Description

Technical Field

[0001] This utility model relates to the field of screw conveyor structures, and more particularly to a lightweight improved feeding screw structure. Background Technology

[0002] In the food processing industry, meat product manufacturing occupies a pivotal position. Meat products not only provide a rich variety of culinary choices for people's tables but also play an important role in nutritional supplementation and flavor enhancement. However, the manufacturing process of meat products is not simply about cutting and seasoning meat; it involves multiple complex technological steps and precise technical requirements. Meat grinding includes steps such as raw material pretreatment, cutting, mincing, mixing, and shaping. Raw material pretreatment mainly removes impurities and tendons from the meat to ensure the purity of the minced meat. Cutting involves cutting the meat into appropriately sized pieces for easier mincing. Mincing involves pulverizing the meat pieces through the blades of a meat grinder to form a uniform meat filling. Mixing involves incorporating various seasonings and additives into the meat filling to enhance texture and flavor. Finally, shaping equipment forms the meat filling into meat products of various shapes and sizes.

[0003] Existing meat grinders typically use an auger to transport meat chunks to a perforated disc for discharge, forming granular or strip-shaped minced meat. However, existing augers are quite heavy, making them difficult for drive motors to operate. Therefore, there is an urgent need for a more rationally designed auger structure to overcome the aforementioned technical drawbacks. Utility Model Content

[0004] To address the technical problem that the existing auger structure has a large overall weight and places high load requirements on the drive motor, this utility model provides a solution.

[0005] To achieve the above objectives, this utility model provides a lightweight improved feeding screw structure, including a first component and a second component. Both the first component and the second component have exposed semi-cavities, and they are joined together with the side having the semi-cavities to form an integral central shaft. The outside of the central shaft is formed with auger blades for conveying materials.

[0008] As an improvement to this application, the auger blades are designed with continuously arranged threads.

[0009] As an improvement of this application, the two opposite ends of the central shaft form an inlet end and an outlet end, wherein the thread pitch of the inlet end is greater than the thread pitch of the outlet end.

[0010] As an improvement of this application, the cross-sectional diameter of the central shaft gradually increases from the feed end to the discharge end.

[0011] As an improvement of this application, the two ends of the central shaft are further provided with openings, which are connected to the cavity enclosed by the two semi-cavities.

[0012] As an improvement of this application, the opposing sides of the first component and the second component are also provided with alignment protrusions and alignment recesses.

[0013] As an improvement of this application, the alignment recess and the alignment protrusion are provided in at least two sets, and are respectively located at both ends of the first part and the second component.

[0014] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model provides a lightweight improved feeding screw structure, including a first component and a second component. Both the first component and the second component are provided with exposed semi-cavities, and the sides with the semi-cavities are combined with each other to form an integral central shaft. The outside of the central shaft is formed with auger blades for conveying materials.

[0023] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0024] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are merely one part of the present invention, and not all of the embodiments. It should be understood that the specific embodiments described are only for explaining the present invention and are not intended to limit the present invention.

[0025] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0026] Existing meat grinders typically use an auger to convey meat chunks to a perforated disc for discharge, forming granular or strip-shaped minced meat. However, existing augers are generally heavy, making them difficult to drive with a motor. To address these technical problems, this application provides a lightweight, improved feeding screw structure. Please refer to the attached diagram. Figure 1 To be continued Figure 4 It includes a first component 1 and a second component 2. Both the first component 1 and the second component 2 are provided with an exposed semi-cavity a, and they are joined together with the side provided with the semi-cavity a to form a central shaft as a whole; the outside of the central shaft is formed together with auger blades 3 for conveying materials.

[0027] In this embodiment, the first component 1 and the second component 2 can be connected by laser welding, argon arc welding, gas welding, or other welding modes combined together; the central shaft formed by the first component 1 and the second component 2 corresponds to the shaft of the auger in the prior art, and the design based on the semi-cavity a reduces the weight of the auger structure. Under the same size design, the weight of the auger under the traditional structure casting is 478g, while the weight under the structure design of this application is 200g, which reduces the weight by 60%. During use, it can reduce the driving pressure of the drive motor, and can better achieve rotation to obtain better and stronger propulsion.

[0028] In this embodiment, the wall thickness of the first component 1 and the second component 2 is between 1.8-3.0 mm, preferably 2.5 mm. Under this wall thickness parameter, a balance can be achieved in terms of strength and weight reduction, which is more in line with the actual application scenario of this application.

[0029] In this embodiment, both the outer walls of the first component 1 and the second component 2 are provided with blade assemblies, which are integrally formed with the corresponding components; the two blade assemblies form the auger blades 3; it is worth noting that the first component 1 is provided with a blade assembly, referred to as the first blade assembly 3a, which is integrally formed with the first component 1; the second component 2 is provided with a blade assembly, referred to as the second blade assembly 3b, which is also integrally formed with the second component 2; when the first component 1 and the second component 2 are connected together by welding, the first component 1 and the second component 2 form a central axis, and the first blade assembly 3a and the second blade assembly 3b form the auger blades 3 located on the central axis. The auger blades 3, driven by the drive motor, transport materials. The type of materials can be different kinds of food raw materials based on different implementation products such as meat grinders, food processors, etc., and is not specifically limited here.

[0030] In a further embodiment, the auger blades 3 feature a continuously threaded design. Since there are no obvious partitions, material conveying is more efficient and smoother. In an even better embodiment, the two ends of the central shaft form an inlet end c and an outlet end b. The thread pitch at the inlet end c is greater than that at the outlet end b. This thread pitch design significantly improves the material feeding and conveying capacity. In a further preferred embodiment, the cross-sectional diameter of the central shaft gradually increases from the inlet end c towards the outlet end b. This design allows for better material entry, and the different diameters create a guiding function in the inclined middle section, enabling rapid material discharge and smoother rotation.

[0031] In this embodiment, openings are provided at both ends of the central shaft to communicate with the cavity enclosed by the two semi-cavities a. The openings facilitate the connection of the drive motor and the stabilizing shaft in the actual product and make it easier for technicians to implement the product.

[0032] In this embodiment, the opposing sides of the first component 1 and the second component 2 are also provided with a corresponding alignment protrusion e and an alignment recess f. It is easy to understand that the alignment protrusion e and the alignment recess f can fit together, which can greatly alleviate the movement of the first component 1 and the second component 2 during the welding process, making the welding more precise and convenient. In a more preferred embodiment, the alignment recess e and the alignment protrusion f are provided in at least two sets, and are respectively placed at both ends of the first component 1 and the second component 2, which can significantly improve the initial bonding ability and make the welding process more convenient.

[0033] The advantages of this utility model are:

[0034] Based on modular design, the corresponding half-cavities are opened and then combined to form the central shaft structure, which can reduce the weight by 60% and greatly reduce the driving pressure of the drive motor, thus achieving better material propulsion force in use.

[0035] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
