A needle seat device for quilt function shock absorption and noise reduction

Abstract

The invention relates to the technical field of sewing machine equipment, in particular to a needle base device used for vibration decreasing and noise reduction of a quilt sewing machine. The deviceincludes a needle rod base, a needle cylinder and a connection rod; the lower surface of the needle rod base is provided with the needle cylinder and an annular ultraviolet bactericidal lamp, a liquidstorage chamber is formed in the needle cylinder, a limiting ring is arranged below the liquid storage chamber, the lower surface of the limiting ring is provided with a rubber body and the rubber body is connected with the side wall of the middle of the connection rod in a sleeving mode; the side wall of the middle of the connection rod is provided with a liquid inlet, a liquid channel communicated with the liquid inlet is formed in the connection rod, the bottom surface of the connection rod is provided with a liquid outlet communicated with the liquid channel, and the bottom of the connection rod is fixedly provided with a metal needle; the lower side wall of the needle cylinder is connected with a presser foot sleeve matched with a fixing bolt in a sleeving mode, and the side wall ofthe presser foot sleeve is fixedly provided with a presser foot. The needle base device solves the problems that the needle base is poor in vibration decreasing effect and large in noise, metal needles are easy to break off, the broken metal needles are easily left in a cotton quilt, and potential safety hazards exist.

Description

technical field [0001] The invention relates to the technical field of quilting machine equipment, in particular to a needle seat device for quilting functions of shock absorption and noise reduction. Background technique [0002] Quilting machine is a kind of quilting machine, which is a textile machine used to sew linear patterns on mattresses, bedspreads, quilts, etc. The predecessor of the quilting machine is the quilting machine, which is similar to but opposite to the principle of the sewing machine. The quilting machine includes equal length ascending (descending) supports independently constructed to move up and down by independent operating rods; multiple needles mounted on ascending (descending) supports, mounted under ascending (descending) supports The guide member is provided with a guide hole, and the needle support member carrying the machine needle is fixed on the ascending (descending) support member through the guide hole. Each support rod is provided wit...
