[0002] Grease is a thick, greasy semi-solid; it is used for the friction parts of machinery to play a lubricating and sealing role. It is also used on metal surfaces to fill voids and prevent rust; during the production process of lubricating oil, the raw materials of lubricants usually undergo strict screening and treatment to ensure their quality and purity.

A roller is installed at the bottom end face of each support column, and all four rollers are in contact with the ground. Since a baffle is inserted into the box body, and the top end face of the baffle is in contact with the bottom end face of the guide plate; the baffle is of an L-shaped structure, and the top end face of the bent part of the baffle is elastically in contact with the bottom end face of the protective block A, so that the baffle can be tightly pressed and prevented from loosening through the protective block A, solving the problems that, firstly, during the crushing and grinding of lubricating oil raw materials, some raw materials are likely to adhere to the inside of the grinding device, thereby affecting the grinding quality and efficiency; secondly, during the grinding process, the grinding roller is prone to severe wear after long-term operation, thereby affecting its service life. However, when the above device is grinding, it is difficult to adjust the grinding accuracy according to the process requirements, thereby affecting the production requirements. At the same time, during the adjustment, it lacks protection for the inner wall of the workbench, so it is necessary to clean the lubricating oil raw materials adhering to its inner wall, which affects the production progress. Therefore, a raw material grinding device for lubricating oil production is proposed to solve the above-mentioned problems. Summary of the Invention

Limiting blocks are respectively fixedly connected to the front and back surfaces of the two right scraping plates and are slidably connected to the front and back surfaces of the inner wall of the workbench through the limiting blocks. When processing the lubricating oil raw material, the lubricating oil raw material is placed into the raw material hopper, and then the three motors are started to work, and their rotation directions and speeds are controlled. The left and right two grinding rollers are driven to rotate towards each other, and then the rotation of the right grinding roller is controlled to be opposite to that of the middle grinding roller for grinding, and the rotation speeds of the three grinding rollers are controlled. At this time, the lubricating oil raw material will be driven by the left and right two grinding rollers and fall onto them for grinding. At the same time, the compound lubricating oil raw material falls onto the right grinding roller. According to the requirements of the production process, by adjusting the rotation of one threaded rod and transmitting through a gear set, using three bevel gears that mesh and drive each other to drive the rotation of the other threaded rod, thereby driving the second sliders on the outer walls of the two threaded rods to move away from each other, so as to drive the first slider to move in the moving hole, so as to adjust the distance between the grinding rollers to adapt to the grinding process of larger particles; when adjusting the grinding of smaller particle sizes, it is necessary to adjust the grinding flow rate and control the distance between the grinding rollers.

[0025] Working principle: When processing lubricating oil raw materials, place the lubricating oil raw materials into the raw material hopper 51, then start the three motors 13 to work, control their rotation directions and speeds, drive the left and right grinding rollers 2 to rotate towards each other, and then control the right grinding roller 2 to rotate in the opposite direction to the middle grinding roller 2 for grinding, and control the rotation speeds of the three grinding rollers 2. At this time, the lubricating oil raw materials will be driven by the left and right grinding rollers 2 and fall onto them for grinding. At the same time, the compound lubricating oil raw materials will fall onto the right grinding roller 2. According to the requirements of the production process, rotate one side of the threaded rod 8 and drive it through the gear set 55. Use three bevel gears to mesh and drive each other to drive the other threaded rod 8 to rotate, thereby driving the second sliders 10 on the outer walls of the two threaded rods 8 to move away from each other, causing the first slider 4 to move in the movable hole to adjust the distance between the grinding rollers 2 to adapt to the grinding process of larger particles.

At the same time, the bidirectional threaded rod 53 will rotate in the reverse direction, and then the distance between the two adjusting plates 52 will be adjusted and approached, so that the flow rate in the raw material hopper 51 becomes smaller to cooperate with the grinding of the grinding roller 2. At the same time, when the adjusting plates 52 approach each other, the fixed rod 58 will be driven to move, and then the push block 57 and the scraping plate 3 will be driven to move, so that the scraping plate 3 slides on the movable plate 11 through the connecting plate 12 to achieve the purpose of adjustment, thereby reducing the grinding gap on the grinding roller 2 to reduce the flow rate of the lubricating oil raw materials falling onto the grinding roller 2, and thus realizing grinding.

At the same time, the two adjusting rods 610 are used to pull and push the scraping plates 69 on both sides to move closer and farther away, thereby generating a gathering effect to centrally stir and collect the lubricating oil above the material receiving plate 61 and slide it down along the material receiving plate 61, eliminating the need for manual squatting and scraping, improving the work efficiency and reducing the use cost.

[0027] Working principle: The lubricating oil raw materials on the right grinding roller 2 are collected through the material receiving plate 61. When the right grinding roller 2 moves away, the pull rod 64 is pushed to move, so that the grinding roller 2 is always in contact with the bottom of the material receiving plate 61.

At the same time, when the right grinding rollers 2 approach each other, the pull rod 64 is pulled to move, and the round rod 65 is pulled to move. Cooperating with the upward restriction of the pull rod 64 on the round rod 65, the material receiving plate 61 generates a downward deflection angle, so that it is always in contact with the outer wall of the grinding roller 2, and stable material collection is carried out, reducing labor and improving work efficiency. At the same time, when grinding, the rotation of the right grinding roller 2 drives the rotation of the turntable 66 on the back of its rotating shaft, and contacts with the spherical block 68 through a number of grooves opened on it, so that it generates undulations, and drives the L-shaped rod 67 to move. The tooth grooves on its outer wall are engaged with the spur gear 612, so as to drive the forward and reverse rotation of the spur gear 612, and then drive the rotation of the fixed round rod, and drive the cyclic forward and reverse rotation of the elliptical plate 611, so as to push the two dial rods on its outer wall to move, and further make the adjusting rod 610 move, so as to pull the scraper 69 at the other end of it to move, and cooperate with its rotating plate to rotate around the fixed scraper, realizing the function of gathering and collecting the lubricating oil raw materials on the material receiving plate 61, thereby improving work efficiency.
