DETAILED DESCRIPTION

[0017] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0018] like Figures 1 to 4As shown, a high-precision oil injection machine of the present application includes: a cabinet 11, in which an oil tank 12 is arranged, and the oil tank 12 can be used to store oil. A control module 17 is arranged in the cabinet 11, and the control module 17 is electrically connected to the electrical components arranged in the high-precision oil injection machine, so that the high-precision oil injection machine can be controlled to perform high-precision operation and thus achieve high-precision oil injection. Specifically: An oil pump 13 is installed on the cabinet 11, and the oil pump 13 is connected to an oil outlet pipeline 15. The oil outlet pipeline 15 is connected to an oil outlet assembly for discharging oil, so that the oil pump 13 of the oil tank 12 can be discharged to the oil outlet assembly for oil filling through the oil pump 13 and the oil outlet pipeline 15. An oil filling flow sensor 14 is provided in the oil outlet pipeline 15 to detect the amount of oil injected into the target container, so as to achieve accurate oil filling and standardized oil filling amount. A support plate 16 for placing the target container is provided on one side of the cabinet 11, and a lifting assembly 18 is provided under the support plate 16 of the cabinet 11 to lift the support plate 16, so as to drive the target container to move upward to the oil outlet end aligned with the oil outlet pipeline 15.

[0019] The above-mentioned oil outlet assembly includes: a mounting frame 20, on which a plurality of oil outlet cavities 19 are mounted, so as to realize the dispensing of oil into a plurality of target containers. A filling nozzle 21 is provided at the bottom of each oil outlet cavity 19, which is connected to the oil outlet end of the oil outlet pipeline 15 through the filling nozzle 21, so that the oil can be aligned with the bottle mouth of the target container for filling. The top of each oil outlet cavity 19 is provided with an oil inlet hole 191 for connecting the oil outlet pipeline 15. The above-mentioned oil filling flow sensor 14 is arranged in each filling nozzle 21.

[0020] Furthermore, a bubble removal component is provided at the end of the oiling nozzle 21, through which bubbles formed in the oil in the bottle can be removed, so that the gas generated by the impact of the oil in the target container can be vibrated and removed during the oiling process, thereby preventing the air pressure inside the container from being greater than the air pressure outside after packaging, thereby preventing the gas from expanding and opening the package seal when encountering high temperature weather or high temperature storage environment, thereby ensuring the safety of oil packaging. Specifically, the bubble removal component includes: a rubber member 26, the rubber member 26 is installed at the end of the oiling nozzle 21, and the rubber member 26 is provided with an oil outlet 263 for extending into the bottle mouth of the target container. When the rubber member 26 is installed, the oil outlet 263 is connected to the oil outlet hole 211 at the end of the oiling nozzle 21, thereby realizing oil outlet docking, and the rubber member 26 is provided with a sound wave generator 264 in the circumference of the oil outlet 263, and the sound wave generator 264 emits sound waves to the oil in the bottle, thereby vibrating and squeezing the oil, thereby removing bubbles in the oil, and then packaging.

[0021] The rubber member 26 is formed with a through hole 261, and the oil outlet nozzle 263 is inserted into the through hole 261. The upper part of the rubber member 26 is formed with an external thread 262, and is threadedly connected to the inner periphery of the oil injection nozzle 21 through the external thread 262. With such an installation structure, the rubber member 26 can be freely disassembled and replaced and cleaned, which is convenient to use.

[0022] Specifically, the lower end of the oiling nozzle 21 is also provided with a reverse negative pressure chamber 213, the opening of the reverse negative pressure chamber 213 faces the oil outlet 211 of the oiling nozzle 21, and is connected to the drip collection device 23 through the negative pressure pipeline 22. The drip collection device 23 is arranged in the inner cavity formed by the mounting frame 20, and a micro negative pressure pump 34 is arranged on the top thereof. Then, when the oiling is stopped, the negative pressure pump 34 is started at the same time to collect the oil that continues to drip in the oiling pipeline into the drip collection device 23, thereby preventing oil from dripping. The drip collection device 23 is provided with a liquid level detection sensor 24 and an alarm 25. When the detection value of the liquid level detection sensor 24 is greater than the preset value, an alarm is sounded through the alarm 25 to discharge and recover the oil.

[0023] On the basis of the above scheme, a baffle 212 is detachably mounted on the oil outlet end of the oil filling nozzle 21, and the baffle 212 is formed with a cross rubber hole for supplying oil to flow out to the oil filling nozzle 21. The baffle 212 can temporarily block the oil when the negative pressure resistance is too large, thereby further preventing oil from dripping.

[0024] Furthermore, the oil inlet of the oil tank 12 is provided with: a chemical sensor 27 and an optical sensor 28, the chemical sensor 27 is used to detect the chemical composition and impurity content of the oil, and the optical sensor 28 is used to detect the transparency and impurity content of the oil, so that the quality of the oil can be detected in real time through the optical sensor 28 and the chemical sensor 27.

[0025] As an implementation mode of the present scheme, a fuel consumption analysis module is also provided in the control module 17. The fuel consumption analysis module can detect the fuel consumption of the fuel tank 12 and the pipeline during the filling process from the full oil state to the zero oil state of each fuel tank 12, so as to accurately measure the oil packaging loss by integrating the fuel consumption data, thereby accurately calculating the oil packaging volume and avoiding the situation where the oil volume is not calculated clearly.

[0026] Specifically, the high-precision oil injection machine includes: a tank level sensor 29 disposed inside the oil tank 12, an oil inlet flow sensor 30 disposed at the oil inlet end of the oil inlet pipeline of the oil tank 12, and an oil injection flow sensor 14 disposed in the oil injection nozzle 21. The oil consumption analysis module receives the detection data of the tank level sensor 29, the oil inlet flow sensor 30, and the oil injection flow sensor 14, and when the detection value of the tank level sensor 29 reaches a preset value of the zero oil state, calculates the difference between the total flow value of the oil inlet flow sensor 30 and the total flow value of the oil injection flow sensor 14, and the difference is defined as the oil consumption of each oil injection process.

[0027] Furthermore, the control module 17 stores the calculated fuel consumption of each oil injection process, sets the fuel consumption of the first use of the high-precision oil injection machine after each cleaning as the initial fuel consumption, and compares the fuel consumption of each subsequent new oil injection process with the initial fuel consumption, and obtains a first fuel consumption difference between the fuel consumption of each subsequent new oil injection process and the initial fuel consumption. When the first fuel consumption difference is greater than the preset difference, a signal for cleaning the oil tank 12 and each oil pipeline is issued.

[0028] As a more accurate algorithm, based on the above-mentioned fuel consumption calculation process, the control module 17 compares the fuel consumption of each new fuel injection process after the first use of the high-precision oil injection machine after each cleaning with the fuel consumption of the previous fuel injection process, and obtains a second fuel consumption difference between the fuel consumption of each subsequent new fuel injection process and the fuel consumption of the previous fuel injection process. When the number of positive values ​​of the second fuel consumption difference within a unit number is greater than the number of negative values, a signal for cleaning the oil tank 12 and each oil pipeline is issued.

[0029] Through the above-mentioned fuel consumption calculation method, not only the volume used for oil packaging can be accurately determined, but also whether the machine should be cleaned can be determined based on the specific situation of fuel consumption, thereby further improving the efficiency and accuracy of the machine's oiling and ensuring the stable operation of the oiling machine.

[0030] As a specific embodiment, the high-precision oiling machine also includes an oiling nozzle 21 adjustment device. The oiling nozzle 21 adjustment device includes: a connecting frame 31 fixed to the mounting frame 20, and a plurality of driving components 32 are provided on the connecting frame to drive the corresponding oil outlet cavity 19 to move up and down, and the plurality of oil outlet cavities 19 are all slidably installed in the sliding hole 201 of the mounting frame 20, and the upper ends of the plurality of oil chambers are connected to the driving end of the driving component 32. Through such a structural design, the height of the oiling nozzle 21 can be adjusted according to actual conditions to ensure that the distance between the oiling nozzle 21 and the entrance of the target container is within a preset range. In addition, a first slide groove is formed at the lower end of the mounting frame 20, and a sliding connecting plate 33 sliding along a first direction is provided in the first slide groove, and a second slide groove is formed on the sliding connecting plate 33, and the oiling nozzle 21 is slidably connected to the second slide groove along a second direction perpendicular to the first direction. Through such a structure, the position of the oiling nozzle 21 can be adjusted according to the shape and size of different target containers, which is more convenient to use and more versatile. Here, the position of the oiling nozzle 21 can be adjusted manually, or micro screw structures can be respectively arranged in the first slide groove and the second slide groove to realize automatic adjustment of the oiling nozzle 21 through the micro screw structures.
