Benefits of technology

"The present invention provides a sewing machine with a differential fabric driving teeth displacement control device that can be easily adjusted by operators and repair technicians. The machine also includes an improved lubricating oil supply for smooth operation. The machine is designed to have the axis of the cylinder directed towards the operator, making it more user-friendly. Overall, the invention improves the performance and efficiency of the sewing machine."

Problems solved by technology

In terms of operational convenience, the adjustment mechanisms of longitudinal-cylinder sewing machines are hindered by their sewing mechanisms at the front end of the cylinder; they are both inconvenient for operation and adjustment.
It is not suitable for smaller elements.

Embodiment Construction

[0019] Please refer to FIG. 1, the transverse longitudinal-cylinder sewing machine 9 according to the invention includes a cylinder 92 with the axis directed towards the operator. The axis of cylinder 92 is normal to the axial direction of a entire transverse work station 91 of the sewing machine. The transverse longitudinal-cylinder sewing machine 9 according to the invention includes an automatic thread loosening device 100, a tension adjustment mechanism 200, an automatic thread cutting bi-directional solenoid device 300 and a differential fabric driving teeth displacement control device 400.

[0020] The automatic thread loosening device 100 is mainly to relax the tension of yarns as desired and provides a desirable thread loosening means and location. It includes a thread connection assembly 101, a driving power supply 102 and a linking mechanism 103. The thread connection assembly 101 is located on the rear side of the top section of the sewing machine 9. The driving power suppl...

Abstract

A transverse longitudinal-cylinder sewing machine includes an automatic thread loosening device, a tension adjustment mechanism, an automatic thread cutting bi-directional solenoid device and a differential fabric driving teeth displacement control device. The differential fabric driving teeth displacement control device consists of a primary transmission mechanism, first and second push mechanisms, a rocking mechanism, first and second adjustment mechanisms that are co-axle, and first and second fabric driving mechanisms located inside a cylinder normal to the co-axle. The axial direction of the cylinder is directed towards the operator so that the axis of the cylinder is normal to the entire transverse work station of the sewing machine.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a transverse longitudinal-cylinder sewing machine and particularly to a sewing machine that has a cylinder axis directed towards the operator. The cylinder axis is normal to the axial direction of the entire transverse work station of the sewing machine. BACKGROUND OF THE INVENTION [0002] Conventional industrial high speed cylinder sewing machines generally can be divided into longitudinal-cylinder sewing machine and transverse-cylinder sewing machine. The longitudinal-cylinder sewing machine has a cylinder axis directed towards the operator; the axial direction of the transmission axle of the entire sewing machine is also the same. By contrast, the cylindrical axis of the transverse-cylinder sewing machine is transverse at the front side of the operator. The longitudinal-cylinder sewing machine is widely used for sewing cuffs, elastic wristbands, auxiliary sewing or ornamental sewing for circular articles and the like. ...
