[0005] To achieve the above objectives, the present invention adopts the following technical solution: a color mixing machine for uniform mixing, comprising a color mixing tank, a mounting base installed on the top of the color mixing tank, a motor fixedly installed on the top of the mounting base, the output shaft of the motor extending into the color mixing tank and connected to a stirring device, the stirring device comprising a drive wheel and a connecting rod, a toothed ring meshing on the outer wall of the drive wheel, a connecting ring connected to the inner wall of the toothed ring, a rotating cylinder connected to the bottom of the connecting ring, a plurality of through holes opened on the side wall of the rotating cylinder, and a connecting rod rotatably connected in the through holes, a second bevel gear and a stirring plate respectively connected to both ends of the connecting rod, and a plurality of first bevel gears connected to the outer wall of the connecting rod.

[0020] 2. In this utility model, by setting up a scraping device, the rotating cylinder drives the rotating rod to rotate. The rotating rod slides in the limiting groove through the limiting block, driving the rotating cylinder to rotate. This causes the rotating cylinder to drive the scrapers on both sides to rotate, which agitates the raw material at the bottom of the mixing tank. Furthermore, because the scraper is an arc plate, the raw material moves towards the center through the arc of the scraper during discharge and is discharged from the discharge chute. This ensures that the raw material at the bottom of the mixing tank can be fully discharged, avoiding long-term accumulation that could affect reuse. Attached Figure Description

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4This utility model provides a technical solution: a color mixing machine for uniform mixing, including a color mixing tank 1, a mounting base 3 installed on the top of the color mixing tank 1, a motor 2 fixedly installed on the top of the mounting base 3, the output shaft of the motor 2 extending into the color mixing tank 1 and connected to a stirring device 4, the stirring device 4 including a drive wheel 401 and a connecting rod 405, a toothed ring 403 meshing on the outer wall of the drive wheel 401, a connecting ring 402 connected to the inner wall of the toothed ring 403, a rotating cylinder 404 connected to the bottom of the connecting ring 402, and a plurality of through holes opened on the side wall of the rotating cylinder 404, with connecting rods rotatably connected inside the through holes. 409, the two ends of the connecting rod 409 are respectively connected to the second bevel gear 408 and the stirring plate 406. The outer wall of the connecting rod 405 is connected to multiple first bevel gears 407. One side of the drive wheel 401 is connected to the output shaft of the motor 2, and the top of the connecting ring 402 is rotatably connected to the top of the inner wall of the mixing tank 1. The top of the connecting rod 409 extends out of the rotating cylinder 404, and the top of the connecting rod 405 passes through the connecting ring 402 and is connected to the top of the inner wall of the mixing tank 1. The outer wall of the first bevel gear 407 meshes with the corresponding outer wall of the second bevel gear 408, and the cross section of the stirring plate 406 is cross-shaped.

[0028] In a specific implementation, an agitator 4 is provided. The output shaft of the motor 2 drives the drive wheel 401 to rotate, which in turn drives the gear ring 403 to rotate. The gear ring 403 drives the connecting ring 402 to rotate, which in turn drives the rotating cylinder 404 at the bottom to rotate. This causes the rotating cylinder 404 to drive the connecting rod 409 inside the through hole to rotate. One end of the connecting rod 409 drives the agitator 406 to rotate, allowing the agitator 406 to perform large-scale rotation and stirring. Then, a connecting pipe passes through the connecting ring 402 and is connected to the top of the inner wall of the color mixing tank 1. The connecting rod 409 is fixedly connected, so that the other end of the connecting rod 409 drives the second bevel gear 408 to move on the outer surface of the first bevel gear 407, thereby causing the second bevel gear 408 to rotate. Then, the second bevel gear 408 drives the stirring plate 406 to rotate through the connecting rod 409, so that the stirring plate 406 performs small-range rotational stirring, thereby improving the stirring and mixing efficiency of the device. By setting the stirring plate 406 as a cross stirring plate, the stirring and mixing force can be increased when the cross stirring plate 406 rotates, thereby further improving the stirring and mixing efficiency.

[0029] The bottom of the color mixing tank 1 is provided with a discharge chute 6, and the bottom of the discharge chute 6 is provided with a discharge valve. The bottom of the rotating cylinder 404 is connected to a scraping device 5. The scraping device 5 includes a rotating cylinder 506. The inner wall of the rotating cylinder 506 is provided with two limiting grooves 507, and the limiting blocks 502 are slidably connected in the limiting grooves 507. The two limiting blocks 502 are connected to the same rotating rod 501. The top of the rotating rod 501 is connected to the bottom of the rotating cylinder 404. The outer wall of the rotating cylinder 506 is connected with two scrapers 503. The bottom of the scrapers 503 is in contact with the bottom of the inner wall of the color mixing tank 1, and the scrapers 503 are arc-shaped. The bottom of the rotating rod 501 is provided with a fixing groove, and the fixing groove is slidably connected to a support rod 504. The bottom of the support rod 504 is connected to the bottom of the inner wall of the rotating cylinder 506. The outer wall of the support rod 504 is fitted with a spring 505. The two ends of the spring 505 are respectively connected to the bottom of the rotating rod 501 and the bottom of the inner wall of the rotating cylinder 506.

[0030] In a specific implementation, a scraping device 5 is provided. The rotating cylinder 404 drives the rotating rod 501 to rotate, and the rotating rod 501 drives the limiting block 502 to rotate. The limiting block 502 slides in the limiting groove 507, causing the limiting block 502 to drive the rotating cylinder 506 to rotate. The rotating cylinder 506 drives the scrapers 503 on both sides to rotate. By setting the scrapers 503 to be arc-shaped, and the guiding direction of the arc is towards the center point, the raw materials can be concentrated and moved towards the center point during discharge, thereby ensuring the discharge efficiency. Furthermore, the scrapers 503 scrape the bottom of the color mixing tank 1, so that the raw materials at the bottom of the color mixing tank 1 can be fully discharged, avoiding long-term accumulation that affects reuse. By setting the elasticity of the spring 505, the spring 505 drives the bottom of the scraper 503 to fit tightly against the bottom of the color mixing tank 1 through the rotating cylinder 506, thereby ensuring the scraping efficiency.

[0031] Working principle: During use, the raw materials to be mixed are poured into the mixing tank 1 from the top. Then, the motor 2 drives the drive wheel 401 to rotate, which in turn drives the gear ring 403 to rotate. The gear ring 403 drives the connecting ring 402 to rotate, which in turn drives the rotating cylinder 404 to rotate. The rotating cylinder 404 drives the connecting rod 409 inside the through hole to rotate, which in turn drives the stirring plate 406 to rotate, causing the stirring plate 406 to perform large-scale stirring. At the same time, the connecting rod 409 drives the second bevel gear 408 to move on the outer wall of the first bevel gear 407, causing the first bevel gear 407 to drive the second bevel gear 408 to move on the outer wall of the first bevel gear 407. The rotation of wheel 408 causes the second bevel gear 408 to drive the stirring plate 406 to rotate via connecting rod 409, thereby increasing the stirring mode of the stirring plate 406 and improving the mixing efficiency. During discharge, the rotating cylinder 404 drives the rotating rod 501 to rotate, the rotating rod 501 drives the limiting block 502 to rotate, the limiting block 502 drives the rotating cylinder 506 to rotate, which in turn drives the scraper 503 to rotate, and the scraper 503 scrapes and guides the raw material at the bottom of the color mixing tank 1, so that the raw material at the bottom of the color mixing tank 1 is fully discharged.
