The utility model discloses sweater knitting equipment which comprises a feeding box, a main box body is fixedly installed on the bottom face of the feeding box, and woolen yarn from the feeding box can be guided by a positioning wheel to enter the discharging box according to a set route through cooperation of the feeding box, the main box body, the discharging box, a material passing opening, the positioning wheel and a rubber pad. When the woolen yarn is externally pulled, the positioning wheel can be driven to rotate, the friction force between the rubber pad and the positioning wheel can be increased, and therefore the woolen yarn output speed can be reduced, the threaded rod can drive the rubber pad to move in the output direction of the orientation rod when rotating, and the woolen yarn output speed can be controlled through the threaded rod; due to the braking performance of the rubber sheet, when the knitting woolen yarn is rapidly pulled by external force, the output length of the knitting woolen yarn in a short time can be reduced, and therefore the obvious difference between the tightness of the output knitting woolen yarn and the tightness of the previous knitting woolen yarn and the tightness of the subsequent knitting woolen yarn can be effectively reduced.
