[0030] In the embodiment of the utility model, the connector 3 is driven to move up and down by the telescopic action of the air cylinder 6, and then the lifting slider 4 is sliding in the cooperating lifter 2, the height of the feeding roller 5 is adjusted, when the air cylinder 6 is extended or retracted, the connector 3 moves up and down, the movement of the connector 3 drives the lifting slider 4 fixed thereto to slide in the cooperating lifter 2, thereby adjusting the height position of the feeding roller 5, which can quickly and accurately adjust the pressure between the rollers, and ensure that the pressure can be adjusted instantly according to different materials and thicknesses of the printing material during the printing process, thereby improving the printing quality and efficiency.

[0031] For details, please refer to Figures 1-4 The rear ends of the two connectors 3 are respectively fixedly connected with two rotating shafts 7, and the two sides of the feeding roller 5 are respectively provided with two rotating grooves 8, and the two rotating grooves 8 are respectively rotationally connected to the circumferential surfaces of the two rotating shafts 7.

[0032] In the embodiment, the feeding roller 5 can rotate around the rotating shaft 7 through the rotational connection of the rotating shaft 7 in the rotating groove 8, when the connector 3 moves up and down under the action of the air cylinder 6, the rotating shaft 7 and the feeding roller 5 are driven to ascend and descend synchronously, the height of the feeding roller 5 is adjusted, and the design ensures that the feeding roller 5 can still maintain a stable rotating state at different height positions, improves the stability and precision in the printing process, and reduces the printing defects.

[0033] For details, please refer to Figures 1-4 The two sides of the air cylinder 6 are respectively fixedly connected with multiple first limiting fixers 9, the upper ends of the two device supports 1 are both fixedly connected with a top plate 10, and the two side ends of the top plate 10 are respectively fixedly connected with multiple first limiting fixers 9.

[0035] For details, please refer to Figures 1-4A plurality of first sliding grooves 11 are provided in each of the plurality of cooperating lifters 2 , and two lifting sliders 4 are slidably connected in each of the plurality of first sliding grooves 11 .

[0036] In this embodiment: the lifting slider 4 is slidably connected in the first sliding groove 11. When the cylinder 6 drives the connector 3 to move up and down, the connector 3 slides in the first sliding groove 11 through the lifting slider 4 to achieve height adjustment of the loading roller 5. This design ensures the stability and accuracy of the loading roller 5 during the lifting process.

[0037] For details, please refer to Figures 1-4 The outer surfaces of the two device supports 1 are respectively fixedly connected to two second limit fixtures 12, and the two second limit fixtures 12 are respectively rotatably connected to two printing fixed rollers 13, and the circumferential surfaces of the two printing fixed rollers 13 are fixedly connected to printing rollers 14.

[0041] The working principle and usage process of the utility model: first, confirm that the two device supports 1 have been installed in place, and then start the cylinder 6. The extension and contraction of the cylinder 6 drives the connector 3 to move up and down, and the connector 3 then drives the lifting slider 4 to slide in the matching lifter 2, thereby realizing the height adjustment of the feeding roller 5. A plurality of first limit fixtures 9 are fixed on both sides of the top plate 10. These fixtures limit the lateral movement of the cylinder 6 to ensure that it only extends and contracts in a straight line direction, thereby ensuring the vertical lifting of the connector 3, so that the feeding roller 5 can accurately adjust the height. Finally, through the restriction of the second limit fixture 12, the printing fixed roller shaft 13 rotates within the set range to ensure the stability and accuracy of the printing roller 14 during operation. By using this device, the problem that the traditional printing roller cannot achieve lifting adjustment is solved, thereby avoiding the situation where the printing quality is reduced. The inability to accurately adjust the pressure between the rollers will lead to uneven pressure during printing, which in turn affects the quality of the printed product, and may cause problems such as uneven ink distribution, blurred image, and ghosting.
