Description

Technical Field

[0001] This utility model relates to the field of ampoule production technology, and in particular to a wire drawing mechanism for an ampoule production line. Background Technology

[0002] Ampoule drawing is a key process in ampoule production, primarily used to seal the neck of the ampoule. A high-temperature flame is used to heat the neck of the ampoule, softening the glass material. Then, a drawing mechanism applies tension, drawing the softened glass into thin filaments that break, thus sealing the ampoule. This ensures that the medicine or other substances inside the ampoule are not affected by the external environment during storage and transportation, maintaining their quality and stability.

[0003] A search revealed Chinese patent number CN214566301U, which discloses an anti-scalding mechanism for an ampoule drawing machine. The mechanism includes a slide rail base with a sliding rod slidably connected to its inner wall. This invention places the ampoule in the middle of a clamping block, then pushes the sliding rod to move the clamping block. The clamping block clamps the ampoule by contacting the slide rail. The operator does not need to work near the high-temperature heating coil during use, thus improving the device's safety.

[0004] The above-mentioned clamping process is cumbersome and requires manual adjustment, which is time-consuming and labor-intensive. In addition, because it cannot adaptively clamp, the equipment debugging time is long when changing product specifications, resulting in the production line being idle. It is difficult to meet the needs of large-scale and diversified production, which limits the increase in production capacity. The lack of adaptive clamping force function makes it easy for excessive clamping force to cause scratches and cracks on the surface of the ampoule, reducing the product yield and increasing production costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 4This utility model provides a technical solution: a wire drawing mechanism for an ampoule production line, including a wire drawing device body 1 and a clamping mechanism 2 disposed on the inner side of one end of the wire drawing device body 1. The clamping mechanism 2 is used to adaptively clamp ampoules and adapt to ampoules of different sizes. The clamping mechanism 2 includes a base 21, which is fixedly connected to the upper surface of the wire drawing device body 1. Two sliders 22 are slidably connected to the inner side of the end of the base 21. A clamping arm 25 is fixedly connected to the upper surface of the slider 22. A clamping frame 26 is provided on one side of the clamping arm 25. Limiting blocks 23 are slidably connected to the inner sides of the two sliders 22. Trapezoidal protrusions are provided on the outer sides of both ends of the limiting blocks 23. A trapezoidal through groove is opened on the inclined structure of one side of the slider 22. 24. The trapezoidal protrusions on both sides of the limiting block 23 are set on the inner side of the trapezoidal through groove 24. Two sets of columnar structures are set on the outer side of the end of the clamping frame 26. The clamping frame 26 is slidably connected to the inner side of the top of the clamping arm 25 through the columnar structures. Two first springs 27 are fixedly connected to the outer side of one end of the clamping frame 26. The first springs 27 are sleeved on the outer side of the columnar structure on one side of the clamping frame 26. The outer side of the end of the first spring 27 is fixedly connected to the outer side of the top of the clamping arm 25. The clamping frame 26 is made of rubber and has an arc-shaped structure. One side of the clamping frame 26 is in contact with the outer side of the ampoule. A second spring 28 is fixedly connected to the lower surface of the middle part of the limiting block 23. The outer side of the end of the second spring 28 is fixedly connected to the inner side of the bottom end of the base 21.

[0024] When using this device to clamp ampoules, the user can place the ampoule inside the two clamping frames 26. At this time, the bottom of the ampoule contacts the upper surface of the limiting block 23. Under the action of the ampoule's weight, the limiting block 23 will descend vertically, compressing the second spring 28. When the limiting block 23 descends vertically, it will engage with the trapezoidal through slots 24 on both sides, pulling the two sliders 22 towards the center. At the same time, it will also move the clamping arms 25 on the upper surface of the sliders 22 towards the center. When the clamping arm 25 moves to the middle, and the clamping frame 26 on the outer side of the top of the clamping arm 25 contacts the outer side of the ampoule, the first spring 27 will be compressed until the first spring 27 is compressed to its maximum extent. At this time, the clamping arm 25 will not continue to move. At the same time, based on the support of the second spring 28, the limiting block 23 will not descend, so the ampoule can continue to be clamped adaptively. If the clamping force is too large, if the ampoule is small, the limiting block 23 will continue to descend until the clamping frame 26 contacts the outer side of the ampoule, so the size can be adapted.

[0025] like Figure 1 - Figure 4 As shown, the lower surface of the limiting block 23 is rotatably connected to two threaded rods 29. The threaded rods 29 pass through the through hole opened at the bottom end of the base 21, and the outer side of the threaded rods 29 is threaded with nuts 210.

[0026] After the limiting block 23 moves vertically downward to a certain extent, if the user needs to limit the position of the limiting block 23, the user only needs to rotate the nut 210 to move the nut 210 outside the threaded rod 29 until one side of the nut 210 contacts the lower surface of the base 21. At this time, the position of the limiting block 23 can be limited by the elastic potential energy stored in the second spring 28 and the limiting function of the nut 210, thus locking the device.

[0027] Working principle: When using this device to clamp ampoules, the user can place the ampoule to be clamped inside the two clamping frames 26. At this time, the bottom of the ampoule contacts the upper surface of the limiting block 23. Under the action of the ampoule's weight, the limiting block 23 will descend vertically, compressing the second spring 28. When the limiting block 23 descends vertically, it will cooperate with the trapezoidal protrusions on both sides and the trapezoidal through grooves 24, pulling the two sliders 22 towards the center. At the same time, it will move the clamping arm 25 on the upper surface of the slider 22 towards the center. When the clamping frame 26 on the outer side of the top of the clamping arm 25 contacts the outer side of the ampoule, it will compress the first spring 27 until the first spring 27 is compressed to its maximum extent. At this point, the clamping arm 25 will not continue to move, and based on the support of the second spring 28, the limiting block 23 will not descend, thus continuing to adaptively clamp the ampoule. If the clamping force is too large, a small ampoule will cause the limiting block 23 to continue descending until the clamping frame 26 contacts the outer side of the ampoule, allowing for adaptive sizing. Once the limiting block 23 has moved vertically downwards to a certain extent, if the user needs to limit the position of the limiting block 23, the user only needs to rotate the nut 210, causing the nut 210 to move outside the threaded rod 29 until one side of the nut 210 contacts the lower surface of the base 21. At this point, the elastic potential energy stored in the second spring 28 and the nut 210... The limiting function of the device can limit the position of the limiting block 23 and lock the device. Driven by the limiting block 23, components such as the slider 22 and clamping arm 25 can automatically adjust their positions according to the ampoule size, ensuring that the clamping frame 26 tightly fits ampoules of different diameters and heights. This eliminates the need for frequent manual clamp changes or parameter adjustments, effectively improving the production line's compatibility with diverse products, reducing equipment setup time, and increasing production efficiency. The linkage mechanism, triggered by the descent of the limiting block 23, pulls the slider 22 towards the center, ensuring that the ampoule is always centered on the slider 22 and clamping arm 25. This prevents positional shifts in subsequent processes such as stringing and sealing due to clamping deviations, ensuring the ampoule's integrity. To improve processing precision and product yield, the elastic buffer design of the first spring 27 and the second spring 28 limits the movement range of the clamping arm 25. When the clamping frame 26 contacts the outside of the ampoule and compresses the first spring 27 to its maximum extent, it automatically stops applying force, preventing the slider 22 from applying excessive pressure to the ampoule and preventing damage such as breakage or scratches. This ensures that the appearance and internal quality of the product are not affected, reduces the scrap rate, and prevents glass fragments from entering the equipment due to excessive clamping force causing the ampoule to break. It also reduces wear on mechanical parts such as the slider 22 and the limit block 23, reduces the probability of equipment failure and maintenance costs, extends the overall service life of the wire drawing mechanism, and ensures the stable operation of the production line.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
