An automatic sewing unit sewing machine head position lifting device

Abstract

The invention relates to a lifting device for a machine head position of a sewing machine with an automatic sewing unit. The lifting device for the machine head position of the sewing machine with the automatic sewing unit comprises a jack component, a first chassis and a second chassis, wherein the upper end of the jack component is fixedly connected with the first chassis; at least one pair of X-directional straight guide rails is arranged on the first chassis; an upper end of an X-directional straight slide block is fixedly connected with the second chassis; the second chassis is used for loading the sewing machine; a stretching rod handle is fixedly arranged at one end of a stirring rod of a stirring rod interlocking part; a chuck E is arranged at the other end of the stirring rod; a handle pin of the stretching rod handle is inserted in a first positioning hole; a rotating shaft of a jack turntable is locked by the chuck E; the stretching rod handle is rotated; the handle pin is inserted in a second positioning hole; the second chassis is moved for a small distance along X direction; when the sewing machine is lifted along Z direction, a detecting part and an automatic part of the sewing machine are avoided, and meanwhile, the chuck E of the stirring rod is departed from the rotating shaft of the jack turntable, so that the jack unlocking is realized and the lifting of the sewing machine can be adjusted by adjusting the jack turntable.

Description

technical field [0001] The invention relates to a related component of a sewing machine, in particular to an automatic sewing unit sewing machine head position lifting device, which belongs to the technical field of sewing machines. Background technique [0002] At present, the position of the head of the automatic sewing unit sewing machine on the market is fixed on the frame, because the automatic sewing unit sewing machine is equipped with many auxiliary automatic components and detection components, which limits the space range of the original sewing machine threading and thread passing , As a result, it is inconvenient to install needles, change threads and maintain the sewing machine. Contents of the invention [0003] The technical problem to be solved by the present invention is: the various auxiliary automatic parts and detection parts installed on the head position of the existing automatic unit sewing machine limit the space range of threading and passing of the...
