The guide passage connects with scraping material space.By way of screw feeding can by adjust revolution speed of screw control discharging speed and
Temperature, the pressure of bottom section material, and by Stress control in reduced levels so as to ensure pelletize instant capacity and expanded level, from
And ensure the quality that pharmacy is granulated.
Preferably, multigroup groove is uniformly laid with centered on the axle center of haul flight on the discharging chassis, it is described
Discharge opening is arranged on the bottom of groove, and the thickness of the bottom portion of groove is not more than 2 millimeters, the projection between the groove and groove
It is interconnected to constitute reinforcement.No more than 2 millimeters very thin bottom portion of groove ensure that material still can be scraped in aperture very little,
Reinforcement prevents that thin plate is deformed when scraper beam scrapes material repeatedly.
Preferably, the discharging chassis and guide shell are detachable installation.So as to convenient, the disassembly, cleaning on the chassis that discharges,
Change.
Preferably, the discharging chassis and guide shell, can due to the form fixed using Quick hoop by clamp connection
To make the requirement that each model particle diameter is flexibly met in the discharging chassis of different pore size size.
The bottom surface of haul flight in said structure is scraped material space and is divided into multiple guide faces, and the guide face is being transported
Material flight direction of rotation is provided with an inclination angle, due to the step composition scraper beam that inclination angle is formed between adjacent guide face.
Scraper beam is responsible for scraping material from the pore on discharging chassis.
Preferably, the scraper beam is formed cross in the bottom surface of haul flight.
Further, the top of the feed tube is rack-mount, and motor is also equipped with the support and passes through electricity
Machine drives the axle of rotation, and the axle is rack-mount by bearing block, and the axle is connected by fastening screw and haul flight
Connect.
Further, the feed tube is fixed on support by clip.
Due to the horizontal discharging of conventional helical extrusion die is converted into vertical discharging, kept away using said structure, the present apparatus
The problem of having exempted to interfere after tough material discharges, and by adjusting haul flight rotating speed and bottom scraper beam with going out
The mode of material chassis distance accurately controls bottom squeeze effect, realizes that traditional moulds are difficult to the fine grain discharging completed.
