Description

Technical Field

[0001] This utility model belongs to the field of stirring blade technology, and specifically relates to a stirring blade for a stirring device. Background Technology

[0002] A mixer is a machine that uses a bladed shaft to rotate within a mixing container or tank, mixing various raw materials to create a mixture or a suitable consistency. There are many types of mixers, including forced-action mixers, single-shaft mixers, twin-shaft mixers, and so on. The internal mixing components of a mixer include the mixing rod and the mixing blades, with the blades playing a crucial role.

[0003] Patent application number 2020800189784 discloses a stirring blade assembly and a stirring tank. The stirring blade assembly is disposed in a tank storing liquid and is used to stir the liquid. The stirring blade assembly includes: a first stirring blade disposed at the bottom of the tank and supported to rotate about a rotation axis parallel to the vertical direction, causing the liquid to flow upward along the side wall of the tank in a direction away from the rotation axis during rotation; and a second stirring blade disposed above the first stirring blade. The second stirring blade is supported to rotate about the rotation axis, causing the liquid to flow downward in the vertical direction away from the rotation axis during rotation and without obstructing the first liquid flow.

[0004] The above-mentioned solution improves the mixing effect by using special mixing blades. However, many current mixers are mixing container structures with a small neck diameter and a large body diameter. To facilitate maintenance of the mixing rod and blades, shorter blades are usually used to allow easy access from the neck. However, this results in a smaller mixing range and a poorer mixing effect. Utility Model Content

[0005] To solve the above problems, this utility model provides a stirring blade for a stirring device, including a stirring rod, a connecting seat connected to the bottom of the stirring rod, and at least two stirring blades provided on the side of the connecting seat. The stirring blades are folded and switch from a folded state to an unfolded state after the stirring rod is rotated.

[0006] Preferably, the stirring blade includes a first blade segment and a second blade segment, and a hinge connects the first blade segment and the second blade segment, allowing the first blade segment and the second blade segment to be folded horizontally via the hinge.

[0007] Preferably, the side of the connecting seat is provided with a protruding hinge portion, and a flip plate is hinged to the hinge portion. The flip plate is vertically flipped around the hinge portion, and a stirring blade is connected to the flip plate. The stirring blade is folded vertically through the flip plate.

[0008] Preferably, the flip plate includes a connecting section and a hinge section, the connecting section and the hinge section are bent, the hinge section is hinged to the hinge part, the connecting section is perpendicularly connected to the stirring blade, and the width of the stirring blade near the connecting seat is greater than the width of the stirring blade away from the connecting seat.

[0009] Preferably, the connecting seat has a threaded groove in the middle, and the threaded groove is threadedly connected to the stirring rod.

[0010] The advantages of this utility model are:

[0011] 1. This solution designs the stirring blades as a folding structure, allowing them to be horizontally folded when not rotating, significantly reducing their overall size. This enables the stirring rod and blade assembly to fit smoothly into the narrow opening of the container, facilitating the installation, disassembly, and transportation of the equipment. It is suitable for stirring containers with limited diameter.

[0012] 2. In this design, during the rotation of the stirring rod, the centrifugal force generated by the rotation causes the second blade segment to automatically switch from a folded state to an unfolded state, realizing the dynamic conversion of the stirring blade from a small diameter to a large diameter. This increases the coverage area and stirring radius of the stirring blade, thereby significantly improving stirring efficiency and uniformity.

[0013] 3. This solution adopts a vertically flipping mixing blade design, which allows the mixing blades to hang naturally in the vertical direction when not in operation, greatly reducing the projected size of the blades in the axial direction. This makes it easier for the entire mixing assembly to pass through narrower container necks, improving the equipment's adaptability to container sizes. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Simultaneously, when an component is referred to as "fixed to" or "equipped on" another component, it can be directly on the other component or may have an intervening component present. When an component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present. When an component is referred to as "fixedly connected to" another component, it can be a common fixed connection method such as welding, bolting, or gluing. In short, those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1, such as Figure 1-2 As shown, a stirring blade for a stirring device includes a stirring rod, a connecting seat 2 connected to the bottom of the stirring rod, and two stirring blades 3 disposed on the side of the connecting seat 2. The stirring blades 3 are folded, and the stirring blades 3 switch from a folded state to an unfolded state after the stirring rod rotates. Specifically, the stirring blades 3 include a first blade segment 4 and a second blade segment 5. One end of the first blade segment 4 is connected to the connecting seat 2, and a hinge 6 connects the other end of the first blade segment 4 and the second blade segment 5. The first blade segment 4 and the second blade segment 5 are folded horizontally together by the hinge 6.

[0024] Combination Figure 2When it is necessary to place the stirring rod and stirring blade 3 into the mixing container, the first blade segment 4 and the second blade segment 5 are folded. At this time, the first blade segment 4 and the second blade segment 5 are in a horizontally folded state, and the maximum distance between them is reduced, which makes it easier to enter from the neck of the mixing container. When the stirring blade 3 reaches the bottom of the mixing container, the stirring rod drives the bottom stirring blade 3 to rotate to stir. The first blade segment 4 is in a rotating state, and under the action of centrifugal force, combined with Figure 1 The second blade segment 5 also switches from a folded state to an unfolded state, and the maximum distance between the first blade segment 4 and the second blade segment 5 increases, and its stirring diameter also increases accordingly.

[0025] By designing the stirring blade 3 as a foldable structure, it can be horizontally folded when not rotating, significantly reducing its overall size. This allows the stirring rod and blade assembly to easily fit into narrow container openings, facilitating installation, disassembly, and transportation, making it suitable for stirring containers with limited diameters. This structure achieves automatic deployment and retraction of the stirring blade 3 without the need for external power or complex control mechanisms, relying on its own design and physical and mechanical properties to complete the state switching, thus reducing the failure rate.

[0026] Example 2, as Figure 3-5 As shown, a stirring blade for a stirring device includes a stirring rod. A connecting seat 2 is connected to the bottom of the stirring rod, and a threaded groove 11 is provided in the middle of the connecting seat 2. The threaded groove 11 is threadedly connected to the stirring rod 1. This threaded connection eliminates the need for welding or other fasteners, allowing users to quickly install or remove the stirring rod 1 as needed. To ensure that the stirring rod 1 does not loosen due to the direction of rotation during rotation, the thread direction of the threaded groove 11 should be opposite to the rotation direction of the stirring rod 1. This ensures that the connection structure tightens under the rotational torque during stirring, guaranteeing the reliability and safety of the connection.

[0027] The connecting seat 2 has three stirring blades 3 on its side. The stirring blades 3 are folded, and after the stirring rod rotates, they switch from a folded state to an unfolded state. Specifically, the connecting seat 2 has a protruding hinge part 7 on its side. The hinge part 7 consists of two protruding plate-like structures, with a hinge groove formed between the two plates. A flip plate 8 is hinged in the hinge groove, and the flip plate 8 flips vertically around the hinge part 7. The stirring blades 3 are connected to the flip plate 8, and the stirring blades 3 are folded vertically by the flip plate 8.

[0028] Combination Figure 4 In the folded state, the three stirring blades 3 fold downwards, allowing them to quickly pass through the neck of the mixing container. Once the stirring blades 3 reach the bottom of the mixing container, the stirring rod drives the bottom stirring blades 3 to rotate, thus stirring the mixture under centrifugal force. Figure 3The three stirring blades 3 flip upwards, switching from a folded state to an unfolded state. This increases the stirring diameter. Compared to Example 1, by adopting a vertically flipping stirring blade design, the stirring blades 3 can hang naturally in the vertical direction when not in operation, significantly reducing the projected size of the blades in the axial direction. This makes it easier for the entire stirring assembly to pass through narrower container necks, improving the equipment's adaptability to container sizes. The stirring blades 3 achieve vertical flipping through the flipping plate 8 hinged to the connecting seat 2. During rotation, under the action of centrifugal force, they can quickly flip from a drooping state to a horizontally unfolded state, giving the stirring blades 3 a larger unfolding angle and a larger stirring diameter when in operation, thus significantly enhancing the stirring effect and coverage area.

[0029] The tilting plate 8 includes a connecting section 9 and a hinged section 10. Both sections are bent, and the hinged section 10 is hinged to the hinged part 7. The connecting section 9 is perpendicularly connected to the stirring blade 3. This perpendicular connection ensures that the stirring blade 3 remains stably positioned at a preset angle after tilting and unfolding, maintaining its working posture, improving stirring efficiency and stability, and preventing eccentricity or imbalance caused by improper unfolding angle. The width of the stirring blade 3 near the connecting seat 2 is greater than the width of the stirring blade 3 away from the connecting seat 2. This gradually changing width reduces fluid resistance and energy consumption during rotation, while generating stronger shearing and disturbance effects in the area away from the axis, contributing to more thorough stirring and mixing. Furthermore, because the distal end of the stirring blade 3 is narrower, its overall profile is smaller in the folded state, facilitating passage through narrow container inlets and reducing interference between adjacent blades, thus improving the compactness and applicability of the equipment.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
