Description

Technical Field

[0001] This application belongs to the field of food processing technology, and in particular relates to a semi-automatic dumpling machine that can meet the needs of miniaturized production. Background Technology

[0002] Existing industrial automated quick-freezing food production equipment has a very complex structural design for each workstation in order to meet the functional requirements of each station. For industrial production, large-scale equipment can meet the production needs. However, in certain scenarios (such as canteens and restaurants), when a smaller food forming equipment is needed that can still basically meet the production needs, existing technology lacks the corresponding equipment.

[0003] In the prior art, many technical improvements have been made to miniaturize equipment. For example, Chinese Utility Model Patent Application No. CN201620374366.X, filed on April 28, 2016, entitled "A Compact Filled Food Forming Machine with Rotary Dough-Connecting Mechanism," describes its technical solution as follows: This utility model belongs to the field of food processing technology, and particularly relates to a compact filled food forming machine with rotary dough-connecting mechanism. It includes a frame and a workstation indexing plate located on the frame. Around the workstation indexing plate, a dough-making device, a filling device, a pressing device, and a discharging device are respectively arranged. The dough-making device is the dough-making station, the filling device is the filling station, the pressing device is the pressing station, and the discharging device is the discharging station. The frame is also equipped with a split-type forming mold, which includes an independent rotary dough-connecting plate and a mold cup. The rotary dough-connecting plate has multiple central holes for forming. The rotary dough-connecting plate is a disc, and the central holes are evenly distributed along the circumference of the rotary dough-connecting plate. The aforementioned patents, in order to give miniaturized equipment relatively complete functions, basically imitate the structural distribution of large industrial equipment, only reducing its size. However, this still makes the structure of the miniaturized equipment too complex, without adjusting the overall processing steps to adapt to the miniaturized structure. Summary of the Invention

[0004] To overcome the aforementioned problems with existing technologies, a semi-automatic dumpling machine is proposed that can meet the needs of food processing and achieve equipment miniaturization through improvements to the food forming and clamping structure.

[0005] To achieve the above-mentioned technical effects, the technical solution of this application is as follows:

[0006] A semi-automatic dumpling machine includes a frame, with a filling device and a forming device installed at both ends of the frame, the filling device and the forming device being arranged adjacent to each other;

[0007] The filling device is used to inject filling into the dough located on the forming device;

[0008] The forming device is equipped with a liftable mold cup and multiple forming molds. The multiple forming molds are mounted on an indexing plate and rotate with the indexing plate. At least a dough receiving station, a filling forming station, and a material unloading station are set around the indexing plate. The mold cup is located at the filling forming station. After the pressing forming block of the forming mold fills and shapes the dumpling at the filling forming station, the pressing forming block remains in a pressed state and moves to the material unloading station. The pressing forming block separates, allowing the dumpling to be unloaded downwards.

[0009] Furthermore, a synchronous pulley is installed on the frame, a lifting cam is coaxially connected to the synchronous pulley, the lifting cam is connected to a lifting swing arm, the lifting swing arm is connected to a lifting slider, a mold cup bracket is connected to the lifting slider, and the mold cup bracket is connected to the mold cup.

[0010] Furthermore, the forming mold includes a receiving plate with a forming hole in the middle. Below the forming hole is a pressing forming block for forming the dough and filling and for clamping the formed food. The pressing forming block is connected to a pressing transmission mechanism, which is connected to a power source. The power source drives the pressing transmission mechanism to move, and the pressing transmission mechanism drives the pressing forming block to open and close.

[0011] Furthermore, the pressing block includes a convex block and a concave block, the shapes of which are matched. After the convex block and the concave block are pressed together, the food sealing part is pressed and shaped, and the convex block and the concave block simultaneously contact the end of the food.

[0012] Furthermore, the pressure transmission mechanism includes two sets of upper and lower racks symmetrically distributed on both sides below the receiving plate. A reversing gear meshes between the set of upper and lower racks on the same side. The two upper racks are connected by an inner bracket, and the two lower racks are connected by an outer bracket. A concave block and an inner cam roller are installed on the inner bracket, and a convex block and an outer cam roller are installed on the outer bracket.

[0013] Furthermore, a reset spring is connected between the outer support and the inner support.

[0014] Furthermore, the power source includes a motor, the main shaft of which is connected to an opening and closing cam, one end of which is connected to a cam swing arm, and the other end of which is connected to an opening and closing push rod.

[0015] Furthermore, a push plate is provided at the end of the opening / closing push rod.

[0016] Furthermore, four workstations are evenly arranged around the indexing plate, namely, the skin receiving workstation, the filling and forming workstation, the material unloading workstation, and the standby workstation.

[0017] The advantages of this application are:

[0018] 1. This application simplifies the structure of the forming mold. All forming molds no longer have separate mold cups, but share the same mold cup. By combining filling and forming in one station, and then using the forming pressing block to unload the formed dumplings, the machine is miniaturized under the encapsulation forming scheme, eliminating the need to design separate pressing and forming stations and mechanisms.

[0019] 2. Since the filling and shaping are combined in one station, the handover time between the two actions is very short, and the intermediate steps are reduced, which is more advantageous when dealing with dough with high water content and low toughness.

[0020] 3. The integrated design of the compression molding block and the molding die enables the molding die to have product handling function, eliminating the need for a separate demolding or unloading mechanism and simplifying the equipment.

[0021] 4. Unlike existing single-station forming solutions, the multi-station design allows operators more spare time to place the dough without having to precisely follow the machine's rhythm, thus reducing labor intensity.

[0022] 5. Intermittent indexing workstations facilitate integration with upstream and downstream automation needs, such as automatic crust loading and automatic tray arrangement in the catering industry.

[0023] 6. The pre-reserved workstations in the design allow for easy expansion of the forming, trimming, and cutting functions, reducing the requirements for the precision of the dough's appearance and placement, and broadening the product's applicability. For example, common round dough sheets can also be used on this equipment; after food forming, excess dough can be cut off to obtain a standard finished product. Attached Figure Description

[0041] Example 1

[0042] like Figure 1 and Figure 2 As shown, a semi-automatic dumpling machine includes a frame 1. Both ends of the frame 1 are equipped with a filling device 2 and a forming device 3, which are arranged adjacent to each other. The filling device 2 is used to inject filling into the dough located on the forming device 3.

[0043] The forming device 3 is equipped with a liftable mold cup 4 and multiple forming molds 5. The multiple forming molds 5 are mounted on the indexing plate 6 and rotate with the indexing plate 6. At least a dough receiving station 7, a filling forming station 8, and a material unloading station 9 are provided around the indexing plate 6. The mold cup 4 is located at the filling forming station 8. After the pressing forming block 10 of the forming mold 5 fills and shapes the dumpling at the filling forming station 8, the pressing forming block 10 remains in a pressed state and moves to the material unloading station 9. The pressing forming block 10 separates, allowing the dumpling to be unloaded downwards.

[0044] Compared to traditional molding dies 5, the molding die 5 of this application eliminates the mold cup 4 structure, and multiple molding dies 5 share a single mold cup 4. The mold cup 4, through its own lifting action, can achieve technical effects such as lifting food, shaping, and avoiding the molding dies 5. The filling and shaping station 8 is a composite station, where food filling and shaping are simultaneously realized. A conveyor belt or a rotary table can be installed below the unloading station 9, depending on the needs of the application scenario. Alternatively, a conveyor belt, indexing plate 6, and other buffer devices may not be configured.

[0045] like Figure 5 and Figure 6 As shown, a synchronous pulley 11 is mounted on the frame 1. A lifting cam 12 is coaxially connected to the synchronous pulley 11. The lifting cam 12 is connected to a lifting swing arm 13. A lifting slider 14 is connected to the lifting swing arm 13. A mold cup bracket 15 is connected to the lifting slider 14 and is connected to the mold cup 4. The motor, powered by other equipment, drives the synchronous pulley 11 to rotate counterclockwise, causing the lifting cam 12, coaxially mounted with the synchronous pulley, to rotate accordingly. The rotation of the lifting cam 12 causes the lifting swing arm 13 to swing up and down. The swinging of the lifting swing arm 13 drives the lifting slider 14 to move. The mold cup 4 and the mold cup bracket 15 are fixed on the lifting slider 14 and move together with it. The lifting cam 12 rises or falls according to a preset timing rhythm, cooperating with the molding die 5 to form the product.

[0046] This application simplifies the structure of the forming mold 5. All forming molds 5 no longer have separate mold cups 4, but share the same mold cup 4. By combining filling and forming in one station, and then using the forming pressing block to remove the formed dumplings, the miniaturization of the machine under the encapsulation forming scheme is achieved, eliminating the need to design separate pressing and forming stations and mechanisms.

[0047] Example 2

[0048] like Figure 1 and Figure 2 As shown, a semi-automatic dumpling machine includes a frame 1. Both ends of the frame 1 are equipped with a filling device 2 and a forming device 3, which are arranged adjacent to each other. The filling device 2 is used to inject filling into the dough located on the forming device 3.

[0049] The forming device 3 is equipped with a liftable mold cup 4 and multiple forming molds 5. The multiple forming molds 5 are mounted on the indexing plate 6 and rotate with the indexing plate 6. At least a dough receiving station 7, a filling forming station 8, and a material unloading station 9 are provided around the indexing plate 6. The mold cup 4 is located at the filling forming station 8. After the pressing forming block 10 of the forming mold 5 fills and shapes the dumpling at the filling forming station 8, the pressing forming block 10 remains in a pressed state and moves to the material unloading station 9. The pressing forming block 10 separates, allowing the dumpling to be unloaded downwards.

[0050] Compared to traditional molding dies 5, the molding die 5 of this application eliminates the mold cup 4 structure, and multiple molding dies 5 share a single mold cup 4. The mold cup 4, through its own lifting action, can achieve technical effects such as lifting food, shaping, and avoiding the molding dies 5. The filling and shaping station 8 is a composite station, where food filling and shaping are simultaneously realized. A conveyor belt or a rotary table can be installed below the unloading station 9, depending on the needs of the application scenario. Alternatively, a conveyor belt, indexing plate 6, and other buffer devices may not be configured.

[0051] like Figure 5 and Figure 6 As shown, a synchronous pulley 11 is mounted on the frame 1. A lifting cam 12 is coaxially connected to the synchronous pulley 11. The lifting cam 12 is connected to a lifting swing arm 13. A lifting slider 14 is connected to the lifting swing arm 13. A mold cup bracket 15 is connected to the lifting slider 14 and is connected to the mold cup 4. The motor, powered by other equipment, drives the synchronous pulley 11 to rotate counterclockwise, causing the lifting cam 12, coaxially mounted with the synchronous pulley, to rotate accordingly. The rotation of the lifting cam 12 causes the lifting swing arm 13 to swing up and down. The swinging of the lifting swing arm 13 drives the lifting slider 14 to move. The mold cup 4 and the mold cup bracket 15 are fixed on the lifting slider 14 and move together with it. The lifting cam 12 rises or falls according to a preset timing rhythm, cooperating with the molding die 5 to form the product.

[0052] like Figures 7-10 As shown, the forming mold 5 includes a receiving plate 16, with a forming hole 17 in the middle of the receiving plate 16. Below the forming hole 17, there is a pressing forming block 10 for forming the dough and filling and for clamping the formed food. The pressing forming block 10 is connected to a pressing transmission mechanism, which is connected to a power source. The power source drives the pressing transmission mechanism to move, and the pressing transmission mechanism drives the pressing forming block 10 to open and close.

[0053] The compression molding block 10 includes a convex block 19 and a concave block 20. The convex block 19 and the concave block 20 are shaped to match each other. After the convex block 19 and the concave block 20 are pressed together, the food sealing part is compressed and shaped. The convex block 19 and the concave block 20 are in contact with the end of the food at the same time.

[0054] The pressure transmission mechanism includes two sets of upper racks 21 and lower racks 22 symmetrically distributed on both sides below the receiving plate 16. A reversing gear 23 meshes between the set of upper racks 21 and lower racks 22 on the same side. The two upper racks 21 are connected by an inner bracket 24, and the two lower racks 22 are connected by an outer bracket 25. A concave block 20 and an inner cam roller 26 are installed on the inner bracket 24, and a convex block 19 and an outer cam roller 27 are installed on the outer bracket 25.

[0055] A reset spring 28 connects the outer support 25 and the inner support 24.

[0056] Two pairs of upper racks 21 are connected as one unit via an inner bracket 24. Correspondingly, two pairs of lower racks 22 are connected as one unit via an outer bracket 25. When the outer opening / closing cam 29 pushes the opening / closing push rod 31 to extend, the opening / closing push rod 31 pushes the inner cam roller 26 and the outer cam roller 27 to move linearly. The inner cam roller 26 and the outer cam roller 27 drive the convex block 19 and the concave block 20 to open opposite each other via the inner bracket 24 and the outer bracket 25.

[0057] When the external opening and closing cam 29 drives the opening and closing push rod 31 to retract, since there is no external force at this time, only the force of the return spring 28 acts on the inner support 24 and the outer support 25. Therefore, the inner support 24 and the outer support 25 drive the convex block 19 and concave block 20 connected to them to move in the pressing direction, pressing the food sealing part of the dough into shape and continuously pressing it.

[0058] like Figure 3 As shown, the power source includes a motor, the main shaft of which is connected to an opening / closing cam 29. One end of the opening / closing cam 29 is connected to a cam rocker arm 30, and the other end of the cam rocker arm 30 is connected to an opening / closing push rod 31. The opening / closing cam 29 rotates with the main shaft of the motor, thereby pushing the cam rocker arm 30 to swing. The cam rocker arm 30 drives the push rod to move back and forth, which in turn pushes the inner cam roller 26 and the outer cam roller 27 on the molding die 5 through the opening / closing push rod 31, finally realizing the opening and closing movement of the compression molding block 10.

[0059] The end of the opening / closing push rod 31 is provided with a push plate 32. When the push plate 32 is provided, it is easier to push the inner cam roller 26 and the outer cam roller 27 on the forming mold 5 to move.

[0060] Four workstations are evenly arranged around the indexing plate 6. The four workstations are the dough receiving workstation 7, the filling and shaping workstation 8, the material unloading workstation 9, and the spare workstation. The spare workstation is a reserved workstation for edge trimming and shaping.

[0061] like Figure 4 As shown, this application only has one mold cup 4, which is installed at the filling station. The mold cup 4 is raised and lowered to different heights to cooperate with the molding mold 5 for forming.

[0062] The working process of the molding apparatus 3 in this application includes the following three main stages:

[0063] In the first stage, the mold cup 4 rises to its highest point (forming position), and the upper end of the mold cup 4 is level with the receiving plate 16. The forming head 34 of the filling device 2 moves downward, inserts the dough into the mold cup 4 to shape it, and then injects the filling.

[0064] Phase Two: The mold cup 4 descends to the middle point (pressing position). The mold cup 4 descends to the middle position, creating space for pressing and forming. At this time, the forming head 34 rises, disengaging from the mold cup 4 and the receiving plate 16. The convex block 19 and concave block 20 below the receiving plate 16 move in the pressing direction under the action of the opening and closing cam 29, pressing and forming the food sealing area.

[0065] Phase 3: The mold cup 4 descends to its lowest point (avoidance position). Once the mold cup 4 reaches its lowest position, it disengages from the food and the receiving plate 16. At this point, the forming block, under the tension of the return spring 28, clamps the already formed food. When the indexing plate 6 rotates, it carries the product away from the current workstation.

[0066] This application simplifies the structure of the forming mold 5. All forming molds 5 no longer have separate mold cups 4, but share the same mold cup 4. By combining filling and forming in one station, and then using the forming pressing block to remove the formed dumplings, the miniaturization of the machine under the encapsulation forming scheme is achieved, eliminating the need to design separate pressing and forming stations and mechanisms.

[0067] Because filling and shaping are combined at one station, the transition time between the two actions is very short, reducing intermediate steps and offering a significant advantage when handling dough with high moisture content and low toughness. The integrated design of the pressing block and forming mold allows the forming mold 5 to have product handling capabilities, eliminating the need for separate demolding or unloading mechanisms and simplifying the equipment. Unlike existing single-station forming solutions, the multi-station design gives operators more time to place the dough without needing to precisely follow the machine's rhythm, reducing labor intensity. The intermittent indexing plate at 6 stations facilitates integration with upstream and downstream automation needs, such as automatic dough loading and automatic plating in the catering industry.

[0068] The reserved workstation in this embodiment can easily expand the functions of forming, trimming, and cutting, reducing the requirements for the accuracy of the dough's appearance and placement, and expanding the product's applicability. For example, common round dough sheets can also be used on this equipment; after the food is formed, the excess dough can be cut off to obtain a standard finished product.
