A sock shaping and shaping equipment includes a track, a fan structure, a driving device, a transmission chain mechanism and a standby mechanism. Compared with the existing sock shaping and shaping equipment, the present invention has more reasonable structural design, realizes more effective use of space, and has the characteristics of convenient maintenance. The vertical height of the sock shaping and shaping equipment is reduced by cutting the shaping room, the working center of gravity is lowered, the working stability is increased, and at the same time, it is convenient for transportation and maintenance; by changing the force mode of the driving device, the original closed structure is avoided, and the number of workers is increased. At the same time, it is convenient for the internal monitoring and maintenance of the sock shaping and shaping equipment; through the standby mechanism, the working time of workers is increased, the requirements for work proficiency and the working pressure of workers are reduced, and the cost of the enterprise is reduced; the transmission chain mechanism increases Improve the operation stability of the transmission chain and increase the service life.
