The side plate... 108 is detachably connected to the collection box 106 and slidably connected to the sealing seat 107, and is symmetrically arranged. The sliding plate 109 is slidably connected to the front side plate 108 and the bottom of the collection box 106, and is located above the bottom discharge port of the collection box 106. A plurality of mounting seats 110 are arranged in a row on the sealing seat 107. The electromagnet device 111 is arranged at the bottom of the mounting seat 110. The stirring device is arranged between the side plates 108 and is partially located in the cavity formed by the collection box 106 and the sealing seat 107. A fixing plate is provided on the right side of the base 103 for easy fixing with bolts. The base 103 is used for equipment support. The inclined guide plate 105 is installed on the inner top side with bolts. The guide seat 104 is directly welded inside the half shell of the crusher 101 and is fitted during the assembly of the half shell of the crusher 101. One of the fitting end faces is provided with a positioning hole, and the other fitting end face is provided with a positioning pin. The connecting part at the bottom of the guide seat 104 is connected to the top of the base 103 with bolts. The collection box 106 is fixed with bolts. Its bottom is a semi-circular arc structure and is provided with a through discharge port. The top of the discharge port is provided with a sliding groove to facilitate the sliding plate 109. The sealing seat 107 is fixed with two bolts. The bolts are symmetrically arranged to facilitate subsequent disassembly. The side plate 108 is installed on the front and rear end faces of the collection box 106 with bolts. The front side plate 108 has a through groove for the sliding plate 109 to slide, and the rear side plate 108 is provided with a through limiting groove for the rear end of the sliding plate 109 to be limited.

This structure facilitates the installation or removal of the slide plate 109, and the T-shaped threaded pin locks it in place on the side plate 108, making subsequent disassembly convenient.

[0026] Then, the front end of the auger 112 is rotatably connected to the front side plate 108, and the rear end is connected to the drive assembly; the drive assembly is located on the rear side plate 108 near the auger 112. The mounting ends on both sides of the auger 112 are respectively mounted on the side plate 108 via rotating bearings, and the drive assembly is used to drive the auger 112 to rotate.

[0027] Finally, the stirring motor 113 is mounted on the rear side plate 108; the coupling 114 is connected to the output shaft of the stirring motor 113 and the rear connecting shaft end of the auger 112, respectively. The stirring motor 113 is fixed by bolts, and the output shaft of the stirring motor 113 is connected and fixed to the connecting shaft of the auger 112 through the coupling 114.

[0028] When using this utility model to solve the problem that existing equipment cannot screen and remove iron impurities in waste paper shreds, thus reducing the effectiveness of subsequent waste recycling, the waste paper is first shredded by the shredder 101 during recycling. The shredded waste is guided by the guide seat 104 and falls into the base 103. Further, the waste falls into the collection box 106 for storage under the action of the inclined guide plate 105. At this time, the stirring motor 113 is controlled to intermittently rotate forward and reverse to drive the spiral auger 112 to rotate and stir the waste. At the same time, the electromagnet device 111 is energized. After being energized, the electromagnet has magnetism and can attract iron impurities in the moving waste. Finally, the sliding plate 109 is slid out to open the discharge port at the bottom of the collection box 106, and the iron-removed waste can fall directly into the receiving box at the bottom of the discharge port of the collection box 106 for centralized collection. During processing, the electromagnet device 111 can be continuously powered to enable continuous processing. During subsequent cleaning, the device remains powered on, and the slide plate 109 is pulled off to completely remove the waste material inside the collection box 106. The stirring device can be controlled to move slowly during material feeding. Then, the two fixing bolts of the sealing seat 107 are removed, allowing the sealing seat 107 to be removed directly. After removal, the electromagnet device 111 is moved above the iron impurity receiving box. After power is cut off, the impurities fall and the processing is completed. The cleaning time of the electromagnet device 111 is timed according to the actual waste paper processing time to ensure a good iron removal effect. This solves the problem that existing equipment cannot screen and remove iron impurities in waste paper shreds, which reduces the efficiency of subsequent waste reuse.
