[0033] The high-precision filling machine comprises an equipment box 1, a weighing component, and at least one conveying component.

[0036] The oil injection assembly includes a support cylinder 17, a third servo motor 16, a lead screw 18, a moving plate 19 and a filling nozzle 22. One end of the support cylinder 17 is fixedly installed on one side wall of the equipment box 1. A sliding groove is formed in the side wall of the support cylinder 17. The lead screw 18 is inserted into the inside of the support cylinder 17, and the end of the lead screw 18 is rotationally connected with the support cylinder 17.

The filling nozzle 22 is slidingly installed on the moving plate 19.

[0037] The filling component is the core part of realizing the filling of lubricating oil, including a detection assembly and an oil injection assembly. The detection assembly is used to accurately measure the height and position of the grease barrel 2, to ensure that the filling nozzle 22 can accurately align with the container port; at the same time, the detection assembly is used to detect the oil level inside the grease barrel 2. The oil injection assembly is used to accurately inject lubricating oil into the container. In the working process, the laser ranging sensor 15 measures the height and position information of the grease barrel 2 in real time by emitting a laser beam and receiving reflected light. These information is transmitted to the control panel, which adjusts the position of the filling nozzle 22 according to the measurement data to ensure that the filling nozzle 22 can accurately align with the feeding port of the grease barrel 2, avoiding the waste of lubricating oil and the pollution of the container.

[0038] When the oil tank 2 reaches the filling position, the control panel controls the third servo motor 16 to drive the moving plate 19 to move according to the measurement data of the laser ranging sensor 15, so that the filling nozzle 22 is accurately aligned with the oil tank 2 inlet. The electric cylinder 20 is fixedly installed on the bottom wall of the moving plate 19, and the output shaft end of the electric cylinder 20 is fixedly connected with the connecting strip 21, and the end of the connecting strip 21 is fixedly installed with the filling nozzle 22. The electric cylinder drives the filling nozzle 22 to move up and down through the connecting strip 21, further ensuring the alignment accuracy of the filling nozzle 22 and the container port.

[0039] The medium outflow end of the oil pump is communicated with the medium inflow end of the filling nozzle 22 through a conduit. After the oil pump is started and the control valve on the filling nozzle 22 is opened, the oil pump extracts the lubricating oil inside the oil tank, and injects the lubricating oil into the oil tank 2 through the filling nozzle 22.

[0040] Specifically, the conveying component includes a first servo motor 6, a first chain, two first square tubes 3, a plurality of first rollers 4, and a plurality of first supporting legs 5.

The first servo motor 6 is fixedly installed on one of the first square tubes 3, and the output shaft end of the first servo motor 6 is fixedly installed with a second sprocket 24, and the second sprocket 24 is located in one of the first square tubes 3. The first chain is wound on the second sprocket 24 and each first sprocket 23, and the first chain is engaged with the second sprocket 24 and each first sprocket 23.

[0041] The conveying component is used to automatically convey the oil tank 2 to the filling position. In the working process, the first servo motor 6 drives each first sprocket 23 to rotate through the second sprocket 24 and the first chain, thereby driving each first roller 4 to rotate synchronously. The oil tank 2 is placed on the plurality of first rollers 4 and automatically moves forward with the rotation of the first rollers 4 to reach the filling position.

[0042] Specifically, the weighing component includes a conveying assembly, a first support plate 8, a weighing sensor 13, a plurality of support blocks 12, and a plurality of second support legs 7.

[0043] The weighing component is a key part of the filling machine, which is used to accurately measure the weight of the oil bucket 2, so as to accurately control the filling amount. In the working process, the oil bucket 2 is placed on the conveying assembly, and the weighing sensor 13 monitors the weight change of the container in real time through the contact of the elastic element with the conveying assembly. When the container reaches the filling position, the weighing sensor 13 transmits the weight signal to the control panel, and the control panel accurately controls the oil injection amount of the filling nozzle 22 according to the preset filling amount and real-time weight data, so as to ensure that the accuracy error of each filling is controlled within a very small range. The conveying assembly is used to transport and move the oil bucket 2. The total weight measured by the weighing sensor 13 minus the weight of the conveying assembly is equal to the weight of the oil bucket 2 and the oil inside it.

The two second square tubes 9 are fixedly installed above the second support plate 25, the second support plate 25 is installed on each support block 12, and the elastic element of the weighing sensor 13 abuts against the lower surface of the second support plate 25.

[0046] The second servo motor 11 drives each second roller 10 to rotate synchronously after the second servo motor 11 is started, each second roller 10 pushes the oil bucket 2 to move, so as to achieve the purpose of conveying and moving the oil bucket 2.

[0047] In the technical solution, the control panel is electrically connected (including communication connection, etc.) with the first servo motor 6, the second servo motor 11, the weighing sensor 13, each laser distance measuring sensor 15, the third servo motor 16, and the electric cylinder 20, so as to meet the purpose of overall automation of the filling machine.
