Description

Technical Field

[0001] This invention relates to the field of square timber splicing technology, and in particular to a square timber splicing device and method. Background Technology

[0002] Timber splicing, as the name suggests, involves manually (or semi-automatically) joining short, old timber pieces together to make them usable and efficient, while also saving construction companies significant costs. Many construction sites across the country now hire professional timber splicing teams to handle this process.

[0003] The main sources of these waste materials are large construction companies and construction sites. Each construction unit generates a large amount of short planks and timber during construction, which not only take up space but also pose fire safety hazards. Generally, companies treat this waste as garbage and pay for disposal. Some companies, however, organize personnel specifically to clean and organize these short timbers or lumber, or to splice them together. But due to high labor costs, improper operation, or poor splicing techniques, the organized and spliced ​​timber is often completely unusable. Summary of the Invention

The first hydraulic cylinder 15 pushes the clamping plate 14 to clamp and fix the square timber.

The second motor 118 drives the cutting roller 112 to cut the joint groove at the end of the square timber. The hydraulic cylinder retracts and pulls back the sliding platform 13.

[0045] S3: The second hydraulic cylinder 18 and the first hydraulic cylinder 15 retract in sequence, remove the square timber, dip the end of the square timber with the butt groove in the glue bucket 212 and place it in the limiting purlin group 22, and place the end without the butt groove against the push plate. Then take another square timber, dip it in glue, and then insert the butt grooves of the two square timbers together. The fourth hydraulic cylinder 25 pushes the pressure beam down to press on the square timber to fix the square timber.

[0046] S4: The third motor 217 drives the second cutting blade 215 to rotate, and the fifth hydraulic cylinder 214 pushes the rotating rod 216 to rotate, thereby extending the cutting blade from the cutting seam 211 to the upper surface of the second frame 21 to achieve the cutting of the square wood;

[0047] S5: Rotate the stop bar 29 onto the second frame 21. One end of the stop bar 29 is connected to the rotating table 28, and the other end is blocked by the stop block 210, so that the stop bar 29 supports the square wood. The third hydraulic cylinder 23 extends to push the push plate to squeeze the square wood, so that the square wood is firmly connected.

[0048] S6: The fourth hydraulic cylinder 25 and the third hydraulic cylinder 23 retract in sequence, lift the stop lever 29, and take out the spliced ​​square timber.

[0049] In step S5, after the pressure beam is pressed down, the limiting wing plate 26 is inserted into the limiting groove 27. When the third hydraulic cylinder 23 pushes the square timber, it prevents the pressure beam from being dragged and damaged by the friction force at the moving end of the fourth hydraulic cylinder 25.

Then take another square timber and dip it in glue. Then insert the butt grooves of the two square timbers together. The fourth hydraulic cylinder (25) pushes the pressure beam down to press on the square timber to fix the square timber. S4: The third motor (217) drives the second cutting blade (215) to rotate, and the fifth hydraulic cylinder (214) pushes the rotating rod (216) to rotate, thereby extending the cutting blade from the cutting seam (211) to the upper surface of the second frame (21) to achieve the cutting of the square wood; S5: Rotate the stop bar (29) onto the second frame (21). One end of the stop bar (29) is connected to the rotating table (28), and the other end is blocked by the stop block (210), so that the stop bar (29) supports the square wood. The third hydraulic cylinder (23) extends to push the push plate to squeeze the square wood, so that the square wood is firmly connected. S6: The fourth hydraulic cylinder (25) and the third hydraulic cylinder (23) retract in sequence, lift the stop lever (29), and take out the spliced ​​square timber.
