Abstract

The utility model discloses a veneer dryer comprising an oven, of which one end is provided with a charging inlet and the other end is provided with a discharging outlet. Moisture discharging pipes are arranged on the top of the oven, and a plurality of roller groups are horizontally arranged in the oven. Each roller group comprises an upper roller and a lower roller correspondingly arranged, wherein the lower roller is an active roller driven by a power device. Heat dispersion devices are respectively arranged above and under the plurality of roller groups. The veneer dryer has the advantages of being uniform in heating veneers, high in heating efficiency and rapid in heating speed. When a veneer is clamped by roller groups and moves forward, the peeled veneer clamped and pressed by the upper rollers and the lower rollers becomes flat and smooth. In this way, dried veneers are uniform and identical in quality. Compared with conventional drying means, the veneer dryer is higher in production efficiency.

Description

The wood single-plate dryer

Technical field

The utility model relates to wood single-plate drying plant technical field, specifically, relates to a kind of wood single-plate dryer.

Background technology

Wood single-plate is musculus cutaneus, wooden skin again, and its main application is to be used for producing artificial boards such as glued board, core-board, template, thick china.Wood single-plate divides two kinds of rotary-cut and slicings, and mostly the veneer that wood-based plate uses is rotary-cut.The wood single-plate that goes out because of rotary-cut contains large quantity of moisture, just can be used for producing artificial board after the processing so need dry it.

Traditional drying mode is that more than airings of wood single-plate that rotary-cut is gone out are under sunshine; Make wood single-plate become dry through water evaporates; But the defective that this airing mode exists is to take a large amount of places, and production efficiency is low, the easy turnup distortion of the wood single-plate after the airing; Difficult quality guarantee, but also to receive the restriction of weather conditions.

Also there is a lot of wood single-plate manufacturer to adopt drying plant that wood single-plate is dried processing now; Its used drying plant is an earth kiln, and is promptly roasting with fire, though also can dry musculus cutaneus in this way; But the wood single-plate water content after the baking is very inhomogeneous, and quality still is difficult to guarantee.

The utility model content

The utility model technical problem to be solved is: to above-mentioned defective a kind of wood single-plate dryer is provided, so that wood single-plate is heated evenly, and dried timber veneer good planeness, quality uniformity.

For solving the problems of the technologies described above, the technical scheme of the utility model is: the wood single-plate dryer comprises baking oven; One end of said baking oven is provided with charging aperture; The other end is provided with discharging opening, and the top of said baking oven is provided with damp air discharge pipe, has been horizontally disposed with a plurality of roller groups in the said baking oven; Each roller group comprises a corresponding upper roller and lower roller that is provided with, and said lower roller is the active roll tube that is driven by power set; The above and below of said a plurality of roller groups is respectively arranged with heat abstractor.

As optimized technical scheme, said power set comprise motor, and the chain and sprocket driving device that is connected with the output of said motor; Said chain and sprocket driving device comprise the sprocket wheel that is installed in each lower roller axle head and with the chain of said sprocket engagement.

As optimized technical scheme; The both sides of said each roller group are respectively arranged with and prevent the roller bearing block seat of roller to two side shiftings; Said roller bearing block seat comprises base plate; With two risers that are provided with perpendicular to said base plate, on the relative face of said two risers respectively correspondence be provided with vertical groove; The axle head of said each upper roller, lower roller is separately installed with bearing, and said bearing is positioned at said vertical groove, and said each upper roller can fluctuate along said vertical groove through the bearing of its axle head.

As optimized technical scheme, also be provided with the heat conduction blower fan in the said baking oven.

As optimized technical scheme, said heat abstractor is a heat conducting oil pipe.

As optimized technical scheme, described wood single-plate dryer comprises that also the charging aperture of the smooth case of said cooling is communicated with the discharging opening of baking oven near the smooth case of cooling of the discharge end setting of baking oven, and the top of the smooth case of said cooling is provided with blast pipe.

Owing to adopted technique scheme, the beneficial effect of the utility model is: the wood single-plate dryer of the utility model in use, wood single-plate is sent into by the charging aperture of baking oven; The roller group clamping of being made up of upper roller and lower roller afterwards moves ahead; In the process that moves ahead, wood single-plate is heated drying from upper and lower faces, wood single-plate is heated evenly by the heat abstractor that is positioned at roller group above and below; Receive that heating rate is high, drying speed is fast; Roller group clamping wood single-plate moves ahead in the process, and the wood single-plate that rotary-cut goes out becomes smooth smooth, the wood single-plate quality uniformity behind the drying because of clamping and the extruding that receives upper roller and lower roller; Compare with traditional drying mode, use the wood single-plate dryer of the utility model to enhance productivity greatly.

Because the both sides of each roller group are respectively arranged with and prevent that the roller bearing block seat of roller to two side shiftings, roller bearing block seat from comprising base plate and two perpendicular risers, on the relative face of two risers respectively correspondence be provided with vertical groove; Thereby the bearing of each upper roller axle head can fluctuate along said vertical groove and drive upper roller and fluctuate, with the production needs of the wood single-plate that adapts to different-thickness.
