[0024] As shown in the accompanying Figures 1-5 A film permeation detection pretreatment device, comprising a body 1, a pretreatment gas path system and a modular jig 2, the pretreatment gas path system is arranged in the body 1 for the permeation pretreatment of the modular jig 2;A plurality of jig cavities capable of being placed in the modular jig 2 are arranged on the body 1, and the modular jig 2 is provided with a film detection cavity 5 for placing the film to be tested;The modular jig 2 is provided with a detection quality inlet 6, a detection quality outlet 7, a permeation quality inlet 8 and a permeation quality outlet 19, and the detection quality inlet 6, the detection quality outlet 7, the permeation quality inlet 8 and the permeation quality outlet 19 are all communicated with the film detection cavity 5;A membrane cavity sealing groove 9 is arranged along the outer periphery of the film detection cavity 5, and a membrane cavity sealing ring 10 for sealing the film detection cavity 5 is arranged in the membrane cavity sealing groove 9.The film permeation detection pretreatment device of the embodiment is a device specially used for the permeation rate pretreatment of the film to be tested, and its principle and advantages are that the film to be tested can be sealed, assembled and fixed in the film detection cavity 5 of the modular jig 2 to form a whole, a single pretreatment device can simultaneously place a plurality of modular jigs 2 for the permeation pretreatment of the film to be tested, and after running for a set time period to make the film to be tested reach permeation balance, the pretreated modular jig 2 can be directly transferred as a whole to the film permeation rate detection device to directly detect the permeation rate of the film to be tested, greatly facilitating the detection operation of the user.In addition, based on the film permeation detection pretreatment device of the utility model and the collocation of different pretreatment gas sources, the same permeation quality or different permeation quality different combinations of permeation pretreatment detection methods can be realized, such as one film permeation rate detection device matching multiple pretreatment devices, multiple film permeation rate detection devices matching a single pretreatment device, or multiple film permeation rate detection devices matching multiple pretreatment devices, effectively improving the efficiency and flexibility of the permeation rate detection of the film to be tested.

[0025] It is easy to understand that the modular jig 2 of the utility model is not limited to a unique specific shape structure, and in actual application, as long as it can be matched with the jig cavity of the film permeation detection pretreatment device, it can be connected to the pretreatment gas source through the pretreatment gas path system to realize the permeation pretreatment of the film to be tested placed in the film detection cavity 5 of the modular jig 2. Figure 2In the shown embodiment, the modular jig of the embodiment comprises an upper mold assembly 3 and a lower mold assembly 4, and in actual application, the upper mold assembly 3 and the lower mold assembly 4 are assembled to form a film detection cavity 5, that is, the modular jig of the structure can only place one film to be detected for permeation pretreatment in actual application, and the number of the films to be detected for pretreatment is the same as the number of the modular jigs 2 placed in full load operation of the film permeation detection pretreatment device. Based on the similar pretreatment principle, see the attached Figure 5 In another structure of the shown modular jig 2, the modular jig in the embodiment comprises an upper mold assembly 3, a middle mold assembly 301 and a lower mold assembly 4, and after the assembly and combination of the upper mold assembly 3, the middle mold assembly and the lower mold assembly 4, the upper mold assembly 3 and the middle mold assembly form a first film detection cavity 501, and the middle mold assembly and the lower mold assembly 4 form a second film detection cavity 502. In this way, the modular jig 2 of the structure of the embodiment can place two films to be detected for permeation pretreatment at the same time, which can greatly improve the pretreatment efficiency of the film permeation detection pretreatment device. In actual application, it is only necessary to correspondingly set the jig cavity of the film permeation detection pretreatment device to be compatible with the above two or even more kinds of modular jigs 2, so that the modular jig 2 can be connected to the pretreatment gas source through the pretreatment gas path system after being placed in the jig cavity.

[0026] Based on the pretreatment detection principle of the film permeation detection pretreatment device, the film permeation detection pretreatment device can also be set as other pretreatment devices for detecting the sealing performance of containers or bags, as long as the corresponding modular jig 2 is set to be connected to the pretreatment gas source through the pretreatment gas path system after being placed in the jig cavity.

[0027] As a feasible implementation, referring to the drawings, in the embodiment, the jig cavity is a drawer type jig cavity 11 arranged on a plurality of jig drawers 12 of the machine body 1.

The film to be tested can be subjected to the permeation pretreatment by re-closing the jig drawer 12. During the operation of the equipment, the pretreatment gas path system of the equipment is connected to the permeation quality inlet 8 of the module type jig 2.

The permeation quality will permeate from one side of the film to be tested to the other side under the action of a certain concentration difference or pressure. After a certain permeation condition is maintained for a certain period of time, the film to be tested will reach a permeation balance. Since the module type jig 2 of the embodiment is arranged to be common to the film permeation detection pretreatment device and the film permeation rate detection device, the film to be tested can be taken out at any time after the film permeation detection pretreatment device is subjected to the permeation pretreatment to reach the permeation balance and transferred to the film permeation rate detection device for the final permeation rate parameter detection of the film to be tested.
