Description

Technical Field

[0001] The utility model relates to the field of paper shredders, in particular to a wear-resistant paper shredder cutter which can prevent paper from curling. Background Art

[0002] A shredder is a commonly used office equipment that can help people deal with waste office paper. When using an existing shredder, the user needs to turn on the main power first, manually align the paper to be processed with the paper input port of the shredder, and advance it a certain depth. After the infrared detection device set at the paper input port detects the paper, it triggers the control circuit to start the series motor to drive the roller to shredder the paper.

[0003] However, the prior art has the following defects:

[0004] The two blade tips of the existing shredders are relatively concentrated at the points of action on the paper, resulting in low paper shredding efficiency. There is a gap between the blades and the assembly precision is low, which not only makes it easy for the blades to be squeezed and worn, but also makes it easy for paper jams, paper curling and loose blade groups to occur during use, all of which affect the working efficiency of the shredder. Utility Model Content

[0009] By adopting the above technical solution, the first adjusting block and the second adjusting block can slide back and forth inside the first groove and inside the second groove.

[0010] The cross-sectional shape of the first mounting seat and the second mounting seat is U-shaped. A first threaded through hole is opened on one side of the first mounting seat, and a second threaded through hole is opened on one side of the second mounting seat.

[0011] By adopting the above technical solution, the first adjusting block and the second adjusting block are located inside the first groove and the second groove, which can prevent them from falling off.

[0012] A first connecting member is fixedly installed on one side of the first adjusting block close to the first threaded through hole, a first screw is rotatably installed on the first connecting member, the first screw is threadedly connected to the first threaded through hole, and a first rotating handle is fixedly installed on one end of the first screw away from the first adjusting block.

[0013] By adopting the above technical solution, the first screw rod can be driven by rotating the first rotating handle to adjust the position of the first adjusting block, thereby adjusting the distance between the two rotating shafts.

[0014] A second connecting piece is fixedly installed on one side of the second adjusting block close to the second threaded through hole, a second screw is rotatably installed on the second connecting piece, the second screw is rotatably connected to the second threaded through hole, and a second rotating handle is fixedly installed on one end of the second screw away from the second adjusting block.

[0015] By adopting the above technical solution, the second adjusting block can slide on the second slide rail as the second screw rotates, so as to facilitate the adjustment of the position of the second adjusting block.

[0016] A first rotating connection member is fixedly installed on one end of the first mounting seat close to the first threaded through hole, and a second rotating connection member is fixedly installed on one side of the first adjusting block. A first rotating shaft and a second rotating shaft are rotatably installed on the first rotating connection member and the second rotating connection member, respectively. A first servo motor and a second servo motor are respectively provided on one end of the first rotating shaft away from the first mounting seat and one end of the second rotating shaft away from the first adjusting block.

[0017] By adopting the above technical solution, the first servo motor and the second servo motor are turned on to drive the first rotating shaft and the second rotating shaft to rotate, thereby driving the blade group to rotate and start to shred the paper.

[0018] The blade assembly comprises a plurality of blade shafts, a plurality of blade bodies are arranged at intervals on the blade shafts, a circular through hole is opened in the middle of the blade shafts, and a second spacing ring is arranged between two adjacent blade shafts.

[0019] The above technical solution is adopted, in which a second spacer ring is provided between the knife shafts to space them apart, thereby preventing the knife shafts from being squeezed and worn against each other.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The spacer ring of the utility model increases the distance between the blade bodies so that the staggered blades will not work in close contact, which can prevent the blade bodies from being squeezed and worn. The screw can be rotated to adjust the distance between the two rotating shafts, which can be adjusted according to the thickness of the paper, which can prevent paper jams or paper curling during use and improve the paper shredding efficiency.
