Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrugated paper production technology, specifically to a servo corner cutting mechanism for a corrugated printing machine. Background Technology
[0002] In the printing and packaging industry, printing grooving and corner cutting knives are key equipment for packaging forming. Traditional printing grooving and corner cutting knives typically have their corner cutting components installed in close contact with the grooving knife, and the grooving and corner cutting processes are completed simultaneously by rotating the knife disc.
[0003] However, this type of corner-cutting blade structure, due to its off-side mounting on the cutter head, experiences weight imbalance under high-speed operation, leading to severe vibrations. This vibration not only significantly affects the forming effect of packaged products but also causes a substantial decrease in processing precision, making it difficult to meet increasingly stringent packaging quality requirements. Simultaneously, the connection between the corner-cutting cross blade and the grooving blade is prone to wear after prolonged, high-frequency operation. Increased wear can cause problems such as incomplete cuts and burrs in the corner-cutting process, reducing production efficiency and increasing the defect rate and subsequent processing costs.

[0023] Specifically, in this embodiment, the servo corner cutting mechanism of the corrugated printing machine is driven by a drive component to rotate the corner cutting half shaft 31. The rotation of the corner cutting half shaft 31 drives the corner cutting cross blade 54 to rotate around the corner cutting half shaft 31 to complete the corner cutting action. During corner cutting, the corner cutting cross blade 54 is embedded in the rubber washer 22 of the corner cutting rubber wheel 21 to achieve the corner cutting effect. In addition, the paper feeding idler wheel 42 is set opposite to the corner cutting rubber wheel 21. The paper feeding idler wheel 42 and the corner cutting rubber wheel 21 cooperate to provide support for paper feeding and corner cutting.
[0024] This embodiment describes a servo corner-cutting mechanism for a corrugated printing machine. The first blade holder 1 is rotatably equipped with multiple first transmission wheels 71; the first blade holder 1 is also rotatably equipped with multiple second transmission wheels 72 directly opposite the first transmission wheels 71. This arrangement facilitates the transport of cardboard through the cooperation of the first transmission wheels 71 and the second transmission wheels 72.
[0025] The servo corner cutting mechanism of the corrugated printing machine described in this embodiment includes a servo motor 6 disposed on the second blade holder 3, a first pulley 61 connected to the output end of the servo motor 6, a second pulley 62 connected to one end of the corner cutting half shaft 31, and a synchronous belt 63 disposed between the first pulley 61 and the second pulley 62.
[0026] Specifically, during use, the servo motor 6 is started, and the servo motor 6 drives the corner cutting half shaft 31 to rotate through the first pulley 61, the synchronous belt 63 and the second pulley 62. The rotation of the corner cutting half shaft 31 drives the corner cutting cross blade 54 to rotate around the corner cutting half shaft 31 to complete the corner cutting action. During corner cutting, the corner cutting cross blade 54 is embedded in the rubber washer 22 of the corner cutting rubber wheel 21 to achieve the corner cutting effect.
[0027] The servo corner-cutting mechanism of the corrugated printing machine described in this embodiment includes a first angular contact ball bearing 32 between the inner wall of the bearing seat 41 and the outer wall of the corner-cutting half-shaft 31. This arrangement ensures a stable and reliable overall structure.
[0028] The servo corner cutting mechanism of the corrugated printing machine described in this embodiment includes a second angular contact ball bearing 43 between the outer wall of the bearing seat 41 and the inner wall of the paper feeding idler wheel 42. This arrangement ensures a stable and reliable overall structure.
[0029] This embodiment describes a servo corner-cutting mechanism for a corrugated printing machine. The first blade holder 1 is equipped with a wheel seat 11; a first blade shaft 12 is rotatably mounted within the wheel seat 11; a third angular contact ball bearing 13 is provided between the wheel seat 11 and the first blade shaft 12; the first blade shaft 12 is connected to a corner-cutting rubber wheel 21. This configuration ensures a stable and reliable overall structure.
[0030] The servo corner cutting mechanism of the corrugated printing machine described in this embodiment has a first fixed arm 51 at one end of the fixed base 5; a second fixed arm 52 at the other end of the fixed base 5; and the middle part of the fixed base 5 is connected to the other end of the corner cutting half shaft 31.

[0032] Specifically, in this embodiment, the servo corner cutting mechanism of the corrugated printing machine is driven by a drive component to rotate the corner cutting half shaft 31. The rotation of the corner cutting half shaft 31 drives the corner cutting cross blade 54 to rotate around the corner cutting half shaft 31 to complete the corner cutting action. During corner cutting, the corner cutting cross blade 54 is embedded in the rubber washer 22 of the corner cutting rubber wheel 21 to achieve the corner cutting effect. The entire corner cutting process is achieved by the acceleration and deceleration or deceleration and acceleration of the servo motor 6. The two corner cutting cross blades 54 correspond to the front corner and the back corner of the cardboard, respectively.
[0033] The servo corner cutting mechanism of the corrugated printing machine described in this embodiment, by separating the servo corner cutting mechanism, achieves front and rear corner cutting of different specifications of cardboard through servo control and flying shear principle. The lightweight design and uniform weight distribution reduce structural vibration during high-speed operation, optimize the corner cutting effect, and fundamentally solve the problem of corner adhesion. At the same time, the component structure is easy to maintain and replace. It avoids the imbalance caused by the slotting knife when the traditional corner cutting cross knife 54 is arranged, and improves the stability of slotting. In addition, by setting an independent servo motor 6 for corner cutting, a single structure can be used for corner cutting processes of various carton sizes. Compared with the corner cutting structure of the slotting part of the printing machine, the problem of incomplete corner cutting is fundamentally solved by independent corner cutting and cross-cutting of knife marks. At the same time, through modular design, the knife holder 53 is easy to adjust and replace, and maintenance is more convenient.
