Description

Feeding and dust collecting device of extruder Technical Field The utility model relates to the technical field of feed inlet dust collection, in particular to a feeding dust collection device of an extruder. Background When the granular materials are fed by tilting the tail end of the pipeline, a large amount of dust can be raised, so that the loss of the materials is caused, the operation environment is polluted, and the health of operators is threatened. The utility model provides a dust fall feeding technical scheme of extruder feeding dustproof mechanism in the chinese patent of grant bulletin number CN220973269U, it mainly includes extrusion equipment and setting element, has the feeder hopper with the unloading on the extrusion equipment, is equipped with the fixed plate on the feeder hopper, is equipped with the blowing section of thick bamboo on the fixed plate, and the blowing section of thick bamboo tip articulates there is the apron, and the setting element is located on the blowing section of thick bamboo for fix the material bag tip and make it hoist, the blowing section of thick bamboo is installed on the fixed plate. However, the above structure has the following problems in daily maintenance and use: Blowing section of thick bamboo and feeder hopper fixed connection, though can reduce the raise dust through the confined space when reinforced, nevertheless when need clean, overhaul or dredge the inside of extruder feeder hopper, need whole dismantlement blowing section of thick bamboo and relevant subassembly, complex operation and consuming time.
