Description

Technical Field

[0001] The invention relates to the technical field of lubricating oil raw material grinding, and in particular to a raw material grinding device for lubricating oil production. Background Art

[0002] Grease is a lubricant used to reduce friction, wear and heat. Grease is a thick, oily semi-solid and is used in the friction parts of machinery to lubricate and seal. It is also used on metal surfaces to fill gaps and prevent rust. In the production process of lubricants, the lubricant raw materials usually need to undergo strict screening and processing to ensure the quality and purity of the lubricants.

[0003] The prior art lubricating oil raw material grinding device, such as the Chinese patent application document with publication number CN118744029A, discloses a raw material grinding device for lubricating oil production, comprising: a workbench, the inner wall of the workbench is provided with three groups of grinding rollers, each of the grinding rollers is provided with a scraper plate above, the tops of the two left grinding rollers are provided with an adjustment mechanism for adjusting the grinding amount, and one side of the right grinding roller is provided with a material collecting mechanism for collecting the ground lubricating oil, three movable holes are respectively opened on both sides of the inner wall of the workbench, the inner wall of each movable hole is slidably connected to a first slider, and the two ends of the grinding roller are respectively connected to the first slider by a rotating shaft. The cam is provided with a plurality of sliding holes on the upper and lower sides of the movable hole, and a fixed block is fixedly connected to the sliding hole. One side of each of the fixed blocks is rotatably connected to a threaded rod through a bearing. The outer wall of the threaded rod is threadedly connected to a second slider, and the second slider is slidably connected to the sliding hole. The front side of the second slider is connected to a mounting plate by bolts. The front side of the mounting plate is fixedly connected to a motor, and the output end of the motor movably passes through the mounting plate and is fixedly connected to the extending end of the rotating shaft. The top of the mounting plate is fixedly connected to a movable plate, and the top of the movable plate is connected to the top of the scraper plate on the left side through a connecting plate.

[0004] When the above-mentioned prior art processes the lubricating oil raw material, the lubricating oil raw material is placed in the raw material bucket, and then the three motors are started to work, and their direction and speed are controlled to drive the left and right grinding rollers to rotate in opposite directions, and then the grinding roller on the right is controlled to rotate in the opposite direction to the middle grinding roller, so as to grind the lubricating oil raw material and control the speed of the three grinding rollers. At this time, the lubricating oil raw material will be driven by the left and right grinding rollers and fall on them for grinding. At the same time, the composite lubricating oil raw material falls on the right grinding roller. According to the requirements of the production process, the rotation of the threaded rod on one side is adjusted and transmitted through the gear set. The three bevel gears are meshed with each other to drive the other threaded rod to rotate, and then the second sliders on the outer walls of the two threaded rods are driven away from each other to drive the first slider to move in the movable hole, so as to adjust the spacing between the grinding rollers to adapt to the grinding process of larger particles; when adjusting the grinding of smaller particles, it is necessary to adjust the grinding flow and control the spacing between the grinding rollers. At this time, it is necessary to flip the threaded rod to adjust the distance between the left and right grinding rollers and the middle grinding roller.

[0005] However, the above-mentioned prior art still has the following shortcomings: the lubricating oil raw material is a thick, greasy semi-solid. In order to limit the lubricating oil raw material in the axial direction of the grinding roller, a baffle is generally installed on the grinding device, and the baffle is made to contact the grinding roller. When the lubricating oil raw material is put into the raw material hopper, due to the fluidity of the lubricating oil, the lubricating oil raw material is easy to enter between the baffle and the grinding roller, and remain on the contact surface of the baffle and the grinding roller and cannot be ground. The lubricating oil raw material remaining on the contact surface of the baffle and the grinding roller is easily contaminated by impurities when it stays in the air for a long time, thereby easily causing pollution to the subsequent lubricating oil raw materials.

[0039] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figures 1 to 9 As shown, the raw material grinding device for lubricating oil production of the present invention comprises a grinding mechanism 1, an adjusting mechanism 2, a blocking mechanism 3 and an auxiliary mechanism 4. The grinding mechanism 1 comprises a grinding roller 12 and a discharge hopper 13. The grinding rollers 12 are provided in three numbers. The lubricating oil raw material can be ground by the three grinding rollers 12. The discharge hopper 13 is provided between two adjacent grinding rollers 12 and is used to discharge the lubricating oil raw material. The adjusting mechanism 2 is connected to the grinding mechanism 1 and is used to adjust the spacing between the three grinding rollers 12, so as to adjust the grinding accuracy of the lubricating oil raw material. The blocking mechanism 3 is connected to the grinding mechanism 1. The blocking mechanism 3 is provided in two numbers. The two blocking mechanisms 3 are respectively located at the two ends of the bottom of the discharge hopper 13, so as to be able to discharge the lubricating oil raw material in the discharge hopper 13. When the oil raw material is discharged, the lubricating oil raw material is limited and blocked in the axial direction of the grinding roller 12, and at the same time, the lubricating oil raw material on the contact surface of the blocking mechanism 3 and the grinding roller 12 can be pushed toward the middle position of the grinding roller 12 to avoid the contamination of the subsequent lubricating oil raw material due to the contamination of the lubricating oil raw material on the contact surface of the blocking mechanism 3 and the grinding roller 12 after being retained for a long time. The auxiliary mechanism 4 is connected in the discharge hopper 13, and the auxiliary mechanism 4 is connected to the blocking mechanism 3. When the blocking mechanism 3 is running, it can drive the auxiliary mechanism 4, so that the auxiliary mechanism 4 can intermittently discharge the lubricating oil raw material in the discharge hopper 13 to avoid excessive accumulation of lubricating oil raw material between the two grinding rollers 12 below the discharge hopper 13, thereby improving the grinding efficiency of the lubricating oil raw material.

[0041] The lubricating oil raw material is put into the discharge hopper 13 on the grinding mechanism 1, and the lubricating oil raw material is transported to the two grinding rollers 12 below it through the discharge hopper 13, and the three grinding rollers 12 on the grinding mechanism 1 are started to rotate, and the lubricating oil raw material is ground by the three grinding rollers 12. During the discharge process of the discharge hopper 13, the lubricating oil raw material in the discharge hopper 13 is intermittently discharged by the auxiliary mechanism 4 to avoid blockage caused by excessive accumulation of lubricating oil raw material between the two grinding rollers 12 and reduce the grinding efficiency. When the lubricating oil raw material leaves the discharge hopper 13 and enters between the two grinding rollers 12 below it, the lubricating oil raw material is limited and blocked in the axial direction of the grinding rollers 12 by two blocking mechanisms 3, and the lubricating oil raw material on the contact surface of the blocking mechanism 3 and the grinding roller 12 is pushed out, so that the lubricating oil raw material on the contact surface is ground together with other lubricating oil raw materials, and the lubricating oil raw material on the contact surface of the blocking mechanism 3 and the grinding roller 12 is prevented from being contaminated after being contaminated for a long time and causing contamination to the subsequent lubricating oil raw materials.

[0042] like Figure 1 and Figure 2 As shown, the grinding mechanism 1 also includes a frame 11 and a discharge channel 14. The three grinding rollers 12 are rotatably connected to the frame 11. A driving member is connected inside the frame 11 (the driving member is a prior art and is not shown in the figure). The driving member can drive the three grinding rollers 12 to rotate, thereby grinding the lubricating oil raw material. A discharge hopper 13 is connected to the frame 11. The discharge hopper 13 is located above two of the grinding rollers 12. The two blocking mechanisms 3 are located at the bottom of the discharge hopper 13 and are respectively close to the two ends of the two grinding rollers 12. The discharge channel 14 is connected to the frame 11 for discharging the ground lubricating oil raw material.

[0043] like Figures 1 to 6As shown, the blocking mechanism 3 includes a telescopic portion 31, a lifting portion 32, a support portion 33, a transverse portion 34, a baffle 35, a slope 4 351, an elastic portion 1 36 and an elastic portion 2 37. The support portion 33 is connected to the frame 11, the telescopic portion 31 is connected in the frame 11, the telescopic portion 31 is an electric telescopic rod, the lifting portion 32 is connected to the telescopic end of the telescopic portion 31, the lifting portion 32 is provided with a slope 1 321, the transverse portion 34 is limitedly slidably connected to the bottom of the support portion 33, and the transverse portion 34 is provided with a slope 2 341. When the lifting portion 32 moves downward, the slope 1 321 thereon can squeeze the slope 2 341 on the transverse portion 34, so that the transverse portion 34 moves toward the direction close to the baffle 35. The side of the transverse portion 34 close to the baffle 35 is provided with a slope 342, and the baffle 35 is limitedly slidably connected to the support portion 33 close to the grinding roller 12 The side of the position of the part is used to limit and block the lubricating oil raw material. The baffle plate 35 is provided with a slope four 351. When the transverse moving part 34 moves, it can squeeze the slope four 351 on the baffle plate 35 through its slope three 342 to move the baffle plate 35 upward, and at the same time, the lubricating oil raw material on the contact surface of the baffle plate 35 and the grinding roller 12 is scraped off and pushed out, so that the lubricating oil raw material on the contact surface of the grinding roller 12 is ground together with other lubricating oil raw materials, so as to avoid the contamination of subsequent lubricating oil raw materials due to the contamination of the lubricating oil raw material on the surface of the baffle plate 35 close to the grinding roller 12 after being contaminated for a long time. The elastic part 1 36 and the elastic part 2 37 are both compression springs. The elastic part 1 36 is connected between the transverse moving part 34 and the supporting part 33, and is used to drive the transverse moving part 34 to reset. The elastic part 2 37 is connected between the baffle plate 35 and the supporting part 33, and is used to drive the baffle plate 35 to reset.

[0044] Start the telescopic part 31 to drive the lifting part 32 to move downward. When the lifting part 32 moves downward, the inclined surface 1 321 thereof squeezes the inclined surface 2 341 on the transverse moving part 34, so that the transverse moving part 34 moves toward the direction close to the baffle 35 and squeezes the elastic part 1 36. When the transverse moving part 34 moves, the inclined surface 342 thereof squeezes the inclined surface 4 351 on the baffle 35, so that the baffle 35 moves upward and squeezes the elastic part 2 37, and at the same time, the lubricating oil raw material on the contact surface between the baffle 35 and the grinding roller 12 is scraped off and pushed out, and the scraped lubricating oil raw material is ground together with other lubricating oil raw materials.

[0045] When the telescopic part 31 is started to drive the lifting part 32 to move upward, the elastic part 1 36 pushes the transverse part 34 to move in a direction away from the baffle 35, and at the same time, the elastic part 2 37 pushes the baffle 35 to move downward, and the baffle 35 scrapes off the lubricating oil material attached to the inclined surface 3 342 of the transverse part 34.

[0046] like Figures 3 to 9As shown, the auxiliary mechanism 4 includes a rotating shaft 41, a gear 42, a tooth plate 43, a rotating part 44, a fixing ring 45, a cutter 46 and an elastic part 47. The rotating part 44 is arranged in the discharge hopper 13, the rotating shaft 41 is connected to the end of the rotating part 44, and the rotating shaft 41 passes through the discharge hopper 13. The rotating part 44 is rotatably connected to the discharge hopper 13 through the rotating shaft 41. The cross section of the rotating part 44 is elliptical. When the rotating part 44 is in a horizontal state, the discharge port at the bottom of the discharge hopper 13 can be blocked. The gear 42 is connected to one end of the rotating shaft 41 that passes through the discharge hopper 13. The tooth plate 43 is connected to the lifting part 32, and the tooth plate 43 is meshed with the gear 42. When the lifting part 32 moves downward, it meshes with the gear 42 for transmission, and the rotating part 44 is driven by the rotating shaft 41 to rotate, so that the rotating part 44 changes from a horizontal state to an inclined state, thereby opening the discharge port at the bottom of the discharge hopper 13, and the lubricating oil raw material inside the discharge hopper 13 is discharged from the discharge port. Through the up and down reciprocating movement of the lifting part 32, the rotating part 44 can switch back and forth between the horizontal state and the inclined state, so as to achieve the purpose of intermittent discharge of the lubricating oil raw material in the discharge hopper 13, avoid excessive accumulation of lubricating oil raw material between the two grinding rollers 12 below the discharge hopper 13, and improve the grinding efficiency of the lubricating oil raw material.

[0047] The fixing ring 45 is connected to the top of the baffle 35, and the fixing ring 45 is sleeved on the outside of the rotating shaft 41. The fixing ring 45 is not coaxial with the rotating shaft 41. The cutter 46 is inserted at the bottom of the rotating part 44. The top of the fixing ring 45 contacts the lower end of the cutter 46. The elastic part three 47 is a compression spring. The elastic part three 47 is connected between the cutter 46 and the rotating part 44, and is used to drive the cutter 46 to reset.

[0048] When the baffle 35 moves upward, it drives the fixed ring 45 upward, so that the fixed ring 45 pushes the cutter 46 to move in the direction of extending into the rotating part 44, and compresses the elastic part three 47 until the axis of the fixed ring 45 coincides with the axis of the rotating part 44, and at this time the rotating part 44 rotates from a horizontal state to an inclined state, and drives the cutter 46 to rotate, and makes the cutter 46 move on the outside of the fixed ring 45. When the baffle 35 moves downward, it drives the fixed ring 45 downward. At this time, the elastic part three 47 pushes the cutter 46 to move in the direction of extending out of the rotating part 44, and the rotating part 44 rotates from an inclined state to a horizontal state. It can be seen that through the up and down reciprocating movement of the baffle 35, the cutter 46 can be driven to reciprocate in the rotating part 44, thereby continuously cutting the lubricating oil raw material to enhance the subsequent grinding effect of the lubricating oil raw material.

[0049] Working principle:

[0050] The lubricating oil raw material is put into the discharge hopper 13 on the grinding mechanism 1, and the discharge hopper 13 transports the lubricating oil raw material to between the two grinding rollers 12 below it. At the same time, the driving member is started to drive the three grinding rollers 12 to grind the lubricating oil raw material, and the baffles 35 on the two blocking mechanisms 3 limit the lubricating oil raw material in the axial direction of the grinding roller 12.

[0051] Start the telescopic part 31 to drive the lifting part 32 to move up and down reciprocatingly. When the lifting part 32 moves downward, the inclined surface 1 321 thereon squeezes the inclined surface 2 341 on the transverse moving part 34, so that the transverse moving part 34 moves toward the direction close to the baffle 35 and squeezes the elastic part 1 36. When the transverse moving part 34 moves, the inclined surface 342 thereon squeezes the inclined surface 4 351 on the baffle 35, so that the baffle 35 moves upward and squeezes the elastic part 2 37, and at the same time, the lubricating oil raw material on the contact surface between the baffle 35 and the grinding roller 12 is scraped off and pushed out, so that the scraped lubricating oil raw material is ground together with other lubricating oil raw materials. When the lifting part 32 moves upward, the elastic part 1 36 pushes the transverse moving part 34 to move in the direction away from the baffle 35, and at the same time, the elastic part 2 37 pushes the baffle 35 to move downward, and the baffle 35 scrapes off the lubricating oil raw material attached to the inclined surface 3 342 of the transverse moving part 34.

[0052] When the baffle 35 moves upward, it drives the fixed ring 45 upward, so that the fixed ring 45 pushes the cutter 46 to move in the direction of extending into the rotating part 44, and compresses the elastic part three 47 until the axis of the fixed ring 45 coincides with the axis of the rotating part 44, and at this time the rotating part 44 rotates from the horizontal state to the inclined state, and drives the cutter 46 to rotate, and makes the cutter 46 move on the outside of the fixed ring 45. When the baffle 35 moves downward, it drives the fixed ring 45 downward. At this time, the elastic part three 47 pushes the cutter 46 to move in the direction of extending out of the rotating part 44, and the rotating part 44 rotates from the inclined state to the horizontal state. The up and down reciprocating movement of the baffle 35 drives the cutter 46 to reciprocate in the rotating part 44, thereby continuously cutting the lubricating oil raw material. At the same time, the rotating part 44 continuously switches between the horizontal state and the inclined state, so as to realize intermittent discharge of the lubricating oil raw material in the discharge hopper 13.

[0053] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
