Description

A safety protection device for a paper shredder

technical field

The utility model belongs to the technical field of office appliances and specifically designs a shredder safety protection device.

technical background

A paper shredder is a commonly used office equipment. The paper inlet of the paper shredder is usually designed on the top of the body, and the paper inlet is open upward. During the use of the paper shredder, there are often hard foreign objects such as paper clips and staples. Fall into the paper entrance, or the paper entrance is blocked due to long-term accumulation of dust. When the shredder starts to rotate the internal bearing, dust or hard objects will be rolled into the entrance, causing the shredder to not work normally, and even damage the shredder in severe cases. paper machine; or because the thickness of the shredded paper is thicker, exceeding the rated thickness of the shredder, causing damage to the blade; in CN 101623664 B, a safety protection device for the paper inlet of the shredder is disclosed, including a cover plate, The safety cover, the stopper of the paper feeding channel and the elastic part, the safety cover is rotatably connected in the upper cover cover, the first end of the safety cover covers the entrance of the paper feeding channel in the upper cover cover, and the paper feeding The channel stopper is slidably arranged in the upper cover cover plate towards the paper input channel and is limited/connected to the second end of the safety cover. Ground, the stopper of the paper entry path is fixedly connected with the second end, or integrally formed with the second end, or the studs provided at the second end are limited, and the stopper of the paper entry path is located between the paper entry path and the elastic member , the safety cover is axially connected to the upper cover; although it plays a role in safety, it cannot detect hard objects and will inevitably cause damage to the shredder. , and can play a safe and secure device.

Utility model content

The main purpose of the utility model is to provide a safety protection device for shredders with simple structure, easy operation, safety and reliability.

In order to solve the above problems, the technical solution adopted by the utility model is: a shredder safety protection device, including a frame body, an inclined groove is arranged on the upper part of the frame body, a transmission wheel set is arranged on the lower part of the inclined groove, and the upper part of the inclined groove A metal detector is set, the inclined groove is a plastic product, the transmission wheel group is a runner group arranged up and down, and the metal detector is connected with a single-chip microcomputer.

An electromagnet is arranged on the inclined slot, and the electromagnet is connected with a single-chip microcomputer, and the single-chip microcomputer is connected with a paper shredder.

The upper part of the inclined groove is provided with a rotating shaft.

The utility model adopts the mode of the inclined groove so that the paper can transfer the waste paper to the working part under the action of gravity. Since the metal detector is set above the inclined groove, it can give an alarm when it detects the metal mixed in the paper, and then through the single chip microcomputer It makes it possible to stop the paper shredder, then close the metal detector by itself, and connect the electromagnet. At this time, the paper can be slowly taken out. If there is a ferrous object, it will generate a great gravitational force, so that the operator can easily find the ferrous object , then cut off and restart the shredder, and the operator can detect whether there is any metal substance through the metal detector again; since the staples and paper clips commonly used in common office sites are all iron components, they can pass through the electromagnetic iron for adsorption; the waste paper is placed in the inclined trough and passes through the metal detector and then enters the runner group, so that it can change the waste paper into an S shape and then shred it. The side becomes an elastic wheel, so that it can adapt to paper of different thicknesses, and at the same time, it can avoid the phenomenon that the wheel set is damaged due to the presence of hard objects; the inclined groove of the plastic part can not only avoid the false detection of the metal detector and its The quality is lighter, and the rotating shaft is set on it, so that it can be folded and covered to prevent dust falling; after adopting the utility model, the structure is compact, the operation is simple, and the life of the shredder is increased by more than 15%, which is worthy of popularization and application.
