Technical Field

[0001] The utility model relates to the technical field of vacuum overflow prevention filling, in particular to a liquid vacuum overflow prevention filling device. Background Art

[0002] The vacuum filling machine is a machine that fills the bottle under a pressure lower than the atmospheric pressure. It uses continuous vacuum suction to draw the product into the container. The continuous suction is generated by a vacuum pump connected to a vacuum chamber and a special filling valve. When the liquid is filled, when the filling of two bottles is switched, the liquid will overflow even if the inlet valve is closed, and drip directly from the filling head, resulting in some liquid always remaining at the outlet of the filling head. The existing filling head does not have the function of instantaneous closing to block the liquid, so we propose a liquid vacuum overflow prevention filling equipment. Utility Model Content

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Embodiment 1

[0018] See attached Figure 1-4 A liquid vacuum overflow prevention filling device comprises a filling machine body 1 and a liquid container 2. A filling tube 3 is installed at the bottom of the liquid container 2 through an infusion tube 7. A filling head device 4 is installed at the bottom of the filling tube 3. The filling head device 4 is composed of a plurality of arc blocks 41. The plurality of arc blocks 41 form a cone shape. An elastic sealing belt 46 is connected between adjacent arc blocks 41. A mounting plate 43 is installed on the arc blocks 41. The filling head device 4 also includes a mounting cavity 44 opened in the wall of the filling tube 3. Both sides of the mounting plate 43 are installed in the mounting cavity 44 through a mounting structure 8. The mounting structure 8 includes a hinged mounting plate 46 on the mounting cavity 44. The mounting seat barrel 81 on the inner wall of the cavity 44 has a support column 82 slidably installed in the mounting seat barrel 81, a spring 84 is installed between the support column 82 and the mounting seat barrel 81, and a hinge joint 83 is hinged between the support column 82 and the mounting plate 43. When the mounting plate 43 is moved by force, it pushes the support column 82 there in the force direction, so that the spring 84 contracts, and when the force disappears, the spring 84 automatically rebounds to reset the mounting plate 43. The mounting seat barrel 81 is hinged on the inner wall of the mounting cavity 44, and the mounting plate 43 and the support column 82 are hingedly arranged with the hinge joint 83, so that the mounting plate 43 can be moved. 3 can be changed in direction, which is more flexible. An arc-shaped side block 42 is installed on the arc-shaped block 41, and a mounting plate 43 is installed on the arc-shaped side block 42. An arc-shaped side groove 45 adapted to the arc-shaped side block 42 is opened below the mounting cavity 44. The arc-shaped side block 42 is located in the arc-shaped side groove 45. In this way, when the arc-shaped block 41 is pushed away by the impact force of the liquid, the arc-shaped side block 42 will move in a similar rotational manner in the arc-shaped side groove 45. Because the two are adapted, it is ensured that the liquid will not flow out from there, and it is ensured that the mounting plate 43 can move normally in the mounting cavity 44. By installing a filling head device at the bottom of the filling tube 3 4 is set, and the filling head device 4 can ensure that the liquid will not overflow. When the liquid flows out of the filling tube 3, the liquid enters the filling head device 4, and the discharge of the liquid brings an impact force, so that the multiple arc blocks 41 are opened to form a liquid outlet. At this time, the elastic sealing belt 46 will be stretched, and the elastic sealing belt 46 can prevent the liquid from being discharged from the gap between adjacent arc blocks 41. When the impact force brought by the liquid disappears, the multiple arc blocks 41 will automatically close, thereby realizing automatic opening and closing, and based on the flow rate of the liquid, it is ensured that the liquid will not overflow while filling.

[0019] The working principle of a liquid vacuum overflow prevention filling device based on the first embodiment is: after the liquid is input into the filling tube 3 from the infusion tube 7, the liquid is discharged through the liquid outlet head 32. When the liquid flows into the filling head device 4, the impact force of the liquid causes the multiple arc blocks 41 to separate. At this time, the elastic sealing belt 46 is stretched, and the arc block 41 will drive the mounting plate 43 to move, which will push the support column 82 there in the force direction, thereby causing the spring 84 to contract. When the force disappears, the spring 84 will automatically rebound to reset the mounting plate 43. At this time, the arc side block 42 will move in a similar rotational manner in the arc side groove 45. Because the two are adapted, this ensures that the liquid will not flow out from there, and ensures that the mounting plate 43 can move normally in the mounting cavity 44, thereby forming a liquid outlet between the arc blocks 41, and the liquid will flow into the filling bottle.

A reflux cavity 35 is formed between the convex backflow prevention panel 33 and the inner wall of the filling tube 3. This arrangement can prevent the problem of liquid backflow, and the reflux cavity 35 can be used to store overflowed liquid. The infusion tube 7 is connected to a direct current tube 34, and the direct current tube 34 Located in the filling chamber 31, the direct current pipe 34 is arranged opposite to the anti-backflow convex enclosure 33, the filling pipe 3 is also provided with a discharge nozzle 36, and the filling machine body 1 also includes a base 5, on which a conveyor belt 6 is opened, and wiping limit columns 9 are rotatably installed on both sides of the base 5. The surface of the wiping limit column 9 is provided with bristles 10. When the filling bottle is located on the conveyor belt 6 and moves, if liquid overflows, it will flow to the bottom of the filling bottle, so that it can be wiped by the bristles 10, thereby avoiding contamination of the conveyor belt.
