Description

Technical Field

[0001] This utility model relates to the field of conveying and testing technology of instruments, and in particular to an air leakage detection mechanism for assembling a foam pump body. Background Technology

[0002] A manual foam pump is a device driven by human power, mainly used for conveying or mixing foam liquids. To ensure the quality of the foam pump before it leaves the factory, it will be tested for air leakage after the initial assembly of the foam pump body.

[0003] Currently, during the conveying process of foam pumps before air leakage testing, mechanical vibrations during feeding and conveying can cause the pump head to become stuck with adjacent pumps. If this is not detected and resolved in time, it can lead to abnormal entry of the foam pump into the testing device, affecting the air leakage testing process and even damaging the equipment. Utility Model Content

[0004] This utility model discloses an air leakage detection mechanism for assembling a foam pump body, which aims to solve the technical problem that the pressing head of the foam pump body may become stuck due to mechanical vibration and other factors, resulting in an abnormal state when it enters the detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a leak detection mechanism for assembling a foam pump body, comprising a lower plate and an upper plate, a support frame is provided on the side of the upper plate, the lower end of the support frame is fixedly connected to the upper surface of the lower plate, and a feeding bin is fixedly connected to the support frame, a side frame is fixedly connected to the support frame, and a spring rod is provided on the side of the feeding bin, a weighted ball is fixedly connected to the upper end of the spring rod, and a sensor is fixedly connected to the lower end of the spring rod, and the sensor is fixedly connected to the upper surface of the side frame.

[0006] In a preferred embodiment, the feeding bin includes a bin plate and a bin rod, with the bin rod close to a spring rod.

[0007] In a preferred embodiment, a drive motor is fixedly connected to the upper side of the feeding bin, and the output end of the drive motor is connected to a short shaft via a coupling. A through hole is provided on the feeding bin, and the other end of the short shaft passes through the through hole and is fixedly connected to a rotating disk. A soft brush is provided on the lower surface of the rotating disk.

[0008] In a preferred embodiment, the feeding bin has a notch section, and a discharge chamber is fixedly connected to the notch section, with the discharge chamber adjacent to the drive motor.

[0009] In a preferred embodiment, a discharge door is rotatably connected to the discharge chamber via a bearing. The discharge door fits into the opening of the feeding bin, and a support plate is provided on the discharge door. After the discharge door is closed, the support plate is flush with the bin plate of the feeding bin.

[0010] In a preferred embodiment, a top frame is fixedly connected to the upper surface of the discharge chamber, and a suspension seat is fixedly connected to the lower side of the top frame.

[0011] In a preferred embodiment, a back seat is fixedly connected to the outer surface of the discharge gate, and a hydraulic cylinder is rotatably connected to the suspension of the top frame via a bearing, with the lower end of the hydraulic cylinder rotatably connected to the back seat via a bearing.

[0012] As can be seen from the above, the air leakage detection mechanism for foam pump assembly provided by this utility model has the ability to perform self-check on the placement of the foam pump body during the conveying process before it enters the detection stage. It uses a spring rod to contact the pressing head of the foam pump body and uses a sensor to confirm that the foam pump body in each path is in the correct placement state. This avoids the foam pump body from crossing and getting stuck due to inconsistent pressing head states, which would cause the foam pump body to enter the upper plate incorrectly, affecting its conveying and obstructing the air leakage detection process. This improves the stability and safety of the air leakage detection device. Attached Figure Description

[0019] 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.

[0020] The leak detection mechanism for foam pump assembly disclosed in this utility model is mainly used in scenarios where the pump head is stuck due to mechanical vibration or other factors, and the abnormal state of the pump entering the detection device is not detected and eliminated.

[0021] Reference Figures 1-5 A leak detection mechanism for assembling a foam pump body includes a lower plate 1 and an upper plate 2. A support frame 3 is provided on the side of the upper plate 2. The lower end of the support frame 3 is fixedly connected to the upper surface of the lower plate 1. A feeding bin 4 is fixedly connected to the support frame 3. A side frame 5 is fixedly connected to the support frame 3. A spring rod 6 is provided on the side of the feeding bin 4. A weighted ball 8 is fixedly connected to the upper end of the spring rod 6. A sensor 7 is fixedly connected to the lower end of the spring rod 6. The sensor 7 is fixedly connected to the upper surface of the side frame 5.

[0022] The device can perform a self-check on the placement of the foam pump body during the conveying process before it enters the air leak detection stage. It uses a spring rod 6 to contact the pressing head of the foam pump body and a sensor 7 to confirm that the foam pump body in each path is in the correct placement state. This avoids the foam pump body from crossing and getting stuck due to inconsistent pressing head states, which would cause the foam pump body to enter the upper plate 2 incorrectly, affecting its conveying and obstructing the air leak detection process. This improves the stability and safety of the air leak detection device.

[0023] Reference Figure 3 and Figure 4 In a preferred embodiment, the feeding bin 4 includes a bin plate 401 and a bin rod 402, with the bin rod 402 close to the spring rod 6.

[0024] The bottom of the foam pump body is supported by the silo plate 401 and the silo rod 402 to ensure its conveying state.

[0025] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, a drive motor 9 is fixedly connected to the upper side of the feeding bin 4. The output end of the drive motor 9 is connected to a short shaft through a coupling. A through hole is provided on the feeding bin 4. The other end of the short shaft passes through the through hole and is fixedly connected to a rotary table 10. A soft brush 11 is provided on the lower surface of the rotary table 10.

[0026] When the foam pump body enters below the rotary table 10, the continuously operating drive motor 9 will drive the rotary table 10 to rotate. The rotary table 10 uses a soft brush 11 to brush the foam pump body below, which changes the state of the foam pump body in the feeding bin 4, ensuring that the pressing head of the foam pump body is facing outward, so as to facilitate the subsequent position detection of the spring rod 6 and facilitate its feeding into the upper plate 2.

[0027] Reference Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, the feeding bin 4 has an opening section, and a discharge chamber 12 is fixedly connected to the opening section, and the discharge chamber 12 is adjacent to the drive motor 9; a discharge door 13 is rotatably connected to the discharge chamber 12 via a bearing, the discharge door 13 fits into the opening of the feeding bin 4, and a support plate 14 is provided on the discharge door 13. After the discharge door 13 is closed, the support plate 14 is flush with the bin plate 401 of the feeding bin 4; a top frame 16 is fixedly connected to the upper surface of the discharge chamber 12, and a suspension seat 17 is fixedly connected to the lower side of the top frame 16; a back seat 15 is fixedly connected to the outer surface of the discharge door 13, and a hydraulic cylinder 18 is rotatably connected to the suspension seat 17 of the top frame 16 via a bearing, and the lower end of the hydraulic cylinder 18 is rotatably connected to the back seat 15 via a bearing.

[0028] When the foam pump body experiences abnormal conveying, the abnormal signal from the spring rod 6 and the sensor 7 will activate the hydraulic cylinder 18 to retract, causing the discharge door 13 to rise and flip upwards, so that the abnormally placed foam pump head falls to the position of the discharge chamber 12, preventing the abnormally placed foam pump body from entering the air leakage detection device.

[0029] Working principle: The device is used for the auxiliary placement of foam pumps before air leakage testing, ensuring that the foam pumps enter in the state required for air leakage testing. After sorting, the foam pumps are continuously conveyed from the feeding bin 4 to the lower plate 1 and upper plate 2 for air leakage testing. During this process: when the foam pump is inside the feeding bin 4 and enters below the rotating disc 10, the continuously operating drive motor 9 drives the rotating disc 10 to rotate. The rotating disc 10 uses a soft brush 11 to brush the foam pump below, ensuring that the foam pump is properly positioned within the feeding bin. When the state within 4 changes (the bottom of the foam pump body is supported by the bin plate 401 and bin rod 402, and one side is blocked by the bin wall plate of the feeding bin 4; the pressing head of the foam pump body faces outwards during normal conveying), the pressing head of the foam pump body will contact the spring rod 6 when passing through it. After receiving the signal, the sensor 7 ensures that the pressing head of the foam pump body faces outwards; when the foam pump body experiences abnormal conveying, that is: due to factors such as mechanical vibration during the feeding and conveying process, the pressing head of the foam pump body faces inwards and gets stuck with the adjacent pump body (e.g. Figure 3As shown), at this time, the brush of the rotating disc 10 cannot make the pressing head of the foam pump body face outward, and it cannot make contact with the spring rod 6 when passing through it. The sensor 7 receives an abnormal signal and feeds it back to the hydraulic cylinder 18. The hydraulic cylinder 18 retracts and drives the discharge door 13 to lift and flip upward. The abnormally placed foam pump head falls at the discharge chamber 12 position because it lacks the support plate 14 of the discharge door 13 to support it at the bottom. Then the hydraulic cylinder 18 extends and resets. The foam pump body that meets the detection conditions is conveyed into the station (the corresponding position of the upper plate 2 and the lower plate 1). The station is connected to the air inlet pipe, and the other end of the air inlet pipe is connected to the detection machine. When the air inlet pump delivers gas, one end is delivered to the station and the other end is delivered to the detection machine. At this time, the air inlet pump is closed, and the detection machine and the station are connected. If there is a gas leak in the station, the gas volume of the detection machine will change. Therefore, the product is detected to be leaking and marked, and it is rejected when it is discharged.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
