The bottom of the ball groove 4 is sealed, and the side of the ball groove 4 is provided with four evenly distributed slots 5. The inside of ball groove 4 is provided with the sealing ball 10 that diameter is 7mm. A guide ring 2 is arranged between the air return pipe and the ball groove 4, and the guide ring 2 is a cone surface, and the bottom end of the cone surface of the guide ring 2 is arranged at an end close to the ball groove 4; the guide ring 2 The diameter of the bottom end of the cone is 11mm. The top end of the inner tube of the ball groove 4 is a conical surface i...

Embodiment 2

[0024] Different from Embodiment 1, the inner diameter of the air return pipe is 5 mm, the diameter of the sealing ball 10 is 8 mm, and the inner diameter of the ball groove 4 is 8.5 mm. The side of the ball groove 4 is provided with two evenly distributed groove holes 5 . The diameter of the top end of the tapered inner tube 7 is 5 mm, and the diameter of the bottom end of the tapered inner tube 7 is 8.5 mm. The included angle between the conical generatrices of the conical inner tube 7 and the bottom surface is 35°. The length of the ball groove 4 is 15mm, and the length of the air return pipe is 100mm. The length of the slot 5 is 10 mm, and the width of the slot 5 is 4 mm.

[0025] The air return pipe includes an upper air return pipe 1 and a lower air return pipe 8, a groove 11 is provided between the upper air return pipe 1 and the lower air return pipe 8, and a detachable scattering ring 9 is provided outside the groove 11. The scatter ring 9 is arranged on the top of...

Embodiment 3

[0027] The difference from embodiment 2 is that the inner diameter of the air return pipe is 4.5 mm, the diameter of the sealing ball 10 is 7.5 mm, and the inner diameter of the ball groove 4 is 8.0 mm. The side of the ball groove 4 is provided with three evenly distributed groove holes 5 . The diameter of the top end of the tapered inner tube 7 is 4.5 mm, and the diameter of the bottom end of the tapered inner tube 7 is 8.0 mm. The included angle between the conical generatrices of the conical inner tube 7 and the bottom surface is 55°. The length of the ball groove is 10mm, and the length of the air return pipe is 130mm. The length of the slot 5 is 8 mm, and the width of the slot 5 is 3.5 mm. The diameter of the bottom end of the conical surface of the scattering ring 9 is 8.5mm. The scattering ring is made of rubber, and the sealing ball is a PPSU (polyphenylsulfone) hollow ball with a wall thickness of 1.8mm.

Abstract

The invention provides a pellet-type air return pipe device for a filling machine. The pellet-type air return pipe device comprises an air return pipe. A pellet groove is formed in the lower portion of the air return pipe, and the bottom end of the air return pipe is connected with the top end of the pellet groove. The pellet groove is a hollow pipe with the internal diameter being D. The bottom end of the pellet groove is sealed, a groove hole is formed in the side face of the pellet groove, and a sealing pellet is arranged inside the pellet groove. The diameter of the sealing pellet is R, wherein R is larger than d and smaller than 2d, and D is larger than R and smaller than R+0.5 mm. the density of liquor is rho, and the density of the sealing pellet is rho, wherein rho is larger than 0.3rho and smaller than 0.7rho. The pellet groove is formed in the bottom of the air return pipe, the sealing pellet which can flexibly move is arranged in the pellet groove, due to the fact that the diameter of the sealing pellet is larger than the internal diameter of the air return pipe, the sealing pellet seals the bottom end of the air return pipe under the effect of buoyancy of beer liquid, and therefore the beer liquid is prevented from entering the air return pipe. Beer losses caused by blowout of the beer liquid in the air return pipe are reduced from 1.13% in the prior art to 0.22%, about 5.5ml beer liquid can be saved for each bottle of beer, and great economic benefits are generated.

Description

technical field [0001] The invention belongs to the field of filling machine spare parts, in particular to a return air pipe device for canning beer, in particular to a small ball return air pipe device for a filling machine. Background technique [0002] The filling machine is the focus of the entire beer filling line. The bottle filling machine generally adopts a rotary structure. The bottles are sent into the machine by the conveyor belt, and the bottle flow is separated by a certain distance through the bottle separating device-bottle feeding screw, and the bottle is transferred to the movable bottle tray through the input star wheel. , and finally realize the positioning of the bottle under the filling mechanism. [0003] The filling process usually includes the following steps: (1) Vacuuming: the bottle and the centering cover are tightly crimped on the filling valve, and the vacuum valve is opened by a fixed stopper. In a short time, the vacuum in the bottle The deg...
