Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a printing roller of a printing machine. Background Art

[0002] In the modern printing industry, the printing roller is a key component of the printing press, and its performance directly affects printing quality and production efficiency. However, over time, the printing function of the printing roller will gradually decline, mainly manifested in problems such as wear of the printed pattern and increased surface roughness. These problems will lead to a decline in the quality of printed products, affecting customer satisfaction and corporate reputation. Currently, a common solution is to replace the entire printing roller, but this not only requires a long time and a lot of labor, increasing production downtime, but also significantly increases the company's operating costs. In particular, replacing the entire roller body will result in a waste of resources and is not in line with the requirements of sustainable development. Therefore, we propose a printing roller for a printing press. Utility Model Content

[0003] The main purpose of the utility model is to provide a printing roller of a printing press, which can effectively solve the problems in the background technology.

[0006] A locking piece is provided on the left side of the connecting cylinder, and the printing roller is coaxially connected to the outside of the connecting cylinder through the locking piece.

[0007] Preferably, the inner surface of the printing roller is provided with card slots on both the front and rear sides thereof and adapted to the card strips, the upper and lower inner walls of the two card slots are provided with positioning holes, and the inner surface of the printing roller is integrally formed with slide strips adapted to the slide slots on both the upper and lower sides thereof.

[0008] By adopting the above technical solution, the printing roller can not only be installed and disassembled quickly and accurately, but also ensure stability and reliability under high-load working conditions.

[0009] Preferably, the clamping slot is slidably connected to the corresponding clamping strip, and the slide strip is slidably connected to the corresponding slide slot to coaxially connect the printing roller to the outside of the connecting cylinder.

[0010] By adopting the above technical solution: the card slots and slides designed inside the printing roller are used in conjunction with the card strips and slides on the connecting cylinder, ensuring that the printing roller can be accurately positioned during installation, avoiding printing quality problems caused by position offset.

[0012] By adopting the above technical solution, the positioning rod in the locking member cooperates with the positioning hole on the printing roller, thereby ensuring stable fixation of the printing roller.

[0013] Preferably, the locking member includes a connecting block, and there are four connecting blocks. The four connecting blocks are respectively slidably connected in four receiving grooves. A spring is fixedly installed at one end of the four connecting blocks, and the spring is fixedly connected to the inner wall of the receiving groove. A positioning rod is fixedly installed at the middle of the end of the connecting block away from the spring. The positioning rod passes through the inner wall of the receiving groove and is slidably connected to the receiving groove. A pull rod is fixedly installed at the left end of each connecting block, and the pull rod is slidably connected to the guide groove.

[0014] By adopting the above technical solution, the pre-tightening force provided by the spring enhances the fixing effect, so that the printing roller is not easy to loosen during the printing process, thereby ensuring the stability of the printing quality.

[0015] Preferably, the diameter of the positioning rod is equal to the diameter of the positioning hole, and the four positioning rods are respectively inserted into the corresponding positioning holes to fix the printing roller on the outer side of the connecting cylinder.

[0016] By adopting the above technical solutions: the efficiency of equipment maintenance and replacement is greatly improved, and production downtime is reduced.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The card slots and slides designed inside the printing roller are used in conjunction with the card strips and slides on the connecting cylinder to ensure that the printing roller can be accurately aligned during installation, avoiding printing quality problems caused by position offset.
