Description

Technical Field

[0001] The utility model specifically relates to the field of electronic processing, in particular to a feeding device for a baking tunnel furnace. Background Art

[0002] Tunnel oven is a tunnel-type mechanical equipment that bakes food through heat conduction, convection and radiation. The oven body is usually very long, with a minimum length of 6 meters and a maximum length of 60 to 80 meters. The baking chamber is a narrow tunnel with a width of 80 cm to 140 cm. There is a continuously operating conveying system in the tunnel. When the food is baked, the food moves relative to the electric heating element or direct-fired combustion rod through the conveying chain plate, steel belt or mesh belt, thereby completing the work of uniform baking and conveying. This type of oven can be produced continuously, with high production efficiency, labor saving and stable baking quality.

[0003] In the field of electronic processing, manual operation is often required when electronic products are loaded into a tunnel furnace for baking. On the one hand, the electronic products are easily touched during the loading process, causing contamination to the electronic products. On the other hand, the electronic products are placed at uneven intervals during loading, which affects the removal of the materials after baking.

[0004] Therefore, we propose a baking tunnel furnace feeding device to solve the above problems. Utility Model Content
