Description

Technical Field

[0001] The invention belongs to the technical field of wet compress cotton, and in particular relates to an opening method of wet compress cotton. Background Art

[0002] Wet compress cotton is a cotton material used for skin care. It is usually made of spunlace non-woven fabric and has good water release and absorption. When using, lotion or toner is usually poured into or soaked in the wet compress cotton to allow it to fully absorb water, and then the wet compress cotton is evenly applied to the face to achieve the effects of moisturizing, calming, softening the stratum corneum, and promoting the absorption of subsequent skin care products.

[0003] In actual use, people have found that wet compresses will cover the nose and mouth, causing breathing difficulties and affecting the skin care experience. Therefore, people need to cut at least one opening on the wet compress themselves. When using the wet compress to apply to the face, the part that needs to breathe is aligned with the opening, thereby improving the comfort of use. However, using wet compresses to apply to the face is a skin care method that people use frequently in daily life. Each time they use it, they need to cut an opening themselves, which greatly reduces people's user experience. Summary of the invention

[0012] Furthermore, there are three cutters, two of which are symmetrically arranged at 180 degrees to each other, and the other cutter is arranged in the middle position between the two symmetrically arranged cutters. The rotation speed of the driving wheel is consistent with the transmission speed of the cloth, so that the cotton pieces with incisions and the cotton pieces without incisions in one cotton group are alternately arranged, and the cotton pieces in the other cotton group all form the incisions.

[0013] Furthermore, two cutters are provided and are arranged at 90 degrees to each other, and the rotation speed of the driving wheel is consistent with the transmission speed of the cloth, so that the cotton pieces with incisions and the cotton pieces without incisions in the two cotton groups are staggered.

DETAILED DESCRIPTION

[0030] 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.

[0031] like Figure 1-6 As shown, the present invention discloses an opening method for wet compress cotton, comprising a cloth 1, an opening mechanism 2, a folding mechanism 3, a folding mechanism 4 and a cutting mechanism 5. The cloth 1 is formed into an independent cotton piece 6 with a cut 61 through the opening process of the opening mechanism 2, the folding process of the folding mechanism 3, the folding process of the folding mechanism 4 and the cutting process of the cutting mechanism 5. The cotton piece 6 is a wet compress cotton; The specific steps are as follows: Step 1: First, the cloth 1 is respectively transmitted to the opening mechanism 2 and the folding mechanism 3, and the cutter 211 in the opening mechanism 2 is used to open the cloth 1 and form the incision 61, and the folding mechanism 3 is used to fold the cloth 1 in a "V" shape in the width direction; Step 2: The folded and opened cloth 1 is then transferred to the folding mechanism 4, and the folding mechanism 4 is used to perform a "W"-shaped folding process on the cloth 1 in the length direction; Step 3: Finally, the "W"-shaped cloth 1 is transmitted to the cutting mechanism 5 for cutting operation, so that the cloth 1 is divided into two cotton groups 7 arranged in parallel, each of which is composed of a plurality of cotton sheets 6 stacked on each other; In at least one of the cotton groups 7 , the cotton pieces 6 with the cutouts 61 and the cotton pieces 6 without the cutouts 61 are arranged alternately or all of the cotton pieces 6 have the cutouts 61 and are stacked in sequence.

[0032] Specifically, the opening mechanism 2 in step 1 further includes a driving wheel 21 and an auxiliary wheel 22 symmetrically arranged with each other, the cloth 1 is passed through the driving wheel 21 and the auxiliary wheel 22, the driving wheel 21 and the auxiliary wheel 22 can be arranged horizontally up and down and clamp the cloth 1 up and down (i.e., horizontal arrangement), or they can be respectively located on the left and right sides of the cloth 1 and the length direction of the driving wheel 21 and the auxiliary wheel 22 is arranged perpendicular to the horizontal plane (i.e., vertical arrangement); at the same time, the cutting knife 211 is arranged on the outer peripheral wall of the driving wheel 21 and along the driving wheel 21 The auxiliary wheel 22 is arranged in the direction of the rotation axis, and an auxiliary knife 221 used in conjunction with the cutter 211 is fixedly arranged on the auxiliary wheel 22; when in use, the auxiliary wheel 22 does not rotate and the auxiliary knife 221 faces the driving wheel 21, and the driving wheel 21 rotates and drives the cutter 211 to continuously approach and move away from the auxiliary knife 221, thereby realizing an opening process for the cloth 1 arranged between the cutter 211 and the auxiliary knife 221, so that the incision 61 is formed on the cloth 1, and the incision 61 extends along the width direction of the cloth 1 and is located in the middle of the cloth 1; Further, the folding mechanism 3 includes a guide plate 31 of a triangular structure, and the guide plate 31 is provided with a hypotenuse 1 32, a hypotenuse 2 33 and a vertex 34 located between the hypotenuse 1 32 and the hypotenuse 2 33. When in use, the vertex 34 in the guide plate 31 faces the folding mechanism 4, and the guide plate 31 is designed to be inclined so that the vertex 34 is lifted up, and the cloth 1 is slidably connected to the top surface of the guide plate 31. Due to the inclined design of the guide plate 31, the cloth 1 is folded when it slides to the hypotenuse 1 32, the hypotenuse 2 33 and the vertex 34, and a crease 1 63 is formed. The crease 1 63 extends along the length direction of the cloth 1 and is perpendicular to the extension direction of the incision 61. The vertex 34 is connected to the bottom of the crease 1 63, thereby realizing a "V"-shaped folding process of the cloth 1, that is, a folding process along its width direction; It should be noted that the setting positions and processing sequences of the opening mechanism 2 and the folding mechanism 3 are interchangeable, that is, the opening process can be performed first and then the folding process, or the folding process can be performed first and then the opening process, which does not affect the actual production effect.

[0033] Specifically, the folding mechanism 4 includes two longitudinally arranged (vertically arranged) guide wheels 41, and the cloth 1 after folding and opening is passed between the two guide wheels 41. When in use, the cloth 1 is continuously bent left and right to form a "W"-shaped and continuous bending portion 11 through the rotation cooperation and steering switching of the two guide wheels 41. The bending portion 11 includes a folded edge 111, a folded edge 112, a folded edge 113, a folded edge 114, a folded edge 115, a folded edge 116, a folded edge 117 and a folded edge 118 in sequence. The incision 61 is located in any folded edge of the bending portion 11, and the connection between adjacent folded edges is folded to form a crease 2 64.

[0034] In the present method, when the rotation speed of the driving wheel 21 is the same as the transmission speed of the cloth 1, the driving wheel 21 rotates one circle, and the cloth 1 located at the folding mechanism 4 just forms one of the bending portions 11; when the rotation speed of the driving wheel 21 is twice the transmission speed of the cloth 1, the driving wheel 21 rotates two circles, and the cloth 1 located at the folding mechanism 4 just forms one of the bending portions 11; in actual operation, the rotation speed of the driving wheel 21 can be adjusted to match the bending portion 11, and the above two speed adjustments are only required to illustrate the technical solution of the present method, and are not intended to limit the scope of protection of the present invention; In the present method, the number and position of the cutters 211 and the rotation speed of the driving wheel 21 are changed, so as to achieve the purpose of arranging the cotton pieces 6 with the cutouts 61 and the cotton pieces 6 without the cutouts 61 in each cotton group 7 in different orders, and the cotton pieces 6 with the cutouts 61 and the cotton pieces 6 without the cutouts 61 in at least one cotton group 7 are arranged alternately or are all the cotton pieces 6 with the cutouts 61 and are stacked in order, thereby solving the problem in the prior art that the finished wet compress cotton is not provided with the cutouts 61, resulting in a poor user experience for consumers. Furthermore, the cutting mechanism 5 includes a dividing knife 51, and the dividing knife 51 is arranged on the central axis P of the bending portion 11. When the cloth 1 continuously forms the bending portion 11 and continues to be transmitted, the bending portion 11 is cut by the dividing knife 51 to form two cotton groups 7, and each cotton group 7 is composed of independent cotton pieces 6 stacked together; when the workers pack the cotton pieces 6, they only need to put the cotton group 7 of a specified length into a packaging box or bag to complete the packaging.

[0035] Specifically, the bending portion 11 is cut into two cotton groups 7 under the cutting action of the cutting mechanism 5, and a side opening 62 is formed on the cotton sheet 6 in each cotton group 7, and the side openings 62 in the cotton sheets 6 in the two cotton groups 7 are arranged opposite to each other; the side openings 62 are arranged to facilitate consumers to take and extract the cotton sheet 6; In actual use, after the consumer pulls out the cotton piece 6 from the cotton group 7, it can be unfolded along the second fold 64 and the first fold 63 in sequence. The cotton piece 6 in the unfolded state can be stretched along the direction of the second fold 64 to facilitate adaptation to the consumer's face.

[0036] In order to more clearly and in detail illustrate the technical solution of the present method, the present invention lists but is not limited to the following embodiments; In the first embodiment, if Figure 7 As shown, two cutters 211 are provided and are symmetrically arranged at 180 degrees to each other.

At this time, the incision 61 is located in the folding edge 111, the folding edge 113, the folding edge 115 and the folding edge 117. After cutting by the cutting mechanism 5, the cotton group 7 located on the left and right sides of the central axis P is composed of cotton pieces 6 with the incision 61 stacked in sequence.

[0039] In the fourth embodiment, if Fig.10As shown, two cutters 211 are provided and are symmetrically arranged at 180 degrees to each other. The rotation speed of the driving wheel 21 is twice the transmission speed of the cloth 1. The driving wheel 21 rotates twice to form a bending portion 11. At this time, the incision 61 is located in the folding edge 111, the folding edge 113, the folding edge 115 and the folding edge 117. After cutting by the cutting mechanism 5, the cotton group 7 located on the left and right sides of the central axis P is composed of cotton pieces 6 with the incision 61 stacked in sequence, and has the same effect as the incision 61 in the third embodiment.

[0040] In the fifth embodiment, if Fig.11 As shown, the cutter 211 is provided with a, the rotation speed of the driving wheel 21 is consistent with the transmission speed of the cloth 1, and the driving wheel 21 rotates one circle to form a bending portion 11. At this time, the incision 61 is only located in the folding edge three 113. After cutting by the cutting mechanism 5, the cotton group 7 located on the left side of the central axis P is formed by the cotton pieces 6 with the incision 61 and the cotton pieces 6 without the incision 61 being staggered and stacked, and the cotton group 7 on the right side are all cotton pieces 6 without the incision 61.

[0041] In the sixth embodiment, if Fig.12 As shown, there are three cutters 211, two of which are symmetrically arranged at 180 degrees to each other, and the other cutter 211 is arranged in the middle position between the two symmetrically arranged cutters 211.
