Description

Technical Field

[0001] The utility model relates to the technical field of book printing equipment, in particular to a flattening mechanism for printing turbine book signatures. Background Art

[0002] Printing wheel press usually refers to the printing machinery and equipment used in the printing industry for printing various materials, such as paper, cloth, etc. Printing wheel presses can be divided into different types such as flatbed printing presses, gravure printing presses, letterpress printing presses, flexographic printing presses, etc. according to different printing methods and needs. The flattening mechanism of the printing wheel press is usually used to adjust and control the pressure and flattening effect of the printing wheel on the book during the printing process. The design and function of this mechanism help to ensure the quality of printed products and production efficiency.

[0003] The existing printing machine book flattening equipment generally does not have a mechanism for positioning the book. Due to the lack of a book positioning mechanism, the book is prone to position displacement or misalignment during the flattening process, affecting the printing quality, making the final product not meet the requirements, and increasing production costs. At the same time, the operator needs to manually adjust the position of the book, which increases the complexity of the operation and the adjustment time, reduces production efficiency, and affects the production schedule and output. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing printing machine book signature flattening equipment generally does not have a mechanism for positioning the book signature, which affects the printing quality, production progress and output.

[0006] Through the above technical solution, the connecting shaft cooperates with the limiting hole to realize the limiting rod to clamp and position the books of different widths. It has a wide range of applications and prevents the books from sliding or shaking during the flattening process, which helps to reduce the vibration and impact of the equipment and reduces the risk of wear and damage to the equipment.

[0009] The utility model is further configured such that symmetrical sliding grooves are respectively opened on both sides of the fixing frame, a buffer spring is arranged in the first through hole, two ends of the buffer spring are respectively fixedly connected to the fixing frame and the sliding plate, and a bearing is sleeved on one end of the roller away from the second motor, and the bearing is fixedly connected to the sliding plate.

[0010] Through the above technical solution, the bearing can effectively reduce the friction between moving parts, help reduce the energy consumption of mechanical equipment, improve overall efficiency, reduce wear, extend the service life of mechanical equipment, reduce maintenance frequency and repair costs, and improve the reliability and stability of the equipment. The buffer springs on both sides are used to better provide uniform pressure, and can make appropriate adjustments to the flattening roller according to the thickness and hardness of the paper to ensure the flattening effect.

[0012] Through the above technical solution, the hydraulic cylinder can control the flattening roller to move up and down, and can be adjusted according to the thickness of the book, ensuring a uniform flattening effect on the book with different thicknesses, thereby improving the applicability and flexibility of production.

[0013] The utility model is further configured that the two fixing rods are respectively provided with second through holes, and the bottom of the workbench is fixedly connected with a plurality of supporting legs.

[0014] The beneficial effects of the utility model are as follows:

[0015] The utility model discloses a book clip that is clamped and positioned on the printing plate, and the book clip that is clamped and positioned on the printing plate can be prevented from sliding or shaking during the flattening process, so that the flattening roller can evenly apply pressure on the book clip, which helps to improve the printing quality and avoid the problems of blur, missing printing or unstable printing position.
