Shredder

This creation is related to a shredder, especially a shredder that can shred materials.

According to the current packaging or fixing operations, belts, such as iron belts, PP belts or PET belts, are often used. After use, they are too large and difficult to recycle. Therefore, they will be cut or broken by a shredder. The cutting machine is mainly provided with a cutting device on a machine table, and the machine is provided with a feeding device on one side of the cutting device, and the feeding device is provided with a feeding port, whereby the breaking When the machine is in use, it is mainly to put a material into the inlet, and introduce one end of the material into the cutting device through the feeding device for cutting, and the material can be cut or broken to finish homework.

However, although the above-mentioned crushing machine can provide the function of crushing or cutting the material, the belt body must be continuously hand-held by the user and fed into the cutting device through the feeding device for cutting, because the feeding port is open It is easy for the operator to insert his hand into the material inlet by mistake during use, or to extend his hand into the material inlet because the belt is pulled by the cutting device, and is cut by the working blade. The cut pieces of the belt body may be sprayed out from the feeding device, and there is a problem of insufficient safety. In addition, the repairing operation of the damaged cutting device requires considerable time to replace. Therefore, the creator of this case After observing the above-mentioned shortcomings, it is believed that there is a need to improve the existing crushing machine, and this creation was born.
