Technical Field

[0001] The invention relates to the technical field of roller printing, and in particular to a roller printing device. Background Art

[0002] A roller printing device is a mechanical device used for textile printing. It transfers patterns or colors to fabrics through rotating rollers. This device usually includes multiple rollers, each of which is engraved with specific patterns or text. During the printing process, the rollers are in contact with the fabric and the pattern is accurately printed on the fabric through pressure and pigment transfer. Roller printing devices are widely used in the textile industry due to their high efficiency and good pattern repeatability.

[0003] Printing wheels usually have two specifications: diameters of 530 mm and 640 mm. Since the roller is usually fixed on a frame, the printing wheel cannot be replaced. Therefore, if two specifications of wallpaper are to be printed, two production lines must be set up, which not only repeats investment but also seriously occupies factory buildings. Based on these problems, Chinese patent CN106113906A discloses a roller printing device, which improves the fixing method of the roller so that it can be replaced together with the printing roller, thereby realizing printing operations of two specifications without the need to use two production lines.

[0004] When the printing wheel is rotating, the rotating arm is likely to collide with the ink pipe, causing the printing wheel to stop rotating. This not only affects the normal operation of the roller printing, but also the collision of the rotating arm with the ink pipe may cause the ink pipe to deform or rupture, seriously affecting the use efficiency of the roller printing device.
