DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example 1: Reference Figures 1-8 A knitted denim fabric wear resistance detection device includes: a frame 1, a tension frame 2, a base 3, a groove 4, a pressure shaft 5 and a spring 6. Two tension frames 2 are slidably connected to the frame 1, and each tension frame 2 is slidably connected to a base 3. A groove 4 is opened on the top of the base 3. The pressure shaft 5 is rotatably connected to the tension frame 2. The convex strip 24 on the side of the pressure shaft 5 contacts and cooperates with the groove 4. The bottom of the base 3 is connected to the tension frame 2 through a spring 6.

[0029] The principles of the above scheme are:

[0030] Place the two ends of the fabric on the top of a base 3 respectively, then rotate the pressure shaft 5, and make the convex strip 24 of the pressure shaft 5 contact and cooperate with the groove 4. The spring 6 cooperates with the base 3 to apply elastic force to clamp the fabric. Further, based on the material of the fabric and the required test tension, increase the distance between the two tension frames 2 on the frame 1, and perform a wear resistance test.

[0031] The beneficial effects of the above scheme are:

[0032] The device greatly reduces the difficulty of clamping and positioning the fabric end by providing the base 3, the groove 4, the pressure shaft 5 and the ridge 24, increases the stability of the fabric during testing, and improves the accuracy of fabric testing.

[0033] Example 2: Reference Figures 1-8 The frame 1 is connected to a screw lifting mechanism 7 , and the output end of the screw lifting mechanism 7 is connected to a grinding piece 8 .

[0034] The principles and beneficial effects of the above scheme are:

[0035] After the fabric is clamped, the screw lifting mechanism 7 is started, and its output end drives the polishing piece 8 to move up and down to adjust the pressure on the fabric. Then the screw lifting mechanism 7 is closed and the polishing piece 8 is started to start the wear resistance test of the fabric, which improves the efficiency of fabric testing and improves the accuracy of the pressure applied to the top of the fabric during the wear resistance test.

[0036] Example 3: Reference Figures 1-8 The pressure shaft 5 is connected to a gear 9 on the side wall of the end away from the tension frame 2. The gear 9 is meshed with the top of the gear 2 10. The gear 2 10 is rotatably connected to the tension frame 2. The bottom of the gear 2 10 is connected with a sector tooth 11. The sector tooth 11 is meshed with the rack 12 on the frame 1. The tension frame 2 and the gear 2 10 are connected by a torsion spring 13, and the torsion spring 13 is in a torsional state of storing elastic potential energy.

[0037] The principles and beneficial effects of the above scheme are:

[0038] When the two tension frames 2 move away from each other, the sector teeth 11 are meshed with the rack 12, the rack 12 drives the gear 2 10 to rotate, the gear 2 10 drives the gear 9 meshed with it to rotate, and then drives the pressure shaft 5 to rotate. During the rotation of the pressure shaft 5, the convex strips 24 connected to the side wall can contact and cooperate with the groove 4, thereby completing the automatic clamping of the fabric end, avoiding manual clamping operations and reducing workload;

[0039] When the device automatically clamps the fabric, manual operation is avoided, thereby preventing the operator from being hurt during the clamping process, thereby improving the safety of the device when in use;

[0040] The accuracy of the device in clamping the fabric is further improved, preventing the fabric from moving during testing and obtaining accurate measurement results.

[0041] Before the fabric is clamped, the torsion spring 13 is in a state of torsion storage of elastic potential energy. When the sector teeth 11 are meshed with the rack 12, the torsion spring 13 releases the elastic stored energy. After the sector teeth 11 and the rack 12 are no longer meshed with each other, that is, after the end of the fabric is clamped, the sector teeth 11 can be kept facing the end of the rack 12 under the action of the torsion spring 13, preparing for the reverse meshing connection between the sector teeth 11 and the rack 12.

[0042] When the distance between the two tension frames 2 increases to a certain extent, the engagement connection between the sector teeth 11 and the rack 12 is completed. Since the torsion spring 13 is provided to limit the position of the sector teeth 11, when the ridge 24 can contact and cooperate with the groove 4, there is relative friction between the side of the sector teeth 11 and the top of the rack 12, and the sector teeth 11 will not be rotated again, so the pressure shaft 5 will not be caused to rotate significantly, so the ridge 24 will not be separated from the groove 4. At the same time, the secondary engagement of the sector teeth 11 and the rack 12 can be guaranteed, thereby improving the rationality of the cyclic operation of the device.

[0043] After the end of the fabric is clamped, the torsion spring 13 can be provided to assist in limiting the rotation of the pressure shaft 5, thereby preventing the fabric from falling off during testing.

[0044] When the sector teeth 11 and the rack 12 are reversely meshed and connected, that is, when the two tension frames 2 approach each other, the torsion spring 13 is twisted and stored again, and then the pressure shaft 5 drives the convex strip 24 to reset, thereby releasing the end of the fabric that has completed the test, further improving the efficiency of the device during testing.

[0045] Example 4: Reference Figures 1-8 In the screw lifting mechanism 7, the output end of the lifting motor is connected to the bottom of the lifting screw 14, the lifting screw 14 is threadedly connected to the lifting plate 15, the lifting plate 15 is slidingly connected to the frame 1, and the grinding piece 8 is connected to the lifting plate 15.

[0046] The principles and beneficial effects of the above scheme are:

[0047] After the fabric is fixed, the lifting motor is started, and the output end of the lifting motor rotates forward to drive the lifting screw 14 to rotate forward. Under the sliding cooperation of the frame 1, the lifting plate 15 moves upward, and the polishing piece 8 reduces the pressure on the top surface of the fabric;

[0048] The reverse rotation of the output end of the lifting motor drives the lifting screw 14 to reverse, and the lifting plate 15 moves downward under the sliding cooperation of the frame 1. The polishing part 8 increases the pressure on the top surface of the fabric, reducing the difficulty of pressure adjustment during testing and improving the accuracy of pressure adjustment.

[0049] Example 5: Reference Figures 1-8 The grinding part 8 includes: a motor 16, a connecting pipe 17 and a grinding roller 18. The lifting plate 15 is connected to the motor 16. The output shaft of the motor 16 is connected to the grinding roller 18 through the connecting pipe 17. The grinding roller 18 is arranged between the two pressure shafts 5.

[0050] The principles and beneficial effects of the above scheme are:

[0051] When conducting a wear resistance test, the rotation speed of the output shaft of the motor 16 can be adjusted based on the different fabrics and test parameters, and then the rotation speed of the connecting tube 17 and the grinding roller 18 can be adjusted to facilitate testing of different items on the fabric, thereby improving the convenience and practicality of the device during use.

[0052] Example 6: Reference Figures 1-8 The bottom of the spring 6 is connected to the top of the supporting plate 19, the supporting plate 19 is slidably connected to the tension frame 2, a longitudinal hole 20 is opened in the middle of the supporting plate 19, the longitudinal hole 20 is slidably connected to the screw block 21, and the screw block 21 is threadedly connected to a threaded portion of the double screw 22.

[0053] The ends of the twin screws 22 are connected to the output ends of the second motor 23 on the frame 1 .

[0054] The principles and beneficial effects of the above scheme are:

[0055] After the ends of the fabric are clamped, the second motor 23 is started. The output end of the second motor 23 rotates forward to drive the twin screws 22 to rotate forward. Under the sliding cooperation of the frame 1, the screw block 21 in the longitudinal hole 20 drives the bearing plate 19 and the tension frame 2 to move. At this time, the two tension frames 2 are away from each other. In this state, the tension of the fabric can be increased by pulling the two ends of the fabric.

[0056] The output end of motor 23 is reversed to drive the twin screws 22 to reverse. Under the sliding cooperation of the frame 1, the screw block 21 in the longitudinal hole 20 drives the bearing plate 19 and the tension frame 2 to move. At this time, the two tension frames 2 are close to each other. In this state, the tension of the fabric can be reduced, and when the side of the sector tooth 11 is reversely engaged with the rack 12, the contact and cooperation between the ridge 24 and the groove 4 is ended, and the release of the fabric is completed, which further improves the efficiency of the device in releasing the fabric.

[0057] Example 7: Reference Figures 1-8, two gear three 25 are rotatably connected to both sides of the bottom of the carrying plate 19, and two bearing bars 45 are connected to the frame 1 to support the bottom of the gear three 25. Each gear three 25 is arranged toward a rack two 26, and the end of the rack two 26 is rotatably connected to the frame 1. The bearing bar 45 is arranged adjacent to the end of the rack two 26, and the middle top surface of the rack two 26 is arranged toward the center of the frame 1. The other end of the rack two 26 away from the tension frame 2 is arranged above its end, and the bottom of the other end of the rack two 26 is in contact with the output end of the adjustment mechanism, and the bottoms of the two convex strips 24 are arranged opposite to each other.

[0058] The principles and beneficial effects of the above scheme are:

[0059] When the two ends of the fabric are clamped, as the two tension frames 2 move away from each other, the gear three 25 connected to the bottom of the support plate 19 is rotated and meshed with the rack two 26. The rack two 26 applies an upward thrust to the support plate 19 through the gear three 25. The screw block 21 slides downward relative to the support plate 19 in the longitudinal hole 20, thereby applying an upward thrust to the spring 6. Since the end of the fabric has been clamped at this time, the spring 6 further applies an upward thrust to the base 3, further completing the complete clamping of the end of the fabric. The rack two 26 is tilted in the device, so when the distance between the two tension frames 2 increases, the pressure applied to the fabric by the base 3 is further increased. Therefore, under the action of higher tension, the end of the fabric has a higher clamping force, thereby ensuring that the fabric will not fall off during testing, thereby improving the safety of the device when in use;

[0060] After the test is completed, the gear 3 25 and the rack 2 26 are reversely meshed and connected, and the screw block 21 slides upward relative to the carrier plate 19 in the longitudinal hole 20, ending the downward pressure on the spring 6, thereby facilitating the contact and cooperation between the ridge 24 and the groove 4, preventing the two from getting stuck, and allowing the end of the fabric to be quickly released.

[0061] The function of the bearing bar 45 on the frame 1 is to temporarily support the gear 3 25 when the gear 3 25 and the rack 2 26 are not engaged, so as to prevent the initial clamping failure of the device for the fabric end. The meshing connection between the gear 3 25 and the rack 2 26 is used to increase or decrease the elastic force of the spring 6. Compared with directly using the roller to slide with the inclined plate, the wear of the plate can be avoided, and the lubrication of the roller can be avoided, thereby reducing the difficulty of device maintenance.

[0062] The device can be set to complete the fixation of the end of the fabric before applying tension, that is, the rack 12 is set to end the contact and cooperation with the sector tooth 11 when the tension is applied. Since the sector tooth 11 ends the meshing connection with the rack 12 and needs to perform the next reverse meshing connection, a tooth at the bottom of the sector tooth 11 will contact the top of the inner tooth of the rack 12, but there will be no meshing between the two components, and the sector tooth 11 will not be caused to rotate. Even if the sector tooth 11 is subjected to pressure from the rack 12, it will only cause the sector tooth 11 to swing very slightly, and the ridge 24 will not fall out of the groove 4. The setting of the spring 6 can buffer the base 3 and absorb the pressure from the ridge 24, so that the end of the fabric is always kept in the groove 4.

[0063] Example 8: Reference Figures 1-8 The adjustment mechanism includes: a lifting piece 27, which is slidably connected to the frame 1, and the tops of both ends of the lifting piece 27 are in contact with the bottom of a connecting shaft 28. Each connecting shaft 28 is connected to the top of two adjacent racks 26. A bolt 30 is threaded on the lifting piece 27, and the bolt 30 is rotatably connected to the frame 1.

[0064] The end of the second rack 26 is rotatably connected to the mounting shaft 31 on the frame 1. The mounting shaft 31 is concentrically arranged with the second torsion spring 29. The two ends of the second torsion spring 29 are respectively connected to the frame 1 and the second rack 26.

[0065] The principles and beneficial effects of the above scheme are:

[0066] Different fabrics have different strengths. Therefore, when clamping their ends, comprehensive consideration must be given to prevent damage that would cause inaccurate test results. Therefore, when the fabric strength is low, the lifting piece 27 needs to be adjusted downward. At this time, the bolt 30 is rotated forward, and the lifting piece 27 threadedly connected thereto moves downward relative to the tension frame 2 under the sliding cooperation of the frame 1. Then, the connecting shaft 28 in contact with the top of the lifting piece 27 moves downward, and the end of the rack 26 rotates counterclockwise relative to the mounting shaft 31. The torsion spring 29 releases its elastic potential energy, and the distance between the other end of the rack 26 and the top of the frame 1 decreases. As a result, when the rack 26 is meshed with the gear 3 25, the pressure exerted on the base 3 decreases.

[0067] When the fabric is strong, the lifting plate 27 needs to be adjusted upward. At this time, the bolt 30 is reversed, and the lifting plate 27 threadedly connected thereto moves upward relative to the tension frame 2 under the sliding cooperation of the frame 1. Then, the connecting shaft 28 in contact with the top of the lifting plate 27 moves upward, and the end of the second rack 26 rotates clockwise relative to the mounting shaft 31. The second torsion spring 29 stores elastic potential energy, and the distance between the other end of the second rack 26 and the top of the frame 1 increases. As a result, when the second rack 26 is meshed with the third gear 25, the pressure applied to the base 3 increases.

[0068] Lowering the other end of rack 26 can prevent the device from causing damage to the end of the fabric during testing, avoiding changes in its internal tension causing inaccurate test results. Raising the other end of rack 26 can increase the clamping force on the end of the fabric, preventing the fabric from falling off during testing, and further improving the accuracy of the device during testing.

[0069] The setting of torsion spring 29 can apply auxiliary external force to rack 26 and fix it, thereby preventing it from shaking up and down when it is engaged with gear 3 25, thereby preventing the pressure applied by base 3 on the fabric from changing and preventing the fabric from falling during automatic clamping.

[0070] Example 9: Reference Figures 1-8 The side wall of the grinding roller 18 is provided with a plurality of grooves 32, and the side wall of the grooves 32 is provided with the ends of a plurality of exhaust holes 33. The other end of the exhaust hole 33 is provided on the inner wall of the exhaust chamber 34 in the grinding roller 18. The exhaust chamber 34 is connected to the end of the connecting pipe 17. The end of the pump casing 35 is rotatably sealed on the side wall of the connecting pipe 17. The pump casing 35 is fixed to the bottom of the lifting frame 15. The other end of the pump casing 35 is rotatably sealed with the side wall of the pipe 36. The pipe 36 is rotatably connected to the connecting pipe 17. The end of a plurality of exhaust holes 37 is provided on the side wall of the connecting pipe 17. The other end of the exhaust holes 37 is arranged toward the pump casing 35. The ends of a plurality of fan blades 38 are connected to the pipe 36. The fan blades 38 are arranged in the pump casing 35. The bottom of the pump casing 35 is connected to the end of a metal exhaust pipe 39.

[0071] The principles and beneficial effects of the above scheme are:

[0072] When the grinding roller 18 is grinding, its side wall contacts the surface of the fabric. To prevent debris on the fabric from being unable to be removed during testing, a second groove 32 is provided on the side wall of the grinding roller 18. An air extraction hole 33 is provided on the side wall of the second groove 32 to connect the air extraction chamber 34 of the grinding roller 18 to the outside world. After the motor 16 is started, the air pressure in the connecting pipe 17 is reduced, and the debris polished off the fabric enters the air extraction hole 33 through the second groove 32 and then enters the connecting pipe 17.

[0073] The principle of reducing the air pressure in the connecting pipe 17 is as follows: the rotation of the pipe 36 drives the rotation of the fan blade 38, thereby reducing the air pressure in the pump housing 35, and synchronously reducing the air pressure in the exhaust hole 37, so that debris can enter the interior of the metal exhaust pipe 39 through the air extraction hole 33, the connecting pipe 17 and the exhaust hole 37. The metal exhaust pipe 39 can be absorbed by a hose and a storage device in the prior art, such as a storage box. The removal of debris can avoid the formation of a buffer layer on the surface of the fabric during the wear resistance test, thereby avoiding changes in the friction conditions between the grinding roller 18 and the fabric; timely cleaning of debris can also accurately judge the friction effect;

[0074] Since the pump housing 35 is fixed on the lifting frame 15 and is rotationally sealed with the connecting pipe 17 and the pipeline 36, the sealing effect of the pump housing 35 is increased, and the efficiency of the device in collecting debris is further improved.

[0075] Example 10: Reference Figures 1-8 The side wall of the pipe 36 is connected to the inner wall of the gear ring 40, the gear ring 40 is meshed with the gear four 41 through the intermediate gear 46, the intermediate gear 46 is rotatably connected to the lifting frame 15, the gear four 41 is connected to the rotating shaft 42, the rotating shaft 42 is rotatably connected to the lifting plate 15, the rotating shaft 42 is connected to the gear five 43, and the gear five 43 is meshed with the gear six 44 on the output shaft of the motor 16.

[0076] The principles and beneficial effects of the above scheme are:

[0077] When the mechanism is working, gear six 44 on the output shaft of the motor 16 rotates and drives the gear five 43 meshing with it to reverse. The gear five 43 drives the gear four 41 to reverse on the lifting plate 15 through the rotating shaft 42. The gear four 41 drives the gear ring 40 to reverse through the intermediate gear 46. Therefore, the rotation of the pipeline 36 is opposite to that of the motor 16, and the rotation direction of the fan blade 38 is opposite to that of the connecting pipe 17, which can achieve the suction of debris.

[0078] Example 11: Reference Figures 1-8 The other end of the fan blade 38 is connected to a discharge cone, and the tip of the discharge cone is set toward the inner wall of the pump casing 35. The discharge cone, fan blade 38 and pipe 36 are all made of conductive materials, the connecting pipe 17 and the pump casing 35 are made of insulating materials, the pipe 36 is electrically connected to one electrode of the power supply through a conductive ring, and the side wall of the metal exhaust pipe 39 is electrically connected to the other electrode of the power supply.

[0079] The principles and beneficial effects of the above scheme are:

[0080] Due to the different composition of fabrics, some fabrics will experience electrostatic adsorption when polishing. At this time, one electrode of the power supply supplies power to the pipe 36 through the conductive ring, and the other electrode of the power supply supplies power to the metal exhaust pipe 39. Since the discharge cone, fan blades 38 and pipe 36 are all made of conductive materials, and the connecting pipe 17 and the pump housing 35 are made of insulating materials, when the fan blades 38 drive the discharge cone to rotate to a position coaxial with the metal exhaust pipe 39, the tip of the discharge cone begins to discharge, thereby removing static electricity in the debris and preventing the debris from being adsorbed inside the mechanism and causing blockage.

[0081] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
