Embodiment Construction

[0017] Below in conjunction with the embodiment shown in the accompanying drawings, the present invention is described in detail as follows:

[0018] Instructions attached figure 1 and attached figure 2 The helical ribs in dotted lines represent the main ribs, and the helical ribs in solid lines represent secondary ribs; image 3 The double dotted line in the figure indicates the outer diameter of the extrusion screw, the dotted line indicates the bottom diameter of the solid phase tank, and the solid line indicates the bottom diameter of the liquid phase tank.

[0019] as attached figure 1 to attach Figure 4 As shown, a separate extrusion screw has a feed end 1 and a discharge end 2, and along the length direction from the feed end 1 to the discharge end 2, there are A section, B section, C section, D section, The peripheral wall of the extrusion screw is spirally extended with a main rib 3 and a secondary rib 4, the axial projection of the main rib 3 and the secondary ...

Abstract

The invention discloses a separate extruding screw, which is sequentially divided into sections A, B, C and D along the length direction from the feed end to the discharge end. The axial projection of the rib and the auxiliary rib coincides, the side of the main rib facing the feed end is the first side, the back is the second side, the side of the auxiliary rib facing the feed end is the third side, and the back is the fourth side. A solid phase tank for liquid operation is formed between the four sides, and a liquid phase tank for solid operation is formed between the second and third sides; in section B, the width of the liquid phase tank is the same, and the width of the solid phase tank is the same. The depth of the liquid phase tank gradually increases; its high-efficiency and high-speed extrusion lies in the design of the liquid phase tank and solid phase tank in the B section, which have the same width but the groove depth changes, so that the contact surface between the solid particles and the barrel can be maximized, and the barrel The heat is effectively transferred to the solid particles, the shearing effect of the screw is enhanced, the effect of plasticizing and melting the material is enhanced, and the extrusion output is increased.

Description

technical field [0001] The invention relates to a plastic extruding device, in particular, to a separate extruding screw. Background technique [0002] At present, the structure of the traditional separate extrusion screw has great disadvantages, one is the low melting efficiency, and the other is that it is difficult to increase the extrusion output. Contents of the invention [0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a separate extrusion screw, which can effectively improve the melting efficiency and increase the extrusion output. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A separate extruding screw has a feed end and a discharge end. It is sequentially divided into sections A, B, C and D along the length direction from the feed end to the discharge end. The peripheral wall of the extrusion scr...
