The screening machine body 1 in this technical solution is equipped with a vibration mechanism at its bottom. This mechanism is conventional technology in the field and has no relation to the technical problem in this technical solution. Therefore, it will not be described in detail in this technical solution. In specific use, the collected waste paper is put into the screening box 8. After being driven by the vibration mechanism of the screening machine body 1 below, the heavier and smaller metal fragments and plastic particles, fragments and other impurities are screened and fall down, and are discharged through the waste outlet at the bottom of the screening machine body 1 and then recycled according to various types of waste.

The inner wall of the screening frame 3 abuts against the screening mesh frame 4. The bottom of the screening mesh frame 4 is connected to the bottom block 5. The sidewall of the bottom block 5 abuts against the sidewall of the fixing block 6. The sidewall of the fixing block 6 is transversely connected to the first fixing bolt 7. One side of the first fixing bolt 7 is threadedly connected to the bottom block 5. The top surface of the screening frame 3 is connected to the screening box 8. One side of the screening box 8 is provided with a connecting pipe 9. The open end of the connecting pipe 9 is threadedly connected to the air supply pipe 10. The other side surface of the air supply pipe 10 is connected to the flange 11. The sidewall of the flange 11 is threadedly connected to the second fixing bolt 12. The sidewall of the second fixing bolt 12 is threadedly connected to the air outlet of the blower 13. The bottom of the blower 13 is installed on the top of the mounting bracket on one side of the screening machine body 1.
[0023] Preferably, the screening machine body 1, the rotating shaft 2 and the screening frame 3 form a rotating connection structure. The front end of the screening machine body 1 is provided with two rectangular protrusions, and the protrusions are threadedly connected to the surface of the front protrusions of the screening frame 3 by bolts.
[0024] In practical use, the bolts fixed to the front end of the screening machine body 1 and the screening frame 3 can be unscrewed, thereby using the rotating shaft 2 at the rear end of the screening frame 3 to rotate the screening frame 3 upward.
[0025] Preferably, the side wall of the screening rack 3 has a rectangular through groove, and the shape and size of the through groove are adapted to the screening rack 4.
[0026] In practical use, the through groove opened on the side wall of the screening rack 3 makes it easy to place the screening mesh rack 4 inside to screen waste paper.
[0027] Preferably, the screening frame 3, the screening mesh frame 4, the bottom block 5, the fixing block 6 and the first fixing bolt 7 form a threaded connection structure.
[0028] In practical use, the screening frame 4 can be disassembled for cleaning and replacement by removing the first fixing bolt 7 between the bottom block 5 and the fixing block 6 at the bottom of the screening frame 3 and the screening mesh frame 4.
[0029] Preferably, the top of the screening box 8 is provided with a feed inlet, one side of the screening box 8 is provided with a connecting pipe 9, and the other side of the screening box 8 is provided with a discharge outlet, and the inner wall of the connecting pipe 9 is provided with a filter screen.
[0030] In actual use, the waste paper in the screening box 8 is moved to the other side by the air blown out of the blower 13 transmitted through the air supply pipe 10 connected to the threaded pipe 9 on one side, and then discharged from the discharge port on the other side of the screening box 8.
[0031] Preferably, the connecting pipe 9, the air supply pipe 10, the flange 11, the second fixing bolt 12, and the blower 13 form a threaded connection structure.
[0032] In practical use, unscrew the air supply pipe 10 fixed on the connecting pipe 9, and then unscrew the second fixing bolt 12 fixed between the flange 11 and the blower 13. The air supply pipe 10 can then be disassembled for cleaning and replacement.
[0033] Working Principle: During waste paper recycling, the collected waste paper is fed into the feed inlet at the top of the screening box 8 on the upper part of the screening machine body 1. Then, the vibrator at the bottom of the screening machine body 1 is activated, driving the upper screening frame 3 and screening mesh frame 4 to vibrate. This causes the metal fragments and other impurities mixed in with the waste paper falling on the screening mesh frame 4 to vibrate and fall down. The screened metal fragments and other impurities fall into the screening machine body 1 below and slide to the other side through the inclined structure of its inner wall, and are then discharged from the waste outlet below. The waste paper in the upper screening box 8 is moved to the other side by the air blown out by the blower 13, which is transmitted through the air duct 10 connected to the threaded pipe 9 on one side. Discharged from the outlet on the other side of the screening box 8, when the blower 13 blows air into the screening box 8 through the connecting pipe 9, the filter screen installed in the connecting pipe 9 can intercept impurities, preventing waste paper and impurities from accidentally entering the air conveying pipe 10 and causing blockage, so as to complete the screening of impurities in the waste paper, thereby improving the efficiency of subsequent processing and the quality of the finished paper. After processing is completed, the bolts fixed to the front end of the screening machine body 1 and the screening frame 3 can be unscrewed, so that the screening frame 3 can be rotated upward by the rotating shaft 2 at the rear end of the screening frame 3, and the screening frame 4 can be disassembled for cleaning and replacement by removing the first fixing bolt 7 between the bottom block 5 and the fixing block 6 at the bottom of the screening frame 3 and the screening screen frame 4.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
