[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5A piston detection device for an emulsion pump includes a workbench 1, on which a conveyor belt 2, a feeding mechanism 3, and a pressing mechanism 4 are arranged. There are two conveyor belts 2, which are spaced apart. The feeding mechanism 3 is located at the starting end of the conveyor belt 2, and the pressing mechanism 4 is located in the middle of the conveyor belt 2. The feeding mechanism 3 includes a trapezoidal feeding box 31 arranged on the workbench 1. The feeding box 31 has an opening structure at the top and bottom, and its opening gradually narrows from top to bottom. A rotating wheel 32 is arranged at the lower opening. The output shaft of a feeding motor 34 is connected to the axis of the rotating wheel 32. The feeding motor 34 is installed on the outer wall of the feeding box 31. Several grooves 33 are distributed around the edge of the rotating wheel 32, and the bottom end of the rotating wheel 32 is exposed outside the feeding box 31. A feeding pipe 35 is arranged directly below the rotating wheel 32, and the bottom end of the feeding pipe 35 is perpendicular to the interval between the two conveyor belts 2.

[0023] In use, the emulsion pumps are placed into the feeding box 31 with the same orientation. Then, the feeding motor 34 is turned on, driving the rotating wheel 32 to rotate. This causes the emulsion pump at the bottom of the feeding box 31 to enter the groove 33. The rotation of the rotating wheel 32 rotates the emulsion pump in the groove 33 to the outside of the feeding box 31, where it falls into the feeding pipe 35 under gravity. From there, it falls onto the two conveyor belts 2. The two conveyor belts 2 operate synchronously, transporting the emulsion pump directly below the pressing mechanism 4 for pressing, thus detecting the piston of the emulsion pump. After detection, the pump is transported by the conveyor belts 2 to the next process step.

[0024] Specifically, in this embodiment, a stop block 36 is installed inside the feeding box 31. The upper end of the stop block 36 forms a downward convergence with the side wall of the feeding box 31, and the stop block 36 contacts the side edge of the rotating wheel 32 in the feeding direction. The stop block 36 can gather the emulsion pump at the bottom of the feeding box 31 at the rotating wheel 32, so that the emulsion pump can fall into the groove 33 on the rotating wheel 32. At the same time, the stop block 36 can cooperate with the side wall of the feeding box 31 to block one side of the rotating wheel 32, so that the emulsion pump can only fall from directly below the rotating wheel 32.

[0025] Specifically, in this embodiment, the upper part of the feeding pipe 35 is inclined downwards and has a feeding trough 37. The length of the feeding trough 37 is adapted to the thickness of the rotating wheel 32, and the lower part of the feeding pipe 35 is vertical. By setting the upper part of the feeding pipe 35 to be inclined and the lower part to be vertical, the emulsion pump can be adjusted from a horizontal state to a vertical state, so that the emulsion pump falls vertically on the conveyor belt 2.

[0026] Specifically, in this embodiment, the upper part of the feeding pipe 35 is connected to the wall of the feeding box 31, and a connecting rod 38 is connected to its lower curved surface. The other end of the connecting rod 38 is connected to the feeding box 31, so that the feeding pipe 35 can be connected to the feeding box 31 through the connecting rod 38, thereby improving the stability of the feeding pipe 35 and avoiding shaking during feeding, which would affect the accuracy of feeding.

[0027] Specifically, in this embodiment, the pressing mechanism 4 includes a device frame 41 mounted on the workbench 1. The device frame 41 extends through the surface of the workbench 1. A servo motor 42 is mounted on the top of the device frame 41. A bidirectional lead screw 43 is connected to the output shaft of the servo motor 42. The bidirectional lead screw 43 is rotatably connected to the device frame 41. A first moving block 44 and a second moving block 45 are threaded to both ends of the bidirectional lead screw 43, respectively. Both the first moving block 44 and the second moving block 45 are slidably connected to the device frame 41. A pressing block 46 and a water tank 47 are respectively mounted on the first moving block 44 and the second moving block 45. Both the pressing block 46 and the water tank 47 are on the same plane as the gap between the two conveyor belts 2.

[0028] When the pressing mechanism 4 is running, the servo motor 42 drives the bidirectional lead screw 43 to rotate, so that the first moving block 44 and the second moving block 45 respectively drive the pressing block 46 and the water tank 47 to move towards each other, so that the pressing block 46 presses down the pump head, and at the same time the water tank 47 rises to immerse the pump pipe in water, thereby realizing the detection of the emulsion pump piston.

[0029] Specifically, in this embodiment, the water tank 47 is detachably connected to the second movable block 45, which makes it easy for users to remove the water tank 47 for daily cleaning and water replacement.

[0030] Specifically, in this embodiment, a ramp 5 is provided on the side of the workbench 1. The ramp 5 is located at the end of the conveyor belt 2. A box for storing emulsion pumps can be placed below the ramp 5, so that the tested emulsion pumps can slide down the ramp 5 into the storage box, thereby completing the unified collection of materials.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
