[0021] One end of the clamping head 77 located in the inner cavity of the placement groove 71 is an arc-shaped block.

[0022] The twisting groove 79 is wavy.

[0023] Specifically, the clamping head 77 can clamp the plastic bottle, facilitating subsequent squeezing of the bottle body and pouring of the liquid in the bottle. After clamping, it can also automatically and quickly eject the liquid in the bottle, causing the liquid to flow from the liquid inlet 74 into the recycling box.

[0024] In another embodiment provided by the present invention, the cutting mechanism 8 includes a first inserting rod 81 horizontally and movably inserted into the clamping head 77. One end of the first inserting rod 81 extends to the outside of the clamping head 77, and the end of the first inserting rod 81 extending outside the clamping head 77 is located in the inner cavity of the moving sleeve 76. A sliding frame 82 is fixedly connected to the end of the first inserting rod 81 away from the extending rod 78, and a second spring 810 is fixedly connected between one end of the sliding frame 82 and the clamping head 77. The sliding frame 82 is slidably arranged in the clamping head 77. A rotating rod 83 is arranged above the sliding frame 82, and the rotating rod 83 is rotatably arranged in the clamping head 77. A pulling rope 84 is wound around the outer wall of the central axis of the rotating rod 83. A rotating ring 85 is rotatably arranged inside one end of the clamping head 77 close to the extending rod 78. The other end of the pulling rope 84 is wound around the outer wall of the rotating ring 85. Inserting rods 89 are threadedly connected to the outer walls of two opposite ends of the rotating ring 85. The inserting rods 89 are inserted into the clamping head 77. The extending rod 78 is fixedly connected to the end of the inserting rod 89 away from the rotating ring 85. A first torsion spring 88 is fixedly connected between the outer wall of the central axis of the rotating rod 83 and the clamping head 77. A sliding plate 86 is rotatably arranged at one end of the clamping head 77 away from the extending rod 78, and a first spring 87 is fixedly connected between the sliding plate 86 and the moving sleeve 76.

[0025] A convex block is fixedly connected to the outer wall of the rotating rod 83, and the threads on the outer walls of two opposite ends of the rotating ring 85 are opposite.

[0026] Specifically, the cooperation of the clamping head 77 and the first spring 87 can automatically identify whether there is gas in the bottle. When the bottle is not sealed, cutting is not performed, saving the power cost.

[0027] In another embodiment provided by the present invention, the anti-fragmentation mechanism 9 includes a magnetic plate 91 fixedly connected to the inner wall of the moving sleeve 76, a magnetic block 92 fixedly connected to the inserting rod 89, a second torsion spring 93 fixedly connected between the outer wall of the rotating ring 85 and the box body 1, and a thorn needle 94 and a strip 95 fixedly connected to the outer wall of the end of the extending rod 78 away from the inserting rod 89.

[0028] There are two thorn needles 94 and two strips 95. The thorn needles 94 and the strips 95 are arranged adjacent to each other. The slot where the inserting rod 89 is located is a cross-shaped notch, and the magnetic poles of the opposite ends of the magnetic block 92 and the magnetic plate 91 are opposite.

[0029] Specifically, the strip 95 will replace the thorn needle 94 and be inserted into the cut opening. In this way, when the inserting rod 89 resets, it will not cut other positions of the bottle body, preventing strip-shaped plastic fragments from separating from the bottle body, thereby preventing the fragments from entering the cavity for collecting liquid and also preventing the fragments from blocking the liquid inlet, further improving the solid-liquid separation effect.

[0030] Working principle: When in use, place the plastic bottle into the placement groove 71. There is an infrared sensor in the placement groove 71. Then, the electric push rods 75 on both sides will move towards the middle, causing the moving sleeve 76 to drive the clamping head 77 to quickly move towards the middle. The clamping heads 77 on both sides can clamp the plastic bottle, facilitating subsequent squeezing of the bottle body and pouring of the liquid in the bottle, so that the liquid flows from the liquid inlet 74 into the recycling box. When the plastic bottle is in a sealed state due to the bottle cap, etc., the bottle body cannot be quickly flattened. When the clamping head 77 moves towards the middle, it will be compressed into the moving sleeve 76. Then, the first inserting rod 81 and the sliding carriage 82 will be squeezed towards the rotating ring 85, causing the rotating rod 83 to rotate reciprocally. Through the transmission of the rotating rod 83, the pull rope 84, the rotating ring 85, and the second inserting rod 89, the second inserting rods 89 at both ends can move reciprocally, enabling the thorn needle 94 to cut open the bottle body, allowing the liquid in the bottle to flow out. And when the thorn needle 94 moves reciprocally, the liquid in the bottle can flow out more smoothly from the cut opening, preventing blockage or slow flow of liquids with pulp, etc. If the bottle is not sealed, the first inserting rod 81 will not be squeezed and the thorn needle 94 will not move. It can automatically identify whether there is gas in the bottle. When the bottle is not sealed, it will not be cut, thus reducing mechanical energy loss and saving electricity costs; When the two moving sleeves 76 are closest to each other, the clamping head 77 will be squeezed into the moving sleeve 76. The guide rod 710 reciprocates in the twisting groove 79, which can drive the clamped plastic bottle to rotate automatically and reciprocally. Thus, whether it is a cut bottle or an unsealed bottle, the liquid in the bottle can be quickly thrown out, improving the solid-liquid separation rate; And when the clamping head 77 approaches the magnetic plate 91, the second inserting rod 89 will first move towards the rotating ring 85. After the second inserting rod 89 approaches the rotating ring 85, the clamping head 77 also gets closer to the magnetic plate 91. Thus, the magnetic block 92 gets closer to the magnetic plate 91, causing the magnetic block 92 to move further away from the magnetic plate 91 due to magnetism. Consequently, the second inserting rod 89 will rotate accordingly, and the strip 95 will replace the thorn needle 94 and insert into the cut opening. In this way, when the second inserting rod 89 resets, it will not cut other positions of the bottle body, preventing strip-shaped plastic fragments from separating from the bottle body, thereby preventing the fragments from entering the cavity for collecting liquid and also preventing the fragments from blocking the liquid inlet, further improving the solid-liquid separation effect; After squeezing is completed, start the motor 73 to rotate the rotating plate 72. The liquid in the plastic bottle has flowed into the liquid collection cavity from the liquid inlet 74. Then, the plastic bottle will fall onto the rotating plate 72. The rotating plate 72 is inclined, and the plastic bottle will automatically slide into the cavity for collecting solids, completing the solid-liquid separation; After collecting the bottles, it can print the photos to be printed for free by uploading or taking selfies, enabling convenient and environmentally friendly printing of any photos that users want to print. At the same time, paid printing can also be carried out, increasing people's attention to environmental protection and promoting the sustainable development of society.

Open the WeChat software on the mobile phone, scan the QR code of the WeChat mini-program of the recycling device, and collect the WeChat mini-program; S2: Select a photo or take a selfie through WeChat and upload the photo to be printed; S3: On the recycling device, enter the verification code, download the photo, and the photo is displayed on the screen of the recycling device; S4: After the printing options are set, click Preview.
