[0018] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0019] See Figures 1 to 5 This embodiment discloses an adjustable pressure plate device for a cigarette pack conveying channel of a high-speed packaging machine. The high-speed packaging machine includes a frame 1 and a cigarette pack conveying channel 2 mounted on the frame 1. The conveying direction of the cigarette pack conveying channel 2 is from back to front, and the cigarette pack conveying channel 2 is formed by the gap between two sets of upper and lower conveyor belts 3. A cigarette pack pressure plate 4 is horizontally arranged above the front end of the cigarette pack conveying channel 2. The left and right ends of the cigarette pack pressure plate 4 are respectively connected to the side plates 6 on both sides of the frame 1 through connecting components 5. Each connecting component 5 includes a connector 7 and a flipping block 8. The flipping block 8 is mounted on the mounting shaft 9 of the side plate 6, and the connector 7 is mounted on the flipping block 8. The left and right ends of the cigarette pack pressure plate 4 are respectively provided with vertically extending first oblong holes 10. A first bolt 11 passes through the first oblong holes 10 and is screwed into the first threaded hole 12 of the connector 7. The installation of the cigarette pack pressure plate 4 and the connector 7 is as follows: The connector 7 is provided with an extension plate 13, which is located above the cigarette pack pressure plate 4. The extension screw hole 26 on the extension plate 13 is threaded with a vertically extending adjusting bolt 14. The top left and right ends of the cigarette pack pressure plate 4 are respectively provided with adjusting screw holes 15. The rod of the adjusting bolt 14 is screwed downward into the adjusting screw hole 15 on the corresponding side of the top of the cigarette pack pressure plate 4. The upper section of the adjusting bolt 14 is threaded with a locking nut 16, which is located on the upper side of the extension plate 13.

[0020] The connector 7 is a T-shaped plate formed by a horizontal plate and a vertical plate. The extension plate 13 and the mounting plate are located on the front and rear sides of the vertical plate, respectively, and together they form the horizontal plate. The mounting plate has a second oblong hole 17 extending front and rear. A second bolt 18 passes through the second oblong hole 17 of the mounting plate and is screwed into the second threaded hole of the flip block 8 to achieve the connection between the connector 7 and the flip block 8. The first threaded hole 12 is opened on the vertical plate of the connector 7. The rear side of the cigarette pack pressure plate 4 has a vertical guide groove 19 corresponding to the vertical plate of the connector 7. The vertical guide groove 19 of the cigarette pack pressure plate 4 is vertically slidingly engaged with the vertical plate.

[0021] The flipping block 8 is rotatably mounted on the mounting shaft 9 of the side plate 6. A cigarette pack pressure plate limiting rod 20 is fixed to one side of the cigarette pack pressure plate 4. The rear end of the cigarette pack pressure plate limiting rod 20 is connected to the lower end of the tension spring 21. The upper end of the tension spring 21 is fixed to the side plate 6. The tension spring 21 is arranged at an angle. A limiting block 22 is fixed on the side plate 6. A vertically extending limiting screw 23 is threaded onto the limiting block 22. The bottom end of the limiting screw 23 abuts against the top end of the cigarette pack pressure plate limiting rod 20. The tension spring 21 applies an upward elastic force to the rear end of the cigarette pack pressure plate limiting rod 20. At the same time, the bottom end of the limiting screw 23 abuts against the top end of the cigarette pack pressure plate limiting rod 20, thereby limiting the position of the cigarette pack pressure plate limiting rod 20 and preventing it from moving upward. This prevents the cigarette pack pressure plate 4 from moving upward during operation and failing to support the cigarette pack 25. The cigarette pack pressure plate 4 has an upwardly extending handle 24 on its rear side.

[0022] During operation, cigarette packs 25 are conveyed from back to front through a cigarette pack conveying channel 2 formed by two sets of conveyor belts 3. When they pass the cigarette pack pressure plate 4, the pressure plate 4 presses down on the top surface of the cigarette pack 25, causing it to pause at that position. The following cigarette packs 25 continue to be conveyed forward until they come into contact with the preceding cigarette packs 25. When a certain number of cigarette packs 25 are stacked, the thrust of the conveyor belt 3 on the top and bottom surfaces of the stacked cigarette packs 25 increases to a level sufficient to overcome the frictional force of the pressure plate 4 on the top surface of the first cigarette pack 25. This pushes the stacked group of cigarette packs 25 forward into the drying drum of the downstream machine. When the thrust of the stacked cigarette packs 25 is less than the frictional force of the pressure plate 4 on the top surface of the first cigarette pack 25, a reciprocating cycle of stacking and conveying cigarette packs 25 is formed.

[0023] When it is necessary to adjust the front and back position of the cigarette pack pressure plate 4, first loosen the second bolt 18, adjust the front and back position of the connector 7 to the appropriate position, and then tighten the second bolt 18 to achieve fine adjustment of the front and back position of the cigarette pack pressure plate 4.

[0024] During production, cigarette pack 25 is in a sideways position in the cigarette pack conveying channel 2. When the label paper is changed to that of different manufacturers or brands, the friction between the cigarette pack pressure plate 4 and the top surface of the cigarette pack 25 will change slightly, causing the cigarette pack 25 to tilt and the cigarette pack conveying channel 2 to become blocked. This problem can be solved by adjusting the height of the cigarette pack pressure plate 4. The specific adjustment process is as follows:

[0025] First, loosen the first bolt 11 on the cigarette pack pressure plate 4, and then rotate the locking nut 16 on the adjusting bolt 14 so that the locking nut 16 moves upward away from the extension plate 13. Then, rotate the adjusting bolt 14 with a wrench. Under the threaded engagement of the adjusting bolt 14 and the adjusting screw hole 15 on the top of the cigarette pack pressure plate 4, the cigarette pack pressure plate 4 can be moved vertically, thereby adjusting the vertical position of the cigarette pack pressure plate 4. When the height of the cigarette pack pressure plate 4 is adjusted to the appropriate position, tighten the first bolt 11 and the locking nut 16 in sequence to lock the height position of the cigarette pack pressure plate 4. In this way, the convenient and quantitative adjustment of the height position of the cigarette pack pressure plate 4 is completed.

[0026] If the cigarette pack 25 is tilted or deformed during the production process, causing the cigarette pack conveying channel 2 to be blocked at the cigarette pack pressure plate 4, the cigarette pack pressure plate 4 can be flipped and lifted backward and upward around the mounting shaft 9 of the flipping block 8 by the handle 24, with a rotation degree range of 0-45 degrees, so as to remove the problematic cigarette pack 25 from the cigarette pack conveying channel 2 and prevent the problematic cigarette pack 25 from flowing into the downstream drying drum.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
