Description

Technical Field

[0001] The present invention relates to the technical field of disinfectant filling, and particularly to a disinfectant filling device. Background Art

[0002] An ideal disinfectant should have the characteristics of a broad bactericidal spectrum, strong bactericidal ability, fast action speed, good stability, low toxicity, low corrosiveness and irritation (should be non-toxic, residue-free, non-corrosive, non-irritating), be easily soluble in water, safe for humans and animals, inexpensive and easily available, and cause low environmental pollution.

[0003] After the disinfectant is produced, it needs to be filled. The existing method for filling the disinfectant on a production line is to introduce the disinfectant into a liquid storage tank. Then, a plurality of filling nozzle assemblies are connected to the bottom end of the liquid storage tank. A peristaltic pump is provided on each filling nozzle assembly. The filling bottles of the disinfectant move under the conveyance of a conveyor belt. When the filling bottle corresponds to the position of the filling nozzle assembly, the lifting device at the top of the filling nozzle assembly drives the filling nozzle assembly to move downward, and the filling nozzle assembly extends into the filling bottle. Then, the peristaltic pump is turned on, so that the disinfectant in the liquid storage tank is filled into the filling bottle through the filling nozzle assembly. Then, the lifting device drives the filling nozzle assembly to move upward to the initial state. After that, the conveyor belt conveys the filled filling bottle, thereby continuously filling the filling bottle.

The two through holes on the right mounting plate 13 correspond to the two through holes on the output shaft 14 in position. The two groups of pin shafts 16 are respectively installed at the left end of the handle block 15. The left ends of the two groups of pin shafts 16 pass through the two through holes of the right mounting plate 13 and are inserted into the two through holes of the output shaft 14. A lifting component is arranged on the rotating plate 8;

[0022] Place the filling bottle on the conveying mechanism 5. Then, the clamping assembly on the conveying mechanism 5 fixes the filling bottle. After that, the conveying mechanism 5 conveys the filling bottle. When the bottle mouth of the filling bottle corresponds to the position of the main filling nozzle assembly 2, the conveying mechanism 5 shuts down. Then, the lifting mechanism 3 is opened, and the output shaft 14 drives the main filling nozzle assembly 2 to move downward through two groups of pin shafts 16, the connecting block 15, the right mounting plate 13, and the right second connecting plate 12. The main filling nozzle assembly 2 extends into the bottle mouth of the filling bottle. After that, the peristaltic pump on the main filling nozzle assembly 2 is opened, and the disinfectant in the disinfectant tank 4 is introduced into the filling bottle through the peristaltic pump by the main filling nozzle assembly 2. After the filling of the disinfectant in the filling bottle is completed, the peristaltic pump on the main filling nozzle assembly 2 is closed. Then, the lifting mechanism 3 drives the main filling nozzle assembly 2 to move upward to the initial position through the output shaft 14, two groups of pin shafts 16, the connecting block 15, the right mounting plate 13, and the right second connecting plate 12. After that, the conveying mechanism 5 starts to convey the filling bottle. When a failure occurs in the main filling nozzle assembly 2 or the peristaltic pump thereon, the lifting assembly is opened. The lifting assembly contacts the left first connecting plate 11 and drives it to move upward. When the lifting assembly contacts the right first connecting plate 11, the two first connecting plates 11 are on the same horizontal plane. Then, the lifting assembly is closed. After that, the servo motor 7 is opened, and the servo motor 7 drives the rotating plate 8 to rotate. The rotating plate 8 drives the two first connecting plates 11 to rotate through four groups of fixed rods 9. The right first connecting plate 11 drives the main filling nozzle assembly 2 to rotate through the right second connecting plate 12, and the left first connecting plate 11 drives the auxiliary filling nozzle assembly 26 to rotate through the left second connecting plate 12. When the rotating plate 8 rotates 180 degrees and the auxiliary filling nozzle assembly 26 is in the initial position of the main filling nozzle assembly 2, the servo motor 7 is closed. Then, the two pin shafts 16 are inserted into the two through holes of the output shaft 14 through the two through holes of the mounting plate 13 through the connecting block 15 to fix the auxiliary filling nozzle assembly 26. After that, the lifting assembly is opened in the reverse direction, and the lifting assembly moves downward to the initial position. The whole main filling nozzle assembly 2 rotated to the left moves downward according to the lifting assembly. When the first connecting plate 11 on the side of the main filling nozzle assembly 2 contacts the rotating plate 8, the staff repairs the main filling nozzle assembly 2 or the peristaltic pump on the main filling nozzle assembly 2, and the auxiliary filling nozzle assembly 26 can continue to fill the filling bottle. By setting this device, when a failure occurs in the main filling nozzle assembly 2 or the peristaltic pump thereon, the auxiliary filling nozzle assembly 26 can replace the main filling nozzle assembly 2, which not only ensures the continuity of filling the disinfectant into the filling bottle but also facilitates the repair of the main filling nozzle assembly 2 and its peristaltic pump.

[0023] The disinfectant filling device of the present invention, the lifting assembly includes an electric cylinder 17, a moving plate 18 and two groups of lifting blocks 19. The electric cylinder 17 is installed at the bottom end of the rotating plate 8. The output end of the electric cylinder 17 is connected to the right side of the bottom end of the moving plate 18. The two groups of lifting blocks 19 are respectively installed on the left and right sides of the top end of the moving plate 18. The top ends of the two groups of lifting blocks 19 are in contact with the bottom ends of the two groups of first connecting plates 11.

[0024] By setting the electric cylinder 17, the moving plate 18 and the lifting blocks 19, when the electric cylinder 17 is opened, the moving plate 18 drives the two groups of lifting blocks 19 to move upward. The left lifting block 19 contacts the left first connecting plate 11 and drives the left first connecting plate 11 to move upward. When the right lifting block 19 contacts the right first connecting plate 11, the two groups of first connecting plates 11 are on the same horizontal plane. Then the electric cylinder 17 is closed. When the faulty main filling nozzle assembly 2 is rotated to the left, the electric cylinder 17 is opened in reverse. The moving plate 18 drives the two groups of lifting blocks 19 to move downward. The right lifting block 19 separates from the first connecting plate 11 on the auxiliary filling nozzle assembly 26. The first connecting plate 11 on the main filling nozzle assembly 2 always contacts the left lifting block 19 and moves downward following the moving plate 18. When the first connecting plate 11 on the main filling nozzle assembly 2 contacts the rotating plate 8, the electric cylinder 17 is closed, which plays a key role in replacing the main filling nozzle assembly 2 with the auxiliary filling nozzle assembly 26.

[0025] In the disinfectant filling device of the present invention, the left ends of the two groups of pin shafts 16 are provided with conical surfaces 20.

[0026] By setting the conical surfaces 20, it is convenient for the pin shafts 16 to pass through the through holes of the mounting plate 13 and insert into the through holes of the output shaft 14.

[0027] The disinfectant filling device of the present invention further includes a handle ring 21, and the handle ring 21 is installed at the right end of the handle block 15.

[0030] By setting the connecting rope 22, when the two groups of pin shafts 16 on the handle block 15 are detached from the output shaft 14 and the mounting plate 13, there is no need for someone to always hold the handle block 15 manually, which improves convenience.

[0031] The disinfectant filling device of the present invention further includes two groups of anti-slip rubber pads 23, and the two groups of anti-slip rubber pads 23 are respectively installed in the two through holes of the output shaft 14.

[0032] By setting the anti-slip rubber pad 23, the friction between the through hole of the output shaft 14 and the pin shaft 16 can be increased, thereby improving the stability of the pin shaft 16.

[0033] The disinfectant filling device of the present invention further includes a handle sleeve 24, and the handle sleeve 24 is installed inside the handle ring 21;

[0034] By setting the handle sleeve 24, the comfort of the staff holding the handle ring 21 can be improved.

[0036] By setting the linear bearings 25, the friction between the first connecting plate 11 and the fixing rod 9 can be reduced, making the first connecting plate 11 slide more smoothly on the fixing rod 9.

[0037] The disinfectant filling device of the present invention, when working, first places the filling bottle on the conveying mechanism 5, then the clamping assembly on the conveying mechanism 5 fixes the filling bottle, and then the conveying mechanism 5 conveys the filling bottle. When the bottle mouth of the filling bottle corresponds to the position of the main filling nozzle assembly 2, the conveying mechanism 5 is closed, and then the lifting mechanism 3 is opened. The output shaft 14 drives the main filling nozzle assembly 2 to move downward through two groups of pin shafts 16, the handle block 15, the right mounting plate 13 and the right second connecting plate 12. The main filling nozzle assembly 2 extends into the bottle mouth of the filling bottle. Then, the peristaltic pump on the main filling nozzle assembly 2 is opened, and the disinfectant in the disinfectant tank 4 is introduced into the filling bottle through the peristaltic pump by the main filling nozzle assembly 2. After the filling bottle is filled with disinfectant, the peristaltic pump on the main filling nozzle assembly 2 is closed, and then the lifting mechanism 3 drives the main filling nozzle assembly 2 to move upward to the initial position through the output shaft 14, two groups of pin shafts 16, the handle block 15, the right mounting plate 13 and the right second connecting plate 12. Then, the conveying mechanism 5 starts to convey the filling bottle. When a failure occurs in the main filling nozzle assembly 2 or the peristaltic pump thereon, the electric cylinder 17 is opened, and the moving plate 18 drives two groups of lifting blocks 19 to move upward.

The right first connecting plate 11 drives the main filling nozzle assembly 2 to rotate through the right second connecting plate 12, and the left first connecting plate 11 drives the auxiliary filling nozzle assembly 26 to rotate through the left second connecting plate 12. When the rotating plate 8 rotates 180 degrees and the auxiliary filling nozzle assembly 26 is located at the initial position of the main filling nozzle assembly 2, the servo motor 7 is closed, and then the two groups of pin shafts 16 are inserted into the two through holes of the output shaft 14 through the two through holes of the mounting plate 13 through the handle block 15 to fix the auxiliary filling nozzle assembly 26. Then, the electric cylinder 17 is opened in the reverse direction, and the moving plate 18 drives two groups of lifting blocks 19 to move downward. The right lifting block 19 separates from the first connecting plate 11 on the auxiliary filling nozzle assembly 26, and the first connecting plate 11 on the main filling nozzle assembly 2 always contacts the left lifting block 19 and moves downward following the moving plate 18. When the first connecting plate 11 on the main filling nozzle assembly 2 contacts the rotating plate 8, the electric cylinder 17 is closed, and the staff can repair the main filling nozzle assembly 2 or the peristaltic pump on the main filling nozzle assembly 2, and the auxiliary filling nozzle assembly 26 can continue to fill the filling bottle.
