Abstract

The invention relates to a card smashing machine. The card smashing machine comprises a transmission assembly and a cutter shaft assembly; the cutter shaft assembly comprises two cutter shafts which are arranged in a spaced manner in parallel, and each cutter shaft is provided with a plurality of annular space rings and a plurality of annular blades with cutter noses; the position, between every two adjacent annular blades, on each cutter shaft is provided with one annular space ring, so that gaps are reserved between the adjacent annular blades; a groove is formed in the outer annular wall of each annular space ring in the circumferential direction of the annular space ring, the cutter noses of the annular blades on one cutter shaft extend to the corresponding grooves of the annular space rings on the other cutter shaft, and the cutter noses and the grooves are distributed in an adjoining manner; a discharging opening of the transmission assembly is formed above the gap between the opposite inner sides of the two cutter shafts; and when the card smashing machine is used, the two cutter shafts reversely rotate to the opposite inner sides, and the annular blades are driven to conduct cutting smashing on cards entering the position between the two cutter shafts. A groove is formed between every two adjacent annular blades, the top ends of the cutter noses are closely arranged along the grooves, the distances between the cutter noses and the corresponding cutter shafts can be reduced, and the diameter of the cutter shafts can be increased under the same conditions.

Description

technical field [0001] The invention relates to the technical field of card crushing equipment, in particular to a card crushing machine. Background technique [0002] In modern society, bank cards are widely used, and there are countless types of commercial banks. However, the recycling and destruction of waste bank cards is an extremely complicated task. Because the material of bank cards is relatively hard, incineration will cause serious problems. environmental pollution problems; facing the same problem are CDs, SD cards, circuit boards, etc. When the above products are recycled and destroyed, they also need to be cut into fragments or even particles; The operating principle of the paper shredder is that a large number of cutting blades and spacer rings are placed on the rotating knife shaft, and the two parallel and relatively rotating knife shafts are driven by a motor and a transmission gear set.

[0002] In modern society, bank cards are widely used, and there are countless types of commercial banks. However, the recycling and destruction of waste bank cards is an extremely complicated task. Because the material of bank cards is relatively hard, incineration will cause serious problems. environmental pollution problems; facing the same problem are CDs, SD cards, circuit boards, etc. When the above products are recycled and destroyed, they also need to be cut into fragments or even particles; The operating principle of the paper shredder is that a large number of cutting blades and spacer rings are placed on the rotating knife shaft, and the two parallel and relatively rotating knife shafts are driven by a motor and a transmission gear set. cut into thin strips

Because the card is thicker and harder than ordinary paper, the card cannot be shredded by a general shredder. The existing knife shaft assembly, due to the setting of the spacer, makes the tip of the knife between the outer edge of the spacer. In addition, there is a large gap between the cutter shaft and the cutter shaft, resulting in a relatively small diameter of the cutter shaft under the same conditions, which is easy to cause the cutter shaft to break, and the structure is complex and difficult to assemble
