Description

Technical Field

[0001] This utility model belongs to the field of cutting machine technology and relates to a dual-track printing and cutting machine. Background Technology

[0002] With the increasing demand for consumer-grade processing such as personalized stickers, labels, cardstock, and heat transfer materials, printing and cutting equipment that can complete pattern printing and contour cutting within the same device is gradually being used. Such equipment typically includes a feeding mechanism for driving the movement of the material to be processed, a printhead module for performing the printing operation, and a cutting head module for performing the cutting operation.

[0003] In existing printing and cutting equipment, the printhead module and the cutting head module can be mounted on the same moving carrier. While this structure allows for the sharing of guiding and driving mechanisms, it increases the mass of the moving carrier. The printhead module and the cutting head module can only move synchronously, making it difficult to design them separately according to the high-speed, low-inertia characteristics required for printing operations and the rigidity and load-bearing capacity required for cutting operations. Furthermore, vibrations and debris generated during cutting operations can also affect the printhead module.

[0004] Another type of device places the printhead module and the cutting head module on two separate moving carriers on the same sliding axis. Since the two moving carriers are on the same movement path and cannot cross each other, appropriate stopping, maintenance, and clearance distances need to be reserved at the ends of the sliding axis to ensure that both the printhead and cutting head modules can cover the effective processing width of the material to be processed. The end space required by the two moving carriers tends to accumulate sequentially along the extension direction of the sliding axis, resulting in a large overall size of the device along the processing width direction, which is detrimental to the miniaturization of desktop consumer devices.

[0005] In addition, relatively large drive components such as cutting drive motors and feeding drive motors are usually located on the side of the main support, and the drive components and corresponding transmission structures can easily further increase the lateral dimensions of the equipment.

[0006] Therefore, there is a need for a printing and cutting device that has independent printing and cutting mechanisms, can cover essentially the same processing width, and can reduce the spatial overlap of various motion modules and their driving components in the lateral direction of the device. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of the existing technology by providing a dual-track printing and cutting machine. This solution addresses the problem that the motion performance of the existing print head module and cutting head module is mutually restricted when they share a moving carrier, and that the parking, maintenance, and clearance space accumulates along the lateral direction of the equipment when using coaxial dual moving carriers, resulting in a large lateral dimension of the entire machine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A dual-track printing and cutting machine, comprising: The main support frame is provided with a worktable for supporting the material to be processed, and the material to be processed can be fed along a first direction. The first sliding shaft and the second sliding shaft are spaced apart on the main body support along the first direction and are respectively located above the worktable. The first sliding shaft and the second sliding shaft are parallel to each other and both extend along a second direction perpendicular to the first direction. The printhead module is slidably mounted on the first sliding shaft and can reciprocate along the second direction under the drive of the print drive mechanism to perform printing operations on the material to be processed; The cutting head module is slidably mounted on the second sliding shaft and can reciprocate along the second direction under the drive of the cutting drive mechanism to perform cutting operations on the material to be processed; Wherein, the printing operation area of ​​the print head module and the cutting operation area of ​​the cutting head module are projected along the first direction.

[0009] Furthermore, the worktable is provided with two limiting bars extending along the first direction. The two limiting bars are spaced apart along the second direction and together define a feeding channel. The limiting bars are used to restrict the material to be processed from shifting along the second direction.

[0010] Furthermore, a first feeding roller and a second feeding roller are rotatably mounted on the main support. Both the first feeding roller and the second feeding roller extend along the second direction and are spaced apart along the first direction. The first feeding roller and the second feeding roller are connected by a transmission belt so that the first feeding roller and the second feeding roller rotate synchronously and have the same circumferential linear velocity on their outer circumferential surfaces, thereby jointly driving the material to be processed to reciprocate along the first direction.

[0011] Furthermore, the main support is provided with a tensioning device, which abuts against the transmission belt and is configured to adjust the tension of the transmission belt so that the transmission belt remains taut.

[0012] Furthermore, the tensioning device includes a tensioning wheel assembly, a positioning plate, a guide post, and an adjusting screw; The tensioning wheel assembly is fixedly connected to the guide post, the guide post slides through the positioning plate, and the tensioning wheel assembly abuts against the transmission belt; The adjusting screw is threadedly connected to the positioning plate, and one end of the adjusting screw abuts against the tension wheel assembly, so as to adjust the position of the tension wheel assembly relative to the positioning plate by rotating the adjusting screw.

[0013] Furthermore, the worktable surface is provided with clearance openings corresponding to the first feeding roller and the second feeding roller respectively. The first feeding roller and the second feeding roller are both located below the worktable surface, and a portion of their outer peripheral surfaces protrude from the worktable surface through the corresponding clearance openings. Paper pressing assemblies are respectively provided above the first feeding roller and the second feeding roller, and the paper pressing assemblies cooperate with the corresponding feeding rollers to clamp the material to be processed.

[0014] Furthermore, the main support includes two side plates arranged opposite each other along the second direction, the first sliding shaft and the second sliding shaft are connected between the two side plates, and a central mounting space is formed by spacing along the first direction; The cutting drive mechanism includes a cutting drive motor, and the feeding mechanism includes a feeding drive motor. The motor body of the cutting drive motor and the motor body of the feeding drive motor are both located between the first sliding shaft and the second sliding shaft along the first direction, and between the two side plates along the second direction.

[0015] Furthermore, the cutting drive mechanism includes a cutting drive motor, a drive wheel, a reversing wheel, and a cutting transmission belt. The drive wheel is connected to the output end of the cutting drive motor. The cutting transmission belt is wound around the drive wheel and the reversing wheel, and after its extension direction is changed by the reversing wheel, it is connected to the cutting head module for transmission.

[0016] Furthermore, both the cutting drive motor and the feeding drive motor are stepper motors.

[0017] Furthermore, the printing drive mechanism includes a printing drive motor, a printing transmission assembly, and a position detection assembly; The main support frame has a bottom mounting space below the worktable, and the print drive motor is located in the bottom mounting space and is connected to the print head module through the print transmission assembly. The position detection component includes a grating ruler extending along the second direction and a reader disposed on the printhead module. The reader is configured to read the grating ruler to detect the position of the printhead module along the second direction.

[0018] This invention achieves this by arranging the first and second sliding shafts at intervals along the feeding direction of the material to be processed, allowing the print head module and the cutting head module to move along independent sliding shafts, and ensuring that the projections of the printing and cutting work areas along the feeding direction coincide. This allows the print head module and the cutting head module to cover essentially the same processing width. Furthermore, the staggered arrangement of the two sliding shafts in the feeding direction reduces the cumulative stopping and clearance space required by the two modules along the extension direction of the sliding shafts.

[0019] Other features and advantages of the present invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the present invention can be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

Detailed Implementation

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] As shown in the attached figures, this embodiment provides a dual-track printing and cutting machine 100, which is mainly used for printing and cutting paper, self-adhesive materials, label materials, thermal transfer materials, cardboard, or other sheet or strip materials to be processed. The dual-track printing and cutting machine 100 includes a main support 10, a first sliding shaft 20, a second sliding shaft 30, a print head module 40, a cutting head module 50, and a feeding mechanism 60 for driving the movement of the materials to be processed. The main support 10 forms the basic load-bearing structure of the entire machine and is used to install printing, cutting, feeding, and transmission components.

[0028] The main support 10 includes two side plates 11 arranged opposite each other along a second direction, with a worktable 12 between the two side plates 11. The worktable 12 is used to support the material to be processed and provides a relatively flat base for the material to move and be processed. The material to be processed can be fed and unfed relative to the worktable 12 along a first direction, where the first direction is the feeding direction of the material and the second direction is a transverse processing direction perpendicular to the first direction. For ease of understanding, in this embodiment, the first direction can be understood as the front-back direction of the equipment, and the second direction can be understood as the left-right direction of the equipment. However, the above directions are only relative definitions based on the normal placement state of the equipment and are not used to limit the actual installation direction of the equipment.

[0029] The first sliding shaft 20 and the second sliding shaft 30 are connected between the two side plates 11 and are respectively located above the worktable surface 12. The first sliding shaft 20 and the second sliding shaft 30 are spaced apart along a first direction, are parallel to each other, and both extend along a second direction. The printhead module 40 is slidably disposed on the first sliding shaft 20, and the cutting head module 50 is slidably disposed on the second sliding shaft 30. Thus, the printhead module 40 and the cutting head module 50 are not jointly mounted on the same moving carrier, nor are they arranged one after the other on the same sliding shaft, but are respectively mounted on two independent sliding shafts that are staggered along the feeding direction.

[0030] In this embodiment, the "dual track" mainly refers to the first sliding shaft 20 and the second sliding shaft 30 being arranged at an interval in the first direction, respectively supporting the print head module 40 and the cutting head module 50. The first sliding shaft 20 and the second sliding shaft 30 have corresponding extension ranges in the second direction, enabling the print head module 40 and the cutting head module 50 to respectively cover the main processing width of the material to be processed. When the print head module 40 performs a printing operation along the first sliding shaft 20, it forms a printing operation area; when the cutting head module 50 performs a cutting operation along the second sliding shaft 30, it forms a cutting operation area. The projections of the printing operation area and the cutting operation area along the first direction coincide.

[0031] The printing and cutting operation areas referred to here are the effective lateral ranges corresponding to the actual processing of the material by the printhead module 40 and the cutting head module 50, excluding the additional movement ranges traversed by the printhead module 40 when entering the printhead maintenance position, the cutting head module 50 when entering the origin detection position, and the two modules during reset, maintenance, or limit detection in non-operational states. The term "projection coincidence along the first direction" means that, when viewed from the first direction, the start and end positions of the printing and cutting operation areas correspond to each other in the second direction, enabling the printhead module 40 and the cutting head module 50 to cover substantially the same lateral processing range, rather than indicating that the first sliding axis 20 and the second sliding axis 30 are located at the same position in three-dimensional space.

[0032] Existing structures that mount the printhead and cutter head modules on the same carriage, while allowing them to share the guide shaft and lateral drive mechanism, require both modules to move synchronously with the carriage. The printhead typically demands low mass, rapid acceleration response, and smooth high-speed reciprocating motion, while the cutter head needs to withstand the resistance generated when the cutter contacts the material, placing relatively higher demands on structural rigidity and driving torque. Mounting both modules together increases the carriage mass and causes printing and cutting performance to mutually restrict each other. Vibrations, paper scraps, or material debris generated during cutting can also adversely affect the printhead.

[0033] Another configuration involves mounting the printhead module and the cutter head module on two separate carriages along the same guide shaft. Since the two carriages are on the same path, they cannot cross each other in the same lateral direction. To ensure both carriages cover the full processing width, appropriate stopping, avoidance, or maintenance distances need to be reserved on both sides of the work area. The end space required by the two carriages tends to accumulate sequentially along the width of the equipment, thus increasing the overall size of the equipment along this second direction.

[0034] In this embodiment, by staggering the first sliding shaft 20 and the second sliding shaft 30 along the first direction, the printhead module 40 and the cutting head module 50 each have independent movement paths. Even if the printhead module 40 and the cutting head module 50 move to the same coordinate position in the second direction, direct collisions between them will not occur due to the gap between them in the first direction. Therefore, the parking, maintenance, and obstacle avoidance areas required by the printhead module 40 and the cutting head module 50 can be overlapped in the second direction, without having to be arranged sequentially along the width of the equipment. This design reduces the lateral footprint of the machine by utilizing the structural hierarchy in the front-to-back direction of the equipment to achieve a reduction in the size of the equipment in the left-to-right direction, while ensuring that the printing and cutting operation areas are basically consistent.

[0035] The printhead module 40 and the cutting head module 50 are each mounted on an independent sliding shaft, allowing the two motion mechanisms to be designed independently according to different process requirements. The printhead module 40 can use a relatively lightweight motion carrier suitable for high-speed scanning and a corresponding transmission mechanism; the cutting head module 50 can use a relatively rigid motion carrier and transmission mechanism capable of withstanding cutting resistance. During operation, the printhead module 40 and the cutting head module 50 do not need to drive the other module in ineffective motion, which helps reduce motion inertia, drive load, and operating noise, and also helps reduce the direct transmission of cutting vibration to the printhead module 40.

[0036] The printhead module 40 is driven by a print drive mechanism. The print drive mechanism includes a print drive motor 41, a print transmission assembly 42, and a position detection assembly. The print transmission assembly 42 may include a drive wheel, a driven wheel, and a print transmission belt. The printhead module 40 is fixedly connected to the print transmission belt. The print drive motor 41 drives the print transmission belt, thereby causing the printhead module 40 to reciprocate along the first sliding shaft 20. The print transmission assembly 42 may also employ a gear and rack, a lead screw and nut, or other transmission methods capable of driving the printhead module 40 to move in a second direction.

[0037] The main support 10 forms a bottom mounting space 13 below the worktable 12, and the print drive motor 41 is housed within this space. During printing, the print head module 40 typically does not need to directly overcome the resistance generated by the cutter entering the material; its lateral movement load is relatively stable, and response speed and smoothness are paramount. Therefore, the print drive motor 41 can be a relatively small motor with a high response speed. Placing the print drive motor 41 in the bottom mounting space 13 below the worktable 12 utilizes the lower space of the main support 10, avoiding the need to mount the print drive motor 41 on the outside of the side plate 11, which would increase the device width, and also lowers the device's center of gravity.

[0038] The position detection component includes a grating ruler 43 extending along a second direction and a reader 44 disposed on the printhead module 40. The grating ruler 43 may be a grating strip, coded band, or other linear coded element with periodic coded information, and the reader 44 may be a photoelectric reader that cooperates with the grating ruler 43. When the printhead module 40 moves along the first sliding axis 20, the reader 44 moves synchronously with the printhead module 40 and continuously reads the coded information on the grating ruler 43. The control system determines the actual position of the printhead module 40 along the second direction based on the position signal output by the reader 44, and controls the running speed, direction of movement, and inkjet timing of the print drive motor 41 accordingly.

[0039] By cooperating with the grating ruler 43, the print drive motor 41 can provide continuous position feedback for the printhead module 40 while using a smaller print drive motor 41. This ensures that the inkjet action corresponds to the actual lateral position of the printhead module 40, reducing printing position errors caused by belt elasticity, inertia, or changes in motor speed. This structure embodies the design philosophy of selecting the drive method and position detection method based on the characteristics of the printing process. It utilizes a smaller motor to achieve high-speed lateral drive and provides actual position feedback through the grating ruler 43, without simply relying on increasing the motor size or increasing the holding torque to ensure the printing position.

[0040] The cutting head module 50 is driven by a cutting drive mechanism. The cutting drive mechanism includes a cutting drive motor 51, a drive wheel 52, a reversing wheel 53, and a cutting transmission belt 54. The cutting head module 50 is fixedly connected to a section of the cutting transmission belt 54. The output end of the cutting drive motor 51 is connected to the drive wheel 52. The cutting transmission belt 54 is wound around the drive wheel 52 and the reversing wheel 53, and its extension direction is changed by the reversing wheel 53 before it is arranged along the extension direction of the second sliding shaft 30. When the cutting drive motor 51 drives the drive wheel 52 to rotate, the drive wheel 52 drives the cutting transmission belt 54 to run, and the cutting transmission belt 54 further drives the cutting head module 50 to reciprocate along the second sliding shaft 30.

[0041] The reversing pulley 53 is mainly used to change the routing path of the cutting drive belt 54, so that the installation position of the cutting drive motor 51 does not have to be on the same straight line as the linear motion path of the cutting head module 50. Depending on the transmission path and wrap angle requirements, the reversing pulley 53 can be one, two, or more. The reversing pulley 53 can be used only as a freely rotating guide wheel, or in a specific structure it can also serve to tension or increase the wrap angle between the cutting drive belt 54 and the drive pulley 52. ​​The cutting drive belt 54 is preferably a synchronous belt to reduce the possibility of relative slippage between the drive pulley 52 and the cutting drive belt 54.

[0042] After the first sliding shaft 20 and the second sliding shaft 30 are spaced apart along the first direction, a central mounting space 14 is formed between the two sliding shafts. The motor body of the cutting drive motor 51 is located between the first sliding shaft 20 and the second sliding shaft 30 along the first direction, and between the two side plates 11 along the second direction. Conventional cutting mechanisms usually place the cutting drive motor at the end of the sliding shaft or on the outside of the side plate, and the motor length, drive wheel, and corresponding mounting base will extend outwards from the equipment, increasing the size of the main support along the second direction. In this embodiment, the cutting drive motor 51 is housed in the central mounting space 14, and the extension direction of the cutting transmission belt 54 is changed by the reversing wheel 53, so that the cutting drive motor 51 located inside the main support 10 can still drive the cutting head module 50 to complete the complete cutting stroke along the second direction.

[0043] Therefore, the reversing wheel 53 is not simply used to change the direction of the drive belt, but rather forms a compact transmission scheme together with the built-in layout of the cutting drive motor 51. After the cutting drive motor 51 is moved from its traditional position on the outside of the side plate to between the first sliding shaft 20 and the second sliding shaft 30, the original linear transmission path of the cutting drive belt 54 needs to be adjusted accordingly. By setting the reversing wheel 53, the power of the cutting drive motor 51 can first be transmitted along the first path within the central mounting space 14, and then, after being changed in direction by the reversing wheel 53, transmitted along the direction of the second sliding shaft 30 to the cutting head module 50. This reduces the lateral space occupied by the cutting drive motor 51 while maintaining the effective working area of ​​the cutting head module 50.

[0044] The feeding mechanism 60 includes a first feeding roller 61, a second feeding roller 62, a transmission belt 63 for connecting the first feeding roller 61 and the second feeding roller 62, and a feeding drive motor 64. Both the first feeding roller 61 and the second feeding roller 62 are rotatably mounted on the main support 10 and extend along a second direction. The first feeding roller 61 and the second feeding roller 62 are spaced apart along a first direction and can be located on opposite sides of the printing and cutting positions, or adjacent to the printing and cutting positions, thereby driving and constraining the material to be processed at different feeding positions.

[0045] The feeding drive motor 64 is connected to one of the first feeding roller 61 and the second feeding roller 62, which are connected by a transmission belt 63. The feeding drive motor 64 can first drive one of the feeding rollers to rotate via a gear set, drive belt, or coupling structure, and then the transmission belt 63 transmits the power to the other feeding roller. Therefore, the first feeding roller 61 and the second feeding roller 62 are mechanically synchronized, rather than being two independent feeding motors.

[0046] In this embodiment, the outer circumferential surfaces of the first feeding roller 61 and the second feeding roller 62 have the same circumferential linear velocity. The term "same circumferential linear velocity" means that the tangential velocity of the first feeding roller 61 and the second feeding roller 62 at the contact position with the material to be processed is the same in magnitude and the feeding direction is consistent. To achieve the same circumferential linear velocity, the first feeding roller 61 and the second feeding roller 62 can be set to have the same outer diameter, and the transmission wheels connected to them can be set to have the same effective transmission diameter, so that they have the same rotational speed; alternatively, if the outer diameters of the two feeding rollers are different, by matching the corresponding transmission wheel diameter or number of teeth, the two feeding rollers can form a transmission relationship with different rotational speeds but the same outer circumferential linear velocity.

[0047] If the circumferential linear velocities of the front and rear feed rollers are different, the material to be processed may be stretched or compressed between the two feeding positions. When the speed of the front feed roller is higher, the material may be stretched or pulled between the two rollers, or slip relative to one of the rollers; when the speed of the rear feed roller is higher, the material may arch or accumulate locally between the two rollers. These phenomena will affect the positional stability of the material to be processed along the first direction, and further affect the registration accuracy of the printed pattern and the cutting path. This embodiment uses mechanical synchronous transmission and makes the outer circumferential linear velocities of the two feed rollers the same, so that the material to be processed receives a basically consistent driving speed at the two feeding positions, which helps to reduce material stretching, arching, skewness, and relative slippage.

[0048] The motor body of the feeding drive motor 64 is also located within the central mounting space 14, specifically between the first sliding shaft 20 and the second sliding shaft 30 along the first direction, and between the two side plates 11 along the second direction. The feeding drive motor 64 needs to drive the feeding clamping structure formed by the two feeding rollers and the paper pressing assembly, and needs to move the material to be processed in the forward or reverse direction along the first direction during printing and cutting; therefore, it typically requires a large driving torque. The cutting drive motor 51 also needs to overcome the lateral resistance generated by the cutting tool cutting the material. In this embodiment, both the cutting drive motor 51 and the feeding drive motor 64 can be stepper motors.

[0049] Stepper motors can move in steps according to control pulses, and have good low-speed torque and position holding capabilities, making them suitable for cutting trajectory control and material reciprocating feeding control. However, compared to the printing drive motor 41, the cutting drive motor 51 and the feeding drive motor 64 are usually larger in size. If both are arranged on the outside of the two side plates 11, the width of the device along the second direction will be significantly increased. In this embodiment, the cutting drive motor 51 and the feeding drive motor 64 are housed in the central mounting space 14 formed between the first sliding shaft 20 and the second sliding shaft 30, so that the two larger stepper motors are located inside the main support 10; at the same time, the smaller printing drive motor 41 is arranged in the bottom mounting space 13 below the worktable 12, thus forming a motor mounting structure with a layered arrangement in the middle and bottom.

[0050] The aforementioned motor layout is not merely an arbitrary adjustment of the positions of different components, but rather a coordinated design with the dual-track structure. The first sliding shaft 20 and the second sliding shaft 30 are staggered along the first direction, eliminating the mutual obstruction between the print head module 40 and the cutting head module 50 on the same transverse movement path, and creating a usable central mounting space 14 between them. The cutting drive motor 51 and the feeding drive motor 64 are housed within this central mounting space 14, allowing the drive components that would otherwise occupy the outer side of the side plate to be moved inside the main support 10. Adjusting the transmission path of the cutting drive belt 54 via the reversing wheel 53 further resolves the issue of the power output position of the built-in cutting drive motor 51 not being aligned with the movement path of the cutting head module 50. This forms a continuous design logic of "staggered front and rear dual tracks, internal motor housing, and reversing transmission paths."

[0051] To ensure stable and synchronized movement of the first feed roller 61 and the second feed roller 62, a tensioning device 70 is also provided on the main support 10. The tensioning device 70 abuts against the transmission belt 63 and is used to adjust the tension of the transmission belt 63, maintaining it at a suitable tension. The tensioning device 70 can be positioned at the slack side of the transmission belt 63 to reduce the additional impact of the tensioning pulley on power transmission.

[0052] The tensioning device 70 includes a tensioning wheel assembly 71, a positioning plate 72, a guide post 73, and an adjusting screw 74. The positioning plate 72 is fixedly mounted on the main support 10 or one of the side plates 11. The tensioning wheel assembly 71 is fixedly connected to the guide post 73, which slides through the positioning plate 72. The tensioning wheel assembly 71 moves relative to the positioning plate 72 with the guide post 73, and the tensioning wheel in the tensioning wheel assembly 71 abuts against the transmission belt 63. The adjusting screw 74 is threadedly connected to the positioning plate 72, and one end of the adjusting screw 74 abuts against the tensioning wheel assembly 71 or abutting part fixedly connected to the tensioning wheel assembly 71.

[0053] When the adjusting screw 74 is rotated, the adjusting screw 74 generates axial displacement relative to the positioning plate 72, and pushes the tensioning wheel assembly 71 to move along the guide direction of the guide post 73, thereby changing the pressure position and degree of the tensioning wheel assembly 71 on the transmission belt 63. The guide post 73 can limit the movement direction of the tensioning wheel assembly 71, reducing the possibility of deflection of the tensioning wheel assembly 71 during adjustment. Through the tensioning device 70, manufacturing dimensional errors, installation errors, and elongation caused by long-term use of the transmission belt 63 can be compensated, reducing slackness, skipping teeth, slippage, or transmission impact of the transmission belt 63, and maintaining the synchronous relationship between the first feed roller 61 and the second feed roller 62.

[0054] The worktable 12 is provided with clearance openings 121 corresponding to the first feed roller 61 and the second feed roller 62, respectively. The main body of the first feed roller 61 and the second feed roller 62 is located below the worktable 12, and a portion of their outer peripheral surfaces protrudes from the worktable 12 through the corresponding clearance openings 121. This structure allows the worktable 12 to provide a large area of ​​planar support for the material to be processed, and also allows the first feed roller 61 and the second feed roller 62 to directly contact the lower surface of the material to be processed.

[0055] Paper pressing assemblies 65 are respectively provided above the first feeding roller 61 and the second feeding roller 62. The paper pressing assemblies 65 cooperate with the corresponding feeding rollers to clamp the material to be processed. The paper pressing assembly 65 may include a paper pressing rod extending along a second direction and multiple paper pressing wheels or paper pressing parts disposed on the paper pressing rod. The multiple paper pressing parts are spaced apart along the second direction and apply a clamping force to the corresponding feeding roller, so that the material to be processed is pressed between the paper pressing part and the feeding roller. When the feeding roller rotates, its outer peripheral surface drives the material to be processed to move along the first direction through friction.

[0056] The paper clamping assembly 65 can employ an elastic element to apply clamping force, or it can be configured to lift and press down to facilitate the loading of the material to be processed. The clamping force should be sufficient to ensure a stable frictional drive between the feed roller and the material to be processed, while avoiding indentations on the surface of the material or increased feeding resistance due to excessive clamping force. Since the first feed roller 61 and the second feed roller 62 clamp and drive the material to be processed at different positions, the material to be processed can maintain a relatively stable flat state between the printing position and the cutting position, reducing the possibility of material displacement caused by the movement of the cutting tool.

[0057] The worktable 12 is also provided with two limiting bars 122 extending along a first direction. The two limiting bars 122 are spaced apart along a second direction and together define a feeding channel 123. The material to be processed is placed in the feeding channel 123, and the two limiting bars 122 respectively restrict the material to be processed from shifting to both sides along the second direction, so that the material to be processed passes through the printing position and the cutting position along the predetermined first direction.

[0058] The limiting stop 122 can be fixedly mounted on the worktable 12, or at least one limiting stop 122 can be configured to be adjustable in position along the second direction to accommodate materials of different widths to be processed. For the position-adjustable limiting stop 122, its position can be adjusted by a sliding groove, a locking knob, or a snap-fit ​​structure. The two limiting stops 122 do not need to continuously clamp the material to be processed; their spacing can be slightly larger than the width of the material to be processed, so as to limit significant lateral displacement of the material while avoiding excessive friction.

[0059] During operation, the material to be processed is first placed in the feeding channel 123 of the worktable 12, and then enters between the paper pressing assembly 65 and the corresponding feeding roller. After the feeding drive motor 64 starts, it drives one of the first feeding roller 61 and the second feeding roller 62 to rotate. The transmission belt 63 synchronously transmits power to the other feeding roller, so that the two feeding rollers rotate at the same peripheral linear speed. The material to be processed moves along the first direction under the combined action of the two sets of feeding rollers and the paper pressing assembly 65.

[0060] Once the area to be printed moves to the position corresponding to the printhead module 40, the feeding mechanism 60 stops the material to be processed or moves it at a predetermined step distance according to the printing control requirements. The print drive motor 41 drives the printhead module 40 to reciprocate and scan along the second direction. The reader 44 continuously reads the grating ruler 43 to obtain the actual lateral position of the printhead module 40. The control system controls the printhead to spray ink at the corresponding position based on the printed image information and the position information of the printhead module 40, and uses the feeding mechanism 60 to gradually move the material to be processed along the first direction, thereby forming a predetermined image on the material to be processed.

[0061] After printing, the material to be processed does not need to be removed from the equipment, nor does it need to be re-attached or re-clamped. The feeding mechanism 60 continues to drive the material to be processed along the first direction, so that the printed material area reaches the cutting position corresponding to the cutting head module 50. Since the material to be processed is always driven by the same set of first feeding rollers 61 and second feeding rollers 62 during printing and cutting, and is laterally constrained by the limiting stop 122, its longitudinal movement reference and lateral feeding reference remain consistent.

[0062] During the cutting operation, the cutting drive motor 51 drives the cutting head module 50 to move along the second direction via the drive wheel 52, the cutting transmission belt 54, and the reversing wheel 53. The feeding drive motor 64 drives the material to be processed to move forward or backward along the first direction. By coordinating the lateral movement of the cutting head module 50 with the longitudinal movement of the material to be processed, the cutter can cut the material according to a predetermined two-dimensional contour path. The cutting can be a partial cut that severs the surface material while retaining the backing paper, or a full cut that penetrates the material, depending on the cutter structure, cutter pressure, and type of material to be processed.

[0063] Since the projections of the printing and cutting areas along the first direction coincide, the lateral range that the print head module 40 can print corresponds to the lateral range that the cutting head module 50 can cut. By feeding the same area of ​​the material to be processed through the same printing and cutting positions sequentially via the feeding mechanism 60, the printed pattern can be contour-cut. Compared to solutions that separate the printer and cutting machine, this embodiment reduces the skew and positional errors introduced by manual material handling, repositioning, and secondary positioning after printing.

[0064] The main technical problem of this embodiment is not merely combining printing and cutting functions into the same device, but rather coordinating the installation and movement relationships between the printhead module 40, cutting head module 50, feeding mechanism 60, and multiple drive motors within a limited desktop device space. If the printhead module 40 and cutting head module 50 share a carriage, it will lead to increased moving mass and mutual constraints between the two process performances; if the two modules share a sliding shaft, it will cause the stopping and avoidance distances to accumulate in the width direction of the device; if the cutting drive motor 51 and the feeding drive motor 64 are still arranged on the outside of the side plate 11 in the traditional way, the lateral compactness advantage obtained by the dual-track structure will be offset by the motors and transmission components.

[0065] Therefore, in this embodiment, the printhead module 40 and the cutting head module 50 are respectively positioned on the first sliding shaft 20 and the second sliding shaft 30, which are offset along the feeding direction. This allows the two modules to have overlapping working projections in the second direction, and allows the space required for stopping, maintenance, and avoidance to be staggered along the first direction. Furthermore, the central mounting space 14 formed between the first sliding shaft 20 and the second sliding shaft 30 is used to house the relatively large cutting drive motor 51 and the feeding drive motor 64. The reversing wheel 53 is used to solve the problem of changing the transmission path after the cutting drive motor 51 is built in. For the relatively small print drive motor 41, which is more focused on high-speed response, it is arranged in the bottom mounting space 13 below the worktable 12, and the position of the printhead module 40 is detected by the grating ruler 43 and the reader 44.

[0066] Therefore, the dual-track structure, motor layout, and transmission path in this embodiment are not isolated from each other. The dual-track structure forms a central mounting space 14, which provides internal mounting positions for the cutting drive motor 51 and the feeding drive motor 64. The reversing wheel 53 enables the built-in cutting drive motor 51 to continue driving the cutting head module 50 moving in the second direction, while the printing drive motor 41 utilizes the bottom mounting space 13 to further avoid occupying the shaft end area. Through the coordination of the above spatial layers, the cumulative size of the printing head module 40, cutting head module 50, cutting drive motor 51, and feeding drive motor 64 in the second direction can be reduced, allowing the entire machine to have a smaller lateral size while maintaining an effective processing width.

[0067] The synchronous feeding structure of the first feeding roller 61 and the second feeding roller 62 also matches the dual-track layout. The printhead module 40 and the cutting head module 50 are located at different positions, and the material to be processed needs to move back and forth between the two processing positions. If the feeding roller is set in only one place, the end of the material away from the feeding position is easily affected by cutting resistance or material warping; if the front and rear feeding rollers are driven by independent motors, the speed difference between the two motors may cause material stretching or arching. In this embodiment, a single feeding drive motor 64 and a transmission belt 63 are used to mechanically synchronize the two feeding rollers and make the circumferential linear speed of their outer surfaces the same, thereby implementing consistent feeding drive for the material to be processed at both the front and rear positions.

[0068] In other embodiments, the front-to-back order of the first sliding shaft 20 and the second sliding shaft 30 can be interchanged. That is, the printhead module 40 can be located on the feeding side or the discharge side of the cutting head module 50, as long as the first sliding shaft 20 and the second sliding shaft 30 are spaced apart along the first direction, and the projections of the printing operation area and the cutting operation area along the first direction coincide. The first sliding shaft 20 and the second sliding shaft 30 are not necessarily limited to a single cylindrical shaft; they can be composed of one or more guide rods, linear guides, or other guide structures that can limit the movement of the printhead module 40 and the cutting head module 50 along the second direction.

[0069] In other embodiments, the printing and cutting work areas may completely overlap, or they may have non-substantial differences due to the edge allowance of the print head, the safety distance of the cutting blade, or equipment assembly errors. In this embodiment, it is preferable to make the start and end positions of their effective work areas in the second direction consistent, so that the printing and cutting areas are matched. The print head module 40 and the cutting head module 50 may still have independent docking, maintenance, or inspection sections outside their effective work areas; these non-work areas do not affect the determination of the projection relationship between the printing and cutting work areas.

[0070] In other embodiments, the cutting drive motor 51 and the feeding drive motor 64 can both be located within the central mounting space 14, or only the main body of the motor can be located within the central mounting space 14, while the output shaft, drive pulley, or transmission components connected to it extend to a position near the side plate 11. The cutting transmission belt 54 can change its extension direction once via a reversing pulley 53, or it can form a zigzag or multi-segment transmission path via multiple reversing pulleys. As long as the cutting drive motor 51 can be housed between the two side plates 11 and its power can be transmitted to the cutting head module 50, it falls under the built-in drive and reversing transmission concept embodied in this embodiment.

[0071] In other embodiments, the print drive motor 41 can be a DC motor, a brushless motor, or other motors suitable for high-speed response. The position detection components are not limited to the grating ruler 43 and the photoelectric reader 44; they can also be magnetic gratings, linear encoders, or other detection structures capable of detecting the position of the print head module 40 along the second direction. In this embodiment, the grating ruler 43 and the reader 44 are used because they can provide continuous position detection with a small installation space, which is beneficial for forming a compact print drive mechanism in conjunction with the bottom-mounted print drive motor 41.

[0072] In other embodiments, the drive belt 63 and the cutting drive belt 54 can be synchronous belts, toothed belts, or other flexible transmission components. The first feed roller 61 and the second feed roller 62 can also form a synchronous transmission via gear sets, drive shafts, or chains, as long as they can achieve the same feed linear speed at the point of contact with the material to be processed. The structure of the tensioning device 70 can also be adjusted, for example, by continuously pushing the tension wheel assembly 71 with a spring, or by adjusting the position of the tension wheel with an eccentric shaft. However, the structure using the adjusting screw 74 and guide post 73 has the advantages of precise adjustment, stable installation, and ease of maintenance.

[0073] In summary, this embodiment is based on a double-track layout where the printhead module 40 and the cutting head module 50 are staggered along the first direction, so that their effective working areas project to coincide along the first direction. This ensures the printing and cutting area while reducing the accumulation of parking, maintenance, and clearance space for the two modules in the second direction. The central mounting space 14 formed between the double tracks is used to house the cutting drive motor 51 and the feeding drive motor 64, and the reversing wheel 53 is used to change the path of the cutting transmission belt 54, reducing the protrusion of the motor to the outside of the side plate 11. The print drive motor 41 is set in the bottom mounting space 13, and the position of the printhead module 40 is detected by the grating ruler 43. The first feeding roller 61 and the second feeding roller 62, which have the same outer circumferential linear velocity, jointly drive the material to be processed to move back and forth, so that the material to be processed stably passes through the printing position and the cutting position in sequence. The above structure collectively solves the problems of mutual constraints between motion modules, accumulation of parking space, increased machine width due to external drive motor, and asynchronous front and rear feeding in integrated printing and cutting equipment. This results in a compact, high-utilization-area processing machine with stable feeding and independent printing and cutting.
