Everyone hopes to wear comfortable, decent clothes that can fully reflect their appearance, and they are very particular about clothing. Among them, welts are often ironed on some cloth materials and nylon materials to increase the structural performance and function of the materials. The existing processing technology for welts is to use a small ironing machine to superimpose the welts and the fabrics to be spliced ​​together and then perform ironing and pressing.

[0003] At present, a Chinese utility model with publication number CN117341219A discloses a multifunctional small clothing ironing machine, including a roller driving assembly provided with a driving roller; a hot air pipeline extending into the roller and connected with a plurality of vents, and a hot air pipeline for spraying hot air on the roller; a strip material channel is provided in the main body mounting plate, and a blowing quick plug and a pressing hole penetrating to the strip material channel are provided on the opposite sides; a fixed knife, a cutting knife and a cutting knife control mechanism for controlling the cutting knife to rotate around a fulcrum and the moving knife to achieve shearing are provided on the main body mounting plate.

[0004] Although the cutter control mechanism on the existing small ironing machine can control the cutter to rotate around the fulcrum and cooperate with the fixed knife to achieve shearing; however, under long-term shearing between the cutter and the fixed knife, a gap is likely to appear between the fixed knife and the cutter. Since the material of the fillet is soft and the thickness is thin, when the gap between the fixed knife and the cutter is large, the fillet may not be cut or the shearing edge of the fillet may be uneven, which ultimately affects the quality of ironing.
