[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The embodiment of the present application discloses a blade printer.

[0031] Reference Figure 1 The blade printer includes a frame 1 and a reeling and unreeling device, a conveying device, a laser marking device and a dust recovery device installed on the frame 1.

[0032] The frame 1 is a steel frame structure, and the frame 1 is arranged along a straight line.

[0033] The rewinding and unwinding device uses multiple sets of motors, rewinding rollers and unwinding rollers to coordinate and stably pull the blade belt at the front and rear ends of the blade belt.

[0034] The conveying device is used to cooperate with the reeling and unreeling device to convey the blade belt along the straight line layout direction of the frame 1.

[0035] Specifically, the conveying device includes a first conveying roller group 2 and a second conveying roller group 3 which are sequentially arranged along the linear arrangement direction of the frame 1 .

[0036] In the embodiment of the present application, the first conveyor roller group 2 and the second conveyor roller group 3 are both composed of two groups of conveyor rollers arranged up and down. The blade belt passes through the gap between the two groups of conveyor rollers in the first conveyor roller group 2 and the gap between the two groups of conveyor rollers in the second conveyor roller group 3 in sequence, and moves forward steadily from the first conveyor roller group 2 toward the second conveyor roller group 3 along with the winding and unwinding device.

[0037] It should be noted that, in other feasible schemes, the first conveying roller group 2 and the second conveying roller group 3 can also be composed of more than two groups of conveying rollers arranged up and down, and can also be composed of multiple groups of conveying rollers arranged in an offset manner; the first conveying roller group 2 and the second conveying roller group 3 only need to be able to stably convey the blade belt and keep the blade belt in horizontal transmission below the working end of the laser marking device.

[0038] Furthermore, in the embodiment of the present application, the laser marking device includes a laser marking machine 4 fixedly disposed between the first conveying roller group 2 and the second conveying roller group 3 .

[0039] Specifically, the body of the laser marking machine 4 is fixedly installed on the frame 1. The laser marking machine 4 generates a laser beam carrying character information through a laser scanning system, and images the laser beam through an electronic photography system and transfers it to the blade belt, forming corresponding fonts and patterns on the surface of the blade; at the same time, the blade belt is driven to move forward stably by the distance of a single blade during each working interval of the laser marking machine 4 through the reeling and unreeling device and the conveying device, so as to realize automatic printing on the surface of the blade belt.

[0040] During this process, the laser beam is emitted in the vertical direction. When the blade belt passes under the working end of the laser marking machine 4, the blade belt is arranged horizontally, and the upper surface of the blade belt is perpendicular to the emission direction of the laser beam. Protective plates are fixedly installed on both sides of the frame 1. The protective plates can effectively protect, filter, cut off and absorb lasers of specific wavelengths, thereby effectively protecting against laser radiation. At the same time, the laser marking process does not require the blade to be baked and cured, which greatly improves the printing efficiency of the blade printer on the blade belt.

[0041] Furthermore, the dust recovery device includes a dust collecting trough 5 and an exhaust assembly 6.

[0042] The dust collecting trough 5 is located below the laser marking machine 4 , and the dust collecting trough 5 is a linear trough box, and the linear extension direction of the dust collecting trough 5 is consistent with the linear extension direction of the frame 1 .

[0043] The exhaust assembly 6 includes an exhaust fan 61 , an air suction hood 62 and a connecting pipe 63 .

[0044] The exhaust fan 61 is fixedly installed on the frame 1, and four groups of air hoods 62 and connecting pipes 63 are arranged in the embodiment of the present application. The number of air hoods 62 and connecting pipes 63 in each group of air hoods 62 and connecting pipes 63 is consistent and one-to-one corresponding. The four groups of air hoods 62 and connecting pipes 63 are evenly distributed on the working end side of the laser marking machine 4, and two groups of air hoods 62 and connecting pipes 63 are located above the blade belt, and the other two groups of air hoods 62 and connecting pipes 63 are located below the blade belt. The inlet of each air hood 62 is arranged toward the working end of the laser marking machine 4, and the outlet is connected to the exhaust fan 61 through the corresponding connecting pipe 63.

[0045] It should be noted that in other application embodiments, the air suction hood 62 and the connecting pipe 63 can also be set to two groups, three groups or more than four groups. The air suction hood 62 and the connecting pipe 63 only need to play a role in guiding the flow from the surface of the blade belt to the suction end of the exhaust fan 61.

[0046] Furthermore, in the embodiment of the present application, the dust hood is configured to be a flared type, and the opening radius of the end of the dust hood close to the connecting pipe 63 is smaller than the opening radius of the end away from the connecting pipe 63, so as to expand the suction area of ​​the dust hood; the connecting pipe 63 is configured to be a threaded pipe, and the connecting pipe 63 includes a threaded pipe body and a metal fixing wire, which is threadedly wound around the pipe body, and the metal fixing wire has a certain ductility. The operator can bend the connecting pipe 63 according to the actual working conditions, thereby adaptively adjusting the distance between the connecting pipe 63 and the dust hood and the blade belt, and the angle between the dust hood and the blade belt, so as to efficiently and comprehensively realize the dust collection processing between the laser marking machine 4 and the blade belt.

[0047] Furthermore, a brush roller 7 is provided between the exhaust assembly 6 and the second conveying roller group 3 , and an industrial camera 8 is provided between the brush roller 7 and the second conveying roller group 3 . The industrial camera 8 is connected to an image recognition processing device.

[0048] The brush roller 7 is located above the dust collecting trough 5, and the brush roller 7 specifically includes an upper roller body and a lower roller body. The upper roller body is located above the blade belt, and the lower roller body is located below the blade belt. The upper roller body and the lower roller body are both rotatably installed on the frame 1, and the upper roller body and the lower roller body are both parallel to the conveying roller. The surface of the brush roller 7 is in contact with the surface of the blade belt; as the blade belt moves forward steadily with the conveying device, the brush roller 7 can sweep the dust remaining on the surface of the blade belt into the dust collecting trough 5, and further clean the dirt in the printing area on the blade surface.

[0049] The industrial camera 8 cooperates with the image recognition and processing device to collect and identify images of the blade belt surface, thereby effectively controlling the printing quality of the blade belt surface, further ensuring the clarity and stability of the printed pattern, and improving the production quality of the blade.

[0050] The implementation principle of a blade printer in an embodiment of the present application is as follows: in the process of marking the surface of the blade, the blade printer of the present application realizes the stable forward movement of the blade belt through the reeling and winding device and the conveying device, and marks the blades in the blade belt one by one through the laser marking machine 4 in this process, and the surface of the blade belt below the laser marking machine 4 is sucked by the dust recovery device at the peripheral side of the working end of the laser marking machine 4, so as to effectively collect and remove the dust and exhaust gas diffused around the blade belt, clean the dirt in the printing area of ​​the blade surface, and further ensure the clarity and stability of the printed pattern.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
