Background technique

Today, with the rapid development of knowledge, people's awareness of confidentiality is getting stronger and stronger. In daily life or work, there is often a need for document paper to be destroyed, thereby preventing others from obtaining the information recorded on the document. Correspondingly, all kinds of discarded paper technical materials are smashed and then thrown away as garbage. Different shreddering methods are suitable for different occasions. If it is a general office, it can be selected in the form of segments, granules, filaments and strips. However, if you use some occasions with high security requirements, you must use foam. Therefore, various shredders are widely used in the office. The shredder mainly uses a shredder blade that is fixed in groups on two parallel and relatively rotating cutter shafts. When the two cutter shafts rotate simultaneously, the waste paper is squeezed, thereby utilizing the shredder blades on the cutter shaft. Cut the waste paper into fine paper strips or granules for confidentiality purposes. However, the paper at the end of the shredder mechanism often cannot be effectively broken into small particles, and the confidentiality is not good. For this reason, the prior art has developed a shredder which is made up of transverse shredders. The mechanism and the longitudinal shredder mechanism are composed. The transverse shredder mechanism can be a spiral cutter formed by a spiral knife and a fixed knife, or a cutting tool formed by a movable knife and a static knife. However, the spiral cutter is not only costly, but also has a high cost. Moreover, the confidentiality of shredded paper is still not good, although the cost of the cutting tool is low, but the paper is laborious. Therefore, there is an urgent need for a shredder that is labor-saving and low in cost.

This solution allows any one-sided blade to be worn and repaired by replacing the worn blade with low maintenance costs.

Referring to Fig. 8d, the working principle of the longitudinal shredder mechanism 20 of the present invention will be described. When the shredder is started, the driving mechanism 14 drives the two shredders 11 to rotate relative to each other, and the corresponding knife edge surface 222 of the two side cutting edges 221 of the two shredder blades 11 cooperates. The paper is cut, and the paper is longitudinally cut into a plurality of longitudinal strips 161 along the knife edge surface 222, and the blade end surface of the one side edge 221 of the upper paper shredder cutter 11 cuts the longitudinal strip 161 along the corresponding cutting side (the one cut Side) downwardly into the blade gap of the lower shredder tool 11, the end face of the unilateral blade 221 of the lower shredder tool 11 is the upward strip 161 along the corresponding cutting side (the other side to be cut) upward In the blade gap of the upper shredder cutter 11, the longitudinal strip 161 is inclined to fall into the gap 23 formed by the two shredders 11 interlaced, especially under the action of gravity, falling into the support surface 213 of the gap 23. Inside, it facilitates the export of the longitudinal strip 161, which is not easy to jam.
