[0043] In the related art, the printing device is often connected with the print head through the driving module, so that the print head can move along the required direction relative to the printing material under the driving of the driving module, to realize the pattern printing function of the print head. Since the connection stability of the driving module and the print head is not high in this kind of setting mode, the print head lacks sufficient rigid support when performing long-stroke printing, so there is a risk that the print head will be out of position due to large shaking amount, which affects the printing precision of the print head.

[0044] Therefore, based on the above consideration, the utility model provides a driving module 100 applied to an inkjet printing device 1000, the inkjet printing device 1000 comprising a print head 200, the driving module 100 provided by the utility model can improve the printing stability of the print head 200, and guarantee the printing precision of the print head 200.

[0045] Next, the structure of the driving module 100 proposed in the application is explained and described in the embodiments. Please refer to Figures 1 to 5 In an embodiment of the utility model, the driving module 100 comprises a rack 10, a driving module 20, a position detection module 30 and a guide rail module 40, the driving module 20 is arranged on the rack 10, and is used for driving connection with the print head 200, to drive the print head 200 to move along the first direction; the position detection module 30 is arranged on the rack 10, and is used for detecting the position of the print head 200; the guide rail module 40 is arranged on the rack 10 and extends along the first direction, and is used for connecting and cooperating with the print head 200.

[0046] The rack 10 can be used to form a mounting base of the functional modules such as the drive module 20, the position detection module 30 and the guide rail module 40. For example, one side of the rack 10 can form a mounting surface 111 with a certain bearing area, and the drive module 20, the position detection module 30 and the guide rail module 40 can be arranged on the mounting surface 111. The rack 10 can also be connected and matched with an external mounting structure such as a housing of a printing device to realize mounting and fixation of the drive module 100.

[0047] In some embodiments, the drive module 20 and the guide rail module 40 can be arranged side by side on the rack 10 and are both connected and matched with the print head 200. The drive module 20 can be but is not limited to a synchronous belt 213 drive module 20, a lead screw drive module 20 or other linear drive modules 20. By drivingly connecting the drive module 20 with the print head 200, the print head 200 can be translated relative to the printing material under the drive of the drive module 20.

[0048] Optionally, the position detection module 30 can be but is not limited to a grating distance measurement module, a laser distance measurement module or other types of position detection mechanisms.

Thus, whether the print head 200 is correctly moved to the preset printing position can be detected based on the position detection signal of the position detection module 30.

[0049] It can be understood that when the print head 200 is linearly reciprocated under the drive of the drive module 20, the guide rail module 40 can maintain the connection and matching relationship with the print head 200 to provide rigid support for the print head 200 during the movement of the print head 200, thereby facilitating avoiding the problem of shaking of the print head 200 during the movement and improving the movement stability of the print head 200. Meanwhile, the position detection module 30 can detect the position of the print head 200 in real time to ensure the displacement accuracy of the print head 200 and reduce the risk of misalignment of the print head 200, thereby improving the printing accuracy of the print head 200.

[0054] Optionally, the side edge part 422 protrudes towards the side of the linear guide rail 41 from the side of the main body part 421, so that the thickness of the side edge part 422 is greater than the thickness of the main body part 421, and the side edge part 422 has sufficient structural strength. By arranging the threaded holes on the side edge part 422, the threaded holes can have sufficient depth for the fasteners to pass through, so that the housing of the print head 200 can be locked to the side edge part 422 by the fasteners. The threaded holes can be arranged on only one side, or on both side edge parts 422; each side edge part 422 can have only one threaded hole, or two or more threaded holes, which are not limited here.

Moreover, by arranging the in-position detection module 50 on the top plate 12 of the rack 10, the in-position detection module 50 can be arranged away from the side space of the rack 10, so as to achieve in-position detection by using the part of the print head 200 protruding above the top plate 12, thereby reserving sufficient space on the side of the rack 10 for arranging the driving module 20, the guide rail module 40, the position detection module 30 and other functional modules, which realizes reasonable layout of the installation position of the rack 10 and is beneficial to improve the close cooperation of the driving module 100 and the print head 200 and reduce the occupied space of the driving module 20. Of course, the technical solution of the application is not limited to this.
