High-speed automatic tucker for industrial sewing machine

Abstract

The invention discloses a high-speed automatic tucker for an industrial sewing machine. The high-speed automatic tucker adopts the structure that a pinion is fixedly arranged on a transmission shaft; a gearwheel meshed with the pinion is arranged above the pinion, and is fixedly arranged on a first shaft; adjusting eccentric wheels (namely a first adjusting eccentric wheel and a second adjusting eccentric wheel) are fixedly arranged at the tail ends of both the first shaft and the transmission shaft respectively; the first adjusting eccentric wheel is connected to the bottom end of a steering crank through a first eccentric connecting rod; the second adjusting eccentric wheel is connected to a swinging frame connecting rod through a second eccentric connecting rod; the top end of the swinging frame connecting rod is fixedly arranged on a second shaft; the steering crank sleeves the second shaft in a rotatable manner; a shovel piece mounting shaft connecting column sleeves the bottom of the swinging frame connecting rod in a rotatable manner; a shovel piece mounting shaft is fixedly arranged at one end of the shovel piece mounting shaft connecting column; a feeding shovel piece is mounted on the shovel piece mounting shaft; the other end of the shovel piece mounting shaft connecting column is connected to the top end of the steering crank through a connecting rod. The high-speed automatic tucker can be mounted on the industrial sewing machine, can use a motor of the sewing machine as a power source, and can utilize double spring shovel pieces to closely clamp a fabric to realize material feeding of a presser foot, so that the pleating stability, the sewing efficiency and the sewing speed are improved.

Description

Technical field [0001] The invention relates to a pleating device, in particular to a high-speed automatic pleating device of an industrial sewing machine. Background technique [0002] The pleating device is usually installed on the sewing machine to cooperate with the sewing machine and used for sewing pleated lace of clothing, bedspreads, curtains and sofa covers. The existing pleating device usually includes a transmission mechanism, a swing rod and a feeding blade. The swing rod converts the rotation of the transmission mechanism into a reciprocating motion of the feeding blade. The feeding blade relies on friction to feed material to the sewing machine, so that the cloth is continuously folded. However, the existing pleating device has disadvantages such as unstable operation, low sewing efficiency, and inconvenient adjustment. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a high-speed automatic pleating device f...
