Description

Technical Field

[0001] The present invention relates to the technical field of plane printing, and in particular to a control method of a printing system and an ARM mainboard. Background Art

[0002] When printing on flat surfaces of lightweight materials (such as paper, cardboard, and plastic), the friction coefficient between the lightweight material and the guide belt is very low. As the guide belt of the printing platform steps, the material position will gradually deviate. For the printing control system, the error in the calculation of the printing position needs to be controlled below a millimeter. Otherwise, the effect of the entire material will be greatly reduced. If the effect is too poor, the entire lightweight material may even be scrapped.

[0003] In the automated printing process, when lightweight materials are fed to the printing platform by a feeding machine or manually, it is impossible to locate a precise starting printing position. The printing control system needs to calculate every position of the material on the printing platform to ensure the smooth completion of the printing process. Summary of the Invention

[0013] Based on the print trigger instruction, controlling the positioning rod to lift and the rear pressure roller to fall;

[0014] When the front end of the material to be printed is close to the front pressure roller, the front pressure roller is controlled to fall based on the falling amount of the front pressure roller;

[0015] When the rear end of the material to be printed is close to the rear pressure roller, the rear pressure roller is controlled to be raised based on the advance amount of the rear pressure roller;

[0016] When the rear end of the material to be printed is close to the front pressing roller, the front pressing roller is controlled to be lifted based on the advance amount of lifting of the front pressing roller.

[0017] In an optional embodiment, the control method of the printing system further includes:

[0019] In an optional embodiment, the printing system includes the front pressure roller, the rear pressure roller, the positioning rod, the nozzle, the guide belt, the loading device and at least one fan;

[0020] Along the forward direction of the guide belt, the nozzle is arranged in front of the positioning rod, and the nozzle and the positioning rod are both arranged between the front pressure roller and the rear pressure roller; the guide belt is used to carry the material to be printed and move along the forward direction;

[0021] The fan is arranged below the guide belt.

[0022] In an optional embodiment, when the printing mode is a production mode, a rear loading method is adopted, and the loading device is controlled to place the next material to be printed on the guide belt behind the positioning rod, so that the next material to be printed is moved to the position of the positioning rod by the guide belt within a preset loading interval.

[0023] In an optional embodiment, the control method of the printing system further includes:

[0024] When the printing mode is the debugging mode, for a material to be printed:

[0025] Acquire the printing information and the printing trigger instruction;

[0026] When the rear end of the material to be printed is aligned with the front end of the positioning rod by front loading, the guide belt is controlled to move in a direction opposite to the forward direction by a preset reverse movement distance; the preset reverse movement distance is the sum of the length of the material to be printed and the width of the positioning rod;

[0035] Compared to the prior art, the control method for a printing system provided by the present invention uses a positioning rod to determine the initial position of each material to be printed, and based on the positional relationship between the actual position and the positions of the multiple control objects, controls the lifting and lowering of the multiple control objects to complete printing. Because the actual position of the material to be printed changes with the movement of the guide belt, while the positions of the multiple control objects, such as the front pressure roller, the positioning rod, and the rear pressure roller, are fixed, the distance between the actual position of the material to be printed and the positions of the multiple control objects also changes. Based on this changing positional relationship, the front pressure roller is controlled to be raised or lowered, the rear pressure roller is controlled to be raised or lowered, and the positioning rod is controlled to be raised or lowered. Firstly, each material to be printed can be positioned, thereby improving printing accuracy and thereby improving printing efficiency. Secondly, when the front pressure roller and the rear pressure roller are lowered, they can play a certain role in fixing the material to be printed, preventing the material from shifting forward or backward or left or right. Secondly, they can improve printing accuracy and thereby improve printing efficiency.

[0042] To facilitate a clear description of the technical solutions of the embodiments of the present invention, the words "first" and "second" are used in the embodiments of the present invention to distinguish between identical or similar items with substantially the same functions and effects. For example, the first threshold and the second threshold are merely used to distinguish between different thresholds and do not limit their order. Those skilled in the art will understand that the words "first" and "second" do not limit the quantity or execution order, and the words "first" and "second" do not necessarily mean different.

[0043] It should be noted that, in the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present invention should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0044] In the present invention, "at least one" means one or more, "more than one" means two or more, and "and / or" describes the association relationship between associated objects, indicating that three types of relationships can exist.

[0045] In printing scenarios with lightweight materials (such as paper, cardboard, and plastic), due to the low mass of lightweight materials and the low friction between them and the guide belt, the material position is prone to gradually deviate from the standard printing position during the printing process. The standard printing position refers to the printing position required by the user on the lightweight material. For some special printing scenarios, the error between the actual printing position of the material and the standard printing position needs to be controlled to a millimeter level or even higher accuracy, such as scenarios where multiple materials to be printed need to be matched or nested. For such scenarios with extremely high printing accuracy requirements and relatively lightweight materials to be printed, such as Figure 1 As shown, an embodiment of the present invention provides a control method for a printing system, which may include:

[0046] Step 110: Obtain printing information and a printing trigger instruction; the printing information includes at least a printing mode, positions of multiple control objects, and a moving speed of a material to be printed; the control objects include at least a front pressure roller, a positioning rod, and a rear pressure roller;

[0047] Specifically, the printing system may include: Figure 2 The front pressure roller 10, the nozzle 20, the positioning rod 30, and the rear pressure roller 40 are shown. The nozzle 20 is arranged in front of the positioning rod 30 along the forward direction of the guide belt, and the nozzle 20 and the positioning rod 30 are both arranged between the front pressure roller 10 and the rear pressure roller 40.

[0048] The printing system may further include a guide belt, the guide belt being used to carry the material to be printed and move along the advancing direction of the guide belt.

[0049] The material to be printed can be a lightweight material such as paper, carton, and plastic, for example, rectangular paper, such as a rectangular carton.

[0050] The printing system may further include a loading device for placing a material to be printed on the guide belt. Furthermore, the loading device may further place a material to be printed on the guide belt behind the positioning rod within a preset loading interval, so that the material to be printed is moved by the guide belt to the position of the positioning rod within the preset loading interval.

[0051] It can be understood that, from a top view, the projection of the front pressure roller 10 on the guide belt is a rectangle, the projection of the positioning rod 30 on the guide belt is also a rectangle, and the projection of the rear pressure roller 40 on the guide belt is also a rectangle. Therefore, the printing information can also include the front pressure roller size, the positioning rod size and the rear pressure roller size, wherein the front pressure roller size includes the front pressure roller length and the front pressure roller width, the positioning rod size includes the positioning rod length and the positioning rod width, and the rear pressure roller size includes the rear pressure roller length and the rear pressure roller width.

[0052] Therefore, the position of the control object may include the front end position and the rear end position of the control object.

[0053] Of course, the actual position of the material to be printed also includes the front and rear positions of the material to be printed. Accordingly, the printing information also includes the dimensions of the material to be printed, which may include the length and width of the material to be printed. The rear position of the material to be printed can be determined based on the front position and the dimensions of the material to be printed.

[0054] The print trigger instruction may be an instruction generated by the user clicking an instruction button such as “start printing”.

[0055] The print trigger instruction can also be automatically triggered and generate a print trigger instruction when the preset feeding interval time ends.

[0056] Step 120: When the printing mode is production mode, for each material to be printed:

[0057] Based on the print trigger instruction, the actual position of the material to be printed is obtained; the actual position is determined based on the initial position and movement speed of the material to be printed, and the initial position is determined based on the position of the positioning rod;

[0058] Production mode characterization requires printing multiple materials to be printed. In a specific printing scenario, once printing begins, the guide belt will move along the belt's forward direction at a preset speed, carrying the materials to be printed. Therefore, the speed of the guide belt is the same as the speed of the materials to be printed.

[0059] The positioning rod is located behind the printhead. When it's lowered, it blocks the advance of the printed material. In this scenario, the front end of the printed material is aligned with the rear end of the rod. Because of this, the positioning rod also serves as the initial positioning of the printed material. As mentioned above, the initial position is determined based on the position of the positioning rod. When the initial position and speed of the printed material are known, the actual position of the printed material relative to the initial position can be calculated.

[0060] Step 130: Based on the positional relationship between the actual position and the positions of the multiple controlled objects, the lifting and lowering actions of the multiple controlled objects are controlled to complete printing.

[0061] From the above content, it can be seen that since the actual position of the material to be printed changes with the movement of the guide belt, and the positions of multiple control objects such as the front pressure roller, the positioning rod and the rear pressure roller are fixed, the distance between the actual position of the material to be printed and the positions of the multiple control objects is also changing. Based on this changing positional relationship, the front pressure roller is controlled to be lifted or lowered, the rear pressure roller is controlled to be lifted or lowered, and the positioning rod is controlled to be lifted or lowered. First, each material to be printed can be positioned, thereby improving the printing accuracy from the first level, thereby improving the printing efficiency. Second, when the front pressure roller and the rear pressure roller fall, they can play a certain fixing role on the material to be printed, preventing the material to be printed from shifting forward and backward or shifting left and right, thereby improving the printing accuracy from the second level, thereby improving the printing efficiency.

[0062] Optionally, the printing information further includes a front pressure roller drop amount, a front pressure roller lift advance amount, and a rear pressure roller lift advance amount; the actual position includes a front end position of the material to be printed and a rear end position of the material to be printed;

[0063] Controlling the rise and fall of the controlled object based on the positional relationship between the actual position and the positions of the multiple controlled objects in step 130 may specifically include:

[0064] (1) Based on the print trigger command, control the positioning rod to lift and the rear pressure roller to fall;

[0065] (2) When the front end of the material to be printed is close to the front pressure roller, the front pressure roller is controlled to fall based on the amount of the front pressure roller falling;

[0066] (3) When the rear end of the material to be printed is close to the rear pressure roller, the rear pressure roller is controlled to be lifted based on the advance amount of the rear pressure roller;

[0067] (4) When the rear end of the material to be printed is close to the front pressure roller, the front pressure roller is controlled to be lifted based on the advance amount of the front pressure roller.

[0068] In step (1), as mentioned above, for the first material to be printed in the batch of materials to be printed, the printing trigger instruction may be triggered by the user pressing the "Print Start" button; for the other materials to be printed in the batch of materials to be printed, the printing trigger instruction may be triggered when the preset loading interval expires. The generation of the printing trigger instruction may indicate that the material to be printed has been aligned with the positioning rod in advance. Optionally, the alignment of the material to be printed with the positioning rod may be further understood as the front end position of the material to be printed and the rear end position of the positioning rod being coincident.

[0069] When the printing system receives a print trigger command, it raises the positioning lever and lowers the rear pressure roller. This raises the positioning lever, removing any obstruction to the material being printed. Once the positioning lever is raised, the material can move at a uniform speed along the guide belt. Lowering the rear pressure roller stabilizes the material to a certain degree, preventing relative movement of the material relative to the guide belt during movement. This ensures a more secure fit and more accurate placement of the printed image.

[0070] After step (1), the method further includes: when the distance between the front end position of the material to be printed and the position of the nozzle reaches a preset printing distance, controlling the nozzle to print.

[0071] Optionally, the preset printing distance may be zero. In this case, the preset printing distance indicates that the front end position of the material to be printed coincides with the front end position of the nozzle (eg, the position of the first row of nozzle holes).

[0072] Optionally, the preset printing distance can be greater than zero. In this case, the preset printing distance represents that the front end position of the material to be printed exceeds the front end position of the nozzle by a certain pattern distance. The pattern distance here refers to the set distance between the front end position of the image and the front end position of the material to be printed.

[0073] In step (2), the front roller drop is a distance indicating that the material to be printed has entered the front roller area. Alternatively, the front roller drop can indicate the distance between the front end of the printing material and the rear end of the front roller.

[0074] Then, the steps may specifically include: when the front end of the material to be printed is close to the front pressure roller and the distance between the front end of the material to be printed and the rear end of the front pressure roller is greater than or equal to the first distance, controlling the front pressure roller to drop.

[0075] For example, since the material to be printed keeps moving forward, when the front end of the material to be printed is close to the front pressure roller and the distance between the front end of the material to be printed and the rear end of the front pressure roller is greater than 1CM, the front pressure roller is controlled to fall.

[0076] Similar to the function of the lowered rear pressure roller, the lowered front pressure roller also serves to stabilize the printed material to a certain extent, preventing it from moving relative to the guide belt during movement. This, in turn, allows the printed material to adhere more firmly to the guide belt, allowing the printed image to be printed more accurately. Of course, if both the front and rear pressure rollers are lowered, the printed material is most secure.

[0077] In step (3), the rear roller lift advance is a distance indicating that the material to be printed is about to leave the rear roller area. The rear roller lift advance is the distance between the rear end position of the printing material and the rear end position of the rear roller. Specifically, the rear roller lift advance is the distance between the rear end position of the material to be printed and the rear end position of the rear roller when the rear end position of the material to be printed is close to the rear end position of the rear roller.

[0078] Therefore, step (3) may specifically include: when the rear end of the material to be printed is close to the rear pressure roller and the distance between the rear end of the material to be printed and the rear end of the rear pressure roller is greater than or equal to a second distance, controlling the rear pressure roller to lift. The second distance is greater than 0.

[0079] Similarly, the front roller lift lead is also a distance, indicating that the printed material is about to leave the front roller area. The front roller lift lead represents the distance between the rear end of the printed material and the rear end of the front roller. Specifically, the front roller lift lead is the distance between the rear end of the printed material and the rear end of the front roller when the rear end of the printed material is close to the rear end of the front roller.

[0080] Therefore, step (4) may specifically include: when the rear end of the material to be printed is close to the front pressure roller and the distance between the rear end of the material to be printed and the rear end of the front pressure roller is greater than or equal to a third distance, controlling the front pressure roller to lift. The third distance is greater than 0.

[0081] During the printing process, when the actual position of the material to be printed leaves the positioning rod area, the positioning rod is controlled to drop, and the loading mechanism is controlled to begin placing the next material to be printed on the guide belt. Within the preset loading interval, the next material to be printed can reach the positioning rod position and be intercepted by the positioning rod. When the preset loading interval expires, the print trigger command is triggered, the positioning rod is raised, and the rear pressure roller drops. Therefore, the preset loading interval can also represent the time from the positioning rod dropping to the lifting of the positioning rod after printing a material to be printed during a continuous printing operation.

[0082] When the preset loading interval expires, the printing system receives a print trigger command and controls the actions of multiple control objects according to the control method used during the printing of the previous material to be printed, and starts printing the new material to be printed until all the materials to be printed are printed.

[0083] Because the material to be printed is generally made of a lightweight, soft material of a certain thickness, its low coefficient of friction can cause the material to shift when moving on the guide belt. Using front and rear pressure rollers to secure the material can effectively prevent this. However, as the material is about to leave the pressure rollers, the edges of the material are easily flattened by the pressure rollers, and the front or rear pressure rollers can exert a slight thrust on the material, causing the material to shift, thereby resulting in print position deviation. Therefore, in an embodiment of the present invention, setting a lead time for the front and rear pressure rollers to lift up can prevent the front or rear pressure rollers from crushing the end of the material to be printed or causing it to shift, ultimately improving printing accuracy and efficiency.

[0084] It is understandable that in the production mode, when all the materials to be printed have been printed, the front pressure roller, the positioning rod and the rear pressure roller are all controlled to be raised.

[0085] It should be emphasized that when the printing mode is the production mode, the rear loading method is adopted, and the loading device is controlled to place the next material to be printed on the guide belt behind the positioning rod, so that the next material to be printed is moved to the position of the positioning rod by the guide belt within the preset loading interval.

[0086] The rear loading mentioned here is different from the front loading described below.

[0087] Optionally, the control method of the printing system further includes:

[0088] When the print mode is debug mode, for a material to be printed:

[0089] Get printing information and printing trigger instructions;

[0090] When the rear end of the material to be printed is aligned with the front end of the positioning rod by the front loading method, the guide belt is controlled to move in a direction opposite to the forward direction by a preset reverse movement distance; the preset reverse movement distance is the sum of the length of the material to be printed and the width of the positioning rod;

[0091] When the guide belt moves the preset reverse moving distance and the positioning rod falls, the guide belt is controlled to move in the forward direction;

[0092] Based on the print trigger instruction, the actual position of the material to be printed is obtained; the actual position is determined based on the initial position and movement speed of the material to be printed, and the initial position is determined based on the position of the positioning rod; the print trigger instruction in the debug mode is triggered by the user manually dropping the positioning rod.

[0093] In an optional manner, before printing the first material to be printed, a positioning rod can be manually lowered to position the material.

[0094] Based on the positional relationship between the actual position and the positions of the multiple controlled objects, the rising and falling actions of the multiple controlled objects are controlled to complete printing and obtain a printed pattern.

[0095] In the debugging mode, when the positioning rod falls, the subsequent control method is the same as the control method in the production mode.

[0096] It should be noted that in the debugging mode, only one material to be printed is printed at a time. According to the print pattern obtained after printing, the front pressure roller lifting advance amount and the rear pressure roller lifting advance amount are adjusted and updated, and the parameters such as the front pressure roller drop amount are adjusted and updated.

[0097] Debug mode uses front loading because in some real-world printing scenarios, the printing equipment in the printing system is large, and workers need to walk from the front to the back of the printing equipment, which is about ten meters. Because the computer and control buttons are located at the front of the printing equipment, and the operator must be present during debug mode, to avoid operator trouble, the adjustment mode often uses front loading to improve printing convenience. Rear loading is suitable for production models that print large quantities of materials, and the materials to be printed can be continuously delivered to the printing area from the rear automatic loading device.

[0098] Optionally, the control method of the printing system further includes:

[0099] Based on the front pressure roller lifting instruction, the front pressure roller is controlled to be lifted; the front pressure roller lifting instruction is generated based on the user's manual lifting action of the front pressure roller;

[0100] Based on the front pressure roller drop instruction, the front pressure roller is controlled to drop; the front pressure roller drop instruction is generated based on the user's manual action of dropping the front pressure roller;

[0101] Control the print head to print based on the print instruction; the print instruction is generated based on the user manually clicking the print button;

[0102] Based on the rear pressure roller lifting instruction, the rear pressure roller is controlled to be lifted; the rear pressure roller lifting instruction is generated based on the user's manual lifting action of the rear pressure roller;

[0103] Based on the rear pressure roller drop instruction, the rear pressure roller is controlled to drop; the rear pressure roller drop instruction is generated based on the user's manual action of dropping the rear pressure roller;

[0104] Based on the positioning rod lifting instruction, the positioning rod is controlled to be lifted; the positioning rod lifting instruction is generated based on the user's manual lifting action of the positioning rod;

[0105] Based on the positioning rod drop instruction, the positioning rod is controlled to drop; the positioning rod drop instruction is generated based on the user's manual action of dropping the positioning rod.

[0106] It should be emphasized that the rear pressure roller can be triggered manually or automatically (time) in two ways;

[0107] The lowering of the rear pressure roller signals the start of printing. Manual control means manually lowering the rear pressure roller to press the material to be printed, and the positioning rod automatically raises. Automatic control means that material can be loaded within the preset loading interval. When the time expires, the rear pressure roller automatically lowers, the positioning rod raises, and printing begins. Manual control of the rear pressure roller is used for test prints in debugging mode or for manual feeding in situations where an automatic feeder is not available. Automatic control of the rear pressure roller allows automatic feeding of the material using a loading device, achieving full automation of the entire printing process.

[0108] Aligning the material to the positioning rod can be done manually or automatically (by force).

[0109] When loading the materials to be printed, the front end of the first material to be printed must be manually aligned with the positioning rod before printing can begin. However, in production mode, the second and third materials to be printed do not need to be manually aligned. Simply place the materials to be printed on the guide belt within the preset loading interval, and the materials to be printed will automatically align with the positioning rod as the guide belt moves.

[0110] From the above content, it can be seen that the front pressure roller, rear pressure roller and positioning rod can all be manually controlled to improve printing convenience.

[0111] Optionally, the printing information also includes the material type, the control method of the printing system, and:

[0112] Based on the fan start instruction, the fan is controlled to start and the material to be printed is adsorbed on the guide belt.

[0113] Furthermore, the control method further includes:

[0114] Determine the fan operating parameters based on the material type;

[0115] Control the fan speed based on the fan operating parameters.

[0116] It should be noted that the adsorption force is initially input by the user, and the adsorption force and material parameters are stored in correspondence. Due to the diversity of materials to be printed, the weight of different materials to be printed, and the friction coefficient with the guide belt are different, it is necessary to adjust the adsorption force of the material to be printed by adjusting the adsorption force. In scenarios where printing accuracy is extremely high and the materials to be printed are relatively light, the printing accuracy is further improved, ensuring that the final printing accuracy falls within the range required by the user. The corresponding adjusted material parameters can be stored in FLash to prevent the adjusted parameters from being lost due to power outage and restart.

[0117] In an optional implementation, the control method of the printing system is implemented based on a Linux system environment; the Linux system is an open source system.

[0118] Because the PC side of a printing system typically processes a large amount of data, the control methods for peripheral devices can be stored on the ARM motherboard. Compared to Windows systems, Linux systems are more stable, faster, and consume fewer resources in the embedded field, so ARM motherboards often use Linux. Storing the control methods for the printing system on the ARM motherboard and having it execute them avoids frequent large amounts of data transmission between the PC and the motherboard, reducing data transmission pressure. It also shortens the transmission path for the control method data, improving printing efficiency.

[0119] Specifically, the control method of the printing system is implemented based on the printing control program in the Linux system environment, and the functional actions are directly controlled by the ARM motherboard, which is not applicable to the Windows system environment.

[0120] A control method for implementing a printing system based on a Linux system environment has the following advantages: 1) Since the Linux system is an open source system, users can freely obtain, use and modify the source code, and have a high degree of freedom in function implementation; 2) The Linux system is a highly portable operating system that can run on a variety of different hardware platforms; 3) The Linux system is highly customizable, and the minimum size of a trimmed Linux kernel can be less than 150KB, and it can be customized based on resource constraints in the embedded field; 4) Compared with other operating systems, the Linux system runs more stably and faster in the embedded field and occupies fewer resources.

[0121] In a specific embodiment, the control method of the control system is described by moving a material to be printed in a production mode or a debugging mode:

[0122] Starting from the initial position of the material to be printed, when the real-time movement distance is a first movement distance, the printhead is controlled to print; the first movement distance represents that when the front end of the material to be printed leaves the front end position of the printhead, the distance between the front end position of the material to be printed and the front end position of the printhead is a first preset distance; the first preset distance is greater than or equal to zero; the real-time movement distance is determined based on the initial position; the initial position can be set to 0, and the actual movement distance of the material to be printed can be determined based on the movement speed and the initial position;

[0123] When the real-time moving distance is the second moving distance, the rear pressure roller is controlled to be raised; the second moving distance indicates that when the rear end position of the material to be printed is close to the rear end position of the rear pressure roller, the distance between the rear end position of the material to be printed and the rear end position of the rear pressure roller is a second preset distance; the second preset distance is greater than zero;

[0124] When the real-time moving distance is the third moving distance, the front pressure roller is controlled to fall; the third moving distance indicates that the front end position of the to-be-printed material coincides with the rear end position of the front pressure roller;

[0125] When the real-time moving distance is a fourth moving distance, the positioning rod is controlled to fall; the fourth moving distance indicates that the rear end position of the to-be-printed material and the front end position of the positioning rod coincide with each other;

[0126] When the real-time moving distance is the fifth moving distance, the front pressure roller is controlled to lift; the fifth moving distance indicates that when the rear end position of the material to be printed is close to the rear end position of the front pressure roller, the distance between the rear end position of the material to be printed and the rear end position of the front pressure roller is the third preset distance; the third preset distance is greater than 0; the first moving distance is less than the second moving distance; the second moving distance is less than the third moving distance, and the third moving distance is less than the fourth moving distance; the fourth moving distance is less than the fifth moving distance.

[0127] Combine Figure 3 , briefly describe the control method of the control system.

[0128] like Figure 3 As shown, for the first material, manually lower the positioning rod, wait for a certain period of time, and then load the material manually or by a feeding machine;

[0129] Control the rear pressure roller to drop and the positioning rod to lift, and the guide belt steps to send the material to the printing position;

[0130] When the material leaves the printing position under the stepping of the guide belt, the positioning rod is controlled to fall;

[0131] When the material leaves the rear pressing roller area under the stepping of the guide belt, the rear pressing roller is controlled to lift;

[0132] When the material reaches the front pressing roller area under the stepping of the guide belt, the front pressing roller is controlled to fall and fix the material;

[0133] When the material leaves the front pressing roller area under the stepping of the guide belt, the front pressing roller is controlled to lift;

[0134] The first material printing is completed;

[0135] Within a certain period of time after the positioning rod falls, the second material is fed to the position of the positioning rod by a feeding machine or manually;

[0136] After a certain period of time, the rear pressure roller automatically drops down, the positioning rod is lifted, and the guide belt steps forward to send the material to the printing position;

[0137] The front and rear pressure rollers repeat the action of the first material in the printing process;

[0138] After all materials are printed, the front pressure roller, rear pressure roller and positioning rod remain raised.

[0139] Printing ends.

[0140] In an optional embodiment, the rear pressure roller and the front pressure roller are both cylindrical. The upper surface of the guide belt can be provided with grooves perpendicular to the direction of movement of the guide belt, and the side surface of the rear pressure roller is also provided with grooves in the axial direction, so as to achieve increased friction with the material to be printed. The rear pressure roller can be set to rotate axially, the rotation speed of the rear pressure roller is the same as the movement speed of the guide belt, and the width of the grooves on the surface of the guide belt and the grooves on the side surface of the rear pressure roller are the same, so as to avoid unnecessary deformation of the material to be printed due to unequal friction on both sides of the material to be printed. The front pressure roller can also be set to rotate axially, and the cylindrical radius of the front pressure roller and the cylindrical radius of the rear pressure roller can be the same or different. When the cylindrical radius of the front pressure roller and the cylindrical radius of the rear pressure roller are the same, the rotation speed of the front pressure roller can also be the same as the moving speed of the guide belt, the width of the groove on the guide belt surface and the groove on the side surface of the front pressure roller are the same, and the height of the lowest point of the cylindrical side surface of the front pressure roller when the front pressure roller falls can be slightly higher than the height of the lowest point of the cylindrical side surface when the rear pressure roller falls. This avoids unnecessary deformation of the material to be printed due to mechanical errors in the dimensions of the front and rear pressure rollers, or wrinkles on the surface of the material to be printed during movement, thereby reducing print quality. When the cylindrical radius of the front pressure roller and the cylindrical radius of the rear pressure roller are different, the front pressure roller can be configured to have a smooth side surface, and the height of the lowest point of the cylindrical side surface of the front pressure roller when the front pressure roller falls can be slightly higher than the height of the lowest point of the cylindrical side surface when the rear pressure roller falls. This avoids unnecessary deformation of the material to be printed due to the different cylindrical radius of the front pressure roller and the rear pressure roller, or wrinkles on the surface of the material to be printed during movement, thereby reducing print quality. The positioning rod can be set as a non-rotatable cylinder or cuboid, and the lower surface of the cylinder or the cuboid can be set as a smooth curved surface, thereby reducing the friction between the two when the guide belt runs after the positioning rod is lowered.
