Description

Technical Field

[0001] This application relates to the field of cutting equipment technology, and in particular to a cutting device, a roll jig, and a printer. Background Technology

[0002] The substrate (e.g., the substrate used for printing) can be a flexible material such as a polymer film (e.g., PET, PP, PE, or PVC film), leather, or textiles. The substrate has a large size before use and is usually rolled into rolls for easy storage and transportation. When using the substrate, it is cut into sections as needed. In related technologies, the substrate is prone to shifting during the cutting process, resulting in uneven and unsightly cut edges. Utility Model Content

[0003] This application provides a cutting device, a roll jig, and a printer, which can solve the technical problem that the substrate is easily displaced during the cutting process.

[0004] To address the aforementioned technical problems, this application provides a cutting device having three different directions: a first direction, a second direction, and a third direction. The cutting device is used to cut a substrate, which is movable relative to the cutting device along the first direction. The cutting device includes: a housing assembly; a cutter guide rail mounted on the housing assembly; a cutter assembly slidably disposed on the cutter guide rail along the second direction, used for cutting the substrate; a first clamping member fixedly disposed on the housing assembly; and a second clamping member movably disposed on the housing assembly and located on the side of the first clamping member in the third direction. The second clamping member is configured to move relative to the first clamping member along the third direction, so that when the cutter assembly cuts the substrate, the second clamping member can cooperate with the first clamping member to clamp and fix the substrate.

[0005] In another aspect, this application provides a roll material fixture, which includes a first transmission component, a second transmission component, and a cutting device as described above. The first transmission component and the second transmission component are mounted on the cutting device. The first transmission component can drive the substrate to move. The first transmission component is closer to the downstream of the substrate moving direction than the second transmission component. The cutting component is disposed close to the first transmission component and is used to cut the substrate output from the first transmission component.

[0006] In another aspect, this application provides a printer, which includes a body, a printhead disposed on the body, and a roll-to-roll fixture as described above. The roll-to-roll fixture is separable from the body, and the printhead is used to perform printing operations on a substrate.

[0007] The cutting device provided in this application includes a first clamping member and a second clamping member. The second clamping member is configured to move relative to the first clamping member in a third direction, so that when the cutting blade assembly cuts the substrate, the second clamping member can cooperate with the first clamping member to clamp and fix the substrate, so that the second clamping member and the first clamping member press the substrate from both sides of the substrate, making it less likely for the substrate to shift during the cutting process, and the cut edge of the substrate can be neater and more aesthetically pleasing.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This application provides a printer for performing printing operations on a substrate. Please refer to [link / reference]. Figure 1 The printer may include a body (not shown), a printhead (not shown) mounted on the body, and a roll-to-roll fixture 100. The roll-to-roll fixture 100 is detachable from the body, facilitating the storage and transport of the printer. The roll-to-roll fixture 100 can move and cut the substrate. The printhead is used to perform printing operations on the substrate. The roll-to-roll fixture 100 is configured to move the substrate so that the printhead can print on different areas of the substrate. The printing operations that the printhead can perform include 2D and 2.5D printing. In 2.5D printing, the inkjet thickness can reach 1 mm. After printing, the roll-to-roll fixture 100 can segment and cut the substrate, thereby dividing the printed substrate into target sizes.

[0026] This application provides a roll material fixture for moving a substrate and performing a cutting operation on the substrate. Please refer to [link to relevant documentation]. Figures 1-5 The roll-to-roll fixture 100 may include a cutting device 50, a first transfer assembly 20, and a second transfer assembly 30. The first transfer assembly 20 and the second transfer assembly 30 are mounted on the cutting device 50. The cutting device 50 is used to cut a substrate. The cutting device 50 may include a housing assembly 10. The housing assembly 10 is used to provide support for other components. The housing assembly 10 may include multiple sub-housings. The first transfer assembly 20 and the second transfer assembly 30 may be mounted on the housing assembly 10. The first transfer assembly 20 can move the substrate to perform related operations on different areas of the substrate. For example, performing a printing operation on the substrate; the following description uses performing a printing operation on the substrate as an example. The first transfer assembly 20 is located downstream of the substrate in the direction of substrate movement relative to the second transfer assembly 30. That is, the first transfer assembly 20 is located near the substrate outlet, and the second transfer assembly 30 is located near the substrate inlet.

[0027] In one embodiment, the first transmission component 20 and the second transmission component 30 are configured to apply a force to the substrate, thereby cooperating to tension the substrate located between the first transmission component 20 and the second transmission component 30 before performing the relevant operation. By cooperating to tension the substrate located between the first transmission component 20 and the second transmission component 30, the substrate becomes flatter, thereby preventing wrinkles from forming on the substrate during the relevant operation.

[0028] In one embodiment, such as Figure 2 , Figure 3As shown, the first transmission assembly 20 includes a first transmission shaft 21 and a first motor 23, with the first transmission shaft 21 and the first motor 23 being drive-connected. The first transmission shaft 21 and the first motor 23 can be connected via a rotating shaft, belt, or gear transmission. The first transmission shaft 21 can be a knurled shaft to increase the friction between the shaft surface and the object being acted upon. The first transmission shaft 21 is rotatably mounted on the housing assembly 10. The substrate can be supported on the first transmission shaft 21. Under the drive of the first motor 23, the first transmission shaft 21 applies a force to the substrate. The direction of the force applied by the first transmission shaft 21 to the substrate can be the same as or opposite to the direction of movement of the substrate. Specifically, when the first transmission shaft 21 rotates forward under the drive of the first motor 23, the direction of the force applied by the first transmission shaft 21 to the substrate is the same as the direction of movement of the substrate; when the first transmission shaft 21 rotates backward under the drive of the first motor 23, the direction of the force applied by the first transmission shaft 21 to the substrate is opposite to the direction of movement of the substrate. The second transmission component 30 may include a suction cup (not shown in the figure), which is installed inside the housing component 10. At the second transmission component 30, the substrate is supported on the housing component 10. When the substrate moves to a preset position, the first transmission shaft 21 rotates forward under the drive of the first motor 23. The direction of the force applied by the first transmission shaft 21 to the substrate is the same as the direction of movement of the substrate. The first transmission shaft 21 applies a pulling force to the substrate, and the suction cup adsorbs the substrate. One end of the substrate is fixed at the second transmission component 30. At this time, the first transmission component 20 and the second transmission component 30 cooperate to tension the substrate, making the substrate flatter and thus preventing wrinkles from appearing on the substrate during the printing process.

[0029] In one embodiment, such as Figure 2 , Figure 3 As shown, the second transmission assembly 30 includes a second transmission shaft 31. The second transmission shaft 31 can be arranged parallel to the first transmission shaft 21. Due to limitations in the manufacturing process, the parallelism or perpendicularity in this application can have a certain deviation, for example, a deviation of ±10°. The second transmission shaft 31 can be a steel spike shaft to increase the friction between the transmission shaft surface and the object being processed. The second transmission shaft 31 is rotatably disposed on the housing assembly 10. The substrate can be supported on the second transmission shaft 31. Compared to the substrate being directly supported on the housing assembly 10, since the second transmission shaft 31 is rotatable, the rolling friction is less than the sliding friction, which can reduce the resistance when the substrate moves. The second transmission shaft 31 can apply a force to the substrate to tension the substrate located between the first transmission shaft 21 and the second transmission shaft 31, making the substrate flatter and thus preventing wrinkles from appearing on the substrate during printing. By setting the second transmission shaft 31 to apply a force to the substrate, compared to the suction cup applying a force to the substrate, the structure of the second transmission assembly 30 is simpler and can reduce costs.

[0030] The second transmission shaft 31 and the first transmission shaft 21 can share a single drive motor. (See also...) Figure 4 In one embodiment, the second transmission assembly 30 includes a transmission belt 34, which drives the second transmission shaft 31 and the first transmission shaft 21. The transmission belt 34 is used to move the substrate, and the second transmission shaft 31 applies a force to the substrate through the transmission belt 34. For example, grooves are spaced apart on the outer peripheral wall of the second transmission shaft 31, and a spring pin is installed on the housing assembly 10. The spring pin abuts against the outer peripheral wall of the second transmission shaft 31. When the second transmission shaft 31 rotates, the spring pin cooperates with the groove wall to change the friction between the second transmission shaft 31 and the transmission belt 34. When the friction between the second transmission shaft 31 and the transmission belt 34 increases, the transmission belt 34 between the first transmission shaft 21 and the second transmission shaft 31 is tightened. The friction between the transmission belt 34 and the substrate causes the substrate attached to the transmission belt 34 to be stretched along with the transmission belt, so that the second transmission shaft 31 can apply a force to the substrate through the transmission belt 34.

[0031] In one embodiment, such as Figure 2 As shown, the second transmission shaft 31 and the first transmission shaft 21 are each equipped with an independent drive motor. The second transmission assembly 30 includes a second motor 33, and the second transmission shaft 31 is drivenly connected to the second motor 33. The second transmission shaft 31 and the second motor 33 can be connected by a rotating shaft, belt, or gear transmission. The second transmission shaft 31 applies a force to the substrate under the action of the second motor 33. The direction of the force applied by the first transmission shaft 21 to the substrate can be the same as or opposite to the direction of movement of the substrate. Specifically, when the second transmission shaft 31 rotates forward under the drive of the second motor 33, the direction of the force applied by the second transmission shaft 31 to the substrate is the same as the direction of movement of the substrate; when the second transmission shaft 31 rotates in the reverse direction under the drive of the second motor 33, the direction of the force applied by the second transmission shaft 31 to the substrate is opposite to the direction of movement of the substrate. During the printing process, when the substrate moves to the preset position, firstly, the first transmission shaft 21 rotates in the reverse direction under the drive of the first motor 23 to retract the material, thereby eliminating the tolerance that occurs during the feeding process; then, the first transmission shaft 21 rotates in the forward direction under the drive of the first motor 23 to feed the material, and the second transmission shaft 31 rotates in the forward direction under the drive of the second motor 33 to feed the material; finally, the first transmission shaft 21 rotates in the forward direction under the drive of the first motor 23, and the direction of the force applied by the first transmission shaft 21 to the substrate is the same as the direction of movement of the substrate, and the first transmission shaft 21 applies tension to the substrate; the second transmission shaft 31 rotates in the reverse direction (or does not rotate) under the drive of the second motor 33, and the direction of the force applied by the second transmission shaft 31 to the substrate is opposite to the direction of movement of the substrate, so that the first transmission component 20 and the second transmission component 30 cooperate with each other to tension the substrate, thereby preventing wrinkles from appearing on the substrate during the printing process.

[0032] The cutting device 50 has a first direction, a second direction, and a third direction that are different from each other. The substrate can move relative to the cutting device 50 along the first direction. Exemplarily, the first direction, the second direction, and the third direction can be perpendicular to each other, wherein the first direction can be... Figure 1 The positive or negative direction of the Y-axis, the second direction can be Figure 1 The positive or negative direction of the X-axis, and the third direction can be Figure 1 The positive or negative direction of the Z-axis.

[0033] The first transmission component 20 may include at least one pressure roller (not shown in the figure). For example, a pressure roller may be provided at each end of the first transmission shaft 21 along the second direction. The pressure roller is used to hold the substrate against the first transmission shaft 21, thereby increasing the friction between the substrate and the first transmission shaft 21.

[0034] Please see Figure 2 , Figure 3 In one embodiment, the first transmission component 20 includes a third transmission shaft 22. The third transmission shaft 22 is arranged parallel to the first transmission shaft 21. The third transmission shaft 22 may be a rubber-coated shaft, thereby increasing the friction between the third transmission shaft 22 and the substrate. A fourth gap 221 is provided between the third transmission shaft 22 and the first transmission shaft 21, through which the substrate passes. The third transmission shaft 22 is used to hold the substrate against the first transmission shaft 21. In the third direction, the third transmission shaft 22 may be disposed above or below the first transmission shaft 21. By setting the third transmission shaft 22 to hold the substrate against the first transmission shaft 21, the substrate can be held against the first transmission shaft 21 as a whole in the second direction relative to the pressure roller, resulting in more uniform force on the substrate and making the substrate flatter.

[0035] Similarly, the second transmission assembly 30 may include at least one pressure roller. For example, a pressure roller may be provided at each end of the second transmission shaft 31 along the second direction, and the pressure roller is used to hold the substrate against the second transmission shaft 31, thereby increasing the friction between the substrate and the second transmission shaft 31.

[0036] In one embodiment, such as Figure 2 , Figure 3As shown, the second transmission assembly 30 includes a fourth transmission shaft 32. The fourth transmission shaft 32 is arranged parallel to the second transmission shaft 31. The fourth transmission shaft 32 may be a rubber-coated shaft, thereby increasing the friction between the fourth transmission shaft 32 and the substrate. A fifth gap 321 exists between the fourth transmission shaft 32 and the second transmission shaft 31, through which the substrate passes. In the third direction, the fourth transmission shaft 32 may be positioned above or below the second transmission shaft 31. The fourth transmission shaft 32 is used to hold the substrate against the second transmission shaft 31, thereby allowing the substrate to be held against the second transmission shaft 31 as a whole in the second direction, resulting in more uniform force distribution on the substrate and a flatter substrate.

[0037] In one embodiment, such as Figure 6 , Figure 8 As shown, the cutting device 50 includes a cutter assembly 51, a cutter guide rail 52, a first clamping member 53, and a second clamping member 54. The cutter guide rail 52 is mounted on the housing assembly 10. The cutter guide rail 52 can extend along a second direction. The cutter assembly 51 is slidably disposed on the cutter guide rail 52 along the second direction. The cutter assembly 51 can be disposed close to the first transmission assembly 20, and the cutter assembly 51 is used to cut the substrate output from the first transmission assembly 20. The first clamping member 53 is fixedly disposed on the housing assembly 10. The second clamping member 54 is movably disposed on the third-direction side of the first clamping member 53. For example, the second clamping member 54 can be slidably connected to the housing assembly 10 along the third direction. The second clamping member 54 is configured to be movable relative to the first clamping member 53 along the third direction so that when the cutter assembly 51 cuts the substrate, the second clamping member 54 can cooperate with the first clamping member 53 to clamp and fix the substrate. The second clamping member 54 is configured to cooperate with the first clamping member 53 to clamp and fix the substrate, so that the second clamping member 54 and the first clamping member 53 press the substrate from both sides, making it less likely for the substrate to shift during the cutting process, and the cut edge of the substrate can be neater and more aesthetically pleasing.

[0038] The cutter guide rail 52 and the cutter assembly 51 can be disposed outside the housing assembly 10. When the cutting device 50 is in manual cutting mode, the user can easily pull the cutter assembly 51 to manually cut the substrate.

[0039] Please see Figure 6In one embodiment, the cutter guide rail 52 and the cutter assembly 51 are disposed inside the housing assembly 10. Since the cutter assembly 51 requires a certain installation space, placing the cutter assembly 51 inside the housing assembly 10 can make full use of the lower space in the height direction (i.e., the third direction) of the housing assembly 10. Compared with placing the cutter assembly 51 outside the housing assembly 10, the total height of the cutting device 50 can be reduced, which is beneficial to reducing the volume of the cutting device 50. In addition, by placing the cutter assembly 51 inside the housing assembly 10, the cutter assembly 51 can cut the substrate from bottom to top, that is, from the unprinted lower surface of the substrate to the printed upper surface. On the one hand, it can prevent the sharp blade from scratching the ink or coating on the upper surface, resulting in image damage and edge curling (curling), which is beneficial to protecting the integrity of the printed layer. On the other hand, when cutting into the unprinted lower surface, the cutting force first acts on the untreated substrate bottom layer and gradually transfers upward to the printed layer. This progressive cutting can disperse stress and reduce stress concentration, thereby avoiding the printed layer from tearing or deforming due to instantaneous force.

[0040] The second clamping member 54 can be connected to a drive motor, which drives the second clamping member 54 to move in a third direction to clamp or release the substrate.

[0041] In one embodiment, the cutter assembly 51 is drive-connected to the second clamping member 54, so that when the cutter assembly 51 slides on the cutter guide rail 52, it can push the second clamping member 54 to move toward the first clamping member 53 in a third direction and clamp and fix the substrate. In the third direction, the second clamping member 54 can be closer to the lower part of the housing assembly 10 relative to the first clamping member 53, so that the cutter assembly 51 can push the second clamping member 54 to move. By setting the cutter assembly 51 to push the second clamping member 54 to move, the second clamping member 54 does not need to be equipped with a drive motor, which can reduce costs. The second clamping member 54 can be reset under its own weight, or an elastic member is provided between the second clamping member 54 and the first clamping member 53, and the second clamping member 54 is reset under the action of the elastic member.

[0042] The second clamping member 54 can be a rod-shaped component extending along the second direction. Correspondingly, the cutter assembly 51 can be provided with an abutment (not shown in the figure), the abutment surface of which contacts the second clamping member 54 is set at an angle to the second direction. When the cutter assembly 51 slides on the cutter guide rail 52, the end of the second clamping member 54 can slide on the abutment surface, so that the abutment can push the second clamping member 54 to move towards the first clamping member 53 along the third direction to clamp and fix the substrate. With this configuration, the second clamping member 54 does not need to be equipped with a drive motor, which can reduce costs.

[0043] Please see Figure 6 , Figure 7In one embodiment, the cutter assembly 51 includes a drive wheel 513. The second clamping member 54 includes a first segment 541 and a second segment 542 connected sequentially along a second direction. The first segment 541 is used to clamp and fix a substrate. The first segment 541 may be rod-shaped and extends along the second direction. The projection of the second segment 542 along a third direction at least partially falls outside the substrate. The side of the second segment 542 near the drive wheel 513 is angled to the side of the first segment 541 near the drive wheel 513, so that as the drive wheel 513 moves from the second segment 542 to the first segment 541, it can push the second clamping member 54 toward the first clamping member 53 along a third direction. The transmission wheel 513 is configured to cooperate with the inclined second section 542 to push the second clamping member 54 to move toward the first clamping member 53 in a third direction. On the one hand, the second clamping member 54 does not need to be equipped with a drive motor, which can reduce costs. On the other hand, the transmission wheel 513 and the second clamping member 54 form rolling friction, which can reduce the resistance when the transmission wheel 513 moves from the second section 542 to the first section 541.

[0044] The second clamping member 54 and the first clamping member 53 can be made of metal, thereby reducing the deformation of the clamping members under stress. Please refer to [link / reference]. Figure 8 In one embodiment, the cutting device 50 includes an elastic clamping member 55, which is strip-shaped or sheet-shaped and is attached to one of a second clamping member 54 and a first clamping member 53. The elastic clamping member 55 can be attached to either the second clamping member 54 or the first clamping member 53. The elastic clamping member 55 can be a silicone strip or a rubber strip. When the cutter assembly 51 slides on the cutter guide rail 52, the elastic clamping member 55 elastically abuts against the surface of the substrate. Providing the elastic clamping member 55 to elastically abut against the surface of the substrate increases the friction between the clamping member and the substrate surface, thereby making the substrate more firmly fixed during cutting and resulting in a neater and more aesthetically pleasing cut edge.

[0045] In one embodiment, such as Figures 10-12 As shown, the cutter assembly 51 includes a cutter 511. The second clamping member 54 can be a single unit. For example, in the first direction, the cutter 511 is further away from the first transmission shaft 21 relative to the second clamping member 54, and one second clamping member 54 cooperates with the first clamping member 53 to clamp the substrate, facilitating cutting by the cutter 511. Alternatively, there may be two sets of second clamping members 54 and transmission wheels 513, such as... Figure 8As shown, two sets of transmission wheels 513 are respectively arranged on both sides of the cutter 511 along the first direction, and two sets of second clamping members 54 have a first gap 546 in the first direction. The first clamping member 53 is provided with a cutting groove 531 corresponding to the first gap 546. When the cutter assembly 51 slides on the cutter guide rail 52, each set of transmission wheels 513 respectively holds the first section 541 of the corresponding second clamping member 54 against the substrate, and a part of the cutter 511 passes through the first gap 546 and the cutting groove 531. The two sets of second clamping members 54 are arranged at intervals in the first direction, which can fix the substrate from both sides of the cutter 511, thereby tensioning the substrate at the first gap 546, making the substrate more firmly fixed during the cutting process, and the cut edge of the substrate can be neater and more beautiful.

[0046] The two sets of second clamping members 54 include a first sub-clamping member 544 near the side where the substrate is inserted and a second sub-clamping member 545 away from the side where the substrate is inserted, such as Figure 8 As shown. The first sub-clamping member 544 and the second sub-clamping member 545 have clamping and releasing positions relative to the first clamping member 53, respectively. In the clamping position, the first sub-clamping member 544 and the second sub-clamping member 545 cooperate with the first clamping member 53 to clamp and fix the substrate, making it difficult for the substrate to shift during cutting. After cutting, the cutter assembly 51 moves on the cutter guide rail 52 to return to the initial position and wait for the next cutting operation. During the movement of the transmission wheel 513 from the corresponding first segment 541 to the second segment 542, the second clamping member 54 can move from the clamping position to the releasing position along the third direction and release the substrate, so that the substrate can freely pass through the gap between the second clamping member 54 and the first clamping member 53 when moving. In the releasing position, in the third direction, the first segment 541 of the first sub-clamping member 544 and the first segment 541 of the second sub-clamping member 545 can be set flush. Alternatively, please refer to Figure 8 In one embodiment, in the release position, within a reference section perpendicular to the second direction, the first segment 541 of the first sub-clamping member 544 and the first clamping member 53 have a second gap 547, and the first segment 541 of the second sub-clamping member 545 and the first clamping member 53 have a third gap 548. The third gap 548 is larger than the second gap 547, so that after the substrate passes through the second gap 547, it can cross the first gap 546 and pass through the third gap 548. With this configuration, in the third direction, the upper surface height of the first segment 541 of the first sub-clamping member 544 is higher than the upper surface height of the first segment 541 of the second sub-clamping member 545. When the substrate passes through the first gap 546, even if the substrate falls downwards under gravity, the first segment 541 of the second sub-clamping member 545 can catch the falling substrate, thereby allowing the substrate to cross the first gap 546 and pass through the third gap 548. This prevents the substrate from falling into the first gap 546, which is beneficial for substrate insertion.

[0047] Please see Figure 6 In one embodiment, each second clamping member 54 further includes a third segment 543 connected to the end of the second segment 542 facing away from the first segment 541. The projection of the third segment 543 in the third direction falls outside the substrate, and the side of the third segment 543 near the drive wheel 513 is parallel to the side of the first segment 541 near the drive wheel 513. The third segment 543 is closer to the first clamping member 53 than the first segment 541. After the cutter assembly 51 returns to its initial position, the drive wheel 513 can abut against the third segment 543. Since the third gap 548 is greater than the second gap 547, the second sub-clamping member 545 has a greater stroke in the third direction than the first sub-clamping member 544. The first clamping member 53 can be configured to be bent upwards to prevent the third segment 543 from interfering with the first clamping member 53 when the second sub-clamping member 545 moves toward the first clamping member 53. Alternatively, as Figure 6 As shown, the first clamping member 53 is provided with a clearance portion 532. At least a portion of the clearance portion 532 is recessed on the side facing away from the second clamping member 54 in a third-order upward direction. In the clamping position, the third segment 543 of the second sub-clamping member 545 is at least partially accommodated in the clearance portion 532. The clearance portion 532 can be a groove formed on the first clamping member 53. By providing a clearance portion to accommodate the third segment 543 of the second sub-clamping member 545, the first clamping member 53 does not need to be bent upward and will not interfere with the third segment 543 of the second sub-clamping member 545. The first clamping member 53 is more regular, which facilitates the processing of the first clamping member 53.

[0048] Within a reference section perpendicular to the first direction, the cross-sectional dimension of the first segment 541 in the third direction can be equal to the cross-sectional dimension of the second segment 542 in the third direction, that is, the second clamping member 54 has a uniform cross-section in the second direction.

[0049] In one embodiment, such as Figure 6 As shown, within a reference cross-section perpendicular to the first direction, at least a portion of the first segment 541 has a cross-sectional dimension in the third direction that is larger than at least a portion of the second segment 542 in the third direction. With this configuration, the second clamping member 54 has a variable cross-section in the second direction, and the first segment 541 has a larger cross-section, which reduces the bending dimension of the second segment 542 and helps to reduce the volume of the cutting device 50.

[0050] Please see Figures 10-12In one embodiment, the cutting assembly 51 includes a cutting blade 511, a cutting blade support 512, a pressure roller support 516, and a first elastic member 517. The cutting blade 511 may be disc-shaped. The cutting blade 511 is mounted on the cutting blade support 512 and rotatably connected to the cutting blade support 512, allowing the cutting blade 511 to rotate relative to the cutting blade support 512. Rolling friction is generated between the cutting blade 511 and the substrate, which can reduce the frictional force between the two, making the cutting operation more labor-saving. The drive wheel 513 is mounted on the pressure roller support 516. The pressure roller support 516 is slidably connected to the cutting blade support 512 along a third direction. The two ends of the first elastic member 517 abut against the pressure roller support 516 and the cutting blade support 512 respectively, so as to elastically hold the drive wheel 513 against the second pressing member 54. The first elastic member 517 may be a spring or other elastic components. The pressure roller bracket 516 is slidably connected to the cutter bracket 512, and a first elastic element 517 is provided between the pressure roller bracket 516 and the cutter bracket 512. Since the first elastic element 517 can generate elastic deformation, it can eliminate the machining tolerance of the parts, thereby better holding the transmission wheel 513 against the second clamping element 54.

[0051] In one embodiment, a Teflon film is provided on the surface of the cutter 511. The Teflon film can cover the entire surface of the cutter 511, or it can only cover a portion of the surface, such as the surface near the blade. The Teflon film is a high-performance fluoroplastic film with polytetrafluoroethylene (PTFE) as its main component. Providing a Teflon film on the surface of the cutter 511 has two advantages: firstly, the Teflon film has an extremely low coefficient of friction (0.05–0.10), which reduces the friction between the cutter 511 and the substrate, making the cutting operation more effortless; secondly, the Teflon film has self-lubricating properties, allowing the surface of the cutter 511 to remain almost completely free of adhering substances, thus preventing powder generated during cutting from adhering to the cutter 511 and affecting the cutting effect.

[0052] In one embodiment, such as Figures 10-13As shown, the cutter assembly 51 includes a cutter 511, a cutter bracket 512, and a cutter mounting member 514. The cutter 511 is mounted on the cutter mounting member 514, and the cutter mounting member 514 is detachably connected to the cutter bracket 512. The cutter mounting member 514 and the cutter bracket 512 can be connected by snap-fit ​​or screws to facilitate the removal or installation of the cutter mounting member 514. The housing assembly 10 includes a housing 11 and a cutter cover plate 14. The housing 11 has a mounting hole 111, and the cutter cover plate 14 is detachably covered by the mounting hole 111. The mounting hole 111 is used for the removal or installation of the cutter mounting member 514 and the cutter 511. The cutter cover plate 14 and the housing 11 can be connected by snap-fit ​​or screws to facilitate the removal or installation of the cutter cover plate 14. The cutter mounting bracket 514 is detachably connected to the cutter support 512, and the cutter cover plate 14 is detachably installed on the mounting hole 111, which facilitates the replacement of the cutter 511 and improves the user experience.

[0053] A jig can be used to hold the cutter mounting piece 514, thereby allowing the cutter 511 to be removed or installed through the mounting hole 111. Alternatively, please refer to... Figure 10 , Figure 11 In one embodiment, the cutter assembly 51 includes a mounting handle 515, which is positioned near the mounting hole 111. One end of the mounting handle 515 is rotatably connected to the cutter mounting member 514, and the other end of the mounting handle 515 is configured to rotate toward the mounting hole 111 and protrude from the housing 11. When disassembling the cutter 511, rotating the mounting handle 515 exposes it from the housing 11. By holding the mounting handle 515, the cutter 511 and the cutter mounting member 514 can be pulled out from the mounting hole 111, thus facilitating the replacement of the cutter 511. When installing the cutter 511, the same method can be used to push the cutter 511 and the cutter mounting member 514 into the mounting hole 111 by holding the mounting handle 515. After the cutter 511 has been replaced, rotating the mounting handle 515 makes it fit tightly against the cutter mounting member 514, which reduces the space occupied by the mounting handle 515 inside the housing assembly 10.

[0054] Please see Figure 9 In one embodiment, the cutting device 50 includes a cutting drive motor 56, which is connected to the cutter assembly 51. The cutting drive motor 56 drives the cutter assembly 51 to slide on the cutter guide rail 52. The cutting drive motor 56 can be connected to the cutter assembly 51 via a belt, a reduction gear set, and an idler gear set. By setting the cutting drive motor 56 to drive the cutter assembly 51 to cut the substrate, the substrate can be automatically cut under the control of a control signal, making substrate cutting more convenient.

[0055] In one embodiment, such as Figure 5As shown, the cutting device 50 includes a cutting handle 57. One end of the cutting handle 57 is connected to the cutter assembly 51, and the other end is exposed outside the housing assembly 10. The other end is used to apply external force to drive the cutter assembly 51 to slide on the cutter guide rail 52. The cutting handle 57 is used to manually cut the substrate by driving the cutter assembly 51. The cost of the cutting handle 57 is relatively low, which can reduce production costs.

[0056] Please see Figure 6 In one embodiment, the cutting device 50 includes a cutter detection element 58, and cutter detection elements 58 are respectively installed at both ends of the cutter guide rail 52. The cutter detection element 58 can be a photoelectric sensor, an infrared sensor, or a Hall sensor. When the cutter assembly 51 slides to a preset position on the cutter guide rail 52, the cutter assembly 51 can trigger the cutter detection element 58 to obtain the position information of the cutter assembly 51. For example, before printing starts, the cutter assembly 51 triggers the cutter detection element 58 at one end of the cutter guide rail 52, indicating that the cutter assembly 51 is in the starting position, the transmission wheel 513 has not pushed the second clamping member 54 to move, there is a gap between the second clamping member 54 and the first clamping member 53, and the substrate can be output from the first transmission shaft 21; when the cutter assembly 51 triggers the cutter detection element 58 at the other end of the cutter guide rail 52, it indicates that the cutter assembly 51 is at the maximum stroke, the substrate cutting has been completed, and the cutter assembly 51 can return to the starting position to wait for the next cutting operation.
