Cutter shaft of crusher and film crushing processing method

Abstract

The invention relates to a cutter shaft of a crusher. The cutter shaft comprises a main shaft, wherein a front end face baffle plate and a rear end face baffle plate are arranged on the main shaft and are correspondingly arranged at two ends of the main shaft. A first front tool rest, a first rear tool rest, a second front tool rest and a second rear tool rest are sequentially arranged between the front end face baffle plate and the rear end face baffle plate on the main shaft. The first rear knife rest and the second front knife rest are arranged in the middle of the main shaft in an overlapped mode, and the first front knife rest and the second front knife rest are sequentially provided with a special-shaped knife A, a special-shaped knife B, a special-shaped knife A and a special-shaped knife B in the circumferential direction. According to the scheme, through the arrangement method of axial overlapping and tangential dislocation of the knife rest set, namely the arrangement mode of the first front knife rest, the first rear knife rest, the second front knife rest and the second rear knife rest, the special-shaped knife A and the special-shaped knife B which are arranged on the first front knife rest and the second front knife rest are partially crossed and overlapped with the special-shaped knife A and the special-shaped knife B which are arranged on the first rear knife rest and the second rear knife rest, so that axial clearances between cutters in the same group can be avoided, and the cutting efficiency is improved. The cutting effect is good, the instant impact in the cutting process is lower, the vibration is smaller, the service life of equipment can be effectively prolonged, the noise is lower, and the noise pollution of the equipment is reduced.

Description

【Technical field】 [0001] The invention relates to a crusher cutter shaft applied to a film crusher and a film crushing method. 【Background technique】 [0002] At present, the common film crusher in the market is driven by the motor to rotate the moving knife, and the film entering the feed port is driven by the inertial force, and has a cutting effect with the fixed knife, so that the film can be crushed and reused. This is the case for example in the following three published patents. For example, patent No. 201120138314X, named as a rotary cutter for a film crusher, announced on 2011.11.30. 2011201480385, named as a rotary cutter for a film crusher, announced on 2011.11.23. Patent No. 2014202379198, the name is a film shredder, and the announcement date is 2014.09.10. [0003] The moving knife is composed of a main shaft, a knife holder and multiple sets of blades. The blade is straight and inclined, and the blade is straight. The blade is installed at a certain angle w...

[0006] Second, because there will be a gap between the moving knife and the fixed knife, the oblique installation of the straight knife will cause the material to jam or the efficiency will be reduced due to the enlarged gap, because the material will follow the scissors-like shearing action of the blade during the crushing process. , the material will slip axially, and eventually accumulate in the gap between the end face of the moving knife and the end face of the fixed flange of the frame, causing material jams. Another treatment method is to enlarge the gap between the moving knife and the end baffle, resulting in low efficiency
