Abstract
The invention discloses a plastic granulating device. The plastic granulating device is characterized by comprising an extrusion disc and a cutting knife; the extrusion disc is arranged at the discharge hole end of a plastic extruder, the extrusion disc is provided with holes of which the diameters are as same as those of required plastic granules, and the cutting knife is attached to the surface of the extrusion disc and rotates on the surface of the extrusion disc; and a cooling device is arranged on the extrusion disc. Preferably, the revolving speed of the cutting knife is adjustable. Through the device, plastic extruded by the screw extruder can be quickly cooled, cut and granulated, and the lengths of the granules are adjustable; and the device is simple in structure, convenient to maintain and replace and low in machining cost.
Description
Technical field
The present invention relates to a kind of plastics machinery annex, particularly relate to a kind of plastic granulating device for the plastic extruder extrusion plastic.
Background technology
The plastics that need plastic extruder is extruded in the plastic processing process carry out granulation, generally adopt the methods such as hobboing cutter pelletizing, because hobboing cutter pelletizing caloric value is larger, so this method is applicable to thermoplastic, not too is applicable to the granulation of thermosetting plastics.
Summary of the invention
The object of the invention is to provide a kind of plastic granulating device that is applicable to the thermosetting plastics granulation for the defective of prior art.
The present invention adopts following technical scheme for achieving the above object:
A kind of plastic granulating device is characterized in that: extrusion dish and cutter; Described extrusion dish is arranged on the discharge port end of plastic extruder, is provided with the hole identical with required plastic pellet particle diameter on it, and described cutter are fitted in described extrusion dish surface, rotate on the extrusion dish surface.
It is further characterized in that: be provided with cooling device on the described extrusion dish.
Preferably: described cutter rotating speed is adjustable.
Cut granulation after the plastic cool that the present invention can make screw machine extrude fast, particle length is adjustable, and is simple in structure, safeguards and change conveniently that processing cost is low.
Description of drawings
Fig. 1 is schematic diagram of the present invention.
The specific embodiment
A kind of plastic granulating device as shown in Figure 1, extrusion dish 1 and cutter 2; Described extrusion dish 1 is arranged on the discharge port end of plastic extruder, is provided with the hole identical with required plastic pellet particle diameter on it, and described cutter 2 are fitted in described extrusion dish 1 surface, rotate on extrusion dish 1 surface.During work, cutter 2 rotate, and will cut into plastic grain from the plastic strip that extrusion dish 1 is extruded.
Be provided with cooling device on the described extrusion dish 1.The plastic strip of extruding in the screw machine cools off fast through the cooling device on the extrusion dish 1, makes the plastic strip sclerosis, is convenient to cut into particle, and the particle after the cutting can not be bonded together.Be applicable to thermosetting plastics by it.
Preferably: described cutter 2 rotating speeds are adjustable.The length that can regulate easily the plastic grain of cutting by the rotating speed of regulating cutter.
Claims (3)
