Therefore, they should not be construed as limitations on this utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a filling mechanism for a bottle filling machine, including a crossbeam 1, a filling head and a lifting mechanism;

[0024] One end of the crossbeam 1 is connected to the connecting frame, which includes a slider 2, a connecting plate 3, and a lifting block 4. The slider 2 is connected to the crossbeam 1. The connecting plate 3 has a guide groove 5 along its length. The slider 2 and the guide groove 5 of the connecting plate 3 are slidably engaged. One end of the connecting plate 3 is connected to the lifting block 4. A vertical plate 6 is provided on the lower surface of the connecting plate 3 away from the lifting block 4. A reinforcing plate 20 is provided at the connection between the vertical plate 6 and the connecting plate 3 to ensure the structural strength and stability of the vertical plate 6. A bearing seat 7 is provided on the side of the lifting block 4 near the vertical plate 6. The bearing seat 7 is connected to the lead screw 8. One end of the lead screw 8 has an annular groove 21 along its circumference. The bearing seat 7 has a limit pin 22 along its radial direction. The limit pin 22 engages with the annular groove 21. The other end of the lead screw 8 has an internal hexagon head 23. This structure ensures the rotational connection between the lead screw 8 and the bearing seat 7 and prevents the lead screw 8 from detaching from the bearing seat 7. The lead screw 8 passes through the vertical plate 6 and is rotatably connected to the bearing seat 7. The bottom of the slider 2 is engaged with the lead screw 8 through a lead screw nut pair.

[0025] The filling head includes a filling tube 9, two or more connecting seats 10, and a sliding frame 11. The filling tube 9 is connected to the connecting seat 10. The top end of the filling tube 9 passes through the connecting seat 10 and is provided with a hose interface 19. The hose interface 19 is used to connect with the discharge hose of the filling machine, so as to realize the discharge from the filling tube 9. Each connecting seat 10 is connected to a sliding frame 11. The sliding frame 11 is slidably connected to the crossbeam 1. The rear side of the sliding frame 11 is provided with a screw 18 with a knob. The screw 18 is fastened to the crossbeam 1. By tightening the screw 18, the friction between the screw 18 and the crossbeam 1 is increased, thereby fixing the position of the sliding frame 11 and positioning the filling tube 9.

[0026] The lifting mechanism includes a top frame 12, a lead screw 13, a guide rod 14, and a servo motor 15. The servo motor 15 is mounted on the upper surface of the top frame 12. The output shaft of the servo motor 15 is connected to the top of the lead screw 13. The top frame 12 is also connected to the top of the guide rod 14. The lifting block 4 is engaged with the lead screw 13 through a lead screw nut pair. The guide rod 14 is engaged with the lifting block 4 for guidance. The bottom of the lead screw 13 is rotatably connected to the lead screw seat 16. The bottom of the guide rod 14 is connected to the guide rod seat 17. Fixing plates 24 are provided on both sides of the lead screw seat 16 and the guide rod seat 17. The connection between the lead screw seat 16 and the guide rod seat 17 and the side of the conveyor belt is achieved through the engagement of the fixing plates 24 and bolts.

[0027] Installation method and operating principle: Pass slider 2 through guide groove 5 of connecting plate 3, then pass lead screw 8 through vertical plate 6 and engage with lead screw nut pair of slider 2. At the same time, insert end of lead screw 8 into shaft seat 7 and engage with annular groove 21 through limit pin 22 to achieve limit of lead screw 8. Connect slide block to one end of crossbeam 1 with bolts. At this time, rotating lead screw 8 can drive crossbeam 1 to move along guide groove 5. Engage lead screw 13 with lead screw nut pair of lifting block 4, guide rod 14 with lifting block 4, and connect top of guide rod 14 to top frame 12. Install servo motor 15 on the upper surface of top frame 12, and connect top of lead cylinder to output shaft of servo motor 15 through coupling. Rotately connect lead cylinder seat to bottom of lead cylinder, fasten guide rod seat 17 to bottom of guide rod 14, and finally slide connecting connecting seat 10 with filling tube 9 to crossbeam 1 through slide frame 11 to complete assembly. Before use, connect the top frame 12 to the frame of the filling machine, and connect the guide rod seat 17 and the screw seat 16 to the side of the conveyor belt via the fixing plate 24 and bolts to complete the installation. During use, rotate the screw 8 according to the position of the bottle mouth. The screw 8 drives the slider 2 and the crossbeam 1 to move along the guide groove 5 of the connecting plate 3, aligning the filling tube 9 with the bottle mouth. Tighten the screw 18 with the knob. Simultaneously, adjust the distance between each connecting seat 10 according to the distance between the bottle mouths of two bottles, ensuring that each filling tube 9 corresponds to the bottle mouth of one bottle, completing the adjustment. During operation, when the bottle moves to below the filling tube 9 via the conveyor belt, the conveyor belt stops. The servo motor 15 drives the screw 13 to rotate, thereby driving the lifting block 4 to descend, allowing the filling tube 9 to be inserted into the bottle. Figure 5 As shown, the filling machine fills the liquid into each bottle. The servo motor 15 reverses, causing the lifting block 4 to drive the crossbeam 1 to rise, thereby causing each filling tube 9 to leave the bottle. The conveyor belt starts to fill the next batch of bottles. This utility model has a reasonable structure. The crossbeam 1 is connected to the slider 2, and the slider 2 is slidably connected to the guide groove 5 of the connecting plate 3. The bottom of the slider 2 is engaged with the lead screw 8 through a lead screw and nut pair. By rotating the lead screw 8, the position of the slider 2 and the crossbeam 1 can be adjusted, thereby adjusting the front and rear position of the filling tubes 9. At the same time, the filling tubes 9 are slidably connected to the crossbeam 1 through the connecting seat 10 and the sliding frame 11. The distance between the two filling tubes 9 can be adjusted according to the distance between the bottle mouths of the two bottles. There is no need to customize the connecting frame or disassemble and assemble the filling mechanism according to different bottles, which greatly improves the flexibility and applicability.
