Mixing and whipping device based on a piston crank-slider mechanism

The device for mixing and whipping based on a piston crank-slider mechanism operates in the rotational mode of the drive link. With minimal engine power, the piston with the slider rises up, the connecting rod slows down, and after bypassing the engine shaft (crank), the connecting rod and the piston with the slider moves downwards at an accelerated rate. The force of the piston's interaction with the liquid was measured by a CALL DYLY-103 force load cell, which was integrated into the slider and connected to the ZET 058 strain gauge station and then to a computer. Using the ZETLAB software, oscillograms of the forces acting on the slider were obtained for various modes of operation of the prototype mixing-whipping device. According to the obtained oscillograms of forces, the maximum forces of interaction of the piston with the liquid for various modes were estimated. The linear acceleration of the slider was measured using a ZET 7052-N digital accelerometer, which is connected to a computer via the ZET 7076 interface. Using the filtering program, the linear velocity of the slider was obtained, which was recalculated through the transfer function of the device into the angular velocity of the crank.
