Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, specifically to an overlock machine for garment processing. Background Technology

[0002] Garment processing is very common in our lives and work. When producing garments, it is generally necessary to overlock the edges of the fabric. Therefore, overlock machines are often used in garment production.

[0003] Chinese patent disclosure CN213835841U discloses a multifunctional overlock machine for garment processing. The machine includes a housing with a control panel on one side of its outer surface and a power interface on the other side. This multifunctional overlock machine for garment processing features a scrap collection mechanism and a power cord fixing mechanism. During operation, a collection box is mounted on the lower end of the worktable via a connecting rail. Scrap materials generated during garment processing can be collected in the box. When maintenance is required, a tool storage box can be pulled out from one side of the collection box to retrieve necessary tools for maintenance. This prevents scrap materials from falling to the ground and affecting cleanup. The power cord fixing mechanism prevents the cord from being dragged on the ground for extended periods, which could damage the cord's insulation and create a potential electrical hazard, thus improving its usability.

[0004] However, it still has the following drawbacks: when the device is used for edge sealing of garments, the fabric is pinched and fed, and the hands are easily injured by needle pricks or other injuries when manually pressing the edge, which reduces the safety of the work. To address this issue, we have proposed an overlock machine for garment processing. Utility Model Content
