Detailed Description

Referring to fig. 1 to 3, the present invention includes a frame 1, a transfer screw 2, and a first driving device 3; the conveying screw rod 2 is in a dumbbell shape with large diameters at two ends and small diameter in the middle; the two ends of the part with the small middle diameter of the transmission screw rod 2 are rotary connecting parts; two open supports 4 are fixedly arranged on the frame 1; the two opening supports 4 are respectively positioned at the two ends of the part with the small diameter in the middle of the conveying screw rod 2; the opening support 4 is provided with an opening hole, and the diameter of the opening hole is smaller than the diameter of the two ends of the conveying screw rod 2. The rotary connection of the transfer screw 2 is rotatably connected with the opening hole of the opening support 4. The diameter of the opening hole is smaller than the diameter of the two ends of the conveying screw rod 2; the limitation of the two open supports 4 is such that the feed screw 2 can only be rotated relative to the open supports 4 and cannot move axially.

The first driving means 3 comprises a first driving motor 31; the first driving motor 31 is fixed on the frame 1; a driving friction wheel 32 is rotatably arranged on the frame 1; an output shaft of the first driving motor 31 is in transmission connection with an output wheel, and the output wheel is in transmission connection with a driving friction wheel 32 through a belt; the driving friction wheel 32 forms static friction with the large-diameter surface of the conveying screw 2.

One end of the conveying screw rod 2 is a feeding end, and the other end is a discharging end; the thread groove of the conveying screw rod 2 is a conveying groove for hanging a lug line of the mask; the opening of the opening hole is positioned right below the opening hole and is used for the suspension loop wire to pass through.

The feed end of the conveying screw rod 2 is provided with a guide device 5 for guiding the suspension loop wire to enter the thread groove; the guide device 5 comprises a guide slideway 51, a sleeve 52 and an overturn-preventing gravity thallium 53; the sleeve 52 is rotatably arranged at the feeding end of the conveying screw rod 2; the guide slideway 31 and the overturn-preventing gravity thallium 53 are oppositely arranged on the side wall of the sleeve 52; the overturn-preventing gravity thallium 53 is heavier than the guide slideway 51; the guide slide 51 is used to guide the ear wire along it into the threaded groove.

The rack 1 is also provided with two suspension loop wire guide plates 6 which are symmetrically arranged and extend along the conveying direction; the two suspension loop wire guide plates 6 are positioned at two sides of the conveying screw rod 2; the suspension loop wire guide plate 6 is provided with a guide part which is opened outwards and is positioned at the feed end of the conveying screw rod.
