Description
Technical field
The present invention relates to the technical field of extruder, and in particular to it is a kind of can Rapid Cleaning extruding machine barrel.
Background technology
The situation for needing to change processing different resins and product is often encountered by the enterprise for being engaged in extruded product processing.One
Extruder processed what rare thing three or more different products are not in 24 hours.Change process can be one
The change of kind of color, and use be still identical matrix resin.Or be changing into from a kind of resin another entirely different
Resin.It is also frequent thing to spend 30-60 minutes change.Therefore, two kinds of resins of processing are changed daily needs 1-2 small
When downtime and produce substandard product etc..It will be apparent that this will influence the profit margin of enterprise's processing business.
Above-mentioned situation it is critical that how to obtain time-consuming short and effectively complete the melt between machine barrel and screw rod
Replace.Generally there are two kinds of approach of chemical cleaning method and physical cleaning method.Chemical cleaning method, is exactly do not take screw rod and machine barrel apart clear
Lotion squeezes, and loading hopper adds chemical, rotary screw, and cleaning agent promotes the melt between machine barrel and screw rod to be arranged from front end
Go out；Chemical cleaning method needs to use auxiliary agent and Special cleaning material, and scavenging period is longer, and the waste material after cleaning can only be outwelled in vain,
Substantial amounts of waste is caused, and environment can be polluted, cleaning performance is nor ideal.Also have and be not added with the clear of cleaning agent
Method is washed, such as Jiangsu Injelic Precision Mould ＆ Plastics Co., Ltd. invention disclosed patent CN102514146A discloses a kind of note
Molding machine barrel screw rod Rapid Cleaning method, first adds bulky grain plastics preformed, retreats screw retreats to certain distance manually
To extreme position, with highest firing rate by the plastic injection in barrel.So 2-4 times repeatedly, until barrel and screw rod cleaning are dry
Only.Core concept is to back to extreme position so that being filled with a certain amount of air in barrel, when projecting at a high speed, and air is squeezed with plastics
Also good cleaning action can be thus played while pressure with screw rod outer surface and material tube inner wall face extrusion friction.But spiral shell
The molten resin of bar surface adhesion is difficult to be removed with the method, and cleaning performance is only applicable to the small resin of adhesion.
Physical cleaning method needs first to take screw rod, machine barrel apart is cleaned again, is wasted time and energy, inefficiency generally requires 12
Hour, and the working strength of operating personnel is big.The patent of invention of Dalian Rubber Plastic Machinery Co
CN102366996A discloses novel barrel device, the Hafu-type machine barrel fastened using one end around the folding of pivot 2, another terminal bolt
1, left half machine barrel and right half machine barrel are connected by the screw mandrel machine barrel mechanism of side respectively, and machine barrel is hinged on frame side, screw mandrel one
End is hinged on the machine barrel of left/right half, and other end threaded engagement is fixed with ratchet spanner 5 in machine barrel, on screw mandrel, by rotating spine
Wheel spanner 5 drives screw mandrel rotation, and screw mandrel is screwed in machine barrel, so as to drive the machine barrel of left/right half to open, maximum can be opened to 60 °, open
Conjunction process does not need any lifting tool, only needs an operative employee to be easily accomplished.But the above method is limited only to single screw rod
Machine barrel.
Thus, it is desirable to design a kind of screw extruder, it should have the convenient structure for carrying out surveying bottom cleaning, facilitate behaviour again
Make so that cleaning efficiency is high.
