SU137663A1 - A method of making wood veneer - Google Patents

Description

The invention relates to a method for producing wood veneer using a shelling machine, a multi-story lamellar syringer and conveyors to move the tape and spike sheets.

A known method of making wood chips using a shelling machine is that the innona ribbon that comes out of the machine is cut into sheets and then dried in a dryer.

In the proposed method, for the purpose of threading, the P1pona tape is subjected to drying, then it is cut into sheets of a given size and, with the help of a conveyor, the sheets are distributed into sub-steps corresponding to certain types of veneer.

In addition, in the proposed method, in order to prevent spraying, the veneer tape in the upper section of the dryer is subjected to drying in the clamped state between the plate conveyors, and upon further transition from the floor to the floor, the veneer tape is released for its free drying.

The drawing shows a diagram of an apparatus for carrying out the proposed method. According to the proposed method, the tape of the spike, obtained from the block 1, separated on the machine 2, falls on the conveyor 3 and is placed on the non-loops 4. The conveyor 3 has a folding part 5 which allows the peeling of the veneer to direct the torn tape veneer 6 on the conveyor 7 cleaning.

The rotating rollers 8 press the ends of the veneer to the stop ruler 9, thus ensuring the right direction for the veneer when loading into the tavern.

The end of the veneer tape is tucked between the chains of the inclined conveyor 10, which loads the spike tape into the insert 11, consisting of eight to ten special conveyors 12; adjacent branches of the conveyors move into one. direction and transport sandwiched between conveyors shponpon.

No. 137663-2. The main difficulty in designing an assembly for drying veneer tapes is the need to prevent cracking and breaking of the veneer tapes during drying from shrinking wood, which is 6-8% of the size of raw veneer.

Studies have shown that the gap in the clamped state occurs after moisture is removed from the veneer by an amount that causes shrinkage above 0.8-0.9%. If the veneer is released at this point, then the tensile stresses are extinguished and the veneer does not break. In the proposed drying unit, the veneer is released at the time of transition to the adjacent floor. Thus, the number of floors of the dryer is determined from the conditions for ensuring the removal of moisture in each floor by an amount that ensures drying of not more than 0.8-0.9%. Research has shown that, if there are 8-9 floors in the dryer, it is possible to reliably prevent tearing (cracking) of the veneer tape during the drying process. The flaps 13 give direction to the veneer when moving from one dryer floor to another. The veneer is dried by flue gases.

The dried veneer tape is fed by an inclined conveyor 14 to the conveyor 15, where it is automatically cut into sheets of a given width using scissors 6. The sliced veneer sheets with the help of a special conveyor / 7 are distributed along podtopnymi places 18.

Subject invention

Claims (2)

1. A method of making wood veneer using a shelling machine, a multi-storey plate dryer and conveyors for moving tape and veneer sheets, characterized by 1 that, for the purpose of manufacturing, the veneer tape is dried, then it is cut into sheets of a given size and using conveyor sheets distributed to podstopnyh places corresponding to certain types of veneer. 2. Acceptance of the method according to claim 1, from l and h and with the fact that, in order to prevent cracking, the veneer tape in the upper floor of the dryer is dried in the clamped state between the plate conveyors, and upon further transition From floor to floor, the veneer tape is free to dry out.
