DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Please refer to Figures 1-5 , the present utility model provides the following technical solutions: It includes a support base 1 and a conveyor belt 11. The conveyor belt 11 is installed inside the support base 1. The top of the support base 1 is fixedly connected with a closing plate 2. The top of the closing plate 2 is fixedly connected with a supporting cover plate 21. An observation hole 22 is opened on one side of the supporting cover plate 21. Two linkage blocks 23 are slidably connected to the top of the closing plate 2. The bottom ends of the two linkage blocks 23 are both fixedly connected with connecting blocks 24. The bottom ends of the two connecting blocks 24 are both fixedly connected with clamping rings 25. The two clamping rings 25 are corresponding in position. One side of the closing plate 2 is fixedly connected with an extension bin 3. Light-shielding cloth 31 is installed inside the extension bin 3 and on both sides of the closing plate 2. The top of the closing plate 2 is fixedly connected with a discharging bin 4. A spray head 41 is arranged below the discharging bin 4.
[0018] In this implementation: The support base 1 is used to support and connect various components, so as to complete the leakage test operation of the spray through the cooperation of other components. Inside the support base 1, a conveyor belt 11 is installed. The conveyor belt 11 is used to convey the spray, so that the spray can be conveyed to a suitable position and continue to convey the tested spray, thereby achieving the purpose of carrying out the leakage test of the spray in an assembly line operation and improving the detection efficiency of the leakage test of the spray. The closed plate 2 fixed to the top of the support base 1 is used to block the surrounding light. On the top of the closed plate 2, a supporting cover plate 21 is fixed. The supporting cover plate 21 is used to support components such as the discharge bin 4. On one side of the closed plate 2, an observation hole 22 is provided. The observation hole 22 is used to make space for the staff to observe the inside of the closed plate 2. The staff can align the eye position with the observation hole 22 to observe the inside of the closed plate 2 and complete the detection work of the leakage situation of the spray. On one side of the closed plate 2, an extension bin 3 is fixed. The extension bin 3 is used to block the light and prevent the light from irradiating the inside of the closed plate 2 through the observation hole 22. On one side of the extension bin 3, a light-shielding cloth 31 is fixed. Light-shielding cloths 31 are fixed on both sides of the closed plate 2. The light-shielding cloth 31 is also used to block the light and prevent the light from affecting the detection result. The light-shielding cloth 31 is a flexible structure. When the conveyor belt 11 conveys the spray, when the spray touches the light-shielding cloth 31, it can drive the light-shielding cloth 31 to move. When the spray moves to the inside of the closed plate 2, the light-shielding cloth 31 will drop again due to its own gravity to block both sides of the closed plate 2. After the conveyor belt 11 conveys the spray to a suitable position inside the closed plate 2, the drive motor installed above the closed plate 2 will drive the linkage block 23 to move through the cooperation of other components. There are two linkage blocks 23. During the process, the two linkage blocks 23 will respectively drive the connecting block 24 and the clamping ring 25 fixed to the bottom to move towards the spray until the clamping ring 25 moves to the outside of the spray to clamp and position the spray, so that the spray is located at the center position of the closed plate 2. At the top of the closed plate 2, a discharge bin 4 is fixed. Below the bottom of the discharge bin 4, a spray head 41 is provided. The discharge bin 4 will spray the fluorescent agent inside through the spray head 41. After the spray head 41 sprays the fluorescent agent, the fluorescent agent will settle downward on the outside of the spray. If the spray does not leak, the fluorescent agent will settle naturally. If the spray leaks, the spray will contact the fluorescent agent and drive the fluorescent agent to float. Since the light inside the closed plate 2 is blocked, the staff can clearly observe the movement track of the fluorescent agent, thereby ensuring the accuracy of the detection result of the spray.
[0019] The bottom end of the support base 1 is fixedly connected with a fixing frame 12, and one side of the support base 1 is fixedly connected with a guiding plate 13; the fixing frame 12 fixed to the bottom end of the support base 1 is used to support the support base 1, enabling the support base 1 to complete the support connection work for other components. The guiding plate 13 fixed to one side of the support base 1 is used to guide the spray agent, so that the spray agent can be stably conveyed to the inside of the closing plate 2 when being conveyed through the conveyor belt 11, and then through the cooperation of other components, the leakage detection test of the spray agent is completed.
[0020] Several transmission teeth 26 are fixedly connected to one side of the linkage block 23, and a driving gear 27 is rotatably connected to the top end of the supporting cover plate 21. The driving gear 27 meshes with the transmission teeth 26; the transmission teeth 26 fixed to one side of the linkage block 23 are used to drive the linkage block 23. A driving gear 27 is rotatably connected to the top end of the supporting cover plate 21, and the driving gear 27 is connected to the output end of the driving motor installed above the closing plate 2, enabling the driving gear 27 to rotate. Since the driving gear 27 meshes with the transmission teeth 26, the driving gear 27 can drive the transmission teeth 26 and the linkage block 23 to move horizontally during rotation, thereby completing the clamping and positioning operation of the spray agent through the connecting block 24 and the clamping ring 25, so that the spray agent can be located at the center position of the closing plate 2, ensuring that when the fluorescent agent is ejected from the spray head 41, the fluorescent agent can settle downward around the outside of the spray agent, enabling the aerosol leaked from the spray agent to contact the fluorescent agent and drive the fluorescent agent to move, and then enabling the staff to complete the detection operation of the leakage situation of the spray agent by observing the movement track of the fluorescent agent.
[0021] A support rod 28 is fixedly connected to the top end of the closing plate 2, and a mounting plate 29 is fixedly connected to one side of the support rod 28; the support rod 28 fixed to the top end of the closing plate 2 is used to support the mounting plate 29, and the mounting plate 29 can carry the driving motor, so that the driving motor can be installed at the bottom end of the mounting plate 2, with the output end connected to the driving gear 27, and thus through the transmission of the driving gear 27 and the transmission teeth 26, the purpose of driving the linkage block 23 to move is achieved, enabling the connecting block 24 and the clamping ring 25 to clamp and position the spray agent at the center position of the closing plate 2, waiting for the staff to conduct the leakage detection test on the spray agent.
[0022] A feed pipe 42 is fixedly connected to the top end of the discharge bin 4, and a diversion pipe 43 is fixedly connected between the discharge bin 4 and the spray head 41; the feed pipe 42 fixed to the top end of the discharge bin 4 is used to introduce the powdered fluorescent agent into the discharge bin 4. A diversion pipe 43 is connected between the discharge bin 4 and the spray head 41, and a pump is installed inside the discharge bin 4, enabling the powdered fluorescent agent inside the discharge bin 4 to enter the spray head 41 and be discharged through the spray head 41, and then enabling the aerosol leaked from the spray agent to contact the fluorescent agent, so that the staff can make a judgment on whether the spray agent leaks by observing the movement track of the fluorescent agent.
[0023] Working principle and usage process of the utility model: When the staff needs to conduct a leakage detection test on the spray, the staff can place the spray above through the conveyor belt 11. The conveyor belt 11 will drive the spray to move. When the spray moves, it will contact the guiding plate 13 and be guided by the guiding plate 13 to enter the inside of the closing plate 2. A proximity switch is installed at the corresponding position between the inside of the closing plate 2 and the clamping ring 25. When the conveyor belt 11 drives the spray to move to the position corresponding to the clamping ring 25, the conveyor belt 11 will stop driving the spray. At this time, the driving motor installed above the closing plate 2 will drive the driving gear 27 to rotate. When the driving gear 27 rotates, it will drive the linkage block 23 to move horizontally through the transmission teeth 26. At this time, the connecting block 24 fixed to the bottom end of the linkage block 23 and the clamping ring 25 will move towards the spray, so that the spray can be clamped by the clamping ring 25 and positioned at the center of the closing plate 2. Then, the powdery fluorescent powder inside the discharge bin 4 will be introduced into the spray head 41 through the diversion pipe 43 and discharged through the spray head 41. Then, the staff can align their eyes with the observation hole 22 to observe the inside of the closing plate 2. At this time, the powdery fluorescent powder will settle downward around the spray. If the spray does not leak, the fluorescent powder will settle stably downward. When the spray leaks, the leaked aerosol will contact the fluorescent powder and drive the fluorescent powder to float, enabling the staff to judge whether the spray leaks by observing the movement track of the fluorescent powder. After the detection is completed, the clamping ring 25 will move back to its original position, and the conveyor belt 11 will continue to drive other sprays to move to the inside of the closing plate 2.
