Spinning bobbin

Abstract

The invention discloses a spinning bobbin which comprises a bobbin body and two annular bobbin covers. The bobbin body comprises an aluminum alloy outer pipe and a stainless steel inner pipe sleeved in the outer pipe. A plastic flexible strip is fixed on each annular bobbin cover. A plurality of location grooves in the length direction are evenly distributed in the stainless steel inner pipe in the circumferential direction, and protruding strips are arranged on the aluminum alloy outer pipe correspondingly. The number of the plastic flexible strips is at least four. Each annular bobbin cover is a phenolic aldehyde plastic pipe cover. Due to the fact that the plastic flexible strips are installed on the bobbin covers, the problem of knotting of a spinning machine in the spinning process is solved, and working efficiency and product quality are improved. The aluminum alloy outer pipe is supported by the stainless steel inner pipe, so that the aluminum alloy outer pipe is not easy to deform, yarn covering production stability is ensured, and bobbin service life is prolonged.

Description

technical field [0001] The invention relates to a textile bobbin, which belongs to the field of textiles. Background technique [0002] The textile industry is one of the traditional industries in our country. In the textile production process, the bobbin is an indispensable part. The shape of the bobbin is generally two circular tube covers clamping a cylindrical tube body. During the rotation of the bobbin, the yarn can be wound or the wound yarn can be released. [0003] Since the textile machine does not extract the thread at a fixed speed during the production process, and the high-speed rotating bobbin has inertia, the rotating speed of the bobbin is not always the same as the speed at which the textile machine collects the thread, so it is likely that the thread The situation of knotting not only affects the production efficiency, but also reduces the quality of textiles. In addition, because the inner core of the existing bobbin is made of ordinary plastic, the mat...

Problems solved by technology

[0003] Since the textile machine does not extract the thread at a fixed speed during the production process, and the high-speed rotating bobbin has inertia, the rotating speed of the bobbin is not always the same as the speed at which the textile machine collects the thread, so it is likely that the thread The situation of knotting not only affects the production efficiency, but also reduces the quality of textiles

In addition, because the inner core of the existing bobbin is made of ordinary plastic, the material is relatively soft, so the inner core of the bobbin is not wear-resistant, and it is easy to deform after long-term use, which will cause the bobbin to rotate eccentrically during rotation, which further increases the The wear of the inner core of the bobbin affects the service life of the bobbin
