Description

Crushing cutter and crusher Technical Field The utility model relates to the technical field of plastic crushing, in particular to a crushing cutter and a crusher. Background A plastic crusher is an apparatus for crushing plastic waste or plastic products into small particles, widely used in the plastic recycling industry and waste treatment. The working principle is that the plastic materials are crushed by mechanical force, so that the volume of the plastic materials is reduced, and the plastic materials are convenient for further treatment or reutilization. When the traditional plastic crusher is used for processing and crushing plastics, firstly, the plastics are put into a feed port, after entering the inside of the crusher, the plastics fall into a lower material frame, in the rotating process of a rotating shaft, the plastics are turned over by a knife rest on the rotating shaft, and in the turning process, the plastics can randomly fall between a movable knife arranged on the knife rest and the positioning on the material frame, the plastic materials are cut into small blocks or particles in a shearing and pressing mode through the two modes, so that the plastic processing and crushing are realized, but in the actual use process, the movable knife on the knife rest is found to be required to be subjected to position adjustment and installation, in the installation process, firstly, the movable knife is subjected to incomplete temporary fixation through a bolt, then a worker can repeatedly beat through a hammer, so that the position of the movable knife is adjusted until the position of the movable knife is matched with that of the fixed knife, and finally, the bolt is rotated, so that the movable knife is subjected to final fixation and limit, but the mode is complicated, the repeated use of a tool is required, the position of the movable knife is continuously confirmed, and in the process, the side pieces are generated, so that the crushing knife is inconvenient to use. Disclosure of Invention The utility model aims to solve the technical problems that a worker repeatedly strikes a hammer to adjust the position of a movable cutter until the position of the movable cutter is matched with that of a fixed cutter, and finally rotates a bolt to enable the movable cutter to carry out final fixed limit. The technical scheme includes that the crushing cutter comprises a rotating shaft, a cutter frame is arranged on an arc surface of the rotating shaft, movable cutters are respectively arranged around triangles of the cutter frame by means of bolts, an auxiliary device is arranged on one side of the surfaces of the cutter frames, which is located on the movable cutters, and the auxiliary device is used for pre-adjusting and fixing the installation positions of the movable cutters by means of a positioning plate and bolts. The plastic crusher has the advantages that when the crusher for plastic is used for installing and adjusting the cutter, the movable cutter is installed on the cutter frame on the rotating shaft, the movable cutter is firstly placed at the assembling position of the cutter frame, the temporary position stabilization is carried out on the cutter frame through the bolts, then the auxiliary device is operated, the movable cutter is adjusted and displaced to the matched installing position, then the bolts on the movable cutter are rotated, and the movable cutter is finally fixed and limited in position. Preferably, the auxiliary device comprises a mounting plate arranged on the tool rest, a screw rod is rotatably arranged on the surface of the mounting plate, a positioning plate is connected to the arc surface of the screw rod in a penetrating threaded manner, the section of the positioning plate is U-shaped, the surfaces of the positioning plate are positioned on two sides of the screw rod and are respectively provided with a stabilizing plate in a sliding manner, a nut is connected to the arc surface of the screw rod in a threaded manner, and the nut is positioned between the positioning plate and the mounting plate. The plastic crusher has the advantages that when the plastic crusher is used for installing and adjusting the moving knife of the cutter, the position of the moving knife can be adjusted to the installation position in a stable and aligned mode more quickly and conveniently, shaking and shifting are not easy to occur, the installation means are simplified, and the convenience of using the cutter is improved. Preferably, the auxiliary device further comprises an operation block installed at one end of the screw, and the operation block assists the rotation of the screw. The screw rod is more convenient and quick when rotating through the arrangement of the operation block, so that the positioning plate is more convenient and quick when pushing the movable knife to change and adjust the position, and the convenience of using the auxiliary device is improved. Preferably, the auxil
