Automatically starting paper cutter

Abstract

The automatic paper cutter includes a paper cutting passage for the paper to be cut to pass through; a paper cutting mechanism; a power supply to provide the needed power for cutting paper; a trigger in the inlet of the paper cutting passage to be moved by the inserted paper to be cut; a delay unit to produce some resistance after delay for some time; a link rod between the trigger and the delay unit to produce motion; a switch connected to the power supply and contacted with the first part of the link rod to change over for on-off by responding the triggering of outer force and the interruption of the resistance of the delay unit.

Description

(1) Technical field [0001] The invention relates to a paper shredding device, in particular to an automatically activated paper shredding device. (2) Background technology [0002] The paper shredder is an indispensable business machine in the office. Please refer to Fig. 1, which is a partial structural schematic diagram of a conventional automatic start paper shredder. It can be clearly seen from the figure that the housing 10 has a A plurality of disc blades 111, trigger 12, push rod 13, shrapnel 14, gear set 15, delay cam 151, switch 16 and motor 17 on 11, when the paper to be shredded is sent into a plurality of disc blades 111 When the shredded paper is in the passage, the paper will push the trigger 12 and then drive the push rod 13 to rotate (rotate clockwise in the figure) and be in an upward position, which is used to push up the shrapnel 14 and cause the switch 16 to be turned on to make the motor 17 starts to run, and then drives a plurality of disc blades 111 o...

Problems solved by technology

[0003] However, because the trigger 12 uses the rather long push rod 13 to resist the rise of the shrapnel 14, if the push rod 13 is bent and deformed, it will easily cause the shrapnel 14 to rise insufficiently and cause the automatic start function to fail, seriously affecting Normal operation of the paper shredder

The applicant once proposed a solution for completely shredding paper in the Taiwan New Patent Application No. 83206408 (U.S. Patent No. 5984215), but because the actuator 22 is completed on the disc blade 211 with a gap in the straight shredding paper machine (see figure 2 As shown), for the paper shredder that has gradually become the mainstream (see image 3 As shown), since there is no space between the blades 311 for setting the actuator, the above technology cannot be directly applied to realize the functions of automatic start and complete paper shredding
