[0002] The slitting and rewinding machine is a device used to unwind the slitting materials, cut them at a fixed width, and then rewind them evenly. It is generally used for professional slitting, multi-layer lamination and rewinding of various films and papers. According to the working process of the slitting and rewinding machine, it can be divided into three parts: unwinding, slitting and rewinding. Among them, the slitting process plays a very important role in the slitting and rewinding machine. The slitting device is one of the important components of the slitting process. The slitting device is mainly used to realize the slitting operation, which can cut wide paper, mica tape or film into multiple narrow materials.

[0003] At present, the slitting device mainly uses slitting circular knives for slitting. However, due to the small gap between the slitting circular knives, it is difficult to further reduce the gap between the slitting circular knives to obtain material slices with narrower widths. In addition, when using slitting circular knives to slitting materials, it is easy to cause the material slices to stick together, thereby reducing the slitting efficiency. Utility Model Content

[0004] In order to at least overcome the above-mentioned deficiencies in the prior art, the purpose of the present application is to provide a slitting device and a slitting and rewinding machine.

[0031] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0032] The specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings.

[0033] Please refer to Figure 1 , Figure 1 A possible structural schematic diagram of the slitting device provided in this embodiment is illustrated. In this embodiment, the slitting device may include a first cutting assembly 100 and a second cutting assembly 200 .

[0034] The first cutting assembly 100 may include a plurality of evenly distributed first cutting blades 110 , and the second cutting assembly 200 may include a plurality of evenly distributed second cutting blades 210 , wherein the first cutting blade 110 is located between two adjacent second cutting blades 210 and contacts one of the second cutting blades 210 .

[0035] The first cutting blade 110 may include a cutting surface, and the second cutting blade 210 may also include a cutting surface. The cutting surface of the first cutting blade 110 and the cutting surface of the second cutting blade 210 cooperate with each other to cut the paper conveyed through the slitting device into multiple paper pieces. The cutting direction of the multiple first cutting blades 110 and the multiple second cutting blades 210 is the same as the conveying direction of the paper.

[0036] In other implementations of this embodiment, the material to be cut by the slitting device is not limited to paper, but may also include non-woven fabrics, mica tapes, films, and composite unidirectional tapes. The type of material to be cut is not specifically limited, as long as the slitting device can cut it.

[0037] Please refer to Figure 2 The plurality of first cutting blades 110 and the plurality of second cutting blades 210 are provided with chamfers.

[0038] In the above structure, by setting chamfers on the first cutting blade 110 and the second cutting blade 210, the gap between the adjacent cutting surfaces of the second cutting blade 210 can be increased, which is more conducive to the cooperation between the first cutting blade 110 and the second cutting blade 210, and can also avoid the material to be cut from sticking to the first cutting blade 110 and the second cutting blade 210, thereby improving the cutting efficiency.

[0039] In addition, since chamfers are provided on the first cutting blade 110 and the second cutting blade 210, the gap between the cutting surfaces of adjacent second cutting blades 210 can be increased. Therefore, the spacing between adjacent second cutting blades 210 of the second cutting assembly 200 can be reduced, and the spacing between the first cutting blades 110 that cooperate with the second cutting blade 210 can be reduced, so that the material to be cut can be cut into finer material slices.

[0040] In a possible implementation, the chamfer angles of the first cutting blade 110 and the second cutting blade 210 are equal.

[0041] In this embodiment, please refer to Figure 2 The angle of the chamfer α of the first cutting blade 110 is equal to the angle of the chamfer β of the second cutting blade 210, and the inclined surface corresponding to the chamfer α of the first cutting blade 110 and the inclined surface corresponding to the chamfer β of the second cutting blade 210 are parallel to each other. In this way, the distance between adjacent second cutting blades 210 of the second cutting assembly 200 can be reduced as much as possible, so that the width of the material slices into which the material to be cut is minimized.

[0042] In a possible implementation, the chamfer angles of the first cutting blade 110 and the second cutting blade 210 may be 45°.

[0043] In a possible implementation, the distance between the plurality of first cutting blades 110 may be 3 mm.

[0044] Specifically, the spacing between the cutting surfaces of two adjacent first cutting blades 110 can be 3 mm, and the spacing between the cutting surfaces of two adjacent second cutting blades 210 can also be 3 mm. In this way, through the cooperation of the first cutting blade 110 and the second cutting blade 210, the material to be cut can be cut into material slices with a width of 3 mm.

[0045] In a possible implementation, the plurality of first cutting blades 110 are of a mesh structure.

[0046] In this embodiment, since the first cutting blade 110 is a mesh structure, the first cutting blade 110 has an elastic space for movement. When the cutting surface of the first cutting blade 110 fits with the cutting surface of the second cutting blade 210, the first cutting blade 110 can be squeezed to make the cutting surface of the first cutting blade 110 fit more closely with the cutting surface of the second cutting blade 210, so that the material slices formed by cutting will not have burrs.

[0047] In one possible implementation, see Figure 3 The slitting device may further include an adjusting component 300 , wherein the adjusting component 300 is connected to the first cutting component 100 , and the adjusting component 300 may be used to adjust the position of the first cutting blade 110 .

[0048] Specifically, the adjustment component 300 can be set on a side of the first cutting component 100. By rotating the adjustment component 300, the first cutting component 100 can be moved in a direction parallel to the first blade axis 130, thereby adjusting the position of the first cutting blade 110 so that the cutting surface of the first cutting blade 110 is in contact with the cutting surface of the second cutting blade 210.

[0049] Exemplarily, the adjusting component 300 may be a rotating wheel, which may be disposed on the first blade shaft 130 of the first cutting component 100 .

[0050] In one possible implementation, please refer again to Figure 1 The first cutting assembly 100 may further include a plurality of tool holders 120 , wherein the plurality of tool holders 120 are in contact with the plurality of first cutting blades 110 respectively, and the plurality of tool holders 120 may be used to realize the positioning of the first cutting blades 110 .

[0051] Specifically, the blade holder 120 may be in the shape of a ring, and each of the first cutting blades 110 is in contact with one of the blade holders 120 . The blade holder 120 may be used to position the first cutting blades 110 .

[0052] In one possible implementation, please refer again to Figure 1 The first cutting assembly 100 may include a first knife shaft 130 , and a plurality of the first cutting blades 110 and a plurality of the knife holders 120 are sleeved on the first knife shaft 130 .

[0053] The second cutting assembly 200 may include a second blade shaft 220 , and a plurality of second cutting blades 210 are sleeved on the second blade shaft 220 .

[0054] In this embodiment, the first blade shaft 130 and the second blade shaft 220 may be cylindrical in shape. A plurality of second cutting blades 210 are fixedly disposed on the second blade shaft 220, and the position of the second cutting blade 210 on the second blade shaft 220 is not adjustable. By adjusting the position of the first cutting assembly 100 through the adjustment assembly 300, the first cutting blade 110 and the second cutting blade 210 can be fitted together.

[0055] In a possible implementation, the plurality of first cutting blades 110 and the plurality of second cutting blades 210 are circular blades, and the chamfers of the first cutting blades 110 and the second cutting blades 210 are arranged at the edges of the circular blades.

[0056] The first cutting assembly 100 may further include a driving assembly, which may be connected to the first blade shaft 130 to drive the first blade shaft 130 to rotate, thereby cutting the material to be cut. Specifically, the driving assembly may be a driving motor. Of course, in some other embodiments, the driving assembly is not limited to the above-mentioned driving motor, and may also be other driving assemblies, which are not specifically limited here.

[0057] The present application example also provides a slitting and rewinding machine, including the slitting device provided in the present embodiment. The slitting device is installed on the frame of the slitting and rewinding machine, and can be combined with other devices to form a slitting and rewinding machine.

[0058] To sum up, this embodiment provides a slitting device and a slitting and rewinding machine. By setting chamfers on the first cutting blade and the second cutting blade, the gap between the cutting surfaces of adjacent second cutting blades can be increased, which is beneficial to the cooperation between the first cutting blade and the second cutting blade. In addition, it can also avoid the adhesion of the material to be cut with the first cutting blade and the second cutting blade, thereby improving the slitting efficiency.

[0059] In addition, since chamfers are provided on the first cutting blade and the second cutting blade, the gap between the cutting surfaces of adjacent second cutting blades can be increased. Therefore, the spacing between adjacent second cutting blades of the second cutting assembly can be reduced, and the spacing between the first cutting blades that cooperate with the second cutting blades can be reduced, so that the material to be cut can be divided into finer material slices.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
