Problems solved by technology

[0010] In order to overcome the shortcomings of slow melting rate and low productivity of the single-screw extruder, the present invention makes full use of the fact that the polymer is easily plastically deformed under stress, generates heat under alternating stress and friction, softens at high temperatures, melts, and melts mainly rely on The heat generation characteristics

Embodiment Construction

[0033] As shown in Figure 1, the screw rod (2), rotating disk (5), and rotating shaft (11) are an integral part, supported and fixed on the frame (8) by thrust bearings (9) and ordinary bearings (10) . Fixed disk (4), screw barrel (3) are an integral part, installed on the rotating disk (5), screw rod (2) passes through the center of screw barrel (3) and fixed disk (4), fixed disk ( 4) It is fixedly connected with the frame (8), and the hopper (1) is installed on the screw barrel (3). Volute (6) is installed around rotating disc (5), and its lower end is closed with frame (8), (the present example volute (6) and frame (8) are integral parts), and its upper end and fixed disc ( 4) closed, the die head (7) is installed on the outlet of the volute (6).

[0034] The gap between the fixed disk (4) and the rotating disk (5) can be controlled by placing a standard plate between the two disks when the fixed disk (4) is assembled on the rotating disk (5). The centering of the screw ...

Abstract

A slotted disk type high-speed extruder is composed of the solid delivering segment consisting of material feeding hopper and screw pump, the material calendering-smelting segment with slotted grinding disk structure, the molten material gathering-delivering segment with volute pump, moulding head, machine frame, and motor. Its advantage is high smelting and extruding speed.

Description

Technical field: [0001] The present invention relates to a machine for melt processing of polymers. Background technique: [0002] At present, the general-purpose single-screw extruder is composed of a screw, a screw barrel, and a die head. The screw is generally divided into a feeding section, a compression section, and a metering section (some also have an exhaust section and a mixing section). The main difference between each section is that Depending on the shape, size, helix angle, and number of screw edges, the principle of the single-screw extruder is: the screw rotates, the screw barrel is fixed, and the material is pushed forward under the action of the screw force, and at the same time the material passes through the screw barrel and screw. The friction and the viscosity inside the material generate heat, gradually melt and send out from the die. [0003] We hope that the screw extruder has the highest extrusion rate as possible, and generally adopt the following ...
