[0032] Please refer to Figure 1 、 Figure 2 As shown, a production system for a composite veneer panel is provided, including a conveyor 6, a sizing device 5 for spraying formaldehyde-free glue, and a continuous press 7. The conveyor 6 can be a belt conveyor 6. The sizing device 5 mainly includes a nozzle and a supply mechanism connected to the nozzle for supplying formaldehyde-free glue (MDI glue). The continuous press 7 uses its upper hot plate and lower hot plate to thermally press and laminate the veneer panel. Along the conveying direction of the conveyor 6, a first surface veneer placement area, a core veneer placement area, and a second surface veneer placement area are provided on the conveyor 6. Sizing devices 5 are provided between the first surface veneer placement area and the core veneer placement area, and between the core veneer placement area and the second surface veneer placement area. The sizing device 5 between the first surface veneer placement area and the core veneer placement area is arranged close to the core veneer placement area, and the sizing device 5 between the core veneer placement area and the second surface veneer placement area is arranged close to the second surface veneer placement area. The sizing device 5 is arranged close to the core veneer placement area or the second surface veneer placement area, which can shorten the time from the completion of glue spraying to the next veneer placement area, preventing the formaldehyde-free glue from curing. The continuous press 7 is arranged on the conveying path of the conveyor 6, and the continuous press 7 is located behind the second surface veneer placement area. In this system, the conveyor 6 can automatically complete the conveying of the veneer panels, with high overall automation, capable of realizing the continuous production of the composite veneer panel, thereby improving production efficiency, effectively improving the blanking efficiency of the composite veneer panel, and shortening the matching interval time between different veneer panels. With the shortening of the matching interval time, formaldehyde-free glue can be used between the veneer panels, improving the quality of the composite veneer panel and ensuring that the produced composite veneer panel has good environmental protection effects.

[0033] In this embodiment, the sizing device 5 includes a plurality of nozzles, and the plurality of nozzles are arranged in a row along the width direction of the conveyor 6.

[0039] Since water or additives may be needed between the layers of the composite veneer board, the system also includes a liquid spraying device 4 for spraying water or additives, wherein water is a curing agent and the additives are flame retardants and other additives that need to be added additionally. The liquid spraying device 4 is arranged between the first surface board placement area and the core layer board placement area and between the core layer board placement area and the second surface board placement area. The liquid spraying device 4 is arranged in front of the glue applying device 5. The arrangement of the liquid spraying device 4 further improves the degree of automation of the system.

[0040] The liquid spraying device 4 comprises a spray head and a supply mechanism for supplying water or additives to the spray head.

[0041] In this embodiment, the robot 2 is provided with a plurality of vacuum suction cups for sucking the layer boards. Compared with the clamping method using claws, the layer boards are transported by vacuum suction, which can effectively reduce the damage to the layer boards.
