Description

Technical Field

[0001] This invention relates to the field of printing control technology, and in particular to an intelligent printing control device with automatic switching of stamped documents. Background Technology

[0002] With the continuous development of the machinery industry, more and more manual operations are being mechanized. Seal control devices can replace manual stamping. Seal control devices are widely used as office equipment and are used very frequently, especially in the financial industry, such as banks and tax authorities. One of the publications, CN108382084A, discloses a printing and stamping control device, including a printer and a control unit. The printer has a transmission mechanism at its paper output port. The control unit includes a chassis containing a stamping mechanism and a paper pressing mechanism at the bottom. The transmission mechanism is connected to the paper pressing mechanism. The transmission mechanism includes a swing pressing shaft, a drive shaft, and a cam. The drive shaft is connected to the swing pressing shaft via the cam. The stamping mechanism includes a stamp body and a stamping rotation frame. The paper pressing mechanism includes a paperboard feeder, a pressing arm, and a sealing strip. The pressing arm and the sealing strip... A compression spring is installed between the compression arms, and a spring retaining sleeve is provided on the compression arm to hold the compression spring. The compression arm is connected to the compression spring clamp. The two ends of the seal strip are fixed in the fixed seat through a fixed rotating shaft. This structure allows the seal body to rotate 360° and provides a certain angle when stamping, making it easy to stamp on paper of any height. However, it also has some shortcomings. It cannot achieve high-precision control of the seal and its stamping operation through a unified combination of hardware and software, resulting in poor intelligent precision of the equipment. To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0003] The purpose of this invention is to: divide the annular thin-film sensor into pressing lines at equal intervals using a zone division unit and multiple limiting slide bars; then align the pressing lines with the corresponding stamps on the limiting slide bars; and extend a preset distance to both sides of the pressing lines to form a pre-pressing zone. An information matching unit receives data and matches it with a virtual positioning ring, sending the matching result to the execution control unit. The execution control unit receives the matching result and controls the stamping positioning component and its related parts to operate. Through the unified combination of the above hardware and software, efficient and accurate stamping operation is achieved, improving the intelligence of the stamping device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent printing control device with automatic switching of stamped documents includes a housing. Inside the housing are a printing system and a feeding mechanism, adapted to the printing system. A manual feeding plate and an output plate are symmetrically arranged at the outer end of the housing, adapted to the feeding mechanism. A transmission belt is located inside the housing, with both ends facing the output plate and the feeding mechanism. A stamp positioning component is located above the transmission belt, and a pressure plate abuts against the transmission belt. The pressure plate and the stamp positioning component are on the same central axis. A switching motor is driven through the stamp positioning component, which is driven through a horizontal drive component. The stamp positioning component is also electrically connected to a control panel, which is installed at the outer end of the housing and electrically connected to the transmission belt, the feeding mechanism, the stamp positioning component, the switching motor, and the horizontal drive component.

[0005] Furthermore, the stamping positioning assembly includes a positioning box, the center of the top surface of the positioning box is fixedly connected to the output shaft of the switching motor, a positioning rotating rod is rotatably provided inside the positioning box, a positioning sleeve is fixedly fitted on the outer end of the positioning rotating rod, a positioning pressing rod is fixedly connected to the outer end of the positioning sleeve, and the end of the positioning pressing rod away from the positioning sleeve slides against the inside of the positioning box, and a positioning protrusion is fixedly connected to the bottom surface of the positioning pressing rod, the positioning protrusion abuts against an annular thin film sensor, the annular thin film sensor is gapped on the outer end of the positioning rotating rod, and the annular thin film sensor is fixedly installed on the bottom plate of the positioning box; A plurality of limiting slide rods are movably abutted against the bottom surface of one of the positioning extrusion rods. The limiting slide rods are arranged in a circular array with the center of the positioning rotating rod as the center. One end of the limiting slide rod slides through the bottom wall of the positioning box to extend to its outside and is fixedly connected to a limiting slider. The outer end of the limiting slider slides against a limiting cylinder sleeve. The limiting cylinder sleeve is fixedly set on the bottom surface of the positioning box. One end of the limiting slide rod slides through the bottom wall of the limiting cylinder sleeve to extend to its outside and is fixedly connected to a stamp. A return spring is sleeved on the outer end of the limiting slide rod. The return spring is set inside the limiting cylinder sleeve, and the two ends of the return spring abut against the bottom wall of the limiting cylinder sleeve and the bottom surface of the limiting slider, respectively. A positioning motor is fixedly set at the center of the bottom surface of the positioning box. One end of the positioning rotating rod rotates through the bottom wall of the positioning box to extend to its outside and is fixedly connected to the output shaft of the positioning motor.

[0006] Furthermore, the positioning protrusion has an arc shape, and the other end of the limiting slide rod has an arc shape.

[0007] Furthermore, the control panel is equipped with a display screen, a start button, a running light, and a warning light; support legs are provided at the four corners of the bottom surface of the housing.

[0008] Furthermore, the control panel includes a zone division unit, a data storage unit, an information matching unit, and an execution control unit.

[0009] Furthermore, the zone division unit divides the annular thin-film sensor into pressing lines at equal intervals based on multiple limiting slide bars, then aligns the pressing lines with the stamps corresponding to the limiting slide bars, and extends a preset distance to both sides of the pressing lines to form a pre-pressing area; the above data is also integrated to construct a virtual positioning ring; and the virtual positioning ring is sent to the data storage unit for storage.

[0010] Furthermore, the information matching unit is used to receive data and match it with the virtual positioning ring in the data storage unit, and send the matching result to the execution control unit.

[0011] Furthermore, the execution control unit is used to receive the matching results and control the operation of the components.

[0012] The working method of this intelligent seal control device, which automatically switches between stamped documents, is as follows: Step 1: The zone division unit divides the annular thin film sensor into pressing lines at equal intervals according to multiple limiting slide bars. Then, the pressing lines are matched with the stamps corresponding to the limiting slide bars, and a pre-pressing area is formed by extending a preset distance to both sides of the pressing lines as the center. The above data is then integrated to construct a virtual positioning ring. The virtual positioning ring is then sent to the data storage unit, which receives and stores the virtual positioning ring. Step two: After the staff selects the stamp and corresponding stamp quantity on the display screen, the document to be stamped is pushed onto the conveyor belt by the feeding mechanism. When the document to be stamped is directly below the stamp positioning component, the selected stamp and corresponding stamp quantity are sent to the information matching unit. After receiving the stamp type and corresponding stamp quantity, the information matching unit extracts the virtual positioning ring stored in the data storage unit, matches the stamp with the virtual positioning ring, and generates a control action command; it also sends the control action command to the execution control unit. Step 3: After receiving the control action command, the execution control unit immediately switches the motor to work and drives the stamp positioning component to rotate a certain angle so that the text direction of the stamp is consistent with the text direction of the document to be stamped. Then, it controls the output shaft of the positioning motor to rotate and indirectly drives the positioning protrusion to slide in a circle on the top surface of the annular film sensor and the center of the positioning extrusion rod. During the process of the positioning protrusion sliding in a circle on the top surface of the annular film sensor and the center of the positioning extrusion rod, the information matching unit collects the pressure information of the positioning protrusion to the annular film sensor, and then extracts the virtual positioning ring in the data storage unit. The movement point of the positioning protrusion is displayed at the virtual positioning ring by the change of pressure information until the movement point of the positioning protrusion moves to the pre-pressure area corresponding to the selected stamp. Step four: When the moving point is in the pre-pressing zone matched by the selected virtual positioning ring, control the positioning extrusion rod to rotate by a preset arc. First, indirectly control the positioning extrusion rod to gradually approach the pressing line, and cause the limiting slide bar that abuts against it to gradually move downward. When the limiting slide bar moves downward, it drives the stamp and limiting slider fixed to it to move downward. After the stamp moves downward, it presses onto the document to be stamped. At the same time, after the limiting slider moves downward, it compresses the return spring in the limiting cylinder sleeve to contract. Then, the positioning extrusion rod gradually moves away from the pressing line. The reverse force of the contracted return spring acts on the limiting slider, causing the limiting slider to move upward. After the limiting slider moves upward, it drives the limiting slide bar fixed to it to return to its position, thus completing one precise stamping. At the same time, control the feeding mechanism to feed and the conveyor belt to transport the document to be stamped after precise stamping. At the same time, control the positioning extrusion rod to reciprocate within the pre-pressing zone by a preset arc, thus achieving precise and repeated stamping.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This invention divides the annular thin-film sensor into pressing lines at equal intervals using a zone division unit and multiple limiting slide bars. The pressing lines are then matched with the corresponding stamps on the limiting slide bars. A pre-pressing zone is formed by extending a preset distance outwards from the pressing lines. An information matching unit receives data and matches it with a virtual positioning ring, sending the matching result to the execution control unit. The execution control unit receives the matching result and controls the stamping positioning component and its related parts to operate. Through this unified combination of hardware and software, efficient and accurate stamping operation is achieved, improving the intelligence of the stamping device. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1:

[0017] like Figure 1-6 As shown, an intelligent printing control device with automatic switching of stamped documents includes a housing 1. Inside the housing 1, there is a printing system 2 and a feeding mechanism 4. The feeding mechanism 4 is adapted to the printing system 2. The outer end of the housing 1 is symmetrically provided with a manual feeding plate 3 and a discharge plate 8. The manual feeding plate 3 is adapted to the feeding mechanism 4. Inside the housing 1, there is a transmission belt 6. The two ends of the transmission belt 6 are directly opposite the discharge plate 8 and the feeding mechanism 4. Above the transmission belt 6, there is a stamp positioning component 5. Inside the transmission belt 6, there is a pressure plate 7. The pressure plate 7 and the stamp positioning component 5 are on the same central axis. The stamp positioning component 5 is driven by a switching motor 10. The switching motor 10 is used to drive the stamp positioning component 5 to rotate at a certain angle. The switching motor 10 is driven by a horizontal drive component 9. The horizontal drive component 9 is used to drive the switching motor 10 to move horizontally left and right. After the switching motor 10 moves horizontally left and right, it drives the stamp positioning component 5 to move horizontally left and right, thereby facilitating the filling of the stamp 507. The stamping positioning component 5 includes a positioning box 501. The center of the top surface of the positioning box 501 is fixedly connected to the output shaft of the switching motor 10. The switching motor 10 rotates quantitatively through its output shaft, thereby driving the positioning box 501 to rotate at a certain angle. A positioning rotating rod 502 is rotatably provided inside the positioning box 501. A positioning sleeve 503 is fixedly sleeved on the outer end of the positioning rotating rod 502. A positioning pressing rod 504 is fixedly connected to the outer end of the positioning sleeve 503. The end of the positioning pressing rod 504 away from the positioning sleeve 503 slides against the inside of the positioning box 501. A positioning protrusion 508 is fixedly connected to the bottom surface of the positioning pressing rod 504. The end face of the positioning protrusion 508 is arc-shaped. The arc-shaped positioning protrusion 508 reduces the friction between itself and the annular thin film sensor 509. The positioning protrusion 508 abuts against the annular thin film sensor 509. The annular thin film sensor 509 is gapped and sleeved on the outer end of the positioning rotating rod 502. The annular thin film sensor 509 is fixedly installed on the bottom plate of the positioning box 501. An annular thin-film sensor 509 is used to sense the pressing position of the positioning protrusion 508. A plurality of limiting slide rods 505 are movably abutted against the bottom surface of a positioning pressing rod 504. The limiting slide rods 505 are arranged in a circular array centered on the center of the positioning rotating rod 502. One end of each limiting slide rod 505 slides through the bottom wall of the positioning box 501, extending to its exterior and being fixedly connected to a limiting slider 511. The outer end of the limiting slider 511 slides against a limiting cylinder sleeve 506, which is fixedly mounted on the bottom surface of the positioning box 501. One end of the positioning rod 505 slides through the bottom wall of the limiting cylinder sleeve 506 and extends to its outside and is fixedly connected to the stamp 507. The outer end of the limiting slide rod 505 is fitted with a return spring 512. The return spring 512 is located inside the limiting cylinder sleeve 506, and the two ends of the return spring 512 abut against the bottom wall of the limiting cylinder sleeve 506 and the bottom surface of the limiting slider 511, respectively. A positioning motor 510 is fixedly installed at the center of the bottom surface of the positioning box 501. One end of the positioning rotating rod 502 rotates through the bottom wall of the positioning box 501 and extends to its outside and is fixedly connected to the output shaft of the positioning motor 510. The stamping positioning component 5 is also electrically connected to a control panel 11. The control panel 11 is installed on the outer end of the housing 1, and a display screen 12, a start button 13, a running light 14, and a warning light 15 are installed on the control panel 11. The display screen 12 is used to select the type of stamp 507, the start button 13 is used to start the device, the running light 14 is used to indicate that the device is in operation, and the warning light 15 is used to warn the staff. Support legs 16 are provided at the four corners of the bottom surface of the housing 1, and the support legs 16 are used to support the housing 1. Control panel 11 includes a zone division unit, a data storage unit, an information matching unit, and an execution control unit; The zone division unit divides the annular thin film sensor 509 into pressing lines at equal intervals according to multiple limiting slide bars 505, then aligns the pressing lines with the stamps 507 corresponding to the limiting slide bars 505, and extends a preset distance to both sides of the pressing lines to form a pre-pressing area; it also integrates the above data to construct a virtual positioning ring; and sends the virtual positioning ring to the data storage unit for storage. like Figure 4 As shown, the sensing ring surface of the annular thin film sensor 509 is divided into pressing lines at equal intervals with the central axis of the limiting slide bar 505 as the center. When pressing the lines, the pressing force between the positioning extrusion rod 504 and the limiting slide bar 505 is the greatest, and the stamping efficiency is the best. The information matching unit is used to receive data and match it with the virtual positioning ring in the data storage unit, and send the matching result to the execution control unit. The execution control unit is used to receive the matching results and control the operation of the components; The working process and principle of this invention are as follows: Step 1: The zone division unit divides the annular thin film sensor 509 into pressing lines at equal intervals according to multiple limiting slide bars 505. Then, the pressing lines are matched with the stamps 507 corresponding to the limiting slide bars 505, and a pre-pressing area is formed by extending a preset distance to both sides of the pressing lines as the center. The above data is also integrated to construct a virtual positioning ring. The virtual positioning ring is then sent to the data storage unit for storage. Step two: The printing system 2 prints the document to be stamped or the printed document is placed on the manual feeding plate 3. Then, the feeding mechanism 4 pushes the document to be stamped onto the conveyor belt 6. When the document to be stamped is directly below the stamping positioning component 5, the operator selects the stamp 507 and the corresponding stamping quantity through the display screen 12 and sends it to the information matching unit. After receiving the type of stamp 507 and the corresponding stamping quantity, the information matching unit extracts the virtual positioning ring stored in the data storage unit, matches the stamp 507 with the virtual positioning ring, and generates a control action command. The control action command is also sent to the execution control unit. Step 3: After receiving the control action command, the execution control unit immediately switches the operation of motor 10 and drives the stamp positioning component 5 to rotate a certain angle to ensure that the text direction of the stamp 507 is consistent with the text direction of the document to be stamped. Then, it controls the output shaft of the positioning motor 510 to rotate. After the output shaft of the positioning motor 510 rotates, it drives the positioning squeezing rod 504 fixed to it to rotate through the positioning sleeve 503. After the positioning squeezing rod 504 rotates, it drives the positioning protrusion 508 fixed to it to rotate on the top surface of the annular thin film sensor 509 and to rotate around the center of the positioning squeezing rod 504. During the circumferential sliding of the positioning protrusion 508 on the top surface of the annular thin film sensor 509 with the center of the positioning extrusion rod 504, the information matching unit collects the pressure information exerted by the positioning protrusion 508 on the annular thin film sensor 509 and sends the pressure information to the information matching unit in real time. The information matching unit receives the information and extracts the virtual positioning ring in the data storage unit. The movement point of the positioning protrusion 508 is displayed at the virtual positioning ring by the change of pressure information until the movement point of the positioning protrusion 508 moves to the pre-pressing area corresponding to the selection stamp 507. Step four: When the moving point is in the pre-compression zone of the selected virtual positioning ring, control the positioning extrusion rod 504 to rotate by a preset arc. First, the positioning extrusion rod 504 gradually approaches the pressing line, and causes the limiting slide rod 505 that abuts against it to gradually move downward. When the limiting slide rod 505 moves downward, it drives the stamp 507 and the limiting slider 511 fixed to it to move downward. After the stamp 507 moves downward, it presses against the document to be stamped. At the same time, after the limiting slider 511 moves downward, it squeezes the return spring 512 in the limiting cylinder liner 506 to retract. The compression is then performed, and the positioning extrusion rod 504 gradually moves away from the pressing line. The reverse force of the return spring 512 after compression acts on the limiting slider 511, causing the limiting slider 511 to move upward. After the limiting slider 511 moves upward, it drives the limiting slide rod 505 fixed to it to return to its original position, thus completing one precise pressing. At the same time, the feeding mechanism 4 and the conveyor belt are controlled to feed and transport the document to be printed after precise pressing. Meanwhile, the positioning extrusion rod 504 is controlled to reciprocate within the pre-pressing area at a preset arc, thereby achieving precise and repeated pressing.

[0018] In summary, the present invention divides the annular thin-film sensor 509 into pressing lines at equal intervals using a zone division unit and multiple limiting slide bars 505. The pressing lines are then aligned with the corresponding stamps 507 on the limiting slide bars 505. A pre-pressing zone is formed by extending a preset distance from the pressing lines to both sides. An information matching unit receives data and matches it with a virtual positioning ring, sending the matching result to the execution control unit. The execution control unit receives the matching result and controls the stamping positioning component 5 and its related parts to operate. Through this unified combination of hardware and software, efficient and accurate stamping operation is achieved, improving the intelligence of the stamping device.

Then, the pressing lines are matched with the stamps (507) corresponding to the limiting slide bars (505), and a pre-pressing area is formed by extending a preset distance to both sides of the pressing lines as the center. The above data is then integrated to construct a virtual positioning ring. The virtual positioning ring is then sent to the data storage unit, which receives and stores the virtual positioning ring. Step 2: After selecting the stamp (507) and the corresponding stamp quantity through the display screen (12), the staff pushes the document to be stamped onto the conveyor belt (6) through the feeding mechanism (4). When the document to be stamped is directly below the stamp positioning component (5), the selected stamp (507) and the corresponding stamp quantity are sent to the information matching unit. After receiving the stamp (507) type and the corresponding stamp quantity, the information matching unit extracts the virtual positioning ring stored in the data storage unit, matches the stamp (507) with the virtual positioning ring, and generates a control action command; it also sends the control action command to the execution control unit. Step 3: After receiving the control action command, the execution control unit immediately switches the motor (10) to work and drives the stamp positioning component (5) to rotate a certain angle so that the text direction of the stamp (507) is consistent with the text direction of the document to be stamped. Then, the output shaft of the positioning motor (510) is controlled to rotate and indirectly drives the positioning protrusion (508) to slide in a circle on the top surface of the annular film sensor (509) and the center of the positioning extrusion rod (504). During the process of the positioning protrusion (508) sliding in a circle on the top surface of the annular film sensor (509) and the center of the positioning extrusion rod (504), the information matching unit collects the pressure information given by the positioning protrusion (508) to the annular film sensor (509), and then extracts the virtual positioning ring in the data storage unit.

First, the positioning squeezing rod (504) is indirectly controlled to gradually approach the pressing line, and the limiting slide rod (505) that abuts against it gradually moves downward. When the limiting slide rod (505) moves downward, it drives the stamp (507) and the limiting slider (511) fixed to it to move downward. After the stamp (507) moves downward, it presses onto the document to be stamped. At the same time, after the limiting slider (511) moves downward, it squeezes the return spring (506) in the limiting cylinder sleeve (506). 12) Contract, and then the positioning extrusion rod (504) gradually moves away from the pressing line. The reverse force of the return spring (512) after contraction acts on the limiting slider (511), causing the limiting slider (511) to move upward. After the limiting slider (511) moves upward, it drives the limiting slide rod (505) fixed to it to return to its original position, thereby completing one precise covering. At the same time, the feeding mechanism (4) feeds and the conveyor belt is controlled to transport the document to be printed after precise covering. At the same time, the positioning extrusion rod (504) is controlled to reciprocate within the pre-pressing area to rotate at a preset arc, thereby achieving precise repeated covering.
