Pulverizing cutting head and pulverizer

Abstract

The invention relates to the field of cutting tools, in particular to a pulverizing cutting head and a pulverizer. The pulverizing cutting head comprises a rotating shaft, a fixing disc, cutting bladeshafts and cutting blades; the cutting blade shafts are fixedly connected into two oppositely-formed fixing holes correspondingly and parallel to the rotating shaft; each cutting blade shaft is provided with the M pulverizing cutting blades, and M is positive integral; the rotating shaft drives the fixing disc to rotate, and the fixing disc drives the cutting blade shafts to move; the pulverizercomprises a shell and further comprises a cutting head and a sieve net arranged in the shell body; the sieve net is annularly arranged on the outer side of the pulverizing cutting head, the shell bodyis divided into a pulverizing cavity and a discharging cavity through the sieve net, and the pulverizing cutting head is arranged in the pulverizing cavity; and the shell body is provided with a feeding opening and a discharging opening, the feeding opening is formed in the upper portion of the shell body, the discharging opening is formed in the lower portion of the shell body, the feeding opening is connected with one end of a feeding channel, the sieve net is closely connected with the feeding channel, and the rotating shaft is connected with a motor. According to the pulverizing cutting head and the pulverizer, material temperature rising during pulverizing can be reduced, the pulverizing efficiency is improved, and the congestion problem of the pulverizer is solved.

Description

technical field [0001] The invention relates to the field of cutters, in particular to a crushing cutter head and a crushing machine. Background technique [0002] During the preparation of heat-sensitive materials such as gelatin, these materials need to be crushed to a specified mesh to meet customer requirements. In the process of crushing heat-sensitive materials such as gelatin, it is necessary to use a crushing cutter head, but the existing crushing cutter head is hammer-type, the thickness of the blade is generally greater than 2mm, and the blade is an edgeless blade. The action mode of the pulverized material is hammering and crushing. However, this method is extremely inefficient, generates a large amount of heat, and produces more powdery particles. In addition, due to the high heat, the hot-melt material melts to produce a highly viscous mixture that blocks the mesh, sticks to the shaft and the cutter head, and the use of such a grinder for crushing the cutter he...

Problems solved by technology

In the process of crushing heat-sensitive materials such as gelatin, it is necessary to use a crushing cutter head, but the existing crushing cutter head is hammer-type, the thickness of the blade is generally greater than 2mm, and the blade is an edgeless blade. The action mode of the crushed material is hammering and crushing, however, this method is extremely inefficient, generates a large amount of heat, and produces more powdery particles

In addition, due to the high heat, the hot-melt material melts to produce a highly viscous mixture that blocks the mesh, sticks to the shaft and the cutter head, and the use of this kind of grinder for crushing the cutter head can easily cause congestion of the grinder, resulting in damage to the grinder
