Description

Technical Field

[0001] This utility model relates to a cigarette production equipment, and more specifically, to an independent drive device for the side sealing soldering iron of the transparent paper of a cigarette packaging machine. Background Technology

[0002] The heat-sealing principle of the transparent paper side of the small box is basically the same for mainstream cigarette packaging equipment. The process is as follows: after the small box and a single sheet of transparent paper meet, they enter the forming wheel component at the CH section. The rotation of the forming wheel folds the transparent paper, with both ends overlapping the side of the small box. Under the action of the forming wheel, the small box, carrying the folded transparent paper, rotates and moves forward. The side of the small box is in close contact with the arc plate above the forming wheel. The lower side of the heat-sealing iron on the arc plate above the forming wheel and the inner side of the arc plate are located in the same arc surface, and its working surface contacts the overlapping area of ​​the transparent paper on the side of the small box. After ironing, the overlapping transparent paper melts and adheres due to heat. The iron moves slightly vertically under the action of the cam and connecting spring, allowing the ironed small box to continue moving smoothly forward under the action of the rotating forming wheel, entering the next process. Because the movement of the heat-sealing iron on the side of the cigarette packaging box is controlled by mechanical structures such as cam linkages, and the ironing time of the iron on the overlap of the transparent paper of the box is inversely proportional to the running speed of the equipment, when the equipment enters a slow running state, it is very easy to cause quality problems such as dents in the box body and burnt cigarettes. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model proposes an independent drive device for the side-sealing soldering iron of the transparent paper in a cigarette packaging machine. This device aims to ensure the heat-sealing quality of the overlapping area of ​​the transparent paper side of the cigarette packaging machine using the side-sealing soldering iron, thereby avoiding product quality problems caused by heat sealing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An independent drive device for a side-sealing soldering iron on a cigarette packaging machine is provided. The small box is placed in a mold on the outer circumference of a forming wheel and rotates synchronously with the forming wheel. Transparent paper covers the outer surface of the small box, with both ends overlapping the sides of the small box. The overlapping area is exposed and heat-sealed through contact with the working surface of the side-sealing soldering iron. Two side-sealing stations are provided along the rotation path of the small box, corresponding to the positions of adjacent small boxes on the forming wheel. An arc-shaped plate, coaxial with the forming wheel, covers the periphery of the forming wheel containing the small boxes. At each side-sealing station, a side-sealing soldering iron mounted on a bracket passes through a pre-reserved opening on the arc-shaped plate and moves back and forth, switching between its original position and the side-sealing position. When the working surface of the side-sealing soldering iron is in its original position, a gap is maintained between it and the small box. When in the side-sealing position, it faces and contacts the overlapping area of ​​the transparent paper of the small box passing through the side-sealing station. Its structural features are: The independent drive device for the side sealing soldering iron of the small box transparent paper of the cigarette packaging machine is used to drive the side sealing soldering iron to move back and forth. It includes a drive mechanism, a power output shaft with the central axis parallel to the forming wheel shaft, a drive sector gear, a first driven sector gear, a second driven sector gear, a first booster shaft, and a second booster shaft. The power output shaft is driven by a drive mechanism, which drives the axle of the coaxially connected driving sector gear to reciprocate around the central axis. The driving sector gear has a driving gear segment. The first driven sector gear and the second driven sector gear have the same structural form. The two first driven gear segments on the first driven sector gear and the two second driven gear segments on the second driven sector gear are evenly spaced circumferentially. The driving sector gear, the first driven sector gear, and the second driven sector gear mesh sequentially. The axle of the first driven sector gear is connected to the first... The booster shaft is coaxially connected, and the axle of the second driven sector gear is coaxially connected to the second booster shaft. The first booster shaft and the second booster shaft are respectively connected to the brackets of a pair of side-sealing soldering irons. The first booster shaft moves synchronously with the first driven sector gear, and the second booster shaft rotates synchronously with the second driven sector gear. They can either be raised to the initial position or lowered to the working position. By switching from the initial position to the working position, the brackets drive the pair of side-sealing soldering irons to the side-sealing position. By resetting from the working position to the initial position, the brackets drive the pair of side-sealing soldering irons to their original positions.

[0005] The structural features of this utility model also lie in: The drive mechanism includes a linear motor, a push rod, a universal joint, and a connecting member. The push rod is connected between the output end of the linear motor and the input end of the universal joint. The output end of the universal joint is connected to the connecting member. One end of the connecting member is connected to the power output shaft. The linear motor drives the push rod to reciprocate linearly. The push rod drives the connecting member and the power output shaft to reciprocate around the central axis of the power output shaft through the universal joint.

[0006] The connector is a V-shaped rod structure with its open side facing the forming wheel. One end of the connector facing the push rod is connected to the output end of the universal joint, and the other end on the same side is connected to the power output shaft.

[0007] The bracket is provided with a limiting block, which is located on the outside of the convex surface of the arc plate. When the side sealing soldering iron is in the side sealing position, it is in contact with the convex surface of the arc plate, and when the side sealing soldering iron is in the original position, there is a gap between it and the convex surface of the arc plate.

[0008] Compared with existing technologies, the beneficial effects of this utility model are reflected in: This invention provides driving force through a drive mechanism, which is driven by a power output shaft. Through the sequential meshing of a driving sector gear, a first driven sector gear, and a second driven sector gear, a pair of side-sealing soldering irons are moved back and forth using a first and second booster shaft, achieving switching between the original position and the side-sealing position. Compared with the traditional mode of operation controlled by mechanical structures such as cam linkages, this invention reduces the cam transmission link, enabling more precise movement of the side-sealing soldering irons. The linear motor in the drive mechanism can cooperate with a PLC module and encoder to achieve flexible control of the movement of the side-sealing soldering irons, better match different operating speeds of the equipment, avoid over-ironing, and eliminate product quality problems caused by over-ironing.

Detailed Implementation

[0011] 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 in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0012] The small box is placed in the mold box 11 on the outer circumference of the forming wheel 1 and rotates synchronously with the forming wheel 1. Transparent paper covers the outer surface of the small box, with both ends overlapping the sides of the small box. The overlapping area is exposed and heat-sealed by contact with the working surface of the side-sealing soldering iron 22. Two side-sealing stations are provided along the rotation path of the small box, corresponding to the positions of adjacent small boxes on the forming wheel 1. An arc-shaped plate 12, coaxial with the forming wheel 1, covers the outer periphery of the forming wheel 1 containing the small box. At each side-sealing station, the side-sealing soldering iron 22, mounted on the bracket 21, passes through the reserved opening 121 on the arc-shaped plate 12 and moves back and forth, switching between its original position and the side-sealing position. When the working surface of the side-sealing soldering iron 22 is in its original position, a gap is maintained between it and the small box. When in the side-sealing position, it faces and contacts the overlapping area of ​​the transparent paper of the small box passing through the side-sealing station. (See also...) Figures 1 to 3 The independent drive device for the side sealing soldering iron 22 of the small box transparent paper of the cigarette packaging machine in this embodiment is used to drive the side sealing soldering iron 22 to move back and forth. It includes a drive mechanism, and also includes a power output shaft 41 with the central axis parallel to the wheel axle of the forming wheel 1, a driving sector gear 42, a first driven sector gear 45, a second driven sector gear 44, a first booster shaft 45, and a second booster shaft 46. The power output shaft 41 is driven by a drive mechanism, which drives the axle of the coaxially connected drive sector gear 42 to reciprocate around the central axis. The drive sector gear 42 has a drive gear segment 421. The first driven sector gear 45 and the second driven sector gear 44 have the same structure. The two first driven gear segments 431 on the first driven sector gear 45 and the two second driven gear segments 441461 on the second driven sector gear 44 are evenly spaced circumferentially. The drive sector gear 42, the first driven sector gear 45, and the second driven sector gear 44 mesh sequentially. The axle of the first driven sector gear 45 and the... The first booster shaft 45 is coaxially connected, and the axle of the second driven sector gear 44 is coaxially connected to the second booster shaft 46. The first booster shaft 45 and the second booster shaft 46 are respectively connected to the bracket 21 of a pair of side-sealing soldering irons 22. The first booster shaft 45 moves synchronously with the first driven sector gear 45, and the second booster shaft 46 rotates synchronously with the second driven sector gear 44. They can either be raised to the initial position or lowered to the working position. By switching from the initial position to the working position, the bracket 21 drives the pair of side-sealing soldering irons 22 to the side-sealing position. By resetting from the working position to the initial position, the bracket 21 drives the pair of side-sealing soldering irons 22 to the original position.

[0013] In specific implementation, the corresponding structural configuration of the device also includes: The drive mechanism includes a linear motor 31, a push rod 32, a universal joint 33, and a connecting member 34. The push rod 32 is connected between the output end of the linear motor 31 and the input end of the universal joint 33. The output end of the universal joint 33 is connected to the connecting member 34. One end of the connecting member 34 is connected to the power output shaft 41. The linear motor 31 drives the push rod 32 to reciprocate linearly. The push rod 32 drives the connecting member 34 and the power output shaft 41 to reciprocate around the central axis of the power output shaft 41 through the universal joint 33.

[0014] Linear motor 31 is connected to and controlled by PLC.

[0015] The connector 34 has a V-shaped rod structure, with the side of the opening 121 facing the forming wheel 1. The end facing the push rod 32 is connected to the output end of the universal joint 33, and the end on the same side is connected to the power output shaft 41.

[0016] The model number of the universal joint 33 is SFG 10.22.

[0017] The bracket 21 is provided with a limiting block 23, which is located outside the convex surface of the arc plate 12. When the side sealing soldering iron 22 is in the side sealing position, it is in contact with the convex surface of the arc plate 12. When the side sealing soldering iron 22 is in the original position, there is a gap between it and the convex surface of the arc plate 12. It is used to limit the side sealing soldering iron 22 when it switches from the original position to the side sealing position.

[0018] The following is the working process of this device: Driven by the drive mechanism, the power output shaft 41 reciprocates, and the driving sector gear 42 reciprocates synchronously. During the rotation, the meshing transmission between the driving sector gear 42 and the first driven sector gear 45, and the meshing transmission between the first driven sector gear 45 and the second driven sector gear, drive the first driven sector gear 45 and the second driven sector gear 44 to reciprocate synchronously through their respective axles. The first driven sector gear 45 and the second driven sector gear 44 drive the first booster shaft 45 and the second booster shaft 46 to reciprocate synchronously through their respective axles. The first booster shaft 45 and the second booster shaft 46 drive a pair of brackets 21 to reciprocate around the central axis of their respective shafts. This reciprocating swing causes the side sealing soldering irons 22 on the pair of brackets 21 to be raised or lowered synchronously. After being raised, the side sealing soldering iron 22 returns to its original position, and after being lowered, the side sealing soldering iron 22 reaches the side sealing position. Thus, the side sealing soldering iron 22 can be switched between its original position and the side sealing position.

[0019] Further extensions based on this embodiment: The movement of the side-sealing soldering iron 22 can be adjusted by using a PLC program to control the linear motor 31 in the drive mechanism to match different speeds of the forming wheel 1. For example, when the speed is not less than 30 packs / minute, the linear motor 31 drives the side-sealing soldering iron 22 to remain in the side-sealing position; when the speed is less than 30 packs / minute, when the phase of the forming wheel 1 reaches 156°, the linear motor 31 drives the side-sealing soldering iron 22 to remain in the side-sealing position for 0.6 seconds, and then the linear motor 31 drives the side-sealing soldering iron 22 to lift it back to its original position, stopping the ironing of the overlapping area of ​​the small box transparent paper.

[0020] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
