Description

Sensing device for paper rated thickness at paper inlet of shredder

Technical field:

The utility model relates to the technical field of shredder products, in particular to an induction device installed at the paper inlet of the shredder and used to limit whether the paper thickness of the shredder exceeds the rated thickness.

Background technique:

Improper collection of discarded manuscript paper will bring a lot of trouble to our work, and even cause serious consequences for business safety. In the past, the method of incineration was used for collection, which not only required a site for incineration, but also caused serious air pollution. In order to change this situation, various paper shredders have come out.

The paper shredders currently used in the market usually consist of a paper scrap bucket and a paper shredder head fixed on the paper scrap bucket, wherein a paper shredding device is arranged in the head. The shredding device of the paper shredder is powered by a motor, and then a series of gears and other transmission mechanisms transmit the power to a pair of cutter shafts with shredding blades distributed on it. The shredding device is installed and positioned on the upper, In the housing composed of the lower cover, there is formed on the upper cover a slender notch 11 for the user to put the paper to be shredded into. Usually we call it the paper inlet of the shredder. Because the paper to be shredded may be scattered and has a certain thickness, in order to facilitate the user to quickly and conveniently put the paper to be shredded into the paper inlet of the shredder, the slot width of the paper inlet is generally much larger than the thickness of the paper to be shredded. It gives the user the opportunity to put paper exceeding the rated thickness into the shredder. If the paper exceeds the rated thickness, it will easily overload the shredder and damage the shredder itself. However, the existing paper shredder itself does not have a device for checking whether the shredded paper exceeds the rated thickness, so users often put in too much paper.

Utility model content:

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide an induction device for the rated thickness of the paper at the paper inlet of the shredder. Thickness, then by the utility model the shredding direction power supply of paper shredder is turned off.

In order to solve the above technical problems, the utility model adopts the following technical solution: an induction device is installed at the paper inlet to detect whether the inserted paper exceeds the rated thickness, and the induction device includes: at least one The movable part on the side wall of the channel is linked with the power switch that can cut off the work of the shredder.

A corresponding fixing part is installed on the other side wall of the passage of the paper inlet relative to the movable part. The gap between the fixed part and the movable part forms a passage for allowing paper to pass through. The fixing part can be formed by other components, and can also be integrally formed on the side wall.

The above-mentioned movable part is a cam, and the contact of the touch-press power switch located at the side of the cam is pushed by the rotation of the cam.

The cam is installed on a rotating shaft, and a torsion spring is arranged between the rotating shaft and the cam to reset the deflected cam.

Alternatively, the movable part adopts the following structure, which includes a touch bar and a spring that pushes the touch bar to protrude toward the channel, and the touch power switch is arranged at the rear end of the touch bar along the elastic direction of the touch bar.

After the utility model adopts the above technical proposal, the power supply of the paper shredder in the paper shredding direction is cut off through the power switch linked with the device. That is, when the user puts paper that exceeds the rated thickness of the shredded paper into the shredder from the paper inlet, the paper that exceeds the rated thickness will touch the sensor device, and the power switch linked with the device will be triggered to cut off the shredded paper. The direction of the power supply, so paper exceeding the rated thickness will not be able to start the shredder, so it can protect the shredder when the user puts too much paper carelessly. Compared with the current paper shredder, the utility model is safer and more reliable.

In this embodiment, the movable part 21 is a cam 211, and the power switch 3 is fixed at the rear end of the cam 211, and the contact 31 of the touch-press power switch 3 is pushed by the rotation of the cam 211 to cut off the direction of the paper shredder. power supply. The cam 211 is mounted on a rotating shaft 212 , and a torsion spring 213 is arranged between the rotating shaft 212 and the cam 211 to reset the deflected cam 211 .

A corresponding fixed part 22 is installed on the other side wall of the channel 10 of the paper inlet 11 opposite to the movable part 21 . The gap between the fixed part 22 and the movable part 21 forms a passage for allowing paper to pass through. In order to facilitate the smooth insertion of the paper 4, the fixing member 22 adopts a roller 221, which is installed on a rotating shaft 222, so that when the paper 4 is inserted, the sliding friction between the paper 4 and the fixing member 22 will become rolling friction, Reduces friction and facilitates paper insertion. In addition, the fixing part 22 can be formed by other components, and can also be integrally formed on the side wall.
