[0010] However, the disadvantage of the structure shown in FIG. 2 is that the spring 29 usually produces elastic fatigue after being used for a long time, so that the product reliability of the shredder mechanism 20 will obviously be reduced as the usage time of the shredder mechanism 20 increases. That is, t

Embodiment Construction
[0064] A preferred embodiment is given below to illustrate the present invention, but those skilled in the art know that this is only an example and is not intended to limit the invention itself.
[0065]Please refer to FIG. 3(a) and FIG. 3(b), which are respectively a top view and a side view of a preferred embodiment of the present invention. In Fig. 3 (a), sheet processing mechanism 30 (for example, can be paper shredding mechanism or clam protection mechanism etc.) comprises: sheet feeding channel 31, a frame 32 with hollow area 320, two Sliding guide blocks 331 , 332 , a fixed round rod 34 with two abutting tops 3411 , 3412 , a movable round rod 35 with another two abutting tops 3511 , 3512 , two coil springs 361 , 362 and two thickness sensing devices 371 , 372 .
[0066] In this structure, the frame 32 is arranged in front of the entrance of the sheet-feeding channel 31, so that a sheet (not shown, such as paper) is fed into the sheet through the hollow area 320. In th...

The invention relates to a floating-type flap thickness detecting device. The device comprises two guide grooves, which are respectively arranged on lateral plates of two sides of a flap processing mechanism; two sliding guide blocks, which are respectively combined with the two guide grooves; an elastic abutting device, which is composed of a first abutting component and a second abutting component arranged respectively in modes of firm installation and sliding installation between the two siding guide blocks; at least one thickness sensing device, which is arranged on a side of one of the two sliding guide blocks and close to the second abutting component. When the second abutting component generates a thickness displacement in response to the different thicknesses of the flap, a thickness detection signal is generated because of the synchronization action of at least one thickness sensing device; and a free gap lies between one of the sliding guide blocks and the correspondingly combined guide groove thereof, when the front position of the flap carries out a processing action in a channel for the flap to feed in and relatively causes the swing effect in the rear position of the flap, the sliding blocks can synchronically perform displacement in the guide grooves so as to absorb the swing effect.
Description
technical field [0001] The invention relates to a sheet thickness detection device, in particular to a floating sheet thickness detection device applicable to a sheet processing mechanism. Background technique [0002] In today's various paper shredding mechanisms, scanning mechanisms, or shell protection mechanisms, it is often faced with the problem of different thicknesses of the processed sheet objects (such as paper, credit cards, photos, etc.), once these objects to be processed When the thickness exceeds the specifications that the processing mechanism can allow, abnormal phenomena such as blockage or suspension of operation usually occur. Waiting until now for the user to remove the obstacle is often difficult to deal with, and even has to be sent for repair, which will only increase the inconvenience in use. [0003] In order to solve the above problems, various solutions have been proposed in the industry. For an example of existing shredding technology, see fig...
