Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a multi-specification ampoule injection solution filling fixture. Background Technology

[0002] Pharmaceutical equipment is a technical field that focuses on the design, research and development, manufacturing, application, and optimization of pharmaceutical equipment throughout the entire process of drug research and development and production. Its core objective is to provide specialized equipment that meets the requirements of safety, efficacy, and quality control in drug production, ensuring that every step from raw material processing to finished product packaging complies with industry standards such as Good Manufacturing Practices (GMP). When pharmaceutical companies need to produce multiple specifications of injectable solutions, and the order volume for each specification is not large, using multi-specification fixtures can avoid frequent replacements of core components of the entire filling production line. By simply adjusting or replacing the fixture's adapter module, production specifications can be quickly switched, significantly shortening changeover time and improving equipment utilization.

[0003] In existing technologies, some clamps are difficult to fix ampoules of different sizes. Since clamps are usually only compatible with one type of ampoule, when different sizes of products need to be produced, it takes a lot of time and manpower to change clamps, resulting in long downtime of the production line and reduced production efficiency. The inability of clamps to effectively fix ampoules of different sizes can lead to inaccurate relative positions between the ampoule and the filling needle, resulting in overfilling or underfilling of the drug solution, making it difficult to ensure the accuracy of the drug dosage. At the same time, the shaking or displacement of the ampoule may cause the filling needle to collide with the bottle mouth, producing glass fragments and contaminating the drug solution. Therefore, a multi-size ampoule injection solution filling clamp is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-specification ampoule injection liquid filling fixture, which aims to improve the problem that some fixtures in the prior art are difficult to fix different ampoules.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-specification ampoule injection liquid filling fixture includes a base, a support seat is installed on the top right side of the base, and an adjusting clamping mechanism is installed on both the front and rear sides of the top of the support seat. A load-bearing column is fixedly connected to the top left side of the base, and a feeding mechanism is installed inside the load-bearing column. The adjusting clamping mechanism includes a fixed box, the bottoms of two fixed boxes are fixedly connected to the top right side of the base, a sliding square column is slidably connected inside the fixed box, a moving plate is fixedly connected to the far side of the two sliding square columns, a telescopic spring is provided inside the fixed box, a moving frame is fixedly connected to the near side of the two sliding square columns, and a drive assembly is fixedly connected to the top of the moving frame. As a further description of the above technical solution: The drive assembly includes a motor, the bottom of which is fixedly connected to the top of the movable frame, a rotating rod is fixedly connected to the drive end of the motor, and a fixed sleeve is fixedly connected to the outside of the rotating rod. As a further description of the above technical solution: The feeding mechanism includes a second motor, the bottom of which is fixedly connected to the top left side of the base. A rotating plate is fixedly connected to the top of the second motor. Support frames are fixedly connected to the front and rear sides of the outer side of the load-bearing column. A fixed shaft is fixedly connected inside the support frame. Arc-shaped plates are fixedly connected to the front and rear sides of the fixed shaft. Multiple support plates are fixedly connected inside the load-bearing column. Feed baffles are fixedly connected to adjacent sides of the multiple support plates. Limit plates are fixedly connected to the outside of the feed baffles. A feed port is fixedly connected to the right side of the load-bearing column. As a further description of the above technical solution: One side of the telescopic spring is fixedly connected to the inner wall of the fixed box, and the other side of the telescopic spring is fixedly connected to one side of the movable plate. As a further description of the above technical solution: The movable plate is slidably connected to the inner wall of the fixed box, and the bottom of the movable frame is slidably connected to the top of the support base. As a further description of the above technical solution: The upper and lower sides of the fixed sleeve are rotatably connected to the inner wall of the movable frame, and the outer side of the rotating rod is rotatably connected to the inside of the movable frame. As a further description of the above technical solution: The rotating plate is rotatably connected to the inside of the load-bearing column, and the top of the rotating plate is in contact with the bottom of the feed baffle. As a further description of the above technical solution: The bottom of the fixed shaft is rotatably connected to the top of the rotating plate, and the bottom of the arc-shaped plate is in contact with the top of the rotating plate.

[0006] This utility model has the following beneficial effects: In this invention, the telescopic springs inside the two fixed boxes automatically adjust the telescopic amount according to the actual diameter of the ampoule, thereby pushing the moving frames on both sides to move in opposite directions. This achieves the fixation of ampoules of different specifications. The adaptive adjustment fixture can quickly adapt to ampoules of different specifications without the need for extensive manual adjustments or component replacements required by traditional fixtures. This significantly shortens changeover time, allowing the production line to switch to the production of different specifications more quickly, improving equipment utilization and production efficiency. Through adaptive adjustment, the fixture can automatically adjust the clamping force according to the shape and material of the ampoule, avoiding excessive compression or damage to the ampoule, protecting its integrity, and preventing problems such as liquid contamination or poor sealing caused by bottle breakage or bottle mouth deformation, thus improving the product qualification rate.

[0007] In this invention, a rotating plate driven by a second motor rotates at a constant speed inside a support column. The operator places the ampoules to be filled into the support column through the inlet. The ampoules slide down the inclined angle of the inlet baffle and finally land on the top of the rotating plate. As the rotating plate rotates, the ampoules are carried to the bottom of an arc-shaped plate. The arc-shaped plate is fixed inside the support frame by a fixed shaft. Its arc-shaped structure provides lateral restraint for the ampoules on the rotating plate, preventing them from tipping over or shifting during rotation. Simultaneously, the restraint plate and the inlet baffle work together to achieve automatic ampoule feeding, enabling rapid ampoule feeding without manual individual feeding, significantly shortening feeding time, meeting the continuous production needs of the production line, and improving production efficiency.

[0010] 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.

[0011] Reference Figures 1 to 3 This utility model provides an embodiment of a multi-specification ampoule injection solution filling fixture, including a base 1. The base 1 provides stable support for the entire fixture, bearing the weight of all components such as the support seat 2 and the load-bearing column 4, ensuring that there is no overall displacement or shaking during operation. The support seat 2 is installed on the top right side of the base 1. The support seat 2 provides an installation platform for the adjustable clamping mechanism 3, restricting the sliding direction of the moving frame 36 and ensuring that the moving frame 36 drives the drive component 37 to move smoothly to clamp the ampoule. Adjustable clamping mechanisms 3 are installed on both the front and rear sides of the top of the support seat 2. The adjustable clamping mechanisms 3 can be adjusted according to different specifications of the ampoule. The clamping range is automatically adjusted, and the moving frame 36 is driven by the elastic force of the telescopic spring 35 to achieve stable clamping of ampoules of different diameters. A load-bearing column 4 is fixedly connected to the top left of the base 1. The load-bearing column 4 provides installation space for the components of the feeding mechanism 5, limits the movement range of the ampoules during the feeding process, and prevents the ampoules from leaving the conveying path during feeding. The feeding mechanism 5 is installed inside the load-bearing column 4. The feeding mechanism 5 drives the rotating plate 52 to rotate through the motor 2 51. Together with the arc plate 55, the feeding baffle 57 and other components, it realizes the orderly conveying and directional arrangement of ampoules, and conveys the ampoules to be filled in the subsequent clamping process.

[0012] The adjusting clamping mechanism 3 includes a fixed box 31, which provides a closed installation space for the sliding square column 33, the moving plate 34, and the telescopic spring 35, restricting the movement trajectory of these components and preventing them from leaving the preset position during operation. It also protects the internal components from external interference. The bottoms of the two fixed boxes 31 are fixedly connected to the top right side of the base 1. The sliding square column 33 is slidably connected inside the fixed box 31, connecting the moving plate 34 and the moving frame 36. The sliding square column 33 transmits the sliding movement of the moving plate 34 to the moving frame 36, allowing the moving frame 36 to move synchronously with the moving plate 34, thereby adjusting the clamping position. The moving plate 34 is fixedly connected to the opposite side of each of the two sliding square columns 33. The moving plate 34 slides on the inner wall of the fixed box 31, compressing or stretching the telescopic spring 35 to obtain elastic force, and driving the moving frame 36 to move through its connection with the sliding square column 33, thus adjusting the clamping position. 6 provides the moving power. The fixed box 31 is equipped with a telescopic spring 35. The telescopic spring 35 generates elastic force through its own extension and contraction. When the diameter of the ampoule changes, the elastic force pushes or pulls the moving plate 34, so that the moving frame 36 automatically adjusts its position to achieve adaptive clamping for ampoules of different specifications. The moving frame 36 is fixedly connected to the adjacent side of the two sliding square columns 33. The moving frame 36 provides installation support for the drive component 37, driving the drive component 37 to move towards the ampoule. At the same time, its bottom slides on the top of the support base 2 to ensure that the drive component 37 can smoothly approach and contact the ampoule, and help stabilize the ampoule's posture. The top of the moving frame 36 is fixedly connected to the drive component 37. The drive component 37 drives the rotating rod 39 and the fixed sleeve column 32 to rotate through the motor 38. The friction between the fixed sleeve column 32 and the outer wall of the ampoule is used to limit the displacement of the ampoule during the filling process and maintain the stable posture of the ampoule.

[0013] The drive assembly 37 includes a motor 38, which provides power to the drive assembly 37 by converting electrical energy into mechanical energy. This motor drives the rotating rod 39 to rotate, which in turn rotates the fixed sleeve 32, providing power for the frictional stability between the fixed sleeve 32 and the ampoule. The bottom of the motor 38 is fixedly connected to the top of the moving frame 36. The driving end of the motor 38 is fixedly connected to the rotating rod 39, which connects the motor 38 and the fixed sleeve 32. The rotating rod 39 transmits the rotational power of the motor 38 to the fixed sleeve 32, allowing the fixed sleeve 32 to rotate synchronously with the motor 38, ensuring frictional stability. The rotating rod 39 is externally fixed... A fixed sleeve 32 is connected, which is in direct contact with the outer wall of the ampoule. Its rotation direction is opposite to the offset trend of the ampoule. The friction force prevents the ampoule from offsetting, and at the same time avoids direct contact damage to the outer wall of the ampoule. One side of the telescopic spring 35 is fixedly connected to the inner wall of the fixed box 31, and the other side of the telescopic spring 35 is fixedly connected to one side of the moving plate 34. The outer side of the moving plate 34 is slidably connected to the inner wall of the fixed box 31. The bottom of the moving frame 36 is slidably connected to the top of the support base 2. The upper and lower sides of the fixed sleeve 32 are rotatably connected to the inner wall of the moving frame 36, and the outer side of the rotating rod 39 is rotatably connected to the inside of the moving frame 36.

[0014] Reference Figure 1 , Figure 2 and Figure 4 The feeding mechanism 5 includes a second motor 51, which provides power to the feeding mechanism 5 and drives the rotating plate 52 to rotate at a constant speed inside the support column 4. This ensures that the ampoules can be continuously and orderly conveyed, avoiding interruptions in feeding and affecting filling efficiency. The bottom of the second motor 51 is fixedly connected to the top left side of the base 1, and the top of the second motor 51 is fixedly connected to the rotating plate 52. The rotating plate 52 carries the ampoules by rotating, conveying the ampoules entering from the inlet 59 to below the arc-shaped plate 55, and then transferring them to the discharge position on the right side of the support column 4, thus realizing the movement and conveying of the ampoules. Support frames 53 are fixedly connected to the front and rear sides of the external side of the support column 4. The support frames 53 provide installation support for the fixed shaft 54, stabilizing the fixed shaft 54. The fixed shaft 54 ​​is fixed to the outside of the load-bearing column 4 to ensure that the arc plate 55 can be kept in a fixed position through the fixed shaft 54, thereby achieving lateral restraint of the ampoule. The fixed shaft 54 ​​is fixedly connected inside the support frame 53. The fixed shaft 54 ​​fixes the position of the arc plate 55 so that the arc plate 55 can be stably placed above the rotating plate 52. At the same time, its bottom contacts the top of the rotating plate 52, which does not affect the rotation of the rotating plate 52 while providing stable support for the arc plate 55. The arc plates 55 are fixedly connected to the front and rear sides of the fixed shaft 54. The arc plate 55 uses the arc structure to laterally block the ampoule on the rotating plate 52, preventing the ampoule from tipping or shifting due to centrifugal force when the rotating plate 52 rotates, and ensuring that the ampoule is transported in a uniform posture.

[0015] Multiple support plates 56 are fixedly connected inside the load-bearing column 4. These support plates 56 provide mounting support for the feed baffle 57, ensuring it maintains a fixed tilt angle and allowing ampoules to slide smoothly down the feed baffle 57 to the top of the rotating plate 52. Feed baffles 57 are fixedly connected to adjacent sides of the support plates 56. The feed baffles 57 are tilted, guiding the ampoules down from the feed inlet 59 towards the rotating plate 52, limiting their movement during the initial feeding stage, and preventing them from piling up or distributing haphazardly within the load-bearing column 4. A limiting plate 58 is fixedly connected to the outside of the feed baffle 57. The limiting plate 58 cooperates with the feed baffle 57 to further reduce the size of the ampoule. The moving space limits the sliding trajectory of the ampoules, ensuring that each ampoule slides onto the top of the rotating plate 52 in a uniform posture, avoiding confusion that could affect subsequent clamping. A feed inlet 59 is fixedly connected to the right side of the support column 4, providing an entry point for the operator to insert the ampoules. The size of the opening is adapted to the size of the ampoules, facilitating batch insertion and guiding the ampoules to accurately enter the interior of the support column 4, preventing them from falling during insertion. The external rotating plate 52 is rotatably connected to the interior of the support column 4, with the top of the rotating plate 52 contacting the bottom of the feed baffle 57. The bottom of the fixed shaft 54 ​​is rotatably connected to the top of the rotating plate 52, and the bottom of the arc plate 55 is in contact with the top of the rotating plate 52.

[0016] Working principle: After the feeding mechanism 5 is started, motor 2 51 drives the rotating plate 52 to rotate at a constant speed inside the support column 4. The operator puts the ampoules to be filled into the support column 4 through the feed port 59. The ampoules slide down along the inclined angle of the feed baffle 57 and finally fall to the top of the rotating plate 52. As the rotating plate 52 rotates, the ampoules are brought to the bottom of the arc plate 55. The arc plate 55 is fixed inside the support frame 53 by the fixed shaft 54. Its arc structure provides lateral restraint for the ampoules on the rotating plate 52, preventing the ampoules from tipping over or shifting during rotation. At the same time, the limiting plate 58 cooperates with the feed baffle 57 to restrict the movement trajectory of the ampoules, ensuring that each ampoule is conveyed to the discharge position on the right side of the support column 4 in a uniform posture by the rotating plate 52. When the ampoule is transported from the support column 4 to the support base 2, the adjusting clamping mechanism 3 starts to work. The telescopic springs 35 in the two fixed boxes 31 will automatically adjust the telescopic amount according to the actual diameter of the ampoule, which will push the two moving frames 36 to move in opposite directions. The moving frames 36 drive the sliding square column 33 and the moving plate 34 at the bottom to slide on the inner wall of the fixed box 31. At this time, the telescopic springs 35 are compressed and generate a reverse elastic force. Finally, the two moving frames 36 stabilize the ampoule in the middle position through this adaptive adjustment, ensuring that the ampoule will not shake or shift during the filling process. After the ampoule is clamped and positioned, the drive assembly 37 is activated to help maintain the filling posture. Motor 38 drives the rotating rod 39 to rotate inside the moving frame 36. The fixed sleeve 32 outside the rotating rod 39 rotates accordingly, contacting the outer wall of the ampoule. Its rotation direction is opposite to the potential displacement of the ampoule during filling, further limiting positional changes through friction. Simultaneously, the rotating plate 52 continues to rotate, maintaining contact with the bottom of the arc-shaped plate 55, ensuring that subsequent ampoules can be continuously and orderly conveyed to the clamping area, achieving a seamless operation of feeding, clamping, and filling.
