The rotating main shaft 2-4 and the ball spline 1-14 are fixedly connected to the coupling 1-15 by a key connection, so that the rotational power below can be transmitted to the timing pulley 2-19 above. The lifting main shaft 2-3 passes through two oil-free bushings 1-2-5 from bottom to top, which slide relative to the bottle head support 2-1. The inner side of the top shaft is fitted with a rotating bearing 2-16. The top protruding step is connected to the upper part of the corrugated sleeve 2-6 by a flange. The top protruding step is connected to the lower part of the capping head pad 2-14. When the lower lifting motor is working, the lifting power is transmitted to the upper component through the screw connecting plate 1-19, which drives the upper whole to lift. The bottle head support 2-1 is an external support. Its bottom is fixedly connected to the lower oil-free bushing cap 2-10, locking and limiting the oil-free bushing 12-5. The upper step is fixedly connected to the table, and a sealing groove is provided at the step, with an O-ring inside for sealing. The top has stepped grooves on both the inside and outside.

The two of them fix and press the flange below the corrugated sleeve 2-6 and the cap lifting silicone gasket 2-9 tightly. The cap lifting silicone gasket 2-9 acts as a sealing element, which can isolate the environment above and below the table.The capping head pad 2-14 serves as a connecting component between the upper and lower parts. The perpendicularity between the lifting shaft and the connecting plate can be controlled by the flatness machining accuracy of the upper and lower connecting surfaces, effectively reducing the machining difficulty of the lifting shaft and the connecting plate. Its lower inner side is positioned in conjunction with the top step of the lifting shaft and then fixedly connected by bolts. An O-ring is provided between the two for sealing. Its upper part is positioned in conjunction with the protruding step of the bottle pressing head mounting plate 2-15 and then fixedly connected by bolts. An O-ring is provided between the two for sealing. Above the bottle-pressing head mounting plate 2-15 is the installation position for power transmission. Five bottle-pressing structures 2-18 are arranged in a row and fixed to the front end of the mounting plate with bolts. Two tensioning wheel assemblies 2-21 are symmetrically arranged with the middle bottle-pressing structure 2-18 as the center of symmetry. This provides sufficient angle for the synchronous belt 2-22 to wrap around another synchronous pulley 2-19 on top of the bottle-pressing structure 2-18. The inner toothed side of the synchronous belt 2-22 engages with the grooves of the synchronous pulley 2-19 and the synchronous pulley on top of the bottle-pressing structure. The back of the belt wraps around the tensioning wheel assembly 2-21 and the adjustable tensioning assembly 2-20. After a large number of batches of operation, the synchronous belt 2-22 will gradually loosen. The adjustable tensioning assembly can be adjusted outwards, and the synchronous belt will continue to maintain tension to prevent the synchronous belt teeth from dislodging. The bottle-pressing structure 2-18 can be a quick-change type to accommodate containers of different sizes.

[0054] like Figure 11-16As shown, the capping knife holder swing servo motor assembly 4-2 provides rotational swing power for the capping knife holder. Its upper mounting flange is fixedly installed after being aligned with the holes below the lower connecting plate 4-4 of the capping knife motor. The upper connecting plate 4-3 of the capping knife motor and the lower connecting plate 4-4 of the capping knife motor are fixedly connected at the four corners by four capping knife motor support columns 4-6. The upper part of the upper connecting plate 4-3 of the capping knife motor is fixedly connected to the table, so that the power assembly is fixed under the table. The drive shaft 4-7 passes through the middle hole of the connecting plate 4-3 on the capping knife motor and is connected to the connecting shaft of the capping knife holder swing servo motor assembly 4-2 via the capping knife motor coupling 4-5. Two bearings 4-9 are sequentially mounted on the drive shaft 4-7 from bottom to top. The outer ring of bearing 4-9 is engaged in the bearing groove below the bottle holder assembly support 4-8. The outer ring of the upper bearing 4-9 contacts the step of the inner groove of the support for limiting its movement, while the inner ring of the lower bearing 4-9 is limited by a retaining spring mounted on the drive shaft. A bearing 4-18 is installed on the upper drive shaft step, and its outer ring is engaged in the bottle holder assembly support 4-8. Inside the square bearing groove, the lower part of bearing 4-18 contacts and limits the step of the bottle holder assembly support 4-8, and the upper part contacts and limits the step of the tool holder drive shaft 4-7. A bottle holder assembly sealing ring 4-10 is installed on it. Two O-rings are installed at the contact position with the tool holder drive shaft 4-7 for sealing, and one O-ring is installed at the contact position with the bottle holder assembly support 4-8 for sealing. This can effectively isolate the external environment from the internal environment of the isolator. The lower part of the sealing ring mounting flange is fixedly connected to the support, and the upper part is fixedly connected to the bottle holder assembly housing support plate 4-11. The top of the drive shaft is fixedly connected to the fixed end of the power swing arm 4-16. The swing arm 4-16 has a high raised step at its swing end, which better guides and positions the upper combined support plate 4-24. Two bearings 4-20 are located at the top and bottom of the swing end, respectively. The outer ring of bearing 4-20 is inserted into the bearing groove of the swing end, and the inner ring is fitted under the support plate connecting shaft. A tool holder spacer 4-23 is placed between the two bearings 4-20 to fix and limit the inner ring of the bearing 4-20. Bolts are located at the bottom of the support plate connecting shaft to block and limit the lower bearing 4-20, while the upper bearing 4-20 is limited by contacting the step below the support plate connecting shaft. The combined support plate 4-24 consists of two guide connecting shafts and a connecting plate. Three mounting slots are located in the middle of the connecting plate, with through holes on both sides. Threaded holes are provided at corresponding positions on the connecting shafts. The connecting plate and connecting shafts are fixedly connected by bolts. Considering that the upper and lower positions of the connecting shafts need to connect with other components, the mating positions of this part need to be adjusted after assembly. This combined part can be considered as a single unit.The upper connection of the combined support plate 4-24 is fitted into the mounting hole of the capping knife holder 4-25. The two fit tightly together, ensuring accurate positioning of the capping knife. The locking knob 4-26 is inserted into the knife holder from top to bottom to fix the knife holder and the connecting plate, preventing the capping knife holder from loosening and falling off. The capping knife holder 4-25 has a threaded hole at the front, which is locked and fixed by the cap and nut on the capping knife 4-27. One end of the lower connection of the combined support plate 4-24 is connected to the swing end of the power swing arm 4-16, and the other end is connected to the swing end of the follower swing arm 4-17. The swing end of the follower swing arm 4-17 has the same structure as the swing end of the power swing arm 4-16. Bearings 4-21 are installed at the upper and lower positions inside, and the middle position is limited by the tool holder spacer 4-23. There are two bearing slots in the fixed end of the follower swing arm 4-17, and bearings 4-19 are installed in them. A follower spacer 4-22 is installed between the two bearings 4-19 for limitation. The upper bearing 4-19 is limited by a retaining spring installed on the follower support seat 4-15, and the lower bearing 4-19 is limited by contact with the step of the follower support seat 4-15. The follower support seat 4-15 is fixedly installed on the bottle holder assembly box support plate 4-11 through the bottom through hole. The bottle holder assembly housing support plate 4-11 also has a support installation position between the mounting holes of the power swing arm 4-16 and the follower swing arm 4-17. A bottle holder assembly sealing ring 4-10 is fixedly connected below it, and a bottle holder assembly support 4-8 is fixedly connected below the sealing ring. The two supports can make the entire housing more stable. A waterproof connector 4-14 is fixedly connected inside the sealing ring. This connector is used to provide an air source connection position for the cylinder assembly inside the housing. A bottle holder assembly housing 4-12 is fixedly connected above the bottle holder assembly housing support plate 4-11. The housing has a mounting plate in the middle for mounting the bottle holder assembly cylinder. The rear center, front sides, and front of the housing contact the bottle holder assembly housing support plate 4-11. The rear two sides are open at the angles to provide swing space for the follower swing arm 4-17 and the power swing arm 4-16. The front of the bottle holder assembly housing 4-12 is open, and a bottle holder housing cover plate 4-13 is bolted onto it. The cover plate can be opened during installation and debugging to facilitate internal installation and debugging operations. A bottle holder assembly support plate 4-1 is fixedly connected above the bottle holder assembly housing 4-12, and the bottle holder assembly mounting base can be fixedly mounted on the support plate. The overall structure is stably fixed to the tabletop by two supports. When the motor below provides rotational power, the power is transmitted to the power swing arm through the drive shaft. As the power swing arm swings, the auxiliary connecting plate of the follower swing arm stably drives the capping knife holder to swing closer to the container. When the capping knife contacts the aluminum cap, it slowly swings to complete the capping action. After capping is completed, it swings in the opposite direction, and the overall structure resets to start the next round of capping. The capping knife 4-27 can be a spring-loaded capping knife with a spring-loaded structure to prevent the bottle mouth from breaking after capping.

[0055] like Figure 19-21As shown, cylinder 3-1, located at the bottom of the assembly, provides lifting power to the upper structure. A cylinder shaft 3-2 is fixedly connected to it. A bearing 3-3 is installed in the outer stepped groove at the top of cylinder shaft 3-2. The outer ring of bearing 3-3 is limited by a retaining ring mounted on bottle holder shaft bushing 3-8, and the inner ring is limited by a bolt head mounted on the cylinder shaft. A mounting hole for the inner shaft 3-7 of the bottle holder is located in the middle of the upper part of the bottle holder shaft bushing 3-8. The inner shaft 3-7 is inserted into this mounting hole, and the inserted part of the shaft has a groove that mates with the set screw hole on the side of the bottle holder shaft bushing 3-8. The connection is secured by the side set screw. A keyway is provided in the middle of the inner shaft 3-7 of the bottle holder, which is connected to the outer shaft of the bottle holder by a key. This key can restrict the left and right directions of the inner and outer shafts, allowing them to rotate in the same direction. Two bearings 11 3-5 are respectively provided at the upper and lower positions on the outer side of the outer shaft of the bottle holder. The outer ring of the bearing 11 3-5 is fitted inside the bottle holder fixing seat 3-6. Below the bottle holder fixing seat 3-6 is a friction pad 3-4. The bottle holder fixing seat 3-6 is installed above the bottle holder assembly support plate 4-1, and the friction pad 3-4 is installed below the bottle holder assembly support plate 4-1. The bottom of the bottle holder 3-9 is inserted into the top of the inner shaft 3-7 of the bottle holder. Ball-head plungers are provided on both sides of the inner shaft groove, which cooperate with the grooves of the bottle holder inlet and outlet parts for positioning. When the downward pressure on the bottle holder is greater than the supporting force provided by the cylinder, the bottle holder drives the inner shaft and bearing sleeve to press down; when the bottle holder rotates, the inner shaft drives the outer shaft to rotate; when the downward pressure on the bottle holder decreases, the cylinder drives the bearing sleeve, inner shaft and bottle holder to rise. When the bearing sleeve contacts the friction plate, the friction increases, which can effectively and timely stop the rotation.
