Ampoule sealing mechanism

[0024] Example 1:

[0025] Such as Figure 1 to Figure 3 , An ampoule sealing mechanism provided by the present invention includes a bottle feeding mechanism and a bottle cap mounting mechanism on the side of the bottle feeding mechanism;

[0026] The bottle conveying mechanism includes a barrel-shaped stopper 3, a turntable 14 is provided in the stopper 3, a drive motor is connected to the turntable 14, and the edge of the turntable 14 is provided with a plurality of ring-shaped evenly distributed The ampoule bayonet 2 is provided with a bottle outlet slot 1 and a bottle inlet slot 8 on the side of the turntable 14. The bottle outlet slot 1 is a groove-like structure with side walls 102 on both sides and a bottom 103 on the bottom. The inner wall surface of the side wall 102 of the inlet end of the bottle outlet slot 1 is also provided with an arc stop 101, and the distance between the arc stop 101 and the bottom 103 decreases linearly from the inlet end to the other end of the bottle outlet slot 1 , The outlet end of the bottle outlet slot 1 and the inlet end of the bottle inlet slot 8 are connected with the turntable 14;

[0027] The bottle cap installation mechanism includes a frame 4, a hinge rod 5 hingedly connected to the frame 4, a cap holder 7 fixed on the hinge rod 5, and a cap feed slot 10 located above the cap holder 7. The frame 4 is also fixedly connected with an arc-shaped rail 13, the outer side of the arc-shaped rail 13 is an equal-diameter outer arc surface, and the side of the suction cover seat 7 close to the frame 4 is an inner surface that fits the equal-diameter outer arc surface. On the curved surface, the suction cover seat 7 is also provided with a suction pipe interface 9 and a suction port 12, the suction pipe interface 9 and the suction port 12 are communicated, and a motor 11 is also connected to the hinge rod 5.

[0028] Since the suction port works intermittently, in order to reduce the cost of the suction equipment adapted to the working state of the suction port 12, in this embodiment, the suction pipe interface 9 is connected with an air source hose. The other end is connected with an ejector, and the other inlet of the ejector is connected with a compressed air source. The on/off of the compressed air source and the ejector is controlled by a solenoid valve. In this way, the compressed air source can be softened when the air source is connected to the ejector. Negative pressure is generated in the tube to achieve the purpose of sucking the bottle cap at the suction port; a reversing device is also provided between the motor 11 and the hinge rod 5. Specifically, the rotor of the motor 11 is provided with two segments of gear teeth along its axial direction , The hinge rod is provided with one end of external teeth and one end of internal teeth, one of the gears meshes with the external teeth, the other end gear meshes with the internal teeth, and the meshing states of the two are staggered. The above structure facilitates the reversing rotation of the suction cap seat The arc-shaped rail 13 is set as a sector with a central angle of not less than 90°, and the central angle of the inner arc surface on the suction cover seat 7 is not less than 90°, and the suction port 12 is set on the suction cover seat 7 near the turntable 14 Side, and the equal-diameter outer arc surface of the arc-shaped rail 13 is connected to the turntable 14. The above arrangement can ensure that the suction cover seat 7 always does not deviate from the equal-diameter outer arc surface during the movement. At the same time, the arc-shaped rail 13 and the suction cover seat 7 Cast iron is used to prevent the arc-shaped rail 13 and the suction cap seat 7 from being corroded and to reduce the amount of wear between the two in the relative motion contact; the side of the inlet end of the bottle outlet groove 1 is also provided with a roller, which is used for manufacturing The combination of the ampoule and the bottle cap that moves through the arc-shaped stop 101 and the bottom edge 103 rotates, so that the bottle cap can smoothly penetrate into the ampoule during the movement of the combination.

[0029] Example 2:

[0030] This embodiment is further limited on the basis of embodiment 1: Figure 1 to Figure 3 In order to improve the working efficiency of the present invention, the tangent line of the point closest to the hinge rod 5 on the side of the turntable 14 is parallel to the hinge rod 5. There are two suction ports 12, and the distance between the suction ports 12 is any The distance between two adjacent ampoules 2 is equal.

[0031] In order to facilitate the suction of the bottle cap by the suction port 12, the bottle cap mounting mechanism further includes a blocking block 6 fixed on the suction cap seat 7 and located below the suction port 12.

[0032] Example 3:

[0033] This embodiment is further limited on the basis of embodiment 1: Figure 1 to Figure 3 , The bottle cap feeding tank 10 has a T-shaped groove shape. The bottle cap feeding tank 10 is arranged in a T-shaped groove, and the wider side of the bottle cap is placed in the bottle cap feeding tank 10 during use, so that the suction port 12 can only be adsorbed to the wider bottle cap One side, and the narrow side of the bottle cap itself is used to fit the ampoule, that is, the above arrangement also facilitates the installation of the cap.
