Description

Technical Field

[0001] This invention relates to the field of garment stretch testing, specifically to stretching equipment for garment production based on big data technology. Background Technology

[0002] Stretch testing equipment for garment production is a specialized device used in garment manufacturing to test the mechanical properties of fabrics. The equipment has a built-in data acquisition module that can analyze the clamping parameters (such as force and stroke) of different fabrics through big data analysis and automatically match the optimal clamping scheme. At the same time, the test data is uploaded to a cloud database to provide data support for subsequent fabric selection. Its core function is to test the breaking strength, elongation and other indicators of the fabric by clamping and stretching the sample to determine whether the fabric meets the production process or quality standards. It is one of the key quality inspection devices to ensure the quality of garments.

[0003] Most of the clamping mechanisms in commercially available stretching equipment for garment production use rigid structures with fixed dimensions. These structures can only accommodate standard fabric samples with uniform thickness and regular contours. For fabrics with uneven thickness that are common in garment production (such as spliced ​​garment pieces and functional fabrics with localized thickening), traditional equipment cannot adaptively adjust the clamping force and position, easily resulting in problems such as the thick side not being clamped tightly and the thin side being torn. Furthermore, for irregularly shaped fabrics with transitional slopes (such as neckline blanks and scraps), the rigid clamping structure cannot conform to the fabric contour, which not only easily leads to sample loosening and slippage but may also cause fabric damage due to hard compression. Ultimately, this limits the equipment's ability to test diverse fabrics in garment production and makes it difficult to meet the diverse needs of actual production scenarios.

[0004] Secondly, the clamping anti-loosening design of traditional equipment mostly relies on manual locking or simple buckles. During the tensile testing process, the reverse force generated by the fabric can easily loosen the clamping structure, causing the test data to deviate due to sample slippage. Some equipment uses electrical control to prevent loosening, but in the dusty and high-frequency operation environment of the workshop, the failure rate of electrical components is high, and maintenance costs and downtime risks increase simultaneously. At the same time, the unlocking process of traditional equipment often requires step-by-step operation (such as loosening the buckle first and then adjusting the clamp), which is cumbersome and can slow down the overall efficiency of fabric quality inspection.

[0005] Therefore, there is a need to provide stretching equipment for garment production based on big data technology, which aims to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of existing technologies, the purpose of this invention is to provide a stretching device for garment production based on big data technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tensile testing machine housing and a lifting device based on big data technology for garment production, wherein the lifting device is disposed on the top of the tensile testing machine housing, and a drive component, an anti-reverse component, and a clamping component are symmetrically arranged on the lifting device and the tensile testing machine housing; The drive assembly includes two positioning blocks. One positioning block is fixedly connected to the top of the tensile testing machine housing, and the other positioning block is fixedly connected to the lifting device. A connecting plate is fixedly connected to the outer wall of both positioning blocks. A dustproof shell is fixedly connected to the side of each connecting plate away from the positioning block. A strip-shaped groove is formed on the side of each connecting plate near the dustproof shell. A drive rod is rotatably connected inside the dustproof shell. A first gear disk is fixedly connected to the middle of the drive rod. A rack block is slidably connected inside the strip-shaped groove. A rotating handle is fixedly connected to the outer wall of the drive rod.

[0008] Preferably, the drive assembly further includes a rotating rod, which is rotatably connected inside the dustproof housing. A second gear disk is slidably connected to the middle of the rotating rod, and helical gears are symmetrically fixedly connected to both ends of the rotating rod.

[0009] Preferably, the anti-reverse component includes a rotating groove, which is formed inside the dustproof shell. A ratchet disk is rotatably connected inside the rotating groove, and the ratchet disk is fixedly connected to the outer wall of the drive rod.

[0010] Preferably, the anti-reverse assembly further includes an abutment block, which is rotatably connected inside the rotating groove. A connecting ring is fixedly connected to the outer wall of the abutment block, and an adjustment groove is provided on the dustproof shell.

[0011] Preferably, the clamping assembly includes a U-shaped groove block group, which is fixedly connected to the inside of the connecting plate. A helical toothed slider is symmetrically slidably connected inside the U-shaped groove block group, and an anti-slip extrusion plate is rotatably connected to one end of the helical toothed slider away from the U-shaped groove block group.

[0012] Preferably, the clamping assembly includes a V-shaped limiting block, which is fixedly connected to one end of the helical tooth slider near the anti-slip extrusion plate. A set of return springs is symmetrically fixedly connected to the outer wall of the anti-slip extrusion plate. The end of the set of return springs away from the anti-slip extrusion plate is fixedly connected to the V-shaped limiting block. A positioning plate is fixedly connected to the side of each of the two positioning blocks near the connecting plate.

[0013] Preferably, the rack block is slidably connected inside the dustproof shell, the rotating handle is slidably connected to the outside of the dustproof shell, and the rotating rod is slidably connected inside the dustproof shell.

[0014] Preferably, a strip-shaped limiting strip is provided in the middle of the rotating rod, and the rotating rod is slidably connected to the inside of the second gear disk through the strip-shaped limiting strip. Both the first gear disk and the second gear disk mesh with the rack block, and the spiral gear threads at both ends of the rotating rod are arranged in opposite directions.

[0015] Preferably, a torsion spring is provided between the abutting block and the rotating groove so that the abutting block always abuts against the ratchet disc, and the connecting ring is slidably connected inside the adjusting groove.

[0016] Preferably, the helical tooth slider has inclined teeth, and every two helical tooth sliders form a group. Each group of helical tooth sliders has wavy anti-slip texture on the side close to the helical gear, and each helical tooth slider abuts against the helical gear close to it.

[0017] The stretching equipment for garment production based on big data technology provided by this invention has the following advantages compared with existing technologies: This equipment, through the sliding of the rotating rod and the bidirectional meshing design of the helical gear, can adaptively adapt to fabrics of different thicknesses without the need for additional clamp replacements or parameter adjustments. At the same time, the elastic deformation of the return spring assembly allows the anti-slip extrusion plate to conform to the transition slope of the fabric, avoiding damage to the fabric caused by rigid clamping and stabilizing irregularly shaped samples. This covers more types of fabric testing needs in garment production and improves the equipment's versatility in actual production scenarios.

[0018] By driving the corresponding helical tooth sliders on both sides with the helical gears respectively, the fabric is simultaneously clamped at two force points. Even if there is a difference in fabric thickness, the sliding of the rotating rod can still ensure that the anti-slip extrusion plates on both sides stably contact the fabric, so that the fabric is subjected to uniform force during the stretching process. This avoids detection errors caused by unstable clamping, ensures the authenticity and reliability of the detection data, and provides a more accurate basis for the process selection of fabrics in garment production.

[0019] Through the purely mechanical cooperation of the ratchet disc and the contact block, continuous anti-reverse rotation is achieved under the action of the torsion spring. It can maintain a stable tightening state without the need for electrical components, adapting to the complex production environment of the workshop and reducing the maintenance cost of the equipment. At the same time, through the linkage structure of the connecting ring and the adjustment groove, the anti-reverse rotation restriction can be quickly released by manual operation, and the unlocking is completed with the reverse rotation mechanism. The operation process is simple and efficient, which meets the rhythm requirements of batch inspection in garment production. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0025] Implementation, for example Figures 1 to 6 As shown, a garment production stretching device based on big data technology provided in an embodiment of the present invention includes a tensile testing machine housing 11 and a lifting device 12. The lifting device 12 is disposed on the top of the tensile testing machine housing 11, and a drive component, an anti-reverse component, and a clamping component are symmetrically arranged on the lifting device 12 and the tensile testing machine housing 11. The drive assembly includes two positioning blocks 21. One positioning block 21 is fixedly connected to the top of the tensile testing machine housing 11, and the other positioning block 21 is fixedly connected to the lifting device 12. A connecting plate 22 is fixedly connected to the outer wall of both positioning blocks 21. A dust cover 23 is fixedly connected to the side of the two connecting plates 22 away from the positioning blocks 21. A strip groove 26 is opened on the side of each connecting plate 22 near the dust cover 23. A drive rod 24 is rotatably connected inside the dust cover 23. A first gear disk 25 is fixedly connected to the middle of the drive rod 24. A rack block 27 is slidably connected inside the strip groove 26. A rotating handle 28 is fixedly connected to the outer wall of the drive rod 24.

[0026] The drive assembly also includes a rotating rod 29, which is rotatably connected inside the dust cover 23. A second gear disk 211 is slidably connected to the middle of the rotating rod 29, and helical gears 210 are symmetrically fixedly connected to both ends of the rotating rod 29.

[0027] It should be noted that: the rack block 27 is slidably connected inside the dust cover 23, and the rotating handle 28 is rotatably connected to the outside of the dust cover 23. The rotating handle 28 is rotatably connected to the outer wall of the dust cover 23 through a bearing, and its end is coaxially fixed with the end of the drive rod 24, so that it can transmit stable torque when rotating; the rotating rod 29 is slidably connected inside the dust cover 23, and the rotating rod 29 passes through the elongated sliding hole inside the dust cover 23. The length of the sliding hole matches the sliding stroke of the rotating rod 29, ensuring that the rotating rod 29 can rotate synchronously with the second gear disk 211 and also rotate along its own axial direction. Sliding; a strip-shaped limiting strip is provided in the middle of the rotating rod 29, and the rotating rod 29 is slidably connected to the inside of the second gear disk 211 through the strip-shaped limiting strip. The strip-shaped limiting strip in the middle of the rotating rod 29 is a rectangular protrusion structure, which is adapted to the rectangular groove of the inner hole of the second gear disk 211, so that the rotating rod 29 can slide along the axial direction of the second gear disk 211, and at the same time, the rotational torque of the second gear disk 211 can be synchronously transmitted to the rotating rod 29; the first gear disk 25 and the second gear disk 211 are both meshed with the rack block 27, and the threads of the helical gears 210 at both ends of the rotating rod 29 are arranged in opposite directions.

[0028] like Figures 7 to 9 As shown, the anti-reverse assembly includes a rotating groove 31, which is formed inside the dust cover 23. A ratchet disk 32 is rotatably connected inside the rotating groove 31, and the ratchet disk 32 is fixedly connected to the outer wall of the drive rod 24.

[0029] The anti-reverse assembly also includes a contact block 33, which is rotatably connected inside the rotating groove 31. A connecting ring 34 is fixedly connected to the outer wall of the contact block 33, and an adjustment groove 35 is provided on the dust cover 23.

[0030] It should be noted that: a torsion spring is sleeved at the connecting shaft between the contact block 33 and the rotating groove 31. One end of the torsion spring is fixed to the inner wall of the rotating groove 31, and the other end is fixed to the side wall of the contact block 33. The preload of the torsion spring ensures that the end of the contact block 33 is always in contact with the tooth surface of the ratchet disk 32, so that the contact block 33 is always in contact with the ratchet disk 32. The connecting ring 34 is slidably connected inside the adjusting groove 35. The outer wall of the connecting ring 34 is provided with anti-slip ridges to increase the friction between the hand and the connecting ring 34, making it easier for the operator to quickly move the connecting ring 34. Arc-shaped limiting platforms are provided at both ends of the adjusting groove 35 to limit the sliding stroke of the connecting ring 34, preventing excessive deformation of the torsion spring or excessive disengagement of the contact block 33 from the ratchet disk 32 due to excessive moving, thus ensuring the subsequent reset stability of the anti-reverse component.

[0031] like Figure 10 and Figure 11As shown, the clamping assembly includes a U-shaped groove block group 41, which is fixedly connected to the inside of the connecting plate 22. A helical tooth slider 42 is symmetrically slidably connected inside the U-shaped groove block group 41, and an anti-slip extrusion plate 43 is rotatably connected to one end of the helical tooth slider 42 away from the U-shaped groove block group 41.

[0032] The clamping assembly includes a V-shaped limiting block 44, which is fixedly connected to one end of the helical tooth slider 42 near the anti-slip extrusion plate 43. A set of return springs 45 is symmetrically fixedly connected to the outer wall of the anti-slip extrusion plate 43. The end of the set of return springs 45 away from the anti-slip extrusion plate 43 is fixedly connected to the V-shaped limiting block 44. A positioning plate 46 is fixedly connected to the side of the two positioning blocks 21 near the connecting plate 22.

[0033] It should be noted that: the helical tooth slider 42 has inclined teeth, and the inclined teeth on the helical tooth slider 42 have the same helix angle as the helical gear 210, ensuring the transmission efficiency when the two mesh; every two helical tooth sliders 42 form a group, and each group of helical tooth sliders 42 has wavy anti-slip texture on the side of the helical gear 210 that is close to it. Each helical tooth slider 42 abuts against the helical gear 210 that is close to it. The width of the helical tooth slider 42 is smaller than the width of the helical gear 210. When the helical tooth slider 42 is blocked by the fabric... When unable to move, the helical gear 210 can slide axially along the tooth surface of the helical tooth slider 42, thereby driving the rotating rod 29 to slide as a whole, so that the helical gear 210 on the other side can still maintain meshing and transmission with the corresponding helical tooth slider 42. The reset spring group 45 is composed of symmetrically distributed cylindrical springs. The two ends of the springs are welded and fixed to the anti-slip extrusion plate 43 and the V-shaped limit block 44 respectively, ensuring that the anti-slip extrusion plate 43 is subjected to uniform force, avoiding the tilting of the anti-slip extrusion plate 43 due to uneven spring force, and ensuring uniform pressure on the fabric.

[0034] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments: Working principle: During operation, the fabric to be tested is placed between the anti-slip extrusion plate 43 and the positioning plate 46. The operator rotates the handle 28, which drives the drive rod 24 to rotate synchronously. The drive rod 24 drives the first gear disk 25 on its outer wall to rotate. Since the first gear disk 25 meshes with the rack block 27, the rotation of the first gear disk 25 will drive the rack block 27 to slide along the inside of the strip groove 26. During the sliding process of the rack block 27, the rack block 27 will drive the second gear disk 211 to rotate because the second gear disk 211 meshes with the rack block 27. The second gear disk 211 will drive the rotating rod 29 to rotate synchronously through the strip-shaped limiting strip in the middle of the rotating rod 29. When the rotating rod 29 rotates, the helical gears 210 at both ends will rotate accordingly. Since the helical gears 210 mesh with the helical tooth slider 42, the helical gears 210 will drive the helical tooth slider 42 to slide along the inside of the U-shaped groove block group 41. The helical tooth slider 42 will further drive the anti-slip extrusion plate 43, the V-shaped limiting block 44, and the return spring group 45 to move towards the positioning plate 46, thus initially completing the clamping and positioning of the fabric.

[0035] When the anti-slip extrusion plate 43 comes into contact with the fabric, if the fabric has a thickness difference of "thick on one side and thin on the other": The anti-slip extrusion plate 43 on the side with thicker fabric will be blocked by the fabric first, and the corresponding helical tooth slider 42 will not be able to continue moving towards the fabric. At this time, the driving force of rotating handle 28 will still drive rotating rod 29 to rotate. Since the width of helical tooth slider 42 is smaller than the width of helical gear 210, when helical gear 210 cannot push helical tooth slider 42 on this side, it will drive rotating rod 29 to slide along the inside of dust cover 23. Because the spiral gears 210 at both ends of the rotating rod 29 have opposite thread directions, during the sliding process of the rotating rod, the spiral gear 210 on the other side can still mesh with the corresponding helical tooth slider 42, thereby driving the helical tooth slider 42 on that side to continue to move the anti-slip extrusion plate 43 towards the side of the thinner fabric, until both anti-slip extrusion plates 43 are stably in contact with the fabric, ultimately achieving adaptive fixing of fabrics of different thicknesses, ensuring that the fabric is stably clamped at both force points, and avoiding loosening of the clamping due to uneven thickness.

[0036] Adaptive fixing effect for fabrics of different thicknesses: Through the sliding of the rotating rod 29 and the bidirectional meshing design of the spiral gear 210, it can adapt to fabrics of different thicknesses without additional adjustment, solving the problem that traditional equipment cannot stably clamp irregularly shaped and thick fabrics, and improving the equipment's compatibility with different fabrics.

[0037] By utilizing the elastic deformation of the return spring assembly 45, the anti-slip extrusion plate 43 can conform to the transition slope of the fabric, which not only ensures clamping stability but also avoids hard extrusion damage to the fabric, making it suitable for more shapes of clothing fabric samples.

[0038] The principle of bonding and fixing irregularly shaped (transitional slope) fabrics: When the anti-slip extrusion plate 43 first comes into contact with the transition slope of the fabric (the interface between thick and thin areas), the slope of the fabric will exert a force on the anti-slip extrusion plate 43 in the direction of the V-shaped limiting block 44. After being pressed, the anti-slip extrusion plate 43 moves in the direction of the V-shaped limiting block 44, and at the same time, it squeezes the reset spring assembly 45 to cause it to undergo elastic deformation. The deformation of the reset spring assembly 45 will generate a reverse elastic force, pushing the anti-slip extrusion plate 43 to fit tightly against the transition slope of the fabric. This not only adapts to the irregular contour of the fabric, but also enhances the stability of the clamping through the spring force, providing a reliable fixed foundation for subsequent tensile testing.

[0039] Continue tightening steps: During the rotation of the handle 28, which drives the drive rod 24 to rotate, the drive rod 24 will simultaneously drive the ratchet disk 32 on its outer wall to rotate. Under the action of the torsion spring, the contact block 33 is always in contact with the tooth surface of the ratchet disk 32. When the drive rod 24 drives the ratchet disk 32 to rotate in the clamping and tightening direction, the contact block 33 can slide along the tooth surface of the ratchet disk 32. If the drive rod 24 tends to rotate in the opposite direction, the contact block 33 will be stuck in the tooth groove of the ratchet disk 32, restricting the ratchet disk 32 and the drive rod 24 to rotate in opposite directions, thereby achieving a continuous tightening effect during the clamping process and preventing the fabric from loosening during clamping.

[0040] Unlocking steps: When it is necessary to release the fabric, hold the connecting ring 34 and move it along the inside of the adjusting groove 35. During the movement of the connecting ring 34, it will drive the abutment block 33 to rotate away from the ratchet disk 32 until the abutment block 33 disengages from the tooth groove of the ratchet disk 32, thus releasing the rotation restriction on the ratchet disk 32. At this time, turn the rotating handle 28 in the opposite direction, and the drive rod 24 will drive the first gear disk 25 to rotate in the opposite direction. This will then drive the rotating rod 29 to rotate in the opposite direction through the rack block 27 and the second gear disk 211. The helical gear 210 will drive the helical tooth slider 42 to move away from the positioning plate 46, and the anti-slip squeezing plate 43 will separate from the fabric, completing the unlocking and removal of the fabric.

[0041] The ratchet disc 32 of the mechanical structure cooperates with the abutment block 33 to prevent loosening during the clamping process. It can maintain a continuous tightening state without electrical control, which improves the reliability of clamping. At the same time, through the linkage of the connecting ring 34 and the adjusting groove 35, the restriction of the ratchet disc 32 can be quickly released. With the help of the reverse rotation mechanism, the fabric can be quickly unlocked, which improves the operational efficiency of the inspection process.
