In addition, the existing pneumatic shaft cannot be installed with pneumatic slip rings, which cannot meet the use requirements of the cigarette tipping paper tray packaging machine.

[0018] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0019] See also Figure 1-2As shown, the utility model is an air expansion shaft of a cigarette tipping paper tray wrapping machine, comprising a connecting shaft 1 for installing a pneumatic slip ring, an air expansion cylinder 2 for tightening the paper tray is provided at one end of the connecting shaft 1, a sealing cover 3 is provided at one end of the open end of the air expansion cylinder 2, an expansion air bag 4 is provided on the sealing cover 3, the expansion air bag 4 is inserted in the air expansion cylinder 2, an air inlet channel 5 connected to the inner cavity of the air expansion cylinder 2 is opened in the connecting shaft 1, a plurality of movable arc plates 6 are provided between the air expansion cylinder 2 and the expansion air bag 4, a tensioning plate 8 is provided on the movable arc plate 6, a plurality of grooves 13 of the same length as the tensioning plate 8 are axially provided on the outer circle of the air expansion cylinder 2, the tensioning plate 8 is slidably inserted in the groove 13, and a plurality of friction strips 7 for increasing the friction coefficient are provided on the outer surface of the tensioning plate 8, by providing the connecting shaft 1, the pneumatic slip ring can be installed on the connecting shaft 1 when in use, and an installation position is effectively provided, so that the air expansion shaft can meet the needs of cigarette tipping paper tray wrapping. The air expansion shaft is rotatably installed on the tray wrapping machine through the connecting shaft 1. When the paper tray needs to be tightened, ventilation is carried out through the air inlet channel 5, and the gas inflates the expansion airbag 4, causing the expansion airbag 4 to expand, thereby pushing the movable arc plate 6 to move outward with the tensioning plate 8. When multiple tensioning plates 8 are opened, the paper tray can be firmly tightened. When the air expansion shaft is rotated, the paper tray can be driven to rotate, so that the winding and unwinding work can be completed smoothly. By adding friction strips 7, the friction coefficient between the tensioning plate 8 and the paper tray is increased. The friction force between the two is greater during rotation. In the process of winding, it is not easy to slip or move left and right, which improves the winding efficiency. A positioning groove 13 is reserved between the friction strips 7, so that the paper tray can be quickly positioned through the positioning groove 13, which has the effect of rapid installation and avoids the problem of offset.

[0020] Specifically, the friction strips 7 are arranged in a rectangular array, which can better fit the inner hole of the paper plate. The friction strips 7 are made of rubber material to increase friction and effectively prevent the occurrence of slipping.

[0021] Preferably, the friction strip 7 and the tensioning plate 8 are of an integrated structure, which is convenient for production and manufacture and prevents the friction strip 7 from falling off during use.

[0022] Furthermore, a plug-in tube 12 is provided at one end of the expansion airbag 4, and the plug-in tube 12 is plugged into the air inlet channel 5, so that after the gas enters from the air inlet channel 5, it can better enter the expansion airbag 4 through the plug-in tube 12, so that the expansion airbag 4 can expand quickly, thereby realizing the rapid tightening of the paper plate by the air inflation shaft.

[0023] Furthermore, a plurality of mounting grooves are provided on the outer circumference of the plug-in tube 12, and a sealing ring 11 is provided on the mounting groove to improve the sealing performance and effectively prevent air leakage at the connection.

[0024] Furthermore, spring pieces 9 with elastic function are provided on the movable arc plates 6 on both sides of the tensioning plate 8. When the air supply is disconnected, the movable arc plates 6 can be quickly reset under the elastic force of the spring pieces 9, thereby releasing the tensioned paper tray.

[0025] Furthermore, the sealing cover 3 is detachably connected to the inflation tube 2 via the locking screw 10, so as to facilitate the installation and disassembly of the entire device and the replacement of the inflation airbag 4 at a later time.

[0026] Furthermore, positioning grooves 14 are reserved between the friction strips 7, and the paper tray can be quickly positioned through the positioning grooves 14, achieving a quick installation effect while avoiding the problem of offset.

[0027] When the pneumatic shaft of a cigarette tipping paper tray wrapping machine of the present embodiment is in use, a connecting shaft 1 is provided, and a pneumatic slip ring can be installed on the connecting shaft 1 when in use, which effectively provides an installation position, so that the pneumatic shaft can meet the use requirements of the cigarette tipping paper tray wrapping machine. The pneumatic shaft is rotatably installed on the tray wrapping machine through the connecting shaft 1. When the paper tray needs to be tightened, ventilation is carried out through the air inlet channel 5, and the gas inflates the expansion airbag 4, so that the expansion airbag 4 expands, thereby pushing the movable arc plate 6 to move outward with the tensioning plate 8. When multiple tensioning plates 8 are tightened, the expansion airbag 4 is inflated by the air inlet channel 5. After all are opened, the paper tray can be firmly tightened. When the air expansion shaft is rotated, the paper tray can be driven to rotate, so that the winding and unwinding work can be completed smoothly. By adding friction strips 7, the friction coefficient between the tensioning plate 8 and the paper tray is increased. The friction between the two is greater during rotation, and it is not easy to slip or shift left and right during the winding process, which improves the efficiency of winding. Positioning grooves 14 are reserved between the friction strips 7, so that the paper tray can be quickly positioned through the positioning grooves 14, which has the effect of rapid installation and avoids the problem of offset. The utility model is a kind of air expansion shaft of the cigarette tipping paper tray packaging machine, which can achieve rapid positioning of the paper tray while ensuring the tightening effect, effectively improves the work efficiency, and has the characteristics of easy use and strong practicality.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
