Abstract
The utility model discloses a production device for a BOPP (Biaxially-Oriented Polypropylene) master batch additive. The production device mainly comprises a feeding hopper, a spiral feeder, a double screw extruder, a cooling water groove, a granulator and a vibration sieve, wherein an iron removing device is arranged between the feeding hopper and the spiral feeder, and can be used for clearing metal foreign matters in raw materials to prevent metal foreign matters from entering the double screw extruder and causing mechanical damages; a transmission motor of the spiral feeder is a speed regulating motor, and can be used for adjusting the feeding amount of raw materials conveniently according to different production processes to ensure melting and copolymerization reaction effects of raw materials; eight groups of heating region are formed in the double screw extruder; a thermal resistance conduction heating way is adopted; and a filter screen is arranged at the tail end, so that raw materials or foreign matters which are not molten completely can be prevented from being extruded.
Description
(1) technical field
The utility model relates to field of plastics processing, is specifically related to a kind of production and processing device of BOPP masterbatch additive.
(2) background technology
Along with the continuous development of flexible package industry, ordinary packing has satisfied not the people's life requirement, and the paper class Soft Roll market demand is growing.The BOPP film is wherein a kind of functional plastic packaging material with superperformance; Kind of series of products surplus the antifogging film that development forms, heat-sealing film, ultra-thin high matt film, torsion film, the label film etc. ten have been widely used in the packaging industries such as food, clothes and handicraft.BOPP masterbatch additive is in process, and is generally all composite through flowing freely particle by polyphosphazene polymer alkene alpha-olefin, finally makes mixing polymer, is the top layer additive of producing the BOPP function film.Because the difference of the raw material of types of functionality sexupara feed additives is bigger; And it is all variant to the melting temperature in the process of manufacture, copolyreaction duration etc.; Particularly the production technology of masterbatch additive and masterbatch has bigger difference, and general masterbatch process units can not adapt to the production and the processing of some special masterbatch additives.
(3) summary of the invention
The utility model provides a kind of processing unit (plant) of suitable BOPP film masterbatch Additive Production, and its main technical schemes is following:
A kind of process units that is used for BOPP masterbatch additive; Mainly comprise feeding hopper, scroll feeder, double screw extruder, bosh, pelleter and vibratory sieve; Be provided with a deironing apparatus between said feeding hopper and the scroll feeder; Scroll feeder can feed the raw making materials of masterbatch additive to the head chamber of double screw extruder through feed opening by the stability of flow ground of setting, and raw material is extruded and passed through to draw tie rod from the afterbody of double screw extruder after the melting and copolyreaction of double screw extruder; Make many group strip material get into immersion cooling in the bosh; The strip material gets into the pelleter pelletizing after cooling and drying, be discharged in the vibratory sieve by pelleter subsequently and sieve; The finished particle material that granularity meets directly packs through feed opening, and the powder-material that screens out out then carries out recycling through the discharging opening of vibratory sieve bottom.
As preferably, the thermal treatment zone of the described double screw extruder of the utility model is provided with 8 groups, and adopts thermal resistance conduction mode of heating.
As preferably, the utility model also is provided with a screen pack at the tail end of double screw extruder, can prevent to extrude without the raw material or the foreign matter of melting fully.
As preferably, the driving motor of the described scroll feeder of the utility model adopts buncher, can carry out speed regulation according to the flow size of feeding material.
The beneficial effect of the utility model is embodied in: be provided with a deironing apparatus between feeding hopper and the scroll feeder, can the metallic foreign body in the raw material be removed, prevent to cause mechanical destruction in the metallic foreign body entering double screw extruder; Adopt the feeding manner of adjustable-speed, can regulate the feed quantity of raw material easily, guarantee the melting and the copolyreaction effect of raw material according to the difference of production technology; The screen pack that the double screw extruder tail end is provided with can prevent to extrude without the raw material or the foreign matter of melting fully, guarantees the reliability of melting material traction and tie rod.
