Shredders with Electric Press Mechanism

Technical field:

The utility model relates to the technical field of paper shredders, in particular to a paper shredder with an electric paper pressing mechanism.

Background technique:

Paper shredders are widely used. It can be used to shred paper and CDs, etc., to prevent the leakage of important information. The paper shredder includes a paper shredder head and a shredded paper barrel. The shredded paper barrel generally includes a shredded paper inner barrel and a shredded paper outer barrel. The shredded paper inner barrel is used to collect shredded debris. Since the capacity of the shredded paper inner bucket is limited, if the debris in the shredded paper bucket is too high during shredding, the debris will contact the shredded paper assembly through the paper outlet, thereby affecting the work of the shredded paper assembly. , When the debris in the shredded paper inner barrel is piled up too high, it is necessary to pour out the debris in the shredded paper inner barrel. In fact, when the debris falls into the shredded paper inner barrel from the paper outlet, each debris is loose, so it will soon make the shredded paper inner barrel form the illusion that it is full, so that the user will frequently It is very inconvenient to dump the shredded paper inner barrel.

Utility model content:

The purpose of this utility model is to provide a paper shredder with an electric paper pressing mechanism for the deficiencies of the prior art. A certain accumulation space is formed until the debris in the shredded paper inner barrel is compacted, which can reduce the number of times users dump the shredded paper inner barrel, which is very convenient.

In order to achieve the above object, the utility model adopts the following technical solutions:

It consists of a shredder head and a shredder barrel. The shredder head is composed of a shredder head top cover and a paper shredder head bottom cover. The paper shredder also includes a motor, a paper press frame, and a press The paper holder is located in the shredding bucket and is driven by a motor to move up and down in the shredding bucket, and the motor drives the paper pressing frame to go up and down to compress the paper scraps in the shredding bucket.

Specifically, a gear is installed on the output shaft of the motor, and the paper platen is fixedly connected with a longitudinal rack, and the gear meshes with the rack.

Further, a through hole is opened at the bottom of the bottom cover of the head of the shredder, and the rack is inserted into the through hole.

Furthermore, the bottom cover of the head of the paper shredder has a longitudinal limiting groove for limiting the movement of the rack.

The motor is installed in the bottom cover of the paper shredder head, and the bottom cover of the paper shredder head has an auxiliary positioning plate for auxiliary positioning of the motor.

In another specific example, a control switch for controlling the operation of the motor is installed on the upper cover of the shredder head.

Further, a paper inlet is opened on the upper cover of the shredder head.

The shredded paper bucket has a transparent window.

The paper pressing frame has a paper leakage hole, and paper dust can fall into the shredded paper barrel through the paper leakage hole.

The beneficial effect of the utility model is that a liftable paper presser is set in the paper shredder, and when the paper scraps in the shredder bucket occupy a large space, the paper presser can be driven up and down by a motor, so that the paper presser can be used to lift the The paper scraps are pressed tightly, leaving a certain space in the shredding bucket, which is convenient for the next shredding operation.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

See accompanying drawing 1-3, the paper shredder of the utility model comprises a paper shredder head, a paper shredder drum 30, and the paper shredder head is composed of a paper shredder head cover 10, a paper shredder head bottom cover 20, the paper shredder head is also provided with a shredding assembly (not shown in the figure); the paper shredder head cover 10 is provided with a paper inlet 12, and the paper to be shredded is passed through the paper inlet 12 into the shredder, the shredder head bottom cover 20 is provided with a paper outlet 23, and the paper dust formed by crushing falls into the shredding bucket 30 through the paper outlet 23;

The shredder also includes a motor 40 and a paper pressing frame 50. The paper pressing frame 50 is located in the shredding bucket 30 and is driven by the motor 40 to move up and down in the shredding bucket 30. The lifting action of the paper pressing bracket 50 can move the shredding bucket 30 The paper scraps in the shredding bucket 30 are pressed tightly, so that a certain space is vacated in the shredding bucket 30 to facilitate the next shredding operation.

In order to realize that the motor 40 drives the platen 50 up and down, the utility model adopts the following structure, a gear 41 is installed on the output shaft of the motor 40, and the described platen 50 is fixedly connected with a rack 60, the rack 60 Installed vertically and vertically, the gear 41 meshes with the rack 60. When the motor 40 works, its output shaft drives the gear 41 to rotate, and the gear 41 rotates to drive the rack 60 to move longitudinally, and the rack 60 pulls the platen Frame 50 realizes lifting.

Wherein, the rack 60 can be arranged in the shredder bucket 30 and move in the shredder bucket 30. The utility model adopts another solution: see FIG. 2, the bottom of the shredder head bottom cover 20 has a A through hole (not shown in the figure), the rack 60 is inserted in the through hole, that is, the rack 60 can move in the shredder head bottom cover 20 and the shredder bucket 30, thereby saving space.

Further, the shredder head bottom cover 20 has a longitudinal limit groove 21 that limits the movement of the rack 60, and the limit groove 21 can be used to limit the position of the rack 60 to ensure that the rack 60 moves stability.

The motor 40 can be installed in the shredder barrel 30 or the outer bottom of the shredder head bottom cover 20. The utility model adopts the scheme shown in FIG. 2, that is, the motor 40 is installed in the shredder head Inside the bottom cover 20, there is an auxiliary positioning plate 22 for assisting the positioning of the motor 40 in the bottom cover 20 of the paper shredder head. The solution of the utility model is more convenient and concise.

The shredder machine head upper cover 10 is equipped with a control switch 11 for controlling the operation of the motor 40. The operation of the motor 40 must be able to realize forward rotation and reverse rotation, so as to ensure that the rack 60 can both move upward and Moving down, the platen 50 also realizes lifting; in addition, the number of times the motor 40 rotates determines the moving distance of the rack 60, which can be pre-designed, for example, when the control switch 11 is started, the motor 40 rotates forward for a certain number of times Then stop, and then the motor 40 starts to reverse, and the motor 40 stops after a certain number of reverses. Move up to the highest point.

The shredded paper bucket 30 has a transparent window 31, through which the user can see the accumulation degree of the paper scraps inside the shredded paper bucket 30. If the paper scraps are piled up too high, the paper presser 50 can be started to work. Compress the paper scraps in the shredder bucket 30.

It should be noted that the paper pressing frame 50 has a paper leakage hole, that is, the paper pressing frame 50 itself must allow the crushed paper scraps to pass through and drop into the shredded paper barrel 30. When making the paper pressing frame 50 , the corresponding leakage hole must be designed.

The shape of the paper press frame 50 of the utility model is not limited, and can have different shapes.

The opening shape of the paper shredder applied by the utility model is also not limited.

The working principle of the utility model is:

When there is too much paper dust in the shredder barrel 30, start the control switch 11 to make the motor 40 work, the motor 40 realizes forward rotation and reverse rotation, the output shaft of the motor 40 drives the gear 41 to rotate, and the gear 41 rotates to drive the rack 60 To realize the lifting movement, the rack 60 pulls the paper pressing frame 50 up and down, and then compresses the paper scraps in the shredding bucket 30, leaving a certain space for the next shredding operation.

The utility model has the advantages of simple structure, convenient use and humanized features.
