[0021] As Figures 1-3 shown, a capping mechanism for an oral liquid capping machine includes a bottom plate 1 and a base 2 fixedly connected to the upper surface of the bottom plate 1. A conveying device 3 is arranged on the upper surface of the base 2. A support arm 4 is fixedly connected to the rear side position of the upper surface of the base 2. A lifting mechanism 5 is arranged inside the support arm 4 and extends to the upper surface. A base plate 6 is arranged on the front surface of the support arm 4. A capping head 7 is arranged inside the base plate 6 and extends to the lower surface. A positioning mechanism 8 is arranged inside and outside the base plate 6. The number of the conveying devices 3 is two. The transmission of the conveying device 3 is driven by its own motor. The lifting mechanism 5 includes a driving motor 51 fixedly connected to the upper surface of the support arm 4. The output end of the driving motor 51 is fixedly connected to a first lead screw 52. The outer circumferential surface of the first lead screw 52 is threadedly connected to a first nut seat 53. The outer surface of the first nut seat 53 is fixedly connected to the rear surface of the base plate 6. The positioning mechanism 8 includes limiting sliding grooves 81 opened on the upper and lower surfaces of the base plate 6. A linkage rod 82 is slidably connected inside the limiting sliding grooves 81. An electric telescopic rod 83 is fixedly connected to the middle position of the upper surface of the base plate 6. The linkage rod 82 is rotatably connected to the upper end of the electric telescopic rod 83. A clamping plate 84 is arranged at the lower end of the linkage rod 82. A disassembly mechanism 85 is arranged between the linkage rod 82 and the clamping plate 84. A rotating shaft is fixedly connected to the middle section of the linkage rod 82 so that the linkage rod 82 can rotate. The rotating shaft can only be horizontally limited and slid inside the limiting sliding grooves 81. The disassembly mechanism 85 includes a plugging seat 851 fixedly connected to the lower end of the linkage rod 82. An inserting block 852 is fixedly connected to the outer surface of the clamping plate 84. The outer surface of the plugging seat 851 extends to the inner surface and is threadedly connected to a locking screw 853.

[0022] By adopting the above technical solution, the conveying device 3 of this device is docked on the liquid bottle conveying device. The two conveying devices 3 can perform handover and transmission of the liquid bottles. When the liquid bottles are transmitted to the lower part of the base plate 6, the driving motor 51 can drive the first lead screw 52 to rotate, driving the first nut seat 53 and the base plate 6 to lift and lower. After lowering, the capping head 7 can perform the capping operation. Before capping, the positioning mechanism 8 can perform the positioning operation. The electric telescopic rod 83 can extend, driving the clamping plate 84 at the lower end of the linkage rod 82 to perform pre-positioning on the liquid bottle.

[0023] As Figure 4 shown, a bidirectional lead screw 9 is rotatably connected to the inner surface of the base 2, and a hand wheel is fixedly connected to the front end of the bidirectional lead screw 9.

[0024] Further, a second nut seat 10 is threadedly connected to the outer cylindrical surface of the bidirectional lead screw 9, and the second nut seat 10 is fixedly connected to the lower surface of the conveying device 3. A preset sliding groove is formed in the upper surface of the base 2, and a connecting rod between the second nut seat 10 and the conveying device 3 is limited and slidably connected inside the preset sliding groove.

[0025] Working principle: When using the capping mechanism for an oral liquid capping machine, first, the conveying device 3 of this device is docked on the liquid bottle conveying device. The two conveying devices 3 can perform handover and transmission of the liquid bottles. When the liquid bottles are transmitted below the substrate 6, the driving motor 51 can drive the first lead screw 52 to rotate, driving the first nut seat 53 and the substrate 6 to move up and down. After descending, the capping head 7 can perform the capping operation. Before capping, the positioning mechanism 8 can perform the positioning operation. The electric telescopic rod 83 can extend, driving the clamping plate 84 at the lower end of the linkage rod 82 to perform pre-positioning on the liquid bottle. If it is necessary to replace the clamping plate 84, the locking screw 853 can be unscrewed, and the insert block 852 can be taken out of the socket 851. By rotating the bidirectional lead screw 9 through the handwheel, the two nut seats 10 can be controlled to approach or move away from each other, thereby adjusting the distance between the two conveying devices 3. This is the working principle of the capping mechanism for the oral liquid capping machine.
