[0002] Masks are medical supplies that people use frequently in their daily lives, and they are often needed to be carried with them. In order to ensure the convenience of carrying and using such medical supplies, single-piece independent packaging is often used.

After the horizontal push belt motor 124 is started, it drives the gear 126 to rotate. When the gear 126 rotates, it drives the rack 125 to extend or retract, thereby driving the horizontal push plate 121 to extend or retract.

[0076] See also Figure 8 As shown, the bottom pushing part 20 includes a bottom pushing head 21, the top of the bottom pushing head 21 is a plane, the top of the bottom pushing head 21 is located below the horizontal pushing plate 121, and a bottom pushing head 21 is provided below each of the two horizontal pushing plates 121, and the top surface of the bottom pushing head 21 is used to receive the mask conveyed by the conveying mechanism 32.

[0077] The operation process of the mask folding device: the mask completed in the previous process is transported to the top surface of the bottom push-up head 21 through the conveying mechanism 32. At this time, the horizontal push belt motor 124 of the two horizontal push belt mechanisms 12 is started, driving the gear 126 to rotate, and the gear 126 drives the rack 125 to extend when rotating, thereby driving the horizontal push plates 121 of the two horizontal push belt mechanisms 12 to extend to the top surface of the bottom push-up head 21 and the side where the surface of the conveying mechanism 32 is located at the same time, and the two horizontal push plates 121 are close to each other, so that the ear straps on both sides of the mask are pushed to the middle of the mask at the same time, so as to realize the folding of the ear straps of the mask to the middle of the mask. Then, the horizontal push belt motor 124 is started again and drives the gear 126 to rotate in the opposite direction, drives the rack 125 to retract, and conveys the mask with the folded ear straps to the next process through the conveying mechanism 32. The mask folding device provided in the embodiment of the present application has the advantages of high automation, high work efficiency, good folding effect, etc., and can avoid the problem of mask contamination caused by manual touch.

The conveying roller 322 drives the conveying roller to move by rotating, thereby preventing the mask on the mask placement position from moving.

[0079] See also Figure 3-Figure 9 As shown, in the embodiment of the present application, in addition to the horizontal belt pushing mechanism 12, the ear band folding part 10 also includes a vertical belt pressing mechanism 13, and the vertical belt pressing mechanism 13 is used to press creases on the folded ear band.

[0080] See also Fig. 9As shown, the vertical belt pressing mechanism 13 is arranged on the door-shaped frame 11, and the vertical belt pressing mechanism 13 is located above the horizontal belt pushing mechanism 12. The vertical belt pressing mechanism 13 includes an indentation assembly and a vertical belt pressing down assembly, and two indentation assemblies are arranged on the vertical belt pressing down assembly, and the two indentation assemblies are respectively located above the two bottom push-up heads 21. The bottom end of the indentation assembly has two indentation pressure heads 135, and the indentation pressure heads 135 are directly opposite to the top surface of the bottom push-up head 21.

[0081] See also Fig. 9 As shown, the vertical belt pressing down assembly comprises a vertical belt pressing support plate 131, a vertical belt pressing slider 132, a vertical belt pressing rail 133 and a vertical belt pressing cylinder 134. A vertical belt pressing rail 133 is provided on each of the opposite sides of the door-shaped frame 11, a vertical belt pressing slider 132 is slidably arranged on the vertical belt pressing rail 133, and the vertical belt pressing support plate 131 is connected to the vertical belt pressing slider 132.

The vertical belt pressing cylinder 134 is fixed on the door-shaped frame 11, and the vertical belt pressing support plate 131 is connected to the piston rod of the vertical belt pressing cylinder 134.

[0082] See also Figure 8 As shown, the bottom pushing part 20 also includes a bottom pushing cylinder 22 , which is connected to the lower side of the bottom plate 31 , and a piston rod of the bottom pushing cylinder 22 is connected to the bottom end of the bottom pushing head 21 .

[0083] See also Figure 3 As shown, two guide inclined plates 111 are provided on the door-shaped frame 11, and the two guide inclined plates 111 are symmetrically distributed on opposite sides of the conveying mechanism 32. The guide inclined plate 111 includes a guide inclined surface, and the guide inclined surface is inclined downward until a part of the guide inclined surface is located below the material placement surface of the conveying mechanism 32, and the other part of the guide inclined surface is located above the material placement surface of the conveying mechanism 32.

The guide plane 113 is located above the material placement surface of the conveying mechanism 32. The guide plane is flush with the top surface of the bottom push-up head 21 or is located above the top surface of the bottom push-up head 21.

[0084] When the mask is placed on the mask placement position of the conveying mechanism 32, both sides of the mask extend out of the conveyor belt 321 of the conveying mechanism 32. During the conveying process of the conveying mechanism 32, the mask completed in the previous process will contact the guide inclined surface on both sides of the mask, and move upward along the guide inclined surface 112, and move to the guide plane 113, and then move to the top surface of the bottom push-up head 21 through the guide plane 113 and stay. At this time, after the horizontal push belt mechanism 12 performs the operation, the ear straps of the mask are folded toward the middle of the mask. Then, the vertical pressing belt cylinder 134 is started to press the vertical pressing belt support plate 131 downward, and the vertical pressing belt support plate 131 drives the indentation press head 135 to press downward. The four indentation press heads 135 on the two indentation assemblies are just aligned with the four folding positions of the ear straps, thereby pressing folds on the ear straps. In this process, when the vertical pressing cylinder 134 is started, the bottom pushing cylinder 22 can be started to move the bottom pushing head 21 upward, thereby pressing a crease on the ear strap. Because of the existence of the crease, the folded ear strap is not easy to spread out during the subsequent transportation process, and can better maintain the folded state.
