[0002] Existing non-woven fabric production and disinfection equipment, as shown in the Chinese utility model patent "Authorization Announcement No.: CN215840572U; Authorization Publication Date: February 18, 2022; Title: A Medical Non-woven Fabric Production and Disinfection Device," has a sealed door on the front of the disinfection cabinet. Inside the cabinet are correspondingly equipped with a receiving tray, a feed tray, and an ultraviolet irradiation lamp. During use, the sealed door is opened, the non-woven fabric roll is placed horizontally into the disinfection cabinet, and the non-woven fabric on the outer ring of the feed tray is unrolled and connected to the receiving tray. The sealed door is closed, and the ultraviolet irradiation lamp is turned on to disinfect the non-woven fabric. During the disinfection process, the non-woven fabric is gradually unrolled from the feed tray and transferred to the receiving tray. After disinfection is completed, the sealed door is opened and the non-woven fabric roll on the receiving tray is removed.

[0003] During use, the sterilization equipment requires the non-woven fabric roll to be placed in or removed horizontally. This operation is more difficult, time-consuming, labor-intensive, and inconvenient than hoisting or other methods. Furthermore, after the sterilization process for a non-woven fabric roll is completed and the roll is removed from the receiving tray, the worker must remove the non-woven fabric roll support shaft from the feed tray and reassemble it on the receiving tray, which is a cumbersome operation. Summary of the Invention

[0037] How it works: The first conveyor belt 1 delivers the combination of the non-woven fabric roll 51 to be sterilized and the reel 52 to the vicinity of the inlet 211 of the box body 21, and the lifting device 4 lifts the combination of the non-woven fabric roll 51 to be sterilized and the reel 52 above the inlet 212. The worker manually unfolds the non-woven fabric on the non-woven fabric roll 51 to be sterilized and overlaps it on the empty reel 52 below the inlet 211, and then uses the transfer device to transfer the empty reel 52 along the transverse groove 213 to the smooth concave 2131 at the rear end of the transverse groove 213, and simultaneously uses the lifting device 4 to transfer the non-woven fabric roll 51 to be sterilized and the reel 52 to the rear end of the transverse groove 213. 2 is lowered into the smooth concave 2131 at the front end of the transverse groove 213, and then the telescopic cylinder 23 is extended, and the positioning oblique pushing block 241 of the pushing block 24 moves the positioning plug-in 25 into the box body 21 to dock with the end of the reel 52 and axially push the reel 52. At the same time, the positioning plug-in 25 pushes the pushing pin 27 outward through the side connecting rod 28, and the anti-rotation structure at the other end of the reel 52 axially docks with the anti-rotation structure of the inner wall of the sleeve 26 until the end of the reel 52 contacts the stop 261 in the sleeve 26 and stops, thereby realizing the positioning of the two reels 52. Then close the flip cover 215 of the inlet 211 and the outlet 214, light the ultraviolet disinfection lamp 22 and start the drive motor 6 to disinfect the gradually unfolded non-woven fabric. After the disinfection is completed (the pressure strip 522 on the reel 52 at the front end of the transverse groove 213 will automatically pop open under the pulling action of the combination of the non-woven fabric roll 51 and the reel 52 at the rear end of the transverse groove 213, releasing the clamping of the non-woven fabric), turn off the ultraviolet disinfection lamp 22 and the drive motor 6, open the flip cover of the inlet 211 and the outlet 214 215, the telescopic cylinder 23 retracts, the positioning plug-in 25, the side connecting rod 28 and the push pin 27 move synchronously, and the empty reel 52 at the front end of the transverse groove 213 and the combination of the sterilized non-woven fabric roll 51 and the reel 52 at the rear end of the transverse groove 213 are reset, so that the combination of the reel 52 and the non-woven fabric roll 51 and the reel 52 can slide directly in the vertical groove 212 and the transverse groove 213. Finally, the lifting device 4 is used to take out the combination of the sterilized non-woven fabric roll 51 and the reel 52 at the rear end of the transverse groove 213 and lift it to the second conveyor belt 3 for unloading.

[0038] Repeating the above steps can achieve the disinfection of the next non-woven fabric roll 51. The device can easily achieve the disinfection of a heavy non-woven fabric roll 51, with low labor intensity for workers and high disinfection efficiency.
