Description

Technical Field

[0001] This utility model relates to an automatic veneer discharge device for a veneer dryer, which is mainly used to reverse the output of dried veneer sheets. Background Technology

[0002] Before being processed into engineered wood panels, wood-based panels need to be dried. To improve production efficiency, existing panel dryers typically have multiple drying layers for drying individual panels. Each drying layer can have several panels spaced horizontally, thus increasing drying speed and efficiency. Therefore, after drying, an automatic panel discharge device capable of multi-layer discharge is required to smoothly output the dried panels. To maximize space utilization, the discharge end is often located on the side of the panel dryer; therefore, most existing automatic panel discharge devices have a reversing function.

[0003] Existing automatic plate-discharging devices with reversing functions generally include several rows of guide rollers arranged side-by-side on a frame at varying heights. A belt conveyor mechanism is positioned between these rollers to redirect the material output. This belt conveyor is driven by a corresponding lifting mechanism. During material output, the belt conveyor descends to the bottom of the guide rollers under the lifting mechanism, and the plates from the plate dryer are conveyed to the upper part of the belt conveyor. Then, driven by the lifting mechanism, the belt conveyor ascends to the top of the guide rollers to lift the plates. Finally, the belt conveyor activates to redirect the plate output. To ensure that the lifting process of the belt conveyor does not interfere with each other, existing belt conveyors are generally located inside the frame and driven by a mechanism located in the middle of the frame. This results in a large gap between adjacent rows of guide rollers, leading to a large spacing between multiple layers of plates within the plate dryer, which is quite cumbersome.

[0004] Therefore, the research objective of this utility model is to design an automatic veneer discharge device for a veneer dryer that can effectively reduce the gap between two adjacent rows of guide rollers and thus effectively reduce space occupation without causing interference.
