Abstract

The utility model relates to a refitted needle bar left and right rocking mechanism for an automatic oil feed high speed flat seamer and a double synchronous thick material flat seamer, belonging to the industrial sewing machine field, which is a sewing machine designed to aim at the problem of the existing automatic oil feed high speed flat seamer and the existing double synchronous thick material flat seamer which can not do left and right swing. The rocking mechanism comprises a rocking needle rack assembly which is driven to do the right-and-left swing sewing by a main shaft. The main point is that the middle section of the main shaft is additionally provided with a cross gear set to drive a triangular cam, and the motion force is transmitted to a bar fork to do the up-and-down motion. The bar fork is provided with a movable slide block which can do the up-and-down motion in a slide slot. By utilizing the change of the angle inclination degree of the slide slot, the up-and-down motion of the bar fork can be changed into a left-and-right motion to drive the rocking needle rock to do the right-and-left swing. The zigzag sewing tracks can be realized. The mechanism is applied to the application of the automatic oil feed high speed flat seamer and the automatic oil feed double-synchronous thick material flat seamer. The refitted needle bar left and right rocking mechanism has advantages of reasonable structural design, strong firmness of sewing the clothes of the same kind, lower cost and higher use value.
