[0036] like Figure 4-615, the telescopic rod 36 can limit the driving plate 35 to move up and down, the first motor 6 can provide a rotating force for the dial 5, the motor is a prior art, no further description is given; the inner wall of the center of the groove wheel 4 and the station disk 56 is fixedly connected with a rotating shaft, the rotating shaft is rotatably connected to the upper end of the bottom plate 1, and the limited groove wheel 4 and the station disk 56 can only rotate; the installation and shape of the dial 5 and the groove wheel 4 are as shown Figure 4 As shown, when the dial 5 rotates, it can drive the groove wheel 4 to rotate intermittently, and each time it rotates 90 degrees; Fig.15 As shown, the lower end surface of the driving plate 35 is fixedly connected to an extension seat 37, and the long pin 8 is fixedly connected to the inner wall of the lower end of the extension seat 37. The limited long pin 8 can only move up and down. The installation and shape of the long pin 8 and the cylindrical intermittent cam 7 are as shown in FIG. Figure 5 Or as shown in 6, when the cylindrical intermittent cam 7 rotates, it can drive the long pin 8 and the driving plate 35 to move up and down intermittently, that is, the driving plate 35 can move upward to the top position and then stop intermittently for a period of time, and then move downward to the bottom position and then stop intermittently for a period of time; through the cooperation of the dial 5, the groove wheel 4, the cylindrical intermittent cam 7, and the long pin 8, the groove wheel 4 and the work station disk 56 can be intermittently rotated, and the corresponding long pin 8 and the driving plate 35 are in a stopped state at the lowest end position. When the groove wheel 4 and the work station disk 56 stop intermittently, the corresponding long pin 8 and the driving plate 35 move upward to the top position, stop for a period of time, and then move downward to the bottom position.

[0037] The outer end surfaces of the work station seat 9 are slidably connected with vertical plates 10, and the clamping plates 11 are slidably connected to both sides of the corresponding outer end surfaces of the vertical plates 10. The lower sides of the inner end surfaces of the vertical plates 10 are fixedly connected with spring seats 54, and the upper end surfaces of the spring seats 54 are fixedly connected with fourth springs 55. The upper ends of the fourth springs 55 are fixedly connected to the corresponding lower end surfaces of the work station seat 9. The upper end surfaces of the work station seat 9 are slidably connected with two vertical plates 14 that can move inward or outward, and the clamping plates 11 are fixedly connected with extension pins 13, and the vertical plates 14 are respectively provided with first long key grooves 15 that match the extension pins 13.

[0038] like Figure 8-10 As shown, the vertical plate 10 can be slidably connected to the outer end surface of the station seat 9, and the clamping plate 11 can slide left and right on the outer end surface of the vertical plate 10. The vertical plate 10 is also provided with key-shaped through-hole grooves that match the extension pins 13, so that the vertical plate 10 can move left and right on the inner wall of the key-shaped through-hole groove; the installation and shape of the vertical plate 10, the spring seat 54, and the fourth spring 55 are as shown Fig. 9 As shown, the fourth spring 55 always has a downward driving force on the vertical plate 10, so that the vertical plate 10, the clamping plate 11, and the spring seat 54 are in the lowest end state under normal conditions. The installation and shape of the vertical plate 14, the first long key groove 15, and the extension pin 13 are as shown in FIG. Fig.10As shown, when the two vertical plates 14 move inward, the first long key groove 15 is engaged with the extension pin 13, which can drive the corresponding extension pin 13 and the clamping plate 11 to move inward, so that the clamping plate 11 clamps and fixes the sub-packaging bottle 12. Similarly, when the vertical plate 14 moves outward, the clamping plate 11 will be driven to move outward, and when the vertical plate 10, the clamping plate 11 and the extension pin 13 move upward or downward, it will not affect the clamping effect of the clamping plate 11 on the sub-packaging bottle 12, that is, the left and right coordinate position of the clamping plate 11 will not change when it moves up and down, and the clamping plate 11 will always be in a clamping state or an open state when moving up and down.

[0039] The inner walls of the workstation seat 9 are slidably connected with square sliders 17, and the upper end surfaces of the square sliders 17 are hinged with two first connecting rods 16, and the other ends of the first connecting rods 16 are hinged on the corresponding vertical plates 14. The inner walls of the workstation seat 9 are fixedly connected with first tension springs 18, and the other ends of the first tension springs 18 are fixedly connected to the corresponding square sliders 17. First sliding pins 19 are fixedly connected to the end surfaces on both sides of the square sliders 17. The workstation seat 9 is also provided with U-shaped guide plates 22 that can move up and down, and inclined grooves 23 matching the first sliding pins 19 are respectively opened on both sides of the U-shaped guide plates 22.

[0040] like Figure 11-12 As shown, the U-shaped guide plate 22 can be slidably connected to the end surfaces of both sides of the station seat 9, and the U-shaped guide plate 22 can move up and down on the end surfaces of both sides of the station seat 9, and the square slider 17 can slide inward or outward on the inner wall of the station seat 9. The first tension spring 18 always has an outward pulling force on the square slider 17, even if the square slider 17 is at the outermost end under normal conditions, through the hinge connection between the first connecting rod 16 and the vertical plate 14, when the square slider 17 moves outward, it can drive the two vertical plates 14 to move away from each other and toward both ends, and when the square slider 17 moves inward, it can drive the two vertical plates 14 The two guide plates 11 are moved closer to each other, that is, the opening and closing of the clamping plate 11 is controlled; when the U-shaped guide plate 22 moves upward, the corresponding first sliding pin 19 can be driven to move inward through the engagement of the inclined groove 23 and the first sliding pin 19. When the first sliding pin 19 moves inward, it will drive the corresponding square slider 17 and the first connecting rod 16 to move inward, and stretch the first tension spring 18. The outer end of the first connecting rod 16 will drive the corresponding two vertical plates 14 to move inward, that is, the corresponding clamping plate 11 moves inward to clamp and fix the sub-filling bottle 12.

[0041] The inner walls of the square slider 17 are slidably connected with trapezoidal wedge blocks 20, and the inner walls of the bottom ends of the square slider 17 are fixedly connected with first springs 21 that match the trapezoidal wedge blocks 20. The lower end surfaces of the workstation seats 9 are fixedly connected with two limit seats 25, and the inner walls of the limit seats 25 are respectively provided with stop pins 24 that match the trapezoidal wedge blocks 20.

[0042] like Fig.12As shown, the trapezoidal wedge block 20 can be slidably connected to the inner wall of the square slider 17 up and down, and the first spring 21 always has a downward elastic force on the trapezoidal wedge block 20, so that the trapezoidal wedge block 20 is in the lowest state under normal conditions. One end face of the trapezoidal wedge block 20 is an inclined surface, and the other end face is a right-angle surface. Through the cooperation of the set inclined surface, right-angle surface and stop pin 24, when the square slider 17 and the trapezoidal wedge block 20 move from the outside to the inside, the inclined surface of the trapezoidal wedge block 20 will meet the stop pin 24. At this time, the trapezoidal wedge block 20 is in the inclined surface and the stop pin 24, it will move upward, that is, the trapezoidal wedge block 20 will compress the first spring 21 and enter the inner wall of the square slider 17. When the trapezoidal wedge block 20 moves inwardly until it is out of contact with the stop pin 24, the trapezoidal wedge block 20 will move downward and reset under the elastic force of the first spring 21. When the trapezoidal wedge block 20 moves from the innermost side to the outer side, the right-angled surface of the trapezoidal wedge block 20 will meet the stop pin 24. At this time, the stop pin 24 will prevent the trapezoidal wedge block 20 from moving outward, that is, the clamping plate 11 can be in a stable clamping state.

[0043] The two sides of the lower end surface of the work station seat 9 are slidably connected with cross plates 26, and the stop pins 24 are fixedly connected to the corresponding cross plates 26. The lower end surfaces of the two cross plates 26 are respectively hinged with second connecting rods 27 extending downward. The lower ends of the two second connecting rods 27 are rotatably connected with a connecting pin 28. A second tension spring 34 is fixedly connected to the inner end surfaces of the two cross plates 26. The inner walls of the work station seat 9 are respectively slidably connected with square guide rods 29, and the square guide rods 29 are respectively provided with second long key grooves 30 that match the connecting pins 28.

[0044] like Figure 13-14 As shown, the second tension spring 34 always has an inward driving force on the two cross plates 26, so that the cross plates 26 and the stop pins 24 are at the innermost end under normal conditions, and the stop pins 24 can slide on the inner wall of the limit seat 25. When the two stop pins 24 move outward, the stop pins 24 can be disengaged from the trapezoidal wedge block 20. At this time, the stop pins 24 no longer block the trapezoidal wedge block 20, and the trapezoidal wedge block 20 and the square slider 17 will be reset under the tension of the first tension spring 18, that is, the two clamping plates 11 move outward and open; the square guide rod 29 can be slidably connected to the inner wall of the station seat 9 up and down; the connecting pin 28 can be The inner wall of the second long key groove 30 moves up and down. When the square guide rod 29 moves upward, the connecting pin 28 can slide on the inner wall of the second long key groove 30. When the square guide rod 29 moves upward until the lower inner wall of the second long key groove 30 contacts the connecting pin 28, the square guide rod 29 continues to move upward, which will drive the connecting pin 28 and the lower end of the second connecting rod 27 to move upward, and the upper end of the second connecting rod 27 will drive the corresponding two cross plates 26 to move outward. When the cross plates 26 move outward, they will drive the corresponding stop pins 24 to move outward, thereby controlling the stop pins 24 to disengage from the trapezoidal wedge block 20.

Fig.17As shown, the short guide rod 51 can be slidably connected to the inner wall of the guide seat 48 up and down, and the upper end surface of the short guide rod 51 is fixedly connected with an anti-slip pad 52. The function of the anti-slip pad 52 is to prevent the short guide rod 51 from being separated from the guide seat 48. The third spring 50 always has a downward driving force on the cylindrical seat 49, so that the cylindrical seat 49 is in the bottommost state under normal conditions, that is, the two valve plates 46 are at the innermost end to make the valve in a closed state; through the hinge connection between the third connecting rod 47, the cylindrical seat 49 and the valve plate 46, when the cylindrical seat 49 moves upward, it can drive the corresponding two valve plates 46 to move outward, at this time the through hole in the leakage nozzle is unblocked, that is, the valve is opened, and when the cylindrical seat 49 moves downward, it can make the two valve plates 46 move inward, at this time the through hole in the leakage nozzle is blocked, and the valve is closed; as shown in FIG. Fig.15 As shown, the driving plate 35 is arranged correspondingly with the U-shaped guide plate 22 of the loading area 57, the square guide rod 29 of the unloading area is arranged correspondingly, and the vertical plate 10 of the filling area 58 is arranged correspondingly. When the driving plate 35 moves upward, it can drive the U-shaped guide plate 22 of the loading area 57 to move upward, the square guide rod 29 of the unloading area to move upward, and the vertical plate 10 of the filling area 58 to move upward. When the U-shaped guide plate 22 of the loading area 57 moves upward, it will drive the square slider 17, the trapezoidal wedge block 20, etc. to move upward. When the trapezoidal wedge block 20 moves inward, it will drive the clamping plate 11 to move inward, that is, the sub-filling bottle 12 is clamped and fixed, and the corresponding trapezoidal wedge block 20 moves to the inner position of the two stop pins 24, so that the clamping plate 11 can be in a stable clamping state. At this time, when the station seat 9 rotates, the sub-filling bottle 12 can be driven to reach the filling area 58, the sealing area 59, and the unloading area in sequence. When the vertical plate 10 of the filling area 58 moves upward, it can drive the clamping plate 11 and the sub-filling bottle 12 to reach the filling area 58, the sealing area 59, and the unloading area. 2 moves upward synchronously, at this time, the sub-filling bottle 12 is located directly below the nozzle, and the clamping plate 11 will meet the cylindrical seat 49 when it moves upward. When the clamping plate 11 continues to move upward, it can drive the cylindrical seat 49 to move upward. When the cylindrical seat 49 moves upward, it will drive the corresponding valve plate 46 to move outward to open the valve. At this time, the sub-filling bottle 12 moves to the through hole of the nozzle, and the nano-microemulsion oil-displacing agent is accurately received; when the square guide rod 29 in the lower feeding area moves upward, it can drive the corresponding stop pin 24 to move outward. At this time, the trapezoidal wedge block 20 can move outward and reset under the tension of the first tension spring 18, and the corresponding clamping plate 11 will move outward, and the sub-filling bottle 12 will no longer be clamped and fixed. At this time, the sub-filling bottle 12 can be put on the unloading conveyor belt 3; through the cooperation of the equipment and the stirring device, the nano-microemulsion oil-displacing agent can be batched, accurately connected with the assembly line, and the whole process is automated, efficient, and small in human resources.

[0049] A preparation process of a nano-microemulsion oil-displacing agent comprises the following steps: S1. Prepare emulsion: mix oil and water and stir, add surfactant and sodium chloride, and continue stirring until uniform; S2. preparing a microemulsion: adding isopropanol to the emulsion, stirring evenly and then standing to obtain a homogeneous microemulsion; S3, preparation of sulfonated saponin: contacting saponin with fuming sulfuric acid for sulfonation reaction; then washing with deionized water and anhydrous ethanol alternately; drying at 50-80°C for 1-3 hours, and the sulfonation time is 3-6 hours; S4, polymerization reaction: In a reactor, the raw materials are mixed and stirred for 2-3 hours to form a uniform emulsion, and then part of the emulsion is transferred to a high-level tank, and the remaining emulsion is pre-polymerized by adding an initiator solution at 55-60°C. During the polymerization process, the temperature is maintained at 90-95°C and continued to be stirred for 1-1.5 hours. Finally, the temperature is lowered and the pH value is adjusted to 7-8 with a sodium hydroxide solution to obtain a nano-microemulsion oil-displacing agent, and then the nano-microemulsion oil-displacing agent is packaged through a preparation device to form a batch production.

[0050] When the present invention is in use, through the cooperation of the driving plate 35 and the clamping mechanism, when the driving plate 35 intermittently moves upward, the clamping plate 11 of the loading area 57 can be moved inward to clamp and fix the sub-filling bottle 12. After the sub-filling bottle 12 is clamped and fixed, the station plate 56 and the station seat 9 can rotate and move the sub-filling bottle 12 to the next station area, that is, the filling area 58. When the driving plate 35 moves upward, the clamping plate 11 of the filling area 58 will move upward and open the valve. When the valve is opened, the nano-microemulsion oil-displacing agent in the stirring device will flow into the sub-filling bottle 12. At this time, the clamping plate 11 is still in a clamping state in the filling area 58 and the sealing area 59, that is, the clamping plate 11 can continuously move. The sub-filling bottle 12 arrives at the filling area 58, the sealing area 59, and the unloading area 60 in sequence. When the filled sub-filling bottle 12 continues to rotate 90 degrees, it can reach the sealing machine 53. When the sealing machine 53 is working, the sub-filling bottle 12 can be sealed. When the clamping plate 11 and the sub-filling bottle 12 arrive at the unloading area 60, the driving plate 35 moves upward to move the clamping plate 11 outward, so that the sub-filling bottle 12 is placed on the unloading conveyor belt 3, and the packaged nano-microemulsion oil-displacing agent is moved to a designated position through the unloading conveyor belt 3. Through the cooperation of the equipment and the stirring device, the nano-microemulsion oil-displacing agent can be batch-filled and accurately connected to the assembly line, and the whole process is automated, efficient, and small in human resources.
