The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0017] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0018] like Figures 1 to 3As shown, the present invention provides a paint mixing mixer, comprising: The main frame 1 has a receiving area 10 for accommodating and positioning the mixing container 6, and the top of the main frame 1 has an opening; A positioning mechanism, disposed on the main frame 1, is used to constrain the stirring position of the mixing container 6 within the accommodating area 10; A stirring mechanism, which includes a stirring element 31 and a stirring drive assembly 32 for driving the stirring element 31 to perform a stirring action; An axial displacement mechanism is disposed on the main frame 1, and the stirring mechanism is provided thereon; the axial displacement mechanism is used to drive the stirring mechanism to move along the direction of the accommodating area 10. The protective cover 5 is fixed to the axial displacement mechanism and moves synchronously with it, and circumferentially surrounds the stirring element 31; When the axial displacement mechanism drives the stirring element 31 to move downward through the opening and extend into the interior of the mixing container 6, the lower end of the protective cover 5 moves synchronously to cover the top opening of the mixing container 6.

[0019] In this embodiment, before stirring, the paint to be mixed is poured into the mixing container 6, and then the mixing container 6 is placed in the receiving area 10. Next, the positioning mechanism is activated, which constrains the stirring position of the mixing container 6 within the receiving area 10, ensuring that the mixing container 6 remains stable during stirring. Then, the axial displacement mechanism drives the stirring mechanism to descend, causing the stirring element 31 to move downwards from the opening and extend into the interior of the mixing container 6. Then, the stirring drive assembly 32 drives the stirring element 31 to perform a stirring action, achieving mixing of the paint in the mixing container 6. Simultaneously, as the stirring element 31 extends into the mixing container 6, the lower end of the protective cover 5 moves synchronously to cover the top opening of the mixing container 6. This seals the opening area of ​​the mixing container 6 with the protective cover 5, preventing paint from splashing out during stirring. The axial displacement mechanism synchronously moves the protective cover 5 downwards, achieving active isolation and protection of the mixing container 6, making operation simpler and more convenient.

[0020] In a preferred embodiment, the positioning mechanism includes: The fixed clamping unit 21 is fixedly disposed on one side of the receiving area 10; The movable clamping unit 22 is disposed opposite to the fixed clamping unit 21 on the opposite side of the receiving area 10; The positioning drive component 23 is fixed on the main frame 1; The positioning drive component 23 is used to drive the movable clamping unit 22 to move back and forth along the clamping direction, so that the movable clamping unit 22 selectively moves closer to or away from the fixed clamping unit 21, thereby applying or releasing radial constraint force to the mixing container 6 placed in the accommodating area 10.

[0021] In this embodiment, the positioning drive component 23 drives the movable clamping unit 22 to selectively approach or move away from the fixed clamping unit 21, thereby clamping or releasing the mixing container 6, which is simple in structure; the fixed clamping unit 21 and the movable clamping unit 22 apply radial constraint force to the mixing container 6, making the clamping more stable and firm.

[0022] Specifically, the positioning drive component 23 is a linear cylinder, and the piston rod end of the linear cylinder is connected to the movable clamping unit 22. Driving the movable clamping unit 22 with the linear cylinder allows for linear movement, resulting in high control precision.

[0023] It is understood that the positioning drive component 23 can also be other drive components, such as cylinder screw mechanism or motor.

[0024] In a preferred embodiment, both the fixed clamping unit 21 and the movable clamping unit 22 have a buffer layer 24 on their working surfaces. By providing the buffer layer 24, excessive noise is avoided during the clamping process, while also protecting the mixing container 6.

[0025] In a preferred embodiment, the axial displacement mechanism includes an axial guide post 41, a movable platform 42 that slides with the axial guide post 41, a fixed platform 43 fixed to the top of the axial guide post 41, and an axial cylinder 44 disposed on the fixed platform 43.

The stirring drive assembly 32 and the protective cover 5 are both mounted on the movable platform 42.

[0026] In this embodiment, the movable platform 42 is driven by the axial cylinder 44 to move up and down along the axial guide post 41, thereby realizing the lifting and lowering movement of the stirring mechanism. The protective cover 5 is installed on the movable platform 42 and moves up and down synchronously with the stirring mechanism. The structure is compact and the operation is convenient. Specifically, the movable platform 42 is provided with an axial guide sleeve, which slides in conjunction with the axial guide post 41.

[0027] In a preferred embodiment, the axial guide post 41 is provided with a limiting adjustment structure 45, which is used to constrain the position of the movable platform 42 on the axial guide post 41.

[0028] In this embodiment, by setting a limiting adjustment structure 45, the depth of the stirring element 31 extending into the mixing container 6 can be adjusted to adapt to different stirring requirements. Specifically, the limiting adjustment structure 45 is preferably a limiting sleeve, which is provided with an adjusting screw. When the limiting sleeve moves to a preset position, the limiting sleeve can be fixed by tightening the adjusting screw.

[0029] In a preferred embodiment, the stirring element 31 includes an axially arranged stirring shaft 311, the connecting end of the stirring shaft 311 is connected to the output end of the stirring drive assembly 32, and the stirring end of the stirring shaft 311 is equipped with multiple sets of vertically arranged blade assemblies 312.

[0030] In this embodiment, the stirring drive component 32 drives the stirring shaft 311 to select, thereby enabling the blade assembly 312 to stir the material. Compared with the stirring blades 3122 of the traditional unit, this embodiment uses a design in which multiple sets of blade assemblies 312 are arranged in a vertical distribution, which not only improves the uniformity of stirring, but also greatly improves the stirring efficiency.

[0031] In a preferred embodiment, each set of blade assemblies 312 includes a sleeve 3121 and a plurality of stirring blades 3122 circumferentially disposed outside the sleeve 3121. The sleeve 3121 is connected to the stirring shaft 311 by a detachable structure.

[0032] In this embodiment, the paint is stirred by multiple stirring blades 3122, which helps to improve the mixing effect. A detachable structure allows for a detachable connection between the sleeve 3121 and the stirring shaft 311, facilitating the disassembly, cleaning, or replacement of the blade assembly 312. Specifically, the sleeve 3121 has an axially through-hole, which is press-fitted with the stirring shaft 311. This press-fit ensures the stability of the blade assembly 312 on the stirring shaft 311, preventing loosening during high-speed rotation.

[0033] In a preferred embodiment, the bottom of the movable platform 42 is provided with a bearing seat 46, the output end of the stirring drive assembly 32 passes through the movable platform 42 and is inserted into the bearing seat 46, the bearing seat 46 is provided with a bearing assembly 47, the upper end of the stirring element 31 passes through the bearing assembly 47 and is connected to the output end of the stirring drive assembly 32 through a coupling 33.

[0034] In this embodiment, the stirring element 31 is connected to the output end of the stirring drive assembly 32 via a coupling 33, thereby transmitting power from the stirring drive assembly 32 to the stirring element 31 and enabling the stirring element 31 to rotate. The stability of the stirring element 31 during rotation is ensured by the bearing housing 46 and the bearing assembly 47, while the coupling 33 is used to compensate for possible installation deviations and transmit torque.

[0035] In a preferred embodiment, the accommodating area 10 is provided with a support base 11 and a positioning structure 12. The support base 11 is provided with a pulley 110. The main frame 1 is provided with an opening for the support base 11 to slide into or out of the accommodating area 10. The upper surface of the support base 11 is provided with a plurality of limiting blocks 111. The plurality of limiting blocks 111 surround to form a limiting area for constraining the mixing container 6. The positioning structure 12 is used to position the support base 11 in the stirring position of the accommodating area 10 so that the stirring element 31 is inserted into the center position of the mixing container 6.

[0036] In this embodiment, the support base 11 is first slid out of the receiving area 10 so that the mixing container 6 can be placed on the support base 11. Then, the support base 11 is pushed into the receiving area 10. The positioning structure 12 restricts the displacement of the support base 11 in the receiving area 10, ensuring that the support base 11 is positioned at the stirring position in the receiving area 10. This allows the stirring element 31 to be axially inserted into the center of the mixing container 6, which helps to improve the stirring effect. The limiting block 111 on the support base 11 can prevent the mixing container 6 from shifting randomly on the support base 11. At the same time, during the stirring process, the limiting block 111 also serves to fix the mixing container 6.
