Description

Improve pellet device

Technical field

The utility model is related to plastic granulator technical field, more particularly to a kind of to improve pellet device.

Background technology

The operation principle of traditional waste plastics recovery extruding granulator is by single-step form or two steps type extruder, by plastics Melt filteration, extrudes tie rod, then the pelletizing after cooling and solidifying, and underwater cutpellet extruding granulator is without tie rod or can not to draw Under conditions of bar, directly a kind of novel mechanical of pelletizing, melt pelletizing are contacted simultaneously with cooling water in the moment of melt extrusion die face There is obvious advantage with respect to solid-state pelletizing.Because plastics are scraped by blade under melt state, solidified after circulating water , the high polymer of different viscosities can use this granulating form, and pelletizing will not form any dust under melt state, and cut Particle shape shape is regular, and packaging, transport are more convenient；The load and pelletizing speed of die head are adjusted according to extrusion capacity Auto-matching, To change the size of pelletizing, it is also possible to which knife rest when manually using different blade numbers changes pelletizing size and shape；Pelletizing, Cooling combines together and eliminates 4-6mm cold rinse banks long, greatly reduces floor space；Prilling realizes automation, operation Convenient, noise is relatively low, chipping qualities is good.With the yield bigger than traditional tie rod pelletizing, lower energy consumption.

Underwater cutpellet granulation unit generally comprise single-step form or two rank vented extruders, underwater pelletizer, flexible tool rest, Automatic dehydration（Drying）Device, shaker separator, blast system, gather materials hopper, control system composition.When uniform high-temperature fusion Shape material is from upstream equipment（Reactor/screw extruder/Melt Pump etc.）End enters die head runner, and material leaves mould just The pelletizing machine knife blade rotated at a high speed during nib is cut into drop and enters in processing water, because particle specific surface area is maximized Physical characteristic and fusing drop-wise polymer with processing water the temperature difference, drop solidifies and forms the particle close to spheroid. The granulation mode of this " somewhere between fervent and cold cut critical condition " determines that it can be good at competent molten state intensity difference, glues Property big, high to heat sensitivity material granulation operation.

When plastic pelletizing is processed, pelletizing machine knife blade and die head cooperating, pelletizing machine knife blade under motor driving at a high speed Rotation, the material of high-temperature fusion is extruded from die head, and plastic grain is cut into by pelletizing machine knife blade；During this, pelletizing machine knife Piece is in close contact with die surfaces, therefore pelletizing machine knife blade is extremely susceptible to abrasion, and existing resolving ideas are by improving The material property of blade and die head, lifts the anti-wear performance of cutter and die head, but this way still cannot avoid wearing and tearing, And the complex manufacturing technology of blade and die head, high cost.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of improvement pellet device, is not moving integrally pelleter feelings Under condition, the cutter of pelleter and the fine setting of die head position can be realized, thus when compensating blade abrasion with die head working face it Between gap, it is ensured that pelletizing specification meet require.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows：

One kind improves pellet device, including motor, main shaft, sliding axle, cutter group and regulation rotating disk, the master Axle is arranged in a base bearing mounting seat by clutch shaft bearing and second bearing, and described main shaft one end passes through driving wheel group and transmission Belt is connected with the motor；Through hole is provided with the main shaft, the sliding axle forms gap and coordinates with the through hole； The sliding axle is connected with the other end of the main shaft by a slide key；The cutter group is arranged on the end of the sliding axle Portion, the cutter group is fitted close with die head working face, and the other end of the sliding axle passes the main shaft, by the 3rd axle Hold and be arranged on moving shaft holder, the moving shaft holder is arranged on the end of the base bearing mounting seat by being oriented to annulate shaft, The moving shaft holder outside is provided with regulation rotating disk, drives the moving shaft holder to be moved along the guiding annulate shaft.When using, Regulation driven by rotary disc moving shaft holder is moved along main shaft to die head direction, sliding axle is driven relative to main axle moving, by cunning Dynamic key ensures the power connector relation between main shaft and sliding axle, and so as to drive cutter group to move, regulation is cut for sliding axle movement Gap length between cutter group and die head working face, realizes the fine setting between cutter group and die head working face.

Further, it is described guiding annulate shaft be integrally formed with the housing of the base bearing mounting seat, it is described guiding annulate shaft with The main axis parallel is set, and the guiding annulate shaft is coaxially disposed with the main shaft.

Further, the moving shaft holder is set along the guiding annulate shaft movement, and the sliding axle is arranged the described 3rd Bearing, the 3rd bearing is arranged in the moving shaft holder by a fixture.

Further, the cutter group is arranged on cutting interior, and described cutting chamber one end and the die head are sealed and connected Connect, the other end is connected by abutted flange with the base bearing mounting seat.

Further, the abutted flange is provided with second seal with the cutting chamber junction；The abutted flange It is set on the main shaft, the 3rd seal is provided between the main shaft；Set between the main shaft and the sliding axle There is first seal, the cutting chamber forms seal cavity, and the cutter group is arranged in seal cavity.

Further, the upper and lower both sides of the cutting chamber are provided with ventilating water pipe, and cooling water is logical from the downside of the cutting chamber Waterpipe flows to the ventilating water pipe on the upside of the cutting chamber.

Further, the cutter group includes cutting cutter shaft, cutter plate and cutting blade, the cutting cutter shaft with The sliding axle is fixedly connected, and the end of the cutting cutter shaft fixedly mounts the cutter plate, and multiple cutting blades are uniformly pacified Mounted in the cutter plate edge, the cutting blade is arranged in a mutually vertical manner with the die head working face.

Using above-mentioned technical proposal, due to by setting sliding axle in main shaft so that cutter group and die head working face Between gap can be realized under conditions of pelleter is not moved integrally fine setting, move integrally pelleter very trouble, it is necessary to Cut-out cooling water, is easily destroyed the sealing effectiveness of cutting chamber, and the quality of pelleter is larger, it is difficult to ensure the precision of adjustment； Solve this technical problem well by sliding axle, significantly simplify operating process, improve Adjustment precision.
