[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0029] In the present application, unless specifically defined and limited otherwise, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0030] In the description of the present embodiment, the terms "up", "down", "left", "right", and other orientation or position relationship are based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0031] Embodiment one provides a self-cleaning cutter roll guide strip for tobacco cutter, which is arranged on the cutter roll to guide the material from the blade, comprising: a connecting strip 1 and a guide strip 2, the connecting strip 1 comprises a mounting part connected with the cutter roll, and a connecting part connected with the guide strip 2; the side of the guide strip 2 away from the connecting strip 1 is a guide surface 21 for guiding the material, the connecting strip 1 is made of rigid material, and the guide strip 2 is made of anti-adhesion material.

[0032] In the self-cleaning cutter roll guide strip, the guide strip 2 is fixed to the cutter roll through the connecting strip 1, and the tobacco material cut by the blade is guided away by the anti-adhesion guide strip 2. Compared with the commonly used guide strip made of alloy steel, the self-cleaning cutter roll guide strip can reduce the adsorption of tobacco dirt and form self-cleaning in the process of normally guiding the tobacco material to leave.

[0033] The guide strip 2 of the present application has a complete guide surface 21 and is entirely made of anti-adhesion material, which has good effect of preventing material adhesion. The connecting strip 1 for connecting the guide strip 2 of the tobacco cutter knife roll is made of rigid material, which is consistent with the original machine and the commonly used guide strip in the prior art, has high reliability, and can solve the problem that the anti-adhesion material is difficult to be reliably connected with the tobacco cutter knife roll.

[0034] In the present embodiment, the tobacco cutter knife roll includes an outward protruding clamping head for mounting the guide strip, and the mounting portion includes a mounting groove 11 penetrating the connecting strip 1 in the length direction and being clamped with the outward protruding clamping head. The existing tobacco cutter knife roll usually has an outward protruding clamping head for mounting the guide strip, for example, the lining strip of the existing guide strip is fixed to the knife roll body by screwing and forms an outward protruding clamping head in the EVO615 original machine; for example, the outward protruding clamping head formed by the outward protruding clamping block and the guide wire block lining strip disclosed in CN202320665975.0. By connecting the guide strip to the outward protruding clamping head through the mounting groove 11, the original machine design can be fully utilized, the present application can be directly adapted to the existing tobacco cutter, and the connection between the present application and the tobacco cutter has the same reliability as the original design.

[0035] Specifically, the mounting groove 11 in the present application is clamped with an outward protruding clamping head formed by a lining strip, and the lining strip is fixed to the tobacco cutter knife roll by screwing.

[0036] In the present embodiment, the connecting strip 1 includes a second mounting groove 13 penetrating in the length direction, and the guide strip 2 includes a third mounting groove 22 corresponding to the second mounting groove 13, and the second mounting groove 13 and the third mounting groove 22 are spliced into a groove for inserting the outward protruding clamping head. The existing tobacco cutter knife roll usually has two outward protruding clamping heads, one of which is located near the blade. For example, the groove spliced by the second mounting groove 13 and the third mounting groove 22 is used for clamping the outward protruding clamping head on the lining strip near the blade. The advantage of such arrangement is that the material that has completed cutting through the blade first contacts the guide strip 2 rather than the connecting strip 1, at this time, the electrostatic of the material is the strongest, the powder-like soot is the most, and the contact with the guide surface is the most sufficient, so that the material at this position first contacts the anti-static material, which can greatly improve the effect of preventing soot adsorption of the self-cleaning tobacco cutter knife roll guide strip.

[0037] In the present embodiment, the connecting strip 1 and the guide strip 2 have equal lengths, and the connecting portion includes a guide strip connecting groove 12 penetrating the connecting strip 1 in the length direction, the guide strip connecting groove 12 includes a limiting surface 14 limiting the guide strip 2 in the direction perpendicular to the length direction, and the guide strip 2 has a shape corresponding to the guide strip connecting groove 12 and is clamped with the connecting strip 1. The connecting strip 1 and the guide strip 2 are both long strips, and the clamping groove in the length direction stably and reliably clamps the connecting strip 1 and the guide strip 2. Considering the shape of the guide surface 21, the cross section of the connecting strip 1 and the guide strip 2 perpendicular to the length direction is approximately "L" shape, which is easy to set and clamp.

[0038] In the embodiment, the two side faces of the guide strip 2 are chamfered away from the guide face 21, and the guide strip connecting groove 12 also has a shape corresponding to the chamfer to reduce stress concentration and creep, fracture or fragmentation when the application is stressed. In particular, the guide strip 2 is made of ceramic material in the embodiment, and the chamfer is used to avoid fracture at the "L" shaped transition without the chamfer or round corner.

[0039] In the embodiment, the limiting face 14 is a plane with an angle of 45° with the bottom face of the guide strip connecting groove 12 to limit the clamping of the connecting strip 1 and the guide strip 2 and reduce the reaction force on the limiting face 14 when the tobacco material moves along the guide face 21. The limiting face 14 can have an angle of 45°-75° with the bottom face of the guide strip connecting groove 12 to achieve similar effects, and the angle within the range has a certain thickness.

[0040] In the embodiment, the top face of the guide strip connecting groove 12 is smoothly connected with the guide face 21 to reduce the gap and avoid dirt accumulation.

[0041] In the embodiment, the guide face 21 is a curved surface corresponding to a circular arc in the vertical length direction to uniformly and smoothly guide the tobacco in all directions.

[0042] In the embodiment, the guide strip 2 is made of ceramic material, which has low cost and good anti-absorption property. In other embodiments, the guide strip 2 can also be made of high polymer material, such as polytetrafluoroethylene.

[0043] Embodiment two provides a self-cleaning cutter roll guide strip of a tobacco cutter basically the same as that of embodiment one, and the difference is that the limiting face 14 in embodiment two is a curved surface corresponding to a circular arc in the vertical length direction, which has an average contact with the bottom face of the guide strip connecting groove 12 in all directions, but the processing difficulty of the guide strip connecting groove 12 is slightly larger.

[0044] The above description can be implemented alone or in various combinations, and these variants are within the protection scope of the utility model.

[0045] It is to be noted that the relational terms herein, such as first and second, and the like, are used solely to distinguish one from another entity or action without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0046] The above further describes the present application in detail in connection with specific preferred embodiments. It is to be understood that the specific embodiments described above are not to be construed as limiting the present application, but merely as illustrative of the present application. Those skilled in the art to which the present application pertains will be able to make numerous simple substitutions or modifications of the present application without departing from the scope of the present application.
