Description

Technical Field

[0001] This utility model relates to the technical field of cigarette production equipment, specifically to a cigarette metal belt traction device. Background Technology

[0002] Electromagnetically heated cigarettes are a new type of cigarette that incorporates an electromagnetic induction sensor within the cigarette. When the tobacco comes into contact with the sensor, the sensor heats up under the influence of electromagnetic induction, thereby heating the tobacco to produce smoke, which is then inhaled. The sensor is commonly made of metal and is typically distributed within the cigarette in granular or strip-like forms. The strip-shaped sensor is wrapped around the middle of the cigarette stick. During cigarette manufacturing, the tobacco stick and sensor must be moved synchronously. However, current technologies usually involve manually pulling the sensor, a process that is uncontrollable, unstable, and poses safety risks. Utility Model Content

The traction assembly includes a traction roller, a pressure roller, and a motor for driving the traction roller to rotate. The pressure roller is rotatably mounted on a pressure shaft, which is parallel to the rotation axis of the traction roller. A cylinder is arranged beside the pressure shaft and is connected to the pressure shaft. The cylinder extends and retracts to drive the pressure roller to move closer to or away from the traction roller.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0022] Please see Figures 1 to 3 A cigarette metal strip traction device for moving a metal strip includes at least one traction assembly. The traction assembly includes a traction roller 10 and a pressure roller 21. The traction roller 10 rotates under the drive of a motor 30. The pressure roller 21 is rotatably mounted on a pressure shaft 22. The pressure shaft 22 moves under the drive of a cylinder 40, causing the pressure roller 21 to move closer to or away from the traction roller 10. When the pressure roller 21 moves closer to the traction roller 10, the metal strip is clamped between the pressure roller 21 and the traction roller 10. The rotation of the traction roller 10 drives the pressure roller 21 to rotate. The traction roller 10 and the pressure roller 21 cooperate to move the metal strip, thereby achieving traction.

[0023] A traction roller 10 is mounted on a base 50, which provides a mounting foundation for the traction assembly. The traction roller 10 includes a centrally located roller shaft 12 and a traction wheel 11 coaxially sleeved around the roller shaft 12. The traction roller 10 is rotatably mounted on the base 50 via bearings. A motor 30 is fixedly mounted on the base 50. A drive gear 61 is mounted on the output shaft of the base 50, and a driven gear 62 is mounted at the end of the roller shaft 12. A transmission chain 63 is wound around the drive gear 61 and the driven gear 62. The motor 30 drives the driven gear 62 to rotate via the drive gear 61 and the transmission chain 63, thereby driving the roller shaft 12 and its traction wheel 11 to rotate. The driven gear 62 and the traction wheel 11 are fixedly mounted at both ends of the roller shaft 12, so that the driven gear 62 and the traction wheel 11 are located on opposite sides of the base 50, preventing the gear and the traction wheel 11 from being on the same side and affecting the movement of the metal strip.

[0024] A connecting rod 41 is also provided on the base 50. The middle part of the connecting rod 41 is rotatably connected to the base 50 via a pin. A pressure shaft 22 is fixedly provided at one end of the connecting rod 41. The pressure shaft 22 is set parallel to the roller shaft 12. The pressure roller 21 is rotatably sleeved on the pressure shaft 22. A cylinder 40 is fixedly provided on the base 50. The piston of the cylinder 40 is rotatably connected to the other end of the connecting rod 41. The extension and retraction of the cylinder 40 causes the connecting rod 41 to swing, which in turn causes the pressure roller 21 at the other end to swing, so that the pressure roller 21 moves closer to or away from the traction roller 10. After the pressure roller 21 approaches the traction roller 10, the metal strip is clamped between the pressure roller 21 and the traction roller 11. The pressure roller 21 applies pressure to the metal strip, so that the metal strip is tightly attached to the metal strip. The traction roller 10 rotates, and the friction between the traction roller 11 and the metal strip drives the metal strip to move, thereby realizing the traction of the metal strip.

[0025] A guide groove 111 is provided on the outer circular surface of the traction wheel 11. The guide groove 111 is an annular groove and is arranged around the outer circular surface of the traction wheel 11. During traction, the metal belt is located in the guide groove 111. The inner wall of the guide groove 111 forms a stop on the side of the metal belt, which can prevent the metal belt from being deviated relative to the traction wheel 11 by external force, thus preventing the metal belt from detaching from the traction wheel 11 and causing ineffective traction.

[0026] Correspondingly, the pressure roller 21 is provided with an outwardly protruding rib 211, which is arranged around the outer circumference of the pressure roller 21 and corresponds to the guide groove 111. The pressure roller 21 contacts the metal strip through the rib 211. When the pressure roller 21 approaches the traction roller 10, the rib 211 squeezes the metal strip, pressing the metal strip into the guide groove 111. The metal strip is positioned between the guide groove 111 and the rib 211.

[0027] Furthermore, a grid pattern is provided on the inner wall of the bottom of the guide groove 111 to increase the friction of the bottom surface of the guide groove 111.

[0028] Furthermore, both the roller 12 and the traction wheel 11 are made of steel to improve the structural strength of the traction roller 10, provide effective support for the metal belt, and prevent the metal belt from changing its traction direction or bending and deforming due to insufficient strength of the traction roller 10 during the movement of the metal belt.

[0029] Furthermore, the pressure roller 21 is a rubber roller to prevent damage to the metal belt under pressure and to protect the metal belt.

[0030] As another implementation, multiple sets of traction components are spaced apart along the direction of movement of the metal belt to provide power for the movement of the metal belt. At the same time, multiple sets of traction devices provide support for the metal belt to prevent the metal belt from bending and deforming due to its own weight or external forces during movement.

[0031] The pressure applied to the metal belt by the pressure roller 21 can be controlled by changing the extension and retraction of the cylinder 40, so as to adjust the friction between the metal belt and the traction roller 11 and ensure that the rotation of the traction roller 10 drives the metal belt to move. When the extension and retraction of the cylinder 40 changes, the distance between the pressure roller 21 and the traction roller 11 also changes, which can clamp metal belts of different thicknesses and sizes, and is suitable for traction of metal belts of different sizes.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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; and these 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.
