Description

Technical Field

[0001] This utility model relates to the field of garment production equipment technology, specifically a cutting device based on garment production. Background Technology

[0002] As is well known, in the garment manufacturing industry, the cutting process, as a crucial step in transforming design blueprints into actual garment components, directly impacts garment quality, production efficiency, and enterprise costs. With consumers' growing demand for personalized clothing styles, the market offers increasingly diverse styles, from minimalist urban chic to intricate ethnic styles, from modern designs with flowing lines to retro-glamorous court styles. Each style presents unique challenges to cutting techniques.

[0003] Early cutting equipment had a simple motion mechanism, which could only move the cutting head in one direction and lacked multi-dimensional coordinated motion capabilities. When faced with complex cutting tasks, it required multiple manual adjustments, which was cumbersome, error-prone, and inefficient, increasing the company's time and labor costs. At the same time, clothing fabrics are diverse in material and have different physical properties. Traditional mechanical clamping methods are prone to leaving marks on thin fabrics and may not be able to securely fix thick fabrics, causing them to slip. It is difficult to stably fix various types of fabrics. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a cutting device based on garment production, which has the following beneficial effects:

[0016] This garment production-based cutting device, through the coordinated operation of a linear motion mechanism, a rotary motor, and a first motor, enables the laser cutting head to move flexibly in multiple directions and adjust its angle. The linear motion mechanism drives the support frame and related components to move linearly as a whole. The rotary motor rotates the rectangular frame through gear transmission to change the direction of the laser cutting head. The first motor drives the first slider to move the laser cutting head along the direction of the rectangular frame. The combination of these three mechanisms allows the laser cutting head to move along any preset trajectory, accurately completing the cutting of various complex patterns and irregular contours. This meets the cutting path requirements of different styles and designs of garments, greatly expanding the applicability of the device and improving overall production efficiency.

[0017] This garment cutting device utilizes a vacuum suction mechanism that generates negative pressure through the cooperation of a vacuum pump, suction pipe, and multiple suction holes. This pressure firmly fixes the garment fabric to the top wall of the cutting table. Under this negative pressure, the fabric adheres tightly to the cutting table, preventing slippage, wrinkling, or displacement due to the movement of the laser cutting head, airflow disturbances, or other external forces. This ensures that the laser cutting head always operates on the precise position of the fabric along the preset cutting path, fundamentally guaranteeing the positional accuracy of the cut and reducing cutting errors caused by fabric movement. The suction power of the vacuum pump can be adjusted according to the material characteristics of the garment fabric, enabling the device to stably fix various garment fabrics and ensuring the stability of different fabrics during the cutting process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-4A cutting device for garment production includes a cutting table 1, a vacuum adsorption mechanism, and a linear motion mechanism. Support legs 2 are installed at the four corners of the bottom wall of the cutting table 1. The vacuum adsorption mechanism is installed on the top wall of the cutting table 1. A support frame 3 is installed on the rear wall of the cutting table 1. A support frame 4 is mounted on the support frame 3 via the linear motion mechanism. A through groove 5 is horizontally formed on the top wall of the support frame 4. A drive gear 6 is installed in the through groove 5. A rotary motor 7 is installed through the top of the drive gear 6, which penetrates the top wall of the support frame 4. A rotating shaft 8 is rotatably installed in the through groove 5. A driven gear 9 is provided on the outer wall of the rotating shaft 8. The driven gear 9 meshes with the drive gear 6. The bottom end of the rotating shaft 8 penetrates the... A rectangular frame 10 with a lower opening is installed on the bottom wall of the support frame 4. A first screw 11 is rotatably installed inside the rectangular frame 10. A first motor 12 is installed through the side wall of the rectangular frame 10 at one end of the first screw 11. A first slider 13 is threaded onto the outer wall of the first screw 11. A laser cutting head 14 is installed on the bottom wall of the first slider 13. In this embodiment, during use, the garment fabric to be cut is placed on the top wall of the cutting table 1, ensuring that the fabric is laid flat without wrinkles or overlaps. The vacuum adsorption mechanism is activated, and the negative pressure generated by it firmly adsorbs the fabric onto the top wall of the cutting table 1. The suction force can be adjusted according to the material of the fabric to prevent the fabric from sliding or shifting during subsequent cutting, ensuring the cutting position. Accuracy is ensured by operating the linear motion mechanism, which moves the support frame 4 on the support frame 3 along a preset trajectory, adjusting the laser cutting head 14 to a position close to the upper part of the fabric to be cut. Based on the cutting requirements of the garment fabric, the cutting path and range are determined. The rotary motor 7 is started, driving the drive gear 6 to rotate. Since the drive gear 6 is meshed with the driven gear 9, the driven gear 9 rotates with the drive gear 6, thereby driving the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 causes the rectangular frame 10 to rotate, adjusting the laser cutting direction to adapt to different cutting requirements. The first motor 12 is then started, driving the first screw 11 to rotate. The first slider 13 on the outer wall of the first screw 11 rotates within the rectangular frame 10. Under the constraint of the movement, the laser cutting head 14 moves along a predetermined direction. During the movement, the laser cutting head 14 emits a laser beam to cut the clothing fabric below. During the cutting process, the position of the support frame 4 can be adjusted by the linear movement mechanism according to actual needs, the direction of the rectangular frame 10 can be adjusted by the rotary motor 7, and the position of the first slider 13 can be adjusted by the first motor 12 to achieve cutting of complex paths. After the cutting work is completed, the laser cutting, the first motor 12, the rotary motor 7 and the linear movement mechanism are turned off, the vacuum adsorption mechanism is turned off, the adsorption on the fabric is released, the cut fabric is removed, and the residual fabric waste on the cutting table 1 and the laser cutting is cleaned to prepare for the next cutting work.

[0025] Preferably, in this embodiment, the vacuum adsorption mechanism includes suction holes 15, suction pipes 16, a horizontal plate 17, and a vacuum pump 18. The top wall of the cutting table 1 has multiple suction holes 15. A suction pipe 16, penetrating multiple suction holes 15, is installed on one side wall of the cutting table 1. The horizontal plate 17 is installed between the four sets of support legs 2. The vacuum pump 18 is installed on the top wall of the horizontal plate 17. The vacuum pump 18 is connected to the suction pipes 16. When it is necessary to fix the garment fabric, the vacuum pump 18 installed on the top wall of the horizontal plate 17 is activated. The horizontal plate 17, installed between the four sets of support legs 2, provides stable support for the vacuum pump 18, ensuring it does not shake during operation. After the vacuum pump 18 starts working, it draws air through the suction pipe 16 connected to it. Multiple air suction holes 15 penetrate the top wall of the cutting table 1. As the vacuum pump 18 continuously extracts air from the suction pipe 16 and the air suction holes 15, a negative pressure is formed between the air suction holes 15, the top wall of the cutting table 1, and the fabric. Under the action of external atmospheric pressure, the garment fabric placed on the top wall of the cutting table 1 is tightly pressed into the area where the air suction holes 15 are located. The multiple air suction holes 15 are evenly distributed on the top wall of the cutting table 1, which can apply adsorption force to the fabric from multiple points, making the fabric flat and firmly attached to the cutting table 1, avoiding local lifting or loosening. When the cutting work is completed, the vacuum pump 18 is turned off. At this time, the air pressure in the suction pipe 16 and the air suction holes 15 gradually returns to the equilibrium with the external atmospheric pressure, the adsorption force between the fabric and the top wall of the cutting table 1 disappears, and the operator can easily remove the cut fabric.

[0026] Preferably, in this embodiment, the linear movement mechanism includes a groove 19, a second screw 20, a second slider 21, and a second motor 22. The groove 19 is formed in the top wall of the support frame 3. The second screw 20 is rotatably installed in the groove 19. One end of the second screw 20 passes through the side wall of the support frame 3 and is used to install the second motor 22. The second slider 21 is threaded onto the outer wall of the second screw 20. The top wall of the second slider 21 is fixedly connected to the bottom wall of the support frame 4. When it is necessary to adjust the lateral position of the support frame 4 and the laser cutting, the second motor 22 installed on the side wall of the support frame 3 is activated. After the second motor 22 works, it drives the second screw 20 rotatably installed in the groove 19. When rod 20 rotates, the second slider 21 is threaded onto the outer wall of the second screw 20, and the top wall of the second slider 21 is fixedly connected to the bottom wall of the support frame 4. Under the rotation of the second screw 20, the second slider 21 will move linearly in the groove 19 along the axial direction of the second screw 20, thereby driving the support frame 4 and related components (such as the drive gear 6, driven gear 9, laser cutting, etc.) installed on the support frame 4 to move linearly together. The linear movement mechanism drives the support frame 4 and the laser cutting to move linearly. Combined with the movement of other mechanisms, the laser cutting head 14 can cover a larger area on the cutting table 1, meet the cutting needs of different sizes of clothing fabrics, and improve the applicability of the device.

[0027] Preferably, in this embodiment, the plurality of suction holes 15 are distributed in a rectangular array. The rectangular array of suction holes 15 can form a regular and uniform negative pressure area on the top wall of the cutting table 1, so that the adsorption force on various parts of the garment fabric is more balanced. Whether it is the central area or the edge of the fabric, stable adsorption can be obtained, which effectively avoids local lifting, wrinkling or sliding of the fabric due to uneven adsorption force, and ensures that the fabric always remains flat during the cutting process, providing a reliable guarantee for accurate cutting.

[0028] Preferably, in this embodiment, the support frame 4 is an L-shaped design. The L-shaped support frame 4 consists of a horizontal part and a vertical part. The horizontal part can be used to install components such as the drive gear 6 and the rotary motor 7, while the vertical part is connected to the second slider 21 of the linear motion mechanism. This structure can arrange components with different functions in layers in the vertical and horizontal directions, avoiding the stacking of components on the same plane, effectively saving space in the device, making the overall structure more compact, and suitable for use in environments with limited space, such as garment production workshops.

[0029] Preferably, in this embodiment, the rotary motor 7, the first motor 12, and the second motor 22 are all servo motors. Servo motors have extremely high position control accuracy and speed control accuracy, and can rotate precisely according to the instructions issued by the control system, achieving precise control of rotation angle and movement distance. For the rotary motor 7, the rotation angle of the drive gear 6 can be precisely controlled, thereby precisely adjusting the rotation direction of the rectangular frame 10 and the laser cutting. The first motor 12 can precisely control the number of rotations of the first screw 11, so that the first slider 13 drives the laser cutting to achieve precise movement along the rectangular frame 10. The second motor 22 can precisely control the rotation of the second screw 20, so that the second slider 21 drives the support frame 4 to perform precise linear displacement. This high-precision control ensures that the movement trajectory of the laser cutting is highly consistent with the preset cutting path, greatly improving the cutting accuracy of the garment fabric.

[0030] Preferably, in this embodiment, the laser cutting head 14 is a CO2 laser head. The laser wavelength emitted by the CO2 laser head is approximately 10.6 μm. This wavelength has extremely strong absorption for common clothing fabrics such as cotton, linen, silk, wool, and chemical fibers. Whether it is light chiffon or silk, or heavy denim or canvas, the CO2 laser can act on the fabric efficiently and achieve precise cutting through high temperature. There is no need to frequently change cutting tools according to the type of fabric, which greatly improves the versatility of the device for different clothing fabrics.
