Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a high-precision and high-efficiency plate-making mechanism. Background Art

[0002] In traditional technology, silk screen printing plates are made by exposure and development methods. Among them, the power of the plate-making machine is high, the energy consumption is large, and the negative film becomes a waste product after plate-making, which not only wastes limited resources but also pollutes the environment. The silk screen printing plates made by this method have poor image accuracy and cannot reflect real pattern information. Therefore, laser plate-making technology has begun to be used to make silk screen printing plates. Due to the vibration generated during the movement of the laser module, the photosensitive resin film lines on the silk screen printing plate are thick and have large height sawteeth, making it difficult to meet people's needs for delicate patterns. In addition, the existing plate-making mechanism has poor movement stability and is prone to plate-making misalignment.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a high-precision silk screen printing laser plate-making machine [CN202110432935.7], which includes a laser cross beam, a silk screen printing plate, a moving flat plate, a control system, a left-right moving lead screw, a left-right moving guide rail, a front-back moving motor, a front-back moving lead screw, an intermediate support plate, a front-back moving guide rail, a left-right moving motor, and a frame. The silk screen printing plate is fixed on the moving flat plate, and the moving flat plate can move back and forth and left and right. The laser module is installed on the laser cross beam, and the laser cross beam is installed on the frame, and the laser module is fixed.

[0004] The above solution solves to a certain extent the problem that the laser module of the plate-making equipment in the existing technology generates vibration during movement, which is prone to thick photosensitive resin film lines and large height sawteeth. However, this solution still has many deficiencies, such as poor movement stability and prone to plate-making misalignment. Summary of the Invention
