In the process of producing and processing paint, it is necessary to thoroughly mix and stir various raw materials used in paint production. A mixing and stirring device for paint production is a device used to mix and stir various raw materials used in paint production, and it is widely used in the field of paint production.

[0003] A mixing and stirring device for paint production in related technology includes a vessel body with a working chamber inside. A stirring mechanism is installed inside the working chamber, and a power mechanism is located at the top of the stirring mechanism, installed at the top center of the vessel body. A feeding pipe assembly and a discharging pipe assembly are respectively connected to the top and bottom of the working chamber. In use, the existing mixing and stirring device for paint production starts by activating the power mechanism, causing the stirring mechanism to rotate within the working chamber of the vessel body. Simultaneously, multiple groups of paint are added to the working chamber of the vessel body in a specified quantity and order through the feeding pipe assembly. This achieves mixing and stirring of the multiple groups of raw materials within the working chamber. After the multiple groups of raw materials are fully mixed and stirred, the fully mixed raw materials can be discharged from the vessel body through the discharging pipe assembly.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: the stirring mechanism in the related technologies is usually a stirring blade with a fixed angle. The disturbance effect of such a fixed-angle stirring blade on the material is relatively fixed during the rotation of a fixed speed, which is not convenient for adjusting the stirring angle according to the different properties (such as viscosity) of the material, and therefore needs to be improved. Summary of the Invention

[0005] In order to achieve the adjustment of the stirring angle, this application provides a coating mixing and stirring device.

[0006] A coating mixing and stirring device includes a vessel body, an internal stirring mechanism, a power mechanism for driving the stirring mechanism to rotate, a feeding pipe at the top of the vessel body, a discharge pipe at the bottom of the vessel body, the stirring mechanism including a stirring sleeve and stirring blades, the power mechanism being connected to the stirring sleeve, the stirring blades being rotatably connected to the stirring sleeve, and the stirring sleeve being equipped with an adjustment component for adjusting the tilt angle of the stirring blades.

[0025] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0026] This application mainly adopts a stirring mechanism with adjustable stirring blade tilt angle, which achieves the effect of adjusting the stirring angle according to different material properties. The following is a further detailed description of this application. Example

[0027] The paint mixing and stirring device provided in this application includes a vessel body 1, a stirring mechanism 11, a power mechanism 12, a feeding pipe 13, and a discharge pipe 14. The power mechanism 12 is connected to the stirring mechanism 11 and drives the stirring mechanism 11 to rotate inside the vessel body 1. The feeding pipe 13 is located at the top of the vessel body 1 and is used to add paint raw materials. The discharge pipe 14 is located at the bottom of the vessel body 1 and is used to discharge the mixed paint. This arrangement enables the device to perform a series of operations, including adding paint raw materials, mixing and stirring, and discharging, meeting the basic requirements of paint production.

[0028] Specifically, the stirring mechanism 11 includes a stirring sleeve 111 and stirring blades 112. The stirring sleeve 111, as an important component of the stirring mechanism 11, is connected to a power mechanism 12, which can be a motor or other equipment. The output shaft of the motor is connected to the stirring sleeve 111, and the motor rotates, driving the stirring sleeve 111 to rotate. The stirring sleeve 111 is typically made of metal, possessing a certain strength and rigidity to ensure it does not deform during rotation. Its shape is generally cylindrical with a smooth surface to reduce friction with the material. The stirring blades 112 are rotatably connected to the stirring sleeve 111, and the stirring sleeve 111 is equipped with an adjustment component 3 for adjusting the tilt angle of the stirring blades 112. The adjustment component 3 is a significant innovation of this device; it can adjust the tilt angle of the stirring blades 112 according to different materials, such as coatings with varying viscosity, thereby changing the disturbance effect of the stirring blades 112 on the material and improving the stirring effect.

[0029] Reference Figure 2 The stirring blade 112 includes a mounting sleeve 113 and blades 2. The mounting sleeve 113 is fixedly connected to the stirring sleeve 111, for example, by welding. The mounting sleeve 113 is generally made of metal and is usually a round tube that fits the stirring sleeve 111, thus ensuring installation stability. Blades 2 are rotatably connected to the mounting sleeve 113, and the adjusting component 3 is connected to blades 2 and used to adjust the tilt angle of blades 2. During rotation, the change in the tilt angle of blades 2 can cause the material to flow in different directions and intensities within the vessel body 1, enhancing the uniformity of stirring.

[0030] The blade 2 includes an inner blade 21 and an outer blade 22. The inner blade 21 is rotatably connected to the side of the mounting sleeve 113 near the center of the vessel body 1, and the outer blade 22 is rotatably connected to the side of the mounting sleeve 113 away from the center of the vessel body 1. This arrangement of inner / outer blades allows for better flow of materials between the inner and outer layers, thus providing a good stirring effect for materials at different locations within the vessel body 1.

[0031] Reference Figure 1 and Figure 3The adjusting assembly 3 includes an adjusting shaft 31 and an adjusting drive component 32 for driving the adjusting shaft 31 to rotate. The adjusting shaft 31 is rotatably connected inside the mounting sleeve 113 and is coaxially arranged. The adjusting shaft 31 is generally a metal shaft with high precision and strength to ensure accurate power transmission during rotation. The adjusting shaft 31 is also connected to a coaxial inner drive gear 33, which is fixedly connected to the inner leaf 21 via an inner rocker arm 34. When the adjusting shaft 31 rotates, it drives the inner drive gear 33 to rotate, thereby changing the inclination angle of the inner leaf 21 via the inner rocker arm 34. A coaxial outer drive gear 35 is also rotatably arranged inside the mounting sleeve 113. A steering gear 37 meshes between the outer drive gear 35 and the inner drive gear 33. The steering gear 37 is rotatably connected to the mounting sleeve 113, and the outer drive gear 35 is fixedly connected to the outer leaf 22 via an outer rocker arm 36. The function of steering gear 37 is to change the rotation direction of inner drive gear 33, so that the rotation direction of outer drive gear 35 is opposite to that of inner drive gear 33, thereby realizing the tilt angle adjustment of inner blade 21 and outer blade 22 in different directions.

[0032] Reference Figure 4 The mounting sleeve 113 is provided with swing holes 38 for the inner swing rod 34 and the outer swing rod 36 to pass through and swing. The size and shape of the swing holes 38 are designed according to the swing range and dimensions of the inner swing rod 34 and the outer swing rod 36 to ensure that the inner swing rod 34 and the outer swing rod 36 can swing freely within the required range. Both the inner swing rod 34 and the outer swing rod 36 are provided with sliding plates 39 for sealing the corresponding swing holes 38. The sliding plates 39 can prevent materials from entering the interior of the mounting sleeve 113 and affecting the normal operation of the adjusting component 3. The sliding plates 39 are generally made of rubber or other materials with a certain degree of elasticity, and their shape is adapted to the swing holes 38, so that they can fit tightly on the swing holes 38 and play a good sealing role.

[0033] Reference Figure 1 The adjustment drive component 32 includes an adjustment motor 321, an adjustment rod 322, a main adjustment gear 323, and a secondary adjustment gear 324. The adjustment rod 322 is rotatably connected inside the stirring sleeve 111 and coaxially arranged. The adjustment motor 321 is connected to the stirring sleeve 111 and is used to drive the adjustment rod 322 to rotate. The adjustment motor 321 can rotate in both directions as needed to increase or decrease the tilt angle of the stirring blade 112. The main adjustment gear 323 is fixedly connected to the adjustment rod 322 and coaxially arranged. The secondary adjustment gear 324 is fixedly connected to one end of the adjustment shaft 31 that extends into the stirring sleeve 111, and the secondary adjustment gear 324 meshes with the main adjustment gear 323. When the adjustment motor 321 drives the adjustment rod 322 to rotate, the main adjustment gear 323 rotates accordingly. Through its meshing with the secondary adjustment gear 324, it drives the adjustment shaft 31 to rotate, thereby adjusting the tilt angle of the stirring blade 112.

[0034] Reference Figure 3A sealing assembly 4 is provided between the adjusting shaft 31 and the stirring sleeve 111. The sealing assembly 4 includes an annular skeleton 41 and a sealing ring 42. The skeleton 41 is fixedly connected to the inner wall of the stirring sleeve 111. The skeleton 41 is generally made of metal and has a certain supporting function. The sealing ring 42 is sleeved on the outside of the adjusting shaft 31 and fixedly connected to the skeleton 41. The sealing ring 42 is usually made of a material with good sealing performance, such as rubber. Its function is to prevent material from leaking into the stirring sleeve 111 and to prevent external dust and other impurities from entering, ensuring the normal rotation of the adjusting shaft 31. An elastic fastening ring 43 is sleeved on the outside of the sealing ring 42. In this embodiment, the elastic fastening ring 43 is a spring ring. The elastic fastening ring 43 can enhance the tightness between the sealing ring 42 and the adjusting shaft 31 and improve the sealing effect. An installation ring groove 44 is provided on the outside of the sealing ring 42 for the elastic fastening ring 43 to be inserted. The installation ring groove 44 allows the elastic fastening ring 43 to be accurately installed on the sealing ring 42, ensuring its installation stability.

[0035] The implementation principle of this embodiment is as follows: The paint mixing and stirring device drives the stirring sleeve 111 to rotate through the power mechanism 12, thereby causing the stirring blades 112 to stir the paint raw materials in the vessel 1. During the stirring process, according to the properties of the material, the regulating motor 321 is started, which drives the regulating rod 322 to rotate. Through the transmission of the main regulating gear 323 and the secondary regulating gear 324, the regulating shaft 31 rotates, and then the tilt angle of the inner blade 21 and the outer blade 22 is adjusted through components such as the inner driving gear 33, the outer driving gear 35, the inner swing rod 34, and the outer swing rod 36, thereby changing the disturbance effect of the stirring blades 112 on the material and achieving a better stirring effect. At the same time, the setting of the sliding plate 39 and the sealing component 4 ensures the sealing of the device, prevents material leakage and impurities from entering, and improves the reliability and service life of the device. Compared with the traditional stirring device with fixed-angle stirring blades 112, this device can flexibly adjust the tilt angle of the stirring blades 112 according to different materials, which greatly improves the adaptability and effect of stirring, meets the diverse needs of paint production, and is an important improvement of the prior art.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
