[0026] The utility model provides a kind of cigarette machine with stable conveying function, which is described in detail below in combination with specific embodiments and application scenarios. Figures 1-2

[0027] As shown in Figure 1 The utility model provides a kind of cigarette machine with stable conveying function, which includes: rack 1, driving part, conveying roller 2 and friction roller 3. Driving part is installed in rack 1. The driving end of driving part is connected with conveying roller 2. Friction roller 3 is rollably arranged in rack 1. The roller surface of conveying roller 2 is provided with anti-skid assembly. Friction roller 3 and anti-skid assembly are in frictional contact. With the rotation of driving part, friction roller 3 and conveying roller 2 move towards each other, conveying the cigarette paper 100 clamped between friction roller 3 and conveying roller 2 to the gumming station 4 of cigarette machine.

[0028] ​It can be understood that the conveying roller 2 and the friction roller 3 are located on the cigarette paper 100 conveying station. The driving member can be a servo motor. The driving member is installed on the rack 1. The output end of the driving member is connected with the conveying roller 2 to drive the conveying roller 2 to rotate. The friction roller 3 is rollably arranged on the rack 1 and oppositely arranged with the conveying roller 2. The cigarette paper 100 is clamped between the roller surface of the conveying roller 2 and the roller surface of the friction roller 3. Under the driving of the driving member, the conveying roller 2 rotates at a certain rotating speed. The friction roller 3 is in contact with the conveying roller 2, and the friction roller 3 rolls relative to the rack 1 under the transmission force of the conveying roller 2. The friction roller 3 and the conveying roller 2 rotate towards each other, so that the cigarette paper 100 is conveyed to the gluing station 4.

[0029] Further, as shown in Figure 2 The roller surface of the conveying roller 2 is provided with an anti-skid assembly. By arranging the anti-skid assembly on the roller surface of the conveying roller 2, the friction between the conveying roller 2, the cigarette paper 100 and the friction roller 3 is increased. The anti-skid assembly can not only increase the friction transmission force of the conveying roller 2 and the friction roller 3 on the cigarette paper 100, but also prevent the cigarette paper 100 from slipping, so as to ensure that the cigarette paper 100 is smoothly conveyed to the gluing station 4, guarantee the accuracy of the glue point position of the cigarette paper 100 and ensure the stability of the cigarette paper 100 when cutting.

[0030] The utility model provides a kind of cigarette making machine with stable conveying function, the driving end of driving member and conveying roller 2 connect, to drive conveying roller 2 rotate, friction roller 3 can be rollably arranged in rack 1 and contact with conveying roller 2, friction roller 3 rolls under the transmission force of conveying roller 2, friction roller 3 and conveying roller 2 move towards each other, so that the cigarette paper 100 clamped between friction roller 3 and conveying roller 2 is conveyed to the gluing station 4 of cigarette making machine;At the same time, the roller surface of conveying roller 2 has anti-skid assembly, friction roller 3 and anti-skid assembly friction contact, anti-skid assembly can increase the friction of conveying roller 2 on cigarette paper 100, ensure that cigarette paper 100 does not slip, so that cigarette paper 100 is smoothly conveyed to gluing station 4 and cutting station, anti-skid assembly can also increase the friction between conveying roller 2 and friction roller 3, ensure that conveying roller 2 and friction roller 3 have enough friction transmission force on cigarette paper 100.

[0031] Specifically, as shown in Figure 2 The conveying roller 2 is divided into middle region 21 and edge region 22. The outer diameter of the middle region 21 is smaller than that of the edge region 22, and the anti-skid assembly includes a first anti-skid structure 211. The first anti-skid structure 211 is arranged on the middle region 21. The first anti-skid structure 211 is used to contact the cigarette paper 100. The middle part of the friction roller 3 is used to press the cigarette paper 100.

[0032] Understandably, the cigarette paper 100 overlaps the middle region 21 of the conveyor roller 2. The size of the middle region 21 of the conveyor roller 2 is smaller than the size of its edge region 22. The outer diameter of the middle region 21 of the conveyor roller 2 is smaller than the outer diameter of the edge region 22, so as to limit the cigarette paper 100 at the junction of the middle region 21 and the edge region 22, ensuring that the cigarette paper 100 does not shift.

[0033] Generally, the surface of cigarette paper 100 is relatively smooth, especially when one side of cigarette paper 100 has an anti-permeability layer, the surface of cigarette paper 100 will be even smoother. Furthermore, the first anti-slip structure 211 is located in the middle region 21 of the conveyor roller 2, which can increase the friction between the conveyor roller 2 and the side of cigarette paper 100 with the anti-permeability layer. The friction roller 3 presses against the other side of cigarette paper 100, squeezing the cigarette paper 100, which can further increase the friction between the conveyor roller 2 and the cigarette paper 100, thereby preventing the cigarette paper 100 from shifting and ensuring that the cigarette paper 100 is accurately transported to the gluing station 4 and the cutting station.

[0034] In some embodiments, such as Figure 2 As shown, the anti-slip assembly also includes a second anti-slip structure 221. The depth of the second anti-slip structure 221 is less than the depth of the first anti-slip structure 211. The second anti-slip structure 221 is located in the edge region 22 and is used for frictional contact with the outer edge of the friction roller 3.

[0035] Understandably, the second anti-slip structure 221 is located on the edge area 22 of the conveying roller 2, and the edge area 22 of the conveying roller 2 is in direct contact with the outer edge of the friction roller 3. The second anti-slip structure 221 is used to increase the friction between the conveying roller 2 and the friction roller 3 to ensure that the cigarette paper 100 is not easy to slip.

[0036] In some embodiments, the first anti-slip structure 211 is a grid-like anti-slip texture.

[0037] And / or, the second anti-slip texture is a striped anti-slip texture.

[0038] Understandably, a special process can be used to divide the middle area 21 of the conveyor roller 2's surface into small grids or squares, forming protrusions and depressions between the grids, thereby creating a grid-like anti-slip texture. The grid-like anti-slip texture can increase the roughness of the middle area 21 of the conveyor roller 2's surface, improving the friction between it and the friction roller 3, thus reducing the possibility of the cigarette paper 100 sliding off course.

[0039] Similarly, a special process can be used to divide the edge area 22 of the conveyor roller 2's surface into a series of parallel stripes or raised patterns, thereby forming striped anti-slip patterns. These striped anti-slip patterns resemble the tread pattern of vehicle tires. The striped anti-slip patterns increase the additional friction between the conveyor roller 2 and the friction roller 3.

[0040] Of course, the first anti-skid structure 211 and the second anti-skid structure 221 can also be in any other form as long as the roller surface of the conveying roller 2 has sufficient friction, and the present application does not make specific limitations thereon. For example, the first anti-skid structure 211 and the second anti-skid structure 221 can both be grid-shaped anti-skid lines, wherein the grid distribution density of the second anti-skid structure 221 is less than that of the first anti-skid structure 211. The first anti-skid structure 211 can also be anti-skid protrusions punched on the surface of the conveying roller 2. The second anti-skid structure 221 can also be wave-shaped anti-skid lines.

[0041] In some embodiments, the roller surface of the conveying roller 2 is provided with a thermal spray layer.

[0042] It can be understood that the thermal spray layer can be sprayed on the roller surface of the conveying roller 2 by using a thermal spray technology. The thermal spray technology is a method of spraying coating materials on the surface of a substrate under high temperature conditions to form a protective coating or a functional coating on the surface of the substrate.

[0043] The thermal spray layer provided on the roller surface of the conveying roller 2 can improve the hardness of the surface of the conveying roller 2, improve the wear resistance of the conveying roller 2, and reduce the maintenance cost of the cigarette making machine.

[0044] In some embodiments, the color of the thermal spray layer is different from the color of the conveying roller 2. In this way, the user can intuitively see whether the thermal spray layer is scratched, so that the user can replace the conveying roller 2 when the conveying roller 2 is seriously worn, and always ensure the smooth conveying of the cigarette paper 100 by the conveying roller 2 and the friction roller 3, and ensure the stability of the gluing and cutting of the cigarette paper 100.

[0045] Optionally, the color of the thermal spray layer can be set as bright gold or red.

[0046] Preferably, the thermal spray layer is a titanium carbide layer.

[0047] The titanium carbide layer is a type of thermal spray layer. The titanium carbide layer has high hardness, wear resistance, corrosion resistance and other excellent properties, which greatly contributes to improving the wear resistance of the conveying roller 2.

[0048] In some embodiments, the cigarette making machine with the stable conveying function further comprises a bearing seat. The bearing seat is installed on the rack 1. The friction roller 3 is rollingly connected with the rack 1 through the bearing seat.

[0049] It can be understood that the bearing seat can provide support and positioning function for the installation of the friction roller 3. The bearing seat is installed on the rack 1 and close to the position of the conveying roller 2. The friction roller 3 is installed on the bearing seat. The bearing seat can not only provide support for the friction roller 3, but also enable the friction roller 3 and the conveying roller 2 to rotate towards each other after being subjected to the conveying force of the conveying roller 2, so as to realize the stable conveying of the cigarette paper 100 together.

[0050] Further, as shown in Figure 1 The friction roller 3 has a plurality of. The plurality of friction rollers 3 are arranged along the circumference of the conveying roller 2. Each friction roller 3 is rollably provided on the rack 1 by a bearing seat, and each friction roller 3 is in friction contact with the anti-skid assembly.

[0051] It can be understood that a plurality of friction rollers 3 are arranged along the circumference of the conveying roller 2. Each friction roller 3 is installed on the rack 1 by a bearing seat, and each friction roller 3 can be in relative friction with the conveying roller 2, so as to realize multi-stage friction conveying of the cigarette paper 100 on the conveying roller 2, and improve the friction conveying force of the cigarette paper 100.

[0052] Optionally, the number of friction rollers 3 can be two or three. The present application does not make specific limitation on this.

[0053] Further, the cigarette machine with stable conveying function further comprises a gluing member, a paper feeding roller, a cutting knife and a cutting roller. The gluing member is movably provided at the gluing station 4 and is used for gluing the cigarette paper 100. The paper feeding roller is used for conveying the glued cigarette paper 100. The cutting knife is installed on the cutting roller, and the paper feeding roller and the cutting roller move at the same speed and towards each other, so that the cutting knife cuts the cigarette paper 100.

[0054] It can be understood that the gluing member is located at the gluing station 4 and is used for gluing the cigarette paper 100. Based on the conveying of the conveying roller 2 and the friction roller 3 to the cigarette paper 100, the cigarette paper 100 will not be deviated at the gluing window, so as to ensure that the gluing member can uniformly cover the gluing on the surface of the cigarette paper 100, so as to facilitate the subsequent paper roll forming and cigarette manufacturing process.

[0055] Among them, the paper feeding roller is used for conveying the glued cigarette paper 100 to the cutting knife and the cutting roller. The function of the paper feeding roller is to ensure that the cigarette paper 100 can maintain appropriate tension and position during the entire processing process, and to ensure the accuracy and stability of cutting.

[0056] Furthermore, a cutting blade is mounted on a cutting roller for cutting the cigarette paper 100. The cutting roller is a support component for the cutting blade, assisting it in cutting the cigarette paper 100. The motors configured for the feeding roller and the cutting roller operate at the same speed but in opposite directions. During the process of the feeding roller and the cutting roller moving in opposite directions at the same speed, the cutting blade can accurately cut the cigarette paper 100, ensuring that the length and shape of the cigarette meet the requirements.

[0057] In a specific application scenario, the calculation process for the diameter of conveyor roller 2 is as follows:

[0058] Since the length L of the cigarette paper 100 required for each cigarette is the circumference of the cigarette plus a certain overlap, typically 2mm, different conveyor roller diameters 2 can be selected depending on the cigarette diameter to improve the production quality of the cigarette rolling machine. The cigarette diameter, the length L of the cigarette paper 100, and the diameter D of the conveyor roller 2 are all considered. 输 The relationship between them is as follows:

[0059]

[0060] For example, when the required diameter of the cigarette to be produced is 6.8mm to 7.1mm, that is, when L is 24mm,

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
