Description

Technical Field

[0001] The invention relates to the technical field of clothing fabric detection equipment, and in particular to a fabric elasticity detection device for clothing manufacturing. Background Art

[0002] Clothing manufacturing is the process of processing various types of textile fabrics into clothing products through design, cutting, sewing and other processes. Fabric elasticity testing is a key quality control link in the clothing manufacturing process. By applying external forces such as stretching, squeezing or impact to the fabric, its elastic deformation ability and elastic recovery rate and other fabric performance indicators are measured to evaluate the wearing comfort and durability of the fabric. At present, the elasticity testing method of clothing fabrics generally adopts stretching and pressure testing. For example, a textile fabric elasticity testing device disclosed in application publication number CN116539453B can stretch textile fabrics and test their elasticity under different pressures.

[0003] However, the fabric detection devices used in clothing manufacturing often still have the following problems: It is difficult for the fabric elasticity detection device to perform gradient continuous pressure detection on clothing fabrics. When the detection pressure needs to be adjusted, that is, when performing segmented pressure detection on clothing fabrics, it is usually necessary to manually replace the weight block used to apply pressure, which makes the pressure detection operation of the fabric more complicated, resulting in low efficiency of fabric elasticity detection, and it is impossible to perform corresponding segmented pressure detection on fabrics in different extension conditions, resulting in poor adequacy of clothing fabric elasticity detection, and thus it is difficult to accurately reflect the elastic properties of clothing fabrics; During the stretching and extension test of clothing fabrics, the clothing fabrics need to be fully fixed before being stretched and extended. The clothing fabrics are usually fixed by clamping the edges of the fabrics. When the clothing fabrics are stretched, the clamping structure is prone to tearing or even damaging the clothing fabrics, resulting in inconsistent overall stretching of the clothing fabrics, which in turn affects the elasticity of the clothing fabrics and the accuracy of the test.

[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] Example: Refer to Figures 1 to 10 A fabric elasticity detection device for clothing manufacturing, comprising: a base 1 and a gradient detection component 5, a platform frame 9 is fixedly connected to the bottom surface of the detection frame 2, the platform frame 9 is used to place the flattened fabric, the upper end surface of the base 1 is fixedly connected to the detection frame 2, the top surface of the detection frame 2 is fixedly installed with an optical detector 3, the side wall of the detection frame 2 is slidably connected to two hollow extension rollers 4, the two hollow extension rollers 4 are used to fix and extend the stretched fabric; The gradient detection assembly 5 includes two support shaft seats 51 fixedly connected to the inner top surface of the detection frame 2, the lower ends of the two support shaft seats 51 are slidably connected with a rotating shaft 52, the outer peripheral wall of the rotating shaft 52 is fixedly connected with an incomplete gear set 53, the incomplete gear set 53 includes three incomplete gears, in the horizontal direction toward the cylinder push rod 61, the number of teeth on the three incomplete gears is arranged in an increasing manner, a support guide rail 54 is fixedly connected to the inner top surface of the detection frame 2, a lifting column 55 is slidably connected to the inner side of the support guide rail 54, a strip protrusion 11 is fixedly connected to the outer peripheral wall of the lifting column 55, a slide groove 12 is provided on the inner side of the support guide rail 54, the strip protrusion 11 and the slide groove 12 are slidably matched, a vertical tooth row 56 is fixedly connected to the outer peripheral wall of the lifting column 55, the vertical tooth row 56 is meshed with the incomplete gear set 53, and an impact block 57 is fixedly connected to the lower end of the lifting column 55; The lifting electric cylinder 72 drives the two hollow stretching rollers 4 and the fabric to move upward. When the hollow stretching rollers 4 pass through the arc-shaped segment slide hole of the limit slide hole 71, the two hollow stretching rollers 4 gradually move back and forth and stretch the flat fabric, so that the fabric begins to be in a stretched and extended state. The servo motor 62 drives the spline shaft 64, the limit sleeve 63 and the rotating shaft 52 to rotate. When the rotating shaft 52 rotates, it can drive the incomplete gear set 53 to rotate synchronously. When the incomplete gears in the incomplete gear set 53 are meshed with the vertical gear row 56, the lifting column 55 can be driven to move upward. When the incomplete gears are no longer meshed with the vertical gear row 56, the lifting column 55 can fall freely, and the impact block 57 at the lower end of the lifting column 55 impacts the fabric in the stretched and extended state, so as to complete the pressure detection of the fabric. A shift component 6 is fixedly installed on the top of the detection frame 2. The shift component 6 is used to drive the incomplete gear set 53 to move horizontally. The shift component 6 includes a cylinder push rod 61 and a servo motor 62 fixedly installed on the top of the detection frame 2. The output end of the cylinder push rod 61 is fixedly connected to one end of the rotating shaft 52 through a bearing ring, and the other end of the rotating shaft 52 is fixedly connected to a limiting sleeve 63. The inner wall of the limiting sleeve 63 is slidably connected with a spline shaft body 64. The end of the spline shaft body 64 away from the limiting sleeve 63 is fixedly connected to the output end of the servo motor 62 through a coupling. The shift component 6 also includes a cylinder push rod 61 and a servo motor 62 fixedly installed on the top of the detection frame 2. The output end of the cylinder push rod 61 is fixedly connected to one end of the rotating shaft 52 through a bearing ring, and the other end of the rotating shaft 52 is fixedly connected to a limiting sleeve 63. The inner wall of the limiting sleeve 63 is slidably connected to a spline shaft body 64. The end of the spline shaft body 64 away from the limiting sleeve 63 is fixedly connected to the output end of the servo motor 62 through a coupling. The shift component 6 also includes a cylinder push rod 61 and a servo motor 62 fixedly installed on the top of the detection frame 2. The sliding cavity 65 inside the column 55, the inner side of the sliding cavity 65 is slidably connected with a stopper 66, a pressure spring 67 is fixedly connected between the stopper 66 and the bottom surface of the sliding cavity 65, a touch-pressure switch 68 is fixedly installed on the top surface of the sliding cavity 65, the stopper 66 and the touch-pressure switch 68 are selectively squeezed and matched, and the touch-pressure switch 68 is electrically connected to the cylinder push rod 61. Specifically, a through groove is opened on the circumferential side wall of the lifting column 55, the through groove is connected to the sliding cavity 65, and a magnetic cover plate is movably connected to the circumferential side wall of the lifting column 55 at the through groove, so as to maintain or replace part of the shift component structure in the sliding cavity 65; After impacting the fabric, the impact block 57 will encounter resistance and rebound, and the stop block 66 will continue to move downward due to its own inertia. At the same time, the lifting column 55 rebounds and rises, and the stop block 66 can contact the squeeze switch 68, so that the cylinder push rod 61 starts to run and drives the rotating shaft 52 and the incomplete gear set 53 to move horizontally, so that the incomplete gear with more teeth in the incomplete gear set 53 can mesh with the vertical gear row 56, so that the gear shift of the incomplete gear set 53 relative to the vertical gear row 56 can be completed. Since the number of teeth on the three incomplete gears is in the horizontal direction toward the cylinder push rod 61, The gears are arranged in increments, so that the number of teeth meshing between the incomplete gear set 53 and the vertical gear row 56 can be increased, and then the lifting column 55 can be driven to rise a higher distance when the incomplete gear set 53 rotates. According to Newton's second law, under the same air resistance, friction resistance and gravity conditions, the impact force of the impact block 57 is positively correlated with its falling height. The impact force of the impact block 57 falling freely is greater, so the fabric can be subjected to gradient continuous segmented pressure detection without replacing the impact block 57 that applies pressure, which effectively simplifies the fabric pressure detection operation and improves the fabric elasticity detection efficiency; Specifically, during the process of the impact block 57 falling freely multiple times and impacting the fabric, the optical detector 3 can shoot and analyze the deformation, stretching and rebound of the fabric throughout the process to detect the elasticity of the fabric under different pressure impacts; Specifically, the spline shaft 64 can slide relative to the limiting sleeve 63, and the spline shaft 64 is provided with a plurality of spline teeth, and the inner hole of the limiting sleeve 63 is provided with a plurality of grooves corresponding to the spline teeth, so that when the spline shaft 64 rotates, the limiting sleeve 63 can be driven to rotate synchronously; Specifically, when the PLC controller 85 detects that the touch pressure switch 68 is triggered three times, the PLC controller 85 can directly control the cylinder push rod 61 to reset to the initial position, so that the incomplete gear set 53 can be reset synchronously after the switching is completed in sequence, so as to perform pressure detection on subsequent fabrics.

[0029] Two winding and fixing assemblies 7 are provided on the side wall of the detection frame 2. The winding and fixing assemblies 7 include two limiting sliding holes 71 provided on the side wall of the detection frame 2. The hollow extension roller 4 slides with the side wall of the detection frame 2 through the limiting sliding holes 71. A lifting electric cylinder 72 is fixedly installed on the upper end surface of the base 1. A telescopic cylinder 73 is fixedly connected to the output end of the lifting electric cylinder 72. A T-shaped frame 74 is slidably connected to the two axial side walls of the telescopic cylinder 73. A plurality of tension springs 75 are fixedly connected between the T-shaped frame 74 and the inner wall of the telescopic cylinder 73. When the lifting electric cylinder 72 is controlled to drive the telescopic cylinder 73 to move downward, that is, when the two hollow extension rollers 4 are reset to the bottom under the limiting action of the limiting sliding holes 71, the tension springs 75 can automatically pull the two T-shaped frames 74 to reset, so that the reset movement process of the two hollow extension rollers 4 is more stable and smooth. The ends of the two T-shaped frames 74 located outside the telescopic cylinder 73 are respectively rotatably connected to the ends of the two hollow extension rollers 4 through one-way bearings; Specifically, since the T-shaped frame 74 is rotatably connected to the hollow stretching roller 4 through a one-way bearing, after the hollow stretching roller 4 fully winds and fixes the end of the cloth, the hollow stretching roller 4 cannot rotate in the opposite direction relative to the T-shaped frame 74, thereby preventing the cloth from loosening and falling off due to the reverse rotation of the hollow stretching roller 4, ensuring the stability of the winding and fixing of the cloth by the hollow stretching roller 4, so as to facilitate the stretching and extending operation of the cloth; The ends of the two hollow stretching rollers 4 are fixedly connected with a rotating fixed component 10, and the rotating fixed component 10 is used to fix the cloth to the outer peripheral wall of the hollow stretching roller 4 in a winding manner. The rotating fixed component 10 includes a transmission gear 101 fixedly connected to the end of the hollow stretching roller 4, and a small electric push rod 102 is fixedly installed on the inner wall of the detection frame 2. The output end of the small electric push rod 102 is fixedly connected to a toothed plate frame 103, and the transmission gear 101 is meshed with the toothed plate on the toothed plate frame 103. A plurality of adsorption through holes 104 are opened on the axial side wall of the hollow stretching roller 4, and the plurality of adsorption through holes 104 are located in the middle of the hollow stretching roller 4. Two control pistons 105 are sealed and slidably connected to the inner wall of the hollow stretching roller 4, and a magnetic ring 106 is fixedly connected to the middle of the two control pistons 105. Two stepped magnetic sheets 107 with a symmetrical structure are fixedly connected to the outer wall of the platform frame 9, and the stepped magnetic sheets 107 and the magnetic ring 106 are arranged to attract each other with opposite poles; When the two hollow stretching rollers 4 move upward under the limiting action of the vertical slide hole of the limiting slide hole 71, the meshing transmission cooperation between the transmission gear 101 and the toothed plate on the toothed plate frame 103 can be used to complete the self-rotation of the hollow stretching roller 4. At the same time, when the hollow stretching roller 4 moves upward, the magnetic attraction between the magnetic ring 106 and the stepped magnetic sheet 107 can be used to drive the control piston 105 to move by itself, so that the two control pistons 105 can move back and forth in the hollow stretching roller 4 in a sealed manner, so that the air pressure near the center position inside the hollow stretching roller 4 is reduced, thereby forming a negative pressure environment at a plurality of adsorption through holes 104, and making the fabric initially close to the outer peripheral wall of the hollow stretching roller 4, and at the same time, the hollow stretching roller 4 in the self-rotating state is used to perform winding adsorption and fixation on both ends of the fabric, thereby replacing the method of directly clamping the ends of the fabric, and can effectively maintain the consistency of the overall stretching degree of the fabric, which is conducive to ensuring the elasticity and detection accuracy of the fabric, and can avoid damage to the fabric during the stretching process; Specifically, the PLC controller 85 can control the synchronous operation of the two lifting electric cylinders 72 on the base 1, so that the two lifting electric cylinders 72 can drive the two hollow stretching rollers 4 to move synchronously in the same direction, so as to maintain the stability of the two hollow stretching rollers 4 in fixing and stretching the cloth; Specifically, after the elasticity test of the fabric is completed, the gear plate frame 103 can be driven to move by controlling the small electric push rod 102, so that the gear plate frame 103 is away from the transmission gear 101, that is, the gear plate frame 103 is no longer engaged with the transmission gear 101, and then the two hollow stretching rollers 4 can be driven to reset by controlling the lifting electric cylinder 72, so as to facilitate the elasticity test of subsequent batches of fabrics; Specifically, a plurality of adsorption through holes 104 are provided and are evenly arranged in an array on the circumferential side wall of the hollow stretching roller 4. When the hollow stretching roller 4 rotates and winds and fixes the cloth, the cloth is gradually adsorbed by the plurality of adsorption through holes 104. After completely covering the hollow stretching roller 4, the hollow stretching roller 4 will continue to rotate, so that the cloth can continue to be wound and the two control pistons 105 inside the hollow stretching roller 4 are in a nearly sealed state, thereby allowing the cloth to be fully attached to the outer circumferential wall of the hollow stretching roller 4.

[0030] The end of one of the hollow stretching rollers 4 is rotatably connected to an intermittent stretching assembly 8, and the intermittent stretching assembly 8 includes an arc gear 81 rotatably connected to the end of the hollow stretching roller 4, and a plurality of arc-shaped power-connecting sheets 82 are fixedly connected to the arc gear 81. The limit sliding hole 71 is composed of a vertical section sliding hole, an arc-shaped section sliding hole and an inclined section sliding hole. The outer wall of the detection frame 2 is fixedly connected to a power-connecting plate 83, and the power-connecting plate 83 is located below the inclined section sliding hole and is parallel to the inclined section sliding hole. A plurality of arc-shaped power-connecting sheets 82 selectively contact and cooperate with the power-connecting plate 83, and a plurality of cylindrical stoppers 84 are fixedly connected to the upper end surface of the power-connecting plate 83, and the cylindrical stoppers 84 mesh with the concave tooth profile of the arc gear 81. A PLC controller 85 is fixedly installed on the outer wall of the detection frame 2, and the PLC controller 85, a plurality of arc-shaped power-connecting sheets 82, a power-connecting plate 83, a lifting electric cylinder 72, and a servo motor 62 are electrically connected to an external power supply; When the two hollow stretching rollers 4 move relative to the inclined section slide hole in the limit slide hole 71, the arc gear 81 can mesh with a plurality of cylindrical blocks 84 and intermittently rotate relative to the hollow stretching roller 4. When the arc-shaped power connection piece 82 on the arc gear 81 contacts the power connection plate 83, the PLC controller 85 can control the lifting cylinder 72 to stop running, so that the cloth is maintained in the corresponding stretched and extended state, so as to achieve intermittent stretching and extension of the cloth. After the pressure detection of the cloth by the impact block 57 is performed, the PLC controller 85 can immediately transmit an operation signal to the lifting cylinder 72, so that the lifting cylinder 72 continues to drive the two hollow stretching rollers 4 and the cloth to move upward, thereby making the two hollow stretching rollers 4 continue to periodically move in opposite directions synchronously and make the cloth further stretched and extended, and perform segmented pressure detection on the cloth again, so that the corresponding segmented pressure detection can be performed on the cloth in different extension conditions, effectively improving the adequacy of the elastic detection of the cloth, and being able to more accurately reflect the elastic performance of the cloth; Specifically, the arc gear 81 is provided with a plurality of arc-shaped convex teeth, and a plurality of arc-shaped power connection plates 82 are respectively fixed to the outer walls of the arc-shaped convex teeth. When the cylindrical stopper 84 is meshed with the concave tooth profile of the arc gear 81, the arc-shaped power connection plates 82 on the arc-shaped convex teeth just contact and cooperate with the power connection plate 83. Specifically, during the sliding process of the hollow stretching roller 4 relative to the inclined section slide hole in the limiting slide hole 71, the hollow stretching roller 4 can be moved toward the upper side of the detection frame 2 under the limiting action of the inclined section slide hole, so that the two hollow stretching rollers 4 can move back to back while moving upward, thereby stretching the fabric.

[0031] The working principle of the present invention is as follows: When in use, first spread the cloth evenly and place it on the platform frame 9, so that the two ends of the cloth can naturally fall to the two sides of the platform frame 9 and adhere to the outer peripheral walls of the two hollow stretching rollers 4, then control the lifting electric cylinder 72 to start, and drive the telescopic cylinder 73 and the two T-shaped frames 74 to move up through the lifting electric cylinder 72, so that the two hollow stretching rollers 4 can synchronously rise and move under the limiting action of the vertical section slide hole of the limiting slide hole 71, and the hollow stretching roller 4 can use the meshing transmission cooperation of the transmission gear 101 and the toothed plate on the toothed plate frame 103 to complete the self-rotation when moving up, and at the same time, the hollow stretching roller 4 can use the meshing transmission cooperation of the transmission gear 101 and the toothed plate on the toothed plate frame 103 to complete the self-rotation when moving up. The magnetic attraction between the magnetic ring 106 and the stepped magnetic sheet 107 is used to drive the control piston 105 to move, so that the two control pistons 105 can move in a sealed back direction in the hollow stretching roller 4, so that the air pressure near the center of the hollow stretching roller 4 is reduced, and then a negative pressure environment is formed at the plurality of adsorption holes 104, so that the air outside the plurality of adsorption holes 104 can be squeezed into the hollow stretching roller 4, so that the cloth can be initially attached to the outer peripheral wall of the hollow stretching roller 4, and then the hollow stretching roller 4 in a self-rotating state can be used to perform winding adsorption and fixation on both ends of the cloth; After the hollow stretching rollers 4 have completed winding and fixing the fabric, the lifting electric cylinder 72 continues to drive the two hollow stretching rollers 4 and the fabric to move upward. When the hollow stretching rollers 4 pass through the arc-shaped segment slide hole of the limiting slide hole 71, the two hollow stretching rollers 4 gradually move back to back and stretch the flat fabric, so that the fabric begins to be in a stretched and extended state. At this time, the servo motor 62 is controlled to start, and the spline shaft 64, the limiting sleeve 63 and the rotating shaft 52 are driven to rotate by the servo motor 62. When the rotating shaft 52 rotates, it can drive the incomplete gear set 53 to rotate synchronously. When the incomplete gears in the incomplete gear set 53 are meshed with the vertical gear row 56, the lifting column 55 can be driven to move upward. When the incomplete gears are no longer meshed with the vertical gear row 56, the lifting column 55 can fall freely, and the impact block 57 at the lower end of the lifting column 55 impacts the fabric in the stretched and extended state. After impacting the cloth, the impact block 57 will encounter resistance and rebound. During this process, the impact block 66 will continue to move downward due to its own inertia, and the lifting column 55 will rebound and rise, so that the impact block 66 can contact and squeeze the touch switch 68. The touch switch 68 is triggered and generates an electrical signal and transmits it to the PLC controller 85. The PLC controller 85 starts to control the operation of the cylinder push rod 61, so that the cylinder push rod 61 starts to drive the rotating shaft 52 and the incomplete gear set 53 to move horizontally, thereby enabling the incomplete gear set 53 to complete the gear shift relative to the vertical gear row 56. Since the number of teeth on the three incomplete gears is arranged in an increasing manner in the horizontal direction toward the cylinder push rod 61, the number of teeth meshing between the incomplete gear set 53 and the vertical gear row 56 can be increased, and then when the incomplete gear set 53 rotates, the lifting column 55 can be driven to rise a higher distance, that is, the impact force of the free fall of the impact block 57 is greater, so the cloth can be subjected to gradient continuous segmented pressure detection; During the process of the lifting electric cylinder 72 driving the two hollow stretching rollers 4 to move upward, when the two hollow stretching rollers 4 move relative to the inclined section slide hole in the limit slide hole 71, the arc gear 81 can mesh with a plurality of cylindrical blocks 84 and intermittently rotate relative to the hollow stretching roller 4. During this process, when the arc-shaped power connection sheet 82 on the arc gear 81 contacts the power connection board 83, the PLC controller 85 can monitor the power connection status of the power connection board 83 and transmit a signal to the lifting electric cylinder 72, so that the lifting electric cylinder 72 is suspended, and then the lifting electric cylinder 72 can be The fabric is maintained in a corresponding stretched and extended state to achieve intermittent stretching and extension of the fabric. After the impact block 57 is used to perform pressure detection on the fabric, that is, after the PLC controller 85 detects that the touch pressure switch 68 is triggered three times, it can immediately transmit an operation signal to the lifting cylinder 72, so that the lifting cylinder 72 continues to drive the two hollow stretching rollers 4 and the fabric to move upward, so that the two hollow stretching rollers 4 continue to move synchronously in opposite directions periodically and further stretch the fabric, and perform segmented pressure detection on the fabric again.
