Description

Technical Field

[0001] The invention relates to the technical field of wood board processing, in particular to a putty scraper for wood board processing. Background Art

[0002] The wooden boards used in furniture production need to be treated with plastering after puttying to ensure that the surface of the wooden boards is flat and smooth. The puttying and plastering operation is generally completed by a plastering machine. The wooden boards are fed by the board feeding conveyor roller at the front end of the plastering machine, and the multiple sets of upper and lower pressure rollers inside the plastering machine ensure the smooth operation of the wooden boards. However, in the actual working process, when the tail of the wooden board passes through the board feeding conveyor roller or when plastering some shorter wooden boards, there is a certain gap between the adjacent sets of upper and lower pressure rollers, which causes uneven force on the wooden board, causing shaking and warping, which may cause damage to the wooden board in severe cases. At present, the upper and lower rollers of the plastering machine are generally fixedly installed, and the gap between the upper and lower rollers cannot be adjusted. This means that the plastering machine can only perform plastering operations on wooden boards of fixed thickness, and cannot be used normally when facing wooden boards of other thicknesses, resulting in poor applicability of the plastering machine.
