Rolling cutter grinder

Abstract

A hob pulverizing machine comprises a stander (6) and a hob mounted on the stander. The hob comprises a horizontal rotating shaft (2) and a moveable knife tackle (1) installed on the rotating shaft. The moveable knife tackle has a subassembly of blades with cutting edge (15). The blades are separated by a range spacer (4). The rotating shaft of the moveable knife tackle is connected with a gear (5). A meshed cylinder (7) is arranged outside the moveable knife tackle. One or more than one comb-shape stationary knives (11) are arranged on the inner wall of the cylinder along the direction of circumference. The comb of the stationary knife and the blades of the moveable knife tackle alternate with each other and match. The top of the cylinder is provided with a feed opening (8). The bottom of the cylinder is provided with a discharge opening (10). The utility model provides the hob pulverizing machines that can pulverize wet and cellulosic materials. The particle size of the wet and cellulosic materials is consistent. The utility model has high efficiency and simple structure. And caulking materials do not stick easily and inlet amount can be adjusted.

Description

technical field [0001] The invention relates to the technical field of material crushing equipment, in particular to the technical field of crushing equipment for crushing high-fiber materials such as tobacco leaves, leaf stems and waste tobacco sheets into uniform and small-grained materials. Background technique [0002] At present, there are mainly three types of equipment for crushing materials: hammer type, grinding type, and extrusion type. The hammer crusher is equipped with a hammer on the rotating shaft, and the hammer is driven by the rotating shaft to hammer the material. When the material is dry and brittle, the material can be hammered into powder or small flakes. When the hammer is wet or When there is fibrous material, it is difficult for the hammer to crush the material, and it will form sticky flakes, causing the outlet to be blocked. The grinding type crusher grinds the material into small particles through the mutual friction between the tooth grooves on ...

Problems solved by technology

[0003] In the tobacco industry, due to the different water content and high fiber content of recycled tobacco leaves, tobacco stems and waste tobacco sheets, the crushed materials cannot achieve the required uniform crushed particles with existing crushing equipment
