Abstract

The invention discloses a sewing machine and an anti-layer-staggering device thereof. The sewing machine comprises a sewing table and an air suction device arranged at the bottom of the sewing table.An air suction hole is formed in the sewing table, and the air suction device sucks air through the air suction hole to control friction force between lower-layer cloth and the sewing table. When double-layer cloth is sewn, the cloth is pressed on a faller through a presser foot of the sewing machine, the cloth is controlled to move forwards through the movement of feed dogs, the air suction device sucks the lower-layer cloth through the air suction hole, the friction force between the lower-layer cloth and the sewing table can be increased, under the influence of the friction force, the lower-layer cloth is in a slightly-tensioned state, the lower-layer cloth is tensioned, upper-layer cloth is in a loosened state, the feeding efficiency of the lower-layer cloth can be reduced, thus, the upper-layer cloth and the lower-layer cloth have the same feeding efficiency, and the condition of layer staggering of the cloth is avoided.

Description

technical field [0001] The invention relates to the technical field of sewing, in particular to a sewing machine and an anti-stacking layer device thereof. Background technique [0002] When the current sewing machine is sewing double-layer fabrics, since the lower fabric is in direct contact with the teeth of the feed dog, the upper fabric is driven by the lower fabric, so the feeding efficiency of the lower fabric is higher than that of the upper fabric, so it is very easy to The phenomenon of upper and lower layers. If the layering is serious when the fabric is sewn, it may even cause the fabric to be scrapped, especially for some high-end clothing, it is necessary to avoid the phenomenon of layering. [0003] Therefore, how to prevent the double-layer fabric from being staggered during sewing is a technical problem that those skilled in the art need to solve at present. Contents of the invention [0004] In view of this, an object of the present invention is to provi...
