[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-5As shown in the figure, the yogurt filling head back suction structure provided by this utility model embodiment includes a workbench 1. A bidirectional screw 2 is rotatably fitted at one edge of the workbench 1. Both ends of the bidirectional screw 2 are threaded with a frame 3. Multiple small rollers 4 are rotatably fitted inside the two frames 3. A conveyor belt 5 is installed between the peripheries of the multiple small rollers 4. The two conveyor belts 5 correspond to each other. A connecting frame 6 is installed on the upper side of the workbench 1. A horizontal plate 7 is slidably fitted inside the connecting frame 6. Multiple filling tubes 8 corresponding to the two conveyor belts 5 are installed in the middle of the horizontal plate 7. Blocks 9 are slidably fitted inside the multiple filling tubes 8. Through holes 10 are opened in the middle of the multiple blockes 9. A pressing component corresponding to the multiple blockes 9 is installed on the upper side of the horizontal plate 7. Multiple return tanks 11 and material buckets 12 are installed at both ends of the workbench 1, and the through holes 10 are connected to the return tanks 11.

[0027] In this embodiment, a workbench 1 is included, and a bidirectional screw 2 is rotatably fitted on one side edge of the workbench 1.

[0028] Specifically, a rod 13 is rotatably fitted at one end of the workbench 1. Both the rod 13 and the adjacent ends of the bidirectional screw 2 are equipped with bevel gears 14. The two bevel gears 14 mesh with each other. A first motor 15 is installed on the lower side of the workbench 1, and the output end of the first motor 15 is fixed to one end of the rod 13. The first motor 15 can drive the rod 13 to rotate, so that the rod 13 drives one of its bevel gears 14 to rotate synchronously. Thus, the two bevel gears 14 mesh and rotate, thereby driving the bidirectional screw 2 and effectively improving the overall linkage.

[0029] Specifically, valves are provided at multiple discharge ports, and a collection box 28 is installed on the lower side of one end of the workbench 1. A transmission pipe connected to the collection box 28 is installed at one end of each of the multiple valves, and two frames 3 are slidably fitted on the upper side of the workbench 1. Through the collection box 28, the yogurt in multiple return tanks 11 can be collected and stored.

[0030] In this embodiment, both ends of the bidirectional screw 2 are threaded with a frame 3, and multiple small rollers 4 are rotatably fitted on the inner side of the two frames 3. A conveyor belt 5 is installed between the periphery of the multiple small rollers 4, and the two conveyor belts 5 correspond to each other.

[0031] Specifically, a second motor 16 is installed on the upper side of each of the two frames 3. The output ends of the two second motors 16 are fixed to the shaft center of the two small rollers 4. A first support rod 17 is installed on the edge of the other side of the workbench 1, and the two frames 3 slide in cooperation with the periphery of the first support rod 17. By setting the first support rod 17, the two frames 3 slide in cooperation with the periphery of the first support rod 17, thereby further improving the stability when clamping the bottle.

[0032] In this embodiment, a connecting frame 6 is installed on the upper side of the workbench 1, and a horizontal plate 7 is slidably fitted on the inner side of the connecting frame 6. A plurality of filling tubes 8 corresponding to the two conveyor belts 5 are installed in the middle of the horizontal plate 7. A block 9 is slidably fitted inside each of the plurality of filling tubes 8, and a through hole 10 is opened in the middle of each of the plurality of block 9.

[0033] Specifically, the inner sides of the three diagonal corners of the connecting frame 6 are each equipped with a second support rod 18. The inner side of the connecting frame 6 is rotatably fitted with a screw 19. The periphery of the screw 19 is threadedly fitted with one end of the horizontal plate 7. The horizontal plate 7 is slidably fitted with the periphery of the three second support rods 18. The upper side of the connecting frame 6 is equipped with a third motor 20. Through the screw 19, the screw 19 is threadedly fitted with the horizontal plate 7, so that the horizontal plate 7 drives multiple filling tubes 8 to move up and down synchronously, in preparation for the next step of filling yogurt or sucking back the yogurt in the bottle.

[0034] Specifically, the output end of the third motor 20 is fixed to one end of the screw 19, and grooves 21 corresponding to the block 9 are opened on the periphery of the multiple filling tubes 8. The upper end of the material barrel 12 is equipped with connecting pipes 22 corresponding to the multiple grooves 21, and one end of the connecting pipe 22 is equipped with an air pump. Through the air pump, the yogurt in the material barrel 12 can be introduced into the filling tubes 8 through the grooves 21 to prepare for the next step of filling the yogurt.

[0035] Specifically, the upper end of the connecting frame 6 is equipped with a vacuum pump 26 connected to multiple filling pipes 8, and multiple through holes 10 are connected to multiple return tanks 11 by return pipes 27. Each of the multiple return tanks 11 has a discharge port on its lower side. Through the vacuum pump 26, a negative pressure is formed in the multiple return tanks 11, so that the yogurt in the bottle is drawn back into the multiple return tanks 11 under the action of atmospheric pressure, thus realizing the yogurt reabsorption.

[0036] In this embodiment, the upper side of the horizontal plate 7 is equipped with a pressing component corresponding to multiple blocking blocks 9, and multiple return tanks 11 and material buckets 12 are installed at both ends of the workbench 1, and the through hole 10 is connected to the return tank 11.

[0037] Specifically, the pressing assembly includes an inverted U-shaped frame 23 mounted on the upper side of the horizontal plate 7, a cylinder 24 mounted on the upper side of the inverted U-shaped frame 23, and a pressing plate 25 mounted on the output end of the cylinder 24. The lower side of the pressing plate 25 is equipped with columns corresponding to multiple blocking blocks 9. The pressing plate 25 is slidably fitted to the inner side of the inverted U-shaped frame 23. Through the cylinder 24, the pressing plate 25 can be driven to move downward, so that the pressing plate 25 drives multiple blocking blocks 9 to move downward synchronously, thereby closing multiple grooves 21 synchronously, preparing for the next step of sucking back the yogurt in the bottle.

[0038] Working steps: 1. When it is necessary to clamp the bottles, first place multiple bottles on the upper side of the workbench 1. After placement, start the first motor 15. The output end of the first motor 15 drives the rod 13 to rotate, so that the rod 13 drives its bevel gear 14 to rotate synchronously. Thus, the two bevel gears 14 mesh and rotate, driving the bidirectional screw 2 to rotate synchronously, so that the bidirectional screw 2 is threadedly engaged with the two frames 3, so that the two frames 3 move closer to each other. At this time, the two frames 3 slide on the periphery of the first support rod 17, and at the same time, the two conveyor belts 5 contact the periphery of multiple bottles to achieve clamping and fixing of bottles of different sizes.

[0039] 2. When yogurt needs to be filled, start the third motor 20. The output end of the third motor 20 drives the screw 19 to rotate, so that the screw 19 is threadedly engaged with the horizontal plate 7, thereby driving the horizontal plate 7 to move downward. At this time, the horizontal plate 7 is slidably engaged with the three second support rods 18 around its periphery. At the same time, the horizontal plate 7 drives multiple filling tubes 8 to move downward synchronously and inserts the lower ends of multiple filling tubes 8 into the bottle. Then start the cylinder 24. The output end of the cylinder 24 drives the pressing plate 25 to move upward, so that the pressing plate 25 drives multiple columns to move upward synchronously. Thus, multiple columns drive multiple plugs 9 to slide in the interior of multiple filling tubes 8, which can open multiple grooves 21 synchronously. At this time, start the air pump. The air pump can introduce the yogurt in the material tank 12 into the interior of multiple filling tubes 8 through the connecting pipe 22. At the same time, the yogurt falls along the inner wall of multiple filling tubes 8 into multiple bottles, thereby realizing the filling of yogurt.

[0040] 3. When it is necessary to back-suction the yogurt, start the cylinder 24. The output end of the cylinder 24 drives the pressing plate 25 to move downward. At this time, the pressing plate 25 drives multiple blocking blocks 9 to move downward simultaneously, which can close multiple grooves 21 simultaneously. Then, start the vacuum pump 26 to create negative pressure in multiple return tanks 11. As a result, the yogurt in the bottle is back-suctioned into multiple return tanks 11 under the action of atmospheric pressure along multiple through holes 10, realizing the back-suction of yogurt. When the yogurt in multiple return tanks 11 is full, open multiple valves. At this time, multiple return tanks 11 are introduced into the collection box 28 through multiple transmission pipes for collection and storage.

[0041] 4. When it is necessary to transfer the yogurt after filling or re-suction, two second motors 16 are started at the same time. The output ends of the two second motors 16 drive the two small rollers 4 to rotate, so that the two small rollers 4 drive the two conveyor belts 5 to rotate synchronously. Thus, the two conveyor belts 5 move the yogurt after filling or re-suction, realizing the transfer of the yogurt after filling or re-suction.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
