[0038] The feeding mechanism is arranged on the base 1, and is used to sequentially feed a plurality of plastic bottles into a plurality of plug-in holes 5 with the bottle caps facing downwards. Figure 2 , the turntable 4 will sequentially deliver the multiple plug-in holes 5 thereon to the feeding mechanism during the rotation process;

[0039] The lifting mechanism is arranged on the turntable 4, and is used to hold the plastic bottle before the cover body is separated, and release the plastic bottle after the cover body is separated. The lifting mechanism includes an inner half ring 6, an outer half ring 7, a support leg 8 and a clamping assembly. An inner half ring 6 and an outer half ring 7 are arranged below the turntable 4, and a plurality of support legs 8 are fixedly connected to the inner half ring 6 and the outer half ring 7, respectively, and the plurality of support legs 8 are fixedly connected to the base 1. Figure 1 and Figure 3 , the inner half ring 6 and the outer half ring 7 are supported respectively by a plurality of supporting legs 8;

[0040] The clamping assembly is provided with a plurality of them, and each two mutually symmetrical clamping assemblies form a pair, and the plurality of pairs of the clamping assemblies are respectively arranged under the plurality of plug holes 5, and each of the clamping assemblies comprises a hanging plate 9, a supporting rod 10, a top rod 11, an arc-shaped supporting rod 12 and a first spring 13, the hanging plate 9 is fixedly connected to the turntable 4, and a plurality of supporting rods 10 are slidably connected to the hanging plate 9, one end of the plurality of supporting rods 10 are fixedly connected to the top rod 11, and the other end of the plurality of supporting rods 10 are fixedly connected to the arc-shaped supporting rod 12, such as Figure 4 The top rod 11 and the arc-shaped support 12 are supported by the support rod 10, and the arc-shaped support 12 is fixedly connected with a first spring 13, and one end of the first spring 13 away from the arc-shaped support 12 is fixedly connected to the hanging plate 9, such as Figure 4 , the first spring 13 applies a pulling force to the arc support 12 in the direction of the hanging plate 9; the two push rods 11 in each pair of the clamping assemblies respectively contact the inner half ring 6 and the outer half ring 7;

[0041] like Figure 3 and Figure 4, the two clamping assemblies in each pair are respectively located on both sides of the plug-in hole 5, and the clamping assemblies will rotate with the turntable 4. When a pair of clamping assemblies rotate to between the inner semi-ring 6 and the outer semi-ring 7 following the turntable 4, the two push rods 11 in the pair of clamping assemblies will be squeezed by the inner semi-ring 6 and the outer semi-ring 7 respectively, so that the two push rods 11 push the two arc-shaped supports 12 to approach each other, and at this time the two arc-shaped supports 12 can support the plastic bottle in the plug-in hole 5; when a pair of clamping assemblies rotate to outside the inner semi-ring 6 and the outer semi-ring 7 following the turntable 4, the two push rods 11 are separated from the inner semi-ring 6 and the outer semi-ring 7, and the two first springs 13 can respectively pull the two arc-shaped supports 12 to reset, so that the two arc-shaped supports 12 are away from each other, and at this time the plastic bottle can pass through the plug-in hole 5 and fall;

[0042] The separation mechanism is arranged on the base 1, and is used to separate the bottle cap from the bottle body;

[0043] The inner half ring 6 and the outer half ring 7 are used in conjunction with the feeding mechanism and the separating mechanism. When the plug-in hole 5 is rotated to the working area of ​​the feeding mechanism and the separating mechanism, the two arc-shaped supports 12 in a pair of clamping assemblies below the plug-in hole 5 are in a position close to each other, thereby supporting the plastic bottle in the plug-in hole 5;

[0044] When the separation mechanism removes the bottle cap from the plastic bottle, the plug-in hole 5 drives the plastic bottle to continue to rotate. When the pair of clamping components holding the plastic bottle are separated from the inner semi-ring 6 and the outer semi-ring 7, the two arc-shaped supports 12 are in a position away from each other, and the plastic bottle can pass through the plug-in hole 5 and fall, thereby completing the automatic feeding of waste plastic bottles, the automatic separation of the cap body, and the separate collection of the bottle cap and the bottle body. No human intervention is required, the degree of automation is high, and the efficiency can be effectively improved.

[0046] like Figure 1and Figure 2 When the cross arm 18 drives the fixed clamp 19 to rotate to one end of the conveyor belt 14, the conveyor belt 14 can deliver the plastic bottle to the fixed clamp 19. At this time, the movable clamp 21 is pushed by the first electric cylinder 20, so that the movable clamp 21 cooperates with the fixed clamp 19 to clamp the plastic bottle. Then the conveyor belt 14 stops conveying, and the clamped plastic bottle is driven by the cross arm 18 to rotate 180 degrees to the top of the plug-in hole 5. At this time, the plastic bottle is released and can fall into the plug-in hole 5, thereby completing the loading of the plastic bottle.

[0051] like Figure 1 , Figure 5 and Figure 6 When the plug-in hole 5 drives the plastic bottle to rotate to the separation mechanism, the plastic bottle is first pressed and fixed by the pressing assembly, and then the two lower plates 24 are pushed upward by the two second electric cylinders 23, thereby finally driving the two clamping seats 34 to move upward to the two sides of the bottle cap, and then the two clamping seats 34 are driven to approach each other by the third motor 36, so that the two clamping seats 34 clamp the bottle cap, and then the rotating ring 31 is driven to rotate by the driving assembly, and the two clamping seats 34 can drive the bottle cap to rotate, and in the process of unscrewing the bottle cap, the bottle cap can push the upper plate 27 to compress the second spring 26, thereby ensuring that the bottle cap can be smoothly unscrewed from the bottle body, completing the separation of the bottle cap and the bottle body.
