[0038] As Figures 1-4 The present application provides an optical fiber laser online inkjet printer, which is arranged above the conveying surface of the conveying device 200, and comprises a mounting frame 110, a sliding rail 120, an inkjet head 130 and a first driving assembly.

[0039] The mounting bracket 110 is U-shaped and is mounted above the conveying device 200. Two mounting brackets 110 are provided, spaced apart along the conveying direction of the conveying device 200. Both ends of the slide rail 120 are fixedly connected to the mounting bracket 110. The spray nozzle 130 is located below the slide rail 120 and is slidably connected to the slide rail 120, allowing the spray nozzle 130 to reciprocate linearly along the conveying direction of the conveying device 200.

[0040] The first drive component is mounted on the mounting bracket 110. During inkjet printing, the first drive component drives the inkjet header 130 to move along the conveying direction of the conveying device 200, and the moving speed of the inkjet header 130 is equal to the conveying speed of the conveying device 200. After inkjet printing is completed, the first drive component drives the inkjet header 130 to move quickly back to the initial position.

[0041] During inkjet printing, when the material moves to the area below the inkjet printing head 130, the first drive component drives the inkjet printing head 130 to move along the conveying direction of the conveying component, and makes the moving speed of the inkjet printing head 130 consistent with the conveying speed of the conveying device 200, so that the inkjet printing head 130 and the material remain relatively stationary, thereby facilitating inkjet printing.

[0042] After the inkjet printing is completed, the first drive component drives the inkjet nozzle 130 to quickly return to its initial position for the next inkjet printing.

[0043] The fiber laser online inkjet printer provided in this embodiment has a simple structure and reasonable design. It can achieve the purpose of inkjet printing on materials without stopping the conveyor device 200, thus improving work efficiency.

[0044] like Figure 1 As shown, the first drive assembly includes a slider 141, a lead screw 142, and a first motor 143.

[0045] A slider 141 is disposed at the bottom of the guide rail and is slidably connected to the guide rail. A spray nozzle 130 is fixedly disposed at the bottom of the slider 141. A lead screw 142 is rotatably connected to the guide rail. The slider 141 is sleeved on the lead screw 142, and when the lead screw 142 rotates, it drives the slider 141 to move. A first motor 143 is fixedly disposed on the mounting bracket 110. The power output shaft of the first motor 143 is connected to the lead screw 142 to drive the lead screw 142 to rotate. Specifically, when the first motor 143 rotates in the forward direction, it drives the slider 141 to move along the conveying direction of the conveying device 200 via the lead screw 142; when the first motor 143 rotates in the reverse direction, it drives the slider 141 to rotate in the opposite direction via the lead screw 142.

[0046] The first driving component in this embodiment has a simple structure and a reasonable design.

[0047] As Figure 1 , 4 shown in the embodiment, the fiber laser online inkjet printer further comprises a controller 151, a roller 152 and a detection module 153.

[0048] The controller 151 is electrically connected with the inkjet assembly and the first driving assembly. The roller 152 is arranged at the bottom of the sliding block 141, and the roller 152 is rotationally connected with the sliding block 141. The detection module 153 is arranged on the sliding block 141.

[0049] The detection module 153 is used for detecting the rotating direction and rotating speed of the roller 152, and converting the detected information into corresponding electrical signals and transmitting the electrical signals to the controller 151. The controller 151 is used for converting the received electrical signals into corresponding control signals to control the running state of the first motor 143 and the inkjet head 130.

[0050] Specifically, when the detection module 153 detects that the roller 152 rotates in the reverse direction, it indicates that the moving speed of the inkjet printer (the sliding block 141) is slow, and the controller 151 controls the first motor 143 to increase the rotation; when the detection module 153 detects that the roller 152 rotates in the reverse direction, it indicates that the moving speed of the inkjet head 130 (the sliding block 141) is fast, and the controller 151 controls the first motor 143 to reduce the rotation; when the detection module 153 detects that the rotating speed of the roller 152 is zero, it indicates that the moving speed of the inkjet printer (the sliding block 141) is equal to the conveying speed of the conveying device 200, and the controller 151 controls the inkjet head 130 to jet ink.

[0051] In the embodiment, the controller 151, the roller 152 and the detection module 153 are arranged to facilitate the control of the motion state of the first motor 143 and the inkjet head 130.

[0052] As Figure 4 shown, the detection module 153 comprises a rotating speed sensor 101 and a rotating direction sensor 102 arranged on the sliding block 141. The rotating speed sensor 101 is used for detecting the rotating speed of the roller 152, and the rotating direction sensor 102 is used for detecting the rotating direction of the roller 152.

[0053] As Figure 1 , 2 shown, the detection module 153 comprises a rotating speed sensor 101 and a rotating direction sensor 102 arranged on the sliding block 141. The rotating speed sensor 101 is used for detecting the rotating speed of the roller 152, and the rotating direction sensor 102 is used for detecting the rotating direction of the roller 152.

[0054] The pressing plate 161 is slidably connected with the sliding block 141, so that the pressing plate 161 can move longitudinally. The first end of the elastic element 162 is connected with the sliding block 141, and the second end is connected with the pressing plate 161. In the natural state, the elastic element 162 exerts an elastic force on the pressing plate 161, so that the pressing plate 161 has a downward movement tendency. In the embodiment, the elastic element 162 is a spring. In other embodiments, the elastic element 162 can also be any component capable of exerting an elastic force on the pressing plate 161, such as a hydraulic spring, a pneumatic spring, a rubber spring, etc.

[0055] Preferably, the pressing plate 161 is in the shape of a snowshoe, so as to facilitate the material passing through.

[0056] Preferably, the bottom of the pressing assembly and the outer side of the roller 152 are provided with rubber pads, so as to increase the friction between the roller 152 and the pressing assembly and the material.

[0057] In the specification of the utility model, a large number of specific details are explained. However, it can be understood that the embodiments of the utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail, so as not to obscure the understanding of the specification.

[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should be covered in the scope of the claims and the specification of the utility model.
