Description

Technical Field

[0001] The invention relates to the technical field of carbon powder cartridges, and in particular to a carbon powder cartridge with a fixing structure. Background Art

[0002] Toner cartridges are a key consumable in laser printers, copiers and all-in-one machines. They contain toner for printing text and images. Toner cartridges are usually composed of a plastic shell, a toner bin, a charging roller, a magnetic stick and other electronic components. During the printing process, the toner is evenly charged and adsorbed on the photosensitive drum, then transferred to the paper through the transfer process, and finally fixed on the paper by the fixing unit through heating to form the final printout.

[0003] Toner cartridges play a vital role in laser printers. However, for ease of installation, existing toner cartridges are usually aligned at the position where the toner cartridge is installed in the laser printer and then pushed into the cartridge bin, or snapped into the inside of the drum holder. This is prone to inaccurate alignment, and the printer often issues a warning that the toner cartridge cannot be detected. As for the positioning of the toner cartridge, the positioning accuracy is poor, and if the toner cartridge is not installed correctly, it may cause unclear printing or toner leakage, which has certain adverse effects on people's use process.

[0037] Among them, positioning grooves 38 are opened on both sides of the top of the right end of the mounting frame 11, and a fixing spring 39 is arranged inside the positioning groove 38. A movable block 310 is fixedly connected to the top of the fixing spring 39. The movable block 310 is movably sleeved inside the positioning groove 38. The movable block 310 is located at the bottom of the right end of the snap hook 37.

[0038] Among them, the snap-on hook 37 is in the shape of a "7", the upper end of the left side of the snap-on hook 37 is in the shape of an arc, and the lower end of the left side of the snap-on hook 37 is provided with a groove, and forms a snap-on hook that is snap-on to the outer surface of the fixed tube 28, the handle 27 is embedded in the top of the snap-on groove 35, and the fixed tube 28 is snap-on to one side of the snap-on hook 37.

[0039] The upper end of the left side of the snap hook 37 is in an arc shape. When the fixed tube 28 is pressed to the left end of the snap hook 37, the snap hook 37 will rotate around the support shaft 36 to compress the fixing spring 39. At this time, when the fixed tube 28 moves to the left side of the snap hook 37, the snap hook 37 will be snapped into the inside of the fixed tube 28 through the reaction force of the fixing spring 39, so that the handle 27 is fixed inside the snap shell 31, and then the right end of the powder box body 2 is fixed inside the snap shell 31, thereby completing the fixation of the right end of the powder box body 2.

[0040] Embodiment 2, as Figure 1 - Figure 4 , Figure 6 - Figure 7 As shown, a toner cartridge with a fixed structure is provided, an open groove 110 is provided at the top of the side of the mounting frame 11 close to the mounting block 16, and movable racks 115 are slidably installed on both sides of the upper end of the mounting frame 11, and the movable rack 115 is slidably installed at the bottom of the open groove 110, a connecting rod 116 is fixedly installed on the right side of the movable rack 115, and a movable frame 1120 is fixedly installed on the end of the connecting rod 116 away from the movable rack 115, and sliding grooves 118 are provided on both sides of the upper right end of the mounting frame 11, and a sleeve ring 117 is fixedly sleeved on the outer surface of one end of the connecting rod 116, and the sleeve ring 117 is slidably installed in the sliding groove 118, and a reset spring 119 is movably sleeved on the outer surface of one end of the connecting rod 116, and the reset spring 119 is located between the left side of the sliding groove 118 and the sleeve ring 117.

[0041] Movable grooves 111 are provided on both sides of the placement groove 13 inside the mounting frame 11, and a support frame 112 is fixedly connected between the movable racks 115 at both ends. A push roller 113 is rotatably installed on the outer surface of the lower end of the support frame 112. The support frame 112 is slidably installed inside the movable groove 111, and the push roller 113 is slidably installed on the left side of the bottom of the powder box body 2.

[0042] By setting the opening groove 110 and the movable rack 115, when the clamping strips 25 at both ends of the support strip 23 are inserted into the interior of the rotating groove 19, the outer surface of the fixed gear 24 will mesh with the top of the movable rack 115. At this time, by rotating the box shell 21, the movable rack 115 will drive the connecting rod 116 to move to the right, and the reset spring 119 will be compressed. At this time, when the powder box body 2 needs to be taken out, the reset spring 119 is reset to make the movable rack 115 push the fixed gear 24 to rotate, and the push roller 113 pushes at the bottom of the box shell 21, so that the box shell 21 automatically rotates and pops out of the interior of the mounting frame 11, thereby facilitating the replacement and disassembly of the powder box body 2.

[0043] Embodiment three, as Figure 1 - Figure 7 As shown, a toner cartridge with a fixed structure is provided, a cavity is opened inside the right side of the mounting frame 11, and an airbag 1121 is placed inside the cavity, the left side of the airbag 1121 is fixedly connected to the movable frame 1120, the right side of the mounting frame 11 is located inside the ventilation groove 114 and is fixedly connected to a ventilation pipe 1123, the top of the right end of the ventilation pipe 1123 is fixedly connected to a connecting nozzle 1124, the bottom of one end of the airbag 1121 is fixedly sleeved on the outer surface of the connecting nozzle 1124, the left end of the ventilation pipe 1123 is fixedly connected to a filter screen 1125, the filter screen 1125 is fixedly installed inside the ventilation groove 114, and the movable frame 1120 is slidably installed on the top of the ventilation pipe 1123.

[0044] By setting up the airbag 1121, while the powder box body 2 is rotated and fixed, the movable rack 115 drives the connecting rod 116 to move through the action of the fixed gear 24, and then the movable frame 1120 drives the airbag 1121 to unfold inside the cavity of the mounting frame 11. The airbag 1121 stores gas inside. When the powder box body 2 automatically rotates and pops out of the mounting frame 11, the airbag 1121 is used for buffering to avoid excessive vibration amplitude during the powder box body 2 bouncing up, resulting in carbon powder spilling. At the same time, when the airbag 1121 is compressed, the internal gas is discharged through the ventilation pipe 1123, blowing out the carbon powder inside the placement groove 13, thereby keeping the inside of the placement groove 13 clean.

[0045] By setting the filter 1125, the ventilation groove 114 on the right side of the ventilation pipe 1123 is prevented from taking in air when the airbag 1121 is deployed, and the carbon powder is intercepted by the filter 1125 to prevent the carbon powder from passing through the filter 1125 and entering the interior of the ventilation pipe 1123 to contaminate the airbag 1121.

[0046] It should be noted that the present invention is a toner cartridge with a fixed structure. When installing, the clamping strips 25 at both ends of the cartridge shell 21 are clamped into the inside of the rotating groove 19 through the slots 17. At this time, the fixed gear 24 passes through the inside of the opening groove 110, and the outer surface of the fixed gear 24 meshes with the top of the moving rack 115. The rotating block 18 is rotated by rotating the cartridge shell 21, so that the clamping strip 25 is locked inside the rotating block 18. During the rotation of the cartridge shell 21, the limiting rib 26 enters the limiting groove 15. The fixing tube 28 at the bottom of the handle 27 is pressed to the left side of the snap hook 37, and the snap hook 37 is squeezed by the arc surface on the left side of the snap hook 37, and rotates around the support shaft 36, and the right end of the snap hook 37 drops, so that the fixing tube 28 moves to the left side of the snap hook 37. At this time, the movable block 310 pushes the snap hook 37 to rotate in the opposite direction through the reaction force of the fixing spring 39, and snaps the fixing tube 28, so that the handle 27 is snapped into the inside of the snap shell 31, and the right end of the powder box body 2 is fixed;

[0047] During the rotation of the box shell 21, the outer surface of the fixed gear 24 meshes with the top of the moving rack 115, and the fixed gear 24 rotates. At this time, the moving rack 115 is pushed to move to the left, and the moving rack 115 pulls the connecting rod 116 to move to the left. The sleeve ring 117 squeezes one end of the return spring 119 to compress the return spring 119. The movable frame 1120 moves with the movement of the connecting rod 116, and the airbag 1121 is deployed. The vent pipe 1123 inhales air and stores the gas inside the airbag 1121.

[0048] When the powder box body 2 needs to be disassembled, the pressing block 33 is pressed to make the pressing block 33 descend and press the right end of the clamping hook 37, and the clamping hook 37 rotates around the support shaft 36, the fixing spring 39 is compressed, and the clamping hook 37 is separated from the side of the fixing tube 28. At this time, the reset spring 119 is reset, which will pull the moving rack 115 to move to the right side, thereby rotating the fixed gear 24 and driving the rotating block 18 to rotate, so that the rotating groove 19 rotates to the corresponding position of the slot 17, so that the box shell 21 automatically rotates and pops out of the inside of the mounting frame 11, and the powder box body 2 can be directly taken out by lifting up the powder box body 2;

[0049] During the process of the powder box body 2 rotating and popping out, in order to avoid the automatic rotation and popping out with excessive force, which causes the carbon powder to spill, when the powder box body 2 rotates and pops out, the reset spring 119 is reset, and the connecting rod 116 will push the movable frame 1120 to squeeze to one side of the airbag 1121, so that the airbag 1121 is compressed, and the gas stored in the airbag 1121 will be discharged from the ventilation groove 114 through the ventilation tube 1123. As the airbag 1121 gradually shrinks, it will buffer the reset spring 119 when it is reset, so that the powder box body 2 rotates and pops out slowly, avoiding the powder box body 2 from being ejected with excessive force. At the same time, the airflow discharged from the ventilation groove 114 passes between the powder box body 2 and the placement groove 13, and blows out the trace carbon powder spilled in the placement groove 13 through the connecting groove 14, thereby keeping the inside of the placement groove 13 clean.
