[0002] The embossing device of the gravure printing machine is mainly composed of a loading roller, a feed roller and an embossing roller. The embossing device is the core component of the unit-type gravure printing machine and is responsible for the transmission and embossing of materials. Its main characteristics are high speed and high efficiency.

[0003] The existing publication number CN201950918U is a patent entitled "A high-speed gravure printing machine embossing device". The device is provided with a rubber roller and also includes a central shaft. Discs are fixed at both ends of the central shaft, and three rubber rollers are arranged on the discs. Linear guide pairs are arranged on the wall panels on both sides of the central shaft. A base is fixed on the slider of the linear guide pair. Both ends of the central shaft are fixed on the base. A worm is arranged on the inner side of the base. A worm wheel matching the worm is fixed on the central shaft. Cylinders are connected to the upper part of the base at both ends. Synchronous brake shafts are installed on the wall panels on both sides, and a pneumatic brake device is installed on the outer side of the right wall panel. A synchronous rack is fixed on the back of the base, and a synchronous gear is fixed on the synchronous brake shaft. The three-bowl embossing device can quickly replace the rubber rollers during the printing process, and adjust them in place in sequence according to the requirements of the printed product, which shortens the preparation time for printing and improves work efficiency.

[0004] Although the above-mentioned device has certain conveniences during use, the device is not provided with a limited protection structure, which makes it impossible for the device to distribute appropriate pressure and ensure that the ink is evenly transferred to the surface of the printing plate and the printed matter. It is difficult to reduce problems such as blurring and ink leakage on the printed matter and improve the clarity and color vividness of the printed matter. For this reason, we propose a stamping device with a limited protection structure. Utility Model Content
