Treatment-free rubber roll for air vortex spinning

Abstract

The invention relates to a treatment-free rubber roll for air vortex spinning, in particular to a rubber roll for drafting yarns on an air vortex spinning machine. The rubber roll comprises a roll body, wherein the roll body is a circular rubber short pipe. The rubber roll is characterized in that an aluminum bushing is arranged in the roll body, and is tightly matched with the roll body. The diameter of the external circumference of a middle section of the roll body is greater than the diameters of the external circumferences of two end sections of the roll body, so that circumferential steps can be formed on the external circumferences of the two ends of the roll body. A binding force between the treatment-free rubber roll for the air vortex spinning and a bearing is high, and the treatment-free rubber roll is easy to process, low in manufacturing cost and long in service life.

Description

technical field [0001] The invention relates to a treatment-free rubber roller for vortex spinning. Specifically, it is the rubber roller used to draft the yarn on the vortex spinning machine. Background technique [0002] It is known in the spinning industry that the cots used to draft the yarn on the turbo spinning machine are all traditional cots. This traditional cot is a pure rubber product, and the inner diameter and outer circle of its full length are equal. In order to ensure the tight fit between the rubber roller and the bearing, it is required that the rubber roller is set on the bearing housing in an interference shape. If the outer diameter of the bearing is 19 mm, the inner diameter of the rubber roller is required to be 18 mm. Since the rubber roller is set on the bearing shell in an interference shape, the hardness of the rubber roller can be increased through the tension of the rubber roller (usually by 1~2 degrees). However, as the tension of the rubber ...

Problems solved by technology

Therefore, the service life of traditional rubber rollers is short

Because the traditional rubber roller is made of pure rubber, the bonding force between it and the bearing is not strong, and it is easy to escape from the bearing.

And because the traditional rubber roller is a pure rubber product, when it is set on the bearing, it is easy to bulge and deform, and it needs to go through the rounding process to flatten the bulge. The production process is many and the production cost is high.
