Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides an underwear overlock sewing machine with automatic edge cutting function, including: a support frame 1, an overlock mechanism 2 connected to the top of the support frame 1, and a sewing needle 3 provided at the bottom of the overlock mechanism 2, and a fixing frame 4 connected to one side of the support frame 1.

[0025] The rough edge cutting assembly includes a connecting plate 6, which is located inside the fixing frame 4. A cutting blade 9 is provided at the center of the bottom end of the connecting plate 6, and pressure plates 11 are provided on both sides of the bottom end of the connecting plate 6. The rough edge cutting assembly is used for rough edge cutting during underwear sewing.

[0026] Specifically, such as Figure 2 As shown, a telescopic cylinder 5 is installed on the inner side of the fixing frame 4, and a connecting plate 6 is fixedly connected to the bottom end of the telescopic cylinder 5. The telescopic cylinder 5 controls the lifting and lowering of the connecting plate 6, so that the cutting blade 9 at the bottom can fit the fabric more closely.

[0027] Specifically, such as Figure 2 As shown, a slider 7 is connected to the inner side of the connecting plate 6, and an elastic guide rod 8 is connected to the inner side of the slider 7. The slider 7 slides back and forth on the inner side of the connecting plate 6, which helps to relieve the cutting tension of the cutting blade 9.

[0028] Specifically, such as Figure 2 As shown, the cutting blade 9 is connected to the bottom of the slider 7. The cutting blade 9 is tilted so that the blade is facing the direction of the fabric movement, which facilitates cutting during the movement.

[0029] Specifically, such as Figure 2 As shown, the inner bottom end of the connecting plate 6 is connected to an elastic connecting rod 10, and four elastic connecting rods 10 are provided. The pressure plate 11 is connected to the bottom end of the elastic connecting rod 10. Under the elastic compression of the elastic connecting rod 10, the pressure plate 11 will elastically press the edge of the overlock fabric.

[0030] The waste collection assembly includes a waste collection box 12, which is located at the rear end of the support frame 1. A handle 15 is connected to one side of the waste collection box 12, and a rotating connecting rod 16 is provided on the inner side of the handle 15. The waste collection assembly is used to collect waste materials cut during overlock sewing.

[0031] Specifically, such as Figure 3 As shown, a sliding block 13 is connected to one end of the waste collection box 12. The sliding block 13 is slidably connected to the support frame 1. An anti-slip pad 14 is connected to the bottom end of the waste collection box 12. The engagement between the sliding block 13 and the support frame 1 realizes the pre-positioning of the waste collection box 12. The anti-slip pad 14 at the bottom further improves the stability of the waste collection box 12.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, a positioning groove 17 is provided on one end of the inner side of the handle 15, and a positioning block 20 is connected to one side of the support frame 1. After the handle 15 is rotated, the positioning groove 17 is locked on the outside of the positioning block 20, thereby realizing the positioning of the waste collection box 12 and the support frame 1.

[0033] Specifically, such as Figure 4 As shown, an elastic connector 18 is connected to the inner side of the waste collection box 12, and a positioning block 19 is connected to one side of the elastic connector 18. The positioning block 19 can be extended and retracted under the elastic connection of the elastic connector 18.

[0034] In this embodiment: the raw edges of the underwear fabric during the overlocking process are cut by a cutting blade 9 with adjustable height and front and back position. During the cutting process, the two sides of the cutting position are pressed by an elastic pressing plate 11 to improve the stability of the cutting. The raw edge is cut at the same time as the overlocking, reducing the processing steps. After the raw edge of the fabric is cut, in order to avoid the raw edge from falling and affecting the processing environment, a waste collection box 12 is used to collect it. The waste collection box 12 is conveniently positioned and installed by a rotatable and fixed handle 15, which facilitates the transfer of waste.

[0035] The specific solution is as follows: When using the overlock sewing machine, the underwear fabric to be processed is placed in the processing position of the support frame 1, and then slowly pushed manually. After processing by the overlock mechanism 2 and the sewing needle 3, the overlock effect is achieved. To improve processing efficiency, the lifting and lowering of the connecting plate 6 is controlled by the telescopic cylinder 5. Then, the connecting plate 6 drives the cutting blade 9 to cut the raw edges of the underwear fabric during overlock sewing. During the cutting process, the elastic connecting rod 10 presses the pressure plate 11 to press firmly on both sides of the cutting position. The cutting tension of the cutting blade 9 is eliminated by the back-and-forth movement of the elastic guide rod 8, ensuring the stability of the raw edge removal. This method enables simultaneous edge trimming during overlock sewing, reducing processing steps and improving efficiency. After trimming the fabric edges, a waste collection box 12 is used to collect them to prevent them from scattering and affecting the processing environment. The waste collection box 12 is pre-positioned by the sliding latch 13 engaging with the support frame 1. The handle 15 can also be rotated to disengage the positioning slot 17 from the positioning block 19, and after rotating 180 degrees, it engages with the positioning block 20. This allows for convenient positioning and installation of the handle 15 and the support frame 1, facilitating the positioning of the waste collection box 12. Conversely, it is also easy to remove, improving the ease of moving the waste collection box 12.
