Ordinary printers are not suitable for filling out file covers, and writing robots need to be manually placed to print cover pages. Moreover, only one page can be placed at a time, and single-sheet writing is inefficient and cannot meet office needs at all. Summary of the invention

[0003] The purpose of the present invention is to address the above-mentioned deficiencies and to provide an archive cover filling printer, which is an office automation equipment suitable for archive cover filling and capable of continuous printing operations. It can print 500 pages continuously in one batch loading of paper, thereby reducing manual intervention, improving office efficiency, and meeting office automation needs.

[0004] A file cover filling printer is implemented by adopting the following technical solutions:

[0005] The utility model relates to a file cover filling printer, which is composed of a machine body, a paper storage bin, a paper feeding mechanism, a writing and printing mechanism, and a paper taking and removing mechanism.

[0006] The fuselage body is the fixed installation base of all functional mechanisms. The fuselage body includes structural parts such as a lower base plate, supporting columns, and an upper bearing plate to form a box-shaped frame. Each functional mechanism component is installed and fixed at a corresponding position of the fuselage body.

[0007] The paper storage bin is arranged in the middle of the machine body and is used for storing archive cover paper.

[0008] The paper feeding mechanism is arranged in the middle of the machine body and is a feeding and conveying component for the archive cover paper.

[0009] The writing and printing mechanism is arranged on the upper part of the machine body and is a printing component with the function of moving along the three axes of X, Y and Z.

[0010] The paper removal mechanism is arranged on one side of the upper part of the machine body and is a component for removing the archive cover paper.

[0011] The paper storage bin is a box structure for storing archive covers, with an opening facing upward, and includes a paper support, a guide column, a guide column fixing sleeve, a ball guide sleeve, a side wall baffle, a paper storage bin baffle, a clamping force sensor, a paper shortage signal photoelectric sensor A, etc. The paper support is used to carry archive cover paper, the ball guide sleeve is fixed on the four corners of the bottom plate of the paper support, and the guide column is fixed on the lower bottom plate through the guide column fixing sleeve. The ball guide sleeve is sleeved on the guide column, and the paper support can move up and down along the guide column. The side wall baffles are respectively fixed on the four sides of the paper storage bin opening on the bottom surface of the upper bearing plate to ensure that the paper does not deviate. The paper storage bin baffles are respectively fixed on the outer edges of the paper storage bin opening on the top surface of the upper bearing plate, and the edges on the paper removal side are not installed. There is a paper storage bin baffle straddling above the paper storage bin opening, and the two ends are fixed on both sides of the paper storage bin opening to limit the paper feeding position and flatten the paper surface. The clamping force sensor is placed on the lower plane of the paper storage bin baffle to provide a paper feeding in place signal. Photoelectric sensor A is fixed on the bottom plate of the paper support. When there is no paper, photoelectric sensor A sends out a paper-out message.

[0012] The paper feeding mechanism is a paper feeding and conveying component for archive cover paper, including a paper feeding driving stepper motor A, a stepper motor bracket A, a third elastic coupling, a ball screw, a screw slider, a ball screw bracket, a bracket fixing base plate, a paper feeding mechanism bracket, an L-shaped connector, a zero position photoelectric sensor A, an induction baffle A, etc. The stepper motor A is fixed to the stepper motor bracket A and connected to the ball screw through the third elastic coupling. Ball bearings are installed at both ends of the ball screw and fixed to the ball screw bracket. The bracket for fixing the motor and the bracket for fixing the ball screw are fixed together on the bracket fixing plate to form a paper feeding mechanism. The paper feeding mechanism is fixed to the lower base plate of the chassis body through the paper feeding mechanism bracket, the screw slider is sleeved on the ball screw, and the screw slider is fixedly connected to the paper support through the L-shaped connector. When feeding paper, stepper motor A drives the lead screw to rotate, and the ball screw drives the paper holder to move upward along the guide column through the lead screw slider. When the paper is in place, the paper is pressed tightly, and the pressing force sensor gives a signal that the paper is in place. Stepper motor A stops rotating, and the writing and printing mechanism starts working. When the paper is used up and there is a paper shortage, the photoelectric sensor A gives a paper shortage signal, and the control system starts stepper motor A, drives the ball screw to rotate in the opposite direction, and the ball screw drives the paper holder to return to the origin zero position through the lead screw slider. The induction baffle A fixed on the lead screw slider returns to the origin zero position together with the lead screw slider. After reaching the origin zero position, the induction baffle A blocks the light source of the zero position photoelectric sensor A fixed on the lower end of the bracket fixing plate, and the zero position photoelectric sensor A sends a signal that it is in place, and stepper motor A stops rotating. Manual paper loading is performed again.

[0013] The writing and printing mechanism is an inkjet printing component with the function of moving along the three axes of X, Y and Z, and the print head can also be replaced with a writing pen. It includes an X-axis linear moving module, a Y-axis linear moving module, a Z-axis linear moving module and a print head. The linear module includes a stepping motor, a linear guide rail, a moving slide, a zero position signal sensor and an end point signal sensor. The two pairs of X-axis linear moving modules are respectively fixed on both sides of the paper storage port on the top surface of the upper bearing plate, the two ends of the Y-axis linear moving module are respectively fixed on the X-axis moving slide, the Z-axis linear moving module is fixed on the Y-axis moving slide, and the moving direction of the Z-axis moving slide is perpendicular to the paper surface. The print head is fixed on the Z-axis moving slide, and the print head adopts an inkjet print head or a writing pen.

[0014] The inkjet print head or writing pen is fixed on the Z-axis moving slide. After receiving the paper supply in place signal, under the control of the printer software, the stepper motors on the X-axis, Y-axis, and Z-axis linear moving modules drive the X-axis, Y-axis, and Z-axis moving slides to move along the linear guide rails, and the inkjet print head or writing pen moves in the three directions of the X-axis, Y-axis, and Z-axis, and the inkjet print head or writing pen prints out various texts or patterns. After printing, the print head returns to the origin, the zero position signal sensor sends a signal of in place, and the control system sends a command to remove the paper.

[0015] The paper removal mechanism is a file cover paper removal component, and includes a suction paper removal component, a pickup wheel paper winding component, a static electricity ion removal fan, a paper passing signal photoelectric sensor B, etc.

[0016] The adsorption paper picking assembly includes a vacuum pump, a vacuum suction cup, a suction cup shaft, a suction cup shaft bracket, a first elastic coupling, a stepper motor B, a stepper motor bracket B, a suction cup zero position photoelectric sensor B, an inductive baffle B, etc. The stepper motor B is fixed to the stepper motor bracket B to drive the suction cup shaft to rotate. The vacuum suction cup is fixed to the suction cup shaft, and ball bearings are installed at both ends of the suction cup shaft and fixed to the suction cup shaft bracket. One end of the suction cup shaft is connected to the stepper motor B through the first elastic coupling, and the other end is installed with an inductive baffle B. The vacuum pump is fixed to the lower bottom plate, and the adsorption paper picking assembly straddles above the paper storage bin opening, close to the inner side of the edge of the paper storage bin opening in the direction of paper removal, and the suction cup faces the area on the archive cover paper that does not need to be printed. The motor brackets and shaft brackets at both ends of the adsorption paper picking assembly are fixed on both sides of the paper storage bin opening on the top surface of the upper bearing plate. When the suction cup is facing the file cover paper surface, the sensing baffle B is in a position to block the light source of the zero position photoelectric sensor B fixed on the suction cup shaft bracket, indicating that the suction cup is in the zero position.

[0017] The pickup wheel paper winding assembly comprises a pickup wheel, a pickup wheel shaft, a pickup wheel shaft bracket, a roller shaft, a second elastic coupling, a transmission gear, a stepper motor C, a stepper motor bracket C, etc. The stepper motor C is fixed on the stepper motor bracket C to drive the pickup wheel shaft to rotate. The pickup wheel is fixed on the pickup wheel shaft, and ball bearings are installed at both ends of the pickup wheel shaft and the roller shaft, and the pickup wheel shaft and the roller shaft with ball bearings installed at the shaft ends are fixed together on the pickup wheel shaft bracket. One end of the pickup wheel shaft and the roller shaft has a shaft head extending out of the ball bearing, and a pair of transmission gears are installed at this shaft extension to realize the reverse rotation of the roller shaft and the pickup wheel shaft. The pickup wheel shaft also has a shaft extension extending out of the transmission gear and connected to the stepper motor C through the second elastic coupling. The pickup wheel paper winding assembly is fixed parallel to the top surface of the upper bearing plate outside the adsorption paper picking assembly.

[0018] The anti-static ion fan is used to eliminate the static adsorption between the archive cover paper and prevent the archive cover paper from sucking the paper below when it is removed. The anti-static ion fan is fixed to the top surface of the upper bearing plate on the side of the paper storage bin opening inside the adsorption paper removal component, and the air outlet faces the side of the archive cover in the paper storage bin.

[0019] The paper passes through the signal photoelectric sensor B fixed on the top surface of the upper bearing plate below the outer side of the pickup wheel and the paper winding assembly. When the archive cover roll is stuck between the pickup wheel and the roller, the paper passes through the signal photoelectric sensor B and sends a paper jam signal, and the control system stops and waits for manual processing.

[0020] When a page of the file cover is printed, the paper removal mechanism receives the command from the control system to start working, the vacuum pump starts, and the vacuum suction cup sucks the file cover. The paper feeding mechanism starts and moves downward to loosen the compressed file cover to facilitate the removal of the file cover. The anti-static ion fan starts to blow away the file covers that are adsorbed together to ensure that only the top printed file cover is removed. Stepper motor B starts to drive the suction cup shaft to drive the suction cup to turn to the pickup wheel and roll the paper assembly. After turning a certain angle, stepper motor B stops rotating. The edge of the adsorbed file cover paper is facing the gap between the pickup wheel and the roller shaft. The vacuum pump stops, and at the same time, stepper motor C starts to drive the pickup wheel shaft to drive the roller shaft to rotate and roll out the file cover. After the paper passing signal photoelectric sensor B senses the paper passing, it sends out a paper removal completion signal, the stepper motor C stops rotating, the stepper motor B starts, and the vacuum suction cup returns to the starting zero position. The suction cup zero position photoelectric sensor B sends out an in-position signal, the control system sends a paper feed command, the paper feeding mechanism rises, presses the file cover tightly, and starts printing the next page of the file cover.

[0021] A file cover filling printer working method is as follows:

[0022] Before starting printing, the file covers to be printed will be manually loaded into the paper storage bin, and the number of files put in must be lower than the upper edge of the paper storage bin. After paper loading is completed, printing is started, and the paper feeding mechanism lifts the file covers to be filled in and printed in the paper storage bin to the printing position, presses the file covers, and the writing and printing mechanism starts to print the content to be filled in. After filling and printing are completed, the paper removal mechanism is started to remove the printed file covers and enter the next printing process.

[0023] This printer works differently from traditional printers. Traditional printers work in a single-sheet feeding mode. When printing, the print head moves in the X-axis direction and the paper moves in the Y-axis direction. The pickup wheel is always involved in the printing process. The pickup wheel rotates frequently and is easily worn. When the pickup wheel is worn, it affects the normal movement of the paper in the Y-axis direction, causing printing quality problems such as overlapping and blurred characters.

[0024] The working mode of the printer for filling out the archive cover is: the paper feeding method is to feed the paper from bottom to top as a whole. When printing, the paper is fixed and the print head moves in the three directions of X, Y, and Z. After printing, the paper is sucked and extracted and sent to the rubbing wheel paper rolling mechanism to roll the paper out. The rubbing wheel does not participate in the printing process, which reduces the wear of the rubbing wheel. Even if the rubbing wheel is worn, it will not affect the printing quality. There are two types of print heads, one is an inkjet print head, and the other is a writing pen writing method, which can be configured according to different needs.

[0025] Advantages of a file cover filling printer:

[0026] The invention of the archive cover printer has solved the problem of filling out archive covers that has troubled archive management departments for many years. In the past, filling out archive covers manually was labor-intensive and inefficient. When printing with an ordinary printer, the pickup roller wears out quickly and needs to be replaced frequently, which is time-consuming and labor-intensive and affects normal work. The archive cover printer has a simple structure, reliable operation, and is easy to use. It does not need to replace the pickup roller frequently, which reduces the workload and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

After paper loading is completed, printing is started, and the paper feeding mechanism lifts the file covers to be filled in and printed in the paper storage bin to the printing position, presses the file covers, and the writing and printing mechanism starts to print the content to be filled in. After filling and printing are completed, the paper removal mechanism is started to remove the printed file covers and enter the next printing process.

[0052] This printer works differently from traditional printers. Traditional printers work in a single-sheet feeding mode. When printing, the print head moves in the X-axis direction and the paper moves in the Y-axis direction. The pickup wheel is always involved in the printing process. The pickup wheel rotates frequently and is easily worn. When the pickup wheel is worn, it affects the normal movement of the paper in the Y-axis direction, causing printing quality problems such as overlapping and blurred characters.

[0053] The working mode of the printer for filling out the archive cover is: the paper feeding method is to feed the paper from bottom to top as a whole. When printing, the paper is fixed and the print head moves in the three directions of X, Y, and Z. After printing, the paper is sucked and extracted and sent to the rubbing wheel paper rolling mechanism to roll the paper out. The rubbing wheel does not participate in the printing process, which reduces the wear of the rubbing wheel. Even if the rubbing wheel is worn, it will not affect the printing quality. There are two types of print heads, one is an inkjet print head, and the other is a writing pen writing method, which can be configured according to different needs.
