Description

Technical Field

[0001] This utility model relates to the technical field of cigarette box manufacturing equipment, and in particular to a cigarette pack inner frame paper rolling cutter and a cigarette pack inner frame paper rolling cutter. Background Technology

[0002] A tobacco packaging box is a box used to hold cigarettes, consisting of an inner frame paper, a label paper, a transparent paper, and a gold pull tab. The inner frame paper is glued to the label paper with latex. It primarily serves to position the lid of the hard-pack cigarette pack after it is formed, and also supports the aluminum foil packaging, maintaining the orderly arrangement of the cigarettes inside and ensuring the pack has a square appearance.

[0003] Typically, the inner frame paper of a cigarette box is made by cutting paper strips. In the prior art, the cutting device for the inner frame paper of a cigarette box includes an integral cutting roller with a cutting blade on it. When the cutting roller rotates, the cutting blade cuts the continuous paper strip into individual inner frame papers.

[0004] However, there are two key technical defects in the existing technology: First, the outer surface of the inner frame paper is coated with a layer of aluminum powder or oil film. This coating not only makes it difficult for the glue applied to the inner frame paper to remain, resulting in a reduction in the amount of glue applied, but also makes it difficult for the glue to penetrate into the fiber layer of the inner frame paper or the underlying material that is easier to bond. This leads to poor adhesion between the inner frame paper and the label paper, and quality defects such as the inner frame paper falling off are prone to occur. Second, the cutter roller is an integral structure. After the cutter wears out, the entire cutter roller must be replaced, which increases the cost of use. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting tool for the inner frame paper of cigarette packs, which can not only reduce maintenance costs but also prevent poor adhesion between the inner frame paper and the label paper.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The inner frame paper cutting knife for cigarette packs includes:

[0008] The cutter roller can be connected to a drive mechanism, which can drive the cutter roller to rotate.

[0009] The blade plate is detachably mounted on the outer circumferential surface of the cutter roller;

[0010] A cutting blade is disposed on the surface of the blade plate away from the blade roller, and is used to cut the inner frame paper of the cigarette pack;

[0011] A pressure block is disposed on the surface of the blade away from the blade roller. The surface of the pressure block away from the blade roller can press against the inner frame paper of the cigarette pack, and is used to imprint a groove on the surface of the inner frame paper of the cigarette pack that can accommodate latex and damage the coating on the surface of the inner frame paper of the cigarette pack.

[0012] Preferably, the surface of the pressure block away from the cutter roller is provided with protrusions for pressing the coating.

[0013] Preferably, the pressure block is detachably connected to the blade.

[0014] Preferably, the surface of the blade away from the blade roller is provided with a mounting hole, and the surface of the pressure block near the blade is provided with a mounting post, the mounting post being able to be inserted into the mounting hole and detachably connected to the mounting hole.

[0015] Preferably, a plurality of blades are arranged along the circumference of the blade roller, and each blade is provided with a cutting blade and at least one pressing block.

[0016] Preferably, the inner frame paper cutting knife of the cigarette pack further includes:

[0017] A connector is provided, wherein the blade plate is provided with a connecting hole, and the connector can pass through the connecting hole and be detachably connected to the blade roller to detachably fix the blade plate to the blade roller.

[0018] Preferably, the outer peripheral surface of the cutter roller is provided with a first mounting groove, the cutter plate (2) is accommodated in the first mounting groove, and the groove wall of the first mounting groove abuts against the side wall of the cutter plate.

[0019] Preferably, the cutter roller comprises:

[0020] The body is used to mount the blade plate. Both ends of the body along the axis are provided with drive shafts, which can be connected to the drive mechanism.

[0021] As a preferred option, the inner frame paper cutting knife for cigarette packs also includes:

[0022] The dotted line cutter is located on the surface of the cutter plate away from the cutter roller and is used to cut dotted lines in the inner frame paper of the cigarette pack.

[0023] This utility model also provides a cigarette pack inner frame paper rolling cutter, comprising:

[0024] Such as the cigarette pack inner frame paper cutting knife of this utility model;

[0025] A drive mechanism is used to drive the cutter roller to rotate.

[0026] The beneficial effects of this utility model are:

[0027] The cigarette pack inner frame paper cutting knife provided by this utility model includes a knife roller connected to a drive mechanism, a knife plate detachably mounted on the outer circumferential surface of the knife roller, a cutting knife disposed on the surface of the knife plate away from the knife roller, and a pressure block disposed on the surface of the knife plate away from the knife roller. On the one hand, since the cutting knife is detachably mounted on the outer circumferential surface of the knife roller through the knife plate, the worn cutting knife can be replaced by replacing the knife plate after the cutting knife is worn. On the other hand, when the pressure block presses against the cigarette pack inner frame paper, the surface of the pressure block away from the knife roller can imprint a groove on the surface of the cigarette pack inner frame paper and destroy the coating on the surface of the cigarette pack inner frame paper. The latex contained in the groove tends to remain stably inside the groove due to the geometric enclosure effect of the groove and the influence of the latex's own surface tension, thus increasing the amount of adhesive. At the same time, since the coating on the inner wall of the groove is destroyed, the latex can directly contact the fiber layer of the inner frame paper or the underlying material that is easier to bond, thereby enhancing the adhesion between the latex and the paper, improving the bonding effect of the inner frame paper, and reducing the possibility of the inner frame paper falling off.

[0032] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] 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 or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or 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 according to the specific circumstances.

[0034] In the description of this utility model, unless otherwise expressly 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.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 3 As shown, this utility model provides a cigarette pack inner frame paper roller cutter, including a cutter roller 1 that can be connected to a drive mechanism, a cutter plate 2 that is detachably mounted on the outer periphery of the cutter roller 1, a cutting blade 3 disposed on the surface of the cutter plate 2 away from the cutter roller 1, and a pressure block 4 disposed on the surface of the cutter plate 2 away from the cutter roller 1.

[0037] On the one hand, since the cutting blade 3 is detachably mounted on the outer circumference of the blade roller 1 via the blade plate 2, the worn cutting blade 3 can be replaced by replacing the blade plate 2 after wear occurs. On the other hand, when the pressure block 4 presses against the inner frame paper of the cigarette pack, the surface of the pressure block 4 away from the blade roller 1 can imprint a groove on the surface of the inner frame paper of the cigarette pack. The coating on the inner wall of the groove is destroyed under the stretching, squeezing and / or cutting action of the pressure block 4 away from the surface of the blade roller 1. The latex contained in the groove tends to remain stably inside the groove due to the geometric enclosure effect of the groove and the surface tension of the latex itself, which increases the amount of adhesive. At the same time, since the coating on the inner wall of the groove is destroyed, the latex can directly contact and penetrate into the inner frame paper's fiber layer or a more easily bonded bottom material, thereby enhancing the adhesion between the latex and the paper, thus improving the bonding effect of the inner frame paper and reducing the possibility of the inner frame paper falling off.

[0038] Optionally, the pressing block 4 can be a cube with its top surface facing the inner frame paper. In this case, the top surface of the cube can imprint a groove on the surface of the inner frame paper of the cigarette pack, and the edge of the top surface has a cutting effect to damage the coating on the surface of the inner frame paper of the cigarette pack. The pressing block 4 can also be a cube with its sides facing the inner frame paper. The sides of the pressing block 4 can imprint a groove on the surface of the inner frame paper of the cigarette pack. The edge line on the side of the pressing block 4 has a cutting effect, and the inner wall of the groove is stretched by the side of the pressing block 4 to damage the coating on the surface of the inner frame paper of the cigarette pack. The pressing block 4 can also be a sphere, whose surface can not only imprint a groove on the surface of the inner frame paper of the cigarette pack, but also stretch the inner wall of the groove to damage the coating on the surface of the inner frame paper of the cigarette pack.

[0039] Optionally, the pressing block 4 can be composed of multiple parallel and spaced cuboids, or multiple grooves extending through the pressing block 4 along the length direction can be arranged in parallel on the surface of the pressing block 4 away from the cutter roller 1 to form multiple parallel protrusions. In this case, the surface of each protrusion away from the cutter roller 1 presses against the inner frame paper of the cigarette pack to imprint a groove on the surface of the inner frame paper of the cigarette pack. Although the total cross-sectional area of ​​all the grooves on the surface of the inner frame paper of the cigarette pack is reduced, resulting in a reduction in the amount of latex that can be accommodated in the grooves, the number of edges that can achieve a cutting effect to damage the surface of the inner frame paper of the cigarette pack is increased, thus increasing the degree of damage to the coating.

[0040] For example, the maximum distance between the surface of the pressure block 4 away from the knife roller 1 and the surface of the knife plate 2 away from the knife roller 1 is less than the thickness of the inner frame paper strip, thereby preventing the pressure block 4 from crushing the inner frame paper strip.

[0041] Optionally, the edge of the pressure block 4 away from the cutter roller 1 can be a zigzag, a curve, and / or a wavy line. For example, the cross-section of the pressure block 4 is approximately polygonal and the edge of the polygon is wavy. When the pressure block 4 presses against the inner frame paper of the cigarette pack, the surface of the pressure block 4 away from the cutter roller 1 can still imprint a groove on the surface of the inner frame paper. The wavy edge of the surface of the pressure block 4 away from the cutter roller 1 can increase the exposed area of ​​the fiber layer or the bottom layer material of the inner frame paper when cutting the coating on the surface of the inner frame paper, further enhancing the adhesion between the latex and the paper.

[0042] Furthermore, the surface of the pressure block 4 away from the knife roller 1 is provided with protrusions. When the pressure block 4 presses against the inner frame paper of the cigarette pack to imprint the groove, since the protrusions protrude from the surface of the pressure block 4 away from the knife roller 1, they can further squeeze the inner frame paper at the bottom of the groove, thereby damaging the coating on the bottom of the groove, increasing the roughness of the bottom of the groove, and exposing the fiber layer or the more easily bonded bottom material at the bottom of the groove. On the one hand, the latex contained in the groove can be more stably held inside the groove due to the influence of the rough bottom of the groove and the surface tension of the latex itself, thus increasing the amount of glue applied. On the other hand, the latex contained in the groove can directly contact the fiber layer or the more easily bonded bottom material exposed at the bottom of the groove and penetrate into the interior of the inner frame paper, thus enhancing the adhesion between the latex and the paper.

[0043] For example, the protrusion can be formed by a single continuous protrusion that forms a certain pattern (pattern, spiral pattern, etc.), or it can be composed of multiple protrusions spaced apart. It is only necessary to ensure that when the pressing block 4 presses against the inner frame paper of the cigarette pack to imprint the groove, the protrusion is far away from the surface of the pressing block 4 and cannot break the inner frame paper of the cigarette pack. Protrusions of different shapes can not only destroy the coating on the bottom surface of the groove, but also form different shaped patterns on the inner frame paper on the bottom surface of the groove, thereby improving the aesthetics.

[0044] In other embodiments, the surface of the pressure block 4 away from the knife roller 1 is provided with a set of blades that can cut glue lines into the inner frame paper or a set of needles that can pierce glue dots into the inner frame paper. In this case, not only can the surface of the pressure block 4 away from the knife roller 1 imprint grooves into the surface of the inner frame paper of the cigarette pack, the set of blades or needles on the surface of the pressure block 4 away from the knife roller 1 can also maximize the degree of damage to the coating on the surface of the inner frame paper and the degree of exposure of the fiber layer or the bottom layer material, so that the latex stays on the surface of the inner frame paper by relying on the surface roughness of the inner frame paper and the latex's adsorption capacity for the fiber layer or the bottom layer material.

[0045] Optionally, when the blade plate 2 is installed on the outer peripheral surface of the blade roller 1, the surface of the blade plate 2 near the blade roller 1 is in contact with the outer peripheral surface of the blade roller 1, and the surface of the blade plate 2 away from the blade roller 1 is parallel to the outer peripheral surface of the blade roller 1. The length of the cutting blade 3 along the axial direction of the blade roller 1 is greater than the width of the inner frame paper strip. The distance between the top of the cutting blade 3 and the surface of the blade plate 2 away from the blade roller 1 is greater than or equal to the thickness of the inner frame paper strip. When the blade roller 1 rotates, it can drive the blade plate 2 and the cutting blade 3 on it to rotate. The cutting blade 3 can cut the inner frame paper strip.

[0046] Furthermore, the outer circumferential surface of the cutter roller 1 is provided with a first mounting groove, and the cutter plate 2 is accommodated in the first mounting groove. The groove wall of the first mounting groove can abut against the side wall of the cutter plate 2. When the cutter plate 2 is installed in the first mounting groove, the side wall of the first mounting groove can play a guiding and positioning role to ensure that the installation angle of the cutter plate 2 is accurate. After the cutter plate 2 is installed in the first mounting groove, the side wall of the first mounting groove can play a limiting role to prevent the cutter plate 2 from shifting.

[0047] Furthermore, multiple blades 2 are arranged circumferentially along the blade roller 1. Each blade 2 is equipped with a cutting blade 3 and at least one pressure block 4. The cutting blades 3 on two adjacent blades 2 can cut the inner frame paper strip into a cigarette pack inner frame paper. The pressure block 4 between two adjacent cutting blades 3 can imprint grooves on the surface of the cigarette pack inner frame paper. By setting only one cutting blade 3 on each blade 2, when any cutting blade 3 is damaged, the damaged cutting blade 3 can be replaced by replacing its unique corresponding blade 2 without replacing other undamaged cutting blades 3, thus reducing maintenance costs. By setting multiple pressure blocks 4 on each blade 2, multiple grooves can be imprinted on the surface of the cigarette pack inner frame paper to form multiple adhesive areas, further enhancing the adhesion between the latex and the paper.

[0048] For example, the shape of the cutting blade 3 corresponds to the outer contour of the inner frame paper of the cigarette pack. Different shapes of cutting blades 3 can be set on different blade plates 2, and users can choose according to the required inner frame paper of the cigarette pack. The arrangement of the pressing block 4 on the blade plate 2 corresponds to the shape of the inner frame paper of the cigarette pack and the position of the pasting point. Different arrangements of pressing blocks 4 can be set on different blade plates 2, and users can choose according to the shape of the inner frame paper of the cigarette pack and the position of the pasting point.

[0049] In some embodiments, the first mounting groove is an annular groove extending along the axial direction of the cutter roller 1. The length of the annular groove along the axial direction of the cutter roller 1 is equal to the length of the blade plate 2 along the axial direction of the cutter roller 1, so that the inner sidewall of the annular groove can abut against the two sidewalls of the blade plate 2 opposite to each other along the axial direction of the cutter roller 1. The sidewalls of two adjacent blade plates 2 fit together without gaps, which not only increases the number of blade plates 2 that can be installed on the cutter roller 1 to improve cutting efficiency, but also further reduces the difficulty of positioning and installing the blade plates 2.

[0050] Furthermore, the inner frame paper cutting knife of the cigarette pack also includes a connector. The blade 2 is provided with a connecting hole 21. The connector can pass through the connecting hole 21 and be detachably connected to the blade roller 1 to detachably fix the blade 2 to the blade roller 1.

[0051] For example, the bottom surface of the first mounting groove is provided with a threaded hole, and the connecting part is a bolt. When the blade plate 2 is installed on the blade roller 1, the screw passes through the connecting hole 21 and engages with the threaded hole, and the screw head abuts against the surface of the blade plate 2 away from the blade roller 1. Multiple connecting holes 21 are provided at intervals, and the threaded holes are provided one-to-one with the connecting holes 21, which can improve the connection stability between the blade plate 2 and the blade roller 1. The connecting hole 21 is a countersunk hole. When fixed, the bolt will not protrude from the surface of the blade plate 2 away from the blade roller 1, so as to avoid affecting the cutting of the inner frame paper strip by the cutting blade 3.

[0052] In other embodiments, a first locking tongue assembly is provided in the first mounting groove, and the connector is a pin. When the blade plate 2 is installed on the blade roller 1, one end of the pin abuts against the surface of the blade plate 2 away from the blade roller 1, and the other end of the pin is locked by the locking tongue assembly.

[0053] Furthermore, the pressure block 4 is detachably connected to the blade plate 2. This not only allows for targeted repairs when the pressure block 4 is damaged or the protrusions on the pressure block 4 are damaged, without having to replace the entire blade plate 2, thus reducing maintenance costs, but also allows for the replacement of pressure blocks 4 of different thicknesses to accommodate inner frame paper of different thicknesses of cigarette packs or to imprint grooves of different depths on the surface of the inner frame paper of cigarette packs, or to imprint different shaped textures on the bottom surface of the grooves in the inner frame paper of cigarette packs by replacing pressure blocks 4 with protrusions of different shapes.

[0054] Furthermore, the surface of the blade 2 away from the blade roller 1 is provided with mounting holes 22, and the surface of the pressure block 4 near the blade 2 is provided with mounting posts. The mounting posts can be inserted into the mounting holes 22 and are detachably connected to the mounting holes 22. This arrangement avoids the need to provide other structures on the surface of the pressure block 4 away from the blade 2, thereby avoiding any adverse effects on the process of pressing the inner frame paper of the cigarette pack against the surface of the pressure block 4 away from the blade 2 to imprint grooves.

[0055] In some embodiments, the mounting post and the mounting hole 22 are interference-fitted. The mounting post is inserted into the mounting hole 22 to fix the pressure block 4 and the blade plate 2. The mounting post is pulled out of the mounting hole 22 to separate the pressure block 4 and the blade plate 2, thereby realizing the detachable connection between the pressure block 4 and the blade plate 2. Furthermore, during the process of the pressure block 4 pressing against the inner frame paper of the cigarette pack, the pressure between the pressure block 4 and the inner frame paper of the cigarette pack can also stabilize the interference fit between the mounting post and the mounting hole 22, thereby improving the connection stability between the pressure block 4 and the blade plate 2.

[0056] In other embodiments, a second locking tongue assembly is provided on the blade plate 2, and when the pressure block 4 is installed on the blade plate 2, the end of the mounting post away from the pressure block 4 is locked by the locking tongue assembly.

[0057] Optionally, a second mounting groove is provided on the surface of the blade plate 2 away from the blade roller 1. The mounting hole 22 is provided on the bottom surface of the second mounting groove. The side wall of the second mounting groove can abut against the side wall of the pressure block 4. When the pressure block 4 is installed in the second mounting groove, the side wall of the second mounting groove can play a guiding and positioning role to ensure that the installation angle of the pressure block 4 is accurate. After the pressure block 4 is installed in the second mounting groove, the side wall of the second mounting groove can play a limiting role to prevent the pressure block 4 from shifting.

[0058] Furthermore, the inner frame paper cutting knife of the cigarette pack also includes a dotted line knife 5, which is disposed on the surface of the knife plate 2 away from the knife roller 1, and is used to cut dotted lines in the inner frame paper of the cigarette pack. The dotted lines can serve as fold lines for the inner frame paper of the cigarette pack.

[0059] Furthermore, the cutter roller 1 includes a body 11 and a drive shaft 12. The drive shaft 12 is configured as two and located at both ends of the body 11 along the axis. The drive shaft 12 can be connected to the drive mechanism. The first mounting groove is provided in the body 11. The drive mechanism drives the drive shaft 12 to rotate so as to drive the body 11 to rotate, thereby driving the cutter plate 2 and the cutting blade 3 provided in the first mounting groove to rotate so as to cut the inner frame paper strip.

[0060] For example, a keyway is provided at the end of the drive shaft 12. When the drive shaft 12 is connected to the drive mechanism, a flat key can be installed in the keyway to transmit torque so that the drive shaft 12 can rotate smoothly.

[0061] This utility model also provides a cigarette pack inner frame paper rolling cutter, including a drive mechanism and the cigarette pack inner frame paper rolling cutter described in the embodiments of this utility model. Specifically, the drive mechanism is connected to the drive shaft 12 by a key to transmit torque so that the rotating shaft 6 can rotate smoothly, thereby driving the cutter roller 1 to rotate, which in turn drives the cutter plate 2 and the cutting blade 3 on it to rotate to cut the inner frame paper strip.

[0062] For example, the cigarette pack inner frame paper roll cutter also includes a conveying mechanism for conveying the inner frame paper strip in a direction perpendicular to the axis of the cutter roller 1. The width of the cigarette pack inner frame paper formed by cutting the inner frame paper strip can be controlled by controlling the conveying speed of the conveying mechanism and the rotation speed of the cutter roller 1.

[0063] Optionally, the conveying mechanism includes a conveyor belt and a drive wheel. The conveyor belt is wrapped around the drive wheel and can carry and convey the inner frame paper strip. The drive wheel rotates to drive the conveyor belt to move in a direction perpendicular to the axis of the cutter roller 1, thereby realizing the conveying of the inner frame paper strip.

[0064] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations 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.
