Description

TECHNICAL FIELD

[0001] The utility model relates to food processing technical field, concretely relates to a height adjustable stirring structure and stirring device. BACKGROUND

[0002] In the food industry, stirring equipment is widely used in the factory production process of condiments and part dishes. Whether it is liquid condiment such as soy sauce, vinegar or semi-solid food material such as sauce, batter, stirring is the key step to ensure product quality and taste consistency. However, the traditional automatic stirring device usually adopts fixed height stirring blade, such as patent announcement no. CN218485751U a kind of stirring device for condiment production, patent announcement no. CN208809987U's cream, ghee production with raw material melting equipment, patent announcement no. CN205803423U an oil material steaming and frying device, patent announcement no. CN117598464A a kind of Tibetan medicine hot pot material formula, processing equipment and its processing technology, patent announcement no. CN221656368U a kind of seasoning oil mixing and blending equipment, etc. These patents and actual use with stirring function food stirring device have a common point that stirring blade height is not adjustable, which has many limitations in practical application:

[0003] First, different stirring tasks have different requirements for the insertion depth of stirring blade. For example, heavier raw materials need deeper insertion to ensure thorough mixing, while light or viscous materials may need shallower insertion depth to avoid excessive agitation leading to excessive bubbles.

[0004] Second, from the stirring efficiency and uniformity: in order to stir the material faster and more evenly, the insertion depth of stirring blade must be adjusted according to the specific situation. If inserted too deep or too shallow, it will affect the stirring effect, leading to uneven mixing or low efficiency.

[0005] Third, from the perspective of adapting to various application scenarios: in production, the same stirring equipment may be used to handle different types and weights of materials. Therefore, the stirring structure that can flexibly adjust the insertion depth of stirring blade is particularly important, which can significantly improve the versatility and work efficiency of the equipment. CONTENT OF THE UTILITY MODEL

[0006] The utility model intends to provide a height adjustable stirring structure to solve the problem of unadjustable stirring blade height in the current food processing stirring device.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A height-adjustable stirring structure includes a rotating shaft and stirring blades mounted on the rotating shaft. The rotating shaft includes a first section and a second section. The first section is fixedly connected to the output end of a rotating shaft drive motor. The stirring blades are mounted on the second section. The first section and the second section are sleeved together, and the second section is axially movable relative to the first section. The structure also includes a locking member for locking the relative position of the first section and the second section.

[0009] The principle and advantages of this solution are as follows: When it is necessary to adjust the height of the stirring blades according to different stirring tasks, the locking parts can be released from the first and second sections first. After the relative positions of the first and second sections are adjusted, the shaft length can be adjusted, which means that the height of the stirring blades in the container can be changed to adapt to the stirring requirements of different heights.

[0010] Preferably, as an improvement, it also includes a guide post for fixing inside the container. One of the second section and the guide post has a protrusion and the other has a groove. The protrusion can be inserted into the groove. There is a gap between the protrusion and the groove. This solution facilitates the adjustment of the shaft length. At the same time, the shaft is also guided by the guide post when it extends into the bottom of the container, ensuring the stability of the shaft rotation process.

[0011] Preferably, as an improvement, the stirring blades include upper and lower stirring blades located at different heights, with the distance between the upper stirring blade and the inner wall of the container being greater than the distance between the lower stirring blade and the inner wall of the container. The arrangement of upper and lower stirring blades at different heights in this solution results in higher stirring efficiency and more uniform stirring during the stirring process.

[0012] Preferably, as an improvement, the number of lower stirring blades is at least two, and each blade is arc-shaped. The arc-shaped stirring blades cause the distance between the stirring blades and the inner wall of the container to gradually change. The arc-shaped stirring blades reduce the resistance encountered during stirring and help to mix the raw materials evenly.

[0013] Preferably, as an improvement, the upper stirring blades are multiple inclined plates evenly distributed around the axis of rotation, which further helps to improve the uniformity of stirring.

[0014] Preferably, as an improvement, one of the first and second segments has a sleeve segment and the other has a shaft segment. The shaft segment is sleeved with the sleeve, and the locking element is a locking pin. The locking pin is threaded onto the sleeve and inserted into the sleeve to abut against the shaft segment. This solution achieves shaft length adjustment with a simple structure.

[0015] Preferably, as an improvement, the shaft segment is provided with at least one abutting surface, and the locking pin is used to abut against the abutting surface so that the locking pin has a sufficiently large abutting force on the shaft segment, ensuring that the shaft will not easily change length during use.

[0016] Preferably, as an improvement, the first and second segments are connected by a thread, and the locking element is a lock nut, which is threaded onto the shaft and used to lock the relative positions of the first and second segments. This solution provides another simple structure with an adjustable shaft length.

[0017] This utility model also provides a stirring device, including the height-adjustable stirring structure.

[0018] Preferably, as an improvement, it also includes a drive motor for rotating the shaft, a container and a container lid, the container being mounted on a support with casters, the drive motor being fixed to the container lid, and the container lid closing over the top opening of the container to facilitate the movement of the stirring device.

[0019] Preferably, as an improvement, the container is provided with a discharge port at the bottom. During the stirring process, the discharge port is sealed with other parts such as plugs or partitions, or a discharge valve is installed directly on the discharge pipe connected to the discharge port to prevent the raw materials from being discharged directly. After the stirring is completed, the discharge port is opened to facilitate the timely, quick and simple discharge of the stirred raw materials.

[0020] Preferably, as an improvement, a discharge pipe is installed on the discharge port, a discharge valve is installed on the discharge pipe, and a weighing device is installed at the output end of the discharge valve to facilitate weighing the finished product discharged after the agitator has finished mixing.

[0021] Preferably, as an improvement, the container lid is provided with a feeding port, and a sliding door or a feeding pipe is installed on the feeding port to facilitate the addition of raw materials into the container.

[0022] Preferably, as an improvement, the container lid is also equipped with a smoke exhaust pipe, which is used to connect to a fume extraction device so that if there is oil smoke during the stirring process, it can be directly and quickly discharged through the smoke exhaust pipe. Compared with an indoor range hood, this solution directly connects the smoke exhaust pipe to the container lid, which can quickly and accurately extract oil smoke, thereby reducing the energy consumption of the range hood.

[0035] The following detailed description illustrates the specific implementation method:

[0036] The reference numerals in the accompanying drawings include: rotating shaft 1, first section 11, second section 12, abutment surface 121, groove 122, locking element 13, stirring blade 2, drive motor 3, upper stirring blade 21, lower stirring blade 22, guide column 4, container 10, container cover 20, discharge port 101, bracket 30, moving wheel 301, discharge valve 40, weighing device 50, feeding port 201, sliding door 60, feeding pipe 70, and exhaust pipe 80.

[0037] Example 1

[0038] Combination Figures 1 to 8 A height-adjustable stirring structure includes a rotating shaft 1 and stirring blades 2 mounted on the rotating shaft 1, the length of which can be adjusted.

[0039] Specifically, the rotating shaft 1 includes a first section 11 and a second section 12. The first section 11 is used to be fixedly connected to the output end of the rotating shaft drive 3. The drive 3 is a drive motor 3, which is fixedly installed on the stirring device. The drive motor 3 is used to drive the rotating shaft 1 to rotate. The drive motor 3 may be a drive motor.

[0040] The stirring blade 2 is fixed on the second section 12 away from the drive motor 3. The first section 11 is sleeved with the second section 12, and the second section 12 can move axially relative to the first section 11. It also includes a locking member 13 for locking the relative position of the first section 11 and the second section 12.

[0041] Combination Figures 1 to 4 In one embodiment, the adjustable length of the rotating shaft 1 is specifically achieved as follows: the first segment 11 facing the second segment 12 is machined into a sleeve, the top of the second segment 12 is machined into a shaft segment, the shaft segment is sleeved with the sleeve, and a locking member 13, which is a locking pin, is threaded onto the sleeve. The locking pin is inserted into the sleeve and abuts against the shaft segment of the second segment 12. To improve the locking force of the locking pin on the shaft segment, the shaft segment is provided with at least one abutment surface 121. The shaft segment can be... Figure 2 The cylindrical shaft shown has an axial abutment groove, which can also be... Figure 3 The shaft segment is a polygonal structure (a regular hexagonal structure in the figure), and the sleeve and the polygonal cross section of the shaft segment are fitted together. When adjusting the length of the shaft 1, the locking pin is turned to release the locking pin from the second segment 12. Then, the second segment 12 is controlled to slide axially relative to the first segment 11, thereby adjusting the overall length of the shaft 1. After the length adjustment is completed, the locking pin is turned again to make the locking pin press against the inner wall of the sleeve of the second segment 12 and the first segment 11, thereby ensuring that the length of the shaft 1 will not change easily.

[0042] Combination Figure 5 and Figure 6 In another embodiment, the adjustable length of the rotating shaft 1 is specifically achieved as follows: the first segment 11 and the second segment 12 are connected by threads. The sleeve of the first segment 11 is provided with internal threads, and the shaft segment of the second segment 12 is provided with external threads. The locking element 13 is a locking nut, which is threaded onto the external threads. After the relative positions of the first segment 11 and the second segment 12 are adjusted, the length of the first segment 11 and the second segment 12 is locked by pressing the locking nut against the bottom end face of the first segment 11. When adjusting the length, the locking nut is first screwed away from the first segment 11, and then the second segment 12 is screwed to change the axial position of the second segment 12 relative to the first segment 11. After the adjustment is completed, the locking nut is screwed again until it abuts against the bottom end face of the first segment 11, thereby completing the locking of the length of the rotating shaft 1.

[0043] The stirring blade 2 includes an upper stirring blade 21 and a lower stirring blade 22 located at different heights. The distance between the upper stirring blade 21 and the inner wall of the container 10 is greater than the distance between the lower stirring blade 22 and the inner wall of the container 10. In a specific embodiment, the distance between the lower stirring blade 22 and the inner wall of the container 10 can be set to be no less than 1 mm. The distance between the upper stirring blade 21 and the inner wall of the container 10 is no less than 5 mm.

[0044] There are multiple lower stirring blades 22, which are evenly distributed around the rotation axis 1. Each lower stirring blade 22 is arc-shaped, and the arc shape of the lower stirring blade 22 makes the distance between the lower stirring blade 22 and the inner wall of the container 10 gradually change, reducing the difficulty of stirring when the lower stirring blade 22 is used.

[0045] There are multiple upper stirring blades 21, and these blades are evenly distributed around the rotating shaft 1. The upper stirring blades 21 are inclined plates.

[0046] Combination Figure 7 and Figure 8 In one embodiment, a guide post 4 is fixedly installed at the bottom of the container 10. The guide post 4 is coaxial with the rotating shaft 1 and is cylindrical. The cylindrical guide post 4 is equivalent to forming a circular protrusion. A groove 122 is machined at the bottom of the second section 12. The protrusion is inserted into the groove 122. There is a gap between the top surface of the protrusion and the bottom of the groove 122, so that even if the length of the rotating shaft 1 is adjusted, the bottom of the rotating shaft 1 is still limited by the guide post 4, ensuring that both ends are limited when the rotating shaft 1 rotates, thus ensuring the rotational stability of the rotating shaft 1.

[0047] In this embodiment, the adjustable length of the rotating shaft 1 is used to adapt to the stirring requirements of different stirring tasks, and the upper stirring blade 21 and the lower stirring blade 22 are set to make the stirring efficiency high and the stirring more uniform.

[0048] Example 2

[0049] Combination Figures 9 to 12 This embodiment 2 provides a stirring device, including a container 10, a container lid 20, and a height-adjustable stirring structure of embodiment 1. The position of the container 10 can be fixed, and the top of the container 10 is open. Specifically, the container 10 is a pot, a barrel, or a basin. The container lid 20 is closed on the container 10. The drive motor 3 that drives the rotating shaft 1 to rotate is fixedly installed on the top of the container lid 20. The rotating shaft 1 passes through the container lid 20 and extends into the container 10.

[0050] The container 10 is fixedly mounted on the support 30, and the bottom of the support 30 is equipped with casters 301 so that the stirring device can be easily moved.

[0051] The container 10 has a discharge port 101 at the bottom. During the stirring process, the discharge port 101 is sealed with other parts such as plugs or partitions, or a discharge valve 40 is installed directly on the discharge pipe connected to the discharge port 101. In this embodiment, the discharge pipe is installed on the discharge port 101 and the discharge valve 40 is installed on the discharge pipe as an example. A weighing device 50 is set at the output end of the discharge valve 40 to facilitate weighing the finished product discharged after the stirrer has finished stirring.

[0052] The container lid 20 is an arc-shaped cover, and a feeding port 201 is opened on the container lid 20. A sliding door 60 or a feeding pipe 70 is installed on the feeding port 201. Figure 9 and Figure 10 In the design, the feeding port 201 is a large opening on the side of the arc-shaped container lid 20. An arc-shaped sliding door 60 is installed on the large opening. The sliding door 60 is slidably connected to the container lid 20. When the sliding door 60 slides, it rotates around the center of the container lid 20, thus fully exposing the feeding port 501 after the sliding door 60 slides, facilitating feeding. Furthermore, the design of the sliding door 60, combined with the arc-shaped container lid 20, allows for a larger feeding port size, making feeding even more convenient. Figure 11 In the middle, a feeding pipe 70 is installed on the feeding port 201. The feeding pipe 70 can be connected to the pump body to facilitate the addition of raw materials into the container 10 by pumping, so as to facilitate automated feeding.

[0053] Combination Figure 12 In another improvement, a smoke exhaust pipe 80 is also installed on the container lid 20. The smoke exhaust pipe 80 is used to connect to the fume extraction equipment so that if there is oil smoke during the stirring process, it can be directly and quickly discharged through the smoke exhaust pipe 80. Compared with the range hood installed indoors, this solution directly connects the smoke exhaust pipe 80 to the container lid 20, which can quickly and accurately extract oil smoke, thereby reducing the energy consumption of the range hood.
