[0002] Food additives are compounds or natural substances added to food to improve its color, aroma, and flavor, as well as for preservation and processing needs. China has 23 categories and over 2,000 varieties of food additives, including acidity regulators, anti-caking agents, defoamers, antioxidants, and bleaching agents. The rational use of food additives can prevent food spoilage, maintain or enhance its nutritional value, and improve or enrich its color, aroma, and flavor. Currently, some food additives require uniform mixing during processing.

[0023] 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.

[0024] Please see Figures 1 to 3This embodiment of a food additive mixing device includes a tank 1 for mixing food additives and a stirring rod 2. A drive mechanism for driving the stirring rod 2 is provided on the upper surface of the tank 1. Specifically, the drive mechanism includes a transmission sleeve 4 rotatably mounted inside the tank 1, a transmission shaft 5 splinedly connected inside the transmission sleeve 4, a first drive motor 6 fixed to the upper surface of the tank 1, and a first transmission assembly 7 disposed on the output shaft of the first drive motor 6 and the transmission sleeve 4. This assembly can transmit rotational torque and allow the transmission shaft 5 to move axially, such as freely moving up and down, thus not affecting the rotational drive of the stirring rod 2, while also supporting its reciprocating motion. The bottom end of the transmission shaft 5 extends into the tank 1 and connects to the flange at the top of the stirring rod 2, facilitating disassembly, cleaning, or replacement of the mixing components. A feeding pipe 8 is rotatably connected to the top of the stirring rod 2, and several spray holes 3 are opened inside the stirring rod 2. Liquid additives can be dynamically sprayed in during the mixing process through the feeding pipe 8, avoiding local accumulation and improving mixing uniformity.

[0025] In this embodiment, a rotating hole is provided inside the tank body 1, and the transmission sleeve 4 is fixed in the rotating hole by bearings. The upper and lower ends of the transmission sleeve 4 are connected. The transmission shaft 5 passes through the inside of the transmission sleeve 4, and the first transmission assembly 7 consists of a worm gear and a worm. The worm gear is fixed to the outer surface of the transmission sleeve 4, and the worm is fixed to the output shaft of the first drive motor 6.

[0026] To improve the mixing effect, a reciprocating mechanism 9 for reciprocating the stirring rod 2 is also provided on the upper surface of the tank body 1. The reciprocating mechanism 9 includes a mounting bracket 901 fixed to the upper surface of the tank body 1, a turntable 903 and a slide 904 disposed outside the mounting bracket 901, and a drive structure disposed outside the mounting bracket 901 for driving the turntable 903. A rolling element is disposed between the turntable 903 and the slide 904. The drive structure includes a rotating shaft 902 rotatably mounted inside the mounting bracket 901, a second drive motor 908 fixed to the side of the mounting bracket 901 away from the turntable 903, and a second transmission assembly 909 disposed at the end of the rotating shaft 902 and on the output shaft of the second drive motor 908.

[0027] Specifically, the second transmission assembly 909 consists of two meshing gears. The end of the rotating shaft 902 away from the gears passes through the mounting bracket 901 and is fixed to the back of the turntable 903. One of the gears is fixedly mounted on the output shaft of the second drive motor 908, and the other gear is fixedly mounted on one end of the rotating shaft 902. The rolling element includes a connecting shaft 905 fixed to the side of the turntable 903 away from the rotating shaft 902, and a roller 906 with a bearing mounted on the other end of the connecting shaft 905 and rollingly connected to the inside of the slide 904. The slide 904 has a groove 907 inside that matches the roller 906, and the roller 906 is rollingly connected to the inner wall of the groove 907. While the stirring rod 2 rotates under the drive mechanism, the reciprocating mechanism 9 moves it up and down, forming a three-dimensional stirring effect, effectively breaking up stirring dead zones, especially suitable for mixing high-viscosity, easily sedimented food additives. The top end of the transmission shaft 5 is rotatably connected to the inside of the slide 904.

[0028] To ensure stable reciprocating lifting and lowering of the drive shaft 5, a limiting structure for guiding the drive shaft 5 is provided between the mounting bracket 901 and the slide 904. The limiting structure includes a guide rod 910 fixed to the upper surface of the slide 904 and a buffer spring 911. The other end of the buffer spring 911 is fixed to the outer surface of the mounting bracket 901, and the guide rod 910 penetrates the interior of the mounting bracket 901. It should be noted that the guide rod 910 ensures that the slide 904 moves only in the vertical direction, preventing the drive shaft 5 from swaying. Simultaneously, the buffer spring 911 absorbs the impact force of the reciprocating motion, reducing vibration and protecting the motor and transmission components. The length of the guide rod 910 and the deformation distance of the buffer spring 911 are matched to the reciprocating distance of the stirring rod 2.

[0029] The working principle of the above embodiments is as follows:

[0030] First, the first drive motor 6 drives the transmission sleeve 4 to rotate through the first transmission assembly 7. The transmission sleeve 4 transmits power to the transmission shaft 5 through a spline connection, thereby driving the stirring rod 2 to rotate and achieve the mixing of food additives in the tank. The spray hole 3 inside the stirring rod 2 is connected to the feeding pipe 8, which can spray liquid additives simultaneously during the stirring process to achieve dynamic mixing.

[0031] Next, the second drive motor 908 drives the rotating shaft 902 to rotate via the second transmission assembly 909, which in turn drives the turntable 903 to rotate. The turntable 903 is connected to the roller 906 via the connecting shaft 905. The roller 906 rolls in the slide groove 907 and pushes the slide 904 to reciprocate in the horizontal direction. At this time, the slide 904 drives the transmission shaft 5 and the stirring rod 2 to move up and down as a whole, expanding the stirring range and enabling the stirring rod 2 to rotate and reciprocate up and down at the same time, which significantly improves the uniformity of mixing.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
