Cotton fiber self-circulation cutting device and cutting method

Abstract

The invention discloses a cotton fiber self-circulation continuous cutting device, and the device comprises an electric stirrer, a slurry tank, a stator cutter, a machine base, a cutter feeding and retracting support, a cutter feeding and retracting control mechanism, a rotor cutter driving mechanism, a rotor cutter and a backflow pipe. An output shaft of the electric stirrer extends into the slurry tank and is provided with stirring blades at the end part; cutter mounting holes are formed in positions, opposite to the stirring blades, of the slurry tank; the stator cutter is fixedly mounted on the inner circumference of the cutter mounting hole; the base is correspondingly positioned on one side of the slurry tank; the cutter feeding and retracting support is slidably mounted on the machine base in the direction parallel to the axis of the cutter mounting hole. The rotor cutter is matched and meshed with the stator cutter; one end of the return pipe is communicated with the cutter mounting hole, and the other end is bent and extends into the slurry tank. The invention discloses a cotton fiber self-circulation continuous cutting device and a cutting method. A stator cutter and a rotor cutter jointly realize cutting treatment on long cotton pulp fibers; in addition, continuous self-circulation cutting treatment of the slurry can be achieved through the arrangement of the backflow pipe, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of papermaking and pulping equipment, in particular to a cotton fiber self-circulating cutting device and a cutting method. Background technique [0002] Cotton is divided into long-staple cotton and fine-staple cotton. The length of fine-staple cotton is generally 25-31mm, and the length of long-staple cotton is more than 33mm. Because of its good fiber quality, it is an important raw material for producing banknote paper. [0003] However, due to the long length of cotton fiber, it cannot be directly used for the production of banknote paper through low-consistency beating. It needs to be pre-cut by special equipment to a length of 3-5mm, and then continuously low-consistency beating. The cotton fiber cutting device in the prior art cannot self-circulate, and the work process is cumbersome, which affects work efficiency. [0004] Therefore, how to provide a cotton fiber self-circulating cutting device and...
