[0006] In the coding system provided in the embodiment of the present application, since there is a gap between the first connecting member and the second connecting member, the vibration of the equipment frame cannot be transmitted to the second connecting member and the nozzle connected to the second connecting member through the coding host and the first connecting member, thereby helping to avoid incomplete or unclear coding.

[0007] In an exemplary embodiment, the coding system further includes: a distance component, which is directly or indirectly connected to the coding host and is configured to contact the side of the material, and the distance component is at least partially located between the side of the material and the coding host, so that the distance between the coding host and the material is kept constant in the width direction of the material. Through this embodiment, in the width direction, the distance between the coding host and the side of the material can be kept constant, which is conducive to maintaining a constant distance between the nozzle linked to the coding host and the side of the material, thereby facilitating avoiding incomplete or unclear coding.

[0008] In an exemplary embodiment, the distance-fixing component includes at least one guide wheel, the central axis of the guide wheel is parallel to the thickness direction of the material, and the guide wheel is directly or indirectly connected to the coding host, so that the central axis of the coding host and the guide wheel remain relatively stationary. Through this embodiment, the guide wheel is tangent to the material, and the distance between the material and the central axis of the guide wheel in the material width direction remains constant; and because the guide wheel is directly or indirectly connected to the coding host, the central axis of the coding host and the guide wheel remain relatively stationary; therefore, the distance between the material and the coding host in the material width direction remains constant, which is conducive to maintaining a constant distance between the nozzle linked to the coding host and the side of the material, and then helps to avoid incomplete or unclear coding.

[0009] In an exemplary embodiment, the inkjet system further includes: a position judgment component, which is arranged upstream of the inkjet printer and is used to judge whether the position of the material is correct; and a power source, which is connected to the inkjet host, the first connecting member also cooperates with the second connecting member in transmission, and the power source is configured to drive the inkjet host to move in the width direction of the material, so as to drive the second connecting member to move in the width direction of the material through the first connecting member, thereby driving the nozzle to move in the width direction of the material. Through this embodiment, when the material position is incorrect, the nozzle can avoid the incorrectly positioned material to avoid collision.

[0010] In an exemplary embodiment, the position determination component includes at least one photoelectric sensor. According to this embodiment, the photoelectric sensor can be used to determine whether the position of the material is correct.

Through this embodiment, the staggered arrangement in the advancing direction can avoid mutual interference between the photoelectric signals of the first photoelectric sensor and the second photoelectric sensor.

Through this embodiment, the arrangement of the lever and the fork can not only prevent the vibration from being transmitted from the lever to the fork through the movable gap, but also realize the linkage of the lever and the fork, so that when the position judgment component judges that the position of the material is incorrect, the lever can drive the fork and thus drive the nozzle to move in the width direction of the material to the side away from the material direction, so that the nozzle avoids the incorrectly positioned material and avoids the occurrence of collision.

This embodiment is conducive to limiting the movement direction of the inkjet head and the inkjet host, so that the inkjet head and the inkjet host can only move along the width direction of the material.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0024] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a coding system, which includes a coding machine, which is configured to be installed on one side of a transmission mechanism for transmitting a material 8, and the coding machine can spray the code on the side of the material 8; the coding machine includes a coding host 11 and a nozzle 12; the coding system also includes a connecting component, the connecting component includes a first connecting member 21 and a second connecting member 22, the first connecting member 21 is fixedly connected to the coding host 11, the second connecting member 22 is fixedly connected to the nozzle 12, and the first connecting member 21 and the second connecting member 22 are clearance-matched to limit the vibration of the coding host 11 from being transmitted to the nozzle 12.

[0025] The coding host 11 is configured to be installed on an equipment rack on one side of the transmission mechanism. If the coding host 11 and the nozzle 12 are rigidly connected, the vibration of the equipment rack will be transmitted to the nozzle 12 through the coding host 11. The rigid connection between the coding host 11 and the nozzle 12 includes, but is not limited to, the coding host 11 is fixedly connected to a support body (e.g., a support rod), and the nozzle 12 is fixed on the support body. Taking this rigid connection method as an example, the vibration of the equipment rack will be transmitted to the support rod through the coding host 11, and the support rod will transmit the vibration to the nozzle 12, resulting in incomplete or unclear coding.

[0026] In the embodiment of the present application, the coding host 11 and the nozzle 12 are connected by a connecting assembly, which includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 is fixedly connected to the coding host 11, and the second connecting member 22 is fixedly connected to the nozzle 12. The first connecting member 21 and the second connecting member 22 are clearance-matched to limit the vibration of the coding host 11 from being transmitted to the nozzle 12. The setting of the connecting assembly is conducive to making the coding host 11 and the nozzle 12 become one, and is conducive to the movement of the two together, without the need to separately control the two to make similar movements.

[0027] Since there is a gap between the first connecting member 21 and the second connecting member 22, the vibration of the equipment frame cannot be transmitted to the second connecting member 22 and the nozzle 12 connected to the second connecting member 22 through the inkjet host 11 and the first connecting member 21, which helps to avoid incomplete or unclear inkjet printing.

[0028] In one example, the coding host 11 and the nozzle 12 can be connected by a hose to transport the ink in the coding host 11 to the nozzle 12. The hose can absorb the vibration of the coding host 11, which is helpful to prevent the vibration of the coding host 11 from being transmitted to the nozzle 12. In one example, the coding host 11 and the nozzle 12 are not connected by a hose, and the nozzle 12 has its own ink cartridge, which is further helpful to prevent the vibration of the coding host 11 from being transmitted to the nozzle 12.

[0029] The coding host 11 and the nozzle 12 are electrically connected to transmit control signals. In one example, the coding host 11 and the nozzle 12 are connected by a wire, which can absorb the vibration of the coding host 11, which is beneficial to prevent the vibration of the coding host 11 from being transmitted to the nozzle 12. In one example, the coding host 11 and the nozzle 12 transmit control signals through a wireless connection, which is further beneficial to prevent the vibration of the coding host 11 from being transmitted to the nozzle 12.

[0030] In one example, the gap between the first connecting member 21 and the second connecting member 22 is 0.5 to 1.5 mm. If the distance is too large, it is not conducive to the linkage between the coding host 11 and the nozzle 12; if the distance is too small, it is not conducive to avoiding the transmission of vibration between the coding host 11 and the nozzle 12.

[0031] In the coding system provided in the embodiment of the present application, due to the gap between the first connecting member 21 and the second connecting member 22, the vibration of the equipment frame cannot be transmitted to the second connecting member 22 and the nozzle 12 connected to the second connecting member 22 through the coding host 11 and the first connecting member 21, thereby helping to avoid incomplete or unclear coding.

[0032] In an exemplary embodiment, the coding system further includes: a distance component, which is directly or indirectly connected to the coding host 11 and is configured to contact the side of the material 8, and the distance component is at least partially located between the side of the material 8 and the coding host 11, so that the distance between the coding host 11 and the material 8 remains constant in the width direction of the material 8.

[0033] Through this embodiment, in the width direction, the distance between the coding host 11 and the side of the material 8 can be kept constant, which is beneficial for maintaining a constant distance between the nozzle 12 linked to the coding host 11 and the side of the material 8, thereby helping to avoid incomplete or unclear coding.

[0034] In an exemplary embodiment, Figure 1 As shown, the distance component includes at least one guide wheel 3, the central axis of the guide wheel 3 is parallel to the thickness direction of the material 8, and the guide wheel 3 is directly or indirectly connected to the coding host 11 so that the central axis of the coding host 11 and the guide wheel 3 remain relatively stationary.

[0035] In this embodiment, the guide wheel 3 can be tangent to the material 8, and during the normal movement of the material 8, it always remains tangent to the material 8, so that the distance between the material 8 and the central axis of the guide wheel 3 in the width direction of the material 8 remains constant.

[0036] In one example, the guide wheel 3 is directly connected to the coding host 11, and both ends of the central axis of the guide wheel 3 are fixed on the coding host 11. This embodiment has a simple structure, which is conducive to simplifying the structural complexity and number of components of the coding system.

[0037] In one example, the guide wheel 3 is indirectly connected to the coding host 11, and the guide wheel 3 is connected to the coding host 11 through a wheel frame, one end of the wheel frame is fixed on the coding host 11, and the other end of the wheel frame is connected to one end of the central axis of the guide wheel 3. This embodiment is conducive to rapid installation and fixation, has fewer requirements for installation space and installation position, is conducive to installation, and the wheel frame can be fixed to the coding host 11 by point, line or surface, and the fixing point of the wheel frame and the coding host 11 can be arbitrarily selected on the outer shell of the coding host 11.

[0038] Through this embodiment, the guide wheel 3 is tangent to the material 8, and the distance between the material 8 and the central axis of the guide wheel 3 in the width direction of the material 8 remains constant; and because the guide wheel 3 is directly or indirectly connected to the coding host 11, the central axis of the coding host 11 and the guide wheel 3 remain relatively stationary; therefore, the distance between the material 8 and the coding host 11 in the width direction of the material 8 remains constant, which is conducive to maintaining a constant distance between the nozzle 12 linked to the coding host 11 and the side of the material 8, which in turn helps to avoid incomplete or unclear coding.

[0039] In an exemplary embodiment, Figure 1 As shown, the inkjet coding system also includes: a position judgment component, which is arranged upstream of the inkjet printer and is used to judge whether the position of the material 8 is correct; and a power source 7, which is connected to the inkjet coding host 11, and the first connecting member 21 is also in transmission cooperation with the second connecting member 22. The power source 7 is configured to drive the inkjet coding host 11 to move in the width direction of the material 8, so as to drive the second connecting member 22 to move in the width direction of the material 8 through the first connecting member 21, thereby driving the nozzle 12 to move in the width direction of the material 8.

[0040] The position determination component determines that the position of the material 8 is correct. At this time, the power source 7 does not provide power to the inkjet printer host 11 .

[0041] The position judgment component judges that the position of the material 8 is incorrect. At this time, the power source 7 provides power to the inkjet printer 11, that is, the power source 7 drives the inkjet printer 11 to move in the width direction of the material 8 to the side away from the material 8.

[0042] The movement of the inkjet host 11 drives the first connecting member 21 to move in the width direction of the material 8 toward the side away from the material 8, thereby driving the second connecting member 22 that cooperates with the first connecting member 21 to move in the width direction of the material 8 toward the side away from the material 8, and then drives the nozzle 12 fixedly connected to the second connecting member 22 to move in the width direction of the material 8 toward the side away from the material 8, so that the nozzle 12 avoids the material 8 that is not in the correct position to avoid collision.

[0043] The incorrect position of the material 8 includes both the material 8 warping up and the material 8 breaking.

[0044] The power source 7 includes but is not limited to a cylinder.

[0045] Through this embodiment, when the position of the material 8 is incorrect, the nozzle 12 can avoid the incorrectly positioned material 8 to avoid the occurrence of collision.

[0046] In an exemplary embodiment, the position determination component includes at least one photoelectric sensor 4 .

[0047] Through this embodiment, the photoelectric sensor 4 can be used to determine whether the position of the material 8 is correct.

[0048] In one example, the photoelectric sensor 4 includes a transmitting part and a receiving part, and the transmitting part and the receiving part are respectively located on both sides of the width direction of the material 8. When the material 8 passes through, the receiving part cannot receive the photoelectric signal emitted by the transmitting part due to the obstruction of the material 8, thereby being able to determine the position where the material 8 passes through the photoelectric sensor 4.

[0049] In an exemplary embodiment, the number of the photoelectric sensors 4 is two, and the two photoelectric sensors 4 are respectively a first photoelectric sensor and a second photoelectric sensor: wherein the first photoelectric sensor and the second photoelectric sensor are staggered in the advancing direction of the material 8 .

[0050] In one example, under normal circumstances, the first photoelectric sensor can sense the passage of material 8. When the size of material 8 does not change and the transmission speed of the transmission mechanism does not change, when material 8 passes, the time for material 8 to block the first photoelectric sensor is constant. When the blocking time period changes, especially when the blocking time period becomes shorter, it can be determined that material 8 is broken. Broken material 8 is relatively easy to be misaligned. At this time, the inkjet host 11 can drive the nozzle 12 to move in the width direction of material 8 to the side away from the material 8 to prevent material 8 from colliding with the nozzle 12.

[0051] Through this embodiment, the staggered arrangement in the forward direction can avoid mutual interference between the photoelectric signals of the first photoelectric sensor and the second photoelectric sensor.

[0052] In an exemplary embodiment, the first photoelectric sensor and the second photoelectric sensor are arranged to be staggered in the thickness direction of the material 8 .

[0053] In one example, the second photoelectric sensor is arranged to be installed above the first photoelectric sensor. Under normal circumstances, the first photoelectric sensor can sense the passage of the material 8, but the second photoelectric sensor cannot sense the passage of the material 8. When the second photoelectric sensor senses the passage of the material 8, but the first photoelectric sensor cannot sense the passage of the material 8, it can be known that the material 8 is tilted upward. At this time, the inkjet host 11 can drive the nozzle 12 to move in the width direction of the material 8 to the side away from the material 8 to prevent the material 8 from colliding with the nozzle 12.

[0054] Through this implementation, the staggered arrangement in the thickness direction is helpful to determine whether the material 8 is warped.

[0055] In an exemplary embodiment, the first connecting member 21 is a shift rod, and the second connecting member 22 is a shift fork. The shift fork is plugged into the shift rod, and there is a movable gap between the shift rod and the shift fork along the width direction of the material 8. The extension direction of the shift rod is parallel to the forward direction of the material 8. The shift fork includes two shift paddles, which are located on both sides of the shift rod.

[0056] In one example, if Figure 1 and Figure 2 As shown, the two paddles of the shift fork are parallel to each other, and the vertical lines of the two paddles are parallel to the width direction of the material 8.

[0057] In one example, there is a 0.5 to 1.5 mm clearance between each paddle and the lever. If the clearance is too large, it is not conducive to the linkage between the inkjet host 11 and the nozzle 12; if the clearance is too small, it is not conducive to avoiding the transmission of vibration between the inkjet host 11 and the nozzle 12.

[0058] The lever can push the paddle, thereby driving the shift fork to move together. When the position judgment component determines that the position of the material 8 is incorrect, at this time, the power source 7 provides power to the inkjet printer 11, that is, the power source 7 drives the inkjet printer 11 to move in the width direction of the material 8 to the side away from the material 8. The movement of the inkjet printer 11 drives the lever to move in the width direction of the material 8 to the side away from the material 8, thereby driving the shift fork that cooperates with the lever to move in the width direction of the material 8 to the side away from the material 8, and then drives the nozzle 12 fixedly connected to the shift fork to move in the width direction of the material 8 to the side away from the material 8, so that the nozzle 12 avoids the incorrectly positioned material 8 to avoid collision.

[0059] Through this implementation, the setting of the lever and the fork can not only prevent the vibration from being transmitted from the lever to the fork through the movable gap, but also realize the linkage between the lever and the fork. Therefore, when the position judgment component judges that the position of the material 8 is incorrect, the lever can drive the fork and thus drive the nozzle 12 to move to the side away from the material 8 in the width direction of the material 8, so that the nozzle 12 avoids the incorrectly positioned material 8 to avoid the occurrence of collision.

[0060] In an exemplary embodiment, the inkjet coding system further includes a first linear limit assembly and a second linear limit assembly. The first linear limit assembly cooperates with the nozzle 12 to limit the movement of the nozzle 12 and is configured to guide the nozzle 12 to move along the width direction of the material 8. The second linear limit assembly cooperates with the inkjet coding host 11 to limit the movement of the inkjet coding host 11 and is configured to guide the inkjet coding host 11 to move along the width direction of the material 8.

[0061] This embodiment is helpful to limit the moving direction of the nozzle 12 and the coding host 11, so that the nozzle 12 and the coding host 11 can only move along the width direction of the material 8.

[0062] In an exemplary embodiment, the first linear limit assembly is a linear bearing 51 assembly, which includes a linear bearing 51 and a linear guide rod 52. The linear bearing 51 can slide along the linear guide rod 52, and the linear guide rod 52 extends along the width direction of the material 8; the nozzle 12 and the second connecting member 22 are fixedly connected to the linear bearing 51, and both ends of the linear guide rod 52 are fixed on the nozzle bracket 6.

[0063] In one example, the nozzle bracket 6 is configured to be installed on the floor of a factory building instead of on an equipment rack, so as to prevent the vibration of the equipment rack from being transmitted to the nozzle bracket 6 and then to the nozzle 12 through the nozzle bracket 6 .

[0064] The linear bearing 51 has low friction, is stable and sensitive, and can enable the nozzle 12 to move smoothly.

[0065] This embodiment helps the nozzle 12 to move more sensitively and smoothly.

[0066] In an exemplary embodiment, the second linear limit assembly is a slide rail assembly, which includes a slide rod and a slider. The slider can slide along the slide rod, and the slide rod extends along the width direction of the material 8; the slider is fixedly connected to the inkjet host 11 to drive the inkjet host 11 to slide along the slide rod.

[0067] Through this embodiment, the slide rail assembly is more conducive to reducing costs compared to sensitive components such as the linear bearing 51.
