[0017] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] Example 1 As shown in Figure 1 to Figure 6 As shown, an automatic oil-lubricating droplet is provided in the first aspect embodiment of this utility model. The injection device includes a mounting plate 1 and an oil storage tank 2 mounted on top of it. A rectangular frame 3 is fixedly installed inside the oil storage tank 2, which divides the oil storage tank 2 into two independent chambers: an oil storage area 4 and a heating area 5. The oil storage tank 2 has multiple heating tubes 6 fixedly installed in a rectangular arrangement inside, and the heating tubes 6 are located inside the heating zone 5; A stirring mechanism 7 and a temperature sensor 8 are respectively installed on the top of the oil storage tank 2, and the bottom walls of both the stirring mechanism 7 and the temperature sensor 8 extend to the inner side of the oil storage area 4. A drip tube 9 is fixedly installed at the bottom of the oil storage tank 2. A solenoid valve 10 and a flow sensor 11 are respectively installed on the outer side wall of the drip tube 9. A hydraulic assembly 12 is provided on one side of the oil storage tank 2, and one end of the hydraulic assembly 12 passes through one side wall of the oil storage tank 2 and is connected to the rectangular frame 3. A cleaning component 13 is provided on the other side of the oil storage tank 2, and one end of the cleaning component 13 extends to the inside of the drip tube 9.
[0019] The technical effect achieved by the above embodiment is as follows: In use, lubricating oil is added to the oil storage area 4 in the oil storage tank 2 through the filling pipe on the oil storage tank 2. Then, when the preset dripping time on the externally set PLC control device is reached, the PLC control device controls the solenoid valve 10 on the dripping pipe 9 to open, so that the lubricating oil can flow out from the dripping pipe 9 under the action of gravity. At the same time as flowing out, the PLC control device... The hydraulic assembly 12 is activated to compress air, ensuring that lubricating oil can flow from the drip tube 9. The flow rate is then detected by the flow sensor 11. When the flow rate detected by the flow sensor 11 reaches the preset value, the PLC control device controls the solenoid valve 10 to close. Then, the temperature sensor 8 monitors the temperature of the lubricating oil in the oil storage area 4. When the temperature is lower than the preset value, the PLC control device controls the heating tube 6 to heat the water in the heating area 5. The heat is then conducted to the oil storage area 4 through the rectangular frame 3, thereby heating the lubricating oil and improving its fluidity, ensuring that it can still flow smoothly under low temperature conditions. Finally, the PLC control device activates the cleaning assembly 13 to blow air to clean the drip tube 9, preventing it from being blocked by dust or oil.
[0020] Example 2 As shown in Figure 1 to Figure 6As shown, an automatic oil injection and lubrication dripping device includes all the contents of Embodiment 1. In addition, the cleaning component 13 includes a filter box 1301 fixedly installed on one side of the oil storage tank 2. An air pump 1302 is fixedly installed on the top of the filter box 1301. An air supply pipe 1303 is fixedly connected to the output end of the air pump 1302, and the other end of the air supply pipe 1303 is fixedly connected to the filter box 1301. An air blowing pipe 1304 is fixedly installed at the bottom of the filter box 1301, and the other end of the air blowing pipe 1304 extends to the inside of the drip tube 9.
[0021] The technical effect achieved by the above embodiment is as follows: air is blown into the filter box 1301 through the air pump 1302 and the air supply pipe 1303, and then the gas in the filter box 1301 passes through the filter screen and is blown out through the air blowing pipe 1304, thereby cleaning the drip tube 9 by blowing air and preventing the drip tube 9 from being blocked by dust or oil.
[0022] Example 3 As shown in Figure 1 to Figure 6 As shown, an automatic oil-lubricating drip device includes all the contents of Embodiment 1. In addition, a filter screen 19 is fixedly installed on the inner wall of the rectangular frame 3, and the filter screen 19 is located below the stirring mechanism 7. A connecting rod 20 is fixedly installed at the bottom of the stirring mechanism 7, and the bottom of the connecting rod 20 is fixed... A brush 21 is installed and is in contact with the drain pipe 17.
[0023] The technical effects achieved by the above embodiments are as follows: the filter screen 19 can filter the lubricating oil entering the drip tube 9, preventing impurities from clogging the drip tube 9. Then, when the stirring mechanism 7 stirs the lubricating oil in the oil storage area 4, the stirring mechanism 7 simultaneously drives the connecting rod 20, so that the brush 21 can brush the filter screen 19, thereby preventing 19 from clogging and accelerating the filtration speed of the lubricating oil.
[0024] Example 4 As shown in Figure 1 to Figure 6 As shown, an automatic oil-lubricating drip device includes all the contents of Embodiment 1. In addition, an inlet pipe 16 and a drain pipe 17 are fixedly installed on one side of the oil storage tank 2, and the drain pipe... 17 is located below the water inlet pipe 16. Solenoid valve 2 18 is installed on the outer wall of both the water inlet pipe 16 and the drain pipe 17.
[0025] The technical effect achieved by the above embodiment is as follows: when the water in the heating zone 5 of the oil storage tank 2 is replaced later, the solenoid valve 18 on the drain pipe 17 is opened so that the water in the heating zone 5 can be discharged from the oil storage tank 2. Then the solenoid valve 18 on the drain pipe 17 is closed and the solenoid valve 18 on the water inlet pipe 16 is opened so that the external water source can heat the heating zone 5 in the oil storage tank 2 from the water inlet pipe 16.
[0026] Example 5 As shown in Figure 1 to Figure 6 As shown, an automatic oil injection and lubrication dripping device includes all the contents of Embodiment 1. In addition, the hydraulic component 12 includes a fixed shell 1201 fixedly installed on one side of the oil storage tank 2. An electric telescopic rod 1202 is fixedly installed on the inner bottom wall of the fixed shell 1201. A piston plate 1203 is fixedly installed on the top of the electric telescopic rod 1202. A connecting pipe 1204 is fixedly installed on one side of the fixed shell 1201, and the other end of the connecting pipe 1204 passes through one side wall of the oil storage tank 2 and connects to the rectangular frame 3.
[0027] The technical effect achieved by the above embodiment is as follows: the electric telescopic rod 1202 is started by the PLC control device, and then the extended telescopic rod 1202 drives the piston plate 1203 to move, thereby enabling the piston plate 1203 to compress. While the air is compressed, it enters the oil storage area 4 through the connecting pipe 1204, ensuring that the lubricating oil can flow out from the drip pipe 9, and preventing the lubricating oil from being unable to flow out under the action of gravity due to its high viscosity and oil film thickness.
[0028] Example 6 As shown in Figure 1 to Figure 6 As shown, an automatic oil injection and lubrication dripping device includes all the contents of Embodiment 1. In addition, an air inlet pipe 14 is fixedly installed on the top of the fixed shell 1201, and a solenoid valve 15 is provided on the outer side wall of the air inlet pipe 14.
[0029] The technical effect achieved by the above embodiment is as follows: by controlling the opening of the solenoid valve 15 on the outside of the air intake pipe 14 through the PLC control device, when the retracted electric telescopic rod 1202 drives the piston plate 1203 to descend, air can enter the fixed shell 1201, thus avoiding affecting the piston movement of the hydraulic component 12.
[0030] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
