Title:
CHIP CRUSHER AND METHOD FOR CUTTING CHIPS
Document Type and Number:
WIPO Patent Application WO/2023/139830
Kind Code:
A1
Abstract:
[Problem] To provide a chip crusher and a method for cutting chips with which it is possible to prevent an emergency stop and/or a breakage accident due to chip clogging, and to resolve the problem of time loss and work efficiency reduction due to the work of removing clogging chips. [Solution] A rotary blade 11 is configured by alternately fitting large-diameter blades 29 and small-diameter blades 31 by insertion on a drive shaft 27 that is rotationally driven by a motor. To a casing 25 of a cutting part 15 by which the rotary blade 11 is rotatably supported, a fixed blade 13 that is engaged with the rotary blade 11 is fixed. As the large-diameter blades 29, three types of large-diameter blades 29A, 29B, 29C with different phases are prepared and combined into an array pattern. Due to the displacement in phase, even when a large number of chips 21, 21, ... are dropped at once in a lump, the load is distributed because the row of blade parts 29d, 29d, ... facing upward is thinned out. In addition, the fixed blade 13 for general purposes can be utilized as it is. Furthermore, the array pattern can be optimized in accordance with the conditions of the chips 21.
