[0030] In this embodiment, when it is necessary to splice multiple guide rail assemblies according to the length of the inkjet print, the two push rods 12 are pushed, and the push rods 12 drive the movable plate 10 to move. The first spring 11 is compressed, and the movable plate 10 drives the fixed block 13 to move. The two fixed blocks 13 are inserted into the two fixed grooves 14 on one side of the adjacent support plate 1. The two push rods 12 are released, and under the push of the first spring 11, the movable plate 10 drives the fixed block 13 to move back to the original position. At this time, the fixed block 13 will be stuck in the fixed groove 14, thereby splicing and fixing the two adjacent support plates 1 together. Multiple support plates 1 can be spliced ​​together as needed. The dual-axis motor 5 is started, and the dual-axis motor 5 drives the two rotating rods 6 to rotate. The rotating rod 6 drives the gear 7 to rotate. Since the rack 8 is meshed with the gear 7, the gear 7 rotates and moves. The gear 7 drives the movable base 3 to move along the limit groove 2 through the dual-axis motor 5. The movable base 3 drives the inkjet printer head 15 to move through the adjustment assembly, and the position of the inkjet printer head 15 is adjusted laterally.

[0031] See also Figure 1-Figure 5, as an implementation method for adjusting the height of the inkjet printer head 15: the adjustment component includes a bracket 16 fixedly arranged on the movable base 3, the bracket 16 is fixedly provided with a drive motor 17, the driving end of the drive motor 17 extends into the bracket 16 and is fixedly connected with a screw 18 rotatably connected to the bracket 16, and the screw 18 is threadedly connected with a lifting base 19, the inkjet printer head 15 is installed on one side of the lifting base 19, and the upper and lower ends of the lifting base 19 are respectively provided with vertical plates 20, and a mounting assembly is provided on the vertical plate 20, and the vertical plate 20 is movably connected to a cleaning block 21 through the mounting assembly, an ink tank 22 is provided on the movable base 3, and a pump body 23 is installed on one side of the ink tank 22, and the pump body 23 is connected to the ink tank 22 through a pipe, and a hose 24 is connected between the pump body 23 and the inkjet printer head 15.

[0032] Specifically, the drive motor 17 is started, and the drive motor 17 drives the screw 18 to rotate. Since the screw 18 is threadedly connected to the lifting seat 19, the lifting seat 19 moves along the bracket 16, and the lifting seat 19 drives the inkjet printer head 15 to move, thereby adjusting the height of the inkjet printer head 15. The pump body 23 is started, and the pump body 23 transports the ink in the ink tank 22 to the inkjet printer head 15 through the hose 24 for inkjet printing. Since the inkjet printer head 15 is a prior art, its specific structure and working principle are not described here. While the lifting seat 19 moves, the lifting seat 19 drives the vertical plate 20 to move, and the vertical plate 20 drives the installed cleaning block 21 to move through the mounting assembly. The cleaning block 21 contacts the inside of the thread on the screw 18. With the cooperation of the rotation of the screw 18, the cleaning block 21 cleans the inside of the thread on the screw 18.

[0033] See also Figure 1-Figure 5 , as an implementation method for installing the cleaning block 21: the installation assembly includes a support tube 25 threadedly connected to the vertical plate 20, a turning handle 26 is fixedly provided at one end of the support tube 25, a push plate 27 is movably provided in the support tube 25, a second spring 28 is provided between one side of the push plate 27 and the support tube 25, a push rod 29 is fixedly provided on one side of the push plate 27, and one end of the push rod 29 passes through the support tube 25 and is fixedly connected to the cleaning block 21.

During the entire installation process, under the push of the second spring 28, the push plate 27 moves outward, the push plate 27 drives the push rod 29 to move, and the push rod 29 drives the cleaning block 21 to move, so that the cleaning block 21 moves into the thread of the screw rod 18, so that the cleaning block 21 is connected to the inside of the thread.

[0035] In summary, when the overall equipment is in use:

[0036] When it is necessary to splice multiple guide rail assemblies according to the length of the inkjet printing in the classroom, push the two push rods 12, the push rods 12 drive the movable plate 10 to move, the first spring 11 is compressed, and the movable plate 10 drives the fixed block 13 to move, and the two fixed blocks 13 are inserted into the two fixing grooves 14 on one side of the adjacent support plate 1, and the two push rods 12 are released. Under the push of the first spring 11, the movable plate 10 drives the fixed block 13 to move back to its original position. At this time, the fixed block 13 will be stuck in the fixing groove 14, thereby splicing and fixing the two adjacent support plates 1 together. Multiple support plates 1 can be spliced ​​together according to needs and placed on the wall of the classroom where inkjet printing is required. Start the dual-axis motor 5, the dual-axis motor 5 drives the two rotating rods 6 to rotate, and the rotating rod 6 drives the gear 7 to rotate. Since the rack 8 is meshed with the gear 7, the gear 7 rotates and moves at the same time. The gear 7 drives the movable base 3 to move along the limit slot 2 through the dual-axis motor 5, and the movable base 3 drives the inkjet head 15 to move through the adjustment assembly, and the position of the inkjet head 15 is adjusted laterally.

[0037] When the vertical position of the inkjet head needs to be adjusted, the drive motor 17 is started, and the drive motor 17 drives the screw 18 to rotate. Since the screw 18 is threadedly connected to the lifting seat 19, the lifting seat 19 moves along the bracket 16, and the lifting seat 19 drives the inkjet head 15 to move, thereby adjusting the height of the inkjet head 15, and starting the pump body 23. The pump body 23 transports the ink in the ink tank 22 to the inkjet head 15 through the hose 24 for inkjet printing in the classroom. Since the inkjet head 15 is a prior art, its specific structure and working principle are not described here. At the same time as the lifting seat 19 moves, the lifting seat 19 drives the vertical plate 20 to move, and the vertical plate 20 drives the installed cleaning block 21 to move through the mounting assembly. The cleaning block 21 contacts the inside of the thread on the screw 18. With the cooperation of the rotation of the screw 18, the cleaning block 21 cleans the inside of the thread on the screw 18.

[0038] When the cleaning block 21 needs to be installed, the handle 26 is turned so that the handle 26 drives the support tube 25 to rotate, thereby threading the support tube 25 onto the vertical plate 20, and the support tube 25 drives the push rod 29 and the cleaning block 21 to be installed on the vertical plate 20. During the entire installation process, under the push of the second spring 28, the push plate 27 moves outward, the push plate 27 drives the push rod 29 to move, and the push rod 29 drives the cleaning block 21 to move, so that the cleaning block 21 moves into the thread of the screw rod 18, so that the cleaning block 21 is connected to the inside of the thread.

[0039] A controller is installed on the ink tank 22, and all electrical equipment in the entire device is controlled by the controller. Since the equipment matched with the controller is a commonly used equipment, its control principle and line connection are all existing well-known and mature technologies, and its electrical connection relationship and specific circuit structure will not be repeated here.

[0040] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
