Problems solved by technology

[0003] Due to the structural design defect of the traditional toner cartridge seal, it is difficult and inaccurate to locate during installation firstly; secondly, because the traditional toner cartridge seal has no sealing device, the toner cartridge is prone to powder leakage when the toner cartridge seal is pulled out and used, which affects the printing quality ; Again, there is no conductive aluminum sheet on the traditional toner cartridge seal and conductive contacts are on the printer. When using the laser printer, it is easy to report an error or because the position of the conductive aluminum sheet is not accurate. When using it, the installer needs to fold the conductive aluminum sheet backwards, resulting in There are many work steps during installation and the work efficiency is low

Embodiment

[0018] As we all know, the toner cartridge seal of laser printers plays a role of sealing and moisture-proof during the production of the toner cartridge, so that the toner in the toner bin does not leak out. figure 1 It is a structural schematic diagram of an embodiment of a laser printer toner cartridge seal of the present invention, as figure 1 As shown, it includes bottom plate 1, sealing strip 2 and drawstring 3, bottom plate 1 is made of polystyrene, bottom plate 1 and sealing strip 2 are provided with drawstring groove 4 suitable for drawstring 3, and drawstring 3 is in this After the embodiment is made, it is located in the drawstring groove 4. The bottom plate 1 and the sealing strip 2 are adhesive structures, and the draw tape 3 is bonded between the bottom plate 1 and the sealing strip 3. There is a positioning gap 5 on the bottom plate 1. The original toner cartridge seal has no positioning device, and it is difficult to locate during installation. , and the posit...

Abstract

The invention discloses a laser printer selenium drum sealing strip, which comprises a base plate, the sealing strip and a stretching strap, a stretching strap groove adaptable to the stretching strap are arranged on the base plate and the sealing strip, a bonding structure is provided between the base plate and the sealing strip, the stretching strap bonds between the base plate and the sealing strip, and a positioning gap is arranged on the base plate. The laser printer selenium drum sealing strip employed with the above structure, can accurately position while installing, can avoid powder leakage phenomenon generated by the selenium drum, and can simultaneously simplify the installation step for the installation operators.

Description

technical field [0001] The invention relates to a printer accessory, in particular to a laser printer drum seal. Background technique [0002] In order to facilitate the placement and transportation of the toner cartridge, and to prevent the print quality of the toner cartridge from being affected by damp toner, it is necessary to use a seal to seal the powder outlet of the toner cartridge compartment when producing the toner cartridge. Before using a new toner cartridge, the user needs to pull the seal strip by hand to open the powder outlet of the toner cartridge powder bin, so that the toner is in contact with the magnetic roller. [0003] Due to the structural design defect of the traditional toner cartridge seal, it is difficult and inaccurate to locate during installation firstly; secondly, because the traditional toner cartridge seal has no sealing device, the toner cartridge is prone to powder leakage when the toner cartridge seal is pulled out and used, which affect...
