Description

Technical Field

[0001] The utility model relates to the field of copy equipment, in particular to a pipeline for recycling and conveying toner. Background Art

[0002] At present, application number 201920581708.9 discloses a fan for conveying printer toner. When in use, you only need to add materials to the inside of the material box, turn on the fan, and the fan will drive the extractor to work, draw the toner in through the guide tube, and then guide it into the designated position through the guide tube, so as to reduce the chance of contact between the staff and the toner and reduce the harm of the toner to the human body. The guide tube can be installed on the upper side of the discharge port by rotating the fixing sleeve. When the guide tube needs to be removed, just follow the above reverse operation, which is very convenient. The setting of the inclined plate can make the toner inside the material box automatically gather to the connection between the material box and the guide tube due to its own gravity, so as to facilitate the complete discharge of the material inside the material box. On the one hand, the spring coil can prevent the guide tube from bending. However, long-term bending will cause the guide tube to crack and cause toner leakage. On the other hand, the guide tube can be supported so that it is in an open state. The fan can drive the conical cover to extract the air on the upper side of the material box, so as to absorb the toner raised on the upper side of the material box and prevent the toner from flying around and being inhaled by the staff. When in use, it has the following shortcomings: part of the toner will adhere to the inner wall of the conveying pipe during transportation, so there will be some loss in transportation. At the same time, the toner will easily accumulate and agglomerate if it adheres to the inner wall of the pipe for a long time. After agglomeration, it will detach from the inner wall of the pipe and be transported again. The agglomerated toner will be mixed with the product toner, causing product quality problems. Therefore, a device is urgently needed to solve the above problems. Utility Model Content
