A hydraulic cylinder 9 is provided on the upper surface of the top plate 7. The piston rod of the hydraulic cylinder 9 passes through the top plate 7 and is connected to the lifting plate 10. A guide sleeve 26 is provided at each of the four corners of the lifting plate 10. The lifting plate 10 is guided and engaged with the support guide column 6 through the guide sleeve 26 to ensure the stability of the lifting plate 10. A number of sleeves 11 are provided on the lifting plate 10.

[0026] The conveying mechanism includes a drive roller 12, a driven roller 13, a conveyor belt 15, and multiple support rollers 14. The drive roller 12, driven roller 13, and support rollers 14 are rotatably mounted between two side frames 1. The support rollers 14 are mounted between the drive roller 12 and the driven roller 13. The tops of the drive roller 12, driven roller 13, and support rollers 14 are at the same horizontal height, i.e., tangent to the same horizontal straight line, to ensure the flatness of the upper part of the conveyor belt 15, thereby ensuring the stability when the bottles move. The drive roller 12 and driven roller 13 are connected to both ends of the conveyor belt 15. The conveyor belt 15 is supported on the support rollers 14. A reduction motor 22 is mounted on the outer surface of one of the side frames 1. The output shaft of the reduction motor 22 is connected to one end of the drive roller 12. The reduction motor 22 drives the drive roller 12 to rotate, thereby realizing the rotation of the conveyor belt 15.

[0027] The capping mechanism includes a servo motor 16, a main shaft 17, and a rubber rotating disk 18. The servo motors 16 are arranged in two rows and symmetrically on the upper surface of the lifting plate 10. The positions of the two rows of servo motors 16 correspond one-to-one. The top plate 7 has through slots 25 at each servo motor 16 to ensure that the servo motors 16 do not collide with the top plate 7 when the lifting plate 10 is raised or lowered. The output shaft of any servo motor 16 passes through the lifting plate 10 and is connected to the main shaft 17. Each main shaft 17 has a rubber rotating disk 18 at its bottom. The rubber rotating disk 18 is coaxially provided with a connecting sleeve 24. The connecting sleeve 24 is fitted with the main shaft 17 and fastened by radial locking bolts. This allows the rubber rotating disk 18 to be replaced according to the installation requirements of bottle caps of different sizes, improving applicability.

[0028] The pressure plate mechanism includes a pressure plate 19 and columns 20. The pressure plate 19 is located below the lifting plate 10. Several columns 20 are provided on the upper surface of the pressure plate 19. The columns 20 correspond one-to-one with the sleeves 11 in the lifting plate 10 and are fastened together by locking bolts. The pressure plate 19 is located between two rows of servo motors 16. One end of the pressure plate 19 is provided with an oblique transition section 21.

[0029] Installation method and operating principle: First, install the drive roller 12, driven roller 13, and support roller 14 between the two side frames 1. During installation, connect both ends of the conveyor belt 15 to the drive roller 12 and driven roller 13. The upper part of the conveyor belt 15 is supported on the support roller 14. Next, install the reduction motor 22 on the outside of one corresponding side frame 1, and connect the output shaft of the reduction motor 22 to one end of the drive roller 12. The conveyor motor can drive the drive roller 12 to rotate, thereby driving the conveyor belt 15 to rotate. Connect the pressure plate 19 to the sleeve 11 in the lifting plate 10 through the upright. The side wall of the sleeve 11 is fastened to the upright through locking bolts, so that the pressure plate 19 is located below the lifting plate 10. Then, install two rows of servo motors 16 on the upper surface of the lifting plate 10. Using a single servo motor 16 can realize the control and adjustment of different position speeds, which is more adaptable than the traditional method of controlling multiple rotating disks by a single motor through gears or chains. Next, the support guide column 6 is installed on the upper surface of the side frame 1. Then, the lifting plate 10 is connected to the support guide column 6 through the guide sleeve 26. Subsequently, the top plate 7 is installed on the top of the support guide column 6, and the hydraulic cylinder 9 is installed on the upper surface of the top plate 7. At the same time, the piston rod of the hydraulic cylinder 9 is connected to the lifting plate 10. A suitable rubber rotating disk 18 is selected according to the model of the bottle cap and bottle body being processed, and the rubber rotating disk 18 is fastened to the main shaft 17 through the connecting sleeve 24 and the locking bolt. Finally, the cylinder 4 is installed on the outer surface of the upright plate 3, and the guide rod 23 of the limiting plate 5 is passed through the guide hole of the upright plate 3. At the same time, the piston rod of the cylinder 4 is connected to the limiting plate 5 to complete the installation. Before use, the distance between the two limiting plates 5 is controlled by the cylinder 4 to move the bottle to the middle position of the conveyor belt 15. According to the height of the bottle, the lifting plate 10 is raised and lowered by the hydraulic cylinder 9 to match the height of the rubber rotating disk 18 with the bottle cap. At the same time, the height of the upright 20 is adjusted and locked by the locking bolt to match the height of the pressure plate 19 with the height of the bottle cap. During operation, each servo motor 16 is started. The servo motor 16 drives the rubber rotating disk 18 to rotate at high speed through the main shaft 17. Using the existing automatic cap placement technology, the bottle cap is placed at the bottle mouth. The bottle is driven forward by the conveyor belt 15. When it moves to the inclined transition section 21 of the pressure plate 19, the bottle cap is pressed down and engages with the bottle mouth thread. Then the bottle cap passes between two rows of high-speed rubber rotating disks 18 rotating in the same direction. The outer periphery of the rubber rotating disk 18 performs capping on both sides of the bottle cap.This utility model has a reasonable structure. The lifting plate 10 is guided and cooperates with the support guide column 6 on the upper surface of the side frame 1. The lifting plate 10 is equipped with two rows of servo motors 16. The output shaft of the servo motor 16 is mounted with a rubber rotating disk 18 through the main shaft 17. The capping process is realized by the rubber rotating disks 18 on both sides. The height of the lifting plate 10 can be controlled by the hydraulic cylinder 9, which makes it easy to adjust according to the height of different bottles, greatly improving flexibility. Furthermore, the lifting plate 10 is connected to the column 20 of the pressure plate 19 through the sleeve 11. On the one hand, the pressure plate 19 with the inclined transition section 21 can press the bottle cap and the bottle mouth as tightly as possible, thus ensuring the subsequent capping process. This method is less costly than setting a separate capping device. On the other hand, the height of the pressure plate 19 can be adjusted by the cooperation of the column, sleeve 11 and locking bolt, thus making it suitable for capping bottle caps of different heights, further improving the applicability.
