Abstract

The invention relates to a large and bulky paper pulp die-pressing process, which includes the following steps: a pulp box loaded with paper pulp is arranged under a forming unit, a paper pulp agitation mechanism is arranged at the bottom in the pulp box, the recess of a forming female die is upward, and moreover, the forming female die can be driven by a driving mechanism to move down into the pulp box, and thereby is immerged into paper pulp; a vacuumizer is utilized to vacuumize the forming female die, so that a wet green is formed; the forming female die upwardly gets close to a male die, the wet green is transferred, the male die brings the wet green to move onto a shaping unit, and the wet green is heated and shaped. The process disclosed by the invention can prepare bulky and large-sized vegetable fiber die-pressed products, the cost is low, and the rate of finished products is high.
大型厚体纸浆模压工艺,步骤如下:在成型设备的下方设置装有纸浆料的浆箱,浆箱的内侧下方设有纸浆搅拌机构,成型凹模的凹口向上并在驱动机构带动下下行至浆箱内,使成型凹模浸入纸浆料内;利用抽真空装置对成型凹模抽真空,形成湿胚;成型凹模向上与凸模合模并转移湿胚,凸模带动湿胚移动到定型设备上,对湿胚进行加热定型。本发明的工艺可制备厚体大规格植物纤维模压制品,成本低,成品率高。
