Description

Technical Field

[0001] This invention relates to the field of filling equipment technology, and in particular to a multi-head lubricating oil filling machine. Background Technology

[0002] The multi-head lubricating oil filling machine is an automated filling device specifically designed for fluid products such as lubricating oil, engine oil, and gear oil. Equipped with 4 to 20 filling heads, it can operate synchronously, completing the filling of multiple containers in a single operation. Compared to single-head filling machines, it significantly improves production efficiency, meeting the needs of large-scale production. Its compact structure and easy maintenance allow for easy integration into existing filling production lines, making it an ideal choice for efficient and accurate filling in the lubricating oil production, automotive maintenance, and petrochemical industries.

[0003] Existing filling machines may experience dripping at the end of the filling tube after filling, resulting in waste and pollution. Summary of the Invention

[0004] To overcome the technical defects of the existing technology, the present invention provides a multi-head lubricating oil filling machine to avoid waste and pollution.

[0005] The technical solution adopted in this invention is:

[0006] A multi-head lubricating oil filling machine includes a filling barrel system, a tail material suction system, a material injection lifting system, a frame, several cutting systems, several injection pipes, and a conveying system. The material injection lifting system is mounted on the frame, and each injection pipe is mounted on the material injection lifting system. Each cutting system is mounted on its corresponding injection pipe. Both the filling barrel system and the material injection lifting system are mounted on the frame. Several cylinder bottom outlet pipes are located on the lower side of the filling barrel system. The tail material suction system includes several retaining rings, a floating device, a sealing plug, a suction piston, and a suction cylinder. The retaining rings are installed inside the cylinder bottom outlet pipes, and the floating devices are located inside the cylinder bottom outlet pipes. The sealing plug is connected to the transmission mechanism. The total buoyancy of the suction piston and the floating device in the lubricating oil is greater than the total weight of the suction piston and the floating device. The sealing plug is suspended at the bottom of the floating device. When the floating device floats, it lifts the sealing plug and seals the retaining ring. The suction piston is installed at the bottom of the sealing plug. The suction cylinder is installed in the cylinder bottom outlet pipe. The suction piston slides along the inside of the suction cylinder. The filling barrel system is connected to an air pump. When the air pump pumps air into the filling barrel system and the disconnecting system is opened, the sealing plug disengages from the retaining ring and moves downward. When the disconnecting system disconnects the injection pipe, the sealing plug rises. The suction cylinder is connected to the bottom of the injection pipe, and the cylinder bottom outlet pipe is connected to the injection pipe.

[0007] Preferably, the filling tank system includes a horizontal tank, an oil inlet pipe, an oil outlet pipe, and a pressurizing air pipe. The horizontal tank is horizontally mounted on the frame, the pressurizing air pipe is mounted on the horizontal tank and connected to an air pump, the oil inlet pipe is mounted on the upper side of the horizontal tank, and the oil outlet pipe is mounted on the lower side of the horizontal tank.

[0008] Preferably, the injection lifting system includes an injection lifting reference frame, an injection lifting slide, an injection lifting cylinder, and an injection synchronization beam. The injection lifting reference frame is mounted on the machine frame, the injection lifting slide is slidably mounted on the injection lifting reference frame, the injection lifting cylinder is mounted on the injection lifting reference frame, the injection lifting cylinder is drivenly connected to the injection lifting slide, the injection synchronization beam is mounted on the injection lifting slide, and each injection pipe is mounted on the injection synchronization beam.

[0009] Preferably, the breaking system includes a breaking cylinder, a breaking piston is installed at the output end of the breaking cylinder, and a breaking step is provided inside the injection pipe. When the breaking piston presses on the breaking step, it blocks the injection pipe.

[0010] Preferably, the conveying system includes two symmetrically arranged guide plates, each guide plate having an opening at both ends, and each guide plate being mounted on a frame.

[0011] Preferably, the top of the snap ring is rounded, and the bottom of the snap ring has a flared opening adapted to the sealing plug.

[0012] Preferably, the buoyancy device is an airbag.

[0013] Preferably, the axes of each of the suction pistons are mounted parallel to each other at the bottom of the sealing plug.

[0014] The beneficial effects of this invention are:

[0015] The material injection lifting system is installed on the frame, and each injection pipe is installed on the material injection lifting system. After the empty oil drum is pushed in from the conveying system, the material injection lifting system drives the injection pipe to descend. When the empty oil drum is pushed in from the conveying system, the material injection lifting system drives the injection pipe to rise to avoid it. The lifting of the material injection lifting system realizes the docking of the injection pipe with the empty oil drum. Each disconnection system is installed on the corresponding injection pipe to realize the disconnection of the injection pipe. Both the filling barrel system and the material injection lifting system are installed on the frame to supply lubricating oil. Several cylinder bottom outlet pipes are provided on the lower side of the filling barrel system, and the lubricating oil flows out from the cylinder bottom outlet pipes.

[0016] The tailings suction system includes several snap-fit ​​rings, a buoyancy device, a sealing plug, a suction piston, and a suction cylinder. The snap-fit ​​rings are installed inside the outlet pipe at the bottom of the cylinder, and the buoyancy device is located inside the outlet pipe at the bottom of the cylinder. The buoyancy device is connected to the sealing plug via a drive mechanism. The total buoyancy of the suction piston and the buoyancy device in the lubricating oil is greater than the total weight of the suction piston and the buoyancy device. The buoyancy of the buoyancy device causes the sealing plug to rise. The sealing plug is suspended at the bottom of the buoyancy device. When the buoyancy device floats up, it lifts the sealing plug, which then seals the snap-fit ​​ring below the snap-fit ​​ring, thus initiating suction. The piston is installed at the bottom of the sealing plug, and the suction cylinder is installed inside the cylinder bottom outlet pipe. The suction piston slides along the inside of the suction cylinder. The filling tank system is connected to an air pump, which is used to accelerate the oil supply. When the air pump pumps air into the filling tank system and the disconnect system is opened, the lubricating oil flows out from the cylinder bottom outlet pipe. Driven by the lubricating oil, the sealing plug in the cylinder bottom outlet pipe disengages from the retaining ring and flows downward, so that the lubricating oil passes through the cylinder bottom outlet pipe in sequence, and then flows through the area between the sealing plug and the retaining ring to the injection pipe to realize the injection.

[0017] When the injection stops, the disconnecting system disconnects the injection pipe, the flow velocity in the cylinder bottom outlet pipe drops to zero, the sealing plug rises, the suction cylinder connects to the bottom of the injection pipe, and the cylinder bottom outlet pipe connects to the injection pipe. The sealing plug rises and then blocks the flow of oil in the cylinder bottom outlet pipe. More importantly, as the suction piston rises, the volume of the suction cylinder decreases, so that the oil in the injection pipe is temporarily drawn into the suction cylinder, avoiding leakage at the bottom of the injection pipe and preventing waste and pollution.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figure 1 — Figure 4 As shown, this embodiment provides a multi-head lubricating oil filling machine, including a filling barrel system 1, a tail material suction system 2, a filling lifting system 3, a frame 4, several cutting systems 5, several filling pipes 6, and a conveying system 7. The filling lifting system 3 is installed on the frame 4, and each filling pipe 6 is installed on the filling lifting system 3. After an empty oil barrel is pushed in from the conveying system 7, the filling lifting system 3 drives the filling pipe 6 to descend. When an empty oil barrel is pushed in from the conveying system 7, the filling lifting system 3 drives the filling pipe 6 to rise to avoid it. The lifting of the filling lifting system 3 realizes the docking of the filling pipe 6 with the empty oil barrel. Each cutting system 5 is installed on the corresponding filling pipe 6 to realize the cutting of the filling pipe 6. Both the filling barrel system 1 and the filling lifting system 3 are installed on the frame 4 to supply lubricating oil. Several cylinder bottom outlet pipes 111 are provided on the lower side of the filling barrel system 1, and the lubricating oil flows out from the cylinder bottom outlet pipes 111.

[0032] The tail material suction system 2 includes several snap-fit ​​rings 21, a buoyancy device 22, a sealing plug 23, a suction piston 24, and a suction cylinder 25. The snap-fit ​​rings 21 are installed inside the cylinder bottom outlet pipe 111. The buoyancy device 22 is located inside the cylinder bottom outlet pipe 111 and is connected to the sealing plug 23. The total buoyancy of the suction piston 24 and the buoyancy device 22 in the lubricating oil is greater than the total weight of the suction piston 24 and the buoyancy device 22. The buoyancy of the buoyancy device 22 drives the sealing plug 23 to rise. The sealing plug 23 is suspended at the bottom of the buoyancy device 22. When the buoyancy device 22 floats, it lifts the sealing plug 23 and seals it under the snap-fit ​​rings 21. The connecting ring 21 and the suction piston 24 are installed at the bottom of the sealing plug 23. The suction cylinder 25 is installed in the cylinder bottom outlet pipe 111. The suction piston 24 slides along the inside of the suction cylinder 25. The filling barrel system 1 is connected to an air pump, which is used to accelerate the oil supply. When the air pump pumps air into the filling barrel system 1 and the disconnect system 5 is opened, the lubricating oil flows out from the cylinder bottom outlet pipe 111. Under the push of the lubricating oil, the sealing plug 23 in the cylinder bottom outlet pipe 111 disengages from the retaining ring 21 and flows downward, so that the lubricating oil passes through the cylinder bottom outlet pipe 111 in sequence, and then flows through the area between the lifting sealing plug 23 and the retaining ring 21 to the injection pipe 6 to realize the injection.

[0033] When the injection stops, the disconnecting system 5 disconnects the injection pipe 6, the flow velocity in the cylinder bottom outlet pipe 111 decreases to zero, the sealing plug 23 rises, the suction cylinder 25 connects to the bottom of the injection pipe 6, and the cylinder bottom outlet pipe 111 connects to the injection pipe 6. The sealing plug 23 rises and thus blocks the flow of oil in the cylinder bottom outlet pipe 111. More importantly, as the suction piston 24 rises, the volume of the suction cylinder 25 decreases, so that the oil in the injection pipe 6 is temporarily drawn into the suction cylinder 25, avoiding leakage at the bottom of the injection pipe 6 and preventing waste and pollution.

[0034] It is worth noting that the oil flow rate of the injection pipe 6 can also be measured separately by a commercially available oil meter, such as the Macnaught brand IM012P-02 flow meter, or the Guoyi brand LSZIMC series meter. When the flow rate recorded by the oil meter reaches the preset value, the PLC controller controls the interruption system 5 of each injection pipe 6 to stop injection. After the injection stops, the oil in the corresponding cylinder bottom outlet pipe 111 stops flowing, causing the buoyancy of the corresponding floating device 22 to drive the sealing plug 23 to rise and suck up the remaining oil in the injection pipe 6 one by one. In other words, the air pump stops pumping air into the filling barrel system 1 only after the last injection pipe 6 stops injection. This can realize the individual control of each injection pipe 6 and fundamentally eliminate injection error.

[0035] Specifically, the filling tank system 1 includes a horizontal tank 11, an oil inlet pipe 12, an oil outlet pipe 13, and a pressurizing air pipe 14. The horizontal tank 11 is horizontally installed on the frame 4, and the pressurizing air pipe 14 is installed on the horizontal tank 11. The pressurizing air pipe 14 is connected to an air pump. When the air pump pumps air into the horizontal tank 11, the bottom outlet pipes 111 of each cylinder are subjected to the same pressure, ensuring that the oil output speed is approximately the same. The oil inlet pipe 12 is installed on the upper side of the horizontal tank 11, and the oil outlet pipe 13 is installed on the lower side of the horizontal tank 11. The oil inlet pipe 12 enables the oil to enter the horizontal tank 11, and the oil outlet pipe 13 discharges the remaining oil after filling is completed.

[0036] Specifically, the injection lifting system 3 includes an injection lifting reference frame 31, an injection lifting slide 32, an injection lifting cylinder 33, and an injection synchronous beam 34. The injection lifting reference frame 31 is mounted on the frame 4. The injection lifting slide 32 is slidably mounted on the injection lifting reference frame 31. The injection lifting cylinder 33 is mounted on the injection lifting reference frame 31 and is connected to the injection lifting slide 32 in a transmission manner. The injection synchronous beam 34 is mounted on the injection lifting slide 32. When the injection lifting cylinder 33 is pushed, each injection pipe 6 is mounted on the injection synchronous beam 34, realizing the synchronous lifting of each injection pipe 6.

[0037] Specifically, the separation system 5 includes a separation cylinder, a separation piston is installed at the output end of the separation cylinder, and a separation step is provided in the injection pipe 6. When the separation piston presses on the separation step, it blocks the injection pipe 6 and interrupts the oil supply when each empty oil tank is full. This segmented structure is existing technology and will not be described in detail here.

[0038] Specifically, the conveying system 7 includes two symmetrically arranged guide plates, each with an opening at both ends. Each guide plate is mounted on the frame 4. Empty oil drums are pushed in side by side on the frame 4. Each guide plate shapes the empty oil drums, so that they are arranged in a row.

[0039] Specifically, the top of the snap ring 21 is rounded, and the bottom of the snap ring 21 is provided with a funnel-shaped opening that matches the sealing plug 23. The purpose of providing a funnel-shaped opening on the lower side of the snap ring 21 is to allow the sealing plug 23 to have sufficient lifting stroke, thereby increasing the volume change of the suction cylinder 25. It is worth noting that due to the funnel-shaped opening, the sealing plug 23 needs more stroke during the process of sealing the funnel-shaped opening, thus increasing the volume change of the suction cylinder 25.

[0040] Specifically, the buoyancy device 22 is an airbag that ensures the buoyancy of the sealing blockage 23.

[0041] Specifically, the axes of each suction piston 24 are installed parallel to each other at the bottom of the sealing plug 23. The suction piston 24 is used not only to suction the residual oil in the injection pipe 6, but also to maintain the posture of the sealing plug 23.

[0042] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention.

All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
