Fully automatic pulp molding multi-station equipment and production process

Abstract

The invention belongs to the field of pulp molding product production equipment in a papermaking technique. Full-automatic multi-station integrated pulp molding equipment comprises an electric-heat conduction oil universal heating device, a steam heating device, a pulp chest homogenizing device, an adsorptive molding device, hot-press sizing devices, a first kind product collection device not needing stacking and a second kind product collection device capable of automatically conducting stacking; a groove is formed in a molding template of the molding device, an airflow dispersion cover plate is installed over the groove, an airflow main pipeline is vertically installed, a deckle edge spraying and template cleaning device is independently installed, heating plates of the molding devices are fixed to an upper molding template and a lower molding template through heat insulation plates, the upper molding template achieves multi-point pressurizing through a pressure stabilizing frame, the lower molding template is fixed to a transverse tackle, and heat deformation of the heating plates is effectively controlled by the molding templates. The equipment is suitable for large-scale production of pulp molding products, few molds are used, and the molds are unified and easy to replace.

Description

technical field [0001] The present invention relates to the production equipment of pulp molded products in papermaking technology, especially relates to a high-quality pulp molded product molding, shaping, collection technology and process, and provides a reasonable shaping and molding matching method-automatic pulp mold Plastic multi-station integrated equipment and production technology. Background technique [0002] At present, people's awareness of environmental protection is getting stronger and stronger. It is an inevitable trend for the future development of packaging to replace traditional foam and plastic products with pulp molded products. The raw materials used in pulp molded products are completely recyclable plant fiber pulp and waste paper pulp. The general production process of pulp molded products is: raw material - pulping - pulping - molding - transfer - shaping - collection - packaging. The slurry used needs to use a pulper to dissolve the fiber in wate...

AI Technical Summary

Problems solved by technology

[0012] 2. When the mold is heated, the mold and the cast aluminum template will produce large heating deformation, resulting in a high scrap rate, generally greater than 5%

At the same time, the amount of deformation prevents the equipment from producing high-quality pulp molded products

[0013] 3. Tableware pulp molding products require high density, smooth surface and high setting pressure, which cannot be achieved by traditional setting mechanisms.

[0014] 4. The formwork on the finalized shape needs to bear a large thrust and needs translational movement, resulting in complex structure and high cost

[0015] 5. Both the upper and lower templates for shaping need to do translational movement, which makes it difficult to control the position accuracy of the upper and lower templates for shaping, and it is prone to dislocation of the upper and lower molds
