[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figures 1 to 4 The utility model provides a folding roller group mechanism for a high-speed folding machine, comprising a first folding roller 1 and a second folding roller 2.

[0032] The first folding roller 1 and the second folding roller 2 are arranged horizontally and a conveying channel 11 for conveying the to-be-folded paper from top to bottom is formed therebetween, and the second folding roller 2 points to the first folding roller 1 in a first direction; a plurality of first adsorption grooves 12 are arranged at intervals along the circumference of the first folding roller 1 on the outer side thereof, and the first adsorption grooves 12 are used to adsorb the to-be-folded paper protruding in the first direction to form a first crease; a plurality of first knife-leaving grooves 13 are also arranged at intervals along the circumference of the first folding roller 1 on the outer side thereof; a plurality of second adsorption grooves 21 are arranged at intervals along the circumference of the second folding roller 2 on the outer side thereof, and the second adsorption grooves 21 are used to adsorb the to-be-folded paper protruding in the first direction to form a first crease The second folding roller 2 is provided with a plurality of first cutters 22 at intervals along its circumference on the outside of the second folding roller 2, and the first cutter 22 is used to cooperate with the second cutter provided outside the second folding roller 2 to cut the paper to be folded; the first cutter-allowing groove 13 is used for the first cutter 22 to let the cutter go at the conveying channel 11; the first folding roller 1 is provided with a plurality of first folding knives 14 at intervals along its circumference on the outside of the first folding roller 1 for one-to-one cooperation with the second adsorption groove 21; the second folding roller 2 is provided with a plurality of second folding knives 23 at intervals along its circumference on the outside of the second folding roller 2 for one-to-one cooperation with the first adsorption groove 12.

[0033] When the first folding roller 1 and the second folding roller 2 convey the paper to be folded, the second folding knife 23 is used to press the paper to be folded toward the first adsorption groove 12 at the conveying channel 11 to form a first crease, and the first folding knife 14 is used to press the paper to be folded toward the second adsorption groove 21 at the conveying channel 11 to form a second crease.

[0034] The folding roller group mechanism for a high-speed folding machine provided by the utility model is provided with components such as the first folding roller 1 and the second folding roller 2. In actual application, the first cutter 22 and the second cutter are used to cut the paper to be folded, and the paper to be folded is cut into sheets of paper connected in sequence. Then, for each sheet of paper, the first folding mark is formed by the adsorption effect of the first adsorption groove 12 and the squeezing effect of the second paper folding knife 23, and then the second folding mark is formed by the adsorption effect of the second adsorption groove 21 and the squeezing effect of the first paper folding knife 14. Then, the paper to be folded can be pressed together with the pressing device. By providing the above structure, when the conveying speed of the paper to be folded is increased, the adsorption effect of the adsorption groove and the squeezing effect of the paper folding knife can form folds on the paper to be folded, which is beneficial to the production of paper.

[0035] Among them, the maximum conveying speed of the paper to be folded provided by the existing folding roller group structure is generally 50m / min. When the conveying speed of the paper to be folded is higher than 50m / min, it is not easy for the paper to be folded to form creases, which is not conducive to the production of paper. However, by setting the above-mentioned structure, the utility model can form creases on the paper to be folded when the conveying speed of the paper to be folded is higher than 50m / min, specifically 80-100m / min, through the adsorption effect of the adsorption groove and the extrusion effect of the folding knife, which is conducive to the production of paper.

[0036] In order to better reflect the technical points of the present invention, the number and position of the first adsorption groove 12 and the second adsorption groove 21 will be further described in detail below. Through different embodiments, various folding forms of the folded paper can be achieved, which can meet the needs of multi-functional equipment in actual production.

[0037] According to the above-mentioned cutting and folding steps, it can be known that the first crease and the second crease formed in sequence for the first time are located on the same piece of paper after cutting, and the first crease and the second crease formed in sequence for the second time are located on the same piece of paper after cutting. Similarly, the first crease and the second crease formed in sequence for the Nth time are located on the same piece of paper after cutting; therefore, the cutting line after cutting by the cutting assembly is located between the first crease of the previous piece of paper and the second crease of the next piece of paper.

[0038] In particular, since the first crease and the second crease formed sequentially for the first time are located on the same piece of paper after cutting, for the convenience of description, the first piece of paper is used as a reference for explanation here. As a preferred technical solution, by setting the relative positions of the first adsorption groove 12, the second adsorption groove 21, the first origami knife 14 and the second origami knife 23, the first crease and the second crease are formed in sequence at the two quarters of the first piece of paper through the cooperation of the first adsorption groove 12, the second adsorption groove 21, the first origami knife 14 and the second origami knife 23, and the first crease and the second crease corresponding to the to-be-folded paper are alternately compressed one by one through the laminating device. Specifically, the technical solutions to achieve the above technical requirements are mainly as follows:

[0039] In preferred embodiment 1, the first adsorption groove 12, the second adsorption groove 21 and the first cutter 22 are each provided with one, and the circumferential angle of the second folding roller 2 corresponding to the second adsorption groove 21 and the first cutter 22 is 90° or 270°; the specific implementation steps are as follows:

[0040] When the first folding roller 1 and the second folding roller 2 cooperate to rotate one circle to convey only one piece of paper, for the convenience of description, the rotation angle of the first folding roller 1 will be used as a reference system. When the first folding roller 1 is not rotating, one end of the piece of paper is in the conveying channel 11. When the first folding roller 1 rotates 90°, the first adsorption groove 12 and the second folding knife 23 are used to form the first fold mark, and then the paper to be folded with the first fold mark is compressed downward by a laminating device. When the first folding roller 1 rotates 270°, the second adsorption groove 21 and the first folding knife 14 are used to form the second fold mark, and then the paper to be folded with the second fold mark is compressed downward by laminating. When the first folding roller 1 rotates 360°, it can also be regarded as returning to the starting point. The above steps can be repeated to continuously fold the paper to be folded.

[0041] In the preferred embodiment 2, two of each of the first adsorption groove 12, the second adsorption groove 21 and the first cutter 22 are provided, and the two second adsorption grooves 21 and the two first cutters 22 are alternately distributed along the circumference of the second folding roller 2. The circumferential angle of the second folding roller 2 corresponding to the adjacent second adsorption grooves 21 and the first cutter 22 is 45° or 135°; the specific implementation steps are as follows:

[0042] When the first folding roller 1 and the second folding roller 2 cooperate to rotate one circle and only convey two pieces of paper, for the convenience of description, the rotation angle of the first folding roller 1 will be used as a reference system. When the first folding roller 1 is not rotating, one end of the piece of paper is in the conveying channel 11. When the first folding roller 1 rotates 45°, the first adsorption groove 12 and the second folding knife 23 are used to form the first fold mark, and then the paper to be folded with the first fold mark is compressed downward by a laminating device. When the first folding roller 1 rotates 135°, the second adsorption groove 21 and the first folding knife 14 are used to form the second fold mark, and then the paper to be folded with the second fold mark is compressed downward by a laminating device. When the first folding roller 1 rotates 180°, it can also be regarded as returning to the starting point. The above steps can be repeated to continuously fold the paper to be folded.

[0043] In preferred embodiment 3, three first adsorption grooves 12, three second adsorption grooves 21 and three first cutters 22 are respectively provided, and the three second adsorption grooves 21 and the three first cutters 22 are alternately distributed along the circumference of the second folding roller 2. The circumferential angle of the second folding roller 2 corresponding to the adjacent second adsorption grooves 21 and the first cutters 22 is 30° or 90°; the specific implementation steps are as follows:

[0044] When the first folding roller 1 and the second folding roller 2 cooperate to rotate one circle and only convey three pieces of paper, for the convenience of description, the rotation angle of the first folding roller 1 will be used as a reference system. When the first folding roller 1 is not rotating, one end of the piece of paper is in the conveying channel 11. When the first folding roller 1 rotates 30°, the first adsorption groove 12 and the second folding knife 23 are used to form the first fold mark, and then the paper to be folded with the first fold mark is compressed downward by a laminating device. When the first folding roller 1 rotates 90°, the second adsorption groove 21 and the first folding knife 14 are used to form the second fold mark, and then the paper to be folded with the second fold mark is compressed downward by a laminating device. When the first folding roller 1 rotates 120°, it can also be regarded as returning to the starting point. The above steps can be repeated to continuously fold the paper to be folded.

[0045] Special note: The above preferred embodiment 3 is the best embodiment of the utility model. However, according to the enumeration of the above preferred solutions, the angle positions corresponding to the structures such as the first adsorption groove 12 and the second adsorption groove 21 can be adjusted automatically, that is, the positions of the first adsorption groove 12 and the second adsorption groove 21 include but are not limited to the three preferred solutions listed above. Therefore, if only the technical solution of making some simple angle changes to the relevant technical features of the utility model is made, it will also fall within the protection scope of the utility model. In addition, in the above three preferred solutions, the first fold and the second fold are formed in sequence at the two quarters of the first sheet of paper through the first adsorption groove 12 and the second adsorption groove 21 respectively. However, in the actual production process, it may also be necessary to form the first fold and the second fold at the two fifths, two sixths, one fifth and one sixth or other similar positions of the first sheet of paper through the first adsorption groove 12 and the second adsorption groove 21 respectively. Therefore, if only the technical solution of making some simple angle changes to the folding position of the to-be-folded paper produced by the utility model is made, it will also fall within the protection scope of the utility model. Therefore, the utility model can realize various folding forms of the to-be-folded paper by adjusting the number and position of the first adsorption grooves 12 and the second adsorption grooves 21, and can meet the demand for multifunctional equipment in actual production.

[0046] Among them, the two quarters of the first piece of paper mentioned above refer to one quarter of the first piece of paper relative to one end in the conveying direction, and one quarter of the first piece of paper relative to the other end in the conveying direction. Similarly, one-fifth or one-sixth of the first piece of paper can be interpreted as one quarter of the first piece of paper, and no further explanation is given here.

[0047] The paper to be folded can be non-woven fabric, paper towel material, etc. The folding roller group mechanism used in the high-speed folding machine of the utility model is mainly used to make products such as wet toilet paper and non-woven wet wipes.

[0048] Among them, the formation order of the first crease and the second crease can be changed, which will not affect the working principle of the technical solution of the utility model, and therefore, shall not be understood as a limitation of the utility model.

[0049] In order to realize the multifunctional application of the folding processing equipment, a plurality of third cutters 15 are arranged at intervals along the circumference of the first folding roller 1 on the outside thereof, and the third cutters 15 are used to cooperate with the fourth cutter arranged outside the first folding roller 1 to cut the paper to be folded; a plurality of second cutter-release grooves 24 are also arranged at intervals along the circumference of the second folding roller 2 on the outside thereof, and the second cutter-release grooves 24 are used for the third cutter 15 to release the cutter at the conveying passage 11. By arranging the first cutter 22, the second cutter, the third cutter 15 and the fourth cutter, the first folding roller 1 and the second folding roller 2 can both be used as main rollers (that is, the paper to be folded can be input from the first folding roller 1 or the second folding roller 2). Such a design increases the conveying function of the folding processing equipment and increases the conveying position of the paper to be folded. When the folding equipment is not convenient to move or the paper conveying position is blocked, a folding roller that is convenient for paper feeding can be selected as the main roller, so that it can better adapt to the actual application scenario.

[0050] Working principle: The first cutter 22 and the second cutter are used to cut the paper to be folded into sheets of paper connected in sequence. Then, each piece of paper is first subjected to the adsorption effect of the first adsorption groove 12 and the extrusion effect of the second folding knife 23 to form the first crease. Then, the second adsorption groove 21 and the extrusion effect of the first folding knife 14 are used to form the second crease. Then, the paper to be folded can be pressed together with the pressing equipment.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
