Take-up device for sewing thread production

Abstract

The utility model relates to the technical field of sewing thread automatic winding, and discloses a sewing thread production take-up device which comprises a base, a box body is fixedly arranged on the upper end face of the base, an opening is formed in the left side of the box body, and a box door is installed on the right end face of the box body. By means of the arrangement, when a sewing thread is in a tightened state, a first contraction spring does not contract, when the sewing thread is too loose, the first contraction spring can drive a first supporting plate, a first mounting rod and a first pulley to contract, and therefore the sewing thread can be tightened, and the upper tension adjusting device and the lower tension adjusting device can be adjusted. When the position of the sewing thread on the lower tensioning force adjusting device is too loose, a second contraction spring can rebound, the distance between a second supporting plate and a second fixing plate is reduced, the sewing thread is prevented from falling off, the effect of adjusting the tensioning force of the sewing thread is achieved, and the tensioning degree of the sewing thread is automatically adjusted; and the tensioning force does not need to be adjusted manually.
