Description

Technical Field

[0001] This invention relates to a batching device, specifically a high-precision lubricating oil batching device and its batching method. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. As long as it is applied between two relatively moving objects and can reduce the friction and wear caused by the contact between the two objects, it is called lubricating oil. In the production process of lubricating oil, crude oil and additives need to be put into the inside of the mixing tank and stirred and mixed.

[0003] Existing batching devices typically introduce ingredients into a measuring cylinder for weighing. However, during the weighing process, situations sometimes arise where too much is added and too little is added. This is because if too much is added, some needs to be poured out, and if too little is added, it needs to be added back in. This is inefficient and may not achieve accurate measurement, making it very inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a high-precision lubricating oil dispensing device and its dispensing method to solve the problems encountered in practical use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-precision lubricating oil dispensing device includes a top plate and multiple collecting cylinders evenly arranged on the bottom surface of the top plate. The top of each collecting cylinder is fixedly connected to the top plate, and a measuring cylinder is fixedly connected inside the collecting cylinder. The bottom of each measuring cylinder is fixedly connected to a connecting pipe, and the bottom of the connecting pipe passes through the bottom of the collecting cylinder and is fixedly connected to the top of a vertically arranged discharge pipe. The bottom of the discharge pipe passes through the bottom of the bottom plate and is fixedly connected to the bottom plate. The top of the measuring cylinder is higher than the top surface of the top plate, and an overflow port is opened at the position of the measuring cylinder below the bottom surface of the top plate. A piston that slides vertically is slidably connected inside the measuring cylinder. A discharge port is opened on the piston, and a solenoid valve is fixed inside the discharge port. The top surface of the piston is rotatably connected to the bottom of a vertically arranged lifting rod. A fine-tuning threaded cylinder is slidably connected to the lifting rod, and a fixing frame is threadedly connected to the outer wall of the fine-tuning threaded cylinder. The fixing frame is fixedly connected to the top of the measuring cylinder, and a handle is fixedly connected to the top of the lifting rod.

[0007] In practical use, this invention allows for the adjustment of the piston's position within the measuring cylinder by operating the lifting rod with a handle. This adjustment controls the volume of the portion of the measuring cylinder above the piston. Combined with the overflow port, the amount of lubricating oil added to the measuring cylinder remains constant, while any excess flows directly into the collection cylinder through the overflow port. This design eliminates the need for precise measurement of lubricating oil with a single adjustment, eliminating the need for refilling or adjusting each time lubricating oil is dispensed, thus significantly improving the efficiency of lubricating oil dispensing.

[0008] This invention utilizes a fine-tuning threaded cylinder design. By first raising the piston to its approximate position using a handle, and then rotating the fine-tuning threaded cylinder, the position of the piston can be precisely adjusted, thereby improving the measurement accuracy of lubricating oil and achieving a high-precision effect.

[0009] Preferably, the top and bottom ends of the fine-tuning threaded cylinder are fixedly connected to a limiting plate, and a fixing block is fixedly connected to the top edge of the limiting plate. The fixing block is fixedly connected to one end of the first spring, and the other end of the first spring is fixedly connected to the side of the positioning plate. The positioning plate is slidably connected to the top surface of the limiting plate at the top of the fine-tuning threaded cylinder, and the positioning plate and the lifting rod are provided with matching anti-slip textures on opposite sides, so as to fix the relative position between the lifting rod and the fine-tuning threaded cylinder through the positioning plate.

[0010] Preferably, the bottom end of the collecting cylinder is fixedly connected to a discharge sleeve, which is connected to the recovery cylinder. The ingredients overflowing from the collecting cylinder flow into the recovery cylinder, which facilitates the recovery of excess ingredients. Moreover, when the ingredients in the recovery cylinder reach a certain amount, the ingredients are poured into a measuring cylinder, which can effectively reduce the loss of ingredients.

[0011] Preferably, the top of the recycling cylinder is fixedly connected to a feed pipe, which is inserted into the discharge sleeve. A limiting cylinder is fixedly connected to the outer wall of the bottom end of the feed pipe. The two sides of the limiting cylinder are respectively fixedly connected to one end of a horizontally arranged second spring. The other end of the second spring is fixedly connected to the side of the locking block. The locking block is slidably connected to the top surface of the recycling cylinder, and the locking block is a frame with an opening facing the recycling cylinder. Both sides of the bottom end of the discharge sleeve are fixedly connected to locking seats.

[0012] Preferably, the outer diameter of the feed pipe is the same as the inner diameter of the discharge sleeve.

[0013] In practical use, insert the feed pipe into the discharge sleeve. When inserting, pinch the two locking blocks against the limiting cylinder by hand to compress the second spring until the top of the locking block passes through the locking seat and the top surface of the limiting cylinder touches the bottom surface of the discharge sleeve. At this point, release the locking blocks. Under the action of the second spring, the locking blocks will lock onto the locking seat. When removing the recycling cylinder, pinch the two locking blocks against the limiting cylinder by hand and then pull the recycling cylinder downwards. The operation is simple and convenient.

[0014] Preferably, the inner wall of the discharge sleeve is provided with an installation groove, and a sealing plate is rotatably connected in the installation groove, and a torsion spring is provided at the connection between the sealing plate and the installation groove.

[0015] When the recycling cylinder is pulled out, the sealing plate rotates under the action of the torsion spring, and the other end of the sealing plate rests on the bottom protrusion on the other side of the mounting groove, thereby sealing the discharge sleeve through the sealing plate and realizing the automatic sealing function of the discharge sleeve. This prevents the material from flowing out of the discharge sleeve and causing waste when the recycling cylinder is removed. When the feed pipe is inserted into the discharge sleeve, the sealing plate is pushed open through the feed pipe, and the material automatically flows into the recycling cylinder.

[0016] A method for dispensing high-precision lubricating oil in a dispensing device includes the following steps:

[0017] Step 1: First, pull the lifting rod to adjust the position of the piston in the measuring cylinder. When the piston is adjusted to the approximate position, rotate the fine-tuning screw cylinder to achieve the fine-tuning function of the piston and improve the accuracy of the dispensing device.

[0018] Step 2: After adjustment, pour the lubricating oil into the measuring cylinder from the top until it reaches the overflow port. The excess part will flow into the collection cylinder.

[0019] Step 3: Open the solenoid valve in the discharge port to allow the weighed ingredients in the measuring cylinder to be discharged through the discharge pipe and mixed to achieve the mixing of lubricating oil ingredients. After all the ingredients in the measuring cylinder have been discharged, close the solenoid valve.

[0020] Step 4: The lubricating oil that overflows into the collection cylinder falls into the recovery cylinder. After removing the recovery cylinder, pour the oil back into the measuring cylinder to achieve the recovery of the ingredients.

[0021] Step 5: Repeat steps 2, 3, and 4 to proceed with the next round of ingredient preparation.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] In practical use, this invention only requires one adjustment to quantitatively measure the amount of lubricating oil, eliminating the need to add more or less each time the ingredients are measured, thus greatly improving the efficiency of lubricating oil measurement.

[0024] This invention effectively improves the measurement accuracy of lubricating oil by finely adjusting the threaded cylinder design, achieving a high-precision effect.

[0025] This invention achieves the recycling of ingredients through the design of the recycling cylinder, and is simple and convenient to operate, thus improving the practicality of the batching device. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Please see Figures 1-5In this embodiment of the invention, a high-precision lubricating oil dispensing device includes a top plate 1 and a plurality of collecting cylinders 5 evenly arranged on the bottom surface of the top plate 1. The top end of each collecting cylinder 5 is fixedly connected to the top plate 1. A measuring cylinder 7 is fixedly connected inside the collecting cylinder 5. A connecting pipe 6 is fixedly connected to the bottom end of each measuring cylinder 7. The bottom end of each connecting pipe 6 passes through the bottom of the collecting cylinder 5 and is fixedly connected to the top end of a vertically arranged discharge pipe 4. The bottom end of the discharge pipe 4 passes through the bottom of the bottom plate 3 and is fixedly connected to the bottom plate 3. The top end of the measuring cylinder 7 is higher than the top surface of the top plate 1. The measuring cylinder 7 has an overflow port located below the bottom surface of the top plate 1. The measuring cylinder 7 has a piston 8 that slides vertically inside. The piston 8 has a discharge port 9, and a solenoid valve is fixed inside the discharge port 9. The top surface of the piston 8 is rotatably connected to the bottom end of the vertically arranged lifting rod 10. A fine-tuning threaded cylinder 11 is slidably connected to the lifting rod 10, and a fixing frame 12 is threadedly connected to the outer wall of the fine-tuning threaded cylinder 11. The fixing frame 12 is fixedly connected to the top of the measuring cylinder 7, and a handle 13 is fixedly connected to the top of the lifting rod 10.

[0034] It should be noted that in actual use, the lifting rod 10 is operated by the handle 13 to adjust the position of the piston 8 inside the measuring cylinder 7. By adjusting the position of the piston 8, the volume of the portion of the measuring cylinder 7 above the piston 8 is adjusted. With the addition of the overflow port, the amount of material in the measuring cylinder 7 is fixed each time lubricating oil is added, while the excess flows directly into the collecting cylinder 5 through the overflow port. Through this design, the amount of lubricating oil can be quantitatively measured with only one adjustment, eliminating the need to add more or less each time the material is measured, thus greatly improving the efficiency of lubricating oil measurement.

[0035] It should also be noted that, through the design of the fine-tuning threaded cylinder 11, the piston 8 is first raised to an approximate position by the handle 13, and then the position of the piston 8 can be finely adjusted by rotating the fine-tuning threaded cylinder 11, thereby improving the measurement accuracy of lubricating oil and achieving a high-precision effect.

[0036] The top and bottom ends of the fine-tuning threaded cylinder 11 are fixedly connected to a limiting plate 14. A fixing block 15 is fixedly connected to the top edge of the limiting plate 14. The fixing block 15 is fixedly connected to one end of the first spring 16. The other end of the first spring 16 is fixedly connected to the side of the positioning plate 17. The positioning plate 17 is slidably connected to the top surface of the limiting plate 14 at the top of the fine-tuning threaded cylinder 11. The positioning plate 17 and the lifting rod 10 are provided with matching anti-slip textures on opposite sides, so that the relative position between the lifting rod 10 and the fine-tuning threaded cylinder 11 is fixed by the positioning plate 17.

[0037] The bottom end of the collecting cylinder 5 is fixedly connected to the discharge sleeve 23, which is connected to the recovery cylinder 2. The ingredients overflowing from the collecting cylinder 5 flow into the recovery cylinder 2, which facilitates the recovery of excess ingredients. Moreover, when the ingredients in the recovery cylinder 2 reach a certain amount, the ingredients are poured into the measuring cylinder 7, which can effectively reduce the loss of ingredients.

[0038] The top of the recycling cylinder 2 is fixedly connected to a feed pipe 21, which is inserted into the discharge sleeve 23. A limiting cylinder 19 is fixedly connected to the outer wall of the bottom end of the feed pipe 21. The two sides of the limiting cylinder 19 are fixedly connected to one end of a horizontally arranged second spring 20, and the other end of the second spring 20 is fixedly connected to the side of a locking block 18. The locking block 18 is slidably connected to the top surface of the recycling cylinder 2, and the locking block 18 is a frame with an opening facing the recycling cylinder 2. Both sides of the bottom end of the discharge sleeve 23 are fixedly connected to locking seats 22.

[0039] The outer diameter of the feed pipe 21 is the same as the inner diameter of the discharge sleeve 23.

[0040] In actual use, the feed pipe 21 is inserted into the discharge sleeve 23. When inserting, the two locking blocks 18 are pinched towards the limiting cylinder 19 by hand, so that the second spring 20 is in a compressed state until the top of the locking block 18 passes through the locking seat 22 and the top surface of the limiting cylinder 19 touches the bottom surface of the discharge sleeve 23. At this time, the locking block 18 is released, and under the action of the second spring 20, the locking block 18 is locked on the locking seat 22. When taking out the recycling cylinder 2, the two locking blocks 18 are pinched towards the limiting cylinder 19 by hand, and then the recycling cylinder 2 is pulled out downwards. The operation is simple and convenient.

[0041] The inner wall of the discharge sleeve 23 is provided with an installation groove 25, and a sealing plate 24 is rotatably connected in the installation groove 25. A torsion spring is provided at the connection between the sealing plate 24 and the installation groove 25.

[0042] It should be noted that when the recycling cylinder 2 is pulled out, the sealing plate 24 rotates under the action of the torsion spring, and the other end of the sealing plate 24 rests on the bottom protrusion on the other side of the mounting groove 25, thereby sealing the discharge sleeve 23 through the sealing plate 24, realizing the automatic sealing function of the discharge sleeve 23, and avoiding the waste caused by the material flowing out from the discharge sleeve 23 when the recycling cylinder 2 is taken out. When the feed pipe 21 is inserted into the discharge sleeve 23, the sealing plate 24 is pushed open through the feed pipe 21, and the material automatically flows into the recycling cylinder 2.

[0043] A method for dispensing high-precision lubricating oil in a dispensing device includes the following steps:

[0044] Step 1: First, pull the lifting rod 10 by the handle 13 to adjust the position of the piston 8 in the measuring cylinder 7. When the piston 8 is adjusted to the approximate position, rotate the fine-tuning screw cylinder 11 to realize the fine-tuning function of the piston 8 and improve the accuracy of the dispensing device.

[0045] Step 2: After the adjustment is completed, pour the lubricating oil into the measuring cylinder 7 from the top until it reaches the overflow port. The excess part flows into the collecting cylinder 5.

[0046] Step 3: Open the solenoid valve in the discharge port 9 to allow the weighed ingredients in the measuring cylinder 7 to be discharged through the discharge pipe 4 and mixed to achieve the mixing of lubricating oil ingredients. After all the ingredients in the measuring cylinder 7 have been discharged, close the solenoid valve.

[0047] Step 4: The lubricating oil that overflows into the collection cylinder 5 falls into the recovery cylinder 2. After removing the recovery cylinder 2, pour it back into the measuring cylinder 7 to realize the recovery of the ingredients.

[0048] Step 5: Repeat steps 2, 3, and 4 to proceed with the next round of ingredient preparation.

[0049] Although the present invention 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 invention should be included within the protection scope of the present invention.
