Description

Technical Field

[0001] This utility model relates to the technical field of developing cartridges, and in particular to a developing cartridge with a drive head guide plate. Background Technology

[0002] The driver heads of commercially available developing cartridges are retractable, which allows for easy adjustment when the driver head receives driving force. However, this can be inconvenient when engaging and disengaging from the driver head, and can easily cause wear and damage to the driver head, thus affecting the normal printing operation of the developing cartridge. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a developing cartridge with a drive head guide plate, which can prevent damage to the drive head when the drive head is docked or detached from the drive component of the image imaging device.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a box body, and an end cap is provided at the end of the box body. A driving head and a guide plate are provided on the end cap. The driving head and the guide plate are rotatably connected to the end cap. A first guide slope is provided on the guide plate. The first guide slope can abut against the driving component of the image imaging device. When the guide plate rotates, the first guide slope can approach the driving head. When the driving head approaches the first guide slope, it can dock with the driving component of the image imaging device to receive driving force.

[0005] Furthermore, the end of the driving head has two driving blocks arranged opposite each other, and the driving head is driven by the driving components of the image imaging device through the two driving blocks.

[0006] Furthermore, each of the two drive blocks is provided with a second guide ramp, and the drive component of the image imaging device can be disengaged from the drive head along the second guide ramp.

[0007] Furthermore, the center of the end of the driving head has a docking hole adapted to the driving component of the image imaging device, and the end of the driving head has two oppositely arranged docking grooves, both of which are adapted to the driving component of the image imaging device and are respectively located on one side of the two driving blocks.

[0008] Furthermore, the end of the guide plate can abut against the drive head when the first guide ramp is close to the drive head.

[0009] Furthermore, the cross-section of the guide plate is a rounded cone shape.

[0010] Furthermore, the rotation axis of the drive head is parallel to the length direction of the box body, and the rotation axis of the guide plate is perpendicular to the rotation axis of the drive head.

[0011] Furthermore, the end cap is provided with a mounting base, the mounting base has two mounting holes, and both sides of the guide plate are provided with protrusions, the two protrusions being rotatably connected to the two mounting holes respectively.

[0012] The beneficial effects of this utility model are: In contrast to the shortcomings of existing technologies, this invention guides the driving component of the image imaging device through a rotating guide plate, and further drives the driving component to connect to the driving head along the first guide slope. This avoids the driving component directly connecting to the driving head, which would cause the driving head to wear easily. Therefore, this invention can prevent damage to the driving head when it connects or disconnects from the driving component, thus extending its service life. Moreover, it has a simple structure and reduces costs, giving it the advantage of preventing damage to the driving head. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a housing 1, with an end cap 2 at one end of the housing 1. A drive head 3 and a guide plate 4 are mounted on the end cap 2. Both the drive head 3 and the guide plate 4 are rotatably connected to the end cap 2. A first guide slope 5 is provided on the guide plate 4. The first guide slope 5 can abut against the drive assembly 6 of the image imaging device. When the guide plate 4 rotates, the first guide slope 5 can approach the drive head 3. When the first guide slope 5 approaches the drive head 3, the drive head 3 can engage with the drive assembly 6 of the image imaging device to receive driving force. The rotation axis of the drive head 3 is parallel to the length direction of the housing 1, and the drive head 3 is a non-retractable structure, while the drive assembly 6 of the image imaging device is a retractable structure.

[0021] When the driving head 3 of the developing cartridge needs to receive the driving force of the driving component 6 of the image imaging device, the driving component 6 first abuts against the first guide slope 5 of the guide plate 4. The guide plate 4 then rotates under the push of the driving component 6. At this time, the driving component 6 moves closer to the driving head 3 along the first guide slope 5. When the driving component 6 moves to the far end of the guide plate 4 along the first guide slope 5, the driving component 6 can move and dock with the driving head 3, so that the driving head 3 can receive the driving force of the driving component 6.

[0022] In contrast to the shortcomings of existing technologies, in this invention, the driving component 6 of the image imaging device is guided by a rotating guide plate 4, and the driving component 6 is further driven to mate with the driving head 3 along the first guide slope 5. This provides a smooth and controlled movement path for the driving component 6, enabling it to be accurately aligned and finally engage with the driving head 3. This avoids the situation where the driving head 3 is easily worn due to direct docking between the driving component 6 and the driving component 6. Therefore, this invention can prevent damage to the driving head when the driving head 3 is docked or disengaged from the driving component 6, thus extending its service life. Moreover, the structure is simple and the cost is reduced, giving this invention the advantage of being able to avoid damage to the driving head.

[0023] like Figure 3 As shown, in some embodiments, the end of the driving head 3 has two driving blocks 7 arranged opposite each other. The driving head 3 is driven by the two driving blocks 7 to drive the driving component 6 of the image imaging device. Each of the two driving blocks 7 is provided with a second guide slope 8, and the driving component 6 of the image imaging device can disengage from the driving head 3 along the second guide slope 8. When driven, the driving component 6 of the image imaging device rotates to drive the two driving blocks 7 to rotate, thereby achieving transmission of the driving head 3. Specifically, when the driving component 6 disengages from the driving head 3, the driving component 6 can disengage from the driving head 3 along the second guide slope 8, making it easy for the driving component 6 of the image imaging device to disengage, further preventing wear on the driving head 3.

[0024] like Figure 3As shown, in some embodiments, the center of the end of the driving head 3 has a docking hole 9 adapted to the driving component 6 of the image imaging device, and the end of the driving head 3 has two oppositely arranged docking grooves 10. Both docking grooves 10 are adapted to the driving component 6 of the image imaging device and are respectively located on one side of the two driving blocks 7. The driving component 6 specifically includes a driving column, with push columns on both sides of the driving column. During driving, the driving column and push columns rotate together, thereby driving the two driving blocks 7 to rotate through the two push columns, thus realizing the transmission of the driving head 3. Specifically, the driving column of the driving component 6 is aligned with the docking hole 9 during driving, and the two push columns of the driving component 6 are respectively located in the two docking grooves 10. Therefore, the arrangement of the docking hole 9 and the two docking grooves 10 facilitates the docking of the driving component 6 with the driving head 3 and ensures that the driving component 6 is not easily detached from the driving head 3 after docking.

[0025] like Figure 4 and Figure 5 As shown, in some embodiments, the end of the guide plate 4 can abut against the drive head 3 when the first guide slope 5 is close to the drive head 3; the cross-section of the guide plate 4 is a rounded cone shape; the rotation axis of the drive head 3 is parallel to the length direction of the box body 1, and the rotation axis of the guide plate 4 is perpendicular to the rotation axis of the drive head 3; a mounting base 11 is provided on the end cover 2, and two mounting holes 12 are opened on the mounting base 11; protrusions 13 are provided on both sides of the guide plate 4, and the two protrusions 13 are rotatably connected in the two mounting holes 12 respectively. Specifically, the guide plate 4 can rotate within a certain angle around its own axis of rotation (i.e., the line connecting the two protrusions 13) through the cooperation of the protrusions 13 on it and the mounting holes 12 on the end cap 2; secondly, the end of the guide plate 4 abuts against the drive head 3 when the first guide slope 5 is close to the drive head 3, so that the drive component 6 of the image imaging device can be easily connected from the first guide slope 5 to the drive head 3, so as to avoid the drive component 6 falling into the space between the end of the guide plate 4 and the drive head 3 and being unable to connect.

[0026] Preferably, an elastic element, which may be a torsion spring, may be provided on the mounting base 11 or the guide plate 4. This elastic element can apply a preload to the guide plate 4, so that it remains in its initial position in its natural state. This initial position facilitates the initial contact of the drive assembly 6. When the drive assembly 6 disengages, the guide plate 4 can automatically reset under the action of the elastic element, preparing for the next drive force.

[0027] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
