Description
Technical Field
The invention relates to the technical field of printing consumables, in particular to a processing box and a driving force transmission assembly thereof.
Background
In image forming apparatuses such as electrophotographic copying machines or digital copying machines and all-in-one printers, a developing device for developing an electrostatic latent image formed on a photosensitive drum is provided, and the developing device applies toner to the electrostatic latent image to develop it. In general, such a developing device is mainly composed of a developing unit including a photosensitive member unit of a photosensitive drum and a developing roller, and toner consumed for development is generally supplied from a toner hopper in the developing unit. In the actual developing process, besides the carbon powder actually needed by developing and printing, a part of waste powder exists, and the waste powder needs to be collected in a waste powder bin in a concentrated manner.
Referring to fig. 1, a conventional color process cartridge 10, which is disposed inside an image forming apparatus 100 by moving along an axial direction of a photosensitive drum 20 to be engaged with the image forming apparatus 100, is mainly characterized in that: the process cartridge 10 is provided with two driving force receiving heads, one provided on the photosensitive drum 20 and the other provided on the developing roller 30. The developing roller drive mainly comprises a plurality of components, and the deviation between the axle center of the drive head and the axle center of the developing roller can be realized through the cross chute coupling structure. The process cartridge 10 is electrically connected to the image forming apparatus 100 by three input voltages of the developing roller 30, the toner discharging blade, and the toner feeding roller, and a force receiving structure position for receiving the urging force of the push rod of the image forming apparatus 100 is provided at the developing hopper position to separate the developing roller 30 from the photosensitive drum 20. In addition, in the process of putting the process cartridge 10 into the image forming apparatus 100, the driving head of the process cartridge 10 is lower than the driving head of the image forming apparatus 100 by the limiting member of the image forming apparatus 100, and when the cover of the image forming apparatus 100 is closed, the limiting member of the image forming apparatus 100 lifts the conductive end of the process cartridge 10 to make the driving head of the process cartridge 10 cooperate with the driving head of the image forming apparatus 100.
In the printing process, the photosensitive drum 20 and waste powder on the machine transfer belt need to be cleaned in time, so that poor printing is prevented. The cleaning process of the existing color process cartridge 10 is: a connecting pin is arranged between the powder bin and the waste powder bin, when a push rod on the imaging device 100 acts on a stressed position on the waste powder box, a developing roller 30 on the powder bin is separated from a photosensitive drum 20 on the waste powder bin, at the moment, a photosensitive drum driving head is driven to rotate by a machine driving force, waste powder of a transfer belt on the imaging device 100 is transferred onto the photosensitive drum 20 in a charging roller charging and discharging process, and then the waste powder on the photosensitive drum 20 is transferred to the waste powder bin by a cleaning scraper. When the photosensitive drum 20 of the process cartridge 10 and the image forming apparatus 100 are automatically cleaned, the hopper of the process cartridge 10 is rotated by a certain angle. Therefore, the structure of the conventional color process cartridge 10 is complicated, and the number of force-receiving positions on the process cartridge 10 is large, and the development roller driving head needs to be constantly kept engaged with the driving head of the image forming apparatus 100, so that the number of parts of the development roller driving head is large.
Referring to fig. 2, there is a conventional method for fixing the driving head 101 to the developing roller 30 in a cross chute structure of the developing roller, but this structure may cause a protrusion 102 of the driving head 101 of the developing roller to be easily stuck at the driving head position of the image forming apparatus 100 when the process cartridge 10 is mounted in the image forming apparatus 100, resulting in that the image forming apparatus 100 cannot normally drive the developing roller 30 to work, thereby affecting printing, and also resulting in that the process cartridge 10 is difficult to be taken out from the image forming apparatus 100.

The developing roller 12 is rotatably supported about its axis between both end walls of the cartridge 11, and one shaft end of the developing roller 12 is provided with a driving force transmission assembly 15, the driving force transmission assembly 15 being for transmitting the rotational force of the developing coupling 103 of the image forming apparatus 100. The driving force transmission assembly 15 and the rotational force transmission mechanism 14 are located on the same end face of the case 11, and the case 11 has an end cap 16 provided on the driving force transmission assembly 15.
Referring to fig. 4 to 9, the driving force transmission assembly 15 includes a driving head assembly 151, a rotational force receiving portion 152, at least two return torsion springs 156, and at least two driving head protrusions 153, the driving head protrusions 153 being hinged to the rotational force receiving portion 152 by pins 155, the number of driving head protrusions 153 of the present embodiment being two or three, and a specific structural description being made with two driving head protrusion 153 embodiments.
The rotational force receiving portion 152 is located at a first end of the driving head assembly 151, and a second end of the driving head assembly 151 may be connected to one axial end of the developing roller 12, specifically, one axial end of an iron shaft of the developing roller.

The driving head protrusion 153 is rotatable about the pin 155 between an axial position substantially parallel to the rotational force receiving portion 152 and an axial position facing the rotational force receiving portion 152, and the rotational force receiving portion 152 is provided with a stopper 157 that restricts rotation of the driving head protrusion 153 toward the axial position of the rotational force receiving portion 152. The coils of the return torsion spring 156 are sleeved on the pin 155, the first torsion arm of the return torsion spring 156 abuts against the rotational force receiving portion 152, and the second torsion arm of the return torsion spring 156 abuts against the driving head protrusion 153. The two adjacent driving head protrusions 153 are located in a semicircular surface of the end surface of the rotational force receiving portion 152, in this embodiment, the semicircular surface is a surface formed by sweeping 180 degrees around the center of a circle with a radius, and in this embodiment, a central angle corresponding to an arc formed between the two adjacent driving head protrusions 153 is 120 degrees.
