Cloth feeding mechanism of embroidery machine

Abstract

The invention discloses a cloth feeding mechanism of an embroidery machine. The cloth feeding mechanism comprises a front cloth clamping roller set, a rear cloth clamping roller set, a left chain transmission mechanism and a right chain transmission mechanism, wherein the front cloth clamping roller set and the rear cloth clamping roller set are arranged in front of and at back of a machine head respectively; the left chain transmission mechanism and the right chain transmission mechanism are arranged on the left side and the right side of the machine head respectively; the left chain transmission mechanism comprises a first driven chain wheel, a first driving chain wheel and a first chain, the first driving chain wheel is driven by a first motor to rotate, the first motor is fixedly mounted on a vertical plate which is parallel with the first chain and spaced with the first chain by a certain distance, the first driven chain wheel is rotationally mounted on the vertical plate, and the vertical plate is driven by a linear drive device to move horizontally; the right chain transmission mechanism comprises a second driven chain wheel, a second driving chain wheel and a second chain, the second driving chain wheel is driven by a second motor to rotate, the second driven chain wheel is rotationally mounted on a rack of the embroidery machine, and a plurality of insertion needles are mounted on the outside of each chain link of the first chain and the second chain. The cloth feeding mechanism of the embroidery machine guarantees the flatness of cloth between the front cloth clamping roller set and the rear cloth clamping roller set, and the embroidery quality is improved.

Description

technical field [0001] The invention relates to an embroidery machine, in particular to a cloth feeding mechanism of the embroidery machine. Background technique [0002] There is a cloth feeding mechanism for an existing embroidery machine. The embroidery machine includes a machine head fixedly installed on the crossbeam of the embroidery machine. Several embroidery needles for embroidery are installed at the bottom of the machine head. The cloth feeding mechanism includes The front and rear cloth clamping roller sets on the front and rear sides of the machine head. The cloth roller set includes rear cloth rollers which are rotatably installed on the frame of the embroidery machine and arranged in pairs up and down. When working, the embroidery on the machine head is fed into the gap between the front cloth roller group and the rear cloth roller group. fabric for embroidery. [0003] The cloth feeding mechanism of this structure has the following defects in operation, tha...
