Description

Technical Field

[0001] The invention relates to the technical field of printer toner supply and discharge system structure, in particular to a printer toner cartridge using a waste toner collection component. Background Art

[0002] After receiving the data to be printed, the toner cartridge of the printer with separate drum and toner is sucked out from the cartridge through the magnetic roller and then laid out on the photosensitive drum, which then prints the toner onto the paper. The printed paper is then fixed at high temperature by the fixing assembly to complete the printing. After printing is completed, the photosensitive drum will take the residual toner adsorbed on its surface back to the toner bin through the magnetic roller.

[0003] The publication number is CN115327875A, which discloses a printer toner cartridge using a waste toner collection assembly. The cleaning scraper acts on the photosensitive drum to scrape off the toner on the photosensitive drum and enter the toner bin. In this manner, the scraped toner falls into a fixed position of the toner bin and is close to the photosensitive drum. The waste toner is easy to accumulate and is not easy to slide from the inclined bottom of the toner bin. If not handled in time, the waste toner is easy to contact the photosensitive drum again and is easy to block the gap between the cleaning scraper and the toner bin (the gap is a channel for the waste toner to enter the toner bin).

[0004] To this end, we propose a printer toner cartridge using a waste toner collection component. Summary of the invention

[0007] Furthermore, the movable component includes a motor connected and fixed to the waste powder bin, the output shaft of the motor is connected and fixed to the rotating rod, the rotating rod is L-shaped, a movable groove is provided on the side of the scraper, the rotating rod is inserted into the movable groove and is rotatably connected to a slider, the slider slides in the movable groove, the spring is located in the movable groove and is hung with the slider, and a limiting component is provided on the top of the scraper to keep the scraper in a vertical state for movement.

[0008] Furthermore, the limiting assembly includes two fixed plates connected and fixed to the waste powder bin, a U-shaped plate is slidably fitted on the lower fixed plate, a telescopic sleeve is fixedly connected between the U-shaped plate and the scraper, and a fixed rod connected to the fixed ball is fixedly connected between the two fixed plates.

[0009] Furthermore, the scraping assembly includes a connecting rod, and the first connecting ball and the second connecting ball are fixedly connected at both ends of the connecting rod, respectively. The first connecting ball is movably embedded in the top of the scraper, and the second connecting ball is movably embedded in the edge of the movable disk.

[0010] Furthermore, the scraping assembly also includes a U-shaped frame, the end of the U-shaped frame is fixedly connected to a clamping plate, the engaging plate is slidably matched with the two clamping plates, the middle of the engaging plate is fixedly connected to a connecting rod slidably matched with the two clamping plates, the other end of the connecting rod is fixedly connected to the flattening plate, and the fixed plate is fixedly connected to two pressure plates that press against the U-shaped plate.

[0011] Furthermore, a connecting plate is fixedly connected between the two fixed plates, and a rotating column fixedly connected to the U-shaped frame is rotatably connected to the connecting plate to ensure smooth tilting and rotating switching of the rotating disk.

[0012] Furthermore, the fixed plate is connected to a plurality of pressing balls which are pressed against the movable disk via elastic rods, thereby ensuring the smooth rotation and tilting rotation switching of the rotating disk.

[0013] Furthermore, the clamping plate is in sliding contact with the movable disk, and a wedge-shaped guide plate is fixedly connected to the top of the flat plate to prevent toner from accumulating on the flat plate, and the inclined wedge-shaped guide plate helps to allow the toner to enter the waste toner bin.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The rotating rod makes a circular motion, cooperates with the movable groove, and under the limiting action of the telescopic sleeve rod, the U-shaped plate and the fixed plate, the scraper first tilts horizontally at a small angle, moves in contact with the bottom of the waste toner bin, thereby scraping the waste toner, and then moves upward away from the bottom of the waste toner bin, then tilts horizontally at a small angle and moves back, and finally moves downward, and reciprocates in sequence, so that the scraper reciprocates to dig into the accumulated toner and push the toner to move to the deep of the waste toner bin to avoid toner accumulation;

[0016] When the end of the rotating rod is located at the bottom of the movable groove, the scraper is tightly fitted to the bottom of the waste toner bin under the action of the extrusion spring, thereby pushing the waste into the waste toner bin. When the end of the rotating rod is located at the top of the movable groove, the spring is pulled, thereby moving the scraper upward and away from the bottom of the waste toner bin. After the scraper returns to the position where it does not contact the bottom of the waste toner bin, it falls again and contacts the bottom of the waste toner bin again, thereby completing the pushing of the accumulated materials in the waste toner bin and avoiding accumulation under the cleaning scraper.

[0017] At the same time, the reciprocating scraper, through the action of the connecting rod, on the one hand makes the meshing plate rotate a certain angle and move back and forth, on the other hand makes the inclination angle of the meshing plate change, so that the flattening plate moves at a certain inclination angle to act on the outer surface of the photosensitive drum, and then converts the inclination angle and moves back, thereby arranging the outer surface of the photosensitive drum in a cross manner, so that the toner on the outer surface of the photosensitive drum is evenly distributed and the thickness is consistent, avoiding uneven distribution of toner on the outer surface of the photosensitive drum and the existence of voids in local positions, which is convenient for the subsequent cleaning scraper to scrape off excess toner on the outer surface of the photosensitive drum.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 12The present invention provides a printer toner cartridge using a waste powder collecting assembly, comprising a toner cartridge housing 1 (other structures are detailed in the prior art), a photosensitive drum 2, a charging roller 3 and an ink cartridge assembly 4 are arranged in the toner cartridge housing 1, a waste powder bin 5 and a cleaning scraper 6 movable up and down and cooperating with the photosensitive drum 2; a movable disk 7 and a scraper 8 slidingly cooperating with the inclined bottom of the waste powder bin 5, a rotating rod 9 rotatably connected in the toner cartridge housing 1, a spring 10 is arranged between the rotating rod 9 and the scraper 8, a fixed ball 11 is movably embedded in the middle of the movable disk 7, a meshing plate 12 is meshed on the side of the movable disk 7, and the meshing plate A leveling plate 13 cooperating with the photosensitive drum 2 is fixedly connected to the middle part of the upper part 12; a movable component, the movable component rotates the rotating rod 9 by self-rotation, so that the scraper 8 automatically rises and returns after scraping along the bottom of the waste toner bin 5, and scrapes the waste toner at the bottom of the waste toner bin 5 in turn; a scraping component, the scraping component is used to cooperate with the scraper 8, so that the movable disk 7 and the meshing plate 12 (the movable disk 7 and the meshing plate 12 can make the gear and the toothed plate) reciprocate the leveling plate 13, and at the same time, the inclination angle of the leveling plate 13 is switched in the gap, and the scraper 8 reciprocates to dig into the accumulated toner and push the toner to move to the deep of the waste toner bin 5 to avoid toner accumulation;

[0033] In the present application, the cleaning scraper 6 acts on the photosensitive drum 2 to make the waste enter the waste toner bin 5, and the waste is concentrated at the front end of the waste toner bin 5. The motor 14 moves to rotate the rotating rod 9, so that the rotating rod 9 makes a circular motion. The rotating rod 9 cooperates with the movable groove 15, and under the limiting action of the telescopic sleeve rod 19, the scraper 8 makes a reciprocating motion.

[0034] When the end of the rotating rod 9 is located at the bottom of the movable groove 15, the scraper 8 is tightly fitted to the bottom of the waste powder bin 5 under the action of the squeezing spring 10 (the spring 10 at this time is equivalent to a compression spring), thereby pushing the waste into the waste powder bin 5. When the end of the rotating rod 9 is located at the top of the movable groove 15, the spring 10 is pulled (the spring 10 at this time is equivalent to a tension spring), so that the scraper 8 moves upward and away from the bottom of the waste powder bin 5. After the scraper 8 returns to its original position without contacting the bottom of the waste powder bin 5, it falls again and contacts the bottom of the waste powder bin 5 again, thereby completing the pushing of the accumulated material in the waste powder bin 5 to avoid accumulation below the cleaning scraper 6.

[0035] At the same time, the reciprocating scraper 8, through the action of the connecting rod 21, on the one hand, makes the meshing plate 12 rotate a certain angle, so that the meshing plate 12 reciprocates, and on the other hand, changes the inclination angle of the meshing plate 12, so that the flattening plate 13 moves at a certain inclination angle, acts on the outer surface of the photosensitive drum 2, and then changes the inclination angle and moves back, thereby arranging the outer surface of the photosensitive drum 2 in a cross manner, so that the toner on the outer surface of the photosensitive drum 2 is evenly distributed and the thickness is consistent, avoiding uneven distribution of toner on the outer surface of the photosensitive drum 2 and the presence of voids in local positions, so that the subsequent cleaning scraper 6 can scrape off excess toner on the outer surface of the photosensitive drum 2.

[0036] The movable assembly includes a motor 14 connected and fixed to the waste toner bin 5, the output shaft of the motor 14 is connected and fixed to the rotating rod 9, the rotating rod 9 is L-shaped, a movable groove 15 is penetrated on the side of the scraper 8, the rotating rod 9 penetrates into the movable groove 15 and is rotatably connected to a slider 16, the slider 16 slides in the movable groove 15, the spring 10 is located in the movable groove 15 and is hung on the slider 16, and a limit assembly is provided on the top of the scraper 8 to keep the scraper 8 in a vertical state for movement;

[0037] In the present application, the motor 14 is started, and the output shaft of the motor 14 rotates at the original position, thereby rotating the L-shaped rotating rod 9, one end of the rotating rod 9 rotates at the original position, and the other end performs a circular motion, and the U-shaped plate 18 slides on the fixed plate 17, driving the telescopic sleeve rod 19 to move along the fixed plate 17, and the movable telescopic sleeve rod 19 enables the scraper 8 to move, and the scraper 8 will not rotate the angle, and maintain the vertical state of movement, and the end of the rotating rod 9 performing a circular motion moves in the movable groove 15;

[0038] When one end of the rotating rod 9 is located at the bottom of the movable groove 15, the slider 16 squeezes the spring 10 and elastically compresses (the spring 10 is equivalent to a compression spring at this time), so that the bottom of the scraper 8 is pressed against the inclined bottom of the waste toner bin 5, and the scraper 8 slides along the inclined bottom of the waste toner bin 5, pushing the waste into the interior of the waste toner bin 5;

[0039] Then, when one end of the rotating rod 9 moves toward the top of the movable groove 15, the scraper 8 starts to move back, and at the same time, the spring 10 is pulled, and the length of the spring 10 increases (the spring 10 is equivalent to a tension spring at this time), so that the scraper 8 moves upward, thereby making the scraper 8 away from the bottom of the waste toner bin 5, that is, the scraper 8 retreats without contacting the bottom of the waste toner bin 5;

[0040] When one end of the rotating rod 9 moves downward from the top of the movable groove 15 to the bottom, the spring 10 is compressed, and the scraper 8 contacts the inclined bottom of the waste toner bin 5 again and moves back to the original position;

[0041] Then the scraper 8 is pressed tightly against the inclined bottom of the waste toner bin 5 and moves, reciprocating in sequence, thereby completing the pushing of the accumulated materials in the waste toner bin 5 to avoid accumulation under the cleaning scraper 6 .

[0045] In the present application, the scraper 8 reciprocates (first moves horizontally at a small tilt angle, then moves upward, then moves back horizontally at a small tilt angle, and finally moves downward). When the scraper 8 moves horizontally at a small tilt angle, it drives the connecting rod 21 to move, pulls the movable disk 7, and makes the movable disk 7 rotate, so that the movable disk 7 and the meshing plate 12 move back and forth, and the flattening plate 13 moves along the photosensitive drum 2 at a certain tilt angle.

[0047] In the present application, when the scraper 8 moves upward and downward, the scraper 8 collides with the U-shaped frame 24, and under the action of the connecting rod 21, the inclination angle of the U-shaped frame 24 is switched (thereby changing the inclination angles of the clamping plate 25, the movable disk 7, the meshing plate 12 and the flattening plate 13), and the two ends of the U-shaped frame 24 are switched to press and cooperate with the pressing plate 27, thereby ensuring that the inclination angle of the flattening plate 13 is switched, so that the flattening plate 13 crosses the photosensitive drum 2;

[0048] The connecting rod 26 rotates synchronously at a certain angle to prevent waste from accumulating on the connecting rod 26. In the present application, the movable plate 7 rotates around the fixed ball 11 and tilts.

[0049] A connecting plate 28 is fixedly connected between the two fixing plates 17 , and a rotating column 29 fixedly connected to the U-shaped frame 24 is rotatably connected to the connecting plate 28 , thereby ensuring the stability of the rotation and switching of the U-shaped frame 24 .

The pressing balls 30 and the elastic rods further ensure the tilt angle of the meshing plate 12 , wherein the distribution of the pressing balls 30 is consistent with the distribution direction of the fixed plate 17 .
