Description

Technical Field

[0001] This utility model belongs to the field of underwear fabric processing technology, and in particular relates to an overlock machine for producing seamless underwear. Background Technology

[0002] Seamless underwear is a one-piece molded garment that is comfortable and fits snugly without leaving any marks. During the manufacturing process, seamless underwear requires an overlocking operation. An overlocking machine is used after the fabric is trimmed to sew the edges of the fabric (also called overlocking) to prevent loose threads from fraying. In existing overlocking processes, while the overlocking machine can move the fabric, it requires manual control of the direction. Manually shifting the fabric in a straight line is difficult, and misalignment can easily result in defective underwear, wasting fabric and increasing manufacturing costs. A search revealed that patent application number 202320038568.7 discloses an overlocking machine for producing seamless underwear. This utility model provides a directional overlocking machine for producing seamless underwear. A seam-locking machine for producing seamless underwear includes a support bracket, a seam-locking device, and a work panel. The seam-locking device is installed on the top right side of the support bracket, and the work panel is slidably connected to the top left side of the support bracket. The machine also includes a moving device, which is provided on the top left side of the support bracket for moving the work panel.

[0003] However, in actual use, the applicant found that when overlocking seamless underwear, personnel need to manually lift the connecting plate first, which drives the pressure plate to move upward, and the pressure plate presses the seamless underwear onto the work panel. Then, personnel need to manually move the work panel to overlock the seamless underwear. The overall structure is quite large and inconvenient for personnel to operate, thus reducing the efficiency of overlocking seamless underwear. In view of this, we propose an overlocking machine for producing seamless underwear. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A seam-locking machine for producing seamless underwear includes a support platform 1. A seam-locking device body 2 is fixedly mounted on the top of the support platform 1. A work panel 4 is slidably connected to the support platform 1 on one side of the seam-locking device body 2. A guide groove 11 is formed on the top of the support platform 1, and the work panel 4 slides along the guide groove 11. Limiting slide posts 41 are symmetrically fixedly arranged at the bottom of the work panel 4. The lower ends of the two limiting slide posts 41 are fixedly connected by a connecting strip 10. Limiting grooves 12 are symmetrically formed on the support platform 1 below the guide groove 11, and the two limiting slide posts 41 slide along the two limiting grooves 12 respectively. A column 5 is fixedly connected to the top of the work panel 4. A support beam 6 is fixedly connected to the upper end of the column 5. A movable plate 3 is slidably connected between the work panel 4 and the support beam 6. A movable column 32 is fixedly installed on the side of the movable plate 3 near the column 5. The upper end of the movable column 32 slides along the groove opened at the bottom of the support beam 6, and the lower end of the movable column 32 slides along the groove opened at the top of the work panel 4. A connecting groove 31 is opened on the movable plate 3. A latching groove 33 is opened on the side of the movable plate 3 with the connecting groove 31. A movable column 7 is movably inserted through the support beam 6 on the rear side of the movable plate 3. The upper end of the movable column 7 is connected by a spring. Spring 8 is elastically connected to support beam 6. Spring 8 is sleeved on movable column 7. The upper end of spring 8 is fixedly connected to the bottom of limit plate 71, and the lower end of spring 8 is fixedly connected to the top of support beam 6. Fabric strip 9 is fixedly connected to the lower end of movable column 7. Connecting slide column 72 is fixedly installed on the front side of movable column 7 and slides along connecting groove 31. By manually pulling movable plate 3 towards column 5, the movable column 7 can be moved upward through the cooperation of connecting groove 31 and connecting slide column 72, thus stretching spring 8. At this time, movable column 7 can drive fabric strip 9 upward. The process involves placing the underwear fabric to be hemmed on the work panel 4 below the fabric pressing strip 9, adjusting the fabric position as needed, and finally releasing the movable plate 3. Under the elastic force of the spring 8, the movable column 7, along with the fabric pressing strip 9, can move downwards to reset. This allows the fabric pressing strip 9 to automatically press the underwear fabric. Finally, by manually pushing the column 5, the work panel 4, along with the pressed underwear fabric on it, can be moved forward. This allows the hemming of seamless underwear to be completed using the hemming machine body 2. Its overall structure is more compact, making it easier for personnel to operate and improving the hemming efficiency of seamless underwear.

[0022] Working principle: When using, hold the column 5 with your left thumb and let the other four fingers pass through the buckle groove 33. Then, manually pull the movable plate 3 towards the column 5. Through the cooperation of the connecting slide groove 31 and the connecting slide column 72, the movable column 7 will move upward. The upward movement of the movable column 7 will cause the limiting plate 71 to move upward, stretching the spring 8. At the same time, it will also cause the fabric pressing strip 9 to move upward. At this time, the seamless underwear to be edged can be placed on the working panel 4 below the movable column 7 and the position of the underwear can be adjusted as needed. Then, release the movable plate 3. At this time, under the elastic force of the spring 8, the movable column 7 and the fabric pressing strip 9 will move downward to reset. The fabric pressing strip 9 will press the seamless underwear tightly onto the working panel 4. Finally, you can manually pull the column 5 forward. The column 5 will cause the working panel 4 and the seamless underwear pressed on it to move forward together. The edge-locking device body 2 can then quickly edge-lock the seamless underwear.
