Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to a leak-proof filling mechanism for a filling machine. Background Technology

[0002] Filling machines are widely used in various industries such as food, pharmaceuticals, daily chemicals, and oils, and can fill different high-viscosity fluids.

[0003] In existing filling machines, the filling tube is inserted into the container of the liquid to be filled for filling. When the container reaches the standard filling level, the liquid delivery stops. However, after the filling tube rises and detaches from the container, liquid easily drips from its outer wall. This dripping not only causes material loss but also contaminates the container's outer wall. Furthermore, during filling, the significant impact force can cause some liquid to leak directly from the gap between the filling tube and the inner wall of the container opening, resulting in further loss and contamination. To avoid these issues, a leak-proof filling mechanism needs to be designed for the filling machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a leak-proof filling mechanism for filling machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A leak-proof filling mechanism for a filling machine includes a base plate and a filling tube. The upper surface of the base plate has multiple clamping grooves and a moving groove. The base plate has a transmission cavity inside, and a drive motor is installed within the transmission cavity. Adjusting screws extending into the transmission cavity are rotatably installed in each of the clamping grooves. The adjusting screws are connected to the drive motor via a transmission mechanism. An adjusting plate is threadedly fitted onto the outer wall of the adjusting screw via a first limiting mechanism. A clamping plate is installed on the adjusting plate. A moving screw is rotatably installed in the moving groove. A moving nut is threaded onto the outer wall of the moving screw via a second limiting mechanism. A moving plate is installed on the moving nut via an insertion mechanism. A lifting frame is installed on the moving plate via a first cylinder. A leak-proof plate is installed below the lifting frame via a connecting rod. Both the lifting frame and the leak-proof plate have openings corresponding to the filling tube. The filling tube is connected to the lifting frame via a connecting frame and a second cylinder. Dragging grooves are provided on both outer walls of the moving plate. Anti-detachment rods are installed in the dragging grooves via an elastic mechanism. Anti-detachment grooves are also provided on both outer walls of the base plate.

[0007] Preferably, the transmission mechanism includes a drive gear disposed on the output shaft of the drive motor, and the end of the adjusting screw is provided with a transmission gear that meshes with the drive gear.

[0008] Preferably, the first limiting mechanism includes a first limiting rod disposed in the clamping groove, the first limiting rod sliding through the adjusting plate.

[0009] Preferably, the second limiting mechanism includes a second limiting rod disposed in the moving groove, the second limiting rod slidingly penetrating the moving nut.

[0010] Preferably, the insertion mechanism includes a rod disposed on the movable nut, and the bottom wall of the movable plate is provided with a slot corresponding to the rod.

[0011] Preferably, the elastic mechanism includes a spring disposed in the drag groove, with both ends of the spring being elastically connected to the outer wall of the anti-detachment rod and the inner wall of the drag groove, respectively.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as a leak-proof plate, a first cylinder, a second cylinder, and a moving screw, this device can scrape off any misaligned objects from the filling tube when it is finished filling and rises to detach from the bottle, thus preventing dripping after the filling tube rises. Furthermore, during filling, the leak-proof plate contacts and presses down on the bottle to prevent objects from leaking out from the gap between the filling tube and the bottle opening.

[0014] 2. By setting up components such as movable nuts, insert rods, and anti-detachment rods, the device is relatively large overall. However, the movable plate, which facilitates the easy assembly and disassembly of the movable screws, allows for the flexible disassembly of multiple components. After disassembly, the device is broken down into multiple parts, making it convenient for storage, organization, and transportation, thus ensuring the ease of use of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A leak-proof filling mechanism for a filling machine includes a base plate 1 and a filling tube 11. The upper surface of the base plate 1 is provided with multiple clamping grooves 2 and a moving groove 5. The base plate 1 has a transmission cavity inside, and a drive motor 20 is provided in the transmission cavity. Adjusting screws 23 extending into the transmission cavity are rotatably provided in each of the multiple clamping grooves 2. The adjusting screws 23 are connected to the drive motor 20 through a transmission mechanism. An adjusting plate 3 is threadedly fitted on the outer wall of the adjusting screw 23 through a first limiting mechanism. A clamping plate 4 is installed on the adjusting plate 3. A moving screw 16 is rotatably provided in the moving groove 5. A moving nut 17 is threadedly fitted on the outer wall of the moving screw 16 through a second limiting mechanism. A moving plate 6 is provided on the moving nut 17 through an insertion mechanism. A lifting frame 8 is provided on the moving plate 6 through a first cylinder 7. A leak-proof plate 10 is provided below the lifting frame 8 through a connecting rod 9. The bottom wall of the leak-proof plate 10 is smooth.

[0021] Both the lifting frame 8 and the leak-proof plate 10 are provided with openings corresponding to the filling pipe 11. The filling pipe 11 is connected to the lifting frame 8 through the connecting frame 12 and the second cylinder 13. Both sides of the outer wall of the moving plate 6 are provided with drag grooves 19. The drag grooves 19 are provided with anti-detachment rods 14 through elastic mechanisms. Both sides of the outer wall of the bottom plate 1 are provided with anti-detachment grooves 15.

[0022] The transmission mechanism includes a drive gear 21 mounted on the output shaft of the drive motor 20, and a transmission gear 22 that meshes with the drive gear 21 at the end of the adjusting screw 23. As shown in the figure, both the drive gear 21 and the transmission gear 22 are bevel gears.

[0023] The first limiting mechanism includes a first limiting rod disposed in the clamping groove 2. The first limiting rod slides through the adjusting plate 3. The first limiting rod is arranged parallel to the adjusting screw 23, which realizes the limiting of the adjusting plate 3, thereby preventing it from rotating with the adjusting screw 23.

[0024] The second limiting mechanism includes a second limiting rod disposed in the moving groove 5. The second limiting rod slides through the moving nut 17. The second limiting rod is parallel to the moving screw 16, which limits the moving nut 17 and prevents it from rotating with the moving screw 16.

[0025] The insertion mechanism includes a rod mounted on the movable nut 17, and a slot corresponding to the rod is provided on the bottom wall of the movable plate 6. When the rod is inserted into the slot, the movable nut 17 can move to drive the movable plate 6 to move.

[0026] The elastic mechanism includes a spring 18 disposed in the drag groove 19. The two ends of the spring 18 are elastically connected to the outer wall of the anti-detachment rod 14 and the inner wall of the drag groove 19, respectively. The spring 18 can realize the dragging operation of the anti-detachment rod 14, which has a U-shaped design.

[0027] When using this utility model, such as Figure 1 As shown, the bottle is placed on the base plate 1. The drive motor 20 is started, causing it to drive the drive gear 21 to rotate. The drive gear 21, in conjunction with the transmission gear 22, drives the adjusting screw 23 to rotate. When the adjusting screw 23 rotates, the adjusting plate 3 on its outer wall moves in conjunction with the clamping plate 4 to clamp and fix the bottle. In this scheme, the filling tube 11 is connected to the filling machine to realize the filling operation. The filling machine is not shown in this scheme because it is an existing technology product and will not be described in detail. Subsequently, the second cylinder 13 drives the connecting frame 12 and the filling tube 11 to descend so that their height is lower than the leak-proof plate 10. Then, the first cylinder 7 retracts, driving the leak-proof plate 10 and the filling tube 11 to descend. Finally, the filling tube 11 is completely inserted into the bottle, and the leak-proof plate... The bottom wall of the bottle 10 is in close contact with the upper surface of the bottle mouth. Then, quantitative filling is carried out by the filling machine. After filling, the second cylinder 13 extends and drives the filling tube 11 to separate from the bottle. The object on the outer wall of the filling tube 11 is scraped off by the leak-proof plate 10 and accumulates on the bottom wall of the leak-proof plate 10. Then, the power device connected to the moving screw 16 in the moving groove 5 is activated. The power device drives the moving screw 16 to rotate. When the moving screw 16 rotates, the moving nut 17 on its outer wall drives the moving plate 6 to move. The moving plate 6 drives the leak-proof plate 10 to move relative to the bottle. The object on the bottom wall of the leak-proof plate 10 is scraped off by the bottle mouth and smoothly enters the bottle, thus completing one filling operation and preventing leakage.

[0028] Reversing the drive motor 20 will cause the adjusting plate 3 to move the clamping plate 4 to release the clamping and fixing operation on the bottle, so as to remove and replace the bottle after filling.

[0029] Pulling the anti-detachment rod 14 will cause the part of the drag spring 18 that is in the anti-detachment groove 15 to detach from the anti-detachment groove 15. Then, lifting the moving plate 6 will cause it to drive the filling tube 11 and other components to detach from the base plate 1. After a large number of components are detached from the base plate 1, the device changes from a whole to a set of parts, which makes it convenient to move, transport and store the device.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
