Description

Plastic crusher

The utility model relates to a kind of plastic crusher technical field.

Development along with plastics industry, plastic reclaimed utilization is attracted attention by common people, in the plastic reclaimed process, generally plastics to be pulverized, especially in the enterprise of plastic product, have a large amount of plastics substandard products need pulverize reprocessing, pulverizing will be adopted pulverizer, conventional in the past plastic crusher has adopted rotary-cutting type mechanism, is reported that by 96215268.4 Chinese patent the pulverizer, its profile is tall and big as the patent No., machine is heavy, and it is very inconvenient to use.Weldering three block plate fin start tool rests on the cutter shaft install three moving knife, and dynamic and static balance can't reach requirement, produce greatly vibration and noise when rotating at a high speed, and machine must be fixed with foundation bolt.Be level when forming cutting pair between moving knife and the stationary knife and hit the pulverizing state, consumed power is big, blade abrasion is fast, tool setting seat-box body requirement of strength height, because the big charging aperture of vibration, base and tool rest case must be with being connected and fixed than king-bolt, thus the old type of tradition exist energy consumption height, noise greatly, defective such as inconvenient operation.

The purpose of this utility model is to provide the plastic crusher that a kind of static and dynamic equilibrium performance is good, cutting effect is good, energy-conservation.

The technical solution of the utility model is to realize like this.This plastic crusher, include feed hopper, the tool rest case, support, motor, driving-belt, belt pulley, flywheel, knife rest, feed hopper is arranged on the tool rest case, in the tool rest case knife rest is arranged, support is below the tool rest case, knife rest is by main shaft on its moving knife cutterhead, belt pulley is connected with motor reel with driving-belt, it is characterized in that described knife rest moving knife cutter head structure is that a plurality of moving knife cutter disc groups detachably are fixed on the main shaft altogether, and each cutterhead certain angle that staggers mutually, be to be fixed with moving knife on the cutterhead of basic shape with regular polygon, moving knife with radially form an angle.

Plastic crusher design equilateral triangle of the present utility model is the cutterhead of basic shape, half position is adorned moving knife and the adjustment screw adjusting play is arranged on each bar limit, half position is an orthodrome spill capaciting material groove, a plurality of cutter disc groups are synthesized stepped assembled cutter head, many moving knife is evenly distributed in the tool rest case, moving knife and stationary knife composition cutting pair angle has played great changes like this, near reaching vertical, thoroughly change grinding mode, the change level is hit and is pulverized to pulverizing near vertical shear, reach and reduce the cutting energy consumption to greatest extent, the orthodrome capaciting material groove is set on the cutterhead contains chip index as far as possible after reducing pulverizing, the multitool assembled cutter head can significantly improve the cutting probability, raise the efficiency, output.Cutter shaft, cutterhead, intermediate plate, belt pulley, flywheel etc. rotate rotating part, do not allow to stay black skin, and dynamic and static equilibrium ratio is more satisfactory.Suitable balance when machine runs up, noise is extremely low.Moving knife, stationary knife are made of alloy tool steel, repeatedly reconditioning, and the life-span is long, and blade is adjusted easy accessibility.Unique screen designs adopts the stairstepping sieve screen apertures, both can increase web plate thickness to gain in strength and the life-span, can improve discharging speed again, improves output.In a word, energy-efficient, convenient, flexible, super low noise characteristics that this plastic crusher has suit to apply on the plastic processing industry.

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail.

As shown in the figure, this plastic crusher includes feed hopper 1, tool rest case 2, support 6, motor 4, driving-belt 3, belt pulley, flywheel, knife rest, whole pulverizer is canard configuration, feed hopper 1 is arranged on the tool rest case 2, in the tool rest case knife rest is arranged, support 6 is below the tool rest case, the tool rest case is a up/down perforation, enter unit of plastic from feed hopper like this, in the tool rest case, cutting is pulverized between knife rest moving knife and stationary knife, sieve through screen cloth again, fall in the support in the bucket, knife rest is by main shaft 7 on its moving knife cutterhead, belt pulley, driving-belt 3 is connected with motor reel, knife rest moving knife cutter head structure is that four moving knife cutterheads 11 are shaped on axis hole, be enclosed within on the main shaft 7, and by three key or double key system on main shaft, both sides press from both sides upper clip 9 simultaneously, both sides intermediate plate and four moving knife cutterheads are divided into two groups, with one of them cutterhead is common contiguous block, have two screws, be fixed up with bolt 8, can certainly intermediate plate and each moving knife cutterhead have a through hole, be fixed up with screw bolt and nut, in order to improve cutting effect, four cutterheads certain angle that on main shaft, staggers mutually preferably, moving knife 12 is distributed on circumference as far as possible evenly, and the cutterhead matrix is an equilateral triangle, by adorning the moving knife one side and radially forming an angle, making like this moves between moving knife and the stationary knife moves near vertical shear, improve cutting effect, improve output, reduce the cutting energy consumption, the cutterhead another side is that orthodrome capaciting material groove 114 is with the chip index that contains after minimizing is pulverized as far as possible.Also be provided with the moving knife adjustment structure on the cutterhead, be shaped on the face of installation moving knife screw 113 is installed, the back is provided with projection 111, be shaped in the projection and regulate screw 112, can debug the joint screw, moving knife is provided with regulating tank simultaneously, with screw 10 and pad moving knife is assemblied on the moving knife cutterhead installed surface, and can regulate moving knife and stationary knife gap, make the cutting crushed work in ideal zone.Also be provided with curved screen 13 below the knife rest, be distributed with the up-small and down-big stairstepping sieve screen apertures 14 in aperture on the screen cloth, quicken blanking.Motor 4 is to be directly installed on the support 6, the support bottom is provided with movable castor 5, to make things convenient for the machine mobile working, electric control box also is contained on the support, and is provided with safety interlock, establishes slanting baffle before the described tool rest case first half, after establish the circular arc baffle plate, casing intensity height does not stay the dead angle again, does not have the cumulative material.
