Both ends of the flour box 11 are fixedly connected to the bottom surface of the second connecting rod 9, and a flour inlet is opened at the bottom of the flour box 11.

[0020] When the power to conveyor belt 1 is turned on, dough balls fall onto one end of conveyor belt 1 and are conveyed one by one by conveyor belt 1. When the power to servo motor 3 is turned on, servo motor 3 drives the eccentric shaft of eccentric wheel 7 to rotate. Eccentric wheel 7 rotates in insertion groove 16, and insertion groove 16 is adapted to eccentric wheel 7. Eccentric wheel 7 drives transmission frame 6 to move in a circular trajectory, and first connecting rod 8 moves accordingly. First connecting rod 8 slides in the cavity of second connecting rod 9. Second connecting rod 9 slides left and right in the middle of support column 10. The left and right movement of second connecting rod 9 drives flour box 11 to move left and right. The flour inside the flour box 11 is sprinkled onto the passing dough through the flour inlet to prevent the dough from sticking. The first connecting rod 8 drives the rubbing board 12 to move in a circular trajectory. The bottom surface of the rubbing board 12 contacts the top of the dough. The dough is conveyed and kneaded while being rotated, and the dough is shaped into a round shape for easy shaping later. The dough is conveyed while being kneaded. A PLC controller is set on the other side of the conveyor belt 1. The conveyor belt 1 and the servo motor 3 are both electrically connected to the PLC controller. The speed of the rubbing board and the speed of the conveyor belt are set to ensure that each piece of dough is kneaded a few times before being sent out.

[0021] A dough conveying mechanism for a dessert bun forming machine, such as Figure 1 , Figure 3 and Figure 5 As shown, the conveyor belt 1 is set above the ground. The rounding structure also includes a bolt 13, a first extension rod 14, and a second extension rod 15. One end of the first extension rod 14 is fixedly connected to one end of the first connecting rod 8. One end of the second extension rod 15 is set in the cavity of the first extension rod 14 and is slidably connected to the first extension rod 14. A bolt 13 is set on the wall of the first extension rod 14. Several threaded holes are opened on the wall of the second extension rod 15. The bolt 13 is threadedly connected to the threaded holes. The other end of the second extension rod 15 is fixedly connected to the top surface of the washboard 12. A slot 5 is opened on each side of the top surface of the conveyor belt 1. A protective cover 2 is set in the slot 5. The two ends of the protective cover 2 are engaged with the slot 5. A partition 18 is opened on the top surface of the protective cover 2. A side opening 19 is opened on each side of the protective cover 2. The two ends of the second connecting rod 9 are set in one side opening 19 and are slidably connected to the side opening 19.

[0022] Depending on the type of dessert bun, the dough comes in various sizes. For the same batch of dough, rotate bolt 13 to adjust the length of extension rod 15, and screw bolt 13 into the corresponding threaded hole so that the kneading board 12 always contacts the top of the dough. This is suitable for dough of various sizes. During operation, insert both ends of the protective cover 2 into the slot 5 and fit the servo motor 3 to prevent dust contamination during the dough conveying process. The kneaded dough is then conveyed from the other end of the conveyor belt 1 to the dessert bun forming machine.

[0023] The working principle of this utility model is as follows: When the power to the conveyor belt 1 is turned on, the dough falls onto one end of the conveyor belt 1, and the dough is conveyed one by one by the conveyor belt 1. When the power to the servo motor 3 is turned on, the servo motor 3 drives the eccentric shaft of the eccentric wheel 7 to rotate. The eccentric wheel 7 rotates in the insertion groove 16, and the insertion groove 16 is adapted to the eccentric wheel 7. The eccentric wheel 7 drives the transmission frame 6 to move in a circular trajectory, and the first connecting rod 8 moves accordingly. The first connecting rod 8 slides in the cavity of the second connecting rod 9, and the second connecting rod 9 slides left and right in the middle of the support column 10. The left and right movement of the second connecting rod 9 drives the flour box 11 to move left and right. The flour inside the flour box 11 is sprinkled onto the passing dough through the powder outlet to prevent the dough from sticking. The connecting rod 8 drives the rubbing plate 12 to move in a circular trajectory. The bottom surface of the rubbing plate 12 contacts the top of the dough. The dough is conveyed and kneaded while rotating, and the dough is shaped into a round shape for easy subsequent shaping. The dough is conveyed while being kneaded. Depending on the type of dessert bun, the dough balls are of different sizes. According to the same batch of dough balls, the bolt 13 is rotated to adjust the length of the extension rod 15. The bolt 13 is screwed into the corresponding threaded hole so that the rubbing plate 12 always contacts the top of the dough ball. It is suitable for dough balls of various sizes. During operation, the two ends of the protective cover 2 are inserted into the slots 5 and the servo motor 3 is fitted in to prevent the dough from being contaminated by dust during the conveying process. The kneaded dough is conveyed from the other end of the conveyor belt 1 to the dessert bun forming machine.
