Description

Automatic gluing device for veneer

Technical Field

The utility model belongs to a wood working machinery, specifically speaking especially relates to an automatic rubber coating device of veneer.

Background

Because the breadth of the veneer is narrow, when the veneer is processed into a wood board product with a larger area, the veneer needs to be spliced and bonded by using bonding glue to form a wood board with a larger size under the action of pressure. The concatenation of present veneer mainly has manual concatenation and splicer concatenation dual mode, manual concatenation adopts artifical manual less veneer of breadth to make its concatenation together through scribbling the adhesive at the kneck, the work efficiency of this production mode is extremely low, the splicer concatenation adopts automatic rubber coating device to scribble the adhesive at the veneer side, then solidification veneer under chill roll and cooling backing plate effect, present two kinds of concatenation mode veneer pieces together the interface and all adopts the straight line to piece together the interface, it is big with the volume of gluing, neither economic nor environmental protection, and seam crossing is cracked under the exogenic action very easily. The problem of splice joint disconnection can be solved to the concatenation mouth of zigzag, does not have a automatic rubber coating device to veneer sawtooth shape concatenation mouth rubber coating specially at present.

SUMMERY OF THE UTILITY MODEL

the utility model aims at providing an automatic rubber coating device of veneer to overcome and lack the defect of a rubber coating device of automatic to veneer sawtooth shape interface rubber coating among the prior art.

The utility model discloses an adopt following technical scheme to realize:

The automatic gluing device for the veneer comprises a glue storage box with an upper opening, wherein a first rotating shaft and a second rotating shaft which are arranged in parallel are arranged above the glue storage box, two ends of the first rotating shaft and two ends of the second rotating shaft are respectively connected with a shaft seat, a gluing tooth A and a gluing tooth B which are arranged at equal intervals are respectively fixedly arranged on the first rotating shaft and the second rotating shaft, and a rotary driving device is respectively connected to the first rotating shaft and the second rotating shaft.

Preferably, the adhesive teeth B and the adhesive teeth a are arranged in a staggered manner.

Preferably, the rotary driving device comprises an air cylinder, a rack and a gear, wherein an expansion rod of the air cylinder is fixedly connected with the rack, the gear is fixedly connected with the first rotating shaft or the second rotating shaft, and the rack is meshed with the gear.

compared with the prior art, the beneficial effects of the utility model are that:

The utility model discloses can realize simultaneously treating the apex of tooth or the tooth root of concatenation veneer sawtooth to two and glue, then join the sawtooth interface of two veneers together to reduced the volume of gluing of splice plate by a wide margin, both practiced thrift the cost, environmental protection safety again, the sawtooth structure can also increase the joint strength who splices the seam simultaneously.

FIG. 2 is a sectional view taken along line A-A of FIG. 1;

in the figure: 1. veneer of wood skin; 2. saw teeth; 3. a shaft seat; 4. a first rotating shaft; 5. adhesive teeth A; 6. a glue storage box; 7. a second rotating shaft; 8. adhesive teeth B; 9. a cylinder; 10. a rack; 11. a gear.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the automatic gluing device for veneer, including upper portion open-ended glue storage box 6, glue storage box 6 is inside to be used for holding the bonding glue, glue storage box 6 top is equipped with parallel arrangement's first pivot 4 and second pivot 7, first pivot 4 and second pivot 7 both ends are connected with axle bed 3 respectively, fix a plurality of glue teeth a5 and glue tooth B8 that are equipped with equidistant setting respectively on first pivot 4 and the second pivot 7, each glue tooth a5 and glue tooth B8 position correspond a prong or the tooth root of sawtooth 2 respectively, what glue tooth a5 and glue tooth B8 shown in fig. 1 correspond is the prong of sawtooth 2; the first rotating shaft 4 and the second rotating shaft 7 are respectively connected with a rotary driving device, the initial positions of the adhesive tooth A5 and the adhesive tooth B8 are vertically downward and immersed in the adhesive storage box 6, and when dispensing is needed, the rotary driving device can drive the first rotating shaft 4 and the second rotating shaft 7 to rotate 180 degrees.

Preferably, the viscose teeth a5 and the viscose teeth B8 are arranged in a staggered manner, because the saw teeth 2 of the two wood veneer sheets 1 to be bonded are complementarily inserted together, and the viscose teeth a5 and the viscose teeth B8 respectively correspond to the tooth tips or tooth roots of the saw teeth 2 of the two wood veneer sheets 1, after the glue is applied to the tooth tips or tooth roots of the saw teeth 2 of the two wood veneer sheets 1 respectively by the viscose teeth a5 and the viscose teeth B8, the next process can directly splice the two wood veneer sheets 1 to be bonded.

Preferably, the rotary driving device comprises a cylinder 9, a rack 10 and a gear 11, wherein an expansion rod of the cylinder 9 is fixedly connected with the rack 10, the gear 11 is fixedly connected with the first rotating shaft 4 or the second rotating shaft 7, and the rack 10 is meshed with the gear 11. When the telescopic rod of the air cylinder 9 acts, the rack 10 is driven to ascend or descend, the rack 10 drives the gear 11 to rotate, the gear 11 rotates to drive the first rotating shaft 4 or the second rotating shaft 7 to rotate, and the stroke of the air cylinder 9 just enables the viscose teeth A5 and the viscose teeth B8 to rotate 180 degrees along with the first rotating shaft 4 or the second rotating shaft 7.

The utility model discloses a working process: the tail end of the first veneer 1 and the front end of the second veneer 1 are respectively cut into saw teeth 2 through a saw tooth cutting machine, the saw teeth 2 of the two veneer 1 are just complementary, the two veneer 1 respectively and accurately reach the glue dispensing position under the driving of a conveying device, a cylinder 9 acts to drive a viscose tooth A5 and a viscose tooth B8 immersed in adhesive glue to turn over 180 degrees, the positions of the viscose tooth A5 and the viscose tooth B8 become vertical upward and respectively contact with the tooth tips or tooth roots of the saw teeth 2 of the corresponding veneer 1, so that the adhesive glue is dispensed on the tooth tips or tooth roots of the saw teeth 2, the cylinder 9 acts reversely after the glue is dispensed, and the viscose tooth A5 and the viscose tooth B8 recover the initial positions.
