As the core consumable component of laser printer, selenium drum bears the key functions of charge adsorption, toner transfer and image fixation. The fluidity of toner inside the selenium drum directly affects the printing quality and equipment stability. In the process of laser printing, selenium drum forms latent image by electrostatic adsorption of toner to the surface of photosensitive drum, and then realizes text and image output through high-temperature fixation. This process puts strict requirements on the fluidity, particle uniformity and environmental adaptability of toner.

DETAILED DESCRIPTION

[0020] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0021] Example: A highly fluid toner cartridge, such as Figures 1-4 As shown, the printer includes a toner hopper 1, a toner dispensing assembly 2, a mounting base 3, a mounting plate 4, a moving block 6, a screw 7, a fixing screw 8, a vibrator 9, and a cover plate 10. The toner hopper 1 is installed inside the printer. The toner dispensing assembly 2 for printing is installed at the lower end of the toner hopper 1. The mounting base 3 is connected to both the front and rear sides of the toner hopper 1. The two ends of the mounting plate 4 are slidably connected to the two mounting bases 3. The mounting plate 4 has several slots 5 with staggered openings at the ends. The ends of two adjacent slots 5 are located at the two ends of the mounting plate 4. This structure can distribute the stress points of the mounting plate 4, improve the overall strength, and avoid local stress concentration. The moving block 6 is slidably connected to the slots 5. The top of the moving block 6 is connected to a screw 7. The top of the screw 7 passes through the mounting plate 4 and is threaded with a fixing screw 8. A vibrator 9 is installed at the bottom of each moving block 6. The length of the vibrator 9 matches the internal shape of the toner hopper 1. A removable cover plate 10 is provided on the top of the toner hopper 1.

[0022] like Figure 1 and Figure 3 As shown, it also includes a connecting block 11, a lead screw 12, and a motor 13. The lead screw 12 is rotatably connected inside the fixed base 3. The front and rear ends of the mounting plate 4 are both connected to the connecting blocks 11 that are threaded to the lead screw 12. The motor 13 is installed on the side of the powder hopper 1. The output shaft of the motor 13 is connected to the end of the lead screw 12. The two lead screws 12 are synchronously transmitted through a belt pulley set. The motor 13 drives the lead screw 12 to reciprocate in both directions. Through the connecting block 11, the mounting plate 4 is driven to reciprocate in the powder hopper 1. The vibrating rod 9 moves left and right to stir the toner.

[0023] like Figure 3 As shown, it also includes a rubber pad 14. The mounting plate 4 has a slot 5 for connecting the rubber pad 14, and the top surface of the moving block 6 is pressed and engaged with the rubber pad 14.

[0024] like Figure 2 and Figure 4As shown, the device further comprises a guide plate 15 connected to the bottom surface of the cover plate 10, the guide plate 15 on the bottom surface of the cover plate 10 is in sliding fit with the inner side of the top of the powder tank 1, the guide plate 15 is made of wear-resistant resin material, and its low friction coefficient ensures smooth sliding and accurate positioning, realizing fast and accurate installation of the cover plate 10.

[0025] As shown, Figure 4 As shown, the device further comprises a sealing gasket 16 connected to the inner ring of the top surface of the powder tank 1, the sealing gasket 16 is in extrusion fit with the cover plate 10, the sealing gasket 16 is made of silicone rubber material and has good elastic recovery ability, which can form a sealed space to prevent carbon powder leakage.

[0026] As shown, Figure 2 As shown, the device further comprises a telescopic pad 17 provided at both ends of the fixed seat 3 to slide in the space of the closed connecting block 11, one end of the telescopic pad 17 is connected to the fixed seat 3, and the other end is connected to the mounting plate 4, the telescopic pad 17 is made of flexible nylon cloth material and realizes dynamic balance by elastic deformation in the sliding space of the closed connecting block 11 and ensures smooth movement of the mounting plate 4.

[0027] The powder tank 1 installed with several vibration rods 9 is stably embedded in the printer, the length of the vibration rod 9 is precisely adapted to the arc-shaped contour of the inside of the powder tank 1, ensuring that the vibration energy is transmitted without dead angle. The several clamping grooves 5 opened in the mounting plate 4 are designed with open ends staggered, and the ends of adjacent clamping grooves 5 are respectively located at the left and right ends of the mounting plate 4. This layout improves the overall strength of the mounting plate 4 by dispersing stress points and effectively avoids structural deformation caused by local stress concentration. During installation, the operator pushes the moving block 6 along the clamping groove 5 to the preset position, rotates the fixing screw 8 at the top end of the screw rod 7, and the fixing screw 8 forms a bidirectional extrusion on the mounting plate 4 during the tightening process, which synchronously triggers the elastic deformation of the rubber pad 14. The pre-tightening force generated by this deformation can offset the dynamic impact of the vibration rod 9 during work, ensuring that it does not loosen during long-term use.

[0028] After the carbon powder is uniformly injected into the powder bin 1, the cover plate 10 is precisely positioned by the sliding fit between the bottom guide plate 15 and the top inner side of the powder bin 1, and the arc-shaped curved surface design of the guide plate 15 can guide the cover plate 10 to be smoothly pressed down. During the screw fastening process, the silicone rubber sealing gasket 16 on the inner ring of the top surface of the powder bin 1 forms an elastic sealing surface with the edge of the cover plate 10, which can ensure the airtightness and avoid excessive extrusion to cause the deformation of the cover plate 10. After the printing is started, the vibration rod 9 rotates at a specific frequency, and the loose carbon powder particles are settled downward and the large particles are floated upward by the centrifugal force, so that real-time dynamic screening is realized; at the same time, the micro-vibration energy can disperse the agglomerated large particles into independent carbon powder units, which can significantly improve the flowability and utilization rate of the carbon powder. At this time, the motor 13 drives the lead screw 12 to reciprocally rotate in the forward and reverse directions, and the connecting block 11 drives the mounting plate 4 to slide horizontally on the guide rail of the fixed seat 3, so that the vibration rod 9 can complete the horizontal stirring action while vertically vibrating, thereby forming a three-dimensional carbon powder processing effect. When the mounting plate 4 moves, the two sides of the telescopic pad 17 are deformed by the flexible nylon cloth, and the covering area of the opening of the fixed seat 3 is dynamically adjusted under the premise of keeping the sliding space closed, which can effectively block the carbon powder from invading the transmission mechanism, ensure the precise fit between the connecting block 11 and the lead screw 12, and prolong the service life of the whole device.

[0029] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
