DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-3 As shown, the present invention discloses a wet compress cotton single-pack spacer sheet packaging structure, comprising a plurality of cotton sheets 11 in a folded state, wherein the cotton sheets 11 include open cotton sheets 12 with cutouts 2 and open cotton sheets 13 without cutouts 2; during packaging, the open cotton sheets 12 and the open cotton sheets 13 are alternately stacked and arranged; Specifically, Figure 1 As shown, from a top view, the cotton piece 11 is in a "V" shape in a folded state, and a side opening 21 is provided on the cotton piece 11. When the open cotton 12 and the non-opening cotton 13 are alternately stacked, the side openings 21 of the open cotton 12 and the non-opening cotton 13 are both arranged facing the same side.

[0028] Specifically, the cotton sheet 11 is a stretchable non-woven fabric, which is popular among consumers due to its advantages such as light weight, softness, water repellency and breathability, non-toxicity and non-irritation, antibacterial and chemical resistance, environmental protection and durability. At the same time, non-woven fabric is also often used as the main material for wet compress cotton. The cotton sheet 11 is provided with a fold line 111 and a fold line 112. When packaging, the cotton sheet 11 is folded in sequence according to the fold line 111 and the fold line 112 to form a folded cotton sheet 11; accordingly, the folded cotton sheet 11 is unfolded in sequence according to the fold line 112 and the fold line 111 to obtain the unfolded cotton sheet 11; it should be noted that both the open cotton sheet 12 and the open cotton sheet 13 are provided with the fold line 111 and the fold line 112; By setting the fold line 111, the fold line 112 and the folding state, the larger cotton sheet 11 can be folded into a smaller volume, so as to facilitate packaging and storage, thereby increasing the number of the cotton sheets 11 in each packaging structure, so as to reduce the consumption cost of consumers; Furthermore, if Figure 2As shown, the extension direction of the incision 2 on the open cotton 12 in the unfolded state is consistent with the stretchable direction of the open cotton 12 in the unfolded state. When in use, after the consumer unfolds the open cotton 12, the incision 2 is stretched accordingly by stretching it along the stretchable direction of the open cotton 12, so that the gap distance of the incision 2 is adapted to the consumer's mouth or nose, thereby improving the consumer's usage experience.

[0029] Specifically, Figure 3 As shown, the cotton pieces 11 and the open cotton 12 and the open cotton 13 are alternately stacked and arranged, and are all formed by a larger cloth roll 1 through an automatic mechanical integrated folding and cutting operation; during manufacturing, the cloth roll 1 is first transmitted to a cutting mechanism 4 to cut the cloth roll 1 to form the incision 2; then it is transmitted to a folding mechanism 3 to form a fold line 111 on the cloth roll 1 and fold along the fold line 111; then, the cloth roll 1 is formed into a fold line 112 by a folding mechanism 5 and folded along the fold line 112, and finally, the cloth roll 1 in the folded state is cut along the central axis P by a cutting mechanism 6, so as to obtain the open cotton 12 and the open cotton 13 alternately stacked and arranged; during packaging, the worker only needs to select a certain amount of the open cotton 12 and the open cotton 13 alternately stacked and arranged for packaging; It should be noted that, under the same effect, the cutting step of the cutting mechanism 1 4 and the folding step of the folding mechanism 1 3 can be interchanged, that is, the settings of the two mechanisms can be interchanged without affecting the actual production effect; Furthermore, if Figure 4 As shown, the incision 2 on the open cotton 12 is formed by cutting the cloth roll 1 into the cotton pieces 11 by the cutting mechanism 4, and the cutting mechanism 4 includes two main cutting wheels 41 and a secondary cutting wheel 42 symmetrically arranged up and down, and the cloth roll 1 is arranged between the main cutting wheel 41 and the secondary cutting wheel 42, wherein at least one cutting knife 411 is arranged on the main cutting wheel 41, and an auxiliary knife 421 is arranged on the secondary cutting wheel 42, and the cutting knife 411 and the auxiliary knife 421 are arranged in corresponding positions; During cutting, the main cutting wheel 41 rotates, while the secondary cutting wheel 42 does not rotate, and the secondary knife 421 of the secondary cutting wheel 42 always faces the main cutting wheel 41; the main cutting wheel 41 rotates, so that the cutting knife 411 on the main cutting wheel 41 and the secondary knife 421 rub against each other, so as to cut the cloth roll 1 passing through the main cutting wheel 41 and the secondary cutting wheel 42 to form the incision 2; after the cutting is completed, the cloth roll 1 is transmitted to the folding mechanism 1 3 to be folded along the folding line 111; Furthermore, if Figure 5As shown, the folding mechanism 1 3 includes a guide plate 31 with a triangular structure and two symmetrically arranged pressing rollers 32, the guide plate 31 is provided with a sharp corner 311 and two guide edges 312 adjacent to the sharp corner 311, the two pressing rollers 32 are arranged on a side close to the sharp corner 311 in the guide plate 31, and when in use, the cloth roll 1 in the unfolded state is covered on the guide plate 31 and is driven to pass through the two pressing rollers 32; when driving, the two sides of the cloth roll 1 are driven along the guide edges 312 respectively, and under the top action of the sharp corner 311, the cloth roll 1 located at the guide edges 312 is folded with each other, and at this time, the sharp corner 311 corresponds to the fold line 1 111; then, when driving between the pressing rollers 32, the cloth roll 1 in the folded state is tightly folded under the squeezing action of the two pressing rollers 32, so as to facilitate the subsequent folding operation of the folding mechanism 2 5; Furthermore, the guide plate 31 is placed obliquely so that the horizontal height of the sharp corner 311 is higher than the end of the guide edge 312 away from the sharp corner 311; Preferably, the transmission direction of the cloth roll 1 on the guide plate 31 and the transmission direction of the cloth roll 1 between the two pressing rollers 32 are arranged alternately, so that when the cloth roll 1 is transmitted from the guide plate 31 to the pressing rollers 32, the cloth roll 1 between the pressing rollers 32 forms a bending portion 15, and under the action of the transmission tension, the folding fit between the cloth roll 1 and the pressing rollers 32 is effectively improved, thereby improving the folding effect of the cloth roll 1 along the folding line 111; Furthermore, if Figure 6 As shown, the folding mechanism 2 5 includes two symmetrically arranged folding wheels 51, and the cloth roll 1 is arranged between the two folding wheels 51. Under the rotation of the folding wheels 51, a folding portion 14 of a continuous "W"-shaped folding structure of the cloth roll 1 can be formed; It should be noted that the folding wheel 51 that enables the cloth roll 1 to form a continuous folding portion 14 is a prior art and will not be elaborated in detail herein; Furthermore, in the "W"-shaped folding state, the length of each folding portion 14 on the cloth roll 1 is equal to the distance that the cloth roll 1 is driven when the main cutting wheel 41 rotates one circle; that is, when the main cutting wheel 41 rotates one circle, the transmission part of the cloth roll 1 by the main cutting wheel 41 just forms the folding portion 14; Among them, Figure 7 As shown, the folding portion 14 includes a folding edge 141, a folding edge 142, a folding edge 143, a folding edge 144, a folding edge 145, a folding edge 146, a folding edge 147 and a folding edge 148 which are connected in sequence; It should be noted that, during cutting, the rotation speed of the main cutting wheel 41 cooperates with the transmission speed of the cloth roll 1, but the rotation speed of the main cutting wheel 41 is not limited by the transmission speed of the cloth roll 1; when the transmission speed of the cloth roll 1 remains unchanged, the position of the incision 2 of the folding portion 14 can be adjusted by changing the rotation speed of the main cutting wheel 41, and the number of the incisions 2 of the folding portion 14 can be increased by increasing the number of the cutters 411; Therefore, it is only necessary to ensure that when the cloth roll 1 is cut, the rotation and cutting of the main cutting wheel 41 can form one to three incisions 2 on one folding portion 14 to achieve the alternating stacking arrangement of the open cotton 12 and the open cotton 13; and in this embodiment, the length of each folding portion 14 on the cloth roll 1 is equal to the transmission distance of the cloth roll 1 corresponding to one rotation of the main cutting wheel 41; Furthermore, if Figure 6 As shown, the cutting mechanism 2 6 includes a longitudinal knife 61, and the cloth roll 1 after passing through the folding mechanism 2 5 is cut along the central axis P by the longitudinal knife 61 to obtain two groups of folded cotton pieces 11 located on both sides of the central axis P, and at least one group of the cotton pieces 11 includes the open cotton 12 and the open cotton 13 alternately stacked and arranged. In the first embodiment, Figure 8 As shown, the main cutting wheel 41 is provided with only one cutter 411, and the incision 2 formed by the cutter 411 is located in the folding edge 142 of each folding portion 14; After the cutting action of the second cutting mechanism 6, the second fold 142 and the third fold 143 are located on the left side of the central axis P to form the open cotton 12, and the sixth fold 146 and the seventh fold 147 are formed to form the closed cotton 13; Located on the right side of the central axis P, the folded edge 4 144 and the folded edge 5 145 form the non-opening cotton 13, and the folded edge 8 148 and the folded edge 1 141 in the next folded portion 14 form the non-opening cotton 13; That is to say, in a group of cotton pieces 11 located on the left side of the central axis P, the open cotton pieces 12 and the open cotton pieces 13 are alternately stacked and arranged; and in a group of cotton pieces 11 located on the right side of the central axis P, all of them are the open cotton pieces 13; therefore, by providing a cutting knife 411 on the main cutting wheel 41, when the cotton pieces 11 are packaged, the two groups of cotton pieces 11 of different types located on the left and right sides of the central axis P can be separately packaged, thereby increasing the diversity of choices for consumers; In the second embodiment, Figure 4As shown in FIG. 9 , the main cutting wheel 41 is provided with two cutting knives 411. From a top view, the extension directions of the two cutting knives 411 are perpendicular to each other. When cutting, the incisions 2 formed by the cutting knives 411 are respectively located in the folding edge 2 142 and the folding edge 4 144 in the same folding portion 14. After the cutting action of the second cutting mechanism 6, the second fold 142 and the third fold 143 are located on the left side of the central axis P to form the open cotton 12, and the sixth fold 146 and the seventh fold 147 are formed to form the closed cotton 13; Located on the right side of the central axis P, the folded edge 4 144 and the folded edge 5 145 form the open cotton 12, and the folded edge 8 148 and the folded edge 1 141 in the next folded portion 14 form the open cotton 13; That is to say, at this time, the two groups of cotton pieces 11 located on the left and right sides of the central axis P respectively are composed of the open cotton 12 and the non-opening cotton 13 that are alternately stacked. Therefore, by arranging two cutting knives 411 on the main cutting wheel 41, the production efficiency of the combination of cotton pieces 11 composed of the open cotton 12 and the non-opening cotton 13 that are alternately stacked can be effectively improved when the cotton pieces 11 are packaged.

[0030] In the third embodiment, Fig.10 As shown, four knife positions (not shown) are formed equidistantly around the rotation axis of the main cutting wheel 41, wherein the cutters 411 are arranged in three of the knife positions, that is, the main cutting wheel 41 is provided with three cutters 411; during cutting, the incisions 2 formed by the cutters 411 are respectively located in the folding edge 2 142, the folding edge 4 144 and the folding edge 8 148 in the same folding portion 14; After the cutting action of the second cutting mechanism 6, the second fold 142 and the third fold 143 are located on the left side of the central axis P to form the open cotton 12, and the sixth fold 146 and the seventh fold 147 are formed to form the closed cotton 13; Located on the right side of the central axis P, the folded edge 4 144 and the folded edge 5 145 form the open cotton 12, and the folded edge 8 148 and the folded edge 1 141 in the next folded portion 14 form the open cotton 12; That is to say, at this time, in a group of cotton pieces 11 located on the left side of the central axis P, the open cotton 12 and the non-open cotton 13 are alternately stacked and arranged; and the group of cotton pieces 11 located on the right side of the central axis P are all the open cotton 12; therefore, by arranging three cutting knives 411 on the main cutting wheel 41, when the cotton pieces 11 are packaged, the two groups of cotton pieces 11 with different structures located on the left and right sides of the central axis P can be separately packaged, which can also increase the diversity of consumers' choices.

[0031] The working principle of the present invention is described in detail below; During manufacturing, the cloth roll 1 is transmitted to the cutting mechanism 1 4 to cut the cloth roll 1 to obtain the incision 2, and then transmitted to the folding mechanism 1 3 to be folded along the folding line 111, and then folded along the folding line 112 by the folding mechanism 2 5, and finally the cloth roll 1 in the folded state is cut along the central axis P by the cutting mechanism 2 6, so as to obtain at least one group of cotton pieces 11 composed of the open cotton 12 and the open cotton 13 alternately stacked on each other.

[0032] The innovation of the present invention lies in that open-end cotton and non-opening cotton are stacked alternately in a package, so that when consumers apply a wet compress to their face, they can use wet compress cotton of different structures on different facial parts, thereby improving consumers' convenience and user experience; at the same time, by adopting a mechanical integration method to automatically cut and fold the cloth roll to form a packaging structure in which open-end cotton and non-opening cotton are stacked alternately, thereby effectively improving the production efficiency of the cotton sheet group in which open-end cotton and non-opening cotton are stacked alternately and reducing its production cost.
