Technical Field

[0001] The utility model relates to the technical field of paper towel production equipment, and more specifically, to a spraying device used for paper towel processing. Background Art

[0002] Roll-type tissues, box-type tissues, soft-pack tissues, and other types of tissues often require some surface processing, which is more beautiful and has higher added value than pure white tissues. Tissue materials are soft and have strong absorption and diffusion properties.

[0003] For example, the public authorization announcement number CN215705081U discloses an automatic paper towel spraying device, which uses a combination of spraying and scraping to accurately control the amount of ink, and the scraping component can automatically adjust after wear, maintaining the accuracy of ink control for a long time, ensuring the quality of pattern production, avoiding excessive ink resulting in blurred patterns, avoiding ink waste, and reducing production costs.

[0004] In the above solution, the print head is fixed to the printing roller by bolts. Since there are multiple print heads, when replacing them, the bolts of multiple print heads need to be removed, replaced, and then the new print heads need to be installed, which is quite time-consuming. Utility Model Content

[0008] The printing device is movably connected to the printing roller body, and the printing device includes an endless belt and a plurality of printing heads connected to the endless belt. The printing roller body is provided with an annular groove for placing the endless belt.

[0009] The printing head is connected to the annular belt by mortise and tenon joints. Connectors are provided at both ends of the annular belt. The connectors include a frame and a connecting rod connected to the frame. A mounting block connected to the connecting block is provided on the annular groove. A slot is provided on the side wall of the mounting block. One end of the connecting rod extends into the slot.

[0010] The frame body is movably connected to the connecting rod.

[0011] The utility model is further configured as follows: mounting holes are opened at both ends of the frame, springs are arranged in the mounting holes, connecting plates are arranged in the mounting holes, one end of the spring is fixedly connected to the connecting plate, and the other end is connected to the connecting rod.

[0012] The utility model is further configured as follows: a sphere is provided at the end of the connecting rod, and an anti-slip pad is provided on the surface of the sphere.

[0013] The utility model is further configured as follows: the upper end surface of the mounting block is provided with a movable hole connected with the slot hole, and the connecting rod extends into the slot hole and is flush with the movable hole.

[0014] The utility model is further configured as follows: the inner wall of the slot hole is provided with a plurality of anti-slip lines.

[0015] The utility model is further configured as follows: the annular belt is made of rubber material, and the annular belt is soft and has deformation capability.

[0016] The utility model is further configured as follows: a plurality of grooves are opened on the annular belt, a convex block is provided on the printing head, the convex block is embedded in the groove, an elastic ball is provided on the side wall of the convex block, and the elastic ball contacts the inner wall of the groove.

[0017] Compared with the shortcomings of the prior art, the beneficial effects of the present invention are:

[0018] By adding an annular belt, when a different printing pattern needs to be changed, you only need to remove the annular belt. The disassembly is relatively convenient. It is fixed by connecting the connecting rod and the slot hole, and the connecting rod is provided with a ball that contacts the slot hole, making it more stable. Furthermore, the printing head is connected to the annular belt by mortise and tenon. When the printing head is damaged and needs to be replaced, only a single printing head needs to be replaced.
