A high-efficiency knife shaft applied to a film crusher and its crusher

Abstract

The invention relates to a high-efficiency knife shaft applied to a film crusher and its crusher, including a main shaft, a knife holder, and a baffle. A front knife rest group and a rear knife rest group are arranged between the front end face baffle plate and the rear end face baffle plate, and many special-shaped knives are installed on the front knife rest group and the rear knife rest group. It slopes from high to low from one end to the other. This case is aimed at the gap between the fixed knife and the moving knife of the domestic film crusher. The blade of the special-shaped knife can theoretically match the cylindrical surface of the fixed knife blade absolutely; considering the processing accuracy of the special-shaped servo grinder, the width of the working section of the spindle is shortened. It can effectively control the physical deviation of the moving knife edge and effectively control the gap between the moving knife edge and the fixed knife edge. This solves the problem of the gap between the above-mentioned moving knife and the fixed knife. The cutting effect is good, the impact is lower instantly during the cutting process, and the vibration is smaller, which can effectively improve the life of the equipment, lower the noise, and reduce the noise pollution of the equipment.

Description

【Technical field】 [0001] The invention relates to a high-efficiency cutter shaft applied to a film crusher and a crusher thereof. 【Background technique】 [0002] At present, the common film crusher in the market is driven by a motor to rotate the moving knife, and its uniform cutting knife is a straight knife. Driven by the inertial force, the film entering the feeding port will have a cutting action with the fixed knife, so that the film will be pulverized and reused. This is the case, for example, in the following three disclosed patents. The patent number is 201120138314X, the name is a rotary cutter for a film crusher, and the announcement date is 2011.11.30. 2011201480385, the name is a rotary cutter for a film crusher, and the announcement date is 2011.11.23. The patent number is 2014202379198, the name is a film crusher, and the announcement date is 2014.09.10. [0003] The moving tool consists of a spindle, a tool holder and multiple sets of blades. The blade is ...

[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
