Towel embroidery machine head with single cam and three connecting rods

Abstract

The invention discloses a towel embroidery machine head with a single cam and three connecting rods. The head comprises a head shell, wherein a towel needle up and down driving device, a presser foot up and down driving device and a needle mouth up and down driving device are respectively installed in the head shell and are respectively provided with a towel needle connecting rod, a presser foot connecting rod and a needle mouth connecting rod; the towel needle connecting rod, the presser foot connecting rod and the needle mouth connecting rod are connected with bearings; the bearings are connected with a same cam in a matching manner; a towel needle cam path ring, a presser foot cam path ring and a needle mouth cam path ring are axially arranged on the cam. The towel embroidery machine head has the beneficial effects that the bearings connected to the towel needle connecting rod, the presser foot connecting rod and the needle mouth connecting rod are simultaneously matched with the same cam and the towel needle cam path ring, the presser foot cam path ring and the needle mouth cam path ring are axially arranged on the cam, thus achieving synchronous drive of the towel needle connecting rod, the presser foot connecting rod and the needle mouth connecting rod; the cam has the technical effects of three traditional cams, thus greatly reducing the axial dimension of the towel embroidery machine head.

Description

technical field [0001] The invention relates to a towel embroidery machine head, in particular to a towel embroidery machine head with a single cam and three links. Background technique [0002] At present, towel embroidery is a special type of embroidery in the embroidery machine industry. The uneven axial size of the towel embroidery machine head affects the equipment cost, and also directly determines the number of embroidery machine heads per unit length. How to reduce the towel The axial dimension of the embroidery machine head has always been the research object of those skilled in the art. In the prior art, the head of a towel embroidery machine generally includes three sets of devices, such as the up and down driving device of the towel needle, the up and down driving device of the presser foot, and the up and down driving device of the needle nozzle. These three sets of devices are all driven by independent connecting rods, and the connecting rods are connected The...
