Abstract

The utility model belongs to a processing apparatus of an artificial plate, which can be used for the production field of a bamboo wood adhesive bonded panels and veneer decorative materials. The utility model is composed of a pair of or a plurality of pairs of parallel rollers, wherein, the mutual gap of the parallel roller can be adjusted; a bearing seat of an upper roller is fixed; teeth are arranged on the upper roller; a tooth cross section is a triangular; a lower roller is a flat roller; the bearing seat can be moved in a slide groove. When a bamboo tube which is split, removed with sections and softened horizontally passes through between two rollers, roller teeth of the upper roller can apply vertical pressing force for an inner wall of the bamboo tube. Thereby, the bamboo tube can generate horizontal force to force the bamboo tube to expanse. Meanwhile, the roller teeth can prevent fine crank extension.

Description

The Bamboo flattening device

The utility model belongs to the wood-based plate process equipment, can be used for bamboo plywood and face decoration material production field.

The bamboo growth is fast, and the cycle is short, is the good material that substitutes timber.The flattening of bamboo is the key technology during bamboo plywood and decorative panel are produced.CN2044541, CN1120484 relate to the equipment that bamboo flattens.Because these two kinds of equipment are in service, bamboo all is an axial feed, passes through to launch gradually.The bamboo wood internal stress is very big, and wall thickness, diameter, the glacing flatness of adding a bamboo different parts change greatly, are difficult to avoid not cracking.There is the bamboo wood of crackle in bamboo plywood, still can use, but just greatly reduces as the value of finishing material.

The purpose of this utility model provides a kind ofly can produce tens centimeters long, and tens centimeters wide, the flattening device of flawless bamboo chip.To satisfy the needs that bamboo wood decorative panel and bamboo wood finishing material are produced.

The technical solution of the utility model is, a bamboo is vertically gone up the application of force simultaneously, allows the roller tooth at the vertical extrusion fiber of thick bamboo tube inwall, produces cross force, forces thick bamboo tube to launch, and the roller tooth can stop the blind crack expansion simultaneously.

Concrete device is as follows:

Accompanying drawing is a schematic diagram of device.A pair of or several to roller parallel to each other, last roll bearing seat is fixed on the frame, and last roller strap tooth, tooth section are triangle, tooth pitch 3～5mm, tooth depth 3～5mm.Lower roll is a plain-barreled roll, and bearing block can be regulated its gap and pressure with top roll by hydraulic pressure or mechanical force in chute, and this adjusting should be flexibly, conveniently.Look the size of bamboo and the size of wall thickness and product.The diameter of roller can be 40～150mm, length 300～1000mm, roller linear velocity 0.05～0.1m/ second.Should notice that especially the thick bamboo tube that launches is long more, the thick bamboo tube vary in diameter can be big more, easy more cracking.Should shorten the thick bamboo tube of expansion satisfying under the product requirement as far as possible.

When this device uses, thick bamboo tube is removed joint, cut thermoplastic open after, inwall is laterally sent between two rollers discaling roll, bamboo promptly flattens after the extruding of two rollers, it is too little to note regulating two roller gaps, thick bamboo tube easily bends towards reverse side, and is too big, then once can not launch fully.

This apparatus structure is simple, the efficient height, and quality is good, does not need cooling and shaping after the flattening.The bamboo softening degree has considerable influence to quality, and mao bamboon need be handled 1 hour in the time of 120 ℃, footpath in the cizu etc., and thin-walled bamboo number minute gets final product.

Claims

1, a kind of Bamboo flattening device is characterized in that adopting the thick bamboo tube wall pressurization of roller to traverse feed.Part changes the thick bamboo tube interior wall construction and with Bamboo flattening.Device is made up of a pair of or several rollers that axis is parallel to each other.Last roll bearing seat and frame are fixed.Bottom roll bearing block is regulated gap and the pressure of lower roll to top roll with this in chute.

2, Bamboo flattening device according to claim 1 is characterized in that top roll is a discaling roll, and the tooth section is a triangle, tooth pitch 3～5mm, and tooth depth 3～5mm, lower roll are plain-barreled roll.
