Wood fiber extruding injection forming process and device

Abstract

The invention discloses a wood fiber extruding injection forming process and device. The process comprises the steps of stirring, feeding, extruding, buffer stock bin operation, plunger feeding, die pressing and die stripping. In the process, the related wood fiber extruding injection forming device comprises a stirring unit, a feeding and extruding unit and a forming unit. The feeding and extruding unit comprises an extruder and a plunger type cylinder. The forming unit comprises a distribution unit, an upper die and a lower die, wherein the upper die and the lower die can be separated. By adopting the method and cooperatively using the extruding injection forming device, the quality defects such as surface softness and insufficient density due to the fact that local corners of products are not filled densely because of the low random stacking density and poor liquidity of wood fibers are effectively avoided, so that the hardness is reached while the density is uniform, and production of large plates can be achieved.

Description

technical field [0001] The invention relates to the technical field of wood deep processing, in particular to a wood fiber extrusion injection molding process and device. Background technique [0002] With the progress of society and the continuous improvement of people's living standards, the consumer demand for high-end wooden furniture is also increasing. With its beautiful vision and comfortable touch, traditional solid wood furniture has an absolute advantage in high-end home consumption. However, solid wood furniture has the following problems: (1) Lack of wood resources, traditional solid wood furniture needs to consume a lot of raw wood materials, my country is currently facing a shortage of wood resources; (2) The utilization rate of logs is low, and the utilization rate of logs in solid wood furniture is only about 35%. , which further exacerbated the massive consumption and waste of wood resources; (3) The production efficiency is low, the production process of tr...

Problems solved by technology

However, solid wood furniture has the following problems: (1) Lack of wood resources, traditional solid wood furniture needs to consume a lot of raw wood materials, my country is currently facing a shortage of wood resources; (2) The utilization rate of logs is low, and the utilization rate of logs in solid wood furniture is only about 35%. , which further exacerbated the massive consumption and waste of wood resources; (3) The production efficiency is low, the production process of traditional solid wood furniture is relatively complicated, and the current production equipment cannot meet the needs of high-efficiency production, especially the high-end European-style furniture. Carving to complete, on the one hand greatly increased labor costs, on the other hand lead to extended manufacturing cycle

Existing wood fiber products are formed by hot pressing. Due to their poor filling and fluidity, some quality defects such as softness and uneven filling of the corners will occur on the surface of the product, and it is impossible to obtain large-format boards.
