DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] In the embodiment, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, a capping machine includes a bottle feeding mechanism 1, a cap feeding mechanism 2 is provided on one side of the bottle feeding mechanism 1, and further includes:

[0032] The first turntable 3 is arranged between the bottle feeding mechanism 1 and the cap feeding mechanism 2. The first turntable 3 is provided with a bottle taking station, a cap taking station, a cap screwing station and a bottle feeding station in sequence;

[0033] Positioning seats 4 are evenly distributed around the circumference of the first turntable 3;

[0034] A card slot 5 is provided on the positioning seat 5 and is used to cooperate with the bottle body;

[0035] The bottle taking robot 6 is arranged at the bottle taking station;

[0036] The capping robot 7 is arranged at the capping station;

[0037] The capping mechanism 8 is arranged at the capping station;

[0038] A limiting mechanism 9 is provided at the capping station for limiting the position of the bottle body;

[0039] The bottle-feeding robot 10 is arranged at the bottle-feeding station.

[0040] The bottle-taking robot 6 transports the bottle on the bottle-feeding mechanism 1 to the card slot 5 of the positioning seat 4, and then the No. 1 turntable 3 rotates, and the cap-taking robot 7 transports the bottle cap from the cap-feeding mechanism 2 to the top of the bottle body, and rotates the No. 1 turntable 3 again. The limiting mechanism 9 limits the bottle body and then the bottle cap is tightened by the capping mechanism 8. Finally, the bottle body with the cap screwed is transported to the bottle-feeding mechanism 1 by the bottle-feeding robot 10, realizing the automatic capping of spherical special-shaped bottles. The equipment is also suitable for capping various special-shaped small bottles.

[0041] In the embodiment, Figure 2 、 Figure 7 As shown, a flexible seat 11 is mounted on the positioning seat 4, and the card slot 5 is arranged on the flexible seat 11. The material of the flexible seat 11 is silicone or rubber to prevent damage to the bottle surface.

[0042] In the embodiment, Figure 2 、 Figure 3 As shown, the bottle-retrieving robot 6 includes a rotating arm 61 equipped with a first mounting plate 62 and a first power element 63 for driving the first mounting plate 62 up and down. A clamping cylinder 64 is mounted on the first mounting plate 62, and a clamping block 65 is mounted on the clamping cylinder 64. The first power element 63 is a cylinder, and the clamping block 65 is provided with an elastic layer. The first power element 63 is transferred to the bottle-delivering mechanism 1 via the rotating arm 61. The cylinder then descends, and the clamping cylinder 64 clamps the bottle, which is then transported to the slot 5 of the positioning seat 4 for securement. The bottle-delivering robot 10 has a similar structure to the bottle-retrieving robot 6, except that the clamping cylinder 64 is replaced with a vacuum suction cup.

[0043] In the embodiment, Figure 2 、 Figure 4 As shown, the cap removal robot 7 includes a first rotating shaft 71, a second mounting plate 72 disposed at the upper end of the first rotating shaft 71, a first vacuum suction cup assembly 73 disposed on either side of the second mounting plate 72, and a lifting device disposed at the lower end of the first rotating shaft 71. The first vacuum suction cup assembly 73 includes a vacuum suction cup and a mounting rod. The cap removal robot 7 can simultaneously remove caps from the cap feeding mechanism 2 and place caps on the first rotating disc 3, achieving high operating efficiency.

[0044] In the embodiment, Figure 2 、 Figure 4 As shown, the lifting mechanism includes a second turntable 12 with a cam slot 13 formed therein. A mounting seat 14 is provided at the bottom of the first rotating shaft 71, which is equipped with a roller 15 that engages with the cam slot 13. The rotation of the first rotating shaft 71 is driven by a motor that drives a synchronous pulley. This synchronous pulley, in turn, engages with a synchronous belt, which in turn drives the synchronous pulley on the first rotating shaft 71. The lifting of the first rotating shaft 71 is achieved by the rotation of the second turntable 12, and the roller 15 moves in the cam slot 13, thereby driving the lifting of the first rotating shaft 71.

[0045] In the embodiment, Figure 2 、 Figure 5 As shown, the capping mechanism 8 includes a liftable second shaft 81, which is equipped with a magnetic coupler 82. The magnetic coupler 82 is mounted on the capping head 83, and the capping head 83 is provided with a flexible sleeve 84 for engaging the bottle cap. The capping mechanism 8 also includes a housing, in which the second shaft 81 is mounted. The housing is equipped with a lifting rod. The lifting and lowering mechanism of the lifting rod is similar to that of the first shaft 71. The second shaft 81 is driven by a motor to rotate the helical gear assembly. When the bottle cap is subjected to a certain tightening force, the magnetic coupler 82 can rotate the capping head 3 relative to the second shaft 81. At the same time, the flexible sleeve 84 is made of silicone material to prevent damage to the bottle cap during the capping process.

[0046] In the embodiment, Figure 6 、 Figure 7 As shown, the limiting mechanism 9 includes a No. 2 vacuum suction cup assembly 91 and a No. 2 power element 92 for driving the No. 2 vacuum suction cup assembly to rise and fall. The bottom of the card slot 5 is provided with a No. 1 through hole 16, and the No. 1 turntable 3 is provided with a No. 2 through hole 17 for communicating with the No. 1 through hole 16. The No. 2 vacuum suction cup assembly 91 is arranged below the No. 1 turntable 3 and cooperates with the No. 2 through hole 17. The No. 2 power element 92 is a cylinder, which drives the No. 2 vacuum suction cup assembly 91 to rise. The vacuum suction cup blocks the No. 2 through hole 1 and absorbs air, sucking the bottle body located in the card slot 5 to prevent the bottle body from rotating during the capping process.

[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of illustrating the present invention and are not intended to limit the implementation methods of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to provide an exhaustive list of implementation methods. However, any obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
