Abstract

The utility model provides a dual roller swinging granulating machine, which comprises a gear case, roller which are provided with granulating blades thereon and pivotedly arranged on the gear case, a motor output shaft which is connected with the roller and used for driving the roller, and a screen cloth which is fixedly arranged outside the rollers on a cloth support pipe. The dual roller swinging granulating machine is characterized in that a main shaft is pivotedly arranged on the gear case, and connected with and driven by the motor output shaft; one end of an eccentric crank is pivotedly arranged on the end surface of the main shaft, and the other end thereof is pivotedly arranged on a lifter rack; a driving shaft and a driven shaft are pivotedly arranged on the gear case, the lifter rack engages with the gear arranged on the driving shaft, and the driving gear arranged on the driving shaft engages with the driven gear arranged on the driven shaft; the roller is arranged on both the tail end of the driving shaft and the tail end of the driven shaft and provided thereon with the granulating blade; and the W-shaped screen cloth is fixedly arranged on the cloth support pipe, the two rollers are respectively positioned inside the two recesses of the W-shaped screen cloth, and the cloth support pipe is fixedly arranged inside the granulating machine cabinet. In the dual roller swinging granulating machine, the two rollers are driven by one motor to drive one main shaft, resulting in a compact structure; and due to the dual-roller design, the material has two treatment spaces, so as to improve the yield compared with the prior art.

Description

The twin-roll oscillating granulator

Affiliated technical field

This utility model relates to a kind of granulation machinery of making medicine or food or chemical granule goods.

Background technology

Granulator is widely used in the industry such as medication chemistry food, and it can make the moist powder mixture granule of all size, so that be pressed into various moulded products after the oven dry.It also can be pulverized condensing into blocky dried shape material, so that make homogeneous granules.

As shown in Figure 1; on having, establishes existing single tumbling granulator the cylinder 2 ' of granulating cutter 20 '; cylinder ' the outer granulation screen cloth 1 ' that is fixedly arranged on the support webmaster 101 ' that is provided with; support webmaster 101 ' is installed in the granulation cabinet; cylinder 2 ' rotation makes the material movement that falls between cylinder 2 ' and the screen cloth 1 ', and is forced to extrude screen cloth 1 ' and the formation granule by granulating cutter 20 '.

The defective of single cylinder granulator is: the cylinder direction of rotation is single, causes screen cloth to be subjected to the power of a state for a long time, and screen cloth two ends discontinuity, causes screen life-span short, fragile.Material can be processed the space limited, production capacity is restricted.

Summary of the invention

This utility model provides a kind of twin-roll to wave granulator, and purpose is to solve the prior art problem, provides a kind of life-span long, compact conformation, the granulator that output is high.

This utility model technical scheme that adopts of dealing with problems is:

Twin-roll waves granulator, comprises gear-box, on establish granulating cutter cylinder be hubbed at gear-box, motor output shaft connects and head roll, cylinder is provided with the screen cloth that is fixedly arranged on the support webmaster outward, it is characterized in that: have the main shaft that is hubbed at gear-box, motor output shaft connects and drive shaft; Have eccentric mechanism, an end off-centre of eccentric mechanism is hubbed at the main shaft end face, and the other end of eccentric mechanism is hubbed at a lifter rack; Has driving shaft and driven axle is hubbed at gear-box, the gears engaged of establishing on lifter rack and the driving shaft, the driven gear of establishing on driving gear of establishing on the driving shaft and driven axle engagement; Driving shaft and driven axle end are equipped with cylinder, are equipped with granulating cutter on the cylinder; Be installed with W type screen cloth on the support webmaster, above-mentioned two cylinders lay respectively in two depressions of W type screen cloth, and the support webmaster is installed in the granulation cabinet.

The beneficial effects of the utility model: have two and be synchronized with the movement but the opposite cylinder of rotation direction, thereby, prolonged the life-span of screen cloth to the uniform application of force about screen cloth formation.Only need main shaft of a driven by motor just to drive two cylinders, compact conformation.The design of two cylinders makes material have two processed spaces, so the production ratio prior art promotes.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 2; twin-roll of the present utility model waves granulator; have main shaft 3 and be fixedly arranged on gear-box 100; the motor output shaft (not shown) drives worm screw 4 with various prior art power trains such as chain type, belt-type, gear train, thereby worm screw 4 drives turbine 30 with turbine 30 engagements that are sheathed on the main shaft 3.In the present embodiment, main shaft is fixedly arranged on gear-box, turbine is hubbed at gear-box, and turbine is driven, and in other embodiments, can be made as that turbine is fixedly arranged on main shaft and main shaft is hubbed at gear-box, and main shaft is driven, and the effect that obtains is identical, belongs to equivalent technologies.

As Fig. 2, shown in Figure 3, an end off-centre of eccentric mechanism 5 is hubbed at turbine 30 end faces, and the other end of eccentric mechanism 5 is hubbed at a lifter rack 6.

As Fig. 2, shown in Figure 4, driving shaft 211 and driven axle 221 are hubbed at gear-box 100,211 gears of establishing, 213 engagements on lifter rack 6 and the driving shaft, driven gear 222 engagements of establishing on driving gear of establishing on the driving shaft 211 212 and the driven axle 221; Driving shaft 211 and driven axle 221 ends are provided with

cylinder

21,22 separately, are provided with granulating cutter 210,220 on the

cylinder

21,22 separately.

As Fig. 5, shown in Figure 6, be installed with W type screen cloth 1 on the support webmaster 101, above-mentioned two

cylinders

21,22 lay respectively in two depressions of W type screen cloth 1, and support webmaster 101 is installed in the granulation cabinet 102.

During operation, turbine rotation, the crank that is pivoted on the turbine drives the reciprocal lifting of lifter rack, and lifter rack drives periodically back and forth rotation of driving shaft, and driven axle is undertaken back and forth rotating with the periodicity of driving shaft switched in opposite by the driving shaft gear starting.Like this, the driving shaft end is drunk the terminal set cylinder of driven axle and is also done the opposite periodicity crankmotion of direction, the wet shape material that set granulating cutter will fall between cylinder and the screen cloth on it is forced to extrude screen cloth and form granule, maybe squeezes dried shape material broken and extrudes screen cloth.
