Abstract
The invention provides a screw for a pelletizer. The screw for the pelletizer comprises a screw body, wherein threads are arranged on the screw body. The screw for the pelletizer is characterized in that the threads are dual threads; a cavity is arranged inside the screw body; a straight rod and a heating wire which is wound on the straight rod are arranged inside the cavity; two groups of threads of the dual threads are different in height; the threads on the screw body adopt the dual threads; two groups of threads of the dual threads are different in height, so that the screw can well play a stirring role on old PC (polycarbonate) and ABS (acrylonitrile-butadiene-styrene) particles when rotating; and meanwhile, the straight rod and the heating wire are arranged inside the screw. The heating wire generates heat when the screw for the pelletizer is used; and the heat is transferred to the old PC and ABS particles through the screw body and the threads, so as to play a good heating role on the particles. Even mixing of the cold PC and ABS is facilitated.
Description
Technical field
The invention belongs to the device of plastic processing field, relate in particular to a kind of comminutor screw rod.
Background technology
At present, the required material of the high-end household electrical appliances skeleton of domestic making adopts the PC/ABS raw material of Korea S's import to make more, and cost is very high.So some producer adopts the PC, the ABS material that reclaim to carry out the high-end household appliances skeleton of twice-modified preparation material.But old PC, ABS cause problems such as impact resistance descends, the change of product shrinkage factor is big owing under the condition of long-term positive light and heat out of doors, degraded is in various degree arranged.But it is inhomogeneous batch mixing often to occur when being to use existing single screw pelletizer that old PC, ABS are handled, and causes product impact, the tensile property produced at last relatively poor, can not meet the demands.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of comminutor screw rod, comprise the body of rod; the described body of rod is provided with screw thread; it is characterized in that described screw thread for two screw threads, is provided with cavity in the described body of rod, be provided with straight-bar and the heater strip that is wrapped on the straight-bar in the described cavity.
The height difference of two groups of screw threads of described pair of screw thread.
Beneficial effect of the present invention is: the screw thread on the body of rod adopts two screw threads, and the height difference of two groups of screw threads of two screw threads makes screw rod can play stirring action to old PC, ABS particle better when rotating; Straight-bar and heater strip are set in screw rod simultaneously, the present invention in use, heater strip produces heat, and is delivered on old PC, the ABS particle by the body of rod and screw thread, and particle has been played good heat effect, is convenient to old PC, ABS are mixed.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing:
Among the figure, 1, the body of rod; 2, screw thread; 3, straight-bar; 4, heater strip.
As shown in Figure 1, the body of rod 1 is provided with screw thread 2, and screw thread 2 is two screw threads, and the height difference of two groups of screw threads of two screw threads is provided with cavity in the body of rod 1, is provided with straight-bar 3 and the heater strip 4 that is wrapped on the straight-bar 3 in the cavity.
More than have been described in detail of the present invention by embodiment, but described content only is preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
