Description

[0001] This divisional application has the patent application with the application number 2023231249369, the application date of November 20, 2023, and the title of "A Printing Grid for a Printing Press" as the parent case. Technical Field

[0002] The utility model relates to the field of printing presses, specifically a printing grid for a printing press that is convenient for maintenance. Background Art

[0003] As is well known, modern printing presses generally consist of mechanisms such as plate loading, inking, impression, and paper feeding (including folding). Its working principle is as follows: First, the text and images to be printed are made into printing plates and installed on the printing press. Then, ink is applied to the areas with text and images on the printing plate manually or by the printing press, and then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating the same printed matter as the printing plate. The invention and development of printing presses play an important role in the spread of human civilization and culture; in screen printing technology, the use of grids is crucial. A printing grid refers to a device that widely supports and fixes printing screens in the printing industry.

[0004] In Chinese Utility Model Patent Application No.: CN2020210542.9, a printing grid of a printing press is disclosed. The device includes a fixing plate and a frame plate. Two sets of symmetrically arranged sleeves are fixedly connected inside the fixing plate. The center of the top surface of the fixing plate is fixedly connected with a fixing block, and a motor is fixedly connected to the top surface of the fixing block. The output rotating shaft of the motor is fixedly connected with two driving wheels. Both ends of the top surface of the sleeve are fixedly connected with two support frames. Rotating shafts are arranged at both ends above the sleeve. Driving wheels adapted to the driving wheels are fixedly connected to the outer surfaces of the two rotating shafts. Gears are fixedly connected to both ends of the two rotating shafts. For the printing grid of this printing press, by setting the motor, driving wheel, rotating shaft, driven wheel, gear, tooth groove, arc groove, and sliding rod, a single motor is used to drive four sliding rods to perform lifting movements simultaneously, effectively reducing costs and facilitating the control of the lifting height and precision of the frame plate, thereby improving the printing precision. The frame plate of this device is directly set on the top of the sliding rod, making disassembly and installation relatively inconvenient. Therefore, it is not convenient for disassembly maintenance or cleaning, and its practicality is poor. Summary of the Utility Model
