Embodiment Construction
[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] In the brick making machine, when each eccentric wheel rotates at a constant speed, the corresponding driving motor needs to output the torque T to satisfy the following formula:
[0047] T=F2×OO’+B (3)
[0048] Among them, F2 is the gravity component in the rotation direction of the eccentric wheel, OO' is the eccentricity, and B is the friction force of the transmission mechanism. In order to make the horizontal forces of the two eccentric wheels in the same group of exciting force units in the vibrating box of the brick making machine cancel each other out, it is necessary to ensure that...

Embodiments of the present invention provide a method, system, device, and computer-readable storage medium for identifying the origin of an eccentric wheel. The method includes: controlling the servo motor to drive the eccentric wheel to rotate to multiple preset positions in sequence; The preset position is the starting point, and the servo motor is controlled to drive the eccentric wheel to rotate clockwise and counterclockwise from the static state at the starting point, and obtain the clockwise and counterclockwise directions of the eccentric wheel Rotate the displacement difference of the preset time; compare the magnitude of the displacement difference in two directions under multiple starting points, and use the starting point corresponding to the smallest displacement difference as the origin position of the eccentric wheel. In the embodiment of the present invention, by comparing the position difference of the eccentric wheel rotating clockwise and counterclockwise at the same time at multiple preset positions, the origin position of the eccentric wheel can be obtained without a proximity switch, which improves the accuracy of the origin, thereby greatly improving brick making reliability of machine operation.
Description
technical field [0001] Embodiments of the present invention relate to the field of brick making machines, and more specifically, relate to a method, system, device, and computer-readable storage medium for identifying the origin of an eccentric wheel. Background technique [0002] On the brick making machine equipment, the vibrating box is the core component that determines the molding of the pressed brick. The vibrating box presses concrete and other brick-making materials into shape through the exciting force of high-frequency vibration in the vertical direction. Usually, there are two or four eccentric wheels rotating synchronously in the vibrating box. During the high-speed rotation of the eccentric wheels, the inertial forces in the horizontal direction cancel each other out, and the inertial forces in the vertical direction are superimposed on each other and transmitted to the mold motherboard to form a shock. Vibration force. [0003] Such as figure 1 As shown, eve...
