Description
Technical field
The utility model relates to a kind of handle box.
Background technology
In the electrophotographic imaging forming apparatus such as laser printer; The laser beam flying photosensitive drums of sending through laser instrument also forms electrostatic latent image on photosensitive drums; Utilize the carbon dust that stores in it that electrostatic latent image is become visible carbon dust image by handle box, then the carbon dust image is transferred on the print media through transfer device.In this process, photosensitive drums is to form electrostatic potential through charging device (like charging roller) on its surface, thereby the current potential that is lower than without exposure position by the current potential of the photosensitive drum surface of laser beam lithography position forms electrostatic latent image.Forward on the electrostatic latent image through the development bias voltage attached to the carbon powder particle on the developer roll, thereby form visible carbon dust image.
Fig. 1 is the diagrammatic cross-section of the handle box that prior art adopted, and knows that by figure handle box 100 comprises: developing frame 10 and cleaning framework 20, and developing frame 10 is injection mo(u)lding with cleaning framework 20; Developing frame 10 comprises the powder storehouse 14 that stores carbon dust T1, developer roll 11, carbon dust T1 is delivered to developer roll 11 lip-deep powder feeding roller 12 and regulates the powder delivery cutter 13 of carbon dust layer thickness on the developer roll 11; Developer roll 11, powder feeding roller 12 and powder delivery cutter 13 all are removably mounted on the developing frame 10; Powder delivery cutter 13 comprises powder delivery cutter blade 13a and powder delivery cutter fixed mount 13b; As shown in Figure 5, powder delivery cutter 13 is through powder delivery cutter fixed mount 13b and developing frame 10 fixed installations; Cleaning framework 20 comprises that waste powder hopper 24, the photosensitive drums 21 of the useless powder T2 that storage is got off from photosensitive drums 21 cleaning surfaces, the charging roller 22 of giving photosensitive drums 21 chargings and cleaning remain in the cleaning doctors 23 that carbon dust is gone up on photosensitive drums 21 surfaces after transfer printing; Photosensitive drums 21, charging roller 22 and cleaning doctor 23 all are removably mounted on the cleaning framework 20; Cleaning doctor 23 comprises cleaner scraper blade 23a and cleaning doctor fixed mount 23b; As shown in Figure 7, cleaning doctor 23 is through cleaning doctor fixed mount 23b and 20 fixed installations of cleaning framework.
Fig. 2 and Fig. 3 are respectively the schematic perspective view of developing frame and cleaning framework; Know that by figure 10a is the installation end face of powder delivery cutter 13,10b is the installation end face of developer roll 11; 20a is the installation position of cleaning doctor fixed mount 23b, and 20b is cleaning doctor both side ends installation position.In the prior art; For prevent that the powder delivery cutter from installing between end face 10a and the powder delivery cutter fixed mount 13b, between developer roll installation end face 10b and the developer roll 11, between cleaning doctor both side ends installation position 20b and the cleaning doctor both side ends and leak powder between cleaning doctor fixed mount installation position 20a and the cleaning doctor fixed mount 23b; At the powder delivery cutter end face 10a, developer roll installation end face 10b, cleaning doctor installation position 20a and 20b place are installed the anti-leak-stopping powder of seal is set; Fig. 4 is the part-structure synoptic diagram of the encapsulating method that developing frame adopted in the prior art; Know by figure; On powder delivery cutter installation end face 10a, seal 16 (adopting sponge strip usually) is set; On developer roll installation end face, seal 15 (adopting felt usually) is set, Fig. 5 is installed to the schematic perspective view on the developing frame that is provided with seal for developer roll 11 and powder delivery cutter 13; Fig. 6 is the part-structure synoptic diagram of the cleaning encapsulating method that framework adopted in the prior art; Know by figure; Through being set at cleaning doctor fixed mount installation position 20a, seal 25 (adopting sponge strip usually) seals between cleaning doctor fixed mount 23a and the cleaning framework 20; Because of sponge, felt can only be die-cut into regular shape according to the size of sealing station; Must adopt the sectional type sealing so reach cleaner scraper blade both ends corner between cleaning doctor 23 both ends and the cleaning framework 20; Promptly seal cleaning doctor 23 two ends and be through 20b is provided with that seal 26 (adopting sponge strip usually) seals, two ends corner is provided with seal 27, and (adopting felt usually) seals in the cleaning doctor installation position; The shape need of seal 27 are identical with the shape at the turning, two ends of cleaner scraper blade, and Fig. 7 is installed in the schematic perspective view on the cleaning framework that is provided with seal for cleaning doctor 23.
Above-mentioned seal normally through the gum or the mode of playing glue stick on the surface of position that will seal.The shortcoming that prior art adopts the encapsulating method of sponge, felt to exist:
For reaching good sealing effectiveness; Require seal around the sealing station of framework, could prevent effectively that with seamless contact of framework carbon dust from revealing; Because of sponge, felt can only be die-cut into regular shape according to the size of sealing station; And sponge, felt bullet up and down when being under pressure, paste the end, other positions that are connected are easy to produce the slit and cause leaking powder with framework; And, also can only adopt the sealing of sectional type in the different sealing position that has lap, in the sealing of this sectional type, can there be the slit equally between the different seals and causes leaking powder; And the stickup face of requirement is smooth, otherwise also can produce the slit.
Because the sealing station space of handle box is all narrower usually; For prevent and moulding between produce the slit; Sponge when pasting, must stretchingly make it keep smooth and the moulding adhesive surface will shift to an earlier date clean, and sponge receives tensile to be prone to the distortion that generation can not be restored, and the sponge distortion will have a strong impact on sealing effectiveness; The sponge of distortion just must more be changed and cause waste; Reach desirable sealing effectiveness again at narrow spatial operation like this, production technology and operating personnel are had higher requirement, be unfavorable for the raising of production efficiency and the control of production cost.
The utility model content
The utility model provides a kind of handle box, and the making because of seal causes poorly sealed technical matters of leaking powder easily in the existing handle box to solve.
In order to solve above technical matters, the technical scheme that the utility model is taked is:
