Bobbin for spinning frame

Abstract

The invention telates to a inserted bobbin for spinning frame locating at inner surface of the bobbin or contacting place of the spindle. Bushing is an alloy consisting of copper, nickel and zinc with content of 10-80% wt respectively. Polytetrafluoroethylene is used for coating inner surface of the bushing. In the circle of the bushing, a concavo-convex surface is formed to provide the spindle with a groove. Racing phenomena will not occur in the contacting part between the bobbin and the bushing, between the bushing and the spindle, upon tatating the bobbin. Revolving force can be transmitted to the bobbin when rotating with high speed. The invention relates to the bobbin for spinning frame with bushing inserted into inner surface of the bobbin. The bushing, the bobbin and the spindle is in a tightly bonding state when rotating with high speed to prevent racing, centrifugal error of bobbin axis and floating phenomena of the bobbin. Fault rate of processing is reduced and thickness of the bobbin is increased. Due to the solid materials used in the bushing, the transverse strength of the bobbin is enhanced.

Description

technical field [0001] The present invention relates to a bobbin for spinning frame, and more specifically relates to a bushing inserted around the spindle tip in the bobbin for spinning frame, characterized in that it is inserted with 10 to 80% by weight Copper, 10-80% by weight of nickel and 10-80% by weight of zinc are alloyed, the inner surface is coated with tetrafluoroethylene, and the thickness is a bobbin for a worsted spinning machine with a bushing below 0.3mm. Background technique [0002] The worsted spinning process is the process of threading the roving (roving) produced in the group spinning process according to the required thickness and then twisting the yarn to make the thread. It is the final process of weaving that has the greatest impact on product quality or production efficiency than any other process. craft. [0003] The most widely used spinning machine in the worsted spinning process is the ring spinning frame. In the ring spinning frame, the bobbi...

Problems solved by technology

[0011] When the bobbin floats out like this, the side-to-side shaking of the front end of the bobbin is increased, which cannot meet the requirements of the latest spinning machine (vibration range of the front end of the bobbin ≤ 0.25mm), and problems arise in the production of high-quality yarns.
