Abstract

The invention discloses an efficient rotating cutter device for waste paper pulping cutting and relates to rotating cutter. The efficient rotating cutter device comprises a cutter body (1) and cutter heads (3), each cutter head (3) comprises a cutter point portion (2), a cutter back (5) and a blade portion (7), the cutter body (1) is in arc-shaped rotary structural fit with the cutter heads (3), and each cutter head (3) is in the shape of an incurved arc. The cutter body and cuter heads are specially designed, a straight cutter is changed into an arc-shaped cutter which is matched with a rotating shaft to form a sickle-shaped working structure, and dual functions of chopping and cutting are achieved by the aid of the rotating cutter. The shortcomings of low cutting efficiency and proneness to breakage and damage of a straight cutter structure of the prior art are overcome, service lives of the cutter heads are prolonged effectively, and a maintenance-free period of waste paper grinding equipment is prolonged. Besides, the efficient rotating cutter device is reasonable in structure, high in cutting efficiency, firm and durable, use cost is reduced, and economic benefits are increased.

Description

A kind of waste paper pulping is cut and is used efficient rotary knife system
Technical field
The invention belongs to paper making equipment technical field, be specifically related to a kind of rational in infrastructure, stock-removing efficiency is high, working stability reliable waste paper pulping cutting efficient rotary knife system.
Background technology
One of four inventions of China of papermaking technology system, along with the progress of technology, papermaking becomes automatic production line by the production of handicraft workshop formula and produces, and substantially increases production efficiency.Prior art slurrying mainly contains two kinds, and one is former material slurrying, and one is waste paper pulp-making.The natural resourcess such as the former at substantial timber; The latter not only can reclaim waste and old paper as paper making raw material, is more to save natural resources.The advantage of the latter is simple process, the industrial waste of generation, and especially wastewater flow rate is few and relatively clean, and it is comparatively easy to deal with, also little to the pollution of environment.Prior art waste paper pulping can be taked, and direct pulping process is stirred in direct water logging, can clean like this to waste and old paper, and silt particle can directly sink at the bottom of pond, without the need in later process row desanding again.Although clean plasm prepared by this technique can directly use without the need to post processing, water wasting, effect is low, cannot meet the large needs produced of industry.Therefore, many employings directly add water pulverizing, then go follow-up desanding, impurity elimination technique.Waste paper is pulverized and is mostly to take peeling knife, and the reasons in structure of the peeling knife of prior art, not only stock-removing efficiency is low, and fragile, causes O&M cost to raise.For this reason, develop a kind of structure simple, stock-removing efficiency is high, and robust waste paper pulping cutting efficient rotary knife system seems very meaningful.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, stock-removing efficiency is high, robust waste paper pulping cutting efficient rotary knife system.
The object of the present invention is achieved like this, relates to peeling knife, comprises cutter hub and cutter head, and described cutter head comprises nose part, the knife back, blade part, it is characterized in that: described cutter hub coordinates with the curved rotary structure of cutter head, and described cutter head is interior curved arc.
The present invention adopts special cutter hub and segment design, and straightening cutter is curved knife, coordinates form sickle work structuring with rotating shaft, forms cutter cut and the double action of cutting by means of revolving force.Instant invention overcomes prior art straight knife structure stock-removing efficiency low, and easily brokenly lose bad drawback, effectively extend the service life of cutter head, extend the non-maintaining phase of waste paper disintegrating apparatus.The present invention is rational in infrastructure, and stock-removing efficiency is high, sturdy and durable, reduces use cost, improves economic benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated, but limited the present invention never in any form, and any conversion done based on training centre of the present invention or replacement, all belong to protection scope of the present invention.
As shown in drawings, the present invention relates to peeling knife, comprise cutter hub 1 and cutter head 3, described cutter head 3 comprises nose part 2, the knife back 5, blade part 7, it is characterized in that: described cutter hub 1 coordinates with the curved rotary structure of cutter head 3, and described cutter head 3 is in interior curved arc.
Be bent to form cutter hook portion 4 between described cutter hub 1 and cutter head 3, arc radius is 35 ~ 45mm.
Be bent to form cutter root 6 between described cutter hub 1 and the knife back 5, arc radius is 95 ~ 105mm.
Described blade part 7 is in circular arc, and its radius is 560 ~ 635mm.
Described knife back portion 5 is in circular arc, and its radius is 850 ~ 1150mm.
Described nose part 2 arrange to edge tilted edge bevel 8.
Between described cutter hub 1 and cutter head, retainer ring is set, uniform fixing hole on described retainer ring.
Fig. 2 shows knife back structure, arrange between the described knife back 5 and point of a knife end 9 with point of a knife end 9 width quite and the point of a knife section tilted to point of a knife.
Fig. 3 shows point of a knife end construction, and described point of a knife end 9 width is 110 ~ 130mm.
Fig. 4 shows blade part, and the width of described blade part 7 extends to cutter hook portion, and arranges inclined plane from cutter hook portion to nose part.
operation principle of the present invention and the course of work:
The present invention adopts special cutter hub and segment design, and straightening cutter is curved knife, coordinates form sickle work structuring with rotating shaft, forms cutter cut and the double action of cutting by means of revolving force.During use, the present invention and propeller are coaxially assembled, and affixed by fixing hole bolt.The present invention is rational in infrastructure, and stock-removing efficiency is high, sturdy and durable, reduces use cost, improves economic benefit.Instant invention overcomes prior art straight knife structure stock-removing efficiency low, and easily brokenly lose bad drawback, effectively extend the service life of cutter head, extend the non-maintaining phase of waste paper disintegrating apparatus.
