Description

Technical Field

[0001] The invention belongs to the technical field of wall breaking machines, and in particular relates to an electric spindle for a double-shaft double-blade double-phase rotating wall breaking machine. Background Art

[0002] The wall breaking machine mainly drives the blade through the high-speed rotation of the motor to cut, crush and mix the objects. The blade is generally made of high-hardness stainless steel, and the shape design is relatively special, which can process objects from different angles. The motor speed is usually high, and the speed of some wall breaking machines can reach more than 20,000 revolutions per minute. When the motor drives the blade to rotate at high speed, the object is repeatedly cut and collided between the blade and the container wall, so that the cells are broken. From the existing technology, the common wall breaking machine spindle is a single-axis structure, and a separate motor drives the bearing to rotate. The blades are distributed on the bearing, but the single-axis wall breaking machine has low efficiency and poor stability, and there are often omissions in the wall breaking process. For this reason, we propose a dual-axis dual-blade disc dual-phase rotating wall breaking machine motor spindle.

[0003] It should be noted that the above content belongs to the scope of technical cognition of practical people and does not necessarily constitute prior art. Summary of the invention
