Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and in particular to a laser printing and forming device and a method thereof. Background Art

[0002] Laser printing is a printing technology that uses a laser beam to quickly "project" digital graphics or documents onto a photosensitive surface. This technology causes electronic discharge by hitting a specific position on the photosensitive drum with a laser beam, which then attracts fine "toner" through static electricity to form a printing effect. The core of laser printing technology lies in laser imaging technology, which enables fast printing speed and high imaging quality, but the relative cost of use is also high. A laser printer is a printing output device that combines laser scanning technology with electronic photography technology, and has the characteristics of fast printing speed and high imaging quality.

[0003] In the current laser printing process, after the photosensitive drum transfers the toner used for printing to the printing paper, toner will inevitably remain on the surface due to long-term use. At the same time, when the toner is in the presence of moisture, it will also remain on the surface of the photosensitive drum. The residual toner will greatly affect the next power printing of the photosensitive drum, causing a decline in subsequent printing quality. In addition, if the residual toner falls off, it will also cause the inside of the printing device to be dirty, which will easily shorten the life of the internal components of the printer in the long run.

[0016] A method for using a laser printing and forming device, which is applied to the laser printing and forming device:

[0017] S1. Before printing, put the printing paper evenly into the paper box, and then plug it into the body from the side wall of the body, then the printing paper in the paper box is transported upward inside the body, and then the printing paper is transported to the bottom of the photosensitive drum, and the charging roller on the side of the photosensitive drum rotates, and the surface of the charging roller is charged to adsorb the transfer toner in the toner cartridge to the surface, and then the laser component emits laser to the laser edge, and then the laser light is reflected by the laser edge to the surface of the photosensitive drum, and the pattern part to be printed is charged with positrons after laser irradiation, and the position without the printed pattern is negative electrons. When the positron part of the photosensitive drum is parallel to the charging roller with toner, the positron can adsorb the toner attached to the charging roller, and then the photosensitive drum rotates with the captured toner to fit the surface of the printing paper, and then the toner is attached to the surface of the printing paper, and the printing paper continues to be transported forward, and then the printing paper passes through the heat transfer roller, and the heat transfer roller heats and squeezes the toner to print on the surface of the printing paper, and the printing and development are completed. Then the printing paper continues to be transported and then output from the paper outlet to complete the entire laser printing molding;

[0018] S2. When the photosensitive drum has finished printing, toner remains on the surface of the photosensitive drum. At this time, the photosensitive drum passes through the position of the scraper, and the scraper scrapes off the residual toner on the surface of the photosensitive drum. Then the scraped toner falls and is adsorbed by the guide plate and introduced into the cleaning tank. The toner accumulates in the cleaning tank and is then dispersed, dried and stirred by the electric stirring rod. After completion, the toner is transported from the cleaning tank to the processing tank;

[0019] S3. The toner stored in the processing tank is pushed by the push plate, and the toner is pushed from the processing tank into the return box. The toner is then transported out of the return box by the feed pipe, and then added back into the toner box by the discharge pipe to complete the recycling.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention can effectively clean and remove the residual toner on the surface of the photosensitive drum by arranging a scraper for cleaning on the moving side of the photosensitive drum and arranging a cleaning box for collecting at the bottom of the scraper, thereby ensuring the cleanliness of the surface of the photosensitive drum, not affecting the subsequent electronic printing, ensuring the effect of the printed content, and at the same time cleaning and collecting the toner, reducing the toner from entering the interior of the printer and causing the impact on the components, thereby ensuring the stable use of the printer;

[0022] 2. In the present invention, after cleaning the photosensitive drum, the toner falls into the cleaning tank of the cleaning box and is collected. The toner is collected in the cleaning tank, and the electric stirring rod in the cleaning tank stirs and breaks the collected toner, and heats it, so that the humidity of the toner is reduced, so that the scraped toner can be used again, thereby improving the reuse rate of toner printing materials and reducing the waste of resources;

[0023] 3. In the present invention, after the toner is recycled, the toner is led out from the processing tank box and the return box, and then transported by the feed pipe and the discharge pipe, and then transported back to the toner box, so as to complete the clean recycling and reuse of the toner, thereby improving the utilization rate of the raw materials, reducing the waste of toner, completing the cleaning of the inside of the printer, and making the toner be efficiently utilized.

[0042] See also Figure 3 , Figure 4 , Figure 6 and Fig. 9 , further improvements were made on the basis of Example 1:

[0043] A slide groove 23 is provided at the top of the inner groove of the processing tank 16, and a slider 25 is slidably connected inside the slide groove 23. The slider 25 is fixedly connected to the top of the push plate 17. A storage groove 26 is provided at the top of the inner groove of the processing tank 16 close to the cover plate 18. A threaded rod 24 is rotatably connected to the inner groove wall of the slide groove 23. The threaded rod 24 penetrates and is threadedly connected to the slider 25. A motor for driving is provided at one end of the threaded rod 24. The motor is embedded and fixed in the inner wall of the storage groove 26 to drive the rotation of the threaded rod 24. The motor is a forward and reverse motor in the prior art and will not be described in detail here.

[0044] A push rod 27 is fixedly connected to the side of the slider 25 opposite to the storage groove 26, a rod hole 28 is connected between the slide groove 23 and the storage groove 26, the push rod 27 is adapted to be plugged into the rod hole 28, a limit block 29 is movably installed in the inner groove of the storage groove 26, and the side of the limit block 29 close to the cover plate 18 is made of plastic, so that when the limit block 29 pushes the cover plate 18 open, no damage will be caused.

[0045] The limit block 29 is fixedly connected to the side wall position of the rod hole 28 with an electromagnetic induction column 31, and the push rod 27 is fixedly connected to one end of the electromagnetic induction column 31 with an electromagnetic induction block. The cover plate 18 is provided with a sub-lock and a main lock of an electromagnetic lock at the position of the through-port 19.

[0046] A No. 1 spring 30 is fixedly connected between the side wall of the limiting block 29 close to the rod hole 28 and the inner groove wall of the receiving groove 26 , and the No. 1 spring 30 facilitates the movement and reset of the limiting block 29 .

[0047] Example 3

[0048] See also Figure 1 , Figure 5 and Figure 6 , further improvements were made on the basis of Example 1:

[0049] A feed screw 32 is rotatably installed inside the feed pipe 21, and a servo motor 33 is installed at the end of the feed pipe 21 away from the return box 20. The output end of the servo motor 33 passes through the end of the feed pipe 21 and is fixedly connected to the feed screw 32.

Then the push rod 27 moves the limit block 29 in the storage slot 26 toward the cover 18, and then the limit block 29 pushes the cover 18 to open. At this time, the toner block is pushed into the return box 20, and then the servo motor 33 is started to drive the feeding screw 32 to rotate, so that the toner block in the return box 20 can be broken and transported, and the recovered toner is transported back to the toner box 4 by the feeding pipe 21 and the discharge pipe 22 for recycling.

Then, the printing paper in the paper box (2) is transported upward inside the machine body (1), and then the printing paper is transported to the bottom of the photosensitive drum (6). The charging roller (5) on the side of the photosensitive drum (6) rotates, and the surface of the charging roller (5) is charged to absorb the transfer toner in the toner box (4) to the surface. Then, the laser component (8) emits a laser to the laser prism (9), and then the laser light is reflected by the laser prism (9) to the surface of the photosensitive drum (6), and the pattern part to be printed is printed by the laser. After irradiation, the photosensitive drum (6) carries positrons, while the position without the printed pattern is negatively charged. When the positron part of the photosensitive drum (6) is parallel to the charging roller (5) carrying the toner, the positrons can absorb the toner attached to the charging roller (5). Then the photosensitive drum (6) rotates with the captured toner to adhere to the surface of the printing paper. Then the toner is attached to the surface of the printing paper. The printing paper is then continuously transported forward. Then the printing paper passes through the heat transfer roller (7). The heat transfer roller (7) heats and squeezes the toner to print on the surface of the printing paper. The printing and developing are completed. Then the printing paper is continuously transported and then discharged from the paper outlet (3). The entire laser printing is completed. S2. When the photosensitive drum (6) has completed printing, toner remains on the surface of the photosensitive drum (6). At this time, the photosensitive drum (6) passes the position of the scraper (12), and the scraper (12) scrapes off the residual toner on the surface of the photosensitive drum (6). The scraped toner then falls and is adsorbed by the guide plate (14) and introduced into the cleaning tank (13). The toner accumulates in the cleaning tank (13), and then is dispersed, dried and stirred by the electric stirring rod (15). After completion, the toner is transported from the cleaning tank (13) to the processing tank (16); S3. The toner stored in the processing tank (16) is pushed by the push plate (17) to push the toner from the processing tank (16) into the return box (20). The toner is then transported out of the return box (20) by the feed pipe (21) and then added back into the toner box (4) by the discharge pipe (22) to complete the recycling.
