[0034] Reference Figures 1 to 3 This utility model proposes a cake-making machine with a braking circuit, comprising:

[0035] Casing 10;

[0036] The main body of the device is mounted on the housing 10; and

[0037] The braking circuit includes a power module, a resistor 31, a drive motor 32, and a changeover switch 33. The drive motor 32 is mounted on the housing 10 and is connected to the main body of the device. The changeover switch 33 is connected to one end of the power module, one end of the resistor 31, and one end of the drive motor 32. The other end of the drive motor 32 is connected to the other end of the resistor 31 and the other end of the power module. The power module supplies power to the drive motor 32 when the changeover switch 33 is in a first closed state and stops supplying power to the drive motor 32 when the changeover switch 33 is in a second closed state. The drive motor 32 operates normally when the changeover switch 33 is in the first closed state and transfers the potential energy generated by the drive motor 32 to the resistor 31 when the changeover switch 33 is in the second closed state.

[0038] The technical solution of this utility model includes a cake maker with a braking circuit, comprising a housing 10, a main body, and a braking circuit. The main body is mounted on the housing 10. The braking circuit includes a power module, a resistor 31, a drive motor 32, and a changeover switch 33. The drive motor 32 is mounted on the housing 10 and is connected to the main body for transmission. The changeover switch 33 is connected to one end of the power module, one end of the resistor 31, and one end of the drive motor 32. The other end of the drive motor 32 is connected to the other end of the resistor 31 and the other end of the power module. The power module supplies power to the drive motor 32 when the changeover switch 33 is in the first closed state and stops supplying power to the drive motor 32 when the changeover switch 33 is in the second closed state. The drive motor 32 is used to operate normally when the changeover switch 33 is in the first closed state. During normal operation, when the selector switch 33 is in the second closed state, the potential energy generated by the drive motor 32 is transferred to the resistor 31; that is, when the selector switch 33 is in the first closed state, the power module supplies power to the drive motor 32, and the resistor 31 is disconnected from the drive motor 32, so that the drive motor 32 drives the main body of the equipment to operate normally; when the main body of the equipment needs to be stopped, the selector switch 33 switches from the first closed state to the second closed state. At this time, the power module is disconnected from the drive motor 32, and the drive motor 32 is connected in series with the resistor 31. Although the drive motor 32 and the power module are disconnected, the drive motor 32 will still run for a period of time under the action of inertia. Therefore, most of the potential energy generated by the drive motor 32 under the action of inertia is consumed through the resistor 31, thereby reducing the braking distance and improving the accuracy.

[0039] In one embodiment of this utility model, the main body of the equipment includes a material bin 21, a dough mixing module 22, a baking module 23, a transfer module 24, and a cake pushing module 25, all installed on the housing 10. Each of the dough mixing module 22, the baking module 23, the transfer module 24, and the cake pushing module 25 is respectively equipped with a braking circuit. By providing a braking circuit to each of the modules (material bin 21, dough mixing module 22, baking module 23, transfer module 24, and cake pushing module 25) equipped with a drive motor 32, the braking distance during movement of each module is reduced, thereby improving the accuracy of movement. Of course, if each module has multiple drive motors 32, each motor will correspond to a braking circuit.

[0040] The material bin 21 is used to hold flour, water, oil or other seasonings. The material bin 21 is connected to the dough mixing module 22. The material in the material bin 21 flows into the dough mixing module 22, and then the dough mixing module 22 mixes the material into dough. Further, the transfer module 24 transfers the dough on the mixing module to the lower baking pan 232. The transfer module 24 can be a robotic arm or a carrier plate to hold the dough. Then, the carrier plate is driven to move by a drive structure, so that the dough in the dough mixing module 22 is transferred to the lower baking pan 232.

[0041] Reference Figures 4 to 7 In one embodiment of this utility model, the baking module 23 includes an upper baking pan 231, a lower baking pan 232, and a transmission assembly. Both the upper baking pan 231 and the lower baking pan 232 are mounted on the housing 10, with the lower baking pan 232 located below the upper baking pan 231. The corresponding drive motor 32 is connected to the upper baking pan 231 via the transmission assembly to drive the upper baking pan 231 to rise and fall. When the dough is transferred from the mixing chamber to the lower baking pan 232 via the transfer module 24, the drive motor 32 lowers the upper baking pan 231 via the transmission assembly, thereby pressing the dough on the lower baking pan 232 together. Simultaneously, both sides of the dough are baked. After baking, the drive motor 32 raises the upper baking pan 231 via the transmission assembly, and then the pancake pusher module 25 pushes the baked pancake off the lower baking pan 232.

[0042] Specifically, the transmission assembly includes a first transmission wheel 233, a second transmission wheel 234, and a transmission rod 235. The first transmission wheel 233 is connected to the output shaft of the corresponding drive motor 32. The second transmission wheel 234 is rotatably mounted on the housing 10 and meshes with the first transmission wheel 233. Both ends of the transmission rod 235 are rotatably connected to the second transmission wheel 234 and the upper baking pan 231, respectively. The drive motor 32 drives the second transmission wheel 234 to rotate through the first transmission wheel 233, so that the transmission rod 235 drives the upper baking pan 231 to rise and fall.

[0043] Furthermore, the second transmission wheel 234 is arranged in a fan shape, and includes a gear portion 2341 and a stop groove 2342. When the first transmission wheel 233 meshes with the gear portion 2341, the drive motor 32 drives the upper baking pan 231 to rise and fall; when the first transmission wheel 233 is located in the stop groove 2342, the upper baking pan 231 is stationary. The stop groove 2342 serves as a backup component to prevent the upper baking pan 231 from rising and falling excessively, thus acting as a safety feature.

[0044] The upper baking pan 231 has two stop grooves 2342, which are located at both ends of the gear section 2341. If the upper baking pan 231 continues to rise after reaching the predetermined highest point, or continues to descend after reaching the predetermined lowest point, the drive wheel rotates into the corresponding stop groove 2342, allowing the drive wheel to idle. In this case, the drive wheel will not drive the transmission wheel to rotate, and therefore will not cause the upper baking pan 231 to rise or fall, thus improving the stability of the upper baking pan 231. It should be noted that the predetermined highest point, i.e., the upper baking pan 231 and / or guide rod, will not interfere with other parts of the pie maker during its ascent; the predetermined lowest point is the position where the upper baking pan 231 moves to press the dough on the lower baking pan 232 into shape and bake it.

[0045] Furthermore, the outer peripheral surface of the upper baking pan 231 is provided with a guide protrusion 2311, and the housing 10 is provided with a guide groove 11. The upper baking pan 231 is slidably connected to the housing 10 through the cooperation of the guide protrusion 2311 and the guide groove 11. By setting the guide protrusion 2311 and the guide groove 11, the upper baking pan 231 can slide along a predetermined track, thereby further increasing the stability of the upper baking pan 231's operation based on the setting of the guide rod.

[0046] Reference Figure 8 and Figure 9 In one embodiment of this utility model, the pancake pushing module 25 includes a third transmission wheel 251, a transmission chain 252, and a push rod 253. The third transmission wheel 251 is connected to the corresponding drive motor 32. The transmission chain 252 includes multiple interconnected drag chain links, each with a transmission hole 2521. The third transmission wheel 251 engages with the transmission chain 252 through the transmission hole 2521. The push rod 253 is connected to one end of the drag chain. The drive motor 32 pushes the push rod 253 to move via the third transmission wheel 251 and the transmission chain 252, thereby pushing the baked pancakes off the baking module 23. The drive motor 32 of the pancake pushing module 25 drives the third transmission wheel 251 to rotate, which in turn causes the transmission chain 252 to extend or retract, thereby causing the push rod 253 to extend or retract. When the push rod 253 extends, it pushes the pancakes off the lower baking tray 232. Compared to the existing technology where the transmission rod 235 drives the push rod 253, the transmission chain 252 can bend after the contraction process, while the transmission rod 235 remains upright. Therefore, the transmission method of the transmission chain 252 occupies less space. However, if the transmission rod 235 adopts a telescopic rod or other similar design, it may result in higher cost and more complex structure.

[0047] Furthermore, there are two transmission chains 252, one end of which is rotatably connected to the push rod 253. The corresponding drive motor 32 engages with the transmission hole 2521 on one of the transmission chains 252. The transmission chains 252 are bent to one side, and the two transmission chains 252 are arranged symmetrically side by side to prevent the push rod 253 from deviating when the drive motor 32 drives the push rod 253 to move. Since both transmission chains 252 are bent to one side and are symmetrically distributed, when the third transmission wheel 251 drives one transmission chain 252 to extend, the other transmission chain 252 also extends through the push rod 253. Because the two transmission chains 252 are arranged side by side, they restrain each other, so that the extended parts of the two transmission chains 252 remain upright, while the parts not driven by the third transmission wheel 251 remain freely bent.

[0048] Furthermore, the housing 10 is also provided with two receiving slots 12, and the two transmission chains 252 are respectively housed in the two receiving slots 12, so that the transmission chains 252 retract according to a predetermined trajectory, preventing the transmission chains 252 from getting tangled or swinging too freely and interfering with other parts of the cake maker.

[0049] Specifically, the cable chain includes multiple cable chain sections rotatably connected, each of which is provided with a first limiting part and a second limiting part. The transmission chain 252 bends on one side only through the first limiting part and the second limiting part. Further, the first limiting part is a first limiting protrusion 2522, and the second limiting part is a second limiting protrusion 2523. By providing the first limiting protrusion 2522 and the second limiting protrusion 2523, the transmission chain 252 can only bend on one side. Of course, in other embodiments, the first limiting part and the second limiting part can also be a limiting rod, a limiting groove, etc.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
