[0027] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0028] Please refer to Figure 1 and 2 , the present invention provides a printer with a self-flattening roller, including a support frame 1, a cross beam 2, a nozzle assembly 3 and a self-flattening roller 4. Among them, the inside of the support frame 1 is hollow, and a printing platform 11 is arranged on the support frame 1, and printing materials are placed on the printing platform 11; the cross beam 2 is arranged above the support frame 1, and the cross beam 2 moves along the X-axis direction of the plane under the action of the first driving assembly; the nozzle assembly 3 is slidably installed on the cross beam, and the nozzle assembly 3 moves along the Y-axis direction of the plane under the action of the second driving member; the self-flattening roller 4 is arranged below the cross beam, and the bottom of the self-flattening roller 4 can be in contact with the printing platform 11, so as to flatten the printing materials.

[0029] During the printing process, the self-flattening roller 4 flattens the printing materials as the cross beam moves, realizing the function of dynamic flattening, ensuring the flatness of the printing materials, so as to always ensure a stable and consistent printing distance and improve the printing quality.

[0030] Furthermore, the number of the self-flattening rollers 4 can be one or more.

[0031] Furthermore, the self-flattening roller 4 includes a "冂"-shaped bracket 41 and a roller 42 rotatably installed between the brackets.

[0032] Furthermore, the self-flattening roller 4 also includes an elastic member, and the elastic member is arranged between the bracket and the crossbeam.

[0033] For details, please refer to the attached manual. Figure 3 and 4 The elastic member is a spring sheet 43 , one end of which is connected to the cross beam, and the other end of which is connected to the bracket 41 . A through groove 26 matching the self-flattening roller 4 is provided at the bottom of the cross beam.

[0034] Under the action of the spring sheet 43, the self-flattening roller 4 can adjust its height according to the thickness of the material, and rise and fall in the through slot 26, so as to realize dynamic adjustment for different printing materials and ensure that the printing materials are always flattened. In addition, the pressure of the self-flattening roller 4 on the printing material can be adjusted by the angle of the spring sheet 43, which is very practical.

[0035] For further reference, Figure 2 Both ends of the crossbeam 2 are respectively provided with crossbeam brackets 21 extending into the support frame 1, and two first synchronous belts 12 along the X-axis direction are provided inside the support frame 1. The two crossbeams are respectively connected with the two first synchronous belts 12, and the first synchronous belts 12 are driven by the first motor.

[0036] The inner bottom wall of the support frame 1 is provided with two slide rails along the X-axis direction, and the two beam brackets 21 are respectively slidably matched with the slide rails. A synchronous belt fixing clip 22 is provided in the middle of the two beam brackets 21, and the beam bracket 21 is connected to the corresponding first synchronous belt 12 through the synchronous belt fixing clip 22.

[0037] By driving the beam along the X-axis direction with two synchronous belts, the beam can be kept parallel and not easily deviated to one side, making printing more stable and accurate.

[0038] Furthermore, a data line guide tube 5 is provided between the two crossbeam brackets 21, and openings for the data line to enter and exit are provided at both ends of the data line guide tube 5. The data line guide tube 5 can guide the path position of the data line to prevent the data line from being entangled and damaged in the support frame 1, and the data line guide tube 5 can strengthen the crossbeam and the crossbeam bracket 21, provide structural strength, and prevent the crossbeam from being deformed.

[0039] Furthermore, the interior of the crossbeam is hollow, and a guide rail 23 is provided on the crossbeam along the Y-axis direction. The nozzle assembly 3 is slidably connected to the guide rail 23. The second driving member includes a second synchronous belt 24 arranged parallel to the guide rail 23 and a second motor driving the second synchronous belt 24 to rotate. The nozzle assembly 3 is cooperatively connected with the second synchronous belt 24.

[0040] By providing the guide rail 23, a natural limit can be provided for the extreme position of the nozzle assembly 3, thereby controlling the displacement distance of the nozzle assembly 3 and ensuring its safe movement range.

[0041] A set of limit blocks 25 are also provided above the crossbeam to further limit the moving position of the nozzle assembly 3 .

[0042] Furthermore, the nozzle assembly 3 includes a nozzle bracket and a nozzle (not shown in the figure).

[0043] The utility model sets a self-flattening roller under the movable crossbeam. During the printing process, the self-flattening roller flattens the printing material as the crossbeam moves, realizing the dynamic flattening function, ensuring the flatness of the printing material, thereby always ensuring a stable and consistent printing distance, and improving the printing quality. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
