Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a urea-formaldehyde resin adhesive density fiberboard cutting device. Background Art

[0002] Density board is called density fiberboard, which is made of wood fiber or other plant fiber, prepared by fiber preparation, applied with synthetic resin, and pressed under heating and pressure. Urea-formaldehyde resin, also known as urea-formaldehyde resin, is the initial urea-formaldehyde resin formed by condensation of urea and formaldehyde under the action of catalyst, and then formed into an insoluble and infusible final thermosetting resin under the action of curing agent or auxiliary agent.

[0003] When density boards are produced, they need to be bonded with urea-formaldehyde resin glue. The hardness of density boards is relatively high, so automated cutting equipment is required for board cutting operations. Existing board cutting equipment generally positions the boards by pressing down with a roller during processing, but there is no effective limiting mechanism during the board feeding process, which makes it inconvenient to maintain the centering state of the board, and easily leads to inaccurate processing points, affecting the quality of the finished product.
