DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 6 , a precise lubricating oil blending and weighing device, comprising a mixing mechanism 1 and a weighing mechanism 2 arranged above the mixing mechanism 1, an angle adjustment mechanism 3 is connected below the mixing mechanism 1, and the mixing mechanism 1 comprises a mixing barrel 101:

[0024] Furthermore, the weighing mechanism 2 includes a weighing cylinder 201, which is rotatably connected to a weighing disk 204 at the upper part of the weighing cylinder 201, and a weighing sensor 205 is provided at the lower part of the weighing disk 204. A first electric push rod 206 is rotatably connected to one side of the weighing cylinder 201, and the telescopic rod of the first electric push rod 206 extends to the inside of the weighing cylinder 201 and is rotatably connected to one side of the weighing disk 204. A quantitative cylinder 208 is fixedly connected to the lower part of the weighing cylinder 201, and a quantitative feeding paddle 209 is rotatably connected to the inner wall of the quantitative feeding paddle 209. A rotating rod 210 is fixedly connected to the inner wall of the quantitative feeding paddle 209, and one end of the rotating rod 210 extends to the outside of the rotating rod 210 and is fixedly sleeved with a second pulley 211.

[0025] The mixing mechanism 1 and the mixing barrel 101 are responsible for containing the base oil and various additives, and ensure that all the ingredients are fully and evenly mixed through a specific mixing method. The angle adjustment mechanism 3 connected below the mixing barrel 101 can facilitate the discharge of the mixed materials from the mixing barrel 101. The core of the weighing mechanism 2 and the weighing cylinder 201 is to achieve accurate measurement. The weighing plate 204 on the top of the weighing cylinder 201 continuously adds materials, and the weighing sensor 205 below it monitors the weight changes of the added materials in real time to ensure the accuracy of the ingredients. The first electric push rod 206 controls the rotation of the weighing plate 204 or the addition of materials through telescopic action, and the weighing system The automatic control of the system can realize the precise control of the feeding speed and total amount according to the formula. The quantitative cylinder 208 and the quantitative feeding paddle 209 are designed for more precise material control, especially for the precise addition of small doses of additives. The quantitative feeding paddle 209 feeds the material into the mixing barrel 101 according to the set amount through the transmission structure of the rotating rod 210 and the second pulley 211 to ensure the constant amount of each addition. This device realizes the full range of accurate metering and mixing from large doses of base oil to small doses of additives through the combination of precise mechanical design and automatic control, and improves the efficiency of lubricant blending and the stability of product quality. Such a system reduces human errors, enhances the controllability and safety of the production process, and is suitable for lubricant production environments with strict requirements on product quality.

[0026] Furthermore, a discharge pipe 102 is fixedly connected to one end of the mixing barrel 101 , and a stirring rod 103 is rotatably connected to the center of the mixing barrel 101 . The stirring rod 103 is located on the inner surface of the mixing barrel 101 and has multiple stirring blades 104 equidistantly arranged thereon.

[0027] The discharge pipe 102 is fixed to one end of the mixing barrel 101, and is used to discharge the mixed lubricating oil to the next process after the blending is completed, such as filling or a temporary storage container. The stirring rod 103 is driven by a power motor 105 and rotates in the center of the mixing barrel 101. The multiple stirring blades 104 equidistantly arranged on its surface generate strong shearing and mixing forces when rotating, ensuring that the ingredients in the barrel are fully mixed and evenly mixed, eliminating stratification and agglomeration, which is crucial for obtaining stable and consistent lubricating oil products.

[0028] Furthermore, one end of the stirring rod 103 extends to the outside of the mixing barrel 101 and is fixedly connected to a power motor 105. The power motor 105 is fixedly arranged on one side of the mixing barrel 101. A first pulley 106 is fixedly sleeved on the surface of the stirring rod 103. The first pulley 106 is connected to a second pulley 211 through a belt 107.

[0029] The power motor 105 is installed on one side of the mixing barrel 101, directly driving the stirring rod 103. Through stirring, the first pulley 106 fixed on the surface of 103 and the second pulley 211 connected to it by the belt 107 form a simple and effective transmission chain. This belt 107 transmission method is more flexible and easy to maintain than direct gear transmission. At the same time, it can also effectively buffer the vibration generated by the operation of the power motor 105, reduce noise, and protect the power motor 105.

[0030] Furthermore, the weighing cylinder 201 is fixedly arranged on one side of the top of the mixing barrel 101 , and the top and bottom of the weighing cylinder 201 are respectively fixedly connected with a feeding pipe 202 and a discharging pipe 203 , and the bottom of the discharging pipe 203 is connected to the top of the mixing barrel 101 .

[0031] The weighing cylinder 201 is fixedly arranged on one side of the top of the mixing barrel 101. This layout is conducive to the weighed materials being directly introduced into the mixing barrel 101 quickly and smoothly by gravity after accurate measurement, thereby reducing the loss and pollution risk during the material transfer process. The feeding pipe 202 is arranged on the top of the weighing cylinder 201 as an inlet for various raw material base oils and additives, which is convenient for adding materials to the weighing cylinder 201 in a closed system, keeping the working environment clean and reducing raw material exposure. The discharge pipe 203 is located at the bottom of the weighing cylinder 201 and is connected to the top of the mixing barrel 101, ensuring that the accurately weighed materials can fall directly into the mixing barrel 101 through the discharge pipe 203. This design simplifies the material transfer steps, improves the blending efficiency, and helps to maintain the accuracy of the material ratio.

[0032] Furthermore, a drainage hopper 207 is fixedly connected to the inner wall of the weighing cylinder 201 , and the drainage hopper 207 is located below the weighing pan 204 and above the quantitative cylinder 208 .

[0033] The drainage hopper 207 is fixedly connected to the inner wall of the weighing cylinder 201, and its position is just below the weighing pan 204 and above the quantitative cylinder 208. The subtlety of this design lies in that when the material on the weighing pan 204 reaches a preset weight, the material can be released into the drainage hopper 207 through the command of the control system.

[0034] Furthermore, a feed port and a discharge port are respectively provided at the top and the bottom of the quantitative cylinder 208 , and a positioning ring 212 is fixedly sleeved on the surface of the weighing cylinder 201 .

[0035] These detailed designs work together to not only optimize the material flow path, but also enhance the precise control capabilities during the blending process. They are an essential component for achieving efficient, high-quality lubricant blending production.

[0036] Furthermore, the angle adjustment mechanism 3 includes a base 301 , which is disposed below the mixing barrel 101 , and a second electric push rod 302 is rotatably connected to one side of the top of the base 301 , and a telescopic end of the second electric push rod 302 is rotatably connected to one side of the bottom of the mixing barrel 101 .

[0037] The mixing barrel 101 is firmly supported by the base 301, and the inclination angle of the mixing barrel 101 is adjusted by utilizing the telescopic function of the second electric push rod 302. The use of the second electric push rod 302 increases the convenience and accuracy of the adjustment. The operator can easily adjust it through the control system without manual operation, which is safe and efficient.

[0038] Furthermore, the front and rear surfaces of the mixing barrel 101 are rotatably connected to a support frame 303 , and the bottom of the support frame 303 is fixedly connected to the top of the base 301 .

[0039] The support frame 303 rotatably connected to the front and rear surfaces of the mixing barrel 101 not only provides necessary physical support, but also ensures that the mixing barrel 101 remains stable when the angle is adjusted to prevent instability caused by tilting. The fixed connection between the support frame 303 and the top of the base 301 strengthens the structural strength of the entire device.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
