Description

Technical Field

[0001] The utility model relates to the technical field of shaft paralleling machines, in particular to a shaft paralleling machine protection device. Background Art

[0002] The warp-winding machine is a device used in the warp-winding process. It consists of a pulp shaft frame and a machine head. The pneumatic warp tension control device on the pulp shaft frame can automatically keep the unwinding tension of each pulp shaft warp constant and uniform. The winding mechanism of the machine head winds the warp at a constant speed and constant tension, and at the same time applies winding pressure to the weaving shaft through a pressure roller in an air pressure manner. Some warp-winding machines are also equipped with a twisting foil between the machine head and the pulp shaft frame for warp twisting. When the warp-winding machine rotates at high speed, the tension and pressure of the silk thread will increase. When the silk thread breaks, it often produces splashing and causes irreversible damage to nearby personnel. Therefore, equipment protection devices are required to ensure safety.
