Description

Technical Field

[0001] This application relates to the field of engraving machine technology, and more particularly to engraving machines. Background Technology

[0002] A home engraving machine is a small material processing device designed for individual and family users. It is primarily used for creative handicrafts such as cutting patterns, engraving lettering, and cutting designs from paper, self-adhesive labels, cardstock, leather, and various films. With the rise of DIY crafts, journaling, and personalized gift customization, home engraving machines are gaining popularity due to their ease of operation and wide applicability to various materials.

[0003] Home-use engraving machines in related technologies typically only have a single cutting function and lack an integrated printing module. In actual use, users need to first use a separate printer (such as a home inkjet or laser printer) to print the desired pattern or text onto the material. Then, the printed material is removed from the printer and manually placed onto the cutting platform of the engraving machine. The position and angle of the material are adjusted manually by visual alignment so that the cutting head can cut along the outline of the printed pattern. This entire process requires repeated switching between two separate devices and involves manual material transfer and alignment. This leads to two problems: First, during manual alignment, the material inevitably shifts in position or angle during transfer and placement. Furthermore, the engraving machine lacks the ability to automatically identify and calibrate the position of the printed pattern, making it easy for misalignment between the cutting outline and the printed pattern to occur. This results in misaligned cutting, uneven border cutting, or even cutting into the pattern itself, leading to defective products and making it difficult to guarantee cutting accuracy and yield. Second, as two separate devices, the printer and engraving machine require separate desktop space, which is too large for a home environment, hindering storage and daily use. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems existing in the related art. To this end, this application proposes an engraving machine.

[0005] The engraving machine according to the first aspect of this application includes a main body, a cutting module, a printing module, a moving module, and a first driving module;

[0006] The main body has an installation cavity;

[0007] Both the cutting module and the printing module are located within the mounting cavity, and both are connected to the moving module. The cutting module is used to cut materials, and the printing module is used to print graphics on the materials.

[0008] Both the first drive module and the moving module are located inside the mounting cavity. The first drive module is connected to the moving module, and the first drive module is used to drive the moving module to move.

[0009] According to one embodiment of this application, the first drive module includes a first drive motor, a first transmission member, and a guide shaft. The first drive motor is disposed in the mounting cavity, and the first transmission member and the guide shaft are mounted on the main body. The first transmission member connects the moving module and the first drive motor so that the first drive motor can drive the moving module to move through the first transmission member. The moving module is slidably connected to the guide shaft.

[0010] According to one embodiment of this application, the engraving machine further includes a second drive module, which is mounted on the main body and is used to drive the material to move relative to the cutting module and / or the printing module.

[0011] According to one embodiment of this application, the second drive module includes a second drive motor, a second transmission component, a first roller shaft, and a second roller shaft. The second drive motor is connected to the second transmission component, and the first roller shaft and the second roller shaft are arranged opposite to each other.

[0012] A gap for accommodating material is formed between the first roller shaft and the second roller shaft. The first roller shaft is connected to the second transmission component. The second drive motor drives the first roller shaft to rotate through the second transmission component, so that the first roller shaft and the second roller shaft can move the material.

[0013] According to one embodiment of this application, the main body includes a housing and a frame, the housing forming the mounting cavity, and the frame disposed within the mounting cavity;

[0014] The frame is formed with guide rails, and the moving module has a guiding structure that slides with the guide rails.

[0015] According to one embodiment of this application, the printing module includes an ink cartridge holder, an ink cartridge, and a cover plate. The ink cartridge holder has a receiving cavity for accommodating the ink cartridge, and the ink cartridge holder also has an opening communicating with the receiving cavity. The ink cartridge holder has an elastic snap-fit.

[0016] The first end of the cover plate is rotatably connected to the ink cartridge holder, and the second end of the cover plate has a snap-fit ​​portion. The cover plate can switch between an open state and a closed state. In the closed state, the elastic buckle snaps into the snap-fit ​​portion, and the cover plate covers the opening. In the open state, the elastic buckle disengages from the snap-fit ​​portion.

[0017] According to one embodiment of this application, the printing module further includes an elastic element connected to the cover plate;

[0018] During the process of the cover plate switching from the open state to the closed state, the cover plate compresses the elastic element;

[0019] During the process of the cover plate switching from the closed state to the open state, the elastic element applies an elastic force to the cover plate, causing the second end of the cover plate to rotate away from the ink cartridge holder.

[0020] According to one embodiment of this application, the main body includes a housing having a mounting cavity, the housing having an inlet and outlet communicating with the mounting cavity;

[0021] The engraving machine also includes a sliding cover, which is rotatably connected to the housing to switch between a first position and a second position. In the first position, the sliding cover is disposed on the inlet and outlet, and in the second position, the sliding cover is located in the mounting cavity, with the interior of the housing exposed to the inlet and outlet.

[0022] According to one embodiment of this application, the engraving machine further includes two connecting plates, which are respectively located on both sides of the sliding cover. The first end of the connecting plate is rotatably connected to the housing, and the second end of the connecting plate is connected to the sliding cover.

[0023] According to one embodiment of this application, the housing forms a limiting groove, the cover plate is engaged with the limiting groove, and the cover plate is movable along the limiting groove.

[0024] The beneficial effects of the embodiments of this application are as follows:

[0025] In the embodiments of this application, firstly, by integrating the cutting module and the printing module into the main body of the same engraving machine and sharing the same moving module and first drive module, integrated automatic operation of graphic printing and contour cutting is achieved. Users no longer need to manually transfer and position materials between separate printers and engraving machines, avoiding defects such as misalignment, skewness, or cutting into the pattern itself caused by manual alignment deviations, significantly improving cutting accuracy and yield. Secondly, the printing module and cutting module share the same moving module, reducing redundant drive and guide structures, simplifying the overall equipment structure, lowering manufacturing costs, and making the equipment more compact, reducing desktop space occupation in a home environment, and improving the convenience of equipment storage and daily use. Furthermore, after printing, the cutting module can directly track and cut according to the actual position of the printed graphic in the same coordinate system. Even if there is a slight positional deviation in the material placement, the cutting path can automatically follow the actual position of the printed pattern, further improving processing accuracy and error tolerance.

[0026] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The following is combined Figures 1 to 8 This application describes the engraving machine, control method, and storage medium.

[0040] According to the embodiments of the first aspect of this application, see [link / reference]. Figure 1 , Figure 3 and Figure 4 A lettering engraving machine is provided. The lettering engraving machine includes a main body 1, a cutting module 2, a printing module 3, a moving module 4, and a first drive module 5;

[0041] The main body 1 has an mounting cavity 11;

[0042] Both the cutting module 2 and the printing module 3 are located inside the mounting cavity 11. Both the cutting module 2 and the printing module 3 are connected to the moving module 4. The cutting module 2 is used to cut the material, and the printing module 3 is used to print graphics on the material.

[0043] Both the first drive module 5 and the moving module 4 are located in the mounting cavity 11. The first drive module 5 is connected to the moving module 4, and the first drive module 5 is used to drive the moving module 4 to move.

[0044] Understandably, when a user needs to perform engraving or cutting operations, the material to be processed is first placed on the working platform of the main body 1. The printing module 3, driven by the moving module 4, moves to a predetermined starting position above the material and prints the required pattern or text outline on the material surface according to the user-set graphic data. After printing, the moving module 4 drives the cutting module 2 to move to the starting position of the printed graphic, and the cutting module 2 cuts according to the printed graphic outline trajectory. Since the printing module 3 and the cutting module 2 are both connected to the same moving module 4 and share the same set of moving module 4 and first drive module 5, the position coordinates of the printing module 3 when printing graphics on the material and the position coordinates of the cutting module 2 when performing cutting are based on the same coordinate system and the same motion reference. The relative positional relationship between printing and cutting is directly determined by the motion accuracy of the moving module 4, and there is no deviation introduced by manual transfer or manual alignment.

[0045] The beneficial effects of this embodiment are significant. First, by integrating the cutting module 2 and the printing module 3 into the main body 1 of the same engraving machine and sharing the same moving module 4 and first drive module 5, integrated automatic operation of graphic printing and outline cutting is achieved. Users no longer need to manually transfer and position materials between separate printers and engraving machines, avoiding defects such as misalignment, skewness, or cutting into the pattern due to manual alignment deviations, thus greatly improving cutting accuracy and yield. Second, the printing module 3 and the cutting module 2 share the same moving module 4, reducing redundant drive and guide structures, simplifying the overall structure of the equipment, lowering manufacturing costs, and making the equipment more compact, reducing desktop space occupation in a home environment, and improving the convenience of equipment storage and daily use. In addition, after printing, the cutting module 2 can directly track and cut according to the actual position of the printed graphic in the same coordinate system. Even if there is a slight positional deviation when the material is placed, the cutting path can automatically follow the actual position of the printed pattern, further improving processing accuracy and fault tolerance.

[0046] In some examples, printing module 3 can be an inkjet printhead or a thermal transfer printhead for forming patterns on the material surface. Cutting module 2 can be a blade holder or a laser cutting head. Moving module 4 can be a carriage or slide that moves along the X and Y axes, and the first drive module 5 can be a stepper motor with synchronous belt drive or lead screw drive to achieve precise positioning and movement of cutting module 2 and printing module 3 in a two-dimensional plane.

[0047] In some embodiments, see Figure 4The first drive module 5 includes a first drive motor 51, a first transmission component 52, and a guide shaft 53. The first drive motor 51 is located in the mounting cavity 11. The first transmission component 52 and the guide shaft 53 are mounted on the main body 1. The first transmission component 52 connects the moving module 4 and the first drive motor 51 so that the first drive motor 51 can drive the moving module 4 to move through the first transmission component 52. The moving module 4 is slidably connected to the guide shaft 53.

[0048] Understandably, when the first drive motor 51 receives a control command, its output shaft begins to rotate, driving the first transmission component 52 to move (e.g., rotating a synchronous belt or a lead screw). Since the moving module 4 is fixedly connected to the output end of the first transmission component 52, the moving module 4 moves along the axial direction of the guide shaft 53 under the drive of the first transmission component 52. The guide shaft 53 provides precise linear guidance for the movement of the moving module 4, ensuring that the moving module 4 does not wobble or sway during movement, thereby guaranteeing the positional accuracy and smooth movement of the printing module 3 and cutting module 2 connected to the moving module 4 during the movement process.

[0049] The beneficial effects of this embodiment are significant. First, the movement of the moving module 4 along the guide shaft 53 is driven by the cooperation of the first drive motor 51 and the first transmission component 52, achieving precise and smooth movement of the printing module 3 and the cutting module 2 within the mounting cavity 11 along a certain axial direction (e.g., the X-axis). The presence of the guide shaft 53 ensures the linearity of the movement of the moving module 4 and the repeatability of its positioning, keeping the positional deviation of printing and cutting within a very small range. Second, the printing module 3 and the cutting module 2 share the same set of drive motors, transmission components, and guide shaft 53, reducing redundant drive and guide structures, simplifying the equipment structure, lowering manufacturing costs, and facilitating the miniaturization and compact design of the equipment. Furthermore, the sliding fit between the guide shaft 53 and the moving module 4 can employ linear bearings or self-lubricating materials to reduce frictional resistance and improve transmission efficiency and service life.

[0050] In some examples, the first transmission component 52 may be a synchronous belt drive mechanism, including a driving synchronous pulley, a driven synchronous pulley, and a synchronous belt, with the moving module 4 fixed to the synchronous belt. The guide shaft 53 may be two parallel linear optical shafts, with the moving module 4 slidingly engaged with the optical shafts via linear bearings. The first drive motor 51 may be a stepper motor to achieve precise position control. The moving module 4 may also be equipped with a second drive motor and a second transmission component 61 in another direction perpendicular to the guide shaft 53 (e.g., the Y-axis direction) to achieve movement in a two-dimensional plane.

[0051] In some embodiments, see Figure 4The engraving machine also includes a second drive module 6, which is installed on the main body 1. The second drive module 6 is used to drive the material to move relative to the cutting module 2 and / or the printing module 3.

[0052] Understandably, during the processing, when the printing module 3 needs to print graphics on the material surface or the cutting module 2 needs to cut the material along a preset trajectory, the control unit controls the first drive module 5 and the second drive module 6 to move according to the preset motion path data. The first drive module 5 drives the cutting module 2 and the printing module 3 to move along the X-axis, and the second drive module 6 drives the material to move along the Y-axis. The coordinated movement of the two enables the printing nozzle or cutting head to complete positioning and trajectory movement at any plane position on the material. Since the material is actively moved by the second drive module 6 rather than relying on manual pushing, the material's feeding speed and feed amount can be precisely controlled, ensuring the accuracy and consistency of the material's position during printing and cutting.

[0053] The beneficial effects of this embodiment are significant. First, through the coordinated operation of the second drive module 6 and the first drive module 5, precise positioning and motion control of the printing module 3 and the cutting module 2 within the two-dimensional plane on the material are achieved, making the printing and cutting processes fully automated. This eliminates the need for manual material movement or adjustment, further improving processing accuracy and ease of operation. Second, the introduction of the second drive module 6 enables the equipment to handle larger materials (through segmented feeding) or achieve automatic continuous material feeding, improving the equipment's processing capacity and operational efficiency. Third, the material is actively driven by the second drive module 6, eliminating the need for users to excessively pursue precise placement—the system can automatically compensate for initial positional deviations through the coordinated operation of the first drive module 5 and the second drive module 6, further reducing the skill requirements for user operation and improving the ease of use and fault tolerance of the home appliance.

[0054] In some examples, the second drive module 6 can use a stepper motor in conjunction with a feeding roller or a paper pressing roller to move the material along the feeding direction through friction or clamping. The feeding roller can be positioned below the working path of the printing module 3 and the cutting module 2, cooperating with the movement direction of the first drive module 5 (e.g., the X-axis direction) to achieve positioning in the XY two-dimensional plane.

[0055] In some embodiments, see Figure 4 The second drive module 6 includes a second drive motor, a second transmission component 61, a first roller shaft 62 and a second roller shaft 63. The second drive motor is connected to the second transmission component 61, and the first roller shaft 62 and the second roller shaft 63 are arranged opposite to each other.

[0056] A gap for accommodating material is formed between the first roller shaft 62 and the second roller shaft 63. The first roller shaft 62 is connected to the second transmission member 61. The second drive motor drives the first roller shaft 62 to rotate through the second transmission member 61, so that the first roller shaft 62 and the second roller shaft 63 can move the material.

[0057] Understandably, when material is fed into the gap between the first roller shaft 62 and the second roller shaft 63, the second drive motor starts, and its output shaft transmits power to the first roller shaft 62 through the second transmission component 61 (e.g., synchronous belt, gear set, or worm gear), driving the first roller shaft 62 to rotate around its axis. Since the second roller shaft 63 is positioned opposite to the first roller shaft 62 and in contact with the material, the rotation of the first roller shaft 62 causes the material to move along the feed direction through friction, and the second roller shaft 63, as a driven component, rotates accordingly to match the movement of the material. By controlling the rotation direction, speed, and angle of the second drive motor, precise control of the material feed direction, feed speed, and feed amount can be achieved. The second drive module 6 works in conjunction with the first drive module 5, causing the material to move along the first direction under the drive of the second drive module 6, while the cutting module 2 and the printing module 3 move along a second direction perpendicular to the first direction under the drive of the first drive module 5, thereby achieving fully automatic two-dimensional precise positioning of the printing and cutting positions.

[0058] The beneficial effects of this embodiment are significant. First, the first roller shaft 62 is rotated by the second drive motor, and the friction between the roller and the material drives the automatic feeding of the material, realizing the automation and precision of material conveying and avoiding the uneven speed or positional deviation that may be caused by manual material pushing. Second, the gap formed by the relative arrangement of the first roller shaft 62 and the second roller shaft 63 can accommodate materials of different thicknesses, and can adapt to materials of different materials by adjusting the distance between the two roller shafts or by utilizing the elastic deformation of the rollers themselves, thus having good versatility. Third, the roller friction feeding method causes little damage to the material surface and has wide adaptability, especially suitable for feeding and conveying flexible materials such as paper, self-adhesive labels, and films. In conjunction with the movement control of the aforementioned first drive module 5, it together constitutes the two-dimensional automatic positioning and feeding system of the engraving machine, so that the printing and cutting processes can be completed without manual intervention, significantly improving the automation level and ease of use of the equipment.

[0059] In some examples, the second transmission element 61 may be a synchronous belt drive or a gear drive. The surfaces of the first roller shaft 62 and the second roller shaft 63 may be covered with a friction material layer (e.g., rubber or silicone) to increase the friction between the material and prevent slippage during transport.

[0060] In some embodiments, see Figure 3 and Figure 4The main body 1 includes a housing 12 and a frame 13. The housing 12 forms a mounting cavity 11, and the frame 13 is disposed in the mounting cavity 11.

[0061] The frame 13 is formed with a guide rail, and the moving module 4 has a guide structure that slides with the guide rail.

[0062] Understandably, when the first drive motor 51 drives the moving module 4 to move via the first transmission component 52, the guide structure on the moving module 4 slides along the guide rail on the frame 13, and the guide rail provides precise linear constraint on the movement direction of the moving module 4. Since the guide rail is fixed to the frame 13, and the frame 13 is fixedly connected to the housing 12 as a rigid base, the movement trajectory of the moving module 4 maintains a constant geometric relationship with the frame 13 and the housing 12, thereby ensuring the positional accuracy and motion repeatability of the printing module 3 and the cutting module 2 connected to the moving module 4 during the movement process.

[0063] The beneficial effects of this embodiment are significant. First, by forming a guide rail on the frame 13 and slidingly engaging with the guide structure of the moving module 4, high-precision and high-rigidity linear motion guidance is provided for the moving module 4, effectively ensuring the smooth movement and positional repeatability of the printing module 3 and the cutting module 2 during movement, thus reliably guaranteeing the positioning accuracy of printing and cutting. Second, as an internal load-bearing structure independent of the housing 12, the frame 13 has better rigidity and stability than directly setting the guide rail on the housing 12, and can better resist the vibration and impact forces generated during printing and cutting, which is beneficial to improving the processing accuracy and service life of the equipment. Third, the combination of the guide rail and the guide structure is simple in structure, low in cost, and easy to install and maintain, which is suitable for the dual requirements of reliability and economy for home engraving machines.

[0064] In some examples, the guide rail can be a linear guide rail or a cylindrical optical axis, and the guiding structure can be a linear bearing or a plastic slider that mates with the guide rail. The frame 13 can be precision machined from aluminum alloy or steel plate to ensure the straightness and flatness of the guide rail.

[0065] In some embodiments, see Figure 5 and Figure 6 The printing module 3 includes an ink cartridge holder 31, an ink cartridge 32 and a cover plate 33. The ink cartridge holder 31 has a receiving cavity 311 for receiving the ink cartridge 32. The ink cartridge holder 31 also has an opening communicating with the receiving cavity 311. The ink cartridge holder 31 has an elastic buckle 312.

[0066] The first end of the cover plate 33 is rotatably connected to the ink cartridge holder 31, and the second end of the cover plate 33 has a snap-fit ​​part 331. The cover plate 33 can switch between an open state and a closed state. In the closed state, the elastic buckle 312 snaps into the snap-fit ​​part 331, and the cover plate 33 covers the opening. In the open state, the elastic buckle 312 disengages from the snap-fit ​​part 331.

[0067] Understandably, when it is necessary to install or replace the ink cartridge 32, the user applies force to the second end of the cover plate 33, causing the elastic buckle 312 to elastically deform and disengage from the locking part 331. After the cover plate 33 is unlocked, it rotates around its first end to the open state, exposing the opening. The user can then remove the ink cartridge 32 from the receiving cavity 311 or place a new ink cartridge 32 into the receiving cavity 311. After the ink cartridge 32 is installed in place, the user rotates the cover plate 33 in the opposite direction around its first end until it is closed in the open position. When the locking part 331 of the cover plate 33 contacts the elastic buckle 312 of the ink cartridge holder 31, the elastic buckle 312 elastically deforms. After the locking part 331 passes the locking position of the buckle, the elastic buckle 312 returns to its original shape and forms a locking engagement with the locking part 331, fixing the cover plate 33 in the closed state.

[0068] The beneficial effects of this embodiment are significant. First, the snap-fit ​​between the elastic buckle 312 and the snap-fit ​​part 331 enables quick locking and unlocking of the cover 33 and the ink cartridge holder 31, allowing users to replace the ink cartridge 32 without any tools, greatly improving the convenience and efficiency of ink cartridge 32 replacement. Second, the elastic buckle 312 and the snap-fit ​​part 331 form a reliable mechanical interlock when closed, effectively preventing the cover 33 from accidentally opening due to vibration or movement during equipment operation, ensuring the positional stability and ink supply reliability of the ink cartridge 32 during printing. Third, the cover 33, with one end rotating and the other end snap-fitted, remains connected to the ink cartridge holder 31 when open, avoiding the risk of loss after disassembly, simplifying the operation steps, and improving the user experience.

[0069] In some examples, the resilient latch 312 may be a cantilever latch integrally extending from the side wall of the cartridge holder 31, with a hook at its end. The latching portion 331 may be a latching hole or a protruding latching block on the cover plate 33.

[0070] In some examples, the resilient snap-fit ​​312 has an arcuate guide surface, which is used to guide the snap-fit ​​portion to snap into the resilient snap-fit ​​312.

[0071] In some embodiments, see Figure 5 and Figure 6 The printing module 3 also includes an elastic element 34, which is connected to the cover plate 33;

[0072] During the process of switching from the open state to the closed state, the cover plate 33 compresses the elastic element 34;

[0073] During the process of switching the cover plate 33 from the closed state to the open state, the elastic member 34 applies an elastic force to the cover plate 33, so that the second end of the cover plate 33 rotates away from the ink cartridge holder 31.

[0074] Understandably, when the user rotates the cover 33 from the open to the closed state, the cover 33 rotates downwards around its first end pivot, simultaneously contacting and compressing or twisting the elastic element 34, causing the elastic element 34 to undergo elastic deformation and store energy. When the cover 33 is fully closed and the elastic latch 312 engages with the latching part 331, the elastic element 34 is in a deformed state but is locked by the latch and cannot be released. When the user needs to replace the ink cartridge 32 and presses the elastic latch 312 to unlock it, the latch disengages from the latching part 331, the cover 33 loses its locking constraint, and the elastic element 34 immediately releases its stored elastic potential energy, applying an elastic force to the cover 33 in the opening direction, causing the cover 33 to automatically spring up and remain in the open state, allowing the user to directly remove or place the ink cartridge 32 without manually lifting the cover 33.

[0075] The beneficial effects of this embodiment are significant. First, through the energy storage and release function of the elastic element 34, the cover 33 can automatically spring up to the open state after the latch is unlocked. The user does not need to manually lift the cover 33, realizing one-handed operation for ink cartridge 32 replacement, greatly improving the convenience and efficiency of ink cartridge 32 replacement. Second, the elastic element 34 is continuously deformed in the closed state, applying a continuous opening tendency force to the cover 33. However, in the latch-locked state, this force is balanced by the latch and will not affect the closing and sealing effect of the cover 33. It automatically takes effect after the latch is unlocked, with timely and reliable action response. Third, this elastic assist structure reduces the need for users to manually lift the cover during the opening process, reducing the risk of damage to the ink cartridge 32 or ink cartridge holder 31 due to improper operation. It is especially suitable for devices such as home engraving machines aimed at non-professional users, improving the ease of use of the product and the user experience.

[0076] In some examples, the elastic element 34 may be a torsion spring sleeved on the pivot of the cover plate 33, with one end of the torsion spring abutting against the ink cartridge holder 31 and the other end abutting against the inner side of the cover plate 33. When the cover plate 33 is closed, the torsion spring is twisted, and when the latch is unlocked, the torsion spring drives the cover plate 33 to automatically spring open. The elastic element 34 may also be a compression spring disposed between the ink cartridge holder 31 and the cover plate 33. When the cover plate 33 is closed, the spring is compressed, and when unlocked, the spring extends to push the cover plate 33 open.

[0077] In some embodiments, see Figure 1 and Figure 2The main body 1 includes a housing 12 having a mounting cavity 11, and the housing 12 having an inlet and outlet 121 communicating with the mounting cavity 11;

[0078] The engraving machine also includes a sliding cover 7, which is rotatably connected to the housing 12 to switch between a first position and a second position. In the first position, the sliding cover 7 covers the inlet / outlet 121, and in the second position, the sliding cover 7 is located in the mounting cavity 11, with the interior of the housing 12 exposed to the inlet / outlet 121.

[0079] Understandably, during normal use of the engraving machine, the sliding cover 7 is in the first position, covering the inlet / outlet 121 to prevent external dust and debris from entering the mounting cavity 11, protecting the printing module 3, cutting module 2, and other internal components from contamination, while maintaining the cleanliness and integrity of the equipment's appearance. When the user needs to replace the ink cartridge 32, clean cutting debris, or perform maintenance on internal components, the user pushes or pulls the sliding cover 7, causing it to rotate around its rotating connection point, switching from the first position to the second position. In the second position, the sliding cover 7 is inside the mounting cavity 11, the inlet / outlet 121 is completely open, and the internal space of the housing 12 is exposed to the user's view and operating range. After completing the internal operations, the user rotates the sliding cover 7 in the opposite direction, returning it from the second position to the first position, and re-covering the inlet / outlet 121.

[0080] The beneficial effects of this embodiment are significant. First, by setting an inlet / outlet 121 on the housing 12 and configuring a rotatable sliding cover 7, convenient access to the internal components of the mounting cavity 11 is achieved. Users can replace the ink cartridge 32, clean up waste, or maintain the cutting module 2 without disassembling the housing 12, reducing the difficulty and time cost of daily maintenance. Second, when opened, the sliding cover 7 is retracted into the mounting cavity 11, without occupying additional space outside the device. This avoids the space occupied by the traditional flip-out cover 33, which protrudes outside the device after opening, making it easier to place and use the device in limited desktop space. Third, when in the first position, the sliding cover 7 forms a closed structure with the housing 12, effectively preventing external contaminants such as dust, paper scraps, or liquids from entering the mounting cavity 11, protecting the accuracy and lifespan of the printing and cutting modules 2. In addition, the sliding cover 7 is always connected to the housing 12 and will not be lost due to frequent opening and closing, further improving the practicality and durability of the device.

[0081] In some examples, the sliding cover 7 can be hinged to the lower edge of the inlet / outlet 121, flipped down to open, and slid into the bottom of the mounting cavity 11. The sliding cover 7 can be made of transparent plastic so that the user can observe the state inside the mounting cavity 11 without opening the sliding cover 7.

[0082] In some embodiments, see Figure 2The engraving machine also includes two connecting plates 8, which are located on both sides of the sliding cover 7. The first end of the connecting plate 8 is rotatably connected to the housing 12, and the second end of the connecting plate 8 is connected to the sliding cover 7.

[0083] Understandably, when the user pushes or pulls the sliding cover 7, the connecting plates 8 on both sides of the sliding cover 7 rotate synchronously around their respective first-end rotation axes. Since the two connecting plates 8 are of equal length and arranged parallel to each other, the sliding cover 7 moves along a fixed arc-shaped trajectory under the influence of the connecting plates 8, switching from the first position covering the inlet / outlet 121 to the second position located inside the mounting cavity 11, or reverting to its original position. During the movement, the two connecting plates 8 provide synchronous support and constraint from both sides of the sliding cover 7, ensuring that the sliding cover 7 remains parallel to the side frames of the housing 12 during opening and closing, preventing tilting or jamming.

[0084] The beneficial effects of this embodiment are significant. First, the two connecting plates 8 provide symmetrical rotational support from both sides of the sliding cover 7, ensuring even force distribution and smooth movement during opening and closing. This avoids the tilting, shaking, or jamming that can occur with unilateral drive or support, improving the smoothness of operation and service life of the sliding cover 7. Second, the connecting plates 8, acting as a linkage mechanism, precisely define the movement trajectory of the sliding cover 7, allowing it to smoothly rotate into the mounting cavity 11 after opening and accurately align and tightly fit with the edges of the inlet / outlet 121 of the housing 12 when closed, ensuring sealing and consistent appearance in the closed state. Third, the symmetrical arrangement of the connecting plates 8 on both sides distributes the load of the sliding cover 7 evenly, enhancing its structural stability and resistance to deformation, making it particularly suitable for applications where the sliding cover 7 has a large area or requires frequent opening and closing.

[0085] In some examples, the first end of the connecting plate 8 can be rotatably connected to the inner walls on both sides of the housing 12 via a pivot, and the second end of the connecting plate 8 can be rotatably connected to the side of the sliding cover 7 via a pivot. The connecting plate 8 can be a metal plate or an engineering plastic plate, and its thickness and width are designed according to the weight and size of the sliding cover 7 to ensure sufficient strength and rigidity.

[0086] In some embodiments, the housing 12 forms a limiting groove, the cover plate 33 is engaged with the limiting groove, and the cover plate 33 can move along the limiting groove.

[0087] Understandably, when the user pushes or pulls the sliding cover 7, the engaging portion 331 at the edge of the sliding cover 7 slides along the limiting groove. The limiting groove provides precise linear guidance for the movement of the sliding cover 7, ensuring that the sliding cover 7 can move smoothly in a predetermined direction when switching between the first position and the second position. Since the fit clearance between the engaging portion 331 and the limiting groove is controlled within a preset range, the sliding cover 7 will not wobble laterally or deviate from the predetermined trajectory during movement. When the sliding cover 7 moves to the first position or the second position, the end of the limiting groove can act as a limiting stop to prevent the sliding cover 7 from moving further, thereby achieving precise positioning of the sliding cover 7 in the open and closed states.

[0088] The beneficial effects of this embodiment are significant. First, the locking engagement between the limiting slide groove and the sliding cover 7 provides precise guidance and limitation for the movement of the sliding cover 7, ensuring that the sliding cover 7 always moves along a predetermined straight trajectory during opening and closing, avoiding movement skew or jamming caused by improper manual operation, and improving the smoothness and reliability of the opening and closing of the sliding cover 7. Second, the engagement structure between the limiting slide groove and the locking part 331 interlocks the sliding cover 7 and the housing 12 in the direction perpendicular to the movement direction, effectively preventing the sliding cover 7 from detaching from the housing 12 during movement, and also providing additional holding force in the closed state, enhancing the stability of the sliding cover 7 in the closed position. Third, the limiting slide groove has a simple structure and can be integrally formed with the housing 12, eliminating the need for additional guide parts, reducing manufacturing costs and assembly complexity.

[0089] In some examples, the limiting groove can be a T-shaped groove, and the edge of the sliding cover 7 is provided with a T-shaped protrusion that mates with the T-shaped groove, and the two slide in contact. Buffer pads can be provided at both ends of the limiting groove to absorb the impact energy when the sliding cover 7 reaches the end, reduce noise and protect the parts.

[0090] According to the embodiments of the second aspect of this application, see Figure 7 A method for controlling an engraving machine is provided, comprising:

[0091] S100. Acquire the target image. Specifically, the user can transmit the target image file to be processed to the control unit of the engraving machine via an external device (such as a computer, mobile phone, or USB flash drive) connected to the engraving machine. The target image contains the pattern, text, or outline information that the user needs to engrave or cut. The control unit receives and stores the target image file as the basis for subsequent data processing and manufacturing.

[0092] S200. Based on the target image, determine the printing coordinate data and cutting coordinate data. Specifically, the control unit performs image processing and analysis on the acquired target image, extracting the graphic and textual content (e.g., text, graphics, lines, etc.) and their positional distribution information in the image coordinate system. Based on the extracted graphic and textual content, the control unit generates printing coordinate data and cutting coordinate data respectively. The printing coordinate data includes the position coordinates of each printing point as the printing module 3 moves on the material surface, along with the corresponding inkjet or printing control parameters, used to drive the printing module 3 to reproduce the graphic and textual content of the target image on the material. The cutting coordinate data includes the cutting path coordinates of the cutting module 2 moving along the outline of the target image. These cutting path coordinates are generated based on the same coordinate system as the printing coordinate data, ensuring a precise correspondence between the cutting trajectory and the position of the printed graphic and text. Optionally, the control unit can also perform vectorization processing on the target image, converting the bitmap format image into a vector path to improve the accuracy and smoothness of the cutting path.

[0093] S300. Based on the print coordinate data, control the print module 3 to move and perform the print operation. Specifically, the control unit converts the print coordinate data into motion control commands for the first drive module 5. The first drive module 5 drives the moving module 4 and the print module 3 connected to it to move along a preset print path on the material surface according to the commands. At the same time, it controls the print module 3 (e.g., an inkjet printhead) to spray ink at the corresponding position to form images and text on the material surface according to the content of the target image.

[0094] S400. Based on the cutting coordinate data, control the cutting module 2 to move and perform the cutting operation. Specifically, the control unit converts the cutting coordinate data into motion control commands for the first drive module 5. The first drive module 5 drives the moving module 4 and the cutting module 2 connected to it to move along a preset cutting path on the material surface. At the same time, it controls the cutting module 2 (e.g., a blade holder or laser head) to cut the material. The cutting path precisely corresponds to the outline of the printed graphic, thereby achieving precise cutting of the graphic outline.

[0095] The beneficial effects of this embodiment are significant. First, by generating printing coordinate data and cutting coordinate data separately in the same processing flow after acquiring the target image, the printing path and cutting path are generated based on the same data source and the same coordinate system. The printing module 3 and the cutting module 2 share the same moving module 4 and the same drive system, eliminating the positional deviations introduced by manual transfer and manual alignment, ensuring precise correspondence between the cutting contour and the printed image, effectively avoiding defects such as misaligned patterns, uneven borders, or cutting into the pattern itself, significantly improving cutting accuracy and yield. Second, the printing and cutting operations are automatically executed sequentially on the same device, eliminating the need for users to manually transfer materials between separate printers and engraving machines, simplifying the operation process, saving time, improving processing efficiency, and reducing the space occupied by the equipment in a home environment. Third, this control method allows users to complete the fully automated processing from printing to cutting simply by providing the target image, without requiring professional image processing and path planning knowledge, thus lowering the barrier to entry for using the equipment.

[0096] In some examples, the target image can be in bitmap format (such as JPEG, PNG) or vector format (such as SVG, DXF). The control unit can identify the subject contour edges in the target image using a contour extraction algorithm to generate cutting coordinate data; and generate printing coordinate data using color separation or region filling algorithms. The execution order of printing and cutting operations can be adjusted as needed, for example, printing first and then cutting, or cutting first and then printing, to adapt to different material properties and processing requirements.

[0097] In some embodiments, the step of acquiring the target image includes:

[0098] Receive the user-triggered command to start the creation process and display the mode selection interface;

[0099] Receive the mode selection command triggered by the user in the mode selection interface, and generate the target image according to the mode selection command.

[0100] Understandably, the engraving machine or its connected external device (such as a tablet, mobile phone, or computer) has a start-up button or icon, allowing users to trigger the start-up command via touch or click. Upon receiving this command, the control unit displays a mode selection interface on the device's screen. This interface includes various creation mode options, such as "import from image library," "free drawing," "template selection," or "photo recognition." Users select a creation mode from the selection interface and trigger the corresponding mode selection command. The control unit then generates the target image to be processed based on the selected mode, using a corresponding generation method (e.g., retrieving the target image from the image library, generating the target image based on the user's touch drawing, selecting the target image from a pre-stored template library, or capturing and processing the target image using a camera).

[0101] The beneficial effects of this embodiment are significant. First, by guiding users to sequentially trigger the creation start command and mode selection command, it provides multiple image acquisition methods for users with different needs and skill levels. Users can choose the most suitable creation mode based on their own materials, lowering the barrier to entry for the device and enhancing users' creative freedom and experience. Second, the introduction of the mode selection interface refines the image acquisition process into visual interactive steps. Users do not need experience operating professional graphics processing software to complete the acquisition and preparation of target images, which is especially suitable for home DIY crafts and non-professional users. Third, triggering the mode selection command enables the control components to automatically adapt to the subsequent image processing flow based on the user's selected mode, laying an accurate data foundation for the subsequent generation of printing coordinate data and cutting coordinate data.

[0102] In some examples, the mode selection interface may include a "Select from Album" mode, which allows the user to import an existing image from the device's photo album; a "Take Photo" mode, which allows the user to activate the camera to capture a real object or hand-drawn sketch and automatically process it into a black and white outline; and a "Built-in Template" mode, which allows the user to select a target pattern from the device's pre-stored pattern template library. The creation and mode selection commands can be triggered via the device's touchscreen or physical buttons.

[0103] In some embodiments, the mode selection instruction includes a mode A selection instruction or a mode B selection instruction;

[0104] When the mode A selection instruction is received, the media library is displayed, the user's personalized editing operations on the media in the media library are received, and the target image is generated based on the personalized editing operations;

[0105] When the mode B selection instruction is received, the image uploaded by the user is received, the image is cut out, and the target image is generated based on the cut-out image.

[0106] Understandably, the resource library contains multiple basic patterns, graphic components, text templates, or design elements. After selecting one or more resources from the library, users can personalize the selected resources using the editing tools on the device's display screen. This includes adjusting the size, rotation angle, color, and position of the resources, or combining, overlaying, or deleting multiple resources. The control unit then generates the final target image file based on the user's editing actions.

[0107] When the mode B selection command is received, the system receives the image uploaded by the user, performs a cutout operation on the image, and generates a target image based on the cutout image. Specifically, the user can upload an existing image file (such as a photo, hand-drawn draft, or online image) to the engraving machine via external storage device (such as a USB flash drive), wireless transmission (such as Bluetooth or Wi-Fi), or by taking a photo. The control unit performs image processing on the received image, extracting the main outline and pattern in the image through edge detection, color separation, or AI cutout algorithms, removing the background or other irrelevant areas, and generating a target image with a clear outline. This target image can then be directly used to generate printing coordinate data and cutting coordinate data.

[0108] The benefits of this embodiment are significant. First, by providing two differentiated image acquisition and generation methods, Mode A and Mode B, it meets the creative needs of different users in different scenarios. Mode A provides users without original design capabilities with a basic material library and convenient editing tools, allowing them to create personalized patterns without starting from scratch. Mode B provides users with existing design drafts or physical photos with a quick image import and automatic processing channel, eliminating the tedious steps of manual tracing and redrawing. Second, both modes complete the generation from original materials / images to target images within the device itself, without the need for external computers or professional image processing software, lowering the barrier to entry for the device and enabling home users and DIY enthusiasts to easily complete the entire process from creative idea to physical object processing. Third, the cutout operation effectively separates the subject and background of the image, allowing the cutting module 2 to accurately cut along the subject's outline, avoiding cutting deviations caused by background interference.

[0109] In some examples, the resource library in Mode A can contain common DIY patterns such as animals, plants, geometric shapes, and artistic lettering. The editing tools offer functions such as dragging and scaling, rotation, mirroring, and layer stacking. The cutout operation in Mode B can use an image segmentation algorithm based on deep learning. After uploading the image, users can manually adjust the cutout boundary or click on the main subject area to help optimize the cutout effect.

[0110] In some embodiments, determining print coordinate data and cut coordinate data based on the target image includes:

[0111] Generate print coordinate data based on the target image;

[0112] Extract the image boundary contour of the target image and obtain the cutting coordinate data based on the image boundary contour;

[0113] The printing coordinate data and the cutting coordinate data are both located based on a unified physical origin, and the cutting coordinate data are converted by a preset offset compensation matrix to compensate for the spatial offset between the cutting module 2 and the printing module 3.

[0114] Understandably, the control unit first generates printing coordinate data based on the text and image content of the target image. This printing coordinate data defines the position coordinates of each printing point as the printing module 3 moves across the material surface. Simultaneously, the control unit extracts the image boundary contours of the text and image in the target image using image processing algorithms (such as edge detection and contour tracking). These contours enclose the main body of the pattern or the shape of the text to be cut in the target image. The control unit generates cutting coordinate data based on these image boundary contours. During this process, both the printing coordinate data and the cutting coordinate data are positioned using the same physical origin as a reference (e.g., a fixed reference corner point on the engraving machine's working platform), ensuring that the two sets of coordinate data have a consistent reference system in space. Since the printing module 3 and the cutting module 2 have a spatial offset in their physical installation positions (i.e., their installation positions on the moving module 4 are different), if the same cutting coordinate data is directly used to drive the cutting module 2, the cutting position will have a fixed error in the offset direction of the printed pattern. Therefore, the control unit calls a pre-stored offset compensation matrix, which is obtained through calibration. Its specific parameters reflect the installation offset of the cutting module 2 relative to the printing module 3 in the X and Y axis directions. The control unit performs matrix operations (such as translation compensation or rotation compensation) on the cutting coordinate data and the offset compensation matrix to obtain the actual cutting coordinate data after offset compensation, so that when the cutting module 2 performs the cutting operation along the compensated cutting path, the cutting trajectory and the position of the printed graphic are precisely coincident.

[0115] The beneficial effects of this embodiment are significant. First, by using a dual coordinate correction mechanism of a unified physical origin and an offset compensation matrix, the processing positioning error caused by the difference in physical installation position between the printing module 3 and the cutting module 2 is eliminated, ensuring that the cutting path of the cutting module 2 can be precisely aligned with the outline of the printed image, further improving the processing accuracy and product consistency of the engraving machine in the integrated printing and cutting operation. Second, the offset compensation matrix is ​​a fixed parameter pre-calibrated and stored in the control unit, which is automatically called and applied to the conversion of cutting coordinate data during each processing, eliminating the need for users to manually measure or adjust the offset before each processing, simplifying user operation and lowering the barrier to entry for using the equipment. Third, this coordinate compensation method allows the printing module 3 and the cutting module 2 to be installed without complete overlap, providing greater flexibility and compactness in the structural layout of the equipment, which is beneficial for the miniaturization design of the engraving machine, while ensuring high-precision processing even when there is an installation offset between the modules. This coordinate generation and compensation step, together with the aforementioned printing and cutting operations, constitutes a precise coordinate transfer chain from the target image to the finished product processing.

[0116] In some embodiments, obtaining cutting coordinate data based on image boundary contours includes:

[0117] Identify boundary inflection points on the image boundary contour;

[0118] The path between two adjacent boundary inflection points is defined as a cutting motion path;

[0119] Count the number of cutting motion paths and determine the motion path density level based on the number;

[0120] The cutting speed of cutting module 2 is determined based on the motion path density level.

[0121] Understandably, after extracting the image boundary contour of the target image, the control unit performs curvature analysis or corner detection on the contour curve to identify points where the curvature changes significantly, i.e., boundary inflection points. These inflection points typically correspond to the turning points, sharp corners, or intersections of curves and straight lines in the pattern contour. The contour segment between two adjacent boundary inflection points is identified as a continuous cutting motion path, and the cutting module 2 does not need to change its direction or make steering adjustments when moving along this path. The control unit counts the total number of all cutting motion paths in the entire target image and determines the motion path density level of the current pattern based on this number—the more paths, the more complex the pattern contour and the denser the inflection points, and the higher the density level. The control unit has a pre-stored mapping table between density level and cutting speed; the higher the density level, the lower the cutting speed of the cutting module 2; the lower the density level, the higher the cutting speed.

[0122] The beneficial effects of this embodiment are significant. First, by identifying boundary inflection points and determining the paths between adjacent inflection points as independent cutting motion paths, the complex image contour is decomposed into several straight or curved motion units with clear start and end points. This segmented processing method provides the cutting module 2 with clear motion trajectory instructions, avoiding the speed planning difficulties caused by excessively long continuous curved paths or sudden curvature changes. This facilitates precise acceleration and deceleration control of the cutting module 2 at inflection points, thereby improving the contour accuracy of the cutting trajectory. Second, by statistically analyzing the number of cutting motion paths to determine the path density level, and adaptively adjusting the cutting speed accordingly, the device can automatically optimize the balance between cutting efficiency and cutting accuracy based on the geometric complexity of the pattern: for simple contours (few paths, low density level), a higher cutting speed is used to improve processing efficiency; for complex contours (many paths, high density level), the cutting speed is automatically reduced to ensure that the cutting module 2 has sufficient time to complete fine turning and contour tracking, avoiding overcutting or contour distortion at corners or sharp angles due to excessive speed. Furthermore, this adaptive speed adjustment mechanism eliminates the need for users to manually set cutting parameters, lowering the barrier to entry for the device and making it particularly suitable for non-professional users in home settings who require processing patterns of varying complexity.

[0123] In some examples, boundary inflection points can be identified using the Douglas-Puk algorithm for contour simplification, or by using curvature extremum detection to identify obvious inflection points. Density levels can be divided into several grades, each corresponding to a different cutting speed.

[0124] In some embodiments, identifying boundary inflection points on the image boundary contour includes:

[0125] Obtain the point sequence of the image boundary contour;

[0126] For any point in the point sequence, construct two vectors based on its preceding and following neighboring points;

[0127] Calculate the angle between two vectors, and identify the point as a boundary inflection point when the angle is less than a preset threshold.

[0128] Understandably, after extracting the image boundary contour of the target image, the control unit represents the contour as an ordered sequence of points, with each point recording its position coordinates in the image coordinate system. For a given point in the point sequence, the control unit selects its previous neighbor (e.g., the k-th point before) and next neighbor (e.g., the k-th point after), constructing a first vector with the current point as the starting point and the previous neighbor as the ending point, and a second vector with the current point as the starting point and the next neighbor as the ending point. These two vectors approximately reflect the trend of the contour curve before and after that point. The control unit calculates the angle between the two vectors—the smaller the angle, the closer the contour's direction before and after that point is to a straight line, and the straighter the curve; the larger the angle, the more significant a turning point the contour has at that point. When the angle is less than a preset threshold (e.g., 150° or 120°), the point is determined to be a boundary inflection point, meaning that the contour exhibits a significant directional change at this point.

[0129] The beneficial effects of this embodiment are significant. First, the algorithm for identifying inflection points by constructing vectors based on neighboring points and calculating the angle between these vectors is simple, efficient, and computationally inefficient, enabling rapid processing of contour data containing a large number of points, making it suitable for the operational requirements of real-time embedded systems. Second, by adjusting the preset threshold, the sensitivity of inflection point recognition can be controlled—a smaller threshold results in more "sharp" inflection points (retaining only obvious turning points) and a higher degree of contour simplification; a larger threshold results in more "gentle" inflection points (retaining more subtle turns) and higher contour accuracy, providing users with flexible parameter configuration space. Third, accurate inflection point recognition allows for more reasonable segmentation of the subsequent cutting motion path. The cutter can perform continuous and smooth movement within each path segment, while at inflection points, it can precisely perform speed adjustments or direction switching, thereby significantly improving the accuracy of the cutting trajectory in following complex contours and avoiding cutting deviations caused by insufficient or excessive contour simplification.

[0130] In some examples, image inflection points can be identified using the corner thresholding method.

[0131] In some examples, the neighboring points can be selected from the 2nd to the 5th points before and after the current point to balance local sensitivity and noise resistance. The preset included angle threshold can be set according to the contour complexity and cutting accuracy requirements. For example, when the threshold is set to 135°, points in the contour with included angles less than 135° are identified as inflection points.

[0132] In some embodiments, the method further includes a cutting depth control step:

[0133] Receives the engraving pressure value input by the user through the control panel or software;

[0134] The cutting module 2 controls the depth of pressure during the cutting operation based on the pressure value of the engraving knife.

[0135] Understandably, the control panel or accompanying software interface of the engraving machine has an input area for the engraving pressure value. Users can input the corresponding engraving pressure value via physical knobs, buttons, or a touchscreen, based on the thickness and hardness of the material to be processed (e.g., thin paper, thick cardboard, leather, or film). This value is usually expressed as a numerical value (e.g., weight) or a range (e.g., 1 to 10 levels). After receiving the engraving pressure value input by the user, the control unit converts it into a control parameter for the depth of cut in the cutting module 2. This is achieved, for example, by adjusting the rotation angle of the motor driving the cutting module 2 or the on / off time of the electromagnet, so that the cutter head cuts into the material at a depth corresponding to the pressure value during the cutting process. The higher the pressure value, the deeper the cutting depth of the cutting module 2; the lower the pressure value, the shallower the cutting depth.

[0136] The benefits of this embodiment are significant. First, by allowing users to manually input the engraving pressure value according to the actual material being processed, the device can adapt to materials of different thicknesses and hardnesses, ensuring that the cutter head can achieve the optimal cutting depth on different materials. Excessive pressure can cause the cutter head to penetrate the bottom of the material and damage the work platform, while insufficient pressure may result in incomplete cutting and material separation. Users can flexibly adjust the pressure value according to the actual processing effect, improving the device's material adaptability and processing reliability. Second, this control method gives users control over the cutting depth adjustment. Users do not need to understand the complex internal pressure adjustment mechanism of the engraving machine; they only need to select the appropriate pressure value based on the material and their experience to complete the depth adjustment, reducing the barrier to entry and operational complexity of the device, making it especially suitable for non-professional applications such as home DIY crafts. Third, by inputting the pressure value through the control panel or software interface, users can quickly complete the settings before processing and conveniently change parameters when switching between different materials, without the need for external tools or mechanical adjustments, greatly improving the ease of use and processing efficiency of the device.

[0137] In some examples, the engraving pressure value can be input via a knob or numeric keypad on the device panel, or via a parameter setting interface in an external device (such as a mobile app or computer software) connected to the engraving machine. The control unit can store the user-inputted engraving pressure value in memory and directly recall it in subsequent processing of the same material, eliminating the need for the user to re-enter it.

[0138] In some embodiments, the printing module 3 includes an inkjet head and an electromagnetically driven sealing cover; the method further includes:

[0139] In standby mode or after printing is complete, the electromagnetic drive seal cover closes to isolate the inkjet head from the outside air.

[0140] Before printing, control the electromagnetic drive to open the sealing cover.

[0141] Understandably, the control unit is electrically connected to the electromagnetic coil of the electromagnetic drive sealing cover. When the engraving machine is in standby mode (e.g., the device is powered on but not performing a printing task) or idle after a printing task is completed, the control unit sends a closing command to the electromagnetic drive sealing cover. The electromagnetic coil is energized or de-energized (depending on the type of solenoid valve), driving the sealing cover to move to a position where it contacts the nozzle surface of the inkjet head, isolating the nozzle orifice from the outside air and preventing the ink from drying and forming a skin at the nozzle opening. When the user initiates the printing operation, the control unit first sends an opening command to the electromagnetic drive sealing cover, driving the sealing cover to move away from the nozzle surface of the inkjet head, exposing the nozzle above the material surface. Then, the printing module 3 begins the ink jetting and printing action. The inkjet head sealing cover and the printing action are synchronized to ensure that the sealing cover opens in time before printing and closes promptly after printing.

[0142] The beneficial effects of this embodiment are significant. First, by controlling the closing of the electromagnetically driven sealing cover after standby or printing, the contact between the inkjet head nozzles and the outside air is effectively isolated, preventing solvent in the ink from evaporating at the nozzle opening and causing the ink to dry, form a skin, and clog the nozzles. This ensures the long-term stability and print quality of the inkjet head and reduces the number of cleaning cycles and ink waste caused by nozzle clogging. Second, the automatic opening of the sealing cover before printing allows the printing module 3 to execute the printing task promptly without requiring the user to manually open or install the sealing cover, achieving fully automated sealing cover control and improving the ease of use of the equipment. Third, the electromagnetically driven sealing cover features fast response and precise control, accurately controlling the opening and closing timing of the sealing cover to ensure it closes immediately after printing, thereby minimizing the time the nozzles are exposed to air.

[0143] In some examples, the electromagnetically driven sealing cap can be an electromagnet-driven lever-type sealing cap or a linear motion sealing cap, with the sealing cap's engagement and disengagement achieved by controlling the on / off state of the electromagnetic coil. The contact surface of the sealing cap can be provided with an elastic sealing gasket (e.g., a silicone gasket) to enhance the sealing effect and protect the nozzle surface from damage by hard contact.

[0144] In some embodiments, the engraving machine has a control component that can execute the engraving machine control method of this application.

[0145] According to the embodiments of the third aspect of this application, such as Figure 8As shown, the electronic device may include: a processor 310, a communication interface 320, a memory 330, and a communication bus 340, wherein the processor 310, the communication interface 320, and the memory 330 communicate with each other via the communication bus 340. The processor 310 can call logical instructions in the memory 330 to execute a cutting machine control method, which includes:

[0146] S100, Obtain the target image;

[0147] S200. Based on the target image, determine the printing coordinate data and cutting coordinate data;

[0148] S300: Based on the print coordinate data, control the print module 3 to move and perform the print operation;

[0149] S400: Based on the cutting coordinate data, control the cutting module 2 to move and perform the cutting operation.
