specifically, when the turnover clamp 212 which is originally at the first position and the full-load die plate are turned over to the second position, the first sensor 42 in the detection mechanism 4 detects whether the die plate is respectively adsorbed in the turnover clamp 212 at the second position, if not, the alarm mechanism 5 gives an alarm to the outside, if so, the second sensor 43 detects whether the toast in the die plate is demoulded (i.e. falls off from the die plate), if not, the alarm mechanism 5 gives an alarm to the outside, if so, the third sensor 44 detects whether the toast falls on the cake turning conveyor belt 31, if so, the demould quantity is further counted, whether the full-load die plate is completely demoulded is further determined, if not, the fourth sensor 45 detects whether the falling position of the toast deviates from the cake turning conveyor belt 31, and if so, the alarm mechanism 5 gives an alarm to the outside. The all-round control of drawing of patterns to the template through a plurality of sensors in this embodiment to reduce the cost of labor, improve whole drawing of patterns efficiency.

S4: judging whether the mold stripping of the mold plate in the second position is finished, if not, giving a warning to the outside, and if so, executing S5;

specifically, when the demolding condition detected by the detection mechanism 4 satisfies the following conditions at the same time, it can be determined that demolding is completed:

the mould disc is adsorbed in the turning clamping position 212 at the second position;

sixthly, completely dropping the toast from the die plate;

the toast falls into the cake turning conveyer belt 31;

eighthly, no toast deviates from the cake turning conveyer belt 31;

if the above conditions are different, a warning is sent to the outside.

S5: the turnover drive 23 drives the turnover roller 21 to turn along the motion track defined by the guide assembly 22, so as to move the turnover detent 212 loaded with the unloaded module to the first position.

Specifically, when the fully loaded mold plate is turned to the second position, the lifting cylinder drives the cake-turning conveyer belt 31 to move towards the second position, so that the cake-turning conveyer belt 31 is close to the mold plate in the second position, the phenomenon that toast is broken due to overlarge falling distance of toast is avoided, the probability that toast falls out of the cake-turning conveyer belt 31 is reduced, the cake-turning conveyer belt 31 conveys the toast to the conveying tail end of the toast, the height difference between the conveying tail end of the cake-turning conveyer belt 31 and the discharging conveyer belt 32 is utilized, so that the toast falls into the discharging conveyer belt 32 from the cake-turning conveyer belt 31 and turns over again, the front side of the toast faces upwards for subsequent packaging, after demolding is completed, the turnover motor 231 drives the turnover chain wheel 234 to drive the turnover roller 21 to rotate 180 degrees in a short time (1 second) through the transmission unit 235, so that the turnover clamping position 212 originally located at the first position and the fully loaded mold plate are turned to the second position (in the initial state, the opening direction of the die disc is upward, after the die disc is turned, the opening direction of the die disc is downward, so that toast in the die disc can fall out), the turning clamping position 212 at the second position and the empty die disc are turned to the first position (under the initial state, the opening direction of the die disc is downward, after the die disc is turned, the opening direction of the die disc is upward, so that the die disc entering a subsequent cleaning link does not need to be turned over again), under the pushing of the conveying push plate 13, the full-load die disc enters the turning clamping position 212 at the first position, and the empty die disc originally placed on the turning clamping position 212 is pushed to the disc-discharging conveying belt 33, so that the empty die disc is conveyed to be cleaned by the disc-discharging conveying belt 33.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes should fall within the scope of the claims of the present invention.
