Description

Technical Field

[0001] This invention relates to the field of developer cartridge technology, and more specifically to a developer cartridge that inhibits developer residue. Background Technology

[0002] Previously, image forming apparatuses were known to include a developer container that internally holds developer. The image forming apparatus includes a carrier, a developing unit, and a developer container. If developer is supplied from the developing unit to the image carrier, the electrostatic latent image formed on the image carrier is developed into a developer image. The developer container has a developer outlet to supply additional developer to the replenishment port of the developing unit. Additionally, there are currently developer containers equipped with a stirring shaft, on which a toner delivery element is installed; this element is typically made of PET.

[0003] In the prior art, under the above configuration, the toner delivery element on the stirring shaft is likely to fall off and wear, resulting in insufficient powder scraping force and insufficient developer delivery force, thus causing insufficient utilization of developer and resulting in residue.

[0004] In addition, the current developer cartridges have irregular shapes in their outer shells to match the equipment, which may cause bulges inside the shell. Therefore, during the stirring process, the developer may be located in the irregular corners and edges, making it difficult to scrape off and creating scraping dead spots.

[0005] In view of this, the present invention proposes a developer cartridge for suppressing developer residue to compensate for and improve the deficiencies of the prior art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a developer cartridge that can improve the full utilization rate of the developer, maintain the effectiveness of the device in a timely manner, and further enhance the effect of suppressing residue, thereby solving the corresponding technical problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a developer cartridge for inhibiting developer residue, comprising a housing, a pair of connection ports on the top of the housing, a base plate detachably connected to the bottom of the housing, a leak-proof strip fixedly connected to the top edge of the base plate, a convex shell fixedly connected to the middle of the base plate, and a pair of rotating shafts rotatably connected to the top of the base plate, and further comprising:

[0008] A powerful scraping mechanism is used to enhance the removal of developer from the substrate surface and to accurately assess the wear and tear of the scraping tools.

[0009] The edge residue suppression mechanism is used to repeatedly push the developer at the edges of the base plate during agitation.

[0010] Preferably, the strong scraping mechanism includes a hard plate fixedly connected to the top of the rotating shaft. The hard plate is provided in pairs. The outer walls of each pair of hard plates are fixedly connected to soft plates. The bottom of each pair of soft plates is slidably connected to a pair of telescopic plates. The bottoms of the two pairs of telescopic plates slidably abut against the outer walls of the base plate and the convex shell.

[0011] Preferably, the strong scraping mechanism further includes a pair of first fixing plates fixedly connected to both sides of the bottom of the hard plate. There are two pairs of first fixing plates. The inner walls of the two pairs of first fixing plates are slidably connected to limit rods. The outer walls of the two pairs of limit rods are movably sleeved with first springs. The tops of the two pairs of first springs are fixedly connected to the bottom of the first fixing plates. The bottoms of the first springs are fixedly connected to second fixing plates. The outer walls of the two pairs of limit rods are fixedly connected to the outer walls of the telescopic plate. The bottoms of the limit rods are fixedly connected to the tops of the second fixing plates.

[0012] Preferably, the strong scraping mechanism also includes an alarm fixedly connected to the bottom of the hard plate. There are two pairs of alarms, and the bottom of each pair of alarms is fixedly connected to the outer wall of the first fixed plate. A button is fixedly connected to the side of each alarm near the limiting rod, and an anti-detachment squeezing plate is fixedly connected to the top of each limiting rod.

[0013] Preferably, the mechanism for suppressing corner residue includes an irregularly shaped shovel plate slidably connected to the edge of the base plate. A pair of rotating rods are rotatably connected to the middle of the irregularly shaped shovel plate. A triangular scraper is rotatably connected to the side of the pair of rotating rods away from the irregularly shaped shovel plate. The bottom of the triangular scraper is slidably connected to the outer wall of the convex shell. A second spring is fixedly connected to the bottom of each rotating rod. The side of the second spring away from the rotating rod is fixedly connected to the edge of the convex shell.

[0014] Preferably, the mechanism for suppressing corner residue also includes multiple fixing rods fixedly connected to the top of the irregularly shaped shovel plate, and each fixing rod has a rotating blade rotatably connected to its outer wall.

[0015] Preferably, the shape of the irregularly shaped shovel plate is consistent with the shape of the edge of the base plate, and the irregularly shaped shovel plate is inclined on the side near the leak-proof strip.

[0016] Preferably, both pairs of telescopic plates are arranged in a centrally symmetrical manner with the pivot axis as the center.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When the shaft rotates, the strong scraping mechanism synchronously drives the flexible plate and the telescopic plate to rotate. The first spring keeps the telescopic plate in contact with the surface of the bottom plate and the convex shell, avoiding gaps. It powerfully scrapes away the developer from the surface of both, preventing residue on irregular parts of the shell wall, improving the full utilization rate of the developer, and thus increasing the uniformity of developer delivery. This avoids problems such as insufficient scraping force and insufficient developer delivery force.

[0019] 2. Due to the setting of the limit rod, when the telescopic plate abuts against the surface of the base plate and the convex shell, there will be continuous friction and wear. When the telescopic plate wears down or breaks, the elastic force of the first spring will cause the anti-detachment squeezing plate at the top of the limit rod to trigger the alarm, reminding the user to replace the telescopic plate so as to maintain the effectiveness of the device in a timely manner.

[0020] 3. When the flexible plate rotates, the mechanism for suppressing residue at the edges and corners simultaneously squeezes the triangular scraper, causing it to move towards the shaped spatula. The bottom of the triangular scraper scrapes away the developer along the slope of the convex shell, reducing the dead corners of the convex shell. It also moves the shaped spatula closer to the corners of the leak-proof strip. Since the shape of the shaped spatula matches the shape of the bottom plate edge and its side is tilted near the leak-proof strip, it can scrape away the developer at the irregular corners of the bottom plate edge. Combined with the rotating blade, it helps to rotate the bottom developer out, further increasing the effect of suppressing residue. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Embodiments of the present invention

[0035] Please refer to Figures 1 to 8 As shown, a developer cartridge for inhibiting developer residue includes a housing 1, a pair of connection ports 2 on the top of the housing 1, a base plate 3 detachably connected to the bottom of the housing 1, a leak-proof strip 4 fixedly connected to the top edge of the base plate 3, a protruding shell 5 fixedly connected to the middle of the base plate 3, and a pair of rotating shafts 6 rotatably connected to the top of the base plate 3. It also includes:

[0036] The strong scraping mechanism 7 is used to enhance the scraping of the developer on the surface of the base plate 3 and to accurately judge the wear of the scraping tool;

[0037] The corner retention suppression mechanism 8 is used to repeatedly push the developer at the corners of the bottom plate 3 during the agitation process;

[0038] The strong scraping mechanism 7 includes a hard plate 71 fixedly connected to the top of the rotating shaft 6. A pair of hard plates 71 are provided. A soft plate 72 is fixedly connected to the outer wall of each pair of hard plates 71. A pair of telescopic plates 73 are slidably connected to the bottom of each pair of soft plates 72. The bottom of each pair of telescopic plates 73 slides against the outer wall of the base plate 3 and the convex shell 5.

[0039] The strong scraping mechanism 7 also includes a pair of first fixing plates 78 fixedly connected to both sides of the bottom of the hard plate 71. There are two pairs of first fixing plates 78. The inner walls of the two pairs of first fixing plates 78 are slidably connected to limit rods 75. The outer walls of the two pairs of limit rods 75 are movably sleeved with first springs 74. The tops of the two pairs of first springs 74 are fixedly connected to the bottom of the first fixing plate 78. The bottoms of the first springs 74 are fixedly connected to second fixing plates 79. The outer walls of the two pairs of limit rods 75 are fixedly connected to the outer walls of the telescopic plate 73. The bottoms of the limit rods 75 are fixedly connected to the tops of the second fixing plates 79.

[0040] The strong scraping mechanism 7 also includes an alarm 76 fixedly connected to the bottom of the hard plate 71. There are two pairs of alarms 76. The bottom of both pairs of alarms 76 is fixedly connected to the outer wall of the first fixed plate 78. A button 77 is fixedly connected to the side of the alarm 76 near the limit rod 75. An anti-detachment squeezing plate is fixedly connected to the top of the limit rod 75.

[0041] Both pairs of telescopic plates 73 are arranged symmetrically around the pivot 6.

[0042] Among them, the rigid plate 71 is located entirely above the convex shell 5 to prevent the convex shell 5 from obstructing the rotation of the rigid plate 71, and the alarm 76 is electrically connected to the equipment control system.

[0043] The effects achieved by this embodiment are as follows: In the prior art, the toner delivery element on the stirring shaft has a certain probability of falling off and wearing out, resulting in insufficient scraping force and insufficient delivery force of developer, thus making insufficient utilization of developer and causing residue. Compared with the prior art, through the implementation of this embodiment, the strong scraping mechanism 7 can drive the flexible plate 72 and the telescopic plate 73 to rotate, and the first spring 74 is used to keep the telescopic plate 73 in contact with the surface of the bottom plate 3 and the convex shell 5 at all times, avoiding gaps, and forcefully scraping the developer from the surface of both, preventing the irregular parts of the shell wall from being left behind, and triggering the alarm 76 for timely maintenance when the telescopic plate 73 is worn down or broken.

[0044] Further examples:

[0045] Please refer to Figures 4 to 5 As shown, the corner residue suppression mechanism 8 includes an irregularly shaped shovel plate 83 slidably connected to the edge of the base plate 3. A pair of rotating rods 82 are rotatably connected to the middle of the irregularly shaped shovel plate 83. A triangular scraper 81 is rotatably connected to the side of the pair of rotating rods 82 away from the irregularly shaped shovel plate 83. The bottom of the triangular scraper 81 is slidably connected to the outer wall of the convex shell 5. A second spring 86 is fixedly connected to the bottom of each rotating rod 82. The side of the second spring 86 away from the rotating rod 82 is fixedly connected to the edge of the convex shell 5.

[0046] The corner residue suppression mechanism 8 also includes multiple fixing rods 84 fixedly connected to the top of the irregular shovel plate 83, and the outer walls of the fixing rods 84 are rotatably connected to rotating blades 85;

[0047] The shape of the irregular shovel plate 83 is consistent with the shape of the edge of the base plate 3, and the irregular shovel plate 83 is inclined on the side near the leak-proof edge strip 4;

[0048] Wherein: the triangular base of the triangular scraper 81 is set toward the soft plate 72 to increase the contact time between the triangular scraper 81 and the soft plate 72, so as to squeeze the triangular scraper 81 to slide.

[0049] The effects achieved by this embodiment are as follows: In the prior art, in order to match the equipment, the shape of its outer shell is partially irregular, which may cause bulges inside the shell. Therefore, during the stirring process, the developer may be located at irregular corners, which is difficult to scrape off, resulting in scraping dead corners. Compared with the prior art, through the implementation of this embodiment, the corner residue suppression mechanism 8 can simultaneously squeeze the triangular scraper 81 when the flexible plate 72 rotates, so that the triangular scraper 81 moves towards the irregular shovel 83. The bottom of the triangular scraper 81 scrapes off the developer along the slope of the convex shell 5, reducing the scraping dead corners of the convex shell 5. In addition, the irregular shovel 83 is moved closer to the corners of the leak-proof strip 4 to scrape off the developer at the irregular corners of the bottom plate 3.

[0050] The complete usage steps and working principle of the above embodiments are as follows:

[0051] In the initial state: the telescopic plates 73 are all in contact with the surface of the base plate 3, the first spring 74 and the second spring 86 are in a naturally relaxed state, the irregular shovel plate 83 is in a position close to the convex shell 5, and the triangular scraper 81 is located on the top of the convex shell 5.

[0052] In use, when the two rotating shafts 6 rotate and drive the rigid plate 71 to rotate, the flexible plate 72 can be driven to rotate simultaneously, thereby causing the two pairs of telescopic plates 73 to rotate synchronously. When the bottom of the telescopic plate 73 passes the convex shell 5, it is squeezed upward and then compressed into the first spring 74. When the telescopic plate 73 reaches the surface of the bottom plate 3, the elastic force of the first spring 74 causes the telescopic plate 73 to return to its original position. In this way, during the rotation of the flexible plate 72, the first spring 74 keeps the telescopic plate 73 in contact with the surfaces of the bottom plate 3 and the convex shell 5, powerfully scraping off the developer on both surfaces and effectively preventing developer residue from remaining on irregular parts of the shell wall.

[0053] Furthermore, as the telescopic plate 73 wears down due to friction, its length may shorten or it may break. In order to make the bottom of the telescopic plate 73 abut against the outer wall of the base plate 3 and the convex shell 5, the elastic force of the first spring 74 can make the limiting rod 75 continue to move towards the telescopic plate 73 until the anti-detachment squeezing plate at the top of the limiting rod 75 reaches the alarm 76 and the button 77 is squeezed to trigger the alarm 76. The alarm 76 transmits the alarm signal to the external equipment control system to remind the user to replace the telescopic plate 73.

[0054] Please refer to the above work process. Figures 1 to 4 , Figures 6 to 8 .

[0055] Furthermore, when the flexible plate 72 rotates, it can simultaneously squeeze the triangular scraper 81, causing the triangular scraper 81 to move towards the irregular shovel 83. The bottom of the triangular scraper 81 scrapes away the developer along the slope of the convex shell 5, reducing the dead angle of the convex shell 5. Then, the triangular scraper 81 drives the rotating rod 82 to squeeze towards the irregular shovel 83. The rotating rod 82 stretches the second spring 86. Under the push of the rotating rod 82, the irregular shovel 83 moves closer to the corner of the leak-proof strip 4. Since the shape of the irregular shovel 83 is consistent with the shape of the edge of the bottom plate 3, and its side close to the leak-proof strip 4 is inclined, the developer at the irregular corner of the bottom plate 3 can be scraped away. With the setting of the rotating blade 85, under the action of inertia, the rotating blade 85 can be driven to rotate, which helps to rotate the bottom developer out.

[0056] Please refer to the above work process. Figures 4 to 5 .
