Description
Technical field
This utility model relates to strip polymer fabrication technique field, is specifically related to the feeding structure of a kind of extruder.
Background technology
Hollow molding is by extruding or inject prepared, to be still in plastifying state tubulose or laminar blank material trend is fixed
In mould, it is passed through compressed air at once, forces base material to expand and be affixed on mold cavity wall, de-after sizing to be cooled
Mould, obtains a kind of processing method of required hollow product.Be suitable for hollow molding plastics be polyethylene from high pressure process, low-pressure polyethylene,
PVC-U, flexible PVC, polystyrene, polypropylene, Merlon etc..According to the difference of parison formation method, hollow
Molding is broadly divided into extrusion-blown modling hollow molding and injection-blow molding hollow molding two kinds.The advantage of extrusion-blown modling hollow molding is crowded
Go out the simple in construction of machine and extrusion-blown modling mould；Shortcoming is that the wall thickness of parison is inconsistent, and the wall thickness easily causing plastic is irregular.
The advantage of injection-blow molding hollow molding is the uniform wall thickness of parison, non-trimming, owing to injection parison has bottom surface, and therefore hollow system
The bottom of product will not produce spelling and seam, the most attractive in appearance but also intensity high；Shortcoming be former used and Die price expensive, therefore
This forming method is used in the production in enormous quantities of small hollow goods, does not has extrusion-blown modling hollow forming method on using
Extensively.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that low cost, service life are long, and is easy to maintenance and changes
The feeding structure of extruder.
In view of the problems referred to above of prior art, according to an aspect of the present utility model, ask for solving above-mentioned technology
Topic, this utility model by the following technical solutions:
The feeding structure of a kind of extruder, it includes that charging box, feed cylinder and feeding spiro rod, described charging box send with described
Barrel connects, and described feeding spiro rod is positioned at described feed cylinder, described feed cylinder outer wall is provided with heater, described feeding
Being provided with mixing device on screw rod, described mixing device is set to 2, and described mixing device includes dead ring and batch mixing sheet, institute
Stating dead ring to be fixedly installed on described feeding spiro rod, described batch mixing sheet is arranged on described dead ring, and described batch mixing sheet sets
Be equipped with circular port, the screw thread sheet on described feeding spiro rod be subsection setup and be stuck in feeding spiro rod body groove in, two sections of spiral shells
Stricture of vagina sheet is connected by spot welding, and described screw thread sheet is fixed also by spot welding with described feeding spiro rod body, the outside of described screw thread sheet
Edge is provided with wear plate.
In order to this utility model is better achieved, further technical scheme is:
According to an embodiment of the present utility model, described heater uses electric heater.
Compared with prior art, one of the beneficial effects of the utility model are:
The feeding structure of extruder of the present utility model, is that subsection setup being stuck in send by the screw thread sheet on feeding spiro rod
In the groove of material screw body, two sections of screw thread sheets are connected by spot welding and described screw thread sheet also leads to described feeding spiro rod body
Cross the mode that spot welding is fixing, facilitate the replacing stating screw thread sheet on feeding spiro rod, it is to avoid be to feeding spiro rod overall more
Change, saved cost, improve the life-span of whole feeding structure by the wear plate arranged.
