Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] Such as Figure 3-Figure 5 As shown, a paper shredder single blade assembly includes a rotating shaft 8 and a plurality of single blades 9. The production of the single blades 9 is first stamped into a blade blank by a 45# steel plate with a thickness of 2.33mm, and the blank contains It includes a disc 1 and six unformed blades 2 circumferentially arranged on the disc 1, and then the unformed blades 2 are ground to form them. Specifically, the angle α of the ground blades 2 is 35° °, the disc 1 includes a locking hole 3 for locking the rotating shaft, and the single blade 9 is spirally distributed and sleeved on the single blade 9 through the locking hole 3 .

Abstract

The invention discloses a single blade assembly of a paper shredder. The single blade assembly comprises a rotating shaft and a plurality of single blades. Each single blade comprises a circular piece and a plurality of cutting edges arranged on the circular piece in the circumferential direction. Each circular piece comprises a clamping and connecting hole used for clamping and connecting the rotating shaft. The single blades are coaxially connected to the rotating shaft in a sleeving manner through the clamping and connecting holes. An interval is arranged between every two adjacent single blades. According to the single blade assembly of the paper shredder, the single blade arrangement is adopted in the blades of the single blade assembly; and compared with the traditional double-blade arrangement, the technology is simple, cost is low, the manufacturing speed is high, and the phenomenon of paper clamping cannot happen.

Description

technical field [0001] The invention belongs to the field of paper shredder accessories, in particular to a paper shredder single blade assembly. Background technique [0002] Such as figure 1 and figure 2 As shown, the traditional paper shredder blades generally have a double-blade structure. Specifically, the two blades are arranged in mirror images and riveted to each other, and the blade angle of the single blade of the paper shredder is 36°. The paper shredder of this structure The single blade has the following disadvantages: the processing technology is complicated, the cost is high, and the production efficiency is low. Moreover, when the previous double blades work, the paper will be jammed between the two blades, which will cause paper jamming. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is to solve the problems of complex processing technology, high cost, low prod...
