In one embodiment of the present invention, a spraying device 130 is provided on one side of the table 110 for spraying batter onto the upper portion of the griddle 120. Specifically, the dough apparatus 130 includes a batter spout 131 of hollow structure. One end of the batter nozzle 131 near the flattening mechanism 140 is fixed to a second rotating shaft which extends downward through the console 110 and is fixedly connected to the output shaft of the second motor. The second motor is fixed at the lower part of the operating platform 110, and is used for driving the batter nozzle 131 to rotate around the axial direction of the second rotating shaft and the side of the self-spraying surface device 130 to the side of the flattening device mechanism 140. The second motor is electrically connected to the automatic electric control unit, and when the griddle 120 is in a rotating state, the automatic electric control unit controls the second motor to drive the batter nozzle 131 to rotate from the side of the batter nozzle 130 to the side of the flattening device 140, and the batter flows to the upper part of the griddle 120 through the batter nozzle 131. The end of the batter nozzle 131 remote from the flattening mechanism 140 is provided with a batter nozzle 132 through which batter can flow out. Wherein the batter nozzle 131 and the batter nozzle 132 are positioned above the griddle 120. Thus, the batter flows through the batter nozzle 131 and the batter nozzle 132 can fall onto the upper portion of the griddle 120. When the amount of batter dropped onto the upper portion of the griddle 120 is a preset amount, the batter spout 131 is rotated. Here, the rotation of the batter nozzle 131 means that the batter nozzle 131 rotates from the side of the flattening device 140 toward the side of the surface spraying device 130, so that the batter nozzle 131 is finally located on the side of the surface spraying device 130.

In one embodiment of the present invention, the side of the table 110 adjacent to the side having the spraying device 130 is provided with a spreader mechanism 140 for spreading the batter on the upper portion of the flat 120. Specifically, the flattening device mechanism 140 includes a fixing bracket 141 with a long strip structure, a flattening shovel 142 with a square plate structure is fixed on the fixing bracket 141, and the plane of the flattening shovel 142 is perpendicular to the plane of the griddle 120. One end of the fixing support 141, which is far away from the spraying surface device 130, is fixed on a third rotating shaft, and the third rotating shaft penetrates through the operation table 110, extends downwards and is fixedly connected with an output shaft of the third motor. The third motor is fixed to the lower portion of the operating platform 110, and is used for driving the fixing bracket 141 to rotate around the axial direction of the third rotating shaft from the side of the flattening device to the opposite side of the spraying device 130, so as to drive the flattening shovel 142 to rotate. The third motor is electrically connected with the automatic control unit of the electric appliance. When the griddle 120 maintains a rotating state and the batter nozzle 131 rotates completely, the electric appliance automatic control unit controls the third motor to drive the fixed bracket 141 to rotate from the side of the flattening device to the opposite side of the spraying device 130 so as to drive the flattening shovel 142 to rotate from the side of the flattening device to the opposite side of the spraying device 130, thereby flattening the batter at the upper part of the griddle 120 to form a first-stage pancake to be folded, and enabling the thicknesses of a plurality of positions of the first-stage pancake to be folded to be approximately consistent in the vertical direction. Wherein the leveling blade 142 is positioned above the griddle 120. When the pancake to be folded is formed in the first stage, the leveling blade 142 rotates, and the automatic electric control unit controls the first motor to stop rotating, so that the rotation of the griddle 120 is stopped. Here, it should be noted that, the rotation of the leveling blade 142 means that the automatic electrical control unit controls the third motor to drive the fixing bracket 141 to rotate from the opposite side of the surface spraying device 130 to the side of the leveling mechanism 140, so as to drive the leveling blade 142 to rotate from the opposite side of the surface spraying device 130 to the side of the leveling mechanism 140, and finally reset the leveling blade 142 at the side of the leveling mechanism 140. The first stage involves the wafer to be folded being relatively hard on the side of the pan 120 and relatively soft on the side of the pan 120 away from the pan.

In one embodiment of the present invention, the opposite side of the console 110 provided with the spraying means 130 is provided with a reverse side assisting means 150 for assisting the turnover of the pancake to be folded in the first stage. Specifically, the back side auxiliary device 150 includes an auxiliary rod 151, and the auxiliary rod 151 is a telescopic long-strip structure. One end of the auxiliary rod 151, which is close to the flattening device mechanism 140, is fixed on a fourth rotating shaft, and the fourth rotating shaft extends downwards and is fixedly connected with an output shaft of a fourth motor. The fourth motor is used to drive the auxiliary lever 151 to rotate around the axial direction of the fourth rotation shaft from the side of the back side auxiliary device 150 toward the side of the stand mechanism 140. The fourth motor is electrically connected with the electrical appliance automatic control unit. Wherein the auxiliary rod 151 is positioned above the griddle 120. An auxiliary sliding table 152 with a long strip structure is provided on a side of the auxiliary rod 151 away from the console 110, and the auxiliary sliding table 152 extends toward the side and the opposite side of the spreader mechanism 140. A fifth motor is arranged at one end of the auxiliary sliding table 152 close to the flattening device mechanism 140, and a sixth motor is movably connected to the auxiliary sliding table 152. Wherein, the fifth motor and the sixth motor are electrically connected with the automatic control unit of the electric appliance. The fifth motor is used for driving the sixth motor to do linear reciprocating motion along the axial direction of the auxiliary sliding table 152, the output shaft of the sixth motor is fixed with a separating knife 153 with a strip plate structure, and the sixth motor is used for driving the separating knife 153 to rotate from the side of the reverse surface auxiliary device 150 to the side of the flattening device mechanism 140. When the axial direction of the separating knife 153 and the axial direction of the auxiliary sliding table 152 are perpendicular to each other, the lower portion of the separating knife 153 can be abutted against the upper portion of the griddle 120.

Specifically, when the rotation of the leveling blade 142 is completed, the electric appliance automatic control unit controls the sixth motor to start driving the separation blade 153 to rotate from the side of the reverse side auxiliary device 150 to the side of the leveling mechanism 140, and when the axial direction of the separation blade 153 is perpendicular to the axial direction of the auxiliary sliding table 152, the electric appliance automatic control unit controls the sixth motor to stop working, so that the axial direction of the separation blade 153 is perpendicular to the axial direction of the auxiliary sliding table 152. In the state of maintaining the mutual verticality, the automatic electrical control unit controls the fifth motor to drive the sixth motor to move along the axial direction of the auxiliary sliding table 152 from the opposite side of the flattening device 140 to the side of the flattening device 140, so as to drive the separating knife 153 to move from the opposite side of the flattening device 140 to the side of the flattening device 140. The lower part of the separating knife 153 can be abutted against the upper part of the griddle 120, so that one surface of the pancake to be folded, which is attached to the griddle 120 in the first stage, is separated from the upper part of the griddle 120. When the separation blade 153 moves to the side of the spreader mechanism 140, the electric appliance automatic control unit controls the fourth motor to drive the auxiliary lever 151 to extend in the axial direction of the auxiliary lever 151 and drive the auxiliary lever 151 to rotate from the side of the reverse side auxiliary device 150 toward the side of the spreader mechanism 140. When the included angle between the axial direction of the auxiliary rod 151 and the side of the reverse side auxiliary device 150 is 30-45 degrees, the automatic control unit of the electric appliance controls the fourth motor to stop working. At this time, the electric appliance automatic control unit controls the mechanical arm to move to the opposite side of the side where the spreader mechanism 140 is located. The robot arm then drops to the upper portion of the distal end of the griddle 120 opposite the spreader mechanism 140 and grasps the first stage of the pancake to be folded. The arm then rises to bring the first stage of the pancake to be folded up above the auxiliary lever 151 relative to the distal end of the flattening mechanism 140. The mechanical arm then performs a 180 degree turn to drive the first stage pancake to be folded 180 degrees over the distal end of the flattening mechanism 140. Then, the mechanical arm moves from the opposite side of the flattening device 140 to the side of the flattening device 140 to drive the distal end of the pancake to be folded in the first stage to move towards the side close to the flattening device 140 relative to the distal end of the flattening device 140. Finally, the arm is abutted against the side of the spreader mechanism 140, and the arm is lowered to the upper part of the end of the griddle 120 near the spreader mechanism 140, and the pancake to be folded in the first stage is released. At the same time, the electric appliance automatic control unit controls the fourth motor to drive the auxiliary lever 151 to rotate, and the overturning of the pancake to be folded in the first stage is completed. Here, when the auxiliary lever 151 rotates, the auxiliary lever 151 rotates from the axial direction of the auxiliary lever 151 at an angle of 30 degrees with the side of the opposite side auxiliary device 150 to complete the reset. When the pancake to be folded is turned over in the first stage, the electric appliance automatic control unit controls the fifth motor to drive the sixth motor to move from the side of the flattening machine mechanism 140 to the opposite side of the flattening machine mechanism 140. At the same time, the electric appliance automatic control unit controls the sixth motor to drive the separation blade 153 to rotate. Here, the rotation of the separation blade 153 means that the separation blade 153 is changed from a state in which the axial direction of the separation blade 153 and the axial direction of the auxiliary slide table 152 are perpendicular to each other to a state in which the axial direction of the separation blade 153 and the axial direction of the auxiliary slide table 152 are parallel to each other.
