Figure 4 It can be seen that when the first bottom plate rises, the toner on the top of the first bottom plate may be pushed to the corner of the powder box, so that the toner occupies the gap between the corner of the powder box and the first bottom plate, and the toner cannot be completely moved to the surface of the third bottom plate. The toner on the first bottom plate and the top of the second bottom plate cannot be completely squeezed to the surface of the third bottom plate, and the toner cannot be fully squeezed, so that a large amount of toner remains in the powder box, thereby affecting the number of prints. Summary of the invention

[0004] The present application proposes a file printing device for human resource management, which has the advantages of uniform toner utilization and dust removal, and is used to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an archive printing device for human resource management, a printer, a maintenance cover and a paper box are fixedly installed on one side of the printer, the paper box is located below the maintenance cover, a control panel is fixedly installed on the top of the printer at the top of the maintenance cover, a paper outlet is provided on the top of the printer at one side of the control panel, a heat dissipation port is provided on the other side of the printer, a side panel is fixedly installed inside the printer, a transfer device is movably installed inside the printer below the paper outlet and on one side of the side panel, a placement cavity is provided in a linear array inside the printer below the transfer device, a powder box is fixedly installed inside the placement cavity, a printing device is movably installed inside the printer between the transfer device and one side of the powder box, and a fan is fixedly installed inside the heat dissipation port.

[0007] Furthermore, a first motor is fixedly installed on one side of the side panel, a second motor is fixedly installed on one side of the side panel at a position corresponding to the position of the printing device, a rail plate is fixedly installed on one side of the side panel above the second motor, a slider is slidably installed inside the rail plate, and a hole groove is opened in the middle of the slider.

[0008] By setting the above structure, when the first motor drives the output shaft to rotate, it drives the top roller to rotate together, and the top roller drives the transfer belt to rotate around the top roller and the outer ring of the transfer belt. When the paper is located between the transfer belt and the OPC drum, it can drive the paper to slide.

[0009] Furthermore, the transfer device includes a top roller and a transfer belt.

When the paper is located between the transfer belt and the OPC drum and rotates for printing, the transfer roller absorbs the toner stained and adsorbed on the outer ring of the OPC drum. Since the paper is added between the transfer belt and the OPC drum, the toner will be adsorbed on the paper, thereby realizing toner transfer.

[0011] Furthermore, the printing device includes an OPC drum, a charging roller, and a developing roller. The OPC drum is rotatably installed inside the printer between the transfer device and the powder box, and the outer ring of the OPC drum is in contact with the outer surface of the transfer belt.

One end of the charging roller passes through the side plate and is fixedly connected to the output shaft of the second motor.

[0012] By setting the above structure and the structural design, the developing roller can be evenly coated with toner by the sponge roller. Due to the electric charge of the outer ring of the OPC drum, the toner on the outer ring of the developing roller is attracted to the outer ring of the OPC drum, and finally attracted by the transfer roller to transfer the toner to the surface of the paper to achieve the printing effect.

[0013] Furthermore, the powder box is provided with an ear groove A and an ear groove B inside, the ear groove A and the ear groove B have the same shape, and top blocks B and A are slidably installed inside the ear groove A and the ear groove B respectively, and the top blocks A and B have the same overall shape, and a first corrugated telescopic plate is fixedly installed on the inner bottom wall of the powder box, a flat plate and a convex angle plate A are provided on the top of the first corrugated telescopic plate, and the angle of the convex angle plate A is matched with that of the top block B, a second corrugated telescopic plate and a third corrugated telescopic plate are fixedly installed on the top of the flat plate of the first corrugated telescopic plate, and a convex angle plate B is provided on the top of the second corrugated telescopic plate, and the angle of the convex angle plate B is matched with that of the top block A.

[0014] Furthermore, a ventilation pipe is fixedly connected between the second corrugated expansion plate and the third corrugated expansion plate, and a first pressure relief valve is provided in the inner cavity of the second corrugated expansion plate on the top surface of the first corrugated expansion plate, and a second pressure relief valve is provided in the inner cavity of the third corrugated expansion plate on the top surface of the first corrugated expansion plate, and the second pressure relief valve is located at the opening of the ventilation pipe in the inner cavity of the third corrugated expansion plate, a laser radiator is fixedly installed on the outer surface of the powder box, and the emission angle of the laser radiator is located at the outer ring of the OPC drum, a sponge roller is rotatably installed on the top of the inner part of the powder box, and the outer ring of the sponge roller is in contact with the outer ring of the developing roller, and an air pump is fixedly installed on one side of the powder box inside the printer, and an air pipe is fixedly connected between the air pump and the inside of the powder box.

[0015] By setting the above structure, the toner inside the powder box can be evenly squeezed, which avoids the toner remaining inside the powder box due to the structural setting, and avoids incomplete utilization of the toner inside the powder box. The toner is fully utilized through the sequential squeezing between the first corrugated telescopic plate, the second corrugated telescopic plate, and the third corrugated telescopic plate, thereby maximizing the benefits for users.

[0016] Furthermore, a heat absorption groove is provided inside the printer between the paper outlet and the heat dissipation port, a dust removal groove is provided inside the printer between the top of the transfer device and the heat dissipation port, and a heating roller and a pressure roller are rotatably installed at the bottom of the paper outlet.

[0017] By setting the above structure, when the paper passes through the heat absorption groove, the air flow rate will be accelerated by the fan, so that the temperature of the paper drops rapidly, thereby achieving cooling of the paper. When the fan is started, the air flow rate inside the heat absorption groove and the dust removal groove is accelerated at the same time, and the wind force is sucked inside the heat absorption groove and the dust removal groove, and the residual toner on the surface of the transfer belt is adsorbed through the dust removal groove, thereby cleaning the surface of the transfer belt and achieving a clean and flawless surface of each paper.

[0018] The present application provides an archive printing device for human resource management, which avoids toner residue in the powder box through structures such as a powder box, a vent pipe, and an air pump. The air pump is started, and the air pump blows the internal gas into the first corrugated telescopic plate through the air pipe. When the first corrugated telescopic plate moves upward to the top, the toner is completely located on the top of the second corrugated telescopic plate and the third corrugated telescopic plate, due to the gas pressure, the gas will enter the second corrugated telescopic plate through the first pressure relief valve, and will push the position of the second corrugated telescopic plate upward. When the second corrugated telescopic plate moves upward to the top, the toner is completely located above the third corrugated telescopic plate. Again due to the gas pressure, the gas will enter the third corrugated telescopic plate through the vent pipe and the second pressure relief valve.

When the transfer belt drives the paper to transfer, toner may remain on the surface of the transfer belt. After the transfer belt rotates again to drive the paper, it will be printed on the surface of the next paper. The residual toner on the surface of the transfer belt is adsorbed by the dust removal groove, so that the surface of the transfer belt is cleaned, and the surface of each paper is clean and flawless, achieving a dust removal effect.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] See also Figure 1-Figure 4A file printing device for human resource management includes a printer 1, a maintenance cover 11 and a paper box 12 are fixedly installed on one side of the printer 1, the paper box 12 is located below the maintenance cover 11, a control panel 13 is fixedly installed on the top of the printer 1, a paper outlet 14 is provided on the top of the printer 1 on one side of the control panel 13, a heat dissipation port 15 is provided on the other side of the printer 1, a side panel 2 is fixedly installed inside the printer 1, a transfer device 3 is movably installed on the side of the side panel 2 and below the paper outlet 14 inside the printer 1, a placement cavity is provided in a linear array below the transfer device 3 inside the printer 1, a powder box 5 is fixedly installed inside the placement cavity, a printing device 4 is movably installed between the transfer device 3 and one side of the powder box 5 inside the printer 1, and a fan 6 is fixedly installed inside the heat dissipation port 15 inside the printer 1.

[0025] By cooperating with each other through the structures in the present invention, the toner can be promptly blown upward during the process of printing the pattern, so that the toner is squeezed inside the powder box 5 and fully contacts the sponge roller 512, so that the accumulation position of the toner is always maintained at an effective position, thereby avoiding the disadvantage that the toner is reduced and cannot fully contact the sponge roller 512 after use.

[0026] See also Figure 1-Figure 5 A first motor 21 is fixedly installed on one side of the side panel 2, a second motor 22 is fixedly installed on one side of the side panel 2 at a position corresponding to the position of the printing device 4, a rail plate 23 is fixedly installed on one side of the side panel 2 above the second motor 22, a slider 24 is slidably installed inside the rail plate 23, and a hole groove is opened in the middle of the slider 24.

[0027] The function of the side plate 2 is to fix the positions of the first motor 21, the second motor 22 and the transfer device 3. When the first motor 21 drives the output shaft to rotate, it drives the top roller 31 to rotate together. The top roller 31 drives the transfer belt 32 to rotate around the top roller 31 and the outer ring of the transfer belt 32. When the paper is located between the transfer belt 32 and the OPC drum 41, it can drive the paper to slide.

[0028] When the second motor 22 drives the output shaft to rotate, it can drive the charging roller 42 to rotate together. When the charging roller 42 rotates, negative charges are applied to the surface of the OPC drum 41, and the OPC drum 41 is driven to rotate together.

[0029] See also Figure 1-Figure 6The transfer device 3 includes a top roller 31 and a transfer belt 32. The top roller 31 is rotatably installed inside the printer 1. One end of the top roller 31 passes through the side plate 2 and is fixedly connected to the output shaft of the first motor 21. When the first motor 21 drives the output shaft to rotate, the top roller 31 is driven to rotate together. The outer ring of the top roller 31 is rotatably sleeved with the transfer belt 32. A transfer roller 33 is rotatably installed above each printing device 4 inside the printer 1. The transfer belt 32 is rotatably sleeved on the outer ring of the transfer roller 33. An auxiliary roller 34 is rotatably installed below the paper outlet 14 inside the printer 1. The auxiliary roller 34 is located on one side of the transfer roller 33 at the outermost edge.

[0030] By designing the above structure, when the top roller 31 rotates, it drives the transfer belt 32 to rotate together. When the paper is located between the transfer belt 32 and the OPC drum 41 and rotates for printing, the transfer roller 33 absorbs the toner stained and adsorbed on the outer ring of the OPC drum 41. Since the paper is added between the transfer belt 32 and the OPC drum 41, the toner will be adsorbed on the paper, thereby realizing toner transfer.

[0031] See also Figure 1-Figure 8 The printing device 4 includes an OPC drum 41, a charging roller 42, and a developing roller 43. The OPC drum 41 is rotatably installed inside the printer 1 between the transfer device 3 and the powder box 5. The outer ring of the OPC drum 41 contacts the outer surface of the transfer belt 32. The charging roller 42 is rotatably installed inside the printer 1 below one side of the OPC drum 41. The outer ring of the charging roller 42 contacts the outer ring of the OPC drum 41. The developing roller 43 is rotatably installed inside the printer 1 below the other side of the OPC drum 41. The outer ring of the developing roller 43 contacts the outer ring of the OPC drum 41. One end of the charging roller 42 passes through the side plate 2 and the output shaft of the second motor 22 Fixed connection, when the second motor 22 drives the output shaft to rotate, it also drives the OPC drum 41, charging roller 42, developing roller 43 and other structures to rotate simultaneously. This connection and engagement structure is a prior art. The innovation of the present invention is not in such structure and no further description is made. The end of the OPC drum 41 rotates through the side plate 2 and is located in the middle hole groove of the slider 24. When the paper passes between the transfer belt 32 and the OPC drum 41, due to the different thickness of the paper, when thick paper passes, the paper will squeeze the OPC drum 41 to move downward. The slider 24 is slidably installed inside the track plate 23, so the OPC drum 41 and the slider 24 have sufficient sliding conditions.

[0032] Through this structural design, the developing roller 43 is evenly coated with toner by the sponge roller 512. Due to the electric charge of the outer ring of the OPC drum 41, the toner on the outer ring of the developing roller 43 is attracted to the outer ring of the OPC drum 41, and finally attracted by the transfer roller 33 to transfer the toner to the surface of the paper to achieve the printing effect.

[0033] See also Figure 1-Figure 8The powder box 5 is provided with an ear groove A51 and an ear groove B52, and the ear groove A51 and the ear groove B52 have the same shape. A top block B54 and a top block A53 are slidably installed inside the ear groove A51 and the ear groove B52 respectively. The top block A53 and the top block B54 have the same overall shape. The corners of the top block A53 and the top block B54 exceed the internal edge line limit of the powder box 5, which is convenient for engaging with the first corrugated telescopic plate 55 and the second corrugated telescopic plate 56. The first corrugated telescopic plate 55 is fixedly installed on the inner bottom wall of the powder box 5. A flat plate and a convex angle plate A are provided on the top of the first corrugated telescopic plate 55. The convex angle plate A is adapted to the angle of the top block B54.

A convex angle plate B is provided on the top of the second corrugated telescopic plate 56, and the convex angle plate B is adapted to the angle of the top block A53.

[0034] When the toner inside the powder box 5 is at a height that cannot fully contact the sponge roller 512, the air pump 513 is started, and the air pump 513 blows the internal gas into the first corrugated expansion plate 55 through the air pipe 514. Since the four sides of the first corrugated expansion plate 55 are corrugated expansion plates, the top surface of the first corrugated expansion plate 55 and the second corrugated expansion plate 56 and the third corrugated expansion plate 57 are squeezed upward, and the position of the toner is moved upward, so that the toner is kept at a height that can fully contact the sponge roller 512. When the toner is continuously consumed, the air pump 513 The gas is continuously blown in. When the first corrugated telescopic plate 55 continuously moves upward and contacts the top block B54, the convex corner of the first corrugated telescopic plate 55 contacts the hypotenuse of the top block B54, squeezing the top block B54 to slide horizontally, and the toner located above the convex corner plate A of the first corrugated telescopic plate 55 is evenly squeezed to the surface of the second corrugated telescopic plate 56 and the third corrugated telescopic plate 57, so as to fully squeeze the toner and avoid the toner being retained in the powder box 5. When the first corrugated telescopic plate 55 moves upward to the top, the toner is completely located on the second corrugated telescopic plate 56. When the second corrugated expansion plate 56 and the top of the third corrugated expansion plate 57 are connected, due to the gas pressure, the gas will enter the second corrugated expansion plate 56 through the first pressure relief valve 59, and the position of the second corrugated expansion plate 56 will be pushed upward, so that the convex angle plate B at the top of the second corrugated expansion plate 56 will contact the bevel edge of the top block A53, and the toner on the top of the second corrugated expansion plate 56 will be squeezed toward the surface of the third corrugated expansion plate 57. When the second corrugated expansion plate 56 moves upward to the top, the toner is completely located above the third corrugated expansion plate 57. The gas will enter the third corrugated telescopic plate 57 through the vent pipe 58 and the second pressure relief valve 510, and the top of the third corrugated telescopic plate 57 will be pushed upward, so that the toner is pushed by the third corrugated telescopic plate 57 to slowly move toward the sponge roller 512. When the top of the third corrugated telescopic plate 57 is at the highest point, the powder box 5 is replaced to ensure that the toner inside the powder box 5 is evenly used. The toner will not be blocked inside the powder box 5, nor will it be blocked by the squeezing of the top of the first corrugated telescopic plate 55 or the second corrugated telescopic plate 56 due to the structural design.

[0035] See also Figure 1-Figure 8A vent pipe 58 is fixedly connected to the inside of the first corrugated telescopic plate 55 between the second corrugated telescopic plate 56 and the third corrugated telescopic plate 57. A first pressure relief valve 59 is provided in the inner cavity of the second corrugated telescopic plate 56 on the top surface of the flat plate of the first corrugated telescopic plate 55. A second pressure relief valve 510 is provided in the inner cavity of the third corrugated telescopic plate 57 on the top surface of the flat plate of the first corrugated telescopic plate 55. The second pressure relief valve 510 is located at the opening of the vent pipe 58 in the inner cavity of the third corrugated telescopic plate 57. A laser radiator 511 is fixedly installed on the outer surface of the powder box 5. The emission angle of the laser radiator 511 is located at the outer ring of the OPC drum 41. The light of the laser radiator 511 can be irradiated on the outer ring of the OPC drum 41. A sponge roller 512 is rotatably installed on the top of the inside of the powder box 5. The outer ring of the sponge roller 512 contacts the outer ring of the developing roller 43. An air pump 513 is fixedly installed on one side of the powder box 5 inside the printer 1. An air pipe 514 is fixedly connected between the air pump 513 and the inside of the powder box 5.

[0036] Through the above structure, the toner inside the powder box 5 can be evenly squeezed, which avoids the toner remaining inside the powder box 5 due to the structural setting, and avoids incomplete utilization of the toner inside the powder box 5. Through the sequential squeezing between the first corrugated telescopic plate 55, the second corrugated telescopic plate 56, and the third corrugated telescopic plate 57, the toner can be fully utilized, thereby maximizing the benefits for users.

[0037] See also Figure 1-Figure 4 A heat absorption groove 16 is provided inside the printer 1 between the paper outlet 14 and the heat dissipation port 15, a dust removal groove 17 is provided inside the printer 1 between the top of the transfer device 3 and the heat dissipation port 15, a heating roller 18 and a pressure roller 19 are rotatably installed at the bottom of the paper outlet 14 inside the printer 1, and the heating roller 18 and the pressure roller 19 cooperate with each other to make the paper and toner more integrated, the air intake port of the fan 6 faces the heat absorption groove 16 and the dust removal groove 17, and the air outlet of the fan 6 faces the opening of the heat dissipation port 15.

[0038] When the paper is just printed, the temperature of the paper will rise after being heated by the heating roller 18 and pressed by the pressure roller 19. When the paper passes through the heat absorption groove 16, the air flow rate will be accelerated by the fan 6, so that the temperature of the paper will drop rapidly, thereby cooling the paper. When the fan 6 is started, the air flow rate inside the heat absorption groove 16 and the dust removal groove 17 will be accelerated at the same time, and the heat absorption groove 16 and the dust removal groove 17 will be attracted by wind. When the transfer belt 32 drives the paper to transfer, there may be residual toner on the surface of the transfer belt 32. After the transfer belt 32 rotates again to drive the paper, it will be printed on the surface of the next paper. The residual toner on the surface of the transfer belt 32 is adsorbed by the dust removal groove 17 to clean the surface of the transfer belt 32, so that the surface of each paper is clean and flawless.

[0039] The working principle of the present invention is as follows: the pickup wheel and other structures inside the printer transport the paper to be printed to the edge between the OPC drum 41 and the transfer belt 32, and the charging roller 42 and the OPC drum 41, the developing roller 43 and other structures are driven to rotate by the second motor 22, and the toner inside the powder box 5 is applied to the developing roller 43 through the sponge roller 512. When the OPC drum 41 rotates, it is negatively charged by the charging roller 42. The irradiation of the laser radiating element 511 converts the irradiated position of the OPC drum 41 into a positive charge, and the toner applied on the outer ring of the developing roller 43 is attracted. When the OPC drum 41 rotates to the corresponding position of the transfer roller 33 through the attraction of the transfer roller 33, the transfer roller 33 attracts the toner. Since the paper is located between the transfer belt 32 and the OPC drum 41, the toner is transferred to the paper, and the top roller 31 and the transfer belt 32 are driven to rotate by the first motor 21. , to realize the transfer of different colors of toner to the surface of the paper in sequence. After the paper is printed with toner, it is driven by the transfer belt 32 to be transported between the heating roller 18 and the pressure roller 19. After being heated by the heating roller 18 and pressed by the pressure roller 19, the temperature of the paper will increase. When the paper passes through the heat absorption groove 16, the air flow rate will be accelerated by the fan 6, so that the temperature of the paper will drop rapidly, so as to realize the cooling of the paper. When the fan 6 is started, the air flow rate inside the heat absorption groove 16 and the dust removal groove 17 is accelerated at the same time, and the heat absorption groove 16 and the dust removal groove 17 are attracted by wind. When the transfer belt 32 drives the paper to transfer, there may be residual toner on the surface of the transfer belt 32. After the transfer belt 32 rotates again to drive the paper, it will be printed on the surface of the next paper. The residual toner on the surface of the transfer belt 32 is adsorbed by the dust removal groove 17 to realize the cleaning of the surface of the transfer belt 32, so that the surface of each paper is clean and flawless. When the toner inside the powder box 5 is used for printing and the position height of the toner cannot fully contact the sponge roller 512, the air pump 513 is started. The air pump 513 blows its internal gas into the first corrugated telescopic plate 55 through the air pipe 514, and squeezes the top surface of the first corrugated telescopic plate 55 and the second corrugated telescopic plate 56 and the third corrugated telescopic plate 57 upward, and moves the toner position upward so that the toner maintains a height that can fully contact the sponge roller 512. When the first corrugated telescopic plate 55 continues to move upward and contacts the top block B54, the convex corner of the first corrugated telescopic plate 55 contacts the hypotenuse of the top block B54, and the top block B54 is squeezed to slide horizontally, and the toner located above the convex corner plate A of the first corrugated telescopic plate 55 is evenly squeezed to the surfaces of the second corrugated telescopic plate 56 and the third corrugated telescopic plate 57, so as to achieve full squeezing of the toner and avoid the toner being retained inside the powder box 5. When the first corrugated telescopic plate 55 moves upward to the top, the toner is completely When the second corrugated telescopic plate 56 and the third corrugated telescopic plate 57 are all located at the top, due to the gas pressure, the gas will enter the second corrugated telescopic plate 56 through the first pressure relief valve 59, and will push the position of the second corrugated telescopic plate 56 upward, so that the convex angle plate B at the top of the second corrugated telescopic plate 56 contacts the hypotenuse of the top block A53, and the toner on the top of the second corrugated telescopic plate 56 is squeezed toward the surface of the third corrugated telescopic plate 57. When the second corrugated telescopic plate 56 moves upward to the top, the toner is completely located above the third corrugated telescopic plate 57. Due to the gas pressure again, the gas will enter the third corrugated telescopic plate 57 through the vent pipe 58 and the second pressure relief valve 510. At this time, the top of the third corrugated telescopic plate 57 will be pushed upward, so that the toner is pushed by the third corrugated telescopic plate 57 to slowly move toward the sponge roller 512. When the top of the third corrugated telescopic plate 57 is at the highest point, the powder box 5 is replaced to achieve uniform utilization of the toner inside the powder box 5.
