Extruder

Abstract

The invention discloses an extruder, and belongs to the technical field of extruder machinery. The extruder comprises a cabinet, a raw material conveying module, a melt spraying module and a winding module, wherein the raw material conveying module, the melt spraying module and the winding module are arranged in the cabinet. The extruder further comprises a waste heat recovery device and a preheating device. The raw material conveying module, the melt spraying module and the winding module are integrally designed and are arranged in the cabinet. Compared with traditional equipment, on one hand, the structure is more compact, and a work site is cleaner; and on the other hand, equipment is placed in the cabinet, and the working environment is closed, so that dust floating in the air is effectively prevented from falling onto a melt-blown fabric, and the working noise level is remarkably reduced. In addition, the waste heat recovery device is arranged, high-temperature airflow sprayed bya spinneret mold is recovered, filtered and supplied to a heating device to further heat a material conveying pipeline, and the heat energy conversion efficiency is improved. A newly-added imaging detection device also replaces a traditional manual screening mode, defects are found in time, finishing of the spinneret mold is timely, and the production efficiency is remarkably improved.

Description

Technical field [0001] This application belongs to the technical field of extruder machinery, and in particular relates to an extruder with integrated design, compact structure and excellent energy consumption management. Background technique [0002] Extruders are usually used to heat or melt fixed input materials (such as plastics, or thermoplastic materials) and extrude the materials in a flowable or molten state; the extruded or output materials are melt-blown through a spinneret die. The mesh conveyor belt is widely used in the field of mask production. [0003] The existing extruder consists of a screw conveyor, a spinneret mold and a winding component. Each component is set up separately and independently to prevent the air heater and air compressor required for the spinneret mold at the work site from being scattered. The pipeline connections are messy and the open design of the above-mentioned structure. When producing and processing melt-blown cloth, dust in the a...
