Yarn carrying spindle for controlling bobbin pay-off tension through magnetic damping for knitting machine

Abstract

The invention discloses a yarn carrying spindle for controlling bobbin pay-off tension through magnetic damping for a knitting machine, and belongs to the yarn carrying spindle for controlling the bobbin pay-off tension through the magnetic damping. The yarn carrying spindle comprises a tension pay-off mechanism and a yarn outlet mechanism. The yarn outlet mechanism is fixedly installed at the upper end of one side of the tension pay-off mechanism. The tension pay-off mechanism comprises a base, a magnetic damper, a bearing flange, a mandrel, a sheath, a gasket, a volute spiral spring, a bobbin base, a bobbin, a bobbin pin shaft and a bobbin buckle. The yarn outlet mechanism comprises a vertical rod, a yarn outlet blocking rod, a third wheel shaft, a third wheel, a bearing sleeve, a rotating shaft, a yarn outlet wheel support, a yarn outlet wheel shaft, a yarn outlet wheel and a yarn outlet swing head; one side of the vertical rod is provided with the yarn outlet blocking rod, and thevertical rod is provided with the third wheel; the rotating shaft is installed at the top of the vertical rod and provided with the yarn outlet wheel support; and the yarn outlet wheel and the yarn outlet swing head are installed on the yarn outlet wheel support. The yarn carrying spindle has the advantages that manpower is saved, quality and efficiency are improved, product stability is guaranteed, and the large stroke, constant tension and even knitting pitch of a special knitting machine are achieved.

Description

technical field [0001] The invention relates to a yarn-carrying spindle for a braiding machine, in particular to a yarn-carrying spindle for a braiding machine that uses magnetic damping to control the pay-off tension of a bobbin. Background technique [0002] At present, when many knitting machines weave special fiber materials, they use ordinary spindles to run and weave on the knitting machine. The bobbin carrying spindles is installed vertically. The particularity of the fiber material has high performance requirements for the carrying spindle, including the controllability of the pay-off tension, large stroke, and the stability of the pay-off tension. [0003] Figure 4 The middle is a schematic diagram of the structure of the existing Pu Neng carrying spindle, including: the spindle rod (3-1), the bobbin (3-2), the thread pendant (3-3), the bobbin shaft (3-4), the middle porcelain eye ( 3-5), the line drop porcelain eye (3-6), the outlet porcelain eye (3-7), the brake...
