Description
Technical field
The present invention relates to field of plastics processing, be specifically related to a kind of device for plastic pelletizing.
Background technology
Plastics are with monomer as raw material, by the macromolecular compound (macromolecules) of addition polymerization or polycondensation polymerized, it is commonly called as plastics (plastics) or resin (resin), can freely change composition and body styles, it is made up of additives such as synthetic resin and filler, plasticizer, stabilizer, lubricant, colorants, can be widely used for the every field such as chemical industry, space flight, military affairs, family, hospital, there is good promotional value and social benefit.
The pelletizing of plastic tube includes fixed-length cut-off and pelletizing cutting, and fixed-length cut-off is important one procedure, and the crudy of this operation directly affects pelletizing effect；Plastic tube is cut in the many employings of existing plastic pipe cutting device outside plastic tube；Its cutting method is generally of two kinds, and one is that plastic tube maintains static, and cutting knife rotates；It two is that cutting knife is motionless, and plastic tube rotates.Owing to the power of fastening plastic tube should not be too big, to prevent from crushing plastic tube, in order to avoid this problem plastic tube generally uses flexible material grip plastic pipe；Therefore using the method that plastic tube rotates cutting plastic tube, the vibrations of usual plastic tube are relatively big, then cutting knife can have certain impulsive force to plastic tube, occur damaging the phenomenon of plastic tube；The most generally use the method cutting plastic tube that cutting knife rotates.Existing plastic pipe cutting device the most only arranges a cutting knife, and therefore cutting knife can form periodically variable pressure at plastic tube outer surface when rotating, and causes plastic tube unbalance stress, also easily causes plastic tube and damages；Additionally can directly fall after plastic tube is cut-off, also often can be damaged by the cutting knife of high speed rotating.
Summary of the invention
It is an object of the invention to provide and a kind of prevent the impaired device for plastic pelletizing of plastic tube.
For reaching above-mentioned purpose, the base case of the present invention is as follows:
Device for plastic pelletizing includes frame；Being fixed with cantilever in described frame, described cantilever one end is fixed in frame, and the cantilever other end is provided with cutting motor；Described cutting motor includes that rotor, stator and cutting mechanism, described stator are fixed on cantilever, and rotor is connected with stator rotation, and has a through rotor of central through hole, stator and cantilever center；Being provided with multiple being provided with along the equally distributed chute of rotor center and cutting knife, and chute in described rotor can be along the slide block of slide；Described cutting knife can slide along rotor radial, and the point of a knife of cutting knife stretches in central through hole, and cutting knife tail end coordinates with slide block wedge surface, and is arranged with return spring outside cutting knife.
This programme is for the principle of the device of plastic pelletizing:
When the device for plastic pelletizing using this programme cuts plastic tube, first central through hole should be put in one end of plastic tube, and plastic tube is fixed；Then start cutting motor, then rotor rotates；When rotor rotates, slide block can be at slide under the effect of inertia force, and owing to cutting knife tail end coordinates with slide block wedge surface, therefore when slide block slides, slide block can extrude cutting knife so that the point of a knife of cutting knife moves towards rotor center, thus top is pressed on plastic tube sidewall.Owing to rotor can drive cutting knife to rotate, and plastic tube is fixed in frame, and therefore cutting knife point of a knife can rotate relative to plastic tube, thus forms otch on plastic tube outer wall；Along with otch is gradually deepened, plastic tube is truncated, and falls within central through hole.
This programme produces and provides the benefit that:
This programme rotor is provided with multiple equally distributed cutting knife, therefore can make plastic tube uniform force when cutting plastic tube, it is to avoid damage plastic tube；The plastic tube additionally cut down can be in central through hole thus can prevent tenesmus, causes plastic tube to damage, and plastic tube can be taken out by one end relative with cutting motor from cantilever；When rotor stops operating, return spring can will push back cutting knife and slide block, and now cutting knife point of a knife will not contact with plastic tube wall, and when therefore can avoid inserting plastic tube in central through hole, cutting knife scratches plastics.
Preferred version one: as the further optimization to base case, being additionally provided with tensioning spring in described chute, tensioning spring two ends offset with slide block and chute wall respectively；Cutting knife is needed to retract, it is necessary to slide block returns to home position；In base case, the return of slide block is by cutting knife jacking sliding block, and owing to slide block and cutting knife wedge surface coordinate, frictional force is relatively big, stuck phenomenon the most often occurs, this preferred version arrange tensioning spring can anti-limited slip block stuck.
Preferred version two: as the further optimization to base case, described rotor is set in outside stator；Being arranged on stator periphery at this programme rotor, be more conducive to install and arrange central through hole, therefore preferred rotor is located at outside stator.
Preferred version three: as the further optimization to base case, fixed magnet on described rotor, stator upper fixed line circle；Owing to rotor needs to rotate, if being arranged on rotor by coil, then needing to arrange brush, therefore this optimization can simplify the structure of cutting motor.
Preferred version four: as the further optimization to base case, described cutting knife is provided with 4 altogether；When cutting knife is less than 4, the stress point of plastic tube is the fewest, and when cutting knife is more than 4, track length will shorten, and therefore ram travel reduces so that the stroke of cutting knife also can reduce, and the most also can increase installation difficulty；Therefore this prioritization scheme both can ensure that plastic tube uniform force, it can also be ensured that the stroke of cutting knife, simplifies structure.
Preferred version five: as the further optimization to base case, described chute is set to arc, can reduce rotor size, and ensure rotor centroid, strengthens the stability that rotor rotates.
