Description

Technical Field

[0001] This utility model relates to the field of lubricating oil filling technology, and in particular to a lubricating oil filling device with an anti-drip structure. Background Technology

[0002] After the lubricating oil is produced, it needs to be packaged from its bulk state into containers of specific sizes (such as barrels, bottles, cans, etc.) using a filling device. The lubricating oil is packaged into containers of uniform size, which facilitates stacking, storage and logistics transportation and reduces space waste.

[0003] After the current lubricating oil filling equipment is completed, some lubricating oil may remain inside the filling nozzle and stick to the inner wall of the tube. This part of the lubricating oil will drip off due to gravity, which will cause product waste and environmental pollution. It will also contaminate the filling equipment and work surface, resulting in increased cleaning costs.

[0004] Therefore, in response to the problem that residual lubricating oil in the filling nozzle of existing lubricating oil filling devices drips, causing product waste and environmental pollution, a lubricating oil filling device with an anti-drip structure can be designed. By using negative pressure suction, lubricating oil is prevented from remaining inside the filling nozzle tube wall, keeping the working environment clean and tidy, reducing cleaning costs, and thus effectively enhancing the practical value of the device. Utility Model Content

[0005] In order to overcome the problem that after most lubricating oil filling devices have finished filling, some lubricating oil may remain in the filling nozzle and stick to the inner wall of the tube.

A control console is provided at the top of one side of the base, a conveying mechanism is provided between the bases, a support frame is provided at the top of the base, an oil storage tank is provided inside the support frame, a filling pipe is provided at the bottom of the oil storage tank, multiple sets of negative pressure holes are provided on the outer side of the bottom of the filling pipe in a ring shape, an oil collecting assembly is provided on the outer side of the bottom of the filling pipe, a worm gear is provided above the negative pressure hole, the worm gear is rotatably connected to the filling pipe, a scraper is provided on the inner side of the worm gear, and an oil scraping assembly is provided on the outer side of the worm gear.

[0007] Preferably, the conveying mechanism on the control panel on the base transports the oil tank to be filled. The oil storage tank is fixedly supported by the support frame. The oil storage tank stores the lubricating oil to be filled. The lubricating oil in the storage tank is poured into the oil tank through the filling pipe. The oil scraping assembly drives the worm gear to rotate, and the rotation of the worm gear drives the scraper to rotate. The scraper rotates and scrapes off the residual oil by closely adhering to the inner wall of the filling pipe. The negative pressure generated through the negative pressure hole draws the residual oil in the filling pipe into the oil collection assembly. This achieves the effect of avoiding lubricating oil residue in the filling nozzle pipe wall, keeping the working environment clean and tidy, reducing cleaning costs, and enhancing the practical value of the device.

[0008] Preferably, the control console is electrically connected to the conveying mechanism, the negative pressure hole is a through hole inclined downward at a 45° angle, and the scraper rotates close to the inner wall of the filling tube.

[0009] Preferably, the oil collection assembly includes a negative pressure chamber, connecting rods, a negative pressure pipe, and an air pump. A negative pressure chamber is provided on the outer side of the bottom end of the filling pipe. Multiple sets of connecting rods are arranged in a ring at equal intervals on the outer side of the negative pressure chamber. One end of the connecting rod is fixedly connected to the support leg of the support frame. A negative pressure pipe is connected through the outer side of the negative pressure chamber. An air pump is provided on the outer side of the negative pressure pipe. The air pump is electrically connected to the control console.

[0010] Preferably, the oil collection assembly also includes an oil collection tank, an oil drain pipe, and a second solenoid valve. The oil collection tank is located at the top of the base, and the other end of the negative pressure pipe is connected to the oil collection tank. An oil drain pipe is located at the bottom outer side of the oil collection tank, and a second solenoid valve is located on the outer side of the oil drain pipe. The second solenoid valve is electrically connected to the control console.

[0011] Preferably, the oil scraping assembly includes a protective shell and a T-shaped ring block. The protective shell is provided on the outer side of the worm gear and is located above the negative pressure chamber. T-shaped ring blocks are provided at the upper and lower ends of the worm gear. The T-shaped ring block at the top of the worm gear is fitted and rotatably connected to the filling pipe, and the T-shaped ring block at the bottom of the worm gear is fitted and rotatably connected to the top of the negative pressure chamber.

[0012] Preferably, the oil scraping assembly also includes a worm gear and a drive motor. The worm gear is rotatably connected to the inner side of the protective housing and meshes with a worm wheel. The drive motor is provided on the outer side of the protective housing and is electrically connected to the control console. The output end of the drive motor is connected to the worm gear.

[0013] Preferably, an agitator is provided on the inner side of the oil storage tank, an oil inlet pipe is provided at the top of the oil storage tank, a first solenoid valve is provided on the outer side of the oil inlet pipe, the first solenoid valve and the agitator are electrically connected to the control console, and an oil filling valve is provided on the outer side of the filling pipe, the oil filling valve is electrically connected to the control console.

[0014] The beneficial effects of this utility model are:

[0015] During oil filling, the control console on the base controls the conveying mechanism to transport the oil tank to be filled. The support frame fixes and supports the oil storage tank, which stores the lubricating oil to be filled. The conveying mechanism moves the oil tank to be filled to the bottom of the filling pipe. The lubricating oil in the storage tank is poured into the oil tank through the filling pipe. The worm gear rotates to drive the scraper to rotate. The scraper rotates and scrapes off the residual oil close to the inner wall of the filling pipe. The negative pressure hole generates negative pressure to suck up the residual oil in the filling pipe. This solves the problem that after most lubricating oil filling devices are completed, some lubricating oil may still remain in the filling nozzle and stick to the inner wall of the pipe. This part of the lubricating oil will drip off due to gravity, which will cause product waste and environmental pollution. This enhances the practical value of the device.

The support frame 4 is located at the top of the base 1, and the oil storage tank 5 is located inside the support frame 4. The filling pipe 6 is located at the bottom of the oil storage tank 5. Multiple sets of negative pressure holes 7 are arranged in a ring and are equidistantly distributed on the outer side of the bottom end of the filling tube 6. The negative pressure holes 7 are through holes inclined downward at a 45° angle. The negative pressure holes 7 generate negative pressure to suck up the residual oil in the filling tube 6. An oil collection assembly is provided on the outer side of the bottom end of the filling tube 6. A worm gear 8 is provided above the negative pressure holes 7. The worm gear 8 is rotatably connected to the filling tube 6. A scraper 9 is provided on the inner side of the worm gear 8. The scraper 9 rotates close to the inner wall of the filling tube 6. Rotating the worm gear 8 drives the scraper 9 to rotate. The scraper 9 rotates close to the inner wall of the filling tube 6 to scrape off the residual oil. An oil scraping assembly is provided on the outer side of the worm gear 8.

[0023] Please see Figure 1 and Figure 2 In this embodiment, the oil collection assembly includes a negative pressure chamber 701, connecting rods 702, a negative pressure pipe 703, an air pump 704, an oil collection tank 705, an oil drain pipe 706, and a second solenoid valve 707. A negative pressure chamber 701 is located on the outer side of the bottom end of the filling pipe 6. Multiple sets of connecting rods 702 are arranged in a ring at equal intervals on the outer side of the negative pressure chamber 701. One end of each connecting rod 702 is fixedly connected to a leg of the support frame 4. A negative pressure pipe 703 is connected through the outer side of the negative pressure chamber 701. An air pump 704 is located on the outer side of the negative pressure pipe 703 and is electrically connected to the control console 2. An oil collection tank 705 is located at the top of the base 1. The other end of the negative pressure pipe 703 is connected through the oil collection tank 705. An oil drain pipe 706 is located at the bottom outer side of the oil collection tank 705. A second solenoid valve 707 is located on the outer side of the oil drain pipe 706. Solenoid valve 707 is electrically connected to control console 2 and connected to support negative pressure chamber 701 via connecting rod 702. Control console 2 controls air pump 704 to draw in and release air, and controls negative pressure pipe 703 to draw in and release gas. During oil filling, air pump 704 controls negative pressure pipe 703 to send air into negative pressure chamber 701, so that negative pressure hole 7 sends air outward to prevent lubricating oil from entering negative pressure chamber 701 during oil filling. After oil filling, air pump 704 controls negative pressure pipe 703 to draw air into negative pressure chamber 701, so that negative pressure hole 7 generates negative pressure to draw residual oil into negative pressure chamber 701. The residual oil in negative pressure chamber 701 is transported to oil collection tank 705 for unified storage through negative pressure pipe 703. Finally, control console 2 controls second solenoid valve 707 to open and close second solenoid valve 707 to flexibly control oil drain pipe 706 to discharge residual oil stored in oil collection tank 705.

[0024] Please see Figure 3 and Figure 4 In this embodiment, the oil scraping assembly includes a protective housing 801, a T-shaped ring block 802, a worm gear 803, and a drive motor 804. The protective housing 801 is located on the outer side of the worm wheel 8 and is positioned above the negative pressure chamber 701. T-shaped ring blocks 802 are located at both the upper and lower ends of the worm wheel 8. The T-shaped ring block 802 at the top of the worm wheel 8 is rotatably connected to the filling pipe 6, and the T-shaped ring block 802 at the bottom of the worm wheel 8 is rotatably connected to the top of the negative pressure chamber 701. The worm gear 803 is rotatably connected to the inner side of the protective housing 801, and the worm gear 803 meshes with and rotates with the worm wheel 8. Next, a drive motor 804 is installed on the outside of the protective housing 801. The drive motor 804 is electrically connected to the control console 2. The output end of the drive motor 804 is connected to the worm gear 803. The protective housing 801 protects the worm wheel 8 and the worm gear 803 inside. The control console 2 controls the operation of the drive motor 804. The drive motor 804 drives the worm gear 803 to rotate. The rotation of the worm gear 803 drives the worm wheel 8 to mesh and rotate. The rotation of the worm wheel 8 drives the T-shaped ring block 802 to engage and rotate along the filling tube 6 and the negative pressure chamber 701, thereby ensuring that the scraper 9 rotates stably to scrape off the residual oil on the inner wall of the filling tube 6.

[0025] Please see Figure 1 and Figure 2 In this embodiment, an agitator 501 is provided inside the oil storage tank 5, an oil inlet pipe 502 is provided at the top of the oil storage tank 5, and a first solenoid valve 503 is provided outside the oil inlet pipe 502. The first solenoid valve 503 and the agitator 501 are electrically connected to the control console 2. An oil filling valve 601 is provided outside the filling pipe 6 and is electrically connected to the control console 2. The control console 2 controls the agitator 501 to operate, and the agitator 501 agitates the lubricating oil in the oil storage tank 5 to prevent the oil in the oil storage tank 5 from settling. The first solenoid valve 503 flexibly controls the opening and closing of the oil inlet pipe 502, and the oil inlet pipe 502 is used to inject lubricating oil into the oil storage tank 5. The oil filling valve 601 controls the filling pipe 6 to flexibly start the oil filling operation.

[0026] Before filling, the oil storage tank 5 is fixedly supported by the support frame 4. The first solenoid valve 503 is controlled by the control console 2 to open the oil inlet pipe 502, and the lubricating oil is injected into the oil storage tank 5 through the oil inlet pipe 502. At the same time, the stirring mechanism 501 is controlled to stir the lubricating oil in the oil storage tank 5. Then, the conveying mechanism 3 is controlled by the control console 2 on the base 1 to transport the oil tank to be filled and move the oil tank to be filled to the bottom of the filling pipe 6.

[0027] When filling oil, the filling pipe 6 is opened through the filling valve 601, and the lubricating oil in the oil storage tank 5 is filled into the oil tank through the filling pipe 6. At the same time, the control console 2 controls the air pump 704 to send air to the negative pressure chamber 701 through the negative pressure pipe 703, so that the negative pressure hole 7 sends air outward to prevent lubricating oil from entering the negative pressure chamber 701 during filling.

[0028] After filling with oil, the filling valve 601 closes the filling pipe 6. The control console 2 controls the drive motor 804 outside the protective shell 801 to run. The drive motor 804 drives the worm gear 803 to rotate. The rotation of the worm gear 803 drives the worm wheel 8 to mesh and rotate. The rotation of the worm wheel 8 drives the T-shaped ring block 802 to rotate along the filling pipe 6 and the negative pressure chamber 701. The scraper 9 rotates and scrapes off the residual oil close to the inner wall of the filling pipe 6. At the same time, the air pump 704 controls the negative pressure pipe 703 to draw air into the negative pressure chamber 701, so that the negative pressure hole 7 generates negative pressure and draws the residual oil into the negative pressure chamber 701. The residual oil in the negative pressure chamber 701 is transported to the oil collection tank 705 for unified storage through the negative pressure pipe 703. Finally, the control console 2 controls the second solenoid valve 707 to open, and the oil drain pipe 706 is used to drain the residual oil stored in the oil collection tank 705.

[0029] Through the above steps, the control console 2 on the base 1 controls the conveying mechanism 3 to transport the oil tank to be filled. The support frame 4 is used to fix and support the oil storage tank 5, which stores the lubricating oil to be filled. The filling pipe 6 is used to fill the oil tank with the lubricating oil from the storage tank 5. The oil scraping assembly drives the worm gear 8 to rotate, which in turn drives the scraper 9 to rotate. The scraper 9 rotates and scrapes off the residual oil by closely adhering to the inner wall of the filling pipe 6. The negative pressure is generated through the negative pressure hole 7, which draws the residual oil in the filling pipe 6 into the oil collection assembly, thereby preventing lubricating oil from remaining in the wall of the filling nozzle, keeping the working environment clean and tidy, and reducing cleaning costs.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
