Description

Technical Field

[0001] This utility model relates to the field of underwear fabric flattening technology, specifically an underwear fabric flattening device. Background Technology

[0002] In modern lingerie manufacturing, fabric flattening is a crucial step. Flat fabric not only helps improve the precision of lingerie cutting, ensuring consistent dimensions and aesthetically pleasing designs, but also enhances the quality and efficiency of subsequent processing steps such as sewing and printing.

[0003] Some companies still use manual flattening methods, relying on workers to manually pull and iron the fabric to eliminate wrinkles. This method is not only labor-intensive and inefficient, making it difficult to meet the needs of large-scale production, but also, due to the subjectivity and instability of manual operation, the fabric flattening effect is inconsistent, and it is easy for some wrinkles to not be fully unfolded or for the fabric to be deformed due to excessive stretching, affecting the quality of the underwear.

[0004] While some companies use mechanical flattening equipment that improves flattening efficiency to some extent, the equipment structure is often relatively simple, making it difficult to precisely control the pressure and flattening range on the fabric. When processing underwear fabrics of different materials and thicknesses, problems can easily arise such as excessive pressure damaging the fabric fibers, or insufficient pressure resulting in poor flattening effects. Furthermore, most existing equipment lacks flexible movement and adjustment functions, making it difficult to adapt to diverse fabric flattening needs and limiting the flexibility and diversity of underwear production.

[0014] Compared with the prior art, this utility model provides a device for flattening underwear fabric, which has the following beneficial effects:

[0015] 1. This underwear fabric flattening device uses a hydraulic cylinder to lift and lower a raising plate, allowing for flexible adjustment of the distance between the pressure mechanism and the fabric to ensure effective handling of underwear fabrics of varying thicknesses. Simultaneously, a servo motor drives a gear and rack, enabling the fixed frame to move precisely along the fixed frame, driving the pressure mechanism to perform horizontal and vertical flattening operations. This allows for quick and comprehensive flattening of wrinkled fabrics, significantly improving efficiency and effectiveness. The device's lowering and moving mechanism works in conjunction with the pressure mechanism to automate the flattening process. The coordinated operation of the hydraulic cylinder and servo motor requires minimal manual intervention, reducing labor costs, minimizing human error, ensuring stable flattening quality, and adapting to large-scale production needs.

[0016] 2. This underwear fabric flattening device features a combination of guide rods, springs, and damping rods in its pressure mechanism, providing excellent cushioning performance. During the flattening process, the springs and damping rods automatically adjust the pressure according to the actual condition of the fabric, preventing damage such as stretching, deformation, or tearing caused by excessive pressure. This effectively protects the fabric's texture and integrity, improving the product's pass rate. Attached Figure Description

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1-4 This utility model provides a technical solution: an underwear fabric flattening device, including a base 1, a fixed seat 2 fixedly connected to the top of the base 1, support legs 3 fixedly connected symmetrically to the bottom of the base 1 in the front, back and left and right, a lowering and moving mechanism 4 is provided on the front and back sides of the base 1, and a pressure applying mechanism 5 is provided at the bottom of the lowering and moving mechanism 4.

Fixed brackets 411 are fixedly connected between the two sliding sleeves 49 on the surface of the fixed frames 47.

[0030] The top of the lifting plate 45 has holes that match the four fixed rods 42, and the lifting plate 45 is slidably connected to the surface of the four fixed rods 42 through the holes.

[0031] The gear 413 meshes with the rack 48, and the operation of the two servo motors 414 will drive the two connected fixed frames 411 to move.

[0032] Example 2

[0033] Please see Figure 5 Furthermore, based on Example 1, a pressure applying mechanism 5 was obtained.

[0034] The pressure applying mechanism 5 includes a connecting rod 51, which is symmetrically fixed to the bottom of two fixed frames 411. A first connecting plate 52 is fixedly connected to the bottom of the connecting rod 51. Guide rods 53 are equidistantly arranged on the top of the first connecting plate 52. A limit ring 54 is fixedly connected to the surface of the guide rod 53 near the top. A fixing ring 55 is fixedly connected to the surface of the guide rod 53 near the bottom. A spring 56 is sleeved between the first connecting plate 52 and the fixing ring 55 on the surface of the guide rod 53. A second connecting plate 57 is fixedly connected to the bottom of the second connecting plate 57. An arc-shaped strip 58 is fixedly connected to the bottom of the second connecting plate 57. A damping rod 59 is fixedly connected to the top of the second connecting plate 57.

[0035] The top of the first connecting plate 52 has a hole that matches the guide rod 53, and the guide rod 53 passes through the surface and slides up and down in the hole.

[0036] One end of the spring 56 is fixedly connected to the bottom of the first connecting plate 52, and the other end of the spring 56 is fixedly connected to the top of the fixing ring 55.

[0037] The top end of the damping rod 59 is fixedly connected to the bottom of the first connecting plate 52.

[0038] In actual operation, when this device is used, firstly, the underwear fabric that needs to be flattened is placed on the base 1, with the fixed seat 2 as a reference support, ensuring that the fabric is in a suitable working area. At this time, the entire device is stabilized by the support legs 3 symmetrically distributed at the bottom of the base 1. Then, the lowering and moving mechanism 4 is activated. The hydraulic cylinder 44 at the top of the connecting frame 43 starts to work, and the output end of the hydraulic cylinder 44 pushes the lifting plate 45 to slide downward along the four fixed rods 42. Since the top of the lifting plate 45 has holes that match the fixed rods 42, this design ensures the smoothness of the lifting plate 45's downward movement, allowing the fixed frame 47 and the connected pressure mechanism 5 to accurately approach the fabric. When the pressure mechanism 5 approaches the fabric, the servo motors 414 on the front of the two fixed frames 411 are activated. The servo motors 414 drive the rotating shaft 412 to rotate, and the gears 413 on the surface of the rotating shaft 412 rotate accordingly. Because gear 413 meshes with rack 48 on the inner wall of fixed frame 47, the rotation of gear 413 is converted into the movement of fixed frame 411 along fixed frame 47 in the lateral or longitudinal direction, thereby driving pressure mechanism 5 to move on the fabric surface. During the movement of pressure mechanism 5, its unique structure plays a role. When arc-shaped strip 58 contacts the fabric, if the fabric has wrinkles, the fabric will exert a certain reaction force on arc-shaped strip 58. At this time, second connecting plate 57 will drive guide rod 53 to slide upward in the hole of first connecting plate 52, compressing spring 56, while damping rod 59 will also contract accordingly. The buffering effect of spring 56 and damping rod 59 can automatically adjust the pressure, avoiding excessive pressure that could damage the fabric. As the servo motor 414 continues to run, the pressure mechanism 5 moves continuously on the fabric surface. Through the elastic reset of the spring 56 and the stabilizing effect of the damping rod 59, the arc strip 58 continuously applies appropriate pressure to the fabric, gradually smoothing out the wrinkles. When the fabric smoothing is completed, the hydraulic cylinder 44 reverses its operation, driving the lifting plate 45 and the pressure mechanism 5 to slide upwards and reset along the fixed rod 42, so as to perform the next fabric smoothing operation.
