Description

Technical Field

[0001] This utility model belongs to the field of nanomaterial encapsulation technology, specifically, it relates to an encapsulation mechanism for nano-silver sol. Background Technology

[0002] As a material with unique physical and chemical properties, silver nanosol has shown broad application prospects in many fields such as antibacterial, catalysis, and electronics. Ensuring the quality and stability of silver nanosol is crucial for its practical application, and the encapsulation process is a key step in ensuring the quality of silver nanosol. A suitable encapsulation mechanism can effectively protect silver nanosol from the influence of external environmental factors, thereby extending its service life and maintaining performance stability.

[0003] Currently, in the process of encapsulating nano-silver sol, due to the lack of a mechanism for testing the airtightness of the encapsulation container, traditional encapsulation methods rely solely on manual visual inspection, which cannot accurately identify potential defects such as minor breaks in the container itself. If an unqualified container is used for encapsulation, the nano-silver sol may leak or deteriorate, leading to a decline in product quality, increased defect rate, and increased production costs. In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a nano-silver sol encapsulation mechanism that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A packaging mechanism for nano-silver sol includes a base with a frame fixedly connected to it, and further includes: a sealing ring vertically connected to the base; a sealing airbag surrounding the outer wall of the sealing ring; a gas supply pipe connected to the sealing airbag; a vacuum extraction mechanism mounted on the frame for drawing a negative vacuum inside the packaging container when the sealing airbag seals the bottle opening; a vacuum instrument mounted on the sealing ring for testing the airtightness of the packaging container after vacuum extraction to determine if the bottle body is damaged; and a storage tank fixedly connected to the frame. The sealing ring has a feeding chamber for filling the packaging container with nano-silver sol, and the storage tank is connected to the feeding chamber via a feeding pipe equipped with a solenoid valve.

[0007] In order to filter the nano-silver sol passing through the feed pipe, preferably, the middle section of the feed pipe is connected to a filter tank, and a filter screen is provided inside the filter tank.

[0008] To improve the stability of the filter screen inside the filter canister, the filter canister is further composed of an upper shell and a lower shell, which are detachably connected. The mating surfaces of the upper shell and the lower shell are provided with snap-fit ​​grooves, and the filter screen is located in the snap-fit ​​grooves.

[0009] To facilitate the assembly and disassembly of the upper and lower housings, multiple fixing bolts are further included, and the lower housing is detachably connected to the upper housing via these bolts.

[0010] Preferably, the vacuum pumping mechanism includes a vacuum pump, a first gas supply pipe, and a second gas supply pipe. The vacuum pump is fixedly mounted on the base frame. One end of the first gas supply pipe is connected to the input end of the vacuum pump, and the other end is set on the sealing ring and connected to the packaging container. One end of the second gas supply pipe is connected to the output end of the vacuum pump, and the other end is connected to the sealing airbag.

[0011] In order to keep the pressure inside the sealed airbag constant, a pressure relief pipe is fixedly connected to the third air supply pipe, a pressure relief valve is installed on the pressure relief pipe, and a valve switch is installed on the third air supply pipe.

[0012] In order to drive the lifting seat to move the sealing ring up or down on the base frame, preferably, an electric telescopic rod is fixedly connected to the base frame, the telescopic end of the electric telescopic rod is fixedly connected to the lifting seat, and the sealing ring is fixedly connected to the lifting seat.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0014] This invention, through the sealing airbag, can be adapted to bottle mouths of different diameters according to the inflation volume, improving the versatility of the sealing mechanism, avoiding frequent replacement of parts due to differences in bottle mouth size, reducing costs, and expanding the scope of application;

[0015] By using a vacuum pump to enhance the sealing effect of the sealing airbag during vacuuming, a stable negative pressure encapsulation environment is created, reducing the contact between the nano silver sol and air, ensuring its stable performance and improving product quality.

[0016] By using vacuum instruments to test the airtightness of containers before packaging, damaged containers can be detected in time, ensuring packaging quality and reducing the defect rate. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] Example 1:

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A nano-silver sol encapsulation mechanism includes a base 1, a base frame 101 fixedly connected to the base 1, and further includes: a sealing ring 3 vertically connected to the base 1; a sealing airbag 301 surrounding the outer wall of the sealing ring 3; a gas delivery pipe 4 connected to the sealing airbag 301; a vacuuming mechanism installed on the base frame 101, used to evacuate the encapsulation container when the sealing airbag 301 seals the bottle opening; a vacuum instrument 305 installed on the sealing ring 3, used to perform airtightness testing on the encapsulation container after vacuuming, and to determine whether the bottle body of the encapsulation container is damaged; and a storage tank 5 fixedly connected to the base frame 101. The sealing ring 3 has a delivery chamber 502 for filling the encapsulation container with nano-silver sol, and the storage tank 5 is connected to the delivery chamber 502 through the delivery pipe 501, which is equipped with a solenoid valve.

[0026] The vacuum pump mechanism includes a vacuum pump 302, a first gas supply pipe 303, and a second gas supply pipe 304. The vacuum pump 302 is fixedly installed on the base frame 101. One end of the first gas supply pipe 303 is connected to the input end of the vacuum pump 302, and the other end is set on the sealing ring 3 and connected to the packaging container. One end of the second gas supply pipe 304 is connected to the output end of the vacuum pump 302, and the other end is connected to the sealing airbag 301.

[0027] A pressure relief pipe 401 is fixedly connected to the gas transmission pipe 3 4. A pressure relief valve is installed on the pressure relief pipe 401, and a valve switch is installed on the gas transmission pipe 3 4.

[0028] An electric telescopic rod 201 is fixedly connected to the base frame 101. A lifting seat 2 is fixedly connected to the telescopic end of the electric telescopic rod 201, and a sealing ring 3 is fixedly connected to the lifting seat 2.

[0029] When using it, first put the nano silver sol to be encapsulated into the storage tank 5, and place the encapsulation container in a suitable position on the base 1 to prepare for the subsequent encapsulation operation.

[0030] Then, the electric telescopic rod 201 on the base frame 101 is activated. Its telescopic end drives the lifting seat 2 to descend, causing the sealing ring 3 fixed on the lifting seat 2 to descend accordingly. After the sealing ring 3 is inserted into the bottle mouth of the packaging container, the valve switch on the gas supply pipe 3 4 is opened, and air is inflated into the sealing airbag 301 through the gas supply pipe 3 4. The sealing airbag 301 expands and fits against the inner wall of the bottle mouth of the packaging container to achieve a seal on the bottle mouth. At the same time, by controlling the inflation amount, it can be adapted to the bottle mouth of packaging containers with different diameters.

[0031] Subsequently, vacuum pump 302 is turned on. Vacuum pump 302 draws air from the sealed container through gas supply pipe 303, gradually creating a negative pressure environment inside the container. At the same time, the output end of vacuum pump 302 inflates the sealing air bag 301 through gas supply pipe 304, causing the sealing air bag 301 to expand further, sealing the bottle mouth more tightly and enhancing the sealing effect.

[0032] Once the predetermined vacuum level is reached, the vacuum pump 302 stops working. At this time, the vacuum instrument 305 installed on the sealing ring 3 begins to perform an airtightness test on the packaging container. Based on the pressure change, it is determined whether there is any damage to the bottle body of the packaging container. If the airtightness test result is qualified, the solenoid valve on the feed pipe 501 is opened. Under the action of pressure difference, the nano silver sol in the storage tank 5 is filled into the packaging container through the feed pipe 501 and the feed chamber 502.

[0033] After filling is completed, close the solenoid valve and open the valve switch on the gas supply pipe 3 4 to allow the gas in the sealing airbag 301 to be discharged through the gas supply pipe 3 4. If the pressure in the sealing airbag 301 is too high during the inflation process, the pressure relief valve on the pressure relief pipe 401 will automatically open to release some gas. After that, start the electric telescopic rod 201 again. Its telescopic end will drive the lifting seat 2 to rise, and the sealing ring 3 will rise accordingly, so that the sealed container can be taken out.

[0034] In summary, the sealing airbag 301 seals the bottle opening by inflation and can be adapted to bottle openings of different diameters according to the inflation volume, which greatly improves the versatility of the sealing mechanism, reduces the trouble of replacing equipment parts due to differences in bottle opening size, lowers the cost of use, and expands the scope of application.

[0035] The vacuum pump 302 enhances the sealing effect of the sealing airbag 301 while drawing a vacuum, creating a stable negative pressure encapsulation environment for the nano-silver sol, effectively reducing the contact between the nano-silver sol and air, preventing its oxidation and aggregation, ensuring the stable performance of the nano-silver sol, and improving product quality.

[0036] The Vacuum Instrument 305 checks the airtightness of the container before packaging, which can detect damaged containers in time and avoid problems such as leakage or deterioration of nano-silver sol caused by the use of unqualified containers, thereby ensuring packaging quality and reducing the defect rate.

[0037] It should be noted that both air supply pipe 303 and air supply pipe 304 are equipped with one-way valves, and both air supply pipe 303 and air supply pipe 304 are flexible and retractable hoses. Therefore, air supply pipe 303 and air supply pipe 304 will not interfere with the lifting of the lifting seat 2.

[0038] Example 2:

[0039] Reference Figure 1 , Figure 3 A nano-silver sol encapsulation mechanism is basically the same as that in Example 1. Furthermore, the middle section of the feed pipe 501 is connected to a filter tank 6, and a filter screen 604 is provided inside the filter tank 6.

[0040] After the nano-silver sol flows out of the storage tank 5, it first enters the conveying pipe 501 and then flows into the connected filter tank 6. When the nano-silver sol passes through the filter screen 604 in the filter tank 6, impurities larger than the mesh size are blocked by the filter screen 604, while the nano-silver sol passes through smoothly, thus achieving the filtration of the nano-silver sol. The filtered nano-silver sol continues to flow through the conveying pipe 501 to the conveying chamber 502, and is finally filled into the packaging container.

[0041] In summary, by setting up a filter tank 6 and a filter screen 604 in the middle section of the feed pipe 501, impurities in the nano-silver sol are effectively filtered out, ensuring the purity of the nano-silver sol filled into the packaging container, thereby improving product quality and reducing the adverse effects of impurities on the performance of the nano-silver sol.

[0042] Example 3:

[0043] Reference Figure 3A nano-silver sol encapsulation mechanism is basically the same as that in Example 1. Furthermore, the filter tank 6 is composed of an upper shell 601 and a lower shell 602. The upper shell 601 and the lower shell 602 are detachably connected. The mating surfaces of the upper shell 601 and the lower shell 602 are provided with snap-fit ​​grooves, and the filter screen 604 is located in the snap-fit ​​grooves.

[0044] When installing the filter screen 604, first place the filter screen 604 in the snap-fit ​​groove of the upper housing 601 or the lower housing 602, then fit the upper housing 601 and the lower housing 602 together so that the filter screen 604 is located in the space formed by the two snap-fit ​​grooves. After that, fix the upper housing 601 and the lower housing 602 together by disassembly connection method such as bolt connection. When it is necessary to clean or replace the filter screen 604, loosen the disassembly connection part, separate the upper housing 601 and the lower housing 602, and then you can take out the filter screen 604.

[0045] In summary, the snap-fit ​​groove, combined with the detachable upper housing 601 and lower housing 602 structure, facilitates the installation, disassembly, and maintenance of the filter screen 604. This allows for regular cleaning or replacement of the filter screen 604, ensuring its filtration effect remains consistently good. Consequently, this continuously guarantees the filtration quality of the nano-silver sol, extends the service life of the filter tank 6, and reduces equipment malfunctions and product quality issues caused by clogging or damage to the filter screen 604.

[0046] It also includes multiple fixing bolts 603, and the lower housing 602 is detachably connected to the upper housing 601 through the multiple fixing bolts 603;

[0047] The fixing bolt 603 connects the lower housing 602 and the upper housing 601 tightly through a threaded connection, providing sufficient fastening force to ensure the sealing and structural stability of the filter tank 6 during operation, prevent leakage of nano-silver sol, and ensure the stable operation of the filter screen 604.

[0048] In summary, the use of fixing bolts 603 for disassembly and connection is simple, convenient, and provides a secure connection. This facilitates the assembly and disassembly of the filter tank 6, allowing for quick opening of the filter tank 6 when maintenance of the filter screen 604 or cleaning of its interior is required, thus improving the maintainability of the equipment.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
