Description

Technical Field

[0001] This utility model relates to the field of stone paint production technology, specifically a premixing device for stone paint production. Background Technology

[0002] In the field of building decoration materials, real stone paint is widely used in building exterior wall decoration due to its decorative effect that closely resembles natural stone and its good weather resistance. As the construction industry continues to raise the requirements for the performance of decorative materials, the production quality of real stone paint has attracted much attention. Premixing, as a key initial step in the production of real stone paint, directly affects the uniformity, construction performance and final decorative effect of the subsequent coating.

[0003] Currently, some existing premixing devices for stone paint have attempted to implement blade rotation functionality through structural improvements. Their technical solutions typically employ a fixed transmission structure (such as gear meshing or linkage mechanisms) to drive the blades to rotate simultaneously with the stirring shaft's revolution, thereby enhancing the material shearing and mixing effect. The working process is as follows: the stirring shaft drives the blades to revolve and tumble the material, while a fixed transmission component forces the blades to rotate, allowing the aggregate and emulsion components to initially mix in the combined motion of revolution and rotation. However, existing premixing devices with blade rotation functionality still have significant drawbacks: firstly, the blade rotation function cannot be automatically turned on or off according to production needs. When processing low-viscosity raw materials or when high-intensity mixing is not required, forced rotation may lead to excessive shearing of the material, damaging the particle structure; secondly, the amplitude and speed of blade rotation lack an adjustable mechanism, making it difficult to adapt to the mixing requirements of raw materials with different viscosities and proportions, resulting in poor device versatility and an inability to provide a stable premixing foundation for subsequent deep mixing of stone paint. Therefore, we propose a premixing device for stone paint production. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a premixing device for the production of real stone paint, which allows for selective opening of the blade rotation and adjustment of the rotation amplitude, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a premixing device for the production of real stone paint, including a shell, a feed pipe provided on the rear side of the outer arc surface of the shell, a discharge pipe provided on the lower side wall of the shell, and a mixing mechanism;

[0006] Mixing mechanism: It includes a stirring shaft, a mounting shaft, blades, and an adjusting column. The stirring shaft is rotatably connected to the middle of the upper side wall of the outer shell. The mounting shaft is rotatably connected to the mounting hole at the lower end of the stirring shaft. Blades are provided at both ends of the mounting shaft. An adjusting column for driving the rotation of the mounting shaft is provided inside the stirring shaft. An adjustable wave ring is provided at the upper end of the outer shell. The wave ring is installed in conjunction with the upper end of the adjusting column. The selective opening of the blade rotation and the adjustment of the rotation amplitude are realized through the cooperation of the wave ring and the adjusting column. This effectively solves the problems of non-selective blade rotation and non-adjustable amplitude in the prior art, making the premixing of the real stone paint raw materials more uniform and adaptable to different production needs.

[0007] Furthermore, a control switch is provided on the left side of the housing, and the input terminal of the control switch is electrically connected to an external power source for stable control.

[0008] Furthermore, the mixing mechanism also includes a gear, a rack plate, and a sliding hole. The upper side wall of the stirring shaft is provided with a sliding hole. The adjusting column is slidably connected to the inside of the sliding hole. The lower end of the adjusting column is fixedly connected to a rack plate. The gear is fixedly connected to the middle of the outer arc surface of the mounting shaft and located inside the stirring shaft. The gear meshes with the rack plate and can drive the blades to rotate.

[0009] Furthermore, the mixing mechanism also includes a limiting platform and a spring. The upper end of the adjusting column is provided with a limiting platform, and a spring is provided between the lower side of the limiting platform and the upper side of the stirring shaft for resetting the adjusting column.

[0010] Furthermore, the upper side of the outer shell is provided with a protective shell, and the upper side of the protective shell is provided with an electric cylinder. The telescopic end of the electric cylinder penetrates through the upper side wall of the protective shell. A mounting plate is provided at the telescopic end of the electric cylinder. The wave ring is fixedly connected to the lower side of the mounting plate. The input end of the electric cylinder is electrically connected to the output end of the control switch to adjust the position of the wave ring.

[0011] Furthermore, a driven gear is provided on the outer arc surface of the upper end of the stirring shaft, and a main gear is rotatably connected to the upper side of the outer shell through a rotating shaft. The main gear meshes with the driven gear. A motor is installed on the upper side of the protective shell. The output shaft of the motor passes through the upper side wall of the protective shell and is fixedly connected to the center of the upper end face of the rotating shaft. The input end of the motor is electrically connected to the output end of the control switch for stable driving.

[0012] Furthermore, an electric valve is connected in series in the middle of the discharge pipe, and the input end of the electric valve is electrically connected to the output end of the control switch for discharging materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This premixing device for the production of genuine stone paint has the following advantages:

[0014] The premixing device used in the production of genuine stone paint not only achieves large-scale material agitation by driving the blades to revolve through the stirring shaft, but also allows for the selection of whether the blades rotate independently. The cooperation between the wave ring and the adjusting column causes the blades to rotate, forming a compound motion to break up particle agglomeration and make the aggregate, emulsion, additives and other components more uniformly mixed, avoiding stratification or clumping. At the same time, the height of the wave ring can be adjusted by the electric cylinder to change the speed and amplitude of the blade rotation, adapting to the mixing needs of raw materials with different viscosities or ratios. The overall structure is highly efficient and practical, laying a good foundation for the subsequent deep mixing of genuine stone paint. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-8 This embodiment provides a technical solution: a premixing device for producing real stone paint, including a shell 1, a control switch 12 on the left side of the shell 1, the input end of the control switch 12 being electrically connected to an external power source, a feed pipe 3 on the rear side of the outer arc surface of the shell 1, a discharge pipe 4 on the lower side wall of the shell 1, an electric valve 5 connected in series in the middle of the discharge pipe 4, the input end of the electric valve 5 being electrically connected to the output end of the control switch 12, and also includes a mixing mechanism 2;

[0026] Mixing mechanism 2 includes a stirring shaft 21, a mounting shaft 22, blades 23, and an adjusting column 27. The stirring shaft 21 is rotatably connected to the middle of the upper side wall of the outer casing 1. The stirring shaft 21 and the middle of the upper side wall of the outer casing 1 are rotatably connected via a first sealed bearing. The mounting shaft 22 is rotatably connected to the mounting hole at the lower end of the stirring shaft 21 (the mounting shaft 22 and the inner arc surface of the mounting hole are rotatably connected via a second sealed bearing). Blades 23 are provided at both ends of the mounting shaft 22. An adjusting column 27 for driving the mounting shaft 22 to rotate is provided inside the stirring shaft 21. The mixing mechanism 2 also includes a gear 24, a rack 25, and a sliding hole 26. The upper side wall of the stirring shaft 21 has a sliding hole 26, and the adjusting column 27 is slidably connected inside the sliding hole 26. The lower end of the adjusting column 27... A rack plate 25 is fixedly connected to the end of the mixing mechanism 2. A gear 24 is fixedly connected to the middle of the outer arc surface of the mounting shaft 22 and located inside the stirring shaft 21. The gear 24 meshes with the rack plate 25. The mixing mechanism 2 also includes a limiting platform 28 and a spring 29. The upper end of the adjusting column 27 is provided with a limiting platform 28. A spring 29 is provided between the lower side of the limiting platform 28 and the upper side of the stirring shaft 21. The limiting platform 28 is used in conjunction with the wave ring 7. The upper end of the outer shell 1 is provided with an adjustable wave ring 7. The wave ring 7 is installed in conjunction with the upper end of the adjusting column 27. The upper side of the outer shell 1 is provided with a protective shell 13. The upper side of the protective shell 13 is provided with an electric cylinder 11. The telescopic end of the electric cylinder 11 penetrates the upper side wall of the protective shell 13. The telescopic end of the electric cylinder 11 is provided with a mounting plate 6. The wave ring 7 is fixed. Connected to the lower side of the mounting plate 6, the input end of the electric cylinder 11 is electrically connected to the output end of the control switch 12. A driven gear 8 is provided on the outer arc surface of the upper end of the stirring shaft 21. A main gear 9 is rotatably connected to the upper side of the outer casing 1 via a rotating shaft. The main gear 9 meshes with the driven gear 8. A motor 10 is mounted on the upper side of the protective casing 13. The output shaft of the motor 10 passes through the upper side wall of the protective casing 13 and is fixedly connected to the center of the upper end face of the rotating shaft. The input end of the motor 10 is electrically connected to the output end of the control switch 12. When the control switch 12 starts the motor 10, the motor output shaft drives the rotating shaft to rotate, thereby driving the main gear 9 to rotate. The main gear 9 meshes with the driven gear 8, causing the stirring shaft 21 to rotate around the central axis of the outer casing 1. The lower end of the stirring shaft 21 has a mounting shaft 22 and blades 23. The stirring shaft rotates synchronously, initially stirring the stone paint raw materials inside the outer shell 1, achieving large-scale material agitation. After the electric cylinder 11 is started by the control switch 12, its telescopic end drives the mounting plate 6 to move the wave ring 7 downward. The wave-shaped contour of the wave ring 7 contacts the upper end of the limiting platform 28. The limiting platform 28 then drives the adjusting column 27 to reciprocate linearly within the sliding hole 26 according to the undulation of the wave. (The wave ring 7 is circular when viewed from above, and its main view is wave-shaped. The center of the circle in the top view of the wave ring 7 is located on the central axis of the stirring shaft 21. The limiting platform 28 is composed of a circular plate and a convex ball fixed at the upper end of the circular plate. This ensures that when the limiting platform 28 rotates with the stirring shaft 21, the circular plate of the limiting platform 28 always contacts the bottom end of the outer surface of the wave ring 7.)The convex ball of the limiting platform 28 is located inside the wave ring 7. When the adjusting column 27 moves downward, the limiting platform 28 compresses the spring 29. When the limiting platform 28 rotates to the highest point of the wave-shaped profile of the wave ring 7, the spring 29 pushes the adjusting column 27 upward through the limiting platform 28 (ensuring that the limiting platform 28 is always in contact with the wave ring 7). The rack plate 25 at the lower end of the adjusting column 27 moves up and down with the adjusting column 27 and meshes with the gear 24 on the mounting shaft 22, thereby driving the mounting shaft 22 and the blade 23 to rotate. The blade 23 has two kinds of motion: the revolution with the stirring shaft 21 (large-scale material turning) and its own selective rotation (local high-speed shearing of materials). This compound motion can break up the material in the real stone paint raw material. The particle agglomeration ensures a more uniform mixing of aggregates, emulsions, and additives, preventing stratification or clumping. Adjusting the height of the wave ring 7 via the electric cylinder 11 changes the movement amplitude of the adjusting column 27, thereby adjusting the rotation speed and amplitude of the blades 23 to accommodate the mixing needs of different viscosities or ratios of the stone paint raw materials. Pre-mixing is achieved through the combined motion of the stirring shaft 21 and the blades 23, ensuring a preliminary uniform distribution of aggregates, emulsions, and other components, laying the foundation for subsequent deep mixing. The raw materials enter the outer casing 1 through the feed pipe 3. After mixing, the control switch 12 opens the electric valve 5, and the material is discharged from the discharge pipe 4. The pre-mixing of the stone paint is completed through the combined motion of the stirring shaft 21 and the blades 23.

[0027] The working principle of the premixing device for producing real stone paint provided by this utility model is as follows: The control switch 12 starts the motor 10, and the motor output shaft drives the rotating shaft to rotate, which in turn drives the main gear 9 to rotate. The main gear 9 meshes with the driven gear 8, causing the stirring shaft 21 to rotate around the central axis of the outer shell 1. The mounting shaft 22 and blades 23 at the lower end of the stirring shaft 21 rotate synchronously with the stirring shaft, performing preliminary stirring of the real stone paint raw materials in the outer shell 1, realizing a large-scale material agitation. After the electric cylinder 11 is started by the control switch 12, its telescopic end drives the mounting plate 6 to move the wave ring 7 downward. The wave-shaped contour of the wave ring 7 contacts the upper end of the limiting platform 28. The limiting platform 28 then drives the adjusting column 27 to make reciprocating linear motion in the sliding hole 26 with the undulation of the wave. (When the adjusting column 27 moves downward, the limiting platform 28 compresses the spring 29. When the limiting platform 28 rotates to the highest point of the wave-shaped contour of the wave ring 7, the spring 29 pushes the adjusting column 27 upward through the limiting platform 28, ensuring that the limiting platform 28 is always in contact with the wave ring.) (7 contact), the rack plate 25 at the lower end of the adjusting column 27 moves up and down with the adjusting column 27 and meshes with the gear 24 on the mounting shaft 22, thereby driving the mounting shaft 22 and the blade 23 to rotate. The blade 23 has two motions: it revolves with the stirring shaft 21 (large-scale turning of materials) and it can selectively rotate on its own (local high-speed shearing of materials). This compound motion can break up the particle agglomeration in the real stone paint raw materials, so that the aggregate, emulsion, additives and other components are mixed more evenly, avoiding the occurrence of stratification or agglomeration. By adjusting the height of the wave ring 7 by the electric cylinder 11, the movement range of the adjusting column 27 can be changed, thereby adjusting the speed and amplitude of the rotation of the blade 23 to adapt to the mixing needs of real stone paint raw materials with different viscosities or ratios. The premixing is completed by the compound motion of the stirring shaft 21 and the blade 23, so that the aggregate, emulsion and other components are initially evenly distributed, laying the foundation for subsequent deep mixing. The raw materials enter the outer shell 1 through the feed pipe 3. After the mixing is completed, the control switch 12 opens the electric valve 5, and the material is discharged from the discharge pipe 4.

[0028] It is worth noting that the electric valve 5 disclosed in the above embodiments can be a conventional electric discharge valve, the motor 10 can be an M2AA series, the electric cylinder 11 can be a SEA802 model, and the control switch 12 is equipped with control buttons that correspond one-to-one with the electric valve 5, the motor 10 and the electric cylinder 11 and are used for the controller switch.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
