Abstract

The utility model discloses a rotating cutter type bark mill which is used in timber manufacturing industry, and comprises a rack; two ends of the rack are respectively provided with a feeding port and a discharging port; an upper driving roller and a lower driving roller are arranged at the feeding port; an upper driving roller and a lower driving roller are also arranged at the discharging port; a rotating assembly is positioned between the feeding port and the discharging port; a barking driving motor is arranged on the rack, and is connected with the rotating assembly by a triangular belt; a driving roller torsional spring is connected between the driving roller and the rack; and a transport driving motor is arrange at the lower part of the rack, and is connected with the driving roller by a chain wheel chain transmission assembly. The rotating cutter type bark mill can finish working procedures such as automatic feeding, barking, cutting-up of bark, automatic discharging and the like at one time. Compared with existing the bark mill, the rotating cutter type bark mill improves the efficiency by three times, can peel the bark cleanly and can not damage the timber. The bark peeled is smashed, so that the secondary process is eliminated, and the smashed bark can be used as premium fuel.

Description

Rotor formula bark mill

Technical field

The utility model relates to the bark machinery that a kind of wood-processing industry is used.

Background technology

Existing bark mill comprises frame and rotor assembly two parts mechanism, and frame is connected with the rotor assembly, and the rotor assembly is by motor driven.It is low to exist production efficiency during this machine operation, shells totally, is prone to hinder problems such as timber.

Summary of the invention

Low in order to overcome existing bark mill production efficiency, shell clean, as to be prone to hinder timber defective, the utility model provides a kind of rotor formula bark mill, and this rotor formula bark mill production efficiency is high, and peeling is clean, does not hinder timber.

The technical scheme of the utility model is: this rotor formula bark mill comprises frame; The two ends of frame are respectively equipped with charging aperture and discharging opening, and charging aperture is provided with upper and lower two driven rollers, and discharging opening also is provided with upper and lower two driven rollers; The rotor assembly is between charging aperture and discharging opening; The peeling drive motors is installed above the frame, and the peeling drive motors links to each other with the rotor assembly through V belt, is connected with the driven roller torsion spring between driven roller and the frame; Frame lower is equipped with the feed drive motor, and the feed drive motor links to each other with driven roller through sprocket wheel chain drive assembly.

Described rotor assembly comprises the rotor holder, and bark knife is positioned at the rotor holder, and the front end of bark knife is positioned in the middle of the rotor holder, and the edge of a knife of bark knife front end is provided with the angle of inclination, and angle is 3 °.

Described driven roller comprises roll shaft and spiral plate, and two row's spiral plates are arranged fixing around roll shaft, and two row's spiral plate tail tails join, and afterbody all is positioned in the middle of the roll shaft.The edge of a knife radius of spiral plate is 140～150mm, and angle is 10～20 °.

Bark knife when work, not only flexible, but also appropriate peeling dynamics is arranged, when the cutting edge rotation of bark knife inclination certain angle, peel bark and shred off automatically, accomplish the peeling operation, improve peeling efficient.

The peeling drive motors drives the rotation of rotor assembly through V belt, and in the rotation process of bark knife, cutter hub is under the effect of tension spring; Bark knife and log front end form angle, and log is under the promotion of feeding driven roller, and bark knife peels bark and shred; When the timber of having shelled skin touches the output driven roller; Through the positive and negative rotation of output driven roller, will shell timber and see off, operation process such as promptly accomplish conveying, peeling, bark chopping and see off.

When upper and lower two driven rollers of charging aperture rotate, can timber be sent in the machine; When upper and lower two driven rollers of discharging opening relatively rotate, see the timber after the peeling off.In the course of the work, upper and lower driven roller is under the effect of torque spring and gear, but arcuate movement; Can be adapted to the timber of different-diameter; Spiral plate on the driven roller and timber contact portion have certain inclination angle, help timber like this and send into smoothly and export, thereby improved peeling efficient.

The advantage of the utility model: before trees processing, carry out the mechanization peeling, can once accomplish flow charts such as automatic feed, peeling, bark chopping, self-emptying.Raise the efficiency 3 times than existing bark mill, bark shells only, do not hinder timber.The bark that peels becomes comminution, need not secondary operations, can directly use as high-grade fuel.
