Description

Technical Field

[0001] The utility model relates to the field of sealing performance detection, in particular to a waterproof packaging detection device. Background Art

[0002] The vacuum sealing performance tester for detecting the sealing performance of waterproof packaging has a vacuum tank, a mainframe and a vacuum pump. When in use, water needs to be injected into the vacuum tank, and generally the height of the water cannot exceed the vacuum cavity in the tank lid. According to the feedback from personnel, the volume of the vacuum tank is large. When injecting water quickly, when the water line is close to the standard line and there is no reserved space for cutting off the water in advance, it is very easy for the water line to exceed the standard line and enter the vacuum cavity. On the contrary, when cutting off the water in a hurry before the water line approaches the standard line, the water injection volume often fails to meet the standard. Therefore, based on the above description and considering the cost of the vacuum sealing performance tester, it is necessary to propose an economical and practical remedial measure to make the water injection volume in the vacuum tank meet the standard.

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0024] The specific embodiments of the present utility model will be described below in conjunction with the drawings.

[0025] Embodiment 1

[0026] In this embodiment, a waterproof packaging detection device is proposed. Please refer to Figures 1-4 , the waterproof packaging detection device includes a host 1, a vacuum pump 4, and a vacuum tank 2. Among them, the mouth of the vacuum tank 2 is equipped with a tank cover 3.

[0027] Furthermore, there is a rubber pad (not shown in the figure) at the contact position between the tank cover 3 and the vacuum tank 2. The rubber pad is stuffed in the annular gap of the tank cover 3. After the tank cover 3 is closed on the mouth of the vacuum tank 2, a sealed space is formed inside the vacuum tank 2.

[0028] Please refer to Figure 3 , the tank cover 3 has a pressing part 11 extending into the vacuum tank 2. Its specific style is as Figure 3 shown. It has a receiving cavity inside, and there are several openings 12 at the bottom of the receiving cavity. The receiving cavity is communicated with the vacuum tank 2 through several openings 12. It should be noted that in this embodiment, several openings 12 are arrayed around the axis of the bottom of the receiving cavity. After the array, the bottom of the receiving cavity retains a solid hard bottom.

[0029] Furthermore, the bottom of the pressing part 11 is the standard line. Specifically, after the tank cover 3 is closed on the mouth of the vacuum tank 2, the highest level of the liquid surface in the vacuum tank 2 is flush with the bottom of the receiving cavity.

[0030] Please continue to refer to Figures 1-4 , the structure coinciding with the axis of the tank cover 3 is a screw tube 8. The screw tube 8 penetrates into the receiving cavity from the tank cover 3, and when the screw tube 8 rotates relative to the tank cover 3, it keeps a distance from the bottom of the receiving cavity or closely fits with the bottom of the receiving cavity.

[0031] Furthermore, there is a protrusion at the axis of the tank cover 3, and there is a thread adapted to the screw tube 8 inside the protrusion. In this way, when the screw tube 8 rotates relative to the protrusion, the position of the screw tube 8 relative to the tank cover 3 can be adjusted, and then it keeps a distance from the bottom of the receiving cavity or closely fits with the bottom of the receiving cavity.

[0032] Even further, after the screw tube 8 closely fits with the bottom of the receiving cavity, the receiving cavity and the inner lumen of the screw tube 8 are two independent cavities and are not communicated with each other. On the contrary, when the screw tube 8 keeps a slight distance from the bottom of the receiving cavity, the receiving cavity is communicated with the inner lumen of the screw tube 8.

[0033] It should be added that the contact area between the screw tube 8 and the bottom of the receiving cavity is a solid hard bottom. In addition, a rubber ring 13 is provided at the bottom of the screw tube 8, and the rubber ring 13 contacts the bottom of the receiving cavity before the screw tube 8 contacts the bottom of the receiving cavity.

[0034] Please refer to Figure 3, the part of the solenoid 8 located outside the vacuum tank 2 is provided with a solenoid extension 7, which is a screwing part for operating the rotation of the solenoid 8. When the solenoid 8 is in close contact with the bottom of the accommodation cavity, the solenoid extension 7 is in close contact with the tank cover 3 and forms a sealing structure.

[0035] Please refer to Figure 4 , there is also a syringe 10, which is connected to the solenoid 8. From the above description, it can be determined that when the solenoid 8 maintains a slight distance from the bottom of the accommodation cavity, the excessive water located in the accommodation cavity can be sucked. On the contrary, when the water volume in the vacuum tank 2 does not reach the standard, water for adjusting the water volume needs to be prepared in advance in the syringe 10, and the syringe 10 can be used to inject water into the accommodation cavity.

[0036] In this embodiment, there are also the following contents to be explained: First, the syringe 10 is provided with a third tube 9, which is combined with the solenoid 8; Second, the main machine 1 is a common device on the market, which has functions such as controlling the pumping time and pumping pressure of the vacuum pump 4, and can also maintain pressure and release pressure, etc.

[0037] Third, as Figure 2 and Figure 3 shown, the first tube 5 connects the vacuum pump 4 and the main machine 1, and the second tube 6 connects the vacuum tank 2 and the main machine 1. After connection, the package whose waterproof effect needs to be tested is placed in the vacuum tank 2 filled with water, and it is squeezed in combination with the tank cover 3 to make the package sink below the liquid level. Based on the parameters set by the main machine 1, the vacuum pump 4 creates a vacuum environment in the vacuum tank 2. By combining visual inspection and the pressure change in the tank, the sealing performance of the package is judged, and then the waterproof effect of the package is evaluated.

[0038] In the present utility model, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0039] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
