Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging sealing test technology, specifically a rapid testing structure for lock cap sealing, which is particularly suitable for lock cap sealing test of products such as collagen drinks and health foods that have high requirements for packaging sealing. Background Technology
[0002] In the production of collagen drinks and health foods, the airtightness of the product packaging is crucial. Good sealing not only prevents the product from contacting external air and moisture during storage and transportation, avoiding spoilage and nutrient loss, but also effectively prevents microbial contamination, ensuring product quality and safety. Poorly sealed packaging can lead to premature product failure, causing economic losses and potentially even food safety issues.
[0003] Existing testing equipment also fails to adequately meet practical needs. Some equipment has cumbersome testing procedures, requiring multiple manual operations and adjustments, consuming significant time and manpower, and exhibiting low testing efficiency, making rapid batch testing impossible. Furthermore, most equipment cannot simultaneously assess the sealing of multiple products, limiting its testing capacity. Additionally, placing the sealed containers into the testing chamber during testing and removing them afterward is cumbersome, causing considerable inconvenience for users.
[0004] In view of this, we propose a rapid detection structure for the sealing performance of the lock cover. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a rapid detection structure for the sealing performance of the lock cover.
[0006] The technical solution of this utility model is:
[0007] A rapid sealing performance testing structure for collagen drink or health food caps includes a base plate and a vertical support plate fixed to the base plate. A testing box is located above the base plate, containing several testing chambers, each equipped with a pressure sensor. Two fixing plates are fixed to the front of the vertical support plate, and the testing box is fixed to both plates. An upper cover plate and a lower cover plate are located above and below the testing box, respectively. A guide block is integrally formed on the top of the lower cover plate at the bottom of each testing chamber. A corrugated pipe is installed on the top of each testing chamber. A top plate is integrally formed on the top of the vertical support plate, and a multi-outlet connecting pipe connected to the corrugated pipes is fixed on the top plate. An air pump is fixed to the rear outer wall of the vertical support plate, and the air pump's suction pipe is connected to the multi-outlet connecting pipe. By using a testing box with multiple testing chambers and pressure sensors, along with the corrugated pipes, multi-outlet connecting pipe, and air pump, the sealing performance of multiple collagen drink or health food caps can be tested simultaneously. The air pump draws air from the detection chamber through multiple outlet connecting pipes and a bellows. If the lock cover is not properly sealed, outside air will enter the detection chamber, causing the pressure sensor to detect the pressure change, thereby quickly determining the lock cover's sealing performance and greatly improving detection efficiency.
[0008] As a preferred technical solution, a second hydraulic cylinder is fixedly installed on the top of the top plate. The piston rod of the second hydraulic cylinder is fixed to the top of the upper cover plate. When the piston rod of the second hydraulic cylinder is extended to its maximum length, the upper cover plate and the top of the detection box are tightly fitted together. This design ensures a good seal between the upper cover plate and the detection box through precise control of the second hydraulic cylinder.
[0009] As a preferred technical solution, two first hydraulic cylinders are symmetrically fixedly installed at the bottom of the base plate. The piston rods of the first hydraulic cylinders are fixedly connected to the bottom of the lower cover plate. When the piston rods of the first hydraulic cylinders are extended to their longest length, the lower cover plate is tightly fitted to the bottom of the detection box.
[0010] As a preferred technical solution, a second sealing gasket is fixedly installed at the bottom of the upper cover plate and the top of the lower cover plate, and the second sealing gasket fits tightly against the detection box. Combined with the sealing effect of the second hydraulic cylinder on the lower cover plate, a double seal is achieved at the top and bottom of the detection box, further enhancing the sealing performance of the detection structure.
[0011] As a preferred technical solution, the bottom of the upper cover plate is integrally formed with several inner extension blocks, which are inserted into the testing chamber. The inner extension blocks can further divide the testing chamber, so that the product to be tested in each testing chamber is in a relatively independent space during testing.
[0012] As a preferred technical solution, a first sealing gasket is fixedly installed on the outer ring wall of both the inner extension block and the guide block, and the first sealing gasket is in close contact with the inner ring wall of the detection chamber. Under the action of the first hydraulic cylinder and the second hydraulic cylinder, the second sealing gasket can further fill the gap between the upper cover plate, the lower cover plate and the detection box, enhance the sealing effect, effectively prevent air leakage, and ensure that the detection process is carried out in a sealed environment, thereby improving the detection accuracy and precision.
[0013] As a preferred technical solution, a support leg is fixedly installed at each of the four corners of the bottom of the base plate, and the height of the support leg is greater than the length of the first hydraulic cylinder. This design ensures stable support for the entire detection structure during operation.
[0014] As a preferred technical solution, an upper connecting pipe and a lower connecting pipe are fixed at the top and bottom of the corrugated pipe, respectively. The lower connecting pipe passes through the upper cover plate and the inner extension block and communicates with the interior of the detection chamber. The upper connecting pipe is fixed to the multi-outlet connecting pipe. The upper and lower connecting pipes at the top and bottom of the corrugated pipe are respectively connected to the multi-outlet connecting pipe and the interior of the detection chamber. The upper connecting pipe is fixed to the multi-outlet connecting pipe, ensuring a stable connection of the air extraction system. This allows the air extraction pump to smoothly extract air from the detection chamber through the corrugated pipe. At the same time, the corrugated pipe has a certain degree of flexibility, which can adapt to changes in the relative position between the detection box and the upper and lower cover plates during the detection process, ensuring the smooth progress of the detection process and the sealing effect.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention utilizes a detection box with multiple detection chambers and pressure sensors, along with a corrugated pipe, multi-outlet connecting pipe, and air pump, to simultaneously test the sealing performance of multiple collagen beverage or health food caps. The air pump draws air from the detection chambers through the multi-outlet connecting pipe and corrugated pipe. If the cap is not properly sealed, outside air enters the detection chamber, causing the pressure sensors to detect pressure changes and quickly determine the cap's sealing performance, significantly improving detection efficiency. Furthermore, the detection chambers are open at both the top and bottom, facilitating the removal of sealed containers placed inside the detection box, increasing ease of use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 This utility model provides a technical solution:
[0025] The lock cover sealing rapid detection structure includes a base plate 3 and a vertical support plate 1 fixed on the base plate 3. A detection box 2 is provided above the base plate 3. The detection box 2 has several detection chambers, and a pressure sensor is installed in each detection chamber. Two fixing plates 10 are fixedly installed on the front side of the vertical support plate 1. The detection box 2 is fixed to the two fixing plates 10. An upper cover plate 20 and a lower cover plate 21 are provided above and below the detection box 2, respectively. A guide block 22 is integrally formed on the top of the lower cover plate 21 at the bottom of each detection chamber. A corrugated pipe 8 is installed on the top of each detection chamber. A top plate 11 is integrally formed on the top of the vertical support plate 1. A multi-outlet connecting pipe 7 that communicates with several corrugated pipes 8 is fixed on the top plate 11. An air pump 9 is fixedly installed on the rear outer wall of the vertical support plate 1. The air pump 9's air extraction pipe 90 is connected to the multi-outlet connecting pipe 7. By setting up a detection box 2 with multiple detection chambers and pressure sensors, along with a bellows 8, a multi-outlet connecting pipe 7, and an air pump 9, the sealing performance of multiple collagen drink or health food caps can be tested simultaneously. The air pump 9 evacuates air from the detection chambers through the multi-outlet connecting pipe 7 and the bellows 8. If the cap is not properly sealed, outside air will enter the detection chamber, causing the pressure sensors to detect pressure changes, thus quickly determining the cap's sealing performance and greatly improving testing efficiency.
[0026] In a preferred embodiment, a second hydraulic cylinder 6 is fixedly installed on the top of the top plate 11. The piston rod of the second hydraulic cylinder 6 is fixed to the top of the upper cover plate 20. When the piston rod of the second hydraulic cylinder 6 is extended to its longest position, the upper cover plate 20 is tightly fitted to the top of the detection box 2. This design ensures a good seal between the upper cover plate 20 and the detection box 2 through precise control of the second hydraulic cylinder 6.
[0027] As a preferred embodiment, two first hydraulic cylinders 5 are symmetrically fixedly installed at the bottom of the base plate 3. The piston rods of the first hydraulic cylinders 5 are fixedly connected to the bottom of the lower cover plate 21. When the piston rods of the first hydraulic cylinders 5 are extended to their longest length, the lower cover plate 21 is tightly fitted to the bottom of the detection box 2.
[0028] In a preferred embodiment, a second sealing gasket 24 is fixedly installed at the bottom of the upper cover plate 20 and the top of the lower cover plate 21, and the second sealing gasket 24 is tightly fitted to the detection box 2. Combined with the sealing effect of the second hydraulic cylinder 6 on the lower cover plate 21, a double seal is achieved at the top and bottom of the detection box 2, further enhancing the sealing performance of the detection structure.
[0029] In a preferred embodiment, the bottom of the upper cover plate 20 is integrally formed with a plurality of inner extension blocks 200, which are inserted into the testing chamber. The inner extension blocks 200 can further divide the testing chamber, so that the product to be tested in each testing chamber is in a relatively independent space during testing.
[0030] In a preferred embodiment, a first sealing gasket 23 is fixedly installed on the outer ring wall of both the inner extension block 200 and the guide block 22, and the first sealing gasket 23 is in close contact with the inner ring wall of the detection chamber. Under the action of the first hydraulic cylinder 5 and the second hydraulic cylinder 6, the second sealing gasket 24 can further fill the gap between the upper cover plate 20, the lower cover plate 21 and the detection box 2, enhance the sealing effect, effectively prevent air leakage, and ensure that the detection process is carried out in a sealed environment, thereby improving the detection accuracy and precision.
[0031] As a preferred embodiment, a support leg 4 is fixedly installed at each of the four corners of the bottom of the base plate 3, and the height of the support leg 4 is greater than the length of the first hydraulic cylinder 5. This design ensures stable support for the entire detection structure during operation.
[0032] In a preferred embodiment, an upper connecting pipe 80 and a lower connecting pipe 81 are fixed at the top and bottom of the corrugated pipe 8, respectively. The lower connecting pipe 81 passes through the upper cover plate 20 and the inner extension block 200 and communicates with the interior of the detection chamber. The upper connecting pipe 80 is fixed to the multi-outlet connecting pipe 7. The upper connecting pipe 80 and the lower connecting pipe 81 at the top and bottom of the corrugated pipe 8 communicate with the multi-outlet connecting pipe 7 and the interior of the detection chamber, respectively. The upper connecting pipe 80 is fixed to the multi-outlet connecting pipe 7, which ensures a stable connection of the air extraction system, allowing the air extraction pump 9 to smoothly extract air from the detection chamber through the corrugated pipe 8. At the same time, the corrugated pipe 8 has a certain degree of flexibility, which can adapt to the relative position changes between the detection box 2 and the upper cover plate 20 and the lower cover plate 21 during the detection process, ensuring the smooth progress of the detection process and the sealing effect.
[0033] In use, the locking and sealing rapid detection structure of this utility model first seals the bottom of the detection box 2 with the lower cover plate 21. Then, the collagen drink or health food to be tested is placed in the detection chamber of the detection box 2. The bottom of the product is positioned in conjunction with the guide block 22 on the top of the lower cover plate 21 to ensure accurate placement. Next, the second hydraulic cylinder 6 on the top plate 11 is activated. The piston rod of the second hydraulic cylinder 6 extends, causing the upper cover plate 20 to move downward, so that the lower cover plate 21 and the upper cover plate 20 are tightly fitted to the bottom and top of the detection box 2, respectively. At the same time, the inner extension block 200 at the bottom of the upper cover plate 20 is inserted into the detection chamber, cooperating with the guide block 22 of the lower cover plate 21 to fix the product. During this process, the second sealing gasket 24 on the upper cover plate 20 and the lower cover plate 21, as well as the first sealing gasket 23 on the outer ring wall of the inner extension block 200 and the guide block 22, play their role in filling the gaps between the components and forming a good sealing space.
[0034] After sealing is completed, the air pump 9 on the rear side of the vertical support plate 1 is started. The air pump 9 evacuates air from each testing chamber through the air extraction pipe 90, the multi-outlet connecting pipe 7, and the bellows pipe 8. If the locking cover is well sealed, a stable negative pressure environment will be formed inside the testing chamber; if the locking cover is not well sealed, gas in the space sealed by the locking cover will enter the testing chamber through the gaps, causing the pressure inside the testing chamber to change. The pressure sensor installed in each testing chamber monitors the pressure inside the testing chamber in real time. When the pressure sensor detects a pressure change that exceeds the set range, it can be determined that the locking cover of the product in the corresponding testing chamber is not well sealed; if the pressure remains stable, it indicates that the locking cover is well sealed.
[0035] After the test is completed, the vacuum pump 9 stops working, the piston rods of the first hydraulic cylinder 5 and the second hydraulic cylinder 6 retract, and the upper cover plate 20 and the lower cover plate 21 separate from the test box 2, allowing the tested product to be removed for the next round of testing. The entire process, through the coordinated operation of all components, enables rapid and accurate testing of the sealing performance of collagen drinks and health foods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
