Description

Technical Field

[0001] This invention relates to the field of developer supply technology, specifically to a developer supply device. Background Technology

[0002] Developer is a chemical used in black and white photography. In the darkroom, it is used to convert the dark areas of an exposed negative or film into a visible image. The role of developer is to restore the silver halide grains in the dark areas of the photosensitive material, making them visible. In equipment such as copiers and printers, the developer supply unit plays a key role in delivering developer stably and evenly to the developing unit.

[0003] However, in some existing supply devices, as the developer is gradually consumed during use, the remaining developer in the powder hopper becomes too low. This leads to uneven distribution of the developer during subsequent transport, resulting in some areas using too much developer while others have insufficient developer. This increases the overall consumption of developer and causes unclear image formation. Furthermore, when the developer is unevenly distributed, it can accumulate on some transport components, increasing the risk of wear and blockage, which can lead to equipment failure or shutdown. Uneven developer transport also results in more waste powder being generated, increasing the difficulty of processing and recycling.

[0004] Secondly, as the supply device operates, it feeds the developer into the equipment. The developer interacts with the electrostatic latent image on the photosensitive drum in the developing unit. The developer is adsorbed onto the electrostatic latent image area on the photosensitive drum to form a visible image. During this process, the drum transfers the developer onto the paper. However, not all the developer is successfully transferred. The excess developer that is not transferred remains inside the drum and eventually accumulates as waste toner. As the waste toner gradually accumulates, the waste toner container will overflow, which will cause the toner to be unable to be collected normally, thus affecting the print quality and causing problems such as blurriness, missing parts, or uneven color.

[0005] Therefore, a developer supply device is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a developer supply device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a developer supply device, comprising a base and a threaded blow-molded bottle, the threaded blow-molded bottle being rotatably connected to the top of the base, a cap being snapped onto the outer wall of the front end of the threaded blow-molded bottle, an inner cap being provided inside the cap, a cover being threadedly connected inside the inner cover, and a soft rubber cover being provided inside the cover; a waste toner hopper is fixedly connected to one side of the top of the base, and a toner storage hopper is fixedly connected to the other side of the top of the base; the toner storage hopper is provided with a toner-uniforming conveying anti-air-drying drum assembly for uniformly distributing the developer; and a waste toner overflow source temporary blocking assembly is provided at the bottom of the base and the middle of the waste toner hopper for temporarily blocking the developer when waste toner overflows, wherein:

[0008] The powder conveying anti-air drum assembly includes four first guide pillars. A rectangular cavity is formed in the middle of the powder storage bin. The four first guide pillars are fixedly connected to the inner walls of the four corners of the rectangular cavity. A first spring is sleeved on the outer wall of each of the four first guide pillars. A material support plate is slidably connected to the outer wall of each of the four first guide pillars. A guide plate is slidably connected to the top of the material support plate. One end of the first spring is fixedly connected to the powder storage bin, and the other end of the first spring is fixedly connected to the material support plate. Transmission gear plates are fixedly connected to both sides of the bottom of the material support plate. Connecting gears are rotatably connected to both sides of the inner wall of the rectangular cavity. The transmission gear plates and connecting gears are meshed together.

[0009] Preferably, a first eccentric wheel is fixedly connected to the middle of the connecting gears on both sides, a spring plate is fixedly connected to the bottom of the guide plate, a square hole is opened in the middle of the material receiving plate, and the spring plate is slidably connected inside the square hole.

[0010] Preferably, a movable seat is fixedly connected to the end of the spring plate away from the guide plate, and the outer walls of the first eccentric wheels on both sides are slidably connected to the middle of the inner wall of the movable seat. A standing seat is fixedly connected to the middle of the inner wall of the rectangular cavity, and the movable seat is slidably connected to the middle of the standing seat.

[0011] Preferably, the waste powder overflow source temporary blocking component includes a trigger plate, which is slidably connected to the middle of the waste powder bin. A second guide post is fixedly connected to each of the four corners of the bottom of the trigger plate. The four second guide posts are slidably connected to the base and the interior of the waste powder bin. A second spring is sleeved on the outer wall of each of the four second guide posts. One end of the second spring is fixedly connected to the trigger plate, and the other end is fixedly connected to the waste powder bin. A contact toothed plate is fixedly connected to the bottom of the trigger plate. A transmission gear is rotatably connected to the inner wall of the bottom of the base near the waste powder bin, and the transmission gear meshes with the contact toothed plate.

[0012] Preferably, a connecting rod is fixedly connected to the middle of the transmission gear, a bearing is fixedly connected to the bottom of the base, and a second eccentric wheel is rotatably connected to the middle of both sides of the bearing. The connecting rod passes through the bearing and is fixedly connected to the second eccentric wheels on both sides.

[0013] Preferably, a first connecting seat is fixedly connected to both sides of the bottom of the base, a main crank connecting rod is rotatably connected to the middle of the first connecting seat on both sides, an elliptical ring plate is fixedly connected to the outer wall of the main crank connecting rod on both sides away from the first connecting seat, and the outer walls of the second eccentric wheels on both sides are slidably connected to the inner walls of the elliptical ring plates on both sides.

[0014] Preferably, a second connecting seat is fixedly connected to both sides of the bottom of the base, and a secondary crank connecting rod is rotatably connected to the middle of both sides of the second connecting seat.

[0015] Preferably, one end of the auxiliary crank connecting rod on one side, away from the second connecting seat, is rotatably connected to the trigger plate, and the other end of the auxiliary crank connecting rod on the other side, away from the second connecting seat, is rotatably connected to a baffle plate, which is slidably connected inside the base and the powder storage bin.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. As the developer in the powder storage hopper is gradually consumed or replenished, the change in developer quantity causes the support plate to rise and fall vertically, which in turn causes the first spring to deform. Through the cooperation of the transmission gear plates on both sides, the connecting gear rotates, which in turn causes the first eccentric wheel connected to the connecting gear to rotate synchronously. During the rotation, the movable seat is pushed left and right, so that it corresponds to the conveying and supplying part of the threaded blow-molded bottle in the longitudinal direction. The developer above the support plate and the guide plate is slightly shaken back and forth, which evenly disperses the developer above the guide plate with the two staggered circular grooves. Corresponding to the conveying and supplying area of ​​the threaded blow-molded bottle, the developer is evenly distributed in the threaded groove of the threaded blow-molded bottle. The developer is then further conveyed to the developing unit, ensuring clear and uniform image imaging.

[0018] 2. By setting a toner level triggering component inside the waste toner hopper, as excess developer that cannot be transferred or scraped off by the blade gradually accumulates in the waste toner hopper, a second spring with corresponding stiffness is set in the waste toner hopper to warn of excessive waste toner. When the waste toner is stored in excess, the trigger plate will be pressed down. With the meshing of the contact tooth plate and the transmission gear, the second eccentric wheels set on both sides of the shaft seat will rotate. The second eccentric wheels set on opposite sides of the shaft will rotate with the transmission gear through the connecting rod. With the assistance of the main crank connecting rod and the auxiliary crank connecting rod on both sides, the baffle plate will be pushed upward to block the developer powder on the guide plate and suspend the delivery of developer powder to the threaded blow molding bottle. This temporarily cuts off the source of developer powder during the printing process. In contrast to the existing technology where the imaging device will issue a warning when the waste toner hopper is full, after the waste toner in the hopper is manually cleaned, the trigger plate will move upward accordingly, which will then retract the baffle plate on the other side downward to continue the supply and delivery of developer.

[0019] 3. The developer is supplied via a threaded blow-molded bottle. The developer is replenished by inserting the pipe directly into the center hole of the inner cap. The inner cap can accommodate developer pipes of various sizes, making replenishment more convenient and efficient. The printer's internal drive mechanism attaches the head cap, causing the threaded blow-molded bottle to rotate 180 degrees back and forth. This cyclical motion pushes the developer. The inner cap also stirs the developer during this cyclical motion, preventing localized buildup that could hinder the smooth delivery of the developer. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0037] Please see Figures 1 to 12An embodiment of the present invention provides a developer supply device, comprising a base 1 and a threaded blow-molded bottle 2. The threaded blow-molded bottle 2 is rotatably connected to the top of the base 1. A cap 5 is snapped onto the outer wall of the front end of the threaded blow-molded bottle 2. An inner cap 6 is provided inside the cap 5. A cover 7 is threadedly connected inside the inner cap 6. A soft rubber cover 8 is provided inside the cover 7. A waste toner hopper 3 is fixedly connected to one side of the top of the base 1, and a toner storage hopper 4 is fixedly connected to the other side of the top of the base 1. The toner storage hopper 4 is provided with a toner distribution and anti-air-drying drum assembly for uniformly distributing the developer. A waste toner overflow source temporary blocking assembly is provided at the bottom of the base 1 and the middle of the waste toner hopper 3 for temporarily blocking the developer when the waste toner overflows.

[0038] The powder conveying anti-air drum assembly includes four first guide pillars 92. A rectangular cavity 91 is opened in the middle of the powder storage bin 4. The four first guide pillars 92 are fixedly connected to the inner walls of the four corners of the rectangular cavity 91. A first spring 93 is sleeved on the outer wall of each of the four first guide pillars 92. A material support plate 94 is slidably connected to the outer wall of the four first guide pillars 92. A guide plate 95 is slidably connected to the top of the material support plate 94. One end of the first spring 93 is fixedly connected to the powder storage bin 4, and the other end of the first spring 93 is fixedly connected to the material support plate 94. A transmission gear plate 910 is fixedly connected to both sides of the bottom of the material support plate 94. A connecting gear 911 is rotatably connected to both sides of the inner wall of the rectangular cavity 91. The transmission gear plate 910 and the connecting gear 911 are meshed together.

[0039] Among them: the head cover 5 is designed in the shape of a lotus tooth groove, and the top of the guide plate 95 has two corresponding staggered grooves, which can evenly distribute the developer powder.

[0040] Even better: The internal drive locking structure of the imaging device adheres to the head cover 5, which drives the threaded blow-molded bottle 2 to rotate back and forth 180 degrees in a cyclic reciprocating motion to push the developer powder. After a certain amount of developer powder is added into the powder storage hopper 4, as the supply continues, the capacity of the developer powder will gradually decrease, and the downward pressure on the support plate 94 will gradually decrease. As a result, the squeezing force generated by the support plate 94 on each first spring 93 will also weaken. The first spring 93 can slowly expand upward along each first guide post 92 as the support plate 94 moves upward. As the support plate 94 moves upward, with the cooperation of the transmission gear plates 910 fixedly connected on both sides, it can drive the corresponding meshing connecting gear 911 to rotate synchronously.

[0041] A first eccentric wheel 912 is fixedly connected to the middle of the connecting gears 911 on both sides. A spring plate 96 is fixedly connected to the bottom of the guide plate 95. A square hole 97 is opened in the middle of the material receiving plate 94. The spring plate 96 is slidably connected inside the square hole 97. A movable seat 99 is fixedly connected to the end of the spring plate 96 away from the guide plate 95. The outer walls of the first eccentric wheels 912 on both sides are slidably connected to the middle of the inner wall of the movable seat 99. A standing seat 98 is fixedly connected to the middle of the inner wall of the rectangular cavity 91. The movable seat 99 is slidably connected to the middle of the standing seat 98.

[0042] Among them, the center points of the upright 98, the movable seat 99, the spring plate 96, the material support plate 94, and the guide plate 95 are all located on the same vertical straight line.

[0043] Even better: The first eccentric wheels 912 on both sides rotate with the corresponding connecting gears 911 on both sides inside the rectangular cavity 91, and the eccentric shafts on the outer walls of the first eccentric wheels 912 on both sides are all installed through the middle of the inner wall of the movable seat 99. As the first eccentric wheels 912 on both sides rotate, the movable seat 99 can move back and forth along the longitudinal direction of the threaded blow-molded bottle 2, and slide back and forth in the middle of the stand 98. With the connection and cooperation of the spring plate 96, the guide plate 95 can move back and forth synchronously on the top of the support plate 94, so that the developer powder above the support plate 94 can be shaken back and forth to a certain extent to a uniform state. The grooves on the guide plate 95 are staggered and correspond to the threaded feeding area of ​​the threaded blow-molded bottle 2, so that the developer powder can be evenly delivered to the threaded grooves on the outer wall of the threaded blow-molded bottle 2, so that the powder can be evenly supplied to the developing unit of the imaging equipment, ensuring the clarity of the final image.

[0044] The waste powder overflow temporary blocking component includes a trigger plate 101, which is slidably connected to the middle of the waste powder bin 3. Second guide posts 102 are fixedly connected to the four corners of the bottom of the trigger plate 101. The four second guide posts 102 are slidably connected to the interior of the base 1 and the waste powder bin 3. Second springs 103 are sleeved on the outer walls of the four second guide posts 102. One end of the second spring 103 is fixedly connected to the trigger plate 101, and the other end of the second spring 103 is fixedly connected to the waste powder bin 3. A contact toothed plate 104 is fixedly connected to the bottom of the generating plate 101. A transmission gear 105 is rotatably connected to the inner wall of the bottom of the base 1 near the waste powder bin 3. The transmission gear 105 is meshed with the contact toothed plate 104. A connecting rod 107 is fixedly connected to the middle of the transmission gear 105. A bearing seat 106 is fixedly connected to the bottom of the base 1. A second eccentric wheel 108 is rotatably connected to the middle of both sides of the bearing seat 106. The connecting rod 107 passes through the bearing seat 106 and is fixedly connected to the second eccentric wheels 108 on both sides.

[0045] Among them: the stiffness of the second spring 103 is set to correspond to the warning capacity of the waste powder inside the waste powder bin 3, and the eccentric shafts on the outer walls of the two second eccentric wheels 108 are arranged in opposite symmetrical ways when stationary.

[0046] Even better: As the waste powder capacity inside the waste powder bin 3 gradually increases, when the waste powder reaches the warning level, the stiffness of the second spring 103 is insufficient to support the waste powder inside the waste powder bin 3, which will exert downward pressure on the trigger plate 101. Under the guidance of the four side second guide posts 102, the trigger plate 101 moves downward, and can then move downward synchronously through the contact tooth plate 104, and drive the transmission gear 105 meshing with the contact tooth plate 104 to rotate. At this time, the second eccentric wheels 108 on both sides can be driven to rotate in the middle of both sides of the bearing seat 106 through the connecting rod 107 connected to the transmission gear 105, preparing for subsequent adjustment operations.

[0047] Both sides of the bottom of the base 1 are fixedly connected to the first connecting seat 109. The middle of the first connecting seat 109 on both sides is rotatably connected to the main crank connecting rod 1010. The outer wall of the main crank connecting rod 1010 on both sides away from the first connecting seat 109 is fixedly connected to the elliptical ring plate 1011. The outer wall of the second eccentric wheel 108 on both sides is slidably connected to the inner wall of the elliptical ring plate 1011 on both sides. Both sides of the bottom of the base 1 are fixedly connected to the second connecting seat 1012. The middle of the second connecting seat 1012 on both sides is rotatably connected to the auxiliary crank connecting rod 1013. One end of the auxiliary crank connecting rod 1013 away from the second connecting seat 1012 is rotatably connected to the trigger plate 101. The other end of the auxiliary crank connecting rod 1013 away from the second connecting seat 1012 is rotatably connected to the baffle plate 1014. The baffle plate 1014 is slidably connected inside the base 1 and the powder storage bin 4.

[0048] Among them: the top of the barrier plate 1014 is flush with the inner wall of the powder storage bin 4 in the default state;

[0049] Even better: The two second eccentric wheels 108, which are symmetrically arranged on opposite sides of the eccentric shaft, can act on the inner walls of the two elliptical ring plates 1011 through the two eccentric shafts during rotation. As the elliptical ring plates 1011 change their tilt in the vertical direction, they further drive the main crank connecting rod 1010 and the auxiliary crank connecting rod 1013 to achieve different degrees of angle opening and closing in the vertical direction. With the assistance of the first connecting seat 109 and the second connecting seat 1012 on both sides, the baffle plate 1014 can be driven to move upward and gradually push out to the inner wall plane of the powder storage bin 4, thereby temporarily blocking the developer powder inside the powder storage bin 4, avoiding the continuous conveying of powder, and thus preventing more waste powder from being generated during the conveying process, causing the waste powder in the waste powder bin 3 to overflow.

[0050] The working principle of the above implementation is as follows:

[0051] The initialization steps are as follows:

[0052] A certain amount of developer powder is injected into the powder storage bin 4, and the trigger plate 101 is suspended in the air inside the waste powder bin 3 under the support of the second spring 103. Correspondingly, the top of the barrier plate 1014 is flush with the inner wall of the powder storage bin 4 and stored at the bottom of the base 1.

[0053] The operation steps are as follows:

[0054] like Figure 1 - Figure 7 As shown, the internal drive and locking structure of the imaging device adheres to the head cover 5, driving the threaded blow-molded bottle 2 to rotate 180 degrees back and forth in a cyclic reciprocating motion to push the developer powder. After a certain amount of developer powder is added into the powder storage hopper 4, as the supply continues, the capacity of the developer powder will gradually decrease, and the downward pressure on the support plate 94 will gradually decrease. As a result, the squeezing force exerted by the support plate 94 on each of the first springs 93 will also weaken. The first springs 93 can slowly expand upward along each of the first guide posts 92 as the support plate 94 moves upward. As the support plate 94 moves upward, with the cooperation of the transmission gear plates 910 fixedly connected on both sides, it can drive the corresponding meshing connecting gears 911 to rotate synchronously. The first eccentric wheels 912 on both sides rotate inside the rectangular cavity 91 along with the corresponding connected connecting gears 911 on both sides, and the eccentric shafts on the outer walls of the first eccentric wheels 912 on both sides are all inserted through the middle of the inner wall of the movable seat 99. As the first eccentric wheels 912 on both sides rotate, the movable seat 99 moves back and forth along the longitudinal direction of the threaded blow-molded bottle 2, sliding back and forth in the middle of the upright seat 98. With the connection and cooperation of the spring plate 96, the guide plate 95 moves back and forth synchronously on the top of the support plate 94, thereby shaking the developer powder above the support plate 94 back and forth to a certain extent to a uniform state. The grooves on the guide plate 95 are staggered and correspond to the threaded feeding area of ​​the threaded blow-molded bottle 2, so that the developer powder can be evenly distributed in the interior of each groove. This allows the developer powder to be evenly conveyed to the threaded groove on the outer wall of the threaded blow-molded bottle 2, so that the powder can be evenly supplied to the developing unit of the imaging equipment, ensuring the clarity of the final image.

[0055] like Figure 7 - Figure 8As shown, during the process of conveying developer powder via the threaded blow-molded bottle 2, the scraper in the printer drum evenly scrapes the powder on the outer wall of the conveyor roller during the conveying process, scraping off excess powder and causing it to fall into the waste powder bin 3. As the waste powder capacity inside the waste powder bin 3 gradually increases, when the waste powder reaches the warning level, the stiffness of the second spring 103 is insufficient to support the waste powder in the waste powder bin 3. The excessive waste powder will exert downward pressure on the trigger plate 101 under the action of gravity, guided by the second guide posts 102 on all four sides. When the trigger plate 101 moves downward, it can move downward synchronously through the contact tooth plate 104 and drive the transmission gear 105 that meshes with the contact tooth plate 104 to rotate. At this time, the second eccentric wheels 108 on both sides can be driven to rotate in the middle of both sides of the bearing seat 106 through the connecting rod 107 connected to the transmission gear 105, in preparation for subsequent adjustment operations. The second eccentric wheels 108 on both sides, which are symmetrically arranged with opposite eccentric shafts, can act on the inner wall of the elliptical ring plate 1011 on both sides through the eccentric shafts on both sides during rotation.

[0056] like Figure 7 - Figure 12 As shown, as the elliptical ring 1011 tilts vertically, it further drives the main crank connecting rod 1010 and the secondary crank connecting rod 1013 to open and close at different angles in the vertical direction. Corresponding slides of the same shape are provided at the positions of the baffle plate 1014 inside the base 1 and the toner storage chamber 4. With the assistance of the first connecting seat 109 and the second connecting seat 1012 on both sides, the baffle plate 1014 can be moved upwards, gradually pushing out to the inner wall plane of the toner storage chamber 4, thereby realizing the development of the developer inside the toner storage chamber 4. The powder is temporarily blocked to prevent continuous powder conveying, which would generate more waste powder during the conveying process and cause the waste powder in the waste powder bin 3 to overflow. Correspondingly, in the prior art, when there is too much powder in the waste powder bin 3, an alarm is usually issued to prevent leakage. At this time, after the waste powder in the waste powder bin 3 is manually processed, the trigger plate 101 will move upward to return to its original position, and the corresponding blocking plate 1014 in the powder storage bin 4 will also move downward to retract to its original position, so that the powder in the powder storage bin 4 can be further conveyed and supplied.
