This gas has only one benefit, which is to protect the earth and reduce the harm of solar radiation. Printers are one of the output devices of computers, and laser printers are common printers in life. Laser printers need to use toner to print information, so the mixing and feeding of toner is very important.

[0003] According to a mixing and feeding device for printer toner production disclosed in Chinese patent publication number CN 218840750 U, the device can separate the mixing, shorten the mixing time, and can feed the mixing and feeding device for printer toner production quickly. The utility model provides such a mixing and feeding device for printer toner production, including a mixing box, a discharge pipe and a feeding screw. The right side of the mixing box is symmetrically connected to the front and back and connected to the discharge pipe. The lower part of the mixing box is divided into two cavities. The feeding screw is rotatably arranged in the two cavities, and the feeding screw is located in the discharge pipe. The powder is poured into the mixing box and falls into the two cavities in the lower part of the mixing box, and then stirred evenly by the feeding screw. At the same time, the feeding screw can send the evenly mixed powder out through the discharge pipe, thereby achieving the purpose of shortening the mixing time and fast feeding.

[0004] However, when the device is in use, the powder needs to be manually poured into the barrel without protection, which easily generates dust and causes harm to the health of the workers, making the device have certain limitations. Utility Model Content

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model puts the extraction pipe into the interior of the storage bin, and then covers the storage bin with a dustproof cloth. The dustproof cloth is set to a loose shape to seal the storage bin, so that dust will not float around during extraction. Then, the feeding pump is started to drive the extraction pipe to extract the powder in the storage bin, and then the connecting pipe is connected to the feeding pipe to allow the powder to enter the feeding pipe. The weight is then detected by the weight detector at the bottom of the gravity plate. After the weight meets the standard, the feeding pump is turned off, and then the staff pulls the connecting column to make the connecting column slide in the blocking pipe until the blocking plate leaves the discharge port of the feed pipe. Then the powder is discharged and falls into the interior of the mixing barrel, so that there is no dust discharge during the entire feeding process, and the feeding operation is completed, thereby achieving the effect of protecting the safety of the staff.

[0016] Second, the utility model inputs the powder into the interior of the mixing drum through the feed pipe, and then starts the motor outside the crushing roller to drive the two crushing rollers to crush the powder to avoid powder agglomeration. The crushed powder then enters the interior of the mixing drum, and then starts the motor outside the stirring shaft to drive the spiral blades to stir and mix, and then is discharged from the discharge pipe at the bottom to complete the mixing and feeding operation.
