Multi-channel type automatic dispensing device

The utility model discloses a multi-channel type automatic dispensing device, which relates to the technical field of automatic dispensing devices, comprises two groups of support frames, a driving assembly, an adjusting mechanism and a limiting mechanism, and solves the problem that when a worker adjusts the glue discharge amount of the device by replacing a dispensing needle tube, the glue discharge amount is not changed, and the glue discharge amount is not changed. In order to solve the problem that the hand of a worker is in contact with a needle tube repeatedly and is scratched due to the fact that a nut needs to be installed and detached repeatedly, an adjusting mechanism is arranged, and when the glue outlet amount of a needle head needs to be adjusted, a pressing plate is moved downwards to drive a butt joint block to move; the butt joint hole in the butt joint block is gradually staggered with the glue injection hole and the pipeline in the needle tube, and the circulation space between the pipeline
