Embodiment 1

[0074]Embodiment 1: A kind of manufacturing method of hollow medium density fiberboard, comprises material preparation, fiber separation (cooking, thermal grinding), fiber treatment (application of melamine modified urea-formaldehyde resin glue, paraffin water repellent, drying), fiber base board laying slab preloading, slab longitudinal trimming, horizontal sawing, slab transportation, use one or several sets of long bar loading devices, and equip a long bar positioning device to place several steel long bars horizontally or Place it vertically and press it into the base plate, and send the base plate pressed into the long bar to be leveled or not leveled and sent to a multi-layer hot press for hot pressing. The hot pressing process is carried out according to the process parameters of conventional medium density fiberboard. The time can be appropriately shortened to take into account that the heat transfer of the long steel bar accelerates the solidification speed of the plat...

Embodiment 2

[0075] Embodiment 2: The method of putting in the long bar is to use the long bar inserting device to insert the long bar into the base plate and cooperate with the long bar positioning device. Others are with embodiment 1.

Embodiment 3

[0076] Embodiment 3: the method for putting into long strips is that the fiber pavement is made into approximately half of the fiber slab bands, after pre-pressing, longitudinal trimming and transverse sawing, some slabs are used as the lower slabs, and some The slab is used as the upper slab, and several long steel bars are placed on the lower slab with a long bar loading device. The long bars are large at one end and small at the other end. The size of the long bars is coated with mineral oil. Long bar positioning device, and then use the upper blank plate transfer device to transfer the upper blank plate to the lower blank plate on which the long bar has been placed, and form a whole blank plate. The upper blank plate receiving device is a trolley or a belt conveyor belt Push the flat plate of the slab, pass the slab conveyor and the transition plate-the slab conveying line, send the slab to the multi-layer or single-layer hot press for hot pressing, press it into a slab, re...

Abstract

The invention relates to a method for manufacturing hollow medium density fiberboards and used equipment. At present, the fiberboards produced by a medium density fiberboard production line are all solid. In the invention, a part of special equipment is added in the medium density fiberboard production line so as to efficiently manufacture the hollow medium density fiberboards. The hollow medium density fiberboards can greatly save fiber materials, lighten the weight of board bodies, reduce the cost of each board, keep the good performances of the medium density fiberboards such as large breadth, fine fiber, attractive appearance, stable dimension and the like, and are of great application value in the fields of furniture, architectural decoration, wooden doors, vehicles and ships and thelike.

Description

technical field [0001] The invention belongs to the technical field of medium-density fiberboards, in particular to a manufacturing method and special equipment for hollow medium-density fiberboards. Background technique [0002] Medium density fiberboard is a board made of wood fiber or other plant fiber, applied with urea-formaldehyde resin or other synthetic resin, and pressed under heat and pressure. Usually, the original thickness exceeds 1.0mm and the density is 0.45-0.88g / cm 3 , and other suitable additives can also be added to improve the properties of the board. [0003] Dry-laid medium density fiberboard is the mainstream production process of medium density fiberboard in the world today. Its main process steps are: [0004] Material preparation→fiber separation (cooking, hot grinding)→fiber treatment (waterproofing, sizing, drying, flame retardant, anti-corrosion, anti-mildew, etc.)→pavement→blank pre-pressing→blank longitudinal trimming and / or horizontal sawi...
