A powder drum drum unit

Technical field

Areas of the utility model relates to a printer, particularly relates to a powder drum drum unit.

Technical background

Existing technology in printers, cartridges and drum rack part combination, according to different types of printers and be fitted with different specifications of the powder compact, cause on the design and use of waste, cause resource waste, at the same time increased the complexity of the customers to use.

Utility model content

The utility model technical problems to be solved is to provide a drum, drum powder can be general all types, and reduce the dosage of single cartridges environmental protection materials, in order to solve in the multiple defects in the existing technology.

To achieve the above purpose, the utility model provides the following technical scheme: the integration of the selenium drum, a drum powder including cartridges and drum frame, compact and drum rack for one-piece structure, described with drum drum core and developing roller, transfer roller, drum core and developing roller, transfer roller driven by gear transmission component rotation, gear transmission components installed in the outside walls of the drum drum unit installation has a positive powder knife, the powder knife relative to the magnetic roller tangent, developing roller and transfer printing roller and drum core tangent respectively.

Optimization, described in the paper drum unit on bottom is equipped with auxiliary frame, selenium drum bottom corresponding auxiliary rack installation location is equipped with buckle on paper, paper card in the bottom of the drum unit auxiliary frame and side button bits.

Optimization, drum unit described in the drum core and developing roller, transfer roller at both ends is equipped with spring and tension spring.

Optimization, drum unit described in the drum core and developing roller, transfer roller ends with pollution TAB.

Adopting the above technical scheme of beneficial effect is that the utility model of the structure of the powder of drum drum, drum rack compact body structure, greatly improve the stability of the products in the printing process and increase the print service life, and implements the drum powder products can be integrated in general use, and reduce the dosage of single cartridges environmental protection materials.      The appended drawings show

Figure 1 is the utility model structure schematic drawing of the front;

Figure 2 is the utility model base structure schematic diagram;

Figure 3 is on one side of this practical new type of structure schematic diagram;

Figure 4 is on the other side of the structure diagram of this practical new type;

Figure 5 is the new utility model transfer printing roller of the structure diagram.

Among them, 1 — drum unit, 2 – gear transmission components, 3 – powder knife, 4 -, 5 – transfer printing roller, drum core 6 – developing roller, 7 – on paper and auxiliary rack, 8 – spring, 9 – tension spring, 10 – pollution TAB.

Concrete implementation way

Combined with the appended drawings below detailed optimization of this utility model implementation ways.

Figure 1, figure 2, figure 3, figure 4 and figure 5 show the specific implementation of the utility model: a powder drum drum unit 1, including cartridges and drum frame, compact and drum rack for one-piece structure, described with drum core 4 and developing roller drum unit 1 6, 4 and imaging drum core roller turn 6 driven by gear transmission component 2, gear drive component 2 set in the outside walls of the drum unit 1 drum unit 1 positive installation powder knife is 3, the powder knife three relative to the magnetic roller six tangent, developing 5 6 and transfer printing roller and drum core 4 tangent respectively.

7 auxiliary drum bottom is equipped with the paper, paper drum unit 1 on the underside of corresponding auxiliary frame 7 installation location is equipped with buckle, paper and auxiliary frame within 7 card button is a;

Drum unit 1 in 4 and drum core development on both ends of the roller is equipped with spring 8 and 9; tension spring

Drum unit 1 in 4 and in the drum core development on both ends of the roller is equipped with pollution TAB 10.

Cartridges cartridges in drum rack, namely, integrates drum powder;

Install all components of the gear set design in powder on the integration of the selenium drum, drum to prevent the occurrence of beating, printed in the powder drum drum drive gear to realize integrated a can full of general drive gear;

Compact powder the knife from the side before installation, the series of drum powder of the blade design is installed on the drum unit from the front, to improve the powder knife control uniformity and printing blackness;

Add the paper auxiliary drum bottom frame, the parts will stick to button at the bottom, the drum level, mainly used for the auxiliary fixing on printing paper from the bottom of the drum unit components and drum core components, not achieve card fault;

Drum unit on both ends of the drum core increase spring tension spring and realize the carbon powder is on the enhancement of roll core adsorption exposure to print out text, and eliminate the print of the beating;

Inside the drum unit of drum core, developing roller, transfer roller increases the ends of the pre-sale quarantine pollution pollution TAB, promote customer can get stable printing effect before use.

The utility model of the structure of the powder of drum drum, drum rack compact body structure, greatly improve the stability of the products in the printing process and increase the print service life, and implements the drum powder products can be integrated in general use, and reduce the dosage of single cartridges environmental protection materials.

Of the above is only the utility model optimization implementation methods, it should be pointed out that for the ordinary technical personnel in the field of without from under the premise of the utility model creation idea, still can make a number of deformation and improve, these are part of the scope of protection of the utility model.
