[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] First Embodiment

[0024] Please see Figures 1-4 This utility model provides a technical solution: a raw material mixing equipment for paint production and processing, including a mixing tank 1, a tank cover 2 detachably provided on the top of the mixing tank 1, a first feed cylinder 6 for injecting liquid and a second feed cylinder 11 for injecting solids and powders respectively provided on the top of the tank cover 2, and a discharge port opened at the bottom of the mixing tank 1.

[0025] A sealing gasket is provided between the lid 2 and the mixing tank 1 to further enhance the sealing performance.

[0026] The first feed cylinder 6 is made of a transparent material, such as plexiglass, to facilitate operators' observation of the injection of liquid raw materials. A flow meter is installed on the first feed cylinder 6 to accurately measure the volume of the injected liquid raw materials, ensuring that the amount of liquid raw materials added each time meets the process requirements.

[0027] The top of the feed cylinder is equipped with a feeding port for easy addition of raw materials by operators. A dust cover is installed at the feeding port to prevent dust from flying and polluting the environment during the feeding process.

[0028] The bottom of the can lid 2 is equipped with a scraper 16 for cleaning the side wall of the mixing tank 1, which can be raised and lowered. The top of the can lid 2 is equipped with two drive components for raising and lowering the scraper 16. Both sides of the scraper 16 are provided with feeding ports. The bottom of the scraper 16 is provided with several nozzles 23 for cleaning the side wall of the mixing tank 1 at intervals and at an angle. The middle of the can lid 2 is provided with a vertically detachable rotating shaft 19. The bottom of the rotating shaft 19 is fixedly connected with a stirring blade 20 for mixing raw materials.

[0029] In this embodiment, after mixing is completed, the drive component immediately drives the scraper 16 to descend, so that it fits against the side wall of the mixing tank 1. At the same time, the surface of the tank is powerfully rinsed by the nozzle 23 to prevent the material from solidifying on the surface of the mixing tank 1 and further scrape off the residual dirt, achieving a comprehensive cleaning effect.

[0030] According to the paint production formula requirements, the required amount of liquid raw materials are first injected through the first feed cylinder 6. After the liquid raw materials are injected, solid and powdered raw materials are added through the second feed cylinder 11. After confirming that all raw materials have been added, the stirring blade 20 is driven to rotate to mix the raw materials. After the paint is mixed, the valve at the outlet is opened to discharge the mixed paint. The drive assembly is immediately started to drive the scraper 16 to descend, so that it is in contact with the side wall of the mixing tank 1. At the same time, the surface is strongly rinsed by the spray nozzle 23 to prevent the material from solidifying on the surface of the mixing tank 1 and to further scrape off the residual dirt, achieving a comprehensive cleaning effect.

[0031] Please refer to Figure 1 and Figure 2 Furthermore, the top surface of the mixing tank 1 is provided with several first mounting plates 3 at intervals, and the bottom surface of the tank cover 2 is provided with several second mounting plates 4 that fit against the first mounting plates 3 at intervals. Both the first mounting plates 3 and the second mounting plates 4 are provided with threaded holes 14, and the tank cover 2 and the mixing tank 1 can be fixed by screwing bolts into the threaded holes 14.

[0032] In this embodiment, the can lid 2 is slowly lifted to directly above the mixing tank 1 using a hoisting device, and the can lid 2 is slowly lowered so that the second mounting plate 4 gradually approaches the first mounting plate 3. Starting from one of the mounting plate pairs, the bolts are slowly screwed into the threaded holes 14 of the first mounting plate 3 and the second mounting plate 4, and all the bolts are tightened in a cross-symmetrical order.

[0033] Please refer to Figure 1 Furthermore, a support plate 8 is fixedly connected to the top of the first feed cylinder 6, and an electric telescopic rod 9 is fixedly connected vertically to the bottom of the support plate 8. The bottom end of the electric telescopic rod 9 extends into the first feed cylinder 6 and is fixedly connected to a push plate. A liquid injection pipe 7 is connected to one side of the first feed cylinder 6.

[0034] In this embodiment, after an appropriate amount of liquid material is injected into the first feed cylinder 6, the valve on the liquid conveying pipeline is closed, causing the electric telescopic rod 9 to extend and push the push plate downward, pushing the liquid material in the first feed cylinder 6 into the subsequent equipment or pipeline. During the pushing process, the movement speed and pushing force of the electric telescopic rod 9 should be controlled according to actual needs to ensure that the pushing process is stable and uniform.

[0035] Please refer to Figure 1 and Figure 2 Furthermore, a cylinder cover 12 is detachably provided on the top of the second feed cylinder 11, and a handle 13 is fixedly connected to the top of the cylinder cover 12. A pull ring 5 is provided on the side wall of the can cover 2 and between the two second mounting plates 4.

[0036] The main function of the cylinder cover 12 is to seal the second feed cylinder 11 to prevent moisture, dust and other impurities in the air from entering the tank and contaminating the raw materials. It can also prevent the powder raw materials from getting damp and clumping or scattering when stored or waiting to be fed.

[0037] In this embodiment, the core function of the pull ring 5 is to provide a lifting point for the hoisting equipment. Since the can lid 2 integrates multiple components such as the drive assembly, scraper 16, and feed cylinder, its overall weight is quite large. When it is necessary to open the can lid 2 for maintenance or deep cleaning, it is necessary to use lifting equipment such as overhead cranes, forklifts, or manual hoists. The pull ring 5 is a standard lifting point designed for such operations.

[0038] Please refer to Figure 1 and Figure 5 Furthermore, a first motor 15 is vertically arranged in the middle of the top of the can lid 2. The output shaft of the first motor 15 is fixedly connected to a connecting shaft 18. The connecting shaft 18 has a hollow structure and a threaded groove 21 is provided inside the connecting shaft 18. The top end of the rotating shaft 19 is provided with a threaded rod 22 that is threadedly connected to the threaded groove 21.

[0039] In this embodiment, after the threaded rod 22 is fully screwed in, a pin needs to be inserted laterally into the connecting shaft 18 and the threaded rod 22 to prevent the threaded rod 22 from dislodging from the threaded groove 21 when the connecting shaft 18 rotates at high speed.

[0040] Please refer to Figure 6 and Figure 7Furthermore, the drive assembly includes a drive housing 10, a rack plate 25, and a second motor 17. The drive housing 10 is vertically disposed on one side of the top of the can lid 2. The rack plate 25 is slidably connected to the side wall of the drive housing 10. The second motor 17 is horizontally disposed inside the drive housing 10. The output shaft of the second motor 17 is fixedly connected to a gear 24 that meshes with the rack plate 25. A connecting rod 26 is fixedly connected to the rear side of the rack plate 25. One end of the connecting rod 26 is fixedly connected to the top of the scraper 16.

[0041] In this embodiment, when it is necessary to clean the inner wall of the mixing tank 1, the second motor 17 is started to drive its output shaft to rotate. Since its output shaft is fixedly connected to the gear 24, the gear 24 is driven to rotate synchronously. When the gear 24 rotates, it drives the rack plate 25 that meshes with it to descend. Finally, the scraper 16 is driven to descend synchronously through the connecting rod 26, thereby cleaning its side wall and avoiding the problem of impurities remaining on the side wall of the mixing tank 1.

[0042] The working principle and usage process of this utility model are as follows: After the utility model is installed, according to the paint production formula requirements, the required amount of liquid raw materials are first injected through the first feed cylinder 6. After the liquid raw materials are injected, solid and powdered raw materials are added through the second feed cylinder 11. After confirming that all raw materials have been added, the stirring blade 20 is driven to rotate to mix the raw materials. After the paint is mixed, the valve at the outlet is opened to discharge the mixed paint. The drive assembly is immediately started to drive the scraper 16 to descend, so that it is in contact with the side wall of the mixing tank 1. At the same time, the surface is strongly rinsed by the nozzle 23 to prevent the material from solidifying on the surface of the mixing tank 1 and further scrape off the residual dirt to achieve a comprehensive cleaning effect.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
