Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, and in particular to a fabric cutting and positioning frame that prevents edge curling. Background Technology

[0002] Fabric cutting positioning frames are commonly used auxiliary equipment in garment cutting operations. They can lay out the fabric to be cut flat and accurately fix it in a preset position, helping operators quickly align the cutting line according to the scale markings, avoiding fabric displacement that could lead to cutting size deviations, and improving cutting accuracy and efficiency. Anti-curling is an important process requirement in fabric processing. Due to the fiber structure or weaving characteristics, the edges of fabric are prone to natural curling. Anti-curling treatment can prevent edge wrinkles and misalignment during cutting, ensuring that the edges of the cut fabric pieces are flat, reducing fabric waste in subsequent sewing processes, and at the same time ensuring the edge aesthetics and structural stability of finished garments and fabric products, reducing the rework rate.

[0003] The anti-curling fabric cutting positioning frame mainly consists of a load-bearing frame, precision positioning components, and a special anti-curling structure. During use, the load-bearing frame, typically made of high-strength metal, provides stable support. The positioning components include adjustable scales and sliding clamps to fix the position according to the fabric size. The anti-curling structure is the core component, including synchronous pressure rollers that smooth the fabric as it is fed in, suppressing curling. Additionally, positioning strips provide rigid constraints at the edges. These multiple structures work together to ensure the fabric remains flat and without shifting, improving cutting accuracy.

[0004] In existing technologies, some fabric cutting positioning frames are fixed by manual bolt clamping, which requires repeated tightening operations for adjustment. This is not only time-consuming and labor-intensive, but also makes it difficult to accurately control the clamping force. This can easily lead to the fabric shifting due to being too loose or the fabric being damaged due to being too tight. Therefore, a fabric cutting positioning frame with anti-rolling edge is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fabric cutting positioning frame that prevents edge curling, aiming to improve the problem that some existing fabric cutting positioning frames are prone to damaging the fabric when fixed, making it difficult to meet cutting needs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fabric cutting and positioning frame for preventing edge curling includes a worktable, the outer wall of which has two sliding grooves and is equipped with an adjustment mechanism, a leveling mechanism is installed at the top of the worktable, a fabric support is fixedly connected to the top of the worktable, and a support leg is fixedly connected to the bottom of the worktable. The adjustment mechanism includes a base plate, the outer side of which is slidably connected to the inner wall of the slide groove. A support plate is fixedly connected to the top of the base plate.

As a further description of the above technical solution: The buffer assembly includes a damper, the bottom of which is fixedly connected to the top of the base plate, and a spring is sleeved on the outside of the damper; As a further description of the above technical solution: The leveling mechanism includes two support frames, the bottom of which is fixedly connected to the top of the workbench. A support shaft is fixedly connected to the adjacent side of the two support frames. Two limiting rings are slidably connected to the outer wall of the support shaft. A leveling roller is slidably connected to the adjacent side of the two limiting rings. As a further description of the above technical solution: Two guide frames are fixedly connected to the top of the base plate, and the front and rear sides of the lifting platform are slidably connected to the inner walls of the two guide frames on the adjacent sides respectively. As a further description of the above technical solution: Both guide frames are fixedly connected to the outside of a sliding arm, and the outer wall of the sliding arm is slidably connected to the outer wall of the workbench.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the turntable is driven by a motor, which drives the sliding block connected to the connecting shaft to make a semi-circular motion inside the lifting platform, thereby making the lifting platform make a vertical linear motion. This causes the pressure strip at the bottom of the scale connected to the lifting platform to make a vertical linear motion. With the resistance of the damper and the spring, the flexible clamping and precise positioning of the fabric are achieved. Compared with the prior art, this invention provides convenient adjustment, accurate positioning, and avoids damage to the fabric.

[0008] 2. In this utility model, the leveling roller is fixed by the limiting ring, so that the leveling roller can rotate synchronously with the support shaft. When the fabric moves, its surface contacts the leveling roller, which drives the leveling roller with spiral stripes on its surface to rotate synchronously, thereby achieving the function of smoothing the fabric wrinkles and suppressing edge curling. Compared with the prior art, it has the effect of ensuring that the fabric is flat when entering the subsequent process and improving the flatness of the fabric before cutting.

[0011] 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.

[0012] A fabric cutting and positioning frame to prevent edge curling, as shown in the reference. Figures 1 to 3 The system includes a workbench 1, with a sliding groove 2 on each of the two outer walls along the length of the workbench 1 to accommodate the sliding structure and prevent it from falling off. An adjustment mechanism 3 is installed in the sliding groove 2 to flexibly adjust the fixed position of the fabric. A smoothing mechanism 4 is installed at the top of the workbench 1 near the feeding end to smooth out fabric wrinkles and reduce curling. A fabric support 5 is fixedly connected to the top of the workbench 1 away from the cutting area to support the fabric roll and prevent the fabric from being piled up messily. A support foot 6 with anti-slip rubber pads is fixedly connected to each of the four corners of the bottom of the workbench 1 to enhance overall stability and prevent shaking during cutting. The adjustment mechanism 3 includes a rectangular base plate 301 adapted to the slide 2. The outer side of the base plate 301 is slidably connected to the inner wall of the slide 2. A rectangular support plate 302 is vertically fixed to the top of the base plate 301 to support the drive component. A motor 303 with a horizontally arranged output shaft is fixedly connected to the outer side of the support plate 302 by bolts. A turntable 304 is fixedly connected to the drive end of the motor 303. A cylindrical connecting shaft 305 is rotatably connected to the edge of the turntable 304 away from the motor 303 as a transmission medium. A sliding block 306 is sleeved and fixedly connected to the outer wall of the connecting shaft 305. A lifting platform 307 is slidably connected to the outer wall of the sliding block 306 to support the positioning of the fabric. The sliding block 306 can rotate with the turntable 304 to drive the lifting platform 307 to move up and down. A set of buffer components 308 for buffering pressure and preventing the fabric from being pinched is fixedly connected to the bottom of the lifting platform 307. The buffer assembly 308 includes a vertically arranged damper 3081, which can slow down the descent speed of the lifting platform 307 and avoid rigid impact. The bottom of the damper 3081 is fixedly connected to the corresponding position at the top of the base plate 301. A spring 3082 is sleeved on the outside of the damper 3081 to provide elastic support and adjust the clamping force. The elastic force of the spring 3082 can be adapted according to the thickness of the fabric, so that thin materials are not crushed and thick materials are clamped firmly. Specifically, when the adjustment mechanism 3 is working, it first pushes the rectangular base plate 301 to slide along the inner wall of the slide groove 2 to adjust to the position that matches the size of the fabric. Then, the motor 303 starts, and the drive end of the motor 303 drives the turntable 304 to make a semi-circular motion. The cylindrical connecting shaft 305 connected to the edge of the turntable 304 rotates synchronously with the turntable 304. Since the connecting shaft 305 is fixed to the sliding block 306, the sliding block 306 will slide along the inner wall of the lifting platform 307, thereby driving the lifting platform 307 to make a vertical linear motion. When the lifting platform 307 descends, the buffer component 308 at the bottom plays its role. The damper 3081 slows down the descent speed to avoid rigid impact. At the same time, the external spring 3082 is compressed, and provides a suitable clamping force through elastic deformation. Finally, the lifting platform 307 smoothly presses the fabric, achieving accurate positioning without damaging the fabric.

[0013] Reference Figure 1 and Figure 4 The leveling mechanism 4 includes two triangular support frames 401 to enhance support stability. The bottoms of the two support frames 401 are fixedly connected to the top of the workbench 1 near the feed end on both sides. A cylindrical support shaft 402 is fixedly connected to the adjacent side of the two support frames 401 through a bearing for subsequent component sliding. Two annular limiting rings 403 are slidably connected to the outer wall of the support shaft 402. A leveling roller 404 with spiral stripes on the surface is slidably connected to the adjacent side of the two limiting rings 403 through a bearing. The limiting rings 403 are provided with anti-slip rubber rings inside to help fix the leveling roller 404. The leveling roller 404 can rotate synchronously with the fabric feed, which can help smooth wrinkles and suppress edge curling. Specifically, before the leveling mechanism 4 starts working, two annular limiting rings 403 slide along the cylindrical support shaft 402 to fix the leveling roller 404. The anti-slip rubber rings inside the limiting rings 403 then fit together, allowing the leveling roller 404 to rotate synchronously with the support shaft 402. The triangular support frame 401 stably supports the support shaft 402, ensuring no shaking during operation. When the fabric moves, its surface contacts the leveling roller 404, thereby driving the leveling roller 404 with spiral stripes on its surface to rotate synchronously. The spiral stripes smooth out the fabric wrinkles during rotation, suppress edge curling, and ensure that the fabric is flat before entering the subsequent processes.

[0014] Reference Figure 2 and Figure 3 Two semi-frame-shaped guide frames 309 are symmetrically fixedly connected to the top of the base plate 301. The outer walls of the lifting platform 307 on both sides slide against the inner wall of the guide frame 309 on the side closest to it, ensuring that the lifting platform 307 moves only in the vertical direction and avoids deviation. The outer walls of the two guide frames 309 are vertically fixedly connected with long strip-shaped sliding arms 310. The outer walls of the sliding arms 310 are slidably connected to the outer wall of the worktable 1 through sliders, which can assist the base plate 301 to move smoothly along the slide 2. The inner wall of the lifting platform 307 is fixed with a scale 311 for easy positioning of the fabric. The bottom of the scale 311 is vertically fixedly connected with multiple rectangular connecting blocks 312. The bottom of the connecting blocks 312 is attached with a soft rubber strip 313 to avoid damaging the fabric. The connecting blocks 312 are used to connect the scale 311 and the strip 313. Specifically, when the base plate 301 is pushed, the long strip-shaped sliding arm 310 on the outer side of the top guide frame 309 slides along the outer wall of the worktable 1 via the slider. At the same time, the base plate 301 moves along the slide groove 2. The double guidance ensures that the overall movement is stable. During positioning, the motor 303 drives the lifting platform 307 to move. The outer walls on both sides of the lifting platform 307 slide and fit against the inner wall of the semi-frame guide frame 309. It moves only in the vertical direction without deviating. After being accurately positioned by the scale 311 on the inner wall of the lifting platform 307, the soft rubber pressure strip 313 connected by multiple rectangular connecting blocks 312 at its bottom presses the fabric as the lifting platform 307 descends, which not only avoids damage to the fabric but also achieves stable positioning.

[0015] The implementation principle of this application embodiment is as follows: When the fabric placed on the fabric support 5 passes through the adjustment mechanism 3, the rectangular base plate 301 is first pushed according to the size of the fabric, so that it slides along the slide groove 2 to adjust its position. At this time, the semi-frame guide frame 309 at the top of the base plate 301 drives the outer long strip sliding arm 310, and slides synchronously along the outer wall of the worktable 1 through the slider. The double guide structure ensures that the base plate 301 moves smoothly without deviation. After the position is determined, the motor 303 is started. The drive end of the motor 303 drives the turntable 304 to rotate. The cylindrical connecting shaft 305 at the edge of the turntable 304 moves in a semi-circular motion with it. Through the transmission of the sliding block 306, the lifting platform 307 moves only in the vertical direction along the inner wall of the guide frame 309 to avoid lateral deviation affecting the positioning accuracy.

[0016] Operators can visually observe and accurately position the fabric through the scale 311 on the inner wall of the lifting platform 307. When the lifting platform 307 descends, the bottom buffer component 308 starts to work, the damper 3081 slows down the descent speed to prevent rigid impact on the fabric, the external spring 3082 is compressed, and the clamping force is automatically adjusted according to the thickness of the fabric to achieve the effect of not damaging thin materials and clamping thick materials firmly. Finally, the scale 311, through the soft rubber pressure strip 313 connected by multiple rectangular connecting blocks 312 at the bottom, finally presses the fabric smoothly and evenly to position it, ensuring the integrity of the fabric and the accuracy of the positioning.

[0017] First, place the fabric roll on the fabric support 5, unfold the fabric and feed it into the flattening mechanism 4 from the top of the workbench 1. The triangular support frame 401 ensures the stability of the support shaft 402 and prevents shaking during operation. The limiting ring 403 slides along the support shaft 402 of the flattening mechanism 4. Its internal anti-slip rubber ring fixes the position of the flattening roller 404. The power of the fabric feeding drives the flattening roller 404 to rotate synchronously. During the rotation, the spiral stripes can effectively smooth the wrinkles on the surface of the fabric and further prevent the edges of the fabric from curling, providing a flat fabric base for subsequent cutting.

[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
