Description

Technical Field

[0001] This utility model relates to a liquid filling machine, specifically a novel petroleum liquid filling machine. Background Technology

[0002] In the field of petroleum liquid filling, traditional filling machines generally suffer from low filling accuracy, poor adaptability, and high safety risks. Existing equipment mostly relies on filling components of fixed height, making it difficult to adapt to containers of different sizes, and is prone to oil spillage and waste due to uncontrollable flow rate during the filling process. In addition, traditional systems have low automation levels, requiring frequent manual intervention to adjust parameters, and cannot meet the needs of rapid switching between multiple batches of oil. To address these shortcomings, this invention provides a novel petroleum liquid filling machine that integrates an intelligent adaptive control system, a high-precision metering module, and a full-process safety protection mechanism. It achieves automatic adjustment of filling height and segmented flow rate control, significantly improving filling efficiency, accuracy, and safety, and is suitable for automated filling operations in high-risk scenarios such as petrochemicals and lubricating oils. Utility Model Content

[0003] To overcome the problems of existing equipment relying on fixed-height filling components, making it difficult to adapt to different container sizes, and the potential for oil spillage and waste due to uncontrollable flow rate during filling, as well as the low automation level of traditional systems requiring frequent manual intervention to adjust parameters and failing to meet the needs of rapid switching between multiple batches of oil, this utility model provides a novel petroleum liquid filling machine that achieves automatic adjustment of filling height and segmented flow rate control, improving filling efficiency, accuracy, and safety.

Fifth counterweight, sixth counterweight, seventh counterweight, eighth counterweight, first transverse moving wheel, moving handle, lower support fixing frame, first fixing nut, regulating valve, rotary bearing, oil pipe connecting rod, regulating valve connector, valve fixing frame, ring-type fixing frame, first connecting sleeve, second transverse moving wheel, second fixing nut, fixing gear, third transverse moving wheel, tension adjustment knob, transverse connecting rod, outer sleeve, second outer sleeve, transverse fixing frame, oil tank, second connecting sleeve, third oil hose, fourth oil hose, fifth oil hose, sixth oil hose, seventh oil hose, eighth oil hose, rotating rotor. The upper, middle, and lower support frames are connected to form an overall support frame. A type-one fixing joint connects to the upper support frame. Upper and lower bracket connectors connect to the upper and middle support frames. The oil tank is connected to the oil tank fixing frame and located inside the upper support frame and above the upper and lower bracket connectors. The upper outlets of the first, second, third, fourth, fifth, sixth, seventh, and eighth oil hoses connect to the oil tank. A type-two fixing joint connects to the upper support frame. The control box connects to the lower support frame. The outer door handle is fixed to the outer door and connected to the lower support frame. The first and second hydraulic oil pumps are connected to the valve fixing frame on top and to the oil pipe fixing clamp on the bottom. The first fixing nut is connected to the rotary bearing and fixed inside the outer and second outer sleeves. The regulating valve connects to the lower outlet of the eighth oil hose. The oil pipe connecting rod is connected to the first fixing nut. The first connecting sleeve is connected to the second transverse moving wheel, the first connecting sleeve is connected to the second hydraulic oil pump, the ring-shaped fixing frame is connected to the transverse connecting rod, the second fixing nut is connected to the transverse fixing frame, the oil tank is connected to the oil tank fixing frame and fixed on the conveyor track device, the moving handle is connected to the lower support fixing frame, the first counterweight base and the second counterweight base are respectively located directly below the first counterweight and the second counterweight, the hydraulic motor rotor is connected to the hydraulic motor and fixed on the transverse fixing frame, the motor is connected to the rotating rotor and fixed on the conveyor track device, and the conveyor track device is fixed on the lower support fixing frame.

[0005] The control box controls the motor to rotate via electrical signals, which in turn drives the rotating rotor to rotate, thereby enabling the conveyor belt device to work and transfer the oil tank fixed to the oil tank mounting bracket.

[0006] The control box controls the hydraulic motor to rotate via electrical signals, which in turn drives the hydraulic pipes to work. This causes the first and second hydraulic oil pumps to operate, drawing oil from the first, second, third, fourth, fifth, sixth, seventh, and eighth oil hoses into the oil tank.

[0007] The control box controls the operation of the regulating valves via electrical signals, thereby controlling the operation of the first hydraulic oil pump and the second hydraulic oil pump, which in turn drives the amount and flow rate of oil output from the first, second, third, fourth, fifth, sixth, seventh, and eighth oil hoses.

[0008] The first, second, and third transverse moving rollers are connected to the first, second, third, fourth, fifth, sixth, seventh, and eighth oil delivery hoses and the rails on the lower support frame, thereby controlling the position of each oil delivery hose.

[0009] The oil flowing into the oil storage tank through the second connecting sleeve then flows out through the upper inlet of the first, second, third, fourth, fifth, sixth, seventh, and eighth oil delivery hoses.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] 1. Significantly improves filling accuracy and flow rate control. By controlling the electrical signals of the control box to regulate the valves and hydraulic oil pump, precise segmented control of the oil output from the oil delivery hose is achieved, solving the problem of oil spillage and waste caused by uncontrollable flow rate in traditional equipment. At the same time, the high-pressure hydraulic oil delivery system ensures a stable filling process and significantly reduces the error range.

[0012] 2. Highly adaptable to different container sizes, enhancing operational flexibility. Equipped with a first, second, and third lateral moving roller, which connects to the oil delivery hose and the lower support frame track, the position and height of the oil delivery hose can be flexibly adjusted. Combined with the conveyor belt device for automatic transport of oil tanks, this effectively solves the problem of traditional equipment relying on fixed-height filling components and being unable to adapt to different container sizes.

[0013] 3. Full-process automated control, reducing manual intervention. The control box uniformly controls the motor, hydraulic motor, and valve switches through electrical signals, realizing automatic transmission of the conveyor belt device, start and stop of the hydraulic oil pump, and regulation of oil flow rate. There is no need for frequent manual parameter adjustments, which significantly improves the degree of automation and meets the production needs of rapid switching between multiple batches of oil products.

[0014] 4. Enhance equipment stability and safety. The overall support frame (upper support frame, middle support frame, and lower support frame) enhances stability through counterweights and fixing frame structures (such as hydraulic rod fixing frames and ring-type fixing frames), reducing shaking during the filling process; the sealing design and precise flow rate control of the oil delivery system can reduce the risk of oil spills, and together with protective structures such as outer doors, improve the safety of filling high-risk petroleum liquids.

[0015] 5. Integrated design improves production efficiency. The parallel design of the oil storage tank and multiple oil delivery hoses enables multi-channel synchronous oil delivery. The high-pressure transmission of the hydraulic oil pump, combined with the continuous operation of the conveyor belt, can significantly shorten the filling time of a single batch. Compared with traditional equipment, the production efficiency is significantly improved, while providing standardized support for the automation of oil production. Attached Figure Description
