A sewing machine for fabric sewing

Abstract

The invention relates to the technical field of textile equipment, and discloses a lockstitch sewing machine for fabric sewing, comprising a left shaft member, one end of the left shaft member is fixedly installed with a left fixing sleeve on the top, and one end of the left shaft member is externally fixedly installed There are lower bar teeth, and a rotating rod is fixedly sleeved in the middle of one end of the left shaft piece. The present invention can avoid the multiple distribution of the flow velocity and the energy consumption caused by the impact when the lubricating oil is poured into the gap of the rotating parts through the fixed sleeve parts of the curved surface, thereby effectively accelerating the filling efficiency of the lubricating oil, and adopting a specific shape When the lubricating oil flies out along the gap, the protruding ends of the upper and lower fence teeth can effectively intercept the splashing oil droplets. The gap changes from small to large, and the splashed oil droplets are subjected to great changes in flow velocity in the two sudden gaps, resulting in turbulent flow, resulting in energy loss, and then effectively stopping the splashing movement and preventing the oil droplets from flying out. .

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a lockstitch machine for fabric sewing. Background technique [0002] Lockstitch machine is a kind of precision equipment that sews or sews single-layer or multi-layer fabrics. It is mainly composed of a machine head, a platen and a frame. The presser foot of the machine head is used to press the fabric, and then the needle is used to send the sewing machine. The mutual cooperation of the cloth teeth and the shuttle wheel makes the upper thread and the bottom thread intertwined on the sewing material, so as to complete the track sewing of the material. [0003] Among them, in the head of the lockstitch machine, the needle mechanism of the sewing machine is generally driven by a high-speed runner, so as to achieve the effect of rapid sewing. It is lubricated and anti-wear. In the prior art, the oil dripping method of the rotating parts is as shown in the appendix of the...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing locket sewing machine proposed in the background technology, the present invention provides a locket sewing machine for cloth sewing, which can accelerate the flow of lubricating oil and reduce flow resistance, which is beneficial to the timely delivery of lubricating oil. Supplement, and effectively prevent the splashing of residual lubricating oil, solve the technical problems raised in the above background technology
