Description

Technical Field

[0001] The utility model relates to the technical field of traction, in particular to an independent traction mechanism of a servo motor. Background Art

[0002] Traction is generally used for pulling steel wire parts and is widely used in industrial manufacturing. The entire structure is composed of a frame, a motor, a traction wheel, and a guide wheel. It is used for guiding, pulling and feeding the steel wire parts. This traction mechanism is used for pulling the steel wire and assisting in feeding.

[0003] When the traction mechanism is pulling materials, a separate traction wheel and guide wheel are generally used to feed the wire pieces horizontally and straightly. However, since the traction mechanism is used to assist in feeding, it will be used in conjunction with other machines, and the position where feeding is required can be aligned with other machines to facilitate the coordinated feeding of the two. However, the simple straight and horizontal traction feeding method of the ordinary traction mechanism is obviously unable to meet the needs of alignment and matching between the two machines. During transmission, the traction mechanism of the transmission will configure the entire transmission chain, requiring multiple drive chain structures, which is more troublesome and laborious during maintenance. In addition, multiple transmission chain structures are not convenient enough when matching speed information and using system algorithms for control. Utility Model Content
