Description

Technical Field

[0001] This utility model relates to the field of lubricating oil filling technology, and in particular to a lubricating oil production device for quantitative filling. Background Technology

[0002] In the lubricating oil filling process, a crank mechanism is used as the power unit. This crank mechanism converts rotary motion into reciprocating linear motion through mechanical transmission, providing stable and controllable power output for the filling process. This design is simple and compact, easy to maintain and adjust, and can adapt to different filling requirements. During the filling process, the system uses two one-way valves to achieve directional material delivery: one is an inlet one-way valve, and the other is an outlet one-way valve. When the crank drives the piston outward, a negative pressure is created inside the filling chamber. The inlet one-way valve opens under the pressure difference, and lubricating oil is drawn from the storage tank into the filling chamber through the inlet one-way valve. When the crank drives the piston inward, the pressure inside the filling chamber increases, the outlet one-way valve opens, and the inlet one-way valve closes. The lubricating oil is then precisely delivered to the container to be filled through the outlet one-way valve, thus achieving a stable filling process.

[0003] Although check valves can effectively control the direction of material flow, their operating principle relies on the pressure difference between upstream and downstream components. When dealing with high-viscosity lubricating oil, the high viscous resistance of the fluid significantly affects the establishment of the pressure difference. During piston movement, the flow of high-viscosity lubricating oil lags behind the piston's movement, causing the check valve's opening and closing actions to fail to respond promptly to pressure changes, resulting in a lag. This lag can lead to inaccurate material intake and discharge during filling, affecting filling accuracy and potentially causing problems such as dripping and unstable flow rates. In severe cases, it can reduce production efficiency and affect product quality.

[0004] Based on the above viewpoints, those skilled in the art have provided a lubricating oil production apparatus for quantitative filling. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quantitative filling lubricating oil production device. This device uses a centrifugal discharge mechanism as a unidirectional opening and closing discharge mechanism, eliminating the reliance on pressure difference to achieve the opening and closing effect of the suction function. Instead, the opening and closing function is executed sequentially by the lifting and lowering of the crank slider in the electric crank, avoiding the opening and closing lag caused by the extremely high viscosity of the lubricating oil. Regardless of whether a negative pressure is formed in the piston chamber, the feeding channel can be forcibly opened to ensure stable feeding of high-viscosity materials or under low-pressure conditions.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quantitative filling lubricating oil production device includes a filling base, a piston cylinder mounted on the top of the filling base, and an electric crank fixed to the top of the piston cylinder. A piston rod is fixedly connected to the bottom center of the crank slider of the electric crank, and a piston disc is fixedly connected to the bottom of the piston rod. The piston disc is slidably connected to the inner wall of the piston cylinder. A bottom storage box is fixedly connected to the bottom of the filling base. Pipes are provided on both the left and right side walls of the bottom storage box. A discharge pipe is provided to the right of the right pipe of the bottom storage box, and a centrifugal discharge mechanism is provided to the left of the left pipe of the bottom storage box. Centrifugal discharge mechanisms are provided between the discharge pipe and the right pipe of the bottom storage box, and between the T-shaped feed pipe and the left pipe of the bottom storage box. A drive gear frame for driving the two centrifugal discharge mechanisms is provided at the rear side of the crank slider of the electric crank. A lubricating oil storage cylinder is also fixedly connected to the upper side wall of the filling base. The top opening of the T-shaped feed pipe is connected to the interior of the lubricating oil storage cylinder.

[0008] Preferably, the centrifugal discharge mechanism includes a driven gear, a ratchet gear is provided on the right side of the driven gear, a limit plate is connected to the right side wall of the driven gear by a torsion spring, a number of slots are provided on the right side wall of the ratchet gear, and a centrifugal spring plate is connected to each slot by a spring. The bottom toothed structure of the drive gear frame meshes with two driven gears respectively.

[0009] Preferably, the ratchet in the centrifugal discharge mechanism on the right side has ratchet teeth distributed counterclockwise, and the driven gear in the centrifugal discharge mechanism on the right side is rotatably connected to the outer wall of the pipe on the right side of the bottom storage box. The ratchet in the centrifugal discharge mechanism on the right side is rotatably connected between the pipe on the right side of the bottom storage box and the discharge pipe. The outer wall of the filling base is connected to a filling valve through a pipe, and the filling valve is connected to the interior of the bottom storage box.

[0010] Preferably, the ratchet in the centrifugal discharge mechanism on the left side has ratchet teeth distributed clockwise, and the driven gear in the centrifugal discharge mechanism on the left side is rotatably connected to the outer wall of the T-shaped feed pipe, while the ratchet in the centrifugal discharge mechanism on the left side is rotatably connected between the pipe on the left side of the bottom storage box and the T-shaped feed pipe.

[0011] Preferably, a drive shaft is fixedly connected to the center of the left side wall of the ratchet on the left side, and a drive bevel gear is connected to the other end of the drive shaft. A longitudinal stirring rod is rotatably connected to the center of the inside of the lubricating oil storage cylinder, and a bottom bevel gear is connected to the bottom of the longitudinal stirring rod. The bottom bevel gear meshes with the drive bevel gear.

[0012] Preferably, a horizontal stirring rod is connected to the right side wall of the ratchet on the right side, and the horizontal stirring rod is located inside the pipe on the right side of the bottom storage tank.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the centrifugal discharge mechanism, as a one-way opening and closing discharge mechanism, no longer relies on pressure difference to achieve the opening and closing effect of the suction function. Instead, the opening and closing function is executed sequentially by the lifting and lowering of the crank slider in the electric crank, avoiding the situation of opening and closing lag caused by the extremely high viscosity of the lubricating oil. Regardless of whether the piston chamber forms a negative pressure, the feed channel can be forcibly opened to ensure stable feeding of high-viscosity materials or under low-pressure conditions.

[0015] In this invention, when the ratchet on the left rotates, it drives the drive shaft to rotate, which in turn drives the longitudinal stirring rod to rotate through the meshing relationship between the drive bevel gear and the bottom bevel gear. The rotation of the longitudinal stirring rod stirs the lubricating oil in the lubricating oil storage cylinder, effectively preventing the lubricating oil from separating due to stillness.

[0016] In this invention, when the ratchet on the right side rotates, it will drive the horizontal stirring rod to rotate as well. The horizontal stirring rod ensures that the lubricating oil flowing out smoothly through the pipe on the right side of the bottom storage tank. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Refer to Figures 1-5 This utility model provides an embodiment of a quantitative filling lubricating oil production device, including a filling base 1, a piston cylinder 3 installed on the top of the filling base 1, and an electric crank 5 fixed to the top of the piston cylinder 3. A piston rod 15 is fixedly connected to the bottom center of the crank slider of the electric crank 5, and a piston disc 14 is fixedly connected to the bottom of the piston rod 15. The piston disc 14 is slidably connected to the inner wall of the piston cylinder 3. A bottom storage box 7 is fixedly connected to the bottom of the filling base 1. Pipes are provided on both the left and right side walls of the bottom storage box 7. A discharge pipe 6 is provided on the right side of the right pipe of 7, and a centrifugal discharge mechanism 8 is provided on the left side of the left pipe of the bottom storage box 7. Centrifugal discharge mechanisms 8 are provided between the discharge pipe 6 and the right pipe of the bottom storage box 7, and between the T-shaped feed pipe 9 and the left pipe of the bottom storage box 7. A drive gear 16 for driving the two centrifugal discharge mechanisms 8 to rotate is provided on the rear side of the crank slider of the electric crank 5. A lubricating oil storage cylinder 4 is also fixedly connected to the upper side wall of the filling base 1. The top opening of the T-shaped feed pipe 9 is connected to the inside of the lubricating oil storage cylinder 4. The filling device uses an electric crank 5 to drive the piston disc 14 to lift, thereby drawing out the lubricating oil stored in the lubricating oil storage cylinder 4. At the same time, when the piston disc 14 descends, it can push out the lubricating oil that has been drawn into the bottom storage box 7 and the piston cylinder 3. The centrifugal discharge mechanism 8 is a one-way discharge mechanism that no longer relies on pressure difference to achieve the opening and closing effect of the suction function. Instead, the opening and closing function is executed sequentially by the lifting and lowering of the crank slider in the electric crank 5. This avoids the situation of opening and closing lag caused by the extremely high viscosity of the lubricating oil. Regardless of whether the piston chamber forms a negative pressure, it can force open the feeding channel to ensure stable feeding of high-viscosity materials or under low-pressure conditions.

[0027] The centrifugal discharge mechanism 8 includes a driven gear 81, a ratchet 83 on the right side of the driven gear 81, a limit plate 82 connected to the right side wall of the driven gear 81 by a torsion spring, a number of slots on the right side wall of the ratchet 83, and a centrifugal spring plate 84 connected to each slot by a spring. The bottom toothed structure of the drive gear frame 16 meshes with the two driven gears 81 respectively.

[0028] The ratchet 83 in the centrifugal discharge mechanism 8 on the right side has ratchet teeth distributed counterclockwise, and the driven gear 81 in the centrifugal discharge mechanism 8 on the right side is rotatably connected to the outer wall of the pipe on the right side of the bottom storage box 7. The ratchet 83 in the centrifugal discharge mechanism 8 on the right side is rotatably connected between the pipe on the right side of the bottom storage box 7 and the discharge pipe 6. The outer wall of the filling base 1 is connected to the filling valve 2 through the pipe, and the filling valve 2 is connected to the interior of the bottom storage box 7. When the crank slider of the electric crank 5 rises, the drive gear 16 rises together. At this time, because the ratchet teeth in the right ratchet 83 are distributed counterclockwise, the limiting plate 82 will not drive the ratchet 83 to rotate. When the crank slider of the electric crank 5 falls, the drive gear 16 will drive the driven gear 81 to rotate clockwise. At this time, the limiting plate 82 on the driven gear 81 drives the ratchet 83 to rotate through the ratchet tooth structure on the ratchet 83. Under the action of centrifugal force, the centrifugal spring plate 84 moves outward, causing the right-side feed port to open, and the lubricating oil is discharged from the discharge pipe 6 to the filling valve 2. A horizontal stirring rod 17 is connected to the right side wall of the right ratchet 83. The horizontal stirring rod 17 is located inside the right-side pipe of the bottom storage tank 7. When the right-side ratchet 83 rotates, it will drive the horizontal stirring rod 17 to rotate together. The horizontal stirring rod 17 ensures that the lubricating oil passing through the right-side pipe of the bottom storage tank 7 can flow out smoothly.

[0029] The ratchet 83 in the centrifugal discharge mechanism 8 on the left side has its ratchet teeth distributed clockwise, and the driven gear 81 in the centrifugal discharge mechanism 8 on the left side is rotatably connected to the outer wall of the T-shaped feed pipe 9, while the ratchet 83 in the centrifugal discharge mechanism 8 on the left side is rotatably connected between the left pipe of the bottom storage box 7 and the T-shaped feed pipe 9. When the crank slider of the electric crank 5 rises, the drive gear frame 16 rises together. At this time, since the ratchet teeth in the right ratchet 83 are distributed clockwise, the driven gear 81 rotates, and it drives the ratchet 83 to rotate together through the limiting plate 82. Due to the rotation of the ratchet 83, the centrifugal spring plate 84 on the ratchet 83 opens to the left and right, so that the discharge port opens. The drive shaft 13 is fixedly connected to the center of the left side wall of the left ratchet 83. The other end of the drive shaft 13 is connected to the drive bevel gear 12. The longitudinal stirring rod 10 is rotatably connected to the center of the inside of the lubricating oil storage cylinder 4. The bottom bevel gear 11 is connected to the bottom of the longitudinal stirring rod 10, and the bottom bevel gear 11 meshes with the drive bevel gear 12. When the left ratchet 83 rotates, it will drive the drive shaft 13 to rotate, and then drive the longitudinal stirring rod 10 to rotate through the meshing relationship between the drive bevel gear 12 and the bottom bevel gear 11. The rotation of the longitudinal stirring rod 10 stirs the lubricating oil in the lubricating oil storage cylinder 4, effectively preventing the lubricating oil from separating due to stillness.

[0030] Working principle: This filling device uses an electric crank 5 to drive the piston disc 14 to lift, thereby drawing out the lubricating oil stored in the lubricating oil storage cylinder 4. When the crank slider of the electric crank 5 rises, the drive gear 16 rises together. At this time, because the ratchet teeth in the right ratchet 83 are distributed clockwise, the driven gear 81 rotates, and it drives the ratchet 83 to rotate together through the limiting plate 82. Due to the rotation of the ratchet 83, the centrifugal spring plate 84 on the ratchet 83 opens to the left and right, so that the discharge port opens, thereby drawing out the lubricating oil stored in the lubricating oil storage cylinder 4. When the crank slider of the electric crank 5 descends, the drive gear 16 will drive the driven gear 81 to rotate clockwise. At this time, the limiting plate 82 on the driven gear 81 drives the ratchet 83 to rotate through the ratchet tooth structure on the ratchet 83. Under the action of centrifugal rotation, the centrifugal spring plate 84 moves outward, so that the right-side discharge port opens, and the lubricating oil flows out from the discharge pipe. The 6-way filling valve 2, in which the centrifugal discharge mechanism 8 is a one-way opening and closing discharge mechanism, no longer relies on pressure difference to achieve the opening and closing effect of the suction function. Instead, the opening and closing function is executed sequentially by the lifting and lowering of the crank slider in the electric crank 5, avoiding the opening and closing lag caused by the extremely high viscosity of the lubricating oil. Regardless of whether the piston chamber forms a negative pressure, the feed channel can be forcibly opened to ensure stable feeding of high viscosity materials or low pressure conditions. At the same time, when the ratchet 83 on the left rotates, it will drive the drive shaft 13 to rotate, and then drive the longitudinal stirring rod 10 to rotate through the meshing relationship between the drive bevel gear 12 and the bottom bevel gear 11. The rotation of the longitudinal stirring rod 10 stirs the lubricating oil in the lubricating oil storage cylinder 4, effectively preventing the lubricating oil from stratifying due to stillness. When the ratchet 83 on the right rotates, it will drive the horizontal stirring rod 17 to rotate together. The horizontal stirring rod 17 can ensure that the lubricating oil through the pipe on the right side of the bottom storage tank 7 can flow out smoothly.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
