[0002] A lubricating oil stirring structure refers to a mixture of base oil and additives formulated according to a predetermined formula, which undergoes physical mixing and preliminary physicochemical treatment in a stirring structure to achieve specific performance indicators.

[0003] Most existing mixing structures involve placing the mixing paddle inside a mixing tank for rotation and mixing. However, due to the relatively viscous concentration of lubricating oil, this method can easily result in dead zones in the material located at the corners of the mixing tank's side wall, thus reducing the mixing efficiency of the device.

[0004] Therefore, it is necessary to provide a new lubricating oil stirring structure to solve the above-mentioned technical problems. Utility Model Content

An upper hydraulic cylinder is fixedly installed on the top of the top plate, and the top end of the upper hydraulic cylinder is fixedly connected to the mounting frame. A lower hydraulic cylinder is fixedly installed on the bottom of the chassis, and the bottom end of the lower hydraulic cylinder is fixedly connected to the mounting frame.

[0009] Preferably, the center of the top of the mounting plate has a through hole structure, and docking sleeves are fixedly installed on both sides of the top of the mounting plate. A docking block is inserted inside the docking sleeve. The bottom end of the docking block passes through the mounting plate and is fixedly connected to the top of the docking plate. The docking block and the docking cylinder are fixed by bolts.

[0010] Preferably, a stirring motor for driving the stirring paddle to rotate is fixedly installed on the top of the mounting plate by compression.

[0014] Compared with related technologies, the lubricating oil stirring structure provided by this utility model has the following beneficial effects: 1.

[0019] 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.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 5The present invention provides a lubricating oil stirring structure, which includes: a mounting frame 1, a stirring tank 2 fixedly connected inside the mounting frame 1, a driving component 4 for extruding raw materials inside the stirring tank 2, and multiple sets of stirring components 5 for mixing raw materials inside the stirring tank 2.

[0022] In the embodiments of this utility model, please refer to Figures 1 to 5 The drive assembly 4 includes a top plate 41 and a bottom plate 42. The side walls of the top plate 41 and the bottom plate 42 are slidably connected to the inner wall of the mixing tank 2. The mixing tank 2 is also provided with a slidably connected partition 3. The partition 3 is located between the top plate 41 and the bottom plate 42, and a number of flow holes 31 for raw material flow are opened in the partition 3. An upper hydraulic cylinder 411 is fixedly installed on the top of the top plate 41. The top end of the upper hydraulic cylinder 411 is fixedly connected to the mounting frame 1. A lower hydraulic cylinder 421 is fixedly installed on the bottom of the bottom plate 42. The bottom end of the lower hydraulic cylinder 421 is fixedly connected to the mounting frame 1. A discharge hole 422 is opened at the bottom of the bottom plate 42, and a sealing plate 423 for sealing is installed in the discharge hole 422 through a threaded structure.

[0023] It should be noted that before stirring, the upper hydraulic cylinder 411 and the lower hydraulic cylinder 421 can be extended and retracted to drive the corresponding top plate 41 and bottom plate 42 to move respectively. When the top plate 41 and the bottom plate 42 abut against the top and bottom of the partition plate 3 respectively, various raw materials can flow through the flow holes 31 in the partition plate 3 to the other side of the partition plate 3, thereby realizing the spraying and turning of various raw materials. This extrusion-driven turning method can reduce the phenomenon of dead corner residue of raw materials in the mixing tank 2. Furthermore, by combining with the subsequent stirring paddle 53, the stirring and mixing effect of the device on the lubricating oil can be improved. It should also be noted that: by adjusting the baffle 3, top plate 41, and bottom plate 42, after the lubricating oil is stirred, the baffle 3, top plate 41, and bottom plate 42 are moved out of the mixing tank 2. During this movement, the side walls of the baffle 3, top plate 41, and bottom plate 42 can scrape the lubricating oil from the inner wall of the mixing tank 2, thus ensuring more thorough dispensing of the lubricating oil. In this embodiment, sealing rings are fitted on the side walls of the partition 3, the top plate 41 and the bottom plate 42, so that when the partition 3, the top plate 41 and the bottom plate 42 abut against the inner wall of the mixing tank 2, the sealing effect of the mixing tank 2 can be improved, thereby avoiding the phenomenon of random leakage of raw materials. Meanwhile, through the opening of the discharge hole 422 on the chassis 42, after the lubricating oil is stirred and mixed, the sealing plate 423 can be removed, allowing the lubricating oil to flow out smoothly.

[0024] In the embodiments of this utility model, please refer to Figures 1 to 5The mixing assembly 5 includes a fixed frame 51, the bottom of which is fixedly connected to the top of the top plate 41. A driving hydraulic cylinder 511 is fixedly mounted on the top of the fixed frame 51, and a mounting plate 52 is fixedly connected to the bottom of the driving hydraulic cylinder 511. A docking plate 541 is movably connected to the bottom of the mounting plate 52. A mixing paddle 53 for mixing lubricating oil raw materials is rotatably mounted on the bottom of the docking plate 541. A docking cylinder 54 is rotatably connected to the top of the docking plate 541. The bottom end of the docking cylinder 54 passes through the docking plate 541 and is fixedly connected to the top of the mixing paddle 53. A sealing plate 531 is fixedly connected to the bottom of the mixing paddle 53. The center of the top of the mounting plate 52 has a through hole structure, and docking sleeves are fixedly mounted on both sides of the top of the mounting plate 52. 523, a docking block 542 is inserted inside the docking sleeve 523. The bottom end of the docking block 542 passes through the mounting plate 52 and is fixedly connected to the top of the docking plate 541. The docking block 542 and the docking cylinder 54 are fixed together by bolts. The top of the mounting plate 52 is fixedly installed with a stirring motor 521 that drives the stirring paddle 53 to rotate by compression. The output end of the stirring motor 521 is fixedly installed with a hexagonal drive rod 522. The hexagonal drive rod 522 is inserted into the docking cylinder 54. The inner cavity of the docking cylinder 54 is adapted to the outer wall of the hexagonal drive rod 522. The top of the top plate 41 has multiple through holes 412. The diameter of the through holes 412 is the same as the diameter of the sealing plate 531. The diameter of the through holes 412 is smaller than the diameter of the mounting plate 52.

[0025] It should be noted that: since the mixing paddle 53 is set below the mounting plate 52 through the docking plate 541, and since the docking plate 541 is inserted into the docking sleeve 523 through the top docking block 542, when the operator removes the screw between the docking block 542 and the docking sleeve 523, the restriction on both can be released. At this time, the operator only needs to hold the mixing paddle 53 and apply downward force to achieve flexible disassembly of the mixing paddle 53, which facilitates the operator to clean the mixing paddle 53 later. In this embodiment: by setting a relatively large mounting plate 52, when the stirring paddle 53 moves to below the top plate 41 and the mounting plate 52 abuts against the top plate 41, the through hole 412 in the top plate 41 can be blocked and sealed, thereby preventing the raw material from overflowing from the inside of the mixing tank 2 through the through hole 412 when the stirring paddle 53 is stirring and mixing, thus achieving stable stirring and mixing of the raw material; It should also be noted that a sealing rubber ring is fitted on the side wall of the sealing disc 531, so that when the sealing disc 531 moves into the through hole 412, the sealing disc 531 can smoothly seal the through hole 412, thereby forming an integral structure on the lower surface of the top disc 41. In this way, when the top disc 41 squeezes the raw material, the raw material can be prevented from overflowing through the through hole 412.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 5 A connecting rod 32 is fixedly connected to the top of the top plate 41. The top end of the connecting rod 32 extends above the top plate 41, and the outer wall of the connecting rod 32 abuts against and slides against the inner wall of the through hole on the top plate 41. A sliding piece 33 is fixedly connected to the top of the connecting rod 32. A top frame 11 is fixedly connected to the top of the mounting frame 1. A suspension hydraulic cylinder 12 is fixedly connected to the top of the top frame 11. The bottom end of the suspension hydraulic cylinder 12 is fixedly connected to the top of the sliding piece 33, and the sliding piece 33 slides through the through hole opened at the top to slide against the outer wall of the support rod in the top frame 11.

[0027] It should be noted that: through the sliding connection between the sliding plate 33 and the top frame 11, when the suspension hydraulic cylinder 12 drives the sliding plate 33, the sliding plate 33 can drive the partition plate 3 to move inside the mixing tank 2 through the connecting rod 32. Therefore, the partition plate 3 can be stably driven, which makes it easier for personnel to clean the flow holes 31 in the partition plate 3 later.

[0028] The working principle of the lubricating oil stirring structure provided by this utility model is as follows: When using this device, the operator can first add various raw materials for lubricating oil into the mixing tank 2. After the raw materials are added, the operator can control the upper hydraulic cylinder 411 to extend. The extended upper hydraulic cylinder 411 will drive the top plate 41 to slide downward inside the mixing tank 2. At this time, the side wall of the sliding top plate 41 will abut against the inner wall of the mixing tank 2, thereby scraping off the raw material adhering to the inner wall of the mixing tank 2. When the bottom of the top plate 41 abuts against the top of the partition 3, the raw material on the partition 3 can flow through the flow hole 31 in the partition 3 to the bottom of the partition 3, and then the upper hydraulic cylinder 411 can be controlled to retract and reset. After the top plate 41 is reset, the lower hydraulic cylinder 421 can be extended, thereby driving the bottom plate 42 to move upward in the mixing tank 2. When the top of the bottom plate 42 abuts against the bottom of the partition plate 3, various raw materials can flow through the flow hole 31 to the top of the partition plate 3. Through the repeated movement of the top plate 41 and the bottom plate 42, various raw materials can be sprayed and turned up and down, thereby reducing the phenomenon of raw materials adhering to the inner wall of the mixing tank 2 and leaving dead corners. Then the top of the chassis 42 can be kept abutting against the top of the partition 3. During this process, the drive hydraulic cylinder 511 can be extended. The extended drive hydraulic cylinder 511 will drive the stirring paddle 53 through the mounting plate 52 to move into the mixing tank 2 until the bottom of the mounting plate 52 abuts against the top of the top plate 41. Then the extension of the drive hydraulic cylinder 511 can be stopped, and the through hole 412 in the top plate 41 can be blocked by the mounting plate 52. At this time, the stirring motor 521 can be controlled to rotate. The rotating stirring motor 521 will drive the docking cylinder 54 to rotate within the docking plate 541 by the hexagonal drive rod 522 at the output end abutting against the docking cylinder 54. The rotating docking cylinder 54 will then drive the stirring paddle 53 to rotate, thereby achieving the stirring and mixing of the raw materials inside the stirring cylinder. Through the cooperation of the stirring component 5 and the drive component 4, the stirring and mixing effect of the device on the lubricating oil raw materials can be improved. After the lubricating oil is stirred, the lower hydraulic cylinder 421 can be controlled to retract, so that the chassis 42 moves to the bottom of the mixing tank 2. Then the sealing plate 423 can be turned to move it out of the chassis 42. At this time, the lubricating oil in the mixing tank 2 will flow downward through the discharge hole 422 to discharge. After the lubricating oil in the mixing tank 2 has been discharged naturally, the mixing paddle 53 can be controlled to rotate, thereby throwing out the lubricating oil adhering to the mixing paddle 53 by centrifugal force, reducing the residual lubricating oil on the outer wall of the mixing paddle 53. Then, the drive hydraulic cylinder 511 can be controlled to retract, so that the sealing plate 531 and the mixing paddle 53 on its top can be moved to the top plate 41. Next, the lower hydraulic cylinder 421 can be controlled to retract, moving the chassis 42 out of the mixing tank 2. This makes it easier for workers to clean the residual lubricating oil on the top of the chassis 42. After cleaning the residual lubricating oil in this area, a collection frame can be placed on the top of the chassis 42. Then, the suspension hydraulic cylinder 12 and the upper hydraulic cylinder 411 can be controlled to extend, thereby moving the partition 3 and the top plate 41 out of the mixing tank 2 in sequence. During this process, the side walls of the moving partition 3 and the top plate 41 will scrape and clean the residual lubricating oil on the inner wall of the mixing tank 2 by abutting against it, thus making the discharge of lubricating oil more thorough. After the top plate 41 is moved to the outside, the screw between the docking block 542 and the docking sleeve 523 can be unscrewed to release the restriction on both. At this time, the personnel can hold and remove the stirring paddle 53, which makes it easier for the personnel to clean the stirring paddle 53 later. This completes the use of the device.

[0029] In this invention, multiple hydraulic cylinders are connected to a standard hydraulic system via external pipelines to achieve their extension and retraction control. The specific setup of this hydraulic system is conventional technology in the field. In addition, the circuit involved in this invention is controlled by a PLC controller. The PLC sends control signals to the motor driver and hydraulic solenoid valve in sequence according to a preset program to drive the motor and hydraulic cylinders. The circuits and controls involved are all existing technologies and will not be described in detail here.

[0030] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
