Problems solved by technology

The rear tugs of the existing lockstitch sewing machines with rear wheels have two forms: external and integrated. For the rear tugs of the integrated flat car, the presser foot and the rear tug are almost lifted separately at present, and two linkage mechanisms need to be set at the same time. In order to work normally, the structure is more complicated, and the installation of this type of rear tugboat takes up a large area, the installation is cumbersome, the debugging is troublesome, and the lack of effective lubrication mechanism is easy to cause inconvenience in use

Abstract

The invention provides a rear towing wheel device for a sewing machine, and belongs to the technical field of machinery. The problems of large occupied area, complexity in mounting and debugging synchronization troubles of a conventional rear towing wheel are solved. The rear towing wheel device for the sewing machine comprises a rear towing wheel, a power mechanism for driving the rear towing wheel to ascend and descend and a linkage mechanism for driving the rear towing wheel to ascend and descend along with a presser foot lifting component, wherein a vertically arranged vertical shaft and a rear towing wheel wrench capable of independently driving the rear towing wheel to ascend and descend are arranged on the rear towing wheel; the power mechanism is arranged between a main shaft and the vertical shaft; the linkage mechanism is arranged between the presser foot lifting component and the rear towing wheel, and is connected with a knee-raised pull rod. According to the rear towing wheel device, the rear towing wheel can be independently lifted through the towing wheel wrench, can ascend and descend through the knee-raised pull rod, and can also be operated by the presser foot lifting component to ascend and descend in a linkage way, so that driving modes are diversified, and high practicability is ensured.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a sewing machine, in particular to a rear tug wheel device of the sewing machine. Background technique [0002] With the continuous development of science and technology and the textile industry, the technology of sewing machines has become more and more mature, and there are more types, including not only household sewing machines, but also industrial sewing machines used in industry, such as lockstitch sewing machines, chain sewing machines, Overlock sewing machine and interlock sewing machine, etc. The rear tugs of the existing lockstitch sewing machines with rear wheels have two forms: external and integrated. For the rear tugs of the integrated flat car, the presser foot and the rear tug are almost lifted separately at present, and two linkage mechanisms need to be set at the same time. In order to work normally, the structure is relatively complicated, and the installation...
