Description

Technical Field

[0001] The present invention relates to the technical field of printing machines, in particular to an automatic typesetting printing machine and a method for using the same. Background Art

[0002] Large-format inkjet printers with automatic layout are specialized for high-quality, large-area color printing, widely used in advertising, murals, decorative paintings, and other fields. Their primary function is to achieve efficient and precise large-format printing output, supporting a variety of materials such as fabric, PVC, and adhesive-backed materials to meet diverse customer needs. Combining advanced inkjet technology with an automatic layout system, this machine automatically optimizes image layout, reduces manual errors, and improves production efficiency and capacity. Its structure primarily comprises a printhead system, an inking system, a platform conveyor system, a layout and control system, and a mechanical structure. The printheads utilize multi-color inkjet technology to ensure color reproduction and detailed rendering; the inking system ensures a stable ink supply; the platform conveyor system ensures smooth material movement; the control system supports automatic layout, parameter settings, and an operational interface; and the mechanical structure ensures precise and stable movement. The entire printing process includes design layout, file pre-processing, material preparation, parameter setting, automatic layout and calibration, printing, drying, and post-processing.

[0003] For example, a drying device for a printing machine and its use method disclosed in publication number CN116039241A is composed of a pre-drying mechanism, an adsorption drying mechanism and an air guide mechanism. While the printing roller continuously prints the paper and conveys it to the left, the air flow in the heat pipe is discharged along the inclined air outlet, and the surface of the paper is preheated through the heat pipe, which is convenient for accelerating the subsequent printer to dry the ink on the paper. However, the above technical solution mainly acts on the early conveying stage of the printing material of the printing machine and realizes the preheating of the printing material in the conveying stage. For long-sized and large-format printing materials (cloth, PVC, paper), the printing material is preheated during printing. After completion, it needs to be rolled up immediately. At this time, the printed surface of the printed material has not been continuously dried by hot air, and the ink has not been fully dried and solidified. Different types of inks have different fluidity and permeability. Oil-based or solvent-based inks have strong permeability. When they are not fully dried, the ink is easy to penetrate downward along the fibers or pores of the printed material, forming "blooming" or "bleeding" phenomena. At this time, a hot air blower can only be added to the discharge port of the printing press. Large-format materials (such as 5m wide) require multiple sets of hot air blowers in parallel to increase the continuous hot air drying link and extend the drying time. The equipment itself does not integrate reliable and efficient "stable conveying before reeling, drying and curing after reeling" coupling technology. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic typesetting printing machine and a method for using the same, wherein the large-format printing material to be printed is fed into the inkjet printer for continuous printing by a rotary drive unit, a multi-belt feeding and conveying mechanism, and a pneumatic thickness compensation pressing mechanism, and the wide-format bidirectional anti-deviation feeding structure reduces the horizontal deviation of the large-format printing material during the conveying process, and the serial centrifugal exhaust mechanism also receives power from the rotary drive unit, and the negative pressure air intake structure continuously generates a downward suction force on the printing material, so that the front and rear sides of the paper have a downward adhesion force before printing, and the exhaust end of the serial centrifugal exhaust mechanism continuously supplies hot air to the printed material through a heat conduction air box and promotes the drying and curing of the ink, thereby forming a "stable conveying before the reel, drying and curing after the reel" linkage scheme to solve the problems raised in the above background technology.

[0013] Preferably, the pulley drive module includes a synchronous belt transmission structure installed between the same end of two bidirectional screws and a servo motor installed on the outer wall of one side of the front double-layer conveyor frame for driving one of the bidirectional screws to rotate, and the input end of the servo motor is electrically connected to the output end of the control panel in the inkjet printer.

[0014] Preferably, the negative pressure air intake structure includes a rectangular empty shell installed inside the front double-layer conveyor frame, several flat-mouth exhaust pipes installed on the outer wall of one side of the rectangular empty shell, and an opening portion arranged at the top of the rectangular empty shell. The rectangular empty shell is located on the inner side of the conveyor belt. The series centrifugal exhaust mechanism includes a centrifugal fan installed at one end of the flat-mouth exhaust pipe away from the rectangular empty shell, a J-shaped tube installed on the air outlet at the lower end of the centrifugal fan, and a main pipe installed at the upper end of the J-shaped tube. The main pipe extends along the X-axis direction and is interconnected with the air inlet end of the heat conduction box.

[0015] Preferably, a hollow air duct connected to one end of the main pipe is installed on the outer wall of one side of the heat conduction air box, an electric heating wire is installed inside the hollow air duct, the input end of the electric heating wire is electrically connected to the output end of the control panel in the inkjet printer, a temperature sensor is installed on one side of the inside of the heat conduction air box, the output end of the temperature sensor is electrically connected to the input end of the control panel in the inkjet printer, and ventilation slots are provided on the outer wall of the other side of the heat conduction air box.

[0016] The present invention also provides a method for using an automatic typesetting and printing press, such as the automatic typesetting and printing press described above, comprising the following steps:

[0017] S101: The front end of the printing material on the external roll is pulled and passed through the pneumatic thickness compensation pressing mechanism. The operator manually flattens the material to the starting end of the multi-belt feeding conveying mechanism and the pneumatic thickness compensation pressing mechanism, and introduces the front end of the printing material into the inkjet printer. The operator controls the wide-format bidirectional anti-deviation feeding structure and the pneumatic thickness compensation pressing mechanism through the control panel on the inkjet printer. The two moving ends of the wide-format bidirectional anti-deviation feeding structure contact the front and back sides of the large-format printing material to achieve the purpose of horizontal deviation correction, and the pneumatic thickness compensation pressing mechanism adjusts according to the thickness of the material to ensure that the material is evenly compressed to prevent wrinkling or wrinkling.

[0018] S102: The inkjet printer is started to print and the rotary drive unit is supplied with driving force. At this time, the rotary drive unit is accelerated to a set speed, the multi-belt feed conveyor mechanism conveys the material at a constant speed, and the tandem centrifugal exhaust mechanism synchronously receives the torque of the rotary drive unit. The suction force of the negative pressure intake structure at the air inlet end of the tandem centrifugal exhaust mechanism increases linearly with the conveying speed, so that the large-format printed material is closely attached to the multi-belt feed conveyor mechanism throughout the entire process.

[0019] S103: When large-format printed materials are printed and leave the printing area of ​​the inkjet printer, the outlet end of the tandem centrifugal exhaust mechanism directs high-speed airflow into the heat-conducting air box. The heat-conducting air box evenly covers the discharge area above the inkjet printer's discharge port, forming a wide-format drying field. Staff visually inspect the initial drying effect of the printed materials. The solvent ink surface should be matte and non-sticky, and the UV ink surface should not deform under finger pressure. After confirming that the standards are met, the automatic winding program of the inkjet printer is activated.

[0020] S104: After the printing operation is completed, the pneumatic thickness compensation pressing mechanism releases the clamping force, and the rotary drive unit, the multi-belt feeding and conveying mechanism, and the serial centrifugal exhaust mechanism stop working until the temperature in the heat conduction air box drops to a safe threshold. Finally, the wide-format bidirectional anti-deviation feeding structure is reset to the initial position to complete the production cycle.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the automatic typesetting printing machine and its use method are provided with a rotary drive unit, a multi-belt feeding and conveying mechanism, a pneumatic thickness compensation pressing mechanism, a wide-format bidirectional anti-deviation feeding structure and a negative pressure air intake structure, a tandem centrifugal exhaust mechanism, a heat conduction bellows and other structures that cooperate with each other. The large-format printing material is fed into the inkjet printer by the rotary drive unit, the multi-belt feeding and conveying mechanism and the pneumatic thickness compensation pressing mechanism for continuous printing, and the wide-format bidirectional anti-deviation feeding structure reduces the horizontal deviation of the large-format printing material during the conveying process, and the tandem centrifugal exhaust mechanism also receives power from the rotary drive unit, and the negative pressure air intake structure continuously generates a downward suction force on the printing material, so that the front and rear sides of the paper have a downward adhesion force before printing, and the exhaust end of the tandem centrifugal exhaust mechanism continuously supplies hot air to the printed material through the heat conduction bellows and promotes the drying and solidification of the ink, thereby forming "stable conveying in front of the reel and steady delivery behind the reel". The rotary drive unit and multi-belt feed mechanism form a rigid conveying framework, completely eliminating the local wrinkles caused by traditional single-point traction. The pneumatic thickness compensation pressing mechanism dynamically adapts to different media (such as embossed fabric and smooth PVC), keeping the material taut and free of slack, creating an ideal surface for inkjet positioning. The wide-format bidirectional anti-drift structure locks the material's horizontal freedom like an invisible grid, and the bidirectional corrective wheel set offsets lateral displacement in real time. The triple stabilization mechanism fundamentally eliminates material jitter, snaking, or partial overhang, ensuring the sharp edges of ultra-fine text and gradient colors. The in-line centrifugal exhaust mechanism not only receives power from the rotary drive unit to ensure stable exhaust and air supply, but also applies continuous downward suction to the printed material through the negative pressure intake structure. This suction tightly adheres to the front and back edges of the material, preventing horizontal deviation or warping during conveying and printing, and ensuring accurate alignment of the printing area.

[0022] Secondly, the exhaust end of the series-type centrifugal exhaust mechanism is equipped with a heat-conducting air box, which continuously supplies hot air to the printed materials to promote the rapid drying and curing of the ink. In this process, the power of the series-type centrifugal exhaust mechanism is directly derived from the mechanical kinetic energy conversion of the conveying mechanism and the rotary drive unit. The temperature field is automatically matched with the conveying speed to avoid local under-drying caused by thermal inertia during high-speed printing. At this time, the wind force generated by the series-type centrifugal exhaust mechanism penetrates from top to bottom through the heat-conducting air box, realizing three-dimensional drying from the ink layer to the bottom layer of the medium, so that the printed material reaches a uniform and safe solidification state before being reeled up at the outlet of the inkjet printer. The difference in solvent residual rate between the layers in the roll is reduced, which fundamentally eliminates the phenomena of bleeding, smudging and back sticking.

DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] Embodiment 1, by Figures 1 to 6 The present invention includes a front double-layer conveyor frame 1, a printing inkjet printer 2 is provided on one side of the front double-layer conveyor frame 1, and a multi-belt feeding and conveying mechanism 3 for feeding the printed material into the printing inkjet printer 2 along the X-axis direction is installed inside the front double-layer conveyor frame 1, a pneumatic thickness compensation pressing mechanism 5 is installed on one side of the top of the front double-layer conveyor frame 1, and a wide-format bidirectional anti-deviation feeding structure 6 for adjusting the spacing according to the width specifications of the printed material is also installed inside the front double-layer conveyor frame 1, and a rotating drive unit 4 for driving the multi-belt feeding and conveying mechanism 3 is installed on one side of the back side of the front double-layer conveyor frame 1;

[0040] A tandem centrifugal exhaust mechanism 9 is provided on the front and rear outer walls of the front double-layer conveyor frame 1. The tandem centrifugal exhaust mechanism 9 and the multi-belt feeding and conveying mechanism 3 maintain power connection. A negative pressure air intake structure 8 connected to the air inlet end of the tandem centrifugal exhaust mechanism 9 is installed on one side of the interior of the front double-layer conveyor frame 1. A heat conduction air box 10 is installed on the top of the inkjet printer 2. The air outlet end of the heat conduction air box 10 is tilted downward. The air inlet end of the heat conduction air box 10 and the air outlet end of the tandem centrifugal exhaust mechanism 9 are connected to each other. The rotary drive unit 4, the pneumatic thickness compensation pressing mechanism 5, the wide-format bidirectional anti-deviation feeding structure 6, and the input end of the heat conduction air box 10 are all electrically connected to the output end of the control panel in the inkjet printer 2.

[0041] The rotary drive unit 4 uses a stepper motor, which is controlled by the control panel of the inkjet printer 2 to control the stepper motor to work according to the set direction, speed, angle, and response time. At this time, the output end of the stepper motor is directly related to the conveying speed of the multi-belt feeding conveyor mechanism 3, the negative pressure intensity of the negative pressure intake structure 8, and the hot air flow rate of the heat guide box 10, thereby avoiding insufficient drying energy during high-speed printing;

[0042] The multi-belt feeding conveyor mechanism 3 includes two roller support seats 301 fixed to the left outer wall of the front double-layer conveyor frame 1, a front belt roller 302 rotatably mounted between the two roller support seats 301 via a bearing, and a rear belt roller 303 rotatably mounted on the right outer wall of the front double-layer conveyor frame 1. Two conveyor belts 304 with a mirror-symmetrical structure are set between the front belt rollers 302 and the rear belt rollers 303. The driving shaft of the rotary drive unit 4 drives the front belt roller 302 between the two roller support seats 301 in the Y-axis direction to rotate through a coupling. The front belt rollers 302 and the rear belt rollers 303 drive the two conveyor belts 304 to rotate. The two conveyor belts 304 are able to disperse the pressure, increase the smoothness of the conveying of printed materials, and reduce the load on the single conveyor belt 304. The front and rear edges and the middle position of the large-format printed materials are exposed.

[0043] Square longitudinal beams 306 are fixed on both sides of the interior of the front double-layer conveyor frame 1, and a hollow triangular beam 305 is fixed on the outer wall of the front double-layer conveyor frame 1 on one side of the rear belt roller 303. The upper surfaces of the square longitudinal beams 306 and the hollow triangular beams 305 are in contact with the top wall of the conveyor belt 304. The hollow triangular beams 305 and the square longitudinal beams 306 are able to support the top of the conveyor belt 304, so that the printed materials will not sag or deform during transportation, especially ensuring the flatness of ultra-thin paper or elastic fabrics under high-speed operation.

[0044] A method for using an automatic typesetting and printing machine according to this embodiment, such as the automatic typesetting and printing machine described above, includes the following steps:

[0045] S101: The front end of the printing material on the external roll is pulled and passed through the pneumatic thickness compensation pressing mechanism 5. The operator manually flattens the material to the starting end of the multi-belt feeding and conveying mechanism 3 and the pneumatic thickness compensation pressing mechanism 5, and introduces the front end of the printing material into the inkjet printer 2. The operator controls the wide-format bidirectional anti-deviation feeding structure 6 and the pneumatic thickness compensation pressing mechanism 5 through the control panel on the inkjet printer 2 to work. The two moving ends of the wide-format bidirectional anti-deviation feeding structure 6 contact the front and rear sides of the large-format printing material to achieve the purpose of horizontal deviation correction, and the pneumatic thickness compensation pressing mechanism 5 is adjusted according to the thickness of the material to ensure that the material is evenly compressed to prevent wrinkling or wrinkling;

[0046] S102: The inkjet printer 2 is started to print and the rotary drive unit 4 is started to supply driving force. At this time, the rotary drive unit 4 is accelerated to the set speed, the multi-belt feeding and conveying mechanism 3 conveys the material at a constant speed, and the serial centrifugal exhaust mechanism 9 synchronously receives the torque of the rotary drive unit 4. The suction force at the negative pressure intake structure 8 at the air inlet end of the serial centrifugal exhaust mechanism 9 increases linearly with the conveying speed, so that the large-format printed material is closely attached to the multi-belt feeding and conveying mechanism 3 throughout the entire process;

[0047] S103: When the large-format printed material is printed and leaves the printing area of ​​the inkjet printer 2, the outlet end of the tandem centrifugal exhaust mechanism 9 directs high-speed airflow into the heat-conducting air box 10. The heat-conducting air box 10 evenly covers the discharge area above the discharge port of the inkjet printer 2, forming a wide-format drying field. The staff visually inspects the initial drying effect of the printed material. The solvent ink surface should be matte and non-sticky, and the UV ink surface should not deform after finger pressure. After confirming that the quality meets the requirements, the automatic winding process of the inkjet printer 2 is started.

[0048] S104: After the printing operation is completed, the pneumatic thickness compensation pressing mechanism 5 releases the clamping force, and the rotary drive unit 4, the multi-belt feeding and conveying mechanism 3, and the serial centrifugal exhaust mechanism 9 stop working until the temperature in the heat conduction air box 10 drops to the safety threshold, and finally resets the wide-format bidirectional anti-deviation feeding structure 6 to the initial position to complete the production cycle.

[0049] Example 2, based on Example 1, Figure 7 and Figure 8It is given that the pneumatic thickness compensation pressing mechanism 5 includes two diagonal support plates 501 fixed at the top edge position of the left side of the front double-layer conveyor frame 1, a support shaft 502 fixed between the two diagonal support plates 501, T-shaped shaft seats 503 movably mounted on the two ends of the support shaft 502 surface, and a rotating shaft 505 rotatably installed between the two T-shaped shaft seats 503, the rotating shaft 505 is located at the upper right side of the front belt roller 302, and a plurality of rubber wheels 506 are fixed on the surface of the rotating shaft 505. The flexible properties of the rubber wheels 506 can prevent mechanical damage to sensitive media by the hard pressure roller. A cylinder 507 for controlling the T-shaped shaft seat 503 to swing around the central axis of the support shaft 502 is installed on the outer wall of one side of the diagonal support plate 501, and the input end of the cylinder 507 is electrically connected to the output end of the control panel in the inkjet printer 2;

[0050] The bottom of the cylinder 507 is hinged to the outer wall of one side of the diagonal support plate 501, and a fisheye joint is fixed to the top of the piston rod of the cylinder 507. A round pin 504 is installed on the outer wall of one side of the diagonal support plate 501 and is hinged to the fisheye joint. When the conveyor belt 304 continues to convey the printing material to the inkjet printer 2, the staff adjusts the distance between the rubber wheel 506 and the upper surface of the conveyor belt 304 according to the thickness of the printing material. At this time, the cylinder 507 is controlled to work through the control panel in the inkjet printer 2, so that the top of the piston rod of the cylinder 507 drives the round pin 504 to move downward through the fisheye joint. Since the T-shaped shaft seat 503 is mounted on the support shaft 502, the round pin 504, the T-shaped shaft seat 503, the rotating shaft 505, and the rubber wheel 506 are deflected downward around the support shaft 502 to adjust the distance between the rubber wheel 506 and the conveyor belt 304 to ensure that the printing material is evenly compressed and wrinkles are reduced.

[0051] Example 3, based on Example 2, Figure 9 It is given that the wide-format bidirectional anti-deviation feeding structure 6 is located on the inner side of the conveyor belt 304. The wide-format bidirectional anti-deviation feeding structure 6 includes a support frame 601 fixed to the two ends of the interior of the front double-layer conveyor frame 1, a bidirectional screw rod 602 rotatably installed inside the support frame 601, and a nut pair 604 installed at the threaded positions at both ends of the surface of the bidirectional screw rod 602. A slide 603 that slides with the bottom of the support frame 601 is fixed on the outer wall of the nut pair 604. Two connecting rods 605 are fixed on the outer wall of one side of the slide 603. In the same X-axis direction, The ends of the four connecting rods 605 are fixed with correcting plates 606. The interior of the front double-layer conveyor frame 1 is also equipped with a pulley drive module 7 for driving the two bidirectional screw rods 602 to rotate synchronously in the same direction. The pulley drive module 7 includes a synchronous belt transmission structure 702 installed between the same ends of the two bidirectional screw rods 602 and a servo motor 701 installed on the outer wall of one side of the front double-layer conveyor frame 1 for driving one of the bidirectional screw rods 602 to rotate. The input end of the servo motor 701 is electrically connected to the output end of the control panel in the inkjet printer 2.

[0052] The servo motor 701 is controlled by the control panel of the inkjet printer 2 to work. The servo motor 701 provides rotational power to the bidirectional screw rods 602 in the two support frames 601 through the synchronous belt transmission structure 1 702. The bidirectional screw rods 602 drive the nut pairs 604 at both ends of themselves to move in opposite directions, and then the two slides 603 move closer to or away from each other in the Y-axis direction, so as to adjust the distance between the two correcting plates 606 in the Y-axis direction. Therefore, the bidirectional adjustment mechanism can be used to fine-tune the material during transportation, and at the same time effectively offset the snaking caused by the material's own stress release or airflow disturbance, ensuring that the material always maintains a horizontal and accurate inkjet printing position.

[0053] Example 4, based on Example 2, Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 It is given that the negative pressure air intake structure 8 includes a rectangular empty shell 801 installed inside the front double-layer conveyor frame 1, a plurality of flat exhaust pipes 802 installed on the outer wall of one side of the rectangular empty shell 801, and an opening 803 arranged at the top of the rectangular empty shell 801. The rectangular empty shell 801 is located on the inner side of the conveyor belt 304. The serial centrifugal exhaust mechanism 9 includes a centrifugal fan 901 installed at one end of the flat exhaust pipe 802 away from the rectangular empty shell 801, a J-shaped tube 902 installed on the air outlet at the lower end of the centrifugal fan 901, and a main pipe 903 installed at the upper end of the J-shaped tube 902. The main pipe 903 extends along the X-axis direction and is interconnected with the air inlet end of the heat conduction box 10. The multiple centrifugal fans 9 in the X-axis direction A second synchronous belt transmission structure 904 for power connection is installed between 01 and the end of the front belt roller 302. When the serial centrifugal exhaust mechanism 9 is in operation, power is transmitted between the input shaft of the centrifugal fan 901 and the end of the front belt roller 302 via the second synchronous belt transmission structure 904. Then, multiple centrifugal fans 901 on the same side receive the rotational power from the front belt roller 302 via the second synchronous belt transmission structure 904. The air collecting port of the centrifugal fan 901 sucks air through the flat exhaust pipe 802 and the rectangular empty shell 801, thereby utilizing the opening 803 at the top of the rectangular empty shell 801 to generate a uniform negative pressure field below the conveyor belt 304 and the printed material to eliminate material warping.

[0054] The second synchronous belt drive structure 904 includes a driving pulley mounted on the end of the front belt roller 302 and a driven pulley mounted on the input shaft of the centrifugal fan 901. To ensure that the centrifugal fan 901 obtains a sufficient rotational speed, the outer diameter of the driving pulley can be made much larger than that of the driven pulley to achieve the purpose of increasing transmission speed. The outer surface of the conveyor belt 304 can be provided with through holes so that the suction force generated by the opening 803 can act on the printing material.

[0055] The exhaust port of the centrifugal fan 901 sends the generated wind J-shaped pipe 902 to the main pipe 903, and the main pipe 903 sends the wind into the heat conduction box 10;

[0056] A hollow air duct 1001 is installed on the outer wall of one side of the heat conduction air box 10, which is interconnected with one end of the main pipe 903. An electric heating wire 1002 is installed inside the hollow air duct 1001. The input end of the electric heating wire 1002 is electrically connected to the output end of the control panel in the inkjet printer 2. A temperature sensor 1003 is installed on one side of the inside of the heat conduction air box 10, and the output end of the temperature sensor 1003 is electrically connected to the input end of the control panel in the inkjet printer 2. A ventilation groove 1004 is provided on the outer wall of the other side of the heat conduction air box 10. The electric heating wire 1002 heats the air in the hollow air duct 1001 and the main pipe 903, so that the heated air is sent into the heat conduction air box 10, and the temperature sensor 1003 continuously monitors the temperature in the heat conduction air box 10. At this time, the hot air is discharged through the ventilation groove 1004 on the outer wall of the heat conduction air box 10, and the hot air blows downward toward the printing material and penetrates the gaps between the material fibers, forming turbulence under the ink layer, thereby drying the ink.

[0057] When the embodiment of the present application is in use, the staff first checks whether the power supply and control system of the inkjet printer 2 are connected normally, and then checks the rotary drive unit 4 and the multi-belt feeding and conveying mechanism 3 to ensure that they are not damaged, there is no foreign matter blocking them, and that each driving part operates flexibly. Special attention should be paid to the pneumatic thickness compensation pressing mechanism 5 to confirm that its pressure adjustment is normal and can adapt to materials of different thicknesses. The wide-format bidirectional anti-deviation feeding structure 6 should also be checked and debugged to ensure that its adjustment mechanism is sensitive and firmly fastened to avoid the deviation of large-format printed materials during transportation; the head end of the printed material on the external roll is pulled and passed through the pneumatic thickness compensation pressing mechanism 5, and the operator manually flattens the material to the multi-belt feeding and conveying mechanism. The feeding mechanism 3 and the starting end of the pneumatic thickness compensation pressing mechanism 5 are used to introduce the head end of the printing material into the inkjet printer 2, and the paper pressing mechanism of the inkjet printer 2 bites the edge of the material to achieve initial tension locking; the operator controls the wide-format bidirectional anti-deviation feeding structure 6 and the pneumatic thickness compensation pressing mechanism 5 to work through the control panel on the inkjet printer 2. The two moving ends of the wide-format bidirectional anti-deviation feeding structure 6 are in contact with the front and back sides of the large-format printing material to achieve the purpose of horizontal deviation correction, and the pneumatic thickness compensation pressing mechanism 5 is adjusted according to the thickness of the material to ensure that the material is evenly compressed to prevent wrinkling or wrinkling; the staff controls the inkjet printer 2 The printing parameters, including nozzle speed, inkjet density and printing area size, are set on the panel. Then, the inkjet printer 2 is started for printing and the rotary drive unit 4 is started for driving force supply. At this time, the rotary drive unit 4 is accelerated to the set speed, the multi-belt feeding and conveying mechanism 3 conveys the material at a constant speed, and the serial centrifugal exhaust mechanism 9 synchronously receives the torque of the rotary drive unit 4. The suction force at the negative pressure air intake structure 8 at the air inlet end of the serial centrifugal exhaust mechanism 9 increases linearly with the conveying speed, so that the large-format printing material is closely attached to the multi-belt feeding and conveying mechanism 3 throughout the whole process, eliminating the suspended vibration, and in the process of the large-format printing material entering the printing area of ​​the inkjet printer 2, the pneumatic thickness compensation pressing mechanism 5 and the wide-width The bidirectional anti-deviation feeding structure 6 guides the transportation of printed materials at all times; when the large-format printed materials are printed and leave the printing area of ​​the inkjet printer 2, the outlet end of the series-type centrifugal exhaust mechanism 9 guides the high-speed airflow into the heat-conducting air box 10. The heat-conducting air box 10 evenly covers the discharge area above the discharge port of the inkjet printer 2 to form a wide-format drying field. The staff visually inspects the drying effect of the first section of the printed materials. The solvent ink surface should be matte and non-sticky, and the UV ink surface should not be deformed by finger pressure. After confirming that it meets the standards, the automatic winding program of the inkjet printer 2 is started. At this time, the winder speed of the inkjet printer 2 needs to match the rotary drive unit 4 to avoid the phenomenon of ink not drying, printing bleeding, and smudging caused by too fast winding;After the printing operation is completed, the pneumatic thickness compensation clamping mechanism 5 releases the clamping force, and the rotary drive unit 4, multi-belt feed conveyor mechanism 3, and serial centrifugal exhaust mechanism 9 stop working until the temperature in the heat conduction box 10 drops to a safe threshold. Finally, the wide-format bidirectional anti-drift feed mechanism 6 is reset to its initial position, completing the production cycle.
