Sealing method for carbon powder box

Abstract

The invention relates to sealing method of carbon powder box, the carbon powder box includes a power storehouse housing the carbon powder; the power storehouse possesses a meal outlet which can be sealed by sealing strip, the surface of meal outlet and the surface of tearing band export located at the side of the meal outlet are intersected. The seal element possesses adhesive layer and the first stripping layer and the second stripping layer which is located at the side of the adhesive layer, a opening which is basically anastomotic with the meal outlet is set at middle of the adhesive layer, the first tearing band and the second tearing band are separately extended from the zigzag ends of the first stripping layer and the second stripping layer. The methods contain: the zigzag ends of the seal element is inserted into the top of the meal outlet from the tearing band export; the first stripping layer is extracted from the tearing band export by the first tearing band which is near the surface of meal outlet and inlet, all-around of the adhesive layer and meal outlet is bonded seal. The process of resealing is simplified, the cost is saved, and the damage of carbon powder box resolution in current technique is also avoided.

Description

technical field [0001] The invention relates to a method for sealing a carbon powder box. Background technique [0002] Printers and copiers are commonly used office equipment. Existing laser printers or copiers generally have replaceable toner cartridges. Considering factors such as cost reduction and environmental protection, it is very important to recycle used toner cartridges. Necessary, and practice has proven to be feasible. During the recycling process of the toner cartridge, it is not only necessary to refill the toner cartridge with toner, but also to seal the toner outlet of the toner cartridge to prevent leakage of the toner during packaging and transportation. If the user needs to insert the toner cartridge into the printer or copier for work, an appropriate method must be used to open the sealing structure of the toner cartridge, so that the toner can flow out from the powder outlet smoothly, so that the laser printer or copier can Subsequent printing or copy...

AI Technical Summary

Problems solved by technology

However, this sealing method must first separate the powder bin of the toner cartridge from the toner cartridge, paste one side of the sealing strip to cover the powder outlet of the powder bin, and then use welding or other methods to reconnect the powder bin to the on the toner cartridge

Since the process of separating the powder bin requires the use of cutting equipment, the process is relatively complicated, and it is easy to cause irreparable damage to the toner cartridge. On the other hand, re-welding the powder bin to the toner cartridge requires corresponding welding equipment and process. It is also very complicated, and the high-heat welding torch can easily damage the plastic toner cartridge
