Description

Technical Field

[0001] The present 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 transforming various textile fabrics into apparel products through design, cutting, and sewing. Fabric elasticity testing is a key quality control step in the apparel manufacturing process. By applying external forces such as stretching, squeezing, or impacting the fabric, fabric performance indicators such as elastic deformation and elastic recovery are measured to assess the fabric's comfort and durability. Currently, stretch and pressure testing are commonly used to test the elasticity of clothing fabrics. For example, application publication number CN116539453B discloses a textile fabric elasticity testing device that can perform stretch and elasticity tests on textile fabrics under different pressures.

[0003] However, the fabric detection devices used in clothing manufacturing often have the following problems:

[0004] Fabric elasticity testing devices have difficulty performing gradient continuous pressure testing on garment fabrics. When the testing pressure needs to be adjusted, that is, when performing segmented pressure testing on garment fabrics, the weights used to apply pressure usually need to be manually replaced, making the fabric pressure testing operation cumbersome and the fabric elasticity testing efficiency low. Furthermore, it is impossible to perform corresponding segmented pressure testing on fabrics in different stretching conditions, resulting in poor elasticity testing of garment fabrics and difficulty in accurately reflecting the elastic properties of garment fabrics.

[0005] 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 stretching the clothing fabrics, the clamping structure can easily tear or even damage 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.

DETAILED DESCRIPTION

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example: Refer to Figures 1 to 10 A fabric elasticity detection device for clothing manufacturing includes: 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, and the platform frame 9 is used to place flat 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 stretching rollers 4, and the two hollow stretching rollers 4 are used to fix and stretch the fabric;

[0038] The gradient detection assembly 5 includes two support shaft seats 51 fixedly connected to the inner top surface of the detection frame 2, and the lower ends of the two support shaft seats 51 are slidably connected to the rotating shaft 52. The outer peripheral wall of the rotating shaft 52 is fixedly connected to the incomplete gear set 53, and 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 increasing order. The inner top surface of the detection frame 2 is fixedly connected to a support guide rail 54, and the inner side of the support guide rail 54 is slidably connected to a lifting column 55. The outer peripheral wall of the lifting column 55 is fixedly connected to a strip protrusion 11, and a slide groove 12 is provided on the inner side of the support guide rail 54. The strip protrusion 11 slides in cooperation with the slide groove 12. The outer peripheral wall of the lifting column 55 is fixedly connected to a vertical tooth row 56, which meshes with the incomplete gear set 53. The lower end of the lifting column 55 is fixedly connected to an impact block 57;

[0039] 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 limiting 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 limiting 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 gear in the incomplete gear set 53 is engaged with the vertical gear row 56, it can drive the lifting column 55 to move upward. When the incomplete gear is no longer engaged 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.

[0040] 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 64. The end of the spline shaft 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 lifting mechanism. The sliding cavity 65 inside the column 55 has a stopper 66 slidably connected to the inside of the sliding cavity 65. 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. 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, and the through groove is connected to the sliding cavity 65. A magnetic cover plate is movably connected to the circumferential side wall of the lifting column 55 at the through groove to facilitate maintenance or replacement of some shift component structures in the sliding cavity 65.

[0041] 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, thereby making the incomplete gear with more teeth in the incomplete gear set 53 able to mesh with the vertical gear row 56, thus completing the shifting of the incomplete gear set 53 relative to the vertical gear row 56. Since the number of teeth on the three incomplete gears is in the horizontal direction toward the cylinder push rod 61, the gears of the incomplete gear set 53 are arranged in a circle. The incremental arrangement increases the number of teeth meshing between the incomplete gear set 53 and the vertical gear row 56, thereby driving the lifting column 55 to a greater height when the incomplete gear set 53 rotates. According to Newton's second law, under the same conditions of air resistance, friction resistance, and gravity, the impact force of the impact block 57 is positively correlated with its falling height. The impact force of the impact block 57 in free fall is greater, thus enabling gradient and continuous segmented pressure testing of the fabric without having to replace the impact block 57 that applies pressure. This effectively simplifies the fabric pressure testing operation and improves the efficiency of fabric elasticity testing.

[0042] Specifically, during the process of the impact block 57 freely falling and impacting the fabric multiple times, the optical detector 3 can capture and analyze the deformation, stretching, and rebound of the fabric throughout the entire process to detect the elasticity of the fabric under different pressure impacts;

[0043] 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. When the spline shaft 64 rotates, the limiting sleeve 63 can be driven to rotate synchronously.

[0044] 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.

[0045] The two ends of the two T-shaped frames 74 outside the telescopic cylinder 73 are respectively connected to the ends of the two hollow stretch rollers 4 through one-way bearings;

[0046] Specifically, since the T-shaped frame 74 is rotatably connected to the hollow stretching roller 4 via a one-way bearing, after the hollow stretching roller 4 has fully wound and fixed the end of the fabric, the hollow stretching roller 4 cannot rotate in the opposite direction relative to the T-shaped frame 74. This prevents the fabric from loosening and falling due to the reverse rotation of the hollow stretching roller 4, ensuring that the hollow stretching roller 4 is firmly wound and fixed to the fabric, thereby facilitating the stretching operation of the fabric.

[0047] The ends of the two hollow stretching rollers 4 are fixedly connected with a rotating fixed component 10, which 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 gear plate frame 103, and the transmission gear 101 is meshed with the gear plate on the gear 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 position 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. The middle parts of the two control pistons 105 are fixedly connected with a magnetic ring 106. The outer wall of the platform frame 9 is fixedly connected with two stepped magnetic sheets 107 with a symmetrical structure. The stepped magnetic sheet 107 and the magnetic ring 106 are arranged to attract each other with opposite poles;

[0048] When the two hollow stretching rollers 4 are lifted up under the limiting action of the vertical slide holes of the limiting slide holes 71, the meshing transmission of 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 a sealed manner inside the hollow stretching roller 4, so that the air pressure near the center position inside the hollow stretching roller 4 is reduced, thereby forming a negative pressure environment at the several adsorption through holes 104, and making the fabric initially adhere to the outer peripheral wall of the hollow stretching roller 4. At the same time, the hollow stretching roller 4 in the self-rotating state is used to perform winding adsorption and fixation on the two ends of the fabric, thereby replacing the method of directly clamping the ends of the fabric, which can effectively maintain the consistency of the overall stretching degree of the fabric, is conducive to ensuring the elasticity and detection accuracy of the fabric, and can avoid damage to the fabric during the stretching process;

[0049] Specifically, the PLC controller 85 can control the synchronous operation of the two lifting cylinders 72 on the base 1, so that the two lifting cylinders 72 can drive the two hollow stretching rollers 4 to move synchronously in the same direction to maintain the stability of the two hollow stretching rollers 4 in fixing and stretching the cloth;

[0050] Specifically, after the fabric elasticity test is completed, the small electric push rod 102 can be controlled to drive the toothed plate frame 103 to move so that the toothed plate frame 103 is away from the transmission gear 101, that is, the toothed plate frame 103 is no longer engaged with the transmission gear 101. Then, the lifting cylinder 72 can be controlled to drive the two hollow stretching rollers 4 to return to their original position, so that the elasticity test of subsequent batches of fabrics can be carried out.

[0051] Specifically, a plurality of adsorption through holes 104 are provided and 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 continues 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 adhered to the outer circumferential wall of the hollow stretching roller 4.

[0052] The end of one of the hollow stretching rollers 4 is rotatably connected to an intermittent stretching component 8, which includes an arc gear 81 rotatably connected to the end of the hollow stretching roller 4, and a plurality of arc-shaped power connection pieces 82 are fixedly connected to the arc gear 81. The limiting slide hole 71 is composed of a vertical section slide hole, an arc section slide hole and an inclined section slide hole. The outer wall of the detection frame 2 is fixedly connected to a power connection plate 83, which is located below the inclined section slide hole and is parallel to the inclined section slide hole. A plurality of arc-shaped power connection pieces 82 selectively contact and cooperate with the power connection plate 83, and a plurality of cylindrical stoppers 84 are fixedly connected to the upper end surface of the power connection plate 83. 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. The PLC controller 85, a plurality of arc-shaped power connection pieces 82, the power connection plate 83, the lifting cylinder 72, the servo motor 62 are electrically connected to an external power supply;

[0053] When the two hollow stretching rollers 4 move relative to the inclined section slide holes in the limit slide holes 71, the circular arc gear 81 can mesh with the plurality of cylindrical blocks 84 and intermittently rotate relative to the hollow stretching rollers 4. When the arc-shaped power connection piece 82 on the circular arc gear 81 contacts the power connection plate 83, the PLC controller 85 can control the lifting cylinder 72 to suspend operation, so that the fabric is maintained in the corresponding stretched and extended state, thereby achieving intermittent stretching and extension of the fabric. After the impact block 57 is used to perform pressure testing on the fabric, the PLC controller 85 can immediately transmit an operating signal to the lifting cylinder 72, so that the lifting cylinder 72 continues to drive the two hollow stretching rollers 4 and the fabric upward, thereby causing the two hollow stretching rollers 4 to continue to periodically move synchronously in opposite directions and further stretch and extend the fabric, and then perform segmented pressure testing on the fabric again, so that the fabric in different stretching conditions can be subjected to corresponding segmented pressure testing, effectively improving the adequacy of the fabric elasticity testing and more accurately reflecting the fabric elasticity performance.

[0054] 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 block 84 is engaged 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.

[0055] 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.

[0056] The working principle of the present invention is as follows:

[0057] 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 hang down to the two sides of the platform frame 9 and stick to the outer peripheral wall 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 complete its self-rotation by utilizing the meshing transmission cooperation of the transmission gear 101 and the tooth plate on the tooth plate frame 103 when moving up. The magnetic attraction between the magnetic ring 106 and the stepped magnetic sheet 107 drives the control piston 105 to move, so that the two control pistons 105 can move in a sealed manner in opposite directions within the hollow stretching roller 4, thereby reducing the air pressure near the center of the hollow stretching roller 4, thereby forming a negative pressure environment 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 initially adhere to the outer peripheral wall of the hollow stretching roller 4, and then the hollow stretching roller 4 in a rotating state can be used to perform winding adsorption and fixation on both ends of the cloth;

[0058] 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 sliding holes of the limiting sliding holes 71, the two hollow stretching rollers 4 gradually move back to back and stretch the 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 servo motor 62 drives the spline shaft 64, the limiting 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 gear in the incomplete gear set 53 is engaged with the vertical gear row 56, it can drive the lifting column 55 to move upward. When the incomplete gear is no longer engaged 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.

[0059] After impacting the fabric, the impact block 57 encounters resistance and rebounds. During this process, the stop block 66 continues to move downward due to its own inertia, while the lifting column 55 rebounds and rises, allowing the stop block 66 to contact the squeeze switch 68. The squeeze switch 68 is triggered and generates an electrical signal that is transmitted to the PLC controller 85. The PLC controller 85 then starts to control the operation of the cylinder push rod 61, causing the cylinder push rod 61 to start driving the rotating shaft 52 and the incomplete gear set 53 to move horizontally, thereby causing 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 increases. As the incomplete gear set 53 rotates, the lifting column 55 can be driven to rise a greater distance. That is, the impact force of the free fall of the impact block 57 is greater, thereby enabling gradient and continuous segmented pressure testing of the fabric.

[0060] 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 circular arc gear 81 can mesh with a number of cylindrical blocks 84 and intermittently rotate relative to the hollow stretching roller 4. During this process, when the arc-shaped power connection piece 82 on the circular arc gear 81 contacts the power connection plate 83, the PLC controller 85 can monitor the power connection status of the power connection plate 83 and transmit a signal to the lifting electric cylinder 72, so that the lifting electric cylinder 72 stops running, thereby 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 operating 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 and extend the fabric, and perform segmented pressure detection on the fabric again.
