Further, the lengths of upper soft magnetic strip 44 and lower soft magnetic strip 45 may be further adjusted to accommodate different sizes of medical packaging bags.

Initial position: the detection roller 16 is located at the lower end of the incoming side but does not contact the drive belt 10. The clamp spring 29 is not stressed, and the upper clamp 30 and the lower clamp 41 are propped and fixed. The upper soft magnetic strip 44 is hung on the upper part by the magnetic strip belt 43 and is not contacted with the lower soft magnetic strip 45. The bayonet check plate 48 closes the front air duct 13, and the sealing check plate 51 closes the front air duct 13. The conjoined round-head sliding block 53 is ejected by the one-way spring 56, one end of the conjoined round-head sliding block 53 is clamped into the bayonet one-way plate 48, and the sealing one-way plate 51 is propped against the other end of the conjoined round-head sliding block 53.

The detection and disinfection method of the medical packaging bag comprises the following specific steps:

the first step is as follows: the packaging bag is clamped. The clamp motor 40 is started to drive the screw rod 32 to rotate, the rotation of the screw rod 32 causes the nut 34 to generate downward displacement, the downward movement force of the nut 34 is transmitted to the upper clamp 30 through the nut spindle 31, the upper clamp 30 rotates around the clamp spindle 28 against the elastic force of the clamp spring 29 to open the working surfaces of the upper clamp 30 and the lower clamp 41, the opening portion of the packaging bag is transmitted to the position of the lower clamp 41 by the conveyor belt 10, the clamp motor 40 rotates reversely to drive the screw rod 32 to rotate reversely, the reverse rotation of the screw rod 32 causes the upward displacement of the nut 34, the upward movement force of the nut 34 is transmitted to the upper clamp 30 through the nut spindle 31, the elastic force of the clamp spring 29 and the upward movement force of the nut 34 push the upper clamp 30 to rotate around the clamp spindle 28, the working surfaces of the upper clamp 30 and the lower clamp 41 are closed, the two ends of the opening portion of the packaging bag are clamped, in the process, the end gas pipe 25 is inserted into the opening portion of the packaging bag.

The second step is that: the opening is sealed. The gear motor is started to drive the driving conical gear 37 to rotate, the driving conical gear 37 rotates to drive the driven conical gear 36, the driven conical gear 36 rotates to drive the upper rotating shaft 35 to rotate, the upper rotating shaft 35 rotates to drive the upper roller 42 to rotate, the magnetic stripe belt 43 drives the upper soft magnetic stripe 44 to be put down through the rotation of the upper roller 42, and the upper soft magnetic stripe 44 and the lower soft magnetic stripe 45 are continuously close to each other. Finally, the magnetic force is used for adsorbing the opening parts of the packaging bags together, so that the opening parts of the packaging bags are closed.

The third step: gas was blown in and airtightness was checked. The disinfection gas sent from the front gas pipe 13 can not enter the gas outlet pipe 15 because the sealing one-way plate 51, the bayonet one-way plate 48 and the connected round-head slider 53 are arranged in a linkage way, and only can enter the medical packaging bag through the middle gas pipe 24 and the tail gas pipe 25, so that the packaging bag starts to inflate and expand, and drives the detection rotary drum 16 on which the negative pressure is exerted to start to move upwards. If the air tightness is good, the target position can be reached, the detection rotary drum 16 is turned to the other side of the detection rotary drum 20, and if the air tightness is unqualified, the detection rotary drum 16 cannot be driven to reach the target position to be turned.

The fourth step: and detecting the structural strength. And stopping blowing, wherein the packaging bag is in an expansion state and is in a simulated use state. The detection motor 22 is started to drive the detection belt 21 to start rotating, and the detection drum 16 starts moving downwards to apply pressure to the expanded packaging bag because the detection drum 16 is fixedly arranged on the detection belt 21. When the set time is up, the detection motor 22 stops rotating.

The fifth step: and (5) exhausting and sterilizing. When the detection motor 22 is stopped, the impeller motor 14 is started and drives the impeller 50 to rotate, so as to pump out the sterilizing gas in the packaging bag. Because the sealing one-way plate 51, the bayonet one-way plate 48 and the conjoined round-head slider 53 are arranged in a linkage manner, gas enters the gas outlet pipe 15 and is sprayed out from the gas outlet hole 26, and the exterior of the packaging bag and the detection device are disinfected.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
