Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging machine technology, and in particular to a guide component. Background Technology

[0002] In a small-box packaging machine, the upright station is usually located at the front end of the conveyor belt inlet, which is located on the side of the drying wheel. A push rod is located on the other side of the drying wheel relative to the upright station. Correspondingly, after the small cigarette packs are pushed into the circumferentially spaced receiving chambers on the drying wheel, they are then conveyed circumferentially by the rotating drying wheel to the side of the upright station at the conveyor belt inlet. At this point, the push rod is controlled to move axially to push the small cigarette packs onto the upright station. Afterward, the push rod retracts axially, and the small cigarette packs are pushed from the upright station onto the conveyor belt.

[0003] The uprighting device is a pushing mechanism that can push and move the small cigarette pack along an arc path, gradually straightening it. (See attached instruction manual.) Figure 1 As shown, since the receiving chamber is tilted when it rotates to the conveyor belt inlet, the small cigarette packs inside are also tilted when pushed out by the push rod. When a small cigarette pack is pushed into the erecting station device by the push rod, the erecting station device is driven to push the small cigarette pack along an arc path toward the conveyor belt inlet. Since the erecting station device pushes the small cigarette pack along the arc path, the small cigarette pack can be adjusted to a vertical and non-tilted posture when it is pushed to the conveyor belt inlet, so as to avoid the small cigarette pack falling directly onto the conveyor belt in a tilted posture and tipping over, thus avoiding affecting the cigarette pack conveying.

[0004] In addition, limiting side plates are installed on the front and rear sides of the erecting station device. The distance between the front and rear side plates is usually equal to the length of the small cigarette pack, in order to guide the small cigarette pack to move towards the conveyor belt.

[0005] However, the front and rear side plates are fixed separately (the erecting station is movable, and the side plates cannot be fixedly connected to the erecting station). The distance between the front and rear baffles is usually not adjustable. However, even the same model of small cigarette packs will have reasonable deviations in their external dimensions (due to unavoidable processing errors, some small cigarette packs are 1-3mm longer than the standard size, and some are 1-3mm shorter than the standard size). This causes small cigarette packs with larger lengths to be directly blocked at the starting push position of the erecting station, or small cigarette packs with smaller lengths to move and get blocked on the arc-shaped push path when being pushed in the erecting station, resulting in blockage of the small pack packaging machine. Utility Model Content

[0006] To address the aforementioned technical problems in the existing technology, this utility model provides a small cigarette pack conveying and guiding assembly. The second guide plate of the first side plate can be pushed backward by the small cigarette pack, or automatically reset and move forward under the action of spring force, thereby cooperating with the second side plate to adaptively limit all small cigarette packs within a specific length range, preventing the small cigarette packs from blocking the vertical station device.

[0007] The technical solution of this utility model to solve the above problems is as follows: a small cigarette pack conveying and guiding assembly is provided, including a first side plate and a second side plate. The first side plate and the second side plate are arranged opposite to each other on both sides of the arc-shaped moving path of the small cigarette pack in the upright station device. The first side plate and the second side plate are both fixedly installed. The first side plate includes a first fixed plate and a second guide plate. The second guide plate includes a connecting end, a guide strip, and a guide shell. The second guide plate is connected to the first fixed plate through the connecting end. The connecting end is integrally connected to the guide strip. The guide strip is inserted into the guide shell. The outer wall surface of the guide shell facing the second side plate is a guide surface for contacting and guiding the movement of the small cigarette pack. The cavity width of the guide shell corresponding to the inner cavity of the shell into which the guide strip is inserted is greater than the thickness of the guide strip. A spring is also connected between the side wall of the guide strip facing the second side plate and the cavity wall of the inner cavity of the shell facing away from the second side plate.

[0008] Furthermore, the inner cavity of the housing has a first housing opening and a second housing opening. The first housing opening is disposed on both sides of the guide shell opposite to the guide surface. The cavity width of the inner cavity is the distance from the first housing opening to the inner wall of the cavity closest to the guide surface. The guide strip is inserted into the inner cavity of the housing from the second housing opening.

[0009] Furthermore, the guide shell includes a shell cover and a shell body having the inner cavity of the shell. The shell cover is detachably fitted at the first shell opening by a bolted connection structure.

[0010] Furthermore, one end of the first fixing plate is fixedly installed, and the other end is provided with a connecting slope. The connecting slope is inclined relative to the second side plate. The second guide plate is connected to different positions on the connecting slope so that the second guide plate and the second side plate have different distances.

[0011] Furthermore, one end of the second side plate is fixedly installed, and the distance from the other end to the starting point of the arc-shaped movement path of the small cigarette pack within the erecting station device is greater than the thickness of one small cigarette pack.

[0012] Furthermore, a first screw hole is provided on the connecting inclined surface of the first fixing plate, and a strip-shaped through hole is provided on the end of the second guide plate corresponding to the connection of the first fixing plate. The guide plate also includes a first bolt that passes through the strip-shaped through hole and is threadedly connected to the first screw hole. The first bolt is used to fix the first fixing plate and the second guide plate. The first bolt is also threadedly connected to the first screw hole at different positions of the strip-shaped through hole to limit the second guide plate at different positions on the connecting inclined surface, thereby making the second guide plate and the second side plate have different distances.

[0013] Furthermore, the first screw hole is positioned perpendicular to the connecting inclined surface.

[0014] Furthermore, the edge of the connecting slope that is closest to the second side plate is the upper edge of the connecting slope.

[0015] Furthermore, it also includes a third adjusting plate, which is integrally disposed on the upper end of the second guide plate and extends above the second side plate. The third adjusting plate is also vertically perforated with a second screw hole, and a second bolt is disposed at the second screw hole. The second bolt passes downward through the second screw hole to abut against the upper end face of the second side plate. When the first bolt cooperates with the first fixing plate to clamp the second guide plate at the current position of the connecting inclined surface, the second bolt moves upward or downward by rotating through the thread and also abuts against the upper end face of the second side plate, so that the second guide plate can be stably suspended at the current position.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The following will be based on Figures 1-7 The present invention provides a detailed description of the small cigarette pack conveying and guiding component.

[0022] Please see Figure 1 ,by Figure 1 Taking the indicated direction as an example, Figure 1 This is a part of the structure of the small box packaging machine mentioned in the background art. It mainly includes a drying wheel 11, a push rod mechanism 12, a conveyor belt device 13, and a vertical station device 14. The push rod mechanism 12 is installed on the left front side of the drying wheel 11, the conveyor belt device 13 is located on the left rear side of the drying wheel 11, and the vertical station device 14 is also located on the left rear side of the drying wheel 11 and at the right front end of the conveyor belt device 13. The vertical station device 14 is also arranged opposite to the push rod mechanism 12.

[0023] like Figure 1 As shown, the drying wheel 11 has several accommodating chambers evenly arranged on its outer periphery. Both the front and rear ends of the accommodating chambers are open, and each accommodating chamber can accommodate a small cigarette pack. When the drying wheel 11 is driven to rotate, when the accommodating chamber containing the small cigarette pack rotates to the rear side of the push rod mechanism 12, the push rod mechanism 12 will operate to push the small cigarette pack onto the vertical station device 14. After receiving the small cigarette pack, the vertical station device 14 will operate to transfer the small cigarette pack to the left and transport it to the right input port of the conveyor belt device 13. The small cigarette pack is then transported to the next process equipment via the conveyor belt device 13.

[0024] Please see Figure 1 and Figure 2 The erecting station device 14 is used to transport small cigarette packs that are pushed out of the receiving chamber and tilted to the right to the right input port of the conveyor belt device 13. It also adjusts the tilted cigarette packs to an upright position. Therefore, the movement trajectory of the cigarette pack conveying platform of the erecting station device 14 is an arc.

[0025] For this, please refer to Figure 1 and Figure 2 ,by Figure 1Taking the orientation shown as an example, when the pusher mechanism 12 pushes the small cigarette packs in the receiving chamber into the small cigarette pack conveying platform of the vertical station device 14 in sequence, in order to prevent the body of the small cigarette pack from being exposed at the rear end of the small cigarette pack conveying platform due to the pusher mechanism 12 extending too far, and to prevent the small cigarette pack from being unable to smoothly enter the conveyor belt device 13 due to part of its body being exposed at the edge of the small cigarette pack conveying platform, limit plates are usually set on the front and rear sides of the vertical station device 14 to limit the displacement of the small cigarette pack in the front and rear direction on the small cigarette pack conveying platform, and guide the small cigarette pack to move steadily towards the right input port of the conveyor belt device 13, thus restricting the movement of the small cigarette pack during the process of being conveyed along the arc trajectory.

[0026] However, traditional limiting plates are simply separate plate structures, usually directly fixed in place. Therefore, if the push rod mechanism 12 extends too far backward, it will push the small cigarette pack against the rear limiting plate, causing the pack to be squeezed and deformed. Furthermore, the constant distance between the front and rear limiting plates only provides good guiding and limiting for a specific type of cigarette pack; it cannot reliably guide and limit other types of cigarette packs or those with different lengths.

[0027] For this, please refer to Figure 3 and Figure 4 This embodiment of a small cigarette pack conveying and guiding assembly includes a first side plate 2 and a second side plate 3. The first side plate 2 and the second side plate 3 are arranged opposite to each other. The first side plate 2 is located on the rear side of the erecting station device 14, and the second side plate 3 is located on the front side of the erecting station device 14. The first side plate 2 is fixedly installed on the body structure of the conveyor belt device 13, and the second side plate 3 is fixedly installed on the side of the arc-shaped limiting plate above the erecting station device 14. The first side plate 2 includes a first fixed plate 21 and a second guide plate 22. The left end of the first fixed plate 21 is fixedly installed on the body structure of the conveyor belt device 13. The second guide plate 22 includes a connecting end 221, a guide strip 222, and a guide shell 223. The second guide plate 22 is connected to the right end of the first fixed plate 21 through the connecting end 221. The connecting end 221 is integrally connected with the guide strip 222. The guide strip 222 is inserted into the guide shell 223. The outer wall surface of the guide shell 223 facing the front is a smooth guide surface for contacting and guiding the movement of the small cigarette pack. The cavity width of the guide shell 223, which is used for the inner cavity 225 of the housing to which the guide strip 222 is inserted, is greater than the thickness of the guide strip 222. A spring 224 is also connected between the side wall of the guide strip 222 facing the second side plate 3 and the cavity wall of the inner cavity 225 facing away from the second side plate 3.

[0028] In addition, please refer to Figure 2 The right end of the second side plate 3 to the erecting station device 14 is Figure 2The distance between the small cigarette pack conveyor platform on the left side of the middle, which is at the starting position, and the distance between the platform and the thickness of the small cigarette pack is greater than the thickness of the small cigarette pack.

[0029] In response, when the push rod mechanism 12 pushes the small cigarette pack on the drying wheel 11 into the small cigarette pack conveying platform in the initial position, and when the small cigarette pack is pushed against the smooth guide surface of the guide shell 223 of the first side plate 2, the spring 224 can be pushed and contracted by the small cigarette pack, and the guide shell 223 moves backward accordingly to prevent the small cigarette pack from being squeezed and deformed.

[0030] Furthermore, when the small cigarette pack is conveyed by the erecting station device 14 to the space between the first side plate 2 and the second side plate 3, the guide shell 223 can maintain an appropriate clamping force on the small cigarette pack under the action of the spring 224, so as to restrict the movement of the small cigarette pack on the conveying platform and prevent the small cigarette pack from tilting and blocking between the first side plate 2 and the second side plate 3 after it moves, which would cause the small cigarette pack to deform or even cause the erecting station device 14 to jam and block.

[0031] It should be noted here that: with Figure 2 Taking the orientation shown as an example, the arc-shaped limiting plate above the vertical station device 14 is used in conjunction with the small cigarette pack conveying platform to limit the small cigarette pack in the vertical direction, preventing the small cigarette pack from tipping to the left. Furthermore, Figure 2 The L-shaped structure at the top of the central erecting station device 14 and facing to the left is the aforementioned small cigarette pack conveying and carrying platform.

[0032] Further, please refer to Figure 4 , Figure 5 , Figure 7In this embodiment, the guide shell 223 includes a shell cover 2231 and a shell body 2232. An inner cavity 225 is formed on the shell body 2232. The inner cavity 225 has a first shell opening 226 and a second shell opening 227 formed on the shell body 2232. The first shell opening 226 faces the shell cover 2231, and the second shell opening 227 faces the first fixing plate 21. A guide strip 222 is inserted into the inner cavity 225 from the second shell opening 227. The body width is the distance from the first housing opening 226 to the inner wall of the housing cavity 225 closest to the guide surface. The cover 2231 is fitted onto the first housing opening 226 of the housing body 2232 by screws or bolts. Technicians can also remove the cover 2231 to install a spring 224 in the housing cavity 225. One end of the spring 224 is fixedly connected to the bottom cavity wall of the housing cavity 225 corresponding to the first housing opening 226, and the other end is fixedly connected to the guide strip 222. Simultaneously, technicians can also fix the cover 2231 to cover the larger first housing opening 226, preventing dust and debris from entering the housing cavity 225, avoiding excessive friction damage to the inner wall of the housing cavity 225 or the surface of the guide strip 222, and preventing the guide shell 223 from being unable to move due to the elastic force of the spring 224 because of particulate matter trapped between the bottom cavity wall of the housing cavity 225 and the guide strip 222.

[0033] Further, please refer to Figure 5 , Figure 6 In this embodiment, one end of the first fixing plate 21 is fixedly installed and the other end is provided with a connecting slope 23. The connecting slope 23 is inclined relative to the second side plate 3. The second guide plate 22 is connected to different positions on the connecting slope 23 so that the second guide plate 22 and the second side plate 3 have different distances.

[0034] Additionally, please see Figure 4 and Figure 6The first fixing plate 21 has two first screw holes 24 on its connecting inclined surface 23. The second guide plate 22 has two strip-shaped through holes 25 at the end corresponding to the connection with the first fixing plate 21. It also includes two first bolts that pass through one strip-shaped through hole 25 and are threaded to one of the first screw holes 24 respectively. The two first bolts cooperate with each other to fix the first fixing plate 21 and the second guide plate 22. The edge of the connecting inclined surface 23 closest to the second side plate 3 is the upper edge of the connecting inclined surface 23. Correspondingly, the first bolts can be threaded to the first screw holes 24 at different positions of the strip-shaped through holes 25 to limit the second guide plate 22 to different positions on the connecting inclined surface 23, so that the relative position of the second guide plate 22 and the first guide plate changes, thereby making the second guide plate 22 and the second side plate 3 have different distances to adapt to the mechanized production needs of small cigarette packs of different types and different lengths.

[0035] Further, please refer to Figure 5 In this embodiment, in order to ensure that the first bolt can better fix the first fixing plate 21 and the second guide plate 22, the first screw hole 24 is set perpendicular to the connecting inclined surface 23.

[0036] Further, please refer to Figure 4 and Figure 5 To prevent the second guide plate 22 from moving downward along the connecting slope 23, which would increase the distance between the first side plate 2 and the second side plate 3 and cause gaps between the small cigarette pack and both side plates when the pack passes between them, thus increasing the risk of the pack getting stuck between the first side plate 2 and the second side plate 3, a third adjusting plate 26 is also provided at the upper end of the connecting end 221 of the second guide plate 22 in a horizontal direction. The third adjusting plate 26 is integrally formed with the first connecting end 221. A second screw hole 27 is vertically opened on the third adjusting plate 26, and a second bolt 28 is provided at the second screw hole 27. The second bolt 28 is threadedly connected to the second screw hole 27, and the lower end of the second bolt 28 also passes through the second screw hole 27 to abut against the upper surface of the second side plate 3.

[0037] In response, after the technicians adjust the position of the second guide plate 22 relative to the first fixed plate 21 according to the length of the cigarette pack and tighten the first bolt, the technicians can also screw on the second bolt 28 to rotate and lower it until the lower end of the second bolt 28 finally abuts against the upper surface of the second side plate 3. This prevents the second guide plate 22 from sliding down the connecting inclined surface 23 due to insufficient friction when the first bolt is loose. This allows the second guide plate 22 to be stably suspended at its current position, improving the quality of the cigarette pack being transported and moved in the vertical tensioning device.

[0038] Anything not mentioned above applies to existing technologies.

[0039] 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.
