[0002] Dumplings, a traditional Chinese delicacy, are loved by many. Meat grinders are key equipment in the dumpling processing, and their performance directly affects the quality of the meat filling and the overall quality of the dumplings.
[0003] In the early stages of dumpling processing, the meat grinding process relied heavily on manual labor. Workers used traditional knives to chop fresh meat, a method that was not only extremely labor-intensive but also inefficient, making it difficult to meet the demands of large-scale production. Furthermore, manual chopping made it difficult to ensure the uniformity of the meat filling; different batches of filling could vary significantly in particle size and texture, thus affecting the taste and quality consistency of the dumplings. Currently, simple mechanical meat grinders have gradually appeared on the market. These grinders typically employ a single spiral conveyor shaft structure, which, while improving grinding efficiency and reducing manual labor to some extent, still has many shortcomings. For example, due to an inadequately designed conveyor structure, fresh meat is prone to blockages and accumulation during transport, leading to uneven conveying and affecting the continuity of grinding. Therefore, this application proposes a meat grinder for dumpling processing. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This embodiment provides a meat grinder for dumpling processing, the structural schematic diagram of which is shown below. Figures 1-5 As shown, the equipment includes a base 1, a meat grinder 2, and a feed cylinder 6. The base 1 is made of sturdy metal to ensure the stability of the equipment during operation. The meat grinder 2 is horizontally positioned above the base 1, and a bracket 8 is fixedly installed on the base 1 to further support the meat grinder 2 and enhance the overall structural stability.
[0028] In this embodiment, a winch 4 is threaded onto one end of the meat grinder 2 via a connecting ring seat 5. The winch 4 is fixed to the end of the meat grinder 2 via the connecting ring seat 5 for easy disassembly and cleaning. A cross blade 13 is provided inside the meat grinder 2 facing the winch 4. A first spiral conveying shaft 12 is also provided inside the meat grinder 2. The first spiral conveying shaft 12 is coaxially connected to the cross blade 13. The spiral blade design of the first spiral conveying shaft 12 can effectively convey fresh meat toward the cross blade 13 and the winch 4. The winch 4 is provided with multiple blade holes for mincing fresh meat. When the fresh meat passes through the winch 4, it is minced into meat paste under the action of the cross blade 13. A first drive motor 3 is installed on the base 1. A reducer 10 and a coupling 11 are assembled between the output shaft of the first drive motor 3 and the first spiral conveying shaft 12. The speed reducer 10 is used to reduce the speed of the first drive motor 3 and increase the torque to meet the power requirements during the meat grinding process; the coupling 11 serves to connect the output shaft of the first drive motor 3 and the first screw conveyor shaft 12 to ensure that the power can be transmitted stably.
[0029] Furthermore, in this embodiment, the meat grinder 2 is configured as a conical structure, with the end with the smaller end radius facing the first drive motor 3. The size of the first spiral conveying shaft 12 is adapted to the meat grinder 2. This conical structure design allows the fresh meat to be more easily minced into meat filling as the diameter of the cylinder gradually increases during the conveying process inside the meat grinder 2, which is beneficial to improving the meat grinding effect.
[0030] Furthermore, in this embodiment, a feeding hopper 7 is provided at the top end of the meat grinder 2 away from the winch 4, and the feeding hopper 7 is connected to the interior of the meat grinder 2. The feeding cylinder 6 is fixed to the top of the feeding hopper 7 and is connected to the meat grinder 2 through the feeding hopper 7. A second spiral conveying shaft 17 is provided at the bottom of the feeding cylinder 6. The radius of the second spiral conveying shaft 17 gradually decreases from top to bottom, and its bottom end extends into the feeding hopper 7. This design helps to smoothly convey the fresh meat in the feeding cylinder 6 into the meat grinder 2.
[0031] Furthermore, a support plate 15 is horizontally fixed at the top of the feed cylinder 6, and a shaft 14 extending into the feed cylinder 6 is vertically rotatably mounted at the bottom of the support plate 15. The second spiral conveying shaft 17 is coaxially connected to the bottom end of the shaft 14. The second drive motor 16 is fixedly mounted on the support plate 15, and its output shaft is coaxially connected to the shaft 14 to drive the second spiral conveying shaft 17 to rotate.
[0032] Furthermore, in this embodiment, a controller 9 is provided on the base 1, and the controller 9 is connected to the first drive motor 3 and the second drive motor 16. The controller 9 can conveniently control the start, stop, and speed adjustment of the first drive motor 3 and the second drive motor 16, thereby realizing automated control of the meat grinding process.
[0033] Working principle:
[0034] When using this meat grinder for dumpling processing, fresh meat is first placed into the feed cylinder 6, and then the second drive motor 16 is started via the controller 9. The second drive motor 16 drives the shaft 14 to rotate, which in turn drives the second spiral conveyor shaft 17 to rotate. Since the radius of the second spiral conveyor shaft 17 gradually decreases from top to bottom and its bottom end extends into the feed hopper 7, the fresh meat is gradually conveyed downwards by the second spiral conveyor shaft 17 and enters the meat grinder cylinder 2 through the feed hopper 7. At the same time, the first drive motor 3 is started via the controller 9. The output shaft of the first drive motor 3 is reduced in speed by the reducer 10 and transmitted through the coupling 11, driving the first spiral conveyor shaft 12 to rotate. The first spiral conveyor shaft 12 conveys the fresh meat entering the meat grinder cylinder 2 towards the cross blade 13 and the winch 4. When the fresh meat reaches the cross blade 13, it is initially minced under the high-speed rotation of the cross blade 13, and then continues to be conveyed to the winch 4, where it is further minced into meat filling that meets the requirements, and finally squeezed out from the blade holes of the winch 4, completing the meat grinding process.
[0035] All technical features in this embodiment can be freely combined according to actual needs.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
