Description

Technical Field

[0001] This utility model relates to the technical field of external wall water-coated sand feeding device, and in particular to an automatic production feeding device for external wall water-coated sand. Background Technology

[0002] In the production of water-based sand-textured exterior wall coatings, the precise metering and automated dispensing of raw materials have a significant impact on the uniformity, color effect, and batch stability of the final coating. To achieve accurate and efficient proportioning and dispensing of materials such as base paint, colored sand, and additives, a dedicated automated production and dispensing device is typically required. This device usually includes auxiliary functional modules such as metering and weighing, conveying pipelines, valve control, and dust control. Especially in the dispensing of high-viscosity materials or colored sand, precise control of the added material size directly affects production efficiency. Therefore, developing an integrated, precise, and easy-to-operate automated production and dispensing device for water-based sand-textured coatings has become an important direction for process upgrading.

[0003] In existing technologies, the feeding devices used in the automated production of water-coated sand generally include a metering and weighing system, a material conveying mechanism, and an auxiliary screening structure. Structurally, the device includes a vibrating screen assembly for screening the particle size of the colored sand, fixed using flanges, clamps, or other methods. It is also equipped with a vibrating motor or exciter to separate qualified particles from the mixture, preventing coarse materials from contaminating the finished product. In practical use, the screen assembly is usually integrated with the vibrating frame, requiring the entire protective cover to be disassembled for replacement or cleaning. Furthermore, the screen body and fixing device are often locked, making replacement inconvenient and cumbersome.

[0004] However, existing automatic production and feeding devices for water-coated sand in exterior walls still have certain problems in practical applications. On the one hand, different materials require different sizes, and the screens in traditional structures cannot be quickly disassembled and replaced, affecting production accuracy. On the other hand, the inner wall of the mixing tank cannot be completely mixed. These problems reduce the operating efficiency and system convenience of the automatic production and feeding devices for water-coated sand in exterior walls, necessitating optimization in structural design to improve the overall performance of the tool in screen replacement. Therefore, this automatic production and feeding device for water-coated sand in exterior walls is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic production and feeding device for water-coated sand on exterior walls, which aims to improve the problem of the inability to quickly and conveniently replace screens in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic production and feeding device for water-coated sand on exterior walls, including a mixing tank, characterized in that: a quick-change component is fixedly provided in the mixing tank, a mixing component is provided inside the mixing tank, a discharge component is provided on the outer wall of the mixing tank, and a screen is provided on the top of the mixing tank;

[0007] The quick-change assembly includes a connecting column, the bottom of which is fixedly connected to the top of the mixing tank. A groove is formed inside the connecting column. A connecting rod is slidably connected inside the connecting column. A locking block is fixedly connected to one end of the connecting rod. A spring is sleeved on the outer wall of the connecting column. One end of the spring is fixedly connected to one end of the locking block, and the other end of the spring is fixedly connected inside the connecting column.

[0011] The stirring assembly includes a fixed column, the top of which is fixedly connected to the inside of the stirring tank, and a driving column is slidably connected to the inner wall of the fixed column.

[0012] As a further description of the above technical solution:

[0013] A second driving column is fixedly connected to the outer wall of the first driving column, and a rotating ball is fixedly connected to one end of the second driving column.

[0014] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the connecting rod is first pulled, and the connecting rod compresses the spring, causing the locking block to move away from the fixed block, thereby canceling the fixation of the fixed block, removing the screen, and taking out the replacement screen, which slides into the outer shell. The locking block has an inclined structure. When the fixed block slides in, the compression locking block fixes the screen under the spring rebound, achieving the effect of quick screen replacement. This solves the problem that the automatic production and feeding device for water-coated sand on the exterior wall cannot quickly replace the screen during operation, and improves the convenience of the excitation and demagnetization tool.

[0024] 2. In this utility model, the motor is started, and the motor drives the rotating column to rotate. The rotating column drives the rotating plate one and the grab plate two to rotate. Under the action of the rotating ball, the rotational force brought by the motor is converted into the cyclic up and down movement of the column one, achieving the effect of stirring and scraping the wall at the same time during operation. This solves the problem that the automatic production and feeding device for water-coated sand on the outer wall cannot stir and scrape the wall at the same time during operation, and improves the accuracy of the excitation and demagnetization tool.

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.

[0034] Reference Figures 1-4 This utility model provides an embodiment of an automatic production and feeding device for water-coated sand on exterior walls, including a mixing tank 1 for mixing water-coated sand raw materials, providing a corrosion-resistant working chamber to meet the needs of mass production. The mixing tank 1 is fixedly equipped with a quick-change component to quickly replace the screen 2 to adapt to better working needs. The mixing tank 1 is equipped with a mixing component inside to uniformly mix and scrape the wall for accurate and rapid production. The outer wall of the mixing tank 1 is equipped with a discharge component, and the top of the mixing tank 1 is equipped with a screen 2 to ensure the uniformity of the sand and improve the coating quality. The quick-change design adapts to different formula requirements.

[0035] The quick-change assembly includes a connecting column 5, which provides a mounting base and guide structure for the screen 2, and withstands the impact load of the raw materials. The bottom of the connecting column 5 is fixedly connected to the top of the mixing tank 1. A groove 6 is provided inside the connecting column 5 to guide the linear movement of the locking block 8, limit the operating stroke, and prevent overload damage to the mechanism. A connecting rod 3 is slidably connected inside the connecting column 5 to transmit operating force and drive the locking block 8 to quickly unlock the screen 2. One end of the connecting rod 3 is fixedly connected to the locking block 8, which is used to embed into the groove of the fixing block 9 to form a mechanical interlock and withstand vibration and impact. A spring 7 is sleeved on the outer wall of the connecting column 5 to provide elastic restoring force. After the connecting rod 3 is released, the screen 2 is automatically locked. One end of the spring 7 is fixedly connected to one end of the locking block 8, and the other end of the spring 7 is fixedly connected to the inside of the connecting column 5. The fixed connection includes a housing 4, which encapsulates the quick-change mechanism to prevent sand intrusion and extend the service life of the components. The outer wall of the screen 2 slides inside the housing 4. A fixing block 9 is fixedly connected to the outer wall of the screen 2 to integrate a locking interface and ensure precise positioning of the screen 2. A groove 10 is provided inside the fixing block 9 to form a locking position with the locking block 8, constraining lateral displacement and ensuring connection strength. The outer wall of the locking block 8 slides inside the groove 10, and the fixing block 9 slides inside the connecting column 5. The discharge component includes an extension column 21 to extend the discharge height to adapt to different filling equipment interfaces. The bottom end of the extension column 21 is fixedly connected to the outer wall of the mixing tank 1, and the top end of the extension column 21 is fixedly connected to an inlet 22 to receive mixed raw materials. The conical design achieves residue-free conveying and reduces raw material waste.

[0036] Reference Figures 5-6The mixing assembly includes a fixed column 11, which provides a rigid support foundation to withstand the working load of the mixing mechanism and ensure the stability of the equipment under high-speed mixing conditions. The top of the fixed column 11 is fixedly connected to the inside of the mixing tank 1. A driving column 12 is slidably connected to the inner wall of the fixed column 11, which is used to perform up-and-down cyclic rotation under the drive of the rotating ball 19 to achieve three-dimensional mixing and enhance the uniformity of raw material mixing. A driving column 20 is fixedly connected to the outer wall of the driving column 12, which is used to transmit the compound motion force, convert the rotational torque into up-and-down cyclic rotation power, and expand the mixing range. A rotating ball 19 is fixedly connected to one end of the driving column 20, which is used to convert the rotational motion of the rotating plate 18 into up-and-down cyclic rotation. The ball joint structure eliminates motion interference and improves transmission efficiency. The inner wall of the mixing tank 1 is fixedly connected to the rotating column 12. A motor 15 is connected as the core power source of the mixing system. The output end of the motor 15 is fixedly connected to a rotating column 16 to transmit rotational power and ensure stable torque output without fluctuations. One end of the rotating column 16 is fixedly connected to a rotating plate 17 to integrate the mounting structure of rotating plate 18 and enhance the overall rigidity of the rotating mechanism. One end of the rotating plate 17 is fixedly connected to a rotating plate 18. Together with the rotating ball 19, the rotating power of the motor 15 is converted into up-and-down cyclic rotational motion. The outer wall of the rotating ball 19 rotates inside the rotating plate 18, driving the rotating fan 13 fixedly connected to the outer wall of column 12 to generate turbulence to promote uniform dispersion of sand. The outer wall of column 12 is fixedly connected to a scraper 14 to simultaneously scrape off the sediment on the barrel wall and prevent the raw materials from caking. The outer wall of the scraper 14 slides on the inner wall of the mixing barrel 1.

[0037] Working principle: First, pull the connecting rod 3 outward. The connecting rod 3 drives the locking block 8 to move outward, thereby compressing the spring 7. The locking block 8 slides in the second groove 10 and the first groove 6, taking the locking block 8 out of the second groove 10 inside the fixing block 9, thereby releasing the fixing of the fixing block 9 and removing the screen 2. The locking block 8 resets under the rebound of the spring 7, pushing the replacement screen 2 into the outer shell 4. The locking block 8 has an inclined structure. When the fixing block 9 is pushed in, it compresses the locking block 8 inward. The locking block 8 compresses the spring 7. When it reaches the designated position, the spring 7 rebounds and pushes the locking block 8 into the second groove 10, thus fixing the fixing block 9 and achieving the effect of quickly replacing the screen 2.

[0038] When the motor 15 is started, the motor 15 drives the rotating column 16 to rotate. The rotating column 16 drives the rotating plate 17 and the rotating plate 18 to rotate. The rotating plate 18 drives the rotating ball 19 to rotate adaptively inside it, thereby converting the rotational motion of the motor 15 into the up-and-down cyclical rotation of the rotating column 20 and the rotating column 12. The rotating column 12 drives the rotating fan 13 and the scraper 14 to stir and scrape the wall, achieving the effect of stirring and scraping the wall simultaneously during operation.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
