Description

Powder adding box

Technical Field

The present invention relates to a charging cartridge for replenishing developer to an image forming apparatus.

Background

After the printing consumables are consumed, the developing box (the box with the developing roller and other parts) or the ink box needs to be directly replaced by the imaging equipment such as the laser printer, the copying machine and the like, so that the old developing box and the old ink box are directly scrapped and cannot be reused, and the resource waste is caused. Therefore, an external toner cartridge capable of replenishing toner (a type of developer) to a developing cartridge in an image forming apparatus has been developed, and the toner can be directly injected into the developing cartridge of the printer through a communication port provided in the printer. After the carbon powder of the developing box in the printer is used up, the developing box does not need to be replaced, and only the powder is added into the developing box through the powder adding box, so that the developing box can be repeatedly used.

The existing powder adding box has the advantages that when the powder adding operation is carried out, a user needs to manually press a piston rod for pushing carbon powder to add the powder, and the user is inconvenient in use and useless.

Of course, the receiving groove may be eliminated as long as the space between the pushing member and the main body is sufficient to give way to the second arm portion.

As shown in fig. 35 to 38, as a modification of the eighth embodiment, the limiting device 101 of the present embodiment includes an elastic arm 1013 and a limiting part 1014, wherein an inner wall of an upper end of the main body 1 of the powder adding box 100 is provided with a mounting groove 110 for mounting the elastic arm 1013, the mounting groove 110 may be a circular groove, the elastic arm 1013 has a cylindrical shape, an outer diameter of the elastic arm 1013 is the same as or slightly smaller than an inner diameter of the mounting groove 110, the elastic arm 1013 itself has elasticity and can deform when receiving an external force, one end of the elastic arm 1013 is fixedly mounted in the mounting groove 110, and the other end of the elastic arm 1013 protrudes out of the inner wall of the main body 1; the limiting portion 1014 is disposed on the sidewall of the lower end of the first rod portion 21, the limiting portion 1014 may be a protruding portion, in the initial position, one end of the elastic arm 1013 protruding from the inner wall of the main body 1 abuts against the limiting portion 1014, and specifically, one end of the elastic arm 1013 protruding from the inner wall of the main body 1 is located below the limiting portion 1014 to abut against the limiting portion 1014, so as to form a resistance force to the pushing member 2, so as to limit the pushing member 2 from moving in the longitudinal direction of the main body 1.

The pushing member 2 may be maintained at the initial position or may be automatically restored to the initial position when the pushing member 2 is collided with by the outside by the stopper 101 located at both sides of the first lever part 21.

As shown in fig. 37, when the powder adding operation is performed, the user can directly push the pressing portion 22 of the pushing member 2 to generate a pushing force acting on the pushing member 2 in the pushing direction P of the pushing member 2, the pushing member 2 moves in the pushing direction P against the resistance between the elastic arm 1013 and the limiting portion 1014 under the action of the pushing force, at this time, the elastic arm 1013 starts to deform, the pushing member 2 continues to move as the pushing force further increases, the degree of deformation of the elastic arm 1013 increases, and when the force in the pushing direction P of the pushing member 2 reaches a predetermined threshold value (i.e., reaches a certain force), the elastic arm 1013 deforms to completely pass over the limiting portion 1014, at this time, the limiting device 101 releases the limitation on the pushing member 2, the pushing member 2 moves in the pushing direction P, and the carbon powder in the main body 1 is gradually discharged from the powder outlet. As shown in fig. 38, after the stopper device 101 releases the restriction on the pushing member 2, that is, after the stopper 1014 has passed over the elastic arm 1013, the resistance of the elastic arm 1013 to the stopper 1014 is lost, the pushing member 2 is relatively easily moved, and the elastic arm 1013 is deformed and restored after the stopper 1014 has passed over.

Alternatively, the resilient arm 1013 may have other shapes, such as flat, prism, etc., and the shape is not limited as long as it can function to define the position of the pushing member 2, and the shape of the corresponding mounting groove 110 may correspond to the shape of the resilient arm 1013.

When the movable member D3 is moved in the longitudinal direction Z of the first developer accommodating chamber D11 in a direction approaching the developer outlet D121 (i.e., in a process of moving from the first position to the second position), the toner accommodated in the first developer accommodating chamber D11 is discharged from the developer outlet D121 by the urging of the movable member D3, and when the movable member D3 moves to the second position, the bottom of the piston portion D33 can abut on the top of the second restriction position D112, thereby defining the moving range of the movable member D3, and the movable member D3 cannot move downward any more.

The second developer accommodating chamber D2 is provided outside the main body D1, the second developer accommodating chamber D2 is a substantially rectangular box-like structure, a first passage D6 is provided between the second developer accommodating chamber D2 and the first developer accommodating chamber D11, and the second developer accommodating chamber D2 and the first developer accommodating chamber D11 are communicated by the first passage D6.

Alternatively, a communication port of the second developer accommodating chamber D2 with the first passage D6 is provided on a side wall of the second developer accommodating chamber D2 toward the main body D1 direction; it is also possible to omit the first passage D6, attach the side wall of the second developer accommodating chamber D2 to the side wall of the main body D1, and provide a passage port at the attachment point to communicate the second developer accommodating chamber D2 with the first developer accommodating chamber D11.

As shown in fig. 66 and 67, first check valve member D4 is disposed in first passage D6, first check valve member D4 allows toner to flow only in one direction, and is sealed in the other direction, in this embodiment, first check valve member D4 is disposed to allow toner to flow only from second developer accommodating chamber D2 to first developer accommodating chamber D11, and first developer accommodating chamber D11 is sealed in the direction of second developer accommodating chamber D2, that is, toner in first developer accommodating chamber D11 cannot flow to second developer accommodating chamber D2. The first check valve member D4 is made of a flexible material, preferably an elastic material such as a silicon film. The first check valve member D4 has a conical shape in which a plurality of slits D41 are arranged at equal angular intervals with the center thereof being the intersection point, the end of the conical first check valve member D4 having a small diameter faces the first developer accommodating chamber D11, and the end of the conical first check valve member D4 having a large diameter faces the second developer accommodating chamber D2, and the plurality of slits D41 of the first check valve member D4 can be opened by the air pressure in one direction (flowing from the second developer accommodating chamber D2 to the first developer accommodating chamber D11), and can be closed in the other direction. The air pressure flowing from the second developer accommodating chamber D2 to the first developer accommodating chamber D11 may be generated by the movement of the movable member D3, when the movable member D3 is in the second position, the amount of gas in the first developer accommodating chamber D11 is small, and when the movable member D3 is pulled to move from the second position to the first position (i.e., the movable member D3 moves upward), the volume of the space in which the gas in the first developer accommodating chamber D11 is located becomes large, the gas pressure in the first developer accommodating chamber D11 becomes low, the gas pressure in the second developer accommodating chamber D2 is higher than the gas pressure in the first developer accommodating chamber D11, the gas in the second developer accommodating chamber D2 flows toward the first developer accommodating chamber D11, and the first check valve member D4 is pushed to open, the developer in the second developer accommodating chamber D2 is sucked into the first developer accommodating chamber D11 due to the difference in air pressure between the second developer accommodating chamber D2 and the first developer accommodating chamber D11. First check valve member D4 is further provided with a mounting portion D42 at its larger diameter end, and specifically, mounting portion D42 may be a flange extending in a direction away from the center of first check valve member D4, and first check valve member D4 may be fixed in first duct D6 by this flange, or may be fixed by welding, adhesion, engagement, or the like.

Alternatively, the first check valve member D4 may have a circular truncated cone shape, a hemispherical shape, a pyramid shape, a truncated pyramid shape, or other geometric shape, and the shape is not limited as long as the effect of causing the developer in the second developer accommodating chamber to flow in one direction to the first developer accommodating chamber D11 is achieved.

Alternatively, the first check valve member D4 may be provided inside the second developer accommodating chamber D2, specifically, at a communication port of the second developer accommodating chamber D2 and the first developer accommodating chamber D11.

And a second check valve member D5 disposed in the second passage D7, wherein the second check valve member D5 allows only the toner to flow in one direction, and is sealed in the other direction, and in this embodiment, the second check valve member D5 allows only the toner to flow from the first developer accommodating chamber D11 to the developer outlet D121, and the developer outlet D121 is sealed in the direction toward the first developer accommodating chamber D11. The second check valve member D5 is similar in structure and principle to the first check valve member D4 in that the second check valve member D5 has a large diameter end facing the first developer accommodating chamber D11 and a small diameter end facing the developer outlet D121, and when the movable member D3 moves downward (i.e., during movement from the first position to the second position), the toner accommodated in the first developer accommodating chamber D11 pushes the upper slits of the second check valve member D5 open by the urging of the movable member D3 and is discharged from the developer outlet D121.

Alternatively, the second passage D7 may not be provided, and the second check valve member D5 may be directly fixed to the side wall of the first developer accommodating chamber D11.

The movable member D3 is movable between a first position and a second position, and when the toner needs to be replenished, the movable member D3 is pulled to move from the second position to the first position, the first check valve member D4 is opened, the toner in the second developer accommodating chamber D2 enters the first developer accommodating chamber D11 via the first check valve member D4, and the communication passage is blocked by the third seal D51 of the second check valve member D5. When the movable member D3 is pushed to move from the first position to the second position, the first check valve member D4 is closed, the second check valve member D5 is opened, and the toner reaches the developer outlet D121 from the first developer accommodating chamber D11 and enters the developer cartridge, thereby completing the toner charging operation.

In this embodiment, the volume of the first developer accommodating chamber D11 may be greater than the volume of the second developer accommodating chamber D2, or may be smaller than the volume of the second developer accommodating chamber D2.

Alternatively, the first developer accommodating chamber D11 may be used as a quantitative filling value per time, for example, if the volume of the first developer accommodating chamber D11 is set to 100g, and the volume of the second developer accommodating chamber D2 is 1000g, if the movable member D3 is pulled upward once (from the second position to the first position) to suck 100g of toner from the second developer accommodating chamber D2 into the first developer accommodating chamber D11, and when the movable member D3 is pushed downward (from the first position to the second position), 100g of toner in the first developer accommodating chamber D11 may be pushed into the developing cartridge, and the movable member D3 is pulled and pushed back and forth to fill 100g of toner into the developing cartridge; when 500g of toner needs to be replenished, 5 back-and-forth motions are required, and if only 50g of toner can be sucked in one back-and-forth motion of the movable component D3, 10 back-and-forth motions are required, and the like.

Alternatively, the second developer accommodating chamber D2 may be used as a quantitative filling value for each time, for example, the volume of the second developer accommodating chamber D2 is set to 100g, the developer in the second developer accommodating chamber D2 may be completely extracted by one back and forth movement of the movable member D3, and when 200g needs to be replenished, the toner may be replenished to the second developer accommodating chamber D2 first, and then the toner may be replenished, and so on.

Alternatively, the amount of toner sucked into the first developer accommodating chamber D11 may be controlled by the amount of movement of the movable member D3 to control the amount of toner added to the developing cartridge in each round trip, and when the toner is added to the developing cartridge by a predetermined amount, the image forming apparatus may perform a signal prompt, at which time the toner addition may be stopped.

According to the powder adding box 100, due to the arrangement of the quantitative filling mechanism, quantitative filling can be performed for one time or multiple times through the quantitative filling mechanism according to the developing boxes with different capacities, so that the technical problem of the existing powder adding box 100 can be solved. In addition, the existing powder adding box 100 comprises a main body D1 for containing a developer and a piston rod, when adding carbon powder to the developing box, the powder adding box 100 is inserted into a communication port on a printer, and the piston rod is pushed to add all the carbon powder in the powder adding box 100 into the developing box, but because the carbon powder and the gas in the powder adding box 100 are quickly pressed into the developing box at one time during the powder adding operation, a large amount of carbon powder and gas enter the developing box, which easily causes the accumulation of a large amount of carbon powder at the communication port of the developing box, causes blockage, and is not beneficial to the transportation of the carbon powder inside the developing box; meanwhile, the air pressure in the developing box can be quickly increased, and larger air pressure can be applied to the ventilating part (such as a ventilating film) of the developing box, so that the ventilating part (such as the ventilating film) is damaged.

When the movable member D3 moves downward (i.e., during movement from the first position to the second position), the toner contained in the first developer accommodating chamber D11 pushes the third seal D51 downward by the urging force of the movable member D32, and the elastic restoring member D52 is compressed downward, so that the third seal D51 and the elastic restoring member D52 move downward, the third seal D51 disengages from the passage port of the second passage D7 toward the first developer accommodating chamber D11 side, and the toner can enter the second passage D7 and is discharged out of the body D1 through the developer outlet D121. After the toner in the first developer accommodating chamber D11 is pushed, the elastic restoring member D52 elastically deforms and restores, pushing the third sealing member D51 upward to restore to the initial position where the second passage D7 seals the passage opening on the side of the first developer accommodating chamber D11. Preferably, the elastic restoring member D52 is a compression spring, and alternatively, the elastic restoring member D52 may be a tension spring, a spring plate, an elastic rubber, an elastic sponge, or the like.

Optionally, at least one powder inlet D511 is disposed on a side wall of the third sealing member D51, and the carbon powder can enter the cavity of the third sealing member D51 through the powder inlet D511 after entering the second channel D7, and then enter the developer outlet D121 from the lower end opening of the third sealing member D51.

Alternatively, the third seal D51 may also be a rectangular parallelepiped, prismatic, or the like shaped member.

Alternatively, first check valve member D4 is similar in structure and principle to second check valve member D5 described above in that first check valve member D4 is disposed in first passage D6, the end of third seal D51 remote from the opening is directed toward second developer accommodating chamber D2, and elastic restoring member D52 is directed toward first developer accommodating chamber D11.

A passage communicating between the first developer accommodating chamber D11 and the third developer accommodating chamber D13 is a second passage D7, and a second check valve member D5 is provided in the second passage D7, so that the toner in the first developer accommodating chamber D11 is unidirectionally transported to the third developer accommodating chamber D13.

Alternatively, the screw structure may not be provided at the outlet, for example, may be provided offset from the outlet, but may dredge the developer near the outlet of the developer supply passage, and since the developer has a certain fluidity, in the case where the developer near the outlet of the developer supply passage is dredged, the developer at the outlet of the developer supply passage flows, so that the developer accumulated at the outlet of the developer supply passage is dredged.

In this embodiment, two developer supply channels E7 connected between the developing part E1 and the developer container E6 are provided, the two developer supply channels E7 are respectively located at both ends of the stirring member E171, the screw structures E172 at both ends of the stirring member E171 are respectively arranged below the outlets of the two developer supply channels E7, when both ends of the rotation shaft in the length direction are provided with the screw structures E172, the stirring blade E173 is arranged between the first screw structures E172 at both ends, when the conveying member E17 conveys the developer to the developing roller E13 of the developing part E1, the screw segments of the screw structures E172 at both ends of the rotation shaft in the length direction are all used for conveying the developer to the direction close to the stirring blade E173, so that the screw structures E172 at both ends of the stirring member E171 feed the toner from the outlets of the developer supply channels to the middle of the two developer supply channels, thereby avoiding the accumulation of the toner at the outlets of the developer supply channels E7, avoiding blockage.

Waste developer container E5 is located on the upper side of developing section E1, waste developer container E5 is spaced upward from developing section E1, and optical path D is formed between waste developer container E5 and developing section E1.

Also, the recess E8 in which the waste developer container E5 accommodates the optical scanner located at the rear of the developing section E1 may be defined by the developing section E1 having a length shorter than that of the waste developer container E5 and the waste developer container E5 located at the upper side of the developing section E1. For example, the waste developer container E5 may include a first portion E53 and a second portion E54 which are sequentially disposed from the vicinity of the photosensitive drum E11, and the first portion E53 may be disposed in the vicinity of the photosensitive drum E11 and mainly contain the waste developer. The second portion E54 corresponds to the recess E8 and may be positioned to step upward than the first portion E53, and the second portion E54 connects the first portion E53, and thus, the second portion E54 has a shape inclined upward from the first portion E53 toward the second portion E54, and the waste developer container E5 may further include a third portion E55 located behind the recess E8, extending downward from the second portion E54, by which the waste developer container E5 may obtain a larger space for containing the waste toner.

For example, the hopper section E62 may be located above the third section E55 of the waste-developer container E5. The lower wall of hopper section E62 may be partially embedded downward in third section E55 and hopper section E62 may be formed in a complementary shape to the upper wall and project downward, by doing so, a greater capacity of hopper section E62 may be achieved. A conveying member E63 may be further provided in the developer container E6, the conveying member E63 may convey the developer to the developer supply passage E7, and the developer may be conveyed to the developing portion E1 through the developer supply passage E7.

In the developer conveying process, because the conveying member E17 rotates in the developing part E1, the conveying member E17 can convey the developer to the direction of the outlet far away from the developer supply channel E7 and the rotating direction of the conveying member E17 along the length direction of the conveying member E17, the situation that the developer at the outlet of the developer supply channel E7 cannot be conveyed in time to cause the stacking box to block the developer supply channel E7 is avoided, meanwhile, the powder can be fed to the developing part E1, the carbon powder is conveyed more quickly, the situation that a large amount of carbon powder is stacked at the outlet of the developer supply channel E7 is avoided, and blocking is avoided.

In the present embodiment, the screw thread of the first screw E174 is arranged along the length direction of the first screw E174, the screw thread of the first screw E174 is located at the outlet of the developer supply passage E7, and the first screw E174 can be rotated by receiving the driving force from the driving force receiving member of the developing cartridge. When the first screw E174 rotates, the flight of the first screw E174 rotates in the direction of rotation of the first screw E174, and when the developer falls on the flight, the developer is transferred on the flight of the first screw E174, so that the first screw E174 can transfer the developer in the longitudinal direction thereof, and because of the rotation of the first screw E174, a part of the developer falling on the first screw E174 is also transferred in the direction of the supply roller E15 and the developing roller E13. The first screw E174 is provided with two threads, the directions of the two threads are opposite, the two threads of the first screw E174 are respectively located at the outlets of the two developer supply passages E7 of the developing cartridge, and the directions of the two threads are opposite, so that the developer at the outlet of the developer supply passage E7 is transported on the first screw E174 along the direction of the middle position of the first screw. In some other embodiments, two first screws E174 are provided in the same axial direction, and the thread directions of the two first screws E174 are opposite to each other, the first screws E174 can be provided at the outlet of the developer supply passage E7, so that the developer below the developer supply passage E7 can be relatively transferred along the threads on the first screws E174, the developer at the outlet of the developer supply passage E7 can be transferred by the first screws E174, and the first screws E174 can transfer the developer at the developer supply passage E7 along the axial direction of the rotating shaft to a direction close to the middle position of the rotating shaft in the transfer along the length direction of the conveying member E17, so that a large amount of toner can be prevented from accumulating at the outlet of the developer supply passage E7, and clogging can be avoided; further, since the first screw E174 transfers the developer at the outlet of the developer supply passage E7 in the axial direction of the rotary shaft toward a direction close to the middle position of the rotary shaft, the distribution of the developer in the length direction of the first screw E174 is made more uniform.

As shown in fig. 78, as another modification of embodiment fifteen, there is provided another developing cartridge, which is different from embodiment fifteen in that: in the present embodiment, a toner detection device E9 is provided between the two developer supply paths E7. When the developer supply path E7 is clogged or the fluidity of toner is poor, the developer cannot flow from the outlet of the developer supply path E7 to the position detected by the toner detection device E9, and the printer displays a toner shortage signal. In the present embodiment, the conveying member E17 is provided near the toner detection device, so that the conveying member E17 can deliver the developer to the vicinity of the toner detection device E9, and inaccurate detection by the toner detection device E9 is avoided, which affects printing.
