Description

Technical Field

[0001] This invention relates to the field of garment processing technology, specifically to a pattern-making device and its operating method for garment processing. Background Technology

[0002] Garment processing is a garment production method that mainly uses modern machine processing and supplements it with manual processing. Garments require multiple processes from fabric processing to shaping, among which garment sampling is an important part of the entire garment customization and shaping process.

[0003] Chinese patent application document 202510136895X proposes a "garment processing sampling device". This device mainly solves the problem of existing methods for removing fabric wrinkles. The main method is to lay the fabric flat on the operating table and smooth it with both hands. However, due to the small area of ​​the hands, the force is uneven, which can cause the fabric to be pulled and deformed, affecting the size of the finished garment. However, this device only relies on mechanical pressing to fix the fabric. When dealing with thin, soft or slippery fabrics, such as silk, polyester, and antistatic fabric, there is still a risk of local bulging, edge warping, or micro-displacement during the cutting process. It is difficult to achieve uniform bonding across the entire width, which affects the stability of high-precision sampling. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a pattern making device and operating method for garment processing. This invention solves the technical problem that existing pattern making devices for garment processing have a relatively simple method of pressing fabrics.

[0020] In some embodiments,

[0021] S1. Lay the garment raw material fabric to be sampled flat on the machine tool, so that it covers the multiple ventilation holes opened on the surface of the machine tool;

[0022] S2. Activate the negative pressure mechanism installed in the machine tool so that it cooperates with the ventilation hole. Through negative pressure adsorption, the fabric is stably fixed on the machine tool surface to prevent it from moving or wrinkling during subsequent operations.

[0023] S3. The fabric is clamped by the clamping mechanism. One end of the fabric is fixed by the fixed clamping part, and the movable clamping part is driven by the first driving part to move along the auxiliary tracks on both sides of the machine tool to apply tension to the other end of the fabric and clamp it, so that the fabric is taut on the machine tool.

[0025] S5. After cutting, release the clamping mechanism, turn off the negative pressure mechanism, and remove the fabric sample that has been sampled.

[0026] Compared with existing technologies, the present invention provides a garment processing sampling device and operating method. By setting multiple ventilation holes on the machine tool and forming a negative pressure adsorption area with the built-in negative pressure mechanism, the fabric can be evenly and tightly adsorbed onto the entire worktable after being laid out. Compared with the traditional method of relying only on edge clamping or local pressure plates, it effectively avoids bulging in the middle of the fabric, edge curling, or micro-displacement caused by vibration / traction during the cutting process. It is especially suitable for lightweight, high-elasticity, or easily slipping fabrics, such as chiffon, spandex blends, and antistatic fabrics, significantly improving the geometric accuracy and dimensional consistency of the sampling outline. The clamping mechanism includes movable clamping parts and fixed clamping parts, and the movable end is driven by the first driving part to move along the auxiliary track, which can apply controllable tension in the length direction of the fabric. At the same time, the negative pressure mechanism provides vertical adsorption force on the entire area of ​​the fabric. The two work together to ensure that the fabric is appropriately straightened in the longitudinal direction and slack is eliminated, and also in the transverse direction. The middle section achieves wrinkle-free bonding, resolving the technical contradictions of single clamping leading to localized stretching deformation and single adsorption making it difficult to control overall tension. The cutting end of the cutting mechanism is positioned between the movable and fixed clamping parts and is driven by a second drive unit to move along the length of the machine tool, ensuring that the cutting path is always within the area where the fabric is effectively constrained. With the assistance of negative pressure adsorption, even if the cutting end runs at high speed or encounters fabric seams or thickness changes, the fabric will not jump or shift due to the reaction force, thus ensuring a straight cut without burrs. At the same time, it expands the device's adaptability to processing multi-layer fabrics or composite materials. The guide roller is set at one end of the machine tool, which initially flattens and guides the fabric during the fabric feeding stage, reducing initial wrinkles. Subsequently, the negative pressure mechanism immediately adsorbs and locks the flat state output by the guide roller onto the table, avoiding secondary disturbances caused by manual material laying. This achieves continuous and automated flatness control from feeding to fixing, laying the foundation for high-efficiency sampling. Attached Figure Description

[0035] 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 illustrative and not intended to limit the invention.

[0036] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a garment processing sampling device according to an embodiment of the present invention. A garment processing sampling device includes:

[0037] The machine tool 1 has auxiliary rails 11 on both sides and multiple ventilation holes 12 on the machine tool 1.

[0038] Guide roller 2 is installed at one end of machine tool 1;

[0039] The clamping mechanism 3 includes a movable clamping member 31, a fixed clamping member 32 and a first driving member 33. The movable clamping member 31 is slidably connected to the auxiliary rail 11 and is driven by the first driving member 33. The fixed clamping member 32 is provided at the end of the machine tool 1.

[0040] The cutting mechanism 4 includes a cutting end 44 and a second driving member 45. The cutting end 44 is disposed between the movable clamping member 31 and the fixed clamping member 32, and the cutting end 44 is connected to the second driving member 45. The second driving member 45 is used to drive the cutting end 44 to move along the length direction of the machine tool 1.

[0041] The negative pressure mechanism 5 is installed inside the machine tool 1 and is used to cooperate with the vent hole 12 to adsorb raw materials.

[0042] In this embodiment, by setting multiple ventilation holes 12 on the machine tool 1 and forming a negative pressure adsorption area with the built-in negative pressure mechanism 5, the fabric can be evenly and tightly adsorbed onto the entire worktable after being laid out. Compared with the traditional method of relying solely on edge clamping or local pressure plates, this effectively avoids bulging in the middle of the fabric, edge lifting, or micro-displacement caused by vibration / traction during the cutting process. It is especially suitable for lightweight, highly elastic, or easily slipping fabrics, such as chiffon, spandex blends, and antistatic fabrics, significantly improving the geometric accuracy and dimensional consistency of the sample outline. The clamping mechanism 3 includes a movable clamping part 31 and a fixed clamping part 32, and the movable end is driven by the first driving part 33 to move along the auxiliary track 11, which can apply controllable tension in the length direction of the fabric. At the same time, the negative pressure mechanism 5 provides vertical adsorption force to the entire fabric width. The two work together to ensure that the fabric is appropriately straightened in the longitudinal direction and slack is eliminated, while achieving wrinkle-free bonding in the transverse direction and the middle, solving the problem of single The technical contradiction of clamping easily leading to localized stretching deformation and single adsorption making it difficult to control overall tension is addressed by the cutting end 44 of the cutting mechanism 4, which is positioned between the movable clamping member 31 and the fixed clamping member 32 and is driven by the second driving member 45 to move along the length of the machine tool 1. This ensures that the cutting path is always within the area where the fabric is effectively constrained. With the assistance of negative pressure adsorption, even if the cutting end 44 runs at high speed or encounters fabric seams or thickness changes, the fabric will not jump or shift due to the reaction force, thus ensuring a straight cut without burrs. At the same time, it expands the device's adaptability to processing multi-layer fabrics or composite materials. The guide roller 2 is positioned at one end of the machine tool 1 and performs preliminary flattening and guidance on the fabric during the fabric feeding stage, reducing initial wrinkles. Subsequently, the negative pressure mechanism 5 immediately adsorbs and "locks" the flat state output by the guide roller 2 onto the table, avoiding secondary disturbances caused by manual material laying. This achieves continuous and automated flattening control from feeding to fixing, laying the foundation for high-efficiency sampling.

[0043] In one embodiment, please refer to Figure 1 - Figure 5To improve the movement efficiency of the movable clamping member 31 and the cutting mechanism 4, the auxiliary track 11 includes a first slide rail 111, a second slide rail 112, and a first toothed plate 113. The first slide rail 111 and the second slide rail 112 are respectively provided on both sides of the machine tool 1. The first toothed plate 113 is connected to the lower end of the machine tool 1. The movable clamping member 31 and the cutting mechanism 4 are slidably connected to both the first slide rail 111 and the second slide rail 112. The output end of the first driving member 33 meshes with the first toothed plate 113. The movable clamping member 31 includes a first frame 311, a first hydraulic rod 312, and a first clamping plate 313. The first frame 311 is slidably connected to the first slide rail 111 and the second slide rail 112, and the first hydraulic rod 312 is connected to the first frame 311. The telescopic end is connected to a first clamping plate 313, which is located above the machine tool 1. The first driving component 33 includes a first motor 331 and a first gear 332. The first motor 331 is installed on the outside of the first frame 311, and the output end of the first motor 331 is connected to the first gear 332. The first gear 332 meshes with the first toothed plate 113. The cutting mechanism 4 includes a second frame 41, a second toothed plate 42, and a height adjusting component 43. The second frame 41 is slidably connected to the first slide rail 111 and the second slide rail 112, and a through hole 411 is provided on the second frame 41. The second toothed plate 42 is fixed at the upper end of the second frame 41. The height adjusting component 43 is slidably connected in the through hole 411, and the telescopic end of the height adjusting component 43 is connected to the cutting end 44.

[0044] In this embodiment, a first slide rail 111 and a second slide rail 112 are respectively provided on both sides of the machine tool 1. The movable clamping member 31 and the frame of the cutting mechanism 4 are connected across the two slide rails, which improves the lateral rigidity and torsional resistance of the moving parts and effectively prevents shaking, skewing or jamming when moving at high speed or under uneven force. At the same time, the first toothed plate 113 is fixed to the lower end of the machine tool 1 and meshes with the first gear 332 installed on the first frame 311, driven by the first motor 331. This ensures that the movable clamping member 31 achieves precise, stable and controllable linear movement along the length of the machine tool 1, laying the foundation for fabric tensioning and cutting path control. After clamping, the cutting mechanism 4 can move freely to any cutting position for operation. The two do not interfere with each other and can cooperate in an orderly manner according to the process flow, greatly improving the automation level and work efficiency of the sampling process. The movable clamping member 31 drives the first clamping plate 313 to move up and down through the first hydraulic rod 312 to achieve flexible clamping of the fabric. The hydraulic structure can precisely adjust the clamping force to avoid indentation or damage to delicate fabrics such as silk and lace, while ensuring sufficient clamping force for heavy fabrics such as denim and canvas. After the clamping action is completed, the entire first frame 311 can still be driven by the first motor 331 to move along the slide rail, realizing a composite operation of clamping and then tensioning, effectively eliminating fabric slack and improving the flatness of the sampling reference surface. The second frame 41 of the cutting mechanism 4 is provided with a through hole 411, in which the height adjustment component 43 is slidably installed. Its telescopic end is connected to the cutting end 44, so that the cutting slice 442 can dynamically adjust the downward pressure and cutting depth according to the fabric thickness, number of layers or material hardness. At the same time, the second frame 41 itself can move along the slide rail, and with the height adjustment, it forms a two-dimensional control capability of X-axis movement and Z-axis height adjustment, ensuring that the cutting end 44 is always perpendicular to the fabric surface, with neat cuts and no dragging. It is especially suitable for multi-layer sampling, irregular contours or composite cutting scenarios with lining.

[0045] In one embodiment, please refer to Figure 1 - Figure 3 To improve the working efficiency of the guide roller 2, the guide roller 2 includes a first roller 21 and a second roller 22. The first roller 21 and the second roller 22 are rotatably connected to one side of the upper end of the machine tool 1, and a gap is maintained between the first roller 21 and the second roller 22.

[0046] In this embodiment, the first roller 21 and the second roller 22 are arranged in parallel with an appropriate gap, forming a double-roller clamping guide channel. When the fabric enters the gap from the unwinding device or the manual feeding end, the two rollers rotate synchronously under the tension of the fabric or a slight driving action, applying a uniform lateral flattening force and longitudinal traction force to the fabric. This process can effectively eliminate the initial wrinkles, ripples, or local slack caused by the fabric during the conveying process due to winding, folding, or handling, providing a flat initial state for subsequent precise positioning and cutting on the machine tool 1. Since the first roller 21 and the second roller 22 are symmetrically arranged and the gap is adjustable, the fabric is constrained by the roller surfaces on both sides when passing through the gap, effectively preventing lateral deviation, twisting, or edge curling in the width direction. This mechanical guiding effect significantly improves the consistency of the fabric feeding trajectory and the repeatability of positioning accuracy, and is especially suitable for wide fabrics or multi-layer stacked sampling sites. In traditional sampling operations, operators need to manually flatten the fabric and visually align it, which is inefficient and inconsistent. This application, by setting up a double-roller guide structure, achieves automatic guidance, automatic flattening, and automatic traction during the fabric feeding stage, greatly reducing manual smoothing and alignment operations. This not only improves work efficiency but also reduces sampling errors caused by human error, providing a reliable basis for the subsequent fully automated cutting process. The first roller 21 and the second roller 22 are both rotatably connected, meaning they can rotate as the fabric passes through, avoiding sliding friction with the fabric surface. Compared with fixed guide plates or sharp-angle guide structures, this significantly reduces the frictional resistance between the fabric and the guide components, effectively preventing scratches, pilling, static electricity accumulation, or surface indentations on thin, high-gloss, or functional fabrics, such as antistatic fabrics, coated fabrics, and silk, during the feeding process, ensuring the appearance quality and functional integrity of the sample.

[0047] In one embodiment, please refer to Figure 1 - Figure 7To improve the working efficiency of the cutting device, the fixed clamping component 32 includes two fixed frames 321, a spring damper 322, a column 323, a second hydraulic rod 324, and a second clamping plate 325. The fixed frames 321 are fixed on the machine tool 1 and away from the guide roller 2. The spring damper 322 is provided on the two fixed frames 321, and one end of the spring damper 322 is connected to the second clamping plate 325. The column 323 is provided between the two fixed clamping plates, and the second hydraulic rod 324 is connected to the column 323. The second clamping plate 325 is connected to the telescopic end of the second hydraulic rod 324, and the second clamping plate 325 is slidably connected to the column 323. The height adjustment component 43 includes a first electric telescopic rod 431 and a support plate 432. The support plate 432 is slidably connected to the through hole 411, and the first electric telescopic rod 431 is fixed to the lower end of the support plate 432. The telescopic end of the first electric telescopic rod 431 is connected to a cutting end 44. A second driving component 45 is fixed to the upper end of the support plate 432. The second driving component 45 meshes with a second toothed plate 42. The second driving component 45 includes a drive motor 451 and a drive gear 452. The drive motor 451 is mounted on the support plate 432, and the output end of the drive motor 451 is connected to the drive gear 452. The drive gear 452 meshes with the second toothed plate. 42 engagement, the cutting end 44 includes a cutting motor 441 and a cutting blade 442, the cutting motor 441 is installed at the lower end of the support plate 432, and the output end of the cutting motor 441 is connected to the cutting blade 442, the negative pressure mechanism 5 includes a housing 51, a wind force regulating component 52, a filter screen 53 and an adsorption component 54, the housing 51 is connected to the lower end of the machine tool 1, and the wind force regulating component 52 includes several second electric telescopic rods 521, a baffle plate 522 and a spring strip 524, the several second electric telescopic rods 521 are installed in the housing 51, and the baffle plate 522 is connected to the second electric telescopic rods 521, the baffle plate 522 is slidably connected to the support plate 432. Inside the housing 51, a second ventilation hole 523 is provided on its surface to cooperate with the first ventilation hole 12. A spring strip 524 is connected to one end of the baffle plate 522 away from the second electric telescopic rod 521. A filter screen 53 is provided at the lower end of the baffle plate 522. The adsorption component 54 includes several diversion pipes 541, a conduit 542 and a pump body 545. Several diversion pipes 541 are equidistantly arranged at the lower end of the filter screen 53, and an adsorption head 5411 is provided on any one of the diversion pipes 541. Several diversion pipes 541 are connected to the conduit 542. The end of the conduit 542 is connected to the pump body 545, and the end of the pump body 545 is connected to the external dust collection box.

[0048] In this embodiment, the second clamping plate 325 is connected to the fixed frame 321 via a spring damper 322, forming a clamping structure with buffering capability. When the second hydraulic rod 324 pushes the second clamping plate 325 down to press the fabric, the spring damper 322 can absorb overload impact, preventing rigid clamping from causing indentations, deformation, or fiber breakage on delicate fabrics such as silk, lace, and functional coated fabrics. Different fabrics or layers have different thicknesses, and the spring damper 322 allows the second clamping plate 325 to float slightly in the vertical direction, automatically adapting to changes in fabric thickness to ensure effective clamping under various working conditions. This prevents the fabric from slipping during cutting due to insufficient clamping force. 325 is slidably connected to column 323 and is driven vertically by second hydraulic rod 324. This structure ensures precise and unbiased movement of the clamping plate, preventing fabric twisting caused by lateral forces. Simultaneously, the hydraulic system precisely controls the clamping force, balancing clamping strength and fabric protection. The first electric telescopic rod 431, acting as a height adjuster 43, can adjust the distance between the cutting end 44 and the machine tool surface in real time, precisely matching the sampling requirements of single-layer, multi-layer, or lining fabric samples to ensure the cutting depth is just right. The drive motor 451 mounted on the upper end of support plate 432 drives drive gear 452, which meshes with the second toothed plate 42 fixed on the second frame 41, ensuring the cutting depth is optimal. End 44 smoothly and accurately tracks complex patterning contours along the length of machine tool 1, especially suitable for fine cutting paths such as curves and concave areas. The second ventilation hole 523 on the baffle plate 522 corresponds to the first ventilation hole 12 on machine tool 1. The position of the baffle plate 522 can be adjusted by the second electric telescopic rod 521, and the overlapping area of ​​the two can be dynamically controlled, thereby adjusting the adsorption intensity in different areas. For example, the negative pressure can be increased in the cutting area and the adsorption can be weakened in the non-working area, which saves energy and avoids the fabric from being stretched and deformed due to strong adsorption throughout the entire area. One end of the baffle plate 522 is actively driven by the electric telescopic rod, and the other end is provided with a spring strip 524 to ensure reliable reset when the power is off or the command ends, preventing... To prevent the mechanism from jamming and improve system reliability, the adsorption airflow is initially intercepted by the filter screen 53, and then the negative pressure is evenly distributed through the array of diversion pipes 541. Finally, it is introduced into the external dust collection box by the pump body 545, which effectively prevents dust from entering the pump body 545 or clogging the air vents, thus extending the equipment life and keeping the working environment clean, which meets the environmental protection and occupational health requirements of modern garment workshops. Multiple diversion pipes 541 are arranged at equal intervals, and each diversion pipe 541 is equipped with an adsorption head 5411 to form a gridded negative pressure field, so that the fabric is subjected to uniform force throughout the entire width, completely eliminating the problems of center depression and edge curling caused by traditional single-point suction, and providing an ideal flat reference surface for high-precision sampling.

[0049] To better understand this invention, the following is combined with... Figures 1 to 7 The technical solution of the present invention will be described in detail below:

[0050] S1. The fabric to be sampled is introduced from the unwinding device or the manual feeding end, so that it passes through the gap of the guide roller 2, that is, the double roller channel formed by the first roller 21 and the second roller 22. The two rollers rotate synchronously under the action of the fabric tension, applying a lateral flattening force and a longitudinal traction force to the fabric, automatically eliminating the initial wrinkles, ripples or edge curling caused by winding, folding or handling; at the same time, the limiting function of the rollers prevents the fabric from shifting in the width direction, ensuring that it is laid flat and symmetrically on the surface of the machine tool 1, and covering all the ventilation holes 12 area;

[0051] S2. Start the negative pressure mechanism 5, and the pump body 545 works. A negative pressure is formed above the filter screen 53 through the diversion pipe 541 and the adsorption head 5411. The airflow is drawn upward through the vent hole 12, so that the fabric is evenly and tightly adsorbed onto the surface of the machine tool 1, achieving full-area bonding and preventing bulging in the middle or lifting at the edges. At the same time, the fixed clamping part 32 is activated, and the second hydraulic rod 324 pushes the second clamping plate 325 to move down along the column 323. After being buffered by the spring damper 322, it presses the end of the fabric away from the guide roller 2, completing the initial fixing of the boundary. This clamping is adaptive and can be compatible with fabrics of different thicknesses, avoiding damage to delicate fabrics.

[0052] S3. The first motor 331 starts, driving the first gear 332 to roll along the first toothed plate 113, driving the first frame 311 to move away from the fixed clamping member 32 along the first slide rail 111 and the second slide rail 112, so that the fabric is moderately stretched in the length direction. When the preset tension is reached, the first hydraulic rod 312 is activated, driving the first clamping plate 313 to press down, clamping the end of the fabric near the guide roller 2 above the machine tool 1. At this point, the fabric, under longitudinal tension, with the vertical adsorption force applied by the movable clamping member 31 and the fixed clamping member 32, and the dual action provided by the negative pressure mechanism 5, achieves the ideal sampling state of being taut without looseness and close without wrinkles.

[0053] S4. Drive motor 451 starts, and drive gear 452 at its output end meshes with second tooth plate 42, driving support plate 432 and the entire cutting mechanism 4 to move along auxiliary track 11 in the area between movable clamping member 31 and fixed clamping member 32. At the same time, first electric telescopic rod 431 adjusts the height of cutting end 44 in real time according to fabric thickness, so that cutting slice 442 accurately cuts into fabric surface. Cutting motor 441 rotates at high speed to drive cutting slice 442 to cut along preset sampling contour. During this process, negative pressure adsorption continues to work to ensure that even when cutting at high speed, passing seams or processing multiple layers of fabric, the fabric does not jump, shift or drag, and the cut is straight and without rough edges.

[0054] S5. After cutting is completed, the cutting motor 441 and the drive motor 451 are turned off in sequence to stop the movement of the cutting mechanism 4; the first hydraulic rod 312 and the second hydraulic rod 324 retract, releasing the first clamping plate 313 and the second clamping plate 325, and releasing the mechanical clamping; the pump body 545 is turned off to stop the negative pressure adsorption, and the fabric sample that has been sampled is removed. The second electric telescopic rod 521 returns to its original position, driving the baffle plate 522 to reset. With the assistance of the spring strip 524, the adsorption area is closed. The fiber dust generated during the adsorption process is intercepted by the filter screen 53, and the debris is introduced into the external dust collection box through the pump body 545 for easy cleaning and maintenance. The system returns to the initial state and is ready for the next round of sampling.

Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
