Folding type milling foot pressing apparatus of double surfacer

Abstract

The invention discloses a double-sided and stacked planing pressure device which comprises a knife shaft seat, an upper knife shaft arranged on the knife shaft seat, a front pry bar and a back pry bar which are respectively arranged at the front side and the back side of the upper knife shaft; the knife shaft seat can be supported on a fixing knife bed in a sliding manner; the front pry bar is stacked by at least one front pry bar unit, and the back pry bar is stacked by at least one back pry bar unit. The knife shaft seat can be supported on the fixing knife bed in a sliding manner by a knife shaft sliding mechanism; one end of the knife shaft seat is provided with a wedge-shaped locating mechanism, and the other end of the knife shaft seat is provided with a knife bed locking mechanism. The stacked planing pressure device has the advantages of stable impacting and restraining effect and good wood attaching performance, can avoid the occurrence of warping and irregular concave-convex ripple in the processed wood, and can be widely applied in various wood planing machines.

Description

technical field [0001] The invention relates to a double-sided wood planer of woodworking machinery, in particular to an upper cutter shaft planing and pressing structure of the double-sided wood planer. Background technique [0002] The double-sided wood planer is a woodworking machine that finely processes the upper and lower surfaces of the wood made of wool with specifications. It can plan the wool with specifications into clean shaped boards of different thicknesses. The double-sided wood planer widely used in the wood processing industry includes an upper planer shaft, a lower planer shaft, and a feeding and pressing device corresponding to the lower planer shaft, so as to realize the planing process of the upper and lower surfaces of the specified wool. [0003] When the existing double-sided wood planer works, the wood is clamped and pushed by the front and rear feeding pressure rollers of the feeding and pressing device to overcome the planing resistance of the cutt...

AI Technical Summary

Problems solved by technology

Moreover, this integral rigid front and rear presser foot structure cannot adapt to the undulating rough surface of the board and the thickness difference of each wood, so that the presser foot cannot actually press evenly and constrain the surface of the wood, and it must be partly pressed when pressing. Excessive pressure, while the other part has not yet touched the wood surface, resulting in poor bonding between the presser foot and the wood, uneven compression and restraint, aggravating the appearance of irregular concave-convex processing ripples, seriously affecting the surface quality and processing of wood precision
