Abstract

The invention discloses a handwheel device with a gear adjustment function for a pattern machine. The handwheel device includes a lower main shaft, a gearbox and a driving bearing; a handwheel is fixedly connected to one end of the driving bearing, the other end of the driving bearing penetrates from one side of the gearbox to be connected with a driving gear, a second bearing sleeve is arranged on the junction between the gearbox and the driving bearing and fixed to the side wall of the gearbox, and a driven gear is meshed with the driving gear; the lower main shaft penetrates from the side face of the gearbox to be connected with the driven gear, a first bearing sleeve is arranged on the junction between the gearbox and the lower main shaft and fixed to the side wall of the gearbox, andtwo matched shaft sleeves are arranged on the lower main shaft. By adopting the handwheel device, the lower main shaft can be more conveniently driven to rotate for operators, and the overall noise ofthe lower main shaft and the driving bearing during rotation is smaller.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a hand wheel device with gear adjustment for a pattern machine. Background technique [0002] As one of the common sewing machines, the pattern machine is mainly divided into manual and automatic according to the operation mode. The main difference lies in the drive mode of the lower spindle. For the traditional manual drive mode, the hand wheel is mainly driven by hand and then the lower spindle is driven to rotate. Thereby driving to work. [0003] In the existing structure, the hand wheel directly drives the lower main shaft to rotate, which requires a large driving force and requires the operator to use a lot of effort to operate, which increases the physical exertion of the operator, and the existing lower main shaft is in the process of rotation Due to the existence of large rotational friction, noise is often generated, which brings a certain degree of noise pollu...
