Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a transmission component for a lasting machine. Background Technology

[0002] As a core piece of equipment in the textile and footwear industry, the stability of its transmission components and the efficiency of power transmission directly affect the sewing accuracy, feeding smoothness, and service life of the equipment. It is widely used in automated production scenarios such as shoe upper lasting and fabric splicing.

[0003] Traditional lasting machines mostly use a single-drive transmission architecture, which has obvious technical shortcomings: single-motor drive makes it difficult to balance power output and transmission flexibility; after long-term operation, the transmission mechanism is prone to fatigue wear, resulting in weak feeding, slow movement, and affecting production efficiency; transmission gears and shafts are mostly connected by screws, which can easily cause jamming when changing the transmission direction, and the torque transmission loss is large, making it difficult to meet the needs of fine sewing; the driven wheel design lacks targeted optimization, and the bottom surface is not flat enough, resulting in poor corner flexibility during lasting, and the material is prone to wrinkling and deviation during sewing; the motor installation angle of some transmission components is fixed, which cannot adapt to the power requirements of different load scenarios, and the installation space occupies a large area, limiting the sewing vision range and operation convenience. As the textile and footwear industry develops towards automation and precision, the market's requirements for the feeding stability, corner smoothness, and multi-sewing adaptability of lasting machines continue to increase. The problems of power imbalance, transmission jamming, inflexible cornering, and poor adaptability of traditional single-drive transmission components can no longer meet the needs of modern production. Therefore, we propose a transmission component for lasting machines. Utility Model Content
