Lockstitch sewing machine for cloth sewing

Abstract

The invention relates to the technical field of textile equipment, and discloses a lockstitch sewing machine for cloth sewing. The lockstitch sewing machine comprises a left shaft part, a left fixing sleeve is fixedly mounted at the top of one end of the left shaft part, a lower fence tooth is fixedly mounted outside one end of the left shaft part, and a rotating rod is fixedly connected to the middle part of one end of the left shaft part in a sleeving manner. By means of the fixing sleeve part with the arc-shaped curved surface, when lubricating oil is poured into a gap of a rotating part, flow speed distribution for multiple times and energy consumption caused by impact can be avoided, and then the pouring efficiency of the lubricating oil is effectively improved, the upper fence tooth and the lower fence tooth with specific shapes are adopted, and when lubricating oil flies out along the gap, the protruding end of the upper fence tooth and the protruding end of the lower fence tooth can effectively intercept splashed oil drops, in addition, the gap between the upper fence tooth and the lower fence tooth is changed from small to large, the splashed oil drops are subjected to great flow speed changes in the two suddenly-changed gaps, and therefore the turbulence phenomenon occurs, energy losses are caused, splashing movement is effectively stopped, and the oil drops are prevented from flying out.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a lockstitch sewing machine for cloth sewing. Background technique [0002] Lockstitch sewing 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 mutual cooperation of the cloth teeth and the shuttle wheel makes the upper thread and the lower thread interweave on the sewing material, thus completing the track sewing of the material. [0003] Among them, inside the machine head of the lockstitch sewing machine, the sewing needle mechanism is generally driven by a high-speed runner, so as to achieve the effect of fast sewing. For the rotating parts of the shaft wheel, the method of dripping liquid lubricating oil is mostly used to give Its lubricating anti-wear, in the prior art, the way of dripping oil of the rotating parts, as the manual attached figure 1 As ...

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
