A motor on a mounting frame drives a screw rod to rotate, the screw rod drives a moving part to reciprocate in a rectangular groove in the mounting frame, a discharging pipe at the bottom of a storage part discharges pigment to an ink dipping roller, a contact part is in contact with the ink dipping roller, and through reciprocating motion, the pigment can be sprayed out of the ink dipping roller. Therefore, the pigment is evenly smeared on the ink dipping roller, and it is guaranteed that the pigment adheres to the ink dipping roller more evenly.

Description

Technical Field

[0001] This utility model belongs to the field of printing press technology, and more specifically, it relates to a printing press with multiple anti-counterfeiting marks. Background Technology

[0002] A printing press is a machine for printing text and images. The principle is as follows: first, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Ink is then applied manually or by the printing press to the areas on the printing plate containing the text and images, and then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thereby reproducing printed materials identical to the printing plate. The invention and development of the printing press has played an important role in the dissemination of human civilization and culture. However, some printed paper needs to have anti-counterfeiting features, which is usually achieved by spraying anti-counterfeiting codes onto the paper as anti-counterfeiting marks.

[0003] Based on existing technology, it has been found that in the use of existing printing presses, the ink rollers are usually immersed in the ink cartridge from the bottom during the dyeing process, resulting in uneven pigment distribution on the ink rollers. In addition, the pigment is usually fixedly added into the ink cartridge, and the pigment has poor flowability inside the ink cartridge, which affects work efficiency. Furthermore, in the use of existing printing presses, a large amount of paper is piled up, and the paper is prone to deformation, which affects the printing effect. There is no flattening structure. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a printing press with multiple anti-counterfeiting marks. This solves the problems of existing printing presses where the ink rollers are typically immersed in the ink cartridge at the bottom during dyeing, resulting in uneven pigment distribution on the rollers. Furthermore, the ink is usually fixedly added to the cartridge, leading to poor ink flow and reduced work efficiency. Additionally, existing printing presses often experience paper accumulation, causing paper deformation and affecting printing quality, and lack a flattening structure.

[0005] This utility model discloses a printing machine with multiple anti-counterfeiting marks, which is achieved by the following specific technical means:

[0013] A motor is installed on the workbench; a heating device is provided on the top right side of the workbench; the workbench is fixedly installed at the bottom of the mounting frame; and the conveyor belt is rotatably installed between the workbench.

[0014] Furthermore, the storage component is provided with a discharge pipe at its bottom; a control valve is provided on the discharge pipe of the storage component; and the contact element has an arc-shaped structure.

[0015] Furthermore, the flattening mechanism includes: a fixing member and a cam;

[0016] The fixing component has a round hole; the fixing component has a rectangular groove at the top center; the fixing component is fixedly installed on the top right side of the workbench; a motor is fixedly installed on the top of the fixing component; the cam is connected to the motor output shaft on the fixing component.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This device includes a screw and a moving part. The screw is connected to a motor on the mounting frame, while the moving part is slidably mounted inside a rectangular groove on the mounting frame. During use, the motor on the mounting frame drives the screw to rotate, which in turn drives the moving part to reciprocate within the rectangular groove on the mounting frame. The discharge pipe at the bottom of the storage component discharges the pigment onto the ink-dipping roller, and the contact component contacts the ink-dipping roller. Through reciprocating movement, the pigment is evenly coated onto the ink-dipping roller, ensuring more uniform pigment adhesion. It eliminates the need to wait for the ink cartridge to be full before starting work, thus improving work efficiency.

[0021] 2. In this device, a cam and a flattening component are provided. The cam is connected to the motor on the fixed component, and the flattening component is slidably installed inside the round hole of the fixed component through rectangular protrusions on both sides of the top. Thus, when in use, the motor on the fixed component drives the cam to rotate, and the arc-shaped protrusion of the cam contacts the roller, thereby driving the roller and the flattening component to move downward and compress the spring. This allows the flattening component to contact the paper and apply a certain pressure, thereby assisting in flattening the paper. Attached Figure Description
