TECHNICAL FIELD
[0001] The utility model relates to printing machine technical field, concretely is a printing machine cylinder structure and printing machine thereof. BACKGROUND
[0002] In the process of the continuous development of the printing industry, the performance of the printing machine plays a decisive role in printing quality and production efficiency, and the printing machine cylinder structure, as one of the core components of the printing machine, is self-evident in importance. The traditional printing machine cylinder structure has exposed many problems that are difficult to overcome in the long-term use process, and has been unable to meet the increasingly diversified and sophisticated needs of today's printing industry.
[0003] In material application, the density of the traditional cylinder material is larger, so that the overall weight of the cylinder is heavier. This not only increases the load of the motor and other power components, resulting in a substantial increase in energy consumption, but also in the process of starting, stopping and speed changing, due to the large inertia, the response speed is slow, and it cannot quickly adapt to the requirements of speed change of different printing tasks, which seriously restricts the improvement of production efficiency. In view of this, we propose a printing machine cylinder structure and printing machine to solve the existing problems. UTILITY MODEL CONTENT
[0004] The utility model aims at providing a printing machine cylinder structure and printing machine to solve the problems raised in the above background technology.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a printing machine cylinder structure and printing machine, comprising a printing machine mounting frame, a printing cylinder, a rotating shaft, a mounting block, an end plate and a reinforcing member, a plurality of rotating shafts are arranged on the printing machine mounting frame, the rotating shafts are provided with an end plate between the printing machine mounting frame, and the mounting block is annularly arranged on the end plate, and the printing cylinder is fixedly connected with the end plate through the mounting block.
[0006] Preferably, the printing cylinder and the end plate are matched with each other, and the printing cylinder can be provided with a second layer of inner annular reinforcing member.
[0007] Preferably, the printing cylinder is made of carbon fiber material, and the printing cylinder can be single or double layer structure, and the printing cylinder is applied to intermittent rotary offset press.
[0008] Preferably, the printing cylinder can be cylindrical or D-shaped sectional semicircular barrel structure.
[0009] Compared with the prior art, the utility model has the beneficial effects that:
[0010] 1. Through the unique ring-shaped clamping groove design of the end plate, the mounting block is tightly matched with the end plate, so that the printing cylinder can be accurately positioned and strictly follow the predetermined track when rotating with the end plate. This accurate rotation control ensures that the printing cylinder accurately contacts the printing material during the printing process, greatly reduces the printing deviation and pattern blur, and significantly improves the yield of products with high requirements for pattern position accuracy in packaging printing and label printing, thereby ensuring the stability and reliability of the printing quality.
[0011] 2. The reinforcing members uniformly distributed along the inner wall of the printing cylinder effectively enhance the structural strength of the printing cylinder. When facing complex pressure, friction and strong centrifugal force generated by high-speed rotation during the printing process, the reinforcing ribs can uniformly disperse the stress and prevent the printing cylinder from deforming. This not only improves the stability of the printing cylinder under various working conditions, but also greatly prolongs the service life of the printing cylinder, reduces the failure frequency of the equipment due to structural problems, reduces the maintenance cost, and improves the reliability and durability of the equipment.
[0012] 3. The printing cylinder is made of carbon fiber material, which has high strength and low density. The printing cylinder can significantly reduce its own weight while ensuring structural strength. This makes the load of the motor and other power components of the printing machine significantly reduced during operation, improves the energy utilization efficiency, and realizes energy-saving operation. At the same time, the lighter printing cylinder responds more quickly during start, stop and speed change, and can better adapt to the requirements of rapidly changing printing tasks, thereby improving production efficiency. In addition, the single-layer and double-layer structure design of the printing cylinder gives the equipment great flexibility. According to different printing processes and working environment requirements, corresponding functional components can be arranged in the double-layer structure, thereby expanding the application range of the equipment and improving its market competitiveness.
[0013] 4. The cylindrical printing cylinder is suitable for most conventional printing processes, and its surface can uniformly transfer ink and pressure to ensure the uniformity of printing. The printing cylinder with a D-shaped cross-section and a semicircular barrel structure may have advantages in some special printing equipment or processes. This shape of the printing cylinder can better adapt to the layout and working requirements of the equipment to adapt to different working condition application scenarios.
