Description

Technical Field

[0001] This utility model relates to a food processing machine, and more specifically, to a semi-automatic shumai machine. Background Technology

[0002] Shaomai is a traditional stuffed food. With the development of food machinery, automated shaomai production equipment has emerged on the market. This equipment can automatically complete the filling, wrapping, and shaping processes, significantly increasing efficiency compared to traditional manual methods. However, my country's food culture is diverse, and shaomai alone has many different forms depending on its filling, requiring different levels of precision from the mechanized equipment. For example, glutinous rice shaomai has a firmer filling with less fluidity, making it easier to shape during wrapping and requiring less precision in the forming molds. Meat shaomai, on the other hand, has a semi-fluid filling, requiring higher precision in the forming molds to prevent leakage after wrapping. Furthermore, in some regions of my country, different thicknesses of dough are used to make shaomai, with specific requirements for the shape of the dough after wrapping. For instance, the bottom of the finished shaomai has a thicker dough to prevent breakage during steaming, while the top dough is thinner, allowing it to unfurl after wrapping, resulting in a more aesthetically pleasing appearance. Due to the aforementioned restrictions, this type of shumai cannot be made using the aforementioned standardized automated production equipment. Therefore, considering the special nature of its wrapper, it is necessary to conduct further research and improvement on the shumai production equipment, especially the structure of the forming mold. Utility Model Content

[0003] One of the purposes of this utility model is to address the above-mentioned shortcomings by providing a semi-automatic shumai machine, in order to solve the technical problems such as the inability of similar automatic shumai production equipment to complete the wrapping and shaping process due to the influence of unconventional thickness of the wrapping material.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a semi-automatic shumai machine, including a frame, a workstation turntable mounted on the frame, and multiple forming molds mounted on the turntable. Each forming mold includes a cylindrical receiving cavity, with a top core column at the lower part of the receiving cavity. The lower end of the top core column is mounted on a lifting frame, and the upper end of the top core column is placed in a cup body. A receiving tray is provided at the upper part of the receiving cavity, with an opening that communicates with the receiving cavity. The inner edge of the opening is annular and wavy. The receiving tray also has multiple strip-shaped protrusions, which are distributed in a radiating pattern around the opening.

[0006] As a preferred embodiment, a further technical solution is as follows: the workstation turntable is connected to the motor for power, and the frame around the workstation turntable has a skin receiving station, a filling station, a forming station and an ejection station. The filling station is equipped with a filling machine, the ejection station is equipped with a push rod, and the ejection station is also equipped with a conveyor belt corresponding to the push rod.

[0007] A further technical solution is that the workstation turntable is equipped with eight sets of forming molds, each set having two forming molds.

[0008] A further technical solution is that a leather material sensor is also installed on the frame near the injection machine, and the leather material sensor is used to connect to the main control module.

[0009] As a preferred embodiment, a further technical solution is as follows: the accommodating cavity is formed by multiple circumferentially distributed assemblies, the assemblies are movably mounted on the dial, the dial is movably mounted on the support, the support is mounted on the fixed plate, the dial is also poweredly connected to the connecting rod, the connecting rod is poweredly connected to the swing arm, and the swing arm is used to drive the dial to rotate through the connecting rod, so that the multiple assemblies can be radially opened and closed.

[0010] A further technical solution is: the lifting frame is placed below the fixed plate, and the top core column passes through the fixed plate and the guide channel and is placed in the lower part of the accommodating cavity.

[0011] A further technical solution is that the forming mold has two or three parts, and the dials are all connected to the same swing arm via connecting rods.

[0012] Compared with the prior art, one of the beneficial effects of this utility model is that by designing an annular wave-shaped structure and multiple radiating strip-shaped protrusions on the opening edge of the receiving tray of the forming mold, the annular wave-shaped structure and multiple radiating strip-shaped protrusions can help the thinner areas of the skin to spread out in a flower-like shape after the skin of the unconventional thickness is placed on the receiving tray, thus improving the aesthetics of the shumai after forming. In addition, the thicker area in the middle of the skin enters the receiving cavity and the cup body under the action of the filling tube, so that the bottom of the shumai is not easily damaged during forming and subsequent steaming. Therefore, it can be used in a semi-automatic shumai forming equipment where the skin is placed manually, to make shumai with unconventional thickness skin, and to meet different production needs.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] refer to Figure 1 and Figure 2 As shown, one embodiment of this utility model is a semi-automatic shumai machine. The structure of this semi-automatic shumai machine is similar to that of a similar automatic shumai machine, namely, it includes a frame 20, on which a station turntable 21 is installed. Multiple forming molds 30 are installed on the station turntable 21. In use, the station turntable 21 is poweredly connected to the output shaft of a motor through a central shaft. The motor can be a geared motor, a stepper motor, or a servo motor. The motor drives the station turntable to rotate 45 degrees each time. Thus, a skin-receiving station 22, a filling station 23, a forming station 24, and an ejection station 25 can be set around the station turntable 21. There are also transition stations between each of the aforementioned stations, for a total of eight stations. A filling machine 26 is installed at the filling station 23, a push rod 27 is installed at the ejection station 25, and finally a conveyor belt 28 corresponding to the push rod 27 is installed at the ejection station 25. As shown in the figure, the push rod 27 and the conveyor belt 28 are respectively placed on both sides of the ejection station 25. As mentioned above, the structure of the semi-automatic shumai machine in this embodiment is similar to that of similar automatic shumai machines. Therefore, the structures of the conveyor belt 28, push rod 27, and filling machine 26 can be used interchangeably with those of similar shumai machines. Therefore, in this embodiment, the structure and principle of the conveyor belt 28, push rod 27, and filling machine 26 will not be described in detail. Those skilled in the art can refer to the structure of the disclosed similar shumai machines to implement this embodiment.

[0022] More importantly, refer to Figure 3 As shown, the main improvement of this utility model is the forming mold that assists in the blooming of shumai wrappers. In this embodiment, the forming mold 30 includes a cylindrical receiving cavity 1. The lower part of the receiving cavity 1 is provided with a top core column 2. The lower end of the top core column 2 is mounted on a lifting frame 3. The lifting frame 3 can be powered by a power facility on the frame 20. The power facility drives the lifting frame 3 to rise and fall. Furthermore, the upper end of the top core column 2 is placed in the cup body 4. Through the aforementioned structure, under the action of the lifting frame 3, the top core column 2 can be moved up and down in the cup body 4. When the top core column 2 moves upward, the upper end of the top core column 2 is placed in the lower part of the aforementioned receiving cavity 1. Simultaneously, the upper part of the aforementioned receiving cavity 1 is also provided with a receiving tray 5, which can... Figure 4 The design shown is circular, with an opening 51 in the center of the receiving tray 5. This opening 51 corresponds to the filling pipe of the filling machine. The filling pipe inserts the dough into the receiving cavity 1 through this opening 51 to complete the filling. Therefore, the opening 51 needs to be connected to the receiving cavity 1, and the inner edge of the opening 51 needs to be annular and wavy. To complement this, multiple strip-shaped protrusions 52 need to be designed on the receiving tray 5. These strip-shaped protrusions 52 are distributed in a radiating pattern around the opening 51. See reference [reference needed] for details. Figure 6 As shown.

[0023] In this embodiment, by designing an annular wave-shaped structure and multiple radiating strip-shaped protrusions 52 on the opening edge of the receiving tray 5, after the non-standard thickness of the dough is placed on the receiving tray 5, the strip-shaped protrusions 52 can pre-form wave-shaped pleats around the dough. The inner edge of the annular wave-shaped opening can increase the circumference of the opening edge, which is beneficial to increase the number of pleats blooming after the shumai is wrapped. That is, the annular wave-shaped structure and the multiple radiating strip-shaped protrusions 52 can help the thinner areas of the dough to spread out in a blooming shape, improving the aesthetics of the shumai after it is formed. Furthermore, the thicker area in the middle of the dough enters the receiving cavity 1 and the cup body 4 under the action of the filling tube, making it less likely for the bottom of the shumai to break during the forming and subsequent steaming. Thus, the semi-automatic shumai machine can be used to make shumai with non-standard thickness dough, meeting different production needs.

[0024] Furthermore, in terms of the structural design of the forming mold, to facilitate forming and encapsulation, the accommodating cavity 1 can be designed as being formed by multiple circumferentially distributed assembly modules. These assembly modules are movably mounted on the dial 6, and then the dial 6 is movably mounted on the support 7. The support 7 is mounted on the fixed plate 8. The dial 6 is also poweredly connected to the connecting rod 9, and the connecting rod 9 is poweredly connected to the swing arm 10. The swing arm 10 is used to drive the dial 6 to rotate through the connecting rod 9, so that the multiple assembly modules can open and close radially. In use, the aforementioned swing arm 10 is poweredly connected to the drive device on the frame 20. Based on the above idea, the forming mold can be designed in pairs, with the dial 6 being poweredly connected to the same swing arm 10 through the connecting rod 9. On the other hand, to facilitate linkage, the lifting frame 3 can be placed below the fixed plate 8, and the top core column 2 passes through the fixed plate 8 and the guide channel and is placed in the lower part of the accommodating cavity 1, specifically as follows. Figure 4 As shown.

[0025] Meanwhile, to prevent filling from entering the receiving cavity 1 due to the absence of dough on the receiving tray 5 of the forming mold 30 when the filling machine 26 is filling the forming mold 30, thus affecting the normal use of the forming mold, a dough sensor can be installed on the frame near the filling machine 26. This dough sensor is used to connect to the main control module. The dough sensor can be a common position sensor. That is, when the sensor detects that there is no dough on the receiving tray 5 of the current forming mold 30, the filling machine will no longer fill the forming mold 30 currently placed at the filling station 23, thus avoiding accidental operation that causes the filling to enter the receiving cavity 1.

[0026] refer to Figures 1 to 5As shown, in actual use, in one preferred embodiment of the present invention, eight sets of forming molds 30 are installed on the workstation turntable 21, corresponding to the skin-receiving workstation 22, the filling workstation 23, the forming workstation 24, and the ejection workstation 25 respectively. The workstation turntable 21 drives multiple forming molds to enter the aforementioned skin-receiving workstation 22, the filling workstation 23, the forming workstation 24, and the ejection workstation 25 in sequence. The workstation turntable 21 drives the aforementioned eight sets of forming molds 30 to rotate at an angle of 45 degrees each time. Each time it rotates, one set of forming molds 30 enters the aforementioned corresponding workstation. At the dough receiving station 22, a pre-made shumai wrapper is manually placed on the receiving tray 5. This wrapper has an unconventional thickness, being thicker in the middle and thinner at the edges. The forming mold 30, carrying the wrapper, enters the filling station 23. The filling pipe of the filling machine 26 pushes the center of the wrapper into the receiving cavity 1 and simultaneously completes the filling. During this process, the wavy inner edge of the opening of the receiving tray 5 and the radiating strip-shaped protrusions cause the wrapper to quickly open and spread out after entering the receiving cavity 1, forming the target shape. At the same time, the... After entering the forming station 24, the top core column 2 is placed at the bottom of the receiving cavity 1 and slightly raised by the lifting frame to flatten the bottom of the shumai dough. Then, the drive device moves the swing arm 10, which in turn drives the dial 6 to rotate via the connecting rod 9. This causes multiple assembly modules to radially close together in the receiving cavity 1, creating radial pressure on the shumai dough and completing the shaping. The forming mold then continues to enter the ejection station 25, where the push rod 27 ejects the finished shumai from the forming mold 30 onto the conveyor belt 28. During the operation of the semi-automatic shumai machine, the aforementioned process is continuously repeated.
