[0002] In today's rapidly developing printing industry, thermal plate-making machines have become the mainstream equipment for modern printing plate-making due to their advantages such as fast imaging speed, high quality, and environmental friendliness. They are widely used in packaging printing, book printing, and commercial printing. During the thermal plate-making process, the flatness of the plate material plays a decisive role in the plate-making quality.
[0003] Existing anti-warping devices for thermal plate-making machines all use guide rollers to facilitate the conveying of the plate material. However, the spacing of the existing pressure rollers is not adjustable, making them unsuitable for different types of plate materials and resulting in poor performance during use. Improvements are needed. Utility Model Content

[0008] Preferably, the hollow column has a through hole on its front side, the diameter of which is adapted to the diameter of the connecting pipe. The through hole allows the connecting pipe to extend into the interior of the hollow column and connect to the front side of the internal connecting pipe, ensuring the normal operation of the device.
[0009] Preferably, a connecting pipe is fixedly connected to the back of the air pump. The connecting pipe extends through the front of the hollow column and connects to the front of the inner connecting pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The anti-warping device of this thermal plate-making machine is equipped with a transmission limiting component. When the air pump is started, it generates negative pressure suction. With the help of the connecting pipe, the suction is extended into the interior of the connecting pipe. Multiple downward air paths are generated at the diversion suction pipe to adsorb the plate and limit the position to prevent displacement. The device can also be driven by a stepper motor to rotate the hollow column to adjust the orientation of the diversion suction pipe, adapting to the processing of different plates.
[0015] 2. The anti-warping device of this thermal plate-making machine is equipped with a lifting limit component. During use, the mounting parts can be screwed to lock it. The number of counterweights can be manually increased or decreased, or different weights and specifications of counterweights can be replaced, according to the thickness, material, and actual warping of the plate. This adjusts the pressure of the pressure rollers on the plate. The pressure rollers rely on their own weight and the weight of the counterweights to evenly press the plate onto the transmission platform, effectively suppressing the upward warping tendency of the plate caused by uneven heating. This makes the spacing of the pressure rollers adjustable, allowing it to be used with different types of plate materials. Attached Figure Description
