Description

Technical Field

[0001] The utility model relates to an overlock sewing machine, in particular to an overlock sewing machine which can sew neckline ribbing. Background Art

[0002] The physical fitness tops produced in the workshop all have the process of sewing neckline ribbing. The neckline ribbing has great elasticity. Normally, the circumference of the neckline ribbing needs to be 9-12cm smaller than the circumference of the main neckline. Only after sewing can the collar shape be smooth, fit, and not cracked or skewed.

[0003] When sewing this type of product, the equipment that has been used is a three-thread overlock sewing machine. The problems of using this equipment are:

[0004] 1. The efficiency of the three-thread overlock sewing process for the collar ribbing is low, with a daily output of about 750 pieces per worker and high production costs.

[0005] 2. The collar is skewed due to uneven stretching caused by the operator's technique, affecting product quality.

[0006] 3. When sewing, the front collar is too loose, causing the collar to crack, resulting in batch rework.

[0007] 4. Products with irregular collars need to be corrected during the ironing process, resulting in a 30% decrease in the efficiency of the ironing process.

[0008] 5. It is easy to cut the ribbing during the neckline ribbing process, resulting in the neckline ribbing being of different widths, affecting product quality. Utility Model Content

[0009] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide a collar ribbing overlock machine.

[0010] To achieve the above-mentioned purpose, the utility model of the collar rib sewing machine comprises a frame, a table is arranged on the frame, and a sewing machine body is arranged on the table; a U-shaped or inverted L-shaped notch is arranged on the left side of the table of the sewing machine body;

[0011] The main body of the overlock sewing machine at least includes an overlock sewing platform arranged on the left side of the main body of the overlock sewing machine, and a front connecting plate is arranged at the front end of the overlock sewing platform; a ribbing nozzle with a U-shaped cross section is arranged on the front connecting plate; the right edge of the ribbing nozzle is arranged corresponding to the cutting knife of the overlock sewing machine;

[0012] A support is provided at the rear end of the overlocking platform;

[0013] A first support frame is arranged on the table surface corresponding to the right side of the ribbing nozzle; a first roller is arranged on the first support frame;

[0014] A second support frame is arranged downward on the first support frame, and a second roller is arranged on the second support frame;

[0015] The second roller is arranged below the table top and corresponds to the overlocking table.

[0016] Furthermore, the first support frame is provided with a long hole, and the first roller is installed in the long hole of the first support frame by bolts; and / or the second support frame is provided with a long hole, and the second roller is installed in the long hole of the second support frame by bolts.

[0017] The utility model cuts an inverted L-shaped or U-shaped notch on the table to leave space for installing a collar stay. A stay and a roller are installed on the left side of the overlock machine head, which can be adjusted according to the size of the collar rib. A ribbing mouth with the same width as the collar rib is installed on the front connecting plate, and the collar rib is clamped in the ribbing mouth to ensure that the rib is not cut during sewing and the rib width is uniform.
