Piling type feeding pressing device of double surfacer

Abstract

The invention discloses a feed compressing device of double-sided planing laminated type, comprising a front feeding press roller and a back feeding press roller; wherein, the front feeding press roller can be rotate-supported on a front press roller supported slab, and a front press roller cylinder is hinged with the front press roller supported slab; the back feeding press roller can be rotate-supported on a back press roller supported slab, and a back press roller cylinder is hinged with the back press roller supported slab; a feeding pressing board laminated by at least a pressing board unit is arranged between the front feeding press roller and the back press roller; and the front feeding press roller and / or the back press roller are laminated by at least a press roller. The feed compressing device has the advantages of not only stable feed compressing function, without lifting or curl for the timber, but also uniform and smooth guiding function, thus the device can be widely used in various double-sided wood planing machine or four-sided milling-planing machines and other wood-working machinery.

Description

technical field [0001] The invention relates to a double-sided wood planer of woodworking machinery, in particular to an improvement of the feeding device of the double-sided wood planer. Background technique [0002] The double-sided wood planer is a woodworking machine that performs fine planing on the upper and lower surfaces of the wood that has been made into specifications wool. It can plan the specifications wool into shaped boards of different thicknesses. [0003] At present, the double-sided wood planer widely used in the wood processing industry, its feeding and feeding device is respectively provided with a front feeding roller and a rear feeding roller on the front and rear sides of the lower cutter shaft, and the front and rear feeding rollers are connected to the The cutter shafts are respectively located on the opposite sides of the processed wood or board; the front and rear feed rollers are respectively supported on the front and rear roller supports hinged...

AI Technical Summary

Problems solved by technology

[0004] However, due to the existence of the diameter of the pressure rollers on both sides of the cutting position of the lower cutter shaft, there is a "blank section" of pushing and compacting effect in a certain length area of ​​the cutting position. The feeding pressure roller in the "blank section" has no direct pressing and binding force on the processed wood, and often the wood is lifted off the worktable under the action of the vertical cutting force of the tool, especially when planing thin wood boards. The degree of lift is particularly prominent

When the head of the wood to be processed enters the pressing position of the front feeding roller, the head of the wood will be tilted up, and when the wood to be processed is separated from the feeding roller, the tail of the wood will also be lifted under the action of another feeding roller. It will warp, even if the wool is elastically arched and warped under the joint action of the front and rear feeding rollers, the supposedly straight processing surface will produce irregular concave-convex ripples. This unstable feeding and pressing effect The straightness and flatness of the wood processing surface are greatly reduced, which seriously affects the surface quality and manufacturing accuracy of the wood processing clean material

[0005] On the other hand, since the existing front and rear feed rollers all adopt an integral structure, and the contact surface between the feed roller and the wood is a rough surface, the overall rigid feed roller surface cannot conform to the rough surface of the undulating plate. , the feeding roller cannot evenly compress the rough surface of the wood. When pressing, one part must be over-pressed, while the other part has not touched the surface of the wood. The effect of the feeding roller on the wood is uneven. The feed speed is unstable, so that the wood feeding guide is not smooth, and the cutting is uneven

Especially when multiple pieces of processed wood are processed side by side, the difference in thickness of each piece of wood is unavoidable, and the unsmooth propulsion and guidance caused by this difference is more prominent, which makes the feed speed of some wood stutter and wood Excessive cutting, which seriously affects the surface processing quality and processing accuracy of wood
