Lifting transmission device of sewing machine rack

Abstract

The invention relates to the technical field of sewing machine equipment, in particular to a lifting transmission device of a sewing machine rack, which comprises a bottom plate, a lifting adjusting mechanism, a telescopic bedplate, two bottom frames and two telescopic adjusting mechanisms, the two bottom frames are arranged at an interval, and the two sides of the bottom plate are respectively connected with the outer walls of the two bottom frames; the lifting adjusting mechanisms are installed at the top of the bottom plate, the telescopic table plate is arranged at the top end of the lifting adjusting mechanisms, and the two telescopic adjusting mechanisms are arranged on the two bottom frames correspondingly and are symmetrically arranged. The situation that lifting adjustment cannot be carried out when one driving structure is damaged is avoided, meanwhile, the production cost is saved, when parts in the driving assembly are damaged, the height of the telescopic platen can be manually adjusted, and great convenience is achieved.

Description

technical field [0001] The invention relates to the technical field of sewing machine equipment, in particular to a lifting transmission device for a sewing machine frame. Background technique [0002] Industrial sewing machines are usually referred to as industrial sewing machines. They are special equipment for sewing workpieces in the sewing industry and related industrial sectors. Taking the automobile production industry as an example, they are used to sew automotive interior parts such as seat cushion covers, seat covers, etc. Take the clothing production industry as an example, it is used to sew shoes and hats, clothing and bedding products including bedding, etc. [0003] The lifting of the existing sewing machine frame generally adopts an automatic adjustment method, and two driving structures are used to drive the left and right lifting inner sleeves of the sewing machine table to move synchronously and smoothly. Once one of the driving structures is damaged in thi...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a lifting transmission device for the sewing machine frame, to solve the above-mentioned background technology, which generally adopts an automatic adjustment method and uses two driving structures to drive The left and right lifting inner sleeves of the sewing machine table move synchronously and smoothly. Once one of the driving structures is damaged in this way, the lifting adjustment cannot be performed, which is very inconvenient.
