Description

Technical Field

[0001] The invention relates to the field of printing consumables production, in particular to a developing roller regeneration method. Background Art

[0002] Toner cartridges are common consumables in laser printers; their excellent printing results provide great convenience for modern office work; but in actual use, the magnetic roller and the developing roller are severely worn after a cycle of use. After a cycle of use and wear, the graphite coating on the surface of the magnetic roller and the developing roller is basically worn out, and the magnetic roller itself loses its original surface roughness. The magnetic roller that has lost its surface roughness cannot generate a large friction with the powder knife, which causes the toner on the surface of the magnetic roller to be unable to obtain sufficient charge through friction. The toner with insufficient charge exhibits serious light color and color cast printing defects during the printing process; therefore, the developing roller needs to be regenerated to restore it to a usable state.

[0003] In the current developing roller regeneration method, the developing roller body needs to be manually sent into different machines such as sandblasting, cleaning and oiling, and each tool needs to be processed separately. Its production efficiency is low and it is difficult to meet the needs of large-scale developing roller regeneration. Summary of the invention

[0039] Reference Figures 1 to 7The developing roller regeneration device of this embodiment includes: a base 100; a telescopic device, which is arranged on the base 100; a telescopic frame 220, which is arranged on the telescopic device, and the telescopic device can drive the telescopic frame 220 to telescope in the front-back direction; a rotating device, which is arranged on the telescopic frame 220; a rotating frame 240, which is arranged on the rotating device, and the rotating device can drive the rotating frame 240 to rotate to position one or position two, and the rotating frame 240 is provided with two clamping claws 260 for clamping the developing roller body 270; a processing box 320, which is arranged on the base 100, The processing box 320 is located at the front side of the telescopic frame 220, and the processing box 320 has a sandblasting module, a cleaning module, an oil injection module and a curing module; when the rotating frame 240 rotates to position one, the telescopic device can drive the telescopic frame 220 to move forward, so that the developing roller body 270 clamped by the two clamps 260 enters the sandblasting module and the oil injection module respectively; when the rotating frame 240 rotates to position two, the telescopic device can drive the telescopic frame 220 to move forward, so that the developing roller body 270 clamped by the two clamps 260 enters the cleaning module and the curing module respectively.

[0040] The present embodiment also provides a developing roller regeneration method, which uses the above-mentioned developing roller regeneration device to regenerate the developing roller body 270, and is characterized in that it includes the following steps performed in sequence: S100, mounting the first developing roller body 270 to be processed on a clamp; S200, controlling the rotating device to rotate the rotating frame 240 to position one; S300, controlling the telescopic device to drive the telescopic frame 220 to move forward, and then controlling the sandblasting module to sandblast the first developing roller body 270 to be processed; S400, controlling the telescopic device to drive the telescopic frame 220 to move backward, and then controlling the rotating device to rotate the rotating frame 240 in the forward direction to position Position 2; S500, control the telescopic device to drive the telescopic frame 220 to move forward, and then control the sandblasting module to spray cleaning liquid for the first developer roller body 270 to be processed; S600, control the telescopic device to drive the telescopic frame 220 to move backward; S700, control the rotating device to rotate the rotating frame 240 from position 2 to position 1 in the positive direction, and then install the second developer roller body 270 to be processed on another clamp; S800, control the telescopic device to drive the telescopic frame 220 to move forward, and then control the oil spraying module to spray oil for the developer roller body 270 to be processed and control the sandblasting module to sandblast the second developer roller body 270 to be processed. S900, control the telescopic device to drive the telescopic frame 220 to move backward, and then control the rotating device to rotate the rotating frame 240 forward to position 1, and then control the telescopic device to drive the telescopic frame 220 to move forward, and then control the curing module to heat and cure the first developer roller body 270 to be processed, and control the cleaning module to spray cleaning liquid for the first developer roller body 270 to be processed.

[0041] By using the above-mentioned developing roller regeneration device, during the production process, the developing roller body 270 can be clamped on the clamping claw 260, and through the cooperation of the telescopic device and the rotating device, the developing roller body 270 can be sent to the sandblasting module, the cleaning module, the oil injection module and the curing module for corresponding process processing; in order to improve efficiency, the second developing roller body 270 can be clamped on the other clamping claw 260 before the first developing roller body 270 is sprayed with oil, and when the first developing roller body 270 is sprayed with oil and cured, the second developing roller body 270 is sandblasted and cleaned synchronously; after the process is completed, the rotating frame 240 can be controlled to rotate, and then the processed first developing roller body 270 can be removed and replaced with the developing roller body 270 to be processed; when the second developing roller body 270 is sprayed with oil and cured, the newly replaced developing roller body 270 is sandblasted and cleaned synchronously; the efficiency of the entire developing roller regeneration method is significantly improved, and it is better adapted to the regeneration of large quantities of developing rollers.

[0042] Specifically, during the production process, the developing roller body 270 can be clamped on the clamping claw 260, and through the cooperation of the telescopic device and the rotating device, the developing roller body 270 is respectively sent to the sandblasting module, the cleaning module, the oil injection module and the curing module for corresponding process processing; in order to improve efficiency, in step S700, the second developing roller body 270 can be clamped on another clamping claw 260 before the first developing roller body 270 is sprayed with oil, and when the first developing roller body 270 is sprayed with oil and cured, the second developing roller body 270 is sandblasted and cleaned synchronously; after step S900, the rotating frame 240 can be controlled to rotate, and then the processed first developing roller body 270 is removed and replaced with the developing roller body 270 to be processed, and steps S800 and S900 are executed cyclically; when the second developing roller body 270 is sprayed with oil and cured, the newly replaced developing roller body 270 is sandblasted and cleaned synchronously; the efficiency of the entire developing roller regeneration method is significantly improved, and it is better adapted to the regeneration of large quantities of developing rollers.

[0043] like Figure 5 As shown, the processing box 320 is divided into four areas, the lower left corner of which is a sandblasting module, and a first nozzle 330 is arranged on the top wall of its internal chamber, and the first nozzle 330 is connected to a sandblasting supply device, and the sandblasting supply device can deliver corundum to the first nozzle 330, and the first nozzle 330 sprays it to the surface of the developing roller to process the surface of the developing roller; the lower right corner of the processing box 320 is a cleaning module, and a second nozzle 340 is arranged on the top wall of its internal chamber, and the second nozzle 340 is connected to a delivery pump. When the delivery pump is running, it can deliver cleaning liquid into the second nozzle 340, and spray it from the nozzle of the second nozzle 340 to the surface of the developing roller to wash away the corundum attached to the surface of the developing roller.

[0044] Furthermore, the upper right corner of the processing box 320 is an oil injection module, and a third nozzle 350 is arranged on the top wall of its internal chamber. The third nozzle 350 is connected to an oil pump, and the oil pump can transport oil to the third nozzle 350. The oil is sprayed from the nozzle of the third nozzle 350 to the surface of the developing roller; the upper left corner of the processor is a curing module, and a hot air device 360 ​​is arranged in its internal chamber. The surface of the developing roller after oil spraying is heated with hot air to solidify the oil.

[0045] Specifically, there are multiple first nozzles 330, and the multiple first nozzles 330 are distributed along the front-to-back direction. After the developing roller is clamped, its axis is also distributed along the front-to-back direction. During sandblasting, the multiple first nozzles 330 simultaneously spray diamond sand, which can make the developing roller be impacted by the diamond sand along its axial direction, so that the impact is uniform. Similarly, there are multiple second nozzles 340 and multiple third nozzles 350, and the multiple second nozzles 340 and multiple third nozzles 350 are all distributed along the front-to-back direction.

[0046] It should be understood that when the rotating device drives the rotating frame 240 to position one, the telescopic frame 220 moves forward, and the developing rollers clamped by the clamps 260 at both ends of the rotating frame 240 can enter the sandblasting module and the oil injection module respectively, and when the rotating device drives the rotating frame 240 to position two, the developing rollers clamped by the clamps 260 at both ends of the rotating frame 240 can enter the cleaning module and the curing module respectively; on the other hand, when the rotating frame 240 drives the developing roller to rotate from the rear of the cleaning module to the rear of the oil injection module, the rotation direction is forward, and when the rotating frame 240 drives the developing roller to rotate from the rear of the cleaning module to the rear of the sandblasting module, the rotation direction is reverse.

[0047] like Figure 1 As shown, the telescopic device includes a telescopic cylinder 210 arranged on the base 100, and the telescopic cylinder 210 can drive the telescopic frame 220 to move forward and backward; in several steps, the telescopic cylinder 210 drives the telescopic frame 220 to move forward, and the developing roller clamped on the clamp 260 can be sent forward into the processing box 320; of course, the telescopic frame 220 can also be driven to move forward and backward by a motor gear rack mechanism or a linear motor mechanism.

[0048] It is worth noting that before the developing roller body 270 enters the processing box 320, a protective cover is put on the end of the developing roller body 270 away from the clamping claw 260 to prevent the end portion of the developing roller from being damaged by sandblasting.

[0049] Specifically, Figure 2 As shown, a slide rail is provided on the cylinder body of the telescopic cylinder 210, and the telescopic frame 220 slides with the slide rail; at this time, the slide rail can limit the forward and backward movement of the telescopic frame 220 to ensure its stable forward and backward movement.

[0050] like Figures 2 to 4As shown, a rotation device is provided on the rotating frame 240, and the rotation device is used to drive the two clamping jaws 260 to rotate relative to the rotating frame 240; wherein, when performing the four processes of sandblasting, cleaning, oil spraying and curing, the rotation device can drive the clamping jaws 260 to rotate, so that the developing roller rotates around its axial direction, ensuring that all directions of its side wall surface can be processed.

[0051] Specifically, the rotation device includes two second motors 250 arranged on the rotating frame 240, and each second motor 250 drives a clamping claw 260 to rotate relative to the rotating frame 240; of course, other mechanisms such as pneumatic motors can also be used to drive the two clamping claws 260 to drive the developing roller to rotate.

[0052] In particular, the developing roller regeneration method also includes step S650 between step S600 and step S700, and step S650 includes: controlling the rotating device to drive the rotating frame 240 to reverse to position one, and then cyclically executing steps S300 to S600; since it is difficult to achieve the required surface roughness by a single sandblasting, it is necessary to repeatedly sandblast and clean the surface of the developing roller. At this time, there is no need to repeatedly clamp. After executing step S600, the rotating device can be controlled to drive the rotating frame 240 to reverse, so that the developing roller body 270 returns to the rear side of the sandblasting module, and then steps S300 to S600 are repeated until the roughness of the developing roller surface meets the requirements and then oil spraying is performed.

[0053] Among them, in step S650, when the roughness of the developing roller meets the requirements, step S700 can be started. Here, the roughness of the developing roller surface can be manually measured after each cleaning, and step S700 can be started when it is detected that the roughness meets the requirements; or an optical roughness meter can be set to automatically detect the surface roughness of the developing roller after each cleaning. When the surface roughness does not meet the requirements, steps S300 to S600 are executed in a loop, and step S700 is executed again when the surface roughness meets the requirements.

[0054] It can be understood that in actual production, the amount of oil after one injection and curing often does not meet the demand, so multiple injection and curing are also required. Therefore, step S950 is also included after step S900. Step S950 includes: controlling the rotating device to drive the rotating frame 240 to reverse to position one, and then cyclically executing steps S800 to S900; at this time, the first motor 230 drives the forward and reverse switching of the telescopic frame 220, and the first developing roller body 270 can repeatedly perform the two steps of oil injection and curing, while the second developing roller body 270 can repeatedly perform the two steps of sandblasting and cleaning, thereby maximizing production efficiency.

[0055] In order to evenly apply the process to various positions on the surface of the developing roller, when the developing roller body 270 is undergoing one of the processes including sandblasting, cleaning, oil spraying or curing, the second motor 250 can be controlled to drive the clamping claw 260 to rotate so that the developing roller body 270 rotates; so that the process can be evenly applied to various positions on the side wall of the developing roller.

[0056] like Figure 1 As shown, a cover plate 310 is provided on the front side of the processing box 320, and avoidance holes are respectively opened on the cover plate 310 at the positions corresponding to the sandblasting module, the cleaning module, the oil injection module and the curing module, and the avoidance holes are suitable for the developer roller body 270 to pass through; when the telescopic frame 220 moves forward, the developer roller on the clamp 260 can pass through the avoidance hole and enter the inner wall of each module; the position of the avoidance hole can be set corresponding to the position of the developer roller, and its diameter is slightly larger than the developer roller; when sandblasting and cleaning are performed, the cover plate 310 can effectively reduce the amount of overflowed corundum and cleaning liquid, and reduce environmental pollution; when oil is sprayed, the cover plate 310 can also reduce the overflow of oil; when curing is performed, the cover plate 310 can also effectively reduce the overflow of hot air, reduce heat loss, and improve the energy efficiency ratio in the production process.

[0057] Specifically, Figures 5 to 8 As shown, the hot air device 360 ​​can adopt an existing hot air blower in the prior art, or can adopt the following structure, wherein the hot air device 360 ​​includes a volute 361 arranged on the inner wall of the curing module, the air inlet of the volute 361 is arranged on the side wall of the processing box 320, and a cross-flow fan is arranged in the volute 361. The axial direction of the cross-flow fan extends in the front-to-back direction, that is, the axial direction of the cross-flow fan is parallel to the axial direction of the developing roller body 270, and can discharge air evenly along the axial direction of the developing roller, and a heating device 363 is arranged at the air outlet of the volute 361 for heating the air blown out by the cross-flow fan.

[0058] Specifically, Figure 7 As shown, the heating device 363 can adopt the PTC heating tube commonly used in the prior art, or can adopt the condenser of the heat pump system to heat the wind blown out by the cross-flow fan through the heat pump system; wherein, a filter screen 321 is also provided at the air inlet of the volute 361 for filtering dust in the incoming air.

[0059] like Figure 5 As shown, a first discharge portion 331 and a second discharge portion 341 are respectively provided below the processing box 320, wherein the first discharge portion 331 is connected to the inner cavity of the sandblasting module. During sandblasting, the diamond sand can be discharged into the sandbox along the first discharge portion 331, and then transported to the first nozzle 330 by the sandblasting supply device for recycling.

[0060] Similarly, the second discharge portion 341 is connected to the inner cavity of the cleaning module. During cleaning, the cleaning liquid can enter the second discharge portion 341 together with the fine steel sand on the surface of the developing roller, and after entering the drying device 421 to dry the corundum, the corundum is sent to the sandbox for reuse.

[0061] Specifically, Figures 8 to 10 As shown, the drying device 421 includes a drying box 410, a feed port 412 is provided on the top cover of the drying box 410, and the feed port 412 is connected to the second discharge portion 341. A stirring frame 431 is provided in the drying box 410, and the stirring frame 431 breaks up the wet and agglomerated corundum under the drive of the stirring motor 430 and promotes the flow of corundum.

[0062] Among them, a drying air duct 420 is arranged at the top of the drying box 410, and both ends of the drying air duct 420 are connected to the drying box 410. A circulating fan 422 is arranged in the drying air duct 420 to promote air circulation between the drying air duct 420 and the inner cavity of the drying box 410; a drying device 421 is arranged in the drying air duct 420 to dry the circulating air. Under the joint action of the stirring frame 431 and the circulating drying air, the corundum wetted by the cleaning liquid can be dried.

[0063] like Figure 8 , Fig. 9 As shown, a discharge gate 411 is provided on the side of the drying box 410 for opening and closing the opening of the side wall of the drying box 410, the opening faces the sandbox, and the bottom of the opening of the side wall of the drying box 410 is flush with the bottom of the inner wall of the drying box 410. When there is a lot of corundum inside the drying box 410, the discharge gate 411 can be opened, and the corundum flows out from the opening under the action of the stirring frame 431 and flows into the sandbox, so that this part of the corundum can also be reused.

[0064] like Fig.10 As shown, the drying device 421 can adopt the water condensation drying device 421 in the prior art, or can adopt the evaporator of the heat pump system, which cools the circulating air so that the water vapor condenses at the fins of the evaporator and is discharged, thereby drying the circulating air.

[0065] In particular, when an evaporator is used as the drying device 421, the evaporator and the condenser acting as the heating device 363 can form a heat pump system together with the compressor. At this time, the heat absorbed by cooling the drying box 410 can be used to solidify the oil on the surface of the developing roller, thereby improving energy utilization and reducing energy consumption.

[0066] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
