Description

Technical Field

[0001] The utility model relates to the technical field of foam pump seal gasket detection, in particular to a foam pump seal gasket detection mechanism for preventing leakage and misinstallation. Background Technique

[0002] During the production process of foam pumps, in order to ensure the correct installation of the seal gasket and avoid quality problems caused by leakage or misinstallation, it is necessary to efficiently and accurately detect the seal gasket on the pump shaft of the foam pump, so a foam pump seal gasket detection mechanism is often used.

[0003] For example, a foam pump seal gasket detection mechanism disclosed in the Chinese patent authorization publication number CN213592205U. In this existing device, when the detection drive rod moves downward, it presses down on one side of the detection lever where the detection drive rod is located, and at the same time, the detection lever on the side of the detection column is lifted upward and the detection column is lifted. Then, the detection device detects the moving height of the detection column to realize the detection of the installation state of the gasket. However, in actual application of this existing device, due to the relatively fixed size specifications of the detection drive rod and the detection lever, it can only detect drive rods with fixed sizes. When the size of the drive rod changes, it may be necessary to replace the entire detection lever or adjust the mechanism, which leads to the complexity of the detection process and the increase in cost. And when detecting the installation state of the gasket, this existing device mainly relies on the lifting height of the detection lever on the detection column, but this method may be affected by various factors (such as friction, wear, etc.), resulting in the accuracy of the detection result being affected. In addition, in the existing device, when an unqualified gasket is detected, it may be necessary to manually remove the unqualified drive rod from the detection device, which not only reduces the detection efficiency but also may introduce additional operation risks.

[0014] Compared with the prior art, the present utility model provides a detection mechanism for the sealing gasket of a foam pump to prevent leakage and misloading, and has the following beneficial effects:

[0015] 1. The leakage - proof and mis - loading - proof detection mechanism for the foam pump sealing gasket can achieve automatic adjustment of the position of the adjusting plate to ensure that the shaft diameters of multiple groups of adjusting plates can accurately match the foam pump shafts of different sizes, improving the adaptability and flexibility of the device. During the detection stage, the second motor drives the threaded rod to rotate, enabling the rubber pad on the extension plate to extrude the sealing gasket, ensuring the accuracy of the detection. At the same time, the real - time detection and data comparison functions of the distance sensor further enhance the detection accuracy, effectively avoiding problems such as missing installation and over - installation;

[0016] 2. The leakage - proof and mis - loading - proof detection mechanism for the foam pump sealing gasket can quickly determine whether the foam pump shaft is qualified by sorting and analyzing the detection data through the controller body. When an unqualified pump shaft is detected, the electric telescopic rod drives the push plate to export it from the second discharge frame, while the qualified pump shafts are directly exported from the first discharge frame. This efficient sorting mechanism not only improves production efficiency but also ensures the consistency of product quality. Through automatic detection and sorting, manual intervention is reduced, and the risk of human error is lowered, providing strong guarantee for the production and quality control of foam pump shafts.

[0026] To further understand the features, technical means, specific purposes, and functions achieved by the present utility model, the following provides a more detailed description of the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0027] Example 1: Please refer to Figures 1 - 7 , the present utility model provides a technical solution: a leak-proof and misloading-proof foam pump sealing gasket detection mechanism for detecting the sealing gasket 12 on the foam pump shaft 11, including a base 1, a support frame 2 is arranged on the top of the base 1, a first discharge frame 13 is arranged outside the support frame 2, a transmission device 14 for transmitting the foam pump shaft 11 is arranged in the support frame 2, a mounting frame 3 is arranged in the support frame 2, and an axle distance adjustment mechanism 4 that can be adjusted to detect foam pump shafts 11 of different size specifications is arranged in the mounting frame 3.

[0028] The axle distance adjustment mechanism 4 includes a mounting top plate 41 arranged in the mounting frame 3, a connecting frame 42 is arranged at the bottom of the mounting top plate 41, a connecting circular plate 43 is arranged at the bottom of the connecting frame 42, and multiple groups of adjusting plates 44 are slidably arranged in the connecting circular plate 43. It can achieve compatible detection of foam pump shafts 11 of different sizes, improving the versatility and flexibility of the detection mechanism 6.

[0029] Furthermore, the wheelbase adjustment mechanism 4 also includes a driving assembly 4a for driving the adjustment plate 44 to slide in the connecting circular plate 43. The driving assembly 4a is provided with a toothed disc 4a1, which is rotatably arranged on the top of the connecting circular plate 43. The toothed disc 4a1 is provided with an arc groove 4a2. A connecting column 4a3 is provided on the top of the adjustment plate 44, and the connecting column 4a3 is in contact with the arc groove 4a2. Through the design of the toothed disc 4a1 and the arc groove 4a2, the sliding adjustment of the adjustment plate 44 is realized, and the accuracy and stability of the wheelbase adjustment are improved.

[0030] Furthermore, the driving assembly 4a also includes a first mounting seat 4a4 disposed on the top of the connecting circular plate 43, a first motor 4a5 is disposed in the first mounting seat 4a4, a connecting gear 4a6 is disposed on the output shaft of the first motor 4a5, and the connecting gear 4a6 is meshed with the toothed disc 4a1. The introduction of the first motor 4a5 realizes the automatic adjustment of the position of the adjustment plate 44, thereby improving the detection efficiency and convenience.

[0031] Furthermore, a length adjustment mechanism 5 for detecting the sealing gasket 12 outside the pump shaft 11 of the foam pump is provided outside the adjustment plate 44, and the length adjustment mechanism 5 includes a connection frame 51 provided at the bottom of the adjustment plate 44, an extension plate 52 is movably provided in the connection frame 51, and a rubber pad 57 for squeezing the sealing gasket 12 is provided at the bottom of the extension plate 52. The design of the length adjustment mechanism 5 enables the detection mechanism 6 to accurately measure the installation status of the sealing gasket 12, providing a reliable basis for subsequent judgment.

[0032] Furthermore, the length adjustment mechanism 5 further includes a second mounting seat 54 disposed on the top of the adjustment plate 44, a second motor 55 is disposed in the second mounting seat 54, a threaded rod 56 is transmission-connected to the output shaft of the second motor 55, and the extension plate 52 is threadedly connected to the threaded rod 56. The combination of the second motor 55 and the threaded rod 56 enables precise adjustment of the position of the extension plate 52, thereby improving the accuracy and stability of the length adjustment.

[0033] Furthermore, the length adjustment mechanism 5 also includes a stop block 53 disposed outside the extension plate 52, and a limit slide groove is provided in the connection frame 51 for the stop block 53 to slide. The design of the stop block 53 and the limit slide groove prevents the extension plate 52 from excessively moving, thereby ensuring the stability and safety of the detection process.

[0034] Example 2: Please refer to Figure 8, and in combination with Embodiment 1, it is further obtained that a detection mechanism 6 for detecting the installation condition of the sealing gasket 12 outside the foam pump pump shaft 11 is provided in the support frame 2. The detection mechanism 6 includes a distance sensor 61 provided in the rubber pad 57 and a distance receiver 62 provided on the top of the adjusting plate 44 for receiving the signal of the distance sensor 61. A controller body 63 for processing the detection information of the distance receiver 62 is provided outside the support frame 2. The design of the detection mechanism 6 realizes the real-time monitoring of the installation condition of the sealing gasket 12, providing reliable data for subsequent judgment and processing.

[0035] Furthermore, the detection mechanism 6 further includes a third mounting seat 64 provided outside the support frame 2. An electric telescopic rod 65 is provided in the third mounting seat 64. A push plate 66 is provided at the output end of the electric telescopic rod 65. A second discharge frame 67 is provided on the side of the support frame 2 away from the push plate 66. The combination of the electric telescopic rod 65, the push plate 66 and the second discharge frame 67 realizes the automatic sorting and export of the unqualified foam pump pump shaft 11, improving the automation degree and detection efficiency of the detection mechanism 6.

[0036] In the actual operation process, first, according to the shaft diameter of the foam pump pump shaft 11, the position of the adjusting plate 44 is adjusted. The specific operation is as follows: Turn on the first motor 4a5 to drive the connecting gear 4a6 to rotate, and then drive the tooth disc 4a1 meshing with it to rotate. The arc-shaped groove 4a2 on the tooth disc 4a1 will pull the connecting column 4a3 to slide in the connecting circular plate 43, thereby adjusting the position of the adjusting plate 44. When the shaft diameters of multiple groups of adjusting plates 44 match the foam pump pump shaft 11, turn off the first motor 4a5. At this time, record the distance data when a single group of sealing gaskets 12 are installed outside the foam pump pump shaft 11 as the standard data.

[0037] Next, place the foam pump pump shaft 11 to be detected on the transmission device 14. Under the action of the transmission device 14, the pump shaft enters the bottom of the mounting frame 3 and then the transmission is paused.

[0038] Then, turn on the second motor 55 to drive the threaded rod 56 to rotate, so that the extension plate 52 moves in the connecting frame 51. The rubber pad 57 on the extension plate 52 will squeeze the sealing gasket 12 to ensure that the sealing gasket 12 is not tilted and avoid detection errors. After extrusion, the distance sensor 61 in the rubber pad 57 detects the distance data and transmits the data to the distance receiver 62. The controller body 63 compares the detected data with the standard data: if the detected data is less than the standard data, it is judged as a situation of missing installation; if the detected data is greater than the standard data, it is judged as a situation of over-installation; if the two are equal, it is a normal situation.

[0039] Finally, the controller body 63 sorts out the data and feeds it back to the electric telescopic rod 65. When an unqualified foam pump pump shaft 11 is detected, the electric telescopic rod 65 drives the push plate 66 to move, and exports the unqualified pump shaft from the second discharge frame 67. The qualified foam pump pump shaft 11 will not be pushed by the push plate 66 and is directly exported from the first discharge frame 13.

[0040] The above embodiments only represent one or several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
