Marrow-bend small dimension wood skinning knife

Abstract

The invention discloses a marrow-bend small dimension wood skinning knife. The marrow-bend small dimension wood skinning knife is used for solving the problems that skinning rate of small dimension wood with large marrow-bend is low, a skinning knife can be fast rusted due to abrasion, the service life of the skinning knife is short and assembly and dismantling and sharpening of the skinning knife are troublesome when skinning is carried out by a raw wood skinning machine. The marrow-bend small dimension wood skinning knife is composed of a knife arm (1) and a blade (2). The marrow-bend small dimension wood skinning knife is characterized in that a gear seat (3) is machined on the floating end of the knife arm (1), the blade (2) is arranged on the gear seat (3) in a fastening mode through a bolt (7) and a nut (8), two cutting edges (4, 4') are machined on the blade (2), the back side of the blade (2) is an installation protrusion surface (5) and an installation groove (9) is machined in the installation protrusion surface (5), the installation protrusion surface (5) is made into an arc around a fixing shaft (11), the radius of the arc is R, the fixing shaft (11) is parallel to the feeding direction of raw wood, an installation concave surface (6) is arranged on the surface of the gear seat (3) and an installation through hole (10) is formed in the gear seat (3), the installation concave surface (6) of the gear seat (3) is made into an arc around the fixing shaft (11), and the radius of the arc is R, and the fixing shaft (11) is parallel to the feeding direction of the raw wood.

Description

Technical field [0001] The invention relates to a log peeling device and a peeling knife, especially a floating type peeling knife in a ring type peeling device. technical background [0002] The small-diameter and short timber residues produced by felling and thinning in forest areas have many specifications, large quantities, and a wide range of distribution. At present, the ring peeling machine is usually used for peeling. However, the peeling knife on the peeling machine has problems such as low peeling rate, poor quality, and fast cutting edge wear when performing small-diameter wood with large marrow bends. Therefore, solving the problem of rapid wear of the peeling knife, reducing the tool change time, increasing the service life of the peeling knife, and improving the quality of the peeling quality of the bent wood are the key to improving the quality of the peeling of small diameter grades. [0003] At present, there is no skinning knife that can realize all the features...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that when peeling on the log peeling machine, the peeling rate of small-diameter wood with a large pith curve is low, the peeling knife wears and becomes blunt quickly, the service life of the peeling knife is short, and the loading and unloading of the peeling knife is troublesome. question
