Description

Technical Field

[0001] This invention belongs to the field of laser printing technology, specifically relating to a multifunctional integrated self-service error-printing learning machine. Background Technology

[0002] Self-service error correction printing learning machine: A learning aid device that integrates error correction collection, intelligent organization and portable printing functions. It is mainly aimed at students and is used to quickly record, classify and clearly print the errors that occur during the learning process. It helps users efficiently build an error correction notebook, focus on weak knowledge points and improve the effectiveness of review.

[0003] During the printing process, toner residue mainly occurs on the surface of components that come into direct contact with toner and participate in the imaging, transfer, or fixing process. Among them, the amount of toner residue on the surface of the OPC drum core is relatively high. Under normal circumstances, existing technology usually uses a cleaning scraper on one side of the drum core to scrape off the toner residue and recycle it to the waste toner container.

[0004] However, toner on the drum core surface exhibits uneven distribution due to uneven transfer and changes in environmental humidity (such as toner clumping in high-humidity environments). Furthermore, under constant pressure, the resistance in the toner accumulation area increases, leading to varying degrees of wear or burrs on the scraper blade's working surface. Burrs on the cleaning scraper blade can "hook" toner during scraping, causing localized accumulation. Deviations in the straightness of the blade will directly result in uneven contact pressure, creating differences in depth.

[0005] In addition, the abnormal contact pressure between the cleaning scraper and the drum core surface, the continuous action of the cleaning scraper edge on the drum core end face, the sudden increase in frictional resistance, the rapid wear of the edge, and the local burrs;

[0006] Inferior toner particles are uneven or contain hard impurities (such as unmelted resin particles or metal fragments). When the cleaning blade is scraping, these hard particles gradually embed themselves into the edge of the cleaning blade, repeatedly cutting the surface of the cleaning blade edge through friction, leading to accelerated wear and the formation of burrs. At the same time, the toner may be damp and clump together. The hardness of the toner clumps is much higher than that of normal toner. When the cleaning blade is scraping, it is hit and rubbed by the "hard clumps", which leads to local deformation and edge tearing. Summary of the Invention

[0007] To solve the above problems, the present invention adopts the following technical solution: a multi-functional integrated self-service error printing learning machine, including an angle grinder box, a fine grinding unit is provided on one side of the inside of the angle grinder box, and an adjustment unit is provided on the other side of the angle grinder box;

[0008] The fine grinding unit includes:

[0016] Preferably, the vertical sections of the U-panel are symmetrically distributed with four ear plates that are snap-fitted together at the same angle. These are divided into two groups. Two ear plates that are directly opposite each other and from different groups are slidably snap-fitted together with a guide rod, while the other two ear plates are threaded together with a lead screw. The horizontal section of the mortise frame has a keyway. The horizontal section of the mortise frame is slidably snap-fitted together with a T-shaped seat that is slidably snap-fitted together with the keyway.

[0017] Preferably, the vertical sections of the U-panel are symmetrically distributed with two ear seats that are snapped together at the same angle. A section column is provided between the two ear seats, and the section column is slidably snapped together with the ear seats through a bearing. An angle grinding ring is snapped together at the middle position of the outer wall of the section column.

[0018] Preferably, hot melt sheets are snapped onto the opposite faces of the corner plates at the end furthest from the center of the U-panel. Corner rollers are symmetrically arranged near the center of the U-panel on the hot melt sheets. Support plates, snapped onto the corner plates, are rotatably mounted on the outer walls of both ends of the corner rollers. Sanding belts are meshed on the outer walls of the two corner rollers.

[0020] Preferably, the adjustment unit includes:

[0021] Two end brackets are installed symmetrically at both ends of the angle grinder box near the toner cartridge.

[0022] An angle post is rotatably mounted between the two end brackets;

[0023] There are two sets of cleaning scrapers, which are symmetrically and evenly distributed on the outer wall of the corner post. The cleaning scrapers are installed with the corner post through a sliding snap-fit, and the adjacent cleaning scrapers in different sets are staggered. In addition, the end of the cleaning scraper away from the axis of the corner post is shaped like an arrow.

[0024] Two corner plates are symmetrically snapped onto the outer wall of the corner post, and the corner plates are perpendicular to the cleaning scrapers in the adjacent positions.

[0025] The support rod is snapped onto the outer wall of the corner post, and the support rod corresponds one-to-one with the cleaning scraper.

[0026] The shelves are symmetrically and slidably snapped onto the outer wall of the straight rod, and the two shelves in the same group are snapped onto the cleaning scraper at the corresponding positions.

[0027] A threaded rod is provided at the end of one of the two layers in the same group away from the axis of the corner column, and the threaded rod is installed with a threaded engagement with the layer.

[0028] The inner sleeve plate is snapped into the middle position inside the corner column, and the inner sleeve plate is slidably snapped into the outer wall of the shaft section of the cleaning scraper near the axis end of the corner column.

[0029] The telescopic spring is snapped between the cleaning scraper and the inner sleeve plate.

[0030] Preferably, a carbon tube with a rotatable engagement with a corner plate is snapped onto the outer wall of the threaded rod near the axis of the corner column. A serpentine groove is formed on the outer wall of the carbon tube, and a ball rod is slidably snapped onto the inner wall of the serpentine groove. A leaf plate with a slidable engagement with a corner plate is snapped onto the end of the ball rod away from the axis of the carbon tube. A horizontal shaft with a corner plate is slidably snapped onto the vertical sections of the leaf plates. A return spring with a corner plate and a vertical section of the leaf plates is sleeved on the outer wall of the horizontal shaft. Vertical plates are symmetrically snapped onto the outer wall of the horizontal sections of the leaf plates, and pins are snapped onto the vertical plates.

[0031] Preferably, a door frame is snapped onto the outer wall of the horizontal section of the opening frame away from the cover plate, and a spring column is slidably snapped onto the vertical sections of the door frame. A wedge plate is snapped onto the end of the spring column near the axis of the corner column. A powder receiving plate is snapped onto the outer wall of the corner column on the side of the cleaning scraper away from the shelf in the same group. A waste powder box is snapped onto the powder receiving plate and the cleaning scraper in the same group.

[0032] Preferably, a wind plate is snapped onto the outer wall of the angle grinder box near the cover plate, and a wind duct is snapped onto the end of the wind plate near the drum.

[0033] The method for fine grinding and alignment of the cleaning scraper surface inside the printing learning machine, using the aforementioned multi-functional integrated self-service error printing learning machine, is as follows:

[0034] S1: First, the position of different sets of cleaning scrapers is switched through the corner column until a set of cleaning scrapers is kept horizontal (relative to the direction of gravity). Then, the corner tube is controlled by the electric telescopic rod to move the U-panel towards the axis of the corner column, which is the displacement.

[0035] S2: Next, the horizontal movement of the door frame is controlled by the mortise frame. At this time, the wedge plate, under the support of the spring column, continuously interacts with the pins in different areas, causing the leaf plate to control the relative movement of the ball rod and the snake groove on the outer wall of the carbon tube under the linkage support and guidance of the corner plate and the horizontal axis, until the threaded rod, under the synchronous action of the carbon tube, causes the shelf plate to drive the cleaning scraper to move towards the U-panel, until the cleaning scraper contacts the corner tube.

[0036] Subsequently, when the cleaning scraper comes into contact with the corner tube, the carbon tube remains at a constant angle under the limiting action of the threaded rod and the threaded plate. It is relatively self-locking. The ejector pin presses the wedge plate in the opposite direction. Under the support of the door frame, the spring column forces the wedge plate to move in the opposite direction towards the corner tube, so as to avoid collision between the wedge plate and the ejector pin, which would affect the uniform adjustment of the cleaning scraper's level in the remaining area.

[0037] S3: Finally, the power output of the drive motor causes the lead screw to rotate. Under the support and guidance of the guide rod, the ear plate synchronously drives the opposing angle plates to move towards or away from each other to a predetermined position. After that, the hot melt sheet softens the rough edges of the opposite bevel of the cleaning scraper through heating. Then, the relative movement between the sanding belt and the aforementioned bevel is used to finely grind the aforementioned bevel. Subsequently, the instantaneous gas change in the high-pressure chamber cleans the carbon powder particles. The cotton pad, spray chamber, electric heating element and vision sensor are used to complete the supplementary wiping, spraying of maintenance coating, temperature shaping and rough edge monitoring feedback, respectively, to specifically correct the uneven wear of the cleaning scraper blade and improve the rough edge problem.

[0038] The present invention has the following beneficial effects:

[0039] 1. This invention ensures the positive relativity between the hot melt sheet, sanding belt, high-pressure chamber, cotton pad, spray cavity, heating element, and vision sensor and the cleaning scraper by synchronously adjusting the inclined angle between the cleaning scraper and the angle plate. It also specifically refines and adjusts the rough edges of the cleaning scraper's cutting edge, improves the fit between the cleaning scraper and the drum core end face, eliminates "dirt defects" at the source, improves printing cleanliness, reduces toner waste, lowers consumable consumption, ensures consistent and stable printing clarity, and extends the service life of the drum core and cleaning scraper.

[0040] 2. This invention, through the flexible interaction between the wedge plate and the ejector pin, enables the cleaning scraper blade to reduce wear (after the corner tube moves to a predetermined position, there is still a certain "small" gap between the cleaning scraper and the corner tube). Furthermore, due to the segmented layout of the cleaning scraper, the gap between the cleaning scraper and the corner tube varies in different areas, resulting in differences in the same level of the cleaning scrapers within the same group (compared to the drum core end face). The ball rod can provide feedback on any degree of relative movement between the scraper and the carbon tube, and the threaded self-locking property of the threaded assembly between the threaded rod and the layer plate compensates for the aforementioned differences in the gap between the cleaning scraper and the corner tube in different areas, maintaining the horizontal alignment of the cleaning scrapers within the same group and further reducing the phenomenon of "too deep" or "too shallow" local interaction between the cleaning scraper and the toner.

[0062] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0063] It should be noted that the terms "vertical," "horizontal," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0064] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0065] Reference Figure 1 , Figure 2 and Figure 4 It can be seen that a multi-functional integrated self-service error printing learning machine includes an angle grinder 1, a fine grinding unit 2 is provided on one side of the inside of the angle grinder 1, and an adjustment unit 3 is provided on the other side of the angle grinder 1;

[0066] Reference Figure 1 and Figure 2 It is known that a housing 11 is provided on the outside of the angle grinding box 1. A glass plate table 12 is provided at one end of the housing 11. A cover plate 13 is rotatably installed on the end of the glass plate table 12 away from the housing 11. Angle steel plates 14 are symmetrically arranged inside the housing 11 and are snapped onto the inner wall of the housing 11. Paper feed rollers 15 are symmetrically rotatably installed between the two ends of the angle steel plates 14. Transfer rollers 16 are evenly arranged in an array between the two paper feed rollers 15 and are rotatably installed on the angle steel plates 14. A toner cartridge 17 corresponding to the transfer roller 16 is snapped onto the end of the angle steel plate 14 away from the cover plate 13. The toner cartridge 17 is snapped onto the angle grinding box 1, and the rubber surface of the toner cartridge 17 and the angle grinding box 1 are open. In addition, the toner cartridge 17 includes an OPC drum core, a charging roller, a developing roller, a sponge roller, the transfer roller 16, and a toner cartridge.

[0067] Simplified instructions for laser printing:

[0068] First, the user places the original of the learning materials to be printed in the middle area of ​​the surface of the glass platen 12 and straightens the cover plate 13 (to avoid light interference and the original lifting). Then, the device scans the original through the scanning component (not shown in the figure) under the glass platen 12 and converts the image or text information into digital electrical signal "instructions".

[0069] Next, the charging roller applies a uniform electrostatic charge (usually a negative charge) to the surface of the OPC drum core, adding an electrostatic field to the surface of the OPC drum core (preparation for image recording). Then, based on the digital signal obtained from the aforementioned scanning, the device emits a laser beam to irradiate the surface of the OPC drum core until an "electrostatic latent image" consistent with the original image is formed on the surface of the OPC drum core.

[0070] Finally, the developing roller inside the drum 17 adsorbs toner with opposite charge (usually positive charge) from the toner cartridge. When the developing roller comes into contact with the OPC drum core, the toner is adsorbed to the "electrostatic latent image" area on the surface of the aforementioned OPC drum core under the action of electrostatic adsorption, causing the latent image to be converted into a toner image (the paper feed roller 15 rotates under the support of the angle steel plate 14, and transports the paper to be printed from the paper inlet to the transfer area. In specific implementation, the paper feed roller 15 can be driven to rotate by an external motor).

[0071] Meanwhile, as the paper passes through the transfer roller 16, the transfer roller 16 applies an opposite electrostatic charge to the toner (enhancing the adsorption force), adsorbing the toner image on the surface of the OPC drum core onto the paper surface until a toner image consistent with the original is formed on the paper surface.

[0072] It is hereby noted that a gear set of different sizes is provided on one end of the drum 17, and the gear set is connected to the OPC drum core, charging roller, developing roller, sponge roller and transfer roller 16 inside the drum 17. In specific implementation, the rotation requirements of the aforementioned components can be achieved through the gear set and an external motor. The existing technology will not be described in detail here.

[0073] Chassis 11 and cover plate 13: The chassis 11 provides a protective system environment for the core components inside the chassis 11 through physical blocking, and can block the transmission of noise to a certain extent, while preventing users from directly contacting the internal live or high-temperature components; the cover plate 13 flattens the document, further ensuring the scanning clarity, isolating external light interference, and protecting the glass plate 12 and other internal core components.

[0074] Glass platen 12: Provides a flat and light-transmitting environment for holding originals, positioning originals, increasing scanning accuracy, and is wear-resistant, easy to clean, and extends service life.

[0075] Reference Figure 4 , Figure 5 , Figure 6 and Figure 8It can be seen that the adjustment unit 3 includes: two end brackets 31, which are symmetrically snapped onto the two ends of the angle grinding box 1 near the drum 17; an angle post 32, which is rotatably installed between the two end brackets 31; two sets of cleaning scrapers 33, which are symmetrically and evenly distributed on the outer wall of the angle post 32, and the cleaning scrapers 33 are installed with the angle post 32 through a sliding snap-fit, and the adjacent cleaning scrapers 33 in different sets are staggered; in addition, the end of the cleaning scraper 33 away from the axis of the angle post 32 is arrow-shaped; and two angle plates 34, which are symmetrically snapped onto the outer wall of the angle post 32, and the angle plates 34 are perpendicular to the adjacent cleaning scrapers 33.

[0076] Support rod 35 is snapped onto the outer wall of corner post 32, and each support rod 35 corresponds to a cleaning scraper 33; shelf 36 is symmetrically slidably snapped onto the outer wall of the straight rod, and the two shelf 36 in the same group are snapped onto the corresponding cleaning scraper 33; threaded rod 37 is located at the end of the two shelf 36 in the same group away from the axis of corner post 32, and the threaded rod 37 is threaded onto the shelf 36; inner sleeve 38 is snapped onto the middle position inside corner post 32, and the inner sleeve 38 is slidably snapped onto the outer wall of the shaft section of cleaning scraper 33 near the axis of corner post 32; telescopic spring 39 is snapped onto the cleaning scraper 33 and inner sleeve 38;

[0077] Reference Figure 7 It is known that a carbon tube 311 is installed on the outer wall of the threaded rod 37 near the axis of the corner post 32, which is rotatably fitted with the same angle plate 34. A snake groove 312 is opened on the outer wall of the carbon tube 311. A ball rod 313 is installed in sliding engagement with the inner wall of the snake groove 312. A leaf plate 314 is installed in sliding engagement with the same angle plate 34 at the end of the ball rod 313 away from the axis of the carbon tube 311. A horizontal shaft 315 is installed in sliding engagement with the same angle plate 34 between the vertical sections of the leaf plate 314. A return spring 316 is sleeved on the outer wall of the horizontal shaft 315 and is installed in engagement with the same angle plate 34 and the vertical section of the leaf plate 314. Vertical plates 317 are installed in a symmetrical manner on the outer wall of the horizontal section of the leaf plate 314. Pins 318 are installed in engagement between the vertical plates 317.

[0078] Reference Figure 4 , Figure 6 and Figure 9It can be seen that the single track plate 21 is snapped onto the inner wall of the vertical section on one side of the angle grinding box 1; the slotted frame 22 is slidably snapped onto the end face of the single track plate 21 near the middle of the angle grinding box 1; a door frame 321 is snapped onto the outer wall of the horizontal section of the slotted frame 22 away from the cover plate 13; a spring column 322 is slidably snapped onto the vertical sections of the door frame 321; a wedge plate 323 is snapped onto the end of the spring column 322 near the axis of the corner column 32; a powder receiving plate 324 is snapped onto the outer wall of the corner column 32 on the side of the cleaning scraper 33 of the same group away from the shelf 36; a waste powder box 325 is snapped onto the powder receiving plate 324 and the cleaning scraper 33 of the same group.

[0079] An air baffle 331 is snapped onto the outer wall of the angle grinder box 1 near the cover plate 13, and an air duct 332 is snapped onto the end of the air baffle 331 near the toner cartridge 17.

[0080] The horizontal alignment process between cleaning scrapers 33 in different areas of the same group:

[0081] Prerequisite 1: In the specific implementation process, due to the variability of external interference factors, the wear degree of the working surface of the blade of the segmented cleaning scraper 33 varies in different areas;

[0082] Precondition 2: Assume that there is a "virtual plate" (an equivalent reference object exists inside the fine grinding unit 2) at a predetermined position on the side of the cleaning scraper 33 away from the axis of the corner column 32 inside the angle grinding box 1, and the "virtual plate" is directly opposite to all the cleaning scrapers 33 in the same group;

[0083] First, under the support and guidance of the end frame 31, the corner column 32 synchronously controls the position of the two sets of cleaning scrapers 33 to achieve alternating rotation. In specific implementation, the corner column 32 can be rotated by the built-in motor until the cleaning scraper 33 is kept horizontal (with the direction of gravity as a reference, and the cleaning scraper 33 in the horizontal state is the predetermined position to be finely ground and corrected).

[0084] Next, under the support and guidance of the single rail plate 21, the mortise holder 22 (in specific implementation, the length of the angle grinder box 1 is greater than that of the drum 17, that is, the mortise holder 22 is completely housed through the empty areas at both ends of the angle grinder box 1, ensuring the complete coverage of the movement of the fine grinding unit 2 and the cleaning scraper 33) synchronously controls the door frame 321 to move horizontally. In specific implementation, the mortise holder 22 can be moved by an electric slider. During this process, under the support and guidance of the door frame 321, the spring column 322 provides the wedge plate 323 with a driving force that interacts with the extrusion pin 318 in the opposite direction (the elastic coefficient of the spring column 322 itself is greater than that of the return spring 316, so as to ensure that the wedge plate 323 first extrudes the extrusion pin 318 to a certain extent).

[0085] Finally, under the reverse force of the ejector pin 318, the vertical plate 317 synchronously controls the page plate 314 under the combined guiding and limiting action of the corner plate 34 and the horizontal axis 315 (the spring force of the return spring 316 is less than the spring force of the spring column 322, so when the wedge plate 323 contacts the ejector pin 318, the ejector pin 318 moves as a whole away from the axis of the corner column 32, which is the displacement; in addition, the self-restoring force of the return spring 316 is less than the self-locking force between the threaded rod 37 and the layer plate 36. In specific implementation, the snake groove 312 is connected end to end through the straight groove), changing the relative movement degree between the ball rod 313 and the snake groove 312 on the outer wall of the carbon tube 311 (by the continuity between the ball rod 313 and the snake groove 312, the accuracy of arbitrary contact feedback between the wedge plate 323 and the ejector pin 318 is improved).

[0086] Simultaneously, under the synchronous control of the carbon tube 311, the threaded rod 37 rotates at a predetermined angle at the end face of the corner plate 34, causing the layer plate 36 to be further guided by the guide rod 212, forcing the cleaning scraper 33 to move away from the axis of the corner post 32. (And when there are differences in the distance between the cleaning scraper 33 and the aforementioned "virtual plate" in different areas, the degree of interaction between the wedge plate 323 and the ejector pin 318 at different positions also varies accordingly. However, since the position of the "virtual plate" is fixed, and the degree of interaction between the inclined surface of the wedge plate 323 and the ejector pin 318 is a range value, the cleaning scraper 33 at different positions can be corrected to a state of contact with the "virtual plate", thereby unifying the horizontal alignment of the cleaning scraper 33 with the aforementioned OPC drum core surface; in addition, Because the wedge plate 323 has a flexible degree of freedom in the direction of the spring column 322 axis, and the elastic coefficient of the spring column 322 is greater than that of the return spring 316, when the cleaning scraper 33 comes into contact with the "virtual plate" (taking a cleaning scraper 33 in a certain area as an example), at this time, there is a self-locking property given by the threaded assembly itself between the threaded rod 37 and the layer plate 36, and the self-locking force between the threaded rod 37 and the layer plate 36 is greater than the sum of the restoring force of the return spring 316 and the reverse force provided by the spring column 322. This ensures that when the wedge plate 323 comes into contact with the aforementioned state, the ejector pin 318 is instantly forced to press the wedge plate 323 in the opposite direction, and the spring column 322 is compressed until the wedge plate 323 is "misaligned" with the ejector pin 318 and passes by.

[0087] The inner sleeve 38 and the telescopic spring 39 (which buffer and absorb the radial runout of the degradation to a certain extent) further ensure the stability of the cleaning scraper 33 movement;

[0088] This process is repeated until the wedge plate 323 and the ejector pin 318 in each area complete the extrusion interaction;

[0089] Pre-processing of softening toner on the surface of OPC drum core using duct 332: In specific implementation, the ventilation plate 331 is connected to the external air pump and air tank through the external hose, and hot air (temperature 40-50℃, wind speed 0.5m / s) is blown onto the toner area on the surface of OPC drum core through duct 332.

[0090] The waste toner scraped off by the cleaning scraper 33 is collected by the toner receiving plate 324 (the radius of the moving trajectory of the toner receiving plate 324 is smaller than the radius of the moving trajectory of the cleaning scraper 33, and the toner receiving plate 324 serves as an auxiliary receiver; existing printers have waste toner receiving components inside) and the waste toner box 325. The waste toner is then continuously drawn to the outside through the external pipe, air pump, and storage tank, reducing waste toner accumulation and secondary adhesion, and improving the thoroughness of toner residue cleaning.

[0091] The purpose of the staggered cleaning scraper 33 is to fully cover the length of the OPC axis to ensure the degree of cleaning. At the same time, the staggered and segmented layout of the cleaning scraper 33 increases the local shearing force, avoids the problem of "local entanglement" during scraping, and improves the overall uniformity of toner scraping.

[0092] In addition, in specific implementation, the predetermined position of the aforementioned "virtual plate" can be changed (the extreme position is when the initial movement trajectory of the cleaning scraper 33 is tangent to the "bare surface" of the OPC drum core), thereby combining the aforementioned segmented scraping scheme with gradient feed layered scraping processing to further improve the uniformity of scraping.

[0093] Reference Figure 4 , Figure 9 and Figure 11 It is known that the fine grinding unit 2 includes: an electric telescopic rod 23, which is snapped into the middle of the inner wall of the vertical section of the mortise frame 22; a corner tube 24, which is snapped into the end of the electric telescopic rod 23 away from the monorail plate 21; a U-panel 25, which is plugged into the outer wall of the corner tube 24 away from the monorail plate 21; in addition, the U-panel 25 is slidably snapped into the mortise frame 22; fourteen corner plates 26, which are symmetrically divided into two groups and set between the vertical sections of the U-panel 25; and a groove plate 27, which is snapped into the outer wall of the four corner plates 26 on the outside, and the groove plate 27 is slidably snapped into the vertical section of the U-panel 25.

[0094] Reference Figure 5 , Figure 6 and Figure 11It can be seen that there are four ear plates 211 that are symmetrically distributed between the vertical sections of the U-panel 25 and are snapped together by the same angle plate 26. They are divided into two groups. Two ear plates 211 that are facing each other and are in different groups are slidably snapped together with a guide rod 212. The other two ear plates 211 are threaded together with a lead screw 213. The horizontal section of the gusseted bracket 22 has a keyway 214. The horizontal section of the gusseted bracket 22 is slidably snapped together with a T-shaped seat 215 that is slidably snapped together with the keyway 214. The T-shaped seat 215 is rotatably fitted together with the guide rod 212 and the lead screw 213. The outer wall of the horizontal section of the T-shaped seat 215 is snapped together with a drive motor 216 through a mounting seat. The output end of the drive motor 216 is snapped together with the lead screw 213.

[0095] Reference Figure 10 and Figure 11 It can be seen that there are two ear seats 221 that are symmetrically distributed between the vertical sections of the U panel 25 and are snapped together by the same angle plate 26. There is a section column 222 between the two ear seats 221, and the section column 222 is slidably snapped together with the ear seat 221 through the bearing. An angle grinding ring 223 is snapped together at the middle position of the outer wall of the section column 222.

[0096] Reference Figure 10 and Figure 11 It can be seen that hot melt plates 231 are snapped onto the opposite faces of the corner plates 26 at the end furthest from the middle of the U-panel 25. Corner rollers 232 are symmetrically arranged near the middle end of the hot melt plates 231. Support plates 233, snapped onto the corner plates 26, are rotatably mounted on the outer walls of both ends of the corner rollers 232. Sanding belts 234 are meshed onto the outer walls of the two corner rollers 232. The sanding belts 234 are positioned at one end of the hot melt plates 231 and are snapped onto the corner plates 26. The pressure chamber 235 has a cotton pad 236 that is snapped onto the end of the high pressure chamber 235 away from the hot melt sheet 231. The cotton pad 236 has a spray cavity 237 that is snapped onto the end of the cotton pad 236 away from the hot melt sheet 231. The spray cavity 237 has a heating element 238 that is snapped onto the end of the spray cavity 237 away from the cotton pad 236. The heating element 238 has a vision sensor 239 that is snapped onto the end of the heating element 238 away from the spray cavity 237.

[0097] The "smoothing" process of the 33-blade working surface of the cleaning scraper:

[0098] First, under the guidance of the single rail plate 21, the angle plate 26 is synchronously driven to be distributed opposite to the cleaning scraper 33 by the mortise frame 22. Then, the angle tube 24 (which is the equivalent reference of the aforementioned "virtual plate") is controlled by the electric telescopic rod 23 to move the U panel 25 a predetermined distance toward the cleaning scraper 33 until the end face of the cleaning scraper 33 near the U panel 25 is tangent to the angle grinding ring 223.

[0099] Next, when the output shaft of the drive motor 216 rotates, the control screw 213 rotates at a predetermined angle until the slot plate 27, under the support and guidance of the U-panel 25, synchronously controls the angle plate 26 to move towards the designated position (providing stable guidance to the ear plate 211 through the guide rod 212, and the T-shaped seat 215 performs synchronous adaptation movement through the keyway 214 when the electric telescopic rod 23 extends and retracts).

[0100] Finally, the burrs on the opposite bevel of the cleaning scraper 33 are softened by the heating effect of the hot melt sheet 231 (in specific implementation, it can be electrically connected to an external power supply via an external wire). Then, the relative movement between the sanding belt 234 and the aforementioned bevel burrs (in specific implementation, one of the corner rollers 232 is driven to rotate by an external micro motor, and the rotation state of the corner roller 232 is stabilized by a support plate 233) is used to finely grind the aforementioned bevel. Subsequently, the carbon powder particles are cleaned by the instantaneous gas change of the high-pressure chamber 235. The cotton pad 236, spray chamber 237, electric heating element 238 and vision sensor 239 are used to complete the supplementary wiping, spraying of maintenance coating, temperature shaping and burr monitoring feedback respectively (in specific implementation, corner joints can be added to the outer wall of one end of the high-pressure chamber 235 and spray chamber 237, and external air pumps and water pumps can be connected through external hoses to ensure the rationality of the gas source and maintenance coating source). The uneven wear of the cleaning scraper 33 blade edge and the burr problem are specifically corrected.

[0101] It should be noted that, in specific implementation, the aforementioned hot melt sheet 231, high pressure chamber 235 and spray chamber 237 can be added to one side of the angle grinding ring 223 to improve the fine finishing of the vertical outer wall of the cleaning scraper 33 near the U panel 25. At the same time, the section column 222 is driven to rotate by an external motor, so that the angle grinding ring 223 replaces the aforementioned sanding belt 234 to complete the grinding operation of the vertical outer wall of the cleaning scraper 33.

[0102] The working principle of the multifunctional integrated self-service error printing learning machine provided by the present invention is as follows: First step: First, the position of different sets of cleaning scrapers 33 is switched through the corner column 32 until a set of cleaning scrapers 33 is kept horizontal (relative to the direction of gravity). After that, the corner tube 24 is controlled by the electric telescopic rod 23 to drive the U panel 25 to move in the direction of the axis of the corner column 32, that is, to position the displacement.

[0103] Step 2: Next, the door frame 321 is controlled to move horizontally by the frame 22. At this time, the wedge plate 323, under the support of the spring column 322, continuously interacts with the ejector pins 318 in different areas, causing the page plate 314 to control the ball rod 313 to move relative to the snake groove 312 on the outer wall of the carbon tube 311 under the linkage support and guidance of the corner plate 34 and the horizontal axis 315, until the threaded rod 37, under the synchronous action of the carbon tube 311, causes the shelf plate 36 to drive the cleaning scraper 33 to move towards the U-panel 25, until the cleaning scraper 33 contacts the corner tube 24.

[0104] Subsequently, when the cleaning scraper 33 comes into contact with the corner tube 24, the carbon tube 311, under the limiting action of the threaded rod 37 and the threaded plate 36, keeps its angle unchanged and is relatively self-locking. The ejector pin 318 presses the wedge plate 323 in the opposite direction. Under the support of the door frame 321, the spring column 322 forces the wedge plate 323 to move in the opposite direction to the corner tube 24, so as to avoid collision and limitation between the wedge plate 323 and the ejector pin 318, which would affect the uniform adjustment of the horizontality of the cleaning scraper 33 in the remaining area by the wedge plate 323.

[0105] Step 3: Finally, the power output of the drive motor 216 causes the lead screw 213 to rotate. Under the support and guidance of the guide rod 212, the ear plate 211 synchronously drives the opposing angle plates 26 to move towards or away from each other to a predetermined position. Then, the heating effect of the hot melt sheet 231 softens the burrs on the opposite bevel of the cleaning scraper 33. Then, the relative movement between the sanding belt 234 and the aforementioned bevel burrs is used to finely grind the aforementioned bevel. Subsequently, the instantaneous gas change of the high pressure chamber 235 cleans the carbon powder particles. The cotton pad 236, spray chamber 237, electric heating element 238 and vision sensor 239 are used to complete the supplementary wiping, spraying of maintenance coating, temperature shaping and burr monitoring feedback, respectively, to specifically correct the uneven wear of the cleaning scraper 33 blade edge and improve the burr problem.
