A vertical hob cutter

Abstract

The invention provides a vertical type hob tobacco cutter. The vertical type hob tobacco cutter comprises a knife roll and two feeding bins. The knife roll is vertically arranged. The feeding bins are arranged along the circumferential direction of the knife roll. Outlets of the feeding bins are opposite to the knife roll. A tobacco-cutting blade is arranged on the knife roll. The knife roll drives the tobacco-cutting blade to simultaneously cut material in each feeding bin. The vertical type hob tobacco cutter has following beneficial effects: as for the knife roll, horizontal installation is replaced by vertical installation; the two feeding bins are symmetrically arranged on two sides of the knife roll; material can feed in each feeding bin and can also simultaneously feed in the feeding bins, thereby increasing an adjustment range for production capability and improving flexibility of match-production; in the meantime, under the premise that production capability is accommodated and tobacco-cutting quality is ensured, the knife roll can decelerate in order to ensure that the knife roll can operate at the fine rotation speed; and positive and obvious effects on tobacco-cutting quality guarantee and on effective decrease in noises can be exerted.

Description

technical field [0001] The invention relates to tobacco processing equipment, in particular to a vertical hob cutter. Background technique [0002] In a nutshell, cigarette production is mainly divided into two major processes: one is the preparation of shredded tobacco, and the other is crimping and packaging. The former includes preparing (tobacco) leaf and tobacco stem two raw materials according to a certain process, and preparing shredded tobacco that meets the requirements of cigarettes through processes such as heating, humidification, feeding, shredding, drying, and mixing and flavoring. It is called silk making for short, and the production line that completes the whole process of silk making is called silk making line. The shredding machine and the stem cutting machine are the main equipment on the silk production line. The shredding machine and the stem cutting machine have the same structure, but the thickness of the shreds is different, and the parameter settin...

AI Technical Summary

Problems solved by technology

Therefore, the existing arrangement of cutter rollers for shredding is limited by the structure of the shredding machine itself. In order to be able to adapt to a large range of production capacity changes, the usual practice is that the selection of shredding machine capacity is generally too large.

When the flow rate of the incoming material does not change (smaller) much, appropriately reducing the speed of the knife roller can meet the shredding requirements, but the speed is too low will have a certain impact on the quality of the shredded; When it is less than 1 / 2, it is often necessary to change the number of cutting blades distributed on the cutter roller from 12 to 6 at intervals, and then increase the rotation speed of the cutter roller. The removal of the shredded blade is more complicated and time-consuming, which increases the workload of the staff and affects the efficiency of the shredded blade

Therefore, the structural characteristics of the existing shredder limit the effective use range of the production capacity of the shredder, and cannot well adapt to different flow parameter settings on the production line.
