Technical Field
[0001] This utility model belongs to the field of printing machinery technology, and more specifically, it relates to a pressing device between printing rollers of a color film printing machine. Background Technology
[0002] In the printing process, the clamping device plays a crucial role. Its main function is to ensure that the printing material (such as fabric) passes smoothly through the printing area, thereby guaranteeing the quality and consistency of the print. The clamping device typically includes one or more pressure rollers that apply mechanical pressure to keep the fabric pressed tightly against the printing components, such as the printing rollers or printing plate. In color film printing machines, the design of the clamping device between the printing rollers is essential for improving printing quality and production efficiency. Existing technologies may have some shortcomings in the clamping devices of printing machines, such as a lack of adjustability, resulting in insufficient flexibility when clamping fabrics of different thicknesses or materials, affecting clamping efficiency and printing quality. Therefore, developing new clamping devices has become a key direction for improving the performance of printing machines. In summary, the technical background of the clamping device between the printing rollers of color film printing machines involves the basic working principle of the printing machine, the importance of the clamping device, and the problems existing in the current technology. The development of new clamping devices aims to solve these problems by improving adjustability, automated control, and durability, thereby enhancing the overall performance of the printing machine and the printing quality.

[0025] As attached Figure 1 To be continued Figure 5 As shown:
[0026] This utility model provides a pressing device between printing rollers of a color film printing machine, including a main frame 1, a rotating clamping rod A2, a printing roller 3, and a side frame 4. Each side of the main frame 1 has a set of connecting mounts, and each of the connecting mounts has two sets of sliding connecting grooves. The rotating clamping rod A2 has a set of circular auxiliary sliding rings on its front and rear sides. The circular auxiliary sliding rings on the front and rear sides of the rotating clamping rod A2 are slidably connected to the two sets of sliding connecting grooves on the connecting mounts on both sides of the main frame 1. Each side of the side frame 4 has a set of connectors, and each of the connectors on both sides of the side frame 4 has a set of sliding grooves. The sliding grooves on the connectors on both sides of the side frame 4 are slidably connected to the circular auxiliary sliding rings on both sides of the rotating clamping rod A2. A set of circular connecting holes is located between the main frame 1 and the side frame 4. Each side of the printing roller 3 has a set of circular connecting rods, and the circular connecting rods on both sides of the printing roller 3 are rotatably connected to the circular connecting holes between the main frame 1 and the side frame 4.
[0027] The device main frame 1 and the device side frame 4 are each provided with a set of sliding connection grooves on both sides of the lower part, and the rotating clamping rod B5 is slidably connected in the sliding grooves of the lower part of the device main frame 1 and the device side frame 4 to achieve smooth clamping.
[0028] The rotating clamp A2 has a set of circular connecting rods on both the front and rear sides, and the circular connecting rods on the front and rear sides of the rotating clamp A2 are rotatably connected to the connector 602, so that it can rotate and rise.
[0029] The connector 602 has a set of circular connection holes on both the upper and lower sides, and a set of limiting switches 6 are rotatably connected to the circular connection holes on both the upper and lower sides of the connector 602, which are locked into the limiting holes.
