[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0021] As attached Figure 1 In the printing device 10 shown, the process box 40 is installed inside the printing device 10 to transfer the toner image to the paper conveyed from the paper feeding unit 20, and finally fix the toner image on the paper through the fixing unit 30.

[0022] like Figure 1 , 2 The processing box 40 shown has an inner cavity 41 for storing carbon powder, and is also provided with a conveying assembly 42 for conveying carbon powder. The conveying assembly 42 can be a spiral rod structure, which conveys carbon powder through a thread. A driver 43 for driving the conveying assembly 42 to rotate is provided on the end face A in the installation direction of the processing box 40, and a conductive sheet 44 is provided on the end face A. The driver 43 is located on the side of the end face A close to the conveying assembly 42, which reduces the drive chain and is conducive to the conduction of the driving force. The conductive sheet 44 is located on the side of the end face A opposite to the driver 43. Through the above arrangement, the vibration generated when the driver 43 rotates can minimize the impact on the contact stability between the conductive sheet 44 and the electrical contact.

[0023] Specifically, Figure 2 As shown, the driver 43 is located at the lower left corner of the end face A, and the conductive sheet 44 is located at the upper right corner of the end face A, further located above the driver 43, and further located downstream in the rotation direction of the driver 43. After the processing box 40 is installed inside the printing device 10, the bottom surface of the processing box 40 is supported and fixed by the frame of the printing device 10, but there will be some installation clearance margin between the top and the inside of the printing device 10. When the driver 43 rotates, a clockwise rotation trend is generated, but because the bottom surface of the processing box 40 is supported, the processing box 40 will not have a rotation displacement, so that the electrical connection between the conductive sheet 44 and the printing device 10 is more stable.

[0024] When the processing box 40 is detachably installed in the printing device 10 along the axial direction of the conveying assembly 42, the driver 43 is connected to the driving head inside the printing device 10 to obtain the driving force from the printing device 10 body, and drives the conveying assembly 42 inside the processing box 40 to rotate to transfer toner, and the conductive sheet 44 will be electrically connected to the electrical contact inside the printing device 10.

[0025] The driver 43 includes a first driver 431 for conveying toner and a second driver 432 for stirring toner. The second driver 432 can be a sheet stirring mechanism 47 or a conveyor belt to move the toner in the inner cavity 41 toward the conveying component 42. The conveying component 42 conveys the toner to the imaging chamber 45. The imaging component 46 arranged in the imaging chamber 45 conveys the toner to the paper delivered from the paper feeding unit 20.

[0026] like Figure 2 As shown, when the process cartridge 40 is installed inside the printing device 10 from the axial direction, in the vertical direction, the second driver 432 is located above the first driver 431, and the conductive sheet 44 is located above the second driver 432. Furthermore, the second driver 432 is located between the first driver 431 and the conductive sheet 44, and is closer to the first driver 431 relative to the conductive sheet 44. Furthermore, the conductive sheet 44 is located below the axis connecting the first driver 43 and the second driver 432. In this way, the stirring mechanism 47 can have a sufficient rotation distance to fully stir the carbon powder in the inner cavity 41, and the electrical connection stability of the conductive sheet 44 will not be affected by vibration.

[0027] like Figure 2 , 3 As shown, a memory chip 48 for recording the amount of carbon powder in the inner cavity is installed on the processing box 40, and the memory chip 48 is installed on the housing of the processing box 40 by means of snaps or screws. The memory chip 48 is installed on the top surface of the processing box 40, the top surface is perpendicular to the end surface A, and the memory chip 48 is adjacent to the conductive sheet 44, which facilitates the electrical connection between the memory chip 48 and the conductive sheet 44. The memory chip 48 is provided with a plurality of electrical contacts 481 for electrical connection with the electrical contacts inside the printing device 10, and the plurality of electrical contacts 481 are arranged along a length direction perpendicular to the processing box 40.

[0028] The first driver 431 and the second driver 432 are connected to the conveying assembly 42 and the stirring mechanism 47 installed inside the processing box 40, respectively. When the processing box 40 is installed in the printing device 10, the storage chip 48 is electrically connected to the electrical contacts inside the printing device 10 and is subjected to the elastic force in the direction B. Since the plurality of electrical contacts 481 are arranged along the longitudinal direction perpendicular to the processing box 40, the elastic force can be concentrated on the end surface A, and the torque generated in the longitudinal direction of the processing box 40 is minimized. When the processing box 40 receives the driving force from the printing device 10 and starts, the first driver 431 and the second driver 432 rotate in the clockwise direction, with the first driver 431 as the axis, and generate torques M1 and M2 respectively. Combined with the force in the direction B on the processing box 40, these three forces act on the processing box 40 in the clockwise direction, generating a total torque M, which will have a certain impact on the stability of the processing box 40.

[0029] In order to maintain the stability of the process box 40 during operation and avoid poor contact between the memory chip 48, the conductive sheet 44 and the electrical contacts of the printing device 10, the present invention sets the force B on the memory chip 48 between the first driver 431 and the conductive sheet 48. Furthermore, the memory chip 48 and the conductive sheet 44 are respectively located above and below the axis connecting the first driver 431 and the second driver 432. In combination with the second driver 432 being closer to the first driver 431 than the conductive sheet 44, the torque M2 is closer to the rotation axis of the process box 40, thereby ensuring the stability of the process box 40 during operation.

[0030] As described above, the position of the first driver 431 and the second driver 432 generating the power source and the force B are set to reduce the influence of the vibration of the processing box 40 on the contact stability of the conductive sheet 44 and the storage chip 48. The present invention also sets a positioning structure on the end face A for the stability of the mounting structure of the processing box 40, such as the first and second positioning columns 491 and 492, and the positioning groove structure can also be adopted. The first positioning column 491 is set at a position close to the first driver 431 and the second driver 432, and is located between the first driver 431 and the second driver 432, so that the vibration and torque of the two drivers can be balanced. The second positioning column 492 is set at a position close to the conductive sheet 44, or close to the storage chip 48, that is, away from the first driver 431 and the second driver 432, to bear the pressure of the storage chip 48. In this way, the first positioning column 491 and the second positioning column 492 are set on the left and right sides of the processing box 40, which can bear and balance the torque and force generated when the processing box 40 is driven.

Any technician in the field to which the present invention belongs can make any modifications and changes in the form and details of implementation without departing from the spirit and scope disclosed in the present invention, but the patent protection scope of the present invention shall still be subject to the scope defined by the attached claims.
