Description

Technical Field

[0001] This utility model relates to the technical field of ampoule drawing and filling machines, specifically to a bottle mouth sealing mechanism for an ampoule drawing and filling machine. Background Technology

[0002] As a common pharmaceutical packaging container, the sealing quality of ampoules directly affects the sealing, safety, and shelf life of pharmaceuticals. In the ampoule filling process, the pinching of the bottle mouth and the removal of waste are key steps.

[0003] Currently, common bottle-sealing mechanisms in wire drawing and filling machines typically employ a clamping mechanism to knead and seal the heated and softened bottle neck. However, existing technologies generally suffer from problems such as waste material adhesion and clamp contamination, leading to poor sealing end-face quality. Specifically, during the kneading process, molten glass waste easily adheres to the surface of the clamping components. With continuous production, the accumulation of these residual waste materials significantly reduces the cleanliness of the clamping surface. This adhered waste material not only directly affects the normal working condition of the clamping components but also causes uneven force and inaccurate positioning during subsequent bottle neck kneading, resulting in an uneven and irregular sealing end-face, affecting sealing quality and appearance.

[0004] Therefore, there is an urgent need for a bottle sealing mechanism that is simple and efficient, can effectively prevent waste adhesion, and ensures the continuous cleanliness of the clamping components, thereby significantly improving the neatness of the ampoule sealing end face and the overall sealing quality.

[0028] Reference Figure 1-4 As shown, this utility model provides a technical solution for the bottle neck sealing mechanism of an ampoule drawing and filling machine:

[0029] Reference Figure 1 and Figure 2 As shown, an ampoule filling and sealing machine includes a bottle neck sealing mechanism, comprising an outer shell 1 with an opening on the bottom surface and bottle neck clamping assemblies on both the left and right side walls of the outer shell 1. It should be noted that the outer shell 1 has an inner cavity.

[0030] The bottle-clamping assembly includes a motor 2 and a telescopic component 3. The motor 2 and telescopic component 3 are mounted on the outer wall of the outer casing 1 via fasteners 12. An output shaft 21 is connected to the output end of the motor 2, and a pinion 22 is sleeved through the side wall of the outer casing 1 via the output shaft 21. It should be noted that the fastener 12 includes a top arc support plate and a bottom ring sleeve. The top arc support plate and the bottom ring sleeve are fixedly connected. The side end of the top arc support plate is fixedly connected to the side wall of the outer casing 1, and the top arc support plate is fixedly connected to the motor. The bottom ring sleeve is fixedly connected to the telescopic component 3 via an interference fit.

[0031] The telescopic component 3 includes a telescopic shaft 31. An outward-moving clamping plate 32 is provided at the end of the telescopic shaft 31 that passes through the side wall of the outer shell 1. A collar post 36 and an inner rotating clamping plate 33 are slidably connected on the telescopic shaft 31. The collar post 36 is fixedly connected to the inner rotating clamping plate 33. The collar post 36 is rotatably connected to the side wall of the outer shell 1. A large gear 34 is sleeved on the collar post 36.

[0032] Reference Figure 2 As shown, the large gear 34 meshes with the small gear 22 for transmission.

[0033] It should be noted that the inner rotating clamp 33 is located inside the outer shell 1, and the large gear 34 and the small gear 22 are both located inside the outer shell 1.

[0034] Reference Figure 1-4 As shown, in an optional embodiment, a fan plate 37 is provided on the side wall of the inner rotating clamp 33, and the fan plate 37 is located above the outer moving clamp 32 and the inner rotating clamp 33.

[0035] Reference Figure 2 and Figure 3 As shown, in an optional embodiment, limiting collars 35 are fitted on both the inner and outer sides of the collar post 36 located on the side wall of the outer shell 1, so as to realize the collar post 36 rotatably connected to the side wall of the outer shell 1.

[0036] Reference Figure 2 As shown, in an optional embodiment, the number of teeth on the pinion 22 is less than the number of teeth on the gear 34. With this design, the rotation frequency of the motor 2 is reduced while satisfying the swing frequency of the inner rotating clamp 33, making the motor 2 more durable.

[0037] It should be noted that the internal width of the outer shell 1 is greater than the width of the inner rotating clamp 33, as shown in the reference. Figure 4 As shown, this design allows the inner rotating clamp 33 to swing inside the outer shell 1 to match the operating conditions required by the mechanism.

[0038] Reference Figure 1As shown, in an optional embodiment, motor 2 can be a DC motor or a stepper motor. It should be noted that both DC motors and stepper motors can rotate in both directions, thereby driving the output shaft 21 to rotate in both directions to match the operating conditions of this mechanism.

[0039] It should be further explained that the telescopic shaft 31 is non-rotatable. Specifically, the telescopic shaft 31 does not rotate on the side wall of the outer casing 1. The telescopic component 3 can be a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. It should be noted that hydraulic cylinders, pneumatic cylinders, or electric actuators are all existing mature technologies and will not be elaborated on here. The telescopic shaft 31 is the movable end of the hydraulic cylinder, pneumatic cylinder, or electric actuator. This movable end can only move in extension and retraction, that is, the telescopic shaft 31 is non-rotatable. This is an existing mature technology and will not be elaborated on here.

[0040] Reference Figure 4 As shown, in an optional embodiment: the height of the inner rotating clamp 33 is not less than the height of the outer moving clamp 32, and the width of the outer moving clamp 32 is equal to the width of the inner rotating clamp 33. It should be noted that the inner rotating clamp 33 is set higher, so that the fan plate 37 has installation space and avoids the fan plate 37 interfering with the movement of the outer moving clamp 32.

[0041] Reference Figure 1 and Figure 2 As shown, in an optional embodiment, the top side of the outer shell 1 is symmetrically provided with lugs 11 for fixing the outer shell 1. It should be noted that the lugs 11 are provided with holes. When fixing the outer shell 1 in the appropriate position of the filling machine, the outer shell 1 can be fixed by passing existing bolts through the holes and tightening them.

[0042] The working principle of this mechanism will now be explained through its operation process: When using this mechanism, it is necessary to first briefly describe the object it is used to seal ampoules. On the wire drawing and filling machine, the top mouth of the ampoule is heated to a molten state by the high temperature of the burner. This mechanism squeezes the molten ampoule mouth to achieve the purpose of sealing.

[0043] The outer casing 1 is fixed to the appropriate position on the wire drawing and sealing machine using existing bolts and lugs 11. After the ampoule is heated to a molten state at the top of the bottle mouth by the high temperature of the burner, it runs on the wire drawing and sealing machine between the outer moving clamp 32 and the inner rotating clamp 33. Then, the telescopic component 3 is activated to control the telescopic shaft 31 to retract into the telescopic component 3, so that the outer moving clamp 32 moves closer to the inner rotating clamp 33, thereby pinching the molten ampoule mouth together and completing the sealing operation. After that, the sealed ampoule proceeds to the next step on the wire drawing and sealing machine, and the telescopic component 3 is activated again to control the telescopic shaft 31 to extend out of the telescopic component 3, so that the outer moving clamp 32 moves away from the inner rotating clamp 33, causing the ampoule mouth waste sandwiched between the outer moving clamp 32 and the inner rotating clamp 33 to fall off.

[0044] Before the next sealing operation, the telescopic component 3 is activated, and the telescopic shaft 31 is controlled to retract into the telescopic component 3, that is, the outer moving clamp 32 approaches the inner rotating clamp 33. At this time, the motor 2 is started and its output end is controlled to rotate intermittently. Through the transmission of the output shaft 21, and due to the engagement of the output shaft 21 and the large gear 34, the inner rotating clamp 33 swings left and right. Since the outer moving clamp 32 is close to the inner rotating clamp 33, the left and right swing of the inner rotating clamp 33 relative to the outer moving clamp 32 will cause the ampoule bottle mouth waste that is not completely detached from the outer moving clamp 32 or the inner rotating clamp 33 to detach from the outer moving clamp 32 or the inner rotating clamp 33 due to friction, thereby keeping the outer moving clamp 32 or the inner rotating clamp 33 clean. When the sealing operation is performed again, the squeezing of the bottle mouth waste on the molten bottle mouth is avoided, making the sealed end of the ampoule more neat, thereby improving the sealing quality of the ampoule.

[0045] It should be further explained that by setting the fan plate 37, when it swings left and right on the inner rotating clamp 33, the fan plate 37 will also swing around the central axis of the collar column 36, thereby generating airflow, which helps to remove the ampoule bottle mouth waste adhering to the outer moving clamp 32 or the inner rotating clamp 33.

[0046] This mechanism, through the arrangement and collaboration of an outer moving clamp 32, an inner rotating clamp 33, a motor 2, and a telescopic component 3, utilizes the telescopic component 3 to control the outer moving clamp 32 to approach the inner rotating clamp 33, thereby pinching the ampoule neck. The motor 2 controls the left and right swing of the collar column 36, which causes the adhering ampoule neck waste to detach due to friction, keeping the outer moving clamp 32 or the inner rotating clamp 33 clean, resulting in a neater sealing end of the ampoule. It not only achieves the sealing of the ampoule but also improves the sealing quality. The structure is simple and efficient, making it suitable for widespread application in wire drawing and sealing machines.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
