Document Type and Number:
WIPO Patent Application WO/2022/091468
Kind Code:
A1
Abstract:
Provided is a technology for constantly controlling a cutter blade pressing force even in a case of adopting a configuration for improving manufacturing efficiency of pellets. In this resin cutting device, a control unit for controlling a cutter blade pressing force is configured to variably control the rotation speed of a rotary shaft attached to a cutter head, the magnitude of a rotary shaft advancement force Ff, and the magnitude of a rotary shaft retreat force Fb, respectively so that the cutter blade pressing force becomes constant.
