The Auto Feeding Machine is a machine designed for suction and conveyance of plastic granules. It can automatically suck up plastic granules and transport them through plastic pipes to the hopper of an injection molding machine or a dryer. This device frees up manpower, facilitates material filling, and eliminates the need to climb onto the machine for feeding. Auto Feeding Machine meets the requirements of automated production and enhances production efficiency. Made of wear-resistant engineering plastic and corrosion-resistant stainless steel, its suction nozzle and conveying pipes are anti-clogging and durable. Equipped with a high-power vacuum pump, it ensures stable suction force and fast conveying speed, with adjustable conveying capacity to match different production needs. It has an automatic material shortage alarm function and a dust-proof design, avoiding material waste and workshop pollution, and its compact structure saves space, easily integrating with other plastic production equipment.
