Description

Technical Field

[0001] The utility model belongs to the technical field of rotating devices of printing machines, and in particular relates to a rotating device of a direct-injection digital printing machine. Background Art

[0002] In jet printing, small droplets of dye are sprayed and stay on the precise position of the fabric. The nozzles used to spray the dye and the pattern formation can be controlled by computers, and complex patterns and precise pattern cycles can be obtained. In jet printing, the delay and cost increase caused by engraving rollers and making screens are eliminated, which is a competitive advantage in the fast-changing textile market. The jet printing system is flexible and fast, and can quickly switch from one pattern to another. The existing printing machines on the market generally use motors to drive the first and second shafts to rotate. During printing, the fabric needs to maintain a certain degree of tension to ensure the quality of printing. However, the synchronization of the rotation of the first and second shafts is not well controlled, so the fabric will move too fast or too slow, and the fabric moving too fast or too slow may cause printing failure.

An inner cavity is opened inside the right side of the mounting frame, and a transmission shaft that passes through the mounting frame and is located in the inner cavity is fixedly installed on the output end of the driving motor. A driving gear is sleeved on the side wall of the transmission shaft. Three groups of first mounting shafts are movably installed in the inner cavity, and transmission gears are fixedly installed on the first mounting shafts. A second mounting shaft is movably installed at the bottom of the inner cavity. In the utility model, in the rotating device of the direct-injection digital printing machine, the upper pressing roller and the lower pressing roller are driven to rotate in opposite directions at the same speed, and the rotation of the upper pressing roller and the lower pressing roller can make the cloth between the upper pressing roller and the lower pressing roller move at a uniform speed.

[0004] The above technical solution utilizes the driving gears on the transmission belt and the multiple mounting shafts meshing with each other at both ends to mesh and connect them to make them rotate synchronously. However, since the driving gears are meshingly connected with the two sides of the transmission belt respectively, the two driving gears on the same side are prone to collision during rotation. At the same time, since the multiple rotating shafts are fixedly installed by bearings, the printing materials with a cylindrical structure cannot be installed and removed from the rotating shafts, affecting the normal use of the printing machine.
