[0036] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0037] This utility model relates to a raw material mixer, such as Figures 1 to 5 As shown, it includes:

[0038] Support mechanism 1 is independently and fixedly installed;

[0039] Mixing barrel 2 is installed on support mechanism 1 and can rotate freely along the axis of mixing barrel 2. Mixing barrel 2 is usually cylindrical with a smooth interior, which facilitates the mixing and discharge of raw materials.

[0040] Two mounting shafts 3 are coaxially mounted in the inner holes at both ends of the mixing tank 2, and the mounting shafts 3 and the mixing tank 2 rotate independently;

[0041] The S-shaped stirring paddle 4 is installed on two mounting shafts 3 and is slidably connected to the inner wall of the mixing tank 2. The design of the S-shaped stirring paddle 4 allows the raw materials to be fully stirred during the mixing process, avoiding the accumulation of raw materials or uneven mixing.

[0042] The drive shaft 5 is coaxially rotatably installed in the inner holes of two mounting shafts 3, and multiple sets of stirring blades 6 are equidistantly arranged on the drive shaft 5. The mounting shafts 3 and the drive shaft 5 rotate independently to ensure that the stirring blades 6 and the S-shaped stirring paddle 4 can work together.

[0043] The drive mechanism 7 is mounted on the support mechanism 1 and is used to provide rotational power to the mounting shaft 3 and the transmission shaft 5.

[0044] The power mechanism 8 is installed on the support mechanism 1. The power mechanism 8 is used to flip the mixing tank 2 to facilitate the addition and discharge of raw materials.

[0045] The working principle of this device is as follows:

[0046] First, the raw materials are poured into the mixing tank 2. Then, the drive mechanism 7 is started. The drive mechanism 7 drives the mounting shaft 3 and the transmission shaft 5 to rotate. The rotation of the mounting shaft 3 causes the S-shaped stirring paddle 4 to slide on the inner wall of the mixing tank 2 to initially stir the raw materials. At the same time, the rapid rotation of the transmission shaft 5 drives the stirring blade 6 to further mix the raw materials. Due to the synergistic effect of the S-shaped stirring paddle 4 and the stirring blade 6, the raw materials are fully mixed in the mixing tank 2 to ensure uniform mixing. After mixing is completed, the mixing tank 2 is flipped by the power mechanism 8 to facilitate the discharge of the mixed raw materials.

[0047] The independently fixed support mechanism 1 provides a solid and stable foundation for the entire device. The mixing tank 2 is mounted on the support mechanism 1 and can rotate freely along the axis. Its cylindrical shape and smooth interior design facilitate the tumbling and mixing of raw materials within the tank and ensure smooth discharge of the raw materials after mixing, reducing residue. Two mounting shafts 3 are coaxially mounted in the inner holes at both ends of the mixing tank 2 and rotate independently of the mixing tank 2, providing stable installation and rotation support for the S-shaped stirring paddle 4. The S-shaped stirring paddle 4 is slidably connected to the inner wall of the mixing tank 2. Its unique shape allows it to penetrate into all corners of the raw materials during rotation, effectively preventing material accumulation and dead corner residue. The mixing mechanism significantly improves the uniformity of mixing. The drive shaft 5 is coaxially rotated within the inner hole of the mounting shaft 3, and multiple sets of stirring blades 6 are equidistantly arranged on it. When the drive shaft 5 rotates rapidly, it can perform more detailed and in-depth mixing of the raw materials. Working in conjunction with the S-shaped stirring paddle 4, it further enhances the mixing effect. The drive mechanism 7, mounted on the support mechanism 1, precisely provides stable rotational power to the mounting shaft 3 and the drive shaft 5, ensuring the efficient operation of the mixing components. The power mechanism 8 can easily flip the mixing tank 2, greatly facilitating the addition and discharge of raw materials, improving work efficiency, and comprehensively meeting the needs of efficient and uniform mixing of raw materials.

[0048] As a preferred option, such as Figures 1 to 3 As shown, a material pouring trough 21 is conveniently provided on one side along the length of the mixing tank 2. One end of the material pouring trough 21 is provided with an addition port for adding raw materials into the mixing tank 22. A sealing cap 22 is installed at the addition port to ensure that the raw materials will not leak from the addition port during the mixing process. The sealing cap 22 is convenient for operators to open and close. The other end of the material pouring trough 21 is provided with a discharge port for discharging the mixed raw materials. A control valve 23 is provided on the discharge port to control the discharge of the raw materials.

[0049] The addition port at one end of the pouring trough 21 provides a convenient channel for adding raw materials to the mixing tank. Operators can easily pour the raw materials into the tank through this port. The sealing cap 22 installed at the addition port effectively prevents raw material leakage. The discharge port at the other end of the pouring trough 21 facilitates the discharge of the mixed raw materials, significantly improving the discharge efficiency. The control valve 23 installed on the discharge port allows operators to accurately control the speed and amount of raw material discharge to meet different production needs. The entire structure of the pouring trough 21 comprehensively improves the addition and discharge links in the raw material mixing process. At the same time, the tilting mechanism of the mixing tank 2 is set to prevent the accumulation of raw materials at the addition port and discharge port.

[0050] As a preferred option, such as Figures 1 to 2 As shown, the support mechanism 1 includes:

[0051] The base 11 has support frames 12 on both sides of its top end, and the inner holes on the two support frames 12 are coaxially arranged.

[0052] Two support shafts 13 are rotatably mounted on two support frames 12, and the two support shafts 13 are coaxially mounted at both ends of the mixing tank 2.

[0053] The base 11 is provided with a support foot assembly 14 at its bottom end;

[0054] The base 11 serves as the foundation of the entire support mechanism, and its stable structure provides reliable support for the components above. The support frames 12 on both sides of the top not only connect and position the support shafts 13, but also have coaxial inner holes to ensure the coaxiality of the two support shafts 13. This allows the mixing tank 2 to rotate smoothly after installation, avoiding shaking or jamming caused by installation deviation. The two support shafts 13 are rotatably mounted on the support frames 12 and coaxially connected to both ends of the mixing tank 2, providing flexible and stable support for the free rotation of the mixing tank 2. This ensures that the mixing tank 2 can be smoothly rotated under the action of the power mechanism 8, facilitating the addition and discharge of raw materials. The support foot group 14 set at the bottom of the base 11 further enhances the contact stability between the entire support mechanism 1 and the ground, preventing displacement or tipping of the device during operation due to factors such as vibration and uneven force.

[0055] As a preferred option, such as Figures 1 to 5 As shown, the power mechanism 8 includes:

[0056] A servo motor 81 is mounted on a support frame 12, and a sector gear 82 is mounted on the output end of the servo motor 81;

[0057] The transmission gear 83 is coaxially mounted on a support shaft 13, and the sector gear 82 is meshed with the transmission gear 83.

[0058] The transmission gear 83 and the sector gear 82 mesh once, which drives the mixing tank 2 to rotate 180° via the servo motor 81.

[0059] The servo motor 81 in the power mechanism 8 is mounted on the support frame 12. The sector gear 82 at its output end meshes with the transmission gear 83 coaxially mounted on the support shaft 13. Through a single meshing, the servo motor 81 can precisely drive the mixing tank 2 to rotate 180°, realizing the efficient rotation of the mixing tank 2. This greatly facilitates the addition and discharge of raw materials. Moreover, this precise angle control ensures the stability of the mixing tank 2 during the rotation process, avoiding the impact of excessive or insufficient rotation on the addition and discharge of raw materials.

[0060] As a preferred option, such as Figures 1 to 5 As shown, a limiter 84 is also installed at the output end of the servo motor 81;

[0061] The transmission gear 83 has two limiting grooves at equal angles, and the limiting member 84 is slidably installed with the limiting grooves;

[0062] When the transmission gear 83 meshes with the sector gear 82, the limiting member 84 is disengaged from the limiting groove of the transmission gear 83.

[0063] The limiting component 84 installed at the output end of the servo motor 81 is slidably installed with two limiting grooves set at equal angles on the transmission gear 83. When the transmission gear 83 meshes with the sector gear 82, the limiting component 84 disengages from the limiting groove. In the non-meshing state, the limiting component 84 can accurately fall into the limiting groove, playing a reliable positioning and limiting role. This ingenious design effectively avoids unnecessary rotation of the mixing tank 2 due to accidental shaking or external force when it is not in operation, ensuring the safety of the operator and the surrounding environment. At the same time, it also ensures that the mixing tank 2 is in the preset initial position before each work start, providing a strong guarantee for accurately controlling the flipping angle and workflow of the mixing tank 2.

[0064] As a preferred option, such as Figures 1 to 5 As shown, the drive mechanism 7 includes:

[0065] The drive motor 71 is mounted on a support frame 12, and the output end of the drive motor 71 is coaxially mounted with a first gear 72 and a second gear 73 respectively.

[0066] The third gear 74 is coaxially mounted on the mounting shaft 3, and the third gear 74 is meshed with the first gear 72.

[0067] The fourth gear 75 is coaxially mounted on the transmission shaft 5, and the fourth gear 75 is meshed with the second gear 73.

[0068] The support frame 12 is provided with an isolation member 76, and the fourth gear 75 and the second gear 73 are located inside the isolation member 76;

[0069] In the drive mechanism 7, the drive motor 71 is mounted on the support frame 12. The first gear 72 and the second gear 73, which are coaxially mounted on the output end, mesh with the third gear 74, which is coaxially mounted on the mounting shaft 3, and the fourth gear 75, which is coaxially mounted on the transmission shaft 5. Through this gear transmission structure, the drive motor 71 can accurately and efficiently transmit power to the mounting shaft 3 and the transmission shaft 5, so as to achieve stable rotation of the two, thereby driving the S-shaped stirring paddle 4 and the stirring blade 6 to work together and provide strong power for mixing raw materials. At the same time, the isolation piece 76 set on the support frame 12 encloses the fourth gear 75 and the second gear 73, effectively preventing dust, impurities and other foreign objects from entering the gear meshing area, reducing gear wear and extending gear service life.

[0070] The raw material mixer of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0071] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
