Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and more particularly to a vehicle-mounted air-conditioning cover printing machine. Background Art

[0002] A printing press is a machine used to print text and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its working principle is as follows: the text and image to be printed are first made into a printing plate and mounted on the printing press. Ink is then applied manually or by the printing press to the areas of the plate where the text and image appear. The ink is then transferred directly or indirectly to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), creating a printed product identical to the printing plate.

[0003] Patent authorization number CN212889390U discloses a new printing press, including a frame, a plate roller, a pressure roller located above the plate roller, and a pigment cylinder located below the plate roller. A channel for the printed matter to pass through is formed between the plate roller and the pressure roller. The pressure roller includes a roller and a roller shaft. The frame is provided with a slot for the roller shaft to pass through. The two ends of the roller shaft are located in the slot and can slide up and down. Connecting rods are provided at both ends of the roller shaft. A support plate is provided above the corresponding slot of the frame. The support plate has a movable opening for the connecting rod to pass through. One end of the connecting rod passes through the movable opening and is connected to a baffle. Two springs are provided between the baffle and the support plate. The springs are located at both ends of the baffle. The springs drive the connecting rod to move toward the roller shaft, thereby driving the pressure roller toward the plate roller. After the improvement, the pressure roller has the function of automatically adjusting its height position, making the printing press suitable for printing printed matter of different thicknesses.

[0004] However, existing printing machines can only print on flat workpieces. For example, patent authorization number CN212889390U discloses a new type of printing machine, but it cannot achieve normal printing on workpieces with curved surface structures, such as vehicle air-conditioning covers. In order to be able to print on products with curved surface structures, we have proposed a vehicle air-conditioning cover printing machine to solve the above-mentioned problems.
