Description
Technical Field
[0001] This utility model belongs to the technical field of mooncake production equipment, specifically relating to a filling-wrapping device for mooncake production. Background Technology
[0002] Mooncakes, also known as moon cakes, harvest cakes, reunion cakes, etc., require filling equipment to wrap the fillings during the production and processing of mooncakes.
[0003] According to the patent announcement number CN218635176U, a mooncake filling equipment is known prior art. Although the patent has the advantage of adjusting the thickness of the mooncake skin according to production needs and improving versatility, the technical solution of the patent still has the following defects in actual use: the first auger and the second auger transport the filling and the dough respectively. The speed of the two rotating motors may not be synchronized, which may easily lead to the filling being pushed too fast or the dough supply being insufficient, resulting in incomplete wrapping (filling leakage) or excessive dough causing waste. In addition, the storage hopper has no anti-clogging structure. The mooncake dough is highly viscous and easily accumulates and clumps on the hopper wall, affecting the continuity of feeding and thus causing fluctuations in the thickness of the mooncake skin. Utility Model Content
[0004] The purpose of this invention is to provide a filling-wrapping device for mooncake production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a filling equipment for mooncake production, comprising an installation plate and a fixing plate, wherein a first feeding bin is fixedly connected to one side of the interior of the fixing plate, and a second feeding bin is fixedly connected to the other side of the interior of the fixing plate; The top of the mounting plate is provided with a conveying assembly, which includes a drive shaft and a motor. The outside of the drive shaft is rotatably connected to the inside of the mounting plate through a bearing, and the top of the drive shaft is fixedly connected to the bottom of the motor output shaft. A drive gear is fixedly connected to the outside of the drive shaft, and a driven gear is meshed with the side of the drive gear. A driven shaft is fixedly connected inside the driven gear. Both the first and second feeding bins are provided with stirring assemblies.
[0006] In a preferred embodiment, the driven shaft is rotatably connected to the inside of the mounting plate via a bearing, a limiting plate is fixedly connected to the top of the motor, and the bottom of the limiting plate is fixedly connected to the top of the mounting plate.
[0007] In a preferred embodiment, the stirring assembly includes two sets of stirring rods, one end of which is fixedly connected to the outside of the drive shaft and the driven shaft, respectively, and the other end of which is fixedly connected to two sets of scrapers.
[0008] In a preferred embodiment, the sides of the two sets of scrapers are in contact with the inner walls of the first and second feeding bins, respectively.
[0009] In a preferred embodiment, a fabric tube is fixedly connected to the bottom of the first feeding bin, a filling tube is fixedly connected to the bottom of the second feeding bin, a first conveying auger is fixedly connected to the outside of the drive shaft, and a second conveying auger is fixedly connected to the outside of the driven shaft.
[0010] In a preferred embodiment, the first conveying auger is located inside the fabric tube, the second conveying auger is located inside the filling tube, the fabric tube and the filling tube are connected, and a connecting tube is fixedly connected to the inner wall of the filling tube.
[0011] In a preferred embodiment, a plug plate is fixedly connected to the top of the fixing plate, the outside of the plug plate is inserted into the inside of the mounting plate, and a fixing bolt is threadedly connected to the side of the mounting plate, the outside of the fixing bolt is inserted into the inside of the plug plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This mooncake filling-wrapping equipment, through the installation of a conveying component, starts a motor. The motor's output shaft drives the drive shaft to rotate, and the drive gear on the outside of the drive shaft meshes with the driven gear, thereby driving the driven shaft to rotate synchronously. The drive shaft drives the first conveying auger in the fabric tube to rotate, and the driven shaft drives the second conveying auger in the filling tube to rotate, stably conveying the fabric in the first feeding bin and the filling in the second feeding bin to the corresponding pipelines. By using a single motor to drive the dual shafts, the speed of the fabric and filling conveying is synchronized, avoiding the speed imbalance problem that may occur with dual-motor drives. This effectively prevents filling leakage and uneven wrapping caused by excessively fast filling pushing or insufficient fabric supply. At the same time, it eliminates the need for a drive motor, significantly reducing the manufacturing cost and energy consumption of the equipment. This mooncake filling production equipment features a stirring assembly. When the drive and driven shafts rotate, they drive two sets of stirring rods to rotate synchronously. The scrapers at the ends of the stirring rods make close contact with and scrape the inner walls of the first and second feeding bins. The stirring rods continuously stir the dough and filling within the bins, while the scrapers remove material adhering to the bin walls. The stirring action of the stirring rods ensures a more uniform mixing of the filling in the second feeding bin, improving the consistency of the mooncake filling's texture. The scrapers effectively prevent material waste and blockage caused by dough adhering to the inner wall of the first feeding bin, while also reducing unsanitary corners within the bins and ensuring the cleanliness of food processing. This mooncake filling equipment uses insert plates and fixing bolts. After the filling operation is completed, the fixing bolts on the side of the mounting plate are loosened, allowing the fixing bolts to disengage from the insert plates. Then, the insert plate on top of the fixing plate can be pulled out from inside the mounting plate, separating the fixing plate from the mounting plate. This allows the fabric tube, filling tube, mounting plate, and conveying components to be completely separated. The process is simple and requires no complicated tools. It allows the fabric tube, filling tube, and feeding bin to be quickly separated from the main body of the equipment, facilitating thorough cleaning of the inside of the pipes, bins, and mixing components by the operators. This prevents residual materials from breeding bacteria, ensuring food processing hygiene, and reducing the labor intensity of equipment maintenance. Attached Figure Description

Detailed Implementation
[0015] The present invention will be further described below with reference to the embodiments.
[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0017] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a filling-filling device for mooncake production, including a mounting plate 1 and a fixing plate 11. A first feeding bin 7 is fixedly connected to one side of the interior of the fixing plate 11, and a second feeding bin 8 is fixedly connected to the other side of the interior of the fixing plate 11. A conveying assembly is provided on the top of the mounting plate 1. The conveying assembly includes a drive shaft 2 and a motor 15. The outside of the drive shaft 2 is rotatably connected to the inside of the mounting plate 1 through a bearing, and the top end of the drive shaft 2 is fixedly connected to the bottom end of the output shaft of the motor 15. A drive gear 3 is fixedly connected to the outside of the drive shaft 2, and a driven gear 14 is meshed with the side of the drive gear 3. A driven shaft 4 is fixedly connected inside the driven gear 14. The first feeding bin 7 and the second feeding bin 8 are connected to the first feeding bin 7 and the second feeding bin 8. The inside of each hopper 8 is equipped with a stirring assembly. The external of the driven shaft 4 is rotatably connected to the inside of the mounting plate 1 via a bearing. The top of the motor 15 is fixedly connected to a limit plate 19, and the bottom of the limit plate 19 is fixedly connected to the top of the mounting plate 1. The bottom of the first feeding hopper 7 is fixedly connected to a fabric tube 5, and the bottom of the second feeding hopper 8 is fixedly connected to a filling tube 6. The external of the drive shaft 2 is fixedly connected to a first conveying auger 16, and the external of the driven shaft 4 is fixedly connected to a second conveying auger 17. The first conveying auger 16 is located inside the fabric tube 5, and the second conveying auger 17 is located inside the filling tube 6. The fabric tube 5 and the filling tube 6 are connected. The inner wall of the filling tube 6 is fixedly connected to a connecting pipe 18.
[0018] In this embodiment, after the mooncake dough is put into the first feeding bin 7 and the mooncake filling is put into the second feeding bin 8, the motor 15 is started. The output shaft of the motor 15 drives the drive shaft 2 to rotate around the bearing inside the mounting plate 1. The drive gear 3 outside the drive shaft 2 meshes precisely with the driven gear 14, thereby driving the driven shaft 4 to rotate synchronously, realizing the linkage drive of the single motor 15 to the two shafts. The drive shaft 2 drives the first conveying auger 16 in the dough tube 5 to rotate, and the driven shaft 4 drives the second conveying auger 17 in the filling tube 6 to rotate, so that the mixed dough and filling are stably conveyed downward along the pipeline.
[0019] The dough is pushed to the bottom of the dough tube 5 by the first conveying auger 16, and the filling is pushed to the bottom of the filling tube 6 by the second conveying auger 17. Through the connection structure between the dough tube 5 and the filling tube 6 and the guide of the connecting tube 18 on the inner wall of the filling tube 6, the dough is evenly wrapped around the outside of the filling, completing the mooncake filling and shaping operation.
[0020] By precisely meshing the drive gear 3 and the driven gear 14, the drive shaft 2 and the driven shaft 4 rotate synchronously, ensuring that the speeds of the first conveying auger 16 and the second conveying auger 17 are perfectly matched. This avoids the speed imbalance problem that may occur with traditional dual-motor drive, effectively preventing quality defects such as filling leakage and uneven wrapping caused by excessively fast filling or insufficient dough supply, and ensuring the consistency and pass rate of mooncake filling formation. At the same time, only a single motor 15 is needed to complete the dual-path material conveying drive, eliminating the need for an additional drive motor 15, significantly reducing the manufacturing cost of the equipment, reducing energy consumption during operation, and improving the economic efficiency of the equipment.
[0021] Please see Figure 1 and Figure 2 The mixing assembly includes two sets of mixing rods 9. One end of each set of mixing rods 9 is fixedly connected to the outside of the drive shaft 2 and the driven shaft 4, respectively. The other end of each set of mixing rods 9 is fixedly connected to two sets of scrapers 10. The sides of the two sets of scrapers 10 are in contact with the inner walls of the first feeding bin 7 and the second feeding bin 8, respectively.
[0022] In this embodiment, the drive shaft 2 drives the stirring rod 9 and scraper 10 in the first feeding chamber 7 to rotate, and the driven shaft 4 drives the stirring rod 9 and scraper 10 in the second feeding chamber 8 to rotate. The scraper 10 makes close contact with the inner wall of the feeding chamber and scrapes continuously, stirring the dough and filling in the chamber. The continuous stirring of the materials in the chamber by the stirring rod 9 makes the filling in the second feeding chamber 8 more evenly mixed, avoiding the agglomeration of particulate components in the filling and ensuring the consistency of taste and quality of mooncake fillings in different batches. The close scraping between the scraper 10 and the inner wall of the feeding chamber can thoroughly remove the dough adhering to the inner wall of the first feeding chamber 7, reducing material waste and avoiding material accumulation that causes blockage in the feeding process, ensuring the smooth conveying of dough and filling. In addition, the scraping action reduces the number of dead corners in the chamber, reduces the risk of bacteria growth from residual materials, and improves the cleanliness of the food processing process.
[0023] Please see Figure 1 and Figure 4 A plug plate 12 is fixedly connected to the top of the fixing plate 11. The outside of the plug plate 12 is inserted into the inside of the mounting plate 1. A fixing bolt 13 is threadedly connected to the side of the mounting plate 1. The outside of the fixing bolt 13 is inserted into the inside of the plug plate 12.
[0024] In this embodiment, after the filling operation is completed, the fixing bolt 13 is loosened to disengage from the insertion hole of the insert plate 12, and the insert plate 12 is pulled out from the inside of the mounting plate 1, realizing the rapid separation of the fixing plate 11 and the mounting plate 1. This allows for the disassembly of the fabric tube 5, the filling tube 6, and the conveying assembly, facilitating a thorough cleaning of each component and preparing for the next operation. The assembly design of the insert plate 12 and the fixing bolt 13 makes the disassembly of the fixing plate 11 and the mounting plate 1 simple and convenient, requiring no complicated tools and saving equipment disassembly time. It also facilitates thorough cleaning by operators, completely removing residual materials from the pipes and the chamber, ensuring the hygiene and safety of food processing, and avoiding cross-contamination.
[0025] In the above scheme, it should be noted that: the motor 15 in this application is an existing product, and the specific structure, circuit connection method (circuit layout) and working principle of the motor 15 are all existing publicly disclosed technical means. At the same time, the motor 15 can be turned on or off manually, which is also an existing publicly disclosed technical means, and will not be described in detail here.
[0026] The working principle and usage process of this utility model are as follows: First, put the mooncake dough into the first feeding bin 7, put the mooncake filling into the second feeding bin 8, start the motor 15, and the output shaft of the motor 15 drives the drive shaft 2 to rotate around the bearing inside the mounting plate 1. The drive gear 3 outside the drive shaft 2 meshes precisely with the driven gear 14, thereby driving the driven shaft 4 to rotate synchronously, realizing the linkage drive of the single motor 15 to the two shafts. During the dual-axis rotation, two sets of actions are triggered simultaneously: On the one hand, the drive shaft 2 drives the stirring rod 9 and scraper 10 in the first feeding bin 7 to rotate, and the driven shaft 4 drives the stirring rod 9 and scraper 10 in the second feeding bin 8 to rotate. The scraper 10 is in close contact with the inner wall of the feeding bin to scrape and continuously stir the fabric and filling in the bin; on the other hand, the drive shaft 2 drives the first conveying auger 16 in the fabric tube 5 to rotate, and the driven shaft 4 drives the second conveying auger 17 in the filling tube 6 to rotate, so that the stirred fabric and filling are stably conveyed downward along the pipeline respectively. The fabric is pushed to the bottom of the fabric tube 5 by the first conveying auger 16, and the filling is pushed to the bottom of the filling tube 6 by the second conveying auger 17. Through the connection structure between the fabric tube 5 and the filling tube 6 and the guide of the connecting tube 18 on the inner wall of the filling tube 6, the fabric is evenly wrapped around the outside of the filling, completing the mooncake filling and shaping operation. After the filling operation is completed, loosen the fixing bolt 13 so that the fixing bolt 13 is disengaged from the insertion hole of the insert plate 12, and pull the insert plate 12 out from the inside of the mounting plate 1 to achieve quick separation of the fixing plate 11 and the mounting plate 1. Then, disassemble the fabric tube 5, the filling tube 6 and the conveying assembly to facilitate a thorough cleaning of each component and prepare for the next operation.
[0027] In the above scheme, it should be noted that: the bottom end of the filling tube 6 of this application is provided with an existing pastry cutting device (this is a publicly disclosed technical means) for cutting and closing the top of the mooncake falling from the bottom end of the filling tube 6.
