Spinning yarn bobbin with long service life

Abstract

The invention discloses a spinning yarn bobbin with the long service life. The spinning yarn bobbin comprises a top disc, a bottom disc and a bobbin body. The bobbin body is cylindrical and comprises a bobbin outer wall and a bobbin inner wall. Transition faces are arranged at the two ends of the bobbin outer wall, and the surfaces of the transition faces are of an arc downward-concave structure. A cylindrical hollow cavity is formed in the bobbin inner wall, and a plurality of protruding rings are linearly arranged on the surface of the bobbin outer wall in the horizontal direction. Ball grooves are symmetrically formed in the inner side of the bobbin inner wall, and balls are arranged in the ball grooves and clamped in the ball grooves. Holes with the diameters being smaller than those of the ball grooves are formed in the positions, corresponding to the ball grooves, of the bobbin inner wall.According to the spinning yarn bobbin, the ball grooves with the balls are formed in the bobbin inner wall, so that the yarn bobbin is more balanced in rotation, direction friction of the bobbin inner wall and a rotating shaft is avoided, friction damage of the yarn bobbin is avoided, and the service life of the yarn bobbin is prolonged; the bobbin body is connected with the top disc and the bottom disc through pipe fittings, and the yarn bobbin can be conveniently dismounted and replaced.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a textile yarn bobbin with long service life. Background technique [0002] The textile industry is a traditional industry in our country. Textile machinery has also developed along with the textile industry. In the textile industry, yarn wrapping machines for surface coating of yarns are widely used. Yarn wrapping machines are equipped with yarn wrapping machines Tube and the side plate to prevent the yarn from falling off from the bobbin, but the existing bobbin is made of aluminum alloy material, so when the surface of the bobbin or the side plate is damaged, the whole sand tube will be discarded, so that It causes a waste of resources. At the same time, the side disks on both sides of the bobbin are vertical, which reduces the amount of yarn that can be wound by the bobbin. In addition, the surface of the bobbin is generally flat, so that the bobbin is winding It is easy to ...

[0002] The textile industry is a traditional industry in our country. Textile machinery has also developed along with the textile industry. In the textile industry, yarn covering machines for surface coating of yarns are widely used. Yarn covering machines are equipped with yarns for winding yarns. The tube and the side disk to prevent the yarn from falling off from the bobbin, but the existing bobbin is made of aluminum alloy material, so when the surface of the bobbin or the side disk is damaged, the whole sand tube will be discarded, so that It causes a waste of resources. At the same time, the side disks on both sides of the bobbin are vertical, which reduces the amount of yarn that can be wound on the bobbin. Moreover, the surface of the bobbin is generally smooth, so that the bobbin is winding It is easy to cause the yarn to intertwine in the horizontal direction of the bobbin, which will bring inconvenience to the later use, and the inner wall of the bobbin and the rotating shaft will constantly rub against each other during work, so that the service life of the bobbin will be shortened and it will be easily damaged.
