Cylinder 2 uses high-performance hydraulic or pneumatic components, which can generate enough pressure to drive rack 10 to move back and forth. Its internal structure is precise, with good sealing performance, which can ensure long-term stable operation with low maintenance cost. Bidirectional connecting plate 4 plays a key role in connecting cylinder 2 and rack 10. One end of bidirectional connecting plate 4 is fixed on connecting head 3 on cylinder 2 through threaded connection or other reliable connection methods, and the other end is connected with rack 10. The material and structure design of bidirectional connecting plate 4 make it have good strength and toughness, which can withstand large tension and pressure during power transmission, ensuring the normal operation of the device.

The shape and size of connecting head 3 match the connecting end of bidirectional connecting plate 4, which can realize stable connection and power transmission through precise machining and cooperation. Its surface is hardened, with high hardness and wear resistance, which can effectively reduce wear and prolong service life. Rack 10 is engaged with gear assembly 22, which drives gear assembly 22 to rotate by moving in side window 5. The tooth shape of rack 10 is precise, and the surface is precisely machined and heat treated, with good meshing performance and wear resistance. Its length and width are designed according to the actual capping stroke and device size, which can meet the capping needs of different specifications of containers. Side window 5 is set on side fixing plate 6, providing space for the movement of rack 10. The shape and size of side window 5 match the outer shape of rack 10, which can ensure smooth movement of rack 10. Its edge is chamfered to avoid scratching and damaging rack 10, which also helps to reduce noise and vibration. Gear assembly 22 is the core transmission component of the device, composed of multiple gears, which realizes power transmission and conversion through mutual engagement. The material of gear assembly 22 is usually high-quality alloy steel, which is precisely machined and heat treated, with high strength, high precision and good wear resistance.The modulus and number of teeth of the gear are designed according to the cap screwing torque and rotational speed requirements, which can realize precise cap screwing operation. The cap screwing end cover 8 is connected with the gear assembly 22 and is driven to rotate by the gear assembly 22 to realize the tightening or loosening operation of the container cap. The shape and size of the cap screwing end cover 8 are designed according to the specifications of the container cap, which is usually circular or square structure, and the inner side is provided with threads or clamping grooves matched with the container cap, which can firmly clamp the container cap. The material of the cap screwing end cover 8 is usually stainless steel or aluminum alloy, which has good corrosion resistance and lightweight characteristics, and can adapt to the cap screwing requirements of various liquid and solid containers. When the cap screwing operation is needed, the pressure cylinder 2 starts to work under the drive of the external control signal, generates pressure and transmits it to the double-way connecting plate 4 through the connecting head 3.

The material and structural design of the upper fixed plate 7 matches that of the base 12, with sufficient strength and rigidity to provide reliable support for the first fixed shaft 14. The second fixed shaft 20 also adopts a double fixing mode, with one end fixedly connected to the base 12 and the other end fixedly connected to the upper fixed plate 7. This structural design not only improves the stability of the second fixed shaft 20, but also effectively reduces the vibration and noise of the device, improving the smoothness of the device operation. The third fixed shaft 16 is fixedly connected to the base 12 at one end and to the upper fixed plate 7 at the other end. Through this double fixing mode, the third fixed shaft 16 can remain stable during the operation of the device, ensuring the normal rotation and transmission accuracy of the third gear 17. The rack 10 is driven by the pressure cylinder 2 to move, and the rack 10 drives the first gear 15 to rotate. The rotation of the first gear 15 is transmitted to the fourth gear 21 through gear meshing, and the fourth gear 21 is fixed on the second fixed shaft 20, thereby driving the second gear 19 to rotate. The rotation of the second gear 19 is further transmitted to the third gear 17, and the third gear 17 is fixed on the third fixed shaft 16, driving the third fixed shaft 16 to rotate. The rotation of the third fixed shaft 16 finally drives the capping end cover 8 to perform the capping operation, realizing the tightening or loosening of the container cover.

The rotation of the fourth gear 21 is transmitted to the second gear 19, so that it also rotates, ensuring smooth conduction of power from the pressure cylinder 2 to the capping end cover 8.

[0027] The third fixed shaft 16 is ingeniously installed with a third gear 17. In this transmission link, the second gear 19 drives the third gear 17 engaged with it to rotate synchronously. The rotation of the third gear 17 further drives the third fixed shaft 16 to rotate, accurately transmitting power to the cap screwing end cover 8, which can maintain high adaptability and reliability regardless of the size or shape of the container cap. The cap screwing end cover 8 is designed with an adapter hole at its upper end, and the cap screwing end cover 8 is replaceable. Users do not need to make large-scale adjustments or replacements to the entire device. They can easily replace the cap screwing end cover 8 of the corresponding specification according to specific needs, so that it can cope with various cap screwing tasks.
