Description

Technical Field

[0001] This invention relates to the field of clothing design technology, and in particular to a punching and cutting device for clothing production. Background Technology

[0002] The field of apparel design technology encompasses multiple aspects, including style design, structural design, process design, and manufacturing. Its core content involves innovating and optimizing the styling, color, and fabric combinations of garments, combining principles of ergonomics and aesthetics with practical production needs to transform design concepts into apparel products that meet market demands. This overall technical field involves not only initial creative conception and drawing but also various technical stages in the garment production process, such as fabric selection, processing, cutting, sewing, and post-production finishing. These stages work together to ensure both the quality of the garment products and production efficiency.

[0003] One type of perforation and cutting device for garment production refers to a specialized device that combines perforation and cutting functions in the garment production and design process. The technical aspects addressed by this patent cover both perforation operations at specific locations on garment fabrics and cutting the fabrics according to designed dimensions and shapes. Specifically, it features an adjustable perforation component, including a perforation needle drive mechanism that adjusts the pressure and stroke of the perforation needle according to the material and thickness of the garment fabric to achieve precise perforation; it also includes a cutting component with a blade transmission structure that moves the blade according to a preset cutting path to complete the cutting of the garment fabric.

[0004] Existing technologies can only adjust the punching pressure and stroke, and cut according to a preset path. They cannot flexibly adjust the position and angle in multiple directions, lack intuitive positioning and real-time data support, and the position is prone to deviation when cutting or punching clothing. Manual reset is required after driving. There is no buffer structure and the operation object cannot be switched, which leads to limited operation when facing complex garment production needs, inaccurate positioning, unstable cutting quality, easy equipment wear and tear, and low efficiency in continuous operation.

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1: A punching and cutting device for garment production, see reference. Figure 1The device includes two support legs 1, which provide a stable foundation for the entire device, effectively preventing shaking during punching and cutting operations and ensuring the stability of fabric processing during the design process. A design platform 2 is located on the upper end of the support legs 1, serving as the operating platform for the entire device. The design platform 2 provides convenient operating space for placing and positioning the fabric, as well as subsequent punching and cutting operations, facilitating various operations for the operator. A fabric placement plate 5 is located on the inner surface of the design platform 2 to fix the fabric, ensuring stable fixation of the raw material and preventing displacement during fabric processing, thus ensuring the accuracy of cutting or punching. A positioning structure 3 is located on the inner surface of the design platform 2, and a cutting and punching structure 4 is slidably connected to the outer surface of the positioning structure 3. The positioning structure 3 and the cutting and punching structure 4 work together to achieve precise positioning and efficient design of the fabric.

[0034] The punching and cutting device designed in this invention, through the cooperation of positioning structure 3, enables flexible adjustment of the cutting and punching position and angle in multiple directions. With the assistance of positioning structure 3, intuitive positioning reference and real-time data detection are achieved for convenient and accurate control. Through the cooperation of cutting and punching structure 4, stable position is achieved during design and cutting to avoid displacement. Through the cooperation of drive component 44, automatic reset is achieved after driving for continuous operation. Through the connection of cutting component 43, impact is reduced. Through the cooperation of drive component 44, multiple functions are achieved, thereby improving positioning accuracy, operational flexibility and convenience, design precision and stability, garment production quality and equipment lifespan.

[0035] In Example 2, based on Example 1, the sliding block 34 moves stably and smoothly in a predetermined direction through the cooperation of the guide rail 31 and the sliding block 34. The rotational connection between the movable rod 32 and the sliding block 34 allows for flexible angle adjustment to adapt to different garment processing needs. The sliding connection between the limiting tube 33 and the movable rod 32 serves to connect and limit the two. The sliding cooperation between the cutting and punching structure 4 and the limiting tube 33, combined with the angle adjustment of the movable rod 32 and the movement of the sliding block 34, enables flexible adjustment of the cutting and punching position in multiple directions. The positioning line 35 provides an intuitive positioning reference for the operator. The cooperation between the infrared sensor and the wireless signal transmission device can accurately detect the position of the sliding block 34 in real time and calculate the angles of the limiting tube 33 and the movable rod 32, providing data support for accurate cutting. The cooperation of the slot 321, the sliding strip 331, the limiting tooth 333, and the rubber ring 334 ensures the flexibility of the adjustment of the movable rod 32 and the limiting tube 33 while facilitating the application of force by the cutting and punching structure 4, thus improving the overall positioning accuracy, operational flexibility, and cutting precision of the equipment.

[0036] For further details, please refer to [link / reference]. Figure 2 and Figure 3The positioning structure 3 includes guide rails 31 symmetrically mounted on the inner surface of the design table 2. Sliding blocks 34 are slidably connected to the inner surfaces of both guide rails 31. The guide rails 31 provide a stable and smooth path for the movement of the sliding blocks 34, ensuring that the sliding blocks 34 can move flexibly in a predetermined direction. Movable rods 32 are rotatably connected to the upper ends of both sliding blocks 34. The movable rods 32 can rotate around the sliding blocks 34, allowing for flexible angle adjustment to adapt to different garment processing needs. Limiting tubes 33 are slidably connected to the outer surfaces of both movable rods 32. The limiting tubes 33 can... The sliding block 34 can slide on the outer surface of the movable rod 32, and at the same time play a certain role in connecting and limiting the two movable rods 32. The cutting and punching structure 4 is sleeved on the outer surface of the limiting tube 33 and slides on the outer surface of the limiting tube 33. This allows the cutting and punching structure 4 to move along the limiting tube 33. Combined with the angle adjustment of the movable rod 32 and the movement of the sliding block 34, the cutting and punching position can be flexibly adjusted in multiple directions. The upper ends of the two guide rails 31 are provided with positioning lines 35. The positioning lines 35 can provide the operator with intuitive positioning reference and further improve the positioning accuracy.

[0037] Furthermore, an infrared sensor for detecting the position of the sliding block 34 is installed inside the guide rail 31. This infrared sensor is connected to the cutting and punching structure 4 via a wireless signal transmission device. The infrared sensor can detect the position information of the sliding block 34 in the guide rail 31 in real time and accurately. When the two sliding blocks 34 are at the same horizontal position, their positions can be clearly determined based on the data detected by the sensor. When the two sliding blocks 34 are not at the same horizontal position, the distances detected by the two sensors are different. Based on this, the angle of the limiting tube 33 and the movable rod 32 can be calculated to achieve angle positioning. These position and angle-related information are transmitted to the cutting and punching structure 4 in a timely manner through the wireless signal transmission device, providing data support for subsequent accurate cutting.

[0038] For further details, please refer to [link / reference]. Figure 4 and Figure 5The movable rod 32 has symmetrical slots 321 on its outer surface. The front end of the limiting tube 33 has a sliding groove 332 that communicates with the rear end. The inner surfaces of the sliding grooves 332 on both sides are slidably connected to sliding strips 331 by blocks. Rubber rings 334 are provided at the junctions of the sliding strips 331 with the sliding grooves 332 on both sides. The rubber rings 334 have good elasticity and reset ability. When no external force is applied, they can drive the sliding strips 331 to reset. Several limiting teeth 333 that are adapted to the slots 321 are arranged and fixed in an array on the side of the sliding strips 331 closest to the movable rod 32. In the initial state, the limiting teeth 333 of the sliding strips 331 are separated from the slots 321. This will not affect the relative sliding between the movable rod 32 and the limiting tube 33, ensuring the flexibility of their adjustment. The side of the sliding strips 331 away from the movable rod 32 is in contact with the cutting and punching structure 4, which makes it easy for the cutting and punching structure 4 to apply force to the sliding strips 331.

[0039] In Example 3, based on Example 2, the sliding cooperation between the sliding seat 41 and the limiting tube 33 provides a moving basis for the cutting and punching operation. The cooperation between the driving component 44 and the cutting component 43 realizes the punching and cutting operation of the fabric. The connection between the display screen 42 and the infrared sensor displays the position and angle information in real time, which makes it convenient for the operator to accurately control the positioning. The cooperation between the U-shaped plate 442 and the compression spring 443 realizes the automatic reset after driving, which is convenient for the next operation. The cooperation between the arc strip 411, the elastic strap 412 and the arc block 445 fixes the relative position of the limiting tube 33 and the movable rod 32 during cutting, ensuring cutting stability and avoiding positional deviation. Overall, it improves the convenience of operation, cutting accuracy and stability.

[0040] For further details, please refer to [link / reference]. Figure 6 The cutting and punching structure 4 includes a sliding seat 41 sleeved on the outer surface of the limiting tube 33 and slidably connected to the limiting tube 33. The sliding seat 41 can slide freely along the limiting tube 33, providing a moving base for the cutting and punching operation. A driving component 44 is provided in the inner cavity of the sliding seat 41, which provides power for the cutting and punching operation. A cutting component 43 is provided at the lower end of the driving component 44 and the lower end of the sliding seat 41. The cutting component 43 directly realizes the punching and cutting operation of the fabric. A display screen 42 is fixedly installed at the front end of the sliding seat 41. The display screen 42 is connected to the infrared sensors in the guide rails 31 on both sides through a signal bus to monitor the real-time position of the sliding block 34. The display screen 42 can display the position and related angle information of the sliding block 34 detected by the infrared sensor in real time, which makes it convenient for the operator to intuitively and accurately control the positioning situation and improve the accuracy of the operation.

[0041] For further details, please refer to [link / reference]. Figure 7The drive assembly 44 includes a U-shaped plate 442 slidably connected to the inner cavity of the sliding seat 41. The U-shaped plate 442 can slide up and down in the inner cavity of the sliding seat 41. A drive handle 441 is provided at the upper end of the U-shaped plate 442, extending through the inner cavity of the sliding seat 41 to the upper end of the sliding seat 41. The operator drives the U-shaped plate 442 to move by manipulating the drive handle 441. A compression spring 443 is symmetrically and fixedly connected to the lower end of the U-shaped plate 442 and fixedly connected to the inner cavity of the sliding seat 41. The compression spring 443 has an elastic reset function, which can drive the U-shaped plate 442 to reset when the drive handle 441 is not under force, so as to facilitate the next operation. The lower end of the drive handle 441 extends through the inner cavity of the sliding seat 41 to the lower end of the sliding seat 41 and is fixedly connected to a connecting plate 444 slidably connected to the cutting assembly 43. The connecting plate 444 can transmit the driving force of the drive handle 441 to the cutting assembly 43, so that the cutting assembly 43 can complete the corresponding cutting action.

[0042] For further details, please refer to [link / reference]. Figure 7 and Figure 8 An arc-shaped strip 411 is symmetrically slidably connected to the inner surface of the sliding seat 41. The arc-shaped strip 411 can slide on the inner surface of the sliding seat 41. Elastic straps 412, which are fixedly connected to the inner wall of the sliding seat 41, are symmetrically arranged on the outer surface of the arc-shaped strip 411. The elastic straps 412 are elastic and can apply tension to the arc-shaped strip 411. Under the action of the elastic straps 412, the arc-shaped strip 411 is located in the groove of the inner wall of the sliding seat 41 and overlaps with the sliding strip 331. The vertical part of the U-shaped plate 442 is close to the arc-shaped strip. One side of 411 is fixedly connected to an arc-shaped block 445. During the downward movement of the U-shaped plate 442, the arc-shaped block 445 pushes the arc-shaped strip 411 to press the sliding strip 331. At this time, the limiting tooth 333 will be engaged in the slot 321, thereby fixing the relative position of the limiting tube 33 and the movable rod 32, ensuring stability during cutting and punching, and avoiding positional deviation. When the arc-shaped block 445 separates from the arc-shaped strip 411, the elastic strap 412 can drive the arc-shaped strip 411 to reset and separate from the sliding strip 331, which facilitates subsequent position adjustment.

[0043] Example 4: Based on Example 3, this example uses the elastic connection between the mounting base 431 and the connecting plate 444 to buffer the impact on the fabric and equipment during cutting or punching. The cooperation between the limiting plate 432 and the punching rod 433 enables the fabric punching operation. The cooperation between the U-shaped plate 434, the cutting blade 436, and the friction wheel 435 enables linear cutting of the fabric through rotation. The cooperation between the turntable 4411, the cable 4412, and the pressure block 4415 enables the switching of the pressure object, which can complete the punching and cutting operations respectively. The spring setting facilitates the reset of each component after operation, which improves the quality of the cut surface or hole, the service life of the equipment, and the versatility of functions.

[0044] For further details, please refer to [link / reference]. Figure 9The cutting assembly 43 includes a mounting base 431 slidably connected to the outer surface of the connecting plate 444. The mounting base 431 can slide relative to the connecting plate 444. A mounting groove 437 is provided at the lower end of the mounting base 431, providing space for the cutting blade 436 and the punching rod 433 to work. The bottom wall of the inner cavity of the mounting base 431 is elastically connected to the connecting plate 444 by a spring. This spring can buffer the impact on the fabric and equipment during cutting or punching, extend the service life of the equipment, and ensure the quality of the fabric cut surface or hole. A limiting plate 432 is slidably connected to the middle of the inner surface of the mounting base 431 by a limiting rod. The limiting rod ensures that the limiting plate 432 can slide stably. A punching rod 433 is fixedly connected to the lower end of the limiting plate 432, extending through the inner cavity of the mounting base 431 to the inner side of the mounting groove 437. The punching rod 433 moves downward under the action of the limiting plate 432 to realize the punching operation on the fabric. The inner cavity of the mounting base 431 is symmetrically arranged on the left and right sides. A second U-shaped plate 434 is provided, extending through the bottom wall of its inner cavity to the inner side of the mounting groove 437. The second U-shaped plate 434 can slide within the mounting base 431. The lower ends of the horizontal portions of the two second U-shaped plates 434 and the lower ends of the limiting plate 432 are elastically connected to the inner wall of the mounting base 431 by springs. These springs facilitate the reset of the second U-shaped plates 434 and the limiting plate 432 after operation. A cutting blade 4 located inside the mounting groove 437 is rotatably connected to the inner surface of the vertical portions of the two second U-shaped plates 434. 36. The cutting blade 436 is used to cut the fabric. Both cutting blades 436 are fixedly connected to friction wheels 435 on the front and rear sides through a drive shaft. When the device moves, the friction wheels 435 rotate due to friction with the fabric surface, which drives the cutting blades 436 to rotate. The rotation of the cutting blades 436 achieves linear cutting of the fabric. When the U-shaped plate 434 moves downward, the cutting blades 436 and the mounting groove 437 are in contact with the fabric surface to ensure smooth cutting operation.

[0045] For further details, please refer to [link / reference]. Figure 10The lower end of the drive handle 441 is fixedly connected to a turntable 4411 that is rotatably connected to the inner cavity of the U-shaped plate 442. The turntable 4411 can rotate within the inner cavity of the U-shaped plate 442. A limiting block 4413 is provided at the upper end of the turntable 4411 to limit its rotation angle. The limiting block 4413 can prevent the turntable 4411 from rotating excessively and affecting the normal operation. Cables 4412 are symmetrically fixedly connected to the outer surface of the turntable 4411. The ends of the two cables 4412 away from the turntable 4411 move downward along the trajectory of the U-shaped plate 442 and are fixedly connected to a connecting block 4414 that slides on the inner wall of the connecting plate 444. The connecting block 4414 can slide on the inner wall of the connecting plate 444. The connecting block 4414 is symmetrically connected to the front end of the connecting block 4414 with connecting ropes 4416. The ends of the two connecting ropes 4416 away from the connecting block 4414 are respectively fixedly connected to the pressing blocks 4415 that are slidably connected to the lower end of the connecting plate 444 through springs. The pressing blocks 4415 remain stable under the action of springs. In the initial state, the pressing blocks 4415 are above the second U-shaped plate 434. When the drive handle 441 is rotated and the connecting block 4414 is slid, the connecting block 4414 pulls the pressing blocks 4415 through the cable 4412 to move them above the limit plate 432. In this way, the pressing object can be switched by rotating the drive handle 441, thereby completing the punching and cutting operations respectively.
