Soft water mixing machine based on crude oil and grease mixing process

The invention relates to the technical field of mixing machines, and discloses a soft water mixing machine based on a crude oil grease mixing process, which comprises a base, an outer barrel is fixedly connected to the side wall of the base, an inner barrel is rotatably connected to the inside of the outer barrel, a tensioner is arranged above the base, and a speed regulating assembly for regulating the rotating speed of the inner barrel is arranged above the base. The driving shaft rotates, the transmission part enables the rotating lead screw to generate extra rotation, the extra rotation of the rotating lead screw drives the nut round seat, the second rotating rod and the first rotating rod to move, and then the variable-pitch arc plate can be in the expansion and contraction state periodically. The diameter of the variable-pitch arc plate can be changed due to periodic expansion and contraction, and the variable-pitch arc plate can be periodically expanded and contracted, so that the inner barrel can bett
