Description

Technical Field

[0001] This utility model relates to the field of cutting and positioning technology, and in particular to an adjustable positioning device for clothing cutting. Background Technology

[0002] Positioning devices for garment cutting are key auxiliary equipment in the garment cutting process. Their core function is to ensure cutting accuracy and work efficiency. They can help calibrate the warp and weft of the fabric, ensure that the grain direction of the cut pieces meets the design requirements, reduce pattern deviation, and in batch cutting, standardize the size of the cut pieces, reduce errors in manual positioning, shorten cutting preparation time, and provide neat and consistent cut pieces for subsequent sewing. They are an important tool for achieving standardization in garment production and improving the quality of finished products.

[0003] Positioning devices for garment cutting can significantly improve the quality and efficiency of cutting operations, ensure uniform size of cut pieces in the same batch, reduce the instability of manual positioning, adapt to a variety of fabrics, have strong applicability, assist in calibrating the warp and weft of the fabric, ensure that the threads of the cut pieces meet the design requirements, reduce pattern problems in subsequent sewing processes, and shorten cutting preparation time, reduce the intensity of manual operation, help standardize garment production, and provide strong support for improving finished product quality and reducing rework rates.

[0004] When garments are placed directly on the workbench or held in place by hand during cutting, the fabric will shift and wrinkle during the cutting process. This is especially true for lightweight fabrics such as silk, chiffon, or elastic knitted fabrics, which can lead to uneven edges, size deviations, and inconsistencies in the same batch of fabrics. This affects the accuracy of subsequent sewing and splicing. In addition, manual adjustment and pressing of the fabric not only increases operation time and reduces cutting efficiency, but also leaves stains or wrinkles due to frequent hand contact, further affecting the quality of the fabrics and increasing rework costs.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-2 An embodiment of this utility model is provided: an adjustable positioning device for clothing cutting, including a support base frame 1 and a cantilever base plate 2. Multiple fabric fixing mechanisms 3 are provided around the top of the support base frame 1. The fabric fixing mechanisms 3 are used to fix the fabric to be cut. A cantilever opening mechanism 4 is provided on the top of the cantilever base plate 2. The cantilever opening mechanism 4 is used to lift and lower the cutting equipment. A cantilever moving mechanism 5 is provided on the top of the support base frame 1.

[0035] The fabric fixing mechanism 3 includes multiple bases 31. The bottom of the multiple bases 31 is fixedly connected to the top of the support base 1 around the perimeter. Two pins 32 are rotatably connected to the front and rear sides of the top of the multiple bases 31. A transmission rod 33 is rotatably connected to the top of the inner wall of the front pin 32. The rear side of the transmission rod 33 is rotatably connected to the top of the inner wall of the rear pin 32. A pressure rod 34 is fixedly connected to the front side of the front pin 32. Two pressure plates 35 are fixedly connected to the bottom of the multiple pressure rods 34. An execution component 36 is provided at the bottom of the front side of the transmission rod 33.

[0036] Specifically, when fixing the fabric to be cut, the fabric is first laid flat on top of the support base 1. At this time, the fabric fixing mechanism 3 begins to perform the fixing action. Multiple bases 31 in the fabric fixing mechanism 3 are fixedly connected to the top of the support base 1, providing stable support for the entire fabric fixing mechanism 3. When it is necessary to fix the fabric, the driving actuator 36 is used to drive the actuator 36 to apply the power generated by the actuator 36 to the bottom front side of the transmission rod 33. Since the front side of the transmission rod 33 is rotatably connected to the top of the inner wall of the front pin 32, and the rear side of the transmission rod 33 is rotatably connected to the top of the inner wall of the rear pin 32, the driving force of the actuator 36 will drive the transmission rod 33 to move forward. When the transmission rod 33 rotates, it will drive the front pin 32 and the rear pin 32 to rotate around their connection point with the base 31. The front pin 32 is fixedly connected to the front side of the pressure rod 34. The rotation of the front pin 32 will synchronously drive the pressure rod 34 to rotate downward. The bottom of the pressure rod 34 is fixedly connected to two pressure plates 35. As the pressure rod 34 rotates downward, the pressure plates 35 will gradually approach and finally press the fabric to be cut flat on the top of the support base 1. The actuator 36 provides power, the transmission rod 33 transmits power, and the pin 32 drives the pressure rod 34 to rotate, thus achieving the fixing effect of the pressure plate 35 on the fabric to be cut, ensuring that the fabric will not shift during the cutting process.

[0037] After the fabric is fixed, when it is necessary to adjust the position and height of the cutting equipment, it can be operated through the cantilever moving mechanism 5 and the cantilever opening mechanism 4. The cantilever moving mechanism 5 is set on the top of the support base 1. Driven by the cantilever moving mechanism 5, the cantilever base plate 2 can be moved horizontally along the top of the support base 1, which in turn drives the cantilever opening mechanism 4 set on the top of the cantilever base plate 2 to move synchronously. When the cantilever opening mechanism 4 moves to the required cutting position, the cantilever opening mechanism 4 can drive the cutting equipment to perform lifting and lowering movements, adjusting the distance between the cutting equipment and the fabric to be cut, so that the cutting equipment reaches the appropriate cutting height.

[0038] Reference Figures 3-4The cantilever opening mechanism 4 includes a second cylinder 41. The bottom of the second cylinder 41 is fixedly connected to the top of the cantilever base plate 2. A lifting plate 42 is fixedly connected to the top of the second cylinder 41. Sliding columns 43 are fixedly connected to the left and right sides of the top of the cantilever base plate 2. A fixing frame 44 is fixedly connected to the rear side of the cantilever base plate 2. Lifting frame assemblies 45 are provided on the outer walls of the two sliding columns 43. A cutting assembly 46 is fixedly connected to the front side of the sliding column 43.

[0039] Specifically, when the height of the cutting equipment needs to be adjusted via the cantilever opening mechanism 4, cylinder 2 41 is first activated. The bottom of cylinder 2 41 is fixedly connected to the top of the cantilever base plate 2. After cylinder 2 41 is activated, it generates a vertical driving force. This driving force acts on the lifting plate 42 fixedly connected to the top of cylinder 2 41, causing the lifting plate 42 to move vertically. At the same time, sliding columns 43 are fixedly connected to the left and right sides of the top of the cantilever base plate 2. Lifting frame assemblies 45 are provided on the outer walls of the two sliding columns 43. The movement of the lifting plate 42 will synchronously drive the lifting frame assemblies. 45 slides vertically along the outer wall of the sliding column 43 to ensure the stability of the lifting process. The rear side of the cantilever base plate 2 is fixedly connected to the fixing frame 44. The fixing frame 44 provides the installation and positioning base for the components of the entire cantilever opening mechanism 4, and avoids the components from shifting position during the movement. The cylinder 41 provides vertical driving force, and the lifting plate 42 transmits power and drives the lifting frame assembly 45 to slide along the sliding column 43, so as to achieve the effect of stable vertical movement of the lifting frame assembly 45, laying the foundation for the subsequent height adjustment of the cutting assembly 46.

[0040] Once the lifting frame assembly 45 has moved to the required height, the cutting assembly 46 can perform the cutting action. The cutting assembly 46 is fixedly connected to the front side of the sliding column 43. After the height of the lifting frame assembly 45 is positioned, the cutting assembly 46 will be in a cutting position that matches the fabric to be cut. At this time, the cutting assembly 46 is activated and, under the positioning support of the lifting frame assembly 45, performs the cutting operation on the fabric to be cut, which is laid flat and fixed to the top of the support base 1. During the cutting process, the sliding column 43 not only provides sliding guidance for the lifting frame assembly 45, but also provides stable installation support for the cutting assembly 46, ensuring that the cutting assembly 46 remains stable during the cutting process.

[0041] Reference Figures 2-4The execution component 36 includes a rotating shaft 362, which is rotatably connected to the front side of the transmission rod 33. The bottom of the rotating shaft 362 is fixedly connected to the output end of the cylinder 361. The lifting frame assembly 45 includes two outer frames 451, the inner walls of the two outer frames 451 are slidably connected to the outer wall of the slide column 43, and rotating columns 452 are rotatably connected to the inner walls of the two outer frames 451. The cutting component 46 includes a buffer frame 461, the rear side of the buffer frame 461 is fixedly connected to the front side of the outer frame 451, the top of the buffer frame 461 is fixedly connected to a reversing motor 462, and the output end of the reversing motor 462 is fixedly connected to a cutting blade 463.

[0042] Specifically, when it is necessary to fix the fabric to be cut, the execution component 36 starts to operate. After the cylinder 361 in the execution component 36 is started, it generates driving force. The driving force acts on the rotating shaft 362 fixedly connected to the output end of the cylinder 361, causing the rotating shaft 362 to rotate. Since the internal rotation of the rotating shaft 362 is connected to the front side of the transmission rod 33, the rotation of the rotating shaft 362 will synchronously drive the transmission rod 33 to rotate. The rotation of the transmission rod 33 further drives the front pin 32 and the rear pin 32 connected to it to rotate, thereby causing the pressure rod 34 fixed on the front pin 32 to flip downward, and finally causing the pressure plate 35 at the bottom of the pressure rod 34 to press the fabric. Through the driving force provided by the cylinder 361 and the power transmitted by the rotating shaft 362 to drive the transmission rod 33 to rotate, the execution component 36 drives the fabric fixing mechanism 3 to complete the fabric fixing effect, preparing for subsequent cutting.

[0043] During the cutting operation, the lifting frame assembly 45 first adjusts its height. The inner walls of the two outer frames 451 in the lifting frame assembly 45 are slidably connected to the outer wall of the slide column 43. When the cylinder 41 drives the lifting plate 42 to move, the lifting plate 42 will push the two outer frames 451 to slide vertically along the outer wall of the slide column 43. At the same time, the rotating column 452, which is rotatably connected around the inner walls of the two outer frames 451, will rotate accordingly to reduce the friction between the outer frames 451 and the slide column 43. By sliding the outer frames 451 along the slide column 43 and reducing friction with the assistance of the rotating column 452, the lifting frame assembly 45 achieves a stable and smooth lifting effect, ensuring that the cutting assembly 46 can reach the appropriate cutting height.

[0044] Once the lifting frame assembly 45 is in place, the cutting assembly 46 begins operation. The rear side of the buffer frame 461 in the cutting assembly 46 is fixedly connected to the front side of the outer frame 451 and is positioned together with the outer frame 451. After the reversing motor 462 fixedly connected to the top of the buffer frame 461 is started, its output end will drive the fixedly connected cutting blade 463 to rotate. The cutting blade 463 cuts the fabric to be cut under the drive of the reversing motor 462. With the buffer frame 461 providing installation support and the reversing motor 462 driving the cutting blade 463 to rotate, the cutting assembly 46 achieves the effect of accurately cutting the fabric to be cut, thus completing the cutting operation.

[0045] Reference Figures 5-6 The cantilever moving mechanism 5 includes two platforms 51, the bottoms of which are both located on the top of the supporting base 1. Two threaded rods 52 pass through adjacent platforms 51. Bearings 53 are fixedly connected to the left and right outer walls of the two threaded rods 52. The outer walls of the bearings 53 are fixedly connected to the interior of the platforms 51. A power assembly 54 is located on the top of the platforms 51. Embedded slide rail assemblies 55 are located on the left and right sides of the top of the supporting base 1. The power assembly 54 includes a motor 541, the bottom of which is fixedly connected to the top of the platforms 51. A gear is fixedly connected to the output end of the motor 541. Gear 1 542 is meshed with gear 2 543 on both the front and rear sides. Threaded rod 1 52 is fixedly connected inside each of the two gear 2 543. The embedded slide assembly 55 includes two slide housings 551. The bottoms of the two slide housings 551 are fixedly connected to the top left and right sides of the support base 1, respectively. Motor 2 552 is fixedly connected to the rear side of each of the two slide housings 551. Threaded rod 2 553 is fixedly connected to the output ends of each of the two motor 2 552. Slide table 554 is threadedly connected to the outer surface of each of the two threaded rod 2 553. The tops of the two slide tables 554 are fixedly connected to the bottoms of the two platforms 51, respectively.

[0046] Specifically, when the cantilever moving mechanism 5 needs to be adjusted laterally, the power assembly 54 is activated first. The bottom of motor 541 in the power assembly 54 is fixedly connected to the top of the platform 51. After motor 541 starts, it generates rotational power, which is transmitted to gear 542 fixedly connected to the output end of motor 541, causing gear 542 to rotate. Since gear 542 is meshed with gears 543 on both its front and rear sides, the rotation of gear 542 synchronously drives the two gears 543 to rotate. Each of the two gears 543 has a threaded rod fixedly connected inside. 52, and two threaded rods 52 pass through the two adjacent stages 51. At the same time, the outer walls of the bearings 53, which are fixedly connected to the left and right outer walls of the threaded rods 52, are fixed inside the stages 51. The rotation of the gear 543 will drive the threaded rods 52 to rotate under the support of the bearings 53, thereby pushing the two stages 51 to move relative to or towards each other along the axial direction of the threaded rods 52. The motor 541 provides rotational power, the gear set transmits power and drives the threaded rods 52 to rotate, thus realizing the effect of the power component 54 driving the stages 51 to move laterally, laying the foundation for subsequent overall position adjustment;

[0047] When the cantilever moving mechanism 5 needs to be adjusted longitudinally, the embedded slide rail assembly 55 starts to operate. The bottoms of the two slide rail housings 551 in the embedded slide rail assembly 55 are fixedly connected to the top left and right sides of the support base 1, respectively. After the motor 552 fixedly connected to the rear side of the slide rail housing 551 starts, it generates rotational power. The power is transmitted to the threaded rod 553 fixedly connected to the output end of the motor 552, which drives the threaded rod 553 to rotate inside the slide rail housing 551. Since the threaded rod 553 is threadedly connected to the slide table 554, and the top of the slide table 554 is fixedly connected to the bottom of the stage 51, the rotation of the threaded rod 553 will drive the slide table 554 to slide along the axial direction of the threaded rod 553, thereby moving the stage 51 and the components connected above it along the length of the slide rail housing 551. Through the rotational power provided by the motor 552 and the threaded transmission between the threaded rod 553 and the slide table 554, the embedded slide rail assembly 55 achieves the effect of driving the stage 51 to move longitudinally.

[0048] Working Principle: First, the fabric to be cut is fixed. The operator lays the fabric flat on the top of the support frame 1, ensuring that the fabric covers the cutting area evenly. At this time, the fabric fixing mechanism 3 starts and performs the fixing action. Multiple bases 31 in the fabric fixing mechanism 3 are fixedly connected to the top of the support frame 1, providing a stable installation support base for the entire fabric fixing mechanism 3 and preventing the position of the components from shifting during subsequent fixing actions. When it is necessary to fix the fabric, the actuator 36 is driven. After the cylinder 361 in the actuator 36 starts, it generates driving force. The driving force acts on the rotating shaft 362 fixedly connected to the output end of the cylinder 361, causing the rotating shaft 362 to rotate. Since the internal rotating connection of the rotating shaft 362 is to the front side of the transmission rod 33, the rotation of the rotating shaft 362 will synchronously drive the transmission rod 33 to rotate; and since the front side of the transmission rod 33 is rotatably connected to the inner wall of the front pin 32... The top of the transmission rod 33 is rotatably connected to the top of the inner wall of the rear pin 32. Therefore, the rotation of the transmission rod 33 will drive the front pin 32 and the rear pin 32 to rotate around their connection point with the base 31. The front side of the front pin 32 is fixedly connected to the pressure rod 34. The rotation of the front pin 32 will synchronously drive the pressure rod 34 to rotate downward. The bottom of the pressure rod 34 is fixedly connected to two pressure plates 35. As the pressure rod 34 rotates downward, the pressure plates 35 will gradually approach the fabric to be cut that is laid flat on the top of the support frame 1, and finally press the fabric. The cylinder 361 in the actuator 36 provides driving force, and the rotating shaft 362 transmits power to drive the transmission rod 33 to rotate. Then the transmission rod 33 drives the pin 32 to rotate, causing the pressure rod 34 to rotate. This achieves the fixing effect of the pressure plate 35 on the fabric to be cut, ensuring that the fabric will not shift during the subsequent cutting process, and providing a stable fabric base for the cutting operation.

[0049] After the fabric is fixed, the cutting position adjustment stage begins. The cantilever moving mechanism 5 moves the cantilever base plate 2 and the cantilever opening mechanism 4 and cutting assembly 46 above it to the required cutting position. The cantilever moving mechanism 5 is located on the top of the support base 1. Its adjustment process is divided into two parts: horizontal adjustment and vertical adjustment. During horizontal adjustment, the power assembly 54 is started first. The bottom of the motor 541 in the power assembly 54 is fixedly connected to the top of the platform 51. After the motor 541 is started, it generates rotational power, which is transmitted to the gear 5 fixedly connected to the output end of the motor 541. 42. This drives gear 542 to rotate. Since gear 542 is meshed with gear 543 on both its front and rear sides, the rotation of gear 542 synchronously drives the rotation of both gear 543. Each of the two gear 543 has a threaded rod 52 fixedly connected inside, and the two threaded rods 52 pass through the adjacent spaces between the two stages 51. Simultaneously, the outer walls of bearings 53, fixedly connected to the left and right outer walls of the threaded rods 52, are fixed inside the stages 51. The rotation of gear 543 drives the threaded rods 52 to rotate under the support of the bearings 53, thereby pushing the two stages 51 along the threaded... The axial movement of rod 52 relative to or towards each other completes the lateral position adjustment. During longitudinal adjustment, the embedded slide assembly 55 begins to operate. The bottoms of the two slide housings 551 in the embedded slide assembly 55 are respectively fixedly connected to the top left and right sides of the support base 1. After the motor 552 fixedly connected to the rear side of the slide housing 551 starts, it generates rotational power. The power is transmitted to the threaded rod 553 fixedly connected to the output end of the motor 552, causing the threaded rod 553 to rotate inside the slide housing 551. Since the threaded rod 553 is threadedly connected to the slide table 554, and the slide... The top of the platform 554 is fixedly connected to the bottom of the platform 51. The rotation of the threaded rod 553 will drive the slide 554 to slide along the axial direction of the threaded rod 553, thereby moving the platform 51 and the cantilever base plate 2 and cantilever opening mechanism 4 connected above along the length direction of the slide shell 551 to complete the longitudinal position adjustment. Through the lateral movement driven by the power component 54 and the longitudinal movement driven by the embedded slide assembly 55, the cantilever moving mechanism 5 drives the cantilever base plate 2 and the cutting-related components above to move precisely in the plane, so that the cutting component 46 reaches the required cutting position.

[0050] After the cutting position is adjusted, the cutting height is adjusted. The height of the cutting assembly 46 is adjusted by the cantilever opening mechanism 4 so that the cutting blade 463 reaches the cutting height that matches the fabric to be cut. The bottom of the cylinder 41 in the cantilever opening mechanism 4 is fixedly connected to the top of the cantilever base plate 2. When the cylinder 41 is activated, it generates a vertical driving force. The driving force acts on the lifting plate 42 fixedly connected to the top of the cylinder 41, causing the lifting plate 42 to move vertically. Sliding columns 43 are fixedly connected to the left and right sides of the top of the cantilever base plate 2. The outer walls of the two sliding columns 43 are provided with lifting frame assemblies 45. The movement of the lifting plate 42 will synchronously drive the lifting frame assembly 45 to slide vertically along the outer walls of the sliding columns 43. The inner walls of the two outer frames 451 are slidably connected to the outer walls of the sliding column 43. During the sliding process, the rotating column 452, which is rotatably connected around the inner walls of the two outer frames 451, will rotate accordingly, reducing the friction between the outer frames 451 and the sliding column 43 and ensuring a smooth and stable lifting process. At the same time, a fixed frame 44 is fixedly connected to the rear side of the cantilever base plate 2. The fixed frame 44 provides the mounting and positioning base for the components of the entire cantilever opening mechanism 4, preventing the components from shifting position during the lifting process. The cylinder 41 provides vertical driving force, and the lifting plate 42 transmits power to drive the lifting frame assembly 45 to slide along the sliding column 43. Combined with the reduced friction of the rotating column 452, the lifting frame assembly 45 achieves a stable and smooth vertical movement, allowing the cutting assembly 46 to reach the appropriate cutting height.

[0051] Once the height of the cutting assembly 46 is adjusted to the correct position, the final cutting operation begins. The rear of the buffer frame 461 in the cutting assembly 46 is fixedly connected to the front of the outer frame 451, and together with the outer frame 451, it completes the height positioning. The buffer frame 461 provides stable installation support for subsequent components. The reversing motor 462 fixedly connected to the top of the buffer frame 461 is started. The output end of the reversing motor 462 drives the fixedly connected cutting blade 463 to rotate. Driven by the reversing motor 462, the cutting blade 463 performs the cutting operation on the fabric to be cut. During the cutting process, the sliding column 43 not only provides sliding guidance for the lifting frame assembly 45, but also provides stable installation support for the cutting assembly 46, ensuring that the cutting assembly 46 remains in a stable position during the cutting process, further ensuring cutting accuracy. Through the installation support provided by the buffer frame 461 and the rotation of the cutting blade 463 driven by the reversing motor 462, the cutting assembly 46 achieves the effect of accurately cutting the fabric to be cut, and finally completes the entire garment cutting operation.
