Pay-off braking device for spindle of high-speed braiding machine

Abstract

The invention relates to a pay-off braking device for a spindle of a high-speed braiding machine and belongs to a spindle braking structure of a braiding machine. The pay-off braking device comprises a spool base, a braking claw and a connecting rod, wherein one end of the braking claw is pressed on a side wall of an inner circular groove under the spool base; the other end of the braking claw is connected with the connecting rod; the spool base has a shape of a disc; a hole is formed in the middle of the disc; cylinders are uniformly distributed on the circumference of the same circle center as the hole; the inner circular groove is arranged under the disc; raised platforms are arrayed on an inner wall of the inner circular groove; the braking claw is L-shaped; the front end of the braking claw is pawl-shaped and moves in the inner circular groove under the spool base; a small hole is formed at a bent part of the braking claw and is sleeved on a pivot shaft; and the rear end of the braking claw is in sliding connection with the connecting rod. The pay-off braking device has the advantages that: a pay-off line is controlled by the pay-off braking device in a point contact way; the spindle pay-off is easy and flexible; the abrasion is small; the braking is accurate and gapless; a transmission part is simple in structure, low in cost, high in flexibility and long in service life; a rough yarn and a spun yarn are compatible; the yarn is free from being broken; and the braiding is uniform.

Description

technical field [0001] The invention relates to a spindle brake structure of a braiding machine, in particular to a spindle pay-off brake device for a high-speed braiding machine. Background technique [0002] The high knitting machine spindle pay-off braking device that uses on the present braiding machine has top pin upward braking type and ratchet depressing type. [0003] exist figure 1 Among them, the structure of the lift pin upward braking type is: there is a faceplate (1-2) on the spindle body (1-1) of the lift pin upward brake type, and the faceplate (1-2) is sleeved on the bobbin shaft (1-2). 3) On the top, the bobbin shaft (1-3) is connected with the spindle body (1-1), and the spindle body (1-1) is provided with an ejector pin (1-4). The upper end of the ejector pin (1-4) is placed in the lower groove of the faceplate (1-2), and the ingot body (1-1) is covered with a wire pendant (1-5), and the wire pendant (1-5) and the ejector pin (1-4 ) in the horizontal ax...
