 descends.The second lifting plate 2004 is driven by a plurality of transverse sliding contacts 2008 on the lower side to press the cloth against the lower transverse plate 2011 in the width direction, and then the second driving gear 1202 is driven to rotate by the second adjusting servo motor 1201, thereby driving the second driven gear 1203 to rotate, so that the rotating shaft 11 rotates. When the guide rail 13 at the lower end of the rotating shaft 11 is parallel to the cloth in the transverse direction, the second adjusting servo motor 1201 stops working, and at this time, the lifting block 1503 is driven to descend by the vertical electric telescopic rod 1502, thereby causing the lifting rod between the two lifting blocks 1503 to rotate. 16 is lowered. Since the lifting rod 16 is perpendicular to the guide rail 13, the length direction of the lifting rod 16 is perpendicular to the horizontal direction of the fabric. Therefore, the lifting rod 16 will press the fabric downward in the horizontal direction. When the fabric is deformed downward in the horizontal direction, the edge of the fabric in the width direction will pull the horizontal sliding contact 2008 to move along the horizontal direction of the fabric, which can drive the second tension rope 2006 on the upper side of the horizontal sliding contact 2008 to pull, so that the horizontal tension sensor 2005 can obtain the corresponding horizontal tension value, and then detect the horizontal tensile force and deformation of the fabric.
