Embodiment 1

[0058] Such as figure 1 As shown, a circular tooth cutter for a plastic pulverizer includes a cylindrical cutter body 100, cutter teeth 110, tooth grooves 120 and mounting holes 130 are provided on the cutter body 100, and 40 cutter teeth 110 are evenly distributed In the peripheral length direction of the cutter body 100, the cutter tooth 110 is provided with a cutting edge surface 111, combined with figure 2 As shown, the blade angle formed by the cutting edge surface 111 is θ, θ=55°, and the angle α formed between the cutting edge surfaces 111 on two adjacent cutter teeth 110 is 9°; The space formed between two cutter teeth 110 is an arc angle square groove, that is, an arc surface 121 is provided on the edge of the slot bottom length direction of the tooth groove 120, wherein the radius of the arc surface 121 is 1 mm, preventing the teeth from The groove bottom of the groove 120 forms a sharp corner, and the sharp corner is in the process of crushing. When the material c...

Embodiment 2

[0073] A round-toothed cutter for a plastic pulverizer in this embodiment and its grinding tooling and processing technology are basically the same as in Embodiment 1, the difference being that there are 30 cutter teeth 110, that is, two adjacent cutter teeth 110 The angle α formed between the cutting edge surfaces 111 is 12°; the edge angle formed by the cutting edge surfaces 111 is θ, θ=50°; the radius of the arc surface 121 is 1.3 mm.

[0074] According to the above description of the grinding tooling structure of the circular tooth cutter for plastic pulverizers, the following is the method of using the grinding tooling, and the steps are as follows:

[0075] (1) The installation unit 200 is fixed on the mold base 500 through its support 230 , the positioning unit 300 is fixed on the mold base 500 through its fixing base 340 , and is located on one side of the installation part 210 on the installation unit 200 ;

[0076] (2) Fit the installation hole 130 of the tool body 1...

Embodiment 3

[0082] In this embodiment, a circular tooth cutter for a plastic pulverizer and its grinding tooling and processing technology are basically the same as in Embodiment 1, the difference being that there are 50 cutter teeth 110, that is, two adjacent cutter teeth 110 The angle α formed between the cutting edge surfaces 111 is 7.2°; the edge angle formed by the cutting edge surfaces 111 is θ, θ=60°; the radius of the arc surface 121 is 0.7 mm.

[0083] According to the above description of the grinding tooling structure of the circular tooth cutter for plastic pulverizers, the following is the method of using the grinding tooling, and the steps are as follows:

Abstract

The invention discloses a circular tooth knife for a plastic pulverizer and a grinding tool and a processing technology thereof, and belongs to the technical field of mechanical cutters. The circular tooth knife comprises a cylindrical knife body, n knife teeth are uniformly distributed in the length direction of the periphery of the knife body, n is larger than or equal to 30 and smaller than or equal to 50, a tooth groove is formed between every two adjacent knife teeth, and arc faces are arranged at the edges in the length directions of the groove bottoms of the tooth grooves. The grinding tool comprises a mounting unit, a positioning unit and a grinding unit, the mounting unit is used for supporting the knife body to be processed, the positioning unit is used for limiting rotation of the knife body on the mounting unit, and the grinding unit is used for polishing cutting edge faces of the knife teeth; and the mounting unit is located between the positioning unit and the grinding unit. The processing technology of a round blade is that after linear cutting is carried out, the grinding tool is used for grinding and machining the cutting edge faces. By means of the circular tooth knife, the sharpness of the circular tooth knife can be ensured, the service life can be prolonged, and the cutting edge faces of the knife can be conveniently and accurately ground.

Description

technical field [0001] The invention belongs to the technical field of mechanical cutting tools, and more specifically relates to a circular-toothed cutting tool for a plastic pulverizer, a grinding tool and a processing technology thereof. Background technique [0002] The plastic shredder is to process waste plastics, rubber, etc. into granular scraps to achieve the purpose of reducing the size of the materials. Generally, the cutting work of the pulverizer is carried out by the cooperation of the circular-toothed knife and the fixed knife. Among them, the purpose of cutting materials is achieved through the high-speed rotation of the circular-toothed knife and the shearing of the fixed knife. The circular-toothed knife can be adjusted To control the size of the chopped particle size. [0003] The part used to cut the material on the round tooth knife can be called the knife tooth. There are multiple knife teeth for cutting the material on the round tooth knife. Generally...
