Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of image forming, and in particular to a cleaning device, an image forming device, a control method and a readable storage medium. BACKGROUND

[0002] An image forming device is a device for forming an image on a print medium according to an input signal. For example, a printer, a copier, a fax machine, and a multifunction printer integrating the functions of a printer, a copier, and a fax machine can be applied to the image forming device.

[0003] Taking a color printer as an example, an ACR-SENSOR (color density correction sensor, also known as a CTD-SENSOR, ACR sensor or CTD sensor) is an important optical component of the printer. The ACR-SENSOR emits light on a color block, receives the reflected light, judges the color density, and thus guarantees the image quality. Such optical components are very sensitive to light. A cover glass or transparent plastic cover is used to protect the internal optical components from contamination by toner or paper powder. However, the surface of the ACR-SENSOR may be contaminated by toner or paper powder after long-term printing, affecting the emission or reception of light, and thus affecting the image quality.

[0004] The ACR-SENSOR cleaning mechanism in the prior art is generally linked with the outer cover of the machine or a separate motor-driven cleaning mechanism is provided to clean the ACR-SENSOR. However, the linkage with the outer cover needs to be manually operated by the user, which may cause unnecessary contamination and poor user experience. The separate motor-driven cleaning mechanism needs to occupy a large space and increase the cost.

[0005] To solve the above problems, the present application provides a sensor cleaning mechanism. The driving of the roller is linked with the driving of the cleaning mechanism and the driving of the stirring mechanism in the toner container through a one-way gear set or a clutch, so as to be driven by the same power source. The cleaning mechanism of the sensor is moved and the stirring mechanism of the toner container is rotated by the forward and reverse rotation of the roller. SUMMARY

[0006] The present application provides a cleaning device, an image forming device, a control method and a readable storage medium, which aims to clean the detection element and prevent the detection element from being contaminated by toner or paper powder, thereby affecting the printing effect.

In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0131] It should be noted that the "up", "down", "left", "right" and other orientation words described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as a limitation of the embodiments of the present application.

[0132] As shown in Figure 1 and 2 The present embodiment provides an image forming apparatus 1, which can be a printer, a copier, a fax machine, and a multifunction printer integrating the functions of a printer, a copier and a fax machine. The image forming apparatus 1 includes an apparatus main body 10, a sheet supply cassette 20, a conveying assembly 30, a transfer unit 40, a laser unit 50, a detection unit 60, a fixing unit 70, and a toner container 80.

[0133] When the image forming apparatus 1 is in operation, the sheets stacked in the sheet supply cassette 20 are separated one by one and conveyed to the transfer unit 40 by the conveying assembly 30. The laser unit 50 converts the received image information into a light beam and irradiates the photosensitive drum 41 in the transfer unit 40 to form an electrostatic latent image. The electrostatic principle allows the carbon powder to adhere to the electrostatic latent image area on the photosensitive drum 41 to generate a carbon powder image. The carbon powder image is transferred to the transfer belt 43 by the transfer roller 42, and the transfer belt 43 conveys the carbon powder image to the secondary transfer unit 44. The secondary transfer unit 44 further transfers the carbon powder image to the sheet, and the sheet with the carbon powder image is further conveyed to the fixing unit 70. After the heating roller 71 and the pressure roller 72 in the fixing unit firmly fix the carbon powder image on the sheet, the sheet can be discharged.

[0134] The photosensitive drum 41 includes YMCK photosensitive drums respectively corresponding to four different colors (yellow, magenta, cyan, and black), and the four different color toner cartridges 45 are provided.

[0135] When the image forming apparatus 1 is affected by various factors, such as the temperature and humidity in the environment or inside the device body 10, the service life of the components, and vibration of the device body 10, the image quality of the image forming apparatus 1 when performing imaging can be affected, causing changes in the color density of the image or color deviation, and the like. Therefore, a detection element 62, such as a color density correction sensor, is provided to help adjust the imaging conditions to improve the image quality. However, during the above imaging process, toner can be scattered inside the device body 10 for various reasons, and can fall onto the working surface 621 of the detection element 62, causing contamination and affecting the accuracy of the detection. Therefore, a cleaning device 100 is provided to protect and clean the working surface 621 of the detection element 62.

[0136] As shown in FIG. 1, the cleaning device 100 includes a controller 11, a conveying unit 30, and a detection unit 60. Figures 2 to 4

[0137] Specifically, the cleaning device 100 includes a mounting seat 61 fixed to the support panel 68 for mounting the detection device, the detection device including two detection elements 62, a connecting member including a push handle 65 that can slide in the sliding groove 66 and a connecting rod 63 that can slide on the mounting seat 61, a cleaning member 633 attached to the connecting rod 63 for cleaning the detection element 62, a driving member including a driving source 12 and a correction roller 31, which can transmit the driving force of the driving source 12 to the linkage member through the correction roller 31 to provide driving force for the cleaning device 100, and a linkage member connected to the connecting member and the driving member. The linkage member further includes a one-way transmission member, which can be composed of a one-way gear set (including a driving gear 35, an intermediate gear 36, and a driven gear 37) and a cam gear 67, which can receive the driving force from the driving source 12 and push the push handle 65 and the connecting rod 63. The cam gear 67 has an inclined edge 671 on the end face that abuts against the push handle 65, and the mounting seat 61 has a resilient member 64 connected to the mounting seat 61 and the connecting rod 63 at both ends. Therefore, the cam gear 67 can push the connecting rod 63 and the push handle 65 to move back and forth, so that the cleaning member 633 can be exposed, hidden, and clean the working surface 621 of the detection element 62.

[0138] ​Specifically, the detection unit 60 is arranged below the transfer belt 43, and the detection unit 60 comprises a mounting base 61, a detection element 62, a connecting rod 63, an elastic member 64, a pushing handle 65, a sliding groove 66, a cam gear 67, and a support plate 68. The detection unit 60 can be used to detect the image information on the transfer belt 43, and adjust the imaging conditions according to the read information to improve the image quality.

[0139] The mounting base 61 is connected to the equipment main body 10 after being mounted to the support plate 68, the detection element 62 is mounted in the mounting base 61, and a notch 611 is formed on the upper surface of the mounting base 61 to expose the working surface 621 of the detection element 62; the upper surface of the mounting base 61 is further provided with a sliding groove 612 which can cooperate with the buckle 632 of the connecting rod 63 and enable the connecting rod 63 to make horizontal reciprocating motion on the sliding groove 612, and a window 631 is formed on the connecting rod 63 which can correspond to the position of the working surface 621 of the detection element 62, so that the connecting rod 63 can shield or expose the working surface 621 of the detection element 62, and when the working surface 621 of the detection element 62 is exposed, the image information on the transfer belt 43 can be read.

[0140] As shown in Figures 5 to 9 The cleaning member 633 is arranged on the connecting rod 63, which can be a cleaning sponge, a cleaning brush, etc., and is attached to the inner surface of the connecting rod 63 and adjacent to the position of the window 631. The elastic member 64, such as a tension spring, is arranged, one end of which is connected to the mounting base and the other end of which is connected to the connecting rod 63, when the connecting rod 63 is pushed to the first position by an external force greater than the elastic member, the working surface 621 of the detection element 62 is exposed from the window 631, and the detection element 62 can read the image information on the transfer belt 43; when the connecting rod 63 is not pushed by the external force, the connecting rod 63 slides to the second position, the detection element 62 is shielded, and the cleaning member 633 passes through the working surface 621 of the detection element 62 to clean the working surface 621 of the detection element 62.

[0141] In order to make the connecting rod 63 more convenient to install, the pushing handle 65 and the sliding groove 66 are arranged to reduce the possibility of deformation of the connecting rod 63 due to collision during installation. The sliding groove 66 is fixed to the equipment main body 10, and the pushing handle 65 is arranged to slide in the sliding groove 66, and the first end 651 of the pushing handle 65 towards the connecting rod 63 is provided with an inclined surface matched with the connecting rod 63 to provide a certain pressure to stabilize the connection between the connecting rod 63 and the pushing handle 65.

[0142] The second end 652 of the push handle 65 abuts against the cam gear 67, which is provided with an inclined edge 671 on the end face on the side facing the connecting rod 63. When the cam gear 67 rotates, the second end 652 of the push handle 65 can slide along the inclined edge 671. Under the joint action of the inclined edge 671 and the elastic member 64, the connecting rod 63 and the push handle 65 can move horizontally reciprocating above the mounting base 61, so as to switch the connecting rod between the first position and the second position, and expose or shield the working surface 621 of the detection element 62.

[0143] The cam gear 67 receives the driving force from the conveying unit 30, which includes the correction roller 31. One end of the correction roller 31 receives the driving force from the driving source 12 through the clutch 32 and the driving gear 33, and the other end is engaged with the driving gear 35 of the one-way gear set through the driving transmission gear 34. The one-way gear set includes the driving gear 35, the intermediate gear 36, and the driven gear 37, which is engaged with the cam gear 67. Therefore, the driving force of the conveying unit 30 can be transmitted to the cam gear 67 to drive the connecting rod 63 and the push handle 65.

[0144] As shown in Figure 10 and Figure 11 The one-way gear set is arranged such that the intermediate gear 36 can move in the axial direction between the driving gear 35 and the driven gear 37, and the driving gear 35 unidirectionally transmits the driving force to the driven gear 37 through the intermediate gear 36.

[0145] Specifically, the driving gear 35 is provided with a first engaging portion 351 on the end face on the side facing the intermediate gear 36, and the intermediate gear 36 is provided with a second engaging portion 361 on the end face on the side facing the driving gear 35. The second engaging portion includes a first limiting portion 3611, a second limiting portion 3612, and an abutting inclined surface 3613. The first limiting portion 3611 is arranged at the bottom end of the abutting inclined surface 3613 (close to the end face on the gear axial direction), the second limiting portion 3612 is arranged at the top end of the abutting inclined surface 3613 (far from the end face on the gear axial direction), and the abutting surface of the first limiting portion 3611 is larger than the abutting surface of the second limiting portion 3612.

[0146] The driven gear 37 is provided with a third engaging portion 371 on the end face on the side facing the intermediate gear 36, and the intermediate gear 36 is provided with a fourth engaging portion 362 on the end face on the side facing the driven gear 37. The third engaging portion 371 is provided with a first sawtooth portion 3711, and the fourth engaging portion 362 is provided with a second sawtooth portion 3621 capable of engaging with the first sawtooth portion 3711. The inclined surfaces of the first sawtooth portion 3711 and the second sawtooth portion 3621 face in the opposite direction to the abutting inclined surface 3613.

[0147] Wherein, when looking at the correction roller 31 from the end close to the driving source 12 along the axial direction of the correction roller 31, the direction in which the correction roller 31 rotates counterclockwise is the first direction, and the direction in which the correction roller 31 rotates clockwise is the second direction.

[0148] When the conveying unit 30 is working normally, the controller 11 controls the clutch 32 to engage, the correction roller 31 receives the driving force from the driving source 12 to rotate the conveying sheet in the first direction, and drives the driving transmission gear 34 to engage to rotate in the second direction, at this time, the first engaging part 351 abuts against the first limiting part 3611, the first sawtooth part 3711 and the second sawtooth part 3621 cannot engage, the intermediate gear 36 is pushed towards the driving gear, the driven gear 37 does not rotate, and the cam gear 67 does not rotate, at this time, the intermediate gear 36 is in the first state;
