Description

Barrier properties for gases degradable plastic masterbatch, conical double screw extruder, injection molding production add Work assembly line

Technical field

The present invention relates to injection molding machine technical fields, are especially a kind of barrier properties for gases degradable plastic masterbatch, prepare gas The conical double screw extruder of body barrier property degradable plastic masterbatch utilizes barrier properties for gases degradable plastic masterbatch injecting products Injection molding produce and process assembly line.

Background technique

Plastics play huge effect in national economy, bring great convenience to people's life, however plastics Raw materials for production still mainly come from fossil resources, be not easy to realize natural degradation in addition and also lead to it the features such as recycling Become another environment killer.From angle of sustainable development, studying degradation plastic has been that situation is compeled.Degradation plastic Refer to and a certain amount of additive (such as starch, modified starch or other celluloses, photosensitizer, biology drop are added in process of production Solve agent etc.), decline its stability, after be easier to the plastics degraded in the natural environment.PHA degradative plastics is biodegradable modeling Performance is the most excellent in material, simultaneously because its higher cost, production technology is complex, also in the market starting stage.It is raw Although superiority that object degradative plastics has other plastics to be difficult to compare: biological degradability, but they also have and are difficult in itself gram The shortcoming of clothes, such as declined comparatively fast by shearing force melt elasticity, i.e., shearing force is thinning, weakens melt strength, no It can guarantee the shape and mechanical property of moulded products.

Extruder belongs to one of type of plastics machinery, including conical double screw extruder, and conical double screw extruder is used In preparing plastic master batch, however, existing extruder can not adjust spiral shell cylinder pressure；Plastic extrusion is ineffective；It can not adjust crowded The specification of plastics out.

Injection molding machine belongs to one of the type of injection molding production and processing assembly line, and injection molding machine is for melting and being molded plastic master batch At plastic product.Injection mold is the tool for producing plastic product, and the plastics of heated thawing are injected die cavity by injection molding machine high pressure, After cooling and solidifying, formed products are obtained.The clamping product of injection formed need to be taken out using manipulator, and place product conveying unit It is transported on next process.

However, the design of injection molding machine A structure is complex, inconvenient for use, the plastics of extrusion are easy in injection molding machine solidified inside； The size of extrusion output can not be adjusted.

However, structure is complicated for injection mold B undercut machine.It according to product specification difference, cannot flexibly be adapted to, and produce Levels of precision is to be improved.

However, the injection mold with water cooling is usually direct current water cooling, water consumption is bigger；Water cooling pipeline is by mold knot Structure limitation, heat exchange area is smaller, and efficiency is to be improved.

However, the design of product pawl wrench structure is complicated, inconvenient for use, cost input is high.

However, product conveying cable architecture design is complex inconvenient for use, figure is larger, and occupied space is big, assembly and disassembly It is all more inconvenient；It can not be adjusted according to the actual condition of production.
