Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a filling and capping machine. Background Technology

[0002] An automatic cap-removing cryopreservation tube filling machine with application number CN202222936330.4 employs two separate mechanisms for cap removal and cap screwing, resulting in a complex structure. The machine includes a cap screwing and filling machine with an electrical control box and a track platform arranged parallel to the machine. The track platform is equipped with a mold for placing packaging materials. Both the track platform and the cap screwing and filling machine are controlled and connected to the electrical control box. The cap is held in place by a gripper cylinder, which is directly exposed to the external environment; any gas leakage could cause contamination of the medication. Utility Model Content

[0003] The technical problems to be solved by this utility model are: the need for multiple capping heads in the process of removing and tightening the caps on packaging materials, which makes the overall structure complex, and the problem of leakage from the grippers causing contamination of the medicine.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] First, a filling and capping machine is provided, including a conveying module for conveying a bottle placement mold. The conveying module is provided with a filling module and a capping module along its conveying direction. The bottle placement mold is provided with bottle placement stations at intervals, and cap placement stations are provided between the bottle placement stations. The capping module includes a capping mechanism that can be raised and lowered.

[0006] The bottle mold is transported back and forth between the filling module and the capping module by the conveying module, so that the capping, filling and screwing operations are carried out. The overall structure is compact and has a wide range of applications.

[0007] Furthermore, the capping mechanism includes a sleeve, one end of which is fitted with a capping head, and the other end is provided with a drive shaft. A cylinder is provided inside the sleeve, and the working end of the cylinder extends into the capping head. The drive shaft is connected to a lifting motor and a capping motor.

[0008] The cylinder pushes out the cap that has been squeezed into the capping head, ensuring that the capping head will not lift the cap and bottle during the upward process, making the device more effective.

[0009] Furthermore, the capping module also includes a housing, inside which a transmission assembly is disposed, the transmission shaft is connected to the transmission assembly, and the transmission assembly is connected to the capping motor.

[0010] The transmission component, as an intermediate transmission component, ensures that the power of the motor can be smoothly transmitted to the capping head.

[0011] Furthermore, the lifting motor is connected to a lifting drive shaft, which is connected to the outer casing.

[0012] The extension and retraction of the lifting drive shaft can move the outer casing up and down.

[0013] Furthermore, the transmission assembly includes a drive shaft and a driven shaft. A drive synchronizing pulley is mounted on the drive shaft, and a driven synchronizing pulley is mounted on the driven shaft. The drive synchronizing pulley and the driven synchronizing pulley are connected by a timing belt. The capping motor is connected to the drive shaft, and a coaxially arranged transmission shaft passes through the end face of the driven shaft.

[0014] Furthermore, a torque limiter is installed between the drive shaft and the drive synchronizing pulley.

[0015] Using a torque limiter can prevent excessive torque from damaging the cap and bottle by the screw capping head, thus improving the safety and effectiveness of the device.

[0016] Furthermore, a spring is provided between the drive shaft and the driven shaft.

[0017] A spring is used to create a buffer space between the drive shaft and the driven shaft, preventing the capping head from crushing the cap and bottle, thus improving the safety of the device.

[0018] Furthermore, it also includes a work surface, on which a conveying module, a filling module, and a capping module are provided.

[0019] Furthermore, the filling module includes a filling pump, which is connected to a filling needle.

[0020] Furthermore, a weighing module is provided within the filling module.

[0021] This utility model has the following beneficial effects:

[0022] I. The overall structure of this invention is reasonable, which can reduce repetitive actions, thereby reducing the use of drive motors and their transmission structures. The structure is simple and more economical.

[0023] Second, the cylinder can effectively push out the tube cap, and since the cylinder is placed inside the sleeve, it will not contaminate the liquid medicine when the cylinder leaks gas, thus providing a certain degree of protection. Attached Figure Description

[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] It should be noted that all directional indicators in this embodiment are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] This utility model provides a filling and capping machine, such as Figure 1As shown, it includes a platform 70, on which a conveying module 20 is provided. A filling module 30 and a capping module 40 are sequentially arranged on the platform 70 along the conveying direction of the conveying module 20. A bottle placement mold 10 is transported on the conveying module 20. Bottle placement stations are provided at intervals on the bottle placement mold 10 to fix the bottles. Capping stations are provided between the bottle placement stations.

[0033] In this embodiment, the bottle and cap are screwed together during use. First, the bottle is placed on the bottle mold 10. Then, the conveying module 20 transports the bottle to the capping module 40. At this time, the capping module 40 unscrews the cap off the bottle. Then, the conveying module 20 transports the bottle with the cap off to the filling module 30 for filling. At the same time, the cap continues to be held by the capping module 40. This ensures that the inner wall of the cap remains in a sterile environment after it is unscrewed, which can effectively avoid the risk of cap contamination. After filling is completed, the conveying module 20 transports the bottle back to the capping module 40. Then, the capping module 40 screws the cap back on and transports it to the next process.

[0034] In other embodiments, there are cases where the bottle and the cap are separate, with the bottle placed in the bottle placement station and the cap placed in the cap placement station. In this case, the bottle is first filled, and the conveying module 20 transports the bottle placement mold 10 to the capping module 40. After the capping module 40 takes the cap, it screws the cap onto the corresponding bottle and then transports it to the next process.

[0035] like Figure 2 and Figure 3 As shown, the capping module 40 includes a housing 42, on which a drive shaft 61 and a driven shaft 62 are mounted. A capping head 41 is mounted on the driven shaft 62. A drive synchronous pulley 64 is mounted on the drive shaft 61, and a driven synchronous pulley 65 is mounted on the driven shaft 62. The drive synchronous pulley 64 and the driven synchronous pulley 65 are connected by a synchronous belt 63. A capping motor 60 is connected to the drive shaft 61. The capping motor 60 drives the drive shaft 61 to rotate, and then drives the driven shaft 62 to rotate through the drive synchronous pulley 64, the synchronous belt 63, and the driven synchronous pulley 65, thereby driving the capping head 41 to rotate. Rotating the capping head 41 can unscrew the cap, and rotating it in the opposite direction can screw the cap onto the bottle.

[0036] To prevent excessive torque from damaging the cap, a torque limiter 66 is installed between the drive shaft 61 and the drive timing pulley 64. When the torque is too high, the torque transmission can be stopped, which more effectively protects the cap and the bottle, making the device more stable, reliable, and effective.

[0037] Specifically, to make the capping process more stable and smooth, a coaxially arranged transmission shaft 67 is provided through the end face of the driven shaft 62. A sleeve 43 is installed on the end face of the transmission shaft 67, and a capping head 41 is installed at the end of the sleeve 43. In this embodiment, the driven shaft 62 and the transmission shaft 67 can be connected by a key, so that when the driven shaft 62 rotates, it drives the transmission shaft 67 to rotate. The rotation of the transmission shaft 67 drives the sleeve 43 to rotate, and the rotation of the sleeve 43 drives the capping head 41 to rotate, thus completing the capping operation.

[0038] Since the capping head 41 needs to move up and down during the capping process, in order to achieve the up and down movement of the capping head 41, in this embodiment, a lifting drive shaft 51 is connected to the outer shell 42. The extension and retraction of the lifting drive shaft 51 can drive the outer shell 42 to move up and down, thereby achieving the up and down movement of the capping head 41.

[0039] Specifically, the lifting drive shaft 51 is connected to the lifting motor 50, which provides power to extend and retract the lifting drive shaft 51. To make the overall structure more compact, the lifting drive shaft 51 is hollow inside, and the drive shaft 61 is coaxially arranged with the lifting drive shaft 51. Due to the error in bottle height during actual use, in order to ensure that the capping head 41 can adapt to different bottles, the driven shaft 62 and the transmission shaft 67 are connected by a spring 68. During the up and down movement of the capping head 41, the spring 68 has a certain buffer space. When the lifting drive shaft 51 extends or retracts excessively, it can still ensure that the capping head 41 can be stably fitted on the cap without crushing the bottle, making the device more effective.

[0040] In this embodiment, the capping head 41 is made of soft PU material and has an open bottom. During use, the capping head deforms when pressed down, holding the tube cap in place. At this time, the tube cap and the capping head 41 are in close contact. When the capping head 41 rotates, it can drive the tube cap to rotate and screw the tube cap onto the cryopreservation tube. When the capping head 41 rises, in order to prevent the tube cap and bottle from being lifted up together, a cylinder 44 is provided inside the sleeve 43. The working end of the cylinder 44 extends into the capping head 41. So before the capping head 41 rises, the cylinder 44 extends and pushes the tube cap out of the capping head 41, so that the tube cap and bottle are not lifted up when the capping head 41 rises.

[0041] Furthermore, the capping head 41 adopts a quick-release structure, which can be adapted to different tube caps by replacing different capping heads 41, making the device more widely used, and also facilitating the cleaning and sterilization of the tube capping head 41.

[0042] In this embodiment, the filling module 30 includes a filling pump 31, which is connected to a filling needle 32. The filling pump 31 provides power to deliver liquid through the filling needle 32 into the bottle. In order to ensure that the liquid weight in each bottle is consistent, a weighing module 33 is also provided in the filling module 30.

[0043] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of this utility model should be covered by the protection scope of this utility model.
