The guide rail 101 is used to transport the bottom plate 102 to the cutting station along the negative direction of the first direction x, and output the bottom plate 102 after cutting along the positive direction of the first direction x. Since more residues will be generated during the laser cutting process, more PET particles and debris will remain on the top of the material plate 201 when the cutting is completed. At this time, the bottom plate 102 is transported along the first direction When moving in the positive direction of x, when the bottom plate 102 moves to the recycling station, the tilting plate 103 rotates under the driving action, so that the material plate 201 assembled on the tilting plate 103 is deflected as a whole.

[0031] See also Figure 3In a preferred embodiment of the present invention, the material plate assembly 2 also includes a limiting hole 203, and several of the limiting holes 203 are arranged on the material plate 201 and coaxially arranged with the through hole 202. The limiting holes 203 are arranged toward the side of the lifting plate 104, and the lifting plate 104 is also fixedly equipped with several top columns 105, and the top columns 105 are positioned and assembled in the through hole 202 and the limiting holes 203.

[0032] In actual application of this embodiment, a limiting hole 203 is coaxially arranged on the through hole 202, and the diameter of the limiting hole 203 is smaller than the diameter of the through hole 202. The diameter of the through hole 202 and the diameter of the top column 105 are matched to each other, so that the lifting plate 104 is suspended in the through hole 202 through a plurality of top columns 105, and when the lifting plate 104 is lifted along the second direction y, the top column 105 is always kept inside the through hole 202, so that a sliding sealing state is maintained between the top column 105 and the through hole 202, thereby preventing PET particles from falling along the gap.

Since the bottoms of the plurality of chute cavities 206 are provided with outlets 207, the PET particles can be discharged through the outlets 207.

[0035] See also Figure 5In a preferred embodiment of the present invention, the transmission mechanism 3 also includes a first linkage arm 305, a second linkage arm 306, a third transmission wheel 307, a fourth transmission wheel 308 and a fifth transmission wheel 309, one end of the first linkage arm 305 is coaxially rotatably connected with the first transmission wheel 303, the other end of the first linkage arm 305 is rotatably equipped with the fourth transmission wheel 308, one end of the second linkage arm 306 is rotatably assembled on the fourth transmission wheel 308, the other end of the second linkage arm 306 is fixedly rotatably assembled on the material plate 201, the fifth transmission wheel 309 is rotatably assembled at the end of the second linkage arm 306, the third transmission wheel 307 is coaxially fixedly connected with the first transmission wheel 303, a synchronous belt is assembled between the third transmission wheel 307 and the fourth transmission wheel 308 and between the fourth transmission wheel 308 and the fifth transmission wheel 309, and a toothed plate 107 is also provided on one side of the lifting plate 104, and the toothed plate 107 and the fifth transmission wheel 309 are meshed and connected.

Since the first linkage arm 305 and the second linkage arm 306 are rotationally connected through the fourth transmission wheel 308, the roll plate 103 always maintains a linkage state with the ratchet 301 in the rotating state.

[0037] See also Figure 6 and Figure 8 In a preferred embodiment of the present invention, the collecting assembly 4 comprises a temporary storage box 401, a top notch 402, a discharge port 403, a baffle 404, a slide slot 405 and a recovery trough 406. The temporary storage box 401 is elastically slidably assembled at the bottom of the collecting box 204 in the horizontal direction. A plurality of top notches 402 are arranged on the top of the temporary storage box 401. The top notches 402 and the side holes 205 are matched. A discharge port 403 is also arranged at one end of the temporary storage box 401. One end of the baffle 404 is slidably inserted in the discharge port 403. The other end of the baffle 404 is fixedly assembled on the material plate 201. A slide slot 405 is also arranged on the baffle 404.

[0038] In actual application of this embodiment, the temporary storage box 401 is elastically slidably assembled on the bottom of the collection box 204 along the first direction x, and the top notches 402 at the bottom of the temporary storage box 401 are matched with the guide outlet 207. When the bottom plate 102 is located at the cutting station, the top notches 402 and the guide outlet 207 are in a closed state to prevent the particle components collected inside the temporary storage box 401 from flying. When the bottom plate 102 is located at the collecting station, the top notches 402 and the guide outlet 207 are in an open state to allow the particles on the surface of the material plate 201 to be removed along the inclined surface. The groove cavity 206 and the guide outlet 207 slide and fall into the inner cavity of the temporary storage box 401, and the discharge port 403 on one side of the temporary storage box 401 is switched to an open state at the same time. When the bottom plate 102 is located at the collection station, the temporary storage box 401 moves in the negative direction of the first direction x under the pressure, so that the baffle 404 slides synchronously in the discharge port 403, and the slide slot 405 on the baffle 404 slides to the inside of the discharge port 403, thereby making the discharge port 403 in a conducting state, thereby transporting the particulate components collected in the temporary storage box 401 to the recovery tank 406.

[0039] See also Figure 6 and Figure 7 In a preferred embodiment of the present invention, the transmission mechanism 3 also includes a baffle plate 312, and the baffle plate 312 is elastically rotationally limited and assembled on the side bracket 310. The collection component 4 also includes a trigger plate 407, and the trigger plate 407 is fixedly assembled at the bottom of the temporary storage box 401, and the baffle plate 312 and the trigger plate 407 are movably abutted against each other.

[0040] In actual application of this embodiment, the baffle plate 312 is elastically limited and rotatably assembled on the side bracket 310. When the bottom plate 102 moves to the collecting station side along the first direction x, the baffle plate 312 first abuts against the trigger plate 407. When the baffle plate 312 abuts against the groove on one side of the trigger plate 407, it can push the temporary storage box 401 to move in the negative direction of the first direction x relative to the material plate 201, thereby switching the top cavity and the bottom cavity of the temporary storage box 401 to the open state. Then, the particulate components are collected and transported. When the temporary storage box 401 moves to the extreme position, the trigger plate 407 pushes the baffle plate 312 to rotate clockwise until the baffle plate 312 rotates to the bottom side of the trigger plate 407. The temporary storage box 401 automatically resets to the initial position under the action of the elastic force, and when the bottom plate 102 moves to the cutting station in the negative direction of the first direction x, the baffle plate 312 rotates counterclockwise under the elastic pressure and does not form abutment with the trigger plate 407.

[0041] The above embodiment of the present invention provides a laser cutting device for a mobile phone screen protective film. By arranging a tiltable tilting plate 103 and a material plate 201 on the bottom plate 102, and arranging a collecting component 4 for recovering particulate components on one side of the material plate 201, the particulate components on the surface of the material plate 201 can be automatically collected and recovered during the cutting process, thereby improving the cleanliness of the product and reducing cost loss by recovering reusable raw material components.
