The piston rod of the sliding arm cylinder 109 of the present invention is fixedly connected with the sliding arm 111 through the pin shaft 110 .

The working principle of a circular concave flexible trinity wallpaper printing device of the present invention is as follows: when the rotary screen printing unit 1 is working, if the mounting seat is at 640 and the rotary screen 105 is working, slide the rotary screen mounting seat 103 to an appropriate position, and then only need to The sliding arm cylinder 109 is controlled by the electromagnetic valve to push the sliding arm 111 to slide on the idler bracket 107, and the idler roller 115 is driven to move, and meshes with or separates from the 640 round screen 105. In this working mode, the idler cylinder 113 does not work; When the screen version is switched to 530 rotary screen 106, ensure that the position of the rotary screen mounting seat 103 remains unchanged, that is, the center position B ₁ B ₂ of the rotary screen screen remains unchanged, and only need to control the solenoid valve to simultaneously feed the sliding arm cylinder 109 Air is supplied to the idler cylinder 113, and the idler 115 is pushed to mesh with the 530 round screen 106 to complete one-key switching, saving time and effort.

When the integrated rotary screen printing mechanism of the present invention is working, by adjusting the length of the screw rod of the front limiter 120, it is against the swing arm 117. Sliding inside drives the swing arm 117 to rotate and swing around the center of the swing arm rotating seat 116, and will not exceed the top of the screw rod, so that the meshing position of the idler and the rotary screen can be guaranteed. As long as the position of the rotary screen and the scraper 104 is fixed, the It can ensure that the cylinder screen and the idler roller 115 mesh at the same position each time. At the same time, when the cylinder screen screen and the idler roller 115 mesh, the oil pressure buffer 119 will produce resistance with the sudden forward movement of the swing arm 117, reducing the meshing time. The impact force of the roller 115 on the cylinder makes the meshing smooth and accurate, prolongs the life of the cylinder 121 to the greatest extent, and reduces noise.

The rotary screen bottom plate 101 of the present invention is the installation reference of other parts of the rotary screen printing unit. The rotary screen bottom plate 101 ensures that the upper and lower end surfaces are parallel to the front and rear large surfaces respectively during processing, and the upper and lower end surfaces are vertical to the front and rear large surfaces, so this part is installed At the same time, other components can ensure the installation accuracy of each mechanism and the cooperation accuracy requirements between each mechanism through the rotary screen bottom plate 101 . Therefore, this integrated rotary screen printing mechanism can be installed separately. After the installation is completed, it is assembled on the reference plane A of the large wall panel 5 as a whole, which improves the assembly efficiency to a greater extent and simplifies the assembly process.

The transmission device of the present invention drives the rotary screen drive head 213 to rotate during operation, thereby driving the rotary screen or the flexo plate roller to rotate, which solves the problem of long transmission route of the mechanical shaft, high precision requirements for each transmission part, and processing and assembly error requirements. strict question.
