Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing equipment technology, and in particular to a fully automatic liquid filling and capping machine for pharmaceutical processing. Background Technology

[0002] Fully automatic liquid filling and capping machines are key equipment in modern pharmaceutical production lines. They can automatically complete a series of processes such as conveying, positioning, filling, capping and screwing on medicine bottles, which greatly improves production efficiency.

[0003] In a typical automated process, medicine bottles are usually transported by a continuously running conveyor belt to an intermittently rotating turntable. The turntable carries the medicine bottles sequentially through various functional stations. Ensuring that the medicine bottles on the conveyor belt are accurately and stably transferred to their designated stations on the turntable is the core factor determining the overall efficiency and reliability of the machine.

[0004] In some existing equipment, the operation of the conveyor belt and the rotation of the turntable are often controlled by independent drive systems. Sensors detect the position of the medicine bottles, and a central control system coordinates their start, stop, and speed. While this control method can achieve basic functions, its inherent delays, including sensor response delays, signal transmission delays, and control system processing delays, make it difficult to guarantee the synchronization accuracy between the conveyor belt and the turntable at high speeds. Accumulated small timing errors can cause medicine bottles to collide, tip over, or jam at the junction, resulting in bottle jamming, which interrupts production and affects product quality and equipment stability.

[0005] Therefore, this utility model proposes a fully automatic liquid filling and capping machine for pharmaceutical processing to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of poor bottle supply and inaccurate positioning caused by the mismatch between the bottle feeding mechanism and the rotary table station transmission in the existing fully automatic liquid filling and capping machine for pharmaceutical processing, this utility model aims to provide a fully automatic liquid filling and capping machine for pharmaceutical processing with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a fully automatic liquid filling and capping machine for pharmaceutical processing, including: a worktable, a conveyor belt, a turntable, a cap conveyor, a linkage motor, a rotating shaft; and a bevel gear set one, a rotating shaft, a driving sprocket, a driven sprocket, a transmission chain, a bevel gear set two, a connecting column, and a stop wheel.

[0008] The linkage motor drives the turntable and the resistance wheel to rotate synchronously in a purely mechanical manner through the rotating shaft.

[0009] Furthermore, the mechanical linkage structure is specifically manifested as follows: one end of the rotating shaft is fixedly connected to the output end of the linkage motor; a bevel gear at the bottom of the first bevel gear set is fixedly connected to the rotating shaft, a bevel gear at the top of the first bevel gear set is fixedly connected to the bottom of the rotating shaft, the top of the rotating shaft passes through the worktable and is fixedly connected to the bottom of the turntable, forming the first transmission path; simultaneously, a drive sprocket is also fixedly connected to the rotating shaft, the drive sprocket is connected to the driven sprocket through the transmission chain, the driven sprocket is coaxially fixedly connected to the bevel gear at the bottom of the second bevel gear set, the bevel gear at the top of the second bevel gear set is fixedly connected to the bottom of the connecting column, the top of the connecting column passes through the worktable and is fixedly connected to the stop wheel, forming the second transmission path.

[0010] Preferably, the fully automatic liquid filling and capping machine for pharmaceutical processing further includes a mechanical linkage device for driving the capping mechanism to lift and lower. This device includes a main sprocket fixed on the rotating shaft, a driven sprocket, a chain connecting the main sprocket and the driven sprocket, a cam fixedly connected to the driven sprocket on the same axis, a slider slidably embedded inside the cam, a push rod fixedly connected to the slider, and a bracket fixed to the top of the push rod.

[0011] Preferably, a capping motor is mounted on the bracket, the output end of the capping motor is connected to a connecting rod, the other end of the connecting rod is fixed to a housing, and the bottom of the housing is adjustablely fitted with a clamp for holding the bottle cap. This structure together constitutes a capping actuator that moves up and down with the bracket.

[0012] Preferably, in order to achieve the adjustable function of the clamp, a push plate is rotatably installed inside the housing, and the push plate is provided with a sliding groove. The clamp is slidably connected to the sliding groove of the push plate through a sliding rod. A rotating plate is fixed to the outside of the push plate. A bolt is provided on the housing. The bolt passes through the wall thickness of the housing and abuts against the rotating plate. By rotating the rotating plate, the push plate can be rotated, thereby changing the spacing of the clamp.

[0013] Preferably, the fully automatic liquid filling and capping machine for pharmaceutical processing further includes a spring sleeved on the outside of the connecting rod, with both ends of the spring fixed to the bracket and a fixing ring fixed to the outside of the connecting rod, for providing buffering and stable downward pressure during the capping process.

[0014] Preferably, in order to achieve rhythmic release of medicine bottles, the stop roller has a non-circular outer circumferential contour, with the protruding part on the contour used to block the medicine bottle and the concave part used to release the medicine bottle.

[0015] Preferably, in order to export the capped medicine bottles, the fully automatic liquid filling and capping machine for pharmaceutical processing also includes an output belt installed on the top of the workbench and adjacent to the turntable, and a push plate is rotatably installed on the side of the turntable near the output belt.

[0016] Preferably, when the medicine bottle is conveyed on the turntable, it passes through the output end of the cap conveyor to be fitted with a cap, in preparation for the subsequent capping process.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting up a linkage motor and driving the turntable and the stop wheel separately through two independent mechanical transmission chains via the same rotating shaft, the problems of mismatched rhythm, inaccurate bottle positioning or bottle jamming caused by independent driving or imprecise control between the conveyor belt bottle entry and the turntable station rotation in the prior art are solved. The precise synchronization of the stop wheel release and the turntable receiving action is achieved, which significantly improves the stability of the bottle supply and the overall operating efficiency of the machine.

[0018] 2. In this utility model, by setting a cam-slider mechanism driven by a power branch from the main transmission system, the lifting and lowering of the capping mechanism is controlled by mechanical linkage. This solves the problem that traditional capping machines need to set up an independent lifting drive device and a complex synchronous control system. It achieves the technical effects of simplifying the equipment structure, reducing manufacturing costs and failure rate, and ensuring precise coordination between the capping action and the turntable station switching.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a fully automatic liquid filling and capping machine for pharmaceutical processing, which aims to solve the structural problems in the prior art that cause poor supply and inaccurate positioning of medicine bottles due to transmission mismatch between the conveying mechanism and the station turntable.

[0023] like Figure 1 As shown, the fully automatic liquid filling and capping machine for pharmaceutical processing includes a worktable 1, which serves as the mounting base for the entire machine and supports various working components. A conveyor belt 28, a turntable 29, a bottle cap conveyor 30, and an output belt 31 are installed on the top of the worktable 1. The conveyor belt 28 is used to continuously transport medicine bottles 33. A linkage motor 2 is installed at the bottom of the worktable 1, which provides a unified power source for the entire machine.

[0024] The core transmission structure of the machine starts with the linkage motor 2. The output end of the linkage motor 2 is fixedly connected to the rotating shaft 3. The rotating shaft 3 serves as the main shaft for power distribution. The bevel gear at the bottom of the bevel gear set 4, the drive sprocket 7, and the main sprocket 6 are fixedly connected to it, thereby dividing the power into at least three paths. Two of these paths drive the turntable 29 and the resist wheel 27 to rotate synchronously through mechanical linkage.

[0025] The first power source is used to drive the turntable 29 to rotate. Specifically, the rotating shaft 3 is driven by the bevel gear at the bottom of the bevel gear set 4 fixed on it, which meshes with the bevel gear at the top of the bevel gear set 4. The bevel gear at the top of the bevel gear set 4 is fixedly connected to the bottom of the rotating shaft 5. The top of the rotating shaft 5 passes through the worktable 1 and is fixedly connected to the bottom of the turntable 29, thereby realizing the drive of the motor 2 to the turntable 29. The turntable 29 is used to receive, position and transport the medicine bottle 33.

[0026] The second power source is used to drive the rotation of the stop wheel 27, which is mechanically synchronized with the rotation of the turntable 29. Specifically, the rotating shaft 3 is connected to the driven sprocket 24 via the drive sprocket 7 fixed on it and the transmission chain 23. The driven sprocket 24 is rotatably mounted on the bottom of the workbench 1. The driven sprocket 24 is coaxially and fixedly connected to the bevel gear at the bottom of the bevel gear set 25. The bevel gear at the bottom of the bevel gear set 25 meshes with the bevel gear at the top of the bevel gear set 25. The bevel gear at the top of the bevel gear set 25 is fixedly connected to the bottom of the connecting column 26. The top of the connecting column 26 passes through the workbench 1 and is fixed with the stop wheel 27.

[0027] With the above structure, the rotation of the baffle wheel 27 and the rotation of the turntable 29 both originate from the power output of the same rotating shaft 3. The transmission ratio of the two transmission chains is fixed, thereby ensuring that the rotation rhythm of the baffle wheel 27 and the station switching rhythm of the turntable 29 are strictly synchronized. The baffle wheel 27 is located on one side of the conveyor belt 28 and adjacent to the turntable 29. It is used to rhythmically block and release the medicine bottles 33 conveyed by the conveyor belt 28, ensuring that the medicine bottles 33 can enter the positioning station of the turntable 29 one by one in an orderly manner. When the medicine bottles 33 are conveyed on the turntable 29, they pass through the output end of the bottle cap conveyor 30 to be loaded with bottle caps.

[0028] To achieve the automatic capping function of the medicine bottle 33, the fully automatic liquid filling and capping machine for pharmaceutical processing also includes a follow-up capping mechanism. This capping mechanism is linked with the rotation of the turntable 29 so that the capping action is completed when the medicine bottle 33 rotates with the turntable 29.

[0029] Please refer to the following carefully. Figure 1 and Figure 3 The transmission and lifting structure of this capping mechanism will be described in detail below: The power of this mechanism also comes from the rotating shaft 3, on which the main sprocket 6 is fixed. The main sprocket 6 is connected to the driven sprocket 9 via the chain 8. The driven sprocket 9 is rotatably mounted on the bottom of the workbench 1. The driven sprocket 9 is coaxially fixedly connected to the cam 10, which is used to convert the rotational motion into reciprocating linear motion. A slider 11 is slidably embedded inside the cam 10. The slider 11 is fixedly connected to the bottom of the push rod 12. The top of the push rod 12 passes through the workbench 1 and is fixedly connected to the bracket 13. When the cam 10 rotates with the driven sprocket 9, its internal irregular contour will drive the slider 11 to move up and down reciprocally, thereby driving the push rod 12 and the bracket 13 to achieve periodic lifting and lowering movements.

[0030] The bracket 13 serves as the mounting platform for the capping actuator. A capping motor 14 is mounted on the bracket. The output end of the capping motor 14 is connected to a connecting rod 16. The other end of the connecting rod 16 is fixed to a housing 17. A spring 15 is sleeved on the outside of the connecting rod 16. The two ends of the spring 15 are respectively fixed to the bracket 13 and a fixing ring fixed to the outside of the connecting rod 16. The spring 15 is used to provide downward pressure during capping and to act as a buffer.

[0031] With the above structure, when the turntable 29 rotates to one station, the cam 10 drives the bracket 13 to complete one lifting cycle, so that the capping actuator installed on the bracket 13 can accurately descend above the medicine bottle 33, complete the capping action, and then be lifted away to prepare for the arrival of the next medicine bottle.

[0032] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to accommodate bottle caps of different sizes, the clamp 22 of the capping actuator is designed with an adjustable structure; please refer to... Figure 3 and Figure 4 Inside the outer casing 17, a push plate 18 is rotatably mounted. The push plate 18 has a sliding groove. The clamp 22 is slidably connected to the sliding groove of the push plate 18 via a sliding rod 21. A rotating plate 19 is fixed to the outside of the push plate 18. A bolt 20 is provided on the outer casing 17. The bolt 20 passes through the wall thickness of the outer casing 17 and abuts against the rotating plate 19. By loosening the bolt 20, the rotating plate 19 can be rotated, thereby driving the push plate 18 to rotate, so that the sliding rod 21 slides in the sliding groove, thereby adjusting the distance between the clamps 22. After adjustment, the bolt 20 is tightened to lock the position.

[0033] As another preferred embodiment, in order to provide stable downward pressure and buffer protection during the capping process, a spring 15 is sleeved on the outside of the connecting rod 16. The two ends of the spring 15 are respectively fixed to the bracket 13 and a fixing ring fixed to the outside of the connecting rod 16. This structure allows the capping motor 14 to have a certain buffer displacement when encountering excessive resistance, preventing damage to the bottle cap or capping mechanism.

[0034] As another preferred embodiment, in order for the baffle wheel 27 to achieve clear blocking and releasing actions, the baffle wheel 27 has a non-circular outer peripheral profile. For example, its outer peripheral profile can be set as a star wheel-shaped structure with multiple concave arc surfaces and convex surfaces. By rotating, the convex surfaces block the medicine bottle 33, and the concave arc surfaces release the medicine bottle 33.

[0035] As another preferred embodiment, in order to automatically export the capped medicine bottle 33, an output belt 31 is also installed on the top of the workbench 1, and the output belt 31 is adjacent to the turntable 29; a push plate 32 is rotatably installed on the side of the turntable 29 near the output belt 31. When the medicine bottle 33 rotates with the turntable 29 to the output station, the push plate 32 is triggered to rotate, pushing the medicine bottle 33 from the turntable 29 onto the output belt 31.

[0036] Working principle: When started, the linkage motor 2 starts to work and transmits power through the rotating shaft 3.

[0037] On one hand, power drives the turntable 29 to rotate intermittently via bevel gear set 4 and rotating shaft 5. On the other hand, power drives the stop wheel 27 to rotate synchronously with the turntable 29 via drive sprocket 7, transmission chain 23, driven sprocket 24, bevel gear set 25, and connecting column 26. The medicine bottles 33 on the conveyor belt 28 continuously move towards the turntable 29, and are blocked and released in a rhythmic manner by the synchronously rotating stop wheel 27, ensuring that only one medicine bottle 33 is placed in the station of the turntable 29 each time when the turntable 29 is rotated to the correct receiving position.

[0038] As the turntable 29 rotates, the medicine bottle 33 passes through the filling station (not shown in the figure) and the cap mounting station in sequence. At the cap mounting station, the medicine bottle 33 passes under the cap conveyor 30 and is mounted with a cap.

[0039] Meanwhile, the power of the rotating shaft 3 also drives the cam 10 to rotate via the main sprocket 6, chain 8, and driven sprocket 9. The rotation of the cam 10, through the slider 11 and push rod 12, causes the bracket 13 and the entire capping actuator (including the capping motor 14, connecting rod 16, housing 17, clamp 22, etc.) mounted on it to perform a reciprocating up-and-down lifting motion. This lifting motion is strictly synchronized with the rotation of the turntable 29. When the medicine bottle 33 with the cap is mounted rotates to the capping station, the bracket 13 drives the capping actuator to descend, the clamp 22 covers the cap, the capping motor 14 starts and rotates, and drives the clamp 22 to tighten the cap through the connecting rod 16 and housing 17. After the capping is completed, the bracket 13 rises to make room for the next medicine bottle.

[0040] Finally, the capped medicine bottle 33 rotates with the turntable 29 to the output station, and the push plate 32 moves to push the medicine bottle 33 onto the output belt 31, completing the entire automated process.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
