Description
Technical Field
[0001] This utility model relates to the technical field of food processing, and in particular to a pleating and shaping device for xiaolongbao (soup dumplings). Background Technology
[0002] In large canteens, to improve production efficiency when producing xiaolongbao (soup dumplings), a pleating machine is needed to pleat the surface of the dumplings. Existing technology, a utility model patent with patent application number 202222399492.9, discloses a pleating machine, mainly composed of a pleating machine and a conveyor belt. When pleating the dumplings, the machine pleats the dumplings below the machine head, and then the conveyor belt transports the pleated dumplings to the outside for steaming or storage. However, this method has the following problems: During production, the freshly formed dumplings contain a certain amount of moisture. To prevent multiple dumplings from sticking together during subsequent freezing or steaming, workers need to sprinkle a layer of flour on the pleated surface to reduce sticking. However, relying on workers to manually sprinkle flour on the dumplings is extremely labor-intensive and inconvenient for large-scale production. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a small steamed bun pleating and forming device that can assist workers in sprinkling flour on the surface of the pleated buns, reducing labor intensity, and is easy to use and highly practical.
[0004] This utility model relates to a xiaolongbao (soup dumpling) pleating and forming device, comprising a ground surface, a belt conveyor, a conveyor belt, and a dumpling shaping machine. The belt conveyor is installed on the ground and has a conveyor belt. The dumpling shaping machine is also installed on the ground and has a machine head. It further includes a support frame, a feeding mechanism, and a powder spraying mechanism. The support frame is installed on the ground, and both the feeding and powder spraying mechanisms are mounted on the support frame. The feeding mechanism supplies rice flour to the powder spraying mechanism, which is located above the conveyor belt and has the function of spraying powder. During the production of xiaolongbao, the dumpling is pleated on the machine head of the dumpling shaping machine. The pleated dumpling is then conveyed to the conveyor belt, which transports it to the area below the powder spraying mechanism. The powder spraying mechanism then sprays powder onto the surface of the dumpling. Finally, the conveyor belt transports the powdered dumpling to an external collection mechanism for collection before steaming or freezing. This device assists workers in spraying flour onto the surface of pleated dumplings, reducing labor intensity, and is convenient and highly practical.
[0005] Preferably, the feeding mechanism includes a powder storage bin and a discharge pipe. The powder storage bin is fixedly installed on the upper part of the support. A cavity is provided inside the powder storage bin. A discharge pipe communicating with the cavity is provided at the lower part of the powder storage bin. A solenoid valve is provided on the discharge pipe, which is located above the powder sprinkling mechanism. The powder storage bin stores flour. When it is necessary to sprinkle flour on the surface of the buns, the solenoid valve on the discharge pipe is opened, allowing a portion of the flour in the powder storage bin to fall into the powder sprinkling mechanism through the discharge pipe, thus facilitating the sprinkling of flour on the surface of the buns.
[0006] Preferably, the powder-sprinkling mechanism includes a box body, a powder-sprinkling box, a vibrating motor, and two sets of flexible mechanisms. The box body is fixedly mounted on a support, and a cavity is provided inside the box body. An opening communicating with the cavity is provided at the lower end of the box body.

A storage chamber is provided inside the powder-sprinkling box, and multiple through holes communicating with the storage chamber are provided at the lower end of the powder-sprinkling box. A filter screen is provided at the lower end of the powder-sprinkling box. The vibrating motor is mounted on the powder-sprinkling box, and the lower end of the discharge pipe passes through the upper sidewall of the box body and is located above the powder-sprinkling box. When the shaped buns move to the bottom of the box body, flour is first conveyed into the powder-sprinkling box through the powder storage bucket and the discharge pipe. Then, the vibrating motor is turned on to make the powder-sprinkling box vibrate left and right, so that the flour in the powder-sprinkling box is discharged through the filter screen at the lower end of the powder-sprinkling box and falls onto the surface of the buns, which facilitates the sprinkling of flour onto the surface of the buns and reduces the sticking between the buns.
[0007] Preferably, the flexible mechanism includes a fixed column, a sliding column, and a spring.
