Description

Be used for overlength timber veneer to revolve, cut all-in-one

Technical Field

The application relates to the technical field of wood slicing, in particular to a rotary shearing integrated machine for an ultra-long wood veneer.

Background

Rotary cutting machines are one of the main devices for producing plywood. The rotary cutting machine is divided into a clamping rotary cutting machine and a non-clamping rotary cutting machine, wherein the clamping rotary cutting machine is applicable to large-diameter wood, and the non-clamping rotary cutting machine is mainly used for small-diameter wood. As large diameter wood has been reduced in recent years, clampless rotary cutting machines have been used more widely.

The rotary cutting machine is used for processing wood sections with certain length and diameter into continuous veneer strips for producing plywood, fine wood upper plates and other artificial board veneers. The main technical parameters of the rotary cutter are the maximum length and diameter of the workable wood section, and the upper limit of the working is existed due to the vibration problem of the cutter.

Wherein the requirements of rotary cut veneers for electrical wood pressing are very strict; not only the electrician laminated wood is required to have good mechanical properties, but also the produced electrician laminated wood is required to have high insulativity, so that the requirements of high-grade transformers cannot be met;

because the existing rotary cutting machine used by electrical laminated wood has shorter length of processed wood, and the existing large-scale transformer uses longer wood pressing, short veneers produced by the existing rotary cutting machine are spliced, and then cut according to the use specification of the transformer; because the single board directly has splicing break points; the malposition of the wood holes is caused, so that the pressure-variable oil cannot smoothly flow, and the insulation performance of the electrical laminated wood is reduced; regarding the influence of the insulation of the electrical laminated wood on the transformer, please refer to journal "transformer" 2023, 7 months, 50 th period, application of the electrical laminated wood in the transformer and prospect analysis authors: li Caiyun, wang Wenchang, han Bin;

furthermore, after the veneers are spliced or lapped, the oil absorption rate of the laminated wood is reduced, and the existence of bubbles in the laminated wood in the process of soaking transformer oil is avoided, so that the risk of breakdown in the using process is reduced.
