本发明采用的纸浆模塑制品成型工艺为真空吸浆成型法，真空吸浆成型法是纸塑制品最普及的一种方法，依据其结构不同又有三种方式：转鼓式、翻转式、往复升降式；The molding process of the pulp molded product used in the present invention is the vacuum suction molding method. The vacuum suction molding method is the most popular method for paper plastic products. There are three methods according to its structure: rotating drum, turning, and reciprocating. Lift type
转鼓式：连续性旋转生产，生产效率高，模具投资大，模具加工精度高，设备加工精度技术要求高，一套凹模配八套凸模，需用数控中心加工模具，加工周期长，投资大，由于是连续生产，适合于大批量的定型产品生产，如果盘、餐盘、酒托、鸡蛋托，对于工业模塑生产由于非标准，数量、批量小，模具投资大所以不适用。Rotary drum type: continuous rotating production, high production efficiency, large investment in molds, high mold processing accuracy, high technical requirements for equipment processing accuracy, one set of concave molds with eight sets of punches, the molds need to be processed by CNC centers, and the processing cycle is long. Large investment. Because it is continuous production, it is suitable for mass production of stereotyped products. If plates, dinner plates, wine trays, and egg trays are non-standard for industrial molding production, the quantity and batch are small, and the mold investment is large, so it is not applicable.
翻转式：返转式生产较鼓式生产效率低，适合于工业模塑中等批量及非标准的生产，但由于是一套凹模配二套凸模，需用数控中心加工模具，模具投资大，周期长。Reversing type: The reversing type production is less efficient than the drum type production. It is suitable for medium batch and non-standard production of industrial molding. However, because it is a set of concave molds with two sets of punches, the mold needs to be processed by a CNC center, and the mold investment is large , Long cycle.
往返升降式：生产效率较转鼓式低，与返转式相差不大，是目前常风的普遍使用设备，由于该设备只需一套凹模配套一套凸模，不须数控中心加工，特别适合非标准、批量小、周期快的工业包装产品，本发明所采用的就是往返升降式。Reciprocating lift type: The production efficiency is lower than that of the drum type, and it is not much different from the revolving type. It is a commonly used equipment in the current normal wind. Because the equipment only needs a set of concave molds to match a set of punches, no CNC center processing is required. It is particularly suitable for non-standard, small batch, and fast cycle industrial packaging products. The invention adopts the reciprocating lift type.
纸浆模塑制品干燥工艺：纸浆制品经碎浆、成型后，一般均含有较高水份，需经过干燥工艺，干燥工艺利用燃油(气)、电或蒸汽、热油或其他介质为热源，加热空气，将成型后的纸浆模塑制品在热空气(180￣220℃)中烘干，利用风机抽出制品蒸发出的水份，达到快速干燥的效果。Drying process of molded pulp products: After pulping and molding, pulp products generally contain higher moisture and need to go through a drying process. The drying process uses fuel (gas), electricity or steam, hot oil or other media as the heat source, heating Air, dry the molded pulp products in hot air (180~220℃), and use a fan to extract the water evaporated from the products to achieve a rapid drying effect.
纸浆模塑制品整形工艺：纸浆制品经成型、干燥后，基本定型，再用高温及较大压力进行压制，使其外形整齐美观，达到更好的坚韧性，具有更好的防震性能，整形工艺一般以电加热发热板或使用其他热介质(如导热油)加热发热板，使纸浆制品模具具有较高的温度(180￣250℃)，利用气压或液压压力，在高温、高压下压制纸托制品，达到定型效果。Shaping process of molded pulp products: After being shaped and dried, the pulp products are basically shaped, and then pressed with high temperature and greater pressure to make their appearance neat and beautiful, achieve better toughness, and have better shockproof performance. Shaping process Generally use electric heating heating plate or other heating medium (such as heat transfer oil) to heat the heating plate, so that the pulp product mold has a higher temperature (180 ~ 250 ℃), using air pressure or hydraulic pressure to press the paper support under high temperature and high pressure Products to achieve the finalizing effect.
本发明通过采用废纸、废包装等废料作为原材料并将原材料制成纤维纸浆用于制作集尘盒，实现了原料来源广泛，成本比现有塑料集尘盒制造工艺大大降低，集尘盒可完全降解，环保便捷的功能，通过采用可降解的纤维纸浆制成扫地机器人集尘盒，实现了制造出来的集尘盒在需要清理的时候直接取出更换并丢弃，免除清灰的步骤，避免清理时灰尘的扬尘，操 作方便快捷，环保健康的功能。The invention adopts waste paper, waste packaging and other waste materials as raw materials and makes the raw materials into fiber pulp for making dust collection boxes, which realizes a wide range of raw materials and greatly reduces the cost compared with the existing plastic dust collection box manufacturing process. Completely degradable, environmentally friendly and convenient functions. By using degradable fiber pulp to make the dust box of the sweeping robot, the manufactured dust box can be directly taken out and replaced when it needs to be cleaned and discarded, eliminating the steps of cleaning dust and avoiding cleaning Dust from time to time, convenient and quick operation, environmental protection and health function.
