Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Fig. 1 is a kind of structural representation being provided with the toner cartridge embodiment of powder layer thickness control device described in the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in fig. 1:
The toner cartridge of powder layer thickness control device is provided with described in the utility model embodiment, include housing 1, be provided with powder storehouse 2 and developer roll 3 in described housing 1, described developer roll 3 is located at the meal outlet place in powder storehouse 2, and contacts with the powder outlet cutter 4 that meal outlet inner top side is provided with and connect.Be provided with powder layer thickness control device in described powder storehouse 2, described powder layer thickness control device comprises nonmagnetic elastomeric isolation sheet 5 and puddle support 6; Described elastomeric isolation sheet 5 to be longitudinally located in powder storehouse 2 and near meal outlet, the interior side body in its upper end and powder storehouse 2 is connected and fixed, lower end extends to the side of powder outlet cutter 4 and the contact junction on developer roll 3 surface and parallel with developer roll 3, forms isolation cavity 7 above powder outlet cutter 4; Described puddle support 6 is located in powder storehouse 2 rotationally, and clashes into the lower end of elastomeric isolation sheet 5 and be connected, and the lower end of elastomeric isolation sheet 5 can be swung left with automatically reseting.
Wherein, described elastomeric isolation sheet 5 can be plastic resilient sheet or metallic elastic sheet, its lower end rim is provided with cylindrical rim 51, described cylindrical rim 51 with elastomeric isolation sheet 5 one-body molded and with developer roll 3 keeping parallelism, and cylindrical rim 51 is straight through being greater than the thickness of elastomeric isolation sheet 5.Described puddle support 6 comprises mixing arm 61 and elastic dialing moving plate 62, and one end of described mixing arm 61 is located in powder storehouse 2 rotationally, and the other end is provided with described elastic dialing moving plate 62.And described puddle support 6 is positioned at the right side of elastomeric isolation sheet 5 lower end, and the extended line of the connection of its rotation axis and elastomeric isolation sheet 5 lower end rim (cylindrical rim 51) is positioned at the below of the contact junction on powder outlet cutter 4 and developer roll 3 surface.
When toner cartridge described in the utility model uses, elastomeric isolation sheet 5 effectively prevents carbon dust from entering isolation cavity 7, piles up, is pressed on powder outlet cutter 4; And when mixing arm 61 turns to ad-hoc location (namely facing to the cylindrical rim 51 in lower end of elastomeric isolation sheet 5), described elastic dialing moving plate 62 clashes into the lower end (cylindrical rim 51) of elastomeric isolation sheet 5 and is connected, the lower end of elastomeric isolation sheet 5 is swung left, reduce the distance between the lower end (cylindrical rim 51) of elastomeric isolation sheet 5 and developer roll 3, control carbon dust in powder storehouse 2 and carry out the powder amount of the contact junction on powder outlet cutter 4 and developer roll 3 surface; Then the lower end of spacer 5 automatically resets, distance between the lower end (cylindrical rim 51) of elastomeric isolation sheet 5 and developer roll 3 becomes large, enter powder outlet cutter 4 can automatically drop out with the carbon dust of the contact junction on developer roll 3 surface, continue Homogeneous phase mixing under the effect of mixing arm 61 with carbon dust in powder storehouse 2; Circulation like this repeatedly, directly only prints end.
Like this, the utility model toner cartridge can avoid carbon dust to pile up by powder layer thickness control device, be pressed on powder outlet cutter 4, significantly reduce powder outlet cutter 4 born burdens, thoroughly solve traditional toner cartridge due to powder outlet cutter accumulated powder too much, bear excessive thus cause the diastrophic defect problem of powder outlet cutter, powder outlet cutter 4 pairs of developer roll 3 adsorption carbon dust THICKNESS CONTROL are more accurate, evenly, imaging results is better, more stable, more reliable, long service life, toner cartridge print quality is better, and structure is simple, production and processing is easy, cost is low, the market competitiveness is strong, be easy to promote, sell, thus acquisition business success.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
