Description

Technical Field

[0001] The invention relates to the technical field of developer supplying, in particular to a developer supplying device. Background Art

[0002] Developer is a chemical used in black and white photography. It is used in the darkroom to convert the dark image on the exposed negative or film into a visible image. The function of the developer is to restore the silver salt grains in the dark shadow part of the photosensitive material to make it visible. In equipment such as copiers and printers, the developer supply device plays a key role in stably and evenly delivering the developer to the developing unit.

[0003] However, in the prior art, when some supply devices are feeding and conveying the developer, as the developer is gradually consumed during use, there is too little remaining developer in the powder bin, which will cause uneven distribution of the developer during subsequent conveying, resulting in excessive developer use in some areas and insufficient developer use in other areas, thereby increasing the overall consumption of the developer and unclear image formation. In addition, when the developer is excessively and unevenly distributed, it will accumulate on some conveying components, increasing the risk of wear and blockage, and further causing equipment failure or shutdown. In addition, uneven developer conveying will result in more waste powder, increasing the difficulty of processing and recycling.

[0004] Secondly, as the supply device operates to supply the developer to the device, the developer interacts with the electrostatic latent image on the photosensitive drum in the developing unit, and the developer is adsorbed to the electrostatic latent image area on the photosensitive drum to form a visible image. During this process, the toner drum transfers the developer to the paper, but not all of the developer will be successfully transferred. The excess developer that fails to be transferred will remain inside the toner drum and eventually accumulate into waste toner. As the waste toner gradually accumulates, the waste toner bin will overflow, which will cause the toner to be unable to be collected normally, thereby affecting the printing quality and causing blur, missing or uneven colors.

[0005] To this end, a developer supply device is proposed. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. As the developer in the powder storage bin is gradually consumed or supplemented, the change in the developer weight during this process will cause the receiving plate to rise and fall in the vertical direction, which can cause the first spring to deform, and the connecting gear can be driven to rotate through the cooperation of the transmission tooth plates on both sides, and then the first eccentric wheel connected to the connecting gear can be synchronously rotated. During the rotation process, the movable seat can be pushed left and right to correspond to the transmission and supply part of the threaded blow molding bottle in the longitudinal direction, and the developer on the receiving plate and the guide plate can be slightly shaken back and forth, so that the developer on the guide plates with staggered circular grooves can be evenly dispersed, corresponding to the transmission and supply area of ​​the threaded blow molding bottle, so that the developer can be evenly distributed in the thread groove of the threaded blow molding bottle, and then the developer is further transmitted to the developing unit, ensuring clear and uniform image formation;

[0018] 2. By setting a powder amount trigger component inside the waste powder bin, as the excess developer that fails to transfer or is scraped off by the blade for cleaning gradually accumulates in the waste powder bin, a second spring with a corresponding stiffness is set in the waste powder bin corresponding to the waste powder warning capacity. When the waste powder is stored in excess, the trigger plate will be pressed downward, and the second eccentric wheels set on both sides of the shaft seat can be rotated under the cooperation of the meshing contact tooth plate and the transmission gear. The second eccentric wheels set opposite to the shaft rods on both sides rotate with the transmission gear through the connecting rod, and the blocking plate can be pushed upward with the assistance of the main crank connecting rod and the auxiliary crank connecting rod on both sides, so as to block the developer powder on the guide plate and suspend the transmission of the developer powder to the threaded blow molding bottle, that is, the source of the developer powder in the printing process is temporarily blocked. In the prior art, the imaging device will issue a warning prompt when the waste powder bin is full. After the waste powder in the bin is manually processed, the trigger plate will move upward accordingly, and then the blocking plate on the other side can be correspondingly recovered downward, so that the developer supply and transmission can continue.

[0019] 3. The developer is fed and delivered by setting a threaded blow-molded bottle, and the developer replenishment process is completed by directly inserting the pipe into the center hole of the inner cover. The inner cover can be adapted to large and small developer pipes, which is more convenient and improves the efficiency of developer replenishment. The head cover is bonded by the internal drive positioning structure of the printer, driving the threaded blow-molded bottle to rotate back and forth 180 degrees, and the periodic reciprocating motion is used to push the developer.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 12, is an embodiment provided by the present invention: 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 head cover 5 is clamped on the front outer wall of the threaded blow-molded bottle 2, an inner cover 6 is arranged inside the head cover 5, a cover 7 is threadedly connected inside the inner cover 6, a soft rubber cover 8 is arranged inside the cover 7, a waste powder bin 3 is fixedly connected to one side of the top of the base 1, a powder storage bin 4 is fixedly connected to the other side of the top of the base 1, a powder uniform transmission anti-air drum assembly for uniformly shaking and distributing the developer is arranged inside the powder storage bin 4, a waste powder overflow source temporary blocking assembly for temporarily blocking the developer when the waste powder overflows is arranged at the bottom of the base 1 and the middle of the waste powder bin 3, wherein:

[0038] The powder-leveling and conveying anti-air drum assembly includes four first guide columns 92, a rectangular cavity 91 is opened in the middle of the powder storage bin 4, the first guide columns 92 on the four sides are respectively fixedly connected to the inner walls of the four corners of the rectangular cavity 91, and the outer walls of the first guide columns 92 on the four sides are sleeved with first springs 93, and the outer walls of the first guide columns 92 on the four sides are slidably connected with a receiving plate 94, and the top of the receiving plate 94 is slidably connected with a guide plate 95, 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 receiving plate 94, and both sides of the bottom of the receiving plate 94 are fixedly connected with a transmission tooth plate 910, and both sides of the inner wall of the rectangular cavity 91 are rotatably connected with a connecting gear 911, and the transmission tooth plate 910 is meshed with the connecting gear 911;

[0039] Wherein: the head cover 5 is set in a lotus tooth groove shape, and the top of the guide plate 95 is provided with two corresponding staggered grooves, which can evenly distribute the developer powder;

[0040] Better: the internal driving locking structure of the imaging device bonds the head cover 5, drives the threaded blow-molded bottle 2 to rotate back and forth 180 degrees in a periodic reciprocating motion to push the developer powder. After a certain amount of developer powder is added to the powder storage bin 4, as the transmission and supply continue, the capacity of the developer powder will gradually decrease, and then the downward pressure on the receiving plate 94 will gradually decrease, so that the squeezing force generated by the receiving plate 94 on each first spring 93 will also be weakened. The first spring 93 can expand upward along each first guide column 92 along with the receiving plate 94. As the receiving plate 94 moves upward, with the cooperation of the transmission tooth plate 910 fixedly connected on both sides, it can drive the corresponding meshing connecting gear 911 to rotate synchronously.

[0041] The middle of the connecting gears 911 on both sides are fixedly connected with the first eccentric wheel 912, the bottom of the guide plate 95 is fixedly connected with the spring plate 96, the middle of the material receiving plate 94 is provided with a square hole 97, the spring plate 96 is slidably connected inside the square hole 97, one end of the spring plate 96 away from the guide plate 95 is fixedly connected with a movable seat 99, 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, the middle of the inner wall of the rectangular cavity 91 is fixedly connected with a stand seat 98, and the movable seat 99 is slidably connected to the middle of the stand seat 98;

[0042] Wherein: the center points of the stand 98, the movable seat 99, the spring plate 96, the material receiving plate 94 and the material guide plate 95 are all located on the same vertical straight line;

[0043] Better: the first eccentric wheels 912 on both sides rotate with the corresponding connecting gears 911 on both sides and the inside of the rectangular cavity 91, and the eccentric shafts on the outer walls of the first eccentric wheels 912 on both sides are all penetrated through the middle of the inner wall of the movable seat 99, and then with the rotation of the first eccentric wheels 912 on both sides, the movable seat 99 can be driven to move back and forth on the longitudinal direction line of the corresponding threaded blow-molded bottle 2, and reciprocate in the middle of the stand 98, so that under the connection and cooperation of the spring plate 96, the guide plate 95 can be driven to reciprocate synchronously on the top of the receiving plate 94, so that the developer powder above the receiving plate 94 can be shaken back and forth to a certain extent to a uniform state, and the positions of the staggered grooves on the guide plate 95 all correspond to the threaded feeding area of ​​the threaded blow-molded bottle 2, so that the developer powder can be evenly conveyed to the thread 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 device, ensuring the clarity of the final image.

[0044] The waste powder overflow powder source temporary blocking component includes a trigger plate 101, which is slidably connected to the middle of the waste powder bin 3, and second guide columns 102 are fixedly connected at the four corners of the bottom of the trigger plate 101. The second guide columns 102 on the four sides are slidably connected to the base 1 and the inside of the waste powder bin 3. Second springs 103 are sleeved on the outer walls of the second guide columns 102 on the four sides, and 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 tooth plate 104 is fixedly connected to the bottom of the release plate 101, a transmission gear 105 is rotatably connected to the inner wall of one side of the bottom of the base 1 close to the waste powder bin 3, the transmission gear 105 is meshedly connected with the contact tooth plate 104, a connecting rod 107 is fixedly connected to the middle of the transmission gear 105, a shaft seat 106 is fixedly connected to the bottom of the base 1, and the middle of both sides of the shaft seat 106 are rotatably connected to the second eccentric wheels 108, and the connecting rod 107 passes through the shaft seat 106 and is fixedly connected to the second eccentric wheels 108 on both sides;

[0045] Wherein: 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 of the outer walls of the second eccentric wheels 108 on both sides are symmetrically arranged on both sides in a stationary state;

[0046] Better: as the waste powder capacity inside the waste powder bin 3 gradually increases, when the waste powder reaches the warning amount, the stiffness of the second spring 103 is not enough to support the waste powder in the waste powder bin 3, and downward pressure will be exerted on the trigger plate 101. Under the guidance of the second guide columns 102 on the four sides, the trigger plate 101 moves downward, and then can move downward synchronously through the contact tooth plate 104, and drive the transmission gear 105 meshing with the contact tooth plate 104 to rotate, and at this time, the second eccentric wheels 108 on both sides can be driven to rotate in the middle of both sides of the shaft seat 106 through the connecting rod 107 with the transmission gear 105, preparing for subsequent adjustment operations.

[0047] Both sides of the bottom of the base 1 are fixedly connected with a first connecting seat 109, and the middle parts of the first connecting seats 109 on both sides are rotatably connected with a main crank connecting rod 1010, and the outer walls of the main crank connecting rods 1010 on both sides away from the first connecting seat 109 are fixedly connected with an elliptical ring piece 1011, and the outer walls of the second eccentric wheels 108 on both sides are slidably connected to the inner walls of the elliptical ring pieces 1011 on both sides, and the bottom of the base 1 is fixedly connected with a second connecting seat 1012 on both sides, and the middle parts of the second connecting seats 1012 on both sides are rotatably connected with a secondary crank connecting rod 1013, wherein one end of the secondary crank connecting rod 1013 on one side away from the second connecting seat 1012 is rotatably connected to the trigger plate 101, and the other end of the secondary crank connecting rod 1013 on the other side away from the second connecting seat 1012 is rotatably connected to a blocking plate 1014, and the blocking plate 1014 is slidably connected to the inside of the base 1 and the powder storage bin 4;

[0048] Wherein: the top of the blocking plate 1014 is flush with the inner wall surface of the powder storage bin 4 in the default state;

[0049] Better: the second eccentric wheels 108 on both sides with the eccentric shafts symmetrically arranged in opposite directions can act on the inner walls of the elliptical ring pieces 1011 on both sides through the eccentric shafts on both sides during the rotation process. As the inclination state of the elliptical ring pieces 1011 in the vertical direction changes, the main crank connecting rod 1010 and the auxiliary crank connecting rod 1013 can be further driven to achieve different degrees of angle opening and closing changes in the vertical direction. Further, with the assistance of the first connecting seat 109 and the second connecting seat 1012 on both sides, the blocking plate 1014 can be driven to move upward and gradually pushed out to the inner wall plane of the powder storage bin 4, thereby temporarily blocking the developer powder inside the powder storage bin 4 to avoid continuous transportation of the powder, thereby causing more waste powder to be generated during the transportation process, causing the waste powder in the waste powder bin 3 to overflow.

[0050] The above implementation works 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 waste powder bin 3 under the support of the second spring 103, and accordingly, the top of the blocking 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 working steps are as follows:

[0054] like Figure 1 - Figure 7 As shown, the internal driving positioning structure of the imaging device is bonded to the head cover 5, driving the threaded blow-molded bottle 2 to rotate back and forth 180 degrees in a periodic reciprocating motion to push the developer powder. After adding a certain amount of developer powder to the powder storage bin 4, as the transmission and supply continue, the capacity of the developer powder will gradually decrease, and then the downward pressure on the receiving plate 94 will gradually decrease, so that the extrusion force generated by the receiving plate 94 on each first spring 93 will also be weakened, and the first spring 93 can slowly expand upward along the first guide columns 92 along with the receiving plate 94. As the receiving plate 94 moves upward, the transmission gear plates 910 fixedly connected on both sides cooperate to drive the corresponding meshing gears 911 to rotate synchronously, and the first eccentric wheels 912 on both sides rotate inside the rectangular cavity 91 along with the correspondingly 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 penetrated and arranged in the middle of the inner wall of the movable seat 99. , and then with the rotation of the first eccentric wheels 912 on both sides, the movable seat 99 can be driven to move back and forth on the longitudinal direction line of the corresponding threaded blow-molded bottle 2, and reciprocate in the middle of the stand 98, so that under the connection and cooperation of the spring plate 96, the guide plate 95 can be driven to synchronously reciprocate on the top of the receiving plate 94, so that the developer powder above the receiving plate 94 can be shaken back and forth to a certain extent to a uniform state, and the positions of the staggered grooves on the guide plate 95 correspond to the thread feeding area of ​​the threaded blow-molded bottle 2, so that the developer powder can be evenly distributed inside each groove, and then the developer powder can be evenly transmitted to the thread 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 device, ensuring the clarity of the final image;

[0055] like Figure 7 - Figure 8As shown, during the process of developer powder being conveyed by the threaded blow molding bottle 2, the scraper in the printer cartridge will evenly scrape the powder on the outer wall of the conveying roller during the boat-laying process, and scrape the excess powder 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 amount, the stiffness of the second spring 103 is not enough to support the waste powder in the waste powder bin 3. The excess waste powder will exert downward pressure on the trigger plate 101 under the action of gravity, and the guides of the second guide posts 102 on the four sides cooperate with each other. Under the condition that the trigger plate 101 moves downward, the trigger plate 101 can 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 shaft seat 106 through the connecting rod 107 connected to the transmission gear 105, so as to prepare for the subsequent adjustment operation. The second eccentric wheels 108 on both sides whose eccentric shafts are symmetrically arranged in opposite directions can act on the inner walls of the elliptical ring pieces 1011 on both sides through the eccentric shafts on both sides during the rotation process.

[0056] like Figure 7 - Fig.12 As shown, as the inclination state of the elliptical ring piece 1011 changes in the vertical direction, the main crank connecting rod 1010 and the auxiliary crank connecting rod 1013 are further driven to realize different degrees of angle opening and closing changes in the vertical direction. The base 1 and the internal corresponding blocking plate 1014 of the powder storage bin 4 are provided with a slideway of corresponding shape. Further, with the assistance of the first connecting seat 109 and the second connecting seat 1012 on both sides, the blocking plate 1014 can be driven to move upward and gradually pushed out to the inner wall plane of the powder storage bin 4, thereby realizing the developer inside the powder storage bin 4. The powder is temporarily blocked to avoid continuous conveying of the powder, which in turn causes more waste powder to be generated during the conveying process, causing 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 avoid leakage. At this time, after the waste powder in the waste powder bin 3 is manually processed, the trigger plate 101 will move upward and return to its original position, and the corresponding blocking plate 1014 in the powder storage bin 4 will also move downward and retract to its original position, so that the powder in the powder storage bin 4 can be further conveyed and supplied.
