[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] Reference Figures 1 to 3 As shown, this embodiment provides a tobacco strip cutter, which includes a support body 100 and a cutting blade 200. The support body 100 has adjacent mounting end faces 110 and guide arc surfaces 120; the cutting blade 200 is fitted to the mounting end face 110, and the bottom edge of the cutting blade 200 protrudes from the mounting end face 110. The bottom edge of the cutting blade 200 is used to cut the tobacco strip compressed by the guide arc surface 120, and the guide arc surface 120 can guide the cut tobacco strip to the target position.

[0041] Understandably, during the cutting of the tobacco stick, the support body 100 moves towards the tobacco stick and compresses it through the guide arc surface 120. Under the pressure of the guide arc surface 120, the bottom edge of the slicer 200 cuts the tobacco stick. The compression by the guide arc surface 120 makes the tobacco shreds within the tobacco stick more compact, reducing the probability of failed cutting. Furthermore, the guide arc surface 120 guides the cut tobacco stick to a target location, such as a waste bin, for centralized collection and convenient disposal.

[0042] Understandably, a thinner slice 200 concentrates the pressure applied to the cigarette strip during cutting, which helps reduce the probability of failure in making the cigarette strip. For example, the thickness of the slice 200 can be 0.3mm-0.8mm, such as 0.5mm, which helps to make the cut surface of the cigarette strip flush.

[0043] For example, the shape of slice 200 can be set to rectangle.

[0044] For example, the material of the slicing blade 200 is stainless steel, such as 304 stainless steel, which helps reduce wear on the slicing blade 200. The slicing blade 200 has a hardness ≥217HB and high-temperature resistance meeting the requirements of 180℃-220℃ operating conditions. Its surface used for cutting cigarette sticks is mirror-finished to reduce frictional resistance, which helps reduce the probability of cigarette stick cutting failure. For example, the surface roughness of the slicing blade 200 used for cutting cigarette sticks is ≤Ra1.6. For example, the slicing blade 200 can be formed by laser cutting.

[0045] For example, the support body 100 can be made of plastic, such as nylon, to facilitate molding and manufacturing. In some embodiments, the support body 100 can be manufactured by 3D printing.

[0046] In some embodiments, a positioning groove (not shown) is provided on the mounting end face 110, and the slice 200 is installed in the positioning groove for convenient positioning and assembly. It is understood that the shape of the positioning groove is the same as that of the slice 200.

[0047] For example, the depth of the positioning groove along the first direction is 1mm-2mm, such as 1.5mm. The first direction can be set as the thickness direction of the slice 200.

[0048] In some embodiments, continue to refer to Figures 1 to 3 As shown, the support body 100 also includes a tail end face 130 disposed opposite to the mounting end face 110 along a first direction. A guide groove 121 is provided on the guide arc surface 120, and the guide groove 121 penetrates the tail end face 130. The groove wall of the guide groove 121 is used to guide the cut tobacco stick to the target position. It can be understood that the setting of the guide groove 121 is more conducive to guiding the cut tobacco stick to fall to the target position; and the groove wall of the guide groove 121 squeezes the tobacco stick, which can reduce the degree of bending of the tobacco stick while guiding the cut tobacco stick, and helps to ensure that the retained tobacco stick maintains good straightness.

[0049] In one feasible implementation, the dimension B1 of the guide groove 121 near the support body 100 along the second direction is smaller than the dimension B2 of the guide groove 121 away from the support body 100 along the second direction. This reduces the constraint on the tobacco strip when the groove wall of the guide groove 121 compresses it, which is beneficial for achieving a good compression effect on the tobacco strip. The first and second directions are perpendicular to each other. The second direction can be set as the length direction of the slice 200.

[0050] In one feasible implementation, a clearance groove 122 is provided on the guide arc surface 120. The clearance groove 122 and the guide groove 121 are arranged opposite to each other along the first direction. The clearance groove 122 can allow the tobacco strip to be moved, which is beneficial for the tobacco strip cutter to cut the tobacco strip.

[0051] For example, the relief groove 122 and the guide groove 121 intersect at their ends facing each other.

[0052] For example, at least one guide groove 121 is provided, such as two along the second direction, and the clearance groove 122 is provided in a one-to-one correspondence with the guide groove 121. The number of guide grooves 121 can be the number of tobacco strips that the slice 200 cuts at the same time.

[0053] In another feasible implementation, the guide groove 121 extends through the mounting end face 110, that is, the guide arc surface 120 does not have a relief groove 122. In other words, the relief groove 122 is part of the guide groove 121.

[0054] In some embodiments, refer to Figures 1 to 4 As shown, the support body 100 and the slice 200 are detachably connected so that the slice 200 can be replaced individually after wear, reducing maintenance costs.

[0055] In one feasible implementation, the strip applicator further includes two screw-in components 300. The strip 200 is provided with two positioning holes 210 spaced apart along the second direction. The screw-in components 300 are provided in a one-to-one correspondence with the positioning holes 210. The screw-in components 300 pass through the corresponding positioning holes 210 and are threadedly connected to the support body 100. The connection is stable and reliable, and easy to disassemble and assemble.

[0056] For example, the screw connector 300 can be a screw, such as an internal hexagonal flat head screw.

[0057] For example, the support body 100 is embedded with a threaded sleeve (not shown), and the screw connector 300 is threadedly connected to the threaded sleeve to improve the connection stability between the support body 100 and the slice 200.

[0058] For example, the positioning hole 210 is configured as an oblong hole, and the length direction of the oblong hole extends along a third direction, so that the distance by which the bottom edge of the slice 200 protrudes from the mounting end face 110 is adjustable, ensuring that the bottom edge of the slice 200 is suitable for cutting tobacco strips. The second direction and the third direction are perpendicular to each other. The third direction can be defined as the width direction of the slice 200 and the direction in which the slice 200 cuts the tobacco strip, i.e., the first direction, the second direction, and the third direction are perpendicular to each other. It is understood that the distance by which the bottom edge of the slice 200 protrudes from the mounting end face 110 refers to the distance by which the bottom edge of the slice 200 protrudes from the mounting end face 110 along the third direction.

[0059] For example, the bottom edge of the slice 200 protrudes from the mounting end face 110 by a distance H1 of 0.45mm-0.55mm, such as 0.5mm, which is beneficial for cutting the tobacco strip and improves the structural stability of the slice 200.

[0060] For example, the allowable adjustment of the distance by which the bottom edge of the slice 200 protrudes from the mounting end face 110 is ±0.1 mm.

[0061] In some embodiments, refer to Figure 2 and Figure 3 As shown, the support body 100 has a connecting ear 140 on one side along the second direction, and the connecting ear 140 has a fixing hole 141. The connection between the drive component for driving the support body 100 to cut the cigarette bar and the support body 100 can be that a screw passes through the fixing hole 141 and is fastened to the drive end of the drive component.

[0062] For example, the connecting ear 140 is provided with at least two fixing holes 141.

[0063] Reference Figures 1 to 5 As shown, this embodiment also provides a cigarette rolling machine, which includes a support (not shown), a conveying structure, a driving component (not shown), and the aforementioned tobacco strip cutter. Both the conveying structure and the driving component are mounted on the support. The conveying structure includes a discharge end drive roller 400, a feed end drive roller (not shown), and a conveyor belt 500 wound around the discharge end drive roller 400 and the feed end drive roller. The conveyor belt 500 is used to convey tobacco strips. The driving component is connected to the support body 100 and is used to drive the slicer 200 to cut the tobacco strips at the discharge end drive roller 400. In this embodiment, by setting the aforementioned tobacco strip cutter, the cigarette rolling machine helps to reduce the probability of tobacco strip cutting failure and achieves centralized collection of cut tobacco strips.

[0064] For example, the minimum distance H2 between the slice 200 and the discharge end drive roller 400 ranges from 1.5mm to 2mm. It can be understood that when the distance between the slice 200 and the discharge end drive roller 400 is at its minimum, the slice 200 can cut the tobacco strip.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
