For example, existing dry-wet separation packaging bags store cleansing towels in the dry area and liquid in the wet area. The dry area and the wet area are separated by spacer seals and dividing strips. If you want to move the liquid in the wet area to the dry area to cause the cleansing towel to absorb the liquid, you must squeeze the wet area hard so that the liquid in the wet area can expand the dividing strip and cause the liquid to flow to the dry area, which is laborious to operate. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art:

[0005] In the existing packaging bag, when the liquid in the wet area is moved to the dry area, the wet area must be squeezed hard so that the liquid in the wet area can expand the dividing strip and promote the liquid to flow to the dry area, which is laborious.

[0018] Beneficial effects of the present invention:

[0019] 1. When the packaging bag body is in use, the mask paper is sealed in the dry area, and the essence is sealed in the wet area. When in use, first separate the dry area containing the mask paper from the packaging bag body through tearing edge 1. During this process, the user's fingers are pinched on the outer surfaces on both sides of the dry area, so the mask paper in the dry area will not fall off. After the dry area containing the mask paper is separated from the packaging bag body, tearing edge 2 is used to tear off the entire hot-pressed separation part, so that the upper end of the wet area is open, and then pour the mask paper in the dry area into the wet area, so that the mask paper absorbs the essence, and the whole process is labor-saving.

[0020] 2. When the packaging bag body is in use, the dry area and the wet area can also be folded in half with the hot-pressed partition as the horizontal center line. At this time, the dry area is flipped and attached to one side of the wet area. At this time, the tearing notch 1 on the dry area is flush with the tearing notch 2 on the wet area. Then the user can tear off the hot-pressed partition located between the dry area and the wet area through the tearing notch 1 (or the tearing notch 2). At this time, the end of the dry area close to the hot-pressed partition is open, and the end of the wet area close to the hot-pressed partition is also open, so that the dry area and the wet area can be opened at the same time, which is more convenient to operate.

[0021] 3. In the initial state, the upper mounting plate 2 is at a position far away from the lower mounting plate 2. At this time, the elastic airbag is in an unsqueezed state. When the upper mounting plate 2 brings the upper special-shaped cutting knife to quickly approach the lower mounting plate 2, the elastic airbag will be squeezed and contracted, and the excess air in the elastic airbag is discharged through the one-way air outlet valve and the air outlet pipe, generating an air flow, which just blows the waste cut by the upper special-shaped cutting knife and the lower special-shaped cutting knife downward, causing the cut debris to fall into the mesh frame, avoiding the cut debris from being stuck on the inner surface of the upper special-shaped cutting knife, and moving upward with the upper special-shaped cutting knife and the upper mounting plate 2, and falling onto the surface of the plastic film.

[0022] 4. When the upper mounting plate 2 with the upper special-shaped cutting knife quickly approaches the lower mounting plate 2, it will drive the L-shaped connecting plate and the lifting plate to move downward quickly. In the process of the lifting plate moving downward, an air flow will be generated on the side of the lifting plate close to the handle, thereby driving the cut pieces to move toward the handle inside the mesh frame until the cut pieces are accumulated in the mesh frame on the side close to the handle to form an inclined surface. The subsequent cut pieces that fall down will fill the mesh frame along the inclined surface until a certain amount of cut pieces are accumulated under the lifting plate. When the lifting plate moves downward, it will compress the cut pieces located below. At this time, the pressure sensor is acted upon by the reverse force and generates an electrical signal, prompting the upper mounting plate 2 to stop moving up and down, reminding the staff that the mesh frame is full.

[0034] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0035] Reference Figure 1-Figure 10 A cosmetic dry-wet separation packaging bag includes a packaging bag body 38, on which a hot-pressing partition 39 is provided, and the packaging bag body 38 is divided into a dry area 40 and a wet area 41 by the hot-pressing partition 39. The sealing edge of the dry area 40 is symmetrically provided with two tearing notches 42 near the hot-pressing partition 39, and the sealing edge of the wet area 41 is symmetrically provided with two tearing notches 43 near the hot-pressing partition 39.

[0036] Reference Figure 1When the packaging bag body 38 is in use, the facial mask paper is sealed in the dry area 40, and the essence is sealed in the wet area 41. When in use, the dry area 40 containing the facial mask paper is first separated from the packaging bag body 38 through the tearing edge 1 42. During this process, the user's fingers are pinched on the outer surfaces of both sides of the dry area 40, so the facial mask paper in the dry area 40 will not fall off. When the dry area 40 containing the facial mask paper is separated from the packaging bag body 38, the entire hot-pressed separation part 39 is torn off through the tearing edge 2 43, so that the upper end of the wet area 41 is open, and then the facial mask paper in the dry area 40 is poured into the wet area 41, so that the facial mask paper absorbs the essence, and the whole process is labor-saving.

[0037] In other embodiments, when the packaging bag body 38 is in use, the dry area 40 and the wet area 41 can also be folded in half with the hot-pressed partition 39 as the horizontal center line. At this time, the dry area 40 is flipped and attached to one side of the wet area 41. At this time, the tear 1 42 on the dry area 40 is flush with the tear 2 43 on the wet area 41. Then the user can tear off the hot-pressed partition 39 located between the dry area 40 and the wet area 41 through the tear 1 42 (or the tear 2 43). At this time, the end of the dry area 40 close to the hot-pressed partition 39 is open, and the end of the wet area 41 close to the hot-pressed partition 39 is also open, thereby achieving the simultaneous opening of the dry area 40 and the wet area 41.

Then, when the plastic film 3 passes through the intermediate hot pressing assembly, the middle sections of the upper and lower layers of plastic film 3 are fixed together to form a hot pressing partition 39. Then, when passing through the tear forming assembly, two tearing notches 42 and two tearing notches 43 are formed at the edge sealing positions on both sides of the plastic film 3. When passing through the cutting assembly, the plastic film 3 is cut and then continued to be guided by the second conveying rollers 5. At this time, the packaging bag body 38 is initially formed, but the two ends of the packaging bag body 38 are not edge sealed. Then, the initially formed packaging bag body 38 is sequentially placed and edge sealed with facial mask paper, and filled and edge sealed with essence liquid through existing equipment (the packaging of facial mask paper and essence liquid is the existing technology and will not be described in detail in the present invention) to form a complete cosmetic product, which includes the packaging bag body 38, facial mask paper and essence liquid.

The cut pieces that fall down subsequently will fill the mesh frame 17 along the inclined surface until a certain amount of cut pieces are accumulated under the lifting plate 27. When the lifting plate 27 moves downward, it will compress the cut pieces located below. At this time, the pressure sensor 28 is acted upon by the reverse force and generates an electrical signal, prompting the upper mounting plate 212 to stop moving up and down, reminding the staff that the mesh frame 17 is full.

When the upper mounting plate 12 brings the upper special-shaped cutting knife 13 to quickly approach the lower mounting plate 14, the elastic airbag 20 will be squeezed and contracted, and the excess air in the elastic airbag 20 is discharged through the one-way air outlet valve 22 and the air outlet pipe 23, generating an air flow, which just blows the waste cut by the upper special-shaped cutting knife 13 and the lower special-shaped cutting knife 15 downward, causing the cut debris to fall into the mesh frame 17, avoiding the cut debris from being stuck on the inner surface of the upper special-shaped cutting knife 13, and moving upward with the upper special-shaped cutting knife 13 and the upper mounting plate 12, and falling onto the surface of the plastic film 3;

[0060] Reference Figure 5-Figure 8 When the upper mounting plate 212 brings the upper special-shaped cutting knife 13 to quickly approach the lower mounting plate 214, it will drive the L-shaped connecting plate 26 and the lifting plate 27 to move downward quickly. In the process of the lifting plate 27 moving downward, an air flow will be generated on the side of the lifting plate 21 close to the handle 18, thereby driving the cut pieces to move toward the handle 18 inside the mesh frame 17 until the cut pieces are accumulated in the mesh frame 17 on the side close to the handle 18 to form an inclined surface. The cut pieces that fall down subsequently will fill the mesh frame 17 along the inclined surface until a certain amount of cut pieces are accumulated under the lifting plate 27. When the lifting plate 21 moves downward, it will compress the cut pieces located below. At this time, the pressure sensor 28 is acted upon by the reverse force and generates an electrical signal, prompting the upper mounting plate 212 to stop moving up and down, reminding the staff that the mesh frame 17 is full.
