Embodiment 1

[0014] A plastic wood material extrusion process, the production line is: feed material, extruder extrusion, discharge cooling, cutting, finished product collection. The two processes of feeding and extrusion of the extruder are controlled. When feeding, turn on the heater, mix the plant fiber powder and filler, heat up to 150°C for drying, and then cool down to 115°C after drying. The speed should be slow. Every time the temperature rises and falls by 10°C, drain the water and discharge steam once. After cooling down to 115°C, add other materials and stir evenly; when the extruder is extruded, the temperature control of the extruder barrel , and the temperature control of the extrusion molding die, the temperature at the barrel of the extruder is controlled at 150°C, the temperature of the die at the extrusion port is also controlled at 150°C, and the air pressure control at the feed is also very critical. To produce hollow plastic wood profiles, the air pressure Controlled a...

[0016] A plastic wood material extrusion process, the production line is: feed material, extruder extrusion, discharge cooling, cutting, finished product collection. The two processes of feeding and extruder extrusion are controlled. When feeding, turn on the heater, mix the plant fiber powder and filler, heat up to 150°C for drying, and then cool down to 120°C after drying. The speed should be slow, and every time the temperature rises and falls by 10°C, drain the water and steam once, and after cooling down to 120°C, add other materials and stir evenly; when extruding the extruder, the main thing is to control the temperature of the extruder barrel. , and the temperature control of the extrusion mold, the temperature at the barrel of the extruder is controlled at 150°C, and the temperature of the mold at the extrusion port is also controlled at 150°C to produce solid wood-plastic profiles, and the air pressure at the feed is controlled at 35MPa.

Abstract

The invention discloses a control method of a plastic-wood material extrusion molding process. The control method mainly controls the feeding procedure and the extrusion procedure of an extruding machine. The feeding control method comprises the steps that a heater is started; plant fiber powder and filler are mixed and then are heated by 10 DEG C and dried; the mixture is cooled by 10 DEG C after being dried; then water and steam are exhausted; other materials are added after cooling and are stirred evenly; in the extrusion forming process of the extruding machine, the temperature at a screw tube of the extruding machine and the temperature of an extrusion outlet mould are controlled to be 140-150 DEG C, and the air pressure at the feeding position is controlled to be 20-40 MPa. The plastic-wood material extrusion assembly line has strict specifications and standard operations in the production process; the rejection rate of products is reduced; the qualities of products produced at the same assembly line are uniform, so that material waste and labor cost are reduced and efficiency is improved.

Description

technical field [0001] The invention relates to a processing technology of a decorative material, more particularly to an extrusion molding technology of a plastic wood material. Background technique: [0002] The traditional production line of plastic wood profiles is: feeding, extrusion by extruder, cooling of output, cutting, and collection of finished products. The traditional process does not have a good temperature control standard in the process of feeding, extruding machine extrusion, etc., which will lead to unstable product quality, high product scrap rate, and too fast discharge, and too fast cooling speed , easy to form internal stress, and then easy to crack. Invention content: [0003] In view of the above problems, the present invention provides a controllable and standard wood-plastic material extrusion process that can improve the stability of product quality, reduce the scrap rate of products. [0004] The present invention is achieved through the follo...
