Problems solved by technology

[0002] The spun bobbin currently used in the market is movable on the pallet, and the unwinding of the bobbin belongs to the unclamping unwinding of the spun bobbin. When the spun yarn on the spinning machine starts to be wound, it is in the process of acceleration, and the yarn tension continues to increase. When the upper yarn is unwound to the last short section of yarn, the total gravity of the yarn on the spun bobbin and the spun bobbin is not enough to balance the yarn tension. Tension fluctuations from the unwinding point to the drum, causing yarn climbing, affecting the shape of the package, resulting in difficulties in subsequent warping and weaving

Abstract

The invention discloses a tray for fixing a ring bobbin of a bobbin winder. The tray comprises a supporting tube body and an expanding supporting assembly, wherein the bottom of the supporting tube body is fixedly connected to a circular tray, and the top end of the supporting tube body is detachably connected to a conical end head; and the expanding supporting assembly is arranged on the supporting tube body in a penetrating mode, and is assembled to be used for automatically supporting and fixing the ring bobbin connected to the supporting tube body in a sleeving mode. According to the invention, the expanding supporting assembly is arranged on the supporting tube body in a matched mode, and when the ring bobbin is nested in the supporting tube body on the tray for fixing the ring bobbin, the ring bobbin is automatically fixed by the expanding supporting assembly, so that the ring bobbin and the tray form a whole, total gravity is greater than the tension of the ring bobbins, and thering bobbin does not bounce, tension fluctuation from the bobbin bottom to a groove drum is eliminated, and cone yarn climbing is reduced; and meanwhile, multi-point supporting and fixing of the ringbobbin are achieved through the expanding supporting assembly, so that fixing stability of the ring bobbin is improved.

Description

technical field [0001] The invention relates to the technical field of a spinning bobbin fixing tray, in particular to a tray for fixing a spinning bobbin of a winding machine. Background technique [0002] The spun bobbin currently used in the market is movable on the pallet, and the unwinding of the bobbin belongs to the unclamping unwinding of the spun bobbin. When the spun yarn on the spinning machine starts to be wound, it is in the process of acceleration, and the yarn tension continues to increase. When the yarn on the yarn is unwound to the last short section of yarn, the total gravity of the yarn on the spun bobbin and the spun bobbin is not enough to balance with the yarn tension. Tension fluctuations from the unwinding position to the groove drum cause yarn climbing, affecting the shape of the package yarn, resulting in difficulties in subsequent warping and weaving. Contents of the invention [0003] The object of the present invention is to provide a tray for...
