Description

Technical Field

[0001] The invention belongs to the technical field of waste tire processing related equipment, and in particular relates to a waste tire high-speed cutting tool assembly. Background Art

[0002] For the recycling of waste tires, the tires with larger outer diameters are usually cut and then crushed into pieces to form rubber powder particles for reuse. Waste tires are hard and tough at room temperature. They are crushed by double roller crushers or sheet cutters. The crushing efficiency is not high and the cutters are worn out. Moreover, the cutters are often an integral structure and cannot be partially replaced, which affects production efficiency and increases production costs. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a waste tire high-speed cutting tool assembly, which can perform corresponding cutting and crushing operations through the cooperation of rotating and stationary tools, facilitate the individual replacement of worn tools, and reduce maintenance costs.

[0004] The technical solution adopted by the present invention is as follows: a waste tire high-speed cutting tool assembly is arranged in a pulverizing operation chamber, a rotating shaft is arranged in the pulverizing operation chamber, the cutting tool assembly includes a fixed tool unit and a rotating tool unit that cooperate with each other to perform cutting operations; the fixed tool unit includes a fixed tool holder installed on the pulverizing operation chamber and a fixed tool body installed on the fixed tool holder; the rotating tool unit includes a fixed disk fixed on the rotating shaft, the fixed disks are arranged in sequence along the central axis direction of the rotating shaft, and an installation space is formed between the fixed disks; a long tool is fixed in the installation space and symmetrically distributed along the diameter direction of the fixed disk, and the distal end of the long tool that rotates with the rotating shaft extends radially out of the installation space along the fixed disk to a predetermined length of one; a short tool is fixed in the installation space and symmetrically distributed along the diameter direction of the fixed disk, and is located between the long tools, and the distal end of the short tool that rotates with the rotating shaft extends radially out of the fixed disk to a predetermined length of two between the fixed disks.

[0005] Furthermore, the predetermined length one is set to form a mutually cooperating cutting space for performing corresponding cutting operations when the long tool is rotated to the fixed tool position; the predetermined length two is set to form a mutually cooperating cutting space for performing corresponding cutting operations when the segment tool is rotated to the fixed tool position.

[0006] Furthermore, the predetermined length one is greater than the predetermined length two.

[0007] Furthermore, the long tool and the short tool include a plurality of cutting edges for cutting operations.

[0008] Furthermore, dispersion rods are arranged on the side walls of the fixed disk, the dispersion rods are arranged in a ring-shaped manner, and fixed spheres are arranged on the top ends of the dispersion rods.

[0009] Furthermore, the pulverizing operation chamber is a cylindrical pulverizing operation chamber with sieve holes.

[0010] Furthermore, the long tools and short tools between adjacent installation spaces are arranged in a staggered manner. When the corresponding long tools and short tools are rotated to fixed tools, a stepped cutting engagement space is formed between the adjacent long tools and short tools in adjacent installation spaces and the fixed tool.

[0011] Furthermore, the fixed tool units are provided in multiple groups.

[0012] After adopting the above structure, the utility model has the following beneficial effects:

[0013] (1) The long cutter and the short cutter of the rotating cutter unit are respectively installed between the adjacent side walls of the fixed discs through the installation space formed between the adjacent fixed discs, so that the cutters of the rotating cutter unit can be installed separately. In addition, multiple groups of fixed cutters are arranged (multiple groups of fixed cutters are arranged linearly), so that the cutters can be replaced separately when they are worn, thereby reducing maintenance costs.

[0014] (2) By setting the long and short tools, the different lengths of the tools extending out of the edge of the fixed disk form a stepped cutting and crushing space when the tool rotates to the fixed tool body. At the same time, half of the long tools and half of the short tools cooperate with the fixed tool body to cut and crush the cut waste rubber materials, that is, the rubber materials are crushed at different rotation radii, thereby improving the crushing effect.
