[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-2 The utility model provides an embodiment of an automatic cap screwing structure, comprising a mounting plate 1, a limiting column 2 fixedly connected to the upper surface of the mounting plate 1, a column 3 fixedly connected to the upper surface of the mounting plate 1, a sliding ring 4 slidably connected to the side wall of the limiting column 2, a fixed frame 5 fixedly connected to the side wall of the sliding ring 4, a motor 6 fixedly connected to the side wall of the fixed frame 5, a worm 7 fixedly connected to the output end of the motor 6, a side plate 8 fixedly connected to the upper surface of the fixed frame 5, a rotating shaft 24 rotatably connected between the side plates 8, and a worm gear 9 fixedly connected to the side wall of the rotating shaft 24. The worm wheel 9 is meshed with the worm 7, the side wall of the rotating shaft 24 is fixedly connected to the gear 10, the side wall of the limiting column 2 is fixedly connected to the rack 11, the rack 11 is meshed with the gear 10, and a limiting assembly is provided on the side wall of the sliding ring 4, the side wall of the sliding ring 4 is fixedly connected to the fixed plate 13, the side wall of the fixed plate 13 is fixedly connected to the motor 2 14, the output end of the motor 2 14 is fixedly connected to the sleeve 15, the limiting assembly includes a limiting ring 12, the side wall of the limiting ring 12 is fixedly connected to the side wall of the sliding ring 4, and the inner side wall of the limiting ring 12 is slidably connected to the side wall of the column 3.

[0031] After the cosmetic bottle is secured, motor 1 (6) is activated, driving worm 7 to rotate. This rotation further drives worm gear 9. Simultaneously, shaft 24 rotates between side plates 8, which in turn drives gear 10, which in turn moves on rack 11. This movement further drives sliding ring 4 to slide along the sidewalls of retaining post 2. The sliding movement of sliding ring 4 changes the height of sleeve 15, thereby accommodating cosmetic bottles of varying heights. Once sleeve 15 is positioned on the exterior of the cosmetic bottle cap, motor 2 (14) is activated to rotate sleeve 15. The internal shape of sleeve 15 matches the bottle cap, and its inner wall is made of non-slip rubber. As sleeve 15 rotates, motor 1 (6) again drives worm 7, which, through worm gear 9, drives shaft 24, which in turn rotates gear 10. This in turn drives sliding ring 4 downward, causing sleeve 15 to rotate and move downward, allowing the cap to be twisted.

[0032] Reference Figure 3The upper surface of the mounting plate 1 is fixedly connected to a fixing seat 16, a slide groove 17 is opened inside the fixing seat 16, a placement rack 18 is fixedly connected to the upper surface of the fixing seat 16, a slider 19 is slidably connected inside the placement rack 18, the side wall of the slider 19 is slidably connected to the inside of the slide groove 17, the side wall of the slider 19 is fixedly connected to a rubber pad 23, the inside of the fixing seat 16 is fixedly connected to a motor three 20, the output end of the motor three 20 is fixedly connected to a turntable 21, the side wall of the turntable 21 is rotatably connected to a bent plate 22, one end of the bent plate 22 is rotatably connected to the side wall of the slider 19, and the sleeve 15 is arranged at the center directly above the fixing seat 16.

[0033] In order to ensure that the cosmetic bottle remains stable during the subsequent capping process, it is necessary to first fix the mounting plate 1. The mounting plate 1 is the foundation of the entire automatic capping structure. It connects the various components tightly together to ensure the smooth progress of the entire process. Next, the cosmetic bottle that needs to be capped is placed on top of the placement rack 18. After ensuring that the cosmetic bottle is stably placed, the motor 3 20 can be started. The function of the motor 3 20 is to drive the turntable 21 to rotate. As the motor 3 20 runs, the rotation of the turntable 21 will drive the curved plate 22 to move. During the rotation of the curved plate 22, one side of it will rotate on the turntable 21, and the other side will rotate on the slider 19 while pulling the slider 19 to move. During this process, the rubber pad 23 will cling to the side wall of the cosmetic bottle, playing a fixing role, ensuring that the cosmetic bottle will not be displaced during the capping process.

[0034] Working principle: when using this structure to automatically twist the lid of a cosmetic bottle, first fix the mounting plate 1, and then place the cosmetic bottle that needs to twist the lid on the top of the placement rack 18. At this time, the motor 3 20 is started to drive the turntable 21 to rotate, thereby driving the bent plate 22 to move. At this time, one side of the bent plate 22 will rotate on the turntable 21, and the other side will rotate on the slider 19, pulling the slider 19 to move, and making the rubber pad 23 fit on the side wall of the cosmetic bottle and fix it. After the fixation is completed, the motor 1 6 is started to drive the worm 7 to rotate, thereby making the worm gear 9 rotate and the rotating shaft 24 rotate between the side plates 8, thereby driving the gear 10 to rotate. When the gear 10 rotates, it will move on the rack 11, thereby driving the sliding ring 4 to slide on the side wall of the limit column 2, thereby changing the height of the sleeve 15. When the sleeve 15 is sleeved on the outside of the cosmetic bottle cap, the sleeve 15 can be driven to rotate by starting the motor 2 14 to perform automatic twisting of the lid.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
