[0021] like Figures 1 to 5 As shown, a food production stirring device provided in an embodiment of the present invention is used to stir food raw materials; in this embodiment, the food production stirring device is configured to include a stirring barrel 100, a stirring fan blade 200 and an adjustment mechanism, specifically, as Figure 1 As shown, the mixing barrel 100 is configured as a barrel-shaped structure with an open top. A barrel cover 110 is detachably connected to the top of the mixing barrel 100 by bolts. The barrel cover 110 is configured as a circular plate-shaped structure. The barrel cover 110 is configured to open and close the top opening of the mixing barrel 100, so as to facilitate the installation and maintenance of the mixing blades 200 and the adjustment mechanism on the one hand, and to prevent foreign dust from entering the mixing barrel 100 from the top opening of the mixing barrel 100 during mixing, thereby preventing the raw materials from being contaminated. More specifically, a support leg 120 is provided at the bottom of the mixing barrel 100, and the support leg 120 is used for support. More specifically, as shown in FIG. Figure 1 and Figure 2 As shown, a feed port 101 and a discharge port 102 are arranged in parallel on the circumferential side wall of the mixing barrel 100, and the feed port 101 is located above the discharge port 102, wherein the feed port 101 is used to receive food raw materials, and the discharge port 102 is used to discharge the mixed food.

[0022] It is understandable that there may be a plurality of support legs 120 , which may be evenly arranged along a circumferential direction at the bottom of the mixing barrel 100 , so as to better support the mixing barrel 100 ; for example, there may be three support legs 120 .

[0023] like Figure 4 As shown, there are multiple stirring blades 200, which are arranged inside the stirring barrel 100 along the circumferential direction. Each stirring blade 200 has a central axis 210 and a spiral blade 220. One end of the central axis 210 is ball-hinged at the bottom of the stirring barrel 100, and the other end is arranged at the top of the stirring barrel 100 and can slide in the radial direction of the stirring barrel 100. The spiral blade 220 is arranged on the central axis 210 in an axial direction and in a spiral shape; each stirring blade 200 can rotate on its own; for example, there can be three stirring blades 200, which are arranged to be evenly arranged inside the stirring barrel 100 along the circumferential direction.

[0024] The stirring blade 200 is configured to have a first state and a second state. When in the first state, Figure 4 As shown, the axis of the central shaft 210 is arranged parallel to the axis of the mixing barrel 100. When in the second state, as shown in FIG. Figure 5 As shown, there is a preset angle between the axis of the central shaft 210 and the axis of the mixing barrel 100, and all the axes of the central shaft 210 intersect at the same point; the adjustment mechanism is configured to enable the mixing blade 200 to switch between the first state and the second state.

[0025] The reason why the stirring fan blade 200 is configured to have a first state and a second state is that when the stirring fan blade 200 is always in the first state or the second state, the food raw materials will gradually form a relatively fixed and orderly movement path, resulting in the food raw materials in different areas being able to contact and mix with each other more regularly only in their respective areas, which in turn leads to the inability to fully interact between the food raw materials in each area, causing the mixing efficiency to stagnate at a certain level or even decrease, and failing to achieve a more ideal uniform mixing state.

[0026] Therefore, in order to ensure both the stirring effect and the mixing efficiency, the stirring blade 200 is configured to continuously switch between the first state and the second state, so that the food raw materials are always in a state of turbulent and disordered flow driven by the stirring blade 200.

[0027] In the process of stirring the food raw materials, firstly, the food raw materials are introduced into the stirring barrel 100 through the feed port 101, and then all the stirring blades 200 are driven to rotate around their own axes to stir the raw materials. In the process of the stirring blades 200 rotating, the stirring blades 200 synchronously drive the spiral blades 220 to rotate, and the spiral blades 220 synchronously drive the raw materials to rotate while moving along the axial direction of the central axis 210 from bottom to top, so that the raw materials can be mixed not only in the circumferential direction, but also in the axial direction, which helps to improve the mixing effect of the raw materials. The stirring blade 200 is switched between the first state and the second state through the adjustment mechanism to stir the raw materials. During the state switching of the stirring blade 200, the central axis 210 switches back and forth between the vertical state and the inclined state. The central axis 210 synchronously drives the spiral blade 220 to move, so that not only the spiral blade 220 can stir the raw materials in the radial direction, but also the raw materials can move to the same point to converge and collide under the drive of different spiral blades 220, thereby helping to further improve the mixing effect of the raw materials and improve the mixing efficiency of the raw materials.

[0028] After the mixing is completed, the food can be taken out from the mixing barrel 100 through the discharge port 102 .

[0029] In some embodiments, a partition 130 is further provided inside the mixing barrel 100, and the partition 130 is configured to separate the adjustment mechanism and the mixing blade 200. Specifically, Figure 4 As shown, the partition 130 is configured as a circular plate structure and is coaxially inserted into the mixing barrel 100. The adjustment mechanism and the mixing blades 200 are respectively located at the upper and lower ends of the partition 130 during installation, thereby preventing the raw materials from splashing onto the adjustment mechanism during the mixing process and affecting the adjustment performance of the adjustment mechanism.

[0030] In some embodiments, the adjustment mechanism is configured to include a transmission component and a guide component, wherein the transmission component is configured to drive the central axis 210 to move in the radial direction of the mixing barrel 100 ; the guide component is configured to guide the central axis 210 to move in the radial direction of the mixing barrel 100 .

[0031] In this embodiment, the transmission assembly is configured to include a center disk 410, a first hinge rod 420 and a second hinge rod 430. The center disk 410 is coaxially disposed inside the mixing barrel 100 and can rotate around its own axis. Specifically, Figure 3 As shown, the center plate 410 is coaxially arranged on the top of the partition 130; the first end of the first hinge rod 420 is coaxially and fixedly connected to the center plate 410, and the second end is hinged to the first end of the second hinge rod 430, and the second end of the second hinge rod 430 is hinged to the center shaft 210. Specifically, as shown in FIG. Figure 4As shown, the first hinge rod 420 is configured as a rod-shaped structure, and a plurality of the first hinge rods 420 are configured and are configured one by one with the stirring blades 200. The plurality of first hinge rods 420 are configured on the center disk 410 along the circumferential direction on the one hand, and are stacked along the axial direction of the center disk 410 on the other hand. The first end of each first hinge rod 420 is fixedly connected to the center disk 410, and the second end is suspended. More specifically, as Figure 4 As shown, the second hinged rod 430 is configured as a rod-shaped structure, and there are multiple of them, and they are arranged one-to-one corresponding to the first hinged rod 420. Taking a second hinged rod 430 as an example, the first end of the second hinged rod 430 is hinged to the second end of the corresponding first hinged rod 420, and the second end of the second hinged rod 430 is sleeved on a central axis 210 and can rotate relatively.

[0032] For example, when the number of stirring blades 200 is set to three and they are arranged evenly in the circumferential direction inside the stirring barrel 100, the number of first hinged rods 420 is correspondingly set to three and they are arranged evenly in the circumferential direction on the center disk 410, and the number of second hinged rods 430 is also correspondingly set to three and they are arranged one-to-one with the first hinged rods 420.

[0033] In this embodiment, the guide assembly is configured to include an equal number of guide rails 141 and guide blocks 142. The number of guide rails 141 is equal to the number of stirring blades 200 and is arranged one-to-one. The guide rails 141 extend along the radial direction of the stirring barrel 100. Specifically, Figure 3 and Figure 4 As shown, a mounting plate 140 is further provided inside the mixing barrel 100. The mounting plate 140 is provided as a circular plate structure and is coaxially inserted inside the mixing barrel 100. The mounting plate 140 is located between the barrel cover 110 and the partition plate 130 during installation. A guide rail 141 is provided on the top surface of the mounting plate 140 and extends in the radial direction of the mounting plate 140. A plurality of guide rails 141 are arranged on the mounting plate 140 in a circumferential direction. The guide block 142 can slide along the guide rail 141 and is movably connected to the central shaft 210. Specifically, as shown in FIG. Figure 4 As shown, a connecting rod 240 is provided at the bottom of the guide block 142, the connecting rod 240 can be telescopic, and is connected to the upper end of the central axis 210 through a universal joint 250; more specifically, a plurality of guide grooves 131 are provided on the partition 130, and are arranged one-to-one corresponding to the guide rail 141, and the connecting rod 240 passes through the guide groove 131 when in use; more specifically, the second end of the second hinged rod 430 is sleeved on the connecting rod 240 when in use.

[0034] Taking the case where there are three stirring blades 200 and they are evenly arranged in the stirring barrel 100 along the circumferential direction as an example, initially, the stirring blades 200 are in the first state, such as Figure 4As shown, the axes of the three central shafts 210 are all arranged parallel to the axis of the mixing barrel 100, and the three central shafts 210 approximately surround and form a triangular prism shape; in the process of switching the mixing fan blade 200 from the first state to the second state, the central disk 410 is driven to rotate under the action of an external force, and the central disk 410 synchronously drives the corresponding second hinged rods 430 to rotate through the three first hinged rods 420, so that the second hinged rods 430 can be axially swung in the direction of the axis close to the central disk 410 with the second end of the corresponding first hinged rod 420 as the axial direction, and the second hinged rod 430 drives the guide block 142 to move along the guide rail 141 and in the direction of the axis close to the mounting plate 140 through the connecting rod 240; when the central disk 410 rotates to a preset angle, the mixing fan blade 200 is in the second state, as shown in FIG. Figure 5 As shown, the axes of the three central axes 210 have a preset angle with the axis of the mixing barrel 100 and intersect at the same point, and the three central axes 210 approximately surround and form a triangular pyramid shape.

[0035] In other embodiments, the adjustment mechanism can also be configured to include a drive cylinder and a guide assembly, and the number of drive cylinders is set to be equal to the number of stirring blades 200, and is arranged one-to-one. Taking one drive cylinder as an example, the drive cylinder is arranged on the mounting plate 140, and the axial direction of the output shaft is arranged parallel to the radial direction of the mounting plate 140, and is fixedly connected to the guide block 142 to drive the corresponding stirring blade 200 to move through the guide block 142.

[0036] It can be understood that the driving cylinder can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0037] In some embodiments, the central shaft 210 and the spiral blade 220 are connected by a mounting rod 230. Specifically, Figure 4 As shown, the central axis 210 and the spiral blades 220 are spaced apart in the radial direction and connected by a mounting rod 230, so that during the stirring process of the raw materials, the raw materials can pass through the gap between the central axis 210 and the spiral blades 220 for mixing, making the movement of the raw materials more chaotic, so as to improve the stirring effect of the raw materials.

[0038] In a further embodiment, Figure 4 As shown, there are two spiral blades 220, which are symmetrically arranged on the central axis 210. Therefore, during the stirring process of the raw materials, the raw materials can not only pass through the gap between the central axis 210 and the spiral blades 220 for mixing, but also during the process of the stirring fan blade 200 rotating one circle, the spiral blades 220 can stir the raw materials twice to improve the stirring efficiency of the raw materials.

[0039] In some embodiments, the transmission assembly is configured to further include a first driving member, and the first driving member is configured to provide a driving force for the rotation of the center disk 410. Specifically, the first driving member is configured to adjust the motor 400, such as Figure 4 As shown, the adjusting motor 400 is fixedly connected to the bottom of the mounting plate 140 by bolts, and the motor shaft of the adjusting motor 400 is arranged downward along the axial direction of the mixing barrel 100, and the axis of the motor shaft coincides with the axis of the mixing barrel 100, and is fixedly connected to the center disk 410 to drive the center disk 410 to rotate.

[0040] In some embodiments, the food production stirring device is configured to further include a second driving member, and the second driving member is configured to provide a driving force for the stirring blade 200 to rotate. Specifically, the second driving member is configured to be a stirring motor 300, such as Figure 3 As shown, there are multiple stirring motors 300, and they are arranged one by one corresponding to the guide blocks 142. Taking one stirring motor 300 as an example, the stirring motor 300 is fixedly connected to the bottom of the guide block 142 by bolts, and the motor shaft of the stirring motor 300 is arranged downward along the axial direction of the stirring barrel 100, and is coaxially inserted in the connecting rod 240 to drive the stirring blades 200 to rotate through the connecting rod 240 and the universal joint 250.

[0043] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
