Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging, and particularly relates to a cutter cover for cigarette inner lining paper. Background Art

[0002] The inner lining paper is the inner packaging paper for cigarette small boxes and is made of aluminum foil paper. Refer to Figure 1 , the power of the inner lining paper cutting knife shaft 300 of the small box packaging machine comes from the main drive system of the right body of the main machine. The rotation speed of the inner lining paper cutting knife shaft 300 is 1 / 2 of the rotation speed of the fixed inner lining paper cutting knife shaft 600. That is, the fixed cutting knife 500 contacts the adjustable long cutting knife 400 and the adjustable short cutting knife 200 once every two rotations respectively, completing the fixed-length cutting of the inner lining paper and the longitudinal dotted line cutting of the inner lining paper pull tab. Knife covers 100 are installed at positions on the inner lining paper cutting knife shaft 300 where the adjustable long cutting knife 400 and the adjustable short cutting knife 200 are attached.

[0003] Currently, during the conveying and cutting process of the inner lining paper, there is a poor cutting phenomenon of "gnawing marks", which affects the packaging folding and forming effect of the inner lining paper and the packaging quality of subsequent processes, resulting in packaging forming problems such as the inner lining paper being scratched and having poor folding corners.

[0004] In view of the above problems, the creator of the utility model finally obtained the present utility model through long-term research and practice. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a cutter cover for cigarette inner lining paper, which can eliminate the poor cutting phenomenon of "gnawing marks" during the conveying and cutting process of the inner lining paper, and improve the packaging folding and forming effect of the inner lining paper and the packaging quality of subsequent processes.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A cutter cover for cigarette inner lining paper is provided. The whole is in a semi-cylindrical shape and is fixed on the inner lining paper cutting knife shaft of the small box packaging machine; inclined eaves are respectively provided on the upper edge and the lower edge in the axial direction of the cutter cover. The inclined surface of the eaves on the upper edge in the axial direction fits with the cutting edge surface of the adjustable short cutting knife, and the inclined surface of the eaves on the lower edge in the axial direction fits with the cutting edge surface of the adjustable long cutting knife.

[0008] Furthermore, the whole cutter cover is made of aluminum alloy material.

[0009] Furthermore, two arc grooves are spaced on the inner arc surface of the cutter cover for accommodating the adjusting set screws of the adjustable short cutting knife and the adjustable long cutting knife.

[0010] Furthermore, the two arc grooves divide the inner arc surface of the cutter cover into two spaced arc surfaces that fit with the inner lining paper cutting knife shaft, namely the first arc surface and the second arc surface, and the first arc surface is located between the two arc grooves.

[0011] Further, two first fixing holes arranged circumferentially are provided on the first arc surface, and two second fixing holes arranged axially are provided on the second arc surface. Bolts pass through the first fixing holes and the second fixing holes to be connected with the inner liner paper cutter shaft.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model provides a novel cigarette inner liner paper cutter cover, which has a simple structure and is convenient to install. By closely fitting the cutter cover with the cutter blade, it is possible to avoid the "biting mark" cutting defect generated during the conveying and cutting of the inner liner paper due to the break groove between the cutter blade and the cutter cover, which affects the packaging folding and forming effect of the inner liner paper and the packaging quality of the subsequent processes, and causes problems such as the inner liner paper being scratched and the corner folding being defective in the packaging forming.

[0020] The following will further elaborate on the above-mentioned and other technical features and advantages of the present utility model in more detail in conjunction with the drawings.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0022] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, "a plurality of" means at least two, unless otherwise specifically defined.

[0023] Currently, during the process of feeding and cutting the inner lining paper, there is a poor cutting phenomenon of "gnawing marks" generated during the feeding and cutting process of the inner lining paper. After long-term research by the creator of the present utility model, it is found that: Refer to Figure 1 , it is because the cutter cover 100 in the existing equipment cannot be closely attached to the blade of the inner lining paper, resulting in a broken groove, especially a broken groove between the cutter cover 100 of the inner lining paper and the adjustable short cutter 200 of the inner lining paper, causing poor cutting of "gnawing marks" during the feeding and cutting process of the inner lining paper, and further resulting in packaging forming problems such as the inner lining paper being scratched and having poor folding angles.

[0024] As Figures 2 - 5 shown, the present utility model provides a cutter cover for cigarette inner lining paper, which is integrally semi-cylindrical and fixed on the inner lining paper cutter shaft 300 of the small box packaging machine. Tilted eaves 5 and 6 are respectively provided on the upper edge and the lower edge in the axial direction of the cutter cover of the inner lining paper. The inclined surface of the eaves 5 on the upper edge in the axial direction is attached to the blade surface of the adjustable short cutter 200, and the inclined surface of the eaves 6 on the lower edge in the axial direction is attached to the blade surface of the adjustable long cutter 400. This avoids the occurrence of a broken groove between the cutter cover and the blade, thereby eliminating the generation of "gnawing marks". Preferably, the whole cutter cover is made of aluminum alloy material.

[0025] In some preferred embodiments, two arc grooves 7 are spaced on the inner arc surface of the cutter housing for accommodating the adjusting set screws of the adjustable short cutter and the adjustable long cutter. The adjusting set screws are used to adjust the length of the cutter. The arc grooves 7 avoid interference with the adjusting set screws, so that the convex eaves 5 and 6 can be closely attached to the cutting edge surface. The two arc grooves 7 divide the inner arc surface of the cutter housing into two spaced arc surfaces that fit the inner liner paper cutter shaft 300, namely the first arc surface 1 and the second arc surface 2. The first arc surface 1 is located between the two arc grooves 7. The first arc surface 1 and the second arc surface 2 hold the outer circumference of the inner liner paper cutter shaft 300 to ensure the positional relationship between the convex eaves 5 and 6 and the cutting edge surface.

[0026] Two first fixing holes 3 arranged circumferentially are provided on the first arc surface 1, and two second fixing holes 4 arranged axially are provided on the second arc surface. Bolts pass through the first fixing holes 3 and the second fixing holes 4 to be connected with the inner liner paper cutter shaft 300. The two circumferentially arranged first fixing holes 3 ensure that the cutter housing can be stressed circumferentially, and the two axially arranged second fixing holes 4 ensure that the cutter housing can be stressed axially, ensuring the position of the cutter housing during operation, and thus avoiding the occurrence of broken grooves between the cutter housing and the cutting edge during long-term operation. Thereby, the generation of "gnawing marks" during the cutting process is completely eliminated, improving the packaging folding and forming effect of the inner liner paper and the packaging quality of subsequent processes.

[0027] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. The structures and connection methods of the various components in the present invention can all be changed. Any equivalent transformation and improvement based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
