Feed conveyor VK450

for firewoodrollerwith hydraulic adjustment

The centring infeed conveyor ensures a good grip of the log at the start of the debarking phase and an accurate control of log onto the debarker’s infeed line. VK infeed conveyors centre the logs both vertically and horizontally (X–Y centring) using a conveyor trough and a flap/roll, which places pressure on the log. The feeding of logs into the debarker is aided by the shape of the infeed conveyor’s flight chain – the flights push the logs forward. The infeed conveyor model VK450 was introduced onto the market in the early 1980s and several hundreds of these machines have already been delivered throughout the world. The model was specifically designed for small and medium-sized logs. The conveyor is available as standard equipment in the following machine models: VK26MX, VK26SMX, VK450 and Basic versions of the VK5000 series. VK infeed conveyors’ power transmission is handled using a worm gear. The conveyor’s drive sprocket is connected to the gear with a purpose-built cardan shaft. The power is transferred from the electric motor to the gear by V-belts. The pressure of the VK infeed conveyors is produced hydraulically. All VK infeed conveyors feature a pre-opening function of the flap. This function is required when debarking at a high feed speed or when feeding small or light logs in. In the VK450 conveyor model, a log’s approach is detected by photo cells at the start of the conveyor.
