[0004] However, in the prior art, the thick veneer raw materials of veneer laminates need to be stacked after the gluing operation, and the thick veneer joints are connected to each other in a staggered overlap manner during stacking. Hollowing may occur at the staggered positions. After the stacked thick veneers are extruded and formed by a rolling device, since the wood has a certain elasticity, the hollowing at the staggered positions of the veneer laminates after forming will not be dented due to extrusion. The appearance quality of the formed veneer laminates is qualified, but the strength of the veneer laminates at the overlap positions with hollowing will become low, resulting in quality defects. The existing rolling equipment does not have a rolling pressure value monitoring structure, and the overlap positions cannot be fully inspected during the production process. The strength of the veneer laminates after production is inspected by random sampling, and the joints between the thick veneer raw materials cannot be fully inspected, which may cause some veneer laminates with quality defects to flow into the market.

[0042] One end of the driven bevel gear 114 is fixedly connected to a transmission shaft 115, which is rotatably connected to the reinforcement frame 112, and the reinforcement frame 112 is fixedly connected to the fixed platform 11. The upper part of the fixed platform 11 is fixedly connected to a guide frame 110, and one side of the guide frame 110 is fixedly connected to a connecting box 111, which is rotatably connected to the transmission shaft 115.

[0046] When producing veneer laminated lumber, when the hydraulic cylinder 26 pushes the No. 1 fixing plate 27 to move downward, it will drive the fixing frame 31 to move downward. When the fixing frame 31 moves downward, it will push the brush plate 39 to the surface of the veneer laminated lumber. When the No. 3 connecting plate 32 moves downward to push the brush plate 39 to the surface of the veneer laminated lumber, the No. 2 spring 34 and the telescopic rod 33 will be compressed and deformed. Under the reaction force of the No. 2 spring 34 and the telescopic rod 33, the brush plate 39 is pushed to the veneer laminated lumber. The materials are tightly fitted. During the production and transportation of the veneer laminated timber, the brush plate 39 will clean the wood chips and dust on the surface of the veneer laminated timber to ensure that the surface of the produced veneer laminated timber is clean. The plug plate 37 is connected to the mounting plate 35 to facilitate the replacement of the brush plate 39. When the brush plate 39 is fitted with the veneer laminated timber, the third limiting rod 36 will move along the third connecting plate 32 to limit the position of the brush plate 39, thereby improving the stability of the brush plate 39 during operation.

[0047] The method of use and working principle of this device are as follows: before the production and processing of veneer laminated lumber, the No. 2 connecting pipe 220 is connected to the control device of the external cylinder 216, and the thick veneer raw material coated with glue is passed from the upper part of the feeding roller 13 on the side of the No. 1 connecting frame 12. At this time, the hydraulic cylinder 26 is extended to push the No. 1 fixed plate 27 to move downward, thereby pushing the squeezing roller 210 to extrude the thick veneer raw material. During the downward movement of the No. 1 fixed plate 27, the No. 2 slider 24 pushes the No. 1 spring 214 and the No. 1 slider 23 to move downward. When the squeezing roller 210 squeezes the thick veneer raw material, the No. 1 spring 214 will be compressed, and at the same time, the pressure sensor 211 will monitor the pressure of the thick veneer raw material during processing;

[0048] Then the reduction motor 14 is turned on to drive the feeding roller 13 to rotate and feed the thick veneer raw material, and the squeezing roller 210 performs the rolling operation. In the process of rolling the thick veneer raw material, when hollowing occurs at the staggered overlap of the thick veneer raw material, when rolling the thick veneer raw material, when the hollowing position reaches between the feeding roller 13 and the squeezing roller 210, since the compressive strength of the hollowing position will become lower, the squeezing roller 210 will move downward at the hollowing position under the push of the No. 1 spring 214, and the pressure of the No. 1 fixed plate 27 on the No. 2 fixed plate 28 will change instantly, and the monitoring pressure value of the pressure sensor 211 will change instantly. The controller 212 will receive the data monitored by the pressure sensor 211. When the data monitored by the pressure sensor 211 changes instantly, it indicates that hollowing occurs at the staggered overlap of the thick veneer raw material. At this time, the controller 212 controls the solenoid valve 218 to open, so that the cylinder 216 is extended and the steel stamp 217 is inferred to mark the hollowing position.

[0049] When the thick veneer material is fed, the limit plate 17 is pushed to move by rotating the adjusting threaded rod 16 according to the width of the thick veneer material, and the distance between the limit plate 17 and the push plate 119 can be adjusted. When the limit plate 17 is moved, the No. 1 limit rod 18 is limited along the No. 1 connecting plate 15 to improve the stability of the limit plate 17 when it moves. The position of the limit plate 17 is adjusted to one side of the thick veneer material and fits with its side. When the feeding roller 13 rotates, it will drive the active The bevel gear 113 rotates, and under the action of the rotation of the active bevel gear 113, the driven bevel gear 114 and the transmission shaft 115 are driven to rotate, thereby driving the camshaft 116 to rotate, and at this time, the connecting shaft 117 is driven to push the push rod 118 to perform a reciprocating motion along the guide frame 110. Under the reciprocating pushing action of the push rod 118, the other side of the thick veneer raw material is pushed and sorted, so that both sides of the thick veneer raw material are kept neat, and the push plate 119 is directly driven by the feed roller 13 to sort the thick veneer raw material;

[0050] At the same time, when single board laminated timber is produced, when the hydraulic cylinder 26 pushes the No. 1 fixed plate 27 to move downward, it will drive the fixed frame 31 to move downward. When the fixed frame 31 moves downward, it will push the brush plate 39 to the surface of the single board laminated timber. When the No. 3 connecting plate 32 moves downward to push the brush plate 39 to the surface of the single board laminated timber, the No. 2 spring 34 and the telescopic rod 33 will be compressed and deformed. Under the reaction force of the No. 2 spring 34 and the telescopic rod 33, the brush plate 39 is pushed to fit tightly with the single board laminated timber. During the production and transportation of the single board laminated timber, the brush plate 39 will clean the wood chips and dust on the surface of the single board laminated timber.
