DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0023] like Figures 1 to 5 As shown, an automatic feeding device for a shredder includes a bracket 1. When in use, the bracket 1 is mounted on the top side of the shredder by bolts or screws. The top of the bracket 1 is fixedly connected to a feed shell 2. The feed shell 2 is U-shaped and tilted, so that the shredded paper on the feed shell 2 can move downward better. The bottom end of the feed shell 2 corresponds to the position of the shredder feed port. The schematic diagram is shown in FIG. Figure 3As shown, a baffle can be set on the top side of the shredder so that the baffle and the feed shell 2 are symmetrically distributed about the feed port of the shredder, so that the paper on the feed shell 2 can smoothly enter the interior of the shredder. A plurality of mounting slots 3 are opened on one side of the feed shell 2, and the plurality of mounting slots 3 are evenly distributed at the bottom position of one side of the feed shell 2. One side of the feed shell 2 is fixedly connected to a motor seat, and a motor 4 is fixedly installed on one side of the motor seat. The output end of the motor 4 is fixedly connected to a rotating shaft 5, and one side of the feed shell 2 is fixedly connected to a stable seat. The end of the rotating shaft 5 away from the motor 4 is rotatably connected to the stable seat through a bearing, which can ensure the stability of the rotating shaft 5 during rotation. A plurality of feed rollers 6 are fixedly connected to the outer surface of the rotating shaft 5. A baffle structure 7 with adjustable position is provided on the feed shell 2. The side of the feed shell 2 away from the motor 4 is fixedly connected to two mounting blocks 8. The two mounting blocks 8 Symmetrically distributed on one side of the feed shell 2, one side of the two mounting blocks 8 are rotatably connected to a rotating plate 9, and the opposite side of the two rotating plates 9 is rotatably connected to a limiting roller 10. A fixing structure 11 for fixing the rotating plate 9 is provided on the feed shell 2, and one side of the two rotating plates 9 is fixedly connected to a fixed socket 12. When performing a large number of paper shredding operations, more paper stacks are stacked together and put into the interior of the feed shell 2, and the motor 4 is started to rotate the rotating shaft 5. At this time, several feed rollers 6 will rotate and drive the paper at the bottom of the feed shell 2 to move downward and enter the interior of the shredder for shredding operation. After a part of the paper enters the shredder, the paper at the top will move downward and continue to fit with the bottom side of the inside of the feed shell 2. At this time, the feeding operation is continued through the feed roller 6, so that the feeding operation can be automatically performed.

[0024] As an optional technical solution of the present invention, the baffle structure 7 includes a limiting groove 701, a locking threaded rod 702, a locking nut 703 and a baffle 704. The two symmetrical sides of the feed shell 2 are provided with a limiting groove 701, the interior of the two limiting grooves 701 are slidably connected with the locking threaded rod 702, the outer surfaces of the two locking threaded rods 702 are threadedly connected with the locking nut 703, and the opposite end of the two locking threaded rods 702 is fixedly connected with a baffle 704, which can block a part of the paper through the baffle 704, and there is a space between the bottom side of the baffle 704 and the feed shell 2. The gap allows the paper to move downward through the gap between the bottom side of the baffle 704 and the feed shell 2, and the amount of paper moving downward is limited through the gap. Before the shredding operation, the baffle 704 is moved according to the number of papers that the shredder can shred at one time. At this time, the locking threaded rod 702 drives the locking nut 703 to move, and the baffle 704 is adjusted to a suitable position according to actual conditions, thereby adjusting the distance between the bottom side of the baffle 704 and the feed shell 2, and then the locking nut 703 is rotated to make it fit tightly with the feed shell 2, thereby fixing the baffle 704 in a suitable position.

[0025] As an optional technical solution of the present invention, the fixed structure 11 includes a support plate 1101, a fixed spring 1102 and a fixed insertion rod 1103. One side of the bracket 1 is fixedly connected to the support block 1101, and one side of the support block 1101 is fixedly connected to the fixed spring 1102. One end of the fixed spring 1102 is fixedly connected to the fixed insertion rod 1103 with a T-shaped cross-section. When there is no need to shred a large number of papers, the fixed insertion rod 1103 is inserted into the inside of the fixed insertion hole 12, and the rotating plate 9 is located outside the feed shell 2, and the direction of the rotating plate 9 and the feed shell 2 is parallel to each other. When it is necessary to shred a large number of papers, after placing the papers inside the feed shell 2, pull the fixed insertion rod 1103 to separate it from the fixed insertion hole 12. At this time, the rotating plate 9 can rotate so that the limiting roller 10 overlaps the upper surface of the stacked papers. At this time, the limiting roller 10 can prevent the papers from being scattered, and can prevent the papers from being separated from the feed shell 2 due to external wind force, etc.

[0026] As an optional technical solution of the present invention, the number of feed rollers 6 corresponds to the number of mounting grooves 3 , and the feed rollers 6 are located inside the mounting grooves 3 .

[0027] As an optional technical solution of the present invention, the baffle 704 is located inside the feed shell 2, the length of the baffle 704 is adapted to the width of the internal size of the feed shell 2, and the baffle 704 is slidably connected to the feed shell 2, so that the baffle 704 can move smoothly.

[0028] As an optional technical solution of the present invention, the position of the limiting roller 10 corresponds to the feed shell 2, and the length of the limiting roller 10 is smaller than the width of the internal dimension of the feed shell 2, so that the limiting roller 10 can smoothly enter the interior of the feed shell 2.

[0029] As an optional technical solution of the present invention, a portion of the fixed plug rod 1103 is located inside the fixed spring 1102, the fixed plug rod 1103 passes through the support plate 1101, the fixed plug rod 1103 is slidably connected to the support plate 1101, the fixed plug rod 1103 corresponds to the position of the fixed socket 12, and the minimum diameter of the fixed plug rod 1103 is adapted to the diameter of the fixed socket 12, so that the fixed plug rod 1103 can be smoothly moved and inserted into the interior of the fixed socket 12

[0030] An automatic feeding device for a paper shredder, the working principle is as follows:

[0031] 1) Move the baffle 704. At this time, the locking threaded rod 702 drives the locking nut 703 to move, and adjust the baffle 704 to a suitable position according to actual conditions;

[0032] 2) Rotate the locking nut 703 to make it fit tightly against the feed shell 2 and fix the baffle 704 in the appropriate position;

[0033] 3) Pull the fixed rod 1103 to separate it from the fixed hole 12. The rotating plate 9 can now rotate, so that the limiting roller 10 overlaps the upper surface of the stacked paper sheets, and the paper at the bottom contacts the feed roller 6.

[0034] 4) Start the motor 4 to rotate the shaft 5. At this time, several feed rollers 6 will rotate and drive the paper at the bottom of the feed shell 2 to move downward and enter the interior of the shredder for shredding. After a portion of the paper enters the shredder, the paper at the top will move downward under the action of the limit roller 10 and its own gravity and continue to contact the feed roller 6. At this time, the feeding operation continues through the rotation of the feed roller 6.

[0035] In summary, the automatic feeding device for the shredder can automatically perform the feeding operation through the coordinated arrangement of the feed shell 2, the mounting slot 3, the motor 4, the rotating shaft 5, the feed roller 6, the baffle structure 7, the mounting block 8, the rotating plate 9 and the limit roller 10. When a large amount of paper needs to be shredded, the paper only needs to be placed on the feed shell 2, thereby eliminating the need for the operator to manually place the paper next to the shredder, reducing the labor intensity of the operator, making the entire shredding operation simpler, improving the efficiency of shredding, and being able to adjust the paper size according to the actual situation during use. The position of the baffle 704 is adjusted according to the situation, so that the automatic feeding device can automatically transport papers of thicker thickness, thereby improving the practicality of the automatic feeding device. Through the coordinated arrangement of the rotating plate 9, the fixed socket 12, the support plate 1101, the fixed spring 1102 and the fixed insertion rod 1103, the rotating plate 9 can be fixed in a horizontal state when performing a shredding operation on a smaller amount of paper, avoiding the contact between the limiting roller 10 and the smaller amount of paper. The limiting roller 10 is only used when shredding a larger amount of paper, thereby better performing shredding operations on smaller and larger amounts of paper.
