Abstract
The utility model relates to a pulverizing device for recovering waste plastics. A cutting knife disc and a cushion disc which are arranged on two parallel rotary shafts rotate reversely to make cutting work. The cutting knife is provided with multiple blades. The utility model has the advantages of quick cutting, uniform load, no big vibration, high production efficiency and lower energy consumption. The plastic particles which are crushed have comparatively uniform sizes, and the utility model is suitable for crushing soft plastics and waste materials.
Description
The utility model relates to a kind of waste plastics recovery reducing mechanism.
Existing plastic crusher by be fixed on the frame two fixed blades be fixed on two on the rotating cutter-head to three straight shape blades and form cutting mechanism, rely between them relative motion to realize cutting plastics and become particle (piece).Because broken time accounting example is little in a rotation period, bump and extruding phenomenon are arranged in the work, thereby vibrations are bigger, stock-removing efficiency is not high yet, and is poorer to the flexible plastic crushing effect especially.
The purpose of this utility model provides a kind of improved plastic crusher, to improve the efficient that flexible plastic is pulverized, the vibrations of fuselage when reducing work.
Task of the present utility model is finished as follows: rotary-cutting type flexible plastic pulverizer is made up of motor, transmission mechanism, rotating shaft, cutting knife dish, disc, feed hopper and blow tank.Two parallel rotating shafts are arranged, the cutting knife dish and the disc of a plurality of band cutting teeths alternately repeatedly is housed on every rotating shaft respectively, cutting knife dish on rotating shaft and the disc on another root rotating shaft are in equipped, two mutual rotating speed differences of rotating shaft.Five or more a plurality of cutting teeths are arranged on the even distributing position of cutting knife dish periphery, and each cutting teeth all has three or more cutting edge.One or more cutting knife dishes and disc are housed on the every rotating shaft.
This flexible plastic pulverizer is owing to use the disc of rotation to substitute fixed blade commonly used, the cutting teeth that multi-tool edge is arranged more than five is arranged on the cutting knife dish, the ratio that the broken time accounts in a swing circle is big, load is even, shredded plastic is with milling and cut mode, have shredded plastic efficient height, vibrations are little, the granularity after the plastics fragmentation is more even, and the existing same category of device of energy consumption decreases.
Fig. 1 is the utility model A-A profilograph.
Fig. 2 is the utility model B-B drawing in side sectional elevation.
Fig. 3 is the utility model cutting knife dish schematic diagram.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Two parallel rotary axes (7), (8) are housed on support (2), cutting knife dish (3) and four discs (10) of four band cutting teeths (9) alternately are housed on every rotating shaft respectively, and the disc (10) on a rotating shaft upper cutter dish (3) and another root rotating shaft is in assembling.Evenly on the distributing position 25 cutting teeths (9) are arranged at each cutting knife dish (3) periphery, each cutting teeth has three cutting edges, and a main cutting edge (14) and two front cutting edges (15) are wherein arranged.Disc (10) periphery is a shiny surface.The rotating speed difference of two rotating shafts, and direction of rotation is opposite.Motor (12) connects through the same belt pulley of belt (11) (4), and gearratio is 2.5～3.5.Belt pulley driven rotary axle (7) rotates, and by gear (5) travelling gear (6), thereby driven rotary axle (8) rotates, and gear ratio is 1.1～1.5.Cutting is pulverized when giving up flexible plastic, and the flexible plastic that will give up is sent into from hopper (1), relatively rotates through cutting knife dish (3) and disc (10) flexible plastic is carried out milling and shearing, and the plastic grain after cutting is pulverized flows out from blow tank (13).
Claims (4)
1, rotary flexible plastic pulverizer, by motor, transmission mechanism, rotating shaft, the cutting knife dish, feed hopper, blow tank is formed, it is characterized in that having two parallel rotating shafts (7), (8), the cutting knife dish (3) of band cutting teeth (9) is housed repeatedly alternately respectively on every rotating shaft, the cutting knife dish (3) on rotating shaft is in equipped with disc (10) on another rotating shaft, two rotating shafts (7), (8) are the rotating speed difference each other.
2, pulverizer according to claim 1 is characterized in that on the even distributing position of cutting knife dish (3) periphery five or more a plurality of cutting teeths (9) being arranged.
3, pulverizer according to claim 2 is characterized in that each cutting teeth (9) has three or more cutting edge (14), (15).
4, pulverizer according to claim 1 is characterized in that being equipped with one or more cutting knife dishes (3) and disc (10) on every rotating shaft (7), (8).
