[0029] In the embodiment, the inner wall of the insertion hole 3 is provided with an inner thread section 11 for connecting with the outer thread 400 of the bottle mouth of the silver molecular sieve container 100. The threaded connection is sealed tightly. Thus, during the whole process of installing the silver molecular sieve container 100 in the connecting seat 2, the bottle mouth 200 of the silver molecular sieve container 100 and the insertion hole 3 of the connecting seat 2 always form a relatively closed space. After the opening tube 4 is inserted into the bottle mouth sealing pad 300, the silver molecules in the silver molecular sieve container 100 cannot leak out from the gap between the outer peripheral wall of the bottle mouth 200 and the hole wall of the insertion hole 3.

[0030] In the embodiment, the limiting and guiding mechanism comprises a first limiting member, a second limiting member, and a guiding hole provided on the bracket 1 for inserting the horizontal valve plate 8 to limit the moving direction of the horizontal valve plate 8. The first limiting member is used to limit the horizontal valve plate 8. When the horizontal valve plate 8 moves together with the dosing tube 9 to abut against the first limiting member, the upper tube opening of the dosing tube 9 is just communicated with the lower outlet 5 of the bottom surface 211 of the connecting seat 2, and at this time, the lower tube opening of the dosing tube 9 is just closed by the upper surface 611 of the horizontal plate 6. The second limiting member is used to limit the dosing tube 9. When the horizontal valve plate 8 moves together with the dosing tube 9 to abut against the second limiting member, the lower tube opening of the dosing tube 9 is just communicated with the filling opening 7 of the horizontal plate 6, and at this time, the upper tube opening of the dosing tube 9 is just closed by the bottom surface 211 of the connecting seat 2.

[0031] In the embodiment, the filling opening 7 of the horizontal plate 6 and the lower outlet 5 of the bottom surface 211 of the connecting seat 2 are arranged in left-right staggered manner. The filling opening 7 of the horizontal plate 6 is on the left side, and the lower outlet 5 of the bottom surface 211 of the connecting seat 2 is on the right side. The distance between the filling opening 7 of the horizontal plate 6 and the lower outlet 5 of the bottom surface 211 of the connecting seat 2 can ensure that, during the moving process of the horizontal valve plate 8 and the dosing tube 9, the dosing tube 9 is not communicated with the filling opening 7 before the lower outlet 5 is completely closed by the upper surface 811 of the horizontal valve plate 8. Only when the lower outlet is completely closed by the upper surface 811 of the horizontal valve plate 8, the dosing tube 9 is communicated with the filling opening 7. The guiding hole is left-right oriented. The first limiting member is a left limiting block 12 fixed on the left bracket 1 of the horizontal valve plate 8. The second limiting member is a right limiting block 13 fixed on the horizontal plate 6 on the right side of the filling opening 7.

[0032] In the embodiment, the support is a horizontal support plate 14 horizontally installed in the insertion hole 3, a through hole is arranged on the horizontal support plate 14, the open pipe 4 is fixedly installed on the upper surface of the horizontal support plate 14, and the lower pipe opening of the open pipe 4 is in communication with the through hole of the horizontal support plate 14. In this way, when the silver molecular sieve container 100 is completely screwed into the insertion hole 3 of the connecting seat 2, the bottle mouth sealing gasket 300 of the silver molecular sieve container 100 is just pressed on the horizontal support plate 14 in the insertion hole 3, and through the cooperation of the horizontal support plate 14 and the bottle mouth sealing gasket 300, the silver molecules in the silver molecular sieve container 100 can be further prevented from leaking to the outside from the gap between the outer peripheral wall of the bottle mouth 200 and the hole wall of the insertion hole 3.

[0033] Before the sub-packaging is performed, the horizontal valve plate 8 is first moved leftwards along the guide hole, and in the process of moving leftwards, the horizontal valve plate 8 drives the dosing tube 9 to move leftwards together until the horizontal valve plate 8 is pushed leftwards to abut against the left limiting block 12, at this time, the dosing tube 9 is just moved leftwards to correspond to the lower outlet 5 of the bottom surface 211 of the connecting seat 2, and at this time, the lower pipe opening of the dosing tube 9 is just closed by the upper surface 611 of the horizontal plate 6.

[0034] When the sub-packaging is performed, the bottle mouth external cover of the silver molecular sieve container 100 storing the silver molecular sieve is first removed, at this time, the bottle mouth sealing gasket 300 of the bottle mouth 200 should be in a sealed state; then the silver molecular sieve container 100 is inverted to make the bottle mouth 200 downward, and then the silver molecular sieve container 100 is inserted and screwed into the insertion hole 3 of the connecting seat 2 through the bottle mouth external thread 400; when the silver molecular sieve container 100 is moved downwards along the insertion hole 3 of the connecting seat 2 to contact the open pipe 4, with the continuous downward movement of the silver molecular sieve container 100, the open pipe 4 is inserted into the bottle mouth sealing gasket 300 of the silver molecular sieve container 100 to make the open pipe 4 in communication with the inside of the silver molecular sieve container 100, until the silver molecular sieve container 100 is completely screwed into the insertion hole 3 of the connecting seat 2 to complete the installation of the silver molecular sieve container 100, at this time, the bottle mouth sealing gasket 300 of the silver molecular sieve container 100 is just pressed on the horizontal support plate 14 in the insertion hole 3, and through the cooperation of the horizontal support plate 14 and the bottle mouth sealing gasket 300, the silver molecules in the silver molecular sieve container 100 can be further prevented from leaking to the outside from the gap between the outer peripheral wall of the bottle mouth 200 and the hole wall of the insertion hole 3; since the silver molecular sieve container 100 is threadedly connected with the inner thread 11 of the insertion hole 3 of the connecting seat 2 through the bottle mouth external thread 400, the thread connection is sealed, in this way, in the whole process of installing the silver molecular sieve container 100 on the connecting seat 2, since the bottle mouth 200 of the silver molecular sieve container 100 and the insertion hole 3 of the connecting seat 2 always form a relatively closed space, it is ensured that the silver molecules in the silver molecular sieve container 100 will not leak to the outside from the gap between the outer peripheral wall of the bottle mouth 200 and the hole wall of the insertion hole 3 after the open pipe 4 is inserted into the bottle mouth sealing gasket 300.

[0035] After the silver molecular sieve container 100 is installed in the insertion hole 3 of the connecting seat 2, since the opening tube 3 has been inserted into the silver molecular sieve container 100 from the bottle mouth sealing gasket 300 at this time, the silver molecular sieve in the silver molecular sieve container 100 will automatically fall into the quantitative tube 9 through the opening tube 4, the lower outlet 5 and the feeding port 10 in sequence until the quantitative tube 9 is filled with the silver molecular sieve;

[0036] Then, the storage workpiece or container for storing the silver molecular sieve is connected to the filling port 7, and then the horizontal valve plate 8 is moved to the right. During the movement of the horizontal valve plate 8 to the right, the horizontal valve plate 8 drives the quantitative tube 9 filled with the silver molecular sieve to move to the right to the filling port 7. During the movement of the horizontal valve plate 8 and the quantitative tube 9 to the right, since the upper surface 811 of the horizontal valve plate 8 is always in sealing contact with the bottom surface 211 of the connecting seat 2 and the lower tube end of the quantitative tube 9 is always in sealing contact with the upper surface 611 of the horizontal plate 6, it is ensured that the inside of the connecting seat 2 and the inside of the quantitative tube 9 can always be in a relatively closed space during the movement of the horizontal valve plate 8 and the quantitative tube 9 to the filling port 7. Thus, during the movement of the horizontal valve plate 8 and the quantitative tube 9 to the filling port 7, the silver molecular sieve in the connecting seat 2 cannot fall out and cannot be in contact with the outside, and cannot be polluted by the outside gas. Meanwhile, it is also ensured that the silver molecular sieve in the quantitative tube 9 cannot be in contact with the outside and cannot be polluted by the outside gas.

[0037] Until the quantitative tube 9 moves to the right to abut against the right limiting block 13, at this time, the upper tube port of the quantitative tube 9 is closed by the bottom surface 211 of the connecting seat 2, and at this time, the lower tube port of the quantitative tube 9 corresponds to the filling port 7 of the horizontal plate 6. At this time, the silver molecular sieve in the quantitative tube 9 will fall into the storage workpiece or container from the filling port 7, and the quantitative packaging of the silver molecular sieve is completed.

[0038] The advantages of the utility model are:

[0039] (1) The quantitative packaging can be realized, the inaccuracy of the packaging quantity caused by the human subjective factors can be reduced, and the consistency of the packaging quantity is ensured.

[0040] (2) During the whole packaging process, the silver molecular sieve is always in a relatively closed space, the silver molecular sieve can be effectively prevented from being exposed to the working environment, the silver molecular sieve can be prevented from being polluted by the outside gas during the packaging process, the silver molecular sieve can be prevented from adsorbing the moisture and gas in the working environment during the packaging process, and the service life of the silver molecular sieve is prolonged.

[0041] (3) The consistency of the packaging quantity is realized by the packager during the packaging process, the complex link of weighing each time in the packaging process of the traditional process is reduced, and the packaging efficiency is greatly improved.

[0042] (4) Pure physical mechanical structure, no any electric structure, use is safer, and installation and maintenance are more convenient.

[0043] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any other form, and any modification or equivalent change made according to the technical essence of the present application still falls within the scope of the present application.
