Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil homogenization, and particularly relates to a three-roll mill automatic homogenization device. Background Technique

[0002] Lubricating oil usually needs to be homogenized before use to ensure that its performance and effect can reach the best state. Homogenizing lubricating oil helps to ensure the uniform distribution of various additives and components in the oil and avoid precipitation or stratification in the oil. In industrial production, after the lubricating oil is homogenized, its quality and performance are more stable, and it can provide better lubrication effect and the function of protecting the machine. The post-treatment of lubricating grease is very important for the performance of the product;

[0003] Under the prior art, a Chinese patent with the application number of "201510925495.3" discloses a lubricating oil stirring tank, including a tank body. There is a feed inlet above the tank body, and a discharge outlet below the tank body. There are legs at the lower part of the tank body. There is a motor at the upper part of the tank body. The motor is connected to a shaft. There are blades for stirring lubricating oil on the shaft. The blades arranged on the shaft include blade A and blade B. Blade A is arranged in the middle of the shaft, and blade B is arranged at the lower end of the shaft. Blade A is of paddle type, and blade B is of downward anchor type; there is a jacket outside the tank body, and there are jacket inlets and jacket outlets on the jacket; there is a manhole on the tank body; the motor and the shaft are connected through a coupling; the utility model provides a lubricating oil stirring tank. The utility model is used for stirring the base oil and additives of lubricating oil. The blades on the shaft include paddle blades and anchor blades, and the stirring is more uniform and the stirring effect is better.

[0004] The above patent can homogenize lubricating oil to a certain extent. However, in actual operation, for some products with higher requirements, the homogenization degree of the stirring type is insufficient. The roll grinding type can make the lubricating grease more uniform and delicate compared with the stirring type. However, the roll grinding type needs to be fed manually through roll grinding and cannot be closed as a whole, so there is a risk of impurities entering the lubricating oil. Moreover, the traditional roll grinding cannot adjust the grinding degree of the lubricating oil, and different roll mills need to be replaced, resulting in higher production costs and reduced overall work efficiency. It is necessary to improve the prior art. For this reason, we propose a three-roll mill automatic homogenization device to solve the above problems. Content of the Utility Model

The plurality of rotating rollers 201 are respectively fixedly connected to both ends of the plurality of grinding rollers 101. The plurality of rotating rollers 201 are symmetrically distributed along the axis of the grinding roller 101. One end of the rotating roller 201 away from the grinding roller 101 extends through the grinding groove 107 into the homogenizer 1.

[0038] Working principle

[0039] During the actual use process, the driving member drives the connecting belt 205 to move, thereby driving a plurality of driven pulleys 204 to start working, and rotating a plurality of rotating rollers 201. These rotating rollers 201 are fixedly connected to both ends of a plurality of grinding rollers 101 and are symmetrically distributed along the axis of the grinding roller 101. Thus, when the rotating rollers 201 rotate, they make the grinding rollers 101 start working through the connecting belt 205. The user adjusts the contact point between the connecting roller 207 and the trigger wheel 208 to change the tension degree of a plurality of driven pulleys 204, thereby adjusting the distance between a plurality of grinding rollers 101 and the distance from the grinding groove 107. In this way, the homogenizing effect and fineness can be controlled;

[0040] A variety of sensors are installed in the driving member, which can observe the working temperature, rotation speed and current magnitude, and at the same time, the working time is displayed on the instrument;

[0041] In addition, the connecting roller 207 is also connected to the driven gear 211. Thus, through the transmission of the driving gear 212, the fixed roller 213 can be rotated. The fixed roller 213 is rotatably connected to the homogenizer 1 and can be easily adjusted by the user through the screw wheel 221. In this way, the user can adjust the distance between the grinding rollers 101 by rotating the screw wheel 221, making the adjustment process more precise and labor-saving. During the working process, the fixed disk 216 is fixedly connected to the connecting disk 214 through the limiting roller 220 and the mounting groove 217, thereby ensuring the stability of the connecting disk 214 and the fixed roller 213. In this way, after the user completes the adjustment, the device can remain stable, preventing the instrument panel 209 from moving, thus ensuring the stability of the working process.

[0042] The overall device is automated, saving manpower and eliminating the need for manual feeding, thereby improving work efficiency. It can be equipped with a housing, reducing the risk of introducing impurities. By adjusting the connecting roller 207 and the screw wheel 221, the user can easily adjust the distance between the grinding rollers 101, making the adjustment process more precise and labor-saving. By stabilizing the connecting disk 214 and the fixed roller 213 through the fixed disk 216, the device is ensured to remain stable during the working process, improving the working effect. The homogenization effect and fineness of the lubricating oil can be changed according to the user's own usage requirements.
