A roller seat 50 is provided on the telescopic part of the cylinder 40. The roller seat 50 is provided with a roller 51 , and guide rods 60 are respectively provided on both sides of the roller seat 50 . The end is connected with the bottle clamping plate 20, the dummy cup 10 is located under the valve port of the filling valve 30, and the axis line of the cylinder 40, the axis line of the filling valve 30 and the longitudinal center line of the roller 51 coincide. The cylinder 40 includes a cylinder seat 41 and a piston rod 42 arranged in the cylinder seat 41 . The bottle lifting device of the filling machine also includes a connecting seat 70 . The filling valve 30 is connected to the lower part of the connecting seat 70 . Surface connection, the cylinder seat 41 is connected with the upper surface of the connecting seat 70, the cylinder seat 41 in this embodiment is fixed, the piston rod 42 can move in the cylinder seat 41, and the piston rod 42 is the cylinder 40 According to the actual requirements, the piston rod 42 can also be fixed, so that the cylinder seat 41 moves along the piston rod 42, in this connection mode, the cylinder seat 41 is a telescopic part of the cylinder.
[0024] The bottle lifting device of the filling machine connects the roller 51, the dummy cup 10, the bottle clamping plate 20, the filling valve 30 and the cylinder 40 into an integral structure, which is better than the traditional structure in terms of processing cost and maintenance cost. The cost is low and the structure is simple. The cylinder 40 is connected to the bottle clamping plate 20 through the guide rod 60 to lift the bottle to the valve port of the filling valve 30. There is no suspended force arm in the middle, and the bottle clamping plate 20 is not easily deformed, and the bottle mouth can be filled during filling. It is effectively sealed and air-tight. The bottle lifting device of the filling machine drives the bottle up and down through the guide rod 60. The axis line of the cylinder 40 coincides with the axis line of the filling valve 30, which avoids the time between the components when the traditional lifting structure drives the bottle up and down. The unilateral force wear of the guide ring brought by the suspended force arm makes the seal evenly stressed and not easy to wear, prolonging the service life of the seal, and the axis line of the cylinder 40, the axis line of the filling valve 30 and the longitudinal direction of the roller 51 The center lines are coincident. When the bottle is being filled, under the action of compressed air, the telescopic part of the cylinder 40 moves upward, and the roller seat 50 is connected with the guide rod 60 to drive the bottle clamping plate 20 to move upward to lift the bottle, so that the bottle mouth rests on the valve. Filling at the mouth; when the filling is completed, the roller 51 moves downward under the action of the guide rail of the filling machine, and the guide rod 60 drives the bottle clamping plate 20 to move downward under the action of force, so that the bottle leaves the valve mouth and enters the star wheel, and continues The filling of the next bottle, such a cycle, whether it is lifting or lowering, the force is concentrated in the axis direction of the filling valve 30, which can effectively control the stability of the bottle lifting. The carbon dioxide in the carbonated beverage is not easy to overflow and generate foam due to shaking, which improves the filling efficiency and filling accuracy.
[0025] like figure 1 , 3 As shown, the upper end of the cylinder seat 41 is provided with a flange 411, both sides of the flange 411 are provided with first guide holes 412, the lower end of the filling valve 30 is sleeved with a guide member 310, the Both sides of the guide member 310 are provided with second guide holes 311 , and the guide rod 60 is connected to the dummy cup 10 after passing through the first guide hole 412 and the second guide hole 311 in sequence. The first guide hole 412 and the second guide hole 311 can further guide the lifting and lowering of the guide rod 60, so that the guide rod 60 can move smoothly in the direction of the axis of the filling valve 30, so as to avoid the distortion of the bottle jam plate 20 caused by the twist. The bottle cannot be aligned with the opening of the filling valve 30.
[0026] like figure 1 , 2 As shown, the connecting seat 70 is provided with a ventilation mechanism 80 , and one end of the cylinder block 41 close to the connecting seat 70 is provided with a ventilation hole, and the ventilation hole communicates with the ventilation mechanism 80 . The ventilation mechanism 80 feeds compressed air into the cylinder base 41, so that the piston rod 42 moves up along the axis of the cylinder base 41, thereby driving the roller base 50, the guide rod 60, the dummy cup 10 and the bottle clamping plate 20 to rise together, and the bottle is stuck. The cylinder 40 is installed above the filling valve 30, and the two are integrated together, which not only reduces the assembly error transmitted between the components, but also ensures that the lifting force is along the axis of the filling valve 30. direction to further improve the filling accuracy.
[0027] like figure 1 , 3 As shown, the piston rod 42 in this embodiment is connected to the middle of the roller seat 50 , two guide rods 60 are located on both sides of the piston rod 42 , and the two guide rods 60 are symmetrically arranged relative to the piston rod 42 . In this way, the force balance of the piston rod 42 can be ensured, so that both the lifting and lowering processes can be kept stable.
[0028] like Figures 1 to 3 As shown, the roller seat 50 has a U-shaped structure, and its bottom surface is connected with the piston rod 42 and the two guide rods 60, and its two sides are respectively provided with mounting holes, and the mounting holes are provided with a rotating shaft 510, and the rollers 51 is mounted on the rotating shaft 510 . After the filling is completed, the roller 51 moves downward under the action of the guide rail of the filling machine. Since the roller 51 is located above the cylinder 40, the roller 51 is directly transmitted to the roller seat 50 by the downward force, and the transmission is stable, and then transmitted to the piston rod 42. and the guide rod 60, thereby driving the bottle card board 20 to descend.
