step four, filling two kinds of liquid into the tank body 10 by using a liquid spraying head, and sealing the filling opening 11; and

and step five, the tank body 10 is flatly laid on the transmission track 31, two gear rings 12 on the tank body 10 are respectively meshed with the racks 311 in the two transmission grooves, and the two racks 311 are used for guiding the tank body 10 to roll and transmit.

In the filling transfer method, the positioning assembly 23 positions the can body 10 on the bottom plate 21. The gear drive assembly 25 is engaged with the two gear rings 12 on the can body 10 to drive the can body 10 to rotate, so that the filling opening 11 of the can body 10 is aligned with the liquid spraying head to perform the filling operation. Thereafter, the can body 10 is laid on the transfer rail 31 such that the racks 311 in the two transfer grooves are engaged with the two ring gears 12 on the can body 10, respectively, to guide the can body 10 for rolling transfer. Because the gear drive assembly 25 is matched with the two gear rings 12 when the tank body 10 is rotated to align the filling opening 11 with the liquid spraying head, the tank body 10 cannot slip, and the rotation precision of the tank body 10 is improved. When the tank body 10 is conveyed, the two racks 311 are meshed with the two gear rings 12, so that any end of the tank body 10 is not easy to slip, the rolling collimation of the tank body 10 is kept, the tank body does not roll out of a track or impact the side wall of the track in a tilting mode, and the conveying safety of the tank body 10 is improved.

For example, it is particularly important that the driving motor 251 is also used for driving the two gears 253 to rotate during the process that the arc-shaped positioning arm 233 pushes the tank 10 to move towards the arc-shaped rib 215, so that the two gears 253 are respectively meshed with the two gear rings 12, the meshing tightness of the two gears 253 on the moving tank 10 is ensured, and the stress balance of the tank 10 is improved. On the one hand, it is ensured that the can body 10 is not prone to toppling due to the bottom force alone, and on the other hand, it is also ensured that the two toothed wheels 253 are already engaged with the two toothed rings 12 in advance when the rotational alignment action is subsequently performed, so that the can body 10 can rotate in time.

For example, in order to improve the mixing uniformity of two liquids in the tank 10, for example, a suspension liquid is contained in the tank 10, the tank transporting mechanism 30 further includes a mixing shell 32, the transporting track 31 is disposed obliquely and includes a starting end 314 and a terminating end 316 which are disposed oppositely, the height position of the starting end 314 is greater than that of the terminating end 316, and the mixing shell 32 is mounted at the terminating end 316 of the transporting track 31. The bottom of mixing shell 32 is provided with mount pad 324, mount pad 324 installs on subaerial, be formed with convex guide board 321 in the mixing shell 32, the relative both sides of guide board 321 are formed with respectively to keep off and establish lateral wall 322, two keep off and establish and all seted up the circular shape on the lateral wall 322 and draw forth mouth 323.

A lead-in opening 3216 is opened at one side of the guide plate 321 facing the conveying rail 31, and a lower side edge of the lead-in opening 3216 is aligned with a bottom surface of the conveying rail 31. An arc-shaped blocking cover 3217 is disposed in the introducing port 3216, a top edge of the arc-shaped blocking cover 3217 is connected to a top edge of the introducing port 3216 through a torsion spring, the arc-shaped blocking cover 3217 is blocked in the introducing port 3216 to close the introducing port 3216, and a lower side edge of the arc-shaped blocking cover 3217 abuts against a lower side edge of the introducing port 3216, so that the arc-shaped blocking cover 3217 cannot be separated from the mixing casing 32 when being stressed, but can only rotate towards the inner side of the mixing casing 32. The arc-shaped blocking cover 3217 is configured to rotate inward under the impact of the can body 10 to expose the inlet 3216, so that the can body 10 enters the mixing shell 32 from the inlet 3216, the arc-shaped blocking cover 3217 automatically returns to the original shape after the can body 10 enters to close the inlet 3216, and the can body 10 rolls back and forth in the mixing shell 32 along the two engaging tracks 3215 to mix the two liquids in the can body 10 thoroughly until the can body 10 stops at the lowest position of the mixing shell 32. For example, the two engagement tracks 3215 extend to the arcuate flaps 3217 so that the can body 10 can roll on the arcuate flaps 3217. Through the arrangement of the arc-shaped blocking cover 3217, the can body 10 can rush into the mixing shell 32 from the terminating end 316, but cannot go out, but only can roll back and forth in the mixing shell 32 to consume the kinetic energy thereof, so that the can body is finally stopped, and the can body 10 can be conveniently intercepted, and the collision of the can body 10 is not required to be borne through the guiding of the mixing shell 32. Moreover, the mixing shell 32 is more important for the purpose of enabling the tank 10 to roll back and forth therein, thereby improving the mixing effect of the two liquids in the tank 10.

For example, in order to facilitate the rapid stopping and positioning of the can body 10 after the speed of the can body 10 is reduced, i.e., the speed of the back-and-forth rolling is reduced, the two ring gears 12 on the can body 10 are provided with the crack grooves 128, and the crack grooves 128 penetrate through the ring gears 12.

The two crack slots 128 on the can body 10 are used for aligning to the middle point of the guide plate 321, and the stop bar 42 is used for being driven by the stop cylinder 41 to be lifted and inserted into the two crack slots 128, so that the can body 10 is stopped by the stop bar 42, and the can body 10 is stopped at a faster speed. The pushing assembly 50 includes a mounting bracket 51, a pushing cylinder 52 and a pushing circular plate 53, wherein the mounting bracket 51 is mounted on the mounting base 324 and protrudes to one side of the mixing shell 32, the pushing cylinder 52 is mounted on the top of the mounting bracket 51, the pushing circular plate 53 is disposed in one of the outlet openings 323 and connected to an output shaft of the pushing cylinder 52, and the pushing cylinder 52 is configured to drive the pushing circular plate 53 into the mixing shell 32 and apply force to an end of the can body 10, so as to push the can body 10 out of the other outlet opening 323 along the stopper bar 42. The mixing shell 32 can improve the mixing effect of the two liquids in the can body 10, and the stop assembly 40 can stop the can body 10 at a higher speed and guide the pushing direction of the can body 10. The pushing assembly 50 facilitates pushing the can 10 out of the mixing housing 32 for further operation.

For example, the filling transmission method further includes the steps of:

step six, the can body 10 impacts the arc-shaped blocking cover 3217 at the terminating end 316 of the conveying track 31 to rotate inwards to expose the introduction port 3216, the can body 10 enters the mixing shell 32 from the introduction port 3216, the arc-shaped blocking cover 3217 automatically returns to the original shape to close the introduction port 3216 after the can body 10 enters, and the can body 10 rolls back and forth in the mixing shell 32 along the two engaging tracks 3215 to fully and uniformly mix the two liquids in the can body 10;

seventhly, the stopping bar 42 is driven by the stopping cylinder 41 to ascend and is inserted into the two crack grooves 128, so that the stopping bar 42 is used for stopping and positioning the can body 10, and the can body 10 stops rolling back and forth; and

step eight, the pushing cylinder 52 drives the pushing circular plate 53 to enter the mixing shell 32, and applies force to the end of the can body 10, so as to push the can body 10 out of the other drawing-out opening 323 along the stop strip 42.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
