Description

Technical Field

[0001] The utility model relates to the technical field of automatic production equipment, in particular to a felt lubricating powder coating device and a toner cartridge automatic production line with the felt lubricating powder coating device. Background Art

[0002] Electrophotographic imaging devices such as laser printers, copiers, fax machines, graphic processors, etc. are detachably installed with toner cartridges, and the toner cartridges can provide toner for the printing use of the imaging devices.

[0003] See Figure 1 , the powder bin 11 of the toner cartridge 10 has a powder outlet 111, and the roller body 12 of the toner cartridge 10 is rotatably supported on the two end walls of the powder bin 11 and is located at the powder outlet 111. In order to prevent the toner in the powder bin 11 from leaking out from the fitting gap between the shaft end of the roller body 12 and the end wall of the powder bin 11, felts 13 are respectively pasted on the supporting surfaces of the two end walls of the powder bin 11. The felts 13 are elastic and have a large frictional force, and lubricating powder is coated on the supporting surfaces of the felts 13, so that the shaft end of the roller body 12 is elastically sealed and rotatably supported on the supporting surfaces of the felts 13 smoothly.

[0004] During the production process of the toner cartridge 10, in order to automatically coat lubricating powder on the supporting surface of the felt 13, the existing automatic lubricating powder applying device sends the powder bin 11 to directly below the powder coating mechanism through the feeding mechanism. The motor of the powder coating mechanism drives the felt head to move downward. The felt head enters the powder storage tank to pick up lubrication and then rises. Then the first cylinder drives the powder storage tank away from the felt head. Next, the motor drives the felt head to descend above the powder bin 11. Subsequently, the second cylinder drives the felt head to move downward to perform the lubricating powder applying operation. Moreover, the existing automatic lubricating powder applying device is provided with a leveling mechanism in the powder storage tank. The leveling mechanism includes a third cylinder, the third cylinder is fixedly arranged on the side wall of the powder storage tank, and a chute is arranged on the upper surface of the third cylinder; a fourth connecting member, the fourth connecting member is an L-shaped plate, the short side of the fourth connecting member is fixedly connected with the push rod of the third cylinder, and the long side of the fourth connecting member is slidably matched with the chute on the upper surface of the third cylinder; a powder leveling part, the powder leveling part is arranged in the powder storage tank, the powder leveling part is fixedly connected with the long side of the fourth connecting member through an L-shaped fifth connecting member, the powder leveling part is slightly smaller than the powder storage tank, and the powder leveling part is hollow, so that the powder leveling part moves in the powder storage tank under the drive of the second cylinder to level the lubricating powder, which is more beneficial to the powder picking operation.

[0005] However, the leveling mechanism of the existing automatic lubricating powder spraying equipment uses a second cylinder to drive the powder spreading part to move horizontally only in the powder storage tank to level the lubricating powder in the powder storage tank. Thus, when there is too much lubricating powder in the powder storage tank, the powder spreading end face of the powder spreading part will be submerged in the lubricating powder, that is, the upper end face of the lubricating powder covers above the powder spreading end face of the powder spreading part, resulting in the inability of the powder spreading end face of the powder spreading part to level the upper end face of the lubricating powder, affecting the effect of powder sticking operation. Moreover, the powder spreading part submerged in the lubricating powder moves horizontally in the powder storage tank, which will compact and agglomerate the lubricating powder located below the powder spreading end face of the powder spreading part, thus affecting the uniformity of powder sticking. And when there is too little lubricating powder in the powder storage tank, the powder spreading end face of the powder spreading part is located above the upper end face of the lubricating powder, resulting in the inability of the powder spreading end face of the powder spreading part to contact the upper end face of the lubricating powder to level the upper end face of the lubricating powder, affecting the effect of powder sticking operation. Summary of the Invention

[0006] To achieve the first object of the present utility model, the present utility model provides a felt lubricating powder coating device for efficiently and automatically coating lubricating powder, which can stably supply a quantitative and fluffy lubricating powder to the adhesive head and level the quantitatively and fluffily supplied lubricating powder, so that the powder sticking amount of the adhesive head is uniform and stable, thereby improving the uniformity and stability of lubricating powder coating and further enhancing the production quality.

[0007] To achieve the second object of the present utility model, the present utility model provides a toner cartridge automatic production line having the above-mentioned felt lubricating powder coating device.

[0008] To achieve the first object of the present utility model, the present utility model provides a felt lubricating powder coating device, including an adhesive head and a movement control mechanism. The movement control mechanism can control the movement of the adhesive head in the horizontal direction and / or the vertical direction. The felt lubricating powder coating device further includes a shaft rod, a lifting seat, a lifting control mechanism, a powder cylinder, a stirring frame, a stirring control mechanism, a scraper and a leveling control mechanism. The lifting control mechanism can control the movement of the lifting seat in the vertical direction. The powder cylinder, the stirring frame and the scraper are respectively arranged on the lifting seat. The upper end face of the powder cylinder is concavely provided with a receiving cavity for accommodating lubricating powder in the vertical direction. The upper end face of the shaft rod is concavely provided with a quantitative cavity in the vertical direction. And the powder cylinder is sleeved on the shaft rod movably in the vertical direction so that the lubricating powder in the receiving cavity can be conveyed into the quantitative cavity. The stirring blades of the stirring frame are located in the receiving cavity. The stirring control mechanism is arranged on the lifting seat and can control the stirring blades to rotate around the vertical direction to stir the lubricating powder in the receiving cavity. The leveling control mechanism is arranged on the lifting seat and can control the scraper to move in the horizontal direction, so that the leveling end of the scraper can be located on the upper end face of the shaft rod to move to level the lubricating powder in the quantitative cavity. The outer surface of the adhesive head can adhere to the lubricating powder in the quantitative cavity.

[0009] As can be seen from the above solution, during the working process of the felt lubricating powder coating device of the present utility model, the lifting control mechanism controls the lifting seat to move upward in the vertical direction, synchronously driving the powder cylinder, the stirring frame and the scraper arranged on the lifting seat to move upward in the vertical direction to a preset position. Subsequently, the stirring control mechanism controls the stirring blades to rotate around the vertical direction to stir the lubricating powder in the accommodating cavity of the powder cylinder, so that the lubricating powder in the accommodating cavity of the powder cylinder is stirred and fluffed and conveyed to the quantitative cavity on the upper end surface of the shaft rod. At the same time, the leveling control mechanism controls the scraper to move horizontally to the position to be leveled. Then, the lifting control mechanism of the felt lubricating powder coating device controls the lifting seat to move downward and reset in the vertical direction, synchronously driving the powder cylinder, the stirring frame and the scraper arranged on the lifting seat to move downward and reset in the vertical direction. At this time, the leveling end of the scraper is basically in close contact with the upper end surface of the shaft rod. After that, the leveling control mechanism controls the scraper to move horizontally and reset, so that the leveling end of the scraper moves horizontally on the upper end surface of the shaft rod to level the uneven upper end surface of the lubricating powder in the quantitative cavity. The scraped-off lubricating powder falls into the accommodating cavity of the powder cylinder for recycling. Then, the movement control mechanism controls the adhesion head to move horizontally and / or vertically, so that the adhesion head moves to the quantitative cavity on the upper end surface of the shaft rod, so that the outer surface of the adhesion head adheres to the lubricating powder in the quantitative cavity. After that, the movement control mechanism controls the adhesion head adhered with the lubricating powder to move horizontally and / or vertically, so that the adhesion head moves to the support surface of the felt of the toner cartridge to coat the lubricating powder adhered by the adhesion head on the support surface of the felt.

[0010] In addition, the felt lubricating powder coating device of the present utility model can not only perform automatic lubricating powder coating operation on the support surface of the felt, but also perform automatic powder coating operation on products that need to be coated with powder.

[0011] Therefore, the felt lubricating powder coating device of the present utility model realizes a completely automatic lubricating powder coating operation, with high production efficiency. By controlling the powder cylinder to move upward and accompanied by the rotation of the stirring blades to stir the lubricating powder in the accommodating cavity of the powder cylinder, the lubricating powder in the accommodating cavity of the powder cylinder is stirred and fluffed and conveyed to the quantitative cavity on the upper end surface of the shaft rod. Subsequently, the leveling end of the scraper levels the uneven upper end surface of the lubricating powder in the quantitative cavity. Thus, regardless of the amount of lubricating powder in the accommodating cavity of the powder cylinder, it can ensure that the amount of lubricating powder in the quantitative cavity remains stable, so as to avoid problems of uneven powder adhesion due to too much or too little lubricating powder in the accommodating cavity of the powder cylinder. It can be seen that the felt lubricating powder coating device of the present utility model can stably supply a quantitative and fluffy lubricating powder to the adhesion head, and perform a leveling operation on the quantitatively and fluffily supplied lubricating powder, so that the powder adhesion amount of the adhesion head is uniform and stable, thereby improving the uniformity and stability of the lubricating powder coating, and further improving the production quality.

[0012] A further solution is that the stirring control mechanism and the leveling control mechanism are combined into a driving control mechanism. The driving control mechanism includes a moving seat, a driving component, and a toothed ring part. The driving component is arranged on the lifting seat and can control the moving seat to move in the horizontal direction. The scraper is arranged on the moving seat. The moving seat is provided with a rack, and the rack extends along the moving direction of the moving seat in the horizontal direction. The toothed ring part is connected to the upper end of the stirring blade in the vertical direction, and the toothed ring part is rotatably located on the upper end surface of the powder cylinder and meshes with the rack.

[0013] A further solution is that the toothed ring part protrudes downward in the vertical direction to be provided with a circumferential ring part. The circumferential ring part is rotatably inserted into the accommodating cavity, and the upper end of the stirring blade is connected to the circumferential ring part.

[0014] A further solution is that the lower cavity end of the accommodating cavity in the vertical direction is arranged as a conical cavity. The lower end surface of the stirring blade in the vertical direction has an inclined surface, and the inclined surface is adaptively arranged with the cavity wall of the conical cavity.

[0015] A further solution is that the lower end of the stirring blade in the vertical direction is provided with a through groove. The through groove penetrates through the stirring blade in the horizontal direction and penetrates through the lower end surface of the stirring blade in the vertical direction.

[0016] A further solution is that the number of the stirring blades is at least two, and multiple stirring blades are evenly distributed in the circumferential direction around the shaft rod in the accommodating cavity.

[0017] A further solution is that the felt lubricating powder device further includes an elastic sealing ring. The lower end of the powder cylinder in the vertical direction is provided with a limiting groove. The elastic sealing ring is arranged in the limiting groove and is sleeved on the shaft rod and can move in the vertical direction.

[0018] A further solution is that the adhesion head is a felt head or a sponge head; and / or, the shaft rod is located at the center of the accommodating cavity.

[0019] A further solution is that the movement control mechanism includes a first air cylinder, a second air cylinder, a third air cylinder, a first transfer plate, and a second transfer plate. The first air cylinder can control the first transfer plate to move in the horizontal direction. The second air cylinder is arranged on the first transfer plate and can control the second transfer plate to move in the vertical direction.

[0037] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. Specific implementation manners

[0038] Refer to Figures 2 to 13 , this embodiment discloses a felt lubricating powder coating device 20, including an adhesion head 21, a movement control mechanism, a shaft rod 212, a lifting seat 210, a lifting control mechanism, a powder cylinder 27, a stirring frame 220, a stirring control mechanism, a scraper 28 and a leveling control mechanism. The movement control mechanism can control the adhesion head 21 to move in the horizontal direction and / or the vertical direction. The lifting control mechanism can control the lifting seat 210 to move in the vertical direction. The powder cylinder 27, the stirring frame 220 and the scraper 28 are respectively arranged on the lifting seat 210. Among them, in this embodiment, the upper end surface of the powder cylinder 27 is recessed in the vertical direction to form a receiving cavity 271 for receiving the lubricating powder. The upper end surface of the shaft rod 212 is recessed in the vertical direction to form a metering cavity 2121. And the powder cylinder 27 is sleeved on the shaft rod 212 so as to be movable in the vertical direction, so that the lubricating powder in the receiving cavity 271 can be transferred to the metering cavity 2121. The stirring blades 213 of the stirring frame 220 are located in the receiving cavity 271. The stirring control mechanism is arranged on the lifting seat 210 and can control the stirring blades 213 to rotate around the vertical direction to stir the lubricating powder in the receiving cavity 271. And, in this embodiment, the leveling control mechanism is arranged on the lifting seat 210 and can control the scraper 28 to move in the horizontal direction, so that the leveling end of the scraper 28 can be located on the upper end surface of the shaft rod 212 to move to level the lubricating powder in the metering cavity 2121, and the outer surface of the adhesion head 21 can adhere to the lubricating powder in the metering cavity 2121.

[0039] During the working process of the felt lubricating powder coating device 20 in this embodiment, the lifting control mechanism controls the lifting seat 210 to move upward in the vertical direction, and synchronously drives the powder cylinder 27, the stirring frame 220 and the scraper 28 arranged on the lifting seat 210 to move upward in the vertical direction to a preset position. Subsequently, the stirring control mechanism controls the stirring blades 213 to rotate around the vertical direction to stir the lubricating powder in the receiving cavity 271 of the powder cylinder 27, so that the lubricating powder in the receiving cavity 271 of the powder cylinder 27 is stirred and fluffed and transferred to the metering cavity 2121 on the upper end surface of the shaft rod 212. At the same time, the leveling control mechanism controls the scraper 28 to move in the horizontal direction to the position to be leveled, such as Figure 14As shown. Next, the lifting control mechanism of the felt lubricating powder coating device 20 controls the lifting seat 210 to move downward and reset in the vertical direction, synchronously driving the powder cylinder 27, the stirring frame 220, and the scraper 28 provided on the lifting seat 210 to move downward and reset in the vertical direction. At this time, the leveling end of the scraper 28 is basically in contact with the upper end surface of the shaft rod 212. After that, the leveling control mechanism controls the scraper 28 to move and reset in the horizontal direction, so that the leveling end of the scraper 28 scrapes and moves on the upper end surface of the shaft rod 212 to level the uneven upper end surface of the lubricating powder in the metering cavity 2121, as Figure 15 shown. The scraped-off lubricating powder falls into the accommodating cavity 271 of the powder cylinder 27 for recycling. Then, the movement control mechanism controls the adhesive head 21 to move in the horizontal direction and / or the vertical direction, so that the adhesive head 21 moves into the metering cavity 2121 on the upper end surface of the shaft rod 212. Thus, the outer surface of the adhesive head 21 adheres to the lubricating powder in the metering cavity 2121. After that, the movement control mechanism controls the adhesive head 21 with the adhered lubricating powder to move in the horizontal direction and / or the vertical direction, so that the adhesive head 21 moves to the support surface of the felt 13 of the toner cartridge 10 to coat the lubricating powder adhered by the adhesive head 21 on the support surface of the felt 13.

[0040] In addition, the felt lubricating powder coating device 20 in this embodiment can not only perform automatic lubricating powder coating operations on the support surface of the felt 13, but also perform automatic powder coating operations on products that need to be coated with powder.

[0041] Therefore, the felt lubricating powder coating device 20 in this embodiment realizes fully automatic lubricating powder coating operations, with high production efficiency. By controlling the powder cylinder 27 to move upward and rotating the stirring blade 213 to stir the lubricating powder in the accommodating cavity 271 of the powder cylinder 27, the lubricating powder in the accommodating cavity 271 of the powder cylinder 27 is stirred and fluffed and conveyed to the metering cavity 2121 on the upper end surface of the shaft rod 212. Subsequently, the leveling end of the scraper 28 levels the uneven upper end surface of the lubricating powder in the metering cavity 2121. Thus, regardless of the amount of lubricating powder in the accommodating cavity 271 of the powder cylinder 27, the amount of lubricating powder in the metering cavity 2121 can be ensured to be stable and unchanged, so as to avoid problems of uneven powder adhesion due to too much or too little lubricating powder in the accommodating cavity 271 of the powder cylinder 27. It can be seen that the felt lubricating powder coating device 20 in this embodiment can stably supply a quantitative and fluffy lubricating powder to the adhesive head 21 and level the quantitatively and fluffily supplied lubricating powder, so that the powder adhesion amount of the adhesive head 21 is uniform and stable, thereby improving the uniformity and stability of the lubricating powder coating and further enhancing the production quality.

[0042] Specifically, the stirring control mechanism and the leveling control mechanism of the felt lubricating powder coating device 20 in this embodiment are combined into a driving control mechanism. The driving control mechanism includes a moving seat 214, a driving component, and a gear ring part 216. The driving component is arranged on the lifting seat 210 and can control the moving seat 214 to move in the horizontal direction. The scraper 28 is arranged on the moving seat 214. The moving seat 214 is provided with a rack 215, and the rack 215 extends along the moving direction of the moving seat 214 in the horizontal direction. The gear ring part 216 is connected to the upper end of the stirring blade 213 in the vertical direction, and the gear ring part 216 is rotatably located on the upper end surface of the powder cylinder 27 and meshes with the rack 215. Thus, after the powder cylinder 27, the stirring frame 220, and the scraper 28 move upward in the vertical direction to a preset position, the driving component controls the moving seat 214 to move in the horizontal direction, so that the scraper 28 arranged on the moving seat 214 moves to the position to be leveled in the horizontal direction. Since the gear ring part 216 connected to the stirring blade 213 meshes with the rack 215 arranged on the moving seat 214, the stirring blade 213 is synchronously driven to rotate around the vertical direction to stir the lubricating powder in the accommodating cavity 271 of the powder cylinder 27, so that the lubricating powder in the accommodating cavity 271 of the powder cylinder 27 is stirred and fluffed and conveyed to the quantitative cavity 2121 on the upper end surface of the shaft rod 212; after the powder cylinder 27, the stirring frame 220, and the scraper 28 move downward in the vertical direction to reset, the driving component controls the moving seat 214 to move horizontally to reset, so that the scraper 28 arranged on the moving seat 214 moves horizontally to reset, so that the leveling end of the scraper 28 moves and levels on the upper end surface of the shaft rod 212 to level the uneven upper end surface of the lubricating powder in the quantitative cavity 2121. Since the gear ring part 216 connected to the stirring blade 213 meshes with the rack 215 arranged on the moving seat 214, the stirring blade 213 is synchronously driven to rotate around the vertical direction to stir the lubricating powder in the accommodating cavity 271 of the powder cylinder 27, so as to further stir the lubricating powder in the accommodating cavity 271 of the powder cylinder 27 to keep it in a fluffy state all the time, thereby avoiding the phenomenon of caking of the lubricating powder in the accommodating cavity 271 of the powder cylinder 27. Further, the driving component in this embodiment is a driving cylinder 29, and the lifting control mechanism in this embodiment is a lifting cylinder 211.

[0043] Thus, the felt lubricating powder coating device 20 in this embodiment can drive the scraper 28 and the stirring blade 213 to move simultaneously through the linkage cooperation of the driving component, the gear ring part 216, and the rack 215, avoiding the problems of increased production cost and large occupation of working space caused by separately setting two control mechanisms to control the movement of the scraper 28 and the stirring blade 213 respectively. Therefore, the felt lubricating powder coating device 20 in this embodiment can drive the scraper 28 and the stirring blade 213 to move simultaneously by setting one driving control mechanism, which can save production cost and reduce the occupation of the working space at the same time.

[0044] In order to enhance the smooth and reliable rotational movement of the toothed ring portion 216 connected to the stirring blade 213, in this embodiment, the toothed ring portion 216 is provided with a circumferential ring portion 217 protruding downward in the vertical direction. The circumferential ring portion 217 is rotatably inserted into the receiving cavity 271, and the upper end of the stirring blade 213 is connected to the circumferential ring portion 217. Specifically, in this embodiment, the stirring blade 213, the circumferential ring portion 217, and the toothed ring portion 216 are integrally formed to constitute a component of the stirring frame 220 in this embodiment.

[0045] Furthermore, the lower cavity end of the receiving cavity 271 in the vertical direction in this embodiment is provided as a conical cavity. The lower end surface of the stirring blade 213 in the vertical direction has an inclined surface 2131, and the inclined surface 2131 is adapted to the cavity wall of the conical cavity, so as to better stir the lubricating powder in the lower cavity end of the receiving cavity 271.

[0046] See Figure 16 , which is another embodiment of the stirring frame 220. The lower end of the stirring blade 213 in the vertical direction is provided with a through groove 2132. The through groove 2132 penetrates the stirring blade 213 in the horizontal direction and penetrates the lower end surface of the stirring blade 213 in the vertical direction, so as to further better stir the lubricating powder in the lower cavity end of the receiving cavity 271.

[0047] In order to improve the stirring efficiency and effect of the lubricating powder in the receiving cavity 271, the number of the stirring blades 213 in this embodiment is at least two, and the plurality of stirring blades 213 are evenly distributed at equal intervals in the circumferential direction of the shaft rod 212 in the receiving cavity 271. Specifically, the shaft rod 212 in this embodiment is located at the center of the receiving cavity 271.

[0048] In order to avoid powder leakage at the sleeving gap between the powder cylinder 27 and the shaft rod 212, the felt lubricating powder device 20 in this embodiment further includes an elastic sealing ring 218. The lower end of the powder cylinder 27 in the vertical direction is provided with a limiting groove. The elastic sealing ring 218 is arranged in the limiting groove and is sleeved on the shaft rod 212 so as to be movable in the vertical direction. Under the action of the elastic sealing performance of the elastic sealing ring 218, the lubricating powder in the receiving cavity 271 of the powder cylinder 27 can be prevented from leaking out from the sleeving gap between the powder cylinder 27 and the shaft rod 212.

[0049] Further, the movement control mechanism of this embodiment includes a first cylinder 26, a second cylinder 24, a third cylinder 22, a first transfer plate 25, and a second transfer plate 23. The first cylinder 26 can control the first transfer plate 25 to move in the horizontal direction. The second cylinder 24 is arranged on the first transfer plate 25 and can control the second transfer plate 23 to move in the vertical direction. The third cylinder 22 is arranged on the second transfer plate 23 and can control the adhesive head 21 to move in the vertical direction. Thus, the first cylinder 26 controls the first transfer plate 25 to move in the horizontal direction to drive the second cylinder 24, the third cylinder 22, the second transfer plate 23, and the adhesive head 21 to move in the horizontal direction. The second cylinder 24 is arranged on the first transfer plate 25 and controls the second transfer plate 23 to move in the vertical direction to drive the third cylinder 22 and the adhesive head 21 to move in the vertical direction. The third cylinder 22 is arranged on the second transfer plate 23 and controls the adhesive head 21 to move in the vertical direction. Therefore, when the adhesive head 21 presses into the quantitative cavity 2121 on the upper end surface of the shaft rod 212 for powder sticking operation, the control of the third cylinder 22 on the adhesive head 21 plays a pressure maintaining role, thereby improving the powder sticking operation effect. And when the adhesive head 21 presses onto the support surface of the felt 13 of the toner cartridge 10 to coat lubricating powder, the control of the third cylinder 22 on the adhesive head 21 also plays a pressure maintaining role, thereby improving the powder coating operation effect. Specifically, the adhesive head 21 of this embodiment is a felt head or a sponge head.

[0050] The above embodiments are only preferred examples of the present invention and do not limit the scope of implementation of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features, and principles of the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
