Abstract
The utility model discloses a kind of plastic extruding screw, comprise screw rod core, and being coated on the thread segment of described screw rod core circumference, described thread segment along described screw mandrel to being divided into two sections that at least mutually dock, and is butted into complete screw thread by butted line after the docking of described thread segment; Every section of described thread segment is all along described screw rod core diameter to being divided at least two pieces and the complete thread segment that is mutually spliced.This utility model is by being internal layer screw rod core and outer thread segment by screw design, and thread segment is divided into some sections vertically, and every section of thread segment is radially spliced by polylith, the replacing of relevant position thread segment can be carried out so targetedly for thread damage section, screw rod replacement cost can be reduced drop into, and change conveniently, can effectively enhance productivity.
Description
Technical field
The utility model relates to a kind of plastic extruding screw.
Background technology
In polymer production, screw rod not only realizes feed effect, and realize the immixture of material, therefore the problem of screw rod wearing and tearing is very outstanding, add factor that is overheated, the aspect such as foreign matter enters, cooling strain, machinery, the spoilage of screw rod is very high, if can not carry out replacing process in time, then can cause whole production process and have a strong impact on.
The screw rod of prior art is mostly the fixed integrative-structure of whole section, there is following defect in it: then must change whole screw rod when the thread damage of screw rod section, not only cause the significant wastage of equipment and materials, add production cost, and change inconvenient, be unfavorable for production that is steady and serialization, not only have impact on production efficiency, and be unfavorable for obtaining high-quality product.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of plastic extruding screw, to realize the efficient replacing of screw rod and to reduce screw rod cost input.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of plastic extruding screw, comprise screw rod core, and being coated on the thread segment of described screw rod core circumference, described thread segment along described screw mandrel to being divided into two sections that at least mutually dock, and is butted into complete screw thread by butted line after the docking of described thread segment;
Every section of described thread segment is all along described screw rod core diameter to being divided at least two pieces and the complete thread segment that is mutually spliced.
Wherein, described thread segment coordinates the locating slot of described screw rod wicking surface to locate by the locating piece of inner side, then completes seamless spliced by the mutual adhesive of magnet of thread segment Mosaic face described in polylith.
Pass through technique scheme, a kind of plastic extruding screw that the utility model provides, it is by being internal layer screw rod core and outer thread segment by screw design, and thread segment is divided into some sections vertically, and every section of thread segment is radially spliced by polylith, the replacing of relevant position thread segment can be carried out so targetedly for thread damage section, screw rod replacement cost can be reduced and drop into, and change conveniently, can effectively enhance productivity.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Referring to figs. 1 to 3, the plastic extruding screw that the utility model provides, comprise screw rod core 21, and be coated on the thread segment 11 of screw rod core 21 circumference, thread segment 11 is along the axial thread segment 11 being divided into multistage and mutually docking of screw rod core 21, and thread segment 11 is butted into complete screw thread 12 by butted line 13 after docking;
With reference to figure 2, every section of thread segment 11 is all divided into three pieces of symmetrical thread segments 11 being also mutually spliced complete along screw rod core 21 radial direction; With reference to figure 3, every section of thread segment 11 is all divided into two pieces of symmetrical thread segments 11 being also mutually spliced complete along screw rod core 21 radial direction.
Wherein, thread segment 11 coordinates the locating slot on screw rod core 21 surface to locate by the locating piece 22 of inner side, then completes seamless spliced by the mutual adhesive of the magnet 23 of polylith thread segment 11 Mosaic face.
A kind of plastic extruding screw that the utility model provides, its screw rod core 21 and outer field thread segment 11 by by screw design being internal layer, and thread segment 11 is divided into some sections vertically and there is complete screw thread 12 after being docked by butted line 13, and every section of thread segment 11 is radially spliced by magnet 23 adhesive by polylith, the replacing of relevant position thread segment 11 can be carried out so targetedly for thread damage section, screw rod replacement cost can be reduced drop into, and change conveniently, can effectively enhance productivity.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of above-described embodiment, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
