Abstract
Description
Technical Field
[0001] This utility model relates to the field of chain device technology, specifically to a silent chain device for ampoules. Background Technology
[0002] The silent chain ampoule device is a key component in automated production or processing equipment for ampoules (a type of sealed small glass container commonly used to store injectable drugs) in pharmaceutical, medical, or laboratory environments. Its core function is to achieve efficient and stable transport of ampoules through a specially designed chain drive system, while significantly reducing operating noise.
[0003] Existing technology, patent document CN212075329U, provides a chain device for an intelligent suspension system, comprising a drive sprocket, a driven sprocket, and a chain. The chain includes multiple single-link chains and a connecting pin connecting adjacent chains. Each single-link chain is made of POM (polyoxymethylene) material and includes a pair of single-link plates, two inner pin holes on each single-link plate, and an outer expansion hole communicating with the inner pin holes. The diameter of the outer expansion hole is larger than the diameter of the inner pin holes. The connecting pin includes a pin shaft body that clearance-fits with the inner pin holes and limiting posts at both ends of the pin shaft body. The limiting posts and the outer expansion holes are interference-fitted. This invention features high structural strength and a secure connection, preventing single-link chains from detaching under stress during use, thus ensuring the efficient operation of the entire suspension system.
[0004] Although the device has many beneficial effects, it still has the following problems: During use, the chain needs to be pulled and bear tension for a long time. With long-term use, the fixed structure may gradually slip out or the connecting parts between the chains may break. The strength of the connecting parts is poor. At the same time, during the operation of the chain, the lack of a protective structure makes the chain susceptible to deformation when it is impacted, which may cause the chain to jam. Utility Model Content
[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.
[0006] 1. Technical problems to be solved:
[0007] To address the aforementioned issues, where the chain needs to be pulled during use and bear tension for extended periods, potentially leading to the gradual slippage of the fixed structure or breakage of the connecting parts between the chains, as well as the poor strength of the connecting parts themselves and the lack of protective structure on the chain during operation, which can cause the chain to deform upon impact and thus jam, the following measures are taken.
[0008] Therefore, the purpose of this utility model is to provide a silent chain device for ampoules. By using connecting plates, limiting nuts, and connecting rods on the back of the connecting plates on the front and back of the rotating shaft plate, the tensile strength of the connecting parts is enhanced. At the same time, the bearing structure inside the connecting plate provides tensile strength without affecting the normal rotation of the chain, thus strengthening the chain connecting parts. In addition, protective frames and protective rods are fixedly connected to the front and back of the chain plate, which protects the chain plate when it is impacted, making it less prone to deformation. Furthermore, the waterproof plate and oil-absorbing paper fixedly connected to the front of the protective rod can also absorb oil and prevent rust, resulting in good protective effect.
[0009] 2. Technical Solution:
[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:
[0011] A silent chain device for ampoules includes a pivot plate, a pivot rod movably connected inside the pivot plate, a pad movably connected to the outer circumference of the pivot rod, a connecting plate movably connected to the front of the pad, a connecting rod fixedly connected to the back of the connecting plate, a fixing plate connected to the inside of the connecting rod by bolts, an outer ring fixedly connected inside the connecting plate, an outer groove formed inside the outer circumference of the outer circumference of the pivot rod, an inner ring movably connected to the outer circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the inner circumference of the outer ...
[0012] In a preferred embodiment of the silent chain device for ampoules according to this utility model, multiple chain plates are movably connected to the outer circumference of the rotating shaft rod. A protective frame is fixedly connected to the front and back of the chain plates. A protective rod is fixedly connected inside the protective frame. A waterproof plate is fixedly connected to the front of the protective frame and the protective rod. Oil-absorbing paper is fixedly connected to the front of the protective frame and the protective rod.
[0013] As a preferred embodiment of the silent ampoule chain device of this utility model, the top and bottom of the chain plate are provided with grooves, and the inside of the chain plate is provided with combination holes. Through the grooves on the chain plate, some lubricating oil can remain inside the grooves, thereby indirectly improving the service life of the chain.
[0014] As a preferred embodiment of the silent chain device for ampoules according to this utility model, the back of the pad is provided with a chain plate, and there are gaps between multiple chain plates to facilitate the movement of the shaft plate. The pad restricts the distance between the chain plates, making it less likely to generate noise during operation.
[0015] As a preferred embodiment of the silent chain device for ampoules of this utility model, two fixing plates are fixedly connected to the front of the rotating shaft plate. The connecting rod is connected to the inside of the fixing plates by bolts. By using the two fixing plates and bolts to install the connecting rod on the front of the rotating shaft plate, the connecting plate can be pulled and held in place, making it less likely to gradually deviate due to rotation.
[0016] As a preferred embodiment of the silent chain device for ampoules of this utility model, the outer circumferential wall of the rotating shaft is movably connected with multiple rotating shaft plates, and gaps are left between the multiple rotating shaft plates to facilitate the movement of the chain plates. A pad is also provided on the front side of the rotating shaft plate, which can restrict the rotating shaft plate and make it less prone to noise.
[0017] As a preferred embodiment of the silent chain device for ampoules according to this utility model, the outer circumferential wall of the rotating shaft is connected with multiple rotating shaft plates and chain plates. The rotating shaft plates and chain plates connected to the outer circumferential wall of the same rotating shaft form a chain structure. By combining multiple chains together, the required chain length can be freely spliced. The splicing through the rotating shaft is also relatively convenient.
[0018] 3. Beneficial effects:
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This type of silent chain device for ampoules features a connecting plate, a limiting structure, and a connecting rod on the front of the rotating shaft plate. A bearing structure is fixedly connected inside the connecting rod. This allows the connecting plate to share the tensile force when the rotating shaft plate is under tension, and the connecting rod prevents it from shifting. In the event of a broken connecting part, the connecting plate temporarily bears the tensile force, facilitating timely repair of the chain. Furthermore, the bearing structure does not affect the normal rotation of the rotating shaft plate, thus strengthening the connection.
[0021] This type of silent chain device for ampoules features a protective frame and a protective rod fixedly connected to the front and back of the chain plate. When the surface of the chain plate is subjected to a large impact, the protective frame and the protective rod absorb the impact, thereby preventing deformation of the chain plate. At the same time, the waterproof plate and oil-absorbing paper fixedly connected to the front and back of the protective frame can absorb the residual moisture on the front of the chain plate after cleaning. The oil-absorbing paper can also absorb excess lubricating oil inside the grooves of the chain plate, preventing rust and excessive slippage due to excessive lubricating oil. The protective effect is good. Attached Figure Description

[0033] This utility model provides an overall structural schematic diagram of an embodiment of a silent chain device for ampoules, including:
[0034] Please see Figures 1-4 This embodiment of a silent chain device for ampoules includes a rotating shaft plate 1. A rotating shaft rod 2 is movably connected to the inside of the rotating shaft plate 1 via a rotating shaft. A pad plate 3 is movably connected to the outer circumference of the rotating shaft rod 2 via a rotating shaft. A connecting plate 10 is movably connected to the front of the pad plate 3 via a rotating shaft. A connecting rod 9 is welded to the back of the connecting plate 10.

Ball bearings 12 are provided inside the inner groove 15 and the outer groove 13. Limiting threads 16 are provided at both ends of the rotating shaft rod 2. Limiting nuts 17 are threadedly connected to the outer circumference of the limiting threads 16.
[0035] It is worth noting that, in order to protect the chain plate 4 from deformation due to impact, specifically, multiple chain plates 4 are movably connected to the outer circumference of the pivot rod 2 via a pivot. A protective frame 6 is glued and fixed to the front and back of the chain plate 4. A protective rod 7 is welded inside the protective frame 6. A waterproof board 19 is glued and fixed to the protective frame 6 and the protective rod 7. An oil-absorbing paper 20 is glued and fixed to the front of the protective frame 6 and the protective rod 7. The waterproof board 19 is made of polyvinyl chloride, and the oil-absorbing paper 20 is made of wood pulp fiber.
[0036] Next, in order to lock in some of the lubricating oil inside the chain plate 4 after it is sprayed, the top and bottom of the chain plate 4 are provided with grooves 5, and the inside of the chain plate 4 is provided with combination holes 18.
[0037] Meanwhile, in order to prevent the chain plate 4 and the pivot plate 1 from affecting each other, specifically, the back of the pad 3 is movably connected to the chain plate 4 through the pivot, and there will be gaps between multiple chain plates 4 to facilitate the movement of the pivot plate 1.
[0038] Furthermore, in order to prevent the connecting block from gradually deviating from its original position during rotation, specifically, two fixing plates 8 are welded to the front of the rotating shaft plate 1, and the connecting rod 9 is connected to the inside of the fixing plates 8 by bolts.
[0039] It is worth noting that, in order to prevent the chain plate 4 and the pivot plate 1 from making noise during operation, multiple pivot plates 1 are movably connected to the outer circumference of the pivot rod 2, and gaps are left between the multiple pivot plates 1 to facilitate the movement of the chain plate 4.
[0040] Finally, in order to freely combine the chain length, specifically, the outer circumference of the pivot rod 2 is connected with multiple pivot plates 1 and chain plates 4. The pivot plates 1 and chain plates 4 connected to the outer circumference of the same pivot rod 2 form a chain structure.
[0041] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.
[0042] Combination Figures 1-4 The specific usage process of the ampoule silent chain device of this embodiment is as follows:
[0043] 1. When using this type of ampoule silent chain device, the first step is to determine the chain length. Once determined, the rotating shaft 2 can be inserted between multiple chain plates 4 and rotating shaft plate 1, and the chain can rotate normally with the rotating shaft 2 as the center. At the same time, the pad plate 3 is installed to prevent the chain from making noise due to the collision between the chain plates 4 and the rotating shaft plate 1 while it is running. Next, the connecting plate 10 is installed on the circumferential surface of the rotating shaft 2, and the limiting nut 17 is tightened through the limiting thread 16. Then, the hole inside the connecting rod 9 is aligned with the hole of the fixing plate 8 that is fixedly connected to the front of the connecting plate 10, and the bolt is screwed in. Then, the rotating shaft 2 is installed in another hole between the rotating shaft plate 1 and the chain plate 4, and the above operation is repeated. In this way, the chain can be combined, and the chain length can be freely determined.
[0044] 2: When using this chain device, the front connecting plate 10 of the rotating shaft plate 1, together with the bearing structure, connecting rod 9 and limiting structure, allows the rotating shaft plate 1 to be pulled by the connecting rod 9 when rotating, making it less likely to deviate from its original position. At the same time, the bearing structure can also keep the rotating shaft plate 1 rotating normally, and the limiting structure further enhances the positioning effect of the device. The bearing structure includes: an outer ring 11, a ball 12, an outer slide groove 13, an inner ring 14, and an inner slide groove 15. The limiting structure includes: a limiting bolt and a limiting nut 17.
[0045] 3. During normal operation of the device, accidental operation may cause the chain to be subjected to a large impact, resulting in deformation of the chain plate 4 and bending of the chain plate 4. When impacted, the protective frame 6 and protective rod 7 on the outside of the chain plate 4 absorb the impact and protect the chain segments, thus preventing changes in the gap between the chain plate 4 and the pivot plate 1, which could cause the chain plate 4 or the pivot plate 1 to jam and become unusable. At the same time, a waterproof plate 19 is fixedly connected to the front of the protective frame 6 and the protective rod 7, which can absorb the moisture remaining on the front of the chain plate 4 after cleaning, preventing the chain plate 4 from rusting. In addition, the oil-absorbing paper 20 fixedly connected to the back of the protective frame 6 and the protective rod 7 can absorb some lubricating oil, preventing excessive lubricating oil residue inside the chain plate 4, which could cause the chain plate 4 to slip excessively when rotating around the pivot. The protection effect is good.
[0046] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
