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] In flat printing of lightweight materials (such as paper, cartons, and plastics), since 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 printing position calculation error needs to be controlled below a millimeter, otherwise the effect of the entire material will be greatly reduced, and the effect will be too poor and even the entire lightweight material will 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 an accurate 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, control the positioning rod to be lifted and the rear pressure roller to be lowered;

[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 lifted based on the advance amount of the rear pressure roller being lifted;

[0016] When the rear end position 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 implementation, the control method of the printing system further includes:

[0018] 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, the nozzle is controlled to print.

[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 feeding device and at least one fan;

[0020] Along the advancing 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 advancing 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 implementation, 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 position of the material to be printed is aligned with the front end position of the positioning rod by front loading, the guide belt is controlled to move a preset reverse moving distance in a direction opposite to the forward direction; the preset reverse moving distance is the sum of the length of the material to be printed and the width of the positioning rod;

Since the actual position of the material to be printed changes with the movement of the guide belt, and 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 is also variable. 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, and the printing accuracy can be improved 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 being offset forward and backward or offset left and right, thereby improving the printing accuracy from the second level, thereby improving the printing efficiency.

[0042] In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and their order is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be 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 interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

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

[0045] In printing scenarios with lightweight materials (such as paper, cartons, and plastics), 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 within the millimeter level or even higher, such as scenarios where multiple materials to be printed need to be coordinated or nested. For such scenarios with extremely high requirements for printing accuracy and lightweight materials to be printed, such as Figure 1 As shown, an embodiment of the present invention provides a control method of a printing system, which may include:

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

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

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

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

[0050] The printing system may further include a loading device, which is used to place the material to be printed on the guide belt. Furthermore, the loading device may also 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 to the position of the positioning rod by the guide belt within the preset loading interval.

[0051] It is understandable that, from a top view, the projection of the front 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 roller 40 on the guide belt is also a rectangle. Therefore, the printing information can also include the front roller size, the positioning rod size and the rear roller size, wherein the front roller size includes the front roller length and the front roller width, the positioning rod size includes the positioning rod length and the positioning rod width, and the rear roller size includes the rear roller length and the rear 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, for the material to be printed, its actual position also includes the front position and the rear position of the material to be printed. Correspondingly, the printing information also includes the size of the material to be printed, and the size of the material to be printed may include the length of the material to be printed and the width of the material to be printed. The rear position of the material to be printed can be determined based on the front position of the material to be printed and the size of the material to be printed.

[0054] The print trigger instruction may be an instruction generated by a 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 a preset feeding interval time ends.

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

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

[0058] The production mode characterization requires printing of multiple materials to be printed. In a specific printing scenario, as soon as printing starts, the guide belt carries the materials to be printed and moves along the forward direction of the guide belt at a preset moving speed. Therefore, the moving speed of the guide belt is the moving speed of the materials to be printed.

[0059] The positioning rod is behind the nozzle. When the positioning rod falls, one of the functions of the positioning rod is to block the material to be printed. In this scenario, the front end of the material to be printed is aligned with the rear end of the positioning rod. Because of this, the second function of the positioning rod is to initially position the material to be printed. As mentioned above, the initial position is determined based on the position of the positioning rod. When the initial position and moving speed of the material to be printed are known, the actual position of the material to be printed relative to the initial position during movement 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. Firstly, each material to be printed can be positioned, thereby improving the printing accuracy from the first level, thereby improving the printing efficiency. Secondly, 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 or backward or shifting left or right, thereby improving the printing accuracy from the second level, thereby improving the printing efficiency.

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

[0063] In step 130, based on the positional relationship between the actual position and the positions of the multiple controlled objects, controlling the rise and fall of the controlled object 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 falling amount of the front pressure roller;

[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 being lifted;

[0067] (4) 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 the front pressing roller lifting.

[0068] In step (1), it is also mentioned above that for the first material to be printed in the batch of materials to be printed, the user may press the "print start" button to trigger the print trigger instruction; for other materials to be printed in the batch of materials to be printed, the print trigger instruction may be triggered when the preset material loading interval expires. The generation of the print trigger instruction may indicate that the material to be printed has been aligned with the positioning rod in advance. Optionally, the material to be printed has been aligned with the positioning rod, which 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 obtains the print trigger instruction, the control positioning rod is lifted and the rear pressure roller is lowered. The purpose of lifting the positioning rod is to no longer block the advance of the material to be printed. After the positioning rod is lifted, the material to be printed can move with the guide belt at a uniform moving speed. The purpose of lowering the rear pressure roller is to fix the material to be printed to a certain extent, so that the material to be printed does not produce relative movement relative to the guide belt during movement, thereby making the material to be printed more firmly attached to the guide belt, so that the print image can be printed on the material to be printed more accurately.

[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 which 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 may be greater than zero, in which case the preset printing distance represents a pattern distance at which the front end position of the material to be printed exceeds the front end position of the nozzle, where the pattern distance refers to a 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 may 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 fall.

[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] Like the role of the rear pressure roller falling, the role of the front pressure roller falling is also to fix the material to be printed to a certain extent, so that the material to be printed does not move relative to the guide belt during movement, thereby making the material to be printed more firmly attached to the guide belt, so that the print image can be printed more accurately on the material to be printed. Of course, if the front pressure roller and the rear pressure roller are combined and both are in the falling state, the stability of the material to be printed is the strongest.

[0077] In step (3), the rear roller lifting advance amount is a distance indicating that the material to be printed is about to leave the rear roller area. The rear roller lifting advance amount indicates the distance between the rear end position of the printed material and the rear end position of the rear roller. Specifically, the rear roller lifting advance amount 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 position of the material to be printed is close to the rear pressure roller and the distance between the rear end position of the material to be printed and the rear end position of the rear pressure roller is greater than or equal to the second distance, controlling the rear pressure roller to lift. The second distance is greater than 0.

[0079] Similarly, the front roller lifting advance amount is also a distance, indicating that the material to be printed is about to leave the front roller area. The front roller lifting advance amount is the distance between the rear end position of the printed material and the rear end position of the front roller. Further, the front roller lifting advance amount is the distance between the rear end position of the material to be printed and the rear end position of the front roller when the rear end position of the material to be printed is close to the rear end position of the front roller.

[0080] Therefore, step (4) may specifically include: when the rear end position of the material to be printed is close to the front pressure roller and the distance between the rear end position of the material to be printed and the rear end position 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 where the positioning rod is located, the positioning rod is controlled to fall, and the loading device is controlled to start 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 position of the positioning rod and be intercepted by the positioning rod. When the preset loading interval ends, the printing trigger instruction is triggered, the positioning rod is lifted, and the rear pressure roller falls. Therefore, the preset loading interval can also represent the time from the falling to the lifting of the positioning rod after a material to be printed is printed in the continuous printing process.

[0082] When the preset material loading interval is over, the printing system can obtain the printing trigger instruction, control the actions of multiple control objects according to the control method in the printing process of the previous material to be printed, and start printing the new material to be printed until all the materials to be printed are printed.

[0083] Because the material of the material to be printed is a light and soft material with a certain thickness, when it moves on the guide belt, the friction coefficient is low, causing the position of the material to be printed to shift. This situation can be effectively avoided when the front and rear pressure rollers are used for fixing. However, when the material to be printed is about to leave the pressure roller, the edge of the material is easily flattened by the pressure roller, and the front pressure roller or the rear pressure roller will produce a slight thrust on the material to be printed, causing the position of the material to be printed to shift, thereby causing the printing position deviation. Therefore, in the embodiment of the present invention, the advance amount of lifting the front pressure roller and the advance amount of lifting the rear pressure roller are set, which can prevent the front pressure roller or the rear pressure roller from crushing the end of the material to be printed or causing the material to be printed to shift and move, ultimately improving the printing accuracy and printing 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 position of the material to be printed is aligned with the front end position of the positioning rod by the front loading method, the guide belt is controlled to move a preset reverse moving distance in the direction opposite to the forward direction; the preset reverse moving 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 a 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 moving 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 debugging 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 lifting and lowering 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 each time. According to the printing pattern obtained after the printing is completed, 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] The reason why the debugging mode uses the front loading method is that in some actual printing scenarios, the printing equipment in the printing system is huge, and the staff walks from the front of the printing equipment to the back of the printing equipment, the distance is about ten meters, because the computer and control buttons are in front of the printing equipment, and the debugging mode must have an operator present. In order to avoid trouble for the operator, the adjustment mode often uses the front loading method to improve printing convenience. Rear loading is suitable for the production mode of printing large quantities of materials, and the materials to be printed can be continuously transported to the printing area from the automatic loading device at the rear.

[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] Based on the print instruction, the nozzle is controlled to print; 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) when it falls.

[0107] The fall of the rear pressure roller represents the start of printing. The so-called manual means that the rear pressure roller is manually dropped, and after pressing the material to be printed, the positioning rod will automatically lift up, and the automatic means that the material can be loaded within the "preset loading interval". When the time is up, the rear pressure roller will automatically fall, lift the positioning rod, and then start printing. Manual control of the rear pressure roller is used for printing tests in the debugging mode, or manual feeding scenarios without automatic feeding machines. Automatic control of the rear pressure roller is used to automatically feed the material using the loading device, realizing full automation of the entire printing process.

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

[0109] When loading the materials to be printed, the front end position of the first material to be printed must be manually aligned with the positioning rod before printing can begin. The second material to be printed, the third material to be printed, and so on in the production mode do not need to be manually aligned. You only need to 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, the rear pressure roller and the positioning rod can all be manually controlled to improve printing convenience.

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

[0112] Based on the fan start command, 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] Based on the fan operating parameters, the fan speed is controlled.

[0116] It should be noted that the adsorption force is input by the user for the first time, and the adsorption force and material parameters are stored accordingly. 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, so it is necessary to adjust the adsorption force of the material to be printed by adjusting the adsorption force. In the scenario where the printing accuracy is extremely high and the material to be printed is 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 through FLash to prevent the adjusted parameters from being lost due to power failure 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] Since the amount of data processed by the PC in the printing system is usually large, the control method for peripheral devices can be stored in the ARM motherboard. Compared with the Windows system, the Linux system runs more stably and faster in the embedded field, and occupies fewer resources, so the ARM motherboard usually uses the Linux system. The control method of the printing system is stored in the ARM motherboard, and the ARM motherboard executes the above control method. On the one hand, it avoids the frequent transmission and reception of large amounts of data between the PC and the motherboard, reducing the pressure of data transmission. On the other hand, it shortens the transmission path of the control method data and improves 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 function actions are directly controlled by the arm motherboard, which is not suitable for the windows system environment.

[0120] The control method of the printing system based on the 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 the function implementation freedom is high; 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 the trimmed Linux kernel can be less than 150KB, and it can be customized according to the resource constraints in the embedded field; 4) Compared with other operating systems, Linux runs more stably and faster in the embedded field and occupies fewer resources.

[0121] In a specific implementation, 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 moving distance is a first moving distance, the nozzle is controlled to print; the first moving distance indicates that when the front end position of the material to be printed leaves the front end position of the nozzle, the distance between the front end position of the material to be printed and the front end position of the nozzle is a first preset distance; the first preset distance is greater than or equal to zero; the real-time moving distance is determined based on the initial position; the initial position can be set to 0, and the actual moving distance of the material to be printed can be determined according to the moving 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 lifted; 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 the 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 material to be printed coincides with the rear end position of the front pressure roller;

[0125] When the real-time moving distance is the fourth moving distance, the positioning rod is controlled to fall; the fourth moving distance indicates that the rear end position of the material to be printed 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] Combination Figure 3 , the control method of the control system is briefly described.

[0128] like Figure 3 As shown, for the first material, manually drop 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 will step forward 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 pressure roller area under the stepping of the guide belt, the rear pressure 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 down to 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 moving direction 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 improve the 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 moving 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 roller is the same as the cylindrical radius of the rear roller, the rotation speed of the front roller can also be the same as the moving speed of the guide belt, the groove on the surface of the guide belt and the groove on the side surface of the front roller have the same width, and the height of the lowest point of the side surface of the cylinder of the front roller when the front roller falls can be slightly higher than the height of the lowest point of the side surface of the cylinder when the rear roller falls, so as to avoid unnecessary deformation of the material to be printed due to mechanical errors in the sizes of the front roller and the rear roller, or wrinkles on the surface of the material to be printed during movement, thereby reducing the printing quality. When the cylindrical radius of the front roller is different from the cylindrical radius of the rear roller, the front roller can be set to a smooth side surface, and the height of the lowest point of the side surface of the cylinder of the front roller when the front roller falls can be slightly higher than the height of the lowest point of the side surface of the cylinder when the rear roller falls, so as to avoid unnecessary deformation of the material to be printed due to the different cylindrical radius of the front roller and the rear roller, or wrinkles on the surface of the material to be printed during movement, thereby reducing the printing quality. The positioning rod can be set as a non-rotatable cylinder or a cuboid, and the lower surface of the cylinder or the cuboid can be set as a smooth curved surface, so as to reduce the friction between the two when the guide belt runs after the positioning rod is lowered.
