Description

Technical Field

[0001] This utility model relates to the field of fabric cutting equipment technology, specifically to an automatic garment cutting device. Background Technology

[0002] In large-scale production scenarios, such as garment factories for well-known fast fashion brands, tens of thousands of meters of fabric need to be processed daily, precisely cutting them into various garment components. Only with the help of advanced cutting equipment can the high-speed operation of the cutting process be ensured, meeting the needs of subsequent intensive sewing, ironing, and other processes, thereby enabling rapid product launches and consolidating market share. For small custom workshops, precise cutting is a key means of interpreting personalized design concepts. Based on each customer's unique body measurements and fashion preferences, the fabric must be carefully cut into garment pieces that fit individual needs, thereby winning high praise and customer loyalty.

[0003] However, existing garment cutting equipment has many shortcomings in meeting these needs. In terms of fabric conveying, many traditional devices suffer from poor feeding stability. Some feeding devices use simple roller structures, lacking effective anti-slip and tension control measures, which can easily lead to fabric slippage, misalignment, or stretching deformation during conveying. This can damage the fabric surface, causing wrinkles or scratches and reducing the product yield. Existing garment cutting equipment also needs improvement in terms of automation integration and ease of operation. Many devices lack effective coordination between their various functional modules; for example, the connection between fabric conveying and cutting operations is not smooth enough, requiring considerable manual intervention to complete the entire cutting process. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automatic garment cutting device, comprising a winding roller for winding fabric, a feeding assembly disposed on the side of the winding roller for driving the fabric to move, a conveying table disposed on the side of the feeding assembly, a cutting assembly disposed above the conveying table, a receiving table disposed on the side of the conveying table, and a pressing assembly disposed above the receiving table, with a cutting seam provided between the conveying table and the receiving table for the cutting assembly to perform cutting; the feeding assembly comprises two opposing upright plates, with two feeding rollers disposed vertically between the two upright plates, a rotating shaft fixed to the end face of the feeding roller and rotatably connected to the upright plates, and multiple rubber dots fixed to the outer surface of the feeding roller to increase the friction between the feeding roller and the fabric.

[0005] Furthermore, the feeding assembly also includes a servo motor mounted on one of the vertical plates. The output end of the servo motor is connected to an output rod, which is fixed to the end face of one of the feeding rollers. Below the output rod is a connecting rod that is rotatably connected to the vertical plate. The connecting rod is fixed to the end face of another feeding roller. Spur gears are fixed to the outer sides of both the output rod and the connecting rod, and the two spur gears mesh with each other.

[0006] Furthermore, the cutting assembly includes an inverted U-shaped cutting mounting frame. A butterfly birch is slidably connected to the bottom surface of the cutting mounting frame via a dovetail groove structure. A slide plate is fixed to the bottom of the butterfly birch, and a side plate is fixed to the bottom of the slide plate. A stepper motor is mounted on the side of the side plate, and a cutting circular blade is connected to the output end of the stepper motor. A drive motor is mounted on the bottom surface of the cutting mounting frame, and a lead screw is connected to the output end of the drive motor. The lead screw is connected to the slide plate, and the axis of the lead screw is in the direction of the cutting seam, allowing the cutting circular blade to pass through the cutting seam.

[0007] Furthermore, the pressing assembly includes an inverted U-shaped pressing mounting bracket, a linear driver is mounted on the bottom surface of the pressing mounting bracket, and a pressing plate is fixed to the telescopic end of the linear driver.

[0008] Furthermore, positioning strips are placed on the receiving table.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. The servo motor and dual-feed roller structure in the feeding assembly achieve stable and efficient fabric conveying. The servo motor precisely controls the speed and direction of rotation of the feeding rollers. Through the meshing transmission of spur gears, the two feeding rollers achieve precise counter-rotation, ensuring that the fabric maintains uniform tension and a stable speed throughout the conveying process. The rubber dots on the outer surface of the feeding rollers effectively increase the friction between the rollers and the fabric, preventing slippage and ensuring conveying stability even when conveying thin or smooth fabrics. This stable and efficient conveying method not only improves production efficiency and reduces jamming and delays during fabric conveying, but also ensures that the fabric is not damaged during conveying, providing a good foundation for subsequent cutting processes and improving the continuity and reliability of the entire cutting process.

[0011] 2. This automatic garment cutting device, through the optimized design and coordinated operation of its components, improves the overall production efficiency and adaptability of the equipment to a certain extent. In terms of production efficiency, the connection between each link, from fabric feeding, positioning, cutting to pressing, is close and smooth, with a high degree of automation, reducing the time and workload of manual intervention.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] An automatic garment cutting device, such as Figure 1 As shown, it includes a winding roller 1 for winding fabric, a feeding assembly is provided on the side of the winding roller 1 for driving the fabric to move, a conveying table 3 is provided on the side of the feeding assembly, a cutting assembly is provided above the conveying table 3, a receiving table 5 is provided on the side of the conveying table 3, a pressing assembly is provided above the receiving table 5, a positioning strip 8 is placed on the receiving table 5, and a cutting seam 7 is left between the conveying table 3 and the receiving table 5 for the cutting assembly to cut.

[0021] The winding roller 1 serves as the initial placement and supply source of the fabric, allowing it to unfold orderly into subsequent processes. The feeding assembly is responsible for stably conveying the fabric from the winding roller 1 to a specific position, a crucial link in ensuring the continuity of the entire cutting process. The conveyor table 3 provides a stable bearing surface for the fabric before cutting, ensuring it is at the appropriate operating height and position. The cutting assembly, located above the conveyor table 3, can precisely cut the fabric. The receiving table 5 receives the cut fabric or garment pieces for easy subsequent handling and collection. The pressing assembly firmly fixes the fabric on the receiving table 5 during cutting, preventing fabric displacement. The positioning strip 8 provides an accurate reference for fabric placement, while the cutting seam 7 provides a spatial channel for the operation of the cutting circular blade 405, allowing the cutting action to proceed smoothly.

[0022] like Figure 1 and Figure 2 As shown, in this embodiment, the feeding assembly includes two opposing vertical plates 201, with two feeding rollers 202 arranged vertically between the two vertical plates 201. A rotating shaft 203 is fixed to the end face of each feeding roller 202 and rotatably connected to the vertical plate 201. Multiple rubber dots 204 are fixed to the outer surface of each feeding roller 202 to increase friction with the fabric. A servo motor 205 is mounted on one of the vertical plates 201, and an output rod 206 is connected to the output end of the servo motor 205. The output rod 206 is fixed to the end face of one of the feeding rollers 202. A connecting rod 207, rotatably connected to the vertical plate 201, is arranged below the output rod 206 and fixed to the end face of the other feeding roller 202. Spur gears 208 are fixed to the outer surfaces of both the output rod 206 and the connecting rod 207, and the two spur gears 208 mesh with each other.

[0023] The structure of the upright plate 201 and the rotating shaft 203 ensures the stable rotation of the feeding roller 202, reducing fabric conveying fluctuations caused by structural instability. The rubber dot 204 significantly improves the feeding roller 202's gripping ability, effectively conveying both smooth and thick fabrics, thus enhancing the equipment's adaptability to different materials. The servo motor 205, in conjunction with the transmission components, enables precise control of the feeding process, allowing adjustment of the fabric conveying speed and tension according to cutting requirements, thereby improving the stability and reliability of fabric conveying.

[0024] like Figure 1 and Figure 3As shown, in this embodiment, the cutting assembly includes an inverted U-shaped cutting mounting frame 401. A butterfly birch 403 is slidably connected to the dovetail groove 402 structure on the bottom surface of the cutting mounting frame 401. A slide plate 404 is fixed to the bottom of the butterfly birch 403. A side plate is fixed to the bottom of the slide plate 404. A stepper motor is mounted on the side of the side plate. The output end of the stepper motor is connected to a cutting circular blade 405. A drive motor 406 is mounted on the bottom surface of the cutting mounting frame 401. A lead screw 407 is connected to the output end of the drive motor 406. The lead screw 407 is connected to the slide plate 404. The axis of the lead screw 407 is in the direction of the cutting seam 7. The cutting circular blade 405 can pass through the cutting seam 7.

[0025] The cooperation between the dovetail groove 402 and the butterfly stalk 403 ensures the cutting trajectory of the cutting circular blade 405 by the movement of the sliding plate 404. The transmission method of the drive motor 406 and the lead screw 407 realizes the control of the position of the cutting circular blade 405, making the cutting process highly automated. It can quickly complete the cutting task according to the preset program and improve the overall production capacity of the equipment.

[0026] like Figure 1 and Figure 4 As shown, in this embodiment, the pressing assembly includes an inverted U-shaped pressing mounting bracket 601, a linear driver 602 is mounted on the bottom surface of the pressing mounting bracket 601, and a pressing plate 603 is fixed to the telescopic end of the linear driver 602.

[0027] The working principle of this utility model is as follows:

[0028] Fabric feeding preparation: First, the fabric is wound onto the winding roller 1, and then one end of the fabric is pulled to the feeding assembly. Two feeding rollers 202 are arranged vertically between the two upright plates 201 of the feeding assembly. The rubber dots 204 on the outer surface of the feeding rollers 202 increase the friction between the fabric and the rollers, ensuring that the fabric can stably adhere to the feeding rollers 202. At this time, the servo motor 205 mounted on one of the upright plates 201 is started. The output end of the servo motor 205 drives the output rod 206 to rotate. Since the output rod 206 is fixed to the end face of one of the feeding rollers 202, that feeding roller 202 rotates accordingly. Meanwhile, the connecting rod 207 below the output rod 206 is fixed to the end face of another feeding roller 202, and the spur gear 208 on the outer side of the output rod 206 and the connecting rod 207 meshes. When the output rod 206 rotates, the connecting rod 207 is driven to rotate in the opposite direction through the meshing transmission of the spur gear 208, so that the two feeding rollers 202 rotate in opposite directions, and the fabric is smoothly pulled from the winding roller 1 and transported to the top of the conveyor table 3.

[0029] Fabric Cutting Positioning: After the fabric is conveyed above the conveyor table 3, it can be initially positioned using the positioning strips 8 placed on the receiving table 5 according to the cutting requirements. The positioning strips 8 help the operator determine the position of the fabric in the cutting direction. At this time, the linear drive 602 of the pressing assembly is activated, and the telescopic end of the linear drive 602 extends downward, driving the pressing plate 603 to descend. The pressing plate 603 presses evenly on the fabric, firmly fixing the fabric on the receiving table 5 and preventing the fabric from moving or shifting during the cutting process.

[0030] Cutting operation execution: The drive motor 406 of the cutting assembly starts, and the output end of the drive motor 406 drives the lead screw 407 to rotate. Since the lead screw 407 is connected to the slide plate 404, and the slide plate 404 is slidably connected to the bottom surface of the cutting mounting frame 401 through the side plate, the butterfly hull 403, and the bottom surface of the cutting mounting frame 401, the slide plate 404 begins to move along the axis of the lead screw 407 (i.e., the direction of the cutting seam 7) under the rotation of the lead screw 407. At the same time, the stepper motor installed on the side of the side plate starts, and the output end of the stepper motor drives the cutting circular blade 405 to rotate at high speed. As the slide plate 404 moves, the rotating cutting circular blade 405 cuts the fabric through the cutting seam 7 between the conveyor table 3 and the receiving table 5. Driven by the drive motor 406 and the lead screw 407, the cutting circular blade 405 can accurately cut the fabric along a predetermined cutting path. Furthermore, through the control of the stepper motor, the rotation speed and cutting force of the cutting circular blade 405 can be adjusted according to different cutting requirements to adapt to the cutting of fabrics of different thicknesses and materials.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
