Description

Glued wood honeycomb panel and molding process The invention belongs to the technical field of composite honeycomb sandwich structure, and particularly relates to a molding process for compositeing wood veneer or plywood with weft wood fabric folded honeycomb core.

The currently known technology is: Honeycomb sandwich composite material has been the focus of research in the field of composite application development due to its series of advantages such as reasonable structure, light weight, high strength, and material saving. The skin and clip of the layer structure have been developed up to now. There are many kinds of core materials. Commonly used skin materials include aluminum alloy sheets, titanium alloy sheets, glass steel sheets, wood plywood, fiberboard, inorganic composite sheets, plastic sheets, fiberglass cloth, aramid cloth, cotton cloth and paper, etc. Commonly used honeycomb cores are paper honeycomb core, FRP honeycomb core, plastic honeycomb core, aluminum alloy honeycomb core, aramid honeycomb core, etc., and various honeycomb composite sandwich structures can be developed by compounding each skin with different honeycomb core materials. Materials, the most widely used products are mainly paper honeycomb cores, various wood-based panel honeycomb cores, glass steel and FRP honeycomb cores and aluminum and aluminum honeycomb core sandwich structures.

ί

Various paper honeycomb core sandwich structural materials are limited in water resistance and moisture resistance, have limited puncture strength, and are limited in application range. Because of the high price, the laminated structure materials such as FRP honeycomb, aluminum honeycomb, and ray honeycomb are not widely used. There are also unit-type intermittent double-shelf molding, which has high labor intensity and low efficiency, but the equipment investment is small, and the size change is flexible, which can meet the needs of the single product. How to find a material that combines the advantages of paper-based unit composite molding with good performance and low price.

The object of the present invention is: a method for forming a composite structure of a wood veneer or a plywood honeycomb sandwich by using a wood single-ply or plywood as a molding method for the composite of the skin material and the weft wood fabric folded honeycomb core. The wood material has a wide range of raw materials, strong recyclability, high compressive strength, good reproducibility and low price. It is a combination of angular flexible fibers and weaving or weaving of warp and weft chips. The mechanical properties of wood strips are different, the molding process is simple, and the products can be widely used. Description

It is used in the field of wood-based panel applications, building materials, packaging materials, etc., as well as all other areas where the demand for sandwich composites is required.

The technical method adopted by the invention to solve the technical problem is as follows: Firstly, a reel weft wood fabric is mounted on the reel upper frame; the weft-oriented wooden glass cloth is introduced into the transverse coating of the rubber coating mechanism by the front guiding roller The roller is laterally coated with a longitudinally stripped strip of glue on the weft wood glass cloth by the longitudinal web or longitudinal groove of the rubberized roller, and a set of glue coating mechanism is provided on both sides of the adhesive cloth. The two sides of the weft wood glass cloth are alternately coated with glue, the length of the alternating is equal to the length of the future folding, the alternate point is equal to the 'folding point, the switching between the speed of the weft wood glass cloth and the rubberizing roller and the glue coating mechanism needs to be realized. Synchronous control, it should be ensured that the adjacent side of the folded surface is coated with the strip of the width of the wooden weft strip in the transverse direction of the weft strip. The width between the strips is 4 times of the width of the strip, and the adjacent strips of the coated strip are staggered. One side of the strip is accurately placed in the middle of the two adjacent strips; the coated latitudinal glass cloth is heated by the rear guide roller as needed, and then guided by one or more guide rolls. Driven by the fabric folding mechanism to reciprocate the folding table according to the designed length The upper folding is performed by the belt cloth mechanism and the set of folding head clamping mechanisms on the left and right sides to achieve precise folding and positioning. The stacking head clamping mechanism is a pair of front and rear fits to ensure that the wooden strip is clamped at the same time. The piece is pressed against the folding table, and the pressure is maintained until the other lamination clamping mechanism is depressed and then released, and the lower 7 layers of cloth fed by the cloth feeding mechanism are executed, and the other side is always clamped until The side is pressed down again and then released, and the next layer of cloth carried by the belt cloth mechanism is opened, so as to be alternately cycled and folded; the folding mechanism includes a stacking clamping mechanism, a belt cloth mechanism, and the folding table includes other An auxiliary mechanism for ensuring effective cooperation of the various structures; folding to a desired thickness of the weft wood glass cloth to cut into a honeycomb core folding block, which is carried away by a folding table or a conveyor belt on the folding table, while allowing the folding table to continue folding The next honeycomb core folding block, the honeycomb core folding block is sent to the pressurization or pressurization on demand, and is heated and solidified into the latitudinal honeycomb core original plate; the honeycomb core original plate is perpendicular to the weft wood strip according to the honeycomb height Cutting into the wood of the core strip poultry bee honeycomb core width of the strip is equal to the length of the folded; strips meet the requirements of the honeycomb core can be used as a cell pellet, or by adhesive into a honeycomb fight pellets, for Description

For the unit honeycomb core; if the width is not enough, it needs to be laterally butted one or more times to the required width, and finally becomes a unitized wood honeycomb pellet for the length and the length; the unit honeycomb core is stretched to form a chip The wooden honeycomb wood honeycomb core with the erected lines is immersed and fixed by the spray glue to be set as the wooden bee core board; the unit type wooden honeycomb core board is coated with two sides of single or multi-layer wood veneer or plywood on the upper and lower sides as needed. It is a slab of glued wood honeycomb panel with no edge seal on all sides; it can be composited to form a unitized glulam honeycomb panel by heating, pressing or heating and pressing on demand; it can be glued without wood honeycomb core board, and directly by veneer wood veneer The glued or invaded rubber is pressed and composited; the honeycomb core and the veneer veneer can be jointly invaded and pressed to be composited; the veneer honeycomb panel can be a flat plate or a curved panel. Glued wood honeycomb panels can be used as partition plates, countertops, furniture panels, partition panels, and other unit panels; various glued wooden honeycomb doors can be pressed out by framed, molded or connected blocks; It can also be used to make trays, furniture parts, hulls, container boards, compartment boards, etc.: 'The core block can be processed to meet the needs of the concave and convex mezzanine structure.

The invention has the beneficial effects that: the wooden veneer honeycomb panel greatly reduces the amount of wood used, and can be conveniently decorated with various veneer materials and can be used as a wood veneer specially processed by milling, sanding or the like. The surface coating material of the composite sandwich honeycomb panel realizes the decorative layer with wood grain, which maximizes the material utilization efficiency, realizes the maximum production efficiency, and has very good economic and social benefits.
