DETAILED DESCRIPTION

[0012] In order to further understand the purpose, structure, features, and functions of the present invention, the following detailed description is made in conjunction with the embodiments. Figure 1 and Figure 2 As shown, an OCC screen for sorting waste cardboard in recyclables and a sorting method thereof include a protection device 1, a feed port 2, a drive device 3, a motor 4 and a discharge port 5, wherein the protection device 1 includes a cover plate 110 and a side shield 120, as shown in FIG. Figure 3 As shown, it also includes a baffle 130, an inner baffle 140 and a seat bearing 150. The cover plate 110 is spliced ​​together by a plurality of blocks. The cover plate 110 is arranged at the upper end and the rear end of the protective device 1. The left and right sides of the top of the cover plate 110 are fixedly connected with handles 111 to facilitate opening the cover plate to observe the use of the drive device 3 or to perform maintenance. The cover plate 110 is connected and fixed to the baffle 130 by special screws. The side shield 120 is fixed to the outside of the first baffle 131 of the baffle 130 by special screws. The side shield 120 wraps the part of the drive device 3 located outside the first baffle 130. The side surface of the side shield 120 is provided with a through hole for the working gear 410 of the motor 4 to pass through. The motor 4 is fixed to the side of the side shield 120. The motor 4 has two respectively arranged in the middle of the side shield 120. The feed port 2 is in the shape of a hole, and the lower end opening of the feed port 2 is fixedly connected to the cover plate 110, and the cover plate 110 is provided with the same opening at the corresponding position, which is convenient for connecting the feed port 2 to allow the garbage to enter the protective device 1, and the discharge port 5 is the same as the block shape of the cover plate 110, and the discharge port 5 is fixed to the front end of the protective device 1 by special screws, and the surface of the discharge port 5 is provided with an opening corresponding to the position of the drive device 3 to facilitate the passage of the screened garbage; the drive device 3 is provided with multiple and horizontally fixed side by side between the two baffles 130, and the sieve plates 320 of the adjacent drive devices 3 are staggered, so that the flexible materials in the mixed garbage can be stirred to screen out the flexible materials.

[0013] like Figure 3 and Figure 4As shown, the baffle 130 includes a first baffle 131 and a second baffle 132, which are respectively arranged on the left and right sides of the protective device 1, the first baffle 131 is provided with a plurality of horizontally distributed through circular holes, the inner wall of the through circular holes is fixedly connected to the seat bearing 150, the inner wall of the second baffle 132 is provided with a non-through hole corresponding to the first baffle 131, the inner wall of the hole on the second baffle 132 is fixedly connected to the same seat bearing 150, the rotating shaft 310 is provided with one end of the shaft end baffle 360 ​​passing through the seat bearing 150 on the first baffle 131, and the rotating shaft 310 is fixedly connected to the inner ring of the seat bearing 150, and the transmission of the driving device 3 The sprocket 340 and the driven gear 350 are both arranged on the outside of the first baffle 131, and the other end of the rotating shaft 310 is fixedly connected to the inner ring of the seat bearing 150 on the second baffle 132; the inner baffle 140 is arranged on the inner wall of the baffle 130 at both ends of the driving device 3, and the inner baffle 140 is a right-angled trapezoid, the height of the right-angled trapezoid is parallel to the rotating shaft 310, and the hypotenuse is inclined toward the sieve plate 320 of the driving device 3, the shorter bottom side of the right-angled trapezoid is close to the sieve plate 320, and the shorter bottom side length is equal to the distance from the highest point of the sieve plate 320 to the rotating shaft 310. Such a design can reduce the problem of flexible materials being entangled with the rotating shaft 310 at both ends of the driving device 3.

[0014] like Figure 5 The driving device 3 shown includes a rotating shaft 310, a sieve plate 320, a spacer sleeve 330, a transmission sprocket 340, a driven gear 350, a shaft end baffle 360 ​​and a locking circular nut 370. The sieve plate 320 and the spacer sleeve 330 are both Lello triangles. Holes are provided in the centers of the sieve plate 320 and the spacer sleeve 330. The cross-sectional area of ​​the sieve plate 320 is greater than the cross-sectional area of ​​the spacer sleeve 330. The rotating shaft 310 is a cylinder. There are multiple sieve plates 320 and spacer sleeves 330, which are alternately sleeved on the rotating shaft 310 through the center circular holes. A thread is provided on the surface of a middle section of the rotating shaft 310. A total of two locking circular nuts 370 are sleeved on the rotating shaft 310 through threads. The two locking circular nuts 370 are arranged on the sieve plates that are alternately distributed. 320 and both sides of the spacer sleeve 330, and two locking round nuts 370 clamp all the sieve plates 320 and the spacer sleeves 330, and the multiple sieve plates 320 and the spacer sleeves 330 are in a parallel relationship and the fixing angles are exactly the same. Such a design can allow the spacer sleeves 330 of the same shape to assist in stirring when the sieve plate 320 stirs the flexible garbage. The large and small Lello triangles also have good advantages in preventing winding. The shaft end baffle 360 ​​is fixedly connected to one end of the rotating shaft 310, and the transmission sprocket 340 is fixedly connected to the rotating shaft 310. The transmission sprocket 340 is located close to the shaft end baffle 360, and the driven gear 350 is fixedly connected to the rotating shaft 310 and is arranged at the rear end of the transmission sprocket 340.

[0015] like Figure 6 As shown, the transmission sprockets 340 of all the driving devices 3 are on the same horizontal line, the driven gears 350 are also on the same horizontal line, the working gear 410 of the motor 4 is meshed with the driven gear 350 of the driving device 3, and the remaining driving devices 3 are connected by a special chain. The transmission sprockets 340 of adjacent driving devices 3 are linked in pairs, and the adjacent driven gears 360 are also linked in pairs. The transmission sprockets 340 and driven gears 360 on the same driving device 3 are respectively linked to the adjacent driving devices 3 on the left and right.

[0016] When in use, the starting motor 4 drives the meshing transmission sprocket 340 to rotate through the working gear 410, and the rotation of the transmission sprocket 340 drives the driven gear 350 at the rear end to rotate, and the driven gear 350 cooperates with the special chain to drive other driving devices to rotate together, and then the mixed recyclables are sent into the protective device 1 from the upper end of the feed inlet 2, and the mixed recyclables are transmitted through the rotating sieve plate 320. Because the sieve plate 320 is a Lello triangle, the large pieces of old cardboard can be pushed forward smoothly with the help of this unique shape, because the long sheet of hard materials is in a lifted state during the screening process, and finally on the sieve plate The sieve plates 320 are driven by the screen 320 and are transported out from the discharge port 5. The smaller materials in the mixed recyclables fall from the gap between the sieve plates 320 and 320. The large flexible materials will also fall from the gap between the sieve plates 320 under the stirring of the sieve plates 320 due to their material characteristics. The alternating large and small Lello triangular plates have a complex rotating spatial structure and the characteristic that only one vertex is in contact with the contact surface during rotation, which effectively reduces the occurrence of entanglement problems. The trapezoidal inner baffles 140 at both ends of the driving device 3 can reduce the problem of flexible materials being entangled with the rotating shaft 310 at both ends of the driving device 3.

[0017] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
