Description

  The present invention relates to a type of horizontal straight cylinder sewing machine, and more particularly, to a horizontal straight cylinder sewing machine in which the axial direction of the straight cylinder is directed to an operator, and the axis of the straight cylinder is perpendicular to the axial direction of the horizontal working platform of the entire sewing machine. .

  The mechanical design of a traditional industrial high-speed cylindrical sewing machine can be broadly divided into a straight cylindrical sewing machine and a horizontal cylindrical sewing machine. The axial direction of the cylindrical body of the straight cylinder type sewing machine is directed to the operator, and the axial direction of the transmission shaft of the entire sewing machine is the same. Conversely, the axial direction of the cylinder of the horizontal cylinder sewing machine is in front of the operator and is horizontal. Straight cylinder sewing machines are used to paint the cuffs of clothing, elastic bands on cuffs, and to sew various circular products. In terms of the convenience of operation, the adjusting parts of the straight cylinder sewing machine are disadvantageous for operation and adjustment because most of them are blocked by the sewing machine mechanism at the front end of the straight cylinder during use.

  In addition, during the above-described transmission operation of the sewing machine, the mechanism inside the sewing machine needs to supply lubricating oil, whereby each transmission component can be smoothly operated or transmitted. In the lubricating oil supply system, the inside of the transmission shaft or a relatively large volume part is made hollow, and the hollow part is filled with cotton, lubricating oil is dropped in, and the lubricating oil that soaks into the cotton during operation of the mechanism during operation of each mechanism It provides a lubricating effect and ensures smooth operation of the mechanism. However, such a lubricating oil supply system is only suitable for use on a sewing machine having relatively large components, and a small sewing machine is incompatible with a small mechanism because of its small mechanism.

  The main object of the present invention is to solve the above-mentioned disadvantages and to eliminate the existence of the disadvantages, i.e., the present invention drives each transmission mechanism with a common shaft, as well as before being arranged to be perpendicular to the common shaft. The cloth guiding tooth and the rear cloth guiding tooth are driven to perform a tooth feeding operation, and a horizontal straight cylinder sewing machine having a differential cloth guiding stroke control device is configured.

  Another object of the present invention is to adjust the offset amount of the first and second pushing mechanisms by the first and second adjusting mechanisms to effectively control the relative working stroke of the front cloth guiding teeth and the rear cloth guiding teeth thereon. Another object of the present invention is to newly arrange an adjustment mechanism on one side of the straight cylinder type sewing machine so that an operator and a repairman can easily make adjustments.

  A further object of the present invention is to improve the design of the oil supply system required for the transmission of each mechanism, and to operate the mechanism smoothly so that lubricating oil is transmitted between each other during operation of the mechanism. Is to be able to
