Description

A stirring device for increasing the capacity of waste paper cylinder

technical field

The utility model relates to a waste paper cylinder used with a paper shredder, and in particular provides an agitating device capable of increasing the capacity of the waste paper cylinder. Through the reciprocating motion of the agitating device, the gap between shredded paper scraps is reduced to increase the capacity of the waste paper cylinder.

Background technique

As we all know, the paper shredder used for shredding paper is based on the principle that a large number of cutting blades (cutting blades) and spacers (spacers) are placed on the rotary shaft (rotary shafts), and the motor and gear box (motor and gear box) are used to ) to drive the two parallel and relatively rotating knife shafts to cut the paper into thin strips by using shear force.

According to the different mechanical cutting modes, paper shredders are divided into two types: stripe-cut shredders and cross-cut shredders. The former is to arrange the cutting blade specifications on the rotary knife The paper is cut longitudinally into long strips on the rotary knife wheel, and the blade of the latter has more than one hook-shaped blade, and the blades are arranged in a spiral shape on the rotating knife wheel, so that the paper is not only cut into strips longitudinally, but also cut horizontally into shredded paper.

Regardless of the above-mentioned straight shredder or crushing shredder, it is generally sold with a waste paper drum (basket or bin) for shredded paper; as mentioned above, the cutting tool of the shredder uses a motor And the gear device drives two parallel and relatively rotating knife shafts, which cut the paper into thin strips or fragments with shear force on the passing paper, and then fall down on the waste paper through the paper drop port at the bottom of the shredder. inside the barrel. Since the fluffy paper strips or scraps of paper are piled up in an irregular manner with a large gap between each other, it is easy to reach a paper full state. In addition, as the quantity increases, the resulting shredded paper pieces are easy to accumulate into a mountain shape under the paper drop opening, commonly known as "paper mountain (chip mountain)". When the height reaches the vicinity of the paper drop opening, it will not only prevent the subsequent shredded paper from falling down smoothly, but even cause the shredded paper to be rolled back into the gap between the blades to cause a "jam", affecting the normal operation of the shredder.

Experience has shown that as long as the user moves and presses the randomly piled up pieces of paper to make them spread out and flatten around, the space for holding the pieces of paper in the waste paper tube can be significantly increased, and the capacity of the waste paper tube can be increased. , thereby reducing the cleaning frequency of shredded paper. In particular, it is possible to avoid the failure situation that the above-mentioned paper mountain hinders the falling of the subsequent pieces of shredded paper or even causes paper jamming.

Utility model content

The main purpose of this utility model is to provide a simple pedal action that allows the user to make the agitation device flip and flatten the scraps of paper, thereby reducing the gap between the scraps of paper and increasing the capacity of the waste paper tube .

Another purpose of the present utility model is to provide a device that allows the user to flip and flatten the shredded paper scraps by the agitating device through a simple pedal action, so that the shredded paper scraps piled up into a mountain of paper can be flattened around. In order to avoid paper scraps that hinder the subsequent downward fall from being rolled back into the gap between the blades and causing paper jams.

In order to achieve the above purpose, the utility model provides an agitating device for increasing the capacity of the waste paper cylinder. A stirring device that can turn and flatten the shredded paper scraps is installed at an appropriate position of the waste paper cylinder. The device includes: The actuating part is pivotally connected to a proper position of the waste paper cylinder, so that the pivot joint serves as a fulcrum for movement; the linking part is integrated with the above-mentioned actuating part, and moves synchronously with the actuating part using the pivot as a fulcrum.

Wherein, the agitating device is arranged below the waste paper cylinder and adjacent to the bottom.

When force is applied to the actuating part to drive the linking part to reciprocate with the pivot as the fulcrum, the linking part will have the effect of flipping and flattening the scraps of paper, thereby reducing the gap between the scraps of paper and increasing the capacity of the waste paper drum.

Detailed ways

The features of the utility model can be clearly understood by referring to the drawings and the detailed description of the embodiments.

Please refer to FIG. 1 for a structural diagram of the first embodiment of the utility model, and FIG. 2 for a cross-sectional view of the first embodiment of the utility model. A stirring device for turning up and down the shredded paper scraps is provided at the position adjacent to the bottom of the waste paper cylinder, and the device is composed of an actuating part and a linking part.

In this embodiment, the actuating part is a pedal 1, and the linking part is an agitating rod 2 fixed on the pedal. Wherein the pedal 1 is connected with the waste paper cylinder 3 by a first pivot 4, so that the pivot joint forms a fulcrum.

During specific implementation, stepping on the actuating part with the feet up and down will synchronously drive the linkage part to generate up and down reciprocating motion with the pivot as the fulcrum. In other words, applying force to the pedal 1 can directly drive the stirring rod 2 to reciprocate up and down, so that the scraps of paper are continuously turned and flattened to reduce the gap between scraps of paper and increase the capacity of the waste paper drum.

Please refer to FIG. 3 for a structural diagram of the second embodiment of the utility model, and FIG. 4 for a cross-sectional view of the second embodiment of the utility model. A stirring device for turning up and down the shredded paper scraps is provided at the position adjacent to the bottom of the waste paper cylinder, and the device is composed of an actuating part and a linking part.

In this embodiment, the actuator is a pedal 1, and the linkage is a link mechanism. Wherein, the pedal 1 is connected with the waste paper cylinder 3 by the first pivot 4 so that the pivot joint forms a first fulcrum; the fixed end of the first connecting rod 21 is combined with the pedal 1, and the free end is connected by the second The pivot 41 is combined with the stroke limiting groove 221 of the second connecting rod 22, and the pivot joint forms a second fulcrum; the fixed end of the second connecting rod 22 is combined with the inner bottom edge 31 of the waste paper drum through the third pivot 42, so that The connection forms a third fulcrum, and the free end of the second connecting rod is integrated with the stirring rod 2 again.

During specific implementation, stepping on the actuating member up and down with the foot will drive the linkage member to generate up and down reciprocating motion with the pivot as the fulcrum. That is, applying force to the pedal 1 drives the first connecting rod 21 to tilt upward with the first pivot 4 as the fulcrum, so that the second connecting rod 22 respectively takes the second pivot 41 and the third pivot 42 as the fulcrum, With the upward tilt of the first connecting rod 21, it goes upward synchronously, and the agitating rod 2 produces a stirring effect on shredded paper scraps during the process of being driven upward. Repeating the above-mentioned action process can produce the effect of turning and flattening the shredded paper, thereby reducing the gap between the shredded paper and increasing the capacity of the waste paper drum.
