Description

  The present invention relates to a shredder for crushing paper and CD, and in particular, has an independent tool set for crushing paper and an independent and short tool set for crushing CD. , Each relates to a shredder that pulverizes paper and CD.

As shown in FIG. 1 and FIG. 2, the known shredder is composed of a shredder port 100 and two sets of sword tools 200, which can crush only paper and cannot crush CD pieces and the like. . Some of the shredders are provided with a CD slot, but even if there are two insertion slots, the tool is used jointly, so the blade is burdened, the tool is easily damaged, and the life of the shredder is increased. It will be shortened.

The present invention aims to provide a shredder that pulverizes paper and CD, and to improve the known problems.

According to the present invention, the shredder for crushing paper and CD is provided with two independent cylindrical sword sets on the side of the known shredder sword set, and two shredder swords on the bottom seat. And, two sets of sword tools having a crest are placed on the surface, and are moved by a motor and a speed reducer, and two different sets of sword tools crush paper and CD pieces, respectively.

  Each independent tool set ensures the service life of the crusher, and the CD piece tool set is shorter than the paper tool set, saving costs.

As shown in FIGS. 3 and 4, the shredder of the present invention includes elements such as an upper lid 1, a bottom seat 2, a motor 3, a speed reducer 4, and two sets of tool sets 5 and 6.

The top end of the top lid 1 has a paper inlet 11, a CD piece inlet 12, and a switch 13 (shown in FIG. 3), and the bottom end of the top lid 1 fixes an integrated circuit board, electric wires, and various circuit elements. Yes. The bottom seat 2 has a motor 3, a speed reducer 4, and two sets of sword tools 5 and 6, and the motor 3 is connected to an integrated circuit of the upper lid 1 and a switch by electric wires. The motor 3 drives the speed reducer 4 to rotate. The speed reducer 4 is a speed reduction mechanism composed of a small number of gears. The main shaft 31 of the motor 3 is in axial contact with the gear set of the speed reducer 4, and referring to FIGS. 5 and 7, the gear set of the speed reducer 4 is The gear 41 is swung by the main shaft 31 of the motor 3, the small gear 42 coaxial with the gear 41 is swung by rotating the large gear 43, and the small gear 44 coaxial with the large gear 43 is another one. The large gear 45 is swung and rotated, and a sword gear 46 coaxial with the large gear 45 is swung and rotated by a pair of swords 51 of the sword group 5, and the sword gear 46 is also another sword. The gear 47 is swung and rotated, and this sword gear 47 swirls and rotates another sword 52.

The above-mentioned sword gear 47 rotates the articulated gear 48 to rotate, and the articulated gear 48 oscillates to rotate the other gear 49 to rotate the other gear 49 coaxially with the gear 49. The gear 491 moves and rotates another sword gear 492 on the side, and the two sets of gears 491 and 492 of the sword set 6 respectively band the other stool 61 and 72 of the sword set 6. Move and rotate. The gear sets are respectively in axial contact with the shaft rods of the tools 5 and 6, and the two gear sets 5 and 6 are rotated and rotated by the speed reducer 4. As shown in FIG. 6, the tool set 5 is a circular shredder sword 51, 52 having two sets of spine 511, 521, which are crossed with each other. As for the distance between the shredder swords 51 and 52, the paper guiding piece 53 is mounted, and the paper A is inserted from the paper inlet 11 at the top end of the upper lid 1 and applied to the shredder. As shown in FIG. 4, the CD piece sword tool set 6 is shorter than the paper sword tool set 5, thereby reducing the production cost.

Referring to FIG. 8, the other side of the sword tool set 6 includes two sets of cylindrical sword tools 61 and 62 that support each other. The surface of the cylindrical sword tools 61 and 62 has a crest, and the CD piece B Is inserted between the blades 61 and 62 from the CD piece inlet 12 at the top end of the upper lid 1 to crush the CD piece B.

As described above, the shredder for crushing paper and CD according to the present invention accommodates a paper and CD crushing device, which is a separation type, in the bottom seat, and is connected by a connecting gear. Paper and CD pieces can be inserted and the paper and CD pieces can be crushed respectively, and confidential documents and confidential contents are not leaked. Also, the CD piece sword set is shorter than the paper sword set, thereby reducing production costs.

  In the present invention, preferred embodiments have been disclosed as described above, but these are not intended to limit the present invention in any way, and any person who is familiar with the technology can use various methods within the spirit and scope of the present invention. Therefore, the protection scope of the invention is based on the contents specified in the claims of the utility model.
