Problems solved by technology

However, the structure of the existing paper shredder 100 can only detect the thickness of objects to be shredded with a single size. Allowing shredded paper thickness as a standard for larger width items to be shredded will cause paper jams or damage to the shredder cutter set 107

Embodiment Construction

[0052] In view of the defects in the prior art, the present invention provides a detection mechanism capable of detecting the width of the object to be shredded, and the allowable thickness of the object to be shredded can be known according to the width of the object to be shredded. Please refer to FIG. 2 , which is a structural schematic diagram of a preferred embodiment of the detection mechanism for the width and thickness of the object to be shredded in the paper shredder of the present invention. The detection mechanism 200 includes a shredded paper channel 201, a first width sensor 202, a second width sensor 203, a third width sensor 204, a thickness detection module 205 and a control unit (not shown in the figure). The passage 201 is used to allow the objects to be shredded (not shown in the figure) to pass through for shredding. The first width sensor 202 is located on the shredding passage 201, and the second width sensor 203 is arranged on the first width sensing On...

Abstract

The invention relates to a mechanism of a shredder for detection of the width and the thickness of an object to be shredded, which comprises a shredding channel, a first width sensor, a second width sensor, a third width sensor, a thickness detection module and a control unit, and the thickness detection module comprises a propping element, a thickness detection element and two groups of thickness sensors. The mechanism adopts the first width sensor, the second width sensor and the third width sensor to detect the width of the object to be shredded, so as to decide to use which thickness sensor to detect whether the thickness of the object to be shredded is more than the allowed thickness corresponding to the width of the object to be shredded. Therefore, the invention can detect the width and the thickness of the object to be shredded more accurately, thereby achieving the effect of improving the protection mechanism of the shredder.

Description

technical field [0001] The invention relates to a detection mechanism, in particular to a detection mechanism for the width and thickness of objects to be shredded in a paper shredder. Background technique [0002] When the shredder shreds the object to be shredded, if the thickness of the object to be shredded is too thick, such as paper or CD, and the thickness exceeds the allowable range of the shredder, paper jams and the like will occur. In order to prevent the above-mentioned things from causing the paper shredder to fail to operate normally, or even damage the paper shredder, a common practice is to specially set a paper thickness trigger device in the paper shredder to detect whether the thickness of the object to be shredded exceeds that of the paper shredder. normal working range. [0003] Please refer to FIG. 1 , which is a schematic diagram of a conventional shredder with a paper thickness triggering device. In the shredder 100 , the paper inlet 101 is disposed...
