The content described in this section merely provides background information on the present invention and does not constitute the prior art.

In general, among various household wastes, including food, used in daily life, recyclable waste is usually enclosed in a garbage bag with a certain standard called a volume-rate bag at home, transported to a landfill, and then recycled as an industrial energy source. do.

In order to recycle such household waste, it is first crushed through a crushing process, and then the waste is sorted and removed through a sorting method such as magnetic force or other screens and converted into a recyclable state.

Prior to that, the garbage bag input to the crushing process is opened one by one manually by the operator for classification and recycling of garbage and put into the crusher, or a crushing operation of tearing the garbage bag by the crusher is required.

However, in the conventional shredding machine, after breaking the garbage bag, the debris of the garbage bag or the vinyl or tissue contained therein is wound around the cutting blade or caught in the groove between the cutting blade and the drum, thereby preventing malfunction or failure of the crushing machine. There were problems that caused it.

In addition, if a large amount of debris from the garbage bag as described above is wound on the cutting blade, the cutting blade is blocked and not functioning properly. There were a lot of disruptions.

Therefore, it is required to develop a charging device capable of solving the problems of the conventional charging device as described above.

The problem to be solved by the present invention is to supplement the above-mentioned disadvantages of the prior art, and the object of the present invention is as follows.

As a result, before breaking, the straight part guides the breaking target to the cutting point, and when the supply blade temporarily supports the breaking target during breaking, the breaking blade cuts the breaking target, and after breaking, along the surface of the curved part By allowing the breaking object (including foreign substances such as strings) to be discharged to the bottom, the curling phenomenon of the string on the cutter can be suppressed.

In addition, the second surface may have a slope of 45 degrees or more with respect to the first surface so that foreign substances such as strings are caught at the cutting point.

Furthermore, the supply blade may be detachable from the supply shaft so that the number and spacing of the supply blades provided on the supply shaft can be adjusted according to the size and quantity of the breaking object.

Meanwhile, the first driving unit may rotate in one direction, and the second driving unit may rotate in the other direction to prevent string curling on the supply shaft and the breaking shaft.

According to another embodiment of the present invention, the first driving unit stops driving for a certain time after the end of a series of breaking cycles so as to remove the dried string and remove the material caught between the supply shaft and the breaking shaft. and the second driving part rotates in opposite directions, and the first driving part and the second driving part rotate in opposite directions again.

At this time, the first surface may have a slope formed by engraving from the width of the blade in order to improve the cutting force.

In addition, the first surface may have a sawtooth shape to improve cutting force.

Additional solutions of the present invention will be set forth in part in the description that follows, and in part will be readily ascertained from the description, or may be learned by practice of the invention.
