Hob Slicer

Abstract

The invention discloses a hob type slicing machine, particularly discloses a hob type slicing machine applied to the field of chemical cellulose production, and aims to prolong the service life of a transverse cutter and reduce the equipment running and maintenance costs. The hob type slicing machine comprises a machine body, an upper hob, a lower hob, the transverse cutter, a dead knife, an upper bracket, a lower bracket, a lower hob bearing seat, an upper hob bearing seat, a transverse cutter bearing seat, a dead knife holder, a pre-tightening nut, an upper box transverse cutter box plate and a top unloading device, wherein the top unloading device is arranged between the upper bracket and the lower bracket. By adopting a method of additionally arranging an adjusting gasket on the dead knife, the coping times can be increased to the maximum extent, namely, the cutting accuracies of the transverse cutter and the dead knife are increased through the top unloading device, the coping period can be prolonged, and the coping frequency is lowered. Temperature stability of the cutting edges of the transverse cutter and the dead knife is ensured by adopting a compressed air spray device, and high-accuracy long-term stable running of the transverse cutter and the dead knife can be kept.

Description

technical field [0001] The invention relates to a hob-type slicer, in particular to a hob-type slicer applied in the field of chemical cellulose production. Background technique [0002] The hob slicer is mainly composed of three parts: feeding system, slitting system and cross-cutting system. The flake pulp is pulled by the mechanical guide rail and pushed to the slitting system under the monitoring of the sensor. The incoming material is cut into strips by two rotating linkage knives. They are sent to the cross-cutting system; the lengthwise-cut pulp strands are cut into pellets by the hobs on the cross-cutting knives, and the pellets fall into the receiving hopper below and are drawn away. Due to the high surface hardness and toughness of the pulp, it is not easy to cut, and the humidity in the south is high, and it is easy to absorb moisture. Grinding and sharpening. The period of grinding and sharpening is generally once every 300 tons of pulp is cut, and the diamete...

AI Technical Summary

Problems solved by technology

Therefore, if the number of grinding times of a horizontal knife does not exceed 10, it will be scrapped.

However, the cost of a cross-cutting knife is high, so frequent replacement of the cross-cutting knife will greatly increase the production cost

In summary, there is no hob slicer in the prior art that can prolong the service life of the cross-cutting knife and reduce the cost of equipment operation and maintenance.
