Autorotation pneumatic slicing knife

Abstract

The invention provides an autorotation pneumatic slicing knife which comprises a knife body composed of an installation back plate and a control body and a knife bit assembly. A driving unit is arranged on the back face of a knife cover of the knife bit assembly and is in driving connection with blades on the front face of the knife cover so as to drive the blades to achieve autorotation motion. In this way, the slicing knife can drive the blades to rotate in the using process, the problem that an upper blade of a traditional slicing knife is driven by a lower blade through friction force, the speed cannot be accurately controlled, and therefore the low-tension coiled material slicing effect is poor is solved, the problem that the blades are prone to being rubbed and becoming blunt is solved, the service life of the blades is longer, the replacement frequency is reduced, the maintaining cost is saved, and the slicing performance is more stable; in addition, the slicing knife further has the upper blade vertical direction fine adjustment function, the horizontal direction movement fine adjustment function and the like, fine adjustment of the cut depth and the left-right gap between the upper blade and the lower blade of the slicing cutter can be achieved according to the slicing requirement, use is flexible, and operation is simple, convenient and rapid; and in addition, the autorotation pneumatic slicing knife is ingenious, reasonable and scientific in structure and easy to produce and machine.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of material cutting equipment, and in particular relates to a self-rotating pneumatic cutting knife. [0003] 【Background technique】 [0004] At present, pneumatic or electronic slitting knives are a kind of processing equipment commonly used in cutting thin and long sheet materials in the coil processing industry. The upper blades of the slitting knives sold on the market are all without driving power. The knife exerts a certain lateral force against the knife and is driven by the active rotating lower knife through friction. The upper and lower blades are prone to bluntness and damage. The speed of the upper knife cannot be precisely controlled, and the cutting performance is poor, so it is not suitable for low Tension-sensitive materials are used, and the service life is extremely short, requiring frequent replacement, which greatly increases maintenance costs. In addition, the blades of these ex...

Problems solved by technology

[0004] At present, pneumatic or electronic slitting knives are a kind of processing equipment commonly used in cutting thin and long sheet materials in the coil processing industry. The upper blades of the slitting knives sold on the market are all without driving power. The knife exerts a certain lateral force against the knife and is driven by the active rotating lower knife through friction. The upper and lower blades are prone to bluntness and damage. The speed of the upper knife cannot be precisely controlled, and the cutting performance is poor, so it is not suitable for low Tension-sensitive materials are used, and the service life is extremely short, requiring frequent replacement, which greatly increases maintenance costs

In addition, the blades of these existing cutting knives cannot adjust the gap between the upper knife and the lower knife according to the cutting requirements, and the operation is extremely inflexible and inconvenient
