A guide groove is opened in the middle position of the inner cavity of the valve core 901. Three guide grooves 902 which are connected to the guide groove are opened on the circumferential outer wall of the valve core 901. The size of the guide groove is adapted to the feed pipe 401, the discharge pipe 402 and the delivery pipe 403.

[0039] like Figure 1 and Figure 2 and Figure 3 and Figure 4 Then, the cylinder 1001 drives the piston to move toward the direction close to the deflector 4. The movement of the piston will push the lubricating oil in the cylinder 7 into the discharge pipe 402, and enter the discharge nozzle 6 through the discharge pipe 402 to realize the filling function.

[0040] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The discharge nozzle 6 is provided with a valve for controlling the on-off of the pipeline, which is opened only when the piston moves toward the direction of the guide device 4, so that the pipeline of the discharge nozzle 6 is unobstructed, so that the lubricating oil can enter the discharge nozzle 6 and overflow through the discharge nozzle 6 to achieve infusion.

[0041] like Figure 1 and Figure 2 and Figure 6 The inner cavity of the feed hopper 5 is hollow and has an opening at the top. A connecting pipe 11 for feeding is integrated on the outer circumferential wall of the feed hopper 5. The connecting pipe 11 is connected to the discharge port of the feed pump through a pipeline. The feed pump provides power, and the produced lubricating oil enters the inner cavity of the feed hopper 5 through the connecting pipe 11 for easy filling.

[0042] like Figure 1 and Figure 2 and Figure 5 and Figure 6 and Figure 7 In order to cool down the high-temperature lubricating oil after production to reduce the possibility of oxidation of the lubricating oil due to excessive temperature, a cooling component 12 for cooling the lubricating oil in the feeding hopper 5 is provided on the feeding hopper 5.

[0043] like Figure 1 and Figure 2 and Figure 5 and Figure 6 and Figure 7The cooling assembly 12 includes a sealing cover 1201 which is nested on the feed hopper 5 and closes the top opening of the feed hopper 5. The sealing cover 1201 is detachably fixedly connected to the feed hopper 5. The inner cavity of the sealing cover 1201 is hollow and the top is open. A plurality of cooling pipes 1202 located in the feed hopper 5 are fixed on the lower surface of the sealing cover 1201. The plurality of cooling pipes 1202 are evenly arranged. The inner cavity of the cooling pipe 1202 is hollow and the bottom is closed. The top is connected to the inner cavity of the sealing cover 1201. The inner cavity of the sealing cover 1201 is provided with a serpentine cold water pipe 1203, and the cold water pipe 1203 enters the plurality of cooling pipes 1202 in sequence. The cold water pipe 1203 is fixedly connected to the bottom of the inner groove of the sealing cover 1201 and the inner groove wall of the cooling pipe 1202 in a detachable manner through a pipe clamp. An inspection cover 1204 threadedly connected to the sealing cover 1201 is nested on the top of the sealing cover 1201. The inspection cover 1204 closes the top opening of the sealing cover 1201. Two circular holes are provided on the inspection cover 1204. The water inlet end 1205 and the water outlet end 1206 of the cold water pipe 1203 both pass through the inspection cover 1204 through the circular holes and are tightly connected to the inspection cover 1204.

[0044] like Figure 1 and Figure 2 A cold water tank 1207 and a water supply pump 1208 are provided on the side of the bracket 2. The water outlet of the cold water tank 1207 is connected to the water inlet of the water supply pump 1208 through a pipeline, the water outlet of the water supply pump 1208 is connected to the water inlet end 1205 of the cold water pipe 1203 through a pipeline, and the water outlet end 1206 of the cold water pipe 1203 is connected to the water inlet of the cold water tank 1207 through a pipeline.

[0045] like Figure 1 and Figure 2 , powered by a water supply pump 1208, cold water in the cold water tank 1207 enters the cold water pipe 1203, the serpentine cold water pipe 1203 is coiled around the bottom of the inner cavity groove of the sealing cover 1201, and enters and passes through a number of evenly arranged cooling pipes 1202 in turn, and the cold water passing through the cold water pipe 1203 flows back to the cold water tank 1207. By setting up a number of cooling pipes 1202, the contact area between the lubricating oil and the cooling pipe 1202 is increased, thereby improving the cooling efficiency. The sealing cover 1201 and the supply hopper 5 are detachably fixedly connected, which is convenient for the disassembly and assembly of the sealing cover 1201, and the inspection cover 1204 is detachably fixedly connected to the sealing cover 1201, which is convenient for the disassembly and assembly of the inspection cover 1204, thereby facilitating the replacement and maintenance of the cold water pipe 1203 and increasing the service life of the device.

[0046] like Figure 1 and Figure 2 The cold water tank 1207 is provided with a plurality of fans for cooling the cold water in the cold water tank 1207 , the cold water tank 1207 is provided with a temperature sensor for detecting the temperature of the cold water, and a plurality of evenly arranged heat sinks are fixed on the outer wall of the cold water tank 1207 .

[0047] When in use, turn on the power, turn on the switch, turn on the feed pump, and provide power through the feed pump. The produced lubricating oil enters the inner cavity of the feed hopper 5 through the connecting pipe 11. The cold water tank 1207 is also provided with a replenishing port for replenishing cold water, which is convenient for the staff to replenish the cold water in the cold water tank 1207. After replenishing the cold water, the replenishing port is closed, and then the water replenishing pump is turned on. The water replenishing pump provides power so that the cold water in the cold water tank 1207 enters the cold water pipe 1203. The cold water pipe 1203 is fixed in the inner cavity of the sealing cover 1201, and a plurality of cooling pipes 1202 are penetrated. Through the action of the cold water pipe 1203, the contact area between the lubricating oil and the cooling pipe 1202 is increased, thereby improving the cooling efficiency of the device.

[0048] After the lubricating oil is cooled, the staff opens the cylinder 1001, and the cylinder 1001 provides power to drive the piston in the cylinder 7 to slide. The sliding of the piston drives the cooled lubricating oil in the feed hopper 5 to pass through the feed pipe 401, the guide groove 902, the guide groove, the feed pipe 403 in sequence, and enter the inner cavity of the cylinder 7;

[0049] Then, the electric push rod 903 is opened, and power is provided by the electric push rod 903, and the swing rod 904 is driven to rotate by the electric push rod 903. The rotation of the swing rod 904 will drive the valve core 901 fixed to the swing rod 904 to rotate, and the rotation of the valve core 901 will drive the three guide grooves to be connected with the feed pipe 401, the delivery pipe 403 and the discharge pipe 402 respectively. Then, the valve is opened, and the pipeline between the discharge pipe 402 and the discharge nozzle 6 is opened. Power is provided by the cylinder 1001 to drive the piston to move toward the discharge nozzle 6. The movement of the piston will cause the lubricating oil in the cylinder 7 to enter the delivery pipe 403, the guide groove 902, the guide groove, the discharge pipe 402, and the discharge nozzle 6 in sequence. The lubricating oil discharged through the discharge nozzle 6 falls into the storage tank located directly below the discharge nozzle 6;

[0050] When the piston moves to collide with the end of the feed pipe 403, the storage tank is not yet filled completely, so the valve is closed. The pipeline between the discharge nozzle 6 and the discharge pipe 402 is disconnected, the storage tank is sealed, the storage tank is taken out, and another empty storage tank is replaced. The electric push rod 903 provides power to drive the rocker arm 904 to rotate in the opposite direction, thereby driving the valve core 901 to rotate in the opposite direction, where two guide grooves 902 are respectively connected to the feed pipe 401 and the discharge pipe, and the remaining guide grooves 902 collide with the bottom of the inner cavity groove of the guide device 4 and are closed by the bottom of the inner cavity groove of the guide device 4. Repeat the above operation until the storage tank is filled completely.

[0051] After one of the storage tanks is filled, the valve, the electric push rod 903 and the cylinder 1001 are closed, the filled storage tank is sealed, the storage tank is taken out, and an empty storage tank is replaced, and the above operation is repeated until the filling of several storage tanks is completed;

[0052] After the work is completed, disconnect the pipeline between the water inlet end 1205 of the cold water pipe 1203 and the outlet of the water supply pump 1208, as well as the pipeline between the water outlet end 1206 of the cold water pipe 1203 and the cold water tank 1207, remove the inspection cover 1204, inspect the cold water pipe 1203, then remove the sealing cover 1201, and rinse the lubricating oil adhering to the sealing cover 1201.
