Problems solved by technology

[0003] When the current paper shredder is in use, paper jams often occur due to the inclined paper loading and the residual shredded paper in the blade. However, the circuit of the paper shredder is still connected at this time, so that the The continuous operation of the power mechanism will make these power mechanisms in an overload state, which will cause the temperature of these power mechanisms to be too high, causing the circuit voltage in the shredder to suddenly increase, which will easily cause damage to the circuit of the shredder and paper shredding. The phenomenon of machine fire damage occurs, thereby causing economic losses

Embodiment 1

[0024] refer to Figure 1-2 , a circuit protection mechanism for paper jams in office shredders, comprising a housing 1, a mounting plate 2 is fixedly connected to the inner bottom of the housing 1, a fixing plate is fixedly connected to the upper end of the mounting plate 2 symmetrically, and the inner wall of the housing 1 is connected to the side of the fixing plate The wall is symmetrically fixedly connected with a fixed cylinder 3, and the inner wall of the fixed cylinder 3 is fixedly connected with a contact plate 4, and the upper end of the housing 1 is slidably connected with two conductive plates 5 that are attached to the contact plate 4. Further, the contact plate 4 is in the form of The arc shape can be in close contact with the side wall of the conductive plate 5 when the side wall of the contact piece 4 protrudes outward, increasing the stability of the conductive plate 5 after electrification.

[0025] The lower end of the mounting plate 2 is provided with a bar...

Embodiment 2

[0034] refer to image 3 , different from Embodiment 1, the upper end of the housing 1 is fixedly connected with a warning light 22, the inner top of the cavity 13 away from the memory spring 15 is embedded with a second conductive strip 21, the warning light 22, the conductive block 14, the second conductive strip Bar 21 is connected in series with external power supply.

[0035] In this embodiment, when the memory spring 15 is elongated so that the conductive block 14 continues to slide and contacts the second conductive strip 21, the circuit on the alarm lamp 22 is connected at this time, and then the alarm lamp 22 emits an alarm sound, which is convenient for the user to timely repair the broken wire. The faults in the paper machine are dealt with to prolong the service life of the paper shredder.

Abstract

The invention discloses a circuit protection mechanism for paper jamming of an office paper shredder. The circuit protection mechanism for paper jamming of the office paper shredder comprises a shell, a mounting plate is fixedly connected to the inner bottom of the shell, and fixing plates are symmetrically and fixedly connected to the upper end of the mounting plate; fixing cylinders are symmetrically and fixedly connected to the inner wall of the shell and the side walls of the fixing plates, and contact pieces are fixedly connected to the inner walls of the fixing cylinders; two conductive plates attached to the contact pieces are slidably connected to the upper end of the shell; and strip-shaped cavities are formed in the lower ends of the mounting plates, and the inner walls of the fixing cylinders are fixedly connected with the inner walls of the strip-shaped cavities through connecting pipes. According to the circuit protection mechanism for paper jamming of the office paper shredder, a memory spring extends to push a conductive block to slide, so that the conductive block is separated from a first conductive strip, a circuit on a spiral coil is disconnected, a magnetostrictive rod is contracted, two sliding plates are driven to get close to each other, the pressure in the fixing cylinders is reduced, the contact pieces are driven to protrude inwards to be separated from conductive plates, therefore, a circuit on the paper shredder is disconnected, automatic shutdown of the paper shredder after a fault occurs is ensured, and the paper shredder is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of office equipment, in particular to a circuit protection mechanism for paper jams of office shredders. Background technique [0002] Paper shredders are office equipment often used in offices. They use blades and paper combs to destroy and shred unnecessary confidential documents, so as to prevent economic losses caused by the outflow of important documents. [0003] When the current paper shredder is in use, paper jams often occur due to the inclined paper loading and more shredded paper remaining in the blade. However, the circuit of the paper shredder is still connected at this time, so that the The continuous operation of the power mechanism will make these power mechanisms in an overload state, which will cause the temperature of these power mechanisms to be too high, causing the circuit voltage in the shredder to suddenly increase, which will easily cause damage to the circuit of the shredder, and pa...
