Description

Developing cartridge for process cartridge, method of removing the same, removing apparatus, and process cartridge

Technical Field

The present invention relates to a developing cartridge of a process cartridge, a powder removing method of the developing cartridge of the process cartridge, and a removing apparatus of a pre-removal area of the developing cartridge of the process cartridge.

Background

The process cartridge is widely used in image forming developing devices (such as printers or copiers) as a detachable and replaceable consumable office product, and the process cartridge transfers toner in the process cartridge to paper through a linkage print job with the image forming developing device.

In the prior art, according to different types of process cartridges, as shown in fig. 1, the process cartridges include a powder bin, a developing bin and a waste powder bin, carbon powder is arranged in the powder bin, a photosensitive element, a cleaning element and a charging element are arranged in the waste powder bin, and a developing element and a powder control element are arranged in the developing bin. After the process box is assembled, a sealing strip is arranged between the through holes of the powder bin and the developing bin, so that the process box can store and seal carbon powder in the powder bin before the process box is actually used by a user, and the process box is prevented from being influenced by external temperature and humidity environments before the process box is used.

In addition, after the above-mentioned process cartridge is assembled, it is generally necessary to perform a print test on the process cartridge to ensure that the developing quality of the process cartridge meets the set requirements, and since the powder bin is sealed by the sealing strip, an inspector typically applies carbon powder to the developing element or leaves a small amount of carbon powder in the developing bin, so that the process cartridge can perform a print full inspection on the process cartridge without tearing the sealing strip. However, after printing and full inspection, a small amount of toner is usually remained in the developing bin, and the residual toner is not only mixed with the sealed toner in the developing bin after the sealing strip is torn off by a user to cause poor developing quality, but also causes leakage of the residual toner when the processing box jolts during transportation, so that other components in the processing box are polluted.

To solve the above-mentioned potential problems, after the inspector performs printing full inspection on the process cartridge, it is generally necessary to disassemble the process cartridge again to clean the residual toner in the developing hopper or to perform a toner removing (sucking) process on the surface of the developing member, but the developing quality of the process cartridge is liable to change after disassembling the process cartridge and then assembling again.

If an inspector uses a method of installing a process cartridge into an image forming developing device to perform a print job so as to deplete residual toner in a developing hopper, the image forming developing device is worn out and a large amount of paper is wasted during mass production.

Detailed Description

For a better understanding of the technical solution of the present invention, the following detailed description of the embodiments of the present invention refers to the accompanying drawings.

It should be understood that the described embodiments are merely some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1

Referring to fig. 1 and 2, the process cartridge C includes a hopper 200, a developing hopper 100 and a waste hopper 300, a toner 70 is provided in the hopper 200, a photosensitive member 10, a cleaning member 20 and a charging member 30 are provided in the waste hopper 300, a developing member 40 and a toner controlling member 60 are provided in the developing hopper 100, the hopper 200 communicates with the developing hopper 100 through a through-hole 250, a sealing strip 90 seals the through-hole 250, and one end of the sealing strip 90 protrudes outwardly from the side of the process cartridge C.

In addition, since the types of the process cartridges are different, the process cartridges may include only the developing hopper 100, the powder hopper 200, and the components within the developing hopper 100 and the powder hopper 200.

Unlike the prior art, in the structure of the developing cartridge 100 in the first embodiment, as shown in fig. 3, a pre-removal area 151 is provided on the bottom of the cartridge wall 150 in the longitudinal direction of the developing cartridge 100, and the pre-removal area 151 is thinner than the wall thickness of the developing cartridge wall 150 adjacent to the pre-removal area, or the material of the pre-removal area 151 is different from the material of the adjacent developing cartridge wall 150.

After the process cartridge C is assembled, the pre-removing area 151 is outwardly located on the developing chamber 100 of the process cartridge C, and if the pre-removing area 151 is removed from the developing chamber wall 150, the opening formed by removing the pre-removing area 151 can allow the developing chamber 100 to communicate with the inside of the chamber, so as to facilitate the subsequent residual powder removing operation.

In addition, the pre-removal area 151 may be disposed at the bottom of the wall 150 of the developing chamber (near the developing element 40) or may be disposed at the top of the wall 150 of the developing chamber (near the powder controlling element 60), as described with reference to fig. 3 and 5, depending on the different types of cartridge structures and the convenience of the subsequent process operations.

Specifically, the pre-removal zone may be:

The pre-removing area 151 may be a sheet structure, as shown in fig. 4 and 5, in which the thickness of the sheet is thinner on the developing hopper wall 150 than the wall thickness of the adjacent developing hopper wall 150, and the sheet may be disposed on the top of the developing hopper 100 or on the bottom of the developing hopper 100 along the length direction of the developing hopper 100, as shown in fig. 5 to 7. In addition, the number of sheets may be single or plural on the developing chamber wall 150, and the shape of the sheets may be square or circular, as shown in fig. 8.

The material of the pre-removing area 151 may be different from that of the adjacent developing chamber 100, and the material of the pre-removing area 151 is preferably (e.g. soft rubber) softer than that of the adjacent developing chamber 150 (e.g. plastic), or the material of the pre-removing area has a lower impact strength than that of the adjacent developing chamber. In addition, the pre-removing area 151 and the developing chamber 100 may be formed by a single injection molding process or a double injection molding process for facilitating the subsequent process operation.

The above-described modes (a) and (b) may be used alone or in combination.

In addition, a slit 155a may be further provided at the junction of the pre-removal region 151 and the developing hopper wall 150, and the slit 155a may be provided at a side of the junction of the pre-removal region 151 and the developing hopper wall 150 or at an end of the junction of the pre-removal region 151 and the developing hopper wall 150 in the length direction of the developing hopper 100, as shown in fig. 12.

After the process cartridge C having the developing cartridge 100 is assembled and the printing is fully inspected to ensure that the developing quality of the assembled process cartridge C reaches a predetermined standard, the residual powder remaining in the developing cartridge 100 is removed as follows:

Specifically, as shown in fig. 9 and 10, in step a, the pre-removal area 151 can be cut by the cutter K1 when removed, and in the case of the pre-removal area 151 being the mode (one), since the thickness of the sheet is thinner than the wall thickness of the developing cartridge wall 150 adjacent thereto, it is easy to poke or cut the sheet and form the powder removing opening 155, as shown in fig. 11, without affecting the structure of the developing cartridge 100, thereby avoiding affecting the structure and printing quality of the process cartridge C. In the case of the pre-removing area 151 in the second mode, since the material of the pre-removing area 151 is different from that of the adjacent developing cartridge wall 150, the pre-removing area 151 can be easily removed and a powder removing opening can be formed, without affecting the structure of the developing cartridge 100.

In addition, in the first and second embodiments, if the pre-removing area 151 is further provided with the slit 155a, as shown in fig. 12, the pre-removing area 151 can be removed by a tool such as a prying tool K2, so that the removing process is faster and simpler, but since the slit 155a may cause a trace of toner leakage, the slit 155a needs to be sealed by a film when the process cartridge C is assembled, and the film sealed on the slit 155a needs to be removed before the pre-removing area 151 is removed.

B. sucking and removing residual powder in the developing bin through the formed powder removing opening;

Specifically, in step B, the dust collector D1 may suck the residual powder in the developing hopper 100, and since the pre-removing area 151 may be disposed at the bottom of the wall of the developing hopper 100 or at the top of the wall of the developing hopper 100, the residual powder in the developing hopper 100 may be sucked through the formed dust removing opening 155 after the pre-removing area 151 is removed.

C. After residual powder in the developing bin is sucked, sealing the powder removing opening;

Specifically, in step C, as shown in FIG. 14, the formed powder removal opening 155 may be sealed by an adhesive seal 190 (e.g., a glue strip or plastic sheet) or by a plastic sheet welding overlay over the formed powder removal opening 155.

Example two

In the second embodiment, the formation of the pre-removing area on the developing bin 100 requires an additional sheet to be matched, and the bottom of the bin wall in the length direction of the developing bin 100 is pre-provided with the powder removing opening 155 during injection molding, and the length and width of the sheet matched with the powder removing opening 155 need to be capable of completely covering the powder removing opening 155, as shown in fig. 15 and 16, the sheet may be a flexible metal sheet 120 or an adhesive tape 130, and an action part 120a/130a facilitating the pulling operation may be provided on the metal sheet 120 or the adhesive tape 130.

Specifically, before the developing bin 100 is injection molded, the metal sheet 120/adhesive tape 130 is placed in a mold of the developing bin 100 and corresponds to a position of the powder removing opening 155 in the mold, and after the developing bin 100 is injection molded, the sheet can be attached to a bin wall of the developing bin 100 and covers and seals the preset powder removing opening 155.

Step of removing residual powder in the second embodiment:

Reference is made to the step of removing residual powder in the first embodiment, which is different from the step in the first embodiment in the specific detailed implementation manner in the step a:

step A: after the printing full inspection of the processing box is finished, removing the pre-removing area on the developing bin and forming a powder removing opening;

In step a in the second embodiment, before the residual powder in the developing hopper 100 is sucked, the pre-removing area formed by matching the sheet bodies in the second embodiment is removed and the powder removing opening 155 is formed, but since the powder removing opening 155 is reserved for injection molding, the sheet bodies covering and sealing the reserved powder removing opening 155 are simply removed, and the pre-removing area 151 is not required to be poked or cut as in the first embodiment. Specifically, as shown in fig. 17, the sheet body attached to the powder removing opening 155 of the developing bin 100 may be a flexible metal sheet body 120, and after the printing and full inspection of the process cartridge C are completed, the metal sheet body 120 is pulled by an action portion 120a (preferably a pull ring structure) on the surface of the metal sheet body 120 to be bent and separated from the bin wall of the developing bin 100, and finally the powder removing opening 155 preset on the bottom of the bin wall of the developing bin is exposed. In addition, the sheet body attached to the powder removing opening 155 may be an adhesive tape 130, and the acting portion 130a at one end of the adhesive tape 130 may be pulled to separate from the wall of the developing bin 100, so as to finally expose the powder removing opening 155 preset on the bottom of the developing bin wall.

After the step a of the second embodiment is completed, the residual powder may be sucked and the powder removing opening may be sealed, which will not be repeated herein, referring to the step B and the step C of the first embodiment.

In the first embodiment, the pre-removing area in the second embodiment is formed by a sheet body, and the pre-removing area is attached to the pre-determined powder removing opening 155 of the developing chamber 100 after the injection molding of the developing chamber 100 is completed, so that the pre-determined powder removing opening 155 can be exposed only by simply pulling the acting part 120a/130a after the completion of the step a, thereby facilitating the operation of the process.

In addition, in the second embodiment, the sheet for forming the pre-removal area 151 in the second embodiment is not formed by injection molding simultaneously with the developing chamber 100 because the sheet is provided before the injection molding of the developing chamber 100.

Example III

In the third embodiment, as shown in fig. 18, before the developing chamber 100 is formed by injection molding, the additional removing blocks 140 required for forming the pre-removing area are placed in the corresponding positions in the mold of the injection molding developing chamber 100, and during the process of injection molding the developing chamber 100, the melted plastic in the mold surrounds the removing blocks 140 placed in the mold in advance, and after the developing chamber 100 is formed by injection molding, the removing blocks 140 are tightly fitted on the developing chamber 100. The removal block 140 is preferably a circular block or a square block on which the convex portion 140a is projected outward. The removal block 140 may be a material different from the injection molded developing cartridge 100, and the removal block 140 may be a material having a different hardness or/and a different melting point than the developing cartridge 100. The materials with different hardness can enable the removal action to be applied to the removal block 140 due to the difference of the hardness between the pre-removal area (the removal block 140 in the third embodiment) when the pre-removal area is removed, so that the structure of the developing bin 100 is not damaged; the difference in melting points makes the melting point of the material used in the developing hopper 100 lower than that of the material of the removing block 140 when the developing hopper 100 is formed by injection molding, so that the removing block 140 and the developing hopper 100 after injection molding are tightly matched with each other without being completely melted into a whole when the developing hopper 100 is injection molded after the removing block 140 is put into a mold. Of course, the same material may be used for the removing block 140 and the developing cartridge 100, but although the removing of the removing block 140 may be achieved after the injection molding is completed, it is inconvenient to implement and may damage the structure of the developing cartridge 100.

In addition, since the removing block 140 is provided with the protrusion 140a, the protrusion 140a protrudes from the outer surface of the developing hopper 100 after the developing hopper 100 is injection molded.

In addition, the above-described removing block 140 may use a plurality of.

Step of removing residual powder in the third embodiment:

In step a of the third embodiment, before the residual powder in the developing hopper 100 is sucked, the removing block 140 tightly fitted on the developing hopper 100 is removed to form a powder removing opening 155, as shown in fig. 19. In addition, the protrusion 140a protrudes from the outer surface of the developing cartridge 100, so that the removal block 140 can be entirely unscrewed or pulled out of the developing cartridge 100 by acting on the protrusion 140a using a clip, thereby facilitating the operation. In addition, the structure of the developing cartridge 100 is not damaged in the process of removing the entire removing block 140 from the developing cartridge 100 due to the difference in material hardness and/or material melting point between the developing cartridge 100 and the removing block 140.

Example IV

A preferred embodiment is also provided in this example four.
