Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 3: the paper feeding method of the paper feeding device of the paper shredder comprises the following steps: 1) inserting the bottom of the waste paper into the paper inlet 5; 2) the downward rotation of one side of the distribution wheel close to the paper is used as reverse rotation, and the reverse rotation of the distribution wheel is 0.25-3 weeks; 3) the branch dial wheel rotates positively to send a plurality of pieces of waste paper positioned at the front side into the paper shredding roller knife for shredding. The invention takes the rotation of 360 degrees as 1 week, and the rotation of 90 degrees is taken as the rotation of 0.25 week of the dial wheel.

The paper feeding device also comprises a sensor for sensing that paper is put into the paper feeding port, the bottom of the waste paper is inserted into the paper feeding port 5 in the step 1), and the sensor senses that the waste paper is inserted, and then the step 2) is carried out. The sensor can be an electric switch, such as an infrared switch or a microswitch, or other electronic components capable of detecting insertion of waste paper.

In the step 2), the cam 2 is reversed to the bottom surface of the waste paper and is positioned between the paper clamping groove 3 and the paper separating edge 2 a. This is preferred according to the present invention, and in this state, the flat surface of the cam 2 and the paper separation edge 2a function as a reverse and a stop. In this state, the transfer wheel rotates forward again, so that the waste paper on the front side can be quickly inserted into the paper clamping slot 3, and then a predetermined amount of waste paper is fed into the paper shredding roller knife to be shredded. The forward rotation is realized by rotating the distributing wheel on the side close to the paper.

In the step 3), the paper shifting wheel 4 positively rotates to drive the paper clamping groove 3 to rotate to the bottom of the front side of the waste paper, the paper on the front side of the waste paper falls into the paper clamping groove 3 under the action of self gravity, and the positively rotating paper shifting wheel 4 drives the waste paper falling into the paper clamping groove 3 to enter the paper shredding roller knife for shredding.

In the step 2), the transfer wheel rotates reversely for 0.4 weeks. For the preferred construction of the invention, the cam 2 may be reversed for a number of revolutions to ensure proper positioning of the waste paper. But the cam 2 rotates for many circles, which causes a certain waste of resources. Preferably, the cam 2 can reverse for 0.4 weeks to realize the waste paper regulation and ensure the waste paper regulation in place.

The cam 2 is a half-cam 2 structure with the diameter gradually increased, one side surface of the cam 2 is a plane 2b, and the cam 2 reversely rotates to the plane to back stop the waste paper to the paper supporting plate 1. Specifically, only the portion of the flat surface of the cam 2 that extends beyond the pick wheel 4 will act on the paper. The maximum diameter of the cam 2 is a paper separating edge 2a, and the paper separating edge 2a is connected with one end of a plane 2 b. The rotating paper separating edge 2a can rub and turn over the mutually adhered edges of the wad of paper to separate.

The paper poking wheel 4 is of a round wheel structure, and the diameter of the paper poking wheel 4 is larger than the minimum diameter of the cam 2 and smaller than the maximum diameter of the cam 2. The periphery of dialling paper wheel 4 is seted up to card paper groove 3, and the position in card paper groove 3 is relative with the plane of cam 2, and waste paper falls into card paper groove 3 and does not contact with cam 2. The structural design of the paper poking wheel 4 can meet the requirements of the cam 2 on the effect of waste paper and the effect of the paper poking wheel 4 and the paper clamping groove 3 on the waste paper.

When the plane of the cam 2 is erected near one side of the waste paper, the paper separating edge 2a is positioned above the plane. The reverse rotation of the cam 2 moves the used paper back, and the cam 2 also serves as a stop to prevent the paper from deviating from the predetermined position again. The cam 2 rotates positively to rub, turn and separate the edges of the wad of paper adhered to each other.

The cam 2 is coaxial with the paper poking wheel 4, and the motor drives the cam 2 and the paper poking wheel 4 to synchronously rotate.

The distributing wheel comprises two cams 2 and two paper shifting wheels 4, and the two paper shifting wheels 4 are positioned on two sides of the two cams 2. Is the preferred structure of the present invention.
