Abstract

This invention discloses one synchronous traction device of industrial sewing machines fabric, it includes stent installed on the table and driving wheel of machine heads, the point is that install one follower wheel with transmission gears at the back of driving wheel, the follower wheel is connected with driving wheel by belt; one shaft is installed at one side of the gear of driven wheel, at one side of the shaft install a differential gear and an active roller at the other side, the steering Gear is installed between the gear of driven wheel and differential gear, the two gear in between match; one support bar is installed on the double-bearing, its top connect with one connecting rod, at one side the connecting rod connect without fix with clutch control rod, at the other side it connect with friction roll by pin, in order to make the friction roll work closely with active roll one tension spring is installed between the double-bearing and connecting rod. This invention has the traits of new structure, reasonable design, good synchronous effect, it not only improves the quality of sewing fabric, but also lowered the cost of production and widely to be installed to use in the industrial sewing machines of flake sewing fabric.

Description

Technical field [0001] The invention relates to the technical field of industrial sewing machines, in particular to a sheet fabric traction mechanism which is installed on the working table of the sewing machine and works synchronously with the sewing machine. Background technique [0002] There are many types of industrial sewing machines, and they all have different sewing effects. At present, the most commonly used industrial sewing machines for sewing flat fabric pieces, when sewing fabrics such as building safety fences, plastic woven bags, and tarpaulins, because these industrial sewing machines do not have corresponding fabric traction mechanisms, the above-mentioned fabrics cannot be sewn. Usually, two people are required to cooperate with the operation. One person operates the machine and feeds the material, while another person pulls the fabric behind to ensure that the fabric can be sewn as required. Since this industrial sewing machine does not have a correspon...
