[0027] The present invention is further described in detail below with reference to examples and specific implementation modes.

[0028] Embodiment 1:

[0029] like Figures 1 to 4 As shown, a wind-powered paper-plastic separation fiberizing machine is used for paper-plastic separation, comprising: a box body 1, the box body 1 is mainly used to store separated paper-plastic fibers, a pot body 2 is fixedly connected inside the box body 1, the pot body 2 is provided with an inlet 201 and two outlets, the inlet 201 is used to drive the paper-plastic into the pot body 2, the two outlets are a heavy residue outlet 202 and a light residue outlet 203, the heavy residue outlet 202 is mainly used to drive large particle impurities to be removed, the large particles mainly include large particle materials such as stones adsorbed on the paper-plastic, the light residue outlet 203 is mainly used to discharge small plastic pieces separated from the paper-plastic, a heavy residue separation area 205 is provided at the bottom of the pot body 2, and the heavy residue outlet 202 is arranged at the bottom of the heavy residue separation area 205.

[0030] An upper rotor and a lower rotor are rotatably arranged in the pot body 2, a plurality of blades 4 are fixedly connected to the rotor 3, preferably six blades 4, and the blades 4 are arranged at equal angles around the axis of the rotor 3, and a feeding pipe is provided in the box body 1, and the feeding pipe extends into the pot body 2, and a plurality of feeding ports 201 are provided between the upper rotor and the lower rotor. The feeding port 201 is mainly used to drive the unprocessed paper plastic into the pot body 2.

[0031] A lifting area 401 is provided at the connection between the multiple blades 4 of the lower rotor and the feed port 201. The lifting area 401 is an annular groove. When the blades 4 of the lower rotor rotate, the paper plastics from the feed port 201 will move from the lifting area 401 to the upper rotor 3.

[0032] The blades 4 of the upper rotor drive the paper plastic to rotate, and under the action of centrifugal force, the paper plastic contacts the inner wall of the pot body 2. The upper rotor and the lower rotor have the same rotation speed.

[0033] The upper rotor and the lower rotor are provided with arc scrapers 7 at intervals at the extension section of the blade tip 4, and the arc scrapers 7 of the upper rotor 3 and the arc scrapers 7 of the lower rotor 3 are arranged in a staggered manner in space. The staggered arc scrapers 7 extend out of the blades, which is conducive to cleaning the screen plate at the junction of the two blades 4 of the same rotor (mainly to drive the fibers stuck on the screen plate to be separated).

[0034] The paper plastic contacts the inner wall of the pot body 2 under the action of the rotor 3. A plurality of rollers 6 are arranged in rotation in the pot body 2. The plurality of rollers 6 are arranged around the rotation center of the rotor 3. The outer surface of the roller 6 is provided with a crushing part in contact with the paper plastic. The pot body 2 is provided with a crushing area cooperating with the roller 6. A small gap is provided between the crushing part of the roller 6 and the blade 4. When the paper plastic moves to the small gap, the crushing part cooperates with the blade 4 to drive the paper plastic to separate. The bottom of the roller 6 extends to the outside of the pot body 2 and cooperates with the motor. The motor drives the roller 6 to rotate around the axis of the stick itself. The rotation direction of the roller 6 is opposite to that of the rotor 3. The rotation speed of the rotor 3 is higher than that of the roller 6, and there is a speed difference between the rotor 3 and the roller 6.

[0035] The blades 4 of the upper rotor and the lower rotor rotate, and drive the paper-plastic to cooperate with the crushing part of the roller 6, thereby driving the paper-plastic to be separated in the pot body 2.

[0036] The crushing part adopts needle teeth arranged on the outer circumferential surface of the roller 6, and the density of the needle teeth is 100-150 teeth / square inch, wherein 150 teeth / square inch is preferred. The rotating roller 6 drives the needle teeth to contact with the paper plastic, thereby driving the paper plastic to separate fibers. The roller 6 of this embodiment adopts a needle-tooth roller, and its main function is to drive the fiber separation of the paper plastic.

[0037] A guide area 204 is provided on the top of the pot body 2, and a conical sieve plate (consistent with the shape of the guide area) is fixedly connected to the guide area. The conical sieve plate also improves the screening efficiency. The upper rotor is provided with a first guide blade that cooperates with the upper guide area 204, and the lower rotor is located in the heavy slag separation area 205 and is provided with a second guide blade.

[0038] The crushing part of the roller 6 cooperates with the scraper to drive the fiber separation. The pot body 2 is fixedly connected with a screen plate 5, which is provided with a screen slot extending into the box body 1. The separated fibers are transported from the screen plate 5 to the box body 1. The box body 1 is provided with a fiber discharge port connected to the outside. The screen plate 5 is provided with a plurality of screen slots, which gradually expand from the inside to the outside. The screen slots facilitate the separated fibers to enter the box body 1, and the screen slots connect the pot body 2 and the box body 1.

[0039] A plurality of crushing convex points are arranged on the blades of the rotor, and the crushing convex points are arranged on the windward surface of the blades.

[0040] like Figures 1 to 4As shown, during operation, the paper plastic enters the pot body 2 from the feed inlet 201, and the lower rotor blade drives the paper plastic from the feed inlet 201 into the lifting area 401, large particles are discharged from the heavy residue discharge port 202, and the separated small plastic pieces are discharged from the light residue discharge port 203, thereby improving the overall separation effect.

[0041] The fan blade drives the paper plastic upward to contact with the upper rotor. During the rotation of the upper rotor and the lower rotor, part of the paper plastic is at the upper rotor and part of the paper plastic is at the lower rotor. The rotation of the two rotors will drive the paper plastic upward or downward, so that the paper plastic can fully contact with the blades 4 and the crushing part. The blades 4 drive the paper plastic to cooperate with the crushing part of the roller 6. Under the action of the blades 4 and the crushing part of the roller 6, the paper plastic separation part fibers are driven, and the separated paper plastic fibers are discharged from the screen gap of the screen plate 5.

[0042] Embodiment 2:

[0043] like Figures 5 to 8 As shown, a wind-powered paper-plastic separation fiberizing machine is used for paper-plastic separation, comprising: a box body 1, the box body 1 is mainly used to store the separated paper-plastic fibers, the box body 1 is provided with a paper-plastic fiber discharge port, and the paper-plastic fiber discharge port is connected to a storage box. A pot body 2 is fixedly connected to the box body 1, and the pot body 2 is provided with an inlet 201 and two outlets. The inlet 201 is used to drive the paper-plastic into the pot body 2, and the two outlets are a heavy residue outlet 202 and a light residue outlet 203, and a light residue outlet 203 is opened above the pot body 2.

[0044] The box body 1 is provided with a feed inlet, and the rotor 3 is provided with a guide cone at the feed inlet. When the rotor 3 rotates, negative pressure is formed, and the paper plastic enters the pot body 2 from the feed inlet. Under the action of the guide cone, the paper plastic moves evenly around the rotor 3, reducing the phenomenon of paper plastic accumulation.

[0045] The box body 1 is provided with a light slag guide area 101 at the light slag discharge port 203 of the pot body 2. The light slag guide area 101 is provided with a conical guide plate, which passes through the light slag discharge port and extends to the inside of the pot body 2, and the conical guide plate divides the light slag discharge port into an inlet 201.

[0046] The conical guide plate gradually expands outward from the light slag discharge port of the pot body 2 to form an inclined cone. The box body 1 is provided with a light slag discharge port. The light slag (lighter materials such as plastic film) contacts the conical guide plate when being discharged from the light slag discharge port 203, and is finally discharged from the light slag discharge port.

[0047] The heavy slag discharge port 202 is mainly used to drive the large particles of impurities to be discharged. The large particles of impurities mainly include large particles such as stones adsorbed on the paper plastic. The light slag discharge port 203 is mainly used to discharge small plastic pieces separated from the paper plastic. A heavy slag separation area 205 is provided at the bottom of the pot body 2, and the heavy slag discharge port 202 is set at the bottom of the heavy slag separation area 205.

[0048] A rotor 3 is provided for rotation inside the pot body 2, and a plurality of blades 4 are fixedly connected to the rotor 3. The plurality of blades 4 are arranged at equal angles around the axis of the rotor 3. Six blades 4 are preferably used in this embodiment. The rotor 3 is provided with arc scrapers 7 at intervals at the extension section of the blade tip 4. The arc scrapers 7 arranged at intervals improve the cleaning effect of the screen plate.

[0049] The paper plastic contacts the inner wall of the pot body 2 under the action of the blade 4. A plurality of rollers 6 are arranged at equal angles around the rotation center of the rotor 3 for rotation in the pot body 2. The outer surface of the roller 6 is provided with a crushing part in contact with the paper plastic. The pot body 2 is provided with a crushing area cooperating with the roller 6. A small gap is provided between the crushing part of the roller 6 and the blade 4. When the paper plastic moves to the small gap, the crushing part cooperates with the blade 4 to drive the paper plastic to separate. The bottom of the roller 6 extends to the outside of the pot body 2 and cooperates with the motor. The motor drives the roller 6 to rotate around the rotation axis. The motor drives the roller 6 to rotate in order to give the roller 6 centrifugal force, so as to facilitate the separation of the paper plastic adsorbed on the roller 6. The crushing part adopts a grooved form (a plurality of circular rings arranged around the axial direction). The rotation speed of the rotor 3 is 3-4 times that of the roller 6, and the rotation direction of the rotor 3 is opposite to that of the roller 6. The roller 6 of this embodiment adopts a grooved roller, and its main function is to achieve paper plastic separation.

[0050] The pot body 2 is provided with a sieve plate 5 between two rollers 6. The sieve plate 5 is provided with multiple corrugated holes 501, which gradually expand from the inside to the outside. The sieve plate 5 is provided with multiple corrugated parts, each of which is provided with a long side 5021 and a short side 5022. The long side 5021 of the corrugated part is connected with the short side 5022 of the adjacent corrugated part, and the corrugated hole 501 is arranged perpendicular to the long side 5021. During the rotation of the rotor 3, centrifugal force is generated to drive the separated paper plastic to cooperate with the corrugated hole 501. The connecting line between the short side 5022 and the long side 5021 and the rotation center of the rotor 3 is used as an auxiliary line. The angle between the long side 5021 of the corrugated part and the auxiliary line is 61 degrees, and the angle between the short side 5022 and the auxiliary line is 30 degrees.

[0051] When the separated paper plastic contacts the corrugated holes 501 on the long side 5021, turbulence is formed on the short side 5022, and the turbulence changes direction to facilitate the paper plastic to move toward the corrugated holes 501, driving the paper plastic fibers to be discharged from the corrugated holes 501, thereby reducing the blockage phenomenon during the separation process.

[0052] The plurality of corrugated portions are all provided with corrugated holes 501 , and the number of the corrugated holes 501 is different and they are staggered in space to improve the screening effect.

[0053] like Figures 5 to 8 As shown, during operation, negative pressure is formed when the rotor 3 rotates, and the paper plastic enters the pot body 2 from the feed port. Under the action of the guide cone, the paper plastic moves evenly around the rotor 3, reducing the phenomenon of paper plastic accumulation.

[0054] After the paper plastic enters the rotor 3, the blades 4 drive the paper plastic to contact the side wall of the pot body 2 under the action of centrifugal force. When the paper plastic moves to a smaller gap, the crushing part cooperates with the blades 4 to drive the paper plastic to separate.

[0055] After the separation of paper and plastic, the heavy residue is discharged from the heavy residue discharge port 202, and the light residue (lighter materials such as plastic film) is discharged from the light residue discharge port 203 and contacts the conical guide plate, and is finally discharged from the light residue discharge port.

[0056] During the separation process, if the paper plastic that meets the specifications is discharged from the corrugated hole 501, the turbulence formed by the short edge 5022 during the discharge process accelerates the discharge of the paper plastic.

[0057] Unqualified paper plastics continue to be separated in the pot body 2 until they meet the standards and are discharged from the corrugated holes 501.

[0058] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
