Automatic material pouring device of food frying machines

An automatic material pouring device of food frying machines, comprising:

• a machine body, including at least a support body;
• a food frying pot, including at least a hollow outer case body mounted on the support body, in which the outer case body is pivotally installed with a servo motor which is used to memorize an adding-material angle in order to control the operating position of the outer case body, and the outer case body is recessively installed with a notch from the outside toward the inside, and the interior of the notch is pivotally installed with an inner frying pot whose bottom is pivotally installed with an inner pot motor;
• a material adding device, including a base fixedly installed on the support body, in which a movable seat is installed on the base, and a driven gear is provided on the outside of the movable seat, and the driven gear meshes with a driving gear together such that the driving gear can drive the driven gear to move along with the movable seat, and in which at least one material placement box is placed on the movable seat and is made of a metal material that can be attracted by magnetic force, and the base also includes a feeding cylinder and an attracting device, and the feeding cylinder and the attracting device are conjunctively assembled;
• and
• a master controller, respectively connected to the servo motor, the inner pot motor, the driving gear, the feeding cylinder as well as the attracting device,
• wherein the exterior of the outer case body is installed with a position difference sensing device connected to the master controller and applied to sense the start and end positions of the rotation of the outer case body in order to limit the outer case body to operate in this safe angle range, and the position difference sensing device also respectively includes a start position determination block, an end position determination block, a start sensing terminal and an end sensing terminal, in which the start position determination block and the end position determination block are respectively installed on a surface of the exterior of the outer case body in opposition to the support body, and the start sensing terminal and the end sensing terminal are respectively installed on a surface of the exterior of the support body in opposition to the outer case body, such that, when the outer case body rotates, if the start sensing terminal detects the start position determination block, or otherwise the end sensing terminal detects the end position determination block, then the master controller controls the servo motor to stop the rotation operation.
